Abstract: A method and apparatus for small data transmission without a path switch procedure in a wireless communication system is provided. A new gNB, which is a radio access network (RAN) node to which a wireless device attempts a connection resume procedure while in an inactive state, receives an anchor kept indication and/or a small data indication from a last serving gNB. The anchor kept indication indicates that the last serving gNB keeps a user equipment (UE) context and/or a UE-associated NG connection with the core network. The small data indication indicates not relocating a UE context from the last serving gNB to the new gNB.

Abstract: Provided are a method for early data transmission. According to an embodiment of the present disclosure, the method includes transmitting a radio resource control (RRC) connection resume request message to a control plane (CP) of central unit (CU) of the network node, receiving information informing that downlink (DL) data exists from the CP, receiving DL data from a user plane (UP) of the CU, transmitting the DL data to a wireless device in response to the information, upon receiving the DL data, and releasing transmission resources after transmitting the DL data.

Abstract: One disclosure of the present specification provides a method by which an AMF performs communication related to a network slice. The method may comprise the steps of: receiving a PDU session establishment request message including information about a second PDU session; determining to forward a UE to a second RAN node supporting a second network slice; transmitting a message including information indicating that the UE needs to be forwarded to the second RAN node supporting the second network slice; receiving a handover required message; and transmitting a request message for deactivating the first PDU session related to a first network slice.

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: Provided are a method for resuming, by a distribution unit (DU) of a base station, a radio resource control (RRC) connection in a wireless communication system, and an apparatus for supporting the same. The method may comprise the steps of: receiving, from a terminal, an RRC connection resume request message; transmitting, to a central unit (CU) of the base station, an initial uplink (UL) RRC message transfer message including the RRC connection resume request message; receiving, from the CU, a UE context setup request message including a list of radio bearers to be set up; and transmitting, to the CU, the UE context setup response message including a list of established radio bearers.

Abstract: A method and apparatus for preventing loss of uplink data in wireless communication system is provided. A central unit (CU) of an integrated access and backhaul (IAB)-donor receives, from a wireless device, uplink data through a source IAB-node. The CU of the IAB-donor receives, from the source IAB-node, a message which informs that uplink packets among the uplink data are remained on the source IAB-node, wherein the message is related to handover procedures of the wireless device from the source IAB-node to a target IAB-node. The CU of the IAB-donor proceeds the handover procedures, after receiving the uplink packets.

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: Provided are a method in which a source distribution unit (DU) of a base station stops transmitting data to a user equipment (UE) in a wireless communication system, and an apparatus supporting the method. The method may include: receiving, from a central unit (CU) of the base station, a message indicating to stop transmitting data to the UE; and stopping transmitting data to the UE, upon receiving the message from the CU of the base station.

Abstract: Provided are a method by which a base station controls the access of a terminal, and a device for supporting the same. The method comprises the steps of: receiving, from a core network, information on an RRC connection procedure in which access in an RRC inactive state is restricted; receiving a request for executing the RRC connection procedure from a terminal which is in the RRC inactive state; and transmitting, to the terminal, a message notifying that the requested execution of the RRC connection procedure has been restricted, when the RRC connection procedure requested from the terminal corresponds to the RRC connection procedure in which the access is restricted.

Abstract: One disclosure of the present specification provides a method for supporting redundant protocol data unit (PDU) sessions. The method may be performed by a unified data management (UDM) node and comprise: receiving, from a first session management function (SMF) node, a first message including a first redundancy sequence number (RSN) which is allocated by the first SMF node for managing a first PDU session and an identifier of the first PDU session; transmitting, to a second SMF node for managing a second PDU session, a second message including the first RSN and a PDU session pair ID, which is identical to the identifier of the first PDU session; and receiving, from the second SMF node, a third message including a second RSN which is allocated by the second SMF node and an identifier of the second PDU session. The second PDU session may be duplication of the first PDU session.
