Open NetSim, Select Examples ->5G NR ->Max Throughput vs MCS and CQI then click on the tile in the middle panel to load the example as shown in below screenshot
Figure 4‑35: List of scenarios for the example of Max Throughput vs MCS and CQI
The following network diagram illustrates, what the NetSim UI displays when you open the example configuration file.
Figure 4‑36: Network set up for studying the Max Throughput vs MCS and CQI
Settings done in example config file:
Set grid length as 1000m from Environment setting.
Go to gNB properties à Interface (5G_RAN), set the following properties as shown below Table 4‑31.
|Physical Layer Properties|
|Numerology||Channel Bandwidth (MHz)|
Table 4‑31: gNB >Interface (5G_RAN) >Physical layer properties
- Go to Wired link properties and set the following properties as shown below Table 4‑32.
|Wired Link Properties|
|Uplink and Downlink BER||0.0000001|
Table 4‑32: Wired Link Properties
- Go to Application properties and set the following properties as shown below Table 4‑33.
Table 4‑33: Application properties
Set TX_Antenna_Count as 2 and RX_Antenna_Count as 1 in gNB properties.
Set TX_Antenna_Count as 1 and RX_Antenna_Count as 2 in UE properties.
Plots are enabled in NetSim GUI.
Run Simulation for 1.002s, after simulation completes go to metrics window and note down throughput and delay value from application metrics.
For this Scenario set MCS Table as QAM64LOWSE and CQI Table as TABLE3 and note down throughput.
Go Back to the Scenario and set MCS Table as QAM64 and CQI Table as TABLE1 and note down throughput.
Go Back to the Scenario and set MCS Table as QAM256 and CQI Table as TABLE2 and note down throughput.
|MCS Table||CQI Table||Throughput (Mbps)|
