Claim 14:
15. A method for accessing a wireless medium, the method comprising:
performing, at a transmitter, a first directional clear channel assessment (CCA) sensing on a set of multiple beams in the wireless medium, each beam of the set of multiple beams being oriented in a direction that is different from a direction of each other beam of the set of multiple beams;
determining, at the transmitter, whether at least one first beam of the set of multiple beams is busy;
initializing, at the transmitter, a back-off timer based on a determination that at least one first beam is busy;
decreasing, at the transmitter, the back-off timer a first predetermined amount based on a determination that all beams of the set of multiple beams are idle;
transmitting, by the transmitter, data over at least one idle beam of the set of multiple beams based on the back-off timer equaling a second predetermined amount;
determining, at the transmitter, that a transmission gap between two successive transmissions comprising a first transmission and a second upcoming transmission is greater than a threshold value and, in response, performing, at the transmitter, a second directional CCA sensing on at least one second beam of the set of multiple beams in the wireless medium during the transmission gap; and
further determining, at the transmitter, that the at least one second beam is busy and, in response, postponing, by the transmitter, the second upcoming transmission and performing a third directional CCA sensing on at least one third beam of the set of multiple beams in the wireless medium during a future channel occupancy time.
