1. A wireless communication terminal comprising:a transceiver; and
a processor,
wherein the processor is configured to:
receive, by using the transceiver, a Medium Access Control (MAC) frame which triggers a simultaneous uplink transmission of a plurality of wireless communication terminals including the wireless communication terminal, from a base wireless communication terminal,
perform a clear channel assessment (CCA) in at least one of channels in response to receiving the MAC frame, and
transmit, to the base wireless communication terminal, a response MAC frame for the MAC frame based on the CCA, when a predetermined time elapses after receiving operation of the MAC frame,
wherein the predetermined time has a value which is applied in the simultaneous uplink transmission of the plurality of wireless communication terminals.
