1. Wireless communication method performed by a wireless communication apparatus in a wireless local area network (WLAN) system, the wireless communication method comprising:
generating a frame comprising a SIG-A field and a SIG-B field, wherein the SIG-B field comprises bit information that comprises subchannel allocation information in an Orthogonal Frequency-Division Multiple Access (OFDMA) mode where different subchannels are allocated to different users and simultaneous data transmission to multiple users is allowed; and
transmitting the generated frame to the multiple users, and
wherein the SIG-B field further comprises bit information indicating a number of space-time streams (NSTS) of channels transmitted in the OFDMA mode, and bit information indicating a modulation and coding mode used by each channel in the OFDMA mode.
