Network allocation vector operations to reduce channel access delay

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors, the instructions to configure the one or more processors to cause an apparatus of a wireless device to:

• select a first one or more directional multi-gigabit (DMG) antennas from DMG antennas of the wireless device;
• configure the wireless device to perform a clear channel assessment (CCA) for each of a plurality of CCA configurations applicable to the first one or more DMG antennas, wherein each CCA configuration comprises a second one or more of the DMG antennas;
• and
• if each CCA configuration applicable to the first one or more DMG antennas indicate the channel is idle, decrease a backoff time, and, if the backoff time is zero, configure the wireless device to transmit a packet on the channel using the first one or more DMG antennas.

A method performed by an apparatus of a wireless device, the method comprising:

• selecting a first one or more directional multi-gigabit (DMG) antennas from DMG antennas of the wireless device;
• configuring the wireless device to perform a clear channel assessment (CCA) for each of a plurality of CCA configurations applicable to the first one or more DMG antennas, wherein each CCA configuration comprises a second one or more of the DMG antennas;
• and
• if each CCA configuration applicable to the first one or more DMG antennas indicate the channel is idle, decreasing a backoff time, and, if the backoff time is zero, configuring the wireless device to transmit a packet on the channel using the first one or more DMG antennas.
