Abstract
Systems, apparatuses, and methods for implementing enhanced beamforming training procedures are disclosed. A system includes a transmitter communicating over a wireless link with a receiver. To maintain a high quality of transmission over the wireless link, the transmitter and receiver perform periodic beamforming training procedures to test the various sectors of the transmit and receive antennas. In a wide sector sweep procedure, the transmitter and receiver test wide sectors to find the best wide transmit and receive sectors for transferring data. Then in a narrow sector sweep procedure, narrow sectors within and/or adjacent to the best wide sectors are tested, to find the best narrow sectors. This reduces the amount of sectors that are tested during the enhanced beamforming training procedure by skipping those narrow sectors that are far away from the best wide sectors.
