1. A method for conducting a pilot signal search in a wireless communications network, comprising:
- determining the location of a mobile station within the network;
utilizing said location of said mobile station, search window sizes, and parameter information to minimize the search time required for searching all the pilots identified in a pilot set; and
searching for all pilots in said pilot set.

Abstract
A method and apparatus for conducting a pilot signal search in a wireless communications network. The location of a mobile is determined within the network. This location is then used in determining search window sizes and other search parameter information that is used to search all pilot signals identified in a designated pilot signal set. Search window size is also determined based upon the location of the mobile and another component related to multipath effects for a transmitted pilot signal.
