Phuong Nam. Tran

I am currently a Doctoral Researcher at the Centre for Wireless Communications (CWC) – Radio Technologies, University of Oulu, Finland, since January 2025. My main supervisor is Markku Juntti, with Nhan Nguyen as my co-supervisor. I am a Marie Skłodowska-Curie Doctoral Fellow in the EXACT-6G project, funded by the MSCA Doctoral Network (MSCA-DN) program.

Before joining the University of Oulu, I worked as a Research Assistant at the Singapore University of Technology and Design (SUTD) under the guidance of Zehui Xiong. I completed my Master’s degree in 2024 at Chung-Ang University (CAU), South Korea, under the supervision of Sungrae Cho, with close collaboration from Nhu-Ngoc Dao. I received my Bachelor’s degree in 2020 from the Hanoi University of Science and Technology (HUST), Vietnam.

My research interests include deep reinforcement learning for wireless communications, reconfigurable intelligent surfaces, cell-free massive MIMO, and multimedia streaming.

In the context of the increasing demand for Internet of Multimedia Things (IoMT) services, rate splitting multiple access (RSMA) and intelligent reflecting surface (IRS) technologies have been considered potential networking enablers to provide ultra-throughput wireless access. However, challenges arise due to the heterogeneity of IoMT devices and arbitrary network quality changes, resulting in unwanted service quality fluctuations and downgradation. This study addresses this problem by jointly optimizing wireless resource allocation and bitrate adaptation with Deep Reinforcement Learning (DRL)-based QoE management for IRS-aided RSMA-enabled IoMT streaming systems. We formulated the problem as a Markov decision process (MDP) and apply Proximal Policy Optimization (PPO) method to flexibly adjust IoMT bitrate, transmission beamforming, IRS phase shift, and RSMA parameters. As a result, our algorithm mitigates overestimation of client-side bandwidth, leading to smoother playback and reduced quality fluctuations. Simulations show that our approach outperforms baseline methods in terms of video resolution (up to 2.5 times) and achievable sum-rate (up to 50%), contributing to a superior streaming experience in IoMT systems.
