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.
Claims14
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 and obtains 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, and
- determine the number of symbols of data of the non-legacy physical layer frame according to a following equation,
