As the eyes of the world turn to the Mobile World Congress in Barcelona (February 25-28), Ericsson Research reveals what´s next in key areas.
The 2013 Johannesberg Summit brings together wireless/mobile industry R&D leaders with leading academics to probe into the future of wireless. It is an annual forum to discuss trends, ”what’s hot and what’s not”, that may influence to long range developments of the Industry.
Ericsson and 29 partners launch METIS, a large EU co-funded research project which aims to keep Europe at the forefront of development of the future mobile and wireless system.
This paper provides a high-level overview of LTE Rel-10, sometimes referred to as LTE-Advanced. First, a brief overview of the first release of LTE and some of its technology components are given, followed by a discussion on the IMTAdvanced requirements. The technology enhancements introduced to LTE in Rel-10, carrier aggregation, improved multiantenna support, relaying and improved support for heterogeneous deployments, are described. The paper is concluded with simulation results, showing that LTE Rel-10 fulfills and even surpasses the requirements for IMT-Advanced.
The objective of this paper is to improve the knowledge on directional channel characteristics at the base station, particularly concerning elevation. For this purpose a channel measurement campaign has been performed. A powerful new method for super-resolution channel estimation has been used to get a detailed picture of the directional characteristics of the channel. This has further led to improved knowledge of when processes like diffraction over rooftops and/or specular reflections are important. The findings herein have been incorporated into a model for the elevation angle dispersion which is proposed as an extension to some commonly used directional channel models such as the ITU-IMT-Advanced model.
This paper proposes a technique to enhance the load-spreading algorithms used by IEEE 802.1aq Shortest Path Bridging. Its benefits are balanced network utilization and the new ability to apply subtle modifications to the distribution of the traffic matrix.
This paper discusses problems in content distribution and real-time interpersonal communication services (such as voice and video) with sufficient quality over best-effort networks. Quality as perceived by the user is important, but context dependence is essential for delivering services that are "good enough" to satisfy the user.
