Examples
Generate LTE DL RMC R.31-4
Generate a time domain signal and a 3-dimensional array of the resource elements for R.31-4 FDD as specified in TS 36.101 Annex A.3.9.1-1. R.31-4 FDD is 20MHz, 64QAM, variable code rate and has user data scheduled in subframe 5.
[txWaveform,txGrid,rmcCfgOut] = lteRMCDLTool('R.31-4',{[1;0] [1;0]});
Generate RMC R.3 with SIB
This example shows use of lteRMCDLTool
to generate a tx waveform with SIB transmission enabled using DCIFormat1A and localized allocation.
Specify desired RMC, initialize configuration structure and define txData
. Generate txGrid
and plot it.
rc = 'R.3';
rmc = lteRMCDL(rc);
txData = [1;0;0;1];
[~,txGrid,~] = lteRMCDLTool(rmc, txData);
mesh(abs(txGrid))
view(2)
To insert SIB1 message into the output waveform, initialize SIB
substructure, enable SIB transmission, adjust other defaults, and regenerate txGrid. Plot txGrid
to illustrate the presence of SIB1 message in subframe 5
rmc.SIB.Enable = 'On'; rmc.SIB.DCIFormat = 'Format1A'; rmc.SIB.AllocationType = 0; rmc.SIB.VRBStart = 8; rmc.SIB.VRBLength = 8; rmc.SIB.Data = randi([0 1],144,1); [txWaveform,txGrid,rmcCfgOut] = lteRMCDLTool(rmc, txData); figure mesh(abs(txGrid)) view(2)
Generate LTE DL RMC R.12 With 16QAM Modulation
Generate a time domain waveform, and a 3D array of the resource elements for RMC R.12 as specified in TS 36.101. Modify the standard R.12 RMC to use 16QAM modulation scheme instead of the default QPSK.
Create an RMC setting structure specifying R.12 for RC
and 16QAM for Modulation
.
rmc.RC = 'R.12'; rmc.PDSCH.Modulation = '16QAM';
Generate the tx waveform, RE grid and also output the RMC configuration structure.
txData = [1;0;0;1]; [txWaveform, txGrid, rmcCfgOut] = lteRMCDLTool(rmc, txData);

Data Types: char
| string
trdata
— Information bits
vector | cell array containing one or two vectors
Information bits, specified as a vector or cell array containing
one or two vectors of bit values. Each vector contains the information
bits stream to be coded across the duration of the generation, which
represents multiple concatenated transport blocks. If the number of
bits required across all subframes of the generation exceeds the length
of the vectors provided, the txdata
vector is looped
internally. This feature allows you to enter a short pattern, such
as [1;0;0;1]
, which is repeated as the input to
the transport coding. In each subframe of generation, the number of
data bits taken from this stream comes from the elements of the rmccfgout
.PDSCH.TrBlkSizes
matrix.
When the trdata
input contains empty vectors,
there is no transport data. The transmission of PDSCH and its corresponding
PDCCH are skipped in the waveform
when the trdata
contains
empty vectors. The other physical channels and signals are transmitted
as normal in generated waveform
.
Example: [1;0;0;1]

— Reference channel configuration
structure
Reference channel configuration, specified as a structure. Create a reference configuration
structure with default parameters by using the lteRMCDL

To generate the waveform
output in alignment with your simulation
requirements, modify the output of the lteRMCDL
function
. To add SIB1 messages and the associated PDSCH and
