Abstract

Various embodiments disclosed herein provide for a multi-beam Listen Before Talk which is a coexistence mechanism used by wireless technologies such as Wi-Fi, to access unlicensed shared spectrum, such as the ISM UNII bands (5 GHz). The embodiments disclosed herein enable a transceiver to determine whether or not there is activity on a beam to avoid causing interference. The transceiver can determine that there is activity in a certain direction, and then avoid transmitting on a beam in that direction until the activity ceases. While there is activity in a first beam, the transceiver can continue to transmit on other beams that will not cause interference with a transmission associated with the first beam.
