Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. A wireless communication apparatus comprising:
a processor to generate a frame comprising an SIG-A field and an SIG-B field, wherein the SIG-B field comprises bit information comprising 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
a transmitter to transmit the generated frame to the multiple users,
wherein the transmitter, in order to transmit the generated 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.
