10.2.1.1 Physical channels

A downlink narrowband physical channel corresponds to a set of resource elements carrying information originating from higher layers and is the interface defined between TS 36.212 [3] and the present document TS 36.211.

The following downlink physical channels are defined:

– Narrowband Physical Downlink Shared Channel, NPDSCH

– Narrowband Physical Broadcast Channel, NPBCH

– Narrowband Physical Downlink Control Channel, NPDCCH

10.2.1.2 Physical signals

A downlink narrowband physical signal corresponds to a set of resource elements used by the physical layer but does not carry information originating from higher layers. The following downlink physical signals are defined:

– Narrowband reference signal, NRS

– Narrowband synchronization signal

– Narrowband positioning reference signal, NPRS

– Narrowband wake up signal, NWUS
