Multiuser Millimeter Wave MIMO Channel Estimation with Hybrid Beamforming

Stefano Buzzi (University of Cassino and Lazio Meridionale/CNIT, Italy); Carmen D'Andrea (University of Cassino and Lazio Meridionale, Italy)

This paper proposes the use of subspace tracking algorithms for performing multiuser MIMO channel estimation at millimeter wave (mmWave) frequencies. The proposed approach relies on the TDD protocol and is based on two distinct phases; first of all, the BS sends a suitable probing signal so that all the MSs, using a subspace tracking algorithm, can estimate the dominant left singular vectors of their BS-to-MS propagation channel. Then, each MS, using the estimated dominant left singular vectors as pre-coding beamformers, sends a pilot sequence so that the BS, through a suitable processing, can estimate the corresponding right dominant channel singular vectors. We adapt the low-complexity projection approximation subspace tracking with deflation (PASTd) algorithm to our framework, and also take into account the hybrid analog/digital nature of the beamformer. Numerical results show the effectiveness of the proposed approach.

Josep Martrat (Atos, Spain); Sonia Castro (ATOS, Spain); Michael Bredel (NEC Laboratories Europe, Germany); Ricard Vilalta (CTTC/CERCA, Spain)

5GTANGO puts forth the flexible programmability of 5G networks with i) a NFV-enabled Service Development Kit (SDK) ii) a Store platform with advanced validation and verification mechanisms for VNFs/Network Services qualification (including 3rd party contributions) and iii) a modular Service Platform with an innovative orchestrator in order to bridge the gap between business needs and network operational management systems. We propose an integrated vendor-independent platform where the outcome of the development kit that is a packaged NFV forwarding graph of composed services, is automatically tested and validated in the Store for their posterior deployment with a customizable orchestrator compatible with common existing Virtual Infrastructure Managers (VIM) and SDN controllers. The combination of the proposed toolkit, validation Store and the service platform realises an extended multi-modal NFV DevOps model between service developers, telecom operators and vertical industries, increasing operational efficiency, facilitating the implementation and validation of new services and accelerating the adoption of NFV technologies.

Connected vehicles and cooperative intelligent transport systems (ITS) are foreseen to improve road traffic safety and efficiency; vehicle-to-anything (V2X) communication is one important enabler. While first V2X services will target assisted driving, based on communication technologies like ITS G5 and in future LTE/LTE-A/5G V2X. In the longer run advanced V2X services will evolve towards cooperative automated driving and collective perception of complex road traffic situations. The upcoming 5G standard will target such advanced V2X use cases with a promise of ultra-reliable low latency communications (URLLC) with guaranteed latencies down to 5 ms, support for high data rates, a system scalable to high vehicles densities, and with a flexible network architecture that also supports new business models. Besides the development and evaluation of 5G concepts in time for the 5G standardization, the 5G PPP Phase 2 5GCAR project will demonstrate three advanced V2X use cases with prototype network equipment on an automotive test track.

5G-Xcast is a new 5G-PPP project that will devise, assess and demonstrate large scale immersive media delivery by means of conceptually novel wireless technologies, contributing to the further definition of 5G and its standardisation. 5G-Xcast will focus on large scale media distribution, as this use case is one of the most demanding requirements in terms of data rate (capacity), scalability (cost-effectiveness) and ubiquity (coverage). The 5G-Xcast media delivery solution will have built-in unicast/multicast/broadcast modes and caching capabilities. The project will take a holistic approach in order to harmonize media delivery across the three communication modes being considered, and to provide a seamless user experience, as well as common application programming interfaces to content service providers. Special emphasis will be given to emerging new immersive media services that cannot be efficiently delivered by existing technologies and networks. 5G-Xcast will enable progressive convergence in the media delivery sector while optimising the resources of the available infrastructures, enabling new business models over fixed, mobile and broadcast networks that will be also investigated in the project.

The development toward programmatic operation and control of 5G networks is a compelling and technically challenging task. A fundamental component is the capability of exposing and controlling the network state across heterogeneous equipment in a unified manner. In this paper, we outline the COHERENT approach to network abstractions enabling unified representation and programming of heterogeneous radio access networks.

This paper discusses the challenges associated with the spectrum and radio access network (RAN) sharing in the next generation wireless systems. The considered scenarios assumes the virtualization of the network, where numerous metrics characterizing various features are abstracted and represented in form of a network graph. The latter is used by the by the dedicated entity, called centralized coordinator and controller, for realization of the sharing functionality. This paper addresses the use cases considered within the COHERENT project.

 

Measurement-based Protocol Design

Gorry Fairhurst (University of Aberdeen, United Kingdom (Great Britain)); Mirja Kuehlewind (ETH Zurich, Switzerland); Diego Lopez (Telefonica I+D, Spain)

The increasing public concerns about the interference of Internet traffic have led to a rapidly expanding deployment of encryption to protect end-user privacy, in protocols like QUIC. At the same time, network operators and access providers, especially in mobile networks, have come to rely on the in-network functionality provided by middleboxes both to enhance performance and support network operations. This presents a need for architectural changes and new approaches to the way network transport protocols are designed. This poster will explore the opportunities to use an experimentally-driven measurement-based approach to facilitate this network architecture evolution.

 

Effects of Cell Phone (Mobile) Radiofrequency Signal Exposure on Human Body

Mohammed Abdel Razek (King Abdulazize University, Saudi Arabia)

Electromagnetic fields are now an integral part of our life. Increasing in devices using electricity leads to growth in electromagnetic filed. Nowadays, all of us is exposed to a compound mix of EMF at numerous diverse frequencies, at street, home and at work. Most of the population use mobile phones and the usage of Mobile technology is rapidly growing as one of the powerful technologies resulting enormous increase in Mobile phone usage all over the world. Mobile phones use electromagnetic radiation in the microwave range, which has generated concern about possible negative effects of radiofrequency signals delivered to the human body. Our Hypothesis is "The influx of large numbers of people carried out mobiles to mass gathering events may give rise to specific hazardous to human health". This paper studies the effects of cell phone radiofrequency on the human body. It presents the weaknesses point in the human body could be effected by the radiofrequency.
