Disclosed are a method and device for receiving the radio frame. The method comprises: a first functional entity of a station detects that a channel signal intensity reaches a preset threshold, and the first functional entity starts receiving a radio frame and sends an indication that a channel detection result is busy to a second functional entity of the station; the first functional entity determines that the station is not a target station for receiving the radio frame, and sends an indication of ending up receiving the radio frame to the second functional entity; and when transmission of the radio frame ends, the first functional entity sends an indication that the channel detection result is idle to the second functional entity. The disclosure provides a reception operation processing procedure of a station having the function of discarding the radio frame while not updating a network allocation vector (NAV).
