摘要： Provided are a method for performing, by a first device, group cast communication with one or more second devices in a group, and a device for supporting same. The method may comprise the steps of: determining the number of physical sidelink feedback channel (PSFCH) resources associated with a physical sidelink shared channel (PSSCH) resource; on the basis of the number of PSFCH resources and the size of the group, determining a hybrid automatic repeat request (HARQ) feedback option; and transmitting, to the one or more second devices, information associated with the HARQ feedback option. Here, the HARQ feedback option can be any one of a first HARQ feedback option or a second HARQ feedback option.

摘要： An embodiment is a method for operating a relay UE related to a sidelink relay in a wireless communication system, the method comprising steps for the relay UE to: deliver a sidelink grant request including a Packet Delay Budget (PDB) of a remote UE to a base station; and receive an uplink grant configuration and a sidelink grant configuration from the base station as a response to the sidelink grant request, wherein only information related to the sidelink grant configuration among the uplink grant configuration and the sidelink grant configuration is delivered by the relay UE to the remote UE. The uplink grant configuration is used for delivering packets of the remote UE to the base station, wherein the packets are packets received through a resource indicated by the sidelink grant configuration, and the resource indicated by the sidelink grant configuration and a resource indicated by the uplink grant configuration both satisfy the PDB.

摘要： A method and apparatus for sidelink hybrid automatic repeat request (HARQ) feedback and resource pool selection is provided. When user equipment (UE) autonomous resource selection is configured, a wireless device selects a resource pool configured with physical sidelink feedback channel (PSFCH) resources, among one or more resource pools allowed for a logical channel, based on i) sidelink data being available in the logical channel, ii) any resource pool being not selected for the logical channel, and iii) hybrid automatic repeat request (HARQ) feedback being enabled for the logical channel.

摘要： A method and apparatus for soft buffer flushing based on media access control (MAC) reset for radio resource control (RRC) connection between wireless devices is provided. A first wireless device operating in a wireless communication system receives, from a second wireless device, data for a transport block (TB) associated to one PC5-radio resource control (RRC) connection among one or more PC5-RRC connections. Based on a media access control (MAC) reset being requested for the one PC5-RRC connection by an upper layer of the first wireless device, the first wireless device flushes soft buffers of all sidelink processes for all TBs associated to the one PC5-RRC connection.
