Title:
METHOD AND DEVICE FOR GENERATING TRAINING SIGNAL IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/231293
Kind Code:
A1
Abstract:
The present specification relates to a long training field (LTF) symbol of a wireless LAN. An LTF symbol may be generated on the basis of a first LTF generation sequence used for an odd number stream and a second LTF generation sequence used for an even number stream. Number 0 may be configured as an even number element of the first LTF generation sequence, number 0 may be configured as an odd number element of the second LTF generation sequence, a plurality of LTF symbols for first and third streams may be generated by applying a P mapping matrix to the first LTF generation sequence, and a plurality of LTF symbols for a second stream may be generated by applying the P matrix to the second LTF generation sequence.
