1. A wireless communication terminal wirelessly communicating 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 which triggers uplink transmission, wherein the trigger frame indicates a physical layer protocol data unit (PPDU) format of the uplink transmission among a plurality of PPDU formats of the uplink transmission, and
perform the uplink transmission according to the PPDU format of the uplink transmission indicated by the trigger frame,
wherein the uplink transmission is included in a mixed uplink transmission,
the mixed uplink transmission is performed through a mixed PPDU which is for a simultaneous transmission of first format PPDU from the wireless communication terminal and second format PPDU from a wireless communication terminal which is different from the wireless communication terminal using orthogonal frequency-division multiple access (OFDMA),
wherein the first format PPDU is for non-legacy wireless communication terminal and the second format PPDU is for legacy wireless communication terminal,
wherein a format of a preamble of the first format PPDU is different from a format of a preamble of the second format PPDU,
wherein the first format PPDU and the second format PPDU include a common signaling field, and
wherein the first format PPDU includes a signaling field which is not included in the second format PPDU and is located after the common signaling field.
