Title: Virtual User-Centric Small Cell and Cooperative Signal Transmission for 5G
Time: 10:00-10:30, Saturday, January 28, 2017
After 35 years from its birth in 1979, wireless mobile communications networks have evolved into 4G. The mobile data traffic volume in 2020 is expected to reach about 1000 times of 2010. Therefore, the spectrum-efficiency is becoming more and more important for 5G. Furthermore, the energy-efficiency will become an important concern. To improve both the spectrum-efficiency and energy-efficiency, mobile communications networks need to be significantly restructured. A promising solution is to introduce small-cell structured networks in order to exploit more the spatial distribution of users. In this talk, we will introduce a virtual user-centric small-cell concept. Then, we will present the recent advances in distributed antenna cooperative signal transmission techniques: the space-time block-coded diversity for improving the signal quality for macro-cell edge users and the spatial multiplexing for improving the sum capacity of users in a good propagation condition. Since higher frequency bands will be used in 5G, the transmit signal peak-to-average power ratio (PAPR) remains as an important concern for power amplifiers of battery operated user terminals. In this talk, PAPR reduction technique will also be presented.

Title: Beamformer Design for Massive MIMO Systems in Millimeter-Wave Channels
Time: 14:00-14:30, Saturday, January 28, 2017
We establish a general framework on the reduced dimensional channel state information (CSI) estimation and pre-beamformer design for frequency-selective massive multiple-input multiple-output (MIMO) systems employing single-carrier (SC) modulation in time division duplex (TDD) mode by exploiting the joint angle-delay domain channel sparsity in millimeter (mm) wave frequencies. First, based on a generic subspace projection taking the joint angle-delay power profile and user-grouping into account, the reduced-rank minimum mean square error (RR-MMSE) instantaneous CSI estimator is derived for spatially correlated wideband MIMO channels. Second, the statistical pre-beamformer design is considered for frequency-selective SC massive MIMO channels. We examine the dimension reduction problem and subspace (beamspace) construction on which the RR-MMSE estimation can be realized as accurately as possible. Finally, a spatio-temporal domain correlator-type reduced-rank channel estimator, as an approximation of the RR-MMSE estimate, is obtained by carrying out least square (LS) estimation in a proper reduced dimensional beamspace. It is observed that the proposed techniques show remarkable robustness to the pilot interference (or contamination) with a significant reduction in pilot overhead.

Title: On the Use of Network Coding to Realize Proactive Shared Backup Path Protection in Optical Networks
Time: 15:00-15:30, Saturday, January 28, 2017
Optical fibers carry large amounts of bandwidth, which is on the order of multiple Terabits/sec. The failure of any of these fibers, e.g., due to a cut or due to equipment failures, can result in disruption of service, which affects large numbers of network users. Therefore, providing resilience to failures and protection against the effect of such failures in optical networks is very important in order to guarantee non-stop service, or service with the least amount of disruption. To provide this protection against failures, many techniques have been developed. Shared Backup Path Protection (SBPP) is known to be the protection strategy that requires the least amount of protection resources. However, SBPP is a reactive strategy, which requires detecting failures, signaling and reconfiguring switches. This talk introduces a new definition of network coding, and shows how this can be applied to implement Shared Backup Path Protection (SBPP) in a proactive manner. We describe the new network coding definition, and propose a implementing proactive SBPP, using this definition, in optical networks and using optical devices. We will explain the merit of this approach in terms of agility and cost, and compare it to other well known protection approaches.

Title: Deep Reinforcement Learning for Dynamic Multichannel Access
Time: 15:00-15:30, Saturday, January 28, 2017
We consider the problem of dynamic multichannel access in a Wireless Sensor Network (WSN) containing $N$ correlated channels, where the states of these channels follow a joint Markov model. A user at each time slot selects a channel to transmit a packet, and receives a reward based on the success or failure of the transmission, which is dictated by the state of the selected channel. The objective is to find a policy that maximizes the expected long-term reward. The problem can be formulated as a partially observable Markov decision process (POMDP), which is PSPACE-hard and intractable. As a solution, we apply the concept of online learning and implement a Deep Q Network (DQN) that can deal with large system space without any prior knowledge of the system dynamics. We compare the performance of DQN with a myopic policy and a Whittle Index-based heuristic through simulations and show that DQN can achieve near-optimal performance. We also evaluate the performance of DQN on traces obtained from a real indoor WSN deployment. We show that DQN has the capability to learn a good policy in complex real scenarios, which do not necessarily show Markovian dynamics.

Title: AI, Native Supercomputing and the Revival of Moore's Law
Time: 11:00-11:30, Friday, January 27, 2017
Moore’s Law needs a new computing paradigm to motivate and revive the historic exponential performance scaling while AI as a new computing paradigm requires exponentially more capable hardware from Moore’s Law to prevail. For Moore’s Law, the exponential performance scaling with clock speed ended in 2005, and the one with core count, or parallelism, has not happened. We cannot fit exponentially more cores on a chip due to the lagging progress in power efficiency per core and the growing gap between logic and DRAM. Under the von Neumann architecture, the current dominant computing paradigm, a computing core has to carry architecture legacy for software compatibility, and use big on-chip memory to overcome the logic-DRAM gap. It cannot be aggressively specialized to improve power efficiency. In addition, performance scaling with parallelism works only for workloads scalable in problem size, which is not necessarily true for computing problems in general. AI is decoupled from von Neumann architecture thru Deep Learning. It consolidates computing problems into scalable number crunching dominated by math primitives, the language of Supercomputing. Bigger training data generally lead to bigger networks and better user experience, which, in turn, motivate further investment in Moore’s Law for more cores on a chip. AI allows the cores to be specialized to handle math primitives natively and fed with interconnect optimized for native data movement patterns. Such hardware optimizations can be isolated from software thru math library interface. Programmers do not need to worry about parallelism, and they should expect better performance or solve bigger problems on hardware with more cores.

Title: Mesh Networking in 5G
Time: 14:00-14:30, Saturday, January 28, 2017
The benefits of relaying are well understood in network information theory. In 5G systems, relaying techniques can make a practical impact by enabling wireless backhaul at high frequencies, massive machine-type-communications and device-to-device communications. In relay networks, noisy network coding (NNC) achieves the best known performance and achieves a constant gap from the network capacity. However, this gap may not be negligible in 5G multihop applications. Furthermore, the implementation of NNC is challenging. I will present a NNC scheme that overcomes these problems. The proposed scheme outperforms the existing state-of-the art relaying schemes with lower complexity and lower delay, and can thereby lead to practical solutions for 5G mesh networking. (Based on joint work with Song-Nam Hong, Dennis Hui and Giuseppe Caire.)

Title: Unmanned Aerial Vehicle Networking for Wide-Area Deployment
Time: 14:30-15:00, Saturday, January 28, 2017
Cooperation and collaboration of multiple unmanned aerial vehicles (UAVs) are useful and promising in various applications, especially when their missions are operated in wide areas. Focusing on disaster-affected area surveillance and distribution service, system architectures and service scenarios of UAV networking are examined, allowing wide area deployment. In the former, a wide disaster area is divided into a number of subareas, and one UAV is assigned in each subarea for performing surveillance from the air. Electric vehicles (EVs) are used to support transport, automatic piloting, and energy supply for UAVs. The surveillance data obtained by each UAV is delivered to a data collection point in the area via wireless multihop communication through EVs and UAVs. In the latter, a number of package destinations are distributed in a wide area. Each UAV is in charge of delivering packages for a given set of destinations. In principle a UAV perform delivery only to one destination at a time, taking the most efficient route. Power-supply stations may be deployed along the routes for extending the cruising range of UAVs. Uniform distribution job assignment among multiple UAVs is considered on the basis of square-area modeling. Discussions are made on the benefits of mobile ad hoc networking among UAVs in these applications and services.

Title: Coded Content Caching: A New Paradigm for Wireless Cellular Networks
Time: 13:30-14:00, Saturday, January 28, 2017
Recent advances in storage technology have made it possible for many consumer and user products with Terabyte of storage capability. Many researchers are investigating the possibility of taking advantage of this under-utilized storage capability to cache popular contents in order to improve the content delivery in wireless cellular networks. The main idea behind caching is to replicate a content inside the network and as much as possible close to the end users and all the research results are based on storing uncoded contents either entirely or partially during cache placement phase. The information theoretic study of caching focuses on broadcast channel.
In this talk, we introduce a radically different cache placement approach. We propose to cache decentralized coded content caching with a focus on wireless Device-to-Device (D2D) communications. Comparison with uncoded content caching demonstrates significant capacity gains. The extension of the work to wireless ad hoc networks, its impact on routing protocols and security aspects will be discussed.

Title: Using SDN to Deliver Quality of Experience for Multimedia Services
Time: 17:30-18:00, Saturday, January 28, 2017
Multimedia services such as video streaming, gaming, and tele-conferencing now constitute more than 70% of Internet traffic. While these services have strict quality requirements, service providers have been unable to meet them, due to the best-effort nature of the Internet, which gives service providers very little control on how to handle flows for multimedia streams. Software Defined Networking (SDN) has the potential to give greater control to providers, enabling them to offer better quality services. In this talk, we will first present the different classes of multimedia services and the quality of experience that their users expect. We will then describe how SDN can help providers to support the different classes of these services more efficiently, leading to higher quality of experience for the consumers. We will also study a few specific cases of SDN-enabled multimedia services for video-on-demand, and cloud gaming.

Title: Technology and Architectural Approaches to Address Continued Explosive Growth in Network Traffic
Time: 13:30-14:00, Saturday, January 28, 2017
Continued explosive network traffic growth dictates that network capacity grow accordingly. Moreover, it is highly desirable that the increase in network capacity be accompanied by a decrease in cost and power consumption per unit of bandwidth. Simply lighting up additional network fiber will not meet this goal, thus motivating research into more efficient solutions. We discuss technologies that potentially deliver the required growth in capacity along with the desired cost and power economies-of-scale. While these approaches hold promise, they present various challenges and drawbacks, including adding complexity to network design, and are not likely to be deployed in the very near future. An alternative, though much more limited, means of handling greater traffic demand is through more efficient use of existing capacity. We enumerate a variety of architectural approaches that fall under this umbrella. While not providing benefits commensurate to those of the technological approaches, they represent feasible near-term solutions. Ultimately, a combination of methodologies is likely to be deployed, such that capacity can continue to gracefully scale as needed.

General Manager, TCL Research America, USA
Title: Future Mobile World without Apps
Time: 10:30-11:00, Friday, January 27, 2017
This talk will present a vision of the future where apps are no longer the dominant customer interaction in the mobile world. The alternative that we propose would "orchestrate" the mobile experience by using a "moment-first" model that would leverage machine learning and data mining to bridge a user's needs across app boundaries, matching context and knowledge of the user with ideal services and interaction models between the user and device. In this way, apps would be employed at a function level, while the overall user experience would be optimized by liberating user data outside of the app container and intelligently orchestrating the user experience to fulfill the needs of the moment.

Title: Challenges in Networking to Support Augmented Reality and Virtual Reality
Time: 17:00-17:30, Saturday, January 28, 2017
We consider the network implications of virtual reality (VR) and augmented reality (AR). While there are intrinsic challenges for AR/VR applications to deliver on their promise, their impact on the underlying infrastructure will be undeniable. We look at augmented and virtual reality and consider a few use cases where they could be deployed. These use cases define a set of requirements for the underlying network. We take a brief look at potential network architectures. We then make the case for Information-centric networks as a potential architecture to assist the deployment of AR/VR and draw a list of challenges and future research directions for next generation networks to better support AR/VR.
