Abstract

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 transmit address (TA).

Dependent claims

A method performed by a first wireless device for determining a Basic Service Set (BSS) associated with a wireless transmitter, the method comprising:

receiving, by the first wireless device, a first frame;
determining an address of the first frame;
receiving, by the first wireless device, a second frame;
determining, by the first wireless device, an address of the second frame;
determining, using the address of the first frame and the address of the second frame, whether the second frame is an inter-BSS frame;
and
setting an inter-BSS Network Allocation Vector (NAV) in response to determining that the second frame is an inter-BSS frame,
wherein the first wireless device comprises the inter-BSS NAV and an intra-BSS NAV different from the inter-BSS NAV.
