Description
Technical field
The invention belongs to the communications field, relate in particular to network interferences method for detecting and device.
Background technology
Indoor data service accounts for 60% to 80% of whole network data business, therefore mobile communication technology and WLAN (wireless local area network) (WI-FI) technology all focus on application indoor covering, wherein, the cellular technology that flies that covers in faced chamber and access has broad application prospects, for example time-division Long Term Evolution (TD-LTE, Time Division Long Time Evaluation) Femto just belongs to the cellular technology that flies that covers and access in faced chamber.
Due to indoor micro-base station or access point (AP, Access Point) under some scenes, by user, arbitrarily disposed, Virtual network operator cannot suppress isolation by the network planning to be disturbed, make network quality be difficult to guarantee, this is the major technique barrier that restriction at present flies cellular technology large-scale application, is also the key factor that affects WI-FI network quality simultaneously.
It is a kind of conventional interference and insulation method that adjacent micro-base station or AP configure different carrier frequency, and for example, in WI-FI system, after AP start, the automatic frame of meeting is listened all carrier frequency of available frequency band, selects to disturb minimum carrier frequency work, avoids the mutual strong jamming with contiguous AP.
In interference scene as shown in Figure 1, AP1 is positioned at the coverage of AP0, so AP1 can listen to the existence of AP0, and then can select channel and/or carrier frequency with AP0 quadrature, avoids and the mutual interference of AP0 phase, guarantees network quality and capacity.
But this interference and insulation method is not also suitable for interference scene as shown in Figure 2, and solid arrow wherein represents communication link, and dotted arrow represents interfering link.AP1 not in the coverage of AP0, can not listen to the existence of AP0, so AP1 completely likely selects identical channel and/or carrier frequency with AP0, WI-FI network now can be because a plurality of AP competitive channels and blocking communication.For example, AP1 and AP0 work simultaneously, the descending reception of STA1 can be subject to the interference that AP0 downlink and the up transmitting of STA2 cause, although Network Synchronization can be avoided the strong jamming of the up transmitting of STA2 to the descending reception of STA1, but cannot avoid the interference of AP0 downlink to the descending reception of STA1, and the Network Synchronization under indoor environment itself also has challenge.
Visible, there is at present the demand of disturbing detecting and interference coordination for complex network environment.

Step 41: receive the interference that the first node associated with Section Point as sentry's node send and detect instruction.
Step 42: carry out within the detecting cycle and disturb detecting.
Step 43: send and disturb detecting result to first node.
Visible, the embodiment of the present invention provides new interference method for detecting, from the Section Point associated with first node, select sentry's node, scheduling sentry node is carried out and is disturbed detecting within the detecting cycle, and the interference of feeding back by sentry's node detecting result is known situation about being disturbed.
Provide the some application examples that disturb method for detecting in the embodiment of the present invention below, application scenarios is enhancement mode ultrahigh speed wireless local area network technology (EUHT) system, EUHT system can provide at least throughput of 1.2Gbps, to meet the requirement of active user to wireless network data transmission rate.
In EUHT system, central access point (CAP) is carried out centralized dispatching, dispatches the uplink and downlink transmission of the website (STA) associated with self.The bandwidth of operation of CAP can be 20MHz, 40MHz or 80MHz, CAP is by intercepting all carrier frequency of available frequency band, select the work subchannel of self, because the primary bandwidth of subchannel is set to 20MHz, the CAP of 20MHz will select 1 work subchannel, the CAP of 40MHz will select 2 work subchannels, and the CAP of 80MHz will select 4 work subchannels.The bandwidth of operation of STA can be 20MHz, 40MHz or 80MHz, after associated with certain CAP, the STA of 20MHz can reside in 1 work subchannel of CAP, and the STA of 40MHz can reside in 2 work subchannels of CAP, and the STA of 80MHz can reside in 4 work subchannels of CAP.
In EUHT system, CAP is using the first node in the embodiment of the present invention, and STA is using the Section Point in the embodiment of the present invention.
At following application example one to application example three, the executive agent of some method steps can be CAP itself, also can be and the independent community of CAP homonymy, the executive agent of some method steps can be STA itself, can be also the independent community with STA homonymy.Below take temporarily CAP and STA is that executive agent is example.
[application example one]
In this application example one, disturb method for detecting 1 ~ 6 to realize as follows.
Step 1:CAP receives the channel quality indication (CQI) that the STA associated with self sends.
In this step, for current resident every sub-channels, STA can send corresponding CQI.The CQI that STA sends can have multiple implementation, and for example CQI can be modulating-coding index, can be also signal to interference and noise ratio.
The STA that step 2:CAP does not meet the first setting threshold using sent CQI is as sentry STA.
In this step, the different implementations based on CQI, can set the first different setting thresholds, for example current C QI is signal to interference and noise ratio, the value that the first setting threshold is the signal to interference and noise ratio set, when CQI is during higher than this first setting threshold, represents that CQI is poor, do not meet the first setting threshold.
When at least one CQI of certain STA transmission does not meet the first setting threshold, this STA is defined as to sentry STA, the corresponding subchannel of CQI that does not meet the first setting threshold does not disturb for carrying out the subchannel of detecting.
Step 3:CAP scheduling sentry STA carries out and disturbs detecting within the detecting cycle.
In this step, CAP sends interference detecting instruction to sentry STA, disturbs in detecting instruction and carries initial time and the duration in detecting cycle and will carry out the numbering of disturbing the subchannel of detecting.CAP will suspend the uplink and downlink transmission of scheduling sentry STA within the detecting cycle.
As a kind of optional execution mode, the initial time in detecting cycle can be the system time that CAP is synchronizeed with STA, and the duration in detecting cycle can be the count value of tdd frame cycle or period of sub-frame.
As a kind of optional execution mode, if disturbed in detecting instruction, do not carry the numbering that will carry out the subchannel that disturbs detecting, sentry STA can carry out and disturb detecting current resident every sub-channels.
Step 4: sentry STA carries out and disturbs detecting within the detecting cycle.
In this step, sentry STA can measure the power that receives interference source signal within the detecting cycle, also can be further that the power measurement values obtaining is associated with default level of interference.The power measurement values here or level of interference can be as the parameters of indication annoyance level.
Step 5:CAP scheduling sentry STA sends and disturbs detecting result.
In this step, CAP sends for sentry STA distributes and indicates the uplink transmission resource of disturbing detecting result.
Step 6: sentry STA utilizes uplink transmission resource to send and disturb detecting result to CAP.
In this step, disturb detecting result to comprise the numbering of carrying out the subchannel that disturbs detecting, also comprise the parameter of indicating annoyance level.
[application example two]
On the basis of above-mentioned application example one, CAP, after obtaining the interference detecting result of sentry STA transmission, can further carry 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 utilizes the interference detecting result that sentry STA sends to judge whether annoyance level meets default Second Threshold, if so, performs step 2, otherwise undo.
In this step, when the parameter of indication annoyance level is when receiving the power measurement values of interference source signal, default Second Threshold is performance number, when power measurement values is during lower than default Second Threshold, illustrate that annoyance level does not meet to preset Second Threshold.Again for example, when the parameter of indication annoyance level is while being level of interference, default Second Threshold is grade, when level of interference is during higher than default Second Threshold, illustrate that annoyance level does not meet to preset Second Threshold.
Corresponding annoyance level does not meet the subchannel of default Second Threshold, is just called the subchannel that will carry out interference coordination.
Step 2:CAP sends the channel switching command that carries target subchannel indication information to sentry STA, make sentry STA be switched to target subchannel.
In this step, when select target subchannel, there are following several possible situations in CAP:
If the first CAP is current, takies a plurality of subchannels and have not disturbed and other subchannels of excess load not, using these other work subchannels as target subchannel.
For example, current subchannel 1 and the subchannel 2 of taking of CAP of 40MHz bandwidth of operation, the STA1 of 40MHz bandwidth of operation resides on subchannel 1 and subchannel 2, the STA2 of 20MHz bandwidth of operation resides on subchannel 2, by interference, detect, CAP knows that STA1 and STA2 all do not meet the current not disturbed and excess load not of default Second Threshold and channel 1 for the annoyance level of channel 2 feedbacks, CAP can be using channel 1 as STA1 and the target subchannel of STA2, and wherein STA1 also needs the bandwidth of operation of self to change into 20MHz.
If the quantity of the current sub-channels being only interfered of the second CAP and associated STA is lower than default the 3rd threshold value, all carrier frequency that CAP need to intercept other available frequency bands are selected available subchannels, using this available subchannels as target subchannel.Further, CAP also needs to other the associated STA transmitting channel switching commands except sentry STA, makes all associated STA all be switched to available subchannels.
[application example three]
On the basis of above-mentioned application example one, CAP, after obtaining the interference detecting result that sentry STA sends, can further carry out interference coordination, and this application example two provides the method that two kinds of active interference are coordinated, and CAP is by the mode of consulting interference coordination with interference source.
, between CAP, there is communication interface in the first.
In the interference detecting result that sentry STA sends, except carrying out, disturb the numbering of detecting and the parameter of indication annoyance level, also carry the sign as the CAP of interference source, make the CAP associated with sentry STA to identify interference source by this sign.
The method that the first active interference in this application example two is coordinated 1 ~ 2 realizes as follows.
Step 1:CAP sends interference coordination request to interference source.
As a kind of optional execution mode, in the interference coordination request of this step, can carry the numbering of the subchannel that will carry out interference coordination and default interference coordination strategy index, wherein interference coordination strategy is as shown in table 1.
Table 1
| Policy name | Strategy index | Strategy implication |
| Strategy 1 | 00 | Request interference source leaves this channel |
| Strategy 2 | 01 | CAP and interference source are lowered to 75% by descending and upper line period duty ratio |
| Strategy 3 | 10 | CAP and interference source are lowered to 50% by descending and upper line period duty ratio |
| Strategy 4 | 11 | Refusal is coordinated |
Step 2:CAP receives the interference coordination of interference source transmission and replys.
In this step, interference source, after receiving interference coordination request, is first resolved numbering and the interference coordination strategy of the subchannel wherein carrying.
If what carry in interference coordination request is strategy 1, whether interference source judgement meets for asked channel self requirement that starts passive interference coordination, if met, can in replying, carry interference coordination the index of strategy 1, expression can be left asked channel, if do not meet, can carry the tactful index of other permissions in interference coordination replied.
If what carry in interference coordination request is strategy 2 or 3, interference source can directly be accepted asked duty ratio and lower numerical value, also can allow other duty ratio to lower numerical value, for example, suppose the numerical value in current request strategy 2, but can allow the numerical value in strategy 3.
The step 1 here and step 2 may need to carry out repeatedly, until certain interference coordination strategy is reached an agreement between CAP and interference source.
, between CAP, there is not communication interface in the second.
The method that the second active interference in this application example three is coordinated 1 ~ 3 realizes as follows.
Step 1:CAP scheduling sentry STA consults interference coordination mode with interference source within the diplomacy cycle.
In this step, CAP is using sentry STA as diplomatic node, to sentry STA, send the interference coordination instruction of the numbering of the subchannel that carries initial time and the duration in diplomacy cycle and will carry out interference coordination, and within the diplomacy cycle, suspend the upstream or downstream transmission of scheduling sentry STA.
Sentry STA is realized with interference source and is consulted interference coordination mode by following sub-step 1 ~ 4.
Sub-step 1: sentry STA accesses interference source.
This is equivalent to sentry STA and carries out the networking for interference source, associated with interference source after completing.
Sub-step 2: sentry STA sends interference coordination request to interference source.
As a kind of optional execution mode, sentry STA can carry the numbering of the subchannel that will carry out interference coordination and default tactful index in interference coordination request, identical with above-mentioned the first active interference coordination approach of particular content.
Sub-step 3: sentry STA receives the interference coordination response that interference source sends.
As a kind of optional execution mode, in interference coordination response, carry the numbering of the subchannel that will carry out interference coordination and the preset strategy numbering that interference source allows.
Sub-step 4: sentry STA exits interference source.
By above-mentioned sub-step 1 ~ sub-step 4, sentry STA completes the negotiations process with interference source.
Step 2:CAP scheduling sentry STA sends interference coordination result.
In this step, CAP distributes and indicates the uplink transmission resource that sends interference coordination result for sentry STA.
Step 3: sentry STA utilizes uplink transmission resource to send interference coordination result to CAP.
Above-mentioned steps 1 ~ step 3 may need to carry out repeatedly, until certain interference coordination strategy is reached an agreement between CAP and interference source.
In the method that the second active interference in this application example three is coordinated, if the sign of not carrying interference source in the interference that sentry STA sends detecting result, CAP None-identified interference source, as a kind of optional execution mode, CAP can dispatching office reports respectively successively interference detecting result indication annoyance level do not meet the sentry STA of default Second Threshold, rather than these a plurality of sentry STA of burst schedule.
If the sign of carrying interference source in the interference that sentry STA sends detecting result, CAP can identify interference source, as a kind of optional execution mode, CAP can not meet default Second Threshold and disturb in the sentry STA of detecting result for identical subchannel and identical interference source at reported interference detecting result indication annoyance level, selects any one sentry STA and consult interference coordination schemes with interference source within the diplomacy cycle.
