Detailed description of the invention

For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with this Accompanying drawing in bright embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention, Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise The every other embodiment obtained, broadly falls into the scope of protection of the invention.

Traditional cordless communication network is formed same by the BS that service rate and transmit power are same or like The structure of network forming network, such as with BS as network in infrastructure cellular network in, generally by operator Large scale deployment BS, meets the covering demand of Outdoor Network, along with portfolio in cordless communication network With the increase of type of service, and the lifting of service rate, the bulk transaction of multimedia service and low strap Contradiction between the wireless channel of wide, high bit-error constitutes huge challenge to wireless communication transmissions；Cause This, traditional cellular network can not meet these requirements.Heterogeneous network becomes the above-mentioned business of solution One effective ways of demand, hierarchical network architecture and polytype network element of heterogeneous network can be more preferable Adaptation and mate following diversified business demand, it is achieved load balancing and service distributing, cleverer Live and use resource efficiently, strengthen the elasticity of network, preferably promote the service quality of user, it is achieved with To subscriber equipment, (User Equipment is referred to as: the network centered by UE) network centered by BS Transformation.

It is above-mentioned it is stated that interference management and control can be carried out by ICIC in traditional cellular network System, ICIC includes above-mentioned partial frequency multiplexing, soft-frequency reuse and full rate multiplexing from resource coordination mode Three classes.Specifically, such as in LTE system, ICIC measurement includes the measurement of up-downgoing, the most up Measurement is identified with HII and OI instruction, and descending measurement has RNTP to indicate, and can pass through evolved base station (Evolved Node B referred to as: the X2 interface between eNodeB), transmits up strong jamming instruction Device (High Interference Indicator, referred to as: HII) and overload indicator (Overload Indicato, Referred to as: OI) instruction, and descending Relative Narrowband TX Power (Relative Narrowband Transmission Power, referred to as: RNTP) instruction, this community eNodeB is little by the neighbour received HII, OI and RNTP instruction that district eNodeB sends, it is judged that the Resource Block (Resource of uplink and downlink Block, referred to as: RB) whether can use, and specifically used mode.

For example, in the downlink, ICIC is mainly realized by RNTP, and RNTP indicates main Determine when being used for dispatching that the edge UE of community uses the edge UE of which RB, Ji Zhe community to make as far as possible Being indicated to, with this community, the RB that adjacent cell RNTP is 1, do not use adjacent cell instruction RNTP is 1 as far as possible RB, RNTP be when 1, to indicate the currently used RB in this community.Mutual by between eNodeB, Travel through all RB that adjacent Liang Ge community is used, determine that the resource that each eNodeB can use is entered Row scheduling.The interference control method carried out by ICIC, can solve in macrocellular that between neighbor cell edge The interference problem of UE, but it cannot be guaranteed that network system has higher performance；Especially, when community During edge UE negligible amounts, relative signaling consumption is the biggest；Owing to ICIC algorithm mainly solves little Area edge UE experienced interference problem, does not therefore have the interference of whole UE in considering cell coverage area Problem.

Wherein, the d in above-mentioned (1-1) formula_p,jFor Femtocell_jIn the 2nd BS and UE_pBetween distance, f_cFor carrier frequency, the carrier frequency of the 2nd BS is determined by the carrier frequency point of himself, d₀For reference distance, Generally taking 1m, c is constant, the specially light velocity.Can obtain accessing Femtocell by (1-1) formula_j's UE_pAt RB_iOn the power P that receives_j,iFor:

$P_{j,i}=P_F\·{\left|h_{f_j,i}\right|}^2\·{\mathrm{\ζ}}_{p,j}---(1-2)$

Wherein, the P in above-mentioned (1-2) formula_FFor Femtocell_jIn the transmit power of the 2nd BS, h_fj,iIt is Two BS are at RB_iOn Rayleigh fading.

With above-mentioned (1-2) formula it is likewise possible to obtain UE_pReceive from Macrocell at RB_iOn Interference signal power P_macro,iFor:

Wherein, the P in above-mentioned (1-3) formula_MIt is the transmit power of a BS, h_macro,iIt is that the 2nd BS exists At RB_iOn Rayleigh fading,For UE_pAnd the path loss between a BS.Thus according to above-mentioned (1-1) formula can calculate the SINR in above-mentioned (1) formula to (1-3) formula_j,i, particularly as follows:

${\mathrm{SINR}}_{j,i}=\frac{P_{j,i}}{\underset{k=1,k\≠j}{\overset{M}{\mathrm{\Σ}}}{P}_{k,i}+P_{\mathrm{macro},i}+N_i}---(1-4)$

Wherein, the N in above-mentioned (1-4) formula_iFor this UE_pAt RB_iOn the power of white Gaussian noise, should (1-4) formula can calculate access Femtocell in substituting into (1) formula_jUE_pAt RB_iOn maximum transmitted Speed C_p,i。

It should be noted that by (1) formula specifically get be access Femtocell_jEach UE exist Peak transfer rate on each RB；To obtain this Femtocell_jIn the 2nd BS on each RB Peak transfer rate, then the 2nd BS can by receive access this Femtocell_jEach UE often Peak transfer rate on individual RB, by this Femtocell of access_jThe maximum transmitted measured by all UE speed Rate collects, thus obtains this Femtocell by chance algorithm_jIn the 2nd BS on each RB Peak transfer rate, to access this Femtocell_jUE be to be explained as a example by ε, this Femtocell_j? RB_iOn peak transfer rate constitute set in, the number of element is ε, specially C_1,i,C_2,i,…C_ε,i, Define this Femtocell_jAt RB_iOn peak transfer rate μ_j,iFor:

μ_j,i=max{C_p,i| p=1,2 ... ε } (C_p,i≥0) (2)

Wherein, the j in above-mentioned (2) formula is Femtocell_jCorresponding label, i is RB_iCorresponding label, This Femtocell is accessed when there is no UE_jTime, μ_j,i=0；Be may determine that by above-mentioned (1) formula and (2) formula Go out Femtocell_jIn the 2nd BS peak transfer rate on each RB；Model is covered for a BS Enclose other interior Femtocell_kFor (k ≠ j), again may be by aforesaid way and obtain each Femtocell In the 2nd BS peak transfer rate on each RB, then the receiver module 11 of a BS can With the 2nd BS each in receiving BS coverage peak transfer rate on each RB.

Receiver module 11, each UE being additionally operable to be accessed a BS by reception is recorded on each RB Peak transfer rate, obtain BS peak transfer rate on each RB.

In the present embodiment, for the BS in Macrocell, a BS obtains himself The maximum biography that peak transfer rate on each RB and above-mentioned 2nd BS are obtained from each RB The mode of defeated speed is identical, and each UE accessing a BS is calculating this UE at each RB On peak transfer rate time, again may be by measuring this UE SINR on each RB and count Calculate, concrete mode and the side of the result of calculation above by (1-1) formula to (1-4) formula acquisition (1) formula Formula is similar to, therefore does not repeats them here；Difference is, each UE that a BS passes through to access is each After the peak transfer rate recorded on RB, it is not necessary to be sent to other BS, a BS will obtain After each peak transfer rate taken collects, obtain a BS at each RB by chance algorithm On peak transfer rate.

Computing module 12, for calculating the maximum overall transmission rate of each RB, each RB's is maximum total Transfer rate is that each 2nd BS peak transfer rate on each RB and a BS are at each RB On peak transfer rate sum.

In the present embodiment, the BS each 2nd BS in getting its coverage is each After peak transfer rate on RB, and the peak transfer rate that a BS is on each RB, The maximum overall transmission rate of each RB in a BS coverage can be calculated further；Specifically Ground, can obtain matrix A according to above-mentioned (2) formula:

Wherein, a in above-mentioned (3) formula_j+1,i=μ_j,i, j is the positive integer more than or equal to 1, a_1,iIt is Macrocell Corresponding to RB_iPeak transfer rate；Then can get the maximum overall transmission rate R of i-th RB_iFor:

$r_i=a_{1i}+\underset{m=2}{\overset{M+1}{\mathrm{\Σ}}}{a}_{\mathrm{mi}}---\left(4\right)$

Wherein, a in above-mentioned (4) formula_miFor being numbered the Femtocell of (m-1) at RB_iOn maximum transmitted Speed, m=2,3 ..., M+1, each RB can be obtained by above-mentioned (3) formula and (4) formula Maximum overall transmission rate, such as can record the maximum overall transmission rate of each RB by vector R, It is:

R=(r₁,r₂,…r_N) (5)

Determine module 13, the maximum overall transmission rate of each RB for calculating according to computing module 12, Determining interference result, this interference result includes part RB using maximum overall transmission rate the highest Carry out resource multiplex.

In the present embodiment, this interference processing means cover half block 13 really can be according in above-mentioned (5) formula The maximum overall transmission rate of each RB of record, determines the result carrying out interference process, thus passes through Part RB determined in this result carries out resource multiplex, and the maximum overall transmission rate of this part RB is greater than Other does not carries out the maximum overall transmission rate of RB of resource multiplex, is ensured to carrying out multiplexing RB's UE provides higher received signal quality.The present embodiment carry out disturb result execution during, In view of all UE in a BS coverage, either access the UE of a BS, still connect The UE of the 2nd BS disposed in entering its coverage, is i.e. being constituted with a BS and multiple 2nd BS The two-tier network system that coexists of Macrocell-Femtocell in, every by obtain in this network system Those UE are carried out interference process by individual UE measurement result on each RB；Compared to passing through ICIC When carrying out interference process, only consider that the resource distribution of the edge UE of adjacent macro base station has obvious advantage, One, it is contemplated that the interference problem of all UE in a BS coverage, the overall situation considers the situation of interference, Thus be applicable to heterogeneous network is carried out interference process；Its two, give as a example by the heterogeneous network shown in Fig. 3 With explanation, each 2nd BS can be affected by multiple 2nd BS of surrounding, if being carried out by ICIC Interference processes, and can produce bigger signaling consumption, and resource utilization can be caused relatively low.

In the present embodiment, carry out being determined by chance algorithm of part RB of resource multiplex, And an each 2nd BS or UE is when obtaining himself peak transfer rate on each RB, It is also based on what chance algorithm performed.Although it is corresponding that existing multicast system has used chance algorithm to perform Function, such as, in multicast system, in order to meet being properly received of worst user, the speed of multicast It is exactly the receiving velocity of worst user, in order to improve the receiving velocity of single, by user's receiving velocity Sequence, is first transmitted based on part optimal user in all users of chance algorithm picks, i.e. by repeatedly After multicast, can being properly received with the whole user of basic guarantee, simultaneously every time the speed of multicast has the biggest Promote.Various embodiments of the present invention are then to be applied in unicast system by this chance algorithm, it should be noted that The feature of multicast system is broadcast characteristic, i.e. BS sends same content to multiple UE every time, sends out every time The power sent is identical, and the mode of transmission is relatively simple, it is easy to accomplish；If should be in clean culture by chance algorithm In system, owing to BS is usually different to the content that each UE sends, the mode that therefore sends is also with many Difference in broadcast system, various embodiments of the present invention should chance algorithm be by specifically changing the mode of transmission Enter, with mate unicast system should scene, thus all UE dry in realizing a BS coverage Disturb process, to provide the interference coordination mode being adapted to whole network system.

The interference processing means that the present embodiment provides, is arranged in a BS, the covering model of a BS Deploying multiple 2nd BS in enclosing, this interference processing means receives a BS by receiver module and covers model Enclose interior each 2nd BS peak transfer rate on each RB, and receive access the oneth BS's The peak transfer rate that each UE records on each RB, thus calculated each by computing module The maximum overall transmission rate of RB, and then determine dry according to the maximum overall transmission rate of each RB calculated Disturb the result of process, i.e. achieved by chance algorithm and part RB in network system is carried out resource again With, the interference processing means that the present embodiment provides, when performing interference and processing, is counted by chance algorithm Need the measurement result obtaining each UE in a BS coverage on each RB during calculation, i.e. exist Perform the interference problem in view of all UE in BS coverage when interference processes, thus solve In prior art of having determined by the way of ICIC carries out interference control, it is impossible to solve user in heterogeneous network Interference problem.

Further, the present embodiment carries out interference process compared to by ICIC, the most relatively low BS Between signaling consumption, improve resource utilization simultaneously；It addition, the present embodiment is by chance algorithm Obtain each 2nd BS or UE peak transfer rate on each RB, due to each reality of the present invention Execute that the network scenarios of example is in unicast system should, therefore, apply chance algorithm in multicast system Mode different, the mode of thinking of chance algorithm is specifically applied in unicast system by the present embodiment, to carry For a kind of interference processing means being applicable to heterogeneous network.

Alternatively, the structural representation of the another kind of interference processing means that Fig. 5 is provided by the embodiment of the present invention Figure, on the basis of above-mentioned embodiment illustrated in fig. 4, the interference that the present embodiment shown in Fig. 5 provides processes dress In putting, determine that module 13 may include that quantity determines unit 14, for according to a BS belonging network (Signal to Noise Ratio is referred to as: SNR), true based on chance algorithm the current signal of system The quantity of the RB of fixed pending resource multiplex is n, and wherein, n≤N, N are the sum of RB；Knot Fruit determines unit 15, for the maximum overall transmission rate of each RB calculated according to computing module 12 and Quantity determines the quantity of the RB of the fixed pending resource multiplex of unit 14, determines interference result, Interference result specifically includes and uses n the RB that maximum overall transmission rate is the highest to carry out resource multiplex.

The present embodiment, in implementing, can record each RB to vector R in above-mentioned (5) formula R is ranked up by big overall transmission rate according to descending, and by the result record of sequence in vector R', tool Body is: R'=(r₁',r₂',…r_N'), wherein, r₁'≥r₂'≥…≥r_N', meanwhile, vector B record vector R' is each in definition Individual element label on each RB, it may be assumed that B=(b₁,b₂,…,b_N), wherein, b_i∈ 1,2 ..., N}, thus This determines that module 13, according to SNR current in network system described in a BS, selects n RB to carry out Resource multiplex, and this n RB is specially b₁,b₂,…,b_n, corresponding speed is respectively r₁',r₂',…,r_n'。

In the present embodiment, determine that module 13, when determining interference result, is taking into full account first While current SNR in BS belonging network system, use chance algorithm to determine and carry out resource multiplex The quantity of RB, i.e. determine that module 13 has got maximum total transmission of each RB at computing module 12 On the basis of speed, obtain, by chance algorithm, n the RB that above-mentioned maximum overall transmission rate is the highest, thus Resource multiplex is carried out by this n the RB obtained；It is apparent that due to maximum total transmission of this n RB Speed is higher relative to for other RB, carries out can ensure that during resource multiplex the UE of this n RB of multiplexing There is preferable received signal quality, thus ensure the performance of network system.

Further, the interference processing means that the present embodiment provides also includes sending module 16, for often Individual 2nd BS sends and determines the interference result that module 13 is determined, interference result is used for indicating Each 2nd BS is by n the RB corresponding UE the highest with maximum overall transmission rate, to n RB Carry out resource multiplex.It should be noted that determine that the interference result that module 13 is determined can also be wrapped Include and use N-n the RB that maximum overall transmission rate is minimum to carry out orthogonal distribution, then interference result is also For indicating each 2nd BS to not carrying out the UE of resource multiplex, N-n RB is used to carry out orthogonal point Join.It can thus be seen that for the RB of fixed qty allocated in network system, pass through the present embodiment There is provided interference processing means, may finally determine the RB carrying out resource multiplex particular number and The UE of this n RB of multiplexing, and carry out the particular number of the RB of orthogonal distribution and corresponding to being somebody's turn to do The UE of N-n RB, the above results is to record on each RB based on UE each in this network system SINR, and obtained by the current SNR of network system, due to a BS and all 2nd BS The whole resource of multiplexing, the present embodiment provide device by collecting the result that each UE records, and based on Chance algorithm filters out the peak transfer rate of each RB, it is contemplated that the overall interference situation of network system, To disturbing little RB to carry out resource multiplex, carry out orthogonal distribution to disturbing strong RB, it is achieved moving of resource State multiplexing.Compared in prior art by the way of ICIC carries out interference process, can by chance algorithm With the dynamic ratio adjusting RB multiplexing, it is achieved the interference coordination of whole UE in network system.

In the present embodiment, the occupation mode of resource multiplex and orthogonal distribution is combined, can be cleverer The use resource of elasticity of living.For example, all of BS is to use whole RB at initial time, But by RB information, the analysis of disturbed condition, part RB is available for multiple UE and uses, and remains simultaneously RB then use the occupation mode of orthogonal distribution, thus the RB that multiplexing interference is little, orthogonal distribution interference is big RB；In actual use, in this way, the change of RB can preferably be followed the tracks of, it is judged that dry Situation about disturbing, thus Flexible use resource, to realize the matched well of resource and user.It addition, pass through The judgement of network side, analysis, it is provided that the allocative decision that RB uses.

Specifically, in network system described in a BS, the calculation of handling capacity is: receiver module 11, it is additionally operable to obtain in a BS coverage, carries out the resource that all UE of resource multiplex calculate The total speed of multiplexing, and the total speed of orthogonal distribution that all UE carrying out orthogonal distribution calculate；Accordingly Ground, computing module 12, be additionally operable to according to receiver module 11 obtain the total speed of resource multiplex and orthogonal point Join total speed, calculate the handling capacity of a BS network system.Same with shown in above-mentioned Fig. 4 and Fig. 5 It is explained as a example by the label that in embodiment, each computing formula is corresponding, above-mentioned n the RB carrying out resource multiplex Total speed C_oCan be:

$C_o=\underset{i=1}{\overset{n}{\mathrm{\Σ}}}{r_i}^{\′};$

Total speed C of above-mentioned N-n the RB carrying out orthogonal distribution_tCan be: C_t=B log₂(1+SNR), Wherein, SNR is the current SNR of a BS belonging network system, then can draw this network system Handling capacity is:

$\begin{array}{c}{R}_{\mathrm{total}}=C_o+C_{\mathrm{Orthogonal}}=\underset{i=1}{\overset{n}{\mathrm{\Σ}}}{r_i}^{\′}+\underset{t=N-n}{\overset{N}{\mathrm{\Σ}}}{C}_t\\ =\underset{j=1}{\overset{M}{\mathrm{\Σ}}}\underset{i=1}{\overset{n}{\mathrm{\Σ}}}{\mathrm{\μ}}_{j,i}+\underset{i=1}{\overset{n}{\mathrm{\Σ}}}{\mathrm{\μ}}_{\mathrm{macro},i}+\underset{t=N-n}{\overset{N}{\mathrm{\Σ}}}{C}_t\\ =\underset{j=1}{\overset{M}{\mathrm{\Σ}}}\underset{i=1}{\overset{n}{\mathrm{\Σ}}}B\·\log (1+{\mathrm{SINR}}_{j,i})+\underset{i=1}{\overset{n}{\mathrm{\Σ}}}B\·\log (1+{\mathrm{SINR}}_{\mathrm{macro},i})+\underset{t=N-n}{\overset{N}{\mathrm{\Σ}}}B\·\log (1+\mathrm{SNR})\end{array}---\left(6\right)$

The handling capacity of a BS belonging network system is calculated by above-mentioned (6) formula, can be clear and definite Embody this network system and there is higher handling capacity, it is achieved thereby that resource reasonable in this network system Utilize, and the handling up of the service rate of the total each UE of the system that can ensure that and whole network system Amount.

Chance algorithm is applied in the network system of small station dense distribution by the present embodiment, according to this network system Unite the interference variations of total each UE, can scheduling resource dynamically, realize resource multiplex with orthogonal point The combination joined is simultaneously, it is ensured that the total throughout of system, makes the most UE in system all obtain The highest transfer rate.Specifically, according to the selectivity characteristic of chance algorithm, it may be determined that with resource The optimal user joined, it is achieved resource and the matched well of user, it is ensured that system gain；And due to The change of RB, after chance algorithm several times, unicast system can also obtain the increasing of similar multicast system Most of UE in benefit, i.e. system can accept service with higher rate, thus has excavated in system The potential of resource, it is ensured that the service quality of user.Carried out at interference by ICIC with prior art The mode of reason compares, and the present embodiment is not which money of each community of simple instruction by chance algorithm Source can be used, thus avoids interference, but consider the handling capacity of system from entirety, considers the biography of user simultaneously Defeated speed, carries out unified dispatching distribution, hence for disturbing little RB to carry out multiplexing, and for dry Disturb strong RB and then use orthogonal distribution, thereby may be ensured that the overall performance of system.

The interference processing means that various embodiments of the present invention provide is applied particularly to the network system shown in above-mentioned Fig. 3 In system, due to the differing greatly of service rate in this system, therefore the business of different rates is used difference Mechanism, the use resource that on the one hand can more optimize, on the other hand can reduce the complexity of related algorithm Degree, it is thus achieved that preferably gain.On this basis, business can be classified, be high speed business and Low-rate traffic, Femtocell provides high speed business, and Macrocell both can provide high speed business, it is possible to Low-rate traffic is provided；Owing to high speed business has data volume greatly, to rate requirement high, therefore need Using preferable RB, various embodiments of the present invention specifically propose what chance algorithm combined with orthogonal distribution Resource allocation policy, reduces the interference between Macrocell and Femtocell.

Specifically, there is in Macrocell overlay area the existence of multiple high speed Femtocell, and entirely Portion shares RB, therefore can produce stronger interference between Femtocell with Macrocell, and, by Select special frequency channel in Macrocell at cell edge, and strengthen transmitting power, therefore at Femtocell In the interference of some RB may be bigger.In this case, various embodiments of the present invention use chance to calculate Method, in OFDMA system, Femtocell Yu Macrocell shares each RB, and each RB phase The most orthogonal, it is contemplated that the decline of each RB be change, so chance algorithm can flexibly make be System selects suitable RB to carry out resource multiplex for user.Further, since each user is on each RB Decline and interference are different, and therefore, chance algorithm is under pursuing the target that power system capacity is maximum, for Each RB selects optimum user, and the RB i.e. elected by chance algorithm, owing to being disturbed degree Little, it is available for Macrocell and multiple Femtocell and is shared, greatly improve the capacity of system, and For remaining RB, then the user of optimum according to disturbance regime, can be respectively allocated to.Said method Can according to the situation of RB, by chance algorithm select flexibly multiplexing by the way of orthogonal distribution, both Improve the availability of frequency spectrum, reduce again interference.By above-mentioned selection and distribution, can make all of RB maximizes the use, thus preferably promotes the capacity of system.

The chance algorithm that various embodiments of the present invention are proposed is it is emphasised that resource and the matching problem of user, heavy Point solves the interference problem between macrocellular and the small station wherein disposed.Soft-frequency reuse of the prior art It is the multiplexing mechanism of a kind of fixed frequency planning, and is mainly used in the interference solved between macrocellular, main To be distributed and to adjust transmitting power to realize by predetermined frequency, but, for small station dense distribution For scene, soft-frequency reuse mode can not solve interference problem.And chance algorithm is shared RB's Under premise, according to the change of disturbance regime, it is that each BS distributes RB dynamically, and determines use simultaneously The UE of RB, the interference i.e. solving resource in system by the way of a kind of dynamic allocation of resources exists dynamic The problem of state property.Various embodiments of the present invention by chance algorithm in implementing, each in system UE both participates in, i.e. by collecting the related data information of user side, it is thus achieved that each community is on each RB Disturbed condition, consider the handling capacity of whole system, so that it is determined that the scheduling mode of resource, and will Result informs each BS, determines the final method of salary distribution.

It is in different SNR's below by way of the interference processing means using the present embodiment to provide in network system Under the conditions of, the interference result being determined the chance algorithm under three kinds of frequency resource planning compares Relatively, these three kinds of frequency resources be planned to the most orthogonal (Orthogonal Allocation, referred to as: OA), chance algorithm (Opportunistic when partial orthogonality (partial reuse) and complete multiplexing Scheme, referred to as: OPS), Fig. 6 distributes with total by a kind of resource that the embodiment of the present invention is provided The graph of relation of speed, the another kind of resource that Fig. 7 is provided by the embodiment of the present invention is distributed and total speed Graph of relation, the pass of another resource distribution that Fig. 8 is provided by the embodiment of the present invention and total speed Being curve chart, in above-mentioned Fig. 6 to Fig. 8, vertical coordinate represents all in the network system belonging to a BS Total speed of RB, the interference processing means that Fig. 6 to Fig. 8 provides for the present embodiment is in not in network system The graph of relation obtained during with SNR, the SNR in Fig. 6 is 2dB, and the SNR in Fig. 7 is 18dB, SNR in Fig. 8 is 28dB；Complete orthogonal time, between Macrocell and Femtocell, and All use orthogonal resource between Femtocell, the most there is not co-channel interference, it is contemplated that Macrocell The scope covered is relatively big, therefore can distribute more resource to Macrocell, and each Femtocell divides The number of resources obtained is identical, but this mode makes the spendable resource in all of community little, the most whole The capacity of system is less, and total speed of RB is the curve OA in fixed value, i.e. figure and abscissa Unrelated；When partial orthogonality, between Macrocell and Femtocell, all of RB is divided For two parts, a part individually takies for Macrocell, and another part is that all of Femtocell is multiple With, use chance algorithm to be allocated, the abscissa in figure represents the hundred of the resource that Macrocell takies Proportion by subtraction；When complete multiplexing, the RB that Macrocell with Femtocell multiplexing is whole, the abscissa in figure Representing the percentage ratio being accounted for total RB by n RB of chance algorithm picks, remaining RB uses orthogonal point Join.

By above-mentioned Fig. 6 to Fig. 8 it can be seen that along with the lifting of SNR, under three kinds of frequency resources planning Total speed has lifting, and under basic, normal, high signal to noise ratio, performance when partial orthogonality and complete multiplexing is wanted Be better than complete orthogonal time performance, the method for partial orthogonality and complete multiplexing that main reason is that is all necessarily The system that increases in degree can be with the number of RB, and the most same RB is available for multiple user and uses, and is therefore The overall performance of system is more excellent.Specifically, at low signal-to-noise ratio, in the case of complete multiplexing, along with multiplexing The raising of RB ratio, the total speed of system is the biggest, this is because this multiplexing RB can make for multiple users With, the number of users that can service is the most, and overall performance is the best, and in the case of partial orthogonality, When the RB that Macrocell takies is the most, the overall spendable RB of Femtocell tails off, therefore multiplexing The number of RB tails off, and the total speed of system also can decline therewith；In middle signal to noise ratio, the situation of complete multiplexing Under, the maximum of the total speed of system do not occur in multiplexing RB be 100% take in the case of, but Between 60%-70%, this is that noise is less, and multiplexing RB is provided to many owing to now SNR is relatively big Individual user uses, and the performance of system will be had a certain impact, therefore by the co-channel interference between such user Peak value do not appear in 100% take in the case of, and in the case of partial orthogonality, due to the property of multiplexing RB Can be affected by co-channel interference, and the resource orthogonality of Macrocell with Femtocell can be kept away Exempt from interference, thus while the percentage ratio that Macrocell takies resource is changing, but the change of the performance of system Not quite, and completely orthogonal under the conditions of, the total speed of system increases with the lifting of SNR；In high noise Ratio, in the case of complete multiplexing, the total speed of system gradually reduces, this is because the shadow of now noise Ring the least, and the co-channel interference produced by multiplexing RB will occupy leading position, therefore along with multiplexing RB The increase of ratio, co-channel interference also will increase, and therefore overall performance can decline, in the situation of partial orthogonality Under, the RB ratio taken along with Macrocell increases, and overall Femtocell can be by the quantity of RB Reduce, i.e. the quantity of multiplexing RB reduces, and therefore co-channel interference is less, thus the total speed of system rises, In the case of completely orthogonal, completely eliminating co-channel interference, therefore the performance of system is compared and is improved before A lot.It addition, the height of the no matter SNR that system is current, completely orthogonal in the case of, due to The RB that Macrocell and each Femtocell takies determines that, the most there is not ratio problems, therefore Relation curve OA is a straight line being not changed in.

Further, a kind of SNR that Fig. 9 is provided by the embodiment of the present invention and the relation curve of total speed Figure, shows the change along with SNR in Fig. 9, the lower total speed of system of above-mentioned three kinds of frequency resources planning Change curve, be can be seen that by the tendency of three curves in Fig. 9, along with the increase of SNR, system is the fastest Rate is to increase, but, use the systematic function of multiplexing RB to be better than the system using orthogonal distribution RB Performance, when this is owing to determining multiplexing RB by chance algorithm, in the case of considering interference, maximum Change total speed of each RB, thus improve the performance of system, and in conditions different for SNR Under, the ratio of the multiplexing RB determined by chance algorithm is also different.
