Title: METHODS AND SYSTEM FOR LBT THRESHOLD SETTING FOR DIRECTIONAL RECEPTION AND TRANSMISSION
Abstract:
A method and system for LBT or CCA threshold setting for directional reception and transmission are provided. In an embodiment, a method in a wireless device for determining if a channel is clear in an unlicensed band channel in a wireless network includes detecting, with the wireless device, an energy along a first beamforming direction. The method also includes determining, with the wireless device, an energy detection threshold. The method also includes determining, with the wireless device, whether the unlicensed band channel is clear in at least the first receiving direction according to the energy and the energy detection threshold.
