4. A method of operating a wireless communication terminal included in a plurality of wireless communication terminals, the method comprising:
receiving a first trigger frame for triggering multiple access to a base wireless communication terminal,
transmitting, at a designated time, information on whether each of channels is idle at the designated time to the base wireless communication terminal simultaneously with a transmission of information on whether each of the channels is sensed to be idle by one or more other wireless communication terminals from the one or more other wireless communication terminals, wherein the designated time is determined based on a short inter-frame space (SIFS) and a time when the first trigger frame has been received,
receiving a second trigger frame including information on a channel allocated to the wireless communication terminal;
obtaining the information on the channel allocated to the wireless communication terminal from the second trigger frame; and
accessing the base wireless communication terminal through the channel allocated to the wireless communication terminal,
wherein each of the channels corresponds to each 20 MHz channel of a 160 MHz channel.
