1. A wireless communication device, comprising:
a receiver configured to receive a first frame specifying the wireless communication device to perform an uplink multi-user transmission;
a transmitter is configured to transmit a second frame in the uplink multi-user transmission in response to the first frame specifying the wireless communication device being received; and
controlling circuitry configured to activate the timer after the transmitter transmits the second frame, wherein
the controlling circuitry changes, after the timer times out, a value of a first parameter, wherein the first parameter includes at least one of:
a value of a transmission opportunity (TXOP) limit,
a minimum value and maximum value of a contention window, or
a value of AIFSN (Arbitration Interframe Space Number), and
the transmitter is configured to transmit a third frame based on the changed first parameter.
