The station obtains a transmission opportunity (TXOP) for a bandwidth, the TXOP indicating an interval of time during which the station has a right to initiate frame exchange sequences onto wireless medium. The station sets a transmit bandwidth parameter of a non-initial physical layer protocol data unit (PPDU) of a plurality of PPDUs to be transmitted during the TXOP based on a transmit bandwidth parameter of a preceding PPDU of the plurality of PPDUs. The transmit bandwidth parameter of the non-initial PPDU is set to be same or narrower than the transmit bandwidth parameter of the preceding PPDU. A bandwidth indicated by the transmit bandwidth parameter of the non-initial PPDU or the preceding PPDU includes at least one of 20 MHz, 40 MHz and 80 MHz. The station transmits the non-initial PPDU during the TXOP."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting data frame in WLAN system","description":"A method is provided for transmitting a data frame by a station in a wireless local area network.
