FAQ's

How are reference signals transmitted in NB-IoT?

Following “3GPP TS 36.211 V13.2.0, June 2016; Physical channels and modulation” and “Rohde-Schwarz in a white paper in web link: (www.rohde-schwarz.com/appnote/ 1MA266)” the narrowband reference signal (NRS) is transmitted in all SFs which may be used for broadcast or dedicated DL transmission, no matter if data is actually transmitted or not. Depending on the transmission scheme, NRS is either transmitted on one antenna port or on two. Its values are created like the CRS in LTE, with the NCellID taken for the PCI. The NRS mapping is additionally cyclically shifted by NCellID mod 6 in the frequency range. When NRSs are transmitted on two APs, then on every resource element used for NRS on AP0, the same resource element on AP1 is set to zero and vice versa

Which are the DL and UL NB-IoT physical channels?

Following “3GPP TS 36.211 V13.2.0, June 2016; Physical channels and modulation” and “Rohde-Schwarz in a white paper in web link: (www.rohde-schwarz.com/appnote/ 1MA266)”, DL supports three physical channels ● NPBCH, the narrowband physical broadcast channel ● NPDCCH, the narrowband physical downlink control channel ● NPDSCH, the narrowband physical downlink shared channel and two physical signals ● NRS, Narrowband Reference Signal ● NPSS and NSSS, Primary and Secondary Synchronization Signals are defined. For the uplink (UL), the two physical channels ● NPUSCH, the narrowband physical uplink shared channel ● NPRACH, the narrowband physical random access channel and the ● DMRS, Demodulation Reference Signal
