LTE TDD
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
This setting specifies Cell ID.
See 3GPP TS 36.211 for more information.
Notes Frequency Offset and Cell ID are always editable, even if Auto Carrier Aggregation Configuration on.
In the case (1) or (2), auto configuration is done for Frequency Offset, Cell ID, Uplink Downlink Configuration, Special Subframe Configuration and Cyclic Prefix.
(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 Index, and the parameters (Uplink downlink Configuration, Special Subframe Configuration and Cyclic Prefix) on the secondary cells same value of the primary cell as read-only parameter.
If Auto Carrier Aggregation Configuration is set to off, auto configuration does not work.

Sets 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 Sub-carriers cell and so on.
Notes: 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, Cell ID, Uplink Downlink Configuration, Special Subframe Configuration and Cyclic Prefix.
(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, and the parameters (Uplink downlink Configuration, Special Subframe Configuration and Cyclic Prefix) on the secondary cells to the same value of the primary cell and read-only.
Auto configuration sets the Cell ID to the same value as Component Carrier Index.
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.

Sets Normal or Extended cyclic prefix. The software sets Number of Symbols for Resource Block based on the cyclic prefix selection.
When the corresponding Component Carrier is set to secondary cell and Auto Carrier Aggregation Configuration parameter is set to on, Cyclic Prefix is set to the same value as the primary cell value and read-only.
Cyclic Prefix is automatically set to Normal when Resource Allocation Type 3 is changed to on.
Resource Allocation Type 3 is automatically set to off when Cyclic Prefix is changed to Extended.
