Research scene positioning in embodiment is as shown in Figure 5A.There are a large amount of Home eNodeB 504 in the range of a macro base station 502.Home eNodeB 504 is according to architectural feature in certain area dense distribution.There is interlaced phenomenon between the efficient communication scope of Home eNodeB 504, as shown in Fig. 5 B, user belongs to HeNB cells when user Ki appears in HeNB cell and other HeNB cells（Such as J₂) interlock position when, user Id will be to HeNB cell J₂Uplink interference is produced etc. HeNB cell.Equally, user K₂Belong to HeNB cell J₂, as user K₂Appear in HeNB cell J₂With other HeNB cells（Such as ^) interlock position when, user K₂Uplink interference will be produced to the HeNB such as HeNB cells cells.As user K₂In HeNB cells not with HeNB cell J₂During position staggeredly, user K₂Also uplink interference can be produced to HeNB cell.

Relevance this feature is had according to interference between HeNB cells, the present invention proposes the definition of up Home eNodeB subgroup and up Home eNodeB group.If Femto cell deployment make it that the isolation between each cell is not so good really, as this CSG for, the interference of up-downgoing all can than larger, so this group and subgroup can also be common to it is descending.

Using the model of this population, network side can with so that implement the radio resource management scenarios of more details（Power Control, the distribution of time-domain and frequency-domain resource）Reach the purpose of interference management.

Define 1. up Home eNodeB subgroups：

When two HeNB cells ^, J₂Between when there is uplink interference, the two HeNB cells are defined as up Home eNodeB subgroup q={ Ji, a J₂} ;As HeNB cell J₃g qJL J₃With in q, J₂In at least one cell when there is uplink interference, q absorbs J₃The new up Home eNodeB subgroup q of formation={ Ji. h. Js define 2. up Home eNodeB groups with such：

When no HeNB cell can be absorbed by up Home eNodeB subgroup q, q at this moment is defined as up family Base station group Q.

Above-mentioned two definition has following characteristic：

The above-mentioned definition of characteristic 1. is directed to uplink interference, and the HeNB cells not having users are not present uplink interference to HeNB cells around, it is temporarily considered as and is not present.By there is the progress of the HeNB cell of user in the structure of up Home eNodeB subgroup and up Home eNodeB group.

Element in the up Home eNodeB subgroup of characteristic 2. and up Home eNodeB group（HeNB cells）It is dynamic.Its element changes with appearing or disappearing for user in HeNB cell.

Can mutually it be converted due to there is the change of user between the up Home eNodeB subgroup of characteristic 3. and up Home eNodeB group.

Characteristic 4. is for the certain amount dense deployment Home eNodeB of determination, and it is the same that the up Home eNodeB group that up Home eNodeB subgroup finally obtains is set up since any one HeNB cell.

To carry out the establishment of up Home eNodeB group, present invention design HeNB state parameters C_Jt ^ P J J₂... J } } HeNB state described.The meaning difference of wherein element is as follows：

S：HeNB working conditions.When having terminal communication in HeNB, labeled as 1;When HeNB endless communicates, S is labeled as 0.

{■Λ'Λ… } :It is up constructed by centered on user Λ_HeNBSubgroup or group member list.

Fig. 6 A show that building up Home eNodeB under dense deployment environment of home base station according to an embodiment of the invention defines 1 and define 2 specific implementation flow chart.

As shown in Fig. 6 A, built according to an embodiment of the invention under dense deployment environment of home base station up Home eNodeB define 1 and define 2 specific implementation flow it is as follows：

Step 601:User confirms working condition with HeNB cells where it, what system marks had users

HeNB cell, initialization array C_Jt = , {J_k^。

Step 602:Each in running order HeNB (^^{= 1}) using the signal intensity of its internal UE measurement surrounding HeNB cell, or pass through HeNB itself module measurement surrounding HeNB signal intensity.

In this step, it can be measured in subscriber terminal side, can also be by the measurement module of base station side（Also referred to as receiver module）Measure, the sensor for being attached to base station can also be used to measure.Base station point group can the path loss based on other base stations to the current base station cell, can also the real-time interference strength based on other base stations to the current base station cell（Signal intensity）. As it was previously stated, the base station can not only include HeNB, it can also actually include Pico cell, RRH etc..And measure the receiving intensity of the signal of adjacent cell Base Transmitter, measurement signal can include CRS (Common Reference Signal), CSI-RS (Channel Status Indication-Reference signal), DMRS (Demodulation Reference Symbol), PSS/SSS (Primary Synchronization Signal/Secondary Synchronization Signal), one kind in PBCH (Physical Broadcast Channel) etc., or more than one.

Specifically, metering system includes：

Option one:Measure and implemented by the measurement module of base station side；

Option 2:Measure and implemented by the user terminal for belonging to the current base station service, and reporting base station.In this case, base station side can select the relevant information of the measured signal of the transmission of neighbor base station notifying user, and auxiliary user measures；

Option 3:Measure and carried out by the sensor for depending on the current base station, base station can learn the measured value of sensor in real time.

For the measuring method of above-mentioned signal intensity, various ways can be taken simultaneously, comprehensively utilize the advantage of different metering systems, and then can both accomplish remaining control, ensure effective collection for the signal intensity, the signal strength data collected is corrected it is also possible to play, it is ensured that the effect of the data precision.

Step 603:For any HeNB J_k, the surrounding HeNB J collected using sensor_mSignal degree ^^ and HeNB J_mState C_Jm = ^,P , {J_mIn^PjTwo signal of change HeNB j_mTo HeNB j_kThe path loss at edge⁷» .If L_M.For HeNB j_mTo the path loss at its efficient communication edge.Work as L_KM<During L, it is believed that HeNB j_kWith HeNB j_mBetween have an opportunity the presence of uplink interference.Update HeNB j_kState parameter

This step is simultaneously independent in running order all HeNB to be occurred.

It should be noted that, if with the presence or absence of interference between judging base station according to signal intensity, the calculating of path loss need not then be carried out, the signal intensity detected and threshold value are compared, it can judge to whether there is interference between base station, specifically, then judge to whether there is the mode of interference including following between base station：

Option one:In network side, by the signal intensity of the neighbor base station of measurement, to judge whether some or some neighbor base stations cause strong jamming to current local area base station or user, if it is, base station subgroup is added, if it is not, Then it is added without base station subgroup；

Option 2:In network side, by the signal intensity of the neighbor base station of measurement, path loss is calculated, judges whether correspondence neighbor base station causes strong jamming to the current base station cell, if it is, base station subgroup is added, if it is not, then being added without base station subgroup.

Step 604:The subgroup information that each HeNB is built is broadcasted in its subgroup or interacts transmission by the wire/wireless link between HeNB.Need to transmit interference information between HeNB, installed because HeNB is the distribution of foundation building, the general HeNB in unified building could constitute intensive deployment, so the HeNB quantity of dense deployment is limited in certain area, the brought data volume of broadcast and time delay will not bring too big workload to system.

Step 605:Each HeNB takes " simultaneously " computing to its own subgroup information and all subgroup information received.There is contact in interference control or be potentially present of the cell combining of contact in a subgroup.

Step 606:Judge whether each HeNB subgroup information is stablized, also changing if up the member of some up HeNB subgroup in HeNB subgroups, jumping to step 604;Immobilized if up each HeNB subgroup members in HeNB subgroups, up HeNB subgroups at this moment are exactly up HeNB groups.

There is provided a kind of distributed control mode in above-mentioned step 605 and step 606, X2 can be passed through between base station, S1 interfaces, or eat dishes without rice or wine, the base station subgroup information list of the subgroup information that interaction is each built, then updating maintenance itself storage.

In addition, a kind of centralized control mode, serving center base stations, or OAM sides are provided in embodiments of the invention, or the subgroup information of respective structure that the network element on other upper stratas is reported by each base station, the interference group information list of each base station of updating maintenance.

Step 607:Up HeNB groups builds completion, and algorithm terminates.

Specific implementation process is as follows：

As shown in Figure 6B, it is assumed that 10 HeNB dense deployments are within the specific limits.Dotted line represents each HeNB efficient communication range boundary, and each HeNB border has sensor each to detect surrounding HeNB signal intensities.The uplink interference or potential uplink interference existed in Fig. 6 B between the overlapping expression HeNB of HeNB efficient communications scope.The cell of grey represents have user to communicate in the cell, and the cell communicated in this figure has： J₂ ,

Wherein J₇There is no communication user in cell, uplink interference will not be produced to HeNB around.

There is the HeNB of user regularly to transmission power test signal around, HeNB J_kOther HeNB (J are gathered using sensor_m) in the power testing signal intensity of this cell edge^Ρ '^»。 HeNB J_kEdge can dispose multiple sensors, take the most strong conduct of signal in multiple sensors^P 。

In fig. 6b, for there is the Home eNodeB of user：

Without loss of generality, present invention assumes that overlapping communications domains situation is as follows in Fig. 6 B：

Have with there is the HeNB of overlapping phenomenon with communication range： J₂;

With J₂The HeNB that there is overlapping phenomenon with communication range has： Ji、 h;

With J₈The HeNB that there is overlapping phenomenon with communication range has： J₉;

With J₉The HeNB that there is overlapping phenomenon with communication range has： J₈、 Jio;

With J₁₀The HeNB that there is overlapping phenomenon with communication range has： J₉。

According to this test data, HeNB state parameter C is updated_Jm ={S,P,{

At this moment each HeNB have updated up HeNB subgroups information according to the overlapping cases of it and surrounding HeNB communication ranges.At this moment J_kThe up HeNB subgroups built are all and J_kIn the presence of direct uplink interference.

Each HeNB broadcasts the subgroup information in its state parameter in its subgroup, while doing " simultaneously " computing to the subgroup information and the subgroup information of itself received, obtains new subgroup information, updates state parameter<.After broadcasting for the first time,

C_j4=(l, ,{J₂,J₃,J₄,J₅,J₆}j . C_j5 =)1, ,{J₄,J₅,J₆}j . c_j6 = \,P ,{J₃,J₄,J₅,J₍
