Methods and apparatus for determining, communicating and using information which can be used for interference control purposes
First Claim
1. A method of operating a wireless terminal comprising:
- receive a first signal from a first base station with which the wireless terminal has a connection;
receive a second signal from a second base station;
measure the power of the first received signal;
measure the power of the second received signal; and
transmit a report indicating a ratio of a first value to a second value, the first and second values being a function of the measured power of the first received signal and the measured power of the second received signal, respectively.

Abstract
Methods and apparatus for collecting, measuring, reporting and/or using information which can be used for interference control purposes. Wireless terminals measure signals transmitted from one or more base stations, e.g., base station sector transmitters. The measured signals may be, e.g., beacon signals and/or pilot signals. From the measured signals, the wireless terminal generates one or more gain ratios which provide information about the relative gain of the communications channels from different base station sectors to the wireless terminal. This information represents interference information since it provides information about the signal interference that will be caused by transmissions from other base station sectors relative to transmissions made by the base station sector to which the wireless terminal is attached. Based on the signal energy measurements and relative gains generated from the energy measures, reports are generated in accordance with the invention and sent to one or more base stations.
