Issue Description

[Describe the issue in detail] We are trying to produce a simulation of 20 UEs on an eNb or 5G connected to an EPC or 5G core. In both these cases, we want to be able to get 142 Mbs on a 20 Mhz channel. However, we are not able to get more than single digit Mbps transfer. So we have some questions on where we can configure certain parameters, For example, where can we do PRBs, CQI, MCS, Bandwidth, Frequency (Band) and Power of the radio.

Setup Details

[Specify details of the test setup. This would help us reproduce the problem reliably] e.g. Network configuration, Operation System, Hardware, RF front-end, library and driver versions This would help us reproduce the problem reliably] e.g. Network configuration, Operation System, Hardware, RF front-end, library and driver versions 20 UEs, 1 eNb, 1 EPC with iPerf running to test the transfer speed.

Expected Behavior

[What you expect to happen] Speed of close to 142 Mbps

Actual Behaviour

[What happens instead e.g. error message] 4.6 Mpbs or lower.

Steps to reproduce the problem

[Tell us how to reproduce this issue e.g. RF setup, application config files] Set up a 20 UEs connected to 1 eNb and 1 EPC.

Additional Information

[Any additional information, configuration or data that might be necessary to reproduce the issue] When we turn of logging, speed increases marginally. configs.zip logs.zip
