Abstract: According to an embodiment of the present disclosure, a user equipment (UE) may receive configuration information for channel access based on UE-initiated channel occupancy on a shared spectrum and determine whether an uplink (UL) transmission associated with the UE-initiated channel occupancy is allowed during a first period that is based on the configuration information. Based on that resources for the UL transmission associated with the UE-initiated channel occupancy in the first period are related to a contention-based random access procedure, the UE may determine that the UL transmission associated with the UE-initiated channel occupancy is not allowed in the first period.

Abstract: Provided are a method and a device for receiving information indicating the type of a signaling radio bearer (SRB) in a wireless communication system. A user equipment (UE): receives a first radio resource control (RRC) message including information indicating the type of SRB on which a second RRC message, which is a message corresponding to the first RRC message, is to be transmitted, and transmits the second RRC message via the type of SRB indicated by the information indicating the type of SRB. Accordingly, the type of bearer on which a first message is received and the type of bearer on which a second message is transmitted in a single RRC procedure may be identical or mutually different.

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.
