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.

IEEE GLOBECOM is one of two flagship conferences of the IEEE Communications Society, together with IEEE ICC. Each year the conference attracts about 3000 submitted scientific papers. A technical program committee of more than 1,500 experts provides more than 10,000 reviews, and from this a small fraction of the submitted papers are accepted for publication and presentation at the conference. The conference meets once a year in North America and attracts roughly 2000 leading scientists and researchers and industry leaders from all around the world. IEEE GLOBECOM is therefore one of the most significant scientific events of the networking and communications community, a must-attend event for scientists and researchers from industry and academia.

IEEE GLOBECOM is a five-day event. Two days are dedicated to tutorials and workshops, while the remaiing three days are dedicated to the IF&E program and the technical symposia. The program of the technical symposia includes oral or poster presentations of about 1000 scientific papers, grouped into 12 thematic symposia, and more than 15 parallel sessions. In addition to the technical program, IEEE GLOBECOM 2014 will feature an industry forum and exhibition (IF&E) program, including industry-focused workshops, tutorials, keynote talks from industrial leaders, panel discussions, a large exposition, and business and industrial forums.

For more information, please check the official IEEE Globecom 2014 conference website.
