Visionary application scenarios, such as the Internet of Things, Gigabit Wireless Connectivity, Tactile Internet, and many more, expected to play a dominant role for 5G cellular communication systems reveal major shortcomings of the design paradigms of LTE/LTE-A, i.e. synchronism and orthogonality: 1) Collaborative schemes have been introduced to boost capacity and coverage, and wireless networks are becoming more and more heterogeneous following the non-uniform distribution of users. However, tremendous efforts must be spent to collect the gains and to manage such systems under the premise of strict synchronism and orthogonality as in LTE/LTE-A; 2) The advent of the Digital Agenda and the introduction of carrier aggregation are forcing the transmission systems to deal with fragmented spectrum. Current systems impose generous guard bands to satisfy spectral mask requirements which either severely deteriorate spectral efficiency or even prevent band usage at all, which is again an artefact of strict orthogonality and synchronism constraints within the PHY layer; 3) Finally, the fraction of machine-type-communications (MTC) is growing fast. In fact, the massive wireless connectivity of machines with other machines, referred to as M2M or the IoT, is the next foreseen killer application. Such sporadic traffic generating devices should not be forced into the bulky synchronization procedure of LTE-A PHY layer random access. In this workshop we present the state-of-the-art in the development of New Air Interfaces for 5G which efficiently support such application visions. The workshop program will discuss several new waveforms for 5G (including a scientific-oriented waveform tutorial) from an industry-driven perspective and thereby discuss design principles, implementation details, performance results, and first demonstrations of selected results. Moreover all key players in this field will present their distinctive technical viewpoint on new air interfaces and possible candidate selection. In the course of this workshop the participants will have the chance to discuss and connect with influential industry people working in this field. Altogether, it is an excellent opportunity to collect the latest views and developments regarding an exciting open field on the road towards 5G.
