    摘要: Provided are a method by which a first device performs wireless communication and a device supporting same. The method may comprise the steps of: obtaining information related to a resource pool; obtaining one or more sidelink (SL) discontinuous reception (DRX) configurations; selecting a destination having a highest priority logical channel from among logical channels having available SL data; generating a medium access control (MAC) protocol data unit (PDU) on the basis of at least one logical channel belonging to the destination; determining a packet delay budget (PDB) on the basis of a PC5 5G Quality of Service (QoS) Identifier (5QI) (PQI); on the basis of sensing, determining a plurality of candidate resources in the resource pool within a selection window; and selecting a transmission resource for SL transmission to a second device associated with the destination from among the plurality of candidate resources.

    摘要: Proposed, in an embodiment, is a method for a first device to perform wireless communication. The method may comprise the steps of: establishing a radio resource control (RRC) connection with a second device; receiving, from the second device, a sidelink discontinuous reception (SL DRX) configuration including information related to an SL DRX cycle and information related to a timer for an active time; starting the timer; receiving first sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH), the first SCI being received from the second device through a physical sidelink control channel (PSCCH) on the basis of a first resource; and receiving second SCI and data from the second device through the PSSCH on the basis of the first resource. For example, the first SCI may include resource allocation information. For example, the timer may be stopped on the basis of the resource allocation information only including information about the first resource.

    摘要: An embodiment proposes a method for performing wireless communication by a first device. The method may comprise the steps of: selecting a first resource within a first selection window on the basis of first sensing; generating a first medium access control (MAC) protocol data unit (PDU) on the basis of at least one logical channel (LCH) in which hybrid automatic repeat request (HARQ) feedback is enabled; transmitting, to a second device, first sidelink control information (SCI) for scheduling a first physical sidelink shared channel (PSSCH), through a first physical sidelink control channel (PSCCH), on the basis of the first resource; and transmitting, to the second device, second SCI and the first MAC PDU, through the first PSSCH, on the basis of the first resource. For example, random selection of the first resource may not be allowed on the basis of the at least one LCH in which the HARQ feedback is enabled.

    摘要: The present disclosure relates to access control in a wireless communication system. According to an embodiment of the present disclosure, a method performed by a first user equipment (UE) in a wireless communication system comprises: receiving a discovery message broadcast by a second UE, the discovery message comprising access control information for a cell in which the second UE is in a connected state; performing access barring check for the cell based on the access control information; selecting a third UE for obtaining a network connection based on an access attempt to the cell being barred as a result of the access barring check; and performing an access attempt to acquire the network connection through the third UE.

    摘要: Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: determining a channel occupancy time (COT) based on sensing for channel access; transmitting, to a second device, information related to the COT; transmitting, within the COT, first sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH) and second SCI through a physical sidelink control channel (PSCCH); transmitting, within the COT, the second SCI and a medium access control (MAC) protocol data unit (PDU) through the PSSCH; determining to terminate the COT; and transmitting, to the second device, information related to COT termination based on the determination.

    摘要: 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.
