Document Type and Number:

WIPO Patent Application WO/2020/050680

Kind Code:

A1

Abstract:

A method and a device for transmitting a PPDU in a wireless LAN system are proposed. Specifically, an AP transmits first data through a first band to an STA. The AP transmits a control frame through a second band to the STA while the first data is being transmitted. The AP transmits an NDP through the first band to the STA. The AP transmits second data through the first band to the STA. The AP receives a feedback frame through the second band from the STA while the second data is being transmitted.
