Abstract
Techniques to efficiently process paging channels in an asynchronous wireless communication system. In one aspect, if the base stations are not synchronized with each other and a remote terminal's designated page time is different from base station to base station, the remote terminal can wake up based on the earliest base station in a reacquisition search list that includes candidate base stations to which the remote terminal may be handed off. In another aspect, the criteria to select base stations for evaluation as reacquisition targets may be based on the received power of the base stations as well as their timing, both of which may be made relative to that of a preferred base station. In yet another aspect, the remote terminal may wake up multiple times in a particular paging cycle (i.e., a frame cycle or a DRX cycle) if there are one or more candidates base station to which the remote terminal may be handed off.
