This section allows you to configure the top level modulation parameters for each carrier.
Cell ID: Specifies the physical layer cell identity. The range is 0 to 1007. The default value is 0.
Channel Bandwidth: Specifies the overall bandwidth, comprised of bandwidth parts. Valid values range from 5 MHz to 400 MHz.
Time Domain Windowing Duration (% Of CP): Time-domain windowing is not mandatory in the NR standard. The window function is employed to reduce out-of-band spectrum emissions.
The windowing duration specifies the time interval of the time-domain windowing. By default, it is set to 20 percent of the cyclic prefix length. Increasing the duration increases the spectrum roll-off at the cost of a decreased delay spread tolerance.
Oversampling Factor: Specifies the relation between the final output sample rate and the native sample rate.
For example, an oversampling factor of 4 means that the final output sample rate will be 4 times the symbol rate.
Reference Grid Alignment Mode: Specifies whether the component carrier is aligned to a reference grid of a frequency range. In Auto mode, the reference grid is selected from the largest configured subcarrier spacing in a bandwidth part. In Manual mode, you specifies the subcarrier spacing of the reference grid manually.
Reference Grid Subcarrier Spacing Mode: Specifies the subcarrier spacing for reference grid when Reference Grid Alignment Mode is set to Manual.
Reference Grid Start: Specifies the resource block offset of the reference grid relative to the Ref Pt. A when Reference Grid Alignment Mode is set to Manual.
Number of BWP Configurations: Specifies the number of configured bandwidth parts (BWP) in a carrier. Currently only a single BWP can be configured.
