1. Cell Parameters

State

Double-click or use the drop-down menu to turn the uplink transmission off or on.

Antenna Port

Displays the antenna port number.

Total number of Antennas

Displays the total number of antennas.

PUSCH DFT Swap

Choice: Off | On

Default: Off

Double-click or use the drop-down menu to turn PUSCH DFT Swap on or off.

PUSCH DFT Swap influences how data is mapped to resource elements in the physical uplink shared channel after discrete Fourier transform is performed. PUSCH DFT Swap can be turned on or off to provide two different interpretations of how data should be mapped to resource elements in PUSCH channels.

2. Sounding Reference

State

Choice: Off | On

Default: Off

Double-click or use the drop-down menu to turn the sounding reference signal on or off.

Power

Range: -60.000 to 20.000 dB

Default: 0.000 dB

Set the power of the sounding reference signal in dB.

Group/Sequence Hopping

Choice: Off | Group Hopping | Sequence Hopping

Default: Off

Double-click or use the drop-down menu to select the hopping type.. (See 3GPP TS 36.211)

Subframe Configuration

Choice: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13

Default: 0

Double-click or use the drop-down menu to select subframe configuration of sounding reference signal.

Maximum UpPTS

Choice: Off | On

Default: Off

Double-click or use the drop-down menu to turn the sounding reference signal Max UpPTS state on or off.

Number of Format 4 PRACH

Set the Number of Format 4 PRACH burst allocated in the special subframe, you can set this value to 0, 1, 2, 3, 4 ,5 for each special subframe as described in 3GPP TS 36.211.

Cyclic Shift (nSRS_CS)

Choice: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7

Default: 0

Double-click or use the drop-down menu to select the value which is used to calculate the cyclic shift for sounding reference signal.

Bandwidth Configuration (C_SRS)

Choice: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7

Default: 7

Double-click or use the drop-down menu to select the bandwidth configuration for sounding reference signal.

Bandwidth (B_SRS)

Choice: 0 | 1 | 2 | 3

Default: 0

Double-click or use the drop-down menu to select the Bandwidth indicator for sounding reference signal.

SRS Bandwidth (B_SRS), SRS Hopping Bandwidth (b_hop), and Frequency Hopping are related as follows:

Frequency Hopping On: SRS Hopping Bandwidth (b_hop) < SRS Bandwidth (B_SRS)

Frequency Hopping Off: SRS Hopping Bandwidth (b_hop) >= SRS Bandwidth (B_SRS)

Transmission Comb (kTC)

Choice: 0 | 1

Default: 0

Double-click or use the drop-down menu to select the offset value which is related with the transmission comb for sounding reference signal.

Hopping Bandwidth (b_hop)

Range: Choice: 0 | 1 | 2 | 3

Default: 3

Double-click or use the drop-down menu to select the frequency hopping bandwidth of sounding reference signal.

SRS Bandwidth (B_SRS), SRS Hopping Bandwidth (b_hop), and Frequency Hopping are related as follows:

Frequency Hopping On: SRS Hopping Bandwidth (b_hop) < SRS Bandwidth (B_SRS)

Frequency Hopping Off: SRS Hopping Bandwidth (b_hop) >= SRS Bandwidth (B_SRS)

Frequency Domain Position (nRRC)

Range: 0 to Int32

Default: 0

Enter the frequency domain position RRC value which is from the upper layer for sounding reference signal.

Configuration Index (I_SRS)

Choice: 0 to 644

Default: 0

Enter the configuration Index for sounding reference signal.

Periodicity (T srs)

This is read only parameter and the value is automatically selected by the software. Refer 36.213V8.5.0 Table 8.2-1 (See 3GPP).

Subframe Offset Configuration (T offset)

This is read only parameter and the value is automatically selected by the software. Refer 36.213V8.5.0 Table 8.2-1 (See 3GPP).

Frequency Hopping

This is read only parameter and the value is automatically selected by the software.

SRS Bandwidth (B_SRS), SRS Hopping Bandwidth (b_hop), and Frequency Hopping are related as follows:
