Beam based power control for sidelink

A method of wireless communication at a first user equipment (UE), comprising:

• initiating a beam pairing with a second UE, the first UE being a transmitting UE and the second UE being a receiving UE;
• identifying a sidelink beam from a plurality of sidelink beams and at least one power control parameter for sidelink communication with the second UE, wherein different sidelink beams use different power control parameters;
• receiving, from the second UE, a reference signal received power (RSRP) report comprising a CSI-RS resource indicator (CRI) and an associated RSRP, wherein a sidelink path loss is calculated based on the RSRP report;
• and
• communicating with the second UE via a selected sidelink beam and the at least one power control parameter.

An apparatus for wireless communication at a second user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive a request for initiating a beam pairing with a first UE, the first UE being a transmitting UE and the second UE being a receiving UE;
• transmit or receiving one or more sidelink reference signals to determine a sidelink beam and associated power control parameters for sidelink communication with the first UE, wherein different sidelink beams use different power control parameters;
• transmit, to the first UE, a reference signal received power (RSRP) report comprising a CSI-RS resource indicator (CRI) and an associated RSRP, wherein a sidelink path loss is calculated based on the RSRP report;
• and
• communicate with the first UE via the sidelink beam and the associated power control parameters.
