In order to avoid the interference of minizone, network side is right when dispatching CoMP UE and for its distributing radio resource
CoMP UE cause strongly disturbing neighbor cell to need to keep away in the enterprising professional etiquette of the resource location, i.e., CoMP UE are made
No longer carry out data transmission on the Radio Resource position into strongly disturbing neighbor cell.For convenience,
For evade to CoMP UE disturb Radio Resource be referred to as " alternative resource ", it is occupied, distribute to
UE Radio Resource is referred to as " occupancy resource ", other remaining unappropriated Radio Resources is called " common
Resource ".In order to avoid strong jammings of the CoMP UE by neighbor cell, if serving cell wirelessly provides some
Distribute to CoMP UE in source, then neighbor cell will be kept away in the enterprising professional etiquette of the resource location, i.e. neighbor cell handle
Radio Resource on the position is changed to " alternative resource " from " common resources ".
Fig. 3 is wireless resource allocation methods flow chart provided in an embodiment of the present invention, as shown in figure 3, including with
Lower step：
Step one, determine CoMP UE by strongly disturbing neighbor cell；
Step 2, calculates the interference level that each Radio Resource is subject to；
For on each assignable Radio Resource, i.e., cell " common resources " and on, predict CoMP UE
By the interference level of neighbor cell.
Whether step 3, the interference level that Radio Resource is subject to exceedes thresholding；
When the interference level of Radio Resource exceedes thresholding, into step 4, otherwise into step 5.
Step 4, the Radio Resource can not distribute to CoMP UE；
When Radio Resource interference level exceed thresholding when, illustrate the CoMP UE on the Radio Resource position by
The interference arrived is too big, then can not give CoMP UE by the radio resource allocation.
Step 5, the Radio Resource enters the queue of CoMP UE available resources, row major level sequence of going forward side by side；
When the interference level of Radio Resource is less than thresholding, then need further to be screened, i.e., into CoMP UE
The priority query of available resources, carries out next round priority ranking.It is excellent for entering CoMP UE available resources
The Radio Resource of first level queue, network side searches for alternative resource reusing degree highest radio resource allocation to CoMP
UE.Network side can calculate Radio Resource and be changed into the change total number of alternative resource from common resources in neighbor cell,
And priority ranking is carried out according to this change total number, change total number is smaller, the priority of the Radio Resource
It is higher.
Step 6, gives CoMP UE, neighbor cell is right on the resource location the resource allocation of highest priority
The resource answered is changed into alternative resource from common resources.
According to the output result of step 5, the radio resource allocation of highest priority is given CoMP UE by serving cell,
Meanwhile, the Radio Resource on same asset position is changed to alternative resource by neighbor cell from common resources.
Present invention is mainly applied to CoMP UE interference coordination schemes.For CoMP UE, cooperation cell needs
Avoided on the Radio Resource that CoMP UE launch, to reduce adjacent strong jamming cell to CoMP UE
Interference.
It is below Radio Resource grain with the RBG (Resource Block Group, resource block) in LTE system
Technology explanation is carried out exemplified by degree, but the wireless resource block of the present invention is not limited to RBG.
Network side implements step as follows when dispatching CoMP UE and distributing RBG for it：
Step one, according to the RSRP of CoMP UE this cell measured and the RSRP of neighbor cell, it is determined that pair
CoMP UE cause strongly disturbing neighbor cell list cell, such as the neighboring interfering cell collection caused to it is combined into：
{Cell 1、Cell 2、Cell3…CellK}；
Step 2, is predicted in each assignable RBG resource, CoMP UE are by neighboring interfering cell
Interference level.
On resource block RBG (m), interference level is represented with IL_RBG (m).IL_RBG (m) prediction is handle
Summed by the interference of each neighboring interfering cell.During prediction, if neighboring interfering cell Cell
K resource block m is occupied resource, then neighboring interfering cell Cell k will be on resource block m to CoMP
UE is interfered, and the RSRP for the neighboring interfering cell Cell k that interference level is measured by UE is weighed；
If neighboring interfering cell Cell k resource block m is common resources, then network side thinks that common resources can
To be changed to alternative resource, then just it is considered that neighboring interfering cell Cell k will not be right on resource block m
COMP UE are interfered.
IL RBG (m) are being done interfered cell { Cell 1, Cell 2, Cell3 ... CellK } to RBG (m)
The level of disturbing is summed, and obtains IL_RBG (m).Such as calculate interference level result such as Fig. 4 on each RBG
It is shown.
Step 3, when some RBG interference level exceedes certain thresholding, such as threshold value is Threshold_IL,
That is IL_RBG (m) ＞ Threshold_IL, illustrate that the CoMP UE are too big in the interference that the RBG is subject to, then net
Network side can not distribute to the RBG CoMP UE.
Step 4, in the RBG that interference level is less than thresholding Threshold_IL, i.e. IL_RBG (m)≤
Threshold_IL, then the RBG can enter available resources priority query.The RBG for meeting condition is carried out
Priority ranking.
Step 5, the RBG of the priority query for entering available resources, according to the corresponding N_change of RBG
Size carries out priority ranking.N_change is smaller, and the RBG priority is higher.
N_change definition is to coordinate the CoMP UE if desired, in the neighbor cell of the CoMP UE,
It is changed into the number of alternative resource needs from common resources.
Step 6, according to the output result of step 5, the RBG of highest priority is distributed to CoMP by serving cell
UE, meanwhile, the RBG on same asset position is changed to alternative resource by neighbor cell from common resources.
It is illustrated below：
For serving Cell some CoMP UE, there are RBG 1, RBG 2, RBG in Serving Cell
3rd, 4 RBG such as RBG 4 are common resources.The interfered cell of the CoMP UE be Cell 1, Cell 2,
Cell 3.The distribution of its resource type is as shown in Figure 5.
So in Figure 5, for RBG 1, Cell 1 corresponding is that CoMP UE take resource, Cell 2
Corresponding with Cell 3 is alternative resource, then for RBG 1, if IL_RBG (1) ＞ Threshold_IL,
RBG1 can not enter RBG priority ranking queue.
For RBG 2, Cell 1 and Cell 3 it is corresponding be alternative resource, Cell 2 corresponding is common money
Source.If serving Cell are pre-assigned to CoMP UE in RBG 2, then be accomplished by Cell 2
RBG 2 is changed into alternative resource from common resources.Therefore, for RBG 2, its N_Change size is 1.
Similarly, for RBG 3, if IL_RBG (3) ＞ Threshold_IL, RBG3 can not enter RBG
Priority ranking queue.For RBG 4, its N_Change size is 3.
According to RBG priority ranking principle, RBG 2 highest priority, RBG 4 priority is taken second place.
Therefore, network side needs RBG2 distributing to CoMP UE, meanwhile, Cell 2 is needed RBG2 money
Source Type is changed to alternative resource from common resources.Resource allocation completes the resource type after being changed with resource type
Schematic diagram is as shown in Figure 6.
In summary, the present invention has following technique effect：
The resource allocation that the present invention is optimized to each cell, is not only effectively disturbed CoMP UE
Coordinate, improve CoMP UE handling capacity, moreover it is possible to improve the resource utilization of system, greatly improve system
Overall performance.
Although the present invention is described in detail above, the invention is not restricted to this, the art technology
Personnel can carry out various modifications according to the principle of the present invention.Therefore, all modifications made according to the principle of the invention,
It all should be understood to fall into protection scope of the present invention.
