1. A method of communications at a user equipment (UE), comprising:
receiving, by the UE and in a direction of a sidelink transmission beam, a plurality of synchronization reference signals from a base station, wherein the sidelink transmission beam is configured at the UE for transmitting sidelink communications to a second UE;
measuring a respective Reference Signal Received Power (RSRP) value of each of the plurality of synchronization reference signals;
determining a highest RSRP value from each of the respective RSRP values;
calculating a downlink pathloss associated with a sidelink open loop power control based on the highest RSRP value; and
determining a transmit power of communication with the second UE on a sidelink based on a minimum between a sum of a desired received signal power at the second UE and the downlink pathloss and a sum of the desired received signal power at the second UE and a pathloss between the UE and the second UE.
