Wireless coexistence based on network allocation vector usage

A wireless apparatus, comprising:

• a wireless transceiver;
• a wireless local area network (WLAN) controller coupled to the wireless transceiver, said WLAN controller configured to send and receive packets in accordance with a WLAN protocol;
• a second controller coupled to the wireless transceiver, the second controller configured to send and receive packets in accordance with a second wireless protocol;
• and
• scheduling logic coupled to the WLAN and second controllers, the scheduling logic determines whether a WLAN communication will complete before an end of a WLAN active time period in which the WLAN controller has control over a wireless medium, and if the scheduling logic determines that the WLAN communication will not complete before the end of the WLAN active time period, the scheduling logic causes the WLAN controller to transmit a WLAN packet that encodes a network allocation vector (NAV) value that prevents an access point from using the wireless medium until an end of second time period, the second controller configured to use the wireless medium during the second time period.
