Abstract

Apparatuses and methodologies are described that enhance performance in a wireless communication system using beamforming transmissions. According to one aspect, the channel quality is monitored. Channel quality indicators can be used to select a scheduling technique, such as space division multiplexing (SDM), multiple-input multiple output (MIMO) transmission and opportunistic beamforming for one or more user devices. In addition, the CQI can be used to determine the appropriate beam assignment or to update the beam pattern.

Description

[0001] Claim of priority under 35 U.S.C § 119 [0002] This patent application claims priority over Provisional Application No. 60 / 672,575, filed April 19, 2005, entitled "CHANNEL QUALITY REPORTING FOR ADAPTIVE SECTORIZATION IN WIRELESS COMMUNICATION SYSTEMS," and 60 / 710,419, filed August 22, 2005 , which is assigned to the assignee herein, and is hereby expressly incorporated herein by reference. technical field [0003] The following description relates generally to wireless communications, and more particularly to communication schemes for wireless communications systems. Background technique [0004] Wireless networking systems have become a popular means by which most people communicate throughout the world. To meet consumer demands and to increase portability and convenience, wireless communication devices have become smaller and more powerful. Consumers have found many uses for wireless communication devices such as mobile phones, personal digital assistants (PDAs)...
