A method and an apparatus for searching code division multiple access pilot signal energies includes limiting a pilot signal window size above a lower limit and only analyzing search result data corresponding to an instructed pilot signal window size. A central processing unit instructs a searcher receiver within a mobile station modem application specific integrated circuit to search for pilot signal energies within an instructed pilot signal search window unless the instructed pilot signal window size is smaller than a pilot signal window size lower limit. In such a case, the pilot signal search window size is artificially designated as the pilot signal window size lower limit to prevent excessive search completion interrupts from over utilizing central processing unit resources. The central processing unit analyzes only the middle search results corresponding to the pilot signal window size as instructed from the base station to maintain the ability of effectively searching pilot signal window sizes smaller than the pilot signal window size lower limit.

A mobile station method of searching for base station pilot signal energy, said method comprising steps of: receiving from a base station an instructed pilot signal window size; defining a pilot signal window size lower limit; comparing the instructed pilot signal window size to the pilot signal window size lower limit; responsive to determining the instructed pilot signal window size to be below the pilot signal window size lower limit, configuring a pilot signal search with a window size equal to the pilot signal window size lower limit, searching for the pilot signal with the window size equal to the pilot signal window size lower limit, including generating result data, and analyzing only a middle portion of the result data corresponding to the instructed pilot signal window size.
