Workshop on Emerging Radio Access Network Technologies for B5G/6G (eRAN)

Scopes and Topics:

The next generation mobile communications network is envisioned to face both significant user-side paradigm shifts and network-side challenges. On the one hand, trillions of IoT devices will connect to the network, and astronomical amount of data uploading traffic will deplete network bandwidth. Also, users will prefer more personalized services. On the other hand, network costs (e.g., infrastructure deployment and energy costs) are surging, and high-quality spectrum resources have been exhausted. In order to face the above changes, traditional RAN need to be re-designed, and the novel RAN should fulfill design objectives including flexibility, scalability, and cost-efficiency. For example, in recent years, the design philosophy of functional decoupling has become prevailing, such as microservice architecture. The idea of decoupling has also been extensively adopted in RAN. For example, in 5G, UL/DL decoupling introduces the separation of uplink and downlink spectrum, so as to enhance uplink coverage by using lower bands. The cell-free architecture decouples a UE and its associated base station in a user-centric manner. For B5G/6G, by leveraging the enabling technologies such as Cybertwin, AI, and edge Intelligence, the emerging RAN architecture will aim to solve existing issues from spectrum utilization, service provision and cost reduction perspectives. For instance, the Cybertwin-enabled fully decoupled RAN (FD-RAN) has been proposed recently. In FD-RAN, functions of traditional base stations are physically split into three isolated entities, namely control, uplink and downlink base stations, which serve duplex control signaling, simplex uplink and downlink data transmission, respectively. In this way, advanced cooperative transmission techniques such as coordinated multi-point (CoMP), receiver diversity, and hybrid duplex resource allocation can be naturally implemented. Also, edge-enhanced Cybertwin serves to orchestrate user’s data transmission in FD-RAN.

This workshop seeks original unpublished papers focusing on design, enabling technologies and potential challenges on emerging RAN design and technologies for B5G/6G, such as the UL/DL decoupling technology and cell-free architecture. Topics of interest for this workshop, include, but are not limited to:

  • Architecture for emerging B5G/6G RAN
  • Theoretical analysis of emerging B5G/6G RAN
  • Cooperative resource management in emerging B5G/6G RAN
  • Network deployment in emerging B5G/6G RAN
  • Emerging B5G/6G RAN for V2X applications
  • Open and shared paradigm of emerging B5G/6G RAN
  • Cybertwin-assisted B5G/6G RAN
