Refactor DLSCH scheduler Refactor the DLSCH post processor similarly to what has been done in !3521 with the goal of saving an additional iteration through all UEs, hopefully making the DLSCH scheduler faster. It further includes changes to make working with and debugging multi-UE operation easier: - add some measurements in L1 (for total TX/RX time) - a new option MACRLCs.[0].stats_max_ue to limit the number of UEs in the periodic output (default: 8, 0=disable) - avoid stack overflow in the MAC - fix the writing of stats to nrMAC_stats.log and nrL1_stats.log when the written output reduces by truncating the files - avoid to schedule retransmission with 0 RBs.
This document outlines how to use the OAI CI framework and gives a quickstart.

Quickstart
There is a script main.py that
- reads scenario files from XML
- executes the steps (e.g., deployment of CN/gNB/UE, attach, ping, ...)
To simplify, a script run_locally.sh can be used to run a single scenario
locally. First, download images for gNB&UE (we assume you already downloaded
the CN) and tag them "latest", which is expected by run_locally.sh:
docker pull oaisoftwarealliance/oai-gnb:develop
docker tag oaisoftwarealliance/oai-gnb:develop oai-gnb
docker pull oaisoftwarealliance/oai-nr-ue:develop
docker tag oaisoftwarealliance/oai-nr-ue:develop oai-nr-ue
Now, run the scenario:
cd ~/openairinterface5g/ci-scripts/
./run_locally.sh xml_files/container_5g_rfsim_simple.xml
Output should look like

it will run an end-to-end test, connecting one UE to the gNB, and ping, before
undeploying. As shown, logs will be under
/home/richie/oai/cmake_targets/log/container_5g_rfsim_simple.xml.d/. The
python code also produces an HTML report in ci-scripts/test_results.html.
Running with local changes
In order to run the tests as above, with local changes, please build images locally.
It is not yet possible to override an existing image with changes made locally to a source file and run it directly through the CI framework. However, it is possible to override an existing image with local changes, and run the scenario manually following the console logs steps provided above. This is described in the 5G RFsimulator README.
