Title:
USER EQUIPMENT SCHEDULING ASSISTANCE FOR MODE 1 SIDELINK COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2024/045108
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may transmit, to a network entity and via an uplink communication link, scheduling assistance information (SAI) that indicates a first set of sidelink resources for sidelink communications by the UE. The UE may determine the first set of sidelink resources based on monitoring for sidelink control information (SCI) from one or more other UEs, based on coordination messages received from one or more other UEs, or both. The UE may receive a scheduling message from the network entity that allocates a second set of sidelink resources for the sidelink communications by the UE based on the first set of sidelink resources indicated via the SAI. The UE may transmit a sidelink message to another UE via the second set of sidelink resources allocated by the scheduling message.
