Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Shown in Figure 3, the Forecasting Methodology flow chart of the HII parameter that provides for the embodiment of the invention specifically may further comprise the steps:
Step 301: determine the edge UE in the sub-district.
The method of determining edge UE in the sub-district comprises, (Reference Signal Received Power RSRP) measures to report and determines whether this UE is edge UE according to the ICIC Reference Signal Received Power of UE.
Step 302: the number of determining the required PRB of edge UE that at every turn is dispatched in the sub-district in a period of time.
The number of the required PRB of edge UE that wherein is dispatched to comprises: the number that is assigned with the PRB that the edge UE of resource uses; And/or, be not assigned with the number of the PRB that the edge UE of resource need use.
Step 303: according in this a period of time to the scheduling times of edge UE in the sub-district, and the number of the required PRB of edge UE during each scheduling, the number of the required PRB of calculation plot edge UE, the number of this PRB are the HII parameter information of this sub-district.
In putting for the previous period the update time of each sub-district, wherein should a period of time section long than time update cycle, in this a period of time, calculate in the update cycle, the grade of service according to all edge UE in this sub-district is arranged, according to the order of the edge UE after arranging, according to the information of resource requirement in the state information that reports of each edge UE, the dispatching situation scheduling edge UE of base station itself.Be dispatched to when adding up each uplink scheduling, and the edge UE that has been assigned with resource uses the number of PRB, and be dispatched to when adding up each uplink scheduling but be not assigned to the number of the PRB that the edge UE of resource need use, according to the number of the required PRB of this each edge termination and, and interior scheduling times of this update cycle to edge UE, the number of the required PRB of calculation plot edge UE, the number of this PRB are the HII parameter of this sub-district.For example the edge termination that can dispatch of base station is 500, but the grade of service according to edge UE puts in order, the resource that the base station is occupied can only provide preceding 50 edge UE to use, therefore in the base station during to the edge terminal scheduling, preceding 50 edge UE are scheduled for and resource allocation are arranged, and back 450 edge UE are scheduled for but do not have resource allocation.
Certainly in concrete computational process, also can measure the HII parameter information of sub-district according to a kind of situation wherein, for example only add up that each base station scheduling arrives, and the number of the PRB that the edge UE that is assigned with resource uses, or only add up that each base station scheduling arrives, but the number of the PRB that the edge UE that is not assigned with resource need use, according to the employed PRB of this any situation lower limb UE each accumulation and, reach scheduling times to edge termination, number that can the required PRB of calculation plot edge termination, thus the HII parameter information of sub-district obtained.
In order to make each sub-district when carrying out the indication of HII parameter, HII parameter information to its neighbor cell is had gained some understanding, in embodiments of the present invention, set some update time of each sub-district, put offset the update time of promptly in a update cycle, determining each sub-district HII parameter, wherein, put offset the update time of each sub-district has certain deviant according to time sequencing, this deviant can be the same or different, as shown in Figure 4, for example a update cycle is 30ms, and it is adjacent to have 4 sub-districts, be respectively first, second, third and fourth sub-district, wherein, the update time of first sub-district, to put offset1 be 0ms in first update cycle, and putting offset2 the update time of second sub-district is 7ms, putting offset3 the update time of the 3rd sub-district is 22ms, and putting offset4 the update time of the 4th sub-district is 28ms.In other update cycles, update time, point can conveniently obtain according to the deviant of each minizone.The setting of each cell update time point offset is simultaneously put in offset and the next one update cycle and put offset the update time of first sub-district and do not overlap the update time that needs to guarantee last sub-district in the current update cycle.
Behind the HII parameter information that has obtained the sub-district,, in the PRB of the neighbor cell correspondence of sub-district and this sub-district, select the PRB mark HII parameter of corresponding number according to the number of required PRB.
Wherein in concrete implementation process, can be according to the priority of PRB, select the PRB of corresponding number to carry out the mark of HII parameter, also can from a plurality of PRB, select PRB that should number is carried out the mark of HII parameter arbitrarily.
And according to the priority of PRB, the mark that the PRB of selection corresponding number carries out the HII parameter can comprise that also according to the priority of each PRB, the PRB of selection corresponding number carries out the mark of HII parameter; Or according to each PRB group to priority that should the sub-district, to priority that should the sub-district, carry out the mark of HII parameter according to each PRB in the PRB group.
Wherein for according to each PRB group to priority that should the sub-district, to priority that should the sub-district, carry out the mark of HII parameter according to each PRB in the PRB group.In embodiments of the present invention, at first, according to the number of sub-district and the sub-district that is adjacent, will be divided into to available a plurality of PRB of above-mentioned sub-district and neighbor cell thereof PRB group that should number, wherein the priority of each sub-district of PRB group correspondence is the highest.
For example among Fig. 2,2 adjacent sub-districts, sub-district are sub-district 1,3 and 7, it is adjacent to have 4 sub-districts, be about to a plurality of PRB and be divided into 4 groups, be respectively PRB group, the 2nd PRB group, the 3rd PRB group and the 4th PRB group, wherein the priority of corresponding the 1st sub-district of PRB group is the highest, and the priority of corresponding the 2nd sub-district of the 2nd PRB group is the highest, the priority of corresponding the 3rd sub-district of the 3rd PRB group is the highest, and the priority of corresponding the 7th sub-district of the 4th PRB group is the highest.The priority of each corresponding each sub-district of PRB group can certainly be set according to other corresponding order.
And, the PRB that a plurality of PRB is divided into corresponding all neighbor cell numbers organizes, and can adopt the principle of PRB five equilibrium is divided, and for example the available PRB of all neighbor cells is 30 altogether, wherein there are three sub-districts adjacent, therefore per 10 continuous PRB can be divided into one group.Can certainly divide the highest PRB group of corresponding its priority for each sub-district according to the needed frequency bandwidth of each sub-district loaded service, for example the available PRB of all neighbor cells is 30 altogether, wherein there are three sub-districts adjacent, the frequency bandwidth that one of them sub-district loaded service needs is wide than the frequency bandwidth of other two sub-districts, therefore when dividing, can will be divided into 15 to the PRB that should the highest PRB group of native region priority comprises.
Secondly, according to the highest principle of PRB group priority of each sub-district correspondence, carry out the initialization of HII parameter.
For example have three sub-districts, divide for three PRB groups, wherein the priority of the corresponding PRB group in first sub-district is the highest, and during first cell initial, all PRB mark HII parameters that a PRB is organized are 1, the PRB mark 0 of other PRB groups; During second cell initial, the priority that the 2nd PRB organizes corresponding second sub-district is the highest, and therefore all the PRB mark HII parameters with the 2nd PRB group are 1, the PRB mark 0 of other PRB groups; The initialization procedure of the 3rd sub-district is the same.
As shown in Figure 5,, carry out the indication flow chart of HII parameter, specifically may further comprise the steps for organize the highest method of priority of a corresponding sub-district in the embodiment of the invention according to each PRB:
Step 501: whether the number of judging the required PRB of HII parameter of cell measurement is not more than the number to the PRB in should the native region priority the highest PRB group; If, carry out step 502, otherwise, carry out step 503.
Step 502:, in to should native region priority the highest PRB group,, on the PRB of corresponding number, carry out the mark of HII parameter according to priority to each PRB that should the sub-district according to the number of the required PRB of HII parameter of sub-district prediction.
Step 503: according to priority to PRB group that should the sub-district, judgement is to the number of PRB in should the native region priority the highest PRB group and remove number residue PRB number in the PRB group should the native region priority the highest PRB group and that whether be not less than the required PRB of the HII parameter predicted this sub-district; If, carry out step 504, otherwise, carry out step 505.
Step 504: according to priority to PRB group that should the sub-district, will be in should the native region priority the highest PRB group, according to each PRB to priority that should the sub-district, with all PRB mark HII parameters, except that in to the PRB group should the native region priority the highest PRB group, according to its PRB group to priority that should the sub-district, in each PRB group according to each PRB to priority that should the sub-district, according to priority to PRB group that should the sub-district, according to poor with to the PRB number that comprises in should the native region priority the highest PRB group of the number of the required Physical Resource Block of HII parameter, mark HII parameter on corresponding number PRB.
Step 505: in to should native region priority the highest PRB group, according to each PRB to priority that should the sub-district, mark HII parameter on each PRB.
Measurement, indicating means below by HII parameter among a specific embodiment explanation the present invention.
It is adjacent to have three sub-districts in embodiments of the present invention, be respectively first sub-district, second sub-district and the 3rd sub-district, 50 PRB are example with the 10MHz bandwidth, the the 1st to the 17th PRB is PRB group, the priority of corresponding first sub-district is the highest, and the 18th to the 34th PRB is the 2nd PRB group, and the priority of corresponding second sub-district is the highest, the the 35th to the 50th PRB is the 3rd PRB group, and the priority of corresponding the 3rd sub-district is the highest.
First sub-district is 1 in the value of the HII parameter of the position of the 1st to the 17th PRB during initialization, the value of the HII parameter of other PRB positions is 0, second sub-district is 1 in the value of the HII parameter of the position of the 18th to the 34th PRB, the value of the HII parameter of other PRB positions is 0, the 3rd sub-district is 1 in the value of the HII parameter of the position of the 35th to the 50th PRB, and the value of the HII parameter of other PRB positions is 0.
Update cycle is 20ms, and some update time of first sub-district is offset1, and some update time of second sub-district is offset2, and some update time of the 3rd sub-district is offset3.
In the update cycle before the offset1 of first sub-district, offer in the ICIC RSRP measurement according to all UE in this sub-district and determine whether each UE is edge UE.The required PRB number of edge UE that has been dispatched to during with each uplink scheduling in the time of a update cycle is added up.For example the edge UE to this sub-district has carried out three scheduling in the time of a update cycle, the edge UE that at every turn is dispatched to, and the number of the PRB that this edge UE uses is respectively 8,9 and 10, and wherein this edge UE has been assigned with resource; Simultaneously also statistics be dispatched to but be not assigned with the PRB number that the edge UE of first sub-district of resource need use.In three scheduling for example carrying out in the time of a update cycle, first cell scheduling to but be not assigned with the PRB number that the edge UE of resource need use and be respectively 5,6 and 7.
In three scheduling carrying out in the time of a update cycle, with what be dispatched at every turn, and the PRB number that the edge UE that has been assigned with resource uses adds up, and will be dispatched to but the PRB number that is not assigned with the edge UE of resource and needs add up, calculate two add up and the ratio of the scheduling times that edge UE carried out in update cycle therewith of value, promptly calculate
Promptly the required PRB of this cell edge UE is 15, with the number of this PRB HII parameter as first sub-district.
Simultaneously to being dispatched to, but the PRB number that the edge UE that is not assigned with resource needs is estimated to adopt following method: according to the sounding information of each edge UE, calculate signal to interference and noise ratio (the Signal to Interference plus Noise Ratio of each edge UE, SINR), according to SINR that preserves and channel quality indication (Channel Quality Indicator, CQI) mapping table, search the CQI of this SINR correspondence, with this CQI as the CQI of this edge UE on maximum bandwidth
(UEn)Certainly the base station can require the sounding information of edge UE under maximum bandwidth in the actual calculation process, according to the CQI of sounding information calculations edge UE under maximum bandwidth under this maximum bandwidth
(UEn)Then at CQI based on each edge UE
(UEn)The basis on calculate the average CQI of all edge UE
(ave)After, then according to this average CQI
(ave)And this edge UE that from the information that edge UE reports, obtains all professional data volumes of being carried, calculate the number of the PRB that each edge UE need use.
As shown in Figure 6, wherein the priority of the corresponding PRB group in first sub-district is the highest, the priority of corresponding the 3rd PRB group is minimum, the priority of corresponding the 2nd PRB group in second sub-district is the highest, the priority of corresponding the 3rd PRB group is minimum, the priority of corresponding the 3rd PRB group in the 3rd sub-district is the highest, and the priority of corresponding the 2nd PRB group is minimum.Can certainly stipulate the priority of each corresponding each sub-district of PRB group according to other modes, and stipulate the priority of each sub-district each corresponding PRB in each PRB group, as long as can guarantee that each sub-district is corresponding with a PRB group, this sub-district to should PRB the priority of group the highest, and stipulate each PRB in the highest PRB of this sub-district corresponding priorities group to priority that should the sub-district, opposite with the priority of these each corresponding other sub-districts of PRB.
In order to guarantee to reduce interference among adjacent cells as far as possible, also can adopt the priority difference of each corresponding each sub-district of PRB group simultaneously.For example, the priority that a PRB organizes corresponding first sub-district is 1, and the priority of corresponding second sub-district is 2, and the priority of corresponding the 3rd sub-district is 3; The priority that while the 2nd PRB organizes corresponding second sub-district is 1, and the priority of corresponding the 3rd sub-district is 2, and the priority of corresponding first sub-district is 3; And the priority of corresponding the 3rd sub-district of the 3rd PRB group is 1, and the priority of corresponding second sub-district is 2, and the priority of corresponding first sub-district is 3 etc.Adopt this mode, can effectively avoid the interference among adjacent cells problem.
Be example with Fig. 6 below, the indicating means of HII parameter in the embodiment of the invention is described.
Behind the HII parameter information that obtains first sub-district, at first, because it is the highest that a PRB organizes the User Priority of corresponding first sub-district, and in the PRB group to should the highest PRB of native region priority being 1, what priority was minimum is 17, and according to the number of the needed PRB of this HII parameter, the eNodeB of first sub-district at first predicts resource since a PRB, prediction is continuously and to PRB that should the required PRB number of HII parameter, indication HII parameter on the position of this PRB.For example this HII parameter is 15, and prediction has 15 PRB to need to use, because a PRB is the highest with respect to the priority of first sub-district, and therefore with the 1st to the 15th PRB mark HII parameter in the PRB group, promptly 1.
Yet when the needed PRB number of this HII parameter surpasses the PRB number of the highest PRB group of corresponding first native region priority, and in should all PRB groups of first sub-district, the priority of PRB group be the highest, and the priority of the 3rd PRB group is minimum.
The priority that this moment, the 2nd PRB organized corresponding first sub-district is 2, this moment is when having the PRB residue in should second native region priority the highest the 2nd PRB group, and the number of residue PRB has surpassed the poor of the needed PRB number of HII parameter and the PRB PRB number in organizing, for example second sub-district remains 7 PRB, the PRB that the HII parameter of first sub-district needs is 22, first sub-district during organizing, the PRB that corresponding first native region priority is the highest has PRB17, so just can utilize 5 PRB in the highest the 2nd PRB group of corresponding second native region priority.The priority of corresponding second sub-district is the highest because the 2nd PRB organizes, and that the wherein corresponding second sub-district medium priority is the highest is the 34th PRB, and that priority is minimum is the 18th PRB.When first sub-district utilizes 5 PRB in the 2nd PRB group, according to the 2nd PRB group priority to each PRB that should first sub-district, the priority that the 2nd PRB organizes corresponding first sub-district is that the 18th PRB priority is the highest, the 34th PRB priority is minimum, take 5 continuous PRB successively, with these 5 PRB mark HII parameters.
The eNode B of first sub-district notifies the eNode B of second sub-district and the eNode B of the 3rd sub-district by X2 interface with this HII parameter indication information.
The remaining PRB number of the PRB number and second sub-district that surpasses the highest PRB group of corresponding first native region priority simultaneously when the needed PRB number of this HII parameter, because in all PRB groups that should first sub-district, the priority of the one PRB group is the highest, and the priority of the 3rd PRB group is minimum.When in the highest PRB of corresponding second native region priority this moment organizes, the PRB residue being arranged, but remaining number is less than PRB number poor of the highest PRB group of the needed PRB number of HII parameter and corresponding first native region priority, but when the PRB group that corresponding the 3rd native region priority is the highest has the PRB residue, and the 3rd PRB group that corresponding the 3rd native region priority is the highest and the 2nd the highest PRB of corresponding second native region priority organize remaining PRB number and, surpassed the poor of PRB number that the highest PRB of the needed PRB number of HII parameter and corresponding first native region priority organizes.
5 PRB of the 2nd PRB group residue that for example corresponding second native region priority is the highest, 4 PRB of the 3rd PRB group residue that corresponding the 3rd native region priority is the highest, the needed PRB of HII parameter of first sub-district is 24, the PRB group that corresponding first native region priority is the highest has 17 PRB, so first sub-district need utilize 7 PRB of neighbor cell, and remaining altogether PRB is 9 in the highest PRB group of corresponding second, third native region priority, so first sub-district can utilize second sub-district and the remaining PRB in the 3rd sub-district.
This moment is owing to the priority that the 2nd PRB organizes corresponding second sub-district is the highest, that wherein corresponding second native region priority is the highest is the 34th PRB, that priority is minimum is the 18th PRB, the priority of corresponding the 3rd sub-district of the 3rd PRB group is the highest, that wherein corresponding the 3rd native region priority is the highest is the 50th PRB, that priority is minimum is the 35th PRB, and when first sub-district utilized 7 PRB of second sub-district and the 3rd sub-district, priority the 2nd PRB of corresponding first sub-district group was high than the 3rd PRB group.At first in the 2nd PRB group, because it is the highest that this PRB organizes the priority of corresponding second sub-district, the priority of corresponding first sub-district of each PRB is that the 18th PRB priority is the highest among this PRB, and the 34th PRB priority is minimum, takies the 2nd PRB according to the order of this priority and organizes remaining 5 PRB; And in the 3rd PRB group, because the priority of this corresponding the 3rd sub-district of PRB group is the highest, the priority of corresponding first sub-district of each PRB is that the 35th PRB priority is the highest among this PRB, the 50th PRB priority is minimum, take the 3rd PRB group remaining 2 PRB continuously successively according to this order, with 9 PRB mark HII parameters that take.
The eNode B of first sub-district notifies the eNode B of second sub-district and the eNode B of the 3rd sub-district by X2 interface with this HII parameter indication information.
Simultaneously when the needed PRB number of this HII parameter surpasses the number of PRB in the highest PRB group of corresponding first native region priority, HII parameter when indicating the 18th to the 34th PRB that residue is arranged when second sub-district this moment, when the HII parameter of the 3rd sub-district indicates the 35th to the 50th PRB that residue is arranged, but the remaining PRB number in second sub-district and the 3rd sub-district and poor less than the number of PRB in the highest PRB of needed PRB number of HII parameter and corresponding first native region priority group, for example the needed PRB of HII parameter of first sub-district is 30, the PRB of the first sub-district correspondence is 17, so first sub-district need utilize 13 PRB of neighbor cell, 5 PRB of second sub-district residue, 4 PRB of the 3rd sub-district residue, and second, the 3rd sub-district remaining PRB's and be 9, deficiency offers first sub-district and uses.The base station of first sub-district does not hold over the surplus resources of neighbor cell at this moment, and only that corresponding first native region priority is the highest PRB group is according to the priority of corresponding first sub-district, with each PRB mark HII parameter.
When the base station of second sub-district had obtained its HII parameter information before putting its update time after, when arriving, point carries out the indication of HII parameter in its update time, because the base station of the neighbor cell of second sub-district has all sent to second sub-district with its HII parameter information, therefore the HII parameter information of its neighbor cell can be learnt in the base station of second sub-district simultaneously.
Equally for second sub-district, since the 18th to the 34th PRB promptly the 2nd PRB to organize the priority of corresponding second sub-district the highest, wherein in this PRB group corresponding second native region priority the highest be the 34th PRB, that priority is minimum is the 18th PRB, number according to the needed PRB of this HII parameter, the eNode B of second sub-district according to this PRB group to priority that should the sub-district, at first predict resource since the 34th PRB, prediction is continuously and to PRB that should the needed PRB number of HII parameter, indication HII parameter on the position of this PRB.For example this HII parameter is 15, and prediction has 15 PRB to need to use, and just 25 PRB of the 34th PRB to the is marked the HII parameter in the 2nd PRB group, promptly 1.
Yet when the needed PRB number of this HII parameter surpasses the PRB number of the highest PRB group of corresponding second native region priority, and in should all PRB groups of second sub-district, the priority of the 2nd PRB group be the highest, and the priority of the 3rd PRB group is minimum.When have PRB residue in to should first native region priority the highest the 2nd PRB group this moment, and the number of residue PRB has surpassed the poor of the PRB number of the needed PRB number of HII parameter in organizing with the 2nd PRB.
For example the PRB of the HII parameter of second sub-district needs is 22, during organizing, the 2nd PRB that corresponding second native region priority is the highest has PRB17, residue 7 PRB in first sub-district are so second sub-district just can utilize 5 PRB in the highest PRB group of corresponding first native region priority.Because it is the highest that a PRB organizes the priority of corresponding first sub-district, that the wherein corresponding first sub-district medium priority is the highest is the 1st PRB, that priority is minimum is the 17th PRB, when second sub-district utilizes 5 PRB of first sub-district, the one PRB group is according to priority that should second sub-district, and promptly the highest according to the 17th PRB priority, the 1st PRB priority is minimum, take 5 continuous PRB successively, with these 5 PRB mark HII parameters.
The eNode B of second sub-district notifies the eNode B of first sub-district and the eNode B of the 3rd sub-district by X2 interface with this HII parameter indication information.
Simultaneously when the needed PRB number of this HII parameter surpasses the PRB number of the highest PRB group of corresponding second native region priority, and surpassed PRB number and first sub-district residue PRB number in the 2nd PRB group with, because in all PRB groups that should second sub-district, the priority of the 2nd PRB group is the highest, and the priority of the 3rd PRB group is minimum.When in the highest PRB of corresponding first native region priority this moment organizes, the PRB residue being arranged, but remaining number is less than PRB number poor of the highest PRB group of the needed PRB number of HII parameter and corresponding second native region priority, but when the PRB group that corresponding the 3rd native region priority is the highest has the PRB residue, and the 3rd PRB group that corresponding the 3rd native region priority is the highest and the 2nd the highest PRB of corresponding first native region priority organize remaining PRB number and, surpassed the poor of PRB number that the highest PRB of the needed PRB number of HII parameter and corresponding second native region priority organizes.
For example the needed PRB of HII parameter of second sub-district is 24, the 2nd PRB group that corresponding second native region priority is the highest has 17 PRB, 5 PRB of PRB group residue that corresponding first native region priority is the highest, 4 PRB of the 3rd PRB group residue that corresponding the 3rd native region priority is the highest, so second sub-district need utilize 7 PRB of neighbor cell, and remaining altogether PRB and be 9 in the highest PRB group of corresponding the first, the 3rd native region priority, so second sub-district can utilize first sub-district and the remaining PRB in the 3rd sub-district.This moment is owing to the priority that a PRB organizes corresponding first sub-district is the highest, that wherein corresponding first native region priority is the highest is the 1st PRB, that priority is minimum is the 17th PRB, the priority of corresponding the 3rd sub-district of the 3rd PRB group is the highest, that wherein corresponding the 3rd native region priority is the highest is the 50th PRB, and that priority is minimum is the 35th PRB.When second sub-district utilized 7 PRB of first sub-district and the 3rd sub-district, PRB group was organized the priority height of corresponding second sub-district than the 3rd PRB.At first in PRB group, because it is the highest that this PRB organizes the priority of corresponding first sub-district, the priority of corresponding second sub-district of each PRB is that the 17th PRB priority is the highest among this PRB, and the 1st PRB priority is minimum, takies a PRB according to the order of this priority and organizes remaining 5 PRB; And in the 3rd PRB group, because the priority of this corresponding the 3rd sub-district of PRB group is the highest, the priority of corresponding second sub-district of each PRB is that the 35th PRB priority is the highest among this PRB, the 50th PRB priority is minimum, take the 3rd PRB group remaining 2 PRB continuously successively according to this order, with 9 PRB mark HII parameters that take.
The eNode B of second sub-district notifies the eNode B of first sub-district and the eNode B of the 3rd sub-district by X2 interface with this HII parameter indication information.
Simultaneously when the needed PRB number of this HII parameter surpasses the number of the PRB in the highest PRB group of corresponding second native region priority, HII parameter when indicating the 1st to the 17th PRB that residue is arranged when first sub-district this moment, when the HII parameter of the 3rd sub-district indicates the 35th to the 50th PRB that residue is arranged, but the remaining PRB number in first sub-district and the 3rd sub-district and poor less than the number of the PRB in the highest PRB of needed PRB number of HII parameter and corresponding second native region priority group, for example first sub-district remains 5 PRB, 4 PRB of the 3rd sub-district residue, the needed PRB of HII parameter of second sub-district is 30, the PRB of the second sub-district correspondence is 17, so second sub-district need utilize 13 PRB of neighbor cell, and first, the 3rd sub-district remaining PRB's and be 9, deficiency offers second sub-district and uses.This moment, the base station did not hold over the surplus resources of neighbor cell, and only that corresponding second native region priority is the highest the 2nd PRB group is according to the priority of corresponding second sub-district, with each PRB mark HII parameter.
For the 3rd sub-district, because the priority of corresponding the 3rd sub-district of the 3rd PRB group is the highest, the priority of corresponding the 3rd sub-district of the 2nd PRB group is minimum equally.
And each PRB to priority that should the 3rd sub-district is in the 3rd PRB group, and the 50th PRB priority is the highest, and the 35th PRB priority is minimum; Each PRB to priority that should first sub-district is in the one PRB group, and the 1st PRB priority is the highest, and the 17th PRB priority is minimum, and the priority of corresponding the 3rd sub-district is, the 17th PRB priority is the highest, and the 1st PRB priority is minimum; Each PRB to priority that should second sub-district is in the 2nd PRB group, and the 34th PRB priority is the highest, and the 18th PRB priority is minimum, and the priority of corresponding the 3rd sub-district is, the 18th PRB priority is the highest, and the 34th PRB priority is minimum.
Promptly stored the priority of the PRB group of corresponding each sub-district, wherein each PRB group is corresponding with a sub-district, and is the highest to priority that should the sub-district, and there is a priority orders each each sub-district of PRB group correspondence.And stored the priority of corresponding each sub-district of PRB in each PRB group, when the priority of the corresponding PRB group in sub-district is the highest, the priority of the corresponding described sub-district of PRB in the described PRB group is opposite with the priority of the neighbor cell of corresponding described sub-district.
Under non-three situation of neighbor cell, also there is same indication process between the neighbor cell, here just do not give unnecessary details one by one, believe that those skilled in the art can obtain correct indication process according to foregoing description.
And in the indication process of concrete HII parameter, also can select the PRB of the required PRB number of corresponding HII parameter arbitrarily for use, carry out the mark of HII parameter.
Describe the indication process of HII parameter in this method in detail below by an embodiment, for example above-mentioned to have three sub-districts adjacent, altogether corresponding 50 PRB in these three sub-districts.The PRB that calculates first sub-district required mark HII parameter is 15, the PRB that these 50 PRB need greater than the first sub-district HII parameter, therefore can select 15 PRB mark HII parameters when point arrives arbitrarily when the update time of first sub-district, and the indication information of this HII parameter is sent to the eNode B of second sub-district and the eNode B of the 3rd sub-district by X2 interface.When the HII parameter that calculates second sub-district needs 13 PRB, because the number of remaining PRB is greater than the number of the PRB of HII parameter needs, when the update time of second sub-district, point arrived, from remaining 35 PRB, select 13 PRB mark HII parameters arbitrarily, and the indication information of this HII parameter is sent to the eNode B of first sub-district and the eNode B of the 3rd sub-district by X2 interface.When the HII parameter of calculating the 3rd sub-district needs 10 PRB, this moment, remaining PRB was 22, greater than the number of the required PRB of the 3rd sub-district HII parameter, therefore when the update time of the 3rd sub-district, point arrived, from remaining 22 PRB, select 10 PRB mark HII parameter informations arbitrarily.
When the PRB of the required mark HII parameter that calculates first sub-district is 10, the PRB number of this required mark HII parameter less than the number of the last used PRB in first sub-district and residue PRB number, promptly less than 27, therefore can from these 27 PRB, select 10 PRB mark HII parameters when point arrives arbitrarily when the update time of first sub-district, and the indication information of this HII parameter is sent to the eNode B of second sub-district and the eNode B of the 3rd sub-district by X2 interface.When the HII parameter that calculates second sub-district needs 17 PRB, this moment, the number of remaining PRB was 30,10 PRB that 10 PRB that remove promptly that first sub-district takies and the 3rd sub-district take, and remaining PRB number is greater than the number of the required PRB in this second sub-district, therefore when the update time of second sub-district, point arrived, from remaining 30 PRB, select 17 PRB mark HII parameters arbitrarily, and the indication information of this HII parameter is sent to the eNode B of first sub-district and the eNode B of the 3rd sub-district by X2 interface.When the HII parameter of calculating the 3rd sub-district needs 20 PRB, this moment, remaining PRB was 23, greater than the number of the required PRB of the 3rd sub-district HII parameter, therefore when the update time of the 3rd sub-district, point arrived, from remaining 23 PRB, select 20 PRB mark HII parameter informations arbitrarily.
Certainly the method also can be carried out the mark of HII parameter according to the priority of each PRB.Promptly in the process of mark, at first select the high mark of priority.But adopt this to select arbitrarily to method that should the required PRB number mark of sub-district HII parameter HII parameter, and according to the method for each Physical Resource Block priority, in the PRB number of the HII of the required mark in sub-district parameter more for a long time, certain limitation is arranged, therefore, in the actual calculation process, also can adopt the number division group according to neighbor cell with all PRB, there is certain priority orders each corresponding each sub-district of PRB group, carry out the form that the method for HII parameter mark combines with the PRB of the corresponding number of any selection, perhaps other combining form is as long as can realize indication to the HII parameter.
