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.
Claims14
A method of transmitting a frame by a device in a wireless communication network, the method comprising:
- generating a symbol using a part of a plurality of resource units having a different number of tones, a length of symbol duration excluding a guard interval in the symbol being 12.8 μs;
- and
- transmitting a frame including the symbol,
- wherein the plurality of resource units includes a first resource unit having 26 tones and a second resource unit having 52 tones, and
- wherein 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.
A method of receiving a frame by a device in a wireless communication network, the method comprising:
- receiving a frame including a symbol, a length of symbol duration excluding a guard interval in the symbol being 12.8 μs;
- and
- decoding data included in a part of a plurality of resource units having a different number of tones, from the symbol,
- wherein the plurality of resource units includes a first resource unit having 26 tones and a second resource unit having 52 tones, and
- wherein 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.
