PROBLEM TO BE SOLVED: To provide a wireless data communication system that maintains synchronization between a base station and a mobile station even when stop of transmission from the base station continues for a long time during DOX control. SOLUTION: The base station transmits data at any time when a buffer of the base station stores a plurality of transmission data and when the buffer stores one transmission data only, the base station sets a DOX flag and outputs the flag with the transmission data. The base station stops transmission output when no transmission data is stored in the buffer. When the data are again given to the buffer 11, the base station generates output restart notice data 16, clears the DOX flag and transmits the data. Assuming that adjustment of synchronization between the mobile station and the base station is difficult only with the output restart notice data 16 when the output stop from the base station continues for a long time, the base station generates idle data 17 and outputs the data 17 is predetermined timing. The mobile station receives the idle data to adjust the synchronization between the two stations. |
