Fraunhofer Heinrich-Hertz-Institut (HHI) located in Berlin brings innovation to the field of communication technology since 1928; since 2002 it belongs to the Fraunhofer alliance. Traditionally, it has strong bonds to industry and supports directly and indirectly standardization; 30% of total budget are industry contracts. The core competencies of HHI are in the areas of Photonic Networks and Systems, Mobile Broadband Systems, Photonic Components and Electronic Imaging. HHI’s mission is to develop communication technology intellectual property and practical solutions which have major impact to the world of information and communication.
Fraunhofer HHI’s Wireless Communication and Networks (WN) department develops solutions within the entire range of mobile broadband networks and systems ranging from information theory via channel measurement, design of detection algorithms, system- and network simulation right through to the implementation of algorithms in demonstrators. Special emphasis is put on interference management, cross-layer optimization, cognitive radio, multi-antenna systems, self-organization and self-optimization, heterogeneous access management, cooperative systems, distributed wireless networks including wireless sensor networks.
5th Generation Non-Orthogonal Waveforms for Asynchronous Signalling is the evolution of mobile communication network technology such as LTE-Advanced toward emerging application challenges like the Internet of Things, the Digital Agenda and Heterogeneous Networks.
LTE and LTE-Advanced have been optimized to deliver high bandwidth pipes to wireless users. The transport mechanisms have been tailored to maximize single cell performance by enforcing strict synchronism and orthogonality within a single cell and within a single contiguous frequency band. Various emerging trends reveal major shortcomings of those design criteria:
- The fraction of machine-type-communications (MTC) is growing fast. Transmissions of this kind are suffering from the bulky procedures necessary to ensure strict synchronism.
- Collaborative schemes have been introduced to boost capacity and coverage (CoMP), and wireless networks are becoming more and more heterogeneous following the non-uniform distribution of users. Tremendous efforts must be spent to collect the gains and to manage such systems under the premise of strict synchronism and orthogonality.
- The advent of the Digital Agenda and the introduction of carrier aggregation are forcing the transmission systems to deal with fragmented spectrum.
5GNOW will question the design targets of LTE and LTE-Advanced having these shortcomings in mind. The obedience of LTE and LTE-Advanced to strict synchronism and orthogonality will be challenged. 5GNOW will develop new PHY and MAC layer concepts being better suited to meet the upcoming needs with respect to service variety and heterogeneous transmission setups. A demonstrator will be built as Proof-of-Concept. 5GNOW will build upon continuously growing capabilities of silicon based processing.
Wireless transmission networks following the outcomes of 5GNOW will be better suited to meet the manifoldness of services, device classes and transmission setups being present in envisioned future scenarios like smart cities. The integration of systems relying heavily on MTC, e.g. sensor networks, into the communication network will be eased. The per-user experience will be more uniform and satisfying. To ensure this 5GNOW will contribute to upcoming 5G standardization.
