1. A method comprising:
transmitting, by a wireless device and using a first uplink transmission power, a first message comprising a preamble for a two-step random access procedure and comprising a transport block; and
based on a determination that a response to the first message has not been received within a duration threshold and a determination that a calculated uplink transmission power associated with transmission of a second message exceeds an uplink transmission power threshold, transmitting, using a second uplink transmission power, the second message, wherein the second message comprises a preamble for a four-step random access procedure, and wherein the second uplink transmission power was adjusted from the calculated uplink transmission power to be less than or equal to the uplink transmission power threshold.
