Abstract
Disclosed are a method and apparatus for generating a short training field (STF) sequence that can be used in a wireless LAN system. The STF signal is included in a field used to improve AGC estimation of MIMO transmission. Some of the STF signals may be used for uplink transmission and may be used for uplink MU PPDU transmitted from a plurality of STAs. For example, the STF signal is used for an 80 MHz band or a 160 MHz band and may be generated based on a sequence having a preset repeated M sequence. The preset M sequence may represent a binary sequence of a length having 15 bits.
