The frequency resource allocation method provided by the invention comprises the steps that: a centralized controller determines an interference Small Cell of a Small Cell maintained by the centralized controller when determining that the centralized controller needs to allocate frequency resources to the Small Cell under the control of the centralized controller, and allocates the frequency resources the Small Cell according to frequency resources currently occupied by the interference Small Cell; and the centralized controller notifies the Small Cell of the frequency resources allocated to the Small Cell.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of frequency resource allocation method and device.
Background technology
Flourish along with mobile broadband technology, various intelligent terminal brings the blowout formula of data service to increase.Meanwhile, more and more higher data traffic concentrates on each focus scene of indoor and outdoor.Traditional macro base station encounters the bottleneck of networking and covering, and in order to the degree of depth realizing network covers and capacity boost, consider cost effect, more attentiveness has been turned to small-cell (Small Cell) by operator simultaneously.Small Cell can complete with high quality-of-service and low cost well to provide the requirement of high data rate traffic.
Under the scene of Small Cell identical networking, the dense deployment of Small Cell can cause the distance between adjacent S mall Cell to reduce, and produces serious interference problem thus, reduces the performance of system.To this, effective interference management strategy must be adopted.Adaptive frequency reuse (Adaptive Frequency Reuse, AFR) is a kind of technical scheme recently proposed.In AFR scheme, whole system frequency band is made up of multiple sub-band.For each Small Cell, sub-band three part that band system band is divided into orthogonal subbands, reuse sub-band and prohibits the use.Each Small Cell has one to disturb list, stores and the adjacent S mall Cell oneself having interference relationships.Wherein, the method for building up of interference list is, after Small Cell powers on, by the reference signal strength of other Small Cell of network intercepting (Sniffer) functional measurement, if reference signal strength exceedes the judgement thresholding preset, then this Small Cell is added in interference list.
The implementation procedure of AFR is divided into three steps:
Step one: for the Small Cell mutually disturbed distributes an orthogonal sub-band;
Step 2: being followed successively by Small Cell and distributing multiple orthogonal sub-band, ensureing that the sub-band for there being the Small Cell of interference relationships to distribute is mutually orthogonal simultaneously;
Step 3: by the interference level of restriction adjacent S mall Cell in same frequency band resource, allow adjacent S mall Cell reuse identical sub-band conditionally, thus interference value obtain compromise therebetween in increase band system band utilance and reduction frequency band.
In step 3, for each nonopiate sub-band, if Small Cell needs to assess it as reuse sub-band, on the impact of the snr of received signal of the Small Cell in this Small Cell and its interference list, if received signal to noise ratio in license thresholding, then thinks that it can as the reuse sub-band of this Small Cell.The multiplexing request of frequency resource and response (license or refusal) are realized by the reciprocal process between Small Cell.
In prior art, AFR scheme adopts distributed structure/architecture, and each Small Cell needs with adjacent Small Cell mutual, and like this, when Small Cell quantity is more, mutual between Small Cell then can be very frequent, and transport overhead is larger.
From realization mechanism, the sub-band number that Small Cell can be multiplexing is only relevant with the quality of wireless signal, and not necessarily mates self load or resource user demand.Meanwhile, Small Cell, when request frequency resource multiplex, needs to send a request message to each adjacent Small Cell, only after the multiplexing license receiving each request Small Cell, just can carry out channeling.Like this, extend time not only, and success rate is low.When adjacent S mall Cell number is more, problem is more outstanding.Further, under some complications, such as, a Small Cell, after transmission frequency resource multiplex request message, have received the multiplexing request message of frequency resource that adjacent S mall Cell sends, very complicated and weak effect in realization.
In addition, in prior art, each Small Cell forms respective interference list.Owing to measuring impact such as fluctuation grade, the partial information content of this list may be unidirectional, and namely two Small Cell not interference relationships each other, can not reflect actual interference situation truly.
In sum, prior art is under the intensive identical networking scene of Small Cell, each Small Cell oneself determines the frequency resource needing to take, and safeguards the interfered cell list of oneself separately, therefore there is the problem that interference between adjacent Small Cell is larger.

Embodiment
Embodiments provide a kind of frequency resource allocation method and device, be applicable to the intensive identical networking scene of Small Cell, effectively can reduce the interference between Small Cell.
The embodiment of the present invention based on centralized architecture, as shown in Figure 1.In Fig. 1, M Small Cell is connected with Centralized Controller.Here, Centralized Controller is logical functional entity, can be independently physical equipment, also can close with other physical equipments and establish, such as, can close with arbitrary server of network side and establish.
In the technical scheme that the embodiment of the present invention provides, Centralized Controller is each coupled Small Cell dividing frequency resource.Particularly, in the Small Cell electrifying startup stage, Centralized Controller is that Small Cell distributes initial frequency resource; At Small Cell working stage, Centralized Controller, in conjunction with the disturbed condition of Small Cell Current resource user demand and load condition and adjacent S mall Cell, upgrades the operable frequency resource of Small Cell.In whole process, which frequency resource Small Cell can use be controlled by Centralized Controller completely, and meanwhile, Centralized Controller needs real-time servicing two table: Small Cell interference matrix relation table and Small Cell frequency resource allocation table.
Wherein, Small Cell interference matrix relation table, by the network intercepting of Small Cell and report, and Centralized Controller is determined processes such as reporting the process of content.Particularly, after Small Cell powers on, periodically initiatively intercept the cell signal of peripheral base station, measure the Reference Signal Received Power (Reference Signal Received Power, RSRP) of adjacent S mall Cell and report Centralized Controller.The reporting information of Centralized Controller to Small Cell processes, and generates Small Cell interference matrix relation table.
Exemplarily, a kind of simple processing method can be, if the RSRP measured value of Small Cell to adjacent S mall Cell is greater than pre-determined threshold, then thinks that the two has interference, otherwise, think and do not disturb.The present invention is not restricted concrete judgment criterion.Note Small Cell interference matrix is [I
ij], its building method is: if Small Celli and Small Cellj has interference relationships, or Small Cellj and Small Celli has interference relationships, then I
ij=I
jiput 1, otherwise, I
ij=I
jiset to 0, as shown in Figure 2.
Example matrix is as shown in Figure 2 visible, and Small Cell1 and Small Cell2 and Small Cell3 has interference relationships; Small Cell2 only has interference relationships with Small Cell1; Small Cell3 and Small Cell1 and Small Cell M has interference relationships etc.
The frequency resource that each Small Cell under Centralized Controller administration has distributed is have recorded in Small Cell frequency resource allocation table.Suppose M Small Cell identical networking.In embodiments of the present invention, band system band resource is divided into center frequency-band Bc and edge band Be two parts, and edge band Be is divided into again N number of sub-band, and this N number of sub-band resource is mutually orthogonal.The division number N of edge sub-band is larger, and granularity is less, controls meticulousr, as shown in Figure 3.The size of center frequency-band Bc is by operation and maintenance (Operations & Maintenance, O & M) physical arrangements.Central user equipment preferentially uses center frequency-band resource, when center frequency-band resource is inadequate, can use edge sub-band resource; Edge customer equipment can only use edge sub-band resource.
In embodiments of the present invention, all Small Cell Sharing Centers band resource, different Small Cell occupies identical or different edge sub-band, the Small Cell of mutual interference uses different edge sub-bands as far as possible, and Current resource user demand and the less Small Cell of load use the edge sub-band of fewer number of as far as possible.The load condition of Centralized Controller in conjunction with Small Cell and the disturbed condition of adjacent S mall Cell, the number of the alternative edge sub-band of each Small Cell under its administration of dynamic conditioning and position, to reduce the interference between Small Cell, complete the assigning process of Small Cell edge sub-band.
Concrete frequency resource allocation realization flow as shown in Figure 4, comprising:
Step 1:Small Cell completing after electrifying startup and intercepting reports, to Centralized Controller request dispatching original frequency resource;
Step 2: the Small Cell that Centralized Controller is request dispatching original frequency resource according to the Small Cell interference matrix relation table upgraded distributes one or more edges sub-band;
Step 3: Centralized Controller to this Small Cell resource response allocation result, comprising center frequency-band, with one or more edges sub-band; Afterwards, the resource allocation result that this Small Cell sends according to Centralized Controller enters working stage.
It should be noted that, when subsequent set middle controller is the frequency resource of Small Cell adjustment distribution, without the need to the information of dispatching centre frequency band again, only need the information notifying Small Cell edge sub-band, because the center frequency-band resource that all Small Cell share pre-sets, have adjusted if follow-up, then carry out notifying the center frequency-band resource information after upgrading.
Step 4: Centralized Controller upgrades Small Cell frequency resource allocation table;
Step 5: at working stage, Small Cell periodically carries out resource service condition statistics and report set middle controller;
Step 6: Centralized Controller judgement is the need of distributing new edge sub-band for Small Cell or reclaiming the edge sub-band distributed; If need to distribute or reclaim edge sub-band, the statistical report of Centralized Controller according to Small Cell and the interference matrix relation in conjunction with self maintained and frequency resource allocation table, determine the number and the position thereof that need to distribute or reclaim edge sub-band;
Step 7: if need to distribute or reclaim edge sub-band, Centralized Controller is to Small Cell transmission frequency resource updates Indication message, the alternative edge sub-band information indicating it new, Small Cell carries out UE Resourse Distribute according to the resource allocation result of Centralized Controller;
Step 8: if need to distribute or reclaim edge sub-band, Centralized Controller upgrades Small Cell frequency resource allocation table.
Above-mentioned steps 7 and step 8 are optional steps.
Wherein, the specific implementation in step 7, such as, comprise:
Step one: Centralized Controller starts timer, to the unified process of reporting message of the Small Cell received at run duration at timer; The timing length of timer is configured by O & M, and the transmission delay between Small Cell and Centralized Controller is depended in the setting of this duration;
Step 2: carry this Small Cell Current resource user demand and load condition in the message that Small Cell reports, comprise the UE number, edge UE number, edge Physical Resource Block (the Physical Resource Block that have received, PRB) resources requirement etc., here, particular content is not restricted.The Current resource user demand that Centralized Controller reports according to Small Cell and load condition and the edge sub-band situation of having distributed for this Small Cell, determine whether to need to distribute or reclaim edge sub-band and corresponding edge sub-band number for each Small Cell.
Following table provides a simple example.Suppose that Small Cell Current resource user demand situation is T, preset two resource user demand thresholdings and be respectively the first thresholding TH1 and the second thresholding TH2, TH1<TH2.The edge sub-band number needed in different resource user demand situation is different.
As seen from the above table, finally the 4th can arrange the difference obtained according in table, determine whether to need for Small Cell reallocation edge sub-band, and if desired reallocate edge sub-band time required reallocation edge sub-band number, or determine whether to need to be recovered as the edge sub-band that Small Cell has distributed, and when if desired reclaiming the edge sub-band distributed, the edge sub-band number distributed of required recovery.Such as, if the Current resource user demand T<TH1 of a Small Cell, if then A1-B is greater than zero, determine to need for this Small Cell reallocation A1-B edge sub-band, if A1-B equals zero, then determine not need reallocate for this Small Cell or reclaim edge sub-band, if A1-B is less than zero, then determine that needs recovery has been an absolute value edge sub-band of the A1-B that this Small Cell distributes.TH1≤T<TH2, and the situation of T >=TH2 is in like manner, repeats no more.
Under actual conditions, the judgement of resource service condition also can have other modes, and the embodiment of the present invention does not limit.
Hypothesis set middle controller have received reporting of M Small Cell altogether, wherein, in employing, mode shown in table determines that M1 Small Cell needs to reclaim edge sub-band, M2 Small Cell needs reallocation edge sub-band, and M3 Small Cell neither needs to reclaim does not need allocations of edge sub-band yet; Here, M=M1+M2+M3.
Step 3: suppose when determining to need to carry out edge sub-band resource reclaim to M1 Small Cell, see Fig. 5, adopts following steps to carry out edge sub-band resource reclaim process to this M1 Small Cell:
S501, make m=1;
S502, to need for m the Small Cell discharging edge sub-band, according to the Small Cell interference matrix relation table safeguarded, obtain and have the adjacent S mall Cell of interference relationships gather with this Small Cell, suppose that having L1 disturbs Small Cell; , there is with described m Small Cell the edge sub-band resource shared in this L1 interference Small Cell.
S503, according to safeguard Small Cell frequency resource allocation table, be defined as the edge sub-band that in this L1 Small Cell, each Small Cell has distributed, and add up for each the edge sub-band in these edge sub-bands distributed, add up each edge sub-band to be taken by how many Small Cell, according to the order that statistics is descending, the edge sub-band that these have distributed is sorted, obtains the ranking results of the edge sub-band that these have distributed;
Such as, one Small Cell has 10 to disturb Small Cell, the edge sub-band shared by these 10 interference Small Cell is determined according to Small Cell frequency resource allocation table, such as there are three edge sub-bands, wherein the first edge sub-band is taken by 6 Small Cell in these 10 interference Small Cell, second edge sub-band is taken by 8 Small Cell in these 10 interference Small Cell, 3rd edge sub-band is taken by 3 Small Cell in these 10 interference Small Cell, then ranking results is the second edge sub-band, first edge sub-band, 3rd edge sub-band.If a Small Cell needs release edge sub-band resource, then discharge the second edge sub-band resource, if a Small Cell needs release two edge sub-band resources, then discharge the resource of the second edge sub-band and the first edge sub-band.
S504, according to the form shown in step 2 determine need release edge sub-band number, select the edge sub-band sorting the most forward in described ranking results to discharge successively;
S505, renewal Small Cell frequency resource allocation table;
S506, Centralized Controller are to this Small Cell transmission frequency resource updates Indication message, and the edge sub-band information indicating it available, does not wherein comprise the information of d/d edge sub-band;
S507、m＝m+1；
S508, judge whether m is less than or equal to M1, if so, then forward step S502 to, otherwise, terminate.
Step 4: suppose, when defining M2 Small Cell and needing reallocation edge sub-band, see Fig. 6, to adopt following steps to carry out the reallocation process of edge sub-band resource to this M2 Small Cell:
S601, make m '=1;
S602, Small Cell for the individual edge sub-band of needing to reallocate of m ', according to the Small Cell interference matrix relation table safeguarded, obtain and have the adjacent S mall Cell of interference relationships gather with this Small Cell, suppose to have L2 Small Cell;
S603, according to safeguard Small Cell frequency resource allocation table, determine the edge subband allocation situation of this L2 Small Cell, namely the edge sub-band that this L2 Small Cell takies is determined, add up for each the edge sub-band in the edge sub-band that this L2 Small Cell takies, add up each edge sub-band to be taken by how many Small Cell, according to the sequence that statistics is ascending, the edge sub-band that this L2 Small Cell takies is sorted, obtains ranking results;
S604, for this Small Cell, according to the ranking results of step S603, and need for this Small Cell reallocate edge sub-band number, one or more edges sub-band that selected and sorted result is the most forward from the edge sub-band that this L2 Small Cell takies distributes; Wherein, the edge sub-band number of reallocating for this Small Cell is needed to be determined by step 2;
Such as, 2nd Small Cell has 10 to disturb Small Cell, the edge sub-band shared by these 10 interference Small Cell is determined according to Small Cell frequency resource allocation table, such as there are three edge sub-bands, wherein the first edge sub-band is taken by 6 Small Cell in these 10 interference Small Cell, second edge sub-band is taken by 8 Small Cell in these 10 interference Small Cell, 3rd edge sub-band is taken by 3 Small Cell in these 10 interference Small Cell, then ranking results is the 3rd edge sub-band, first edge sub-band, second edge sub-band.If the 2nd Small Cell needs reallocation edge sub-band resource, then distribute the 3rd edge sub-band resource, if the 2nd Small Cell needs reallocation two edge sub-band resources, then distribute the resource of the 3rd edge sub-band and the first edge sub-band.
