  • Publication number: 20210288774
    Abstract: A wireless device transmits a frame by determining a plurality of Resource Units (RUs) of the frame, providing pilots in a first RU of the frame at a first set of positions, providing pilots in a second RU of the frame at a second set of positions, and transmitting the frame. The first set of positions is different from the second set of positions. A wireless device receives a frame including an RU including pilots and processes the pilots. When an RU for the data symbol includes an odd-numbered lowest subcarrier, the pilots are included at a first set of positions in the resource unit. When the RU includes an even-numbered lowest subcarrier, the pilots are included at a second set of positions in the resource unit. The second set of positions is different from the first set of positions.

  • Publication number: 20210266967
    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 transmitter address (TA).
