6.1.3 NB-IoT Test Model

36.1413GPPBase Station (BS) conformance testingEvolved Universal Terrestrial Radio Access (E-UTRA)Release 17TS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

The set-up of physical channels for transmitter tests shall be according to the NB-IoT Test Model (N-TM) below.

The following general parameters are used:

– The test models are defined for a single antenna port (using p = 1000);

– Duration is 10 subframes (10 ms)

– Normal CP

The following physical channel parameters are used:

– The ratio of synchronisation signal EPRE and NRS EPRE is 0 dB

– NPDCCH format 1

For NB-IoT TDD, test models are derived based on the uplink/downlink configuration 1 and special subframe configuration 7 defined in TS 36.211 [12], i.e. as showing in the table 6.1.3-1. Number of frames for the test models is 2.
