Du Cu Preview Youtube Source: parallel wireless. the ran du sits between the ru and cu and performs real time l2 functions, baseband processing. in the o ran alliance working group, the du is proposed to support multiple layers of rus. to properly handle the digital signal processing and accelerate network traffic, fpga can be used. The distributed unit (du) handles the lower layers of the protocol stack, including data organization, management, and interaction with the radio unit (ru). it plays a crucial role in reducing latency and ensuring efficient data transmission, particularly in real time applications. what does the central unit (cu) do in the open ran architecture.

Central unit (cu): it is a logical node that includes the gnb functions like transfer of user data, mobility control, radio access network sharing, positioning, session management etc., except those functions allocated exclusively to the du. cu controls the operation of dus over front haul (fs) interface. The ultimate guide to open ran: deep dive into ru, du,. Functional splits: the foundation of an open 5g ran.
