Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A transceiver, comprising:
multiple transmission and reception points configured to transmit and receive multiple beams in a wireless communication medium, each beam of the multiple beams being oriented in a direction that is different from a direction of each other beam of the multiple beams;
a receiver coupled to the multiple transmission and reception points; and
a transmitter coupled to the multiple transmission and reception points,
the transceiver configured to:
perform a first directional clear channel assessment (CCA) sensing on at least one first beam of the multiple beams in the wireless communication medium,
determine whether the at least one first beam of the multiple beams is busy;
initialize a back-off timer based on a determination that the at least one first beam is busy;
decrease the back-off timer a first predetermined amount based on a determination that at least one second beam of the multiple beams is idle;
transmit data over the at least one second beam of the multiple beams based on the back-off timer equaling a second predetermined amount;
determine 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, perform a second directional CCA sensing on at least one third beam of the multiple beams in the wireless communication medium during the transmission gap; and
determine that the at least one third beam is busy and, in response, postpone the second upcoming transmission and perform a third directional CCA sensing on at least one fourth beam of the multiple beams in the wireless communication medium during a future channel occupancy time.
