Title: Millimeter-wave technology trends for 5G and Wireless Transmission applications and Technologies

Wednesday, 13th September
Room: Salón de Actos, Colegio Arzobispo Fonseca


Abstract

High interest in millimeter-wave bands has risen in the recent years due to the enormous amount of under-utilized bandwidth that lies in this part of the electromagnetic spectrum. The significant advantages offered by the propagation characteristics in terms of frequency re-usability and large channel bandwidths, make millimeter-wave suitable for the very high capacities required by 5G enhanced Mobile BroadBand (10 Gpbs peak throughput and 10 Mbps/m2).

The millimeter-wave bands can be suitably used for the access networks to increase the throughput to the User Equipment and the backhaul/front-haul of the base stations. At the same time the use of millimeter-wave bands, thanks to very compact antenna size that makes products ``blend'' in the environment, allows the densification of the cells in dense urban scenarios.

This keynote will address the following topics:

  • 5G key requirements driving evolution of mobile access and wireless x-haul to millimeter-wave and sub-millimeter ranges
    • Analysis of the most important requirements of 5G to drive the trends and technology at (sub-)millimeter-wave bands for wireless backhaul / front-haul network
  • millimeter-wave access:
    • application scenarios and potential bands for 5G at millimeter-wave,
    • Massive MIMO architectures comparison
    • hybrid beam-forming architectures
    • technology challenges
  • millimeter-wave backhaul
    • how backhaul can meet the demand of capacity and network densification
    • current spectrum use, considerations on new needs deriving from mobile access moving to higher frequencies
    • new spectrum above 100 GHz and innovative ways to use it
    • millimeter-wave technical/technological trends
    • Research activities in the D-Band (130 to 175 GHz) for outdoor backhaul applications: Standardization status; Technology overview (semiconductor trends); MMIC; Antenna; Engineering solutions; Field trial registration results

From the considerations outlined so far it is relatively easy to evince the importance that the research will play in the next years in the many areas that will be necessary to cover in order to develop systems capable to operate at very high capacity with spectral efficiency, high performance, at frequencies up to 175 GHz.

Title: Network Localization and Navigation: Signal Processing Opportunities

Thursday, 14th September
Room: Salón de Actos, Colegio Arzobispo Fonseca


Abstract

The availability of positional information is of extreme importance in numerous wireless applications. The coming years will see the emergence of location-aware networks with sub-meter localization accuracy, minimal infrastructure, and high robustness in harsh (GPS challenged) environments. To reach this goal we advocate network localization and navigation, a new paradigm that exploits a combination of wideband transmission and spatiotemporal cooperation. Our work has addressed this problem from three perspectives: theoretical framework, cooperative algorithms, and network experimentation. This talk will provide an overview of our recent research results in this exciting field.

Title: Cost-, Spectrum-, and Energy-Efficient Distributed Collaborative Beamforming Designs for Real-World Applications

Friday, 15th September
Room: Salón de Actos, Colegio Arzobispo Fonseca


Abstract

Collaborative beamforming (CB), alternatively known as cooperative multi-antenna relaying, stands out today as a strong means to increase coverage, reliability, and capacity of various wireless networks by implementing through a set of terminals (sensor nodes, mobiles, network relays, soldier radios, vehicles, etc.) dual-hop transmissions between transmitter-receiver pairs when direct links would otherwise fail. Distributed CB (DCB) designs, in particular, lend themselves to distributed processing implementations that avoid the costly overhead required otherwise to broadcast the CB weights after their calculation by some master terminals. Many impediments stand, however, between the exciting concept of DCB and its real-world and wide-use applicability.

In this talk, we present novel DCB designs, obtained in closed form, that do not require any data exchange between terminals, yet properly cope, as dictated by a broad range of applications, with both scattered and interfered multi-antenna dual-hop transmissions under different power constraints. We also analyze the performance of these new DCB designs in terms of SNR and link-level throughput, both by newly established theoretical closed-form expressions and simulations to illustrate their spectrum, power, and computational-cost efficiencies in real-world operating conditions that account for various implementation imperfections.
