Methods and apparatus for determining, communicating and using information which can be used for interference control

摘要

A wireless terminal receives a broadcast uplink interference report request conveying a requested report type and/or a locally unique base station identifier. The wireless terminal receives and measures broadcast reference signals, e.g., beacon and/or pilot signals, transmitted from a plurality of base station attachment points. Specific type interference reports relate a current serving connection base station attachment point to a selected base station attachment point corresponding to the received base station identifier. Generic type interference reports relate a current serving base station connection attachment point to other unspecified base station attachment points whose broadcast reference signals have been detected by the wireless terminal. Sub-types of generic reports include summation function and maximum function reports. Timing information is sometimes used to determine report sub-type and/or sector type of the selected attachment point. The wireless terminal generates the requested report and transmits it to the current connection attachment point.

主权项

1. A method of operating a wireless terminal comprising:
receiving, from a first attachment point with which said wireless terminal has a connection, a request for a specific interference report that communicates information on interference to said first attachment point, at said wireless terminal, specifically from a second interfering attachment point, said request for a specific interference report including base station identification information identifying one of a plurality of interfering base stations, said identified one of the plurality of interfering base stations being a base station at which the second interfering attachment point is located; receiving a first signal from said first attachment point; performing a first measurement on the received first signal; receiving a second signal from said second interfering attachment point; performing a second measurement on the received second signal; generating said specific interference report based on the first measurement of the received first signal and the second measurement of the received second signal; and transmitting the generated specific interference report.
