Title
Technology and Policy for Millimeterwave 5G and Backhaul
Abstract
As recently as the early 1980s it was generally thought that mobile radio systems above 1 GHz were not practical. With rapidly escalating demand for mobile radio capacity to serve new applications such as smartphones and new wireless technologies, there is now interest in possible mobile wireless systems up to 100 GHz. Such millimeterwave (mmW) system could provide much higher speed and lower latencies than lower bands due to spectrum bandwidths that are significantly greater. These high speed mobile systems will also require large capacity backhaul systems to interconnect base stations. While optical fiber systems are generally cost-effective for such uses based on hardware costs, in urban areas where installed fiber is not available installation costs of fiber can dwarf material costs. Fortunately, the same basic mmW technology can also be used for backhaul and other Fixed Service applications. A key question is how readily spectrum can be shared between mobile and fixed stations in the same area. The small wavelengths at mmW bands allow modest size antennas with small beamwidths to isolate nearby mobile and fixed use and other isolation techniques may also be possible. Much of today’s national and international policy concepts for spectrum regulation date to the Titanic sinking in 1912. The mmW bands have technical characteristics very different than both the bands in use then and most of the bands in use now. Thus some generally accepted traditional concepts of spectrum policy may have to be revalidated or reconsidered for the mmW case in order to use this new spectrum resource productively for all possible users, including both active systems and passive systems.
Short Biography
Michael Marcus is a native of Boston and received S.B. and Sc.D. degrees in electrical engineering from MIT. Prior to joining the FCC in 1979, he worked at Bell Labs on the theory of telephone switching, served in the U.S. Air Force where he was involved in underground nuclear test detection research, and analyzed electronic warfare issues at the Institute for Defense Analyses.
At FCC his work focused on proposing and developing policies for cutting edge radio technologies such as spread spectrum/CDMA and millimeterwaves. Wi-Fi is one outcome of his early leadership. The total amount of spectrum he proposed for unlicensed use and directed the drafting of implementing rules was 8.234 GHz. He also participated in complex spectrum sharing policy formulation involving rulemakings such as ultrawideband and MVDDS. Awarded a Mike Mansfield Fellowship in 1997, he studied the Japanese language and spent at year at the FCC’s Japanese counterpart.
He retired from FCC in March 2004 after servicing a senior technical advisor to the Spectrum Policy Task Force and codirecting the preparation of the FCC’s cognitive radio rulemaking. Immediately after retirement he lived in Paris France for 3 years, consulting for US and European clients. In 2006 he was appointed Special Advisor to Mrs. Viviane Reding, European Commissioner for Information Society & Media.
He is now Director of Marcus Spectrum Solutions LLC, an independent consulting firm based in the Washington DC area and focusing on wireless technology and policy. He is also Adjunct Professor of Electrical and Computer Engineering at Virginia Tech and the 2011-2013 chair of the IEEE-USA Committee on Communications Policy. He was recognized as a Fellow of the IEEE “for leadership in the development of spectrum management policies”, received in 1994 IEEE-USA’s first Electrotechnology Transfer Award , and received in 2013 the IEEE ComSoc Award for Public Service in the Field of Telecommunications "For pioneering spectrum policy initiatives that created modern unlicensed spectrum bands for applications that have changed our world."

Title
Cognitive Radio Networks: Design Challenges and Potential Solutions
Abstract
Exponential growth in mobile data traffic due to extensive uses of smartphones and tablets has created tremendous traffic burden on existing telecommunications infrastructure. Although significant efforts have already been made on spectrum efficiency by developing various innovative transmission technologies, hurdles cannot be jump over easily due to the physical transmission constraints. Cognitive radio technology is envisioned to unleash under-utilized licensed spectra and opportunistically utilize them to support communications services without affecting the incumbent spectrum users. Unfortunately, most research focuses on either cognitive radio design or spectrum sensing mostly for one-hop communications, which cannot address end-to-end services effectively. In this talk, the speaker will discuss design challenges in cognitive radio networks and then present a network solution for effective spectrum harvesting and optimization, leading to a collaborative design approach. This design not only enables network operators to tap unused (licensed/unlicensed) bands opportunistically and effectively, but also offers other optional strategies for significant network performance gain.

Title
Towards Harmonization: Interference Coordination inHeterogeneous Cellular Networks
Abstract
With the rapid growth in use of wireless devices such as smart phones, laptops, and tablets, the population of mobile users using the wireless cellular infrastructure for Internet connectivity are increasing dramatically. The traditional homogeneous network with cell splitting cannot accommodate the rapid growth of user population and the associated big data. The architecture of cellular networks is now entering a new phase where the dense deployment of access points can effectively increase the spatial reuse of scarce radio resources to accommodate the exponentially growing mobile data traffic. Heterogeneous cellular network is a new wireless communications paradigm that advocates base station “densification” and promotes “multi-tier cells” concept that allows heterogeneous wireless networks, e.g., macro-cells and micro-cells, to co-exist in the same geographic area and share licensed frequency band with unlicensed users. Whilst heterogeneous network users could be served simultaneously, interference and spectrum congestion due to the network co-existence may severely limit the potential benefits and use of the new communications paradigm. This talk will present research advances in interference coordination techniques for future generation cellular networks. Along with an overview of interference management techniques, this talk will focus on the design of practical interference coordination schemes based on beamforming and user scheduling. The proposed schemes aim to deal with the inter-cell interference in multi-cell MIMO networks, inter-tier interference in device-to-device (D2D) communications underlaying cellular network, and inter-system interference in cognitive radio networks. The performances of the proposed schemes are evaluated both analytically and numerically in terms of sum rate, multiplexing gain, and outage probability of the networks. The results show that the proposed schemes can significantly reduce the effect of interference and improve the overall capacity of the future generation cellular networks.

Advanced Spectrum Sharing for 5G and Future Cellular Networks
Abstract
The 5G and future cellular networks are expected to support the explosive growth of mobile data for various types of services. Besides increasing the spectral efficiency and exploring unused spectrum, the need for spectrum sharing to support the deployment of various networks becomes unavoidable. Over the past decade, there have been a lot of research and development activities devoted to the spectrum sharing research. In this talk, I will highlight the key cognitive radio ideas and technologies that could contribute to the development of 5G and future cellular networks, including, e.g., spectrum refarming, LTE-U, D2D communications, and software-defined wireless network access.
