Abstract
Radio communication systems employing time division multiple access (TDMA) on several frequency channels are disclosed. The base station transmitting powers can be reduced when communicating with nearby mobile stations while still permitting the base station to employ a constant transmitting power in all time slots. This can be accomplished by, for example, grouping mobile stations having similar transmit power requirements together and allocating such groups to time slots on a same frequency. In this way, the base station can transmit at a constant power for each time slot on a frequency and provide acceptable communication quality, but without unnecessarily wasting base station transmitter power by transmitting to mobile stations having widely divergent power requirements.
