nrPDSCHMCSTables

PDSCH MCS lookup tables

Since R2024a

Description

The nrPDSCHMCSTables object contains the physical downlink shared channel (PDSCH) modulation and coding scheme (MCS) tables, as defined in TS 38.214 Section 5.1.3.1 [1]. The object stores each of the four tables as a read-only property. The columns in each table are MCSIndex, Qm, TargetCodeRate, SpectralEfficiency, as defined in the specification, and Modulation, which denotes the modulation type. The TargetCodeRate column contains the fractional target code rates that the object obtains by dividing the target code rates from the specification by 1024. A table value of NaN corresponds to the "reserved" value from [1].

Creation

Syntax

pdschmcsTables = nrPDSCHMCSTables

Description

pdschmcsTables = nrPDSCHMCSTables creates an object that contains PDSCH MCS tables.

Data Types: table

QAM64LowSETable — MCS index table 3

Read-only: table

This property is read-only.

MCS index table 3, returned as a table. This property corresponds to Table 5.1.3.1-3 in TS 38.214.

Data Types: table

QAM1024Table — MCS index table 4

Read-only: table

This property is read-only.

MCS index table 4, returned as a table. This property corresponds to Table 5.1.3.1-4 in TS 38.214.

Examples

Get Modulation Type for MCS Index

Create an nrPDSCHMCSTables object.

pdschmcsTables = nrPDSCHMCSTables;

Specify an MCS index of 8. Get the modulation type that corresponds to your MCS index.

iMCS = 8;
table64QAM = pdschmcsTables.QAM64Table;
modType = table64QAM.Modulation(table64QAM.MCSIndex == iMCS);
disp(modType)

    {'QPSK'}
