Spectrum sharing between terrestrial 5G and incumbent networks in the satellite bands presents a promising avenue to satisfy the ever-increasing bandwidth demand of the next generation wireless networks. However, protecting incumbent operations from harmful interference poses a fundamental challenge. This paper proposes a context-aware method of managing interference.
An In-Depth Survey on Virtualization Technologies in 6G Integrated Terrestrial and Non-Terrestrial Networks – Arxiv
Terrestrial and Non-Terrestrial Network integration faces a number
of challenges that could be addressed through network virtualisation technologies such as Software-Defined Networking, Network Function Virtualization and network slicing. In this survey, we provide a comprehensive review on
the adaptation of these networking paradigms in 6G networks.
This paper focuses on the
optimal waveform design for communication-assisted sensing
(CAS) systems within the context of 6G perceptive networks. The waveform design aims to minimise the sensing distortion at the user end while adhering to the SCT and power budget constraints.
Semiconductor quantum dots (QDs) so far have exhibited exceptional performance as key elements, i.e., quantum light sources and spin-photon interfaces, for quantum repeaters, but only in the near-infrared (NIR) regime. This review presents the physics and the technological developments towards epitaxial QD devices emitting at the telecom O- and C-bands for quantum networks. The paper also discusses the challenges and opportunities to realise future telecom QD devices with improved performance and expanded functionalities by taking advantage of hybrid integration.
A group of researchers in Japan has replicated the way that light would behave if it were subject to gravity, supporting a recent scientific theory about pseudogravity.
According to the theory, pseudogravity, a phenomenon replicating the effects of gravity, can be achieved by deforming crystals in the lower frequency region.
As engineers and scientists begin to develop 6G technology, uncomfortable questions need to be addressed, including what the point of 6G is, how it will be monetised, and what sort of experience it will deliver.
5G has taught us that the ‘build it and they will come’ approach won’t work. In contrast, 6G must be customer centric, not network centric, and start with a far clearer proposition around customer value.
In this green paper we explore what’s needed to make 6G a success.
Beyond Speed defines specific social and economic outcomes to which Next G can contribute, key aspects of digital equity, defining a trustworthy 6G network and how Next G connectivity will directly impact economic growth. Challenges in areas including supply chain and equal access are addressed as well as those that may arise when defining QoL metrics. This paper also presents promising areas for future research and issues a call to action for research, development, policies and business models.
A comprehensive survey on quantum computer usage: How many qubits are employed for what purposes? – Arxiv
Most news on quantum computers (QCs) consists of outstanding
experiments, and thereby we may overlook how typical usages of QCs have been. Such oversight,
if exists, could lead to an insufficient understanding of the present situation in the research and development of QCs and may
result in possible obstacles to long-term research design. In other words, we need an alternative perspective based on typical
usages as well as the standard one based on monumental experiments.
Architecture determines what and how the network services are provided, as well as the overall system efficiency, scalability, etc. This article proposes high-level designs of the 6G architecture. Three key innovation motivations are analysed and the gaps of 5G network are identified according to the operator’s experience in real large-scale network deployment. Those observations help to generate the key “Design Principles” about the 6G architecture.
