1. A wireless communication terminal, comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive, through the transceiver, a trigger frame including a specific field,
wherein the specific field indicates whether transmission of a next trigger frame soliciting uplink transmission to one or more terminals is scheduled after transmission of the trigger frame and is used to determine a state of the wireless communication terminal,
wherein the next trigger frame is transmitted within a same service period (SP) as a service period in which the trigger frame is transmitted when the specific field is set to a value indicating transmission of the next trigger frame, and
perform a multi-user uplink transmission in response to the trigger frame.
