Abstract

The invention provides a measuring and collocation method in an interference coordination mechanism. According to the principle that subframe sets of absolute blank subframes (ABS) adopted among Picos in mutual strong interference are not intersected, a macro Pico coordinates the subframe sets of the ABS for each Pico in the coverage area, then each Pico determines measuring subsets adopted by user equipment (UE) in each area to measure the Pico of adjacent areas according to the subframe sets of the ABS of each adjacent area, and informs the UE in each area. According to the measuring and collocation method in the interference coordination mechanism, the UE can measure the adjacent areas in mutual strong interference according to the different measuring subsets, and therefore accurate measurement of the adjacent areas can be achieved.

Description

Measurement collocation method under a kind of interference coordination mechanism
Technical field
The present invention relates to the resource configuration technology in mobile communication system, particularly relate to the measurement collocation method under a kind of interference coordination mechanism.
Background technology
Under heterogeneous network, interference coordination mechanism is the job (Work Item) of 3GPP Rel-11.Heterogeneous network refers to that low power nodes is placed in macro base station coverage area by cloth, forms the heterogeneous system with the different node types covered.Low power nodes (Low Power Node, LPN) micro-base station (Pico) is comprised, remote radio head (Remote Radio Head, RRH), relaying (Relay) and Home eNodeB (HomeeNB, Femto) etc.The technology of the remarkable elevator system throughput of low power nodes energy and overall network efficiency, also can bring extra heterogeneous network presence of intercell interference simultaneously.For the isomery scene of macro base station (Macro)+Pico, employing scope expansion (Range Expansion) technology is considered in Rel-10, namely subscriber equipment (UE) is when macrocell and Microcell carry out community selection or switch, a deviant can be increased in Reference Signal Received Power (RSRP) value of Microcell, namely work as λ pico+ λ bias>=λ macro, UE then selects to access Microcell, otherwise, select access macrocell, wherein λ biasfor deviant, λ picofor the RSRP value from Microcell that UE measures, λ macrofor the RSRP value from macrocell that UE measures.
The employing of Range Expansion technology is equivalent to the coverage artificially expanding Pico base station, the downstream signal of the macro base station that the edge customer (Pico UE1 as shown in Figure 1) therefore under the enlarged area of Pico base station receives will be better than the downstream signal of Pico base station, if do not take effective interference coordination mechanism, the edge customer be in the extended region of Pico base station cannot proper communication.Almost empty frame (ABS) method is the disturbance coordination method that Rel-10 determines, is applicable to FDD and TDD system.Specifically, when being disturbed serious Pico UE when receiving the descending sub frame of Pico base station, macro base station will send ABS subframe, to reduce the down channel interference of edge Pico UE.ABS subframe only comprises district's level reference signal (CRS), channel condition information-reference signal (CSI-RS), Physical Broadcast Channel (PBCH), master sync signal (PSS), auxiliary synchronous signals (SSS), the information such as paging (Paging) and system information block 1 (SIB 1), not transmitting data service.
Be the heterogeneous network scene that an intensive Pico disposes shown in Fig. 2, mutual strong jamming can be there is between Pico under this scene, as Pico1 and Pico2 in Fig. 2.When ABS scheme uses under this scene, Pico1 and Pico2 needs to use the different ABS subframe collection occured simultaneously for sky, to make to be in the Pico UE proper communication that Pico1 and Pico2 covers lap.Now, when Macro UE will measure Pico1 and Pico2, need to carry out on the ABS subframe collection of each base station.If Pico3 is subject to pico4 and Pico5 strong jamming, Pico3UE, to the measurement of Pico4 and Pico5, also needs to configure different measurement subframe collection.But for the configuration of UE to the measurement subframe collection of adjacent cell, current agreement only supports that base station is that UE configures a measurement subframe collection.So under this scene, some UE cannot complete adjacent cell measurement accurately.
As can be seen here, under the macro+pico scene that intensive Pico disposes, when UE needs to carry out adjacent cell measurement to multiple Pico interfered with each other, adopt existing system agreement, UE cannot complete the Measurement accuracy to its adjacent cell.
Summary of the invention
In view of this, main purpose of the present invention is to provide the measurement collocation method under a kind of interference coordination mechanism, and the method can guarantee that UE measures accurately to adjacent area.
In order to achieve the above object, the technical scheme that the present invention proposes is:
A measurement collocation method under interference coordination mechanism, the method comprises the following steps:
A, Operation and Maintenance network element inform to described macro base station by there is mutual strongly disturbing micro-base station Pico in macro base station coverage in advance, and for there is mutual strongly disturbing each described Pico, mutual strongly disturbing adjacent Pico will be there is with this Pico and informing to this Pico;
B, macro base station, according to the disjoint principle of ABS subframe collection adopted between mutual strongly disturbing Pico, are each Pico configuration ABS subframe collection in its coverage;
Mutual strongly disturbing each Pico in c, described macro base station coverage, according to the mutual notice between the notice of described macro base station or adjacent described Pico, knows the described ABS subframe collection of strongly disturbing adjacent Pico with it;
D, when described macro base station need to the UE of this community carry out nearby region measurement configuration time, within the scope of the described ABS subframe collection of each described Pico, determine the measurement subframe collection that each described Pico is corresponding, and inform described UE; When the described Pico that there is the adjacent Pico of strong jamming needs to carry out nearby region measurement configuration to the UE of this community, within the scope of the described ABS subframe collection of each adjacent Pico strongly disturbing with it, determine the measurement subframe collection that each adjacent Pico is corresponding, and inform described UE.
In sum, measurement collocation method under the interference coordination mechanism that the present invention proposes, macro base station is according to the disjoint principle of almost empty frame ABS subframe collection adopted between mutual strongly disturbing Pico, for each Pico in its coverage configures ABS subframe collection, afterwards, each base station is according to the ABS subframe collection of each adjacent area Pico, and the measurement Subset adopted when determining that this community UE measures adjacent area Pico, and informs this community UE.Like this, UE can measure different strong jamming adjacent areas according to different measurement Subset, thus can realize the Measurement accuracy to adjacent area.

Embodiment
For making the object, technical solutions and advantages of the present invention clearly, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Core concept of the present invention is: inform macro base station by Operation and Maintenance network element (OAM) in advance, and be mutually strongly disturbing between which pico in its coverage, OAM also informs pico base station, which has with the mutual strongly disturbing adjacent pico of its existence; Macro base station is that after Pico distributes abs mode, the abs mode that there is strongly disturbing Pico with it also can be known in Pico base station; Then on this basis, macro base station and Pico base station are measured adjacent cell for its UE configures multiple measurement Subset.
Fig. 3 is the schematic flow sheet of the embodiment of the present invention one, and as shown in Figure 3, this embodiment one mainly comprises the following steps:
Step 301, Operation and Maintenance network element (OAM) inform to described macro base station by there is mutual strongly disturbing Pico in macro base station coverage in advance, and for there is mutual strongly disturbing each described Pico, mutual strongly disturbing adjacent Pico will be there is with this Pico and informing to this Pico.
Utilize this step, macro base station can be known in its coverage for which mutual strongly disturbing Pico, and each Pico also can know the mutual strongly disturbing adjacent Pico with its existence simultaneously.In actual applications, can when network construction, OAM carries out described notice, and correspondingly, if the Pico in network there occurs change, OAM also needs to upgrade dynamically.
Step 302, macro base station, according to the disjoint principle of almost empty frame (ABS) subframe collection adopted between mutual strongly disturbing Pico, are each Pico configuration ABS subframe collection in its coverage.
Here, according to the disjoint principle of ABS subframe collection adopted between mutual strongly disturbing Pico, can guarantee that the ABS subframe collection of mutual strongly disturbing each Pico configuration is not identical.
Mutual strongly disturbing each Pico in step 303, described macro base station coverage, according to the mutual notice between the notice of described macro base station or adjacent described Pico, knows the described ABS subframe collection of strongly disturbing adjacent Pico with it.
The ABS subframe collection of this step for making mutual strongly disturbing each Pico know the strong jamming community be adjacent, so that on this basis for this community UE configures the measurement subframe collection of each neighbor cell.
Particularly, this step can adopt following method to realize:
Method one, for strongly disturbing each Pico mutual in described macro base station coverage, the described ABS subframe collection of adjacent Pico strongly disturbing with it, by the base station configuration updating information of X2 interface, is informed to this Pico by described macro base station.
Mutual strongly disturbing each Pico in method two, described macro base station coverage, by the base station configuration updating information of X2 interface, informs to strongly disturbing adjacent Pico with it by the described ABS subframe collection of self.
Said method one achieves and carries out by macro base station the method that notifies, and method two achieves the method by notice mutually between Pico.
Step 304, when described macro base station need to the UE of this community carry out nearby region measurement configuration time, within the scope of the described ABS subframe collection of each described Pico, determine the measurement subframe collection that each described Pico is corresponding, and inform described UE; When the described Pico that there is the adjacent Pico of strong jamming needs to carry out nearby region measurement configuration to the UE of this community, within the scope of the described ABS subframe collection of each adjacent Pico strongly disturbing with it, determine the measurement subframe collection that each adjacent Pico is corresponding, and inform described UE.
Here, utilize the ABS subframe collection of each Pico, determine the measurement subframe collection adopted when this Pico is measured, like this because the ABS subframe collection that ensure that different Pico in step 302 is different, correspondingly, based on this measurement subframe collection corresponding to different Pico obtained also by difference, thus can guarantee that the measurement that UE adopts the different adjacent area of different measuring subframe set pair to carry out does not interfere with each other yet, it is hereby ensured that UE carries out the accuracy of nearby region measurement.
Particularly, the measurement subframe collection that described each described Pico is corresponding can be the complete or collected works of the subset of the described ABS subframe collection of each described Pico or the described ABS subframe collection for each described Pico.
Measurement subframe collection corresponding to described each adjacent Pico can for the subset of the described ABS subframe collection of each adjacent Pico or for measurement subframe collection that each adjacent Pico is corresponding be the described ABS subframe collection of each adjacent Pico.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
