Description
METHODS, TERMINAL DEVICE AND NETWORK NODE FOR UPLINK TRANSMISSION
Technical Field
[0001] Embodiments of the discîosure generally relate to wireless communication, and, more particularly, to methods, a terminai device and a network node for uplink transmission.
Background
[0002] This section introduces aspects that may facilitate better understanding of the présent disclosure. Accord in gly, the statements of this section are to be read in this ligne and are not to be understood as admissions about what is in the prior art or what is not in the prior art.
[0003] Next génération Systems are expected to support a wide range of use cases with varying requirements ranging from fully mobile devices to stationary Internet of things (loT) or fixed wireless broadband devices. The traffic pattern associated with many use cases is expected to consist of short or long bursts of data traffic with varying length of waiting period in between (here called inactive State). In new radio (NR), both license assisted access and standatone unlicensed operation are to be supported in 3rd génération partnership project (3GPP).
[0004] In order to tackle with the ever increasing data demanding, NR is considered both licensed and unlicensed spectrum. Compared to the long term évolution (LTE) licensed assisted access (LAA), NR-based access to unlicensed spectrum (NR-U) also needs to support dual connectivity (DC) and standalone scénarios, where the media access contre! (MAC) procedures including random access channel (RACH) and scheduling procedure on unlicensed spectrum are subject to the listen before talk (LBT) failures, while there is no such restriction in LTE LAA, since there is licensed spectrum in LAA scénario so the RACH and scheduling related signaling can be transmitted on the licensed spectrum instead of unlicensed spectrum.
[0005] For discovery référénce signal (DRS) transmission such as primary synchronization signal (PSS)/secondary synchronization signal (SSS), physical broadcast channel (PBCH), channel State information réference signai (CSi-RS), control channel transmission such as physical uplink control channel (PUCCH)/physicat downlink control channel (PDCCH), physical data chance! such as physical uplink shared channel (PUSCH)/physical downlink shared channel (PDSCH), and uplink sounding reference signal such as SRS transmission, channel sensing should be applied to détermine the channel availability before t'ne physical signal is transmitted using the channel.
[0006] The radio resource management (RRM) procedures in NR-U would be generaîly rather similar as in LAA, since NR-U is aiming to reuse LAA/enhanced LAA (eLAA)/further enhanced LAA (feLAA) technologies as much as possible to handle the coexistence between NR-U and other legacy radio access technologies (RATs). RRM measurements and report comprising spécial configuration procedure with respect the channel sensing and channel availabilîty.
[0007] Hence, channel access/selection for LAA was one of important aspects for coexistence with other RATs such as Wi-Fi. For instance, LAA has aimed to use carriers that are congested with Wi-Fi.
[0008] In licensed spectrum, user equipment (UE) measures Reference Signal Received Power (RSRP), and Reference Signa! Received Quality (RSRQ) of the downlink radio channel (e.g. synchronization signal (SS) and PBCH biock simply referred to as SS B, CSI-RS), and provides the measurement reports to its serving evolved node B (eNB)/next génération node B (g NB). However, they don’t reflect the interférence strength on the carrier. Another metric Received Signal Strength Indicator (RSSI) can serve for such purpose. At the eNB/gNB side, it is possible to dérivé RSSI based on the received RSRP and RSRQ reports. However, this requires that they must be available. Due to the LBT failure, some reports in terms of RSRP or RSRP may be blocked (can be either due to that the reference signal transmission (DRS) is blocked in the downlink or the measurement report is blocked in the uplink). Hence, the measurements in terms of RSSI are very useful. The RSSI measurements together with the time information concerning when and how long time that UEs hâve made the measurements can assist the gNB/eNB to detect the hidden node. Additionally, the gNB/eNB can measure the load situation of the carrier which is useful for the network to prioritize some channels for load balance and channel access failure avoidance purposes,
[0009] LTE LAA has defined to support measurements of averaged RSSI and channel occupancy for measurement reports. The channel occupancy is defined as percentage of time that RSSI is measured above a configured threshold. For this purpose, a RSSI measurement timing configuration (RMTC) includes a measurement duration (e.g. 1-5 ms) and a period between measurements (e.g. {40, 80, 160, 320, 640} ms).

Detailed Description
[00107] For the purpose of explanation, details are set forth in the following description in order to provide a thorough understanding of the embodiments disclosed. It is apparent, however, to those skilled in the art that the embodiments may be implemented without 35 these spécifie details or with an équivalent arrangement.
[00108] For a node (e.g., NR-U gNB/UE, LTE-LAA eNB/UE, or Wi-Fi access point (AP)/statron (STA)) to be ailowed to transmit in uniicensed spectrum (e.g., 5GHz band), it typically needs to perform a clear channei assessment (CCA). This procedure typically includes sensing the medium to be idîe for a number of time intervals. Sensing the medium to be idle can be done in different ways, e.g. using energy détection, preamble détection or using Virtual carrier sensing. The iatter implies that the node reads control information from other transmitting nodes informing when a transmission ends. After sensing the medium to be idle, the node is typically ailowed to transmit for a certain amount of time, sometimes referred to as transmission opportunity (TXOP). The length of the TXOP dépends on régulation and type of CCA that has been performed, but typically ranges from 1ms to 10ms. This duration is often referred to as Channei Occupancy Time (COT).
[00109] in Wi-Fi, feedback of data réception acknowledgements (ACKs) is transmitted withouf performing clear channei assessment. Preceding feedback transmission, a small time duration (called SIFS) is introduced between the data transmission and the corresponding feedback which does not include aciual sensing of the channei. In 802.11, the SIFS period (16 μ s for 5GHz orthogonal frequency division multiplexing (OFDM) PHYs) is defined as:
aSIFSTime = aRxPHYDelay + aMACProcessingDelay + aRxTxTumaroundTime, where aRxPHYDelay defines the duration needed by the physical (PHY) layer to deliver a packet to the MAC layer, aMACProcessingDelay defines the duration that the MAC layer needs to trigger the PHY layer transmitting a responsê, and aRxTxTumaroundTime defines the duration needed to tum the radio from réception into transmission mode. Therefore, the SIFS duration is used to accommodate for the hardware delay to switch the direction from réception to transmission.
[00110] It is anticipated that for NR in uniicensed bands (NR-U), a similar gap to accommodate for the radio tumaround time will be ailowed. For example, this will enable the transmission of PUCCH canying UCI feedback as well as PUSCH carrying data and possible UCI within the same transmit opportunity (TXOP) acquired by the initiating g NB without the UE performing clear channei assessment before PUSCH/PUCCH transmission as long as the gap between downlink (DL) and uplink (UL) transmission is less than or equai to 16 ps. Operation in this manner is typically called “COT sharing.” An example on COT sharing is illustrated in FIG 1. It shows TXOP both with and without
COT sharing where CCA is performed by the initiating node (gNB). For the case of COT sharing, the gap between DL and UL transmission rs less than 16 μ s. F! G. 2 illustrâtes an example on a UE COT sharing with the DL transmission. For the case of COT sharing, the gap between UL and DL transmission is less than 16us.
[00111] Listen-before-talk (LBT) is designed for unlicensed spectrum co-existence with other RATs. In this mechanism, a radio device appties a clear channel assessment (CCA) check (i.e, channel sensing) before any transmission. The transmitter involves energy détection (ED) over a time period compared to a certain energy détection threshold (ED threshold) in order to détermine if a channel is idle. In case the channel is determined to 10 be occupied, the transmitter perfomns a random back-off within a contention window before next CCA attempt. în order to protect the ACK transmissions, the transmitter must defer a period after each busy CCA slot prior to resuming back-off. As soon as the transmitter has grasped access to a channel, the transmitter is only allowed to perform transmission up to a maximum time duration (namely, the maximum channel occupancy 15 time (MCOT)). For QoS différentiation, a channel access priority based on the service type has been defined. For exampîe, there are four LBT priority classes defined for différentiation of channel access priorities between services using contention window size (CWS) and MCOT duration.
[00112] As described in 3GPP technical report (TR) 38.889 V16.0.0, the channel 20 access schemes for NR-based access for unlicensed spectrum can be classified into the following categories. Category 1 is Immédiate transmission after a short switching gap. This is used for a transminer to immediatêly transmît after a UL/DL switching gap inside a COT. The switching gap from réception to transmission is to accommodate the transceiver tumaround time and is no longer than 16ps. Category 2 is LBT without 25 random back-off. The duration of time that the channel is sensed to be idle before the transmitting entity transmits is deterministic,
[00113] Category 3 is LBT with random back-off with a contention window of fixed size. The LBT procedure has the following procedure as one of its components. The transmitting entity draws a random number N within a contention window. The size of the 30 contention window is specified by the minimum and maximum value of N. The size of the contention window is fixed. The random number N is used in the LBT procedure to détermine the duration of time that the channel is sensed to be idle before the transmitting entity transmits on the channel.
[00114] Category 4 is LBT with random back-off with a contention window of variable size. The LBT procedure has the foliowing as one of its components. The transmitting entity draws a random nurnber N within a contention window. The size of contention window is specified by the minimum and maximum value of N. The transmitting entity can 5 vary the size of the contention window when drawing the random nurnber N. The random nurnber N is used in the LBT procedure to détermine the duration of time that the channel is sensed to be idle before the transmitting entity transmits on the channel. For different transmissions in a COT and different channels/signals to be transmitted, different categories of channel access schemes can be used.
[00115] There may be some parameters in UCI; HARQ ID, NDI, RV, COT sharing information, and some additional information may also be included. Foliowing parameters may be included in configured grani (CG)-UCI: details on COT sharing information such as LBT Priority class value (channel access agenda), Remaining COT duration and Signaling indicator for enabling/disabling COT sharing; UE-ID; CRC; PUSCH start and end point/slot; Resource configuration index; Sterling position of a transmitted PUSCH; MCS/TBS, if enhancement on link adaptation is supported; CBGTI, if CBG based retransmission on configured grant resources is supported.
[00116] Based on above, a UE would include above information in a CG-UC! for a transmission with a configured grant. However, it may occur that both PUCCH-UCI and 20 CG-UCI are triggered in the same time. The former can be triggered by either of below conditions: 1) HAQR A/N for réception of DL data; 2) CSl report; 3) scheduling request (SR) due to arrivai of new data. In case the UE accommodâtes both UCIs on the same PUSCH, there may be too much control overhead so that the data transmission may be negatively impacted. Therefore, it would be advantageous to fix the issues when both
UCIs are triggered and being overlapped in time.
[00117] The présent dîsclosure proposes an improved solution for uplink transmission. The solution may be applied to a wireless communication system including a terminal device and a network node such as a base station or any other node with similar functionality. The terminal device can communîcate through a radio access communication link with the base station, The base station can provide radio access communication links to terminal devices that are within its communication service cell. Note that the communications may be performed between the terminai device and the base station according to any suitable communication standards and protocols. The terminal device may also be referred to as, for example, device, access terminal, user equipment (UE), mobile station, mobile unit, subscriber station, or the like. It may refer to any end device that can access a wireless communication network and reçoive services therefrom. By way of example and not limitation, the terminal device may include a portable computer, an image capture terminal device such as a digital caméra, a gaming 5 terminal device, a music storage and playback appliance, a mobile phone, a cellular phone, a smart phone, a tablet, a wearable device, a personal digital assistant (PDA), or the like.
[00118] In an Internet of things (loT) scénario, a terminal device may represeni a machine or other device that perforons monitoring and/or measurements, and transmits io the results of such monitoring and/or measurements to another terminai device and/or a network equipment. in this case, the terminal device may be a machine-to-machine (M2M) device, which may, in a 3GPP context, be referred to as a machine-type communication (MTC) device. Particular examples of such machines or devices may include sensors, metering devices such as power meters, industrial machineries, bikes, 15 vehicfes, or home or personal appliances, e.g. refrigerators, télévisions, personal wearables such as watches, and so on.
[00119] Now, severai embodiments will be described to expiain the improved solution for uplink transmission. The basic idea is to introduce a collision handling mechanism for handling collision between the associated CG-UCl (or plus the corresponding PUSCH 20 transmission) and PUCCH-UCl. Note that the collision between the two UCls can also be defined as the collision between the transmission for the PUSCH canying the first UCI and the transmission of the second UCI carried by PUCCH. Because the gNB relies on the first UCI carried in the PUSCH using a configured grant to décodé the PUSCH, the first UCI and the PUSCH are multiplexed in the same PUSCH transmission.
[00120] Although these embodiments will be described in the context of NR-U, the principle of the disclosure is also applicable to other unlicensed operation scénarios (e.g. LTE LAA/eLAA/feLAA/MuLteFire) and licensed operation scénarios where, for example, one UCI for a configured grant transmission and the other UCI for a dynamically scheduled DL transmission are triggered and being overiapped in the time,
[00121] As a first embodiment, a collision handling mechanism is introduced. The UE may détermine a priority level for each UCI in terms of at least one of conditions:
1) The priority of LCHs/logioal channel groups (LCGs) that are associated with the UCI;
2) Latency budget or transmission reliability requirement of the data 35 associated with the UCI;
3) a predefined priority between CG-UCi (and the corresponding PUSCH using configured grant) and PUCCH UC!;
4) The information content in the UCI.
[00122] For the first aspect, the LCH priority levels (such as 5QI in 5G network, or QCI in 4G network) is associated with the transmitted data for which the UCI is generated, i.e., the data activity of those LCHs has triggered the UCI. If the UCI transmitted using configured grant has a higher priority than the data transmitted in DL using PDSCH, the CG-UCI may be be prioritized by the UE. Otherwise, the PUCCH UCI may be prioritized over the CG-UCI. As another option, the relative priorities between UL and DL LCHs can be predefined or preconfigured.
[00123] For the second aspect, the UE may consider what is the latency budget left for the data in order to fulfill certain latency target. if the upiink data is close to deiay budget, the PUSCH transmission using configured grant and the associated CG-UCI may be prioritized than PUCCH UCI for DL HARQ transmission. Otherwise, PUCCH UCI for DL HARQ transmission may be prioritized than the PUSCH using configured grant and the associated CG-UCI. As a simple option, the UE may détermine the priority of the PUSCH and CG-UCI based on the queuing delay of the data to be transmitted. If the queuing delay is larger than a preconfigured threshold, the PUSCH and the associated CG-UCI may be prioritized than PUCCH UC! for DL HARQ transmission. The UE may also consider what is the requirement of transmission reliabiiity for the associated data. The priority of the CG-UCI may also be determined based on the corresponding PUSCH transmission priority.
[00124] For the thîrd aspect, in one examp le, CG-UCI and the corresponding PUSCH may be preconfigured with higher priority than PUCCH-UC1, because the UL grant has to be skipped if the CG-UCI is not transmitted. In another exemple, PUCCH-UCI may be preconfigured with higher priority than PUSCH using configured grant and the associated CG-UCI, when PUCCH-UCI contains HARQ A/N at the last chance (e.g., the UE has received a DC! carrying a maximum K2 value). Without receiving such information, there can be an residual HARQ transmission faifure for the data block.
[00125] The priority level may be considered for handling the collision between CG-UCI and PUCCH-UCI.
[00126] As a second embodiment, based on the determined priority, the UE may be configured to take at least one of below actions, for example:
1) Option 1: transmit PUCCH-UCI in another serving cell if PUCCH resources are avaiiable in this serving ce!!, wherein this serving cell may belong to a same or different PUCCH cell group with the cell that has triggered the PUCCH-UCI.
2) Option 2: Move PUCCH-UCl to any other serving cell, if there is no any other cell configured with available PUCCH resource for transmission of this PUCCH-UCl. The UE may trigger a random access (RA) on that cell. The UCI may be transmitted in a RA message. The gNB may configure PUCCH resource for the UE in that cell upon réception of RA, In this case, the UCI may be transmitted on obtained PUCCH resource after the RA procedure.
3) Option 3: skip or delay transmission for the UCI with lower priority. In this way, UCI information with higher priority is served first given limited space on PUSCH transmission. In case CG-UCI is skipped, meaning that the configured grant is skipped, PUCCH-UCl is transmitted on PUCCH channei. That is, when the CG-UCI is lower priortized than the second UCI and not transmitted, the configured grant for the PUSCH comprising the first UCi is skipped.
4) Option 4: enabling simultaneous transmission for PUCCH and PUSCH using configured grant for the cell.
5) Option 5: mergtng both UCIs into a new UCI, and transmitting it on the PUSCH using configured grant. During merging procedure, some low priority information fields may be dropped due to limited room for UCI. The merged content format may be configured by the gNB. For instance, the CSI can be lower prioritized than the HARQ process ID, RV1 and UE ID.
The configuration of any one or more of the above options may be signaled by the gNB to a UE via a RRC message, System information, a MAC CE, or L1/L2 control signaling.
[00127] As a third embodiment, the PUCCH UCI is discarded when there is not HARQ NACK carried and only PUSCH using configured grant and the associated CG-UCI is transmitted. Otherwise, the PUCCH UCI is transmitted and the UL grant is skipped (i.e. PUSCH using configured grant and the associated CG-UC! are not transmitted).
[00128] As a fourth embodiment, the relative priority between PUSCH using configured grant and the PUCCH UCI can be preconfigured by frie network. When the UE has been configured with multiple PUCCH resources and/or CG grants of different CG configurations in a ceîl/BWP, the relative priority can be configured per PUCCH resource and SR configuration pair. In an example, the network can include the configuration in SR configuration, cell configuration or cell group configuration using dedicated RRC signaling. In another example, the network can configure the relative priority using MAC CE.
[00129] As a fifth embodiment, the PUCCH UCI may be carried as a sub MAC PDU in the MAC PDU mapped into the PUSCH using configured grant. For one instance, a new MAC CE is defined to carry the PUCCH UCI. The sub MAC PDU can be in the front position of the MAC PDU so that the gNB can décodé the PUCCH early,
[00130] As a sixth embodiment, the fonction of collision handling may be configured per cell/carrier/BWP/channei/subband. Different handling options may be configured for different serving celi/camer/BWP/channeï/subband.
[00131] Hereinafter, the solution will be further described with reference to FIGs. 3-13, 5 FIG. 3 is a flowchart illustrating a method implemented at a terminal device according to an embodiment of the disclosure. At block 302, the terminai device détermines priority information about a first UCI associated with a PUSCH transmission using a configured grant and a second UCI carried by a PUCCH. The PUSCH transmission carrying the first UCI and the PUCCH transmission carrying the second UCI may be overlapped in time.
The priority information may comprise a first priority for the first UCI and a second priority for the second UCI. Alternatively, the priority information may comprise a relative priority between the first and second UCIs.
[00132] For example, the following options may be used to détermine the priority information. As the first option, the priority information may be determined based at least 15 on a priority of at least one logicai channel associated with each of the first and second
UCIs. The priority of the at least one logicai channel associated with each of the first and second UCIs may be determined based on one of: a priority of data of the at least one logicai channel for which each of the first and second UCIs is generated; and a predefined relative priority between at least one uplink logicai channel associated with the 20 first UCI and at least one downlink logicai channel associated with the second UCI.
[00133] As the second option, the priority information may be determined based at least on a latency budget of data associated with each of the first and second UCIs. For example, the determined priority information may indicate that the first UCI is prioritized over the second UCI in response to one or more of foliowings: remaining latency budget 25 of uplink data associated with the first UC! is smailer than a first predetermined threshold;
and a queuing delay of uplink data associated with the first UCI is larger than a second predetermined threshold.
[00134] As the third option, the priority information may be determined based at least on a transmission reliability requirement of data associated with each of the first and second 30 UCIs. As the fourth option, the priority information may be determined based at least on a predefined or preconfigured relative priority between the first and second UCIs. For examplë, the first UCI may be predefined or preconfigured to hâve a higher priority than the second UCI which does not carry HARQ NACK. As a fifth option, the first priority for the first UCI may be determined based on the corresponding PUSCH transmission 35 priority. Note that any one of the above first to fifth options may be used atone or in combination.
[00135] Optionally, the terminal device may be configured with multiple PUCCH resources and/or configured grants of multiple configured scheduling configurations. In this case, corresponding priority information may be preconfigured in the temninai device for each pair of a PUCCH resource and a configured scheduling configuration.
[00136] At block 304, the terminal device transmits at least part of the first and second UCIs based on the determined priority information, in this way, the collision between the two UCIs can be handled properly. The at least part of the first and second UCIs may be one of: the first UCI; the second UCI; the first UCI and the second UCI; the first UCI and part of the second UCI which are merged as one UCI; the second UCI and part of the first UCI which are merged as one UCI; and part of the first UCI and pari of the second UCI which are merged as one UCI.
[00137] If the priority information indicates that the first UCI has a higher priority than the second UCI, the transmission at block 304 may comprise one or more of: transmitting the second UCI in a PUCCH cell which is different than current PUCCH cell; transmitting the second UCI through random access in a cell which is different than current cell triggering the second UCI; transmitting only the first UCI; transmitting the first and second UCIs in this order with a delay between the two transmissions; and transmitting, as one merged UCI, at teast part of the first UCI and at least part of the second UCI. For example, one or more fields in the first and/or second UCI with lower priorities may be removed from the one merged UCI.
[00138] On the other hand, if the priority information indicates that the second UC! has a higher priority than the first UCI, the transmission at block 304 may comprise one or more of: transmitting only the second UCI; transmitting the second and first UCIs in this order with a delay between the two transmissions; simultaneously transmitting the second UCI and PUSCH using the configured grant; and transmitting, as one merged UCI, at least part of the first UCI and at least part of the second UCI. Note that when the first UCI is lower prioritized than the second UCI and not transmitted, the configured grant for the PUSCH comprising the first UCI may be skipped.
[00139] In a case that the second UCI is transmitted, the second UCI may be canried as a sub MAC PDU in an MAC PDU mapped into a PUSCH using the configured grant. The sub MAC PDU may be disposed in a front position of the MAC PDU. In this way, the base station can décodé the PUCCH early. For example, the sub MAC PDU may be a (e.g. newly defined) MAC CE.
[00140] Optionally, the determining at block 302 and th© transmitting at block 304 may be performed in a same way or differentiy for different cell/carrier/bandwidth part/channel/subband.
[00141] FIG. 4 is a flowchart iliustrating a method implemented at a network node accordîng to an embodiment of the disclosure. The network node may be a base station or any other node with similar functionality. At block 402, the network node détermines priority information about a first UCI associated with a PUSCH transmission using a configured grant and a second UCI carried by a PUCCH, and/or at least one configuration for transmitting at least part of the first and second UCIs. At block 404, the network node transmits the priority information and/or the at least one configuration.
[00142] The priority information may comprise at least one relative priority between the first and second UCIs. Alternative^, the priority information may comprise at least one group of a first priority for the first UCI and a second priority for the second UCI. Optionally, the number of the at least one relative priority or the at least one group may be more than one. Each of the more than one relative priorities or the more than one groups may correspond to a pair of a PUCCH resource and a configured scheduling configuration.
[00143] Optionally, the priority information may comprise relative priorities between different fields contained in the first and second UCIs. Optionally, the priority information and/or the at least one configuration may be the same or different for different cell/carrier/bandwidth part/channel/subband.
[00144] In case the priority information indicates that the first UCI has a higher priority than the second UCI, the at least one configuration for transmitting at least part of the first and second UCIs may comprise one or more of: transmitting the second UCI in a PUCCH cell which is different than current PUCCH cell; transmitting the second UCI through random access în a cell which is different than current cell triggering the second UCï; transmitting only the first UCI; transmitting the first and second UCIs in this order with a delay between the two transmissions; and transmitting, as one merged UCI, at least part of the first UCI and at least part of the second UCI.
[00145] On the other hand, in case the priority information indicates that the second UCI has a higher priority than the first UCI, the at least one configuration for transmitting at least part of the first and second UCIs may comprise one or more of: transmitting only the second UCI; transmitting the second and first UCIs in this order with a delay between the two transmissions; simultaneously transmitting the second UCI and PUSCH using the configured grant; and transmitting, as one merged UCI, at least part of the first UCI and ai least part of the second UCI. !t should be also noted that two blocks shown in succession in the figures may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved.
