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 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: A method and apparatus for enhancing a handover procedure for supporting conditional handover in a wireless communication system. A source base station (e.g. source gNB/eNB) receives a message informing that a wireless device is handed over from the source base station to a target base station (e.g. target gNB/eNB). The target base station is one of candidate target base stations in the conditional handover procedure. After receiving the message, the source base station transmits a sequence number (SN) status transfer message to the target base station.

Abstract: A method and apparatus for acquiring system information (SI) in a wireless communication system is provided. When a user equipment (UE) moves to a (neighbor) cell and if the UE have stored system information with same system information area code (SAC), the UE reuses the stored system information (SI) and skip acquiring whole system information blocks (SIBs). If the UE does not have matched SAC, the UE checks existence of any delta SI scheduling configuration which means that a group of SI message is to be update based on the stored information. If a SI message supporting delta configuration is broadcast at a cell and if the SI message includes a parameter which UE has previously stored, the UE replaces the stored parameter by the parameter received from the SI message.
