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: The present invention relates to a method for V2X (vehicle-to-everything) communication performed by means of a terminal in a wireless communication system, the method characterized by: determining whether or not the transmission points of feedback information for sidelink semi-persistent scheduling (SPS) information and feedback information for a wide area network (WAN) physical downlink shared channel (PDSCH) overlap; and transmitting the feedback information for the sidelink SPS information and the feedback information for the WAN PDSCH on the basis of the determination, wherein, if the transmission points of the feedback information for the sidelink SPS information and the feedback information for the WAN PDSCH overlap, the feedback information for the sidelink SPS information and the feedback information for the WAN PDSCH are transmitted by means of multiplexing or transmitted on the basis of priority.

Abstract: As a channel busy ratio (CBR) is defined to measure the congestion of a PC5 interface in order to support an effective vehicle-to-everything (V2X) communication, an eNodeB (eNB) transmits CBR information of a sidelink channel to a user equipment (UE) for each resource pool used for V2X communication. The user equipment which has received the CBR information determines if there is a usable CBR and, if it is determined that there is no usable CBR, can use the received CBR information.

Abstract: Provided in one disclosure of the present specification is a method for a wireless device attempting network access. The method may comprise the steps of: an RRC layer of the wireless device receiving, from a cell, a first piece of information relating to an NB-IoT RAT; the RRC layer receiving, from the cell, a second piece of information indicating whether to block access to exception data; the RRC layer obtaining, from an upper layer, an RRC establishment cause set as outgoing exception data, when an NAS signaling process is initiated to transmit the exception data; and performing an access block inspection.

Abstract: According to the present disclosure, a user equipment (UE) selects a carrier among a plurality of carriers, receives information on a channel busy ratio (CBR) threshold from a network, and triggers a carrier reselection. When a CBR of the carrier satisfies the CBR threshold, e.g. the CBR of the carrier is below than the CBR threshold, the UE keeps using the carrier. That is, the carrier reselection is not performed when the CBR of the carrier satisfies the CBR threshold. On the other hand, when a CBR of the carrier does not satisfy the CBR threshold, the UE performs the carrier reselection.

Abstract: A method for a base station (BS) operating in a wireless communication system, the method includes transmitting, to a user equipment (UE), first information indicating a threshold value for an uplink data split operation; and receiving a buffer status report (BSR) from the UE, wherein a value of a buffer size in the BSR is determined based on second information that indicates an amount of data available for transmission for a packet data convergence protocol (PDCP) entity of the UE when the amount of the data available for transmission is larger than the threshold value.

Abstract: One embodiment of the present invention provides a method by which a network node performs an operation related to a vehicle to everything (V2X) message transmission to a user equipment (UE) in a wireless communication system, the method comprising the steps of: allowing the network node to receive a notify broadcast area message; allowing the network node to receive a V2X message after receiving the notify broadcast area message; and allowing the network node to determine a first eNB which will transmit the V2X message to the UE, on the basis of the notify broadcast area message, without performing session update request procedures.

Abstract: A relay user equipment (UE) linked to a remote UE relays paging to the remote UE. The relay UE transmits paging frame (PF) information and paging occasion (PO) information to the remote UE. The relay UE receives a paging message for the remote UE in a PO of the remote UE or in a PO of the relay UE within a PF of the relay UE on the basis of the PF information and the PO information. The relay UE relays the paging message to the remote UE.
