Embodiment
Low-power ABS has certain coverage, this is relevant with the transmitting power of ABS, Fig. 3 is the coverage schematic diagram of the low-power ABS shown in Fig. 2, as shown in Figure 3, for the UE A in RE region, because it is closer apart from macro base station, within being positioned at the coverage of the ABS3 that transmitting power is higher, therefore on ABS3, can be subject to the strong jamming of macro base station, and for UE B, because it is distant apart from macro base station, be positioned at outside the coverage of ABS3, the interference of the macro base station being therefore subject on ABS3 is acceptable.For the lower ABS2 of transmitting power, UE A and UE B are all positioned at outside its coverage, and the interference of the macro base station that therefore UE A and UE B are subject on ABS2 is all acceptable.For zero energy ABS1, its coverage is the equal of zero, and therefore UE A and UE B can not be subject to the interference of macro base station on zero energy ABS1.
As can be seen from the above analysis, for zero energy ABS1 and the lower ABS2 of transmitting power, all UE in RE region are operable, and for the higher ABS3 of transmitting power, out of use apart from the UE in the nearer RE region of macro base station, while carrying out descending scheduling in Microcell, should be as far as possible the UE apart from macro base station RE region far away be dispatched on ABS3 as UE B, and the UE apart from the nearer RE region of macro base station is dispatched on ABS1 and ABS2 as UE A, do not allow and seize more valuable zero energy ABS1 resource and the lower ABS2 resource of transmitting power apart from the UE in macro base station RE region far away, thereby ABS resource can be used more effectively.
Based on above-mentioned thought, the terminal scheduling scheme in a kind of heterogeneous network has been proposed in the present invention, can make ABS resource be effectively utilized, and then improve the utilance of ABS resource.
For make technical scheme of the present invention clearer, understand, referring to the accompanying drawing embodiment that develops simultaneously, scheme of the present invention is described in further detail.

Step 41: micro-base station receives the ABS configuration information that macro base station sends, comprising: the position of each ABS and transmitting power.
In actual applications, when ABS configuration information changes, when it renewal as macro base station, or, when the initial deployment of micro-base station is in heterogeneous network time, macro base station can by up-to-date ABS configuration information by and micro-base station between X2 interface send to micro-base station, in ABS configuration information, can comprise: the position of each ABS and transmitting power, position refers to it is which subframe, as 5 work song frames., need to strengthen existing X2 interface, for the transmitting power of indication ABS for this reason.
Step 42: micro-base station obtains respectively the distance between each UE and the macro base station in RE region.
In actual applications, micro-base station can be conventionally one of following two kinds of modes determine the distance between each UE and the macro base station in RE region.
1) mode one
In the manner, micro-base station obtains respectively the macrocell measurement result of the each UE in RE region, estimates the distance between each UE and the macro base station in RE region according to macrocell measurement result.
In general, each UE in RE region is the UE that is positioned at edge, Microcell, for Microcell, due within it is positioned at the coverage of macrocell, therefore the adjacent cell that signal is the strongest is all generally macrocell, like this, each UE in RE region conventionally can include macrocell measurement result in the measurement report that reports micro-base station, macrocell measurement result may be the Reference Signal Received Power (RSRP of macrocell, Reference Signal ReceivingPower) and/or Reference Signal Received Quality (RSRQ, Reference Signal Receiving Quality).RSRP and/or RSRQ that micro-base station can report according to the each UE in RE region estimate the distance between each UE and macro base station, and RSRP and/or RSRQ are larger, nearer apart from macro base station, otherwise far away.
2) mode two
In the manner, micro-base station can be by positioning the distance between each UE and the macro base station estimating in RE region to the each UE in RE region.
In LTE system, introduced the function that base station positions UE, micro-base station can be by positioning to estimate the distance between each UE and the macro base station in RE region to UE.

Wherein, nearest between UE 1 and macro base station, is thereafter UE 2, UE 3, UE 4 and UE 5 successively;
So, for lower-wattage ABS, the dispatching priority of 5 UE is followed successively by according to order from high to low: UE 1, UE 2, UE 3, UE 4 and UE 5;
For higher-wattage ABS, the dispatching priority of 5 UE is followed successively by according to order from high to low: UE 5, UE 4, UE 3, UE 2 and UE 1;
In the time that lower-wattage ABS is carried out to scheduling of resource, first dispatch UE1, be secondly UE2, be UE 3, UE 4 and UE 5 successively after in addition;
In the time that higher-wattage ABS is carried out to scheduling of resource, first dispatch UE5, be secondly UE4, be UE 3, UE 2 and UE 1 successively after in addition.
In addition, thought of the present invention also can be combined with existing other scheduling mode (as Proportional Fair).
Such as, for arbitrary ABS, micro-base station is determined after the dispatching priority of the each UE in RE region according to the mode beyond step 43, according to the distance between each UE and macro base station in RE region, the each UE being respectively in RE region distributes a weight coefficient, and is that each UE in RE region distributes new dispatching priority according to the dispatching priority of determining and the weight coefficient that distributes;
