1. A wireless communication terminal that wirelessly communicates with a base wireless communication terminal, the wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to: receive a trigger frame from the base wireless communication terminal,
transmit, to the base wireless communication terminal, a physical layer protocol data unit (PPDU) based on the trigger frame using the transceiver,
switch a parameter set, which is a set of parameters used for a channel access, from a first parameter set to a second parameter set based on whether the base wireless communication terminal triggers a multi-user uplink transmission participation of the wireless communication terminal,
when a medium access control (MAC) protocol data unit (MPDU) included in the PPDU does not request an immediate response, set a second parameter set timer for an access category of the MPDU when the transmission of the PPDU ends,
when the MPDU included in the PPDU requests an immediate response, set the second parameter set timer for the access category of the MPDU for which an ACK is received when the immediate response is received,
when the second parameter set timer expires, terminate an application of the second parameter set, and
access a channel according to an access category priority of data to be transmitted to the base wireless communication terminal by the wireless communication terminal and the parameter set.
