Abstract: Example embodiments of the present disclosure relate to a device, method, apparatus and computer readable storage medium for hybrid automatic repeat request (HARQ) feedback for adjustment of contention window size for communication in an unlicensed band. In example embodiments, if it is determined that a failure of transmission in an unlicensed occurs, the device determines a cause of the failure of the transmission is determined based on received information associated with a transmission collision. Then, the device adjusts a size of a contention window for a listen-before-talk procedure.

Abstract: An apparatus may be configured to: connect to a first base station with one of: a direct connection, or an indirect connection via a first relay user equipment; determine at least one second relay user equipment for receiving a reconfiguration message for path switching to a second base station; establish a sidelink connection with the at least one second relay user equipment; and receive, via the sidelink connection from the at least one second relay user equipment, the reconfiguration message for the path switching to the second base station. An apparatus may be configured to: receive, from a second base station, a reconfiguration message, wherein the received reconfiguration message comprises a reconfiguration message for a remote user equipment; establish a sidelink connection with the remote user equipment; and forward, to the remote user equipment, the reconfiguration message for the remote user equipment.

Abstract: Methods, apparatuses, and computer program products are provided to facilitate relay discovery, selection, and/or reselection for U2N relaying over SL utilizing a service-continuity indication provided via one or more solicitation messages from a remote UE to at least one relay UE. In some embodiments, a serving network may provide identification of the at least one relay UE via a remote configuration for the remote UE. In some embodiments, the serving network may provide identification of the at least one relay UE via a response message transmitted to the remote UE via SL. In some embodiments, the remote UE may prioritize one or more potential relay UE candidates identified by the serving network.
