Abstract
Base station generates a mobile station identifier which indicates a mobile station that a data signal is addressed thereto, and a head slot having a data signal when there is a data signal that has a length to be able to transmitted using one slot of a TDMA radio channel. When there is a data signal that has a length to be not able to transmitted using one slot, base station generates a head slot and continuous slots which contain at least a part of data signal. Base station transmits the head slot by using the starting slot which located at predetermined position every mobile station on the TDMA radio channel, and transmits the continuous slots by using slots which follow the starting slot. Mobile station receives the starting slot, and stops reception if the starting slot is not the head slot. If the starting slot is the head slot, the mobile station judges the mobile station identifier. Furthermore, if the mobile station identifier indicates other mobile station, the mobile station stops reception, on the other hand, if the mobile station identifier indicates itself, the mobile station receives the continuous slot.
