METHOD FOR TRANSMITTING AND RECEIVING FRAME
First Claim
Patent Images
1. A method of transmitting a frame by a device in a wireless communication network, the method comprising:
- generating a first signal field including a symbol having first subcarrier spacing, the first signal field carrying signaling information;
generating a data field including a symbol having the second subcarrier spacing narrower than the first subcarrier spacing, the data field carrying data; and
transmitting a frame including the first signal field and the data field.

Abstract
A frame transmission method is provided by a device in a wireless communication network. The device generates a signal field including a symbol using a 64 FFT and carrying signaling information, and generates a data field including a symbol using a FFT having a larger size than the 64 FFT and carrying data. The device transmits a frame including the signal field and the data field.

8. A method of transmitting a frame by a device in a wireless communication network, the method comprising:
-
dividing a band into a plurality of subbands; transmitting on the band a first part including a legacy preamble compatible with a previous version wireless communication network and a signal field carrying signaling information; and transmitting a second part including a data field carrying data on a corresponding subband among the plurality of subbands. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of receiving a frame by a device in a wireless communication network, the method comprising:
-
receiving a first part having first subcarrier spacing and including a first signal carrying signaling information; decoding a symbol of the first part on a basis of the first subcarrier spacing; receiving a second part having second subcarrier spacing narrower than the first subcarrier spacing and including a data signal carrying data; and decoding a symbol of the second part on a basis of the second subcarrier spacing. - View Dependent Claims (16, 17, 18, 19, 20)
