EECS Seminar: A Theoretical Model for Information Flow and Scheduling in mmWave Networks

Abstract: Millimeter-Wave (mmWave) communications are expected to play a vital role in 5G mobile communications and beyond, expanding the available spectrum and enabling multi-gigabit services such as next-generation business solutions, virtual and augmented reality applications, and autonomous vehicle and drone communication. Although for single-hop mmWave networks, several works have examined channel modeling, performance bounds and algorithms, for multi-hop mmWave networks, fundamental performance bounds such as the information-theoretical capacity have not been well explored. 

In this talk, we will discuss a simple yet informative theoretical model for multi-hop mmWave networks called 1-2-1 networks. In such networks, the ineffectiveness of isotropic transmission is captured by assuming that two nodes can communicate only if they point beams at each other, otherwise, the signal is received well below the thermal noise level. The focus of the talk will be to highlight the operational benefits that arise from the beamforming nature in our model for mmWave networks, as well as the complexities that accompany the need to use and steer such beamforming. 

Time permitting, we will discuss some additional wireless communication network applications from the viewpoint of designing low-complexity algorithms that can achieve provable performance guarantees.

This talk is based on joint work with Martina Cardone, Christina Fragouli and Giuseppe Caire.
