Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of disturbance coordination method of sectorization identical networking communication system.
Background technology
In current communication system, according to different network construction forms, identical networking and inter-frequency networking can be divided into; Under inter-frequency networking, different frequency bands is used between different neighbor cells, presence of intercell interference can not be produced, or only have very little presence of intercell interference (interference signal from non-adjacent farther community), but shortcoming is 1/3 or 1/N that each community available bandwidth becomes whole system available bandwidth, generally speaking, although the mode of AF panel is comparatively simple, entire throughput is still affected; And for identical networking, whole system bandwidths between neighbor cell, can be used, band efficiency is far above inter-frequency networking, but presence of intercell interference can become the key factor affecting entire throughput; Especially based in the cellular radio Communication system of OFDM technology, intra-cell users realizes the orthogonal of signal by frequency division multiplexing, to solve the problem of intra-cell interference.But as cost, identical networking can bring stronger presence of intercell interference.Therefore how to reduce presence of intercell interference, become an important subject of wireless communication system.So in order to ensure spectrum transmissions efficiency, improve user performance in community, the communication system of identical networking all needs to adopt interference coordination technique to suppress presence of intercell interference.
Mostly existing interference coordination technique is to carry out AF panel by channeling.Conventional static interference coordination scheme mainly contains FFR (partial frequency multiplexing) and SFR (soft-frequency reuse).It is arrange community forbidding frequency band that FFR calculates ratio juris, and avoids occurring between Cell Edge User mutually to disturb for Cell Edge User distributes the forbidding frequency band of adjacent cell; SFR algorithm principle avoids interference mutually occurs between Cell Edge User by distributing different frequencies and power for the edge customer of neighbor cell.Existing simulation result and document display, static interference coordination scheme can improve the performance of Cell Edge User to a certain extent.
But, in identical networking, according to different antenna configurations, the omnidirectional's co-frequency cell networking using omnidirectional antenna and the sectorization identical networking using directional antenna can be further divided into again.Sectorization identical networking, owing to employing directional antenna, can obtain higher antenna gain, can increase MPS process distance, can improve cell capacity again, thus becomes the main networking mode of wireless communication system in city.
The cell structure of existing exemplary sector identical networking communication system as shown in Figure 1, the coverage of each base station (launching tower pattern) is a regular hexagon region, each regular hexagon region is divided into 3 sectors (for 120 degree of directional antennas in Fig. 1 with dotted line, both each base station was divided into 3 sectors, if 60 degree of directional antennas are then 6 sectors, 180 degree of directional antennas are then 2 sectors, by that analogy).
In order to describe unified and simple for the purpose of, hereafter sector is also referred to as community, the multiple sectors divided under same base station are called that Gong Zhi community is (as in Fig. 1, community 1,4,5 is Gong Zhi community), the interference of adjacent minizone, location is altogether called that common location is disturbed, the sector different from certain sector own base station is called the non-co-located community (as in Fig. 1, community 2,3 is the non-co-located community of community 1) of this sector.
In the system of fig 1, for each sector, respectively there is a set of independently running time-frequency resource, suppress the interference between sector, same location by the directive gain of antenna.And in order to ensure continuous covering, sector intersection still has certain antenna gain, the interference between the multiple sectors under such same base just can not be effectively suppressed.In these interference, be positioned at cell edge, away from this cell base station, the user of (as A point) close to adjacent non-co-located base station, this part user is comparatively large to the interference of non-co-located adjacent cell, and the interference simultaneously self being subject to the edge customer of non-co-located adjacent cell is also larger; And be total to the edge customer of neighbor cell, location, if close to base station, be in center of housing estate (as B point), then it is also larger to the common location interference of adjacent Gong Zhi community, having the greatest impact particularly to the Cell Edge User of adjacent Gong Zhi community because now path loss to the decline of signal much smaller than the decay of directional antenna to signal; Finally, the sector-edge user of neighbor cell, location altogether, if away from base station (as C point), or from two adjacent non-co-located cell edges all close to and away from this cell base station (as E point), or from two adjacent common location cell edges all close to and from this cell base station also close to (as F point), such user may be subject to multiple adjacent cell simultaneously or be subject to the interference of common location adjacent cell and non-co-located adjacent cell simultaneously.
For above-mentioned this sectorization identical networking communication system, what mainly solve due to existing SFR and FFR algorithm is interference problem between non-co-located community, therefore in sectorization identical networking situation, interference between Gong Zhi community does not provide special processing mode, that is, in existing SFR and FFR algorithm, only there is edge customer and central user two kinds classification, for from the closer sector-edge user (as B point user) of this cell base station, when judging user type, according to existing users classification mode, this part user may be judged to be central user (as D point user), this part user is made to obtain interference suppressioning effect.
Although also can by this part user by unified user's screening rule, classify as edge customer, unify according to edge customer (as A point, C point user) process, this part user is enable to obtain interference suppressioning effect, but in fact, this part user is close to this cell base station, only interference is produced to other communities under co-siting base stations, and disturb not quite to the user of non-co-located base station cell, when adopting SFR algorithm, if this part user and edge customer can not be distinguished, and be its allocations of edge frequency band, then both there is no need, also reduce the frequency band transmission efficiency (bps/Hz) of edge customer, because the user that limited frequency band transmits is more, so each user can the speed of average transmission lower, like this, bandwidth assignment targetedly cannot be carried out for the interference feature of user, also just reduce whole band efficiency.
When adopting FFR algorithm, similarly, if it can be used as edge customer process, then too much edge customer makes each community need to mark off more forbidding frequency band could meet QoS requirement, now because forbidding frequency band too much also can cause band efficiency to decline.
In addition, although the overall band efficiency of the relative FFR of SFR is higher, but the interference do not eliminated completely between neighbor cell, only avoid interference the heaviest between neighbor cell, still there is the comparatively minor interference between Cell Edge User and the central user of adjacent cell, interference suppressioning effect is more inferior than FFR.In addition, the division of FFR edge frequency band is more flexible, even if under static frequency configuration, also can divide for edge customer the edge band exceeding whole system bandwidth 1/3, and SFR can only divide the edge band that can not exceed whole system bandwidth 1/3 for edge customer at most.
In a word, existing interference coordination technique cannot be taken into account in the technical indicators such as interference suppressioning effect, band efficiency, frequency band division flexibility simultaneously, can only attend to one thing and lose sight of another.

Fig. 3 is that user's available band of the embodiment of the present invention distributes schematic diagram.
Embodiment
For making object of the present invention, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the present invention is described in more detail.
The present invention is mainly on the frequency band division basis of partial frequency multiplexing technology, superpose the frequency band division of soft-frequency reuse, and user is divided into groups according to annoyance level simultaneously, the maximum user's component of the degree that is interfered is to the forbidding frequency band of partial frequency multiplexing, and the slightly little user's component of the degree that is interfered is to the edge band of soft-frequency reuse; The size of community forbidding frequency band can be reduced under Cell Edge User load identical like this, improve band efficiency again when reducing annoyance level as far as possible simultaneously, both avoid the shortcoming of partial frequency multiplexing and soft-frequency reuse, effectively give play to again respective advantage.
Particularly, the improvement of disturbance coordination method of the present invention mainly at frequency band division, users classification and specifically in the bandwidth assignment three of different user, is illustrated below respectively.
One, frequency band division
For the networking mode of Fig. 1, in the present invention, as shown in Figure 2, Ω is the available total frequency band of whole system in the division of frequency band; 1,2,3 sector0, sector1, sector2 is respectively, the forbidding frequency band of three Ge Gongzhi communities; A, B, C are respectively sector0, sector1, sector2, the edge band of three Ge Gongzhi communities;
Wherein, need to meet following relation between each community forbidding frequency band and edge band:
Common factor is had between two, namely between the forbidding frequency band of each community
Common subset is not had, namely between all forbidding frequency bands
Between the edge band of each community, edge band and this community and and the forbidding frequency band of adjacent cell between all there is no common subset, namely
Can find out, with the frequency band division method shown in Fig. 2, when the edge customer of each community uses the forbidding frequency band of neighbor cell, frequency band pairwise orthogonal staggers; When the edge band of the edge customer use community self of each community, frequency band is also that pairwise orthogonal staggers; Meanwhile, it is also mutually orthogonal staggering between the forbidding frequency band that the edge band of each community and each Cell Edge User use; Like this, as long as edge customer to be distributed in the forbidding frequency band of adjacent cell or any one frequency of edge band, all stagger with the edge customer of adjacent cell is orthogonal on frequency band uses; Difference is, if user is distributed on the forbidding frequency band of adjacent cell, does not so mutually disturb or only very little interference between this user and adjacent cell; And if user is distributed on the edge band of this community, the former is slightly large for the interference ratio so between this user and adjacent cell, but still belongs to less interference; But both common ground there is not mutual interference between the strong interferers between neighbor cell, reach the object suppressing interference preferably.
According to frequency band static division or dynamically divide, above-mentioned edge band and forbidding frequency band can carry out the bandwidth partition of different proportion size; For static division, edge band accounts at most system bandwidth 1/3, and (this is limiting case, for pure soft-frequency reuse, forbidding frequency band is empty), forbidding frequency band accounts at most system bandwidth 1/2, and (this is another limiting case, for pure partial frequency multiplexing, edge band is empty); For dynamic division, then can carry out adaptive distribution according to concrete cell edge and sector-edge user loading condition, bandwidth change is more flexible, as long as ensure between edge band, forbidding frequency band orthogonal, does not carry out expansion describe at this.
Two, users classification
After powering, the regular report measurement information of meeting, in the present invention, can be classified to user by the metrical information of reporting of user user.
Same for the networking mode of Fig. 1, according to the metrical information of reporting of user, user can be divided into following large class:
Away from this cell base station and common location cell edge, the Cell Edge User close to some non-co-located cell edges; Close to this cell base station and common location cell edge, the sector-edge user away from some non-co-located cell edges; Close to common location cell edge and non-co-located cell edge and away from this cell base station, or from two adjacent non-co-located cell edges all close to and away from this cell base station, or from two adjacent common location cell edges all close to and community close to this cell base station and sector-edge user; And, the central user beyond above situation.
In addition, due under the networking mode of Fig. 1, there are two different adjacent Gong Zhi communities (the Gong Zhi community 4,5 as Fig. 1 small area 1) each community, also two different adjacent non-co-located communities (the non-co-located community 2,3 as Fig. 1 small area 1) are had so for Cell Edge User and sector-edge user, according to the how far of user from multiple different non-co-located community, can also be classified in its nearest non-co-located community corresponding for Cell Edge User by Cell Edge User further; As being categorized as Cell Edge User 1 and Cell Edge User 2, respectively in respective cell 1, with community 2,3 nearest Cell Edge User.
In like manner, also according to the how far of user from multiple different Gong Zhi community, can be classified in its nearest Gong Zhi community corresponding for sector-edge user further; As being categorized as sector-edge user 1 and sector-edge user 2, respectively in respective cell 1, with community 4,5 nearest sector-edge user.
Carry out the metrical information of users classification institute foundation, can determine as the case may be, as long as the position relationship between user and this cell base station, neighbor cell can be reflected, relatively typical in Reference Signal Received Power (RSRP), RSRP is that terminal is measured, user can measure a RSRP to each adjacent cell, and reports base station, now can classify according to this metrical information.
Certainly, RSRP is not the direct basis of users classification, and need to be converted to other parameter, concrete example is as follows:
(A) user is distinguished according to pilot to powerratio PPR
Base station calculates PPR (PPR (the i)=RSRP of each user to each adjacent cell
target(i)-RSRP
source(i)), wherein, RSRP
targetfor user is to the RSRP of target serving district, RSRP
source, for user is to the RSRP of this community; I represents different users.
By setting suitable PPR thresholding, according to the PPR of user and comparing of this thresholding, and the user's PPR of each adjacent cell and comparing of this thresholding relatively, users classification can be become above-mentioned a few class, user centered by as larger in PPR, be secondly sector-edge user, less is Cell Edge User, specifically less relative to the PPR of which community according to user, can distinguish further user from which community more close to, thus sector-edge user and Cell Edge User to be distinguished further.
Concrete PPR thresholding can be debugged by emulation and actual field testing and determine.
(B) user is distinguished according to interference power Pinter
Base station calculates the PPR of each user to each adjacent cell, and this user is to the uplink received power Precv of this cell base station.Calculate the interference power Pinter=Precv-PPR of user to each adjacent area;
By setting suitable Pinter thresholding, according to the Pinter of user and comparing of this thresholding, and the user's Pinter of each adjacent cell and comparing of this thresholding relatively, users classification can be become above-mentioned a few class, user centered by as larger in Pinter, secondly be sector-edge user, less is Cell Edge User, specifically less relative to the Pinter of which community according to user, can distinguish further user from which community more close to, thus sector-edge user and Cell Edge User to be distinguished further.
It should be noted that, just lifted the method that two kinds divide user here, also can distinguish user type by other method.
Three, user's bandwidth assignment
Reducing interference to maximize, reasonably distributing different frequency bands according to the type of user, having following principle to bandwidth assignment in the present invention:
1) cell edge, sector-edge user, community and sector-edge user can use the forbidding frequency band of adjacent cell and the edge band of this community.
2) allocation rule of concrete forbidding frequency band is still with reference to the rule of existing FFR, and as Cell Edge User can use the forbidding frequency band of adjacent cell, cell edge and sector-edge user use the common factor of the forbidding frequency band of two neighbor cells.
3) central user can use Whole frequency band bandwidth.
4) preferentially use the forbidding frequency band of adjacent cell to the maximum edge customer that is interfered, just use the edge band of this community when forbidding frequency band and being finished; Because it is minimum forbidding frequency band to transmit the interference be subject to, on edge band secondly.
5), if possible, during the resource as far as possible making each edge customer distribute, frequency band is forbidden in the preferential adjacent area that uses, and secondly uses this utilizing cell edge frequency band.
Like this, concrete bandwidth assignment has following two kinds of roughly allocative decisions at least:
Scheme one: because the size of radius of society, sectorization directional antenna secondary lobe are different with signal attenuation degree dorsad, the interference of Gong Zhi community and the interference size of non-co-located community also may be different, likely the interference of Gong Zhi community generation is larger, and also likely the interference of non-co-located community generation is larger; Therefore Cell Edge User, sector-edge user, community and between sector-edge user, which kind of edge customer interference is maximum is not certain, so at this moment, can according to the equipment of reality and networking situation, determine Cell Edge User, sector-edge user, community and among sector-edge user which kind of be interference large, which kind of interference slightly little; Thus adjacent cell is forbidden band preference and distribute to and be disturbed large edge customer, the edge customer giving interference slightly little this utilizing cell edge frequency band priority allocation; If but respective frequency band in use also has residue, the edge customer so also can distributing to other classes uses.
, in the interference source of non-co-located adjacent cell and location adjacent cell altogether, all there is the difference of strong jamming and slightly weak interference in scheme two: the annoyance level of interference source and interference source have very large relation apart from the how far of this community and aerial angle; So, can in Cell Edge User, sector-edge user, community and distinguish comparatively strong interferers and comparatively two, weak jamming source user class in sector-edge user further, preferentially allow the stronger user of interference use adjacent cell to forbid frequency band, allow the slightly weak user of interference use this utilizing cell edge frequency band; Concrete grammar for the PPR thresholding of above-mentioned differentiation edge customer or interference power thresholding being further divided into the thresholding of two grades, can carry out the differentiation of annoyance level according to this.
Fig. 3 is that user's available band of the embodiment of the present invention distributes schematic diagram, and in this figure, the division of subdistrict frequency band is identical with Fig. 2, and 1,2,3 are respectively sector0, sector1, sector2, the forbidding frequency band of three Ge Gongzhi communities; A, B, C are respectively sector0, sector1, sector2, the edge band of three Ge Gongzhi communities.Wherein, if 1 ', 2 ', 3 ' represent respectively 1,2,3 deduction all common factor parts after residue frequency band;
12represent the common factor frequency band of 1,2, the common factor frequency band of 23 expressions 2,3, the rest may be inferred; Xy represents the union of X, Y common factor frequency band and X ' frequency band, as 1
2the union (being equivalent to 1 frequency band get rid of and 2 parts of occuring simultaneously) that the common factor frequency band of expression 1,2 and 1 ' frequency band form, the rest may be inferred.
As frequency band is expressed as J+K, represent that this user can service band J and frequency band K.
As follows to two kinds of allocative decision concrete examples according to Fig. 3, must be extremely that frequency band is forbidden in Cell Edge User adjacent area for scheme once not limiting, this utilizing cell edge frequency band of sector-edge user.And second more flexible to scheme, can according to the not concrete Resources allocation in user's disturbance source region.
Illustrate, if operational version one, for sector 0 (sector0), be in left lower side and the top right-hand side region (i.e. community and sector-edge user) away from this cell base station, the common factor (frequency band of two adjacent cells forbidding frequency bands can be used
23) and the edge band (A) of this community, the preferential common factor (frequency band using two adjacent cells forbidding frequency bands
23).The user's (i.e. Cell Edge User) being in right hypotenuse and lower edge regions can use the forbidding frequency band of the adjacent cell nearest with it respectively, and (right hypotenuse is near sector2, therefore user can use in the forbidding frequency band of sector2 to get rid of and forbid with this community the part that frequency band occurs simultaneously, i.e. frequency band 3
2; In like manner, below near sector1, therefore user can use in the forbidding frequency band of sector1 the part got rid of and to forbid frequency band with this community and occur simultaneously, i.e. frequency band 2
3) and the edge band (A) of this community, the preferential forbidding frequency band (A) using adjacent cell.And be in left hypotenuse and the user (sector-edge user) of top near this cell base station region can use the forbidding frequency band of the edge band of this community (A) and neighbor cell (left hypotenuse user service band 3 respectively
2, top user's service band 2
3), the preferential forbidding frequency band (A) using adjacent cell.The bandwidth assignment rule that other sector zones of different user uses is identical, repeats no more here.
If operational version two, then at Cell Edge User, sector-edge user community and in sector-edge user, continue to be divided into the large edge customer of annoyance level and the little edge customer of annoyance level according to the size of annoyance level, user is divided as adopted PPR method, then except dividing the PPR thresholding of edge customer, reset a PPR annoyance level thresholding less than above-mentioned PPR thresholding, the edge customer being less than this thresholding is the edge customer that annoyance level is large, the edge customer being greater than this thresholding is the edge customer that annoyance level is little, if and adopt the user classification method of interference power, then same except the interference power thresholding that edge customer is distinguished in setting, reset the annoyance level thresholding larger than above-mentioned interference power thresholding, the edge customer being greater than this thresholding is the edge customer that annoyance level is large, the edge customer being less than this thresholding is the edge customer that annoyance level is little.
When Resourse Distribute, then scheme 2 relative plan 1 is definitely with careful, its main distribution method is identical with such scheme 1, be according to annoyance level when distributing, matched adjacent zone is divided to forbid frequency band to the user priority that annoyance level is large, and then distribute to the little user of annoyance level, the probability that the user that annoyance level is little is assigned to the edge band of this community is larger.
Above-described embodiment is all the networking situation being divided into 3 sectors under each base station is example, for the networking situation of other se ctor partition such as 2,6, the method of concrete frequency band division, users classification, bandwidth assignment is similar, just schematically illustrates no longer one by one here.
From the above embodiments, the disturbance coordination method of this sectorization identical networking communication system of the present invention, by on the frequency band division basis of FFR, superpose the frequency band division of SFR, and simultaneously by Cell Edge User is divided into groups by the disturbed condition be subject to, the user making the degree of being interfered large organizes the forbidding frequency band of priority allocation FFR, and user's component that the degree that is interfered is slightly little joins the edge band of SFR; The size of community forbidding frequency band can be reduced under Cell Edge User load identical like this, improve band efficiency again when reducing annoyance level as far as possible simultaneously, both avoided the shortcoming of FFR and SFR, effectively given play to again respective advantage.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
