Abstract
(EN)
A data transmission method by a station (STA) apparatus of a wireless LAN system is disclosed. A data transmission method by an STA apparatus according to the present invention comprises the steps of: generating a physical protocol data unit (PPDU) including a physical preamble and a data field; determining whether to add a padding symbol to the PPDU; generating and adding the padding symbol to the PPDU if adding the padding symbol is determined; and transmitting the PPDU.
