Embodiment 1

[0052] According to an embodiment of the present invention, a method for receiving a radio frame is provided, and a receiving operation processing flow of an STA with a function of discarding PPDU without updating NAV is given, thereby realizing a method of giving up receiving PPDU without updating NAV.

[0053] image 3 is a flowchart of a method for receiving a wireless frame according to an embodiment of the present invention, such as image 3 As shown, the method may include the following steps (step S302-step S306):

[0054] Step S302, the first functional entity of the station detects that the channel signal strength reaches a predetermined threshold, the first functional entity starts to receive wireless frames, and sends an indication that the channel detection result is busy to the second functional entity of the station;

[0055] Step S304, the first functional entity determines that the station is not the target receiving station of the wireless frame, and sends an...

Embodiment 2

[0072] According to an embodiment of the present invention, a channel contention access method is provided, which can be used in conjunction with the above-mentioned method for receiving a wireless frame.

[0073] Figure 7 is a flowchart of a channel contention access method according to an embodiment of the present invention, such as Figure 7 As shown, the method may include the following steps (step S702-step S706):

[0074] Step S702, the second functional entity of the station receives the indication of the end of receiving the wireless frame sent by the first functional entity of the station;

[0075] Step S704, the second functional entity determines that the station is not the target receiving station of the wireless frame according to the receiving end indication;

[0076] Step S706, the second functional entity receives the indication that the channel detection result is idle sent by the first functional entity, and if it is necessary to perform channel contention...

Embodiment 3

[0091] According to the embodiment of the present invention, when the wireless station judges that the station is not the receiver of the current wireless frame by detecting the physical frame header of the wireless frame, the wireless station can discard the wireless frame without updating its own NAV, and provides a A method for receiving a wireless frame, the specific method is as follows:

[0092]When the station detects that the channel signal strength reaches the preset threshold, the first functional entity sends an indication that the channel detection result is busy to the second functional entity, and starts to detect the wireless frame physical frame header sequence and signaling indication information. When the station is not the When the target receiving station of the wireless frame, the first functional entity of the station sends a receiving end indication to the second functional entity, and at the end of the wireless frame transmission, the first functional en...

Abstract

The invention discloses a method and device for receiving wireless frames. Wherein, the method includes: the first functional entity of the station detects that the channel signal strength reaches a predetermined threshold, the first functional entity starts to receive the wireless frame, and sends an indication that the channel detection result is busy to the second functional entity of the station; the first functional entity The entity determines that the station is not the target receiving station of the radio frame, and sends an indication of the end of receiving the radio frame to the second functional entity; when the 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. Through the present invention, a receiving operation processing flow of a station having the function of discarding radio frames without updating NAV is provided.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for receiving wireless frames. Background technique [0002] At present, in the wireless network field, the wireless local area network (WLAN for short) develops rapidly, the requirement for WLAN coverage is increasing day by day, and the requirement for throughput is also getting higher and higher. In the Institute for Electrical and Electronic Engineers (IEEE) 802.11 group, a series of the most common WLAN technical standards such as 802.11a, 802.11b, and 802.11g have been defined successively, and other task groups have emerged one after another , is committed to the development of specifications related to the improvement of existing 802.11 technologies. For example, the 802.11n task group proposes high throughput (High throughput, referred to as HT) requirements, introduces multiple input multiple output (Multiple Input Multiple Output, referred to as MI...
