Traffic-Driven Sounding Reference Signal Resource Allocation in (Beyond) 5G Networks

Claudio Fiandrino, Giulia Attanasio, Marco Fiore &
Beyond 5G mobile networks have to support a wide range of performance requirements and unprecedented levels of flexibility. To this end, massive MIMO is a critical technology to improve spectral efficiency and thus scale up network capacity, by increasing the number of antenna elements. This also increases the overhead of Channel State Information (CSI) estimation and obtaining accurate CSI is a fundamental problem in massive MIMO systems. In this paper, we focus on scheduling uplink...
