Wireless communication method and wireless communication terminal

A wireless communication terminal comprising:

• a transceiver;
• and
• a processor,
• wherein the processor is configured to receive, by using the transceiver, a M-RTS (Multiple-Request to Send) frame from a base wireless communication terminal, wherein the M-RTS frame is a medium access control (MAC) frame and includes a plurality of channel vector fields, wherein each of the plurality of channel vector fields indicates information on an allocated sub-frequency band which is allocated to a wireless communication terminal corresponding to each of the plurality of channel vector fields among a plurality of wireless communication terminals, and
• transmit a Clear to Send (CTS) frame which is a response to the M-RTS frame to the base wireless communication terminal through a sub-frequency band allocated to the wireless communication terminals,
• wherein bits of each of the plurality of channel vector fields are divided into a first one or more bits indicating a location of a channel, among a plurality of channels, which includes the allocated sub-frequency band, and a second one or more bits indicating a location and a size of a sub-channel corresponding to the allocated sub-frequency band within the channel,
• wherein the sub-channel is included in the channel.
