Description

A kind of resource allocation method of Home eNodeB
Technical field
The present invention relates to a kind of resource allocation method of Home eNodeB, exactly, relate in a kind of follow-up evolution LTE-A system of cellular mobile communication Long Term Evolution, newly-built Home eNodeB is by taking different Physical Resource Block PRB(Physical Resource Block) after, interference effect to this residential quarter and adjacent area generation is predicted estimation, PRB is screened and execution priority sequence and selection, thereby not only guarantee the communication performance in this residential quarter, also taken into account simultaneously the adjacent area communication performance after newly-built Home eNodeB is introduced.Belong to the mobile communication technology field.
Background technology
Statistics shows, following 80～90% communication system throughput will occur in indoor and hot spot region.But traditional Cellular Networks technology has the characteristics of " heavy outdoor, gently indoor ", " heavy beehive net, light isolated hot spots " and " heavily mobile switching, gently fix nomadic ", and one of focus of LTE-A system just is being optimized with the focus scene indoor.Under the ordering about of this new demand, introduced a kind of transmitting node less with respect to traditional cell base station transmitting power---Home eNodeB, because the transmitting power of Home eNodeB is little, can be very convenient, flexible for network design, little because of the coverage of this node simultaneously, can utilize more easily the potential high band frequency spectrum of LTE-A.But the introducing of new node can change original topology of networks, makes the presence of intercell interference of this network configuration become a new challenge.
In many systems, channeling mechanism all is considered to a kind of technical measures that realize the high-throughput performance by effective minimizing presence of intercell interference.Under the deployment scenario of traditional wan, frequency distribution, base station location, base station's transmission power and antenna performance etc. can in earlier stage be planned and realize by suitable network.But in the local scene of LTE-A system, it is infeasible that operator carries out the network planning (being spectrum allocation may) to the deployment of Home eNodeB in advance.This is because the deployment of Home eNodeB normally determines by the user is random, therefore, in the deployment of this distributed home base station, the mechanism that a kind of mode with self-organizing of necessary proposition is distributed frequency spectrum resource, improve power system capacity in order to reduce the phase mutual interference of minizone.
In most research, the PRB selection of newly-built Home eNodeB is all the angle from self-interference, and ignored interference to its adjacent area, therefore, how to take into account the performance of above-mentioned two aspects, propose the prioritization scheme of a kind of new PRB, being used for the problem that instructs newly-built Home eNodeB to carry out resource distribution just becomes one of focus that scientific and technical personnel in the industry pay close attention to.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of resource allocation method of taking into account simultaneously the Home eNodeB of this residential quarter and adjacent area transmission performance and signal interference ratio, the method is not only considered the interference of Home eNodeB to this residential quarter, simultaneously by interference prediction, guarantee that the PRB that shares is no more than the setting thresholding to the interference of adjacent area, consider again and take into account the communications performance of this residential quarter and adjacent area, finally realize the prioritization of PRB, be used for instructing newly-built Home eNodeB to carry out resource distribution.
In order to reach the foregoing invention purpose, the invention provides a kind of resource allocation method of Home eNodeB, it is characterized in that: at first Home eNodeB predicts that it takies each Physical Resource Block PRB(Physical Resource Block) rear interference to this residential quarter and adjacent area generation, consider again the maximum interference threshold that this residential quarter and adjacent area allow, judge whether each PRB is available, and try to achieve its corresponding transmitting power on available PRB basis; Then, based on these available PRB transmitting powers, calculate its signal interference ratio in this residential quarter, then according to the signal interference ratio numerical values recited, it is carried out descending, be used for instructing the resource distribution of newly-built Home eNodeB; Described method comprises following operating procedure:

7. method according to claim 1, it is characterized in that: the content of operation of described step (6) comprising:
It is the available PRB prioritization that calculates according to step (5) that the PRB of described local Home eNodeB takies table, and the required PRB number in this residential quarter obtains;
The PRB transmitting power table of described local Home eNodeB is according to selected available PRB, and the transmitting power of determining in corresponding step (4) obtains;
Interference threshold value I in the interference threshold table of described local Home eNodeB max kRepresent that this residential quarter is the interference maximum that can tolerate on the PRB of k in sequence number, this parameter-definition is: if this residential quarter does not take the PRB that this sequence number is k, I max kFor infinity; If this residential quarter takies the PRB that sequence number is k, I max kComputing formula be: Wherein, SIR minSystem parameters for initial setting in step (12): the signal interference ratio lower limit of each PRB;
Threshold value in the interference threshold table of described adjacent area
