Abstract:
A base station comprising:a baseband processing unit for generating a plurality of baseband information signals; a plurality of transmux devices each of which is associated with a different carrier frequency and which each receive one of said plurality of baseband information signals and upconvert said plurality of baseband information signals to their respective channel frequencies; and at least one attenuator associated with each of said plurality of transmux devices for selectively attenuating each of said upconverted baseband information signals, wherein each of said attenuators can be set to different values to provide downlink power control, wherein the processing unit comprises instructions for: generating a plurality of baseband information signals; upconverting said plurality of baseband information signals to their respective channel frequencies; and selectively attenuating each of said upconverted baseband information signals using a plurality of attenuators, wherein each of said attenuators can be set to different values to provide downlink power control; and transmitting in a first cell sector during a first timeslot using a first power level; transmitting in a second cell sector during a second timeslot using a second power level; and transmitting in said first cell sector during a first part of said second timeslot using said first power level.
