Abstract
A mobile station of a two-frequency simplex radio communication system, in which communication between a base station and each mobile station is performed in such a manner that the base station continuously transmits packet data whereas each mobile station transmits burst data. The mobile station includes a radio wave propagation path condition detector for detecting the condition of a radio wave propagation path used for communication, and a communication control circuit which, when it is determined based on the condition of the radio wave propagation path detected by the radio wave propagation path condition detector, that transmission or reception timing cannot be obtained within a predetermined period of time, adaptively selects a transmission mode and notifies the base station of the selected transmission mode so as to receive data which is transmitted from the base station after the notification. This makes it possible to perform communication while maintaining a high transmission efficiency without having to perform a complicated process which needs a large amount of calculations.
