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.

Abstract: Systems, methods, apparatuses, and computer program products for reusing sidelink resources associated with dropped configured grant are provided. For example, a method can include receiving, with a first device, a sidelink grant from a network node for transmission to a third device; receiving a coordination request from a second device; determining whether to transmit to the third device using at least one resource associated with the sidelink grant; and determining whether to forward the at least one resource associated with the sidelink grant to the second device with a response to the coordination request.

Abstract: A method, apparatus and computer program product are provided for efficiently activating or deactivating user equipment. An example method includes receiving a deactivation request comprising one or more identifiers for one or more user equipment or one or more user equipment groups, determining which one or more user equipment or user equipment groups are impacted by the deactivation request and causing a suspend request to be transmitted to the one or more user equipment or user equipment groups that are impacted. Another example method is provided for receiving an activation request comprising one or more identifiers for one or more user equipment or one or more user equipment groups, determining which one or more user equipment or user equipment groups are impacted by the activation request, and causing a notice to be transmitted to the one or more user equipment or user equipment groups that are impacted.

Abstract: The method includes a processor of a first UE receiving first group information for a user group with user-device members, the first group information including information for mapping a sidelink channel resource for each of the user-device members to perform a groupcast communication over sidelink for the user group, the first UE being a user-device member of the user group. The method further includes receiving second group information for transmitting data within the groupcast communication, the second group information including updated information of the first group information that is specific to the first UE, initiating a first transmission process to transmit a first data block to the user group for the groupcast communication over the sidelink based on the first group information, and adapting the first transmission process of the first data block based on the second group information.

Abstract: An SL UE that detects a resource conflict associated with a transmitting UE may be able to indicate this resource conflict by transmitting inter-UE coordination information over a PSFCH resource determined based on a group member ID of the transmitting UE. This may be different from transmitting HARQ feedback via a PSFCH resource determined based on a group member ID of the detecting UE.

Abstract: Systems, methods, apparatuses, and computer program products for sidelink (SL) based multi-hop UE relaying, for example, to support tracking applications are provided. One method may include determining, at a user equipment (UE), to which tier of a sidelink (SL) based multi-hop user equipment (UE) relaying the user equipment (UE) belongs. The method may also include determining at least a relaying mode and arrangement of transmit and receive occasions for sidelink (SL) transmission and reception in dependence on the determined tier that the user equipment (UE) belongs, and performing, on the determined transmit and receive occasions, transmit and receive operations for the sidelink (SL) based multi-hop user equipment (UE) relaying based on the determined relaying mode and arrangement.
