Abstract: Performing a radio resource control (RRC) related operation by a transmitter (TX) user equipment (UE) performing a sidelink (SL) discontinuous reception (DRX) operation in a wireless communication system. A method may include: receiving, by the TX UE, an SL DRX configuration from a base station; receiving, by the TX UE, a configured grant from the base station; performing, by the TX UE, SL transmission on a resource related to the configured grant during an active time based on the SL DRX configuration; performing, by the TX UE, an RRC connection related procedure to a network; and starting, by the TX UE, a timer for the RRC connection related procedure. The TX UE may perform transmission in an exceptional pool of the configured grant based on the SL DRX configuration after starting the timer. The SL DRX configuration may be maintained until expiration of the timer.

Abstract: Proposed is a method for a first device to perform wireless communication. The method may comprise the steps of: establishing a connection with a second device; and reselecting a cell on the basis that the first device is in a radio resource control (RRC) IDLE state or an RRC INACTIVE state. For example, a priority related to cell reselection can be set such that a cell related to a new radio (NR) has a high priority. For example, cell reselection can be performed first on the cell related to the NR on the basis of the priority related to cell reselection.

Abstract: 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.

Abstract: Proposed are a method by which a first device performs wireless communication, and an apparatus supporting same. For example, the first device may obtain a sidelink discontinuous reception configuration including information related to an SL DRX timer. For example, the first device may obtain information related to a scheduling request configuration for a SL channel state information reporting medium access control control element (CE). For example, the first device may determine the SR configuration for the SL CSI reporting MAC CE as an SR configuration for an SL DRX command MAC CE. For example, the first device may transmit, to the base station, an SR for requesting a resource for the SL DRX command MAC CE, based on the SR configuration for the SL CSI reporting MAC CE. For example, the first device may transmit, to the second device, the SL DRX command MAC CE, based on the resource.

Abstract: A method and apparatus for Sidelink (SL) Discontinuous Reception (DRX) operation based on resource allocation is provided. A first wireless device, e.g., receiving user equipment (RX UE), monitors first Physical Sidelink Control Channel (PSCCH) transmissions from a second wireless device, e.g., transmitting UE (TX UE), in a Sidelink (SL) active time for SL Discontinuous Reception (DRX). The first wireless device receives, from the second wireless device, an indication to reselection of sidelink resources, and adjusts the SL active time based on the indication. The first wireless device monitors second PSCCH transmissions from the second wireless device in the adjusted SL active time.
