Abstract

An access terminal defines a search window based on a distance between access points. Here, a first one of the access points may comprise a macro access point from which the access terminal acquires timing. The search window may be used to monitor for pilot signals from a second one of the access points. For example, the second access point may comprise a femto node that provides relatively small area coverage. In some aspects the definition of the search window may involve adjusting (e.g., advancing) a center of a search window based on the distance between the access points. In addition, the access terminal may employ a smaller search window when it is searching for pilot signals from a femto node as compared to when it is searching for pilot signals from a macro access point.

Description

[0001] Claiming Priority Based on 35 U.S.C.§.119 [0002] This patent application claims priority to US Provisional Patent Application No. 60 / 986,953, filed November 9, 2007, assigned Attorney Docket No. 080218P1, the disclosure of which is incorporated herein by reference. technical field [0003] In general, this application relates to wireless communications, and in particular, but not by way of limitation, this application relates to defining search windows. Background technique [0004] Wireless communication systems are widely deployed in order to provide various types of communications (eg, voice, data, multimedia services, etc.) to multiple users. With the rapidly increasing demand for high-speed and multimedia data services, there is the challenge of realizing efficient and robust communication systems with improved performance. [0005] To supplement conventional mobile phone network base stations (eg, macro cells), small-coverage base stations can be deployed (eg...
