Description

Carrier Aggregation Implementation Method, Carrier Availability Detection Method and Device

technical field

The present invention relates to the technical field of wireless communication, in particular to a method for realizing carrier aggregation, a method and a device for detecting carrier availability.

Background technique

The existing Long Term Evolution (LTE, Long Term Evolution) system can only work in the authorized frequency band assigned to the cellular mobile communication system defined by the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) standardization organization, but with the mobile With the rapid development of Internet services, the traffic volume is increasing, and the existing licensed frequency bands are gradually unable to meet the frequency requirements of the LTE system.

The existing LTE system can only work in the licensed frequency band (licensed, the frequency is allocated to fixed users, exclusive) allocated to the cellular mobile communication system. With the shortage of frequency resources, the licensed frequency band will not be able to meet the future business frequency requirements . my country has allocated 2400-2483.5MHz, 5150-5250MHz, 5250-5350MHz and 5725-5850MHz for Wireless Local Area Networks (WLAN, Wireless Local Area Networks), a total of 408.5MHz of license-free frequency bands (Unlicensed, no fixed frequency users, as long as they meet The technical requirements of the frequency band can be used without reporting to the management agency), and the new license-free frequency band of 5475-5725MHz may be opened in the future. The license-free frequency band is expected to become an important supplement to the license-free frequency band, but the existing LTE system cannot be used in the license-free frequency band.

Currently, a hypothetical solution for realizing the use of the license-free frequency band in the LTE system is a solution of carrier aggregation using a carrier of the licensed frequency band and a carrier of the license-free frequency band.

In my country, the United States, South Korea, Japan, Europe and other countries, some license-free frequency bands have special coexistence requirements for protecting other services. For example, in my country’s 5250-5350MHz and 5475-5725MHz license-free frequency bands, terminals need to have dynamic frequencies Select (DFS, Dynamic frequency selection) function to detect interference from radar systems and avoid working on the same carrier with these radar systems in order to ensure the performance requirements of radar systems. If the above-mentioned unlicensed frequency bands are used for communication in the LTE system, the relevant requirements for protecting the radar system must also be met.

On the other hand, when using the license-free frequency band for communication in the LTE system, if other network systems (such as radar systems, or network systems provided by other network operators) are also using the same license-free frequency band, the LTE The system uses this license-free frequency band for communication, causing serious interference and degrading system performance.

Detailed ways

In order to provide an implementation plan for avoiding adverse effects on the performance of other network systems when using license-free frequency bands for carrier aggregation, and to improve the performance of the network using license-free frequency bands for carrier aggregation communications, embodiments of the present invention provide a method using The implementation method and device for carrier aggregation of license-free frequency bands. In order to provide an implementation scheme for detecting the carrier availability of license-free frequency bands, the embodiment of the present invention also provides a method and device for detecting the availability of license-free frequency bands. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Example 1:

Embodiment 1 of the present invention provides a carrier aggregation implementation method using an unlicensed frequency band, which is applied to the network side, as shown in Figure 1, including:

Step 101, the network side receives capability information reported by the terminal indicating whether the terminal supports carrier aggregation in licensed frequency bands and license-free frequency bands.

Step 102: When the capability information indicates that the terminal supports carrier aggregation of licensed frequency bands and license-free frequency bands, determine the currently available carriers in the license-free frequency bands supported by the terminal.

Wherein, the available carrier may be a carrier not used by other networks.

Step 103, for the terminal, configure the carrier in the licensed frequency band as the primary carrier, and configure the available carrier as the secondary carrier.

Step 104: Perform carrier aggregation using the primary carrier and the secondary carrier to communicate with the terminal.

Correspondingly, Embodiment 1 of the present invention also provides a method for reporting capability information, which is applied to the terminal side, as shown in FIG. 2 , including:

In step 201, the terminal reports capability information of whether the terminal supports carrier aggregation in licensed frequency bands and license-free frequency bands to the network side.

Wherein, the capability information can be used by the network side to perform carrier aggregation configuration for the available carrier that the terminal uses the license-free frequency band supported by the terminal and is currently available according to the capability information, where the available carrier is not used by other networks carrier.

Further, it can also include:

Step 202: After carrier aggregation is configured on the network side, perform carrier aggregation using a primary carrier and a secondary carrier to communicate with the network side. The primary carrier is a carrier in the licensed frequency band, and the secondary carrier is the available carrier.

In the carrier aggregation implementation method using the license-free frequency band shown in Figures 1-2 of the present invention, further, the terminal can also report the number of the license-free frequency band supported by the terminal to the network side, and the terminal supports aggregation in the license-free frequency band The number of carriers, the maximum aggregate bandwidth supported by the terminal in the unlicensed frequency band, and one or any combination of information of the terminal's use of the unlicensed frequency band for carrier aggregation, and the network side correspondingly based on the received information to configure carrier aggregation.

The method provided by the present invention will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

FIG. 3 is a flowchart of a method for implementing carrier aggregation using an unlicensed frequency band provided in Embodiment 1 of the present invention, which specifically includes the following processing steps:

In step 301, the terminal reports capability information of whether the terminal supports carrier aggregation in licensed frequency bands and license-free frequency bands to the network side.

The capability information may be pre-configured on the terminal when the terminal leaves the factory, and the terminal may directly obtain and report it.

Step 302. When the terminal supports carrier aggregation of licensed frequency bands and license-free frequency bands, it may further report one or any combination of the following information to the network side:

The number of the license-free frequency band supported by the terminal;

The number of carriers that the terminal supports aggregation in the license-free frequency band. Specifically, the number of carriers may include the number of uplink carriers and/or the number of downlink carriers;

The maximum aggregate bandwidth supported by the terminal in the license-free frequency band;

Information about how the terminal uses license-free frequency bands for carrier aggregation.

Among them, the terminal uses the unlicensed frequency band for carrier aggregation, which can include the following four methods:

The first method: use the auxiliary carrier in the license-free frequency band as a frequency division duplexing (FDD, Frequency Division Duplexing) method.

The second type: use the auxiliary carrier of the license-free frequency band as time division duplexing (TDD, Time Division Duplexing).

The third method: use the auxiliary carrier in the license-free frequency band as a pure downlink mode of frequency division duplexing.

The fourth type: use the auxiliary carrier in the license-free frequency band as a time-division duplex pure downlink mode.

Various information in this step can be carried and reported in one message, or can be carried and reported in different messages respectively.

Step 303: After receiving the capability information reported by the terminal, when the capability information indicates that the terminal supports carrier aggregation between the licensed frequency band and the license-free frequency band, the network side determines the currently available carrier in the license-free frequency band, wherein the available carrier is an unused carrier. Carriers used by other networks.

The currently available available carriers may be available carriers in the license-free frequency band in the current scheduling period.

In the embodiment of the present invention, whether each carrier in each license-free frequency band is available can be determined according to which carriers in those license-free frequency bands are pre-configured in each scheduling cycle. Flexible configuration for usage.

Whether each carrier in each license-free frequency band is available can also be determined by periodically dynamically monitoring the signal power strength of other network signals carried by the carrier in the license-free frequency band. The strength is large, for example, greater than a first preset power threshold When , it means that the carrier is being used by other networks and is currently unavailable; otherwise, it means that the carrier is not being used by other networks and is currently available.

Further, when it is determined that the carrier is available, the signal power of the network signal carried by the carrier may be further compared with a second preset power threshold, and if it is greater than, it is determined that the carrier is a restricted available carrier, and if it is not greater than the second preset power threshold , determine that the carrier is a fully available carrier, so that the fully available carrier can be preferentially selected to perform carrier aggregation in the network subsequently.

Step 304, the network side determines available carriers in the unlicensed frequency band supported by the terminal and currently available.

Among them, the license-free frequency band supported by the terminal may be a pre-configured default license-free frequency band supported by the terminal, or when the terminal reports the number of the license-free frequency band it supports, the license-free frequency band indicated by the number may be determined as the terminal supported unlicensed frequency band.

Step 305, the network side performs carrier aggregation configuration for the terminal using the licensed frequency band and the license-free frequency band, including: configuring the carrier in the licensed frequency band as the main carrier, and configuring the license-free frequency band supported by the terminal determined in step 304 above and currently in the The available carrier in the available state is the secondary carrier.

When available carriers are divided into restricted available carriers and fully available carriers, it is preferable to select fully available carriers for carrier aggregation so as to obtain better communication performance.

In the embodiment of the present invention, there may be multiple available carriers in the unlicensed frequency band supported by the terminal and currently available. Therefore, multiple available carriers may be configured as auxiliary carriers.

Further, when receiving the number of carriers that the terminal supports aggregation in the unlicensed frequency band reported by the terminal, available carriers that do not exceed the number of carriers may be configured as secondary carriers.

Furthermore, when the number of carriers reported by the terminal is received as the number of uplink carriers and/or the number of downlink carriers, correspondingly, the available carriers that do not exceed the number of uplink carriers are configured as uplink secondary carriers, and the configuration does not exceed the number of uplink secondary carriers. The available carrier for the number of downlink carriers is the downlink auxiliary carrier.

In this step, when the maximum aggregated bandwidth supported by the terminal in the license-free frequency band reported by the terminal is also received, it is also necessary to refer to the maximum aggregated bandwidth when performing carrier aggregation configuration, that is, the carrier in the licensed frequency band is configured as the main carrier. And after the available carrier is configured as the secondary carrier, it needs to be satisfied that the carrier aggregation bandwidth does not exceed the maximum aggregation bandwidth.

Step 306: After the carrier aggregation configuration is completed on the network side, communication is performed between the network side and the terminal using the carrier aggregation of the primary carrier and the secondary carrier.

The specific communication process can be performed in the same manner as the carrier aggregation communication in the prior art, and will not be described in detail here.

Further, when receiving the use mode information reported by the terminal that the terminal uses the license-free frequency band to perform carrier aggregation, correspondingly, the network side and the terminal use the main carrier and the auxiliary carrier according to the use mode indicated by the use mode information. Aggregation for communication.

In the embodiment of the present invention, at least one of the following specific communication procedures may be adopted:

The network side can use the main carrier to send downlink control information to the terminal;

The network side can use the main carrier to send scheduling information for the license-free frequency band to the terminal;

The terminal uses the main carrier to report channel quality feedback information to the network side;

The terminal uses the main carrier to report acknowledgment/negative acknowledgment (ACK/NACK, Acknowledgment/Negative Acknowledgment) information to the network side.

Using the above method provided in Embodiment 1 of the present invention, since the carrier in the license-free frequency band as the secondary carrier is an available carrier when performing carrier aggregation, the available carrier is used for carrier aggregation, which avoids adverse effects on other network system performance In addition, it also avoids the interference caused by other network systems using the available carrier to the communication of the network, thereby improving the performance of carrier aggregation communication in the network using the license-free frequency band.

And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Example 4:

Embodiment 4 of the present invention provides a method for detecting the availability of license-free frequency bands, which is applied to the network side, as shown in Figure 6, including:

Step 601, the network side detects the signal power of other network signals carried by the target carrier in the unlicensed frequency band.

Step 602: When the signal power is greater than the first power threshold, determine that the target carrier is an unavailable carrier; when the signal power is not greater than the first power threshold, determine that the target carrier is an available carrier.

Further, when the signal power is not greater than the first power threshold, the relationship between the signal power of the local network signal carried by the target carrier and the second power threshold may also be compared, and when the signal power of the local network signal carried by the target carrier When the power is greater than the second power threshold, it is determined that the target carrier is a restricted available carrier; when the signal power of the network signal carried by the target carrier is not greater than the second power threshold, it is determined that the target carrier is a fully available carrier. Compared with restricted available carriers, fully available carriers are more conducive to carrier aggregation with carriers in licensed frequency bands.

Wherein, the first power threshold and the second power threshold can be flexibly determined according to the actual situation of the target carrier, for example, the first power threshold is -72dBm/MHz, and the second power threshold is -55dBm/MHz.

Further, in Embodiment 4 of the present invention, the availability detection of the carrier in the license-free frequency band can be triggered periodically, for example, the detection period is monitored, and when the detection period arrives, the detection of other network signals carried by the target carrier in the license-free frequency band is triggered signal power.

Events can also be used to trigger the availability detection of carriers in the unlicensed frequency band. For example, when the signal quality of the network signal carried by the target carrier in the unlicensed frequency band does not meet the preset signal quality conditions, trigger the detection of other networks carried by the target carrier. The signal power of the signal.

Wherein, determining that the signal quality of the network signal carried by the target carrier does not meet the preset signal quality conditions may specifically include:

Determine that the channel quality feedback information CQI of the target carrier in the network is less than the preset CQI threshold; or

Determine that the block error rate BLER of the network signal carried by the target carrier is greater than the preset BLER threshold; or

Embodiment 6:

Embodiment 6 of the present invention provides a method for detecting the availability of license-free frequency bands, which is applied to the network side, as shown in Figure 8, including:

Step 801, the network side sends detection configuration information for performing availability detection on a target carrier in an unlicensed frequency band to the terminal.

Step 802, receiving the detection result of the availability detection of the target carrier based on the detection configuration information sent by the terminal.

Correspondingly, Embodiment 6 of the present invention also provides a method for detecting the availability of an unlicensed frequency band, which is applied to the terminal side, as shown in FIG. 9 , including:

Step 901, the terminal receives the detection configuration information for performing availability detection on the target carrier in the unlicensed frequency band sent by the network side.

Step 902: Perform availability detection on the target carrier based on the detection configuration information.

Step 903, sending the detection result to the network side.

In the above methods shown in Figures 8-9, the detection configuration information sent by the network side to the terminal may include at least one of the following information:

detection cycle;

Detection time period information, which may specifically be the detection time length and detection starting position;

The number of the license-exempt frequency band;

The frequency of the carrier in the unlicensed band.

Correspondingly, the terminal may detect the target carrier in the unlicensed frequency band according to the above various detection configuration information.

In the above methods shown in Figures 8-9, the detection results sent by the terminal to the network side can be in the following two forms:

The first form: The detection result sent by the terminal to the network side is the signal power of other network signals carried by the terminal to detect the target carrier. Correspondingly, the network side can determine the availability of the target carrier based on the received signal power. The method provided in Embodiment 5 above will not be described in detail here.

The second form: the terminal determines the detection result of whether the target carrier is available, and sends the detection result to the network side as available information indicating that the target carrier is an available carrier, or as unavailable information indicating that the target carrier is an unavailable carrier, The network side can directly determine whether the target carrier is available according to the received detection result.

The method for detecting the carrier availability in the unlicensed frequency band provided by Embodiment 6 of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 10 is a flow chart of a method for detecting the availability of an unlicensed frequency band carrier provided by Embodiment 6 of the present invention, which specifically includes the following processing steps:

Step 1001, the terminal sends to the network side capability information indicating that the terminal supports availability detection of carriers in the unlicensed frequency band.

The capability information may be pre-configured on the terminal when the terminal leaves the factory, and the terminal may directly acquire and send it.

Step 1002: After receiving the capability information sent by the terminal, the network side sends to the terminal detection configuration information for performing availability detection on the target carrier in the license-exempt frequency band.

The sent detection configuration information may include at least one of the following information:

detection cycle;

Detection time period information, which may specifically be the detection time length and detection starting position;

The number of the license-exempt frequency band;

The frequency of the carrier in the unlicensed band.

For detection configuration information that is not included in the detection configuration information and needs to be used when the terminal performs detection, it may be pre-configured on the terminal for use by the terminal when performing detection.

In this step, the network side may send the detection configuration information to the terminal in a broadcast manner or in a dedicated signaling manner.

In the embodiment of the present invention, when the default terminal supports availability detection of carriers in the unlicensed frequency band, the execution of the above step 1001 may be cancelled.

Step 1003, after receiving the detection configuration information sent by the network side, the terminal performs availability detection on the target carrier in the license-free frequency band based on the detection configuration information.

Among them, the license-free frequency bands to be detected can be all license-free frequency bands, pre-configured license-free frequency bands, or license-free frequency bands indicated by the number of the license-free frequency band in the detection configuration information, that is, the number indicates Availability detection of the target carrier in the unlicensed frequency band.

The target carrier that needs to be detected can be all carriers in the license-free frequency band that need to be detected, or it can be a pre-configured carrier, or it can be a carrier in the license-free frequency band indicated by the frequency of the carrier in the detection configuration information, that is, the frequency The indicated target carrier performs availability detection.

In this step, the availability detection of the carrier in the unlicensed frequency band may be triggered periodically, for example, the detection period is monitored, and when the detection period arrives, the availability detection of the target carrier in the unlicensed frequency band is triggered. Wherein, the detection period may be pre-configured, or may be included in the received detection configuration information.

Periodic detection is adopted, and the detection result of this time is valid within this period, that is, the carrier availability result detected during this period remains unchanged before the arrival of the next detection period.

Events can also be used to trigger the availability detection of unlicensed frequency band carriers. For example, when the signal quality of the network signal carried by the target carrier in the unlicensed frequency band does not meet the preset signal quality conditions, trigger the availability of the target carrier in the unlicensed frequency band. detection.

Wherein, determining that the signal quality of the network signal carried by the target carrier does not meet the preset signal quality conditions may specifically include:

Determine that the channel quality feedback information CQI of the target carrier in the network is less than the preset CQI threshold; or

Determine that the block error rate BLER of the network signal carried by the target carrier is greater than the preset BLER threshold; or

It is determined that the number of NACK feedbacks of the target carrier in the local network within a preset time period is greater than a preset NACK threshold.

It is also possible to use a combination of periodic triggering and event triggering.

In this step, the terminal can also perform availability detection on the unlicensed frequency band carrier within the detection time period. The detection time period can be pre-configured, or it can be the detection indicated by the detection time period information included in the received detection configuration information. A time period, that is, within the detection time period represented by the detection time period information, the availability detection is performed on the target carrier.

Wherein, the detection time period information may specifically be the detection time length and the detection start position, that is, the detection time period may be represented by the detection time length and the detection start position, and the detection time period may be one or more subframes, or is one or more OFDM symbols.

Further, when the auxiliary carrier adopts the frequency division duplex FDD mode, the detection time period indicated by the detection period information may be a subframe configured as a multicast/multicast single frequency network MBSFN of the auxiliary carrier, and a subframe configured as an MBSFN The frame may be all subframes of the secondary carrier, or may be part of subframes;

The detection time period indicated by the detection time period information may also be an uncalled uplink subframe of the secondary carrier, and the uncalled uplink subframe may be all uplink subframes of the secondary carrier, or may be part of uplink subframes.

In this step, the detection result obtained by the terminal may be in the above-mentioned first form, or in the above-mentioned second form.

Taking the detection result obtained in the above second form as an example, the specific detection process for the terminal to perform availability detection of the target carrier in the license-free frequency band based on the detection configuration information is described in detail, which may include the following steps 1003-1 to 1003-2 :

Step 1003-1, the terminal detects the signal power of other network signals carried by the target carrier in the license-free frequency band.

Step 1003-2. When the signal power is greater than the first power threshold, determine that the target carrier is an unavailable carrier; when the signal power is not greater than the first power threshold, determine that the target carrier is an available carrier.

Further, when the signal power is not greater than the first power threshold, the relationship between the signal power of the network signal carried by the target carrier and the second power threshold may also be compared, and when the signal power is greater than the second power threshold , determining that the target carrier is a restricted available carrier; when the signal power of the network signal carried by the target carrier is not greater than the second power threshold, determining that the target carrier is a fully available carrier. Compared with restricted available carriers, fully available carriers are more conducive to carrier aggregation with carriers in licensed frequency bands.

Wherein, the first power threshold and the second power threshold can be flexibly determined according to the actual situation of the target carrier, for example, the first power threshold is -72dBm/MHz, and the second power threshold is -55dBm/MHz.

Step 1004, the terminal sends the detection result to the network side.

Step 1005, the network side may receive multiple detection results sent by multiple terminals for the availability detection of the same target carrier in the unlicensed frequency band, and may determine the availability of the same target carrier according to each of the detection results (including according to the above-mentioned one form of detection results, and directly obtained according to the above-mentioned second form of detection results), at this time, the network side can jointly consider the multiple received detection results to determine the final availability of the same target carrier Test results. For example, it can be done as follows:

When the received multiple detection results sent by multiple terminals for the availability detection of the same target carrier in the license-free frequency band all indicate that the same target carrier is an available carrier, determine that the same target carrier is an available carrier;

When there is a detection result indicating that the same target carrier is an unavailable carrier among the multiple detection results received by multiple terminals for the availability detection of the same target carrier in the license-free frequency band, determine that the same target carrier is an unavailable carrier .

Step 1006, further, when the received detection results of the availability detection of the same target carrier in the unlicensed frequency band sent by multiple terminals all indicate that the same target carrier is an available carrier, that is, the final detection result is the same target carrier When the carrier is an available carrier, the network side may also determine the final available time of the same target carrier based on the multiple available times of the same target carrier determined by the multiple detection results, for example, the following manner may be used:

When the multiple available times of the same target carrier determined for the multiple detection results are the same, determine the same available time as the final available time of the same target carrier;

When the multiple available times of the same target carrier determined for the multiple detection results are different, the intersection time of the multiple available times is determined as the final available time of the same target carrier.

Using the above method for detecting the availability of license-free frequency band carriers provided in Embodiment 6 of the present invention, the availability detection of license-free frequency band carriers is realized, thereby providing a reference basis for usable carriers for carrier aggregation using license-free frequency bands, thereby ensuring the use of licenses Various requirements for frequency bands and unlicensed frequency bands for carrier aggregation, including performance guarantee requirements for other networks using unlicensed frequency bands, and traffic performance requirements for this network.
