Questions for NB-IoT NPDSCH Block Error Rate Simulation and Waveform Generation Example

In NB-IoT NPDSCH Block Error Rate Simulation and Waveform Generation example,

NPDSCH.Modulation = 'QPSK'; % Modulation scheme (must be QPSK)

1) Can I use with other modulation type? Or Does current NB-IOT only supports QPSK only?

2) How to get number of NPDSCH.TrBlkSize? In example, NPDSCH.TrBlkSize = 208. Please advise me reference document for reading.

Thanks.

The NB-IoT specific NDPSCH channel is only defined for QPSK (TS 36.211 section 10.2.3.2).

The signallable range of transport block sizes (when the NPDSCH is not carrying SIB1-NB) are given by TS 36.214 table 16.4.1.5.1-1. Note that it is dependent on the ISF that's in use.

There are more 3GPP LTE standard references in the example which cover the NB-IoT PHY processing and procedures.
