Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects. a user equipment (UE) may transmit a first message of a four-step random access channel (RACH) procedure to a base station. The UE may receive a second message of the four-step RACH procedure. The UE may transmit a third message of the four-step RACH procedure. The UE may determine that the third message was not successfully decoded by the base station. The UE may retransmit the third message based at least in part on applying a power boosting algorithm to increase an uplink transmission power. wherein the power boosting algorithm is applied based at least in part on a power offset between the third message and the first message satisfying a threshold and a transmit power control (TPC) command not being received from the base station. Numerous other aspects are described.
