Abstract
A wireless communication terminal for wireless communication is disclosed. The wireless communication terminal includes: a transceiver; and a processor. The processor is configured to transmit a non-legacy physical layer frame including a legacy signaling field including information decodable by a legacy wireless communication terminal by using the transceiver.

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, and
- determine the number of symbols of data of the non-legacy physical layer frame according to a following equation,
