Abstract: A method and apparatus for access control for data transmission in idle mode and/or inactive mode in a wireless communication system is provided. An allowed timer is defined, and the allowed timer is started based on a result of access barring check. While the allowed timer is running, the wireless device can perform an uplink (UL) transmission without further access barring check.

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 is a method for changing, by a user equipment (UE), packet data convergence protocol (PDCP) version. The method may include: receiving a security mode command message, which includes a first security algorithm configuration for a PDCP of a first system and a second security algorithm configuration for a PDCP of a second system, from a base station (BS); deriving a first security key for the PDCP of the first system, based on the first security algorithm configuration; when the security mode command message passes an integrity protection check based on the first security key, changing the PDCP version from the PDCP of the first system to the PDCP of the second system; deriving a second security key for the PDCP of the second system, based on the second security algorithm configuration; and transmitting a security mode complete message, based on the second security key, to the BS.

Abstract: Provided are a method for transmitting a message by a user equipment (UE) in a wireless communication, and an apparatus supporting the same. The method may include: initiating early data transmission; receiving a random access response message including an uplink grant, from a base station (BS); based on the uplink grant, determining whether or not to transmit a first message related to the early data transmission to the BS, in response to the random access response message; and after determining to transmit the first message related to the early data transmission, resuming radio bearers for the early data transmission.

Abstract: Provided are a method of performing cell reselection and a device supporting the method. According to one embodiment of the present disclosure, the method includes: starting data transmission or data reception while the UE is in radio resource control (RRC) idle state or RRC inactive state; applying an offset value to a serving cell for cell reselection; performing cell reselection based on the applied offset value, during the data transmission or data reception; and stopping applying the offset value to the serving cell, when the data transmission or data reception is succeeded.

Abstract: A method of operating a Tx user equipment (UE) in a wireless communication system includes receiving radio access network (RAN) paging by the Tx UE, initiating a radio resource control (RRC) resume procedure by the Tx UE, and transmitting an RRC message based on sidelink radio link failure (RLF) to a base station (BS) by the Tx UE. The RRC message is related to reporting of the sidelink RLF to the BS, and includes a destination identifier (ID) related to the sidelink RLF.

Abstract: A method and an apparatus for reselecting Tx carrier for sidelink transmission in wireless communication system is provided. The method, by a UE, may include selecting a first carrier upon which the wireless device performs first sidelink transmission based on the first carrier to a target wireless device, detecting a number of retransmissions unacknowledged on the first carrier, and performing second sidelink transmission to the target wireless device based on a second carrier different from the first carrier.

Abstract: Provided are a measurement reporting method of a terminal in which a primary cell is set and a terminal apparatus using the measurement reporting method. The method comprises: a step for adding a secondary cell; a step for determining whether the secondary cell is applicable to related measurement; and a step for determining whether the secondary cell is included in a cellsTriggeredList, wherein when the secondary cell is not applicable to the related measurement and the secondary cell is included in the cellsTriggeredList, the secondary cell is removed from the cellsTriggeredList.
