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.

A radio communication system comprising: a plurality of frequencies for transmission of communication signals; a plurality of time slots on each frequency; a plurality of first stations which transmit and receive communication signals on the time slots; and at least one second station which assigns time slots on a first frequency to first stations which are to be communicated with by employing highest second station transmitter power levels and which assigns time slots on a second frequency to first stations which are to be communicated with by employing second station transmitter power levels which are lower than said highest second station transmitter power levels, wherein each time slot transmitted on said first frequency is transmitted at a higher power level than each time slot transmitted on said second frequency.
