Abstract: Provided are a method by which a base station performs vehicle to everything (V2X) communication in a wireless communication system, and an apparatus for supporting the same. The method can comprise the steps of: receiving a V2X bearer indication indicating a V2X bearer, wherein the V2X bearer is a bearer used for a V2X service; determining that the base station supports only a PC5-based V2X service between the PC5-based V2X service or a Uu-based V2X service; postponing a resource allocation for the V2X bearer; and transmitting, to a mobility management entity (MME), information indicating that the resource allocation for the V2X bearer is postponed.

Abstract: A method and apparatus for deprioritizing duplicated packet transmission in a wireless communication system is provided. A user equipment (UE) generates a first packet, a second packet and a third packet. The third packet is duplication of the second packet. The UE deprioritizes the third packet under the first packet when the second packet is prioritized over the first packet. The first packet may be a packet for uplink transmission, and the second packet and the third packet may be packets for sidelink transmission.

Abstract: A user equipment (UE) (first UE) receives setting information about a plurality of transmission (Tx) resource pools and a plurality of reception (Rx) resource pools for a cell. On the basis of the setting information, and the identity (ID) of the first UE (first UE ID) or the ID of another UE (second UE) (second UE ID) connected for proximity-based wireless communication with the first UE, the first UE determines a portion (Tx resource group) of the plurality of Tx resource pools and a portion (Rx resource group) of the plurality of Rx resource pools. The first UE performs sidelink transmission to the second UE by using a Tx resource pool which belongs to the Tx resource group. The first UE performs sidelink reception from the second UE by using an Rx resource pool which belongs to the plurality of Rx resource groups.

Abstract: A method for a terminal to receive downlink user data in a wireless communication system and a device supporting the method are provided. The method may comprise: a step of entering an RRC_INACTIVE state; a step of receiving, from a base station, a notification indication indicating if downlink data is transmitted in the RRC_INACTIVE state; a step of transmitting an ID of a terminal to the base station; and a step of receiving, based on the indication, a data unit from the base station in the RRC_INACTIVE state.

Abstract: Provided are a method and a device for receiving information indicating the type of a signaling radio bearer (SRB) in a wireless communication system. A user equipment (UE): receives a first radio resource control (RRC) message including information indicating the type of SRB on which a second RRC message, which is a message corresponding to the first RRC message, is to be transmitted; and transmits the second RRC message via the type of SRB indicated by the information indicating the type of SRB. Accordingly, the type of bearer on which a first message is received and the type of bearer on which a second message is transmitted in a single RRC procedure may be identical or mutually different.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for processing system information for Machine-Type Communication system, the method comprising: receiving repetitions of system information for scheduling other SIBs in a first period; receiving an indicator indicating the system information for scheduling other SIBs is not changed in a second period followed by the first period in a specific time of the first period; and processing the system information for scheduling other SIBs based on the repetitions of the system information accumulated from the specific time of the first period if the system information for scheduling other SIBs is not successfully decoded at the time of end of the first period.

Abstract: A method and apparatus for performing a wireless local area network (WLAN) termination (WT) addition/modification procedure in a wireless communication system is provided. For the WT addition procedure, an eNodeB (eNB) transmits a WT Addition Request message to a WT via a Xw interface, and receives a WT Addition Request Acknowledge message from the WT via the Xw interface. For eNB initiated WT modification procedure, the eNB transmits a WT Modification Request message to a WT via a Xw interface, and receives a WT Modification Request Acknowledge message from the WT via the Xw interface. For the WT initiated WT modification procedure, the eNB receives a WT Modification Required message from a WT via a Xw interface, and transmits a WT Modification Confirm message to the WT via the Xw interface. The WT is a logical node that terminates the Xw interface.

Abstract: One disclosure of the present specification provides a method for supporting early data transmission (EDT) by a base station. The method may comprise a step of receiving a first message from a mobility management entity (MME). A first NAS message may include downlink data. The method may further comprise a step of confirming that there is no additional data other than the downlink data, on the basis of reception of the first NAS message.
