Two-Timescale Hybrid Compression and Forward for Massive MIMO Aided C-RAN

open access: yes, 2019
We consider the uplink of a cloud radio access network (C-RAN), where massive MIMO remote radio heads (RRHs) serve as relays between users and a centralized baseband unit (BBU). Although employing massive MIMO at RRHs can improve the spectral efficiency,
