Abstract
The present disclosure discloses a communication method in a wireless local area network and a communication device. The method includes: generating a message frame, where the message frame includes an antenna information field of each of a plurality of antennas and a plurality of Modulation and Coding Schema MCS fields corresponding to each antenna, where each of the plurality of MCS fields is used to indicate an MCS, and an antenna information field of each antenna is used to indicate identification information of the antenna; and transmitting the message frame to a station. The embodiments of the present disclosure provide feasible implementation manners for a combination of the multiple-input multiple-output technology (English: Multiple-Input Multiple-Output, MIMO for short) and the orthogonal frequency division multiple access technology (English: Orthogonal Frequency Division Multiple Access, OFDMA for short), which can improve spectrum utilization and improve regional throughput.
