Title:
METHOD AND APPARATUS FOR USING SWITCHED MULTIBEAM ANTENNAS IN A MULTIPLE ACCESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO2004032393
Kind Code:
A3
Abstract:
In order to increase a capacity, or a number of mobile stations (MSs), or users, that may engage in concurrent communication sessions, a communication system (100) is provided that schedules a different MS, or user, (110-112) in each beam of multiple predetermined, fixed beams (160-165) associated with a coverage area, for example, a sector. By simultaneously scheduling a user in each beam of the multiple beams, a performance and throughput of communication system is significantly increased over the prior art. In one embodiment of the present invention, a portion of a shared communication channel that is allocated to each MS is concurrently transmitted to each MS via a beam associated with the MS. In other embodiments of the present invention, voice channels, data channels, and control channels associated with each MS scheduled in a beam may be concurrently transmitted to each MS via the beam associated with the MS.
