DETERMINING PER SECTOR RECEIVED POWER LEVEL
First Claim
1. A method for determining per sector received power level, comprising:
- receiving an access point pilot signal from each access point;
determining a time-domain channel response from each access point pilot signal;
determining a received digital power level per sector from each access point pilot signal; and
determining a received power level from each access point based on at least the digital power level, wherein the access point represents a sector.

Abstract
At a mobile device, a total received power represents signals received from all access points. In order to calculate an appropriate transmit power for communication with a single access point, a mobile device determines a per sector received power level. The mobile device can ascertain a time-domain channel response from each access point pilot signal, ascertain a received digital power lever per sector from each access point pilot signal and, based in part on the digital power level, calculate a received power level from each access point. A per sector received power level can be utilized to conserve battery power and/or to reduce interference in a wireless communications network.
