1. A wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to,
perform a first backoff procedure for a transmission of a wireless frame,
wherein the first backoff procedure is performed within a contention window for the transmission of the wireless frame, and
transmit the wireless frame to one or more terminals based on the first backoff procedure,
wherein the transmission of the wireless frame is determined to be successful when at least one response frame is received in response to the wireless frame from at least one among the one or more terminals,
wherein the transmission of the wireless frame is determined to fail when all of response frames are not received in response to the wireless frame from all of the one or more terminals, and
wherein a size of the contention window is increased based on a minimum contention window size and a maximum contention window size according to an access category when the transmission of the wireless frame is determined to fail.
