Abstract: A user equipment (UE) receives a SPS resource configuration from an eNodeB (eNB), and transmits information related to a semi-persistent scheduling (SPS) activation for a specific logical channel to the eNB. The information may include timing information for the specific logical channel which indicates when a SPS resource for the specific logical channel should be activated. The specific logical channel may correspond to a vehicle-to-everything (V2X) communication.

Abstract: A method of operating a Tx user equipment (UE) in a wireless communication system includes transmitting a random access preamble corresponding to a synchronization signal block (SSB) by the Tx UE, receiving a random access response in response to the random access preamble by the Tx UE, establishing a link with a Rx UE by the Tx UE, and transmitting a radio resource control (RRC) message based on sidelink radio link failure (RLF) to a base station (BS) by the Tx UE. The RRC message is related to reporting of the sidelink RLF to the BS, and includes a destination identifier (ID) related to the sidelink RLF.

Abstract: In vehicle-to-everything (V2X) communication or vehicle-to-pedestrian (V2P) communication, a first user equipment (UE) transmits, at a transmission timing, first data for a specific logical channel, and determines a reception timing window on the basis of the transmission timing. A second UE transmits second data in a specific time interval that is within the reception timing window or is prior to the reception timing window, and the first UE monitors the reception timing window in order to receive the second data.

Abstract: A method for a terminal to receive system information in a wireless communication system on the basis of beam information, and a device supporting the method are provided. The method may comprise: a step of selecting a beam; a step of transmitting, to a base station, a system information request including a random access channel (RACH) preamble corresponding to the selected beam; a step of receiving a response to the RACH preamble from the base station, wherein the response to the RACH preamble includes beam information indicating a specific beam; and a step of receiving system information requested by the system information request, via the specific beam indicated by the beam information.

Abstract: A method and apparatus for channel access priority classes based on message type in a wireless communication system is provided. A wireless device obtains mapping information between message types and Channel Access Priority Classes (CAPCs). A wireless device detects a message to be transmitted. A wireless device selects a specific CAPC for the message based on the mapping information. A wireless device performs LBT procedure based on the specific CAPC. A wireless device transmits, to a second device, the message after the LBT procedure.

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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting assistance information to a network/base station when a condition is satisfied. Whether the condition is satisfied or not is determined based on scheduling information from the network/base station and control information from another device.

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.
