The METIS 5G System Concept: Meeting the 5G Requirements

The development of every new generation of wireless communication systems starts with bold, high-level requirements and predictions of its capabilities. The 5G system will not only have to surpass previous generations with respect to rate and capacity, but also address new usage scenarios with very diverse requirements, including various kinds of machine-type communication. Following this, the METIS project has developed a 5G system concept consisting of three generic 5G services: extreme mobile broadband, massive machine-type communication, and ultra-reliable MTC, supported by four main enablers: a lean system control plane, a dynamic radio access network, localized contents and traffic flows, and a spectrum toolbox. This article describes the most important system-level 5G features, enabled by the concept, necessary to meet the very diverse 5G requirements. System-level evaluation results of the METIS 5G system concept are presented, and we conclude that the 5G requirements can be met with the proposed system concept.

5G service requirements and operational use cases: Analysis and METIS II vision

One of the objectives of METIS-II project is to facilitate discussion on scenarios, use cases, KPIs and requirements for 5G, building upon the comprehensive work conducted in the METIS-I project and taking the work of other European projects as well as other bodies such as ITU-R, NGMN, etc. into account. This paper analyses the landscape of 5G use cases and presents METIS-II 5G use cases that cover the main 5G services, have stringent requirements and whose technical solutions are expected to serve other similar use cases as well. It also links these use cases to the business cases defined by 5G PPP so that requirements of vertical industries can be taken into account when designing the 5G Radio Access Network (RAN).

Energy saving techniques for LTE: Integration and system level results

This paper focuses on energy saving techniques for LTE, and what overall energy savings they can achieve. The considered techniques are adaptive base station hardware, cell DTX, antenna muting, and adaptive sectorization. The paper discusses how these can be integrated and jointly save energy, and evaluates the energy savings as well as the quality of service impact by means of extensive system level evaluations of a radio access network. The system level simulations, which are carried out over 24 hours in a country-wide LTE network, indicate that these techniques together can provide energy savings in the order of 75% with only minor impact on quality of service.

METIS research and standardization: A path towards a 5G system

METIS has been conducting research on 5G-enabling technology components the last two years and the METIS 5G system concept is being developed. Concurrently the 5G requirements are being developed in ITU-R. Standardization of relevant technology components is the next step towards the deployment of 5G systems. In this article we outline the METIS 5G concept and how it will be further refined in Horizon 2020 projects before being brought to 3GPP and other relevant standardization bodies.

Fifth-Generation Technologies for the Connected Car: Capable Systems for Vehicle-to-Anything Communications

Two strong technology trends, one in the mobile communications industry and the other in the automotive industry, are becoming interwoven and will jointly provide new capabilities and functionality for upcoming intelligent transport systems (ITSs) and future driving. The automotive industry is on a path where vehicles are continuously becoming more aware of their environment due to the addition of various types of integrated sensors. At the same time, the amount of automation in vehicles increases, which, with some intermediate steps, will eventually culminate in fully automated driving without human intervention. Along this path, the amount of interactions rises, both in-between vehicles and between vehicles and other road users, and with an increasingly intelligent road infrastructure. As a consequence, the significance and reliance on capable communication systems for vehicleto-anything (V2X) communication is becoming a key asset that will enhance the performance of automated driving and increase further road traffic safety with combination of sensor-based technologies [1].
