Abstract
A method for beamforming training is disclosed including SNR values with each of the SNR values associated with one of the antenna identifiers (IDs) in a first frame identifying different radio frequency (RF) chains for a process of beamforming training; receiving and transmitting the first frame bi-directionally between multiple pairs of communicating nodes, wherein each pair of the communicating nodes has at least one initiator node and one responder node; receiving feedback of the SNRs associated with the antenna IDs from two or more responder nodes of the multiple pairs of the communicating nodes to choose an RF chain as favorable transmit antenna for transmission; and determining respective one from the multiple antenna sectors of the multiple antennas for transmission for the responder nodes according to the feedback. A central network controller and a system are also disclosed herein.
