Downlink FRC Configuration

Bandwidth

Choices:

Downlink: Based on the Table 5.3.2-1 and 5.3.2-2 in 38.104

Uplink: Based on the Table 5.3.2-1 in 38.101-1 and 38.101-2

Selects the bandwidth configuration for the carrier.

Numerology

Selects the numerology of the configuration. The choices are related to the selected bandwidth.

Duplex Type

Choices: TDD | FDD

Selects the duplex type.

When TDD is selected, several TDD parameters appear below. These TDD parameters are reset to default values whenever numerology changes or FR changes. (The default values are different for each numerology.)

Transmission Periodicity

Sets the periodicity of DL-UL pattern. The choices are related to numerology.

Read-only.

Number of Downlink Slots

Sets the number of consecutive full DL slots at the beginning of each DL-UL pattern. The range is related to the numerology and slot configuration period.

Read-only.

Number of Downlink Symbols

Range: 0 ~ 14 for Normal CP; 0 ~ 12 for Extended CP

Sets the number of consecutive DL symbols in the beginning of the slot following the last full DL slot.

Read-only.

Number of Uplink Slots

Sets the number of consecutive full UL slots at the end of each DL-UL pattern. The range is related to the numerology and slot configuration period.

Read-only.

Number of Uplink Symbols

Range: 0 ~ 14 for Normal CP; 0 ~ 12 for Extended CP

Sets the number of consecutive UL symbols in the end of the slot preceding the first full UL slot.

Read-only.

Number of Special Slots

Displays the number of special slots.

Read-only.

TDD Slot Allocation

Displays the TDD slot allocation for one period.

Read-only.

FRC Type

Choices: QPSK | 64QAM | 256QAM

Default: QPSK

Selects the downlink FRC type.

OFDMA Channel Noise Generator

Choices: On | Off

Default: Off

Enable or disable OFDMA channel noise generator when setting downlink FRC.

Phase Compensation

For waveform playback mode:

Choices: Auto | Auto (Real-time) | Manual | Manual (Real-time) | Off

For real-time uplink mode:

Choices: Auto | Manual | Off

Default: Auto

Sets the phase compensation mode on baseband signal before upconversion.

Auto | Auto (Real-time): Use the RF frequency from the instrument node.

Manual | Manual (Real-time): Enter the RF frequency manually.

Off: Disable phase compensation on baseband signal.

(Real-time) means the phase compensation is done using FPGA inside the instrument.
