Embodiment

In LTE system, employing be that CRS carries out pilot measurement and data demodulates, namely all terminals all use CRS to carry out channel estimating.When adopting the precoding processing mode based on CRS, concrete pre-coding matrix (also can the be called precoding weights) information used when needing transmitting terminal additional notifications receiving terminal data to send, and also the expense of pilot tone is larger.In addition, in multi-user's multiple-input and multiple-output (MU-MIMO, Multi-userMulti-inputMulti-output) system, because multiple terminal uses identical CRS, the orthogonal of pilot tone cannot be realized, therefore, be unable to estimate interference.In addition in LTE system, also introduce user equipment specific reference signal (UE-specificRS, UserEquipment-specificReferenceSignal), it is characterized in that reference signal only exists only in the resource at object UE PDSCH transmission place, and the initialization of the reference signal UE corresponding with current UE to identify (ID) relevant.Here, described UEID can be Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI, Cell-RadioNetworkTemporaryIdentifier).

Long Term Evolution (the LTE-A strengthened, AdvancedLongTermEvolution) in system, in order to reduce pilot-frequency expense and improve channel estimation accuracy, pilot measurement and data demodulates function are separated, respectively define two class reference signals, i.e. demodulated reference signal (DMRS, DemodulationReferenceSignal) and channel state information reference signals (CSI-RS, ChannelStateInformationReferencedSignal).Wherein, CSI-RS is mainly used in channel measurement to obtain channel quality information (CQI, and feed back ChannelQualityInformation), so that base station can utilize this information complete UE scheduling and realize modulation coding mode (MCS, ModulationandCodingScheme) self-adjusted block, does not carry precoding information in the transmission of CSI-RS; And DMRS is mainly used in the Physical Downlink Control Channel (ePDCCH of PDSCH and enhancing, enhancedPhysicalDownlinkControlChannel) channel estimating, to complete the demodulation of data/control channel, the transmission of DMRS carries the precoding information of corresponding PDSCH/ePDCCH, and the initiation parameter of DMRS sequence is determined by DMRS scrambler identity ID (NSCID, DMRSScramblingCodeIDentity) and DMRS initialization of virtual community ID (virtualcellIDentityforDMRS).According to the difference of up-downgoing duplex mode, LTE and lte-a system can be divided into Frequency Division Duplexing (FDD) (FDD, and time division duplex (TDD FrequencyDivisionDuplex), TimeDivisionDuplex) system, the pattern of CSI-RS and DMRS of FDD system and TDD system can difference to some extent.

In LTE system, when the mode based on spatial reuse (spatialmultiplexing) is transmitted, in order to distinguish multiplexing multichannel data, introduce the concept of layer.Wherein, the number of layer of parallel transmission can be less than or equal to port number corresponding to physical channel transmission, each layer represents a circuit-switched data of parallel transmission in spatial multiplexing transmission.There are certain mapping relations between layer and streams of code words, each streams of code words can be mapped to multiple layer, that is each streams of code words signal can corresponding become the signal of multidiameter delay transmission.In LTE system, maximum of each UE supports the transmission of two streams of code words, maximumly can support eight layers.

In LTER8 ~ R11 version, support transmission mode in ten altogether, wherein TM1 ~ TM6 is the transmission mode based on CRS, and TM7 is the transmission mode based on URS, and TM8 ~ TM10 is the transmission mode based on DMRS.The feature interpretation of different transmission mode is as shown in table 1.

Table 1

Meanwhile, support the subframe of two kinds of types of service in LTE system, unicast sub-frame (uncastsub-frame) and MBSFN sub-frame, wherein in LTER8 ~ R10 version, MBSFN sub-frame can only be used for propagating multicast service; MBSFN reference signal is configured, for carrying out the demodulation of PMCH for propagating in Physical Multicast Channel (PMCH, PhysicalMulti-castCHannel) subframe.In LTER11 version, in order to improve resource utilization, support MBSFN sub-frame transmits PDSCH business simultaneously.

In LTER8 ~ R11 version, support three kinds of downlink resource methods of salary distribution, be respectively: Resourse Distribute type0, Resourse Distribute type1 and Resourse Distribute type2; Wherein Resourse Distribute type0 and type1 only supports that centralized resources is dispatched, and Resourse Distribute type2 supports centralized and distributed resource allocation mode simultaneously.The resource distribution mode that different transmission mode is supported is different, and more specifically, different transmission mode is under different descending control signaling information formats (DCIformat), and the resource distribution mode of support is different; In above-mentioned ten kinds of transmission modes, often kind of transmission mode all supports the transmission based on DCIformat1A.In the transmission mode that above-mentioned all DCIformat are corresponding, the PDSCH transmission support resource only having DCIformat1A/1B/1D or 1C corresponding distributes resource distribution mode corresponding to type2.

In LTE system, in order to support, to the adjustment of different terminals PDSCH transmitted power, to introduce P _a, P _btwo parameters, these two parameters are used to indicate the ratio of PDSCHEPRE and CRSEPRE.Due in LTE system, support the power ascension (powerboosting) to CRS, simultaneously in order to ensure the transmitted power consistency of each OFDM symbol, in the OFDM symbol sending CRS, while CRS carries out powerboosting, PDSCH needs to reduce certain power, and then causes in the OFDM symbol of transmission CRS and do not send in the OFDM symbol of CRS, and the EPRE that PDSCH is corresponding there are differences.In order to distinguish this species diversity, respectively define ρ _aand ρ _b; Wherein, ρ _arepresent there is no a CRS OFDM symbol on the ratio of PDSCHEPRE and CRSEPRE, ρ _brepresenting exists in the OFDM symbol of CRS, the ratio of PDSCHEPRE and CRSEPRE, now P _b=ρ _b/ ρ _a.Here, when PDSCH is when based on four antenna transmission diversity transmissions, ρ _a=δ _power-offset+ P _a+ 10log ₁₀(2), otherwise, ρ _a=δ _power-offset+ P _a, wherein δ _power-offsetexcept MU-MIMO transmission pattern, under other transmission modes, value is 0dB; P _afor when not considering four antenna transmission diversity transmission modes and MU transmission mode, the ratio of PDSCHEPRE and CRSEPRE in the OFDM symbol not having CRS.Above-mentioned information is all correspond to the information between object UE and Serving cell on link.

In LTE system, in order to enable Serving cell ,/order instruction (PMI/RI is indicated to the pre-coding matrix of terminal, PrecodingMatrixIndicator/RankIndicator) feedback has certain controlling functions, introduce code book restriction subset, the resource all in whole bandwidth of code book siding stopping set pair is wherein identical.

In LTER11 version, in order to support the elimination (CRS-IC to adjacent cell CRS interference, CRSInterferenceCancellation), Serving cell can by high-level signaling by parameter notifications relevant for adjacent cell CRS to object UE, comprising: the physical Cell ID information of adjacent cell, CRS antenna port information of number and MBSFN sub-frame configuration information; Wherein, MBSFN sub-frame configuration information corresponds to all MBSFN sub-frame configurations of adjacent cell, and the MBSFN sub-frame indicated in system information block (SIB, SystemInformationBlock) with adjacent cell configures identical; , there is not the transmission of CRS signal in the PDSCH territory in MBSFN sub-frame.

In LTER11 version, in order to manage the interference of minizone, introduce the technology of multipoint cooperative, transmission technology based on multipoint cooperative comprises joint transmission (JT, JointTransmission), dynamic node switches (DPS, DynamicPointSwitching), dynamic node is mourned in silence (DPB, DynamicPointBlanking), the technology such as cooperative scheduling and wave beam forming (CSCB, CoordinatedSChedulingandBeam-forming).The basic thought of coordinated multipoint transmission is: by Serving cell to the signal of different node (comprising: base station, community, wireless extension unit (RRH), small-cell (smallcell) and Femto cell (femto-cell) etc.) from sky, time, frequently, power domain coordinates, to avoid causing interference to receiving end signal.Simultaneously in order to reduce the impact on coordinated multipoint transmission resource mapping because CRS position, different districts difference causes, be supported in R11 version in MBSFN sub-frame and transmit PDSCH data, when therefore configuring MBSFN sub-frame in R11 version, can reserve a part of subframe according to demand and be used for PDSCH transfer of data, terminal judges whether current MBSFN sub-frame exists the PDSCH data self needed by the control domain of blind check MBSFN sub-frame.

Multipoint cooperative technology mainly manages interference from Serving cell is coordinated, and in high-load situations, this, is difficult to ensure that cooperation request necessarily obtains corresponding.In this case, the interference cancellation techniques based on receiving terminal receiver just has certain necessity.

In the senior receiver research of receiving terminal, senior receiver mainly can be divided into following several types: least mean-square error-AF panel combines (MMSE-IRC, MinimumMeanSquareError-InterferenceRejectionCombining) (IC is eliminated in receiver, interference, InterferenceCancellation) receiver and maximum likelihood (ML, MaximumLikelihood) receiver.

For MMSE-IRC receiver (supposing based on DMRS), Serving cell needs the initiation parameter (comprising scrambler ID, virtual subdistrict ID, physical district ID etc.) providing the interference DMRS port information that UE uses, DMRS to object UE; For IC and ML receiver, Serving cell, except providing the above-mentioned information required by MMSE-IRC, also needs the modulation system or the MCS information that provide interference source.As can be seen here, if these information being transmitted with eating dishes without rice or wine by the X2 interface of minizone, a large amount of X2 signaling consumptions and space interface signaling expense will be consumed, and comparatively long time delay can be caused, advanced receiver techniques finally can be made to be difficult to be applied in real system.Particularly under the network condition of imperfect back haul link (Non-idealbackhaul), internodal propagation delay time is larger, the dynamic parameters such as picture DMRS port information, modulation system or MCS, are not adapted at transmitting in the X2 interface in non-idealbackhaul situation.

The shortcoming that above-described signaling consumption is large in order to overcome, time delay is large, needs to find new approach and the information such as the initiation parameter needed for senior receiver and dynamic parameter is passed to object UE timely and effectively.For addressing these problems, the associated solutions mentioned comprises:

The first, each community is by the public search space (CSS of PDCCH or ePDCCH, CommonSearchSpace) the PDSCH transmission parameter on each Resource Unit broadcasted, UE directly obtains the PDSCH transmission parameter on each Resource Unit of adjacent cell by the PDCCH/ePDCCH receiving the scrambling of adjacent cell specific scramble codes at the CSS of adjacent cell;

The second, based on PDCCH or ePDCCH CSS and carry out scheduling of resource with specific scrambler scrambling, and scheduling resource on PDSCH, the PDSCH transmission parameter on each Resource Unit is broadcasted; UE at the CSS reception PDCCH/ePDCCH of specific scramble codes scrambling of adjacent cell, and according to the schedule information of PDCCH/ePDCCH, receives corresponding PDSCH, obtains the PDSCH transmission parameter on each Resource Unit of this community.

The third, limit the method for blind check scope based on UE blind check and Serving cell signaling; Particularly, Serving cell can by high-level signaling by the signal deployment of the cell-specific (cell-specific) of adjacent cell to UE, simultaneously Serving cell according to the UE of adjacent cell special (UE-specific) by high-level signaling indicating terminal blind check scope, to needing the parameter area of blind check to limit, thus UE is avoided all parameters to be detected to the complexity issue brought according to complete or collected works.

As can be seen from description above, maximum of UE supports the interference elimination treatment to an adjacent cell.Further, adopting above-mentioned the first and first scheme that terminal can be caused to receive complexity increases greatly, needs repeatedly blind check PDCCH/ePDCCH; And when UE receive interference larger time, the receptivity of PDCCH/ePDCCH and PDSCH to adjacent cell cannot be ensured.In addition, adopt the first scheme, the wasting of resources of CSS can be caused excessive; Adopt first scheme, UE needs to receive multiple PDSCH, and receiving complexity increases.

In LTER10 version, in order to solve macrocell (Macrocell) to the interference problem of smallcell, also introduce the inter-cell interference cancellation (eICIC of enhancing, enhancedInter-CellInterferenceCancellation :) technology, Macrocell sends according to low-power and mourns in silence in the subframe of some, simultaneously smallcell or picocell (picocell) or RRH these Macrocell low-power send or in the subframe of mourning in silence for the user at edge serves.In this case, there is very big-difference in the corresponding on different sub frames strong jamming of the terminal in smallcell.Give an example, in fig. 1 and 2, with frequently between Macrocell and smallcell, and Macrocell is configured with almost blank subframe (ABS, AlmostBlankingSub-frame) subframe, then as shown in Figure 1, in ABS subframe, because Macrocell mourns in silence, so smallcell now can not be subject to the interference of Macrocell, now smallcell priority scheduling edge customer.In order to ensure the covering of edge user, smallcell can adopt higher transmitted power for these edge customer services, and in this case, major embodiment is the interference between smallcell by the interference of the UE under smallcell; And as shown in Figure 2, in non-(non) ABS subframe, because Macrocell will for self covering lower UE transmission data, and due to transmitted power higher, so the interference that the UE under smallcell is subject to is mainly from Macrocell.

In another scene, under TM10 pattern, when system supports the COMP cooperation of DPS mode, due to the change of actual transmissions node, all can change in the QCL hypothesis of resource mapping and antenna, for this reason in R11 version, in physical layer dynamic signaling, introduce PQI mode bit, for dynamically indicating PDSCHREmapping mode and QCL hypothesis.But simultaneously due to the switching of node, interference also may change.Give an example, when transmission access point (AP) switches, now original strong jamming AP becomes the sending node of useful signal; By way of further example, when not carrying out DPB when carrying out DPS, the transmission node of interference and useful signal may exchange.In this case, if directly reconfigure the parameter for NAICS, wireless heterogeneous networks (RRC, RadioResourceControl) signaling consumption can be caused larger.

As can be seen from description above, existing scheme effectively can not be eliminated and suppress the interference between minizone and user.
