US Patent:

20060209721, Sep 21, 2006

Filed:

Jun 21, 2005

Appl. No.:

11/158584

Inventors:

Murat Mese - Rancho Palos Verdes CA, US
Arak Sutivong - San Diego CA, US
David Julian - San Diego CA, US

International Classification:

H04L 12/28
H04Q 7/00

US Classification:

370254000, 370329000

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, recieve 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.
