The user equipment includes a processor configured to receive a broadcast message, the broadcast message including RACH parameters. The processor transmits a first message following receipt of the broadcast message. The processor receives a second message. The processor transmits a third message, the third message including power settings based on a successful transmission of the first message, and receives a fourth message, the fourth message including contention resolution information that adjusts the RACH parameters. The user equipment decodes RACH parameters and the contention information to obtain decoded RACH parameters, and adjusts an initial transmit power of the user equipment to be a first transmit power based on the decoded RACH parameters.
