Classification: CPC H | IPC H

Claim 8:
9. A wireless communication method performed by a wireless communication apparatus in a wireless local area network (WLAN) system, the wireless communication method comprising:
receiving, by the wireless communication apparatus corresponding to one of multiple users from a transmission apparatus, 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 the multiple users is allowed; and
determining each of subchannels to be used for communications based on at least the subchannel allocation information,
wherein the receiving of the frame includes receiving 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.
