ABSTRACT:
A radio communication system in which each frame having an imbalanced transmission speed is time-divided to a low speed transmission area and to a high speed transmission area according to a specified ratio in the time domain. An upload signal as a first-directional signal and a download signal as a second-directional signal are allocated to the low speed transmission area and to the high speed transmission area respectively. In a case where a high speed transmission request is issued from a personal station (PS) to a base station (BS), the order of the upload signal and that of the download signal is exchanged in the time domain within one frame, so that the download signal and the upload signal are allocated to the low speed transmission area and the high speed transmission area respectively.
