Title:
METHOD AND DEVICE FOR TRANSMITTING DATA BASED ON DIFFERENT PILOT TONE PATTERNS IN WIRELESS LAN
Document Type and Number:
WIPO Patent Application WO/2016/085286
Kind Code:
A1
Abstract:
Disclosed are a method and a device for transmitting data based on different pilot tone patterns in a wireless LAN. The method for transmitting data based on the different pilot tone patterns in a wireless LAN may comprise the steps of: an AP transmitting, to a first STA, a first data field generated based on a first pilot tone pattern, from a first frequency bandwidth; and the AP transmitting, to a second STA, a second data field generated based on a second pilot tone pattern, from a second frequency bandwidth, wherein the size of the first frequency bandwidth is n times larger than the size of the second frequency bandwidth, the size of IFFT applied to the first data field and the size of IFFT applied to the second data field are identical, the first pilot tone pattern includes a plurality of first pilot tones, wherein the plurality of first pilot tones are respectively allocated to each of a plurality of first pilot tone indexes, the second pilot tone pattern includes a plurality of second pilot tones, wherein the plurality of second pilot tones are respectively allocated to each of a plurality of second pilot tone indexes, and wherein a portion of the first pilot tone indexes may be identical to the plurality of second pilot tone indexes.
