Description

Interference elimination method and device

Technical field

The present invention relates to the communications field, in particular to interference elimination method and device.

Background technology

In radio honeycomb communication system, base station is the equipment of wireless access that provides for subscriber equipment (User Equipment, referred to as UE), and a base station may comprise one or more Serving cells.Community can provide communication service for the UE of certain geographic range, may there be different coverages different communities, conventionally can community be divided into macrocell (macro cell), Microcell (pico cell), picocell (femto cell) etc. according to the object of the coverage of community and deployment, correspondingly, provide the base station of these community user access services to can be described as again macro base station, micro-base station, Home eNodeB etc.Can also there be different access module (access mode) community: a common common community can provide access service for any user, and this community is called open community; And for the demand that needs to limit the user who allows access under the applied environments such as family or enterprise, a closed user group (Closed Subscriber Group, referred to as CSG) community (being called enclosed type (Closed) community) can only allow user's (being member) access of regulation; Or a mixed type (hybrid) community, when being preferably Member Users access is provided, also can provide access service for non-Member Users.

Development along with cordless communication network technology, there will be the scene being covered by two kinds or more of dissimilar communities in identical or adjacent area, for example in Macro Cell coverage, dispose Pico Cell and bear load balancing or coverage enhancement, more for example in Macro Cell coverage domestic consumer also can dispose Femto Cell and bear indoor covering.Thisly by polytype community, jointly complete the scene that wireless access covers and can be called heterogeneous network (heterogeneous network, referred to as hetnet) scene.Under heterogeneous network scene, some new network design scheme and technology constantly occur, for example, in order to allow Pico Cell serve more user also and then to bear more service traffics, can introduce cell edge expansion (Cell Range Extension, referred to as CRE) technology.But, due in cell edge extended area, the Macro Cell's that user is subject to is larger intrusively, in order to reduce the interference for Pico community, under the heterogeneous network scene coexisting at existing Macro Cell and Pico Cell, that can introduce reduce power delivery is almost gap frame (Almost Blank Subframe, referred to as ABS), in order to reduce the interference to adjacent Pico community, Physical Downlink Shared Channel (the Physical Downlink Shared Channel of power on ABS can be avoided as far as possible or reduce in Macro community, referred to as PDSCH) upper transmission downlink service data.

Introduce ABS can partly reduce interfered cell to interfered cell service in interference position, routine CRE described above region, the interference of UE transfer of data, but the transmission that way does not solve all information is disturbed.According to the design in existing system, UE can be based on Serving cell cell reference signals (Cell Specific Reference Signal, referred to as CRS) carry out radio link monitoring (the Radio Link Monitoring of community, referred to as RLM) measure, RRM (Radio Resource Management, referred to as RRM) measure, channel quality indication (Channel Quality Indicator, referred to as CQI) measures.After introducing ABS subframe, interfered cell also has way to guarantee that the UE of earlier version can not carry out described measurement operation in ABS subframe, therefore in order to guarantee that result that earlier version UE measures for ABS subframe does not affect UE and accepts normally service in interfered cell, interfered cell need to still send the CRS signal of normal power in ABS subframe.According to the realization mechanism in existing system, may there are two kinds of identical and not identical scenes in the position distribution of the CRS signal of interfered cell and adjacent interfered cell in subframe.When interfered cell overlaps with the CRS signal location distribution of adjacent interfered cell, in the measurement operating result of the UE that the CRS that interfered cell sends can cause interfered cell service for interfered cell CRS signal, comprise too much interference components, when interfered cell does not overlap with the CRS signal location of adjacent interfered cell, the UE that the CRS that interfered cell sends can cause interfered cell service is subject to serious interference for the data receiver of interfered cell.Further, when having occurred interfered cell simultaneously and interfered cell adjacent with a plurality of interfered cells introduced zero energy or fall in various degree lower powered ABS subframe, the impact that the measurement operation of interfered cell service UE or data receiver operation are subject to will be more serious.

From analysis above, can see, in existing heterogeneous network system, although introduced the problem that the machine-processed data receiver that is disturbed UE (data receiver on PDSCH channel) that can solve to a certain extent interfered cell of ABS is interfered, the CRS transmitting in ABS subframe still exists for the measurement operation based on CRS of interfered cell service UE and the problem that affects of data receiver operation.And the CRS of interfered cell service UE measures the hydraulic performance decline that the affected result of operation causes the service that UE receives at network the most at last, and the problem being interfered during UE data receiver equally also will affect the performance of the service that UE receives in network.

The problem that causes more greatly communication system service performance to decline for interference ratio in transfer of data in correlation technique, not yet proposes effective solution at present.
