 CU-DU Concept and its Architecture
 CU The central unit processes some non-real-time protocols, such as packet data convergence protocol (PDCP) and radio
resource control (RRC).

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

RAN-CU function is centrally deployed in a cloudified Core

way for better DC distribution, MEC, and intelligent O&M.
