SYSTEM AND METHOD FOR ANTENNA TRAINING OF BEAMFORMING VECTORS HAVING REUSE OF DIRECTIONAL INFORMATION
First Claim
1. A method of reusing existing directional information to configure antennas in a wireless network, the method comprising:
- retrieving existing directional information, the existing directional information having been established in a previous antenna training session with a receiver;
performing a signal-to-noise ratio (SNR) estimation procedure comprising;
transmitting an SNR estimation probe message to the receiver via a directional antenna tuned with the existing directional information, anddetermining whether an estimated SNR value associated with the SNR estimation probe message is equal to or greater than a threshold SNR value; and
transmitting a data message to the receiver via the directional antenna tuned with the existing directional information if it is determined that the estimated SNR value is equal to or greater than the threshold SNR value.

Abstract
A system and method for reusing existing directional information to configure antennas in a wireless network is disclosed. The method includes retrieving existing directional information, the existing directional information having been established in a previous antenna training session with a receiver. The method further includes performing a signal-to-noise ratio (SNR) estimation procedure comprising: transmitting an SNR estimation probe message to the receiver via a directional antenna tuned with the existing directional information, and determining whether an estimated SNR value associated with the SNR estimation probe message is equal to or greater than a threshold SNR value. The method further includes transmitting a data message to the receiver via the directional antenna tuned with the existing directional information if it is determined that the estimated SNR value is equal to or greater than the threshold SNR value.
