MOBILE STATION APPARATUS AND TRANSMISSION POWER CONTROL METHOD

摘要

A mobile station (14) transmits a connection request signal (TCCH) to a base station (12) (S102), and detects whether or not a connection response signal (SCCH) is received from the base station (12) within a predetermined amount of time. If the connection response signal (SCCH) is not received within the predetermined amount of time, the number of subcarriers used in transmission of wireless signals to the base station (12) is reduced and the transmission power per subcarrier is increased by the amount of power corresponding to this reduction (S104), and the connection request signal (TCCH) is resent (S106).
