Claim of US Patent No. 10,798,748

1. A user equipment, comprising:a memory with computer-readable instructions; and
at least one first processor configured to read the computer-readable instructions, the at least one first processor being configured to,
receive a broadcast message, the broadcast message including random access channel, RACH, parameters,
transmit a first message following receipt of the broadcast message, the first message including RACH preambles,
receive a second message, the second message being an acknowledgement message that acknowledges receipt of the first message,
transmit a third message based on a successful transmission of the first message, the third message including noise rise information, preamble miss information and power settings for the user equipment, the power settings including power information used to transmit the third message,
receive a fourth message, the fourth message including contention resolution information that adjusts the RACH parameters based on the noise rise information and the preamble miss information,
decode RACH parameters and the contention resolution information to obtain decoded RACH parameters, and
adjust the initial transmit power of the user equipment to be a first transmit power based on the decoded RACH parameters.
