**About the role**:
**Multi-dimension resource allocation in 6G O-RAN evolution**

Context
Disaggregated 6G O-RAN architecture allows to combine solutions from different vendors. The openness of 6G O-RAN architecture allows Orange to integrates its own algorithms. The new architecture proposed by the O-RAN Alliance defines 3 levels of decision making (real time, near real time and non-real time) in a cloud based distributed architecture that also should take into consideration the compute resource allocation together with radio resources. O-RAN natively support AI/ML and optimization algorithms for both communication and computation resources.

Objective
This work aims at studying and developing multi-dimensional resource allocation mechanisms in the context of 6G O-RAN networks. It should take into consideration the support of both vertical communication across entities (e.g. for the radio resource communications between distributed and centralized units, and between O-CUs and the orchestration layer) and horizontal communications among resource controllers, happening not only at the orchestration layer but also at the near-real time scheduling level.
- Identify performance and load metrics and KPIs
- Joint radio/transport and compute resources allocation and scheduling
- Propose evolution of O-RAN open interfaces for supporting targeted use cases
- The expected outcome are:

- Identify the most relevant use cases in the context of Heidis project
- Develop a model that addresses both radio/transport and computing resources
- Propose and implement algorithms based on Mathematical Optimization and AI
- Performance evaluation and analysis
- Final report

**About you**:
Post-doc with skills in:

- Mathematical Optimization
- Online optimization
- Network virtualization / radio access networks
- Fluent technical reading and writting, development skills
- Some knowledge in AI techniques
