Abstract
A method for receiving a data frame by a receive station in a wireless local area network (WLAN) system is provided. The method includes: receiving a signal A field including a multiple input multiple output (MIMO) indicator and including a first signal A sub-field and a second signal A sub-field each transmitted as different orthogonal frequency division multiplexing (OFDM) symbols; determining a processing type of a subsequently transmitted signal based on the signal A field; receiving a data field; and obtaining data by interpreting the data field based on the processing type of the signal. Different modulation schemes are applied to a higher frequency region and a lower frequency region on a subcarrier of the first signal A sub-field.
