FIG. 7 illustrates an example 700 of sidelink communication resource signaling, in accordance with various aspects of the present disclosure. As shown in FIG. 7, example 700 includes one or more BSs 110, a source UE 120 that is to transmit a sidelink communication, and a target UE 120 that is to receive the target communication. For example, a single BS 110 may be a serving cell for both source UE 120 and target UE 120. Alternatively, a first BS 110 may be a serving cell for source UE 120 and may communicate via a backhaul link with a second BS 110 that is a serving cell for target UE 120.
As further shown in FIG. 7, and by reference number 710, BS 110 may receive a request for a sidelink grant. For example, when source UE 120 has data or control information queued for transmission to target UE 120, source UE 120 may request a grant for sidelink resources to transmit the data or control information to target UE 120 as a sidelink communication. Additionally, or alternatively, BS 110 may transmit or configure a periodic or semi-persistent sidelink grant to source UE 120 to enable source UE 120 to transmit to target UE 120 on the sidelink.
