Abstract: A method and apparatus for fast small data transmission in a wireless communication system is provided. A last serving RAN node receives, from the wireless device and via a new RAN node, an AS-RAI related to early data transmission. A last serving RAN node decides whether a UE context relocation to the new RAN node for the wireless device is required or not based on the received AS-RAI. A last serving RAN node transmits, to the new RAN node, an RRC message based on the decision.

Abstract: A method and apparatus for adaptive QoE management in a RAN node in a wireless communication system is provided. A CU-CP receives, from a CN node, a first message informing a certain service to which an adaptive QoE management is applied. A CU-CP transmits, to a CU-UP and/or a DU, a second message informing that the adaptive QoE management is applied to the certain service. A CU-CP receives, from the CU-UP and/or the DU, a third message related to measurement results on the certain service based on the measurement information.

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.
