Configurations for sidelink beam management

A method for wireless communications at a second user equipment (UE), comprising:

• transmitting, to a network device or a first UE, a report that indicates beam sweeping capabilities of the second UE for a sidelink communications link between the first UE and the second UE, the report including an indication of a relative orientation of multiple antenna panels of the second UE;
• receiving, as part of a sidelink beam sweeping procedure for the sidelink communications link between the first UE and the second UE, one or more reference signals from the first UE via a set of reception beams over time-frequency resources of the sidelink communications link in accordance with a configuration for the sidelink beam sweeping procedure and based at least in part on the beam sweeping capabilities of the second UE, the configuration indicating the time-frequency resources for the sidelink beam sweeping procedure;
• and
• transmitting, to the network device or the first UE, a measurement report of the sidelink beam sweeping procedure based at least in part on the one or more reference signals, wherein the measurement report comprises measurement information associated with the one or more reference signals.

An apparatus for wireless communications at a first user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit a report that indicates beam sweeping capabilities of the first UE for a sidelink communications link between the first UE and a second UE;
• receive a signal indicating a configuration for a sidelink beam sweeping procedure for the sidelink communications link between the first UE and the second UE based at least in part on the beam sweeping capabilities of the first UE, the configuration indicating time-frequency resources for a set of transmission beams of the first UE for the sidelink beam sweeping procedure;
• and
• perform the sidelink beam sweeping procedure with the second UE using the set of transmission beams and the indicated time-frequency resources based at least in part on the configuration.
