Expected Impact 1: To introduce and advance the cognitive radio application in mobile cellular networks
The capability of having high data rate along with flexibility in spectrum usage for wireless communications can be met by cognitive radio application in beyond 4G mobile wireless communications. Although cognitive radio has been discussed a lot in last years as a key technology for dynamic spectrum management within IEEE type of systems, it seems now that it could be an efficient solution for bandwidth expansion and thus improving the capacity, throughput and performance in general for next generation wireless communication systems. Given the carrier aggregation concept of LTE-A system, and the heterogeneity in RATs and networks, we believe that SOLDER provides a pervasive radio communication solution, by which all spectrum bands are aggregated without specific constraints. This dynamic spectrum scaling can be considered as the ultimate solution over next HetNets and h-RATs wireless solutions.
Expected Impact 2: Strengthened positioning of European industry in the fields of high data rate wireless mobile communications, i.e. broadband wireless access.
Carrier aggregation is a key enabling technology of beyond 4G wireless communication networks. However, the heterogeneous environment has not been taken into account and thereby SOLDER will provide this type of solution. More specifically, a new spectrum overlay technology can manage and aggregate dispersed bands of heterogeneous RATs. This technology will pave the way for the highest data rates in wireless communication systems with extreme flexibility offered by cognitive radio principles. European industry can show its strength in wireless communications providing a pervasive solution for radio communications, by which the broadband wireless access through bandwidth scaling will be achieved.
Expected Impact 3: To achieve scientific and technical excellence in terms of e.g. improved systems functionality, quality, performance and sustainability and degree of successful integration of such results into real-world scenarios.
Such a research provided by SOLDER in heterogeneous spectrum context is actually more and more crucial for the next generation systems and applications since the transformation of our society is continuously pushing technologies to become more and more pervasive and ubiquitous. However several open issues and challenges are far from solved or overcome, such as service quality, computational costs, scalability from single user to multiple users tools, synchronization, capability of discriminating among several users, the provision of personalized traffic profile services, heterogeneous networks and access technologies learning of complex and multiple interaction patterns among different entities and so on. To this end, SOLDER will achieve scientific and technical excellence in terms of improved systems functionality, quality, performance and sustainability and degree of successful integration of such results into real-world scenarios.
Expected Impact 4: To achieve high levels of scientific publication as well as new PhDs on the area of cognitive radio and broadband wireless access in heterogeneous networks.
SOLDER and its associated tasks for supporting the carrier aggregation in HetNets and h-RATs for the next generation of wireless communication systems. We believe that this will be a step forward to the direction of having next generation heterogeneous wireless and mobile broadband systems, based on flexible spectrum usage. Thus, we expect that European companies that will adopt the approaches introduced in the project will eventually enhance their services related to 5G wireless communications. Moreover, new PhD students will be supervised in a new topic that will pave the way for new research opportunities. Scientific work will be carefully carried out in SOLDER with a strong research team with experts on each part of the spectrum aggregation of heterogeneous spectrum bands.
Expected Impact 5: To impact standards with pertinent contributions in order to further the industrial harmonization and understanding of SOLDER-related technologies.
SOLDER expects to provide a number of contributions to standards in order harmonise the industrial adoption and understanding of related technologies. Particular targets include the IEEE 1900 series standards and IEEE Dynamic Spectrum Access Networks Standards Committee (DySPAN-SC) in general, as well as the likely European Telecommunications Standards Institute-Reconfigurable Radio Systems (ETSI-RRS) standards, as well as an aspiration the Third Generation Partnership Project (3GPP) LTE-Advanced standards development process although that presents a number of challenges. SOLDER will also aim to take advantage of opportunities to contribute to related IEEE 802 standards should they present themselves.
Expected Impact 6: To impact national and European policy and regulation in a way that facilitates the realisation of SOLDER aggregation technologies.
SOLDER aggregation technologies, particularly those based on opportunistic spectrum access as one example, are difficult to achieve with current regulatory rules. Such rules are often linked to policy. SOLDER aims to achieve a number of meetings with regulators and regulatory groupings in order to highlight the benefits and safe operation of SOLDER technologies under proposed minor modifications of regulatory rules. This will facilitate optimal spectrum aggregation as well as the benefits (e.g., economic) and capacity achieved through spectrum access and aggregation.
