  • EU FP7 INFSO-ICT-317669 METIS, D2.4 Proposed solutions for new radio access
  • 2015
  • Reports (other academic/artistic)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.

  • Random Broadcast Based Distributed Consensus Clock Synchronization for Mobile Networks
  • 2015
  • In: IEEE Transactions on Wireless Communications. - 1558-2248 .- 1536-1276. ; 14:6, s. 3378-3389
  • Journal article (peer-reviewed)abstract
    • Clock synchronization is a crucial issue for mobile ad hoc networks due to the dynamic and distributed nature of these networks. In this paper, employing affine models for local clocks, a random broadcast based distributed consensus clock synchronization algorithm is proposed. In the absence of transmission delays, we theoretically prove the convergence of the proposed scheme, which is further illustrated by numerical results. In addition, it is concluded from simulations that the proposed scheme is scalable and robust to transmission delays as well as different accuracy requirements.

  • Resource Sharing and Power Allocation for D2D-based Safety-Critical V2X Communications
  • 2015
  • In: IEEE ICC 2015 Workshop. - : IEEE. - 9781467363051 ; , s. 2399-2405
  • Conference paper (peer-reviewed)abstract
    • Deploying direct device-to-device (D2D) links is considered an enabler for V2X applications, with intra-cell interference and stringent latency and reliability requirements as challenging issues.We investigate the radio resource management problem for D2D-based safety-critical V2X communications. Firstly, we analyze and transform the V2X latency and reliability requirements into mathematical forms that are computable using only slowly varying channel information. Secondly, we propose a problem formulation fulfilling the requirements of V2X, where resource sharing can take place not only between vehicles and cellular users but also among different vehicles. Moreover, a Resource Block Sharing and Power Allocation (RBSPA) algorithm is proposed to solve this problem. Finally, simulations are presented that indicate promising performance of the proposed RBSPA scheme.
