1. A base wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to transmit, by using the transceiver, a Multiple-Request to Send (M-RTS) frame to a plurality of wireless communication terminals, 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 the plurality of wireless communication terminals, and
receive a Clear to Send (CTS) frame which is a response to the M-RTS frame from the at least one of the plurality of wireless communication terminals and transmitted through a sub-frequency band allocated to the at least one of the plurality of 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.
