Radio Unit

CU The central unit processes some non-real-time protocols, such as packet data convergence protocol (PDCP) and radioresource control (RRC).

DU The distributed boards process real-time services, including scheduling, paging, broadcast, *RLC/MAC/PHY, and eX2/CUDUinterface management.

About F1 Interface

CloudRAN CU/DU split would allowed CU to be centralized.

The transmission requirement of the F1 interface is equivalent to S1 interface
