Abstract: A sounding method by a receiving device is provided. The receiving device receives an NDPA frame from a transmitting device, and then receives an NDP frame from the transmitting device. After receiving the NDP frame, the receiving device transmits to the transmitting device a feedback frame including subchannel information measured on a subchannel that is allocated to the first receiving device among a plurality of subchannels into which a predetermined band is divided.

Abstract: A frame transmitting method by a device in a wireless communication network is provided. The device generates a symbol using a part of a plurality of resource units having a different number of tones and transmits a frame including the symbol. A length of symbol duration excluding a guard interval in the symbol is 12.8 μs. The plurality of resource units includes a first resource unit having 26 tones and a second resource unit having 52 tones. Two tones in the 26 tones of the first resource unit are used as pilot tones, and four tones in the 52 tones of the second resource unit are used as pilot tones.
