A system adapts power for minimizing the total amount of transmitted power in a wireless communications network. A transmit station transmits a communications signal requesting a response from receiving mobile stations. A plurality of the mobile stations receives the communications signal and each evaluates the signal reception, such as the signal-to-noise ratio or transmitted power. Each mobile station responds by transmitting a communications signal back to the transmit station in a specific time slot as a function of the signal reception to allow the transmit station to adapt its power based on the time slot of the communications signals received from respective mobile stations. This minimizes the total amount of power transmitted by the wireless communications network.
