Abstract: A method for a wireless device in a wireless communication system includes receiving a paging from a distribution unit (DU) of a base station; and upon receiving the paging message, initiating a service request procedure. Further, the paging is based on paging information transmitted from a central unit (CU) of the base station to the DU of the base station. The paging information includes paging discontinuous reception (DRX) information and paging priority information. The DU of the base station has a radio link control (RLC) layer, a media access control (MAC) layer and a physical layer of the base station. In addition, the CU of the base station has a radio resource control (RRC) layer, a service data adaptation protocol (SDAP) layer, and a packet data convergence protocol (PDCP) layer of the base station.

Abstract: Provided is a method in which a secondary node (SN) transmits a measurement configuration by multi radio access technology (RAT) dual connectivity. The SN receives, from a master node (MN), measurement configuration information related to a measurement configuration of the SN, transmits, to user equipment (UE), the measurement configuration on the basis of the measurement configuration information, and receives a measurement report on the basis of the measurement configuration from the UE.

Abstract: A method and apparatus for supporting a link congestion detection in a in an integrated access and backhaul (IAB) network is provided. An IAB-donor-central unit (CU) performs downlink (DL) transmission, receives information about a problem on a backhaul (BH)-radio link control (RLC) channel between a first IAB-node and a second IAB-node, and stop/reduces the DL transmission to the second IAB-node via the BH-RLC channel between the first IAB-node and the second IAB-node based on the information. The IAB-donor-CU may select a path towards the second IAB-node other than the BH-RLC channel between the first IAB-node and the second IAB-node, and perform DL transmission towards the second IAB-node via the selected path.

Abstract: A method and apparatus for discarding a buffered data in a wireless communication system is described. A central unit (CU) user plane (UP) of a gNB receives a buffered data discard indication from a CU-control plane (CU-CP) of the gNB, and discards buffered data for a user equipment (UE) based on the buffered data discard indication. Even after discarding the buffered data, UE context is still kept. The CU-CP is a logical node constituting the gNB that hosts a radio resource control (RRC) protocol and a packet data convergence protocol (PDCP)-C protocol, and the CU-UP is a logical node constituting the gNB that hosts a PDCP-U protocol.

Abstract: Provided are a method and an apparatus for performing a secondary node change procedure disclosed by a source secondary node in a wireless communication system. A master node receives a secondary node change request message from the source secondary node, transmits a secondary node addition request message to a target secondary node, receives a secondary node addition request confirm message from the target secondary node, and transmits a secondary node change request confirm message to the source secondary node.
