LTE FDD
For Waveform Playback (ARB) capability.
This topic describes the settings of the Cell Parameters node.
Total Number of Resource Blocks
Total Number of Occupied Subcarriers
Number of Subcarriers for Resource Block
Number of Symbols for Resource Block
nDMRS-CSH-Identity (N_csh_DMRS_ID)
This setting specifies Cell ID.
The software sets the values in the Physical Layer Cell ID Group and Physical Layer Cell ID Sector cells based on the Cell ID entry. Cell ID = (3 x Physical Cell ID Group) + Physical Cell ID Sector.
See 3GPP TS 36.211 for more information.
Note Frequency Offset and Cell ID are always editable, even if Auto Carrier Aggregation Configuration is on.
In the case (1) or (2), auto configuration is done for Frequency Offset and Cell ID.
(1) When any action "Add CC" or "Delete CC" or "Copy CC" or Change System BW is done and Auto Carrier Aggregation Configuration parameter is On.
(2) When Auto Carrier Aggregation Configuration parameter is changed to On from Off.
Auto configuration sets Cell ID same as Component Carrier Ind–x - 1.
If Auto Carrier Aggregation Configuration is set to off, auto configuration does not work.

In the case that Number of HARQ Processes is 3 or 4 (TTI Bundling is on), Total Number of Antennas is set to '1 Antenna' as read-only.
When multiple antennas are configured, this setting is read-only.

This setting specifies the system bandwidth and number of Resource Blocks (RB).
When the system bandwidth is changed, the software automatically adjusts the value in the Total number of Resource Blocks cell, the Total number of Occupied Subcarriers cell and so on.
Note: The resource blocks and some parameters are reconfigured by changing the System Bandwidth parameter.
In the case (1) or (2), auto configuration is done for Frequency Offset and Cell ID.
(1) When any action, Add Carrier, Delete Carrier, or Change System BW is executed and Auto Carrier Aggregation Configuration is on.
(2) When Auto Carrier Aggregation Configuration is changed to on from off.
Auto configuration sets the Cell ID to the same value as Component Carrier Index.
If Auto Carrier Aggregation Configuration is set to off, auto configuration does not work.
System Bandwidth is automatically set to 10 MHz or 20 MHz when Resource Allocation Type 3 is changed to on.
Resource Allocation Type 3 is automatically set to off when System Bandwidth is changed to a value other than 10 MHz or 20 MHz.
