Abstract: One disclosure of the present specification provides a method in which a user equipment (UE) performs an attach request procedure. The method comprises a step of transmitting an attach request message to a second system when an intersystem change from a first system to the second system is required in a state where a back-off timer associated with a data network name (DNN) based congestion control is running. The attach request message may include information on a packet data unit (PDU) session used by the UE in the first system. The information on the PDU session may be used so as not for the attach request message to be rejected by a second network, even if the back-off timer associated with the DNN-based congestion control is running.

Abstract: A user equipment according to the present invention performs a handover from a first system to a second system. When a user equipment receives a command to hand over to the second system, while using a plurality of protocol data unit (PDU) sessions for the same data network (DN) in the first system, the user equipment transmits first session information of a first PDU session among the plurality of PDU sessions, establishes a packet data network (PDN) connection with the second system, on the basis of the first session information, and maps the first PDU session to the PDN connection. When the user equipment is required to establish a dedicated bearer for a PDU session (second PDU session) other than the first PDU session among the plurality of PDU sessions, the user equipment transmits a bearer generation request message requesting to generate a dedicated bearer for the PDN connection.

Abstract: A method and apparatus for triggering a transmission carrier reselection procedure due to high congestion level in a wireless communication system is provided. A wireless device, which selects a carrier and performs data transmission on the carrier, determines that a congestion level of the carrier is not below a threshold for carrier reselection, and triggers the carrier reselection.

Abstract: A method and apparatus for supporting a fast link recovery and link status reporting in a wireless communication system is provided. When a node detects a radio link problem on a wireless backhaul link between integrated access and backhaul (IAB) nodes from the node to a donor node of an TAB network, the node reselects a cell operated by a gNB which is directly connected to the donor node, and performs a random access procedure towards the cell operated by the gNB to report information on the radio link problem to the cell. The donor node may establish a new path for the node.

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.
