Uplink transmit power control during random access procedures

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

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• determine a receive beamforming gain for a receive beam of the UE;
• determine a transmit power for an uplink random access transmission based at least in part on adding or subtracting a power offset and an estimated path loss, wherein the power offset is proportional to a beamforming gain difference between the determined transmit beamforming gain and the determined receive beamforming gain;
• and
• transmit the uplink random access transmission using the determined transmit power.

An apparatus for wireless communication at a base station, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• identify a user equipment (UE), the UE having a transmit beam and a receive beam;
• and
• transmit an instruction to the UE for the UE to use to adjust a transmit power for an uplink random access transmission of the UE based at least in part on a power offset that is proportional to a beamforming gain difference between a transmit beamforming gain for the transmit beam of the UE and a receive beamforming gain for the receive beam of the UE, wherein the instruction comprises an indication for the UE to add or subtract the power offset when calculating the transmit power.
