摘要： Apparatus and methods are provided for sidelink resource allocation in a NR network. In one novel aspect, the RX UE based sensing and resource allocation are provided. The RX UE based sensing work independently or jointly with the TX UE based sensing and resource allocation. In one embodiment, the RX UE performs sensing based on SCI decoding of the other UEs' SCI and measures RSRP. The RX UE determines whether the reserved resources are acceptable based on sensing results derived from the measured RSRP results and a threshold. The RX UE indicates acceptability of the reserved resources to the TX UE. In one embodiment, the acceptability information carried with one additional bit multiplexing with an ACK/NACK (A/N) bit. In another embodiment, the acceptability information is not multiplexed with the A/N bit. In yet another embodiment, the acceptability information is transmitted on a feedback resource indicated in the received SCI.

摘要： For SL resource allocation, the Rx UE based sensing and resource allocation mechanism can be applied to improve the reliability and reduce the overall latency, which can work independently or jointly with Tx UE based sensing and resource allocation mechanism. Rx UE performs sensing based on SCI decoding of the other UEs' SCI and measure RSRP on the DMRS of the PSCCH and/or the associated PSCCH/PSSCH. If the reserved resource (s) indicated in SCI from the peer Tx UE are same or overlapping with the sensing resources, the Rx UE will determine whether the reserved resources are acceptable based on sensing results derived from the measured RSRP results and a threshold. Rx UE will indicate acceptability of the reserved resources to Tx UE. The threshold for comparison with RSRP results may be determined based on the function of the priority level indicated in SCI by the other UEs and the priority level indicated in SCI from the peer Tx UE.

摘要： For SL resource allocation, the Rx UE assisted resource allocation mechanism can be applied to improve the reliability and reduce the overall latency for SL communication, which can work independently or jointly with Tx UE based sensing and resource allocation mechanism. Rx UE can be triggered to send the feedback information upon reception of the SCI and/or data from the Tx UE. The feedback information can carry Rx UE's resource sensing information, CSI info, observed Doppler/delay/moving speed related information and MIMO related feedback information to assist the resource/MCS/MIMO/DMRS pattern selection at Tx UE. It is desirable for Rx UE to feedback such assistance information (just) before the reserved resources by Tx UE to be transmitted. So the Tx UE can take into account the feedback information to assist resource re-selection and/or resource utilization.

摘要： This disclosure relates generally to wireless communications, and, more particularly, to methods and apparatus about resource allocation for SL. For SL resource allocation, the Rx UE can transmit the assistance information to assist Tx UE's resource selection. For the reserved resource indicated in SCI from the peer Tx UE, the Rx UE can indicate the resources are not preferred via the signaling, e.g., one bit in the physical SL feedback channel (PSFCH) to the peer Tx UE if the reserved resources are not preferred based on the sensing results at Rx UE. On the other hand, the Rx UE can transmit at least SCI carrying resource reservation information from the peer Tx UE at least to the potential interfering UEs for resource collision avoidance if the reserved resources is preferred/acceptable based on the sensing results at Rx UE.

It is desirable for Rx UE to feedback such assistance information (just) before the reserved resources by Tx UE to be transmitted. So the Tx UE can take into account the feedback information to assist resource re-selection and/or resource utilization. Rx-UE can get the reserved Tx resource information from SCI of Tx UE and determine the feedback timing based on the instant for transmission of the reserved Tx resources by considering the additional time for Tx UE to process the assistance information. Meanwhile, the Rx-UE should feedback the latest assistance information, i.e., updated feedback information based on the transmission timing of the assistance information.

摘要： A method pertaining tochannelstate information (CSI) reporting for multiple transmission/reception-points (multi-TRP) in next-generation mobile communications involves a user equipment (UE) generating a CSI report for multiple TRPs in communications with the UE. Additionally, the method also involves the UE transmitting the CSI report to one or more of the multiple TRPs using one or multiple CSI reporting resources.
