摘要
The present invention discloses methods and devices for communicating data in a Wireless Local Area Network (WLAN). An orthogonal frequency division multiplexing (OFDM) frame is communicated between an access point (AP) and a station (STA). The OFDM frame comprises a preamble section and a data payload section. The data payload section includes communication payload data and reference signal (RS) data pertaining to a wireless channel. The RS data comprises one of an orthogonal sequence-based reference signal (OSRS), a quasi-orthogonal sequence-based reference signal (QOSRS), and a tone interleaved long training field (TIL) -based RS.
