Description

A kind of MRP, distribution method and device

Technical field

The present invention relates to communication technical field, relate in particular to a kind of MRP, distribution method and device.

Background technology

Concentrate Inter-Cell Interference Coordination (ICIC) technology to coordinate each Cell Edge User device resource by newly-increased centralized control node, reach the object of avoiding or alleviating edge customer equipment interference between neighbor cell.At present, concentrate ICIC technology to exist edge customer device resource requirements to estimate inaccurate, when actual schedule, may occur that the edge customer device resource of some subframe planning is by central user hold facility, the edge customer equipment of some subframe may take again more central user device resource position, cause phase mutual interference between each Cell Edge User equipment, can not reach the effect of the Inter-Cell Interference Coordination of expection.

Concentrate ICIC technology at Long Term Evolution (Long Term Evolution, LTE) newly-increased centralized control node in network, edge customer device distribution and information on load that centralized control node reports according to each community, focus on and coordinate the edge customer device resource of each community, thereby make Radio Resource reasonably distribute in minizone and cooperate, better control the interference level of whole net, improve the performance of cell edge and community entirety.

Existing scheme is described below:

Reporting subdistrict, each base station edge customer device resource requirements and interference Neighboring Cell List, the edge customer device resource requirements amount here, can predict according to the spectrum efficiency of the assurable bit rate of edge customer equipment (Guaranteed Bit Rate, GBR) or non-assurance bit rate (NGBR) speed and edge customer equipment:

$R_d=\frac{{\mathrm{Num}}_{\mathrm{PRB}\_d}}{R_{\mathrm{SBR}\_D}}\×\underset{i=1}{\overset{\mathrm{Kd}}{\mathrm{\Σ}}}{R}_{d,i}^{\mathrm{req}}$

Wherein:

R _dfor the edge customer device resource requirements amount calculating, characterize with Physical Resource Block (Physical Resource Block, PRB) number.

Num _{pRB_d}for example, for the descending all existing PRB numbers that take in average each chronomere (frame) in a load measurement period that are carried on of edge customer equipment.

R _{sBR_d}for the total active service speed of the descending all existing carryings of edge customer equipment.

it is the bearer rate requirement of a downlink bearing.Downlink bearing rate requirement is GBR speed or minimum bit rate (MinBR) speed.

Kd is in the time that load measurement period arrives, the descending also carrying number that exist and that have rate requirement of edge customer equipment.If Kd is 0, R _dbe 0.

Centralized control node, according to each base station reporting information, is determined the spendable PRB resource location of each Cell Edge User equipment according to certain algorithm, and the edge customer equipment PRB quantity of each plot planning equals the edge customer device resource requirements of this community.Basic thought is to allow the resource location of edge customer hold facility of the community that has interference relationships not overlapping as far as possible, assurance exists the minizone edge customer equipment of interference relationships not disturb mutually, if cannot accomplish completely not overlappingly, it be just the PRB resource location of the edge customer equipment selection minimum interference of each community.

Dispatch according to the edge customer device resource position of centralized control node indication Dui Ge community, base station.When scheduling, be followed successively by user equipment allocation resource according to dispatching priority queue, central user equipment preferentially takies center P RB resource (non-edge customer equipment PRB resource location), if resource not also can take edge customer device resource; Edge customer equipment preferentially takies edge PRB resource, if resource not also can take central user device resource.

But prior art scheme has the following disadvantages:

First, when being each cell allocation edge customer equipment available resources, centralized control node only considers basic service quality (the Quality of Service of this Cell Edge User equipment, QoS) demand, for NGBR, its MinBR demand has only been considered in carrying, and in real network when operation, is in order to receive more users equipment that less MinBR generally can be set, so the service rate of NGBR carrying actual motion is probably greater than MinBR.Centralized control node is the PRB occupancy that the edge resource of edge customer facility planning is just less than edge customer equipment actual schedule needs like this, in the time of actual schedule, because the edge resource that centralized control node is distributed is not enough, edge customer equipment can take more non-edge customer device resource position, the edge customer equipment of this community can be subject to larger interference on the one hand, also can cause interference to the edge customer equipment of other communities on the other hand, can not reach the effect of each Inter-Cell Interference Coordination of expection.

In addition, each community can not guarantee that every subframe can be dispatched to edge customer equipment and central user equipment, also its resource occupation situation is not obligated when control centre or edge customer equipment simultaneously, edge customer equipment also can take center resources, and central user equipment also can take edge resource.Like this, in the time there is a large amount of high priority central user equipment in scheduling queue, just there will be central user equipment to seize the situation of edge customer device resource, otherwise, in the time there is a large amount of high priority edge customer equipment in scheduling queue, just there will be edge customer equipment to seize the situation of central user device resource, can not guarantee that so on the whole the edge resource of planning is by edge customer hold facility, be unfavorable for controlling the interference between each Cell Edge User equipment, can not guarantee edge customer appliance services speed.

with interference Neighboring Cell List.

17. base stations according to claim 16, is characterized in that, described allocation units specifically for:

When to each cell scheduling, be followed successively by user equipment allocation resource according to priority query, wherein, the schedulable PRB limited amount of central user equipment configures in centralized control node when PRB resource selection, preferentially take central user equipment PRB resource, exceed part and take edge customer device resource,

after using, will treat that control centre's subscriber equipment temporarily puts into central user device waiting queue; The schedulable PRB limited amount of edge customer equipment configures in centralized control node

when PRB resource selection, preferentially take the edge customer device resource of planning, exceed part and take central user device resource.

18. base stations according to claim 17, is characterized in that, described allocation units also for:

If a complete system of all edge customer equipment schedulings of subframe remains PRB resource in addition, continue as the central user devices allocation residue PRB resource in central user device waiting queue.
