The technology of net.
Currently, 802.11 research for having set up Wireless Fidelity of future generation (Wireless Fidelity, Wi-Fi) technology
Group --- efficient WLAN (High Efficiency WLAN, HEW), to improve the handling capacity of Current wireless communication.By
In HEW application scenarios than the more crypto set in existing standard, so forming overlapping basic service set (Overlapping
Basis service set, OBSS) probability increase, in order to reduce the possibility to form OBSS, prior art proposes one kind
Change clear channel assessment (CCA) (clear channel assessment, CCA) mechanism, i.e., dynamically change the sensitive of receiver
Degree.
If there is new site STA (supporting dynamic to change the website of receiver sensitivity) in certain region
And old STA (website for not supporting dynamic to change receiver sensitivity), then CCA mechanism is used in region, always
The interference that is subject to of STA it is bigger than the probability of the new STA interference being subject to, access point and station in the prior art as shown in Figure 1
The communication scheme of point, the signal intensity that site STA 1 mutually receives with site STA 2 is -70dbm, access point AP1, access
The signal intensity that point AP2 is respectively received STA1, STA2 is -50dbm, if STA1 supports dynamic, change receiver is sensitive
Degree, and STA2 does not support to support that dynamic changes receiver sensitivity, then when STA1 communicates with AP1, STA2 can not then lead to AP2
Letter because perceiving channel busy according to CCA mechanism STA2, and STA1 then will not, this machine for changing receiver sensitivity
System just brings unfairness, has had a strong impact on the service efficiency of frequency spectrum, and reduce the handling capacity in region.
