Abstract: Certain aspects of the disclosure provide techniques for random access channel (RACH) power control, including for message (MSGA) transmission by a user equipment (UE) for two-step RACH procedure. Certain aspects provide a method for wireless communication generally including determining a transmit power for transmitting a first message to a base station (BS) as part of a two-step RACH procedure, the first message comprising a first part and a second part. Determining the transmit power comprises determining a first transmit power for transmitting the first part based on a first function having parameters including a power ramping counter and a power ramping step. Determining the transmit power further comprises determining a second transmit power for transmitting the second part based on a second function having parameters including the power ramping counter and the power ramping step. The method further includes incrementing the power ramping counter based on transmitting the first message.

Abstract: Disclosed are techniques for determining a beam-specific timing advance for Round-Trip Time (RTT) estimation. In an aspect, a first node receives a plurality of beams transmitted by a second node on a wireless channel, selects a first beam from the plurality of beams for transmitting a timing response, determines a timing statistic, a timing difference, and a timing advance for the first beam, wherein the timing difference comprises a difference between the timing statistic and an earliest time of arrival of the plurality of beams, and wherein the timing advance comprises a multiple of the timing difference, and transmits the timing response for the first beam to the second node on the wireless channel, wherein the first node transmits the timing response after a time delay from the timing statistic of the first beam, wherein the time delay comprises a difference between a predetermined time delay and the timing advance.
