Following frequency change in the pipeline, we observed degraded UL channel conditions resulting in low UL throughput. Increasing attenuation on the gNB side was found to mitigate this issue by improving UL channel quality and reducing UL noise power. Increase tested UL and DL bitrates in OAIUE pipeline.
