Abstract: A method and apparatus for identification of a sidelink connection associated with multiple sessions in a wireless communication system is provided. A first wireless device establishes a first session based on a first upper layer identifier (ID) of the first wireless device, which is associated with the first session. Then, the first wireless device allocates a lower layer ID of the first wireless device, and transmits the lower layer ID of the first wireless device to the second wireless device. The first wireless device establishes a second session based on a second upper layer ID of the first wireless device, which is associated with the second session, and the lower layer ID of the first wireless device, and performs sidelink transmission for the second session to the second wireless device.

Abstract: A method for a user equipment (UE) to perform public land mobile network (PLMN) selection in a wireless communication system, and which includes selecting, by the UE, a first PLMN; in response to the first PLMN not providing direct communication resources, selecting, by the UE, a second PLMN providing direct communication resources; performing, by the UE, a registration on the second PLMN; receiving, by the UE, a failed registration code of “PLMN not allowed” due to a failing of the registration on the second PLMN; and performing, by the UE, the direct communication on the second PLMN in a limited service state. Further, the UE remains on the first PLMN based on a normal service state and the UE does not perform an additional PLMN selection during a duration of the direct communication in the second PLMN based on the limited service state.

Abstract: A method of performing a radio resource control (RRC) connection procedure of a relay user equipment (UE) in a wireless communication system is disclosed. The method includes, if a RRC connection procedure of a remote UE associated with the relay UE is triggered, receiving, from the remote UE, a first RRC establishment cause for a RRC connection of the remote UE; and if a RRC connection request of the relay UE is not allowed, transmitting, to a base station, a first RRC connection request including the first RRC establishment cause of the remote UE.

Abstract: One disclosure of the present specification provides a method by which a session management function (SMF) supports quality of service (QoS). The method can comprise the steps of: determining, on the basis of a QoS flow not being a guaranteed bit rate (GBR) QoS flow in a multi-access (MA) protocol data unit (PDU) session, that a QoS profile is transmitted to both a third generation partnership project (3GPP) access and a non-3GPP access; determining, on the basis of the QoS flow being the GBR QoS flow in the MA PDU session, that the QoS profile is transmitted to only one of the 3GPP access and the non-3GPP access; and transmitting the QoS profile on the basis of the determinations.

Abstract: Disclosed are a method for transmitting and receiving data through a relay in a wireless communication system and an apparatus therefor. Specifically, a method for transmitting and receiving, by a remote user equipment (UE), data to and from a network through a relay UE in a wireless communication system includes: recognizing that small data to be transmitted to the network is generated; performing a discovery procedure through the relay UE and a PC5 interface; and transmitting a PC5 message including the small data to the relay UE when it is verified that the relay UE has an ability to transmit the small data to the network in the discovery procedure, in which when it is indicated that the relay UE supports a small data transmitting procedure by a PC5 discovery message received from the relay UE in the discovery procedure, it may be determined that the relay UE has the ability to transmit the small data to the network.

Abstract: Systems and techniques for handling a protocol data unit (PDU) session by a wireless device implementing an access stratum (AS) layer and a non-access stratum (NAS) layer in a wireless communication system. An example technique includes determining, by the AS layer of the wireless device, whether a user plane for the PDU session is activated or released; transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is activated, first information indicating that the user plane for the PDU session is activated; and transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is released, second information indicating that the user plane for the PDU session is released.
