Directional grant for sidelink communication

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

• receiving, from a base station, a grant for time-frequency resources for transmitting to a second UE, the grant including information indicating at least one of a first subset of beams of a set of beams for which the grant applies or a second subset of beams of the set of beams for which the grant applies with a constrained transmission power;
• and
• transmitting, to the second UE, a physical sidelink shared channel (PSSCH) through at least one beam of the first subset of beams based on the received grant, or through at least one beam of the second subset of beams with the constrained transmission power based on the received grant.

A method of wireless communication at a base station (BS), comprising:

• determining, based on transmit directions by a first user equipment (UE) that reduce an interference to other UEs, one of a first subset of beams of a set of beams for a grant or a second subset of beams of the set of beams with a constrained transmission power for the grant;
• and
• transmitting, to the first UE based on the determination, the grant for time-frequency resources for transmitting to a second UE, the grant including information indicating the determined at least one of the first subset of beams of the set of beams for which the grant applies or the second subset of beams of the set of beams for which the grant applies with a constrained transmission power.
