In a situation where traffic changes abruptly, the phase of the control signal changes at high speed, and the mobile station may not be able to follow the change, or the stability of system control may decrease. As a method to cope with this, a predetermined time (x seconds) is waited before adjusting the phase of the control signal according to the number of used channels and returning to the determination of the number of used channels again.
