AI Technical Summary

Problems solved by technology

While reducing the transmit power of a beacon can reduce this interference, this reduction in transmit power will also reduce the coverage associated with that beacon
This in turn prevents the access terminal from discovering the presence of the small-coverage access point

Abstract

An access point generates beacons at different power levels at different times to provide an acceptable tradeoff between coverage area associated with the beacons and outage experienced at nearby access terminals. For example, a femto access point may transmit beacons at a relatively low power for a relatively long period of time to reduce interference at nearby access terminals that are being served by a macro access point. The femto access point may then transmit beacons at a relatively high power for a relatively short period of time to enable nearby access terminals to receive the beacons. Also, a given transmit chain may be used to provide frequency hopping of high and low power beacons.

Description

[0001] claim priority [0002] This application claims the benefit and priority of commonly owned U.S. Provisional Patent Application No. 61 / 090,548, Attorney Docket No. 082470P1, filed August 20, 2008, the disclosure of which is hereby incorporated by reference content. technical field [0003] The present application relates generally to wireless communications, and more particularly, but not exclusively, to generating communication beacons. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communications to multiple users. For example, voice, data, multimedia services, etc. may be provided to a user's access terminal (eg, a cellular telephone). With the rapidly increasing demand for high-speed and multimedia data services, there is a challenge to realize an efficient and stable communication system with enhanced performance. [0005] To supplement conventional mobile phone network access points (eg, macro base ...
