Managing searcher and tracker resources in a wireless communication device
First Claim
1. A method of managing beam tracker resources in a Wireless Communication Device (WCD) that tracks one or more tracked beams using the beam tracker resources, each of the one or more tracked beams originating from a respective one of one or more tracked transponders, comprising:
- (a) determining a tracked-beam (TB) searcher energy for each of the tracked beams;
(b) determining an untracked-beam (UB) searcher energy for each of one or more untracked beams from each of the tracked transponders;
(c) attempting to determine, based on the TB and UB searcher energies from steps (a) and (b), a preferred untracked beam among the one or more untracked beams that should become a tracked beam; and
(d) assigning a tracking resource to track the preferred untracked beam when the attempt to determine the preferred untracked beam is successful.

Abstract
A Wireless Communication Device (WCD) includes multiple fingers that track one or more tracked transponder beams. Each tracked beam is from a respective tracked transponder. The WCD determines a tracked-beam searcher energy for each of the tracked beams, and an untracked-beam searcher energy for each of one or more untracked beams from each of the tracked transponders. The WCD attempts to determine a preferred one of the untracked beams that should become a tracked beam. This determination is made based on the tracked-beam and the untracked-beam searcher energies. The WCD assigns, or alternatively, reassigns, a finger to the preferred untracked beam when the attempt to determine a preferred untracked beam is successful. The transponders may be satellites or base stations.

21. An apparatus for managing finger resources in a Wireless Communication Device (WCD), the WCD including multiple fingers that track one or more beams originating from respective ones of one or more tracked transponders, comprising:
-
an energy estimator adapted to determine a tracked-beam (TB) searcher energy for each of the tracked beams, and determine an untracked-beam (UB) searcher energy for each of one or more untracked beams from each of the tracked transponders;
means for attempting to determine, based on the TB and UB searcher energies from the energy estimator, a preferred untracked beam among the one or more untracked beams that should become a tracked beam; and
means for assigning one of the multiple fingers to track the preferred untracked beam when the attempt to determine the preferred untracked beam is successful. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
