1. A wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive, through the transceiver, a first control frame which reserves a channel for a transmission between an access point and a first plurality of wireless communication terminals, includes terminal identifier fields, and includes information on each of channels respectively allocated to each of the first plurality of wireless communication terminals, from the access point, wherein a receiver address of the first control frame is a group address which indicates a second plurality of wireless communication terminals including the first plurality of wireless communication terminals, wherein the terminal identifier fields include a plurality of association identifiers, wherein each of the plurality of association identifiers respectively identifies the each of the first plurality of wireless communication terminals, and
transmit, by using the transceiver, a second control frame in response to the first control frame to the access point through a channel allocated to the wireless communication terminal which is indicated by the information when the wireless communication terminal determines that the channel allocated to the wireless communication terminal is idle for a predetermined time and at least one of the terminal identifier fields indicates the wireless communication terminal,
wherein an inter-frame space between the first control frame and the second control frame is the predetermined time.
