Abstract: The present invention relates to a method of a base station transmitting a coverage compensation request signal to determine switching to an idle state. The method comprising: transmitting, by the first base station, an idle switching request message for requesting switching to the idle state to a second base station in a compensation group to which the first base station belongs; transmitting a Coverage Compensation Request Message to a compensation base station pre-linked to the first base station in the compensation group; receiving a Coverage Compensation Response Message and an idle state switching response message from the compensation base station and the second base station, respectively; determining whether the first base station and the second base station in the compensation group are to switch to the idle state based on the received Coverage Compensation Request Message and the idle state switching response message.

Abstract: A method and apparatus for small data transmission in RRC inactive state in MR-DC is provided. A MN, in a DC for a wireless device, transmits, to the wireless device, a paging message including an indication related to an EDT procedure for the SN. A MN receives, from the wireless device, an AS-RAI related to the EDT procedure for SN. A MN decides whether to continue the EDT procedure to the wireless device for the DL data or to transit the wireless device to the RRC-CONNECTED state based on the received AS-RAI.

Abstract: A method and apparatus for supporting an early data transmission (EDT) in a radio resource control (RRC) inactive state is provided. The current gNB receives a resume request message including uplink (UL) data from the wireless device, and transmits a logical channel identifier (LCID) for the UL data to the last serving gNB. The last serving gNB transmits UL forwarding user plane (UP) transport network layer (TNL) information to the current gNB based on mapping between the LCID for the UL data and data radio bearer (DRB) ID or protocol data unit (PDU) session ID in a UE context stored in the last serving gNB. The current gNB forwards the UL data to a core network via the last serving gNB based on the UL forwarding UP TNL information.

Abstract: A method and apparatus for controlling mobile early data transmission (EDT) procedure in a wireless communication system is provided. A first core network node, in a wireless communication, receives, from a second core network node, a message for a downlink Data including a size of the downlink data. The first core network node determines whether to initiate an early data transmission (EDT) procedure for the downlink data based on the size of the downlink data. The first core network node transmits, to a radio access network (RAN) node, a paging message including information related to the EDT procedure for the downlink data based on the decision to initiate the EDT procedure for a wireless device.
