Abstract:
A power control system for controlling transmission power over, communications channels, the system comprising:a first unit having a transmitter, a receiver and a power controller that controls the transmit power of said first unit transmitter;a second unit having a transmitter, a receiver, and means for substantially continuously determining the received signal power needs of the second unit receiver;a forward communications channel between said first unit transmitter and said second unit receiver;a reverse communications channel between said second unit transmitter and said first unit receiver; andmeans for substantially continuously generating reverse channel explicit-power-request commands based on said determination of the received signal power needs of the second unit receiver, said reverse channel explicit-power-request commands representing an absolute power level at which the first unit transmitter should transmit signals over said forward communications channel, wherein said reversed channel explicit-power-request commands communicate said absolute power level in a manner that is substantially independent of the power level at which the first unit transmitter had previously been transmitting with;said second unit transmitter receiving said reverse channel explicit-power-request commands and transmitting said explicit-power-request commands over said reverse communications channel.
