Abstract
A system and method of performing a beam discovery between a device and a plurality of other devices in a wireless network is disclosed. Sector training sequences to a plurality of other devices are transmitted via a transmit directional antenna having a set of transmit sectors. A plurality of feedback messages are received from the plurality of other devices, where the plurality of feedback messages are indicative of optimum transmit sectors that have been determined at the other devices based at least in part on the sector training sequences. Beam training sequences are transmitted to the plurality of other devices via the transmit directional antenna. A plurality of feedback message indicative of optimum transmit beam directions within the optimum transmit sectors are received from the plurality of other devices.
