摘要： Provided is a method for carrying out access control in a radio resource control (RRC) connected mode according to a disclosure of the present specification. The method may comprise the steps of: a non-access stratum (NAS)layer of a terminal determining an access category if outgoing (MO) data to be transmitted or outgoing (MO) signaling occurs; the NAS layer transmitting the NAS signaling message and access category to an access stratum (AS) layer if no disconnection is determined as a result of carrying out a termination test for access control on the basis of the access category; and the AS stratum of the terminal transmitting, to a base station, an RRC message comprising at least one from among the access category, call type, and reason for setup.

摘要： A user equipment (UE) may receive or transmit a protocol data unit (PDU). The PDU includes a service data unit (SDU) type field. The SDU type field may be set to a value indicating a vehicle-to-everything (V2X) type. When the SDU type field is set to a value indicating a V2X type, the PDU may include an additional field indicating an application or protocol type for data of an SDU in the PDU.

摘要： A method for restarting a prohibit timer in a wireless communication system, the method performed by a user equipment (UE) includes starting the prohibit timer related to a transmission of power preference information; receiving, from a network, a handover message including a timer value; performing a handover procedure based on the received handover message; restarting the prohibit timer based on applying the received timer value included in the handover message; and stopping the prohibit timer based on whether the UE initiates radio resource control (RRC) re-establishment procedure while the prohibit timer is running. Further, upon initiating the RRC re-establishment procedure, the UE disables the transmission of the power preference information and stops the prohibit timer.

摘要： Disclosed in the present specification is a method by which a user equipment (UE) performs access control. The method comprises the steps of: allowing a non-access-stratum (NAS) layer of the UE to transfer information on an important service and a NAS signaling request to a radio resource control (RRC) layer, when the important service is required even if access to a cell is currently interrupted or a back-off timer is operated; and allowing the RRC layer to skip or override an inspection for access control on the basis of the information on the important service, wherein, the information on the important service can be set in advance.

摘要： In a wireless communication system of the present invention, a user equipment (UE) can receive mapping information for each of a plurality of connection categories. The UE can receive barring information for the plurality of connection categories. The UE can determine whether to perform a connection attempt to a network on the basis of the barring information and a connection category to which UE data belongs according to the mapping information.

摘要： A method for transmitting an uplink signal by a user equipment (UE). The method includes receiving an uplink grant including a new data indicator (NDI) on a physical downlink control channel (PDCCH) from a network, determining whether the PDCCH is not addressed to a temporary cell identifier, determining whether the NDI has been toggled when the PDCCH is not addressed to the temporary cell identifier, and transmitting a new data to the network when the NDI has been toggled.
