Description

A kind of method and apparatus for the treatment of interfering data

Technical field

The present invention relates to communication technical field, particularly relate to a kind of technology for the treatment of interfering data.

Background technology

At present over the mobile network to support the growing demand of the market demand of higher throughput and spectrum efficiency, demand has been driven to go exploitation based on OFDM (OFDM, Orthogonal Frequency Division Multiplexing) forth generation (4G) network, comprise WiMAX (Worldwide Interoperability for Microwave Access, worldwide interoperability for microwave accesses), 3GPP LTE (The3rd Generation Partnership ProiectLong Term Evolution, 3rd Generation Partnership Project Long Term Evolution) and LTE-A (LTE-Advanced).Have the area of intensive community, LTE and LET-A is all interference limiting systems, such as, when the combination of macrocell and picocell is used in heterogeneous network.Therefore, one of the emphasis research topic of LTE and lte-a system is Inter-Cell Interference Coordination (ICIC, inter-cellinterference coordination).

For the discussion of Release-8/9, based on RNTP (Relative Narrowband TXPower, Relative Narrowband TX Power)/HII (High interference Indicator, high interference indicates) ICIC of/OI (Overload Indicator, overload instruction) proposes between macrocell.For the discussion of issuing-10, CoMP (Coordinated Multiple Points, collaborative multicast communication) and almost blank subframe are all proposed for the interference coordination between macrocell and small-cell.For Release-11, in order to further improving performance, there is the specific cell reference signal (CRS of network assistance, cell-specific reference signal) presence of intercell interference (FeICIC, Further enhanced inter-cellinterference) of further enhancing of AF panel/elimination is suggested.But, AF panel/the removing method discussed in Release-11FeiCIC, only be confined to remove adjacent cell CRS to this community PDSCH (Physical Downlink SharedChannel, Physical Downlink Shared Channel) interference, and do not consider the interference elimination method of adjacent cell PDSCH to the interference correspondence of this community PDSCH.

But increase with the business tackling index to improve capacity, more intensive cell deployment (such as heterogeneous network (HetNet, heterogeneous network)) and the spectrum efficiency improved are all necessary.For realizing higher network capacity, no matter being disturb from the cochannel of the user in minizone or common community of dispatching, all estimating the key constraints becoming the higher network capacity of realization.Compared with the coordination of transmission equipment side, AF panel or the cancellation of receiving terminal also can show significant performance gain.Serial interference elimination (SIC, Successive interferencecancellation) and parallel interference canceller (PIC, Parallel interference cancellation) have been proved to be in academia and can provide outstanding performance.Recognize these benefits, the research project that RAN#59 approved one is new, network assistance interference about the Release-12 of LTE is eliminated and suppresses (NAICS, Network-Assisted Interference Cancellation andSuppression), to assess its benefit, and inquire into the feasible method of NAICS.

In NAICS, network provides the downlink transfer information of interfered cell to disturbed UE, so that this disturbed UE can perform interference eliminate/suppress (IC/IS).We with reference to downlink transfer information as NAICS information.NAICS information sends to disturbed UE by the Serving cell of the first mechanism as shown in Figure 1, or sends to disturbed UE by the interfered cell of the second mechanism as shown in Figure 1.Consider the dynamic characteristic of scheduling, and the coordination that between base station between the community that relates to of NAICS and the Serving cell of disturbed UE, mutual corresponding interface X2 link postpones, the second mechanism may more efficiently with effective in implementation process.

In RAN1#73, agree unanimously that NAICS will focus on PDSCH physical channel.Therefore, NAICS informational needs provides the decoding of the PDSCH (s) in interfered cell (as modulation & TBS (Transport Block Size, transmission block size)) information and schedule information (position of PRBs (Physical Resource Block, Physical Resource Block)).It can quilt:

Direct transmission, such as, to comprise about the interference decoding of PDSCH and (E) PDCCH ((Enhanced) Physical Downlink Shared ControlChannel of schedule information, (enhancing) Physical Downlink Control Channel) form, namely all schedule informations that control signal (E) PDCCH comprises directly are issued disturbed UE and are performed NAICS by this kind of mode;

Between receive and send, such as, NAICS packets of information is containing the interference UE ID of PDSCH and the community ID of interfered cell, UE decodes (E) PDCCH to obtain decoding and the schedule information of interference PDSCH by using the UE ID (as C-RNTI) of this transmission, namely the UE-ID (as C-RNTI) of the UE producing interference only issues and is disturbed UE by this kind of mode, is disturbed the decoding that UE only does schedule information on this basis.

Between to receive and send be attracting, because of its minimized information content sent, because this reducing the resource overhead be used in NAICS information.For the UMTS using NAICS, this indirect method is also recommended.No matter whether NSICS information is sent directly between or receives and sends between quilt, PDSCH decoding and schedule information are as (E) PDCCH, by disturbed UE blind decoding (BL, blindly decoded), to bring flexibility to eNB scheduling, if but this disturbed UE needs to carry out NAICS, need to separate the control signal of code book community and the control signal causing the UE of interference corresponding to adjacent cell, this will increase the blind check complexity of disturbed UE simultaneously.
