During the last two years, the METIS project ("Mobile and wireless communications Enablers for the Twenty-twenty Information Society") has been conducting research on 5G-enabling technology components. This paper provides a summary of METIS work on 5G architectures. The architecture description is presented from different viewpoints. First, a functional architecture is presented that may...
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...
The use of multiple transmit antennas at the base station and device side play an important role already in current 4G/LTE systems, enhancing system performance and extending the data rates that can be provided to the end user. For the future (5G) wireless-access solution advanced antenna solutions are expected to play an even more pronounced role. 5G wireless access needs to provide substantially...
METIS is developing a 5G system concept that meets the requirements of the beyond-2020 connected information society and supports new usage scenarios. To meet the objectives METIS uses Horizontal Topics (HT) that addresses a key new challenge, identifies necessary new functionalities and proposes HT-specific concepts. This paper presents an initial view of the HT-specific concepts for each of the...
The METIS project is laying the foundation of 5G mobile and wireless communication systems putting together the point of view of vendors, operators, third party players and academia. In particular, METIS is developing and evaluating the key technology components of 5G systems. In this framework, a new mobile and wireless network architecture is required to accommodate those technical enablers and...
The wireless-access networks of today will have to evolve in several dimensions in order to address the challenges and expectations of the future. New technology components will be introduced as part of the evolution of current wireless-access technologies, such as HSPA and LTE. However, additional components may also constitute future new wireless-access technologies, which may complement the evolved...
In 2020, mobile and wireless traffic volume is expected to increase thousand-fold over 2010 figures. Moreover, an increase in the number of wirelessly-connected devices to counts in the tens of billions will have a profound impact on society. Massive machine communication, forming the basis for the Internet of Things, will make our everyday life more efficient, comfortable and safer, through a wide...
Network densification and heterogeneous deployments are key tools to satisfy future traffic-volume and end-user service-level demands. LTE release 10/11 introduced several features to enhance LTE operation in heterogeneous deployments. This will continue as part of the work on small-cell enhancements in LTE Release 12. Especially, different forms of dual-connectivity are being considered to improve...
