Techniques for configuring beam-specific feedback for sidelink communications

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a first and second directional beam for communicating with one or more UEs on a first and second sidelink communication link. In some cases, the UE may identify a first sidelink feedback configuration for the first directional beam. The UE may also identify a second sidelink feedback configuration for the second directional beam, where the second sidelink configuration may be different from the first sidelink feedback configuration. In some examples, the UE may transmit an indication of the first sidelink feedback configuration and the second sidelink feedback configuration to the one or more UEs, where received feedback for sidelink messages sent over the directional beams may be based on the different sidelink feedback configurations. In addition, feedback resources may be based on a beam identifier of a beam used to transmit an initial sidelink message.
