Apparatuses, methods, and systems are disclosed for adjusting a contention window size. One apparatus includes a processor and a transceiver comprising a plurality of transmit panels. The transceiver initiates a first channel occupancy ('CO') using at least one transmit panel in response to a successful Listen-Before-Talk procedure and transmits a directional transmission using a first transmit panel, the first transmit panel selected from the plurality of transmit panels. The processor determines whether the directional transmission was successfully received by a recipient and updates a first contention window size specific to the first transmit panel. The processor performs a subsequent Listen-Before-Talk procedure using the updated first contention window size prior to a subsequent directional transmission using the first transmit panel.
