  • EU FP7 INFSO-ICT-247223 ARTIST4G, D3.4 Relay configurations
  • 2011
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • The following document contains proposals for innovations on relay configurations made by partners involved in the Artist4G project WP3, Task 3.3. The different relay configurations are for in-band and out-band relays, multi-hop relays, and moving relays. For each innovation, a description, the potential deviation from a defined baseline architecture, and simulation results (as far as available) are included. Important issues regarding the innovations impact on the architecture are pointed out and analysed in detail. This analysis will also be forwarded to WP4.

  • CELTIC CP5-026 WINNER+, D2.2 Enabling Techniques for LTE-A and beyond
  • 2010
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This deliverable summarizes the most promising enabling techniques for LTE-A and beyond in seven major areas. These areas are: Carrier Aggregation, Coordinated Multipoint Systems, Femtocells, Network Coding, MIMO, Quality of Service, Resource allocation, and Relaying. A description of the most relevant scenarios where the techniques can be used is given. Further the end-2-end performance approach is presented. Finally future research directions of enabling techniques beyond LTE-A are given.

  • EU FP7 INFSO-ICT-247223 ARTIST4G, D3.5c Moving Relays and Mobility aspects
  • 2012
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This deliverable presents analysis and simulation results related to moving relays and mobility optimization for relay enhanced networks. The results reported in this deliverable are ranging from fundamental performance limits expressed in terms outage probability to practical implementations of the moving relay concepts through architecture discussion, coordinated moving relays and network coded moving relays.

  • 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.

  • Frame Structure Design for Future Millimetre Wave Mobile Radio Access
  • 2016
  • Ingår i: 2016 IEEE Globecom Workshops (GC Wkshps), 4-8 Dec. 2016. - 2166-0069.
  • Konferensbidrag (refereegranskat)abstract
    • 5th generation cellular systems will extend the operation to above 6 GHz to meet extreme data rate requirements. This sets new requirements for the air interface design. In this paper, we propose several frame structure solutions from the mmMAGIC project [1], which address the challenges of using higher carrier frequencies. These solutions include subframe structures for orthogonal frequency division multiplexing (OFDM) and filter-bank multicarrier modulation (FBMC), demodulation reference signal (DMRS) design, backhauling, synchronization signal design and beam measurement reference signal design. Further research is being conducted to refine the overall frame structure solution.
