Abstract: A method and apparatus for supporting a fast link recovery and link status reporting in a wireless communication system is provided. When a node detects a radio link problem on a wireless backhaul link between integrated access and backhaul (IAB) nodes from the node to a donor node of an TAB network, the node reselects a cell operated by a gNB which is directly connected to the donor node, and performs a random access procedure towards the cell operated by the gNB to report information on the radio link problem to the cell. The donor node may establish a new path for the node.

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 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: A method for transmitting feedback information by a remote user equipment (remote UE) in a further enhancement D2D (FeD2D) environment comprises a step of transmitting feedback information on a plurality of relay user equipments (relay UEs) which have been linked to the remote UE through a PC5 interface, wherein the feedback information is transmitted via a separate feedback channel set by a network rather than the PC5 interface, and the feedback information may be transmitted to the plurality of relay UEs in a multicast form.

Abstract: Disclosed are a method for performing V2X communication in a wireless communication system and an apparatus for the same. Specifically, a method for performing vehicle-to-everything (V2X) communication by a user equipment (UE) in a wireless communication system includes: receiving a transmission request of a V2X message of a V2X service identified by a V2X service identifier from an upper layer by using V2X communication through a PC5 interface, the transmission request including the V2X message and the V2X service identifier; requesting or selecting a resource for the V2X communication through the PC5 interface to a base station based on whether the UE is serviced by an evolved universal terrestrial radio access network (E-UTRAN) for the V2X communication; and transmitting the V2X message through the PC5 interface by transferring the V2X me3ssage to a lower layer, and when mapping between the V2X service identifier and a transmission parameter is configured, the transmission parameter associated with the V2X service identifier may be transferred to the lower layer together with the V2X message.

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 local id identifying a remote UE in a relay UE in wireless communication system, the method comprising: generating a local ID identifying a remote UE of which transmits/receives data to/from a eNB via the relay UE, wherein the generated local ID is derived from RAT specific ID which is acquired during discovery procedure and linking process between the remote UE and the relay UE; receiving RRC connection request message from the remote UE; and transmitting the RRC connection request message for the remote UE using the generating local ID to the eNB.

Abstract: In the present invention, a user equipment (UE) receives physical random access channel (PRACH) configuration information. The UE determines a part of PRACH resources among PRACH resources configured based on the PRACH configuration information, if a random access (RA) procedure is triggered. The UE performs the RA procedure using only the determined part of the PRACH resources. The PRACH configuration information includes a periodicity value N, expressed in number of configured PRACH resources. The determined part of PRACH resources are every N-th configured PRACH resource, starting from a specific PRACH resource for the RA procedure, among the PRACH resources configured based on the PRACH configuration information.
