I am trying to maximize the throughput of a 5G network scenario. What should be the CA settings and DL:UL ratio for achieving Max rate?
I would think you can choose the configuration that provides maximum (combined) channel bandwidth.
The ratio can be set depending on whether your network has more DL traffic or more UL traffic, or for more precision the ratio of DL to UL traffic.
For example you could set 2DL and 1UL where there are 2 carriers; one carrier of mixed slot type and one carrier full downlink slot type. CA1 will have a mixed slot and the user can configure the DL:UL ratio. CA2 will be a purely downlink slot, and DL:UL will be fixed as 1:0.
To get max DL throughput, Choose the configuration that provides maximum channel bandwidth, and the highest DL to UL Ratio
Thank you Abhishek. I believe the generally used ratios are 4:1 or 1:4, and I understand the choice would depend on which direction has more traffic
What is the maximum number of MIMO configurations supported in NetSim?
Upto 128 antennas in the gNB and 16 antennas in the UE. So maximum of 16 layers.
Would someone know some details of NetSim’s scheduler working in carrier aggregation mode?
Cheah Wei Leow Excerpt from documentation
In NetSim carrier aggregation (CA) is done in both DL and in the UL. When doing CA, the PHY layer is separate for each component carrier (CC). Thus, each CC will have a different pathloss, SINR and TBS. Then the resources of all component carriers (CCs) are pooled at the MAC, and scheduling is across the pooled resources. However, in practice each UE may be assigned resources from a particular CC. Since NetSim doesn’t currently model frequency selective channel fading, there is generally negligible difference in network performance between allotting from a pool vs. allotting from one CC. The exception is when the data demand from any UE is greater than the capacity of a CC.
