Joint Fronthaul and Multicast Beamforming for Ultra-Dense C-RANs

This work investigates multicast transmission in ultra-dense cloud radio access networks (C-RANs) with wireless fronthaul. To maximize the weighted sum rate (WSR) of multicast services, joint beamforming for fronthaul and access links are designed, subject to the constraints of fronthaul capacity an...
