In this article, the authors introduce the theoretical underpinnings of #channel #charting and present an overview of recent algorithmic developments and experimental results obtained in the field. They furthermore discuss concrete application examples of channel charting to network- and user-related applications, and they provide a perspective on future developments and challenges as well as the role of channel charting in next-generation wireless networks. ---- Paul Ferrand, Maxime Guillaud, Christoph Studer, Olav Tirkkonen More details can be found at this link: https://lnkd.in/eM2fNFqB

The paper "On Exploiting User Equipment Relaying Capabilities in Beyond 5G Networks: Opportunities, Challenges, and Road Map" by Jordi Pérez-Romero, Oriol Sallent, Olga Ruiz has been published in IEEE Vehicular Technology Magazine (early access). The paper proposes a RAN augmentation approach through UE-to-network relaying for optimizing the coverage footprint and for bringing edge computing capabilities closer to the users.

This review article primarily discusses different types of interference challenges related to the #Ultra-#reliable #and #low-#latency #communications (#URLLC) systems using contemporary designs, frameworks, access modes, and enabling technologies for #beyond #fifth-#generation (#B5G) and #sixth-#generation (#6G) communication networks. They present state-of-the-art research work, in-depth analysis of interference problems, and guidance on the futuristic 6G URLLC technologies and communication networks. This study intends to provide a holistic vision of B5G/6G URLLC systems, their empirical aspects, limitations, essential techniques, and an outlook toward future research avenues. ---- Maraj Uddin Ahmed Siddiqui, Hanaa Abumarshoud, Lina Bariah, Sami Muhaidat More details can be found at this link: https://lnkd.in/gy76MgTe

In this paper, they systematically review the latest developments in quantum Internet protocols from the perspective of protocol stack layering.With the development of #quantum #technologies, the #quantum #Internet has demonstrated unique applications beyond the classical Internet and has been investigated extensively in recent years. In the construction of #conventional #Internet #software, the protocol stack is the core architecture for #coordinating #modules. How to design a protocol stack for the #quantum #Internet is a challenging problem. By summarizing and analyzing the progress in each layer’s protocols, they reveal the current research status and connections among the layers. ----@Yuan Li; @Hao Zhang; @Chen Zhang; @Tao Huang; F.

Nothing beats IEEE Communications Magazine for a deep dive into the future, five to ten years from now. The October issue focuses on quantum networks, which promise unbreakable security; simultaneous, distributed quantum sensing across multiple locations; and enhanced computational power achieved by connecting quantum computers through a quantum network. https://lnkd.in/gUzG8JbE

The cell-free massive MIMO exploits higher macro-diversity gain to provide uniformly good QoS. The dense deployment of APs escalates the network power consumption and the aggressive pilot sequence reuse leads to higher interference and pilot contamination. Our new paper, accepted for publication in IEEE Trans. Wireless Commun., explores the potential of low-resolution ADCs to suppress power consumption and rate-splitting multiple access (RSMA) to mitigate the ensuing interference. We optimize the common and private power allocations to maximize the sum-rate. Below is the link to the accepted paper: https://lnkd.in/gTFxKHWf

I am glad to share my article about accelerating data transaction at wireless communications for short delay-sensetive messages at the QUIC protocol. https://lnkd.in/eePNrTcT #fec #quic

This article provides an #overview of the trends in #radio #access #network (#RAN) slicing research with a focus on its technical, trading, and security aspects. Specifically, several algorithms proposed in RAN slicing research to solve the allocation, trading, and security issues are discussed. Then the authors present various critical challenges existing in resource sharing, as well as new research directions that may uncover novel techniques in the 5G and beyond paradigms. With this survey, they provide a blueprint to guide future research in RAN slicing. ---- Guolin Sun, Daniel Ayepah-Mensah, Gordon Owusu Boateng, Ph.D., Noble Arden Kuadey, Mohamed Basher Omer, Guisong Liu More details can be found at this link: https://lnkd.in/ebVZ8ewW

This paper consider #scalable #cell-#free massive multiple-input multiple-output networks under an open radio access network paradigm comprising #user #equipments (#UEs), #radio #units (#RUs), and #decentralized #processing #units (#DUs). UEs are served by dynamically allocated user-centric clusters of RUs. The corresponding cluster processors (implementing the physical layer for each user) are hosted by the DUs as software-defined virtual network functions . Unlike the current literature, mainly focused on the characterization of the user rates under unrestricted fronthaul communication and computation, in this work the authors explicitly take into account the #fronthaul #topology, the #limited #fronthaul #communication #capacity, and #computation #constraints at the DUs. In particular, they systematically address the new problem of #joint #fronthaul #load #balancing and #allocation #of #the #computation #resource. ---- Zhiyang Li, Fabian Göttsch, Siyao Li, Ming Chen, Giuseppe Caire More details can be found at this link: https://lnkd.in/eV9B9Tzs
