Reference channel (RC ) | 'R0' (default), 'R1' , 'R2' , 'R3' , 'R4' , 'R5' , 'R6' , 'R7' , 'R8' , 'R9' , 'R10' , 'R11' , 'R12' , 'R13' , 'R14' , 'R6-27RB' , 'R12-9RB' , 'R11-45RB' , User

Reference measurement channel (RMC) number or type, as specified
in TS 36.101, Annex A.3.
To facilitate the transmission of system information blocks (SIB), normally no
user data is scheduled on subframe 5. However, 'R.31-3A' and
'R.31-4' are sustained data rate RMCs and have user data in
subframe 5. 'R.6-27RB' , 'R.12-9RB' ,
and 'R.11-45RB' are custom RMCs configured for
non-standard bandwidths that maintain the same code rate as the standardized
versions defined in TS 36.101, Annex A.3.
To define your own reference channel, select User
defined . The User-defined configuration
dialog box opens. For Configuration structure variable
name, type the name of an RC parameter structure variable in
the MATLAB® workspace. The tool expects this variable to be
present in the MATLAB base workspace. Create the basic configuration structure with
the function lteRMCDL by choosing a closely
matched RMC and modifying to meet your requirements. Use this approach to
simulate transmission modes 7–10. Specifically, when
TxScheme = 'Port5' ,
'Port7-8' , 'Port8' , or
'Port7-14' , where DM-RS based channel estimation is
required for PDSCH demodulation. In this case, the precoding matrix,
W , is randomly defined per subframe according to TS
36.101, Table 8.3.1-1, or Table 8.3.2-1. |
Duplex mode (DuplexMode ) | 'FDD' (default), 'TDD'
| Duplexing mode, specified as:
|
Transmission scheme (TxScheme ) | 'Port0' , 'TxDiversity' ,
'CDD' , 'SpatialMux' , 'MultiUser' ,
'Port5' , 'Port7-8' , 'Port8' ,
'Port7-14' .
| PDSCH transmission scheme, specified as one of the following
options.
Transmission scheme | Description |
---|
'Port0' | Single antenna port, port 0 | 'TxDiversity' | Transmit diversity | 'CDD' | Large delay cyclic delay diversity scheme | 'SpatialMux' | Closed loop spatial multiplexing | 'MultiUser' | Multi-user MIMO | 'Port5' | Single-antenna port, port 5 | 'Port7-8' | Single-antenna port, port 7, when NLayers = 1. Dual layer transmission, ports 7 and 8, when NLayers = 2. | 'Port8' | Single-antenna port, port 8 | 'Port7-14' | Up to eight layer transmission, ports 7–14 |

PDSCH Rho (dB) (Rho ) | 0 (default), Numeric scalar | PDSCH resource element power allocation, in dB |
Propagation Model (DelayProfile ) | 'Off' , 'EPA' (default), 'EVA' , 'ETU' , 'HST'
| Delay profile model. For more information, see Propagation Channel Models. |
Doppler (Hz) (DopplerFreq ) | '5' , '70' , '300' , '750'
| Maximum Doppler frequency, in Hz. |
Antenna Correlation (MIMOCorrelation ) | 'Low' , 'Medium' , 'High'
| Correlation between UE and eNodeB antennas |
No of receive antennas (NRxAnts ) | Nonnegative scalar integer | Number of receive antennas |

Simulation length (frames) | Positive scalar integer | Simulation length, in frames |
Number of HARQ processes (NHARQProcesses ) | 1, 2, 3, 4, 5, 6, 7, or 8 | Number of HARQ processes per component carrier |
Perfect channel estimator | 'Yes' , 'No'
| Channel estimator provides a perfect channel estimate
when setting is 'Yes' . For more information, see lteDLPerfectChannelEstimate . |
PMI 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. |
Simulation results | Variable name beginning with an alphabetical character
and containing alphanumeric characters. | Simulation results output variable name. When you click Generate
