Abstract
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.
