AP0 downlinks and STA2 uplinks can be subject to launch caused interference, although Network Synchronization can avoid the transmitting pair of STA2 uplinks
The strong jamming of STA1 downlink receptions, but interference of the AP0 downlinks to the downlink reception of STA1 can not be avoided, and indoor environment
Under Network Synchronization be also great challenge in itself.
As it can be seen that it presently, there are the demand that interference detecting and interference coordination are carried out for complex network environment.

Some application examples are given below, application scenarios are enhanced ultrahigh speed wireless local area network technology（EUHT）System,
EUHT systems can provide at least handling capacity of 1.2Gbps, to meet requirement of the active user to wireless network data transmission rate.
In EUHT systems, central access point（CAP）Carry out centralized dispatching, scheduling and itself associated website（STA）'s
Uplink and downlink are transmitted.The bandwidth of operation of CAP can be 20MHz, 40MHz or 80MHz, and CAP is by intercepting the institute of available frequency band
There is carrier frequency, select the work subchannel of itself, since the primary bandwidth of subchannel is arranged to 20MHz, the CAP of 20MHz will be selected
Go out 1 work subchannel, the CAP of 40MHz will select 2 work subchannels, and the CAP of 80MHz will select 4 work son letters
Road.The bandwidth of operation of STA can be 20MHz, 40MHz or 80MHz, and after being associated with some CAP, the STA of 20MHz can be stayed
Stay in 1 of CAP work subchannel, the STA of 40MHz may reside within 2 work subchannels of CAP, and the STA of 80MHz can be with
Reside in 4 work subchannels of CAP.
In EUHT systems, CAP will be used as the embodiment of the present invention using as the first node in the embodiment of the present invention, STA
In section point.
In following application example one into application example three, the executive agents of some method and steps can be CAP in itself,
Can be the independent community with CAP homonymies, the executive agent of some method and steps can be STA in itself or same with STA
The independent community of side.Below temporarily by taking CAP and STA are executive agents as an example.
【Application example one】
Method for detecting is disturbed 1~6 to realize as follows in this application example one.
Step 1：CAP receives the channel quality sent with itself associated all STA and indicates（CQI）.
In this step, for currently resident every sub-channels, STA can send corresponding CQI.CQI can have a variety of
Implementation, such as CQI can be modulating-coding index or signal to interference and noise ratio.
Step 2：Transmitted CQI is unsatisfactory for the STA of the first given threshold as sentry STA by CAP.
In this step, the different implementations based on CQI, can set the first different given thresholds, such as current CQI
It is signal to interference and noise ratio, the first given threshold is the value of the signal to interference and noise ratio set, when CQI is higher than first given threshold, table
Show that CQI is poor, be unsatisfactory for the first given threshold.
When at least one CQI that certain STA is sent is unsatisfactory for the first given threshold, which is determined as sentry STA, no
It is to perform the subchannel of interference detecting to meet the subchannel corresponding to the CQI of the first given threshold.
Step 3：CAP dispatches sentry STA and interference detecting is performed within the detecting cycle.
In this step, CAP sends interference detecting instruction to sentry STA, and rising for detecting cycle is carried in interference detecting instruction
Moment beginning and duration and the numbering that perform the subchannel that interference is detected.CAP is within the detecting cycle by pause scheduling sentry STA
Uplink and downlink transmission.
As an alternative embodiment, when the initial time in detecting cycle can be the CAP system synchronous with STA
Between, the duration for detecting the cycle can be the count value of tdd frame cycle or period of sub-frame.
As an alternative embodiment, if the subchannel that perform interference detecting is not carried in interference detecting instruction
Numbering, sentry STA can be carried out interference to currently resident every sub-channels and detect.
Step 4：Sentry STA performs interference detecting within the detecting cycle.
In this step, sentry STA measurement can receive the power for disturbing source signal within the detecting cycle, can also be further
Obtained power measurement values are associated with default level of interference.Here power measurement values or level of interference can serve as referring to
Show the parameter of annoyance level.
Step 5：CAP scheduling sentries STA sends interference detecting result.
In this step, CAP is that sentry STA is distributed and indicated to send the uplink transmission resource of interference detecting result.
Step 6：Sentry STA sends interference detecting result using uplink transmission resource to CAP.
In this step, interference detecting result includes the numbering for performing the subchannel of interference detecting, further includes instruction interference
The parameter of degree.
【Application example two】
On the basis of above application example one, CAP is after the interference detecting result that sentry STA is sent is obtained, Ke Yijin
One step carries out interference coordination, and this application example two provides a kind of method of passive interference coordination, 1~2 realizes as follows.
Step 1：CAP judges whether annoyance level meets default second threshold using the sentry STA interference detecting results sent
Value, if so, performing step 2, does not otherwise perform operation.
In this step, when the parameter for indicating annoyance level is receives the power measurement values of interference source signal, second is preset
Threshold value is performance number, when power measurement values are less than default second threshold, illustrates that annoyance level is unsatisfactory for default second threshold.Again
For example, when the parameter for indicating annoyance level be level of interference, it be grade to preset second threshold, and the is preset when level of interference is higher than
During two threshold values, illustrate that annoyance level is unsatisfactory for default second threshold.
Corresponding annoyance level is unsatisfactory for the subchannel of default second threshold, is known as the son letter of interference coordination to be performed
Road.
Step 2：CAP sends the channel switching command for carrying target subchannel configured information to sentry STA, makes sentry STA
It is switched to target subchannel.
In this step, for CAP in selection target subchannel, there are following several possible situations：
If the first, CAP currently takes more sub-channels and there are other subchannels of not disturbed and non-excess load,
Then using other work subchannels as target subchannel.
For example, the CAP of 40MHz bandwidth of operation currently takes subchannel 1 and subchannel 2, the STA1 of 40MHz bandwidth of operation is stayed
Stay in subchannel 1 and subchannel 2, the STA2 of 20MHz bandwidth of operation is resided in subchannel 2, is detected by disturbing, and CAP is obtained
Know annoyance level that STA1 and STA2 is fed back for channel 2 be unsatisfactory for default second threshold and channel 1 it is current disturbed and
Non- excess load, then the target subchannel that CAP can be using channel 1 as STA1 and STA2, wherein STA1 are also needed the work of itself
Bandwidth changes into 20MHz.
If sub-channels that the secondth, CAP is currently only interfered and the quantity of associated STA are less than default
3rd threshold value, then CAP need all carrier frequency for intercepting other available frequency bands to select available subchannels, which is made
For target subchannel.Further, CAP, which also needs to have associated STA to other except sentry STA, sends channel switching command, makes to own
Associated STA is switched to available subchannels.
【Application example three】
On the basis of above application example one, CAP is after the interference detecting result that sentry STA is sent is obtained, Ke Yijin
One step carries out interference coordination, and this application example two provides the method that two kinds of active interferences are coordinated, and CAP will consult interference with interference source
The mode of coordination.
The first, there are communication interface between CAP.
Except performing the numbering of interference detecting and indicating the ginseng of annoyance level in the interference detecting result that sentry STA is sent
Number is outer, also needs to carry the mark of the CAP as interference source so that can identify by the mark with the associated CAP of sentry STA
Interference source.
The method that the first active interference in this application example two is coordinated 1~2 is realized as follows.
Step 1：CAP sends interference coordination request to interference source.
As an alternative embodiment, interference coordination to be performed can be carried in the interference coordination request of this step
The numbering of subchannel and default interference coordination strategy index, wherein interference coordination strategy are as shown in table 1.
Table 1
| Policy name | Strategy index | Tactful implication |
| Strategy 1 | 00 | Request interference source leaves the channel |
| Strategy 2 | 01 | Downlink and upward cycle duty cycle are lowered to 75% by CAP with interference source |
| Strategy 3 | 10 | Downlink and upward cycle duty cycle are lowered to 50% by CAP with interference source |
| Strategy 4 | 11 | Refusal is coordinated |
Step 2：CAP receives the interference coordination response that interference source is sent.
In this step, interference source receive interference coordination request after, first parse the subchannel wherein carried numbering and
Interference coordination strategy.
If what is carried in interference coordination request is strategy 1, interference source judges that being directed to requested subchannel itself is
The no requirement for meeting to start passive interference coordination, if it is satisfied, the index of strategy 1, table can be carried in interference coordination response
Show and may exit off requested channel, if conditions are not met, the tactful rope of other permissions can be carried in interference coordination response
Draw.
If what is carried in interference coordination request is strategy 2 or 3, interference source can directly receive requested duty cycle
Numerical value is lowered, other duty cycles can also be allowed to lower numerical value, it is assumed for example that the numerical value in current request strategy 2, but can be with
Allow the numerical value in strategy 3.
Step 1 here and step 2 may need to perform repeatedly, until to some interference coordination between CAP and interference source
Strategy is reached an agreement.
Second, communication interface is not present between CAP.
The method that second of active interference in this application example three is coordinated 1~3 is realized as follows.
Step 1：CAP dispatches sentry STA and consults interference coordination mode with interference source within the diplomatic cycle.
In this step, CAP sends the initial time for carrying the diplomatic cycle to sentry STA using sentry STA as diplomatic node
Instructed with duration and the interference coordination of the numbering for the subchannel that perform interference coordination, and the pause scheduling whistle within the diplomatic cycle
The upstream or downstream transmission of soldier STA.
Sentry STA is realized by following sub-step 1~4 consults interference coordination mode with interference source.
Sub-step 1：Sentry STA accesses interference source.
This equivalent to sentry STA perform for interference source networking, after the completion of associated with interference source.
Sub-step 2：Sentry STA sends interference coordination request to interference source.
As an alternative embodiment, sentry STA can be carried in interference coordination request will perform interference coordination
Subchannel numbering and default strategy index, particular content is identical with the first above-mentioned active interference coordination approach.
Sub-step 3：Sentry STA receives the interference coordination response that interference source is sent.
As an alternative embodiment, the numbering for the subchannel that perform interference coordination is carried in interference coordination response
The preset strategy allowed with interference source is numbered.
Sub-step 4：Sentry STA exits interference source.
By above-mentioned 1~sub-step of sub-step 4, sentry STA completes the negotiations process with interference source.
Step 2：CAP scheduling sentries STA sends interference coordination result.
In this step, CAP is that sentry STA is distributed and indicated to send the uplink transmission resource of interference coordination result.
Step 3：Sentry STA sends interference coordination result using uplink transmission resource to CAP.
1~step 3 of above-mentioned steps may need to perform repeatedly, until to some interference coordination plan between CAP and interference source
Slightly reach an agreement.
In the method that second of active interference in this application example three is coordinated, if the interference that sentry STA is sent is detectd
Survey in result and do not carry the mark of interference source, then CAP None- identifieds interference source, as an alternative embodiment, CAP can be with
Dispatch the sentry STA that reported interference detecting result instruction annoyance level is unsatisfactory for default second threshold respectively successively, without
It is this multiple sentry STA of burst schedule.
If carrying the mark of interference source in the interference detecting result that sentry STA is sent, CAP can identify interference source,
As an alternative embodiment, CAP can be unsatisfactory for default the in the interference detecting result instruction annoyance level reported
Two threshold values and interference detecting result for identical subchannel and identical interference source sentry STA in, select any one
Sentry STA consults interference coordination schemes within the diplomatic cycle with interference source.
