Keynote I: LTE on Unlicensed Band
Keynote Speaker: Prof. Geoffrey Ye Li, IEEE Fellow, Georgia Institute of Technology
Abstract: Future 5G cellular networks are facing the challenging task on increasing their capacity dramatically. Despite some cutting-edge capacity-approaching techniques, the limited licensed spectrum is still a major bottleneck for capacity improvement. To tackle this issue, a new standard has been developed within 3GPP for LTE systems, currently on the licensed bands, to operate on the unlicensed bands, which is called LTE on unlicensed bands (LTE-U). LTE has many advanced techniques, which can be exploited in the unlicensed bands to achieve a high spectral efficiency. However, the unlicensed bands are currently occupied by the widely-deployed WiFi networks.  The major challenge on LTE-U is how to design fair and efficient coexistence mechanisms between LTE and WiFi networks. In this talk, we will first discuss traditional traffic offloading, resource sharing, and hybrid of the both for LTE users to optimally exploit unlicensed bands while guaranteeing of the QoS of the existing WiFi users. To improve both the LTE and WiFi users simultaneously and achieve a win-win situation, we then provide a novel traffic offloading strategy, which is just opposite to the traditional one and offloads some WiFi users to the LTE networks and at the same time relinquishes some unlicensed bands to LTE-U. Since the unlicensed bands are usually operated less energy-efficiently than the licensed ones due to the higher carrier frequency of the unlicensed bands and larger pass-loss, we also present a framework for energy-efficiency (EE) optimization in LTE-U. We establish a criterion to determine whether the EE of the LTE system can be improved with the help of the unlicensed bands. Based on the criterion, we then develop a joint licensed and unlicensed resource allocation algorithm to maximize the EE of each LTE small cell base station.

Keynote II: Toward a User-Centric Analysis of 5G Networks
Keynote Speaker: Prof. Martin Haenggi, IEEE Fellow, University of Notre Dame
Abstract: The elements of 5G networks (base stations at different tiers, RRHs, users, etc.) are irregularly placed and thus best modeled using point processes and analyzed using tools from stochastic geometry. Many works focus on the SIR distribution at the typical user, which permits a first-order performance analysis and comparison of different architectures. However, it only describes the average performance of all links or users and thus does not reveal how concentrated the per-user SIR levels are. To capture the disparity between users, a more refined metric is needed, the so-called meta distribution of the SIR. The meta distribution is based on a clean separation of time and spatial scales and answers questions such as “what is the SIR level achieved by 95% of the users with 90% reliability?” or “what fraction of users achieve an SIR of 5 dB with 95% reliability?”. It also allows a robust definition of coverage and the calculation of the spatial outage capacity, which is the maximum density of concurrent links given an outage constraint. In this talk, we introduce and discuss the meta distribution of cellular networks with Poisson distributed base stations, for the downlink, uplink with power control, base station cooperation, and D2D underlay. For transmission modes with a high degree of diversity, an ergodic point of view is called for. For this case, we derive the distribution of the ergodic spectral efficiency over the users, which specifies the fraction of users who achieve a target spectral efficiency.
