Global channel power control to minimize spillover in a wireless communication environment
First Claim
Patent Images
1. A transmitter for use in a spread spectrum wireless communication system, the transmitter transmitting a plurality of channels within a shared spectrum including a global channel, the transmitter comprising:
- for each channel, a modem for producing a signal associated with that channel;
a signal combiner for combining the produced channel signals as a combined signal;
a radio frequency transmitter for transmitting the combined signal; and
a global channel power control processor for determining a desired transmit power level of the global channel based on in part a transmit power level of the combined signal; and
a power controller associated with the global channel for adjusting a transmit power level of the global channel to be the determined global channel transmit power level.

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.
