Abstract
In an example of wireless multi-user communication, a station may generate a frame and provide the frame for transmission to multiple stations. The frame may include a long training field (LTF) portion and a data portion. The LTF portion and the data portion may be associated with a plurality of tones. Each group of the plurality of tones in the data portion may be associated with a respective steering matrix. Each group of the plurality of tones in the data portion may include two or more tones of the plurality of tones. One or more of the multiple stations may receive the frame and process the frame. Other methods, apparatus, and computer-readable media are also disclosed.
