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...
This paper presents an application of cognitive radio system concepts for the off-loading operation of LTE networks by the opportunistic use of TV whitespace (TVWS). A flexible functional architecture based on two cognitive managers for spectrum management and resource management respectively, and developed for various mobile scenarios, is mapped to the LTE network architecture. Corresponding system...
The realization of cognitive radio networks is a key solution to meet the raising expectations for high data rates and quality of service in mobile communications. This implies the design of a two-fold cognitive manager for resource management (CM-RM), to manage an opportunistic use of the whitespaces as introduced in this paper, and for Spectrum Management (CM-SM). The proposed CM-RM has been designed...
Optimizing the Quality of Service (QoS) support, providing seamless mobility and ensuring the protection of incumbent users are some of the challenges that arise when the radio spectrum is accessed in an opportunistic way. The functional concept of Cognitive Resource Manager (CRM) is presented providing cognition of the environment to optimize the allocation and exploitation of radio resources, to...
Mobile communication systems are facing an increasing demand for higher bit rates and reveal a growing heterogeneity and complexity. The European funded End-to-End Efficiency (E3) project has developed a system concept for cognitive and self-managed adaptation of radio network resource usage to dynamic user traffic and service demands. The main features of that E3 concept for cognitive wireless systems...
