    Abstract: 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.

    Abstract: 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.

    Abstract: A method of operating a first apparatus 100 in a wireless communication system is proposed. The method may include, obtaining at least one sidelink (SL) discontinuous reception (DRX) configuration; obtaining information related to whether an SL DRX operation of a second apparatus 200 to receive a service related to a service data unit (SDU) is enabled and the SDU; determining that the second apparatus 200 performs an SL DRX operation for the service related to the SDU, based on that the information related to whether the SL DRX operation is enabled represents that an SL DRX operation of the second apparatus 200 is enabled; determining an SL DRX configuration among the at least one SL DRX configuration, based on a quality of service (QoS) requirement related to the SDU; generating a medium access control (MAC) protocol data unit (PDU) based on the SDU; and transmitting the MAC PDU to the second apparatus 200 in an active time of the SL DRX configuration.
