CNL - Wireless AI Connectivity           

The Communications and Networking Laboratory (CNL), led by Prof. Jaewoo So (소재우 교수), was established in September 2008 as the part of Department of Electronic Engineering at Sogang University. Our research covers AI technologies, Connectivity protocols, and Security for 5G/6G, V2X (Vehicle-to-everything), and IoT. Research topics are





  • Wireless AI - AI/ML Empowered 5G/6G, Connected Car, and IoT

    Artificial Intelligence (AI) empowered PHY, MAC, and network layers for 6G: AI, which learns from the perceived environment and can exploit the increasingly massive datasets available from wireless systems, can be used to solve complex and previously intractable problems. Many problems in wireless communication systems, such as decision making, resource optimization, and network management, can be cast in a form that is suitable to be solved by AI techniques. Hence, AI technologies have been applied to improve the performance of 5G/6G wireless communication systems.
    Deep learning (DL) for wireless resource allocation, CSI feedback, and interference mitigation: Resource management problems in systems and networking often manifest as difficult online decision making tasks where appropriate solutions depend on understanding the workload and environment. We apply recent DL technologies to wireless networks.
    Deep reinforcement learning (DRL) for wireless and mobile networking: The integration of DRL into future wireless networks will revolutionize the conventional model-based network optimization to model-free approaches and meet various application demands. By interacting with the environment, DRL provides an autonomous decision-making mechanism for the network entities to solve non-convex, complex model-free problems, e.g., spectrum access, handover, scheduling, caching, data offloading, and resource allocation.





  • Wireless Connectivity - Radio access technologies for 5G/6G, V2X, and IoT

    Integrated sensing and communication (ISAC) ISAC refers to the design paradigm and corresponding enabling technologies that combine sensing and communication systems to utilize resources efficiently and even to pursue mutual benefits. ISAC can acquire two main advantages over dedicated sensing and communication functionalities: 1) Integration gain to efficiently utilize congested resources for dual use of both communications and sensing, and even more interesting, 2) Coordination gain to balance dual-functional performance or/and perform mutual assistance. ISAC has been recently identified as an enabling technology for B5G/6G.
    5G/6G cellular connectivities cover architectures and protocols for 5G/6G wiereless communications and networking. Research topics are learning-based radio resource management, NR technologies for 5G and beyond, multiple-input multiple-output (MIMO), device-to-device communications, etc.
    Vehicle-to-everything (V2X) connectivities: C-V2X is a growing area of communications between vehicles and including roadside communication infrastructure. Advances in wireless communications are making possible sharing of information through real time communications between vehicles and infrastructure. This has led to applications to increase safety of vehicles and communication between passengers and the Internet.
    IoT connectivities cover NB-IoT, LoRa, Wi-Fi, and Bluetooth. Research topics are response time and energy efficiency of IoT devices discovery; wireless access and communications technologies; conectivity and clustering; network platforms; coexistance of BT/Wi-Fi in the crowded 2.4GHz networks; and qalfication and improvement of audio chooping over bluetooth A2DP.
