Abstract

Certain aspects of the present disclosure provide techniques for wireless communication. An example method includes receiving configuration information indicating one or more configurations for an initial sidelink beamforming procedure involving one or more transmit beams, each associated with a respective antenna panel of a first UE, and performing the initial sidelink beamforming procedure based on the configuration information. Performing the initial sidelink beamforming procedure includes transmitting at least a first beamforming burst, comprising transmitting each beamforming transmission of one or more beamforming transmissions using a different respective transmit beam of the one or more transmit beams of one or more antenna panels of a first UE, monitoring for at least one response message from a second UE responding to at least one of the one or more beamforming transmissions, and taking one or more actions based on the monitoring.
