Abstract: 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).

Abstract: Disclosed are a method and system for accessing a wireless channel. An access point transmits a radio frame including access parameters of at least one group of stations (STAs); and when receiving the radio frame, an STA belonging to the at least one group of STAs transmits data to be transmitted competitively within an uplink transmission period in the access parameters according to the access parameters of the group of STAs. With the disclosure, system overhead can be reduced while low power consumption of a station is ensured.
