Abstract: A method and apparatus for controlling radio resource of a redundant route for a dual-connecting Integrated Access and Backhaul (IAB) node in a wireless communication system will be provided. The CU of the IAB-donor is connected with a dual-connecting IAB-node via a master cell group (MCG) IAB-node. The CU of the IAB-donor initiates an establishment of a connection with the dual-connecting IAB-node via a secondary cell group (SCG) IAB-node. The CU of the IAB-donor transmits, to the SCG IAB-node, a first information which informs not allocating radio resource for a bearer. The CU of the IAB-donor determines to use the connection with the dual-connecting IAB-node via the SCG IAB-node. The CU of the IAB-donor transmits, to the SCG IAB-node, a second information to request allocating the radio resource for the bearer.

Abstract: A method and apparatus for support of energy efficient operation of a wireless device, e.g., a user equipment (UE), in a 5th generation new radio access technology (5G NR) is provided. A source node acquires information related to power consumption of a wireless device and transmits a message for initiation of handover. The message includes information related to energy efficiency of the wireless device. The information related to energy efficiency is based on the information related to power consumption of the wireless device. The target node performs admission control and/or resource allocation for the wireless device based on the information related to energy efficiency of the wireless device.

Abstract: A method and apparatus for paging for multicast and broadcast service in a wireless communication system is provided. A Distributed Unit (DU) of a Radio Access Network (RAN) node may receive, from a central unit (CU) of the RAN node, a service identity for a Multicast and/or Broadcast (MB) service. A MB session may be set for the MB service. A DU of a RAN node may transmit, to multiple User Equipments (UEs) in Connection Management (CM)-IDLE state, the service identity of the MB service. The multiple UEs may have joined to the MB session. A DU of a RAN node may receive, from at least one UE among the multiple UEs, an RRC message to request the MB service. A DU of a RAN node may forward the RRC message to the CU of the RAN node.

Abstract: A method and apparatus for providing beam related information for connection failure detection in a wireless communication system is provided. In case that radio link failure (RLF) occurs due to too late handover, too early handover or handover to wrong cell, a gNB in which a user equipment (UE) attempts to re-establish or establish a radio resource control (RRC) connection provides RLF related information with beam related information to a gNB at which RLF happened.

Abstract: A method and apparatus for enhancing a handover procedure for supporting conditional handover in a wireless communication system. A source base station (e.g. source gNB/eNB) receives a message informing that a wireless device is handed over from the source base station to a target base station (e.g. target gNB/eNB). The target base station is one of candidate target base stations in the conditional handover procedure. After receiving the message, the source base station transmits a sequence number (SN) status transfer message to the target base station.

Abstract: Provided are a method and an apparatus for supporting security of user traffic when a central unit (CU)-control plane (CP) and a CU-user plane (UP) of a gNB are separated in a wireless communication system. According to an embodiment of the present invention, the CU-CP of the gNB selects an encryption algorithm, generates a user plane security key for the CU-UP on the basis of the encryption algorithm, and transmits the user plane security key for the CU-UP to the CU-CP. The CU-UP applies the received user plane security key. The CU-CP is a logical node constituting the gNB that hosts a radio resource control (RRC) 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.
