Parameter Details

Most of the parameters are the same as in LTE_DL_ChannelCoder (ltebasever). Followingare the new/updated parameters in LTE_A_DL_ChannelCoder.

UE_RevMode: the release version of the UE1.If the RevMode is set to 0(Release 8 LTE), the NumOfLayers should be in the range[1,4]. The NumOfLayers should be equal to CRS_NumAntPorts.If the RevMode is set to 1(Release 10 LTE Advanced), the NumOfLayers should be inthe range [1,8].CRS_NumAntPorts: number of cell specific antenna ports (port 0, 1, 2, 3). It can be2.selected from {CRS_Tx1, CRS_Tx2, CRS_Tx4}.DMRS_NumAntPorts: number of antenna ports to transimt the UE-specific reference3.signals. This parameter is vaild when RevMode=1(Release 10 LTE Advanced).MIMO_Mode: specifies the MIMO mode.4.

Notes/Equations

This subnetwork performs LTE Advanced downlink channel coding with the optional1.closed-loop HARQ transmission. Data streams from MAC layer are encoded to offertransport services over the radio transmission link. Channel coding scheme is acombination of error detection, error correcting, rate matching, interleaving andtransport channel mapping onto physical channels.Each firing, variant tokens are consumed at the DataIn port based on the transport2.block size (A) and HARQ ACK/NACK bit. If the transmission of new transport block isneeded in this subframe (firing), the number of tokens consumed is the transportblock size (A); otherwise, no token is consumed in this subframe (firing). Refer toClosed-loop HARQ Transmission (ltebasever).One token is consumed at the HARQ_Bits port, where 1 indicates CRC check success,0 indicates CRC check failure. When HARQ_Enable is set NO, this port could beunconnected and no data is read from this port; when HARQ_Enable is set YES, thedata is read from this port when this port is connected, and the value '1' (HARQ ACK)is assumed when this port is unconnected. Note that it is required that the HARQACK/NACK bits input to this port should be delayed by NumHARQ when HARQ_Enableis set YES.One Matrix-based token is produced at the DataOut port. The matrix vector size isthe number of channel bits (G) for this subframe (firing). For more information, referto Relation of Transport Block Sizes, Channel Bits and Code Rates (ltebasever).One token is produced at the Qm port, indicating the modulation order for thissubframe (firing), where 2 means QPSK, 4 means 16QAM and 6 means 64QAM.The schematic LTE_A_DL_ChannelCoder is shown below,3.

The subnetwork includes LTE_CRCEncoder, LTE_CodeBlkSeg, LTE_TurboCoder,4.LTE_RateMatch, LTE_Scrambler and LTE_A_HARQ_Controller, which perform CRCattachment, code block segmentation, turbo encoding, rate matching, PDSCHscrambling and HARQ control signal generation respectively for both FDD and TDD.For more information, pls. refer to LTE_DL_ChannelCoder (ltebasever).5.

Notes/Equations

This model is used to control HARQ transmission for downlink/uplink transport1.channels, which generates HARQ control signals such as transport block size,retransmission number using the HARQ ACK/NACK feedback from the receiver. LTEAdvanced closed-loop HARQ simulation employs dynamic data flow. Refer to DynamicData Flow Simulation (sim) for how dynamic data flow and closed-loop HARQ


22

simulation work collaboratively.Compared to LTE_HARQ_Controller (ltebasever), the updates in this model are as2.follows.

For downlink, parameter UE_RevMode is added to indicate the release version ofthe PDSCH.

If it is set to 0:Release 8, the implementation of this model is the same asLTE_HARQ_Controller (ltebasever).If it is set to 1:Release 10, in the calculation of available REs for PDSCHtransmission, the REs occupied by DMRS (port 7~ 14) is precluded.CRS_NumAntPorts indicates the number of antenna ports for cell specificreference signals.NumOfLayers indicates the number of layers for this codeword of PDSCH.DMRS_NumAntPorts indicates the number of DMRS antenna ports.

For uplink, this model also supports multiple layers as in downlink.See LTE_HARQ_Controller (ltebasever) for more information.3.

Parameter DetailsMost of the parameters are the same as in LTE_BER_FER (ltebasever), following are thenew/updated parameters in LTE_A_BER_FER,

CRS_NumAntPorts: number of antenna ports to transmit the cell specific reference1.signals. It can be selected from {CRS_Tx1, CRS_Tx2, CRS_Tx4}.DMRS_NumAntPorts: number of antenna ports to transmit the UE-specific reference2.signals. It can be set in the range [1, 8].UE_RevMode: the release version of each UE. For Release 10 mode, only Spacial3.Multiplex is supported for downlink.

Notes/Equations

This model can be used to measure the bit error rate (BER) and frame error rate1.(FER) of both LTE Advanced downlink and uplink input data streams. FER issometimes referred to as PER (packet error rate) or BLER (block error rate). HereFER actually stands for subframe error rate. A subframe is considered to be in error ifat least one of the bits in the subframe is detected incorrectly.Both downlink and uplink BER/FER can be measured. The functionality of this model2.is like the LTE_BER_FER model except for the following enhancement,

LTE Release 10 for Downlink special multiplex, 1 transmit antenna with DMRSfor PDSCH, 2 transmit antennas upto 2 codewords and 2 layers with DMRS forPDSCH, 4 transmit antennas upto 2 codewords and 4 layers with DMRS forPDSCH and 8 transmit antennas upto 2 codewords and 8 layers with DMRS forPDSCH.LTE Release 10 for Uplink MIMO, 2 transmit antennas upto 2 codewords and 2layers for PUSCH, 4 transmit antennas upto 2 codewords and 4 layers forPUSCH.


40

The typical use of this model can be found in the example workspace3.LTE_Advanced_DL_SISO_BER.wsv and LTE_Advanced_UL_SISO_BER.wsv.For more information, please refers to LTE_BER_FER (ltebasever).4.

Notes/Equations

This model is used inside the LTE_A_DL_Src model for LTE Advanced Downlink,1.serving two functions:

Validate the input parametersReport some useful internal inforamtion based on the input parameters

When the parameter DisplayMsg = None, no message is shown;When the parameter DisplayMsg = Simple, the System Configurations andUE-specific Configurations are output;When the parameter DisplayMsg = Full, the System Configurations, UE-specific Configurations and Power are output. Note that the transmit powerfor the OFDM symbols allocated to PDCCH is calculated with the assumptionthat all resource elements (REs) allocated to PDCCH are occupied withQPSK symbols. When some of the resource elements (REs) allocated toPDCCH are empty, the actual transmit power will be lower than the powerabove.

There is no input and output port in this model.2.For the description for all input parameters, please refers to LTE_A_DL_Src3.(lteabasever).


44

When users want to test a set of parameters for LTE Advanced Downlink, they can4.run this model alone. Then the error messages are shown if parameters are wrong,or the useful intenal messages are shown based on DisplayMsg setting if parametersare correct.See also LTE_DL_Src_RangeCheck (ltebasever).

Notes/Equations

This model is used to implement MIMO deprecoding for both spatial multiplexing and1.transimit diversity for both Release 8 and Release 10 UE. It is the inverse ofLTE_A_DL_MIMO_Precoder (lteabasever). This model is similar toLTE_DL_MIMO_Deprecoder. Please refer to LTE_DL_MIMO_Deprecoder (ltebasever).What different with LTE_DL_MIMO_Deprecoder are as follows:2.

New added parameters:UE_RevMode defines the release version of this UE, 0 for Release 8 and 1for Release 10.If this parameter is set to 0, this model will work same asLTE_DL_MIMO_Deprecoder except that the parameter NumTxAnts ofLTE_DL_MIMO_Deprecoder is replaced with CRS_NumAntPorts. And in thiscase the NumOfLayers is not support 8.If this parameter is set to 1, this model will work for Release 10 UE. In thisphase, the PMI port is not supported at this phase. For Release 10 UE, ifMIMO_Mode is set to Spatial_Mux the precoding matrix is defined byparameter PrecodingMatrix; and if MIMO_Mode is set to TD, it works sameas the Release 8 UE and the number of layer must same as the theCRS_NumAntPort.UserDefinedPrecoder defines whether to use user-defined precoding matrixas specified in PrecdongMatrix or not. In this phase, if UE_RevMode is setto 1, and MIMO_Mode is set to 0, UserDefinedPrecoder must be set to YES.PrecodingMatrix defines the precoding matrix for Release 10 UE. Thisparameter is a complex array parameter which has the size ofNumOfLayers*NumOfLayers in case of MIMO_Mode is set to Spatial_Mux.

Changed parameters:the parameter NumRxAnts can be set 8 Antennas and so the multiportinput port MIMO_Symbol can be expanded to 8.the parameter NumOfLayers can be set to 8 in case of UE_RevMode is setto 1 and so the multiport output port Layer_Symbol can be expanded to 8.

Notes/Equations

The precoder takes as input a token of vectors from the layer mapping and generates1.a token of vectors to be mapped onto resources on each of the antenna portsaccording to Section 6.3.4 in [1].

If parameter UE_RevMode = 1 and MIMO_Mode = Spatial multiplexing, thismodel perform precoding for spatial multiplexing using antenna ports with UE-specific reference signals according to Section 6.3.4.4. In this case, theprecoding matrix can be user-defined by set parameterUserDefinedPrecoder=YES and set PrecodingMatrix correctly.Otherwise, this model is same as LTE_DL_MIMO_Deprecoder except that theparameter NumTxAnts in LTE_DL_MIMO_Precoder is replaced withCRS_NumAntPorts. Please refer to LTE_DL_MIMO_Precoder (ltebasever).

What different with LTE_DL_MIMO_Precoder are as follows:2.New added parameters:

UE_RevMode defines the release version of this UE, 0 for Release 8 and 1for Release 10.CRS_NumAntPorts defines the number of antenna ports.UserDefinedPrecoder defines whether to use user-defined precoding matrixas specified in PrecdongMatrix or not. If UE_RevMode = 1, and MIMO_Mode= 0, parameter UserDefinedPrecoder is active.PrecodingMatrix provides user-defined precoding matrix in the case thatUE_RevMode = 1, MIMO_Mode = Spatial multiplexing andUserDefinedPrecoder=YES. This parameter is a complex array parameterwhich has the size of NumOfLayers*NumOfLayers.

Changed parameters:the parameter NumOfLayers can be set to 8 in case of UE_RevMode = 1and MIMO_Mode = Spatial multiplexing and so the multiport port can beexpanded to 8.

It is the inverse of LTE_A_UL_MIMO_Precoder (lteabasever).Each firing, one Matrix-based token is consumed at each bus of the MIMO_Symbol2.port whose bus width is equal to the number of Rx antennas (determined byNumRxAnts). The matrix vector size for each bus, donated B.One Matrix-based token is consumed at the CIR port when this port is connected. Thematrix vector size should be equal to NumTxAnts*NumRxAnts*B, where NumTxAntsand NumRxAnts are the number of transmit antennas and the number of receiverantennas respectively.One Matrix-based token is produced at each bus of the Layer_Symbol port whose buswidth is equal to NumOfLayers. The matrix vector size for each bus is the same as B.The SubframeIgnored parameter specifies how many tokens are ignored at the3.beginning of simulation. In the first SubframeIgnored tokens, the matrix size at eachbus of the Layer_Symbol port is 0.When this CIR port is connected, the H matrix is constructed from this port, with the4.size of NumTxAnts*NumRxAnts. Otherwise, the identity matrix is constructed for Hmatrix.(Zero Forcing) algorithm is employed in this model.5.See also LTE_A_UL_MIMO_Precoder (lteabasever).6.

Notes/Equations

This model is used to constitute LTE Advanced FDD and TDD downlink OFDM Symbol.1.It multiplexes control channels PCFICH, PHICH PDCCH and PBCH), synchronizationsignals (PSS, SSS, RS and DMRS) and data channels PDSCH1 to PDSCH6 into oneOFDM frame. This model is similar with LTE_DL_MuxOFDMSym except that there arenew added DMRS for Release 10 UEs. Please refer to LTE_DL_MuxOFDMSym(ltebasever).What different with LTE_DL_MuxOFDMSym are as follows:2.

New added parameters:


116

CRS_NumAntPorts defines the number of CRS antenna ports.UEs_RevMode defines the release version of each UE, 0 for Release 8 and 1for Release 10.UEs_NumOfLayers defines the number of layer for each UE, the number oflayers for Release 10 UE, can be expanded to 8 in case of NumTxAnts setto Tx8.DMRS_Ra defines the UE specific power parameter for each UE.AntMappingMatrix specifies the user-defined antenna mapping matrix.For more details please refer to LTE_A_NewAddedParameters(lteabasever).

Changed parameters:the parameter NumTxAnts can be set to 8 Antennas and so the input andoutput port can be expanded to 8.

Changed functionalityThe Downlink Resource Grid is same as 3GPP LTE System. The controlchannel, PHICH, PCFICH, PDCCH and PBCH are mapped to the resourceelements same as the LTE. The physical signals, the primary synchronizationsignal (PSS), the secondary synchronization signal (SSS) and the CRS aremapped to the resource elements same as the LTE.But for LTE Advanced, there are new added DMRS for each Release 10 UE thatneed mapped to the resource elements. Figure 6.10.3.2-3 in [1], illustrates theresource elements used for UE-specific reference signals for normal cyclic prefixfor antenna ports 7, 8, 9 and 10.

Figure 6.10.3.2-4 illustrates the resource elements used for UE-specificreference signals for extended cyclic prefix for antenna ports 7, 8.


117

If the REs labeled in these figures above are allocated for other physicalchannel/signals (such as PSS), there will be no DMRS.

For all the input and output multiple ports, the bus width should be equal to the3.number of Tx antennas which defined by NumTxAnts parameter.For ith firing, Subframe#(i%10) is processed, where 10 is the number of subframesin one radio frame.

Each firing, for each antenna port, one Matrix-based token is consumed at eachinput port.The matrix vector sizes needed at ports Data_UEx (x is 1~6) are equal to thenumber of resource elements (REs) allocated to this UE (PDSCH) in one radioframe (10 subframes). For more information on how to get the number ofallocated REs given the UEx_RB_Alloc parameter (x is 1~6), refer to ResourceBlock Allocation (lteabasever) and Channel Bits Calculation (lteabasever).For other control channels, the matrix vector sizes needed at correspondinginput ports are equal to the number of resource elements (REs) allocated tocontrol channels.For DMRS_UEx (x is 1~6), which are optional, if there are Release 10 UEs,corresponding DMRS port for this UE is must connected. The matrix vector sizesneeded at corresponding input ports are equal to the number of resourceelements (REs) allocated to this UE’s DMRS.For output ports, the number of tokens produced is equal to the number ofresource elements (REs) in one subframe, determined by the Bandwidth andCyclicPrefix parameter.

For each channel, when the input matrix vector size is less than the desired matrix vectorsize, an error message will be given, showing the desired matrix vector size and the actualmatrix vector size which are helpful for troubleshooting.when the input matrix vector size is greater than the desired matrix vector size, thesimulation will continue and the desired data are collected from the beginning of the inputmatrix vector.

The output at port SC_Status is the status for each subcarrier (resource element).4.The first value is the status for the first subcarrier (resource element) in the firstOFDM symbol, and then the second is for the second subcarrier (resource element) inthe first OFDM symbol. When the last subcarrier (resource element) in the first OFDMsymbol is output, then next the first subcarrier (resource element) in the secondOFDM symbol is output, and so on. The 8 LSB bits of each status value represent thechannel type allocated on each subcarrier (resource element). The meaning of the8 LSB bits is shown in the table below:

Notes/Equations

This model is used to de-multiplex UL frames into physical channels and physical1.signals. PUSCH, PUCCH, DMRS for PUSCH, DMRS for PUCCH and Sounding referencesignals are output. This model is similar with LTE_UL_DemuxSCFDMASym. Pleaserefer to LTE_UL_DemuxSCFDMASym (ltebasever).What different with LTE_DL_MuxOFDMSym are as follows:2.


NumTxAnts defines the number of Tx antennas. In this model, NumTxAntsdecides the antenna ports used for PUCCH transmission. If number of Txantenna is Tx1, the antenna ports used for PUCCH is 1, otherwise, 2.NumRxAnts defines the number of Rx antennas. NumRxAnts can be set toRx1, Rx2 or Rx4, and so the input and output ports are multiport which canbe expanded to 2 or 4.

Changed parameters:PUCCH_n1 defines the resources used for transmission PUCCH format1/1a/1b on each antenna port.PUCCH_n2 defines the resources used for transmission PUCCH format2/2a/2b on each antenna port.These 2 parameters can have the size 1x1 or 1xNumOfPUCCHAntPorts. Ifthey have size 1x1, it means that same resources are used for PUCCH(s)transmitted on each antenna port. For more details, please refer toLTE_A_NewAddedParameters (lteabasever).

Each firing,3.NumberREsPerSubframe tokens are consumed at each bus of port Input, whereNumberREsPerSubframe is the total number of REs in each subframe.NumberREsPerSubframe = NumOfTotalRBs * 12 (subcarriers per RB) *NumberOfSymbolsPerSubframe.1 matrix token is produced at each bus of port PUSCH_Sym, the size of thematrix token is equal to the number of REs allocated for PUSCH transmission inthis subframe. If PUSCH is not transmitted in this subframe, the output matrixtoken is empty.1 matrix token is produced at each bus of port PUCCH_Sym, the size of thematrix token is equal to the number of REs allocated for PUCCH transmission inthis subframe. If PUCCH is not transmitted in this subframe, the output matrixtoken is empty.1 matrix token is produced at each bus of port PUSCH_RS, the size of the matrixtoken is equal to the number of REs allocated for PUSCH DMRS transmission inthis subframe. If PUSCH is not transmitted in this subframe, the output matrixtoken is empty.1 matrix token is produced at each bus of port PUCCH_RS, the size of the matrixtoken is equal to the number of REs allocated for PUCCH DMRS transmission inthis subframe. If PUCCH is not transmitted in this subframe, the output matrixtoken is empty.1 matrix token is produced at each bus of port SRS, the size of the matrix tokenis equal to the number of REs allocated for SRS transmission in this subframe. IfSRS is not transmitted in this subframe, the output matrix token is empty.1 matrix token is produced at each bus of port RBOut, the size of matrix token isequal to the number of REs allocated for PUSCH and PUCCH transmission.For the default parameter configurations, NumberREsPerSubframe = 7200; thesize of matrix token output at PUSCH_Sym is 3600; the size of matrix tokenoutput at PUSCH_RS is 600; the matrix tokens output at PUCCH_Sym andPUCCH_RS are empty; the matrix token output at SRS is empty; the size ofmatrix token output at RBOut is 3600.

Port RBout output data symbols transmitted in each allocated RB for PUSCH and4.PUCCH. Reference signals are not output from this port.For the first SubframeIgnored subframes(firings), this model does nothing on the5.input but produces empty tokens at all output ports.It should be noted that the parameter DFTSwap_Enable should be set to NO6.according to the LTE Advanced specifications.See LTE_A_UL_MuxSCFDMASym (lteabasever).7.

Parameter Details

Most of the parameters are the same as in LTE_DL_Receiver (ltebasever),LTE_DL_MIMO_2Ant_Rcv (ltebasever) and LTE_DL_MIMO_4Ant_Rcv (ltebasever).Following are the new/updated parameters in LTE_A_DL_Rcv.

NumRxAnts: number of receive antennas. Up to 8 receive antennas can be supportedin LTE-A DL receiver.

The new/updated parameters in LTE Advanced library can be found in LTE_A_DL_Src(lteabasever).

Notes/Equations

This subnetwork implements 3GPP LTE Advanced downlink FDD/TDD baseband1.receiver.The LTE_A_DL_Rcv schematic is shown below:2.


142

This subnetwork can be configured as LTE Advanced downlink receiver with single3.receive antenna, 2 receive antennas, 4 receive antennas and 8 receive antennas,which is determined by NumRxAnts. Together with LTE_A_DL_Src (lteabasever), upto 8 × 8 LTE Advanced MIMO solution can be easily provided.Only ZF (Zero Forcing) MIMO decoder is supported. MMSE MIMO decoder has not4.been supported yet.Linear and MMSE channel estimation are supported. For the demodulation of PDSCH5.of Release 10 UE, the DMRS (UE specific reference signals, port 7~14) are used inthe channel estimation. For the demodulation of PDSCH of Release 8 UE and theother physical channels (e.g. PCFICH, PHICH, PDCCH, PBCH), the CRS (Cell specificreference signals, port 0~3) are used in the channel estimation. The channelestimation using DMRS is only implemented for UE 1. Hence, if UE2~UE6 are selectedas Release 10 UE, the PDSCH of this UE may not be correctly demodulated.

If the first UE is selected as Release 10 UE, and the RB allocation for UE1 overlapped with PSS, SSSor PBCH, the DMRS would not be transmitted on those symbols. Then the receiver can’t get accuratechannel estimation on those RBs and the PDSCH transmitted on those RBs may not be demodulatedcorrectly in current implementation. Hence the overlap of Release 10 PDSCH and PSS, SSS andPBCH should be avoided.

Parameter Details

Most of the parameters are the same as in LTE_DL_Src (ltebasever),LTE_DL_MIMO_2Ant_Src (ltebasever) and LTE_DL_MIMO_4Ant_Src (ltebasever).Following are the new/updated parameters in LTE_A_DL_Src.

CyclicPrefix: only Normal Cyclic Prefix is supported in LTE-A downlink in currentSystemVue implementation.UEs_RevMode: the release version of each UE. It is a vector of length 6corresponding to six UEs in the DL source. Each of the six elements can be set to 0 or1, in which 0 indicates Release 8 and 1 indicates Release 10.


162

For each UEIf the RevMode is set to 0(Release 8 LTE), the MIMO_Mode can be selected as 0(SM, SpatialMultiplexing) or 1(TD, Transmit Diversity). The NumOfLayers should be in the range [1,4].The precoding is according to sub clause 6.3.4.2 (Precoding for spatial multiplexing usingantenna ports with cell-specific reference signals) and sub clause 6.3.4.3 (Precoding fortransmit diversity)[1]. The implementation of layer mapping and precoding is the same as inLTE_DL_MIMO_2Ant_Src (ltebasever) and LTE_DL_MIMO_4Ant_Src (ltebasever). If thenumber of CRS antenna ports (CRS_NumAntPorts) is less than the number of physicaltransmit antennas (NumTxAnts), virtual antenna mapping is employed to map the antennaports onto the Tx antennas. If UserDefinedAntMappingMatrix is set to 1:YES,CRS_AntMappingMatrix is used for Release 8 UE.If the RevMode is set to 1(Release 10 LTE Advanced), the MIMO_Mode is fixed to 0(SM,Spatial Multiplexing). The NumOfLayers should be in the range [1,8]. The precoding isaccording to sub clause 6.3.4.4 (Precoding for spatial multiplexing using antenna ports withUE-specific reference signals)[1]. If the number of layers (NumOfLayers[ueId]) is less thanthe number of physical transmit antennas (NumTxAnts), virtual antenna mapping is employedto map the antenna ports onto the Tx antennas. If UserDefinedAntMappingMatrix is set to1:YES, UE#ueID_AntMappingMatrix is used for each Release 10 UE.In other words,

to implement precoding for spatial multiplexing using antenna ports with cell-specificreference signals [1], please set UEs_RevMode[ueID] to 0 (Release 8) and setUEs_MIMO_Mode[ueID] to 0 (SM).to implement precoding for transmit diversity)[1], please set UEs_RevMode[ueID] to 0(Release 8) and set UEs_MIMO_Mode[ueID] to 1 (TD).to implement precoding for spatial multiplexing using antenna ports with UE-specificreference signals)[1], please set UEs_RevMode[ueID] to 1 (Release 10) and setUEs_MIMO_Mode[ueID] to 0 (SM).

NumTxAnts: number of transmit antennas. Up to 8 transmit antennas can besupported in LTE-A DL source.CRS_NumAntPorts: number of cell specific antenna ports (port 0, 1, 2, 3). It can beselected from {CRS_Tx1, CRS_Tx2, CRS_Tx4}.UserDefinedAntMappingMatrix: whether to configure the virtual antenna mappingmatrix manually.

If it is set to NO, the default matrixes are used. By default, for Release 8 UE, theCRS antenna ports (port 0, 1, 2, 3) are mapped onto the first CRS_NumAntPortstransmit antennas; for Release 10 UE, the antenna ports with UE-specificreference signals (port 7~14) are mapped on to the first NumOfLayers[ueID]transmit antennas;If it is set to YES, for Release 8 UE, the matrix specified inCRS_AntMappingMatrix is used; for Release 10 UE, the matrix specified inUE#ueID_AntMappingMatrix is used.

CRS_AntMappingMatrix should be set as a matrix with NumTxAnts rows andCRS_NumAntPorts columns.For Release 10 UE, the matrix UE#ueID_AntMappingMatrix should be set as a matrixwith NumTxAnts rows and NumOfLayers[ueID] columns.The lines are separated by semicolons, while the elements within each line areseparated by commas.It should be noted that the antenna mapping matrixes configured by these parametersare directly used in the virtual antenna mapping without any additional powernormalization.

UEs_n_SCID: the scrambling identity for each UE. It is used in the generation ofDMRS on port 7 and 8.DMRS_Ra: DMRS to CRS EPRE ratio in dB for each UE.

Notes/Equations

This subnetwork generates 3GPP LTE Advanced FDD (FS1) and TDD (FS2) coded1.downlink baseband signal (up to six users (PDSCHs)).The LTE_A_DL_Src schematic is shown below:2.


163

This subnetwork can be configured as LTE Advanced downlink source with single3.transmit antenna, 2 transmit antennas, 4 transmit antennas and 8 transmitantennas, which is determined by NumTxAnts. Together with LTE_A_DL_Rcv(lteabasever), up to 8 × 8 LTE Advanced MIMO solution can be easily provided.There are several MIMO related parameters, i.e. UEs_MIMO_Mode, UEs_CDD_Mode,4.UEs_ Cdblk_Index, UEs_NumOfCWs and UEs_NumOfLayers.For UE i,

If UE i is Release 8 UE, i.e. UEs_RevMode[i] = 0, UEs_MIMO_Mode[i] can be setto 0(SM, Spatial Multiplexing) and 1(TD, Transmit Diversity).

If SM is configured, the cyclic delay diversity mode (UEs_CDD_Mode[i]) canbe set to 0(Large-Delay) and 1(Zero-Delay). If Zero-Delay is configured,the code book (UEs_Cdblk_Index[i]) can be selected from Table 6.3.4.2.3-1and Table 6.3.4.2.3-2 [1]. The number of codewords (UEs_NumOfCWs[i])can be set to 1 or 2. The precoding of PDSCH is according to6.3.4.2(Precoding for spatial multiplexing using antenna ports with cell-specific reference signals) [1].If TD is configured, the number of codewords (UEs_NumOfCWs[i]) is fixedto 1. The precoding is according to 6.3.4.3(Precoding for transmit diversity)[1].The number of layers (UEs_NumOfLayers[i]) is limited byCRS_NumAntPorts. The maximum number of layers is 4.

If UE i is Release 10 UE, i.e. UEs_RevMode[i] = 1, UEs_MIMO_Mode[i] is fixed to0(SM, Spatial Multiplexing). UEs_CDD_Mode[i] and UEs_Cdblk_Index[i] are notused. The number of codewords (UEs_NumOfCWs[i]) can be set to 1 or 2. Theprecoding of PDSCH is according to 6.3.4.4(Precoding for spatial multiplexingusing antenna ports with UE-specific reference signals) [1]. The number oflayers (UEs_NumOfLayers[i]) is limited by NumTxAnts. The maximum number oflayers is 8.

For all physical signals and physical channels except PSS and SSS, virtual antenna5.mapping is implemented to map the antenna ports onto the physical transmitantennas. For PDSCH of Release 10 UE, the corresponding UE#ID_AntMappingMatrixis used. For PDSCH of Release 8 UE, PDCCH, PHICH, PCFICH, PBCH and CRS,CRS_AntMappingMatrix is used.For more information, pls. refer to LTE_DL_Src (ltebasever), LTE_DL_MIMO_2Ant_Src6.(ltebasever) and LTE_DL_MIMO_4Ant_Src (ltebasever).Close loop precoding with PMI feedback has not been supported in LTE-A library yet.7.The Spectrum shaping is employed on all transmit antennas by default. Open the8.LTE_A_DL_Src by right clicking the model and selecting open->Model/Subcircuit, findthe SpectrumShaper(LTE_A_SpecShaping (lteabasever)), set the parameterSpecShapingAntNum, then the spectrum shaping is performed only for the firstSpecShapingAntNum transmit antennas. It can decrease the required memory insimulation.

Notes/Equations

This subnetwork generates LTE Advanced uplink baseband signal for both frame1.structure type 1 and frame structure type 2.The LTE_A_UL_Src schematic is shown below:2.

This subnetwork can be configured as LTE Advanced uplink source with single3.transmit antenna, 2 transmit antennas and 4 transmit antennas, which is determinedby NumTxAnts. Together with LTE_A_UL_Rcv (lteabasever), up to 4 × 4 LTEAdvanced MIMO solutions can be easily provided.Simultaneous PUCCH and PUSCH transmission is supported. Set parameter4.PUCCH_PUSCH to 2:both, then the PUCCH and PUSCH can be transmitted on thesame subframe. However, there should be no conflict between the RB allocation forPUSCH and PUCCH.Cluster SC-FDMA is supported. Set RB_AllocType to 1:RB indices(1D) or 2:RB5.indices(2D), then non-contiguous RB allocation can be accepted by RB_Alloc. Formore information, please refer to Resource Block Allocation (ltebasever).For PUCCH, it can be transmitted on one or two antenna ports in current6.implementation. Virtual antenna mapping is employed when the number of transmitantennas is larger than 2. The antenna mapping matrix PUCCH_AntMappingMatrixcan be configured in the Equation of the LTE_A_UL_Src. Right click theLTE_A_UL_Src model, choose open->Model/Subnets and navigate to the Equationtab. Find the PUCCH_AntMappingMatrix on line 11.For PRACH, virtual antenna mapping is employed to map it from single port onto7.multiple transmit antennas. It is only transmitted on the first antenna by default. Theantenna mapping matrix PRACH_AntMappingMatrix can be configured in the Equationof the LTE_A_UL_Src.

Notes/Equations

This model is used to estimate 3GPP LTE downlink channel response (CR) with the1.DM-RS symbols assisted for both FDD and TDD schemes. The downlink UE-specificreference signals (DM-RS) are based on 1 .Each firing,2.

1 matrix token is consumed at port DMRS, the size of the pth matrix token isequal to the number of DM-RS REs for the antenna port p in each subframe, formore information, please refer to LTE_A_DL_DMRS.NumberREsPerSubframe tokens are consumed at each port of the multiportinput, NumberREsPerSubframe = NumOfRBs * 12 (subcarriers per RB) *NumberOfSymbolsPerSubframe, where NumOfRBs is the number of resourceblocks assigned to the UE.NumberREsPerSubframe * NumberOfLayers * NumberRxAnts tokens areproduced at port Coef, where NumberOfLayers is the number of layers andNumberRxAnts is the number of Rx antennas.

Linear interpolation and MMSE interpolation are supported in this channel estimator.3.Channel estimation is done on a subframe basis.The least-squares CR estimate at a pilot location ( i ) can be obtained as:4.Hi = Yi / Xi, where Yi is the received Pilot symbol and Xi is the transmitted Pilot

symbol on the ith subcarrier.After getting the CRs at pilot locations, an interpolation algorithm is used to obtain all5.CR estimations.

If ChEstimatorMode is set to Linear, linear interpolation in frequency domain isperformed to get CEs in all subcarriers in DM-RS OFDM symbols, then do linearinterpolation in time domain is performed to get CEs in all other OFDM symbols.If ChEstimatorMode is set to MMSE_2D, two-dimensional MMSE interpolation isperformed on a subframe basis in time domain and MMSE_RBWinLen RBs infrequency domain. For more information, please refer to [3].

If ChEstimatorMode is MMSE_2D, SNR should be set as the signal to noise ratio in6.dB, Tmax should be set as the maximum delay spread of the channel, Fmax shouldbe set as the maximum dopper frequency, while these parameters are ignored whenChEstimatorMode is Linear. In AWGN channel, Tmax and Fmax can be set as a smallvalue, e.g. Tmax = 1e-8s, Fmax = 0.01Hz.It should be noted that if SubframeIgnored is not 0, the first SubframeIgored7.subframes read from input are ignored. The first matrix token read from Pilots wouldbe used in the SubframeIgnored-th subframe. The Coef output for the firstSubframeIgored subframes would be all '1's.See LTE_A_UL_ChEstimator (lteabasever).8.

Notes/Equations

This model is used to generate 3GPP LTE Advanced UE-specific reference signals(DM-1.RS) for antenna port p=7,p=8,or p=7,8,...,v+6. The downlink UE-specific signals(DM-RS) are based on Reference[1].Each firing, one Matrix-based token is produced at the output DMRS,2.DMRS_WithOOC, DMRS_NoOOC and DMRS_AllSeq multiple output ports. Thebuswidth of all output ports is NumOfLayers. For ith firing, the DRMSs on all transmit


195

layers in subframe#(i%10) are output on the Matrix-based output tokens.For token DMRS, the matrix vector size is equal to NumOfDMRS_SC*NumRBs,where NumOfDMRS_SC is the number of subcarriers to carrier DM-RSs persubframe. We can get the NumOfDMRS_SC by the following figure.

Mapping of UE-specific reference signals, antenna ports 7,8,9 and10(normal cyclic prefix)

Mapping of UE-specific reference signals, antenna ports 7 and8(extended cyclic prefix)The relation between NumOfDMRS_SC and NumOfLayers is shown in thefollowing table.


196

NumOfDMRS_SC NumOfLayers CyclicPrefix

12 1,2 normal

24 3,4,5,6,7,8 normal

16 1,2 extended

For token DMRS_WithOOC and DMRS_NoOOC, the pth matrix vector size isequal to the number of active DMRSs for antenna port p for the specified UE. Forantenna port p, the number of active DMRSs in one subframe is NumRBs*12 fornormal CP and NumRBs*16 for extended CP, where NumRBs is the number ofresource blocks assigned to the UE.For token DMRS_AllSeq, the matrix vector size is equal to the number of activeDMRSs over all transmit antenna ports occupied 110 RBs. For antenna port p,the number of active DMRSs in one subframe is 110*12, where 110 is maximumnumber of resource blocks.The output DM-RS ordering at all the output ports is described as follows. Thefirst output are for the DM-RSs in the first OFDM symbol of the first slot for thefirst antenna port in increasing order of resource block index, then are the DM-RSs for other antenna port in increasing order, then are the DM-RSs for theother OFDM symbols of the first slot in increasing order, then are the DM-RSsfor the second slot.

The reference-signal sequence r(m) is defined by3.

For the definition of pseudo-random sequence c(i), please refer to the LTE_ScramblerModel document. The pseudo-random sequence generator shall be initialized with

at the start of each subframe.
