Towards Environment-Adaptive Wireless Access Network for 5G and Beyond
The 5th generation (5G) mobile communication systems are now about to be deployed worldwide. We need to prepare the rapid proliferation of 5G services. It is necessary to fully exploit the spatial dimension in radio access network (RAN) in 5G systems. In this talk, we will overview the wireless evolution from 1G to 5G systems. Then, we will point out that an environment-adaptive RAN consisting of distributed multi-input multi-output (MIMO) has a great potential of flexible deployment as well as achieving high spectrum and energy efficiencies. However, the radio resource management should handle a massive number of distributed antennas (DAs) and user equipments (UEs) and therefore, prohibitively high computational complexity is the biggest challenge in practice. This computational complexity problem can be alleviated by introducing location-based clustering of either DAs or UEs. For flexible deployment of RAN, a learning-based approach is essential. We will present the concept of the environment-adaptive RAN and discuss about its promising capability revealed by preliminary evaluation.

AI Computing Changes the Landscape of Communications and Networking – M2M Communications 2.0
AlphaGo inevitably advances the technology frontier in artificial intelligence (AI) computing. Together with Internet and big data analytics, new technological opportunities emerge, namely, autonomous vehicles, service robots, smart manufacturing, and AIoT. Starting from statistical communication theory and online adaptive methodology in communications, AI computing have had and will have significant impacts on the design of communication systems and networks. Furthermore, collective performance of smart machines indicates the need of machine-to-machine (M2M) communications that is fundamentally different from human-to-human (H2H) communication. Ultra-low latency is much more wanted than throughput for communication among smart machines. A disruptive and systematic approach to establish next-generation wireless networks will be introduced. Together with identified use cases identified by the ITU-T to apply machine learning to wireless networks, evolution toward future wireless network architecture for machine learning enables tremendous amount of smart machines in service, to realize the infinite technological opportunities toward future digital society.

Design Alternatives for Reliable and Scalable Data Acquisition From IoT Domains
In this work we discuss proxy architectures which interconnect IoT domains running CoAP with the rest of Internet including micro data centers and other domains building scalable hierarchical architectures. We assume that CoAP domain is terminated by an IoT proxy with cache, and describe and evaluate three design options for communication architecture. The first option is the default scenario with unicast communication using POST/GET messages, with proxy operating in forward or reverse mode, and reactive or proactive data collection. The second option is data collection via multicast GET messages from the proxy, including the impact of the leisure period which allows devices to reply after a arbitrary (random) delay upon receiving a multicast GET request. The final option is the use of ‘observe’ feature where clients subscribe to server notifications that inform them of changed data values. To maintain the freshness of cached records under random arrivals of observed data, we have implemented the evaluation of Max-Age parameter at the proxy. We have also implemented congestion control at IoT nodes which interacts with proxy’s freshness estimation and allows the proxy to perform its own congestion control. We present performance data of these options, including the probability of successful data transmission, round trip delay and energy consumption.

P2P network issues in a blockchain-based ledger
Interconnection network and its performance have a major impact on the performance of blockchain-based distributed ledgers. In this talk, we present a brief overview of the Bitcoin's blockchain distribution network, followed by a model of the data distribution algorithm, and some performance results pertaining to block and transaction propagation times, fork probability, network partitioning in case of a fork event,
and duration of the inconsistent state of the ledger. Values of individual model parameters are derived from recent measurements and business analysis reports. We model the data distribution algorithm using branching processes in the network with random distribution of node connectivity. Then we apply Jackson network model to the entire network in which individual nodes operate as priority M/G/1 queuing systems. Data arrival to the nodes is modeled as a non-homogeneous Poisson process where the distribution of arrival rate to the nodes is derived from the analytical model of data delivery protocol. We show that the three-way forking probability is substantially lower than that of a two-way forking and that the partition sizes in the case of two-way forking tend to equalize when the number of nodes increases. We also show that the duration of ledger inconsistency state exhibits long tail probability distribution which means that successive forking events can force the ledger to remain inconsistent for a long time.

Harmonization and Integration between Wireless Power and Data Transmissions Based on Regulatory Science
Microwave wireless power transmission/transfer (WPT) has been researched and developed to mostly reach to commercial products while it performs longer distance power transmission than conventional electromagnetic and magnetic induction schemes. Huge demand of WPT applications for mobile rechargeable devices for IoT and M2M in general, and specific use cases of UAV or drones for emergency rescue and parcel delivery, implant medical devices etc. is supporting its research and development. However, there are several remained problems for practical uses; (1)EMC and human body protection guidance for WPT, (2)interference of WPT to radio licence system (primary user in radio regulation), (3)mutual interference between WPT and non-licence radio system in secondary users, (4)improvement of electricity feeding efficiency of WPT devices and antennas, (5)regulatory compliance testing, (6)international standard for global business and so on. This talk will cover current state of art in WPT, in particular, according to analogy of wireless communication theory and technology, newly invented technologies in physical, data link (media access control; MAC), network layers will be introduced to solve the above-mentioned problems such as multi-hop relay of WPT, MAC protocol for WPT and so on. These new theories and technologies of WPT could be integrated together with conventional wireless communication ones. Moreover, harmonization between WPT and other radio applications will be discussed to achieve their coexistence by logical numerical evaluation of risk versus benefit of radio uses, derivation of regulatory compliance guideline from various viewpoints of stakeholders based on regulatory science. International standard of WPT will be also addressed shortly.

The Challenges of Connected and Automated Mobility
Connected and automated mobility is a global, ambitious programme, with a multipronged focus: improving safety, thus reducing deaths on the road, improving transportation efficiency whilst reducing the environmental impact, and improving the quality of the mobility experience, for drivers and passengers.
The challenges are not necessarily technological, rather mainly legal and regulatory, reflecting growing safety, security and privacy concerns.
The presentation will focus on open technology issues and on the first instantiations of cross-border corridors aiming at delivering initial CAM services. Emphasis will also be put on the underlying, conflicting business-models under consideration.

Large Intelligent Surfaces: One Step Beyond Massive MIMO
The evolution from 4G to 5G wireless systems was driven by the expected huge growth in user bit rates and overall required bit rates, and the same might be expect for beyond 5G systems. This means a substantial spectral efficiency increase, which must be achieved while maintaining or even improving the power efficiency. To accomplish this one needs to employ new transmission techniques, with the most promising ones based on the use of a large number of antennas. For this reason, massive MIMO (Multiple-Input and Multiple-Output) schemes, involving tens or even hundreds of antennas, are a key component of 5G, since they allow high capacity gains, while enabling significant power savings.
LIS (Large Intelligent Surfaces) are the natural evolution of massive MIMO schemes. They will involve many thousands of antenna elements, allowing huge capacity gains, as well accurate positioning and efficient energy harvesting techniques. However, the implementation of LIS techniques involves considerable challenges. The same way that massive MIMO cannot be regarded as a scaled version of conventional MIMO, LIS schemes cannot be regarded as scaled versions of massive MIMO.
In this talk we give an overview of LIS potentialities and challenges. We start by making an overview on the evolution from MIMO to massive MIMO, and its extension to LIS. Then we present the main features of LIS systems, as well as the implementation constraints and challenges, as well as potential solutions.
