LTE FDD
For Waveform Playback (ARB) capability.
This topic describes the settings of the Cell Parameters node. This node is displayed when the carrier is Uplink NB-IoT.
Number of Symbols in Slot (N-UL_symb)
Sets a value for Narrowband Cell ID.
Range: 0 to 503
Default: The default value depends on the Operation Mode as described below.
When Auto Carrier Aggregation Configuration is On, the default value for Narrowband Cell ID is same as CC index, otherwise it is 0.
The software sets the values in the Physical Layer Narrowband Cell ID Group and Physical Layer Narrowband Cell ID Sector cells based on Narrowband Cell ID. Narrowband Cell ID = (3 x Physical Narrowband Cell ID Group) + Physical Narrowband Cell ID Sector.
See 3GPP TS 36.211 10.2.6 for more information.
When any action, Add CC, Delete CC, or Change System BW is executed and Auto Carrier Aggregation Configuration is on, Frequency Offset and Narrowband Cell ID are automatically configured.
Auto configuration sets Narrowband Cell ID to the same value as Component Carrier Index.
If Auto Carrier Aggregation Configuration is set to off, auto configuration does not work.
