In order to better illustrate technical scheme, a model of place is created first, and the model of place simulates super density network.Set up one and constitute base station system more than one by B radius for R hexagon base station, in this system, research object is only used as using downlink.Base station is located at the cluster center of each base station, and equipped with N_tRoot antenna, user antenna number is（N_rl ).Its local user is dispatched on different running time-frequency resources by base station according to specific scheduling strategy, and each base station at most only services a user on each running time-frequency resource.

Each embodiment of the invention is described in further detail with reference to Figure of description, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.

Embodiment one：

It is a kind of schematic flow sheet for cooperation between base stations method that the embodiment of the present invention one is provided as shown in Fig. 1.Methods described can be as described below.

Step 101:Source base station receives the resource scheduling information and interference information that adjacent base station is sent.

In step 101, each base station（Adjacent base station including source base station and source base station）For local subscriber apparatus（UE, User Equipment) distribution running time-frequency resource when, it is thus necessary to determine that whether each running time-frequency resource is taken by other UE, if the running time-frequency resource is taken by other UE, also needs to determine to be allocated The interference information of adjacent base station suffered by other UE of running time-frequency resource.

Wherein, the interference information is typically represented by interference strength.For example：Interference value： -87dBm;Or represented by channel strength.For example：Channel strength is numbered：- 85-90 numberings are 4, are not limited here.

Specifically, source base station receives the resource scheduling information that adjacent base station is sent, wherein, the radio spectrum resources distributed and used by the adjacent base station are contained in the resource scheduling information.

For example：The adjacent base station of source base station contains adjacent base station 1, adjacent base station 2 and adjacent base station 3, and now adjacent base station 1 is that user equipment 1 is assigned with running time-frequency resource 1;Adjacent base station 2 is that user equipment 2 is assigned with running time-frequency resource 2;Adjacent base station 3 is that user equipment 3 is assigned with running time-frequency resource 3;So the resource scheduling information that running time-frequency resource 1 is used is sent to source base station by adjacent base station 1；The resource scheduling information that running time-frequency resource 2 is used is sent to source base station by adjacent base station 2；The resource scheduling information that running time-frequency resource 3 is used is sent to source base station by adjacent base station 3.

In order to lift message transmission rate, cooperation between base stations mode is proposed, but will so cause data transmission quality to decline, therefore, source base station also needs to receive the interference information that adjacent base station is sent, it is necessary to prevent from interfering in cooperation between base stations.

Wherein, the interference strength of the interference base station of user equipment and the interference base station in the adjacent base station is contained in the interference information.

For example：Still illustrated by taking above-mentioned example as an example.Interference base station that the user equipment 1 in adjacent base station 1 is subject to and the interference strength of the interference base station are contained in the interference information.

User equipment judges whether the interference by other base stations and the mode including but not limited in the following manner of determination interference strength in adjacent base station：

User equipment in adjacent base station is measured to the channel strength of other base stations, and the channel strength obtained according to measurement judges whether other base stations are the interference base stations of itself, and when it is determined that being interference base station, further determines whether to belong to strong jamming base station.

It should be noted that the channel strength measurement being related in the embodiment of the present invention has generally comprised measuring reference signals receiving power/reference signal receiving intensity（ Reference Signal Receiving Power/Reference Signal Receiving Power, R.SRP/RSRQ：), as using RSRP be main Basis for estimation, is not specifically limited here.

Specifically, judge other base stations whether be the strong jamming base station of itself mode comprise at least it is following two：

First way：

User equipment will measure wealthy value of the obtained RSRP/RSRQ values with setting and be compared, and be obtained when measurement：When SRP/RSRQ values are more than the threshold value of setting, determine that other base stations belong to strong the thousand of user equipment still base stations.

The second way：

The RSRP/RSRQ values that measurement is obtained are reported serving BS by user equipment, the RSRP/RSRQ values received and the threshold value of setting are compared by serving BS, when the RSRP/RSRQ values received are more than the threshold value of setting, determine that other base stations belong to strong the thousand of user equipment and disturb base station.

Wherein, the wealthy value of setting can be determined according to experimental data, can also according to actual needs be determined, not limited here.

Because the interference strength produced by strong jamming base station will influence data transmission quality, accordingly, it would be desirable to determine to cause user equipment strongly disturbing base station emphatically.

Step 102:The source base station is according to the resource scheduling information and the interference information, it is determined that the cooperation between base stations strategy with the adjacent base station.

In step 102, the source base station selects a radio spectrum resources to be allocated from the radio spectrum resources of configuration.

The source base station judges whether the radio spectrum resources to be allocated are used by adjacent base station distribution according to the resource scheduling information.

Because source base station by the radio spectrum resources to be allocated of selection before user equipment is distributed to, need, according to the resource scheduling information for receiving adjacent base station transmission, to determine whether the radio spectrum resources to be allocated are distributed to other users equipment by the adjacent base station and used.

If the radio spectrum resources to be allocated are not yet used by adjacent base station distribution, the source base station determines to perform joint data transfer in the radio spectrum resources to be allocated with the adjacent base station；If the radio spectrum resources to be allocated are used by adjacent base station distribution, the source base station The cooperation between base stations strategy with the adjacent base station is further determined according to the interference information.

As can be seen here, source base station is according to the resource scheduling information and the interference information, it is determined that can substantially be divided into two classes with the cooperation between base stations strategy of the adjacent base station：

First kind coordination strategy is：Radio spectrum resources to be allocated not yet distribute what is used by the adjacent base station, it is determined that performing the coordination strategy of joint data transfer in the radio spectrum resources to be allocated with the adjacent base station.

Equations of The Second Kind coordination strategy is：Radio spectrum resources to be allocated not yet distribute what is used by the adjacent base station, and the source base station determines the cooperation between base stations strategy with the adjacent base station according to the interference information.

Step 103:The source base station performs cooperation between base stations operation according to the cooperation between base stations strategy with the adjacent base station.

In step 103, if the cooperation between base stations strategy that source base station is determined belongs to the first kind coordination strategy mentioned in step 102, source base station determines to perform joint data transfer in the radio spectrum resources to be allocated with the adjacent base station.

Specifically, the source base station receives the measurement report that the first user equipment is sent（That is Measure Report).

Wherein, the Reference Signal Received Power between the source base station/reference signal receiving intensity of the first user equipment measurement, and the Reference Signal Received Power between the adjacent base station/reference signal receiving intensity that first user equipment is measured are contained in the measurement report.
