Abstract: Triangular inter-user equipment coordination for new radio sidelink communications is provided. An exemplary apparatus may include at least one processor, and at least one memory. The memory stores instructions that, when executed by the processor, may cause the apparatus at least to receive, from a first device, a request of inter-user equipment coordination. The apparatus may also be caused to determine at least one second device to which to forward the request. The apparatus may also be caused to modify the request and forward the modified request to the at least one second device for the second device to provide a response to the request to the first device. The request may be modified by an indication related to the forwarding to the at least one second device.

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: Systems, methods, apparatuses, and computer program products for resource collision avoidance in sidelink for discontinuous reception (DRX). For example, certain embodiments described herein may help to ensure a reliable method for reaching a power saving solution for an autonomous resource selection, using a fixed set of rules, based on concepts of sub-pools. This may be done by indicating a set of resources to user equipment (UEs), which may be used for sensing and selection. The resources provided may be offset by a number of resources selected at random, based on UE-identifier, or as otherwise indicated.

Abstract: Systems, methods, apparatuses, and computer program products for monitoring PC5 interface to radio resource control (PC5-RRC) configuration procedure, e.g., in new radio (NR) sidelink (SL) mode 1, are provided. One method may include configuring a SL user equipment (UE) with behaviors for handling and monitoring PC5-RRC procedures and one or more related timers by taking into account a status of an interface between the SL UE and the network node.
