Multiple network allocation vector operation
A wireless device determines a Basic Service Set (BSS) associated with a wireless transmitter by receiving a first frame, determining an address of the first frame, receiving a second frame, and determining, using the address of the first frame, a property of the second frame. Determining the property of the second frame may include determining whether the second frame is intra-BSS frame or an inter-BSS frame. Determining the property of the second frame may be performed by comparing an address of the second frame with the address of the first frame, and the second frame determined to be an intra-BSS frame when the address of the first frame matches the address of the second frame, and determined to be an inter-BSS frame otherwise. The address of the first frame may be a transmitter address (TA).
1. A method performed by a wireless device, the method comprising:
receiving, by the wireless device, a first frame;
determining, by the wireless device, a Transmission Opportunity (TXOP) holder address using the first frame and saving the TXOP holder address;
receiving, by the wireless device, a second frame;
determining, using the saved TXOP holder address and an address of the second frame, whether the second frame is an intra-Basic Service Set (intra-BSS) frame; and
in response to determining, using the saved TXOP holder address and the address of the second frame, that the second frame is the intra-BSS frame, updating, by the wireless device, an intra-BSS Network Allocation Vector (NAV).
2. The method of claim 1 , wherein determining whether the second frame is the intra-BSS frame comprises:
comparing the address of the second frame with the saved TXOP holder address; and
determining that the second frame is the intra-BSS frame in response to the saved TXOP holder address matching the address of the second frame.
3. The method of claim 1 , wherein the address of the second frame is a receiver address (RA).
4. The method of claim 1 , wherein the TXOP holder address is a Transmitter Address (TA) of the first frame.
5. The method of claim 1 , wherein the first frame is not targeted to the wireless device.
6. The method of claim 1 , wherein the second frame is not targeted to the wireless device.
7. The method of claim 1 , wherein determining the TXOP holder address includes determining that the first frame is in an intra-BSS transmission of a BSS the wireless device is associated with.
8. The method of claim 1 , wherein the TXOP holder address is an address of a holder of a TXOP in which the first frame is transmitted.
9. The method of claim 8 , wherein receiving the second frame comprises receiving the second frame within a duration of the TXOP.
10. The method of claim 1 , wherein receiving the second frame comprises receiving the second frame within a Short Intra-Frame Space (SIFS) of an end of receiving the first frame.
11. The method of claim 1 , wherein the second frame is a control frame that does not have a transmitter address (TA) field.
12. The method of claim 1 , wherein the first frame is a request-to-send (RTS) frame or a data frame.
13. A wireless device, comprising:
a receiver circuit,
wherein the wireless device is to:
receive, using the receiver circuit, a first frame;
determine a Transmission Opportunity (TXOP) holder address using the first frame and save the TXOP holder address;
receive, using the receiver circuit, a second frame; and
determine, using the saved TXOP holder address and an address of the second frame, whether the second frame is an intra-Basic Service Set (intra-BSS) frame; and
in response to determining, using the saved TXOP holder address and the address of the second frame, that the second frame is the intra-BSS frame, update an intra-BSS Network Allocation Vector (NAV).
14. The wireless device of claim 13 , wherein determining whether the second frame is an intra-BSS frame comprises:
comparing the address of the second frame with the saved TXOP holder address; and
determining that the second frame is the intra-BSS frame in response to the saved TXOP holder address matching the address of the second frame.
15. The wireless device of claim 13 , wherein the address of the second frame is a receiver address (RA) and the TXOP holder address is a transmitter address (TA).
16. The wireless device of claim 13 , wherein the first frame is not targeted to the wireless device, the second frame is not targeted to the wireless device, or both the first frame and the second frame are not targeted to the wireless device.
17. The wireless device of claim 13 , wherein the second frame is a control frame without a transmitter address (TA) field.
18. The wireless device of claim 13 , wherein determining the TXOP holder address includes determining that the first frame is in an intra-BSS transmission of a BSS the wireless device is associated with.
19. The wireless device of claim 13 ,
wherein the first frame is received within a TXOP, and
wherein the second frame is received within the TXOP.
