If there is no data transmission and reception within several short DRX cycles that are configured in advance, the Long DRX state is entered.
- the term "Long DR" indicates that the UE will operate according to the Long DRX setting parameters such as the Long DR period, the routine activation time point, and the length of time.
- the UE when the UE enters the Short DRX state, periodically wakes up to listen to its own scheduling command (ie, in a routine activation state), as shown in FIG. 1, when the on Duration Timer starts, the routine activation state is entered. . If the scheduling command of the new data transmission of the eNB is received, the drx-Inactivity Timer is started, and the trigger activation state is entered, as shown in FIG. 1 , which may still be in the routine activation state initiated by the on Duration Timer, that is, the routine activation. The status is repeated with the trigger activation status.
- restarting the drx-Inactivity Timer is equivalent to extending the time of the active state; after the drx-Inactivity Timer expires, the UE enters the Short DRX state again. After entering several Short DR cycles, you can also enter the Long DR state.

- the UE should be in the routine activation state in the Deep DR state, and is not in the trigger activation state.
- the eNB may configure Deep DRX related parameters for the connected UE by using an RRC reconfiguration message or a system broadcast message. After the eNB configures the Deep DRX related parameters for the UE in the connected state and the UE enters the Deep DR state, as described above, the UE detects that the eNB sends through the common search space in the common search space within the specific activation time, and belongs to the UE.

C-RNTI, S-TMSI, etc.) and corresponding downlink data.
- the Paging message carrying the ID of the UE and the downlink data is detected in the CSS in each TTI when the UE is in the routine activation state and is not in the triggered activation state.
- the above several methods can be used alone or in combination, which further increases the flexibility of scheduling.
- a combination of a and b the UE needs to listen to its own PDCCH command in the CSS, and needs to monitor whether the paging message has information indicating that it receives data; and if a and c are combined, the UE needs to listen to itself in the CSS.
- the PDCCH command needs to monitor whether the paging message has its own data to be received.
- the UE needs to monitor whether the paging message has information indicating that it receives data, and whether the paging message needs to be monitored.
- the data needs to be received; for example, a, b, and c are combined.
- the UE needs to monitor whether the CSS listens to its own PDCCH command, and whether it needs to monitor whether the paging message indicates that it receives data, and whether it needs to monitor whether the paging message is in the paging message.
- the UE needs to try to receive at the same time, but because the base station usually only uses one way to send related indications at the same time, the UE only obtains its own in a certain way. Data or instructions.
- the user equipment when detecting downlink transmission notification information that belongs to the user equipment, performs processing according to the downlink transmission notification information.
- the UE may determine that there is a PDCCH belonging to itself when detecting a PDCCH order scrambled by the C-RNTI of the UE. If the downlink data needs to be received according to the detected PDCCH, the trigger activation state is entered by starting the drx-Inactivity Timer, and the downlink data is received.
- the UE can also leave the Deep DR state when it is learned that downlink data needs to be received. After receiving the downlink data, the UE can also perform corresponding feedback.
- processing described as leaving the Deep DRX state, entering the trigger activation state, receiving downlink data, and performing corresponding feedback.
- One of ordinary skill in the art will appreciate from the description that the departure from the Deep DRX state, as well as feedback, is an optional step.
- the UE may also learn that downlink data needs to be received, leave the Deep DRX state, and enter a trigger activation state by starting a drx-Inactivity Timer.
- the subsequent TTI monitors the possible PDCCH, and receives the downlink data according to the downlink data resource allocation information carried in the PDCCH that is subsequently monitored, and performs corresponding feedback.
- the UE may also learn that downlink data needs to be received, leave the Deep DRX state, and enter a trigger activation state by starting a drx-inactivity timer, and The downlink data is received according to the downlink data resource allocation information carried in the Paging message, and corresponding feedback is performed.
- a time difference between the downlink data and the paging message may be specified, and the time difference may be determined in the standard. It can be configured by the eNB. For example, after receiving the Paging message, the UE receives the corresponding downlink data in the TTI n+4 according to the downlink data resource allocation information carried in the Paging message.
- the UE may also obtain the downlink data in the Paging message when the ID of the UE and the Paging message of the downlink data are detected, leave the Deep DRX state, enter the trigger activation state by starting the drx-Inactivity Timer, and perform the Corresponding feedback.
- the UE receives the Paging message and the downlink data carried by it at time n, and the UE may perform feedback at time n+4, or may feed back at time greater than n+4.
- the UE may be triggered by at least one of the following manners. Random access:
- the UE enters according to the PDCCH command.
- the activation state is triggered, and the random access operation of the UE is performed according to the random access command carried in the PDCCH command.
- the eNB when the eNB needs to schedule the downlink data of the UE, but the uplink of the UE has lost synchronization, the eNB sends the UE to the UE through the CSS in a certain TTI when the UE is in the routine activation state and is not in the triggered activation state.
- the PDCCH command that is scrambled by the C-RNTI of the UE and carries a random access command is used to notify the UE of random access. After the UE learns that the eNB requires the UE to perform random access, the UE performs a random access procedure.
- the Paging message carrying the ID of the UE and the out-of-step adjustment indication identifier is detected in the CSS in a certain TTI, where The out-of-step adjustment indication identifier is used to indicate that downlink data needs to be received, and the UE is currently in an uplink out-of-synchronization state, and the UE performs a random access operation of the UE.
- the eNB when the eNB needs to schedule the downlink data of the UE, but the uplink of the UE has lost synchronization, the eNB is in the Paging message in the CSS of a certain TTI when the UE is in the routine activation state and is not in the triggered activation state.
- Carrying the ID of the UE (such as C-RNTI, S-TMSI, etc.) and the out-of-step adjustment indication identifier, the out-of-synchronization adjustment indication identifier is as described above, indicating that downlink data needs to be received by the UE but the uplink transmission of the UE is out of synchronization. In this way, the UE is notified to perform random access. After the UE learns that the eNB requires the UE to perform random access, the UE performs a random access procedure.
- the two methods for triggering the random access of the UE may be used separately or in combination.
- the UE needs to listen to the random access indication in the PDCCH command scrambled by the C-RNTI of the UE. It is also necessary to monitor the random access indication in the paging message, which further increases the flexibility of the base station scheduling.
- the base station usually only sends the relevant indication in one way at the same time, the UE only obtains the data or indication information belonging to itself in a certain manner.
- step 202 if the UE knows that it is sending only one heartbeat detection packet
- Heart Beat a packet responding to heartbeat detection.
- the UE sends the data, that is, after the activation state is completed, there is no more data to be sent and received for a period of time. At this point, the UE can continue to be in the Deep DRX state without considering leaving the Deep DRX state, thereby further saving power.
- step 202 the UE leaves the Deep DRX state when entering the trigger activation state.
- the UE sends the uplink data, or after the UE sends the empty BSR, or after the UE sends the data and confirms that no other data needs to be transmitted based on the sent packet or other information; or the UE does not request the uplink resource, based on It is confirmed that the transmitted packet or other information does not have uplink data to be transmitted, but the UE receives the UL Grant (uplink grant) of the eNB, and the UE sends no MAC SDU (Media Access Control Service Data Unit).
- the UE may report a message to the eNB requesting to enter the Deep DR state.
- the reported message may be an RRC message or a MAC CE (Media Access Control Control Unit).
- the eNB may notify the UE to directly enter the Deep DRX state if the eNB confirms that it does not need to send downlink data to the UE based on the transmitted packet or other information.
- the UE does not have to go through Short DRX, Long DRX first. Instead, go directly to the Deep DRX state. This allows you to quickly enter a more power-saving mode, resulting in more power-saving effects.
- the notification message may be an RRC message or a MAC CE.
- the eNB may not directly wait for the UE to request to enter the Deep DRX state, but directly notify the UE to directly enter the Deep DRX state.
- the UE may directly enter the Deep DRX state without responding from the eNB.
- the trigger mode in which the UE directly enters the Deep DRX state may be configured by a protocol or may be configured by an eNB.
- the Deep DRX may be replaced by the Long DRX, that is, the UE may request to directly enter the Long DRX when the above specified conditions are met, without first passing the Short DRX; or the eNB may not wait for the UE to request to enter the Long DR.
- the status but directly informs the UE to directly enter the Long DR state, and can also achieve a certain power saving effect.
- the UE may appropriately relax the measurement request when there is no data to be transmitted or received by the UE.
- the UE measures channel conditions during the activation time, for example, the UE may have one of absolute and/or change values of path loss, absolute value of received signal power RSRP and/or change value, RSRQ absolute value and/or change value. Or a plurality of measurements, if the change amount of the measurement result of the UE in the currently specified number of measurement periods is less than the specified threshold value, it indicates that the signal quality of the UE is relatively good and stable, and at this time, the UE has no data to transmit. Then, the UE's requirements for measurement can be relaxed without affecting the mobility of the UE.
- the number of measurement periods, the measurement target, and the threshold value used to estimate the absolute value and/or the change value of the measured quantity may be set by a protocol, or may be configured by an eNB or the like.
- the UE may also determine whether the signal component cell signal quality absolute value is higher than a predetermined threshold value and a signal of a neighboring cell according to whether the change amount of the measurement result in the current specified number of measurement periods is less than a predetermined threshold value. Whether the quality value is lower than one or more of the three judgment conditions of the predetermined threshold value determines whether the signal quality of the UE is relatively good and stable. Therefore, it can be determined whether the UE can enter the Deep DRX state by increasing the judgment of the measurement result.
- the UE may perform the Long DRX after the specified time is reached. It is judged whether the path loss change value in the previously specified measurement period is smaller than the configured gate P ⁇ value. If it is determined that the i3 ⁇ 4 member change value in the previously specified number of measurement periods is less than the configured threshold value, the UE enters the Deep DRX state. No Bay >J, the UE continues to execute Long DRX until the condition that the path loss change value in the previously specified number of measurement periods is less than the configured threshold value.
- the UE when the UE sends the data and requests to directly enter the Deep DRX state, it is determined whether the path loss change value in the predetermined number of measurement periods is less than the configured threshold. If it is determined that the path loss change value in the previously specified number of measurement periods is less than the configured threshold value, the UE directly enters Deep DRX. Otherwise, the UE first enters the Short DRX state, and enters the Long DRX state when there is no data to be transmitted within the specified time after entering the Short DRX state. Enter the Deep DRX state when no data needs to be transmitted within the specified time after entering the Long DR state.
- the UE may determine whether the path loss change value in the previous specified number of measurement periods is less than the configured threshold. If the UE determines that the path loss change value in the specified number of measurement periods is less than the configured threshold value, the UE enters the Deep DRX state. Otherwise, the UE continues to perform Long DRX until the condition that the path loss change value in the previously specified number of measurement periods is less than the configured threshold value is satisfied. Also, when the UE enters the Long DRX state from the Short DRX state, similar processing as described above can also be employed.
- DRX if other conditions are unchanged as described above, when the measured change is less than the corresponding threshold and the absolute value is better than a certain threshold, you can enter Deep DRX. Otherwise, you can enter the Short DRX state, the Long DRX state, and the Deep DRX state in sequence.
- the UE can appropriately relax the measurement request when there is no data to be transmitted or received by the UE.
- the scheme is not limited to use in the scenario of the embodiment, and may be used alone to achieve power saving purposes.
- the measurement period of the UE may be extended. For example, the UE can perform measurements in the IDLE state. Under normal circumstances, when the UE is in the Idle state, the measurement period is a multiple of the DRX period.
- the time that the UE physical layer measures the result to the RRC layer is a multiple of the DRX period. For example, it is 2.56s*5, which is 5 times. Or change the measurement period to longer.
- the user In some scenarios, such as nights, the user is generally in a sleep state, and there are usually few occasions when the service is initiated actively, and the UE does not move. At this time, the measurement requirements are relaxed, the measurement period is extended, and the signal quality of the UE is guaranteed while saving power.
- the UE may relax the measurement request and change the measurement period to the original N times.
- the measurement result may be one or more of an absolute value and/or a change value of the path loss, an absolute value and/or a change value of the received signal power RSRP, an absolute value and/or a change value of the RSRQ.
- the value of N can be set by the protocol or configured by the eNB.
- the UE when the UE performs N times of the measurement period, it is found that the absolute value of the measurement result in the previously specified number of measurement periods does not satisfy the above condition (or another set of conditions is satisfied), and/or the change value of the measurement result is greater than the gate Limit, At this time, the UE can directly shorten the measurement period to the measurement period of the prior art, and the UE can also reduce the multiple value N of the measurement period, and the absolute value of the measurement result does not satisfy the above condition (or meet another set of conditions), and / Or when the change value of the measurement result continuously exceeds the threshold value, the measurement period is gradually shortened until the measurement period is shortened to the measurement cycle of the prior art.
- the UE can extend the periodicity of the periodic location area (TAIL Tracking Area Upate) to N times when the condition is met, so as to reduce the number of times the UE reports the TAU, and reduce the UE. Enter the connected state to send the TAU, and release the power consumption caused by the connection returning to the IDLE state.
- the multiple N value may be set by a protocol or may be configured by an eNB.
- the eNB may perform blind adjustment on the UE without receiving the scheduling request of the UE, and allocate a UL Grant (Uplink Grant) to the UE, and the UE has no data to send, and there is no The data can be sent, so the UE will carry Padding and Buffer Status Report in the sent MAC PDU.
- DRX Uplink Grant
- the UE will start the drx-Inactivity Timer after receiving the UL Grant of the new data transmission, enter the trigger activation state, and then re-execute Short DRX, Long DRX after no data has been received for a period of time. After configuring Deep DRX, the UE will also enter Deep DRX. However, this will lengthen the time that the UE enters Long DR or even Deep DRX, which increases the power consumption of the UE.
- DRX Short DRX, or Long DRX
- the UE enters the Long DRX state when there is no data transmission within a specified number of Short DRX cycles, and the UE enters the Deep DRX state when there is no data transmission within the specified number of Long DRX cycles. If the UE is performing Short DRX, the counter drx Short Cycle Timer that records the condition that the UE enters the Long DRX by the Short DRX (the number of executions of the Short DR period) does not reset the restart, but continues to perform the counting.
- the condition that Short DRX enters Long DRX is that four Short DRX cycles are continuously executed, that is, the UE has no data transmission in four Short DR periods, and the counter is incremented every time the UE performs one DRX cycle.
- the counter of the UE is reset to 0 (assuming an addition count), and during the execution of 4 Short DRX cycles, the UE does not have any Data transmission, the UE enters the Long DRX state.
- the timer of this embodiment is the same as the timer 4 of the prior art, the ⁇ port drx-Inactivity Timer, the HARQ RTT Timer, the Retransmission Timer, and the like.
- the UE After the drx-Inactivity Timer expires, if the counter satisfies the Long DR condition, the UE enters the Long DR state. In Before the drx-Inactivity Timer times out, if the counter satisfies the condition of entering Long DR, the UE directly enters Long DRX after the drx-Inactivity Timer expires.
- the corresponding counter that is, the counter that records the condition that the UE enters Deep DRX by Long DRX (the number of executions of the Long DRX cycle), also does not clear the restart, but continues to count.
- the corresponding figure in this case is shown in Fig. 5. Different from FIG. 4, if the counter satisfies the condition of entering Deep DRX, the UE enters the Deep DR state.
- the UE if the UE is performing Long DRX, the UE continues to execute Long DRX after transmitting the uplink data without actual data, instead of entering the active state first, then executing Short DRX, and then executing Long DRX.
- the specific operation after transmitting the uplink data without actual data is as shown in FIG. 6.
- the timer in this embodiment is the same as the timer in the prior art, such as an Inactivity Timer, a HARQ RTT Timer, a Retransmission Timer, and the like. After the Inactivity Timer expires, the UE continues to execute Long DRX.
- the measurement request of the UE may be appropriately relaxed when it is detected that the UE has no data to transmit or receive.
- the measurement period of the UE may be appropriately extended when it is detected that the UE has no data to transmit or receive.
- the UE may perform DRX and receive uplink scheduling of the eNB, but when no data needs to be sent, the UE continues to perform counting of related counters instead of restarting.
- the above operations can be applied to improve the power saving effect of the UE.

Since the UE does not need to detect its own scheduling command in its own dedicated search space, and the detection frequency of the common search space is very limited, the method can greatly reduce the monitoring behavior of the user equipment by limiting the search time and the search space, thereby enabling Achieve the effect of improving user equipment power saving.
- the user equipment leaves the deep discontinuous reception state, when it is determined that the user equipment does not have data to transmit, acquiring, by the base station, notification information of a depth deep discontinuous reception state sent by the base station, and The notification information entering the deep discontinuous reception state directly enters the deep discontinuous reception state. Therefore, it is not necessary to pass the short discontinuous reception and the long non-continuous reception first, thereby reducing the time when the user equipment is in the active state, and the power saving effect can be further improved.
- the signal quality can be ensured while the UE is saving power. And extending the period of measuring the local cell and/or the neighboring cell by determining that the absolute value of the channel condition measurement result within the specified number of measurement periods obtained satisfies a certain condition and/or the amount of change is less than the set threshold value, or The period of the periodic location area update is extended when the condition is satisfied, and therefore, the number of measurements and/or the number of periodic location area updates are reduced, thereby further improving the power saving effect of the UE.

- the eNB may configure Deep DRX for the UE in the connected state through an RRC reconfiguration message or a system broadcast message. After the eNB configures Deep DRX for the UE in the connected state and the UE enters the Deep DRX, the UE is in the routine activation state and is not in the triggered activation state, in the dedicated search space and the common search space of each transmission time interval. The downlink transmission notification information sent by the eNB is received only in the public search space.
- the base station can also configure other discontinuous reception for the connected user equipment, such as Short DRX, Long DRX, and the like. Knowing that the user equipment performs processing may specifically receive downlink data:
- the eNB sends the PDCCH command scrambled by the C-RNTI of the UE in the CSS of the one or more TTIs to notify the UE to receive the downlink data.
- the eNB sends the Paging message to the UE through the CSS of the one or more TTIs, where the Paging message carries the ID of the UE (such as C-RNTI, S-TMSI, etc.) and the downlink data receiving indication identifier to notify the UE that Subsequent TTIs receive downlink data.
- the Paging message carries the ID of the UE (such as C-RNTI, S-TMSI, etc.) and the downlink data receiving indication identifier to notify the UE that Subsequent TTIs receive downlink data.
- the eNB sends the Paging message to the UE through the CSS of the one or more TTIs, where the Paging message carries the ID of the UE (such as C-RNT1, S-TMSI, etc.) and downlink data resource allocation information, to notify the UE according to the UE.
- the downlink data resource allocation information receives downlink data.
- the eNB sends the Paging message to the UE through the CSS of the one or more TTIs, where the Paging message carries the ID of the UE (such as C-RNTI, S-TMSI, etc.) and downlink data, to notify the UE to receive the Paging message. Downstream data in the middle.
- the eNB can send the PDCCH command with the C-RNTI of the UE in the CSS, and can also indicate the information of the UE receiving the data in the paging message; and if the combination of a and c, the eNB can be in the CSS.

- the information of the data may also carry the data that the UE needs to receive in the paging message; the other various combinations are similar, and will not be described again. It is worth noting that although the above methods can be used in combination, usually the eNB is only in a certain TTI. The data or indication information is sent to the UE in a certain manner.
- the UE may be triggered to perform the processing in at least the following manners, and the processing may be random access:
- the eNB needs to schedule the downlink data of the UE, and when the UE is in the routine activation state and is not in the trigger activation state, the CSS in one or more TTIs is sent with the C- of the UE.
- the RNTI scrambled PDCCH command is used to notify the UE to perform a random access operation.
- the eNB When the eNB needs to schedule the downlink data of the UE, when the eNB needs to schedule the downlink data of the UE, the eNB sends a Paging message to the UE in the one or more CSSs when the UE is in the routine activation state and is not in the triggered activation state.
- the Paging message carries the ID of the UE (such as C-RNTI, S-TMSI, etc.) and the out-of-step adjustment indication identifier to notify the UE to perform a random access operation.
- the out-of-step adjustment indication identifier is used to indicate that downlink data needs to be received, and the UE is currently in an uplink out-of-synchronization state.

- the eNB may use the PDCCH command scrambled by the C-RNTI of the UE to send a random access indication to the UE, or The random access indication is carried in the paging message, which further increases the flexibility of scheduling.
- the base station usually only uses one method to send related indications at the same time. Accordingly, the UE can only obtain its own data or indication information in a certain manner.
- the UE when the UE satisfies certain conditions, it reports a message (RRC message or MAC CE) to the eNB, and requests to enter the Deep DRX state. If the eNB confirms that it does not need to send downlink data to the UE based on the transmitted packet or other information, the eNB may notify the UE to directly enter the Deep DRX state, for example, may send the RRC to cancel. In the manner of the information or the MAC CE, the UE does not need to go through the Short DRX and the Long DRX, but directly enters the Deep DRX state after receiving the notification of the DD to enter the Deep DRX state. This allows you to quickly enter a more power-saving mode, resulting in more power-saving effects. Optionally, the eNB may not directly wait for the UE to enter the Deep DRX state, but directly notify the UE to directly enter the Deep DR state, for example, may notify by sending an RRC message or a MAC CE.

技术领域

背景技术
处于 DRX ( Discontinuous Reception, 非连续接收)状态的 UE ( User Equipment, 用户 设备)意味着该 UE的接收机和发射机只在某些时刻处于工作状态,其它时刻处于关闭状态, 从而达到省电的效果。 在 LTE ( Long Term Evolution, 长期演进) 系统中, DRX既可以应用 在 UE处于空闲态时, 也可以应用在 UE处于连接态时。
当 UE处于连接态时, eNB ( evolved NodeB, 演进基站)可以为 UE配置 DRX, 其中包 括配置 DRX周期和每个周期中 UE进入例行激活期间 (On Duration)的时间点 ( DRX Offset ), 及处于 On Duration的持续时间,即时间长度。其中, UE根据设定的 On Duration及 DRX Offset 周期性地醒来监听属于自己的 PDCCH ( Physical Downlink Control Channel, 物理下行控制 信道)命令。 配置了 DRX的 UE可以处于非激活状态和激活状态。 在 UE处于激活状态 (即 处于激活时间) 时, UE会监听属于自己的 PDCCH命令, 而 UE处于非激活状态时, UE不会 监听属于自己的 PDCCH命令,接收机通常会处于关闭状态,除非此时需要监听寻呼消息或系 统广播消息。
UE在激活状态时接收到要求进行新数据收发的 PDCCH后, UE会延长 UE处于激活状态 的时间, 以便 UE在后续一段时间内能够进行数据收发。
在 LTE系统中, UE处于激活状态监听属于自己的 PDCCH命令时, 需要进行盲检来检测 是否有属于自己的 PDCCH命令, 以确定是否继续处于激活状态。 目前连接态的 UE 居监听 确定是否继续处于激活状态的实现方案, 需要 UE较长时间处于监听状态, 从而会降低 UE 的省电效果。

具体实施方式
下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地
描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施例。 基于本 发明中的实施例, 本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实 施例, 都属于本发明保护的范围。
对于 UE来说, 其所处的激活状态可以包括例行激活状态和触发激活状态。 对于例行 激活状态来说, 通常可以由 UE根据 DRX周期正常进入该状态, 即例行激活状态是 DRX 周期内的一种状态; 对于触发激活状态来说, 则可以由 UE在例行激活状态确定有数据需 要收发时进入该状态。例行激活状态和触发激活状态在时间上可以重叠。比如,配置了 DRX 后, 例行激活状态通常可以根据 on Duration Timer (例行激活期间定时器)进入该状态, 触发激活夫态贝1 J可以才艮据 drx-Inactivity Timer( Discontinuous Reception-Inactivity Timer 连 续接收非激活定时器) 、 drx-Retransmission Timer(Discontinuous Reception- Retransmission Timer,非连续接收重传定时器)或其他条件进入该状态。
eNB可以为 UE配置 Long DRX周期和 Short DRX周期两种 DRX周期,其中 Long DRX 周期可以是 Short DRX周期长度的整数倍。 当 UE被同时配置了两种 DRX周期时, UE没 有数据收发时会先进入 Short DRX状态。 所谓进入 Short DRX状态, 表示 UE会按照 Short DRX的周期、 例行激活时间点及时间长度等 Short DRX的设置参数进行操作。 如果在进入 的事先配置的若干个 Short DRX周期内都没有数据收发, 则开始进入 Long DRX状态。 所 谓进入 Long DR 状态, 表示 UE会按照 Long DR 的周期、 例行激活时间点及时间长度 等 Long DRX的设置参数进行操作。
基于上述配置, 当 UE进入 Short DRX状态时,周期性的醒来监听自己的调度命令 (即 处于例行激活状态) , 如图 1所示, 在 on Duration Timer启动时, 进入该例行激活状态。 如果收到 eNB的新数据传输的调度命令, 则启动 drx-Inactivity Timer, 进入触发激活状态, 如图 1所示, 这时可能还处于 on Duration Timer启动的例行激活状态, 也即例行激活状态 与触发激活状态重复。 如果在该期间再次收到 eNB的新数据传输的调度命令, 则重新启动 drx-Inactivity Timer, 相当于延长处于激活状态的时间; 在 drx-Inactivity Timer超时后, UE 又进入 Short DRX状态。 在进入若干个 Short DR 的周期后, 还可以进入 Long DR 状态。
基于上述分析, 为了能够提高 UE 的省电效果, 本发明实施例提供了一种通信方法, 如图 2所示, 包括:
201、对于配置了深度非连续接收( Deep DRX ) ,且进入 Deep DRX状态的连接态 UE, 该 UE在本 UE处于 Deep DRX状态中的例行激活状态,且不处于触发激活状态时,针对该 时间段中每个传输时间间隔中的专用搜索空间和公共搜索空间, 只在公共搜索空间内检测
属于该 UE的下 4于传输通知信息。
所谓进入 Deep DRX状态, 表示 UE会按照 Deep DRX的周期, 例行激活时间点及时 间长度等设置参数进行周期性地监测相关命令。
该步骤 201主要针对 UE在例行激活状态, 且不处于触发激活状态的情况。 当然, UE 也可以在例行激活状态时, 在公共搜索空间进行检查, 而不考虑是否处于触发激活状态。
其中, Deep DRX可以参考 IDLE (空闲)状态的 UE接收 Paging (寻呼 )消息的 DRX 进行配置, 即, Deep DRX可以拥有与 IDLE状态的 UE相同的 DRX周期, 相同的例行激 活状态的持续时间, 即时间长度, 和 /或相同的进入 On Duration的时间点。
或者,所述 Deep DRX与 Long DRX的参数相同,只是 eNB和 UE在 UE处于 Deep DRX 的例行激活状态, 且不处于触发激活状态时, 在该段时间内的每个传输时间间隔中的操作 与 eNB和 UE在 Long DRX的激活时间的操作不同。 比如, 如前所述, 在 Deep DRX的例 行激活状态, 且不处于触发激活状态时, 针对每个传输时间间隔中的专用搜索空间和公共 搜索空间, 只在公共搜索空间进行监听。 而对于 Long DRX来说, 在所有激活时间内, UE 在公共搜索空间和专用搜索空间都要监听等。
当然, 该连接态的 UE, 还可以配置其他 DRX, 比如, 配置 Short DRX, Long DRX等。 相应地, UE进入 DRX状态时,可以先进入 Short DRX状态,在经过的若干个 Short DRX 周期( Short DRX周期是事先配置的) 内 UE都没有数据需要传输, UE又进入 Long DRX 状态。 而在本发明实施例中, 如果 eNB为 UE配置了 Deep DRX, 且在 UE进入 Long DRX 状态一段时间(可以事先配置)内,该 UE都没有数据需要传输,则该 UE可以进入 Deep DRX 状态。 其中, UE由 Long DRX状态进入 Deep DR 状态时, UE从进入 Long DRX状态到 进入 Deep DRX状态的时间长度可以通过协议进行规定, 也可以由 eNB进行配置。 并且 UE执行 Long DR 的时间值可以设定成一段时间, 也可以设定成 Long DRX周期的倍数。
例如, 当 UE在 Deep DRX的例行激活状态, 且未处于触发激活状态, 收到 eNB传输 给该 UE的、 用于调度 UE新数据的 PDCCH命令后, 会通过启动 drx-Inactivity Timer等方 式,进入触发激活状态, 以接收数据等。 之后如果在一段时间内没有数据传输, 则进入 Short DRX状态, 在进入 Short DRX状态一段时间该 UE没有数据传输时 UE进入 Long DR 状 态,在进入 Long DRX状态一段时间该 UE没有数据传输时 UE进入 Deep DRX状态,具体 如图 3所示。
当然, UE也可以先进入 Long DRX状态, 之后如果没有数据传输, 再进入 Deep DRX 状态; 或者先进入 Short DRX状态, 之后如果没有数据传输, 再进入 Deep DRX状态; 或
者只进入 Deep DRX状态等。
需要说明的是,本发明具体实施方式部分提到的进入 DRX状态,也可以称为执行 DRX 操作, 二者是一个意思。
另外, 不管是如何 UE进入各 DRX状态,对于上述步骤 201来说, UE执行该步骤 201 时, 该 UE应该处于 Deep DR 状态中的例行激活状态, 且不处于触发激活状态。
对于为 UE配置 Deep DRX来说, 举例而言, eNB可以通过 RRC重配置消息或系统广 播消息为连接态的 UE配置 Deep DRX的相关参数。当 eNB为连接态的 UE配置了 Deep DRX 相关参数且 UE进入 Deep DR 状态后, 如前所述, UE在特定的激活时间内、 在公共搜索 空间检测 eNB通过公共搜索空间发送的、 属于该 UE的下行传输通知信息。
其中, UE可以至少通过以下几种方式, 在处于例行激活状态, 且不处于触发激活状态 时, 在每个传输时间间隔 (TTI ) 的专用搜索空间 (DSS, Dedicated Search Space )和公共 搜索空间 (CSS, Common Search Space ) 中, 只在 CSS内检测属于该 UE的下行传输通知 信息:
a、 UE在其处于例行激活状态, 且不处于触发激活状态时, 在每个 ΤΉ的 DSS和 CSS 中, 只在 CSS 内检测以该 UE 的小区无线网络临时标识(C-RNTI, Cell-Radio Network
Temporary Identity )加扰的 PDCCH命令。
例如, eNB需要调度 UE的下行数据时, eNB在 UE处于例行激活状态, 且该 UE不处 于触发激活状态的情况时, 在一个或多个 TTI中的 CSS内向 UE发送以 UE的 C-RNTI加 扰的 PDCCH命令, 以此来通知 UE的下行资源。 UE在其对应的处于例行激活状态, 且不 处于触发激活状态的情况时的每个 TTI中的 CSS内,检测以该 UE的 C-RNTI加扰的 PDCCH 命令。
b、 UE在其处于例行激活状态, 且不处于触发激活状态时, 在每个 ΤΉ的 DSS和 CSS 内中, 只在 CSS内检测携带该 UE的 ID和下行数据接收指示标识的寻呼( Paging ) 消息。
例如, eNB需要调度 UE的下行数据时, eNB在 UE处于例行激活状态, 且不处于触 发激活状态时, 在一个或多个 TTI 的 CSS 内, 在 Paging 消息中携带该 UE 的 ID (如 C-RNTI,S-TMSI等)以及下行数据接收指示标识, 以此来通知 UE接收下行数据。 UE在处 于例行激活状态, 且不处于触发激活状态的情况时的每个 TTI 中的 CSS 内, 检测携带该 UE的 ID以及下行数据接收指示标识的 Paging消息。
c、 UE在其处于例行激活状态, 且不处于触发激活状态时, 在每个 TTI的 DSS和 CSS 中, 只在 CSS内检测携带该 UE的 ID和下行数据资源分配信息的 Paging消息。
例如, eNB需要调度 UE的下行数据时, eNB在 UE处于例行激活状态, 且不处于触 发激活状态的情况时, 在一个或多个 TTI的 CSS内, 在 Paging消息中携带该 UE的 ID (如 C-RNTI,S-TMSI ( System Architecture Evolution-Temporary Mobile Subscriber Identifier, 系统 体系结构演进临时移动用户标识)等)及相应的下行数据资源分配信息, 以此来通知 UE 接收下行数据。 UE在处于例行激活状态, 且不处于触发激活状态的情况时的每个 TTI中的 CSS内, 检测携带该 UE的 ID以及下行数据资源分配信息的 Paging消息。
d、 UE在其处于例行激活状态, 且不处于触发激活状态时, 在每个 TTI的 DSS和 CSS 中, 只在 CSS内检测携带该 UE的 ID和下行数据的 Paging消息。
例如, eNB需要调度 UE的下行数据时, eNB在 UE处于例行激活状态, 且不处于触 发激活状态的情况时, 在一个或多个 ΤΉ中的 CSS内, 在 Paging消息携带 UE的 ID (如 C-RNTI,S-TMSI等)及相应的下行数据。 UE在处于例行激活状态, 且不处于触发激活状态 的情况时的每个 TTI中的 CSS内, 检测携带该 UE的 ID以及下行数据的 Paging消息。
并且, 上述几种方式既可以单独使用, 也可以組合使用, 这样更增加了调度的灵活性。 如 a和 b组合, UE既需要在 CSS监听属于自己的 PDCCH命令, 又需要监听寻呼消息中是 否有指示自己接收数据的信息;再如 a和 c组合, UE既需要在 CSS监听属于自己的 PDCCH 命令, 又需要监听寻呼消息中是否有自己数据需要接收; 再例如, b和 c组合, UE需要监 听寻呼消息中是否有指示自己接收数据的信息, 又需要监听寻呼消息中是否有自己数据需 要接收; 再例如 a, b和 c组合, UE既需要在 CSS监听属于自己的 PDCCH命令, 又需要 监听寻呼消息中是否有指示自己接收数据的信息, 还需要监听寻呼消息中是否有自己数据 需要接收; 其它各种上组合与此类似, 不再赘述。 值得说明的是, 虽然上述方式可以组合 使用, UE需要同时尝试接收, 但因为基站在同一时刻通常只会利用一种方式发送相关的指 示, 所以 UE只会在某一种方式中获得属于自己的数据或指示信息。
202、 所述用户设备在检测到属于所述用户设备的下行传输通知信息时, 则根据该下行 传输通知信息进行处理。
举例而言, UE可以在检测到以该 UE的 C-RNTI加扰的 PDCCH命令时, 确定有属于 自己的 PDCCH。 如果根据检测到的 PDCCH 获知有下行数据需要接收, 则通过启动 drx-Inactivity Timer等方式进入触发激活状态, 并接收下行数据。
当然, 该 UE还可以在获知有下行数据需要接收时, 离开 Deep DR 状态。 该 UE在接 收下行数据后, 还可以进行相应的反馈。
为方便起见, 下面的几种处理方式, 均是直接将 UE在获知有下行数据需要传输时的
处理, 描述为离开 Deep DRX状态, 进入触发激活状态, 接收下行数据, 并进行相应的反 馈。 本领域普通技术人员根据说明书可以知道, 该离开 Deep DRX状态, 以及进行反馈, 只是可选步骤。
或者, UE也可以在检测到携带该 UE的 ID以及下行数据接收指示标识的 Paging消息 时, 获知有下行数据需要接收, 离开 Deep DRX状态, 通过启动 drx-Inactivity Timer等方式 进入触发激活状态, 在后续的 TTI监听可能的 PDCCH, 根据后续监听到的 PDCCH中携带 的下行数据资源分配信息接收下行数据, 并进行相应的反馈。
或者, UE也可以在检测到携带该 UE的 ID以及下行数据资源分配信息的 Paging消息 时, 获知有下行数据需要接收, 离开 Deep DRX状态, 通过启动 drx-Inactivity Timer等方式 进入触发激活状态, 并且, 根据 Paging消息中携带的下行数据资源分配信息来接收下行数 据, 进行相应的反馈。
另外, 由于 UE需要花费时间解析 Paging消息, 来获知是否有下行数据需要该 UE接 收, 因此, 可以规定一个下行数据与 Paging消息的时间差, 如 4个 TTI, 该时间差既可以 在标准中定好,也可以由 eNB进行配置。例如, UE在 TTI n收到 Paging消息后,根据 Paging 消息中携带的下行数据资源分配信息在 TTI n+4接收对应的下行数据。
或者, UE还可以在检测到携带该 UE的 ID以及下行数据的 Paging消息时, 获取该 Paging消息中的下行数据, 离开 Deep DRX状态,通过启动 drx-Inactivity Timer等方式进入 触发激活状态, 并进行相应的反馈。 对于反馈来说, 例如, UE在 n时刻接收 Paging消息 及其携带的下行数据, UE可以在 n+4时刻进行反馈, 也可以在大于 n+4的时刻进行反馈。
上述描述的几种处理, 主要是针对步骤 202中根据下行传输通知信息进行数据接收。 另外, 对于上述步骤 202中根据下行传输通知信息进行的处理, 当 eNB需要调度 UE 的下行数据, 但 UE 的上行已经失去同步时, 具体可以至少通过以下几种方式中的一种或 组合触发 UE的随机接入:
a、 若 UE在其处于例行激活状态, 且不处于触发激活状态的情况时在某个 TTI 中的 CSS内检测到以该 UE的 C-RNTI加扰的 PDCCH命令, 则根据该 PDCCH命令进入触发激 活状态, 并根据该 PDCCH命令中携带的随机接入命令进行 UE的随机接入操作。
例如, 当 eNB需要调度 UE的下行数据, 但 UE的上行已经失去同步时, eNB在 UE 处于例行激活状态, 且不处于触发激活状态的情况时, 通过在某个 TTI中的 CSS向 UE发 送以 UE的 C-RNTI加扰的、 且携带随机接入命令的 PDCCH命令, 以此来通知 UE进行随 机接入。 UE获知 eNB要求该 UE进行随机接入后, UE执行随机接入过程。
b、 若 UE在其处于例行激活状态, 且不处于触发激活状态的情况时, 在某个 TTI中的 CSS内检测到携带该 UE的 ID和失步调整指示标识的 Paging消息,其中,该失步调整指示 标识用于指示有下行数据需要接收, 且该 UE目前处于上行失步状态, 则该 UE进行该 UE 的随机接入操作。
例如, 当 eNB需要调度 UE的下行数据, 但 UE的上行已经失去同步时, eNB在 UE 处于例行激活状态, 且不处于触发激活状态的情况时的某个 TTI的 CSS内,在 Paging消息 中携带该 UE的 ID (如 C-RNTI,S-TMSI等)及失步调整指示标识, 该失步调整指示标识 如前所述, 表示有下行数据需要 UE接收但该 UE的上行传输失去同步, 以此来通知 UE进 行随机接入。 UE获知 eNB要求该 UE进行随机接入后, UE执行随机接入过程。
并且, 上述两种触发 UE 的随机接入的方式可以单独使用, 也可以组合使用, 当组合 使用时, UE既需要监听以该 UE的 C-RNTI加扰的 PDCCH命令中的随机接入指示, 又需 要监听 Paging消息中的随机接入指示, 这样更增加了基站调度的灵活性。 当然, 因为基站 在同一时刻通常只会利用一种方式发送相关的指示, 所以 UE只会在某一种方式中获得属 于自己的数据或指示信息。
另外, 对于上述步骤 202, 如果 UE知道自己发送的只是一个类似于一个心跳检测包
( Heart Beat )和 /或响应心跳检测的包, 该 UE在发送完数据后, 即触发激活状态完成后, 在一段时间内不会再有数据需要发送和接收。 此时 UE可以继续处于 Deep DRX状态, 而 不考虑离开 Deep DRX状态, 从而进一步节约电能。
当然, 还有一种情况, 是在步骤 202中, UE在进入触发激活状态时, 离开 Deep DRX 状态。 这样, 当 UE发送完上行数据后; 或者 UE发送空的 BSR后; 或者 UE发送完数据 后并基于对所发送的包或其它信息确认没有其它数据需要传输时; 或者 UE没有请求上行 资源, 基于对所发送的包或其它信息确认也没有上行数据需要发送, 但 UE收到了 eNB的 UL Grant (上行授权), UE发送不携带任何 MAC SDU ( Media Access Control Service Data Unit,媒体接入控制服务数据单元)的 MAC PDU ( Media Access Control Protocol Data Unit, 媒体接入控制协议数据单元)后, UE可以向 eNB上报消息, 请求进入 Deep DR 状态。 其中, 上报的消息可以是 RRC消息或 MAC CE ( Media Access Control Control Unit, 媒体 接入控制控制单元) 。
eNB在接收到 UE上报的消息后, 如果 eNB基于对所发送的包或其它信息确认其同样 也没有下行数据需要发送给该 UE, 则 eNB可以通知 UE直接进入 Deep DRX状态。 UE在 接收到 eNB发送的进入 Deep DR 状态的通知后, 不必先经过 Short DRX, Long DRX,
而是直接进入 Deep DRX状态。 由此就可以快速进入更省电的模式, 起到更省电的效果。 其中, 通知消息可以是 RRC消息或 MAC CE。
可选的, eNB可以不等到 UE请求进入 Deep DRX状态, 而是直接通知 UE直接进入 Deep DRX状态。或者, UE上 4艮消息请求进入 Deep DRX状态后,可以不需要 eNB的响应, 直接进入 Deep DRX状态。 UE直接进入 Deep DRX状态的触发方式可以由协议进行配置, 也可以由 eNB配置。 类似的, 在本实施例中, 可以将 Deep DRX替换为 Long DRX, 即 UE 在满足上述规定条件时可以请求直接进入 Long DRX, 而不必先经过 Short DRX; 或 eNB 可以不等到 UE请求进入 Long DR 状态, 而是直接通知 UE直接进入 Long DR 状态, 同 样可以达到一定的节电效果。
除上述处理之外, 在 UE没有数据需要发送或接收时, UE可以适当放松测量要求。 UE 在激活时间内会对信道状况进行测量, 例如, UE 可以对路损绝对值和 /或变化值、 接收信 号功率 RSRP绝对值和 /或变化值、 RSRQ绝对值和 /或变化值中的一个或多个进行测量, 如 果 UE在当前规定数量的测量周期内的测量结果的变化量小于规定的门限值, 则说明 UE 的信号质量相对比较好而稳定, 而此时 UE又没有数据需要发送,那么可以放松 UE对测量 的要求而不影响 UE的移动性。 其中, 用来评估测量量的绝对值和 /或变化值的测量周期的 个数、 测量对象、 门限值可以由协议设定, 也可以由 eNB等配置。 另外, UE也可以才艮据 当前规定数量的测量周期内的测量结果的变化量是否小于规定的门限值, 信号服务小区信 号质量绝对值是否高于规定的门限值以及相邻小区的信号质量值是否低于规定的门限值这 三个判断条件中的一个或多个判断条件, 来确定 UE 的信号质量是否相对比较好而稳定。 因此, 可以通过增加对测量结果的判断来确定 UE是否可以进入 Deep DRX状态。
例如, 以路损变化值为测量对象, 如果 eNB为 UE配置了 Deep DRX, 及用来评估测 量变化的测量周期的个数、 门限值, 则 UE可以在执行 Long DRX达到规定的时间后, 判 断之前规定个数的测量周期内的路损变化值是否小于所配置的门 P艮值。 如果判定之前规定 数量的测量周期内的 i¾ 员变化值小于所配置的门限值, 则 UE进入 Deep DRX状态。 否贝 >J, UE继续执行 Long DRX, 直到满足之前规定数量的测量周期内的路损变化值小于所配置的 门限值的条件为止。
或者, 当 UE发送完数据, 请求直接进入 Deep DRX状态时, 判断之前规定数量的测 量周期内的路损变化值是否小于所配置的门限值。 如果判定之前规定数量的测量周期内的 路损变化值小于所配置的门限值, 则 UE直接进入 Deep DRX。否则, UE先进入 Short DRX 状态, 在进入 Short DRX状态后在规定时间内没有数据需要传输时进入 Long DRX状态,
在进入 Long DR 状态后在规定时间内没有数据需要传输时进入 Deep DRX状态。
可选的, UE在进入 Long DRX状态后经过规定的时间仍然没有数据需要传输时, UE 可以判断之前规定数量的测量周期内的路损变化值是否小于所配置的门限值。 如果 UE判 定之前规定数量的测量周期内的路损变化值小于所配置的门限值, 则 UE进入 Deep DRX 状态。 否则, UE继续执行 Long DRX, 直到满足之前规定数量的测量周期内的路损变化值 小于所配置的门限值的条件为止。 并且, UE从 Short DRX状态进入 Long DRX状态时, 也 可以采用上述类似的处理。
可选的, 可以利用测量的绝对值或者利用测量的绝对值和变化值确定是否进入 Deep
DRX, 如其它条件如上所述不变, 当测量的变化量小于对应的门限, 同时绝对值又好于某 个门限时, 可以进入 Deep DRX。 否则, 则可以依次进入 Short DRX状态、 Long DRX状态 及 Deep DRX状态。
类似的,可以将 Deep DR 替换成 Long DRX,在满足测量条件时,直接进入 Long DRX。 在上文中已提到在 UE没有数据需要发送或接收时, UE可以适当放松测量要求。 该方 案不局限于在本实施例的场景中使用, 也可以单独使用, 以达到省电的目的。 另夕卜, 在 UE 没有数据需要发送或接收时,也可以将 UE的测量周期延长。举例而言, UE可以执行 IDLE 状态下的测量。 在正常情况下, UE处于 Idle状态时, 其测量周期是 DRX周期的倍数, 例 如, 当 DRX周期为 2.56s时, UE物理层向 RRC层上 ·ί艮测量结果的时间为 DRX的周期的 倍数, 比如为 2.56s*5 , 即 5倍。 或者将测量周期变为更长。
在某些场景下, 例如夜晚, 用户一般处于睡眠状态, 通常很少有主动发起业务的时候, 且 UE—般不会发生移动。 此时放松测量要求, 延长测量周期, 在 UE的信号质量得到保证 的同时还能节约用电。
基于此, 当 UE在之前的规定数量的测量周期内的测量结果的绝对值满足一定条件和 / 或该测量结果的变化量小于门限值时, UE 可以放松测量要求, 将测量周期变为原来的 N 倍。 其中, 测量结果可以是路损的绝对值和 /或变化值、 接收信号功率 RSRP 的绝对值和 / 或变化值、 RSRQ的绝对值和 /或变化值中的一个或多个。 用来评估测量绝对值和 /或变化值 的测量周期的个数、 测量对象、 门限值以及测量周期的改变倍数 N值可以由协议设定, 也 可以由 eNB配置。 可选的, N值可以有多个, 由小变大, 在测量结果的变化值持续小于门 限值时逐步延长测量周期。
另外, 当 UE执行 N倍的测量周期时, 发现之前规定数量的测量周期内的测量结果的 绝对值不满足上述条件(或满足另外一组条件) , 和 /或该测量结果的变化值大于门限值,
此时 UE可以将测量周期直接缩短成现有技术的测量周期, UE也可以将测量周期的倍数 N 值减少, 在测量结果的绝对值不满足上述条件(或满足另外一组条件) , 和 /或该测量结果 的变化值持续大于门限值时逐步缩短测量周期,直至测量周期缩短到现有技术的测量周期。
与放松测量类似, 对于 IDLE态的 UE, 在满足条件时, 该 UE可以将周期性位置区更 新的周期( TAIL Tracking Area Upate )延长为原来的 N倍, 以减少 UE上报 TAU的次数, 减少 UE进入连接态发送 TAU, 并释放连接返回 IDLE态造成的耗电。 其中, 该倍数 N值 可以由协议设定, 也可以由 eNB配置。
另外, eNB基于时延考虑, 可能会在没有收到 UE的调度请求的情况下对 UE进行盲 调, 为 UE分配 UL Grant ( Uplink Grant, 上行授权) , 此时 UE没有数据需要发送, 也没 有数据可以发送, 因此 UE会在发送的 MAC PDU中携带 Padding (填充)及空 BSR ( Buffer Status Report, 緩存状态报告) 。 如果配置了 DRX, UE会在收到新数据传输的 UL Grant 后,启动 drx-Inactivity Timer,进入触发激活状态,然后在一段时间没有数据收到后重新执行 Short DRX, Long DRX。 在配置了 Deep DRX后, UE还会进入 Deep DRX。 但这样会延 长 UE进入 Long DR 甚至 Deep DRX的时间, 使 UE的耗电增加。
针对此种情况, 当 UE在执行 DRX ( Short DRX, 或 Long DRX )时, 如果接收到 eNB 的上行调度, 但又没有数据需要发送, 则 UE会继续执行相关计数器的计数, 而不是重启。
举例而言, 假定 UE在经过的规定数量的 Short DRX周期内没有数据传输时进入 Long DRX状态, UE在经过的规定数量的 Long DRX周期内没有数据传输时进入 Deep DRX状 态。 如果 UE正在执行 Short DRX, 则记录 UE由 Short DRX进入 Long DRX的条件( Short DR 周期的执行数量) 的计数器 drx Short Cycle Timer不复位重启, 而是继续执行计数。 例如, 规定 Short DRX进入 Long DRX的条件是连续执行 4个 Short DRX周期, 即在 4个 Short DR 周期内 UE都没有数据传输, UE每执行一个 DRX周期, 该计数器会加一。 如 图 4所示, 现有技术中 UE在接收到 eNB的上行调度后, 该计数器的计数结果会重新置 0 (假设采用加法计数) , 在执行 4个 Short DRX周期内, UE—直都没有数据传输, UE进 入 Long DRX状态。 而在本实施例中, 在 UE执行到第二个 Short DR 周期时, 如果接收 到 eNB的上行调度, 但又没有数据需要发送, 则该计数器会继续执行计数, 此时计数器的 计数结果为 2。 在计数器的计数结果为 4 (减法计数的话计数结果为 0 ) , 且 UE—直都没 有数据传输时, UE进入 Long DR 状态。 图 4中, 本实施例的定时器与现有技术的定时器 4目同, ^口 drx-Inactivity Timer, HARQ RTT Timer, Retransmission Timer等。在 drx-Inactivity Timer超时之后, 如果计数器满足进入 Long DR 条件, 则 UE进入 Long DR 状态。 在
drx-Inactivity Timer 超时之前, 如果计数器满足进入 Long DR 的条件, 则 UE 在 drx-Inactivity Timer超时后直接进入 Long DRX。
类似地, 如果 UE正在执行 Long DRX, 则相应的计数器, 即记录 UE由 Long DRX进 入 Deep DRX的条件( Long DRX周期的执行数量)的计数器, 也是不清零重启, 而是继续 执行计数。 该情况对应的附图为图 5。 与图 4不同的是, 如果计数器满足进入 Deep DRX 的条件, 则 UE会进入 Deep DR 状态。
或者, 如果 UE正在执行 Long DRX, 则 UE在发送完没有实际数据的上行数据后, 继 续执行 Long DRX, 而不是先进入激活态, 再执行 Short DRX, 再执行 Long DRX。 现有技 术和本实施例在执行 Long DRX时, 发送完没有实际数据的上行数据后的具体操作如图 6 所示。图 6中,本实施例的定时器与现有技术的定时器相同,如 Inactivity Timer, HARQ RTT Timer, Retransmission Timer等。在 Inactivity Timer超时之后, UE仍然继续执行 Long DRX。
在本实施例中,可以在检测到 UE没有数据需要发送或接收时,适当放松 UE的测量要 求。 或者, 也可以在检测到 UE没有数据需要发送或接收时, 将 UE的测量周期适当延长。 或者, 还可以在 UE执行 DRX, 接收到 eNB的上行调度, 但又没有数据需要发送时, UE 继续执行相关计数器的计数, 而不是重启。 另外, 即使在 UE未配置 Deep DRX的情况下, 也可以应用上述各项操作, 以达到提高 UE省电的效果。
本实施例提供的通信方法, 当连接态的用户设备配置且执行深度非连续接收, 且所述 用户设备处于例行激活状态, 并且不处于触发激活状态时, 在每个传输时间间隔中, 只在 公共搜索空间内检测属于所述用户设备的下行传输通知信息, 并在检测到属于所述用户设 备的下行传输通知信息时, 根据所述下行传输通知信息进行处理。 由于 UE不需要在自己 的专用搜索空间检测属于自己的调度命令, 而公共搜索空间的检测次数十分有限, 因此, 该方法通过限定搜索时间以及搜索空间, 可以大幅减少用户设备的监听行为, 从而能够达 到提高用户设备省电的效果。
并且, 通过在所述用户设备离开深度非连续接收状态后, 在确定所述用户设备没有数 据需要传输时, 获取所述基站发送的进入深度非连续接收状态的通知信息, 并 #_据所述进 入深度非连续接收状态的通知信息, 直接进入深度非连续接收状态。 因此, 不必先经过短 非连续接收和长非连续接收, 减少了用户设备处于激活状态的时间, 可以进一步提高省电 效果。
并且, 通过在获取的信道状况测量结果的绝对值满足一定条件和 /或变化量小于设置的 门限值时, 进入深度连续接收状态, 从而可以在 UE省电的同时保证信号质量。
并且, 通过在确定获取的规定数量的测量周期内的信道状况测量结果绝对值满足一定 条件和 /或变化量小于设置的门限值时, 延长测量本小区和 /或相邻小区的周期, 或者, 在满 足条件时延长周期性位置区更新的周期, 因此,减少测量次数和 /或周期性位置区更新次数, 从而进一步提高 UE的省电效果。
另外, 通过在用户设备处于短非连续接收状态或长非连续接收状态时, 在接收基站发 送的上行调度后, 计算由短非连续接收周期进入长非连续接收周期或由长非连续接收周期 进入深度非连续接收的数量的计数器继续进行计数, 因此, 缩短了用户设备进入长非连续 接收状态或深度非连续接收状态的时间, 减少了用户设备处于激活状态的时间, 从而进一 步提高 UE的省电效果。
与上述方法相对应地, 本发明实施例还提供了一种通信方法, 包括:
基站为连接态的用户设备配置深度非连续接收; 基站在所述用户设备处于深度非连续 接收状态中的例行激活状态, 且不处于触发激活状态时, 在一个或多个传输时间间隔的专 用搜索空间和公共搜索空间中,只在公共搜索空间发送所述用户设备的下行传输通知信息, 以通知所述用户设备才 M居所述传输通知信息进行处理。
例如, eNB可以通过 RRC重配置消息或系统广播消息为连接态的 UE配置 Deep DRX。 当 eNB为连接态的 UE配置好 Deep DRX且 UE进入 Deep DRX后, UE在处于例行激活状 态, 且不处于触发激活状态时, 在每个传输时间间隔的专用搜索空间和公共搜索空间中, 只在公共搜索空间接收该 eNB发送的下行传输通知信息。
基站还可以为连接态的用户设备配置其他的非连续接收, 比如 Short DRX, Long DRX 等。 知用户设备进行处理, 具体可以是接收下行数据:
a、 eNB通过在一个或多个 TTI的 CSS发送以 UE的 C-RNTI加扰的 PDCCH命令, 以 通知该 UE接收下行数据。
b、 eNB通过在一个或多个 TTI的 CSS发送给 UE的 Paging消息, 该 Paging消息携带 该 UE的 ID (如 C-RNTI,S- TMSI等)和下行数据接收指示标识,以通知该 UE在后续的 TTI 接收下行数据。
c、 eNB通过在一个或多个 TTI的 CSS发送给 UE的 Paging消息, 该 Paging消息携带 该 UE的 ID (如 C-RNT1,S-TMSI等)和下行数据资源分配信息, 以通知该 UE根据下行数 据资源分配信息接收下行数据。
d、 eNB通过在一个或多个 TTI的 CSS发送给 UE的 Paging消息, 该 Paging消息携带 该 UE的 ID (如 C-RNTI,S-TMSI等)和下行数据, 以通知该 UE接收该 Paging消息中的下 行数据。
并且, 上述几种方式既可以单独使用, 也可以组合使用, 这样更增加了调度的灵活性。 如 a和 b组合, eNB既可以在 CSS发送以 UE的 C- RNTI加掩的 PDCCH命令, 又可以在 寻呼消息中指示 UE接收数据的信息; 再如 a和 c组合, eNB既可以在 CSS发送以 UE的 C-RNTI加掩的 PDCCH命令, 又可以在寻呼消息中携带 UE需要接收的数据; 再例如, b 和 c组合, eNB既可以在寻呼消息中指示 UE接收数据的信息, 又可以在寻呼消息中携带 UE需要接收的数据; 再例如 a, b和 c组合, eNB既可以在 CSS发送以 UE的 C-RNTI加 掩的 PDCCH命令,可以在寻呼消息中指示 UE接收数据的信息,还可以在寻呼消息中携带 UE需要接收的数据; 其它各种上组合与此类似, 不再赘述, 值得说明的是, 虽然上述方式 可以组合使用, 但通常 eNB在某 TTI只会以某一种方式中向 UE发送数据或指示信息。
另外, 当 eNB需要调度 UE的下行数据, 但 UE的上行已经失去同步时, 可以至少通 过以下几种方式触发 UE进行处理, 该处理具体可以是随机接入:
a、 在 UE上行失去同步, eNB需要调度 UE的下行数据时, eNB在 UE处于例行激活 状态, 且不处于触发激活状态时, 在一个或多个 TTI中的 CSS发送以该 UE的 C-RNTI加 扰的 PDCCH命令, 以通知 UE进行随机接入操作。
b、 在 UE上行失去同步, eNB需要调度 UE的下行数据时, eNB在 UE处于例行激活 状态, 且不处于触发激活状态时, 在一个或多个 ΤΉ中的 CSS向 UE发送 Paging消息, 该 Paging消息携带该 UE的 ID (如 C-RNTI,S-TMSI等)和失步调整指示标识, 以通知 UE进 行随机接入操作。 其中, 该失步调整指示标识用于指示有下行数据需要接收, 且该 UE 目 前处于上行失步状态。
上述两种触发 UE的随机接入的方式可以单独使用, 也可以组合使用, 当组合使用时, eNB既可以使用以 UE的 C-RNTI加扰的 PDCCH命令向 UE发送随机接入指示, 又可以在 Paging消息中携带随机接入指示, 这样更增加了调度的灵活性。 当然, 基站在同一时刻通 常只会利用一种方式发送相关的指示,相应地, UE也只会通过某一种方式获得属于自己的 数据或指示信息。
另外, 当 UE在满足一定条件, 向 eNB上报消息( RRC消息或 MAC CE ), 请求进入 Deep DRX状态时。 如果 eNB基于对所发送的包或其它信息确认其同样也没有下行数据需 要发送给该 UE, 则 eNB可以通知 UE直接进入 Deep DRX状态, 例如可以以发送 RRC消
息或 MAC CE的方式通知, UE在接收到 eNB发送的进入 Deep DRX状态的通知后, 不必 先经过 Short DRX、 Long DRX, 而是直接进入 Deep DRX状态。 由此就可以快速进入更 省电的模式, 起到更省电的效果。 可选的, eNB可以不等到 UE请求进入 Deep DRX状态, 而是直接通知 UE直接进入 Deep DR 状态,例如可以以发送 RRC消息或 MAC CE的方式 通知。
本实施例提供的基站, 当连接态的用户设备配置且执行深度非连续接收, 且所述用户 设备处于例行激活状态, 且不处于触发激活状态时, 在每个传输时间间隔中, 只在公共搜 索空间内发送属于所述用户设备的下行传输通知信息, 使得 UE只需要在处于例行激活状 态, 且不处于触发激活状态时, 在公共搜索空间内检测属于所述用户设备的下行传输通知 信息。 由于 UE不需要在自己的专用搜索空间检测属于自己的调度命令, 而公共搜索空间 的检测次数十分有限, 因此, 该方法通过限定搜索时间以及搜索空间, 可以大幅减少用户 设备的监听行为, 从而能够达到提高用户设备省电的效果。
并且, 通过在所述用户设备离开深度非连续接收状态后, 在确定所述用户设备没有数 据需要传输时, 所述基站发送进入深度非连续接收状态的通知信息, 使得 UE可以根据所 述进入深度非连续接收状态的通知信息, 直接进入深度非连续接收状态。 因此, 不必先经 过短非连续接收和长非连续接收, 减少了用户设备处于激活状态的时间, 可以进一步提高 省电效果。
