Special Issue Information

Dear Colleagues,

Future 5G networks promise delivering optimized services in three main usage scenarios: Enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and Massive Machine Type Communications (mMTC). The standardization of 5G has reached its first milestone with the 3GPP Release 15, while Release 16 is being clarified and first commercial products will soon appear on the market.

Compared to 4G, 5G pushes the usage of radio spectrum to the next level and enables the configuration of both radio access and the core network segments, thanks to the concept of network slicing and the use of virtualization technologies. Future 5G seeks to connect a denser more diverse range of devices, at far higher speeds with far lower latency and constitutes one of the most ambitious and challenging technology rollouts of the modern era. The success of 5G will depend to a great extent on how it is embraced by the new type of customers that 5G targets: the vertical industries. Practical experience with 5G deployments is needed, from customers, network operators and equipment vendors. In parallel to this, there are already some "beyond-5G" efforts appearing.

The goal of this Special Issue is to share research efforts on the design, adaptation and enhancement of beyond-5G mobile networks. Topics of interest include, but are not limited to:

  • Practical experience on 5G deployment and usage. Lessons learned towards beyond-5G enhancements.
  • Improvements of radio spectrum usage, novel strategies for coverage/service extension, support of novel use cases and mobile edge cloud applications, usability of the current unexplored spectrum.
  • Enhancements of mobile network architectures aiming at significantly reducing energy consumption.
  • Closed-loop automation and SLA control of automated vertical service lifecycle management.
  • AI-based E2E network slicing solutions to combine optimization of RAN, Transport, Core and cloud/MEC resources, across multi-technologies, multi-vendors and multi-domains (federation).
  • Applicability of AI/ML techniques to cross-layer optimizations in mobile network architectures.
  • Enhancements to NFV MANO based on AI/ML.
  • Orchestration and automation mechanisms capable of coping with extreme distributed and volatile resources (fog computing).
  • Machine learning techniques to optimize time and frequency slot allocation and minimize interference between devices in ultra-dense environments.
  • Optimal placement and movement of compute resources within a very distributed, mobile and heterogeneous infrastructure, including path movement prediction mechanisms to allow "follow-me" approaches.
  • Beyond-5G related standardization efforts in the relevant standardization bodies (IEEE, IETF, 3GPP and ETSI).

This paper presents a baseline roadmap for the evolution of 5G new radio over the next decade. Three timescales are considered, namely short-term (2022-ish), medium-term (2025-ish), and long-term (2030-ish).

This paper presents a baseline roadmap for the evolution of 5G new radio over the next decade. Three timescales are considered, namely short-term (2022-ish), medium-term (2025-ish), and long-term (2030-ish). The evolution of the target key performance indicators (KPIs) is first analyzed by accounting for forecasts on the emerging use cases and their requirements, together with assumptions on the pace of technology advancements. The baseline roadmap is derived next by capturing the top-10 and next the top-5 technology trends envisioned to bring significant added value at each timescale. Being intrinsically predictive, our proposed baseline roadmap cannot assert with certainty the values of the target KPIs and the shortlisting of the technology trends. It is, however, aimed at driving discussions and collecting feedback from the wireless research community for future tuning and refinement as the 5G evolution journey progresses. Full article

Framework for Delay Guarantee in Multi-Domain Networks Based on Interleaved Regulators

The key to the asynchronous traffic shaping (ATS) technology being standardized in IEEE 802.1 time sensitive network (TSN) task group (TG) is the theorem that a minimal interleaved regulator (IR), attached to a FIFO system does not increase delay upper bound while suppresses the burst accumulation. In this work it is observed that the FIFO system can be a network for flows that share same input/output ports and same queues of the network, and are treated with a scheduling scheme that guarantees the FIFO property within a queue. Based on this observation, a framework for delay bound guarantee is further proposed, in which the networks with flow aggregates (FAs) scheduling and minimal IRs per FA attached at the network edge are interconnected. The framework guarantees the end-to-end delay bound with reduced complexity, compared to the traditional flow-based approach. Numerical analysis shows that the framework yields smaller bound than both the flow-based frameworks such as the integrated services (IntServ) and the class-based ATS, at least in the networks with identical flows and symmetrical topology.
