Description

Dispatching method, device and base station

Technical field

The present invention relates to communication technical field, particularly relate to a kind of dispatching method, device and base station.

Background technology

LTE(Long Term Evaluation, Long Term Evolution) the current multiple technologies that exist of system are for promoting up performance: for example go up line frequency choosing, up ICIC(Inter cell Interference collaboration, Inter-Cell Interference Coordination technology) etc., the adaptive technique that comprises some link layers: MRC/IRC(Maximum Ratio Combining/Interference Rejection Combining, merge/interference of high specific inhibition merging) self adaptation and advanced receivers etc.But this class technology Jun Shidan community independent process, do not take into full account scope more greatly, the demand processed of wider multi-cell coordination.The scene of the current 8R of China Mobile of take is example, by whole net IOT(Interference Over Thermal noise, disturbs the heat ratio of making an uproar) distribution analyze, 67% interference comes from adjacent cell, in station, the IOT of adjacent cell has accounted for principal element.

In omni-base station, the edge customer that is usually located at cell edge is strong to the interference of adjacent cell, and the central user that is positioned at center of housing estate to the interference of adjacent cell a little less than.Between traditional inhibition adjacent cell, the mode of uplink interference under mainly adopting is as follows: by path loss difference, determine edge customer and the central user in community, be about to the large user of path loss and be defined as external strongly disturbing edge customer, the little user of path loss is defined as to the central user of external weak jamming, shown in Figure 1, You Sange community cell0 in figure, cell1 and cell2, in figure, longitudinally form is frequency domain, as we can see from the figure, cell0, in cell1 and cell2, the frequency band position of each community is divided into two parts, wherein: 1/3 for edge band (figure bend fill area), for dispatching the edge customer that is positioned at cell edge, 2/3 for center frequency-band (figure white portion), for dispatching the central user that is positioned at center of housing estate, and when scheduling, neighbor cell inward flange frequency band and center frequency-band overlaid, and, center frequency-band and edge band overlaid in neighbor cell, because edge customer is strong to the interference of adjacent cell, this makes the edge band in same time section different districts can all stagger or partly stagger, in different time period scheduling, dispatch respectively in different districts the strongly disturbing edge customer of adjacent cell, the interference that the edge customer of cell edge is subject to is reduced, promote the throughput of edge customer.

Between traditional inhibition adjacent cell, the mode of uplink interference is applicable to omni-base station, but and is not suitable for directional base station.This is due in directional base station, the edge customer that path loss is large is externally weak jamming, for example: main lobe edge customer, and the little central user of path loss may be externally strong jamming, for example: left and right secondary lobe edge customer, so still adopt the method for uplink interference between traditional inhibition adjacent cell in directional base station, will make externally for the external dispatch frequency range for strongly disturbing central user in the edge customer of weak jamming and adjacent cell is overlapping, and then the interference that the edge customer that makes external weak jamming is subject to increases, cause the throughput of the external edge customer for weak jamming in directional base station to reduce.

This dispatching method that the embodiment of the present invention provides can be applied to directional base station, at directional base station, comprises at least Liang Ge community, the first community and the second community, and the scheduling of terminal in the first community and the second community can be controlled in base station.In embodiments of the present invention, the Serving cell that the first community is first terminal, the second community is the neighbor cell of the first community.

S102: interference type corresponding to the Jiang Yu band of position, base station is defined as the interference type of first terminal.

The interference type of first terminal represents that first terminal is to the adjacent cell of Serving cell, i.e. the second community, the annoyance level causing.In embodiments of the present invention, alternatively, interference type can comprise strong jamming and weak jamming.

In omni-base station, being positioned at the interference that the terminal at edge, Serving cell causes the adjacent cell of Serving cell is strong jamming, being positioned at the interference that the terminal at center, Serving cell causes the adjacent cell of Serving cell is weak jamming, the interference type that is positioned at the terminal at edge, Serving cell is strong jamming, the interference type that is positioned at the terminal at center, Serving cell is weak jamming, so can directly utilize the path loss difference of terminal transmission signal to determine the interference type of terminal.

And in directional base station, owing to adopting directional antenna, be limited to the impact of directional antenna launching beam, cannot directly by path loss difference, determine the interference type of terminal.For example, be positioned at the terminal under directional base station signal tower, if calculated according to traditional path loss difference, interference type is weak jamming; Other terminal of Er Yutong community is compared, this part terminal is received the descending RSRP(Reference Signal Receiving Power of Serving cell, Reference Signal Received Power) intensity is large, the intensity of descending RSRP of adjacent cell of receiving Serving cell is also large, the interference that adjacent cell is caused is strong jamming, and the interference type that is in fact positioned at the terminal under directional base station signal tower is strong jamming.

But according to the launching beam characteristic of directional antenna in directional base station, terminal in directional base station community in diverse location region is determined the interference of adjacent cell, and in base station, can preserve in advance the corresponding relation of the band of position and interference type, as shown in chart 1, the band of position providing for the embodiment of the present invention and the mapping table of interference type.

In base station, on the first frequency band, dispatch after first terminal, the quantity of occupied radio bearer in the whole frequency bands in the first community and the second community can also be added up respectively in base station, in the first whole frequency bands in community, in the quantity of occupied radio bearer and whole frequency bands, the ratio of the total quantity of radio bearer is the band efficiency of the first community, and the ratio of the total quantity of the radio bearer in the second whole frequency bands in community in occupied radio bearer quantity and whole frequency bands is the band efficiency of the second community.

S502: base station judges whether the band efficiency of the first community and the second community is all less than preset value.When being all less than preset value, carry out S503, otherwise, finish.Band efficiency is less than preset value, represents to have idle frequency band in community, and alternatively, in embodiments of the present invention, preset value can be 30%.

S503: base station judges whether the first frequency band and the second frequency band partly overlap.When the first frequency band and the second frequency band partly overlap, carry out S504, otherwise, finish.

In other embodiment of the present invention, alternatively, can also first carry out S503, then perform step S501, or step S501 and step S503 can carry out simultaneously.As long as the band efficiency of satisfied the first community and the second community is all less than preset value and the first frequency band and the second frequency band and partly overlaps, just can carry out 504.

S504: the 3rd frequency band is determined in base station in whole frequency bands of the first community.

The first frequency band and the second frequency band partly overlap, will cause the terminal that in first terminal and the second terminal, interference type is weak jamming, the type that is interfered is that the part of strong jamming terminal is disturbed, and the lap of the first frequency band and the second frequency band is larger, the annoyance level that the terminal that in first terminal and the second terminal, interference type is weak jamming is subject to is also larger.

So determine that the object of the 3rd frequency band is: in the situation that the first community and the second community exist idle frequency band, in the first community, find the frequency band that lap with the second frequency band is less than the lap of the first frequency band and the second frequency band and dispatch first terminal, take while realizing interference type when first terminal as weak jamming, reduce to be subject to the interference of the second community, or, when the interference type of first terminal is strong jamming, reduce the interference that the second community is caused.In embodiments of the present invention, the 3rd frequency band and the second frequency band zero lap, or the lap of the 3rd frequency band and the second frequency band is less than the lap of the first frequency band and the second frequency band.

Take Fig. 8 a and Fig. 8 b is below example, and the scheme that the embodiment of the present invention is provided describes.

In Fig. 8 a, left part is determined the 3rd frequency band frequency band schematic diagram before, in figure, cell01 is the first community, cell02 is the second community, the first frequency band and the second frequency band partly overlap, right side part is determined the frequency band schematic diagram after the 3rd frequency band, as we can see from the figure, and the 3rd frequency band and the second frequency band zero lap.In Fig. 8 b, left part is the position view of the first frequency band and the second frequency band, in figure, the first frequency band and the second frequency band partly overlap, right side is divided into base station and in the first community, determines the 3rd frequency band, as we can see from the figure, the lap of the 3rd frequency band and the second frequency band is less than the lap of the first frequency band and the second frequency band.

Alternatively, in the embodiment of the present invention, the concrete mode of determining the 3rd frequency band can be: take the center of whole frequency bands of the first community is symmetric points, frequency band with the first frequency band full symmetric is defined as to the 3rd frequency band, or, take first first area at frequency band place or the center of second area is symmetric points, and the frequency band with the first frequency band full symmetric is defined as to the 3rd frequency band.Certainly, in other embodiment of the present invention, only need to meet the 3rd frequency band and the second frequency band zero lap, or, the lap of the 3rd frequency band and the second frequency band is less than the requirement of the lap of the first frequency band and the second frequency band, can also adopt alternate manner to determine the 3rd frequency band.

S505: first terminal is dispatched in base station on the 3rd frequency band.

Alternatively, in embodiments of the present invention, as shown in Figure 7, the method can also comprise:

S506: the scheduling to first terminal on the first frequency band is finished in base station.

This step can be carried out after step S505, also can all be less than preset value and the first frequency band and the second frequency band at the band efficiency of judging the first community and the second community and carry out after partly overlapping.

The method that the embodiment of the present invention provides, when the first frequency band and the second frequency band partly overlap, can also be by the actual band efficiency of community in base stations detected, position to the frequency band of scheduling first terminal is adjusted, so that when the interference type of first terminal is weak jamming, reduce to be subject to the interference that in the second community, interference type is strongly disturbing terminal, or, when the interference type of first terminal is strong jamming, reduce the interference that the terminal that in the second community, interference type is weak jamming is caused.Therefore, the method can reduce and is arranged in directional base station and externally for the edge customer of weak jamming, is subject to the interference of adjacent area, and improving in directional base station is externally the throughput of the edge customer of weak jamming.

Alternatively, in embodiments of the present invention, in step S503, judgment result is that when the first frequency band and the second frequency band partly overlap, the method can also comprise:

The 4th frequency band is determined in base station in the second community, and the second terminal is dispatched in base station on the 4th frequency band.

In the embodiment shown in fig. 7, in the situation that the first community and the second community exist idle frequency band, in the first community, find the frequency band that lap with the second frequency band is less than the lap of the first frequency band and the second frequency band and dispatch first terminal.Alternatively, in embodiments of the present invention, can also in the second community, find the 4th frequency band, the 4th frequency band and the first frequency band zero lap, or the lap of the 4th frequency band and the first frequency band is less than the lap of the first frequency band and the second frequency band.Can realize equally when the interference type of first terminal is weak jamming, reduce to be subject to the interference of the second community, or, when the interference type of first terminal is strong jamming, reduce the interference that the second community is caused.

Alternatively, when the second terminal is dispatched in base station on the 4th frequency band, the method can also comprise: the scheduling to the second terminal on the second frequency band is finished in base station.

S506 is the same with step, end is the scheduling to the second terminal on the second frequency band, both can after base station starts to dispatch the second terminal on the 4th frequency band, carry out, and also can all be less than preset value and the first frequency band and the second frequency band at the band efficiency of judging the first community and the second community and just carry out after partly overlapping.

The method provided by the invention, when the first frequency band and the second frequency band partly overlap, can also, by the actual band efficiency of community in base stations detected, adjust dispatching the position of the frequency band of the second terminal.Therefore, the method can reduce equally and is arranged in directional base station and externally for the edge customer of weak jamming, is subject to the interference of adjacent area, and improving in directional base station is externally the throughput of the edge customer of weak jamming.
