Abstract Uplink and downlink cloud radio access networks are modeled as two-hop K-user L-relay networks, whereby small base-stations act as relays and are connected to a central processor via orthogonal fronthaul links of finite capacities. Based on noisy network coding and distributed decode–forward inner bounds on the capacity regions for uplink and downlink, respectively, the total fronthaul link capacity required to approach the centralized MIMO sum rate is characterized. The capacity scaling law when the network size increases is examined under certain uplink and downlink network models, both theoretically and via simulations.
