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:

  1. Set grid length as 1000m from Environment setting.

  2. Go to gNB properties à Interface (5G_RAN), set the following properties as shown below Table 4‑31.

Properties
Physical Layer Properties
Frequency Range FR2
CA_TYPE INTER_BAND_NONCONTIGUOUS_CA
CA_Configuration CA_n261(2Q) _n261A
Numerology Channel Bandwidth (MHz)
CA1 2 100
CA2 2 100
CA3 2 100
CA4 2 100
CA5 2 100
CA6 2 100
CA7 2 100
CA8 2 100
Pathloss Model None

  1. Go to Wired link properties and set the following properties as shown below Table 4‑32.
Wired Link Properties
Uplink_Speed (Mbps) 100000
Downlink_Speed (Mbps) 100000
Uplink and Downlink BER 0.0000001

  1. Go to Application properties and set the following properties as shown below Table 4‑33.
Application Properties
Source_Id 10
Destination_Id 8
Transport Protocol UDP
Start_Time 1s
Packet_Size 1460Bytes
Inter_Arrival_time 1μs
Generation Rate 10000Mbps

Table 4‑33: Application properties

  1. Set TX_Antenna_Count as 2 and RX_Antenna_Count as 1 in gNB properties.

  2. Set TX_Antenna_Count as 1 and RX_Antenna_Count as 2 in UE properties.

  3. Plots are enabled in NetSim GUI.

  4. 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.

Result:

MCS Table CQI Table Throughput (Mbps)
QAM64LOWSE TABLE3 1763.68
QAM64 TABLE1 2225.04
QAM256 TABLE2 2902.48
