Abstract: A method includes determining, by an access point device, whether a channel is clear. The channel includes an unlicensed carrier. The method also includes sending an omnidirectional request-to-send transmission containing a beam identifier that the access point device will use for transmitting data; and receiving a clear-to-send message in response to the request-to-send message. In response to receiving the clear-to-send message, the method includes performing directional transmission of data using the beam identified in the request-to-send transmission.
