NETWORK ALLOCATION VECTOR TYPES AND TRANSMISSION OPPORTUNITY TYPES FOR SPATIAL REUSE

摘要

In an example of wireless communications, a transmitting station may set multiple network allocation vectors (NAVs) to reserve a communication medium for transmitting a frame in the amount of time indicated by the NAVs. A receiving station that receives a frame may identify which NAV is intended to be set by the receiving station. The receiving station may update a first type of NAV with duration information from the frame when the frame is received from a same wireless network, and update a second type of NAV with duration information from the frame when the frame is received from a different wireless network. The receiving station may ignore setting the NAV when the frame is received from the different wireless network. Alternatively, the receiving station may not ignore setting the NAV when the frame is received from the same wireless network. Other methods, apparatus, and computer-readable media are also disclosed.

主权项

1. A wireless device for facilitating spatial reuse, the wireless device comprising:
one or more memories; and one or more processors coupled to the one or more memories, the one or more processors configured to: receive a frame from a first station, the received frame having duration information;
identify whether the received frame is associated with a first wireless network or a second wireless network;update a first network allocation vector (NAV) with the duration information from the received frame when the received frame is associated with the first wireless network; andupdate a second NAV with the duration information from the received frame when the received frame is associated with the second wireless network, wherein the wireless device is permitted to ignore the second NAV.
