ABSTRACT:
In a system comprising a first base station (B1) assigned with a control channel frequency, a counterpart mobile station (P1) of the first base station, and a second base station (B2) adjacent to the first base station and assigned with the control channel frequency, the first base station comprises a control information transmitting portion (1, 5) for intermittently transmitting control information signals through the control channel frequency to the counterpart mobile station with a time duration left between two adjacent ones of the control information signals. A time duration determining portion (2, 14) randomly determines a following time duration between current and following control information signals so that the following time duration randomly varies from a previous time duration previously determined between the current and previous control information signals. A transmission control portion (12) controls the control information transmitting portion to transmit the current control information signal through the control channel frequency to the counterpart mobile station with the following time duration inserted in the current control information signal. The counterpart mobile station comprises a control information receiving portion (3) for selectively receiving the current control information signal and the following time duration inserted in the current control information signal through the control channel frequency in accordance with the previous time duration previously received with the previous time duration included in the previous control information signal.
