摘要： 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.

摘要： 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.

摘要： A method and apparatus for Sidelink (SL) Discontinuous Reception (DRX) operation based on multiple DRX configurations and prioritization is provided. A third wireless device receives, from a first wireless device, first Sidelink (SL) Discontinuous Reception (DRX) information, and receives, from a second wireless device, second SL DRX information. The third wireless device informs a network about the first and second SL DRX information, each of which is constructed for each pair of source and destination.
