Abstract: A method for transmitting a frame includes generating an omni portion of the frame, the omni portion including a non-beamformed long training field and a signal field, the non-beamformed long training field including channel estimation information used to decode the signal field, the non-beamformed long training field configured to be transmitted through one of multiple antennas and multiple streams. The method also includes generating a multi-stream portion of the frame, the multi-stream portion including a data field and a multi-stream long training field, the multi-stream long training field including station-specific decoding information for station-specific data in the data field. The method further includes applying a beamforming indicator to the signal field of the omni portion, and transmitting the frame.
