Cost-Efficient 6G Radio Access Network
for Internet-of-Everything

Objective:

The fourth industrial revolution is accelerating a wave of digital transformation across industries through the deployment of digital twins, high-fidelity virtual replicas of both physical systems and abstract entities. These models provide transformative capabilities, from reducing operational inefficiencies in manufacturing to optimizing infrastructure maintenance in sectors like water distribution and energy. However, to function at scale, digital twins require real-time, bidirectional data exchange between vast networks of IoE devices and cloud-hosted digital shadows, placing significant demands on the underlying communication infrastructure.

In this context, the project tackles the core challenge of sustaining massive connectivity. Recognizing the limited capabilities of many IoE devices, the approach prioritizes resource allocation strategies that minimize the volume of data exchanged with digital counterparts, optimize radio resource utilization, and enable scalable, distributed network management.

The project focuses on building an NG-RAN that is both intelligent and spectrum-efficient. Rather than reshaping the network architecture, the project emphasizes the integration of distributed intelligence, development of massive access strategies under limited spectral resources, and distributed/autonomous control. The project also explores how to minimize communication between IoE devices and their digital twins, thereby improving energy and bandwidth efficiency.

The proposed solution follows three phases:

  • Advance the state of the arts pertains mmWave for mobile devices.
  • Enhancing spectrum utilization to support massive connectivity
  • Integrating distributed intelligence at the network for cost-effective and automated NG-RAN operations. This approach aims to create a scalable, low-cost, and intelligent 6G RAN, ensuring widespread and affordable connectivity.
