PUSCH

The software controls PUCCH transmission based on the HARQ packet number. The Demodulation Reference signals (DMRS) for PUSCH can be automatically configured or manually configured for each slot using the parameter settings in the DMRS Slot Settings tab.

When using multiple instruments as shown in the tree view, inaccurate test data may occur if a combination of the GUI and SCPI is used to set or modify the instrument and test parameters. The software will not reflect changes made outside of the GUI even with the use of the Update from Instrument button. For all tests, use only one method to configure the settings, GUI or SCPI.

When configuring multiple instruments with SCPI instead of using the GUI, the commands must be executed for each instrument.

When using multiple instruments as shown in the tree view, after clicking the State On button, all settings for this window gray out and cannot be changed. To change the settings, first click the State Off button.

Buttons

This button indicates that the current real-time settings have been applied to the instrument—no action is required. This button is not available when the Apply Needed button is active. When using multiple instruments as shown in the tree view, this button is not displayed.

This button displays in place of the Settings Current button. It indicates that the instrument settings are not currrent and need to be updated with the new software settings. Click this button to update the insturment's settings. This button shows in all windows regardless of where the change was made. When using multiple instruments as shown in the tree view, this button is not displayed.

Parameter Calculation Mode

Choice: Auto | Manual

Default: Auto

Coupling: This setting is inactive and set to AUTO when using multiple instruments as shown in the tree view.

Enter the mode of the PUSCH parameter calculation.

Auto	The software calculates the DMRS hopping parameters using: nDMRS(1), nDMRS(2), and Delta SS.The Hopping Type parameter is active in this mode.
Manual	This choice allows you to enter the DMRS hopping parameters; Sequence Index, Group Index, and Cyclic Shift for slot 0 to 19 in the DMRS Parameter Settings tab. The pattern for the twenty slots is repeated during data generation.

2. Transmission Settings

Occupied Resource Block Size

Range: 1 to Maximum resource blocks determined by the Transmission Bandwidth selection.

Default: 6 (1.4MHz BW), 15 (3MHz BW), 25 (5MHz BW), 50 (10MHz BW), 75 (15MHz BW), 100 (20MHz BW)

Enter an integer between 1 and the maximum number of resource blocks. The maximum value depends on the current transmission bandwidth.

3. Demodulation Reference Signal Settings

The DMRS is used for synchronization and uplink channel estimation and is allocated with PUSCH on all subframes. The DMRS for PUSCH are transmitted in the fourth symbol, (third symbol for extended CP) in a PUSCH slot and the RS sequence length equals the number of allocated subcarriers (12). The DMRS uses the same resource block size and resource block offset that is used by PUSCH; however, the demodulation RS power can be set independently.

DMRS Power

Range:-60 to 20 dB

Default: 0 dB

Enter a power level in dB for the power of demodulation reference. The power of the demodulation RS can be set independently from PUSCH power.
