Beamforming methods and methods for using beams

Abstract

A method, apparatus, system, and computer readable medium may be used to perform beamforming. The method may include a first communication device sending a first plurality of beamforming training frames to a second communication device using a first beamforming weight vector; the first communication device receiving from the second communication device a second beamforming weight vector; and the first communication device sending a second plurality of beamforming training frames to the second communication device using the second beamforming weight vector. The apparatus, method, system, and computer readable media may use spatial diversity with beam switching, spatial diversity with a single beam, weighted multipath beamforming training, single user spatial multiplexing, and beamforming training for beam division multiple access (BDMA).

What is claimed is: 
     
         1 . A method performed by a first station (STA) comprising a plurality of antennas, the method comprising:
 partitioning the plurality of antennas into at least a first group of antennas and a second group of antennas, wherein the first group of antennas is associated with a first sector to a second STA, and the second group of antennas is associated with a second sector to the second STA;   transmitting, to the second STA, a plurality of beamforming training frames using the first group of antennas and the second group of antennas;   receiving, from the second STA, a first beamforming weight vector for sending signals on the first group of antennas; and   receiving, from the second STA, a second beamforming weight vector for sending signals on the second group of antennas.
