According to an embodiment of the present disclosure, provided is a method by which a first apparatus performs sidelink communication. The method may comprise the steps of: transmitting a first transport block to a second apparatus, on a resource allocated by a first SL grant received from a base station; transmitting, to the base station, a system information request message requesting system information; transmitting, on an exceptional resource pool, a second transport block to the second apparatus, on the basis of the transmission of the system information request message to the base station; and receiving, from the base station, first system information related to the system information request message.

Method and apparatus for performing resource pool-based sidelink communication in NR V2X

The present disclosure provides a method of receiving a physical downlink shared channel (PDSCH) by a user equipment (UE) in a wireless communication system. The method may include: receiving a parameter related to discontinuous reception (DRX) operation through a higher layer; receiving first downlink control information (DCI) including information related to physical downlink control channel (PDCCH) monitoring adaptation; receiving second DCI for scheduling the PDSCH within a DRX active time of the DRX operation, based on the information related to the PDCCH monitoring adaptation; and receiving the PDSCH based on the second DCI. The PDCCH monitoring adaptation may be determined based on jitter related to the PDSCH.
