In this paper, an initial vision of what the sixth generation mobile communication system (6G) might be is presented. This is done through the primary ideas of the 6Genesis Flagship Program (6GFP), a recently formed Finnish academic and industrial consortium aiming at developing key enabling technologies for 6G. 6GFP is an eight-year large-scale research initiative set to ultimately develop, implement and test key enabling technologies for 6G. Motivations, visions, trends and expectations for 6G are first discussed to set the ground for further development. Four main research areas are proposed as the starting point, encompassing not only wireless communications but also computer science, electronics and material science as well as applications and services. The paper provides an in-detail list of technical topics going to be studied in this program, and in general, worth considering for everyone planning to develop beyond 5G technology. The paper also shed some light on how the research will be implemented, showing the logic and relationships between the research areas, discussing already selected promising enabling technology for 6G, as well as envisioning how the proof-of-concept of the developed system will be carried out. An existing state-of-theart 5G network will be used as the starting point for developing and testing the novel concepts and technologies created in the program (Abstract)

This article advocates a novel communication architecture and associated collaborative framework for future wireless communication systems. In contrast to the dominating cellular architecture and the upcoming peer-to-peer architecture, the new approach envisions a cellular controlled short-range communication network among cooperating mobile and wireless devices. The role of the mobile device will change, from being an agnostic entity in respect to the surrounding world to a cognitive device. This cognitive device is capable of being aware of the neighboring devices as well as on the possibility to establish cooperation with them. The novel architecture together with several possible cooperative strategies will bring clear benefits for the network and service providers, mobile device manufacturers and also end users.

SUMMARYMany production Grid and e-Science infrastructures have begun to offer services to end-users during the past several years with an increasing number of scientific applications that require access to a wide variety of resources and services in multiple Grids. Therefore, the Grid Interoperation Now-Community Group of the Open Grid Forum-organizes and manages interoperation efforts among those production Grid infrastructures to reach the goal of a world-wide Grid vision on a technical level in the near future. This contribution highlights fundamental approaches of the group and discusses open standards in the context of production e-Science infrastructures.
