초록

The present invention relates to a method and system using dynamic beam forming for wireless communication signals in a wireless network. Base stations and/or UEs are provided with antenna systems having a range of beam forming selections. Relative base station and UE locations are one type of criteria used to make beam forming decisions.

청구항

What is claimed is: 1. A wireless telecommunication system comprising: a plurality of base stations for conducting wireless RF communications with a mobile user equipment (UE); each based station having: an RF module and an associated antenna system that is located at a predetermined position and a geographic transmission range which overlaps with the transmission range of at least one other of said base stations; and a beam former operatively associated with the RF module to form a set of desired beams within a range of beams which the base station's ...
