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.

This section defines the LTE/LTE-Advanced FDD DPCCH/DPDCH's buttons. The Restore Default Settings button is available in all of the LTE FDDn Uplink's tree nodes.
|
|
Restores all of the LTE/LTE-Advanced FDD channel's parameters to their default conditions. |
Choice: Off | On
Default: On
Double-click or use the drop-down menu to select the state for the PUSCH.
Range: -60 to 20 dB
Default: 0 dB
Enter a power level in dB for the selected channel relative to the carrier power.
Range: 0 to 65535
Default: 0
Enter a value for the Radio Network Temporary Identifier (RNTI). See 3GPP TS 36.211.
Choice: Off | Group Hopping | Sequence Hopping
Default: Off
Double-click or use the drop-down menu to select the hopping type. This parameter is used when the Parameter Calculation mode is set to Auto.
Group hopping is composed of a group hopping pattern and a sequence-shift pattern. There are 17 different hopping patterns and 30 different sequence-shift patterns. Sequence hopping , hopping between the two sequences within a sequence group, can be applied for resource allocation larger than 5 RBs. See 3GPP TS 36.211 for more information on hopping types.
Choice: Auto | Manual
Default: Manual
Enter the mode of the PUSCH parameter calculation.
|
Auto |
The software calculates the DMRS hopping parameters using: DMRS pattern is generated by using Group/Sequence Hopping, Delta SS, nDMRS(1) and nDMRS(2). Refer to DMRS Slot Settings. |
|
Manual |
This choice allows you to enter the DMRS hopping parameters: DMRS pattern is calculated by using DMRS Sequence Index, DMRS Group, Index and DMRS Cyclic Shift slot by slot |
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 available values are calculated by the formula 2^l * 3^m * 5^n. The maximum value is depend on the current System Bandwidth and Occupied Resource Block Offset. Refer to 3GPP TS 36.211 section 5.3, TS 36.101, Table 5.6-1 for more details.
Range: 0 to 5 (1.4MHz BW), 0 to 14 (3MHz BW), 0 to 24 (5MHz BW), 0 to 49 (10MHz BW), 0 to 74 (15MHz BW), 0 to 99 (20MHz BW)
Default: 0
Enter the number of resource blocks by which to offset the transmission of this UE.
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.
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.
Range:0 to 29
Default: 0
Enter a value to calculate the sequence-shift pattern for PUSCH DMRS.This value is used when the Parameter Calculation mode is set to Auto. Refer to 3GPP TS 36.211 for more details.
Choice: 0 | 2 | 3 | 4 | 6 | 8 | 9 | 10
Default: 0
Enter a value to calculate the cyclic shift alpha for the PUSCH DMRS data pattern. This value is used when the Parameter Calculation mode is set to Auto. Refer to 3GPP TS 36.211 for more details.
Choice: 0 | 2 | 3 | 4 | 6 | 8 | 9 | 10
Default: 0
Enter a value to calculate the cyclic shift alpha for the PUSCH DMRS data pattern.This value is used when the Parameter Calculation mode is set to Auto to calculate Refer to 3GPP TS 36.211 for more details.
