1. A wireless communication terminal that communicates wirelessly, the terminal comprising:

  • a transceiver; and

    a processor,wherein the processor is configured to receive a non-legacy physical layer frame by using the transceiver,obtain a legacy signaling field including information decodable by a legacy wireless communication terminal from the non-legacy physical layer frame,obtain length information indicating information on a duration of the non-legacy physical layer frame, from the legacy signaling field,obtain information other than information on the duration of the non-legacy physical layer frame through a remaining value obtained by dividing the length information by a data size transmittable by a symbol of a legacy physical layer frame, wherein the data size transmittable by a symbol of the legacy physical layer frame is 3 octets when a data rate of the legacy physical layer frame is 6 Mbps, anddetermine the number of symbols of data of the non-legacy physical layer frame according to a following equation,
