Enhancing 5G RAN software (OpenAirInterface) by designing and implementing:

◦ 3GPP-compliant DRX at the MAC and RRC layers of the 5G access stack.

◦ O-RAN fronthaul interface between High PHY layer and commercial Radio Units (RU)

◦ RedCap (3GPP Release 17) support.

Deployment, Configuration and Validation of 5G testbeds (vRAN, vCore and UEs) for vertical trials.

Leading collaborative projects (6G-BRICKS, 5G-STREAM, IMAGINE-B5G, 6G-VERSUS).

Ensuring the readiness of EURECOM's 5G platform (OpenAirInterface).

Developed and maintained new features in 5G RAN (C, C++), including implementing 3GPP-compliant dynamic TDD and network slicing.

Conducted in-depth troubleshooting, performance testing, and debugging of 5G software in indoor/outdoor environments to host Vertical Experiments in EURECOM's 5G testbed.

Development of AI agents (Python) that configures the RAN using the O-RAN E2 interface:

◦ Dynamic TDD using DRL (DDPG) in the 5G!Drones EU-project for an AIRBUS MCX use case, optimizing DL/UL ratio to meet traffic demands.

◦ Abnormal traffic detection applied in the 6G-BRICKS EU-project.

◦ RLF prediction using LSTM and SVM models.

◦ Network slicing optimization by selecting numerology and BWP in simulated environments.

◦ Latency reduction by predicting the next grant in simulated networks.

◦ Dynamic TDD slot selection and interference mitigation in public networks.

Contributions to OAI gNB: Dynamic TDD with dynamic control via O-RAN E2 interface, analyze, troubleshoot and fix bugs in OAI gNB and eNB to use it in Vertical Experiments that requires high throughput and low latency (5G-Drones EU-project).

•Contributions to OAI 5G Core: design and implementation of an open-source 3GPP-compliant NWDAF, implementation of Event Exposure APIs in AMF/SMF.

Developed a low-level API enabling verticals to manage RAN slices, optimizing resource allocation at the physical layer.
