A wireless communication device, system and method. The device includes a memory, and processing circuitry coupled to the memory. The processing circuitry includes logic to: determine a training field length associated with a directional multigigabit (DMG) CTS frame of another wireless communication device; determine a Clear-To-Send time (CTS_Time) parameter based at least in part on the training field length; determine a transmit opportunity (TXOP) continuation timeout for the device based on the CTS_Time parameter; and set a network allocation vector (NAV) for the device based on the TXOP continuation timeout.
