Abstract: Provided are a method in which a source distribution unit (DU) of a base station stops transmitting data to a user equipment (UE) in a wireless communication system, and an apparatus supporting the method. The method may include: receiving, from a central unit (CU) of the base station, a message indicating to stop transmitting data to the UE; and stopping transmitting data to the UE, upon receiving the message from the CU of the base station.

Abstract: Disclosed are a method for transmitting an MBMS interest indication message and a device supporting same. A method for transmitting an MBMS interest indication message, according to an embodiment of the present invention, comprises the steps of: deciding a coverage enhancement (CE) level of a terminal in a wireless communication system; receiving CE level information of an MBMS service of interest; comparing the decided CE level of the terminal and the received CE level information of the MBMS service and thus determining whether or not the MBMS service can be received; and, if it is determined that the MBMS service can be received, transmitting to a base station an MBMS interest indication message comprising information about an MBMS frequency of interest or an MBMS service of interest.

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: 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: 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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling of a RRC connection request message of a remote UE by a Relay UE in wireless communication system, the method comprising: receiving NAS information for establishing RRC connection of the remote UE from a remote UE which is configured to connect to the relay UE via sidelink in state that both of the remote UE and the relay UE are in RRC idle states, transmitting a RRC connection request message with an identity of the remote UE to an eNB, when a NAS layer of the relay UE triggers only service request for the remote UE; transmitting a RRC connection setup message for the remote UE to the remote UE; and transmitting a RRC connection setup complete message with the received NAS information of the remoter UE to the eNB.
