Outline

This paper addresses the limitations of existing general-purpose LLMs for integrating Large-Scale Language Models (LLMs) into Open Radio Access Networks (O-RAN) and introduces the ORANSight-2.0 initiative to develop an O-RAN-specific baseline LLM. ORANSight-2.0 improves the performance of O-RAN-specific tasks by fine-tuning 18 models with parameter ranges from 1B to 70B based on five open source LLM frameworks, Mistral, Qwen, Llama, Phi, and Gemma. In particular, a new Retrieval-Augmented Generation (RAG)-based instruction coordination framework called RANSTRUCT is used to generate a high-quality instruction coordination dataset, which is then fine-tuned using QLoRA. For performance evaluation, a new srsRAN-based benchmark, srsRANBench, is proposed.

Takeaways, Limitations

Takeaways:
By developing an open source-based LLM specialized for O-RAN, we reduce dependence on existing closed models and expand the potential of LLM utilization in the O-RAN field.
It provides a standardized environment for O-RAN LLM development and evaluation by introducing new frameworks and benchmarks such as RANSTRUCT and srsRANBench.
We develop and evaluate models applicable to real environments by utilizing srsRAN, a 5G O-RAN stack.
Limitations:
Since the evaluation is currently conducted using only srsRAN-based benchmarks, further validation of generalizability to other O-RAN systems is required.
There is a lack of quantitative analysis on the degree of performance improvement of ORANSight-2.0 and comparative analysis with other existing LLMs.
A detailed analysis of the efficiency and scalability of RANSTRUCT is needed.
