Abstract: A method for performing a sidelink communication through a terminal-to-network relay operation is disclosed. The method performed by a first user equipment (UE) includes transmitting, to a base station, a control message including indication information indicating whether a radio access technology (RAT) type of a radio interface section with a second UE is a 3GPP access or a non-3GPP access; receiving, from the base station, a radio resource for transmitting and receiving a signal with the second UE through the radio interface section; and transmitting and receiving the signal with the second UE based on the received radio resource.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing sidelink transmission prioritized over the uplink transmission in wireless communication system, the method comprising: generating uplink data and sidelink data to be transmitted in a subframe; determining that uplink transmission is denied in the subframe if sidelink transmission is prioritized over the uplink transmission; and transmitting the sidelink data in the subframe where the uplink transmission is denied, wherein the subframe is one of subframes allowed for denial of the uplink transmission during a validity period.

Abstract: Disclosed are a method for performing V2X communication in a wireless communication system and an apparatus therefor. Specifically, a method for supporting, by a base station, a user equipment (UE) to perform vehicle-to-everything (V2X) communication with a vehicle through a PC5 interface in a wireless communication system may include: receiving a sidelink UE information message for requesting resource allocation for the V2X communication through the PC5 interface from a UE in a limited service state; checking whether the UE has a capability to use the V2X communication with an emergency packet data network (PDN) connection or whether the UE is authorized to perform the V2X communication; and allocating a resource for the V2X communication when the UE has the capability to use the V2X communication with the emergency (PDN) connection or the UE is authorized to perform the V2X communication.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing management of different IDs in a Relay UE in wireless communication system, the method comprising: receiving information for mapping table between a set of first identifiers (IDs) and a set of second IDs from a network; receiving a UL packet, which is to be forwarded to the network, without a second ID from the remote UE identified by a first ID associated with the second ID according to the mapping table; adding the second ID associated with the first ID to the UL packet; and transmitting the UL packet with second ID to the network. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: A method for performing vehicle-to-everything (V2X) communication in a wireless communication system and a device for same are disclosed. Particularly, a method for a user equipment (UE) performing V2X communication by means of a PC5 interface in a wireless communication system comprises the steps of: receiving from an upper layer a request for transmitting a V2X message; requesting radio resources, for V2X communication by means of a PC5 interface, to a base station or selecting radio resources for V2X communication by means of the PC5 interface; and performing transmission of V2X communication by means of the PC5 interface, wherein, if a UE has emergency packet data network (PDN) connection, an indication, indicating that transmission by means of the emergency PDN connection is a higher priority than the V2X communication by means of the PC5 interface, can be transmitted from the upper layer.

Abstract: A method for performing, by a relay user equipment (UE), a buffer status reporting (BSR) procedure in a wireless communication system is discussed. The method includes receiving data to be relayed from a remote UE via sidelink; trigger a BSR or a sidelink BSR for the data to be relayed; and transmit the BSR or the sidelink BSR to a network.

Abstract: A method and apparatus for reselecting a path for an integrated access and backhaul (IAB) relaying in a wireless communication system is provided. An IAB node configures a criteria of path reselection among multiple nodes, receives information from the multiple nodes, and performs the path reselection based on the criteria by using the information received from the multiple nodes and cell quality of the multiple nodes.

Abstract: Suggested is a novel condition for a media access control (MAC) entity in user equipment (UE) reselecting a sidelink resource in a wireless communication system. The MAC entity of the UE can reselect a sidelink resource when a configured sidelink grant does not satisfy a latency requirement according to ProSe per-packet priority (PPPP). More particularly, configuration is performed by an upper layer so that the MAC entity transmits on the basis of sensing using a resource pool; the MAC entity selects generation of a configured sidelink grant corresponding to transmission of a plurality of MAC protocol data units (PDU); and when data is available in a sidelink traffic channel (STCH) and the configured sidelink grant does not satisfy the latency requirement according to the PPPP, a sidelink resource is reselected.

Abstract: Provided are a method for a terminal for requesting a system information block (SIB), and an apparatus for supporting the method in a wireless communication system. The method may comprise the steps of: receiving, from a radio access network (RAN), an SIB list comprising one or more SIBs supported by a cell; receiving, from the RAN, SIB broadcast information indicating whether the SIB supported by the cell is broadcast in a broadcast control channel (BCCH) section; detecting an omitted SIB on the basis of the SIB list and SIB broadcast information; and requesting the omitted SIB from the RAN.

Abstract: Provided are a timer-based method for a terminal for requesting a system information block (SIB), and an apparatus for supporting the method in a wireless communication system. The method may comprise the steps of: determining whether an essential SIB has been omitted from a cell; requesting the omitted essential SIB from an RAN if the essential SIB is determined to have been omitted from the cell; starting a system information request timer; and re-requesting the omitted essential SIB from the RAN when the system information request timer expires.
