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.

Tidskriftsartikel (refereegranskat)abstract
- Future 5G systems have set a goal to support mission-critical Vehicle-to-Everything (V2X) communications and they contribute to an important step towards connected and automated driving. To achieve this goal, the communication technologies should be designed based on a solid understanding of the new V2X applications and the related requirements and challenges. In this regard, we provide a description of the main V2X application categories and their representative use cases selected based on an analysis of the future needs of cooperative and automated driving. We also present a methodology on how to derive the network related requirements from the automotive specific requirements. The methodology can be used to analyze the key requirements of both existing and future V2X use cases.

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.

Ingår i: 2016 IEEE International Conference on Communications, ICC 2016. ; , s. Art. no. 7511128-
-
Konferensbidrag (refereegranskat)abstract
- This paper investigates the power control problemfor broadcast vehicular communications in the presence ofadjacent channel interference (ACI). First, we study the impactof ACI on vehicle-to-vehicle (V2V) communications and concludethat the ACI indeed significantly affects the reliability of V2Vlinks. Second, we formulate a power control optimization problemfor vehicles to reduce the negative influence of ACI, which isshown to be NP-hard. Furthermore, we propose two powercontrol schemes where the first one solves the formulated problemby a branch and bound method and the second one considersa heuristic algorithm with much reduced complexity. Finally,simulations are presented which illustrate the necessity of powercontrol when ACI exists and also show promising performanceof the proposed algorithms.

Cluster-Based Radio Resource Management for D2D-Supported Safety-Critical V2X Communications
- 2016
-
Ingår i: IEEE Transactions on Wireless Communications. - : IEEE Press. - 1558-2248 .- 1536-1276. ; 15:4, s. 2756-2769

Tidskriftsartikel (refereegranskat)abstract
- Deploying direct device-to-device (D2D) links is a promising technology for vehicle-to-X (V2X) applications. However, intracell interference, along with stringent requirements on latency and reliability, are challenging issues. In this paper, we study the radio resource management problem for D2D-based safety-critical V2X communications. We first transform the V2X requirements into the constraints that are computable using slowly varying channel state information only. Secondly, we formulate an optimization problem, taking into account the requirements of both vehicular users (V-UEs) and cellular users (C-UEs), where resource sharing can take place not only between a V-UE and a C-UE but also among different V-UEs. The NP-hardness of the problem is rigorously proved. Moreover, a heuristic algorithm, called Cluster-based Resource block sharing and pOWer allocatioN (CROWN), is proposed to solve this problem. Finally, simulation results indicate promising performance of the CROWN scheme.

Konferensbidrag (refereegranskat)abstract
- Direct device-to-device (D2D) communication has been proposed as a possible enabler for vehicle-to-vehicle (V2V) applications, where the incurred intra-cell interference and the stringent latency and reliability requirements are challenging issues. In this paper, we investigate the radio resource management problem for D2D-based V2V communications. Firstly, we analyze and mathematically model the actual requirements for vehicular communications and traditional cellular links. Secondly, we propose a problem formulation to fulfill these requirements, and then a Separate Resource Block allocation and Power control (SRBP) algorithm to solve this problem. Finally, simulations are presented to illustrate the improved performance of the proposed SRBP scheme compared to some other existing methods.
