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.

Abstract:
A method for assigning tracking elements includes sorting a list of potential assignments according to a diversity criterion. In one example, a list of received signal instances is sorted first according to a measure of energy and then sorted again according to the diversity criterion. In a further embodiment, a demodulation element may be labeled available for assignment yet continue to output demodulated symbols in a locked state. Applications to a mobile station of a CDMA system for cellular telephony are discussed.
Abstract:
Captured data is stored in a storage element. The captured data represents a record of at least one observed phenomenon. For example, the captured data may represent a still image or a video sequence. In response to a determination that a predetermined condition exists, the captured data is retrieved from the storage element and transmitted over a wireless datalink.

Abstract:
Techniques to efficiently process paging channels in an asynchronous wireless communication system (100). In one aspect, if the base stations (104a, b, c) are not synchronized with each other and a remote terminal's (106) designated page time is different from base station to base station, the remote terminal (106) can wake up based on the earliest base station in a reacquisition search list (712) 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 (512) of the base stations as well as their timing (514), 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.
