Abstract: A method of operating a first user equipment (UE) in a wireless communication system includes transmitting a physical sidelink shared channel (PSSCH) on a first unicast link among two or more unicast links by the first UE, receiving a physical sidelink feedback channel (PSFCH) related to a hybrid automatic repeat and request-acknowledgment (HARQ-ACK) for the PSSCH by the first UE, and releasing a second unicast link for which radio link failure (RLF) has been declared among the two or more unicast links, based on the RLF and a PC5 link identifier (ID) by the first UE. The PC5 link ID is used to identify the second unicast link for which the RLF has been declared among the two or more unicast links.

Abstract: One disclosure of the present specification provides a method for transmitting, by user equipment, a PDU session establishment request. The method comprises the steps of: receiving a session management message based on an SSC mode from an SMF through an AMF in a state in which a back-off timer associated with a DNN-based congestion control is in operation, wherein the session management message is associated with a DNN to which the DNN based congestion control is applied; and transmitting a PDU session establishment request to the AMF for establishment of a new PDU session associated with the DNN on the basis of the session management message, wherein the PDU session establishment request includes information for preventing rejection of the PDU session establishment request, and the information for preventing the rejection may be used to make the AMF ignore the DNN-based congestion control and transmit the PDU session establishment request to the SMF associated with the new PDU session.

Abstract: One disclosure of the present specification provides a method by which a remote terminal selects any one from among relay terminals in a situation in which access control is applied because of network congestion. The method can comprise the steps of: receiving first information related to the access control from at least one of the relay terminals; comparing the first information with second information which is possessed by the remote terminal; selecting, from among the relay terminals, the relay terminal having transmitted the first information, when the first information completely coincides with the second information; and attempting a connection with the selected relay terminal.
