Abstract: Provided are a method for performing, by a user equipment (UE), transmission via only a primary path in a wireless communication system, and an apparatus supporting the same. The method may include: configuring a split bearer, which has multiple L2 entities for both a master cell group (MCG) and a secondary cell group (SCG); when the UE transits from a first state to a second state, reconfiguring the primary path of the split bearer autonomously; and performing the transmission via only the primary path of the split bearer, wherein the primary path is related to an L2 entity for the MCG.

Abstract: Provided are a method by which an access stratum (AS) layer of a terminal determines a radio resource control (RRC) state in a wireless communication system, and a device for supporting the same. The method can comprise the steps of: entering an RRC_INACTIVE state; receiving, from a core network (CN), CN paging in the RRC_INACTIVE state; forwarding a UE ID of the terminal and a CN domain to a non-access stratum (NAS) layer of the terminal; receiving an RRC connection release request from the NAS layer of the terminal; and entering an RRC_IDLE state on the basis of the received RRC connection release request.

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 first network device receives a request associated with data notification for a user equipment (UE). When the UE is in a mode in which communication of mobile terminated data is restricted and the first network device detects that the UE is in a non-allowed area, the first network device rejects the request unless the data notification is for a regulatory prioritized service.

Abstract: A method and apparatus for performing a conditional cell change in a wireless communication system is provided. A wireless device receives a conditional mobility configuration associated with multiple target cells from a serving node. The conditional mobility configuration includes mobility commands for each of the multiple target cells. The wireless device receives information on one target cell among the multiple target cells from the serving node, and performs a mobility towards the one target cell based on a mobility command for the one target cell.

Abstract: A method and apparatus for transmitting data in a wireless communication system is provided. A user equipment (UE) transmits the data in a first cell during a first random access procedure, i.e. early data transmission. The UE detects that transmission of the data in the first cell during the first random access procedure has failed, and prioritizes a second cell based on candidate cell information. After selecting the second cell, the UE transmits a failed part of the data in the second cell during a second random access procedure.

Abstract: Provided are a method of performing public land mobile network (PLMN) selection and a device supporting the method. According to one embodiment of the present invention, a method for performing PLMN selection in a wireless communication system includes: entering an RRC_INACTIVE state; transmitting, to a non-access stratum (NAS) layer of the UE, information on whether or not there is on-going data; receiving, from the NAS layer of the UE, a request of a PLMN searching when there is no on-going data; and performing the PLMN searching based on the request of the PLMN searching.

Abstract: A method of reporting integrity verification failure by a user equipment (UE) in a wireless communication system. The method includes: receiving a data unit from a network; performing integrity verification using the data unit; and when the integrity verification fails, reporting information about the integrity verification failure to the network. The information about the integrity verification failure includes: (i) a radio bearer identity associated with the integrity verification failure, and (ii) at least one Packet Data Convergence Protocol (PDCP) COUNT value associated with the radio bearer identity.

Abstract: Provided are a method for keeping, by a user equipment (UE), a first dual connectivity (DC) configuration in a wireless communication system. The method may include: receiving information for validation of a DC configuration, from a network, wherein the DC configuration includes the first DC configuration and a second DC configuration; determining whether or not the first DC configuration is valid in a radio resource control (RRC) resume procedure, based on the information for validation of DC configuration; if the first DC configuration is valid, keeping the first DC configuration in an RRC resume procedure; and releasing the second DC configuration before initiating the RRC resume procedure.

Abstract: Provided are a method by which a terminal performs an access barring check in a wireless communication system and a device for supporting the same. The method may include: a step for entering an RRC_INACTIVE state; a step for performing the access barring check on a cell; a step for checking that access to the cell is prevented as many times as the maximum number of access attempts; and a step for transitioning from the RRC_INACTIVE state to an RRC_IDLE state.
