Abstract
In order to efficiently schedule data transmission of a plurality of terminals, the wireless communication terminal receives a trigger frame indicating uplink multi-user transmission, and transmits an uplink multi-user PPDU (PLCP Protocol Data Unit) in response to the received trigger frame. In this case, the trigger frame and the non-legacy preamble of the uplink multi-user PPDU include remaining TXOP (Transmission Opportunity) time information of the uplink multi-user transmission process.
