Technical solution in order to better illustrate the present invention, creates a model of place first, and model of place simulation is super Density network.Establish one by B radius be R hexagon base station form base station system more than one, in this system, only with Downlink is as research object.Base station is located at the cluster center of each base station, and equipped with N_tRoot antenna, user antenna Number is (N_r-1).Its local user is dispatched on different running time-frequency resources by base station according to specific scheduling strategy, each base It stands and at most only services a user on each running time-frequency resource.

The each embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification, it is clear that described Embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field Those of ordinary skill's all other embodiment obtained without making creative work, belongs to protection of the present invention Range.

Embodiment one:

As shown in Figure 1, a kind of flow diagram of the cooperation between base stations method provided for the embodiment of the present invention one.The side Method 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 a 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 has been occupied by other UE, if the time-frequency Resource is occupied by other UE, then also it needs to be determined that being assigned the interference letter of adjacent base station suffered by other UE of running time-frequency resource Breath.

Wherein, the interference information is generally indicated by interference strength.Such as: interference value: -87dBm；Or pass through channel Intensity indicates.Such as: channel strength number: -85~-90 numbers are 4, here without limitation.

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

Such as: the adjacent base station of source base station contains adjacent base station 1, adjacent base station 2 and adjacent base station 3, and adjacent base station 1 sets at this time for user Standby 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；Adjacent base station 2 by when The resource scheduling information that frequency resource 2 is used is sent to source base station；The scheduling of resource that adjacent base station 3 is used running time-frequency resource 3 is believed Breath is sent to source base station.

In order to promote message transmission rate, proposes cooperation between base stations mode, but in cooperation between base stations, need to prevent phase Mutually interference, will cause data transmission quality to decline in this way, and therefore, source base station also needs to receive the interference information of adjacent base station transmission.

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

Such as: still it is illustrated by taking above-mentioned example as an example.The user equipment in adjacent base station 1 is contained in the interference information The interference strength of 1 interference base station being subject to and the interference base station.

In adjacent base station user equipment judge whether by other base stations interference and determine interference strength mode include But it is not limited to following manner:

User equipment in adjacent base station measures the channel strength of other base stations, and strong according to the channel that measurement obtains Degree judges whether other base stations are itself interference base stations, and when determination is interference base station, further determines whether to belong to Strong jamming base station.

It should be noted that channel strength measurement involved in the embodiment of the present invention has generally comprised measuring reference signals and has connect Receive power/reference signal receiving intensity (Reference Signal Receiving Power/Reference Signal Receiving Power, RSRP/RSRQ), generally it is not specifically limited here with RSRP for main judgment basis.

Specifically, judge other base stations whether be itself strong jamming base station mode include at least following two:

First way:

The RSRP/RSRQ value that measurement obtains is compared by user equipment with the threshold value of setting, as the RSRP/ that measurement obtains When RSRQ value is greater than the threshold value of setting, determine that other base stations belong to the strong jamming base station of user equipment.

The second way:

The obtained RSRP/RSRQ value of measurement is reported to serving BS by user equipment, will be received by serving BS RSRP/RSRQ value is compared with the threshold value of setting, and when the RSRP/RSRQ value received is greater than the threshold value of setting, determining should Other base stations belong to the strong jamming base station of user equipment.

Wherein, the threshold value of setting can be determined according to experimental data, can also not limited here determine according to actual needs It is fixed.

The interference strength as caused by strong jamming base station will will affect data transmission quality, and therefore, it is necessary to determine emphatically Strongly disturbing base station is caused to user equipment.

Step 102: the source base station is according to the resource scheduling information and the interference information, the determining and adjacent base station Cooperation between base stations strategy.

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

Whether the source base station judges the radio spectrum resources to be allocated by institute according to the resource scheduling information Adjacent base station distribution is stated to use.

Since source base station is before distributing to user equipment for the radio spectrum resources to be allocated of selection, basis is needed to connect Whether the resource scheduling information for receiving adjacent base station transmission determines the radio spectrum resources to be allocated by the adjacent base station point Dispensing other users equipment uses.

It can be seen that source base station is according to the resource scheduling information and the interference information, it is determining and the adjacent base station Cooperation between base stations strategy can be roughly divided into two types:

First kind coordination strategy is: radio spectrum resources to be allocated are not yet used by adjacent base station distribution, are determined The coordination strategy of joint data transmission is executed in the radio spectrum resources to be allocated with the adjacent base station.

Second class coordination strategy is: radio spectrum resources to be allocated are not yet used by adjacent base station distribution, described Source base station is according to the determining cooperation between base stations strategy with the adjacent base station of the interference information.

Step 103: the source base station executes cooperation between base stations behaviour according to the cooperation between base stations strategy, with the adjacent base station Make.

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

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