First Claim
Patent Images
1. A base station comprising:
- means for transmitting at an output power level a plurality of assigned channels and at least one global channel;
means for monitoring said output power level;
closed-loop forward power control means for individually controlling the power level of said assigned channels; and
global channel power control means for controlling the power level of said global channel, responsive to said output power level;
said global channel power control means comprising a processor, responsive to said monitoring means, which calculates a desired power level for said global channel and adjusts the power of said global channel in response thereto;
wherein the power of said global channel is adjusted in response to all net changes in the total power of said assigned channels.

Abstract
A system which dynamically adjusts the power of signals transmitted from a wireless base station over global channels to minimize spillover to other communication cells monitors the total transmit power of the base station and dynamically adjusts the global channel transmit power as a function of the total transmit power of the base station as measured at the base station.

12. A method for controlling the power of global channels transmitted from a base station comprising:
-
transmitting at an output power level a plurality of assigned channels and at least one global channel; monitoring said output power level; individually controlling the power level of said assigned channels using closed-loop forward power control; and controlling the power level of said global channel by calculating a desired power level based upon said monitoring step, and adjusting the power of said global channel in response thereto;
wherein the power of said global channel is adjusted in response to all net chances in the total power of said assigned channels. - View Dependent Claims (13, 14, 15, 16, 17, 18)
