Syntax

rmccfgout = lteRMCDL(rc)
rmccfgout = lteRMCDL(rc,duplexmode)
rmccfgout = lteRMCDL(rc,duplexmode,totsubframes)
rmccfgout = lteRMCDL(rmccfg,ncodewords)

Description

rmccfgout = lteRMCDL(rc) returns configuration structure rmccfgout for reference channel rc. This structure uses a channel-specific default configuration. The structure contains the configuration parameters required to generate a given reference channel waveform using the reference measurement channel (RMC) generator tool, lteRMCDLTool. The field names and default values comply with the definition found in TS 36.101 [1], Annex A.3.

example

rmccfgout = lteRMCDL(rc,duplexmode) specifies duplexmode, the duplexing mode.

example

rmccfgout = lteRMCDL(rc,duplexmode,totsubframes) specifies totsubframes, total number of subframes to generate.

rmccfgout = lteRMCDL(rmccfg,ncodewords) returns a fully configured structure for the reference channel partially, or wholly, defined by input structure rmccfg. You can specify the number of PDSCH codewords to modulate in the ncodewords input.

Create a configuration structure for reference measurement channel R.44 as specified in TS 36.101.

rc = 'R.44';

rmcOut = lteRMCDL(rc);

For this RMC, the size of the resource allocation varies per subframe. Evidence of this is seen by viewing the PRBSet and observing that the length of resource allocation vectors in the PRBSet cell array vary per subframe.

Create a new customized parameter set by overriding selected values of an existing preset RMC. To define a single codeword full-band 10MHz PDSCH using 4 CRS port spatial multiplexing and 64QAM modulation, begin by initializing an RMC configuration structure to R.13. Looking at TS 36.101, Table A.3.1.1-1, see the RMC R.13 matches desired configuration except the default QPSK modulation must be adjusted.

See footnote.

  1. CFI is equal to the number of symbols allocated to:

    • (PDCCH - 1) for NDLRB < 10

    • PDCCH for NDLRB ≥ 10

    For the RMCs, the number of symbols allocated to PDCCH varies with channel bandwidth setting,

    • Two symbols for 20 MHz, 15 MHz, and 10 MHz

    • Three symbols for 5 MHz and 3 MHz

    • Four symbols for 1.4 MHz

    • In the TDD mode, only two OFDM symbols are allocated to PDCCH in special subframes irrespective of the channel bandwidth. Therefore, the CFI value varies per subframe for the 5 MHz, 3 MHz, and 1.4 MHz channel bandwidths. Specifically, for bandwidths where PDCCH symbol allocation is not two in other subframes.

  2. The PDCCH OCNG fills the unused PDCCH resource elements with QPSK symbols using either single port or transmit diversity depending on the number of cell RS ports.

  3. All supported RMCs use TDDConfig 1 by default. When you specify a value different then the default, the full parameter set is configured according to the following rules.

    • Preserve subframe 0 (downlink) for all TDDConfig — The values of the parameters in subframe 0 of TDDConfig 1 is applied in all other TDDConfig.

    • Preserve special subframe behavior — The values of the parameters in special subframes of TDDConfig 1 is applied in all other TDDConfig.

    • Preserve subframe 5 (downlink) for all TDDConfig — The values of the parameters in subframe 5 of TDDConfig 1 is applied to all other TDDConfig. For all RMCs currently supported, subframe 5 is treated separately from other subframes. According to TS 36.101 Section A.3.1, “Unless otherwise stated, no user data is scheduled on subframes 5 in order to facilitate the transmission of system information blocks (SIB).” Hence the RC value, if present, determines the behavior of subframe 5. This means that subframe 5 is not transmitted for other RMCs, with the exception of sustained data rate RMCs R.31-3A and R.31-4.

    • All other downlink subframes use the same settings as subframe 9.

Modulation'QPSK', '16QAM', '64QAM', '256QAM', '1024QAM'

Modulation type, specified as a character vector, cell array of character vectors, or string array. If blocks, each cell is associated with a transport block.

NLayers

Integer from 1 to 8

Number of transmission layers.

NTxAnts

Nonnegative scalar integer

Number of transmission antenna ports. This argument is present only for UE-specific demodulation reference symbols.

Note

NTxAnts is provided by lteRMCDL for information only.

Rho

0 (default), numeric scalar

PDSCH resource element power allocation, in dB

RNTI

0 (default), scalar integer

Radio network temporary identifier (RNTI) value (16 bits)

RVSeq

Integer vector (0,1,2,3), specified as a one or two row matrix (for one or two codewords)

Redundancy version (RV) indicator used by all HARQ processes, returned as a numeric matrix. RVSeq is a one- or two-row matrix for one or two codewords, respectively. The number of columns in RVSeq equals the number of transmissions of the transport blocks associated with a HARQ process. The RV sequence specified in each column is applied to the transmission of the transport blocks. If RVSeq is a scalar (or column vector in the case of two codewords), then there is a single initial transmission of each block with no retransmissions. If RVSeq is a row vector in a two-codeword transmission, then the same RV sequence is applied to both codewords.

See footnote.

RV

Integer vector (0,1,2,3). A one or two column matrix (for one or two codewords).

Specifies the redundancy version for one or two codewords used in the initial subframe number, NSubframe. This parameter field is only for informational purposes and is read-only.

Number of HARQ processes per component carrier

NTurboDecits

5 (default), nonnegative scalar integer

Number of turbo decoder iteration cycles

PRBSetInteger-valued column vector, two-column matrix, cell array

Zero-based physical resource block (PRB) indices corresponding to the slot-wise resource allocations for this PDSCH. The function returns this field as one of these values.

  • An integer-valued column vector. The resource allocation is the same in both slots of the subframe.

  • A two-column matrix or two-element cell array, which specifies different PRBs for each slot in a subframe.

  • A cell array of length 10 (corresponding to a frame, if the allocated physical resource blocks vary across subframes).

This field varies per subframe for these RMCs: 'R.25' (with TDD), 'R.26' (with TDD), 'R.27' (with TDD), 'R.43' (with FDD), 'R.44', 'R.45', 'R.48', 'R.50', 'R.51', 'R.68-1', and 'R.105'.

TargetCodeRate

Scalar or one or two row numeric matrix

Target code rates for one or two codewords for each subframe in a frame. Used for calculating the transport block sizes according to TS 36.101 [1], Annex A.3.1.

If both TargetCodeRate and TrBlkSizes are not provided at the input, and the RC does not have a single ratio target code rate in TS 36.101, Table A.3.1.1-1, TargetCodeRate == ActualCodeRate.

ActualCodeRate

One or two row numeric matrix

Actual code rates for one or two codewords for each subframe in a frame, calculated according to TS 36.101 [1], Annex A.3.1. The maximum actual code rate is 0.93. This parameter field is only for informational purposes and is read-only.

TrBlkSizes

One or two row numeric matrix

Transport block sizes for each subframe in a frame

See footnote.

CodedTrBlkSizes

One or two row numeric matrix

Coded transport block sizes for one or two codewords. This parameter field is for informational purposes and is read-only.

See footnote.

Downlink control information (DCI) format type of the PDCCH associated with the PDSCH. See lteDCI.

PDCCHFormat

0, 1, 2, 3

Aggregation level of PDCCH associated with PDSCH

PDCCHPower

Numeric scalar

PDCCH power in dB

CSIMode

'PUCCH 1-0', 'PUCCH 1-1', 'PUSCH 1-2', 'PUSCH 3-0', 'PUSCH 3-1'

CSI reporting mode

PMIMode

'Wideband' (default), 'Subband'

PMI reporting mode. PMIMode='Wideband' corresponds to PUSCH reporting Mode 1-2 or PUCCH reporting Mode 1-1 (PUCCH Report Type 2) and PMIMode='Subband' corresponds to PUSCH reporting Mode 3-1.

The following field is present only for TxScheme = 'SpatialMux'.
  PMISet

Integer vector with element values from 0 to 15.

Precoder matrix indication (PMI) set. It can contain either a single value, corresponding to single PMI mode, or multiple values, corresponding to multiple or subband PMI mode. The number of values depends on CellRefP, transmission layers and TxScheme. For more information about setting PMI parameters, see ltePMIInfo.

The following field is present only for TxScheme = 'Port7-8', 'Port8', or 'Port7-14'.
  NSCID

0 (default), 1

Scrambling identity (ID)

The following field is present only for UE-specific beamforming ('Port5', 'Port7-8', 'Port8', or 'Port7-14').
  W

Numeric matrix

NLayers-by-P precoding matrix, chosen according to TS 36.101 Annex B.4. P is the number of transmit antennas. The resulting precoding matrix with index zero is selected from:

  • The set defined in TS 36.211, Section 6.3.4 for 'Port5', 'Port7-8', and 'Port8' transmission schemes

  • or from the set associated with CSI reporting as defined in TS 36.213, Section 7.2.4 for the 'Port7-14' transmission scheme.

W is present only for wideband UE-specific beamforming ('Port5', 'Port7-8', 'Port8', 'Port7-14').

  1. The function returns valid TrBlkSizes and CodedTrBlkSizes set to 0 when PRBSet is empty, indicating there is no PDSCH allocation in this frame.

  2. Any parameters missing at the input are initialized based on the RC field if present or 'R.0' otherwise.

    • When the RC field is specified, the RMC specified defines the subframe scheduling.

    • If the RC field is absent or set to empty, all downlink subframes and special subframes (if TDD mode) are assumed to be scheduled.

    • TrBlkSizes and CodedTrBlkSizes are set according to the target code rate, the modulation scheme, and the allocated resources.

    • The value of RVSeq is set according to the modulation scheme.
