When carrying out CDMA/TDD-based data communications between a base station apparatus and mobile station apparatus, the base station apparatus and mobile station apparatus carry out VOX control turning ON/OFF transmission operation according to the presence/absence of transmission data and if transmission on the base station transmitting side is OFF the mobile station receiving side receives channels being sent all the time from the base station apparatus, performing open-loop transmission power control, and if transmission on the mobile station transmitting side is OFF the mobile station apparatus transmits dummy slots with small transmission power while the base station receiving side receives the dummy slots, performing transmission space diversity.
