Embodiment

Ground is without loss of generality, following examples among the present invention all are to be applied in LTE network or the LTE-A network, macro base station is such as but not limited to Node B (Node B) or evolution type Node B (eNB), and the attached access point of macro base station jurisdiction is such as but not limited to femto base station (pico BS), base station from home (femto BS) or relay station (relay station).Those skilled in the art will be understood that core of the present invention and essence also can be applied to other mobile communications networks.

Fig. 1 shows the schematic diagram of the cell configuration of mobile communications network according to an embodiment of the invention.Circular mark represents macro base station among the figure, and triangular marker represents the access point of lower-wattage.There is shown seven adjacent macro base stations and cell configuration thereof, particularly particularly three macrocells 102,103,104 that show macro base station 101 and serve, and be positioned within the signal coverage of macro base station 101 and by the attached access point 121,122,123,124,125 of macro base station 101 jurisdictions (scheduling resource distribution).Certainly, such cell configuration only is exemplary and nonrestrictive.Although macro base station 101 is served three sector 102-104, what those skilled in the art will be understood that is, the downlink radio frequency resource of the attached access point within macrocell and the signal coverage thereof is normally done as a wholely to be dispatched together by macro base station; And between each macrocell that same macro base station is served, then allow the multiplexing of frequency spectrum resource because of separating of sense.

Fig. 2 shows the schematic diagram of the network configuration within the macrocell of macro base station according to an embodiment of the invention and service thereof.There is shown a macrocell 211 of macro base station 201 and service thereof, be positioned at two the attached access points 221 and 222 within the signal coverage of macrocell 211, subscriber equipment 251-253 within the service area of access point 221, the subscriber equipment 254-256 within the service area of access point 222.Intuitively, subscriber equipment 251,252,254 is positioned at the edge of access point service area separately and near macro base station 201, thereby is easier to be subject to the interference from the signal of macro base station 201.Can avoid interference in gap frame (ABS) by the downlink data dispatching with this type of subscriber equipment.

Fig. 3 shows the flow chart of the communication means in the isomery mobile communications network according to an embodiment of the invention, and described isomery communication network comprises macrocell and a macro base station thereof and is positioned within this macrocell at least one attached access point by this macro base station jurisdiction.The method comprises step 301,302,303 that macro base station one side carries out, 304 and the step 321,322,323,324 carried out in attached access point one side.Below in conjunction with Fig. 2, Fig. 3 the method is illustrated.

At first in attached access point 221,222 1 side execution in step 321, each attached access point is determined the risk of interferences subscriber equipment based on received signal quality respectively at least from the subscriber equipment of separately service.The downlink data of risk of interferences subscriber equipment need to be dispatched to gap frame (ABS) to avoid the interference between the residential quarter.

In a kind of concrete execution mode, in step 321, attached access point 221,222 subscriber equipmenies that will serve separately, that Reference Signal Received Quality (RSRQ) is lower than predetermined threshold are defined as the risk of interferences subscriber equipment.The predetermined threshold here is such as but not limited to-6dB.The reference signal here refers to the specific reference signals of attached access point, and this implementation is applicable to the situation that attached access point (especially relay station) also has the cell specific reference signal of self.

In the concrete implementation of another kind, in step 321, the subscriber equipment that the difference of attached access point 221, the 222 access point signals qualities of reception that will serve separately, attached and macro base station signal receiving quality is lower than predetermined threshold is defined as the risk of interferences subscriber equipment.This implementation has been considered the signal receiving quality from macro base station and attached access point simultaneously to the risk of interferences subscriber equipment determine more accurate.

Communication between macro base station 201 and the attached access point 221,222 thereof is preferably finished by X2 interface.

Next in attached access point 221,222 1 side execution in step 3 22, send signaling messages with the classified information of the subscriber equipment of indicating each attached access node and being served by X2 interface to macro base station 201.Classified information is for the sum, the quantity of risk of interferences subscriber equipment wherein and the quantity of non-risk of interferences subscriber equipment that represent the subscriber equipment that an access point is served.Because sum is the quantity of risk of interferences subscriber equipment and the quantity sum of non-risk of interferences subscriber equipment, in signaling message, can only indicate among the three both, the for example sum of access point subscriber equipment of serving and the quantity of risk of interferences subscriber equipment wherein are to reduce signaling consumption.

In a kind of specific implementation, the classified information in this signaling message comprises two designators, is respectively applied to indicate subscriber equipment sum that the attached access point that sends this signaling message serves and the concrete numerical value of risk of interferences subscriber equipment quantity wherein.When the service ability of this attached access point was no more than 64 subscriber equipmenies, the designator of two 6 bits can be satisfied the demand.

In another kind of specific implementation, the designator that classified information comprises is used to indicate the quantity rank.Such as but not limited to, per 8 subscriber equipmenies are a rank, 0-7 subscriber equipment of 0 expression, and 8-15 subscriber equipment of 1 expression, 16-23 subscriber equipment of 2 expressions, by that analogy.Although such mode feedback accuracy is lower, can further reduce signaling consumption.And macro base station determines the gap frame take complete subframe as unit, and such feedback accuracy also can satisfy user demand.

In macro base station 201 1 sides, in step 301, receive the signaling message from the classified information that is used to indicate the subscriber equipment that described attached access point serves of attached access point (221,222).As previously mentioned, this signaling message receives by X2 interface.

As previously mentioned, classified information is for the sum, the quantity of risk of interferences subscriber equipment wherein and the quantity of non-risk of interferences subscriber equipment that represent the subscriber equipment that an access point is served.Because sum is the quantity of risk of interferences subscriber equipment and the quantity sum of non-risk of interferences subscriber equipment, can only indicate among the three both in signaling message, for example classified information comprises the quantity of the total quantity of the subscriber equipment that each access point is served respectively and risk of interferences subscriber equipment wherein.

According to this classified information, macro base station 201 can be learnt the quantity of the sum of the subscriber equipment that each access point is served respectively, risk of interferences subscriber equipment wherein and the quantity of non-risk of interferences subscriber equipment.These subscriber equipment quantity that macro base station 201 is learnt can be concrete numerical value, also can be an order of magnitude not (or scopes).

Next, in step 302, macro base station 201 is determined the density of gap frame based on proportional fairness principle.

Particularly, the density of the gap frame quantity that is confirmed as the risk of interferences subscriber equipment that each attached access point 221,222 serves is with respect to the ratio of the total quantity of macro base station 201 and described each attached access point 221,222 subscriber equipmenies of serving.

Below provide the derivation based on preferred gap frame (ABS) density of equitable proportion, derive and adopt such as defined symbol in the following table 1:

Table 1 symbol definition

For all subscriber equipmenies to a website carry out optimization based on equitable proportion, definition is such as the equitable proportion utility function of formula (1).

$U=\underset{m_j}{\mathrm{\Π}}\left(\stackrel{\‾}{r_j}\right)---\left(1\right)$

For the setting that does not have the gap frame (gap frame density is 0), utility function can be expressed as formula (2):

$U_0=\underset{m_j\∈\mathrm{eNB}}{\mathrm{\Π}}\left(\frac{r_j}{k_{\mathrm{eNB}}}\right)\·\underset{i}{\mathrm{\Π}}\left(\underset{m_j\∈\mathrm{Pic}{o}_i}{\mathrm{\Π}}\left(\frac{r_j}{k_i}\right)\right)---\left(2\right)$

For the gap frame (gap frame density is θ) is set, utility function can be expressed as formula (3):

$U_{\mathrm{\θ}}=\underset{m_j\∈\mathrm{eNB}}{\mathrm{\Π}}((1-\mathrm{\θ})\·\frac{r_j}{k_{\mathrm{eNB}}})\·\underset{i}{\mathrm{\Π}}\left(\underset{m_j\∈{\mathrm{Pico}}_i}{\mathrm{\Π}}(\underset{m_j\∈\mathrm{Victim}}{\mathrm{\Π}}(\mathrm{\θ}\·\frac{{r_j}^{\′}}{{k_i}^{\′}})\·\underset{m_j\∈\mathrm{Non}-\mathrm{Victim}}{\mathrm{\Π}}((1-\mathrm{\θ})\·\frac{r_j}{k_i-{k_i}^{\′}}))\right)---\left(3\right)$

So adopt formula (4) to calculate increment I _θ, it is effectiveness U _θWith U ₀Ratio:

$I_{\mathrm{\θ}}=\frac{U_{\mathrm{\θ}}}{U_0}=\frac{{(1-\mathrm{\θ})}^{k_{\mathrm{eNB}}+\underset{i}{\mathrm{\Σ}}(k_i-{k_i}^{\′})}\·{\mathrm{\θ}}^{\underset{i}{\mathrm{\Σ}}{k_i}^{\′}}\·\underset{i}{\mathrm{\Π}}{k_i}^{k_i}\·\underset{m_j\∈\mathrm{Victim}}{\mathrm{\Π}}\frac{{r_j}^{\′}}{r_i}}{\underset{i}{\mathrm{\Π}}{\left({k_i}^{\′}\right)}^{{k_i}^{\′}}\·\underset{i}{\mathrm{\Π}}{(k_i-{k_i}^{\′})}^{(k_i-{k_i}^{\′})}}---\left(4\right)$

Because there is following lemma: $\underset{i=1..k}{\mathrm{\Π}}\left({x_i}^{n_i}\right)\≤{\left(\frac{\underset{i=1..k}{\mathrm{\Σ}}{x}_i}{\underset{i=1..k}{\mathrm{\Σ}}{n}_i}\right)}^{\underset{i=1..k}{\mathrm{\Σ}}{n}_i}\·\underset{i=1..k}{\mathrm{\Π}}{n_i}^{n_i},$ Wherein, x _i〉=0, n _i∈ N, the condition that obtains equal sign is: $\∀i,j=1..k,\frac{x_i}{n_i}=\frac{x_j}{n_j}.$

So can obtain formula (5):

$I_{\mathrm{\θ}}=\frac{\underset{i}{\mathrm{\Π}}{k_i}^{k_i}\·\underset{m_j\∈\mathrm{Victim}}{\mathrm{\Π}}\frac{{r_j}^{\′}}{r_i}}{\underset{i}{\mathrm{\Π}}{{\mathrm{}}^{\left({k_i}^{\′}\right)}}^{{k_i}^{\′}}\·\underset{i}{\mathrm{\Π}}{(k_i-{k_i}^{\′})}^{(k_i-{k_i}^{\′})}}\·{(1-\mathrm{\θ})}^{k_{\mathrm{eNB}}+\underset{i}{\mathrm{\Σ}}(k_i-{k_i}^{\′})}\·{\mathrm{\θ}}^{\underset{i}{\mathrm{\Σ}}{k_i}^{\′}}$

$=A\·{(1-\mathrm{\θ})}^B\·{\mathrm{\θ}}^C$

$\≤A\·{\left(\frac{1}{B+B}\right)}^{B+C}\·B^B\·C^C---\left(5\right)$

$A=\frac{\underset{i}{\mathrm{\Π}}{k_i}^{k_i}\·\underset{m_j\∈\mathrm{Victim}}{\mathrm{\Π}}\frac{{r_j}^{\′}}{r_i}}{\underset{i}{\mathrm{\Π}}{\left({k_i}^{\′}\right)}^{{k_i}^{\′}}\·\underset{i}{\mathrm{\Π}}{(k_i-{k_i}^{\′})}^{(k_i-{k_i}^{\′})}}$

$B=k_{\mathrm{eNB}}+\underset{i}{\mathrm{\Σ}}(k_i-{k_i}^{\′})$

Wherein: $C=\underset{i}{\mathrm{\Σ}}{k_i}^{\′}.$

The condition that obtains equal sign is: $\frac{1-\mathrm{\θ}}{B}=\frac{\mathrm{\θ}}{C}.$

Namely work as

The time, can obtain maximized U _θWherein, k _ENBThe quantity that represents the subscriber equipment that this macro base station is served, k _iThe sum that represents the subscriber equipment that attached access point i serves, and k _iThe quantity of ' expression risk of interferences subscriber equipment wherein.

In following step 303, macro base station 201 carries out gap frame pattern based on the density of determined gap frame and selects.

Particularly, macro base station 201 is according to the product of the subframe of dispatching cycle sum with the density of determined gap frame, based on round the quantity that principle is determined the gap frame.For example, 10 subframes are a dispatching cycle, and determined gap frame density is 0.23 in the step 302, then should dispatching cycle the quantity of hollow subframe will be defined as 3.In the present invention, can come to carry out gap frame (ABS) pattern according to determined gap number of frames based on any favourable principle selects.For example, be easy meter, can with should be in dispatching cycle front 3 can be used for the gap frame subframe be defined as the gap frame.Round up and to ensure the downlink data that enough gap frames are used for scheduling risk of interferences subscriber equipment.

Then, in step 304, macro base station 201 selects to inform attached access point 221,222 by X2 interface with described gap frame pattern.

Particularly, macro base station 201 can send a binary sequence and indicate gap frame pattern to select, the length of this binary sequence equals the total quantity of subframe in the dispatching cycle, each binary number in the sequence is in order corresponding to each subframe in the dispatching cycle, and 1 expression gap frame, 0 represents the non-NULL subframe.

Following step is got back to attached access point 221,222 1 sides.

In step 323, attached access point 221,222 signaling messages that receive from the indication gap frame pattern of macro base station 201.As previously mentioned, this signaling message receives by X2 interface.

In step 324, attached access point 221,222 is informed the subscriber equipment that it is served with described gap frame pattern, and will be in step 321 downlink data dispatching of determined risk of interferences subscriber equipment in the gap frame.Particularly, attached access point 221,222 can be informed the subscriber equipment that it is served with gap frame pattern by radio resource control layer (RRC) signaling.

By using said method, the load balance between the subscriber equipment that can serve based on macro base station and attached access point thereof and be adaptively the gap frame density of macro base station calculation optimization, and correspondingly adjust gap frame pattern.The gap frame pattern of each macro base station configures thereby can upgrade independently.Therefore effective so that the configuration of system resource is more flexible.And, between macro base station and attached access point thereof, only need by a small amount of signaling consumption of X2 interface consumption.
