    • Disclosed are a method and an apparatus for transmitting a frame in a wireless LAN. The method for transmitting a frame in a wireless LAN may comprise: a step in which an AP transmits an RTS frame for protecting a medium to an STA; a step in which the AP receives a CTS frame from the STA in response to the RTS frame; and a step in which the AP transmits a data frame to the STA in response to the CTS frame, wherein the RTS frame is included in a first PPDU which is generated on the basis of a first IFFT size, the data frame is included in a second PPDU which is generated on the basis of a second IFFT size, the second IFFT size is greater than the first IFFT size, and the data frame can be transmitted on the basis of a transmission-range-determining parameter which is determined on the basis of the difference between the second IFFT size and the first IFFT size.
    • 公开了一种用于在无线LAN中发送帧的方法和装置。 用于在无线LAN中发送帧的方法可以包括:AP向STA发送用于保护媒体的RTS帧的步骤; AP的响应于RTS帧从STA接收CTS帧的步骤; 以及AP响应于CTS帧向STA发送数据帧的步骤,其中RTS帧被包括在基于第一IFFT大小生成的第一PPDU中,数据帧被包括在 第二PPDU,其基于第二IFFT大小生成,第二IFFT大小大于第一IFFT大小,并且可以基于在基础上确定的传输范围确定参数来发送数据帧 的第二IFFT尺寸和第一IFFT尺寸之间的差异。
