Abstract: Provided is a method for configuring a release cause by a user equipment (UE) in a wireless communication system. The method may include: receiving a configuration of inactivity timer, from a base station (BS); when the data inactivity timer is expired, configuring the release cause for leaving connected state, wherein the configured release cause prevents the UE from initiating a random access procedure.

Abstract: Provided are a method for a user equipment (UE) to perform early data transmission (EDT) in a wireless communication, and an apparatus supporting the same. The method may include: transmitting a first radio resource control (RRC) message for the EDT, to a base station; receiving a second RRC message in response to the first RRC message, from the base station; if the second RRC message indicates that the EDT is successful, considering that the EDT ends successfully; if the second RRC message indicates that the EDT is unsuccessful, considering that the EDT ends unsuccessfully; and entering a RRC_IDLE state.

Abstract: Provided are a method for a user equipment (UE) to perform early data transmission (EDT) in a wireless communication, and an apparatus supporting the same. The method may include: receiving system information including a threshold for the EDT; determining whether or not a condition for initiating the EDT is satisfied, by comparing the threshold for the EDT with a size of data for transmission; if the condition is satisfied, performing the EDT; and if the condition is not satisfied, performing a radio resource control (RRC) connection establishment or resume procedure.

Abstract: A method and apparatus for support of CU-DU split in MT-EDT procedure in a wireless communication system is provided. A Central Unit (CU) of a Radio Access Network (RAN node) receives, from a Distributed Unit (DU) of the RAN node, second information related to a transport block used for the wireless device. The CU decides a Radio Resource Control (RRC) state for transmitting the downlink (DL) data to the wireless device based on the first information related to the DL data and the second information related to the transport block.

Abstract: A method and apparatus for reporting data transmission procedure failure for network optimization in a wireless communication system is provided. A wireless device performs the data transmissions to a network in idle state and/or inactive state. A wireless device detects failures of the data transmissions. A wireless device logs information related to each of the failures and counts a number of the failures, while the logging validity timer is running. A wireless device establishes or resumes a connection with the network based on that the counted number is equal to or bigger than a threshold value.

Abstract: A method and apparatus for handling failures in transmission using PUR in a wireless communication system is provided. A wireless device receives, from a network, preconfigured uplink resource (PUR) configuration. A wireless device detects that each resource of the PUR is not successfully used for uplink (UL) transmission. A wireless device informs the failure cause and/or the expected behavior based on the PUR configuration. A wireless device receives, from a network, reconfiguration of the PUR.
