摘要： A method by which a first device performs wireless communication and a device for supporting same are provided. The method may comprise the steps of: acquiring a configuration for partial sensing-based resource selection, the partial sensing including periodic-based partial sensing (PBPS) or contiguous partial sensing (CPS); receiving, from a second device, inter-UE coordination (IUC) information including information related to a preferred resource set; acquiring sidelink (SL) data; and selecting, on the basis that the partial sensing is skipped for power saving, a transmission resource for the SL data from among resources belonging to the preferred resource set included in the IUC information.

摘要： Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a sidelink control indicator (SCI) from a second UE and selects resources and directions for communication. The SCI may include one or more resources and corresponding directions reserved by the second UE. The first UE may use the resources and directions indicated in the received SCI to select available resources with which to reserve forward direction transmissions, reverse direction transmissions, or both. For example, the first UE may avoid reserving resources and directions corresponding to the resources and directions indicated in the received SCI, or may reserve such resources despite receiving the SCI, such as if the received SCI has a relatively low reference signal received power (RSRP). The first UE may transmit an SCI indicating resources reserved by the first UE and associated directionalities.

摘要： A wireless transmit/receive unit (WTRU) may receive one or more physical downlink shared channel (PDSCH) transmissions and each PDSCH transmission may be associated with downlink control information (DCI) and a group of PDSCH transmissions. Further, the WTRU may determine a first group or a second group based on an indication received in DCI associated with at least one of the PDSCH transmissions. Then, the WTRU may generate hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for data received in one or more PDSCH transmissions associated with the determined group. Moreover, the WTRU may transmit the HARQ-ACK feedback. In an example, the DCI which includes the indication may schedule a plurality of PDSCH transmissions included in the determined group. In another example, the DCI which includes the indication may further include a first codepoint mapped to the first group or a second codepoint mapped to the second group.

摘要： A method allocates radio resources for a transmitting user equipment (UE) to perform direct communication transmissions over a direct sidelink connection to one or more receiving UEs. At least two sidelink grant processes are provided in the transmitting UE for the transmitting UE to handle at least two sidelink grants within the same transmission control period. Each one of the sidelink grant processes is associated with an identification and can be associated with one sidelink grant. The transmitting UE acquires at least two sidelink grants and associates each of the acquired sidelink grants with one sidelink grant process. For each sidelink grant, the transmitting UE allocates radio resources according to the respective sidelink grant to perform a direct communication transmission of sidelink control information and of data over the direct sidelink connection. The transmitting UE performs a direct communication transmission per acquired sidelink grant within the same transmission control period.

摘要： A user equipment (UE), a base station, a baseband processor or other network device can operate to perform an inter-UE coordination (IUC) operation for a sidelink (SL) communication by processing an IUC message that comprises at least one of: receiving UE sensing results associated with directional sensing or beam alignment SL control channel/sidelink data channel transmission information. The SL communication can then be transmitted based on resources selected in resource selection from the IUC.

摘要： A communication method of a terminal with another terminal through a sidelink may provide information related to a demodulation reference signal (DMRS). A user device may demodulate a Physical Sidelink Control Channel (PSCCH) DMRS and a Physical Sidelink Shared Channel (PSSCH) DMRS, and may demodulate a PSCCH based on the demodulated PSCCH DMRS and demodulate a PSSCH based on the demodulated PSSCH DMRS.
