Abstract
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.
Claims50
A method of selectively directing base station RF communication signals in a wireless telecommunication system wherein a base station conducts wireless RF communications with a plurality of user equipments (UEs), the method comprising:
- determining an estimated location of a UE;
- determining relative location data using the estimated UE location and a known location of a base station antenna system;
- calculating beam forming criteria based in part on the relative location data;
- and
- forming a directed beam for RF communication signals between said UE and said base station antenna system based on said calculated beam forming criteria such that said directed beam encompasses the estimated location of said UE.
A base station for conducting wireless RF communications with a plurality of user equipments (UEs) in a wireless telecommunication system comprising:
- an RF module and an associated antenna array system;
- a beam former operatively associated with the RF module to form a desired beam within a range of beams of which the antenna array system is capable;
- and
- a geolocation processor coupled to said beam former that is configured to process UE geolocation data relative to data of a location of said antenna array system and output selected parameters to the beam former such that the beam former controls the RF module to transmit or receive communication data for a selected UE in a shaped beam that encompasses an estimated location of the selected UE where geolocation data which corresponds to the estimated location of the selected UE is processed by said geolocation processor.
A user equipment (UE) for conducting wireless RF communications with base stations having known locations in a wireless telecommunication system comprising:
- an RF module and an associated antenna array system;
- a beam former operatively associated with the RF module to form a desired beam within a range of beams which the antenna array system is capable of producing;
- and
- a geolocation processor coupled to said beam former that is configured to process UE geolocation data of an estimated UE location relative to data of the known location of a selected base station and output selected parameters to the beam former such that the beam former controls the RF module to transmit or receive communication data for the selected base station in a shaped beam that encompasses the known location of the selected base station where UE geolocation data relative to the known location of the selected base station is processed by said geolocation processor.
