3. Channel State Information Reference Signal (CSI-RS) |
|---|
Choice: On | Off
Default: On
Double-click or use the drop-down menu to turn the channel state on or off.
Range: -60.000 to 20.000 dB
Default: 0 dB
Enter a power level in dB for the channel state information reference signal. Refer to the Output Power Calculation (Downlink) for a description of how the software applies your power settings.
Choice: 1 | 2 | 4 | 8
Default: 1
Double-click or use the drop-down menu to select the number of antenna ports for CSI-RS signals that is less than or equal to the total number of antennas.
The combination of the number of CSI-RS antenna ports and the total number of antennas determines the resource elements that are reserved for reference signals as described in .
If the Total Number of Antennas parameter is changed, Auto is selected, and the software sets the number of CRS antenna ports equal to the total number of antennas.
Refer to 3GPP TS36.211 and 36.213.
Choice: Port 15 | Ports 15 to 16 | Ports 15 to 18 | Ports 15 to 22
Default: Port 15
This is a read only parameter set by the Number of CSI-RS Antenna Ports. Available port selections depend on the number of CSI-RS antenna ports selected. For more detail, refer to 3GPP TS 36.211 and 36.213.

See 3GPP TS 36.211 and 36.213.
Range: 0 to 19 (Range is dependent on other settings as follows)
Default 0
Enter the CSI-RS subframe configuration index for the CSI-RS. This defines both the CSI-RS periodicity and the CSI-RS subframe offset in accordance with 3GPP TS 36.211 and 36.213.
The CSI-RS Configuration range is coupled to the Number of CSI-RS Antenna Ports and to the Cyclic Prefix parameter values.
The available range depends on the following settings:
|
Normal Cyclic Prefix |
Extended Cyclic Prefix |
Number of CSI-RS |
|---|---|---|
|
0 to 19 |
0 to 15 |
1 or 2 |

0 to 9 |
0 to 7 |

0 to 4 |
0 to 3 |

Refer to 3GPP TS 36.211 and 36.213.
Range: 0 to 154
Default: 0
Enter the CSI-RS Subframe Configuration index which defines both the CSI-RS Periodicity and the CSI-RS Subframe Offset parameters (Delta_CSI-RS). Subframes containing CSI reference signals shall satisfy:
Refer to TS 36.211 and 36.213.
This is read only parameter automatically set by the CSI-RS Subframe Configuration (I_CSI-RS).
This is coupled to CSI-RS Subframe Configuration (I_CSI-RS).
Subframes containing CSI reference signals shall satisfy:
I_CSI-RS = 0 to 4 , T_CSI-RS = 5
I_CSI-RS = 5 to 14, T_CSI-RS = 10
I_CSI-RS = 15 to 34, T_CSI-RS = 20
I_CSI-RS = 35 to 74, T_CSI-RS = 40
I_CSI-RS = 75 to 154, T_CSI-RS = 80
Refer to TS 36.211 and 36.213.
Range: 0 to 79 (subframe(s))
Default: 0 (subframe)
This is read only parameter automatically set by the CSI-RS Subframe Configuration (I_CSI-RS). Refer to 3GPP TS 36.211 and to 36.213.
This is coupled to CSI-RS Subframe Configuration (I_CSI-RS).
Subframes containing CSI reference signals shall satisfy:
I_CSI-RS = 0 to 4 , Delta_CSI-RS = I_CSI-RS
I_CSI-RS = 5 to 14, Delta_CSI-RS = I_CSI-RS - 5
I_CSI-RS = 15 to 34, Delta_CSI-RS = I_CSI-RS -15
I_CSI-RS = 35 to 74, Delta_CSI-RS = I_CSI-RS -35
I_CSI-RS = 75 to 154, Delta_CSI-RS = I_CSI-RS -75
