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 based on a modulation method of a third symbol after the legacy signaling field and 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 information other than information on the duration of the non-legacy physical layer frame indicates a format of a non-legacy signaling field included in the non-legacy physical layer frame, anddetermine the number of symbols of data of the non-legacy physical layer frame according to a following equation,
