Interference control in a wireless communication system
First Claim
1. A method for interference control, the method being implemented by a sector, the method comprising:
- obtaining a measured interference that represents an estimate of interference observed at the sector due to transmissions from terminals in other sectors;
generating an interference report based on the measured interference, wherein the interference report conveys the measured interference for the sector relative to multiple interference thresholds; and
broadcasting the interference report to the terminals in the other sectors.

Abstract
For interference control, a sector m estimates interference observed from terminals in neighbor sectors and obtains an interference estimate. Sector m may generate an over-the-air (OTA) other-sector interference (OSI) report and/or an inter-sector (IS) OSI report based on the interference estimate. Sector m may broadcast the OTA OSI report to the terminals in the neighbor sectors. These terminals may adjust their transmit powers based on the OTA OSI report. Sector m may send the IS OSI report to the neighbor sectors, receive IS OSI reports from the neighbor sectors, and regulate data transmissions for terminals in sector m based on the received IS OSI reports. Sector m may control admission of terminals to sector m, de-assign admitted terminals, schedule terminals in sector m in a manner to reduce interference to the neighbor sectors, and/or assign the terminals in sector m with traffic channels that cause less interference to the neighbor sectors.
