Abstract
Disclosed are systems and methods which provide communication links optimized with respect to particular subscriber units. Preferred embodiments utilize multiple information components with respect to the arrival of signals associated with target subscriber units in providing optimized communication links. Most preferably, direction information and information with respect to the signal spread experienced in the communication channel is used. Moreover, preferred embodiments utilize subscriber unit speed information in providing optimized communication link determinations.

A system for selecting a beam configuration for use in a communication link, said system comprising:
- a speed estimator providing speed information with respect to a subscriber unit using corresponding array response vector information determined from a reverse link;
- and
- a beam selector providing selection of a beam configuration for use in a communication link with respect to said subscriber unit from a plurality of beam configurations using said speed information, and
- a beam configuration analyzer providing beam merit information for a plurality of beam configurations with respect to said subscriber unit, wherein said beam configuration analyzer uses said array response vector information in providing said beam merit information, wherein said beam merit information is weighted by said beam selector using said speed information for selection of said beam configuration.
A system for selecting an optimum wireless link beam configuration, said system comprising:
- speed estimation circuitry providing speed information with respect to a subscriber unit, wherein said speed information is determined by said speed estimation circuitry using array response vector information of a signal from said subscriber unit as received by an antenna array;
- beam analyzer circuitry providing beam merit information with respect to said subscriber unit for a plurality of beam configurations, wherein said beam merit information is determined by said beam analyzer circuitry using said array response vector information;
