EU FP7 INFSO-ICT-317669 METIS, D1.1 Scenarios, requirements and KPIs for 5G mobile and wireless system
- 2013
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- This deliverable introduces generic scenarios based on fundamental challenges, and the specific problem description of test cases that will be relevant for beyond future radio access. Specific characteristics of each scenario and each test case include the key assumptions regarding requirements and key performance indicators. In order not to constrain the potential solutions, the requirements are specified from an end-user perspective. The deliverable will not only serve as the guideline for the technical work and system concept design in METIS, but also can serve in external research communities to help to harmonize the work towards the future radio access system including the new generation system of 5G

EU FP7 INFSO-ICT-317669 METIS, D2.1, Requirement analysis and design approaches for 5G air interface
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This document describes the problem space for the METIS research conducted in the radio link context. Firstly, a requirement analysis for the air interface design is conducted based on the test case descriptions presented in METIS deliverable D1.1. It follows an introduction of the research topics being pursued in the radio link research together with an illustration of how these topics are addressing the derived requirements. Moreover, it is shown which of thoserequirements address the needs of the METIS horizontal topics. To facilitate the achievement of these three objectives, a framework of General Requirements is introduced, which will be used throughout the project to assess and evaluate developed radio link solutions and to allow for measuring against the overall system performance goals.

EU FP7 INFSO-ICT-317669 METIS, D2.2 Novel radio link concepts and state of the art analysis
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This document provides a detailed overview of the Radio Link concepts being developed in METIS as well as a detailed analysis of the related state of the art. For each of the research topics identified for the radio link research covering flexible air interface, new waveforms,modulation and coding techniques as well as multiple access, medium access control and enablers for radio resource management, a detailed description of the aspects to be investigated will be given, going beyond the limits imposed by the systems operated today and their planned evolutions. The state of the art analysis, which is conducted for each of the research topics separately, covers current standards, their future evolutions as well as latest academic research. Elaborating on how the approaches followed in the radio link research may advance this state of the art carves a promising track towards innovative solutions addressing the challenges of future wireless communication.

EU FP7 INFSO-ICT-317669 METIS, D2.3 Components of a new air interface - building blocks and performance
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This document provides intermediate results of the concepts being developed in the radio link research of METIS. For each of the technology components (TeC) within the technology component clusters (TeCC), covering flexible air interface, new waveforms, modulation and coding techniques as well as multiple access, medium access control and enablers for radio resource management, key findings and conclusions collected so far are summarized in section 2. Continuative descriptions and research outcomes are given in the annex and referred publications.The results presented here will be extended in the further progress of the project, and they will be used in the next phase of the project to develop and refine the overall METIS system concept instantiated by the horizontal topics. The suitability of the single technology components for the overall system design being able to meet the wide range of requirements for 5G will then be evaluated.

EU FP7 INFSO-ICT-317669 METIS, D2.4 Proposed solutions for new radio access
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This deliverable represents the final report on the METIS radio link research. It provides a comprehensive and self-contained summary of all investigated technology components (TeCs), including evaluation results and conclusions on their potential for 5G. The METIS radio link research covers three main areas, which are considered key aspects for developing a self-contained air interface design for 5G: 1) Flexible air interface, 2) Waveforms, coding & modulation and transceiver design and 3) Multiple access, Medium Access Control (MAC) and Radio Resource Management (RRM). TeCs with similar research context and objectives have been grouped into clusters, whereof five have been selected as the most promising for 5G systems: From research area 1, TeC clusters providing key enablers for an air interface for ultra-dense networks (UDN) and for moving networks; from research area 2, multi-carrier transmission schemes with filtering; and from research area 3, novel access schemes for massive machine access as well as for non-orthogonal access.

5G : A tutorial overview of standards, trials, challenges, deployment, and practice

Tidskriftsartikel (refereegranskat)abstract
- There is considerable pressure to define the key requirements of 5G, develop 5G standards, and perform technology trials as quickly as possible. Normally, these activities are best done in series but there is a desire to complete these tasks in parallel so that commercial deployments of 5G can begin by 2020. 5G will not be an incremental improvement over its predecessors; it aims to be a revolutionary leap forward in terms of data rates, latency, massive connectivity, network reliability, and energy efficiency. These capabilities are targeted at realizing high-speed connectivity, the Internet of Things, augmented virtual reality, the tactile internet, and so on. The requirements of 5G are expected to be met by new spectrum in the microwave bands (3.3-4.2 GHz), and utilizing large bandwidths available in mm-wave bands, increasing spatial degrees of freedom via large antenna arrays and 3-D MIMO, network densification, and new waveforms that provide scalability and flexibility to meet the varying demands of 5G services. Unlike the one size fits all 4G core networks, the 5G core network must be flexible and adaptable and is expected to simultaneously provide optimized support for the diverse 5G use case categories. In this paper, we provide an overview of 5G research, standardization trials, and deployment challenges. Due to the enormous scope of 5G systems, it is necessary to provide some direction in a tutorial article, and in this overview, the focus is largely user centric, rather than device centric. In addition to surveying the state of play in the area, we identify leading technologies, evaluating their strengths and weaknesses, and outline the key challenges ahead, with research test beds delivering promising performance but pre-commercial trials lagging behind the desired 5G targets.
