When DC Punctured is enabled, the DC subcarrier is excluded from the generated signal.
In an orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) signal, the subcarrier whose frequency would be equal to the RF center frequency of the station is referred to as the DC subcarrier.
For uplink carrier with Transform Precoding enabled for UL-SCH, DC Punctured is forced to Off.

Enables or disables the baseband filter.
The filter is applied to each numerology of this carrier. It is a low-pass or band-pass FIR filter with hamming window. The central frequency and bandwidth of this filter depend on the resource allocation of each numerology.
Taps: 1024
Band margin: 1 RB for each side
Only available when the carrier type is a downlink or uplink. Not applicable for PRACH.
It is recommended to enable baseband filter to achieve a balance between ACPR and EVM performance.

Sets the component carrier's frequency range and bandwidth.
When bandwidth changes, the MaxRB (for single numerology mode) or N_grid_size(for multiple numerologies mode) is automatically updated based on the table in TS38.101-1 for FR1 and TS38.101-2 for FR2.

MU1 = 30 kHz
MU2Ncp = 60 kHz Normal CP
MU3 = 120 kHz
Sets the numerology for the component carrier in single numerology mode. Setting this value reverts the Max RB for valid numerologies to default and resets the user-defined values to those defined in 3GPP specification 38.104 table 5.3.2-1 and 5.3.2-2. This value also determines the set of valid numerology that can be used by a resource allocation within the carrier.
This parameter is only visible in single numerology mode, and it will determine the numerology of all the channels/BWPs in this carrier.
The 15 kHz/30 kHz subcarrier spacing can be used only in frequency range 1 (FR1); 120 kHz/240 kHz subcarrier spacing can be used only in frequency range 2 (FR2); 60 kHz subcarrier spacing can be used in either FR1 or FR2.
Cyclic Prefix (CP) length specifies the symbols per slot. For normal, each slot occupies 14 symbols and for extended each slot occupies 12 symbols. Extended CP is used for subcarrier spacing (SCS) of 60 kHz only. Normal CP length = 7.03125% the length of the symbol and extended CP length = 25% of the length of a signal.

Sets the maximum number of RB for current numerology of the carrier in Single Numerology mode. The default value is the max RB size for the numerology based on the selected Bandwidth.
This parameter is only visible in Single Numerology mode, it determines the bandwidth of current carrier, the center of carrier is assumed at the middle of whole RB range if k0 is 0, and the N_grid_start for selected numerology is 0.
