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, D4.2 Final report on trade-off investigations
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Research activities in METIS WP4 include several aspects related to the network-level of future wireless communication networks. Thereby, a large variety of scenarios is considered and solutions are proposed to serve the needs envisioned for the year 2020 and beyond. This document provides vital findings about several trade-offs that need to be leveraged when designing future network-level solutions. In more detail, it elaborates on the following trade-offs:• Complexity vs. Performance improvement• Centralized vs. Decentralized• Long time-scale vs. Short time-scale• Information Interflow vs. Throughput/Mobility enhancement• Energy Efficiency vs. Network Coverage and CapacityOutlining the advantages and disadvantages in each trade-off, this document serves as a guideline for the application of different network-level solutions in different situations and therefore greatly assists in the design of future communication network architectures.

Clustering Schemes for D2D Communications Under Partial/No Network Coverage
- 2013
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Device-to-Device (D2D) communication has been proposed to support local services by enabling devices to directly connect to each other when being in proximity. To start direct communications, a device must first discover that other devices are in the proximity and that they are relevant in a certain context (i.e. can offer a specific service). This task becomes particularly challenging in out-of-network coverage. In this paper, we propose three clustering schemes that assist a device discovery and associating with other devices found relevant in a given context. We compare the efficiency of the proposed approaches in terms of discovery ratio, clustering time and energy consumption and study the tradeoff between these performance metrics that need to be considered when selecting one of the grouping schemes. In particular, the simulation results prove that grouping devices based on their capabilities taking into account the exchanged radio signal strengths ensure, in most of the scenarios, the balance between high discovery ratio, short latency and energy efficiency. This work has been partially performed in the framework of the FP7 project ITC 317669 METIS.

5GCAR project D3.1 Intermediate 5G V2X Radio
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The 5GCAR project aims to contribute to 5G network design, and specifically to design V2X technology components for V2X use case classes identified in the project. The requirements on reliability, latency, data rates, spectral and energy efficiency cannot be fully supported by today’s wireless networks and V2X solutions and call for novel and innovative approaches, including the design of a new radio interface.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Cellular network assisted Device-to-Device (D2D) communication has the potential to increase the network capacity, offload access and core network resources and reduce latency. To realize these potential gains and to ensure a win-win type of coexistence between the cellular and the D2D layer, there is a need to carefully design the procedures for radio resource management (RRM). This paper develops and evaluates low complexity radio resource management (RRM) algorithms that are based on practically feasible and well known measurements. These RRM algorithms include mode selection, power control, and resource allocation. First, the network assists D2D users on a coarse time scale to select D2D (direct) mode or cellular mode. Subsequently, the network informs the D2D users of tolerable power levels which cause minimal interference to the base station, and the possible resources that can be used for D2D communications. Based on this information, the D2D users act autonomously for executing the RRM functions. The simulation result shows that our approach to D2D RRM can harvest the offloading/proximity gain to the network.
