These demands are directly driven by the consumer’s expectations, application requirements, and saturation of frequency bands used in current spectrum. The fifth generation (5G) of mobile communication networks, and specifically millimeter-wave (mmWave) New Radio (NR), aims to enable this future with ultra-low-latency, ultra-wideband services, opening up a whole new era of applications and services, much like 4G Long Term Evolution (LTE) did a decade ago. To enable 5G, the Third Generation Partnership Project (3GPP) is focusing on defining the technical specifications for NR technology, as well as enhancements to the current LTE. However, enabling and launching 5G NR presents both technological opportunities and challenges. In this column, we explore how 5G mmWave challenges are being approached in 3GPP standardization and how solutions can enable the technology to help achieve broader bandwidths and harness some of the inherent benefits of higher-frequency communications.","PeriodicalId":13497,"journal":{"name":"IEEE Wirel.

Through the UL only sharing known as UUDL decoupiing, 5G-NR provides a tool to extend its coverage with C -Band deployment, and makes it possible to deploy a C-Band 5G-NR network using existing LTE sites for seamless coverage. Moreover, the co -site deployment of 5G-NR and LTE greatly reduces the 5G-NR network cost and speeds up the 5G-NR commercialization. The UL sharing between LTE and 5G -NR also provides a powerful tool to strike a good balance between spectrum efficiency and low latency, and between coverage and channel bandwidth. The simultaneous 5G-NR DUUL sharing with an LTE DUUL carrier provides the possibility of early and low load 5G-NR deployment since the FDD LTE DL may have such high traffic load that only a shared low traffic load on 5G-NR DL can be accommodated. The 5G -NR is also designed to coexist with a TD-LTE system in the same TDD band to align the UUDL transmission direction. Overall, 5G-NR is designed to allow efficient coexistence with 4G LTE for very flexible deployments and use cases.","PeriodicalId":13497,"journal":{"name":"IEEE Wirel.

Since the telephone numbers have been assigned to machine-type devices, PSTN switches can play a role in IoT service routing. In this article we deploy a PSTN-based IoT mechanism where the interaction between the users and the IoT devices is achieved through PSTN switches. To our knowledge, this is the first PSTN-based IoT solution in the world. With this mechanism, all PSTN customer premises equipment (CPE; fixed-line and mobile phones) can access IoT services without installing any software (mobile apps). By reusing the existing PSTN infrastructure, PSTN-based IoT offers telecom-grade service, security, and network management for IoT, which are very expensive to build in non-PSTN-based IoT. Our approach conveniently enables the existing CPE to access IoT applications, which will significantly promote the IoT service industry.","PeriodicalId":13497,"journal":{"name":"IEEE Wirel.

IoT is a paradigm that involves networked physical objects with embedded technologies to collect, communicate, sense, and interact with the external environment through wireless or wired connections. With rapid advancements in IoT technology, the number of IoT devices is expected to surpass 50 billion by 2020, which has also drawn the attention of attackers who seek to exploit the merits of this new technology for their own benefits. There are many potential security and privacy threats to IoT, such as attacks against IoT systems and unauthorized access to private information of end users. As IoT starts to penetrate virtually all sectors of society, such as retail, transportation, healthcare, energy supply, and smart cities, security breaches may be catastrophic to the actual users and the physical world.

As a pure physical layer signal processing technology, NOMA was briefly studied In Release 14 study of fifth generation New Radio (5G NR) [2], with the focus on grant-free uplink transmission for the massive machine type communication (mMTC) scenario. Grant-based uplink NOMA was not high priority since it is more about scheduler implementation without much need for standardization. MUST (multi-user superposition transmission) was not borrowed for 5G NR downlink because of massive multiple-input multiple-output (MIMO) setup for > 3GHz deployment where the further gain from NOMA is marginal. The study was terminated in October 2016 so that the Third Generation Partnership Project (3GPP) can focus on more basic functionalities of 5G NR in Release 15. Even though Release 15 NR networks are largely orthogonal- multiple-access-based, there is strong interest in NOMA from both industry and academia. NOMA study was restarted in Release 15 [3], and applicable scenarios were expanded to ultra-reliable low-latency communication (URLLC) and enhanced mobile broadband (eMBB) . More than 16 NOMA schemes at the transmitter were proposed by over 14 companies.

In this column, we have reviewed the basic operation of a consensus mechanism, as well as the current trend of a DLT-based security model that is particularly important for loT. We further point out that, beyond application layer and security, DLT also has potential in other aspects of wireless networking such as computing and radio connectivity. Specifically, we see DLT as a perfect tool that should be leveraged to realize fog -RAN, as the consensus mechanism of DLT may be used to maintain tight synchronization among computing and networking resources in different locations. On the other hand, DLT could also be employed to avoid potential collision that may occur in grant -free uplink access. In summary, we believe that DLT will gradually become a key tool to reshape communication systems in a wide range of aspects, covering not just applications and security, but also connectivity and computing.","PeriodicalId":13497,"journal":{"name":"IEEE Wirel.

He has already taken brilliantly the office of EiC. In almost last three years, many things have been done to make significant improvements to this Journal. They range from the introduction of regulations that helped to make clear and more transparent the management and actions of all the officials (EiC, AEs, reviewers, etc.), a new definition of the time frame in which all the actions of the review process of a paper should be done, an EMC-oriented taxonomy of the reviewers’ competencies in order to facilitate their proper selection by the Associate Editors. Particular care has been given to the future of the publication by nominating young and competent new AEs that with their fresh energies and relevant scientific skills project the Transactions on the new frontiers of EMC. The T-EMC Advisory Board has been enriched by two members with a strong industrial background in order to offer their experience and views in steering the Transactions toward relevant and real-world topics. The Distinguished Reviewers Award has been continued and a new regulation for the Best Transaction Paper Award has been proposed and approved for a more selective and scientifically consistent choice of the winner.
