Query: Control-Data Separation across Edge and Cloud for Uplink Communications
  in C-RAN   Fronthaul limitations in terms of capacity and latency motivate the growing
interest in the wireless industry for the study of alternative functional
splits between cloud and edge nodes in Cloud Radio Access Network (C-RAN). This
work contributes to this line of work by investigating the optimal functional
split of control and data plane functionalities at the edge nodes and at the
Remote Cloud Center (RCC) as a function of the fronthaul latency. The model
under study consists of a two-user time-varying uplink channel in which the RCC
has global but delayed channel state information (CSI) due to fronthaul
latency, while edge nodes have local but timely CSI. Adopting the adaptive
sum-rate as the performance criterion, functional splits whereby the control
functionality of rate selection and the decoding of the data-plane frames are
carried out at either the edge nodes or at the RCC are compared through
analysis and numerical results.
