Title:
METHOD AND APPARATUS FOR GENERATING TRAINING SIGNAL USING PREDETERMINED BINARY SEQUENCE IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/023137
Kind Code:
A1
Abstract:
Disclosed are a method and an apparatus for generating an STF signal usable in a wireless LAN system. The STF signal is included in a field used to improve AGC estimation of a MIMO transmission. A portion of the STF signal is used to transmit an uplink, and can be used for uplink MU PPDUs transmitted from a plurality of STAs. The STF signal that is disclosed, for example, is used for a 40MHz band or an 80 MHz band, is desirably usable for the 40MHz band, and can be generated based on a sequence in which a predetermined M sequence is repeated. The predetermined M sequence can be a binary sequence of which the length is 15 bits.
