PROBLEM TO BE SOLVED: To provide a communication system wherein a full rate data channel for circuit switched communications, two half rate data channels and four quarter rate data channels comprise respective operation modes. SOLUTION: The communication system wherein a first station is capable of communicating with a second station over a wireless channel, data are carried over the wireless channel in superframes, each superframe is composed of a plurality of frames and each frame is composed of a plurality of time slots, has a fist mode of operation in which a full rate data channel for circuit switched communications is defined by the allocation to that data channel of corresponding time slots is each frame, and a second mode of operation in which two half rate data channels for packet switched communications are defined by the allocation to each of those data channels of an equal number of corresponding time slots of frames in each superframe.
