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 an SIG-A field and an 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,
wherein the transmitting of the frame transmits the SIG-B field using a frequency bandwidth indicated in the SIG-A field, and
wherein the bit information indicates a partial allocation identifier (AID) used by each channel in the OFDMA mode, and a modulation and coding mode used by each channel in the OFDMA mode.
