Abstract: A disclosure of the present specification provides a method for transmitting a radio resource control (RRC) message by a wireless device. The method may comprise the steps of: acquiring, by an access stratum (AS) layer of a wireless device, at least one of the value and indication of an RRC establishment cause field from a non-access stratum (NAS) layer which requests transmission of an NAS signaling request message; transmitting, to a base station, an RRC connection request message including the at least one of the value and indication of the RRC establishment cause field; and when the at least one of the value and indication of the RRC establishment cause field is set to a value, which indicates that the NAS signaling request message includes user data, according to an optimization scheme through a control plane (CP), if a network is in an overload state, receiving an RRC connection rejection message or an RRC connection release request message from the base station.

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.

Abstract: A method and apparatus for resuming only signaling radio bearers (SRBs) in a wireless communication system is provided. A wireless device triggers a signaling while the wireless device is in a radio resource control (RRC) inactive state, and resumes only SRB and transmits a message 3 (MSG3) of a random access procedure to a network when an early data transmission (EDT) triggering condition for transmission via the MSG3 is fulfilled. The MSG3 includes the signaling.

Abstract: A method and apparatus for random access procedure based on a beam quality in a wireless communication system is provided. A wireless device monitors a paging including information on one or more beams associated with a contention free random access procedure and selects at least one beam of which a quality is above a threshold among the one or more beams. The wireless device performs the contention free random access procedure via the at least one beam. When there is no beam of which the quality is above the threshold, the wireless device performs a contention based random access procedure.
