1. Central Unit (CU):
   • The Central Unit is a key component in the 5G radio access network (RAN) architecture.
   • It performs the centralized processing functions for multiple Distributed Units (DUs).
   • The CU is responsible for functions such as radio resource management, mobility management, and connection establishment.
   • It communicates with the DUs to coordinate and control the overall radio access network.
2. Distributed Unit (DU):
   • The Distributed Unit is another crucial element in the 5G RAN architecture.
   • DUs are distributed across the network to bring processing closer to the edge, reducing latency and improving efficiency.
   • They handle baseband processing, which involves functions like modulation, coding, and other signal processing tasks.
   • DUs connect to multiple RUs (Radio Units) and communicate with the Central Unit to coordinate and manage resources.
3. Radio Unit (RU):
   • The Radio Unit is responsible for the actual radio transmission and reception of signals.
   • It handles the analog and RF (Radio Frequency) processing of signals.
   • RUs are typically located at or near the antenna site (base station) and are responsible for converting digital signals into analog signals for transmission over the airwaves and vice versa.
   • RUs are connected to DUs, and the DUs coordinate and manage multiple RUs.

Now, let's discuss how these components work together in a 5G network:

• The CU is responsible for the overall coordination and management of the RAN. It communicates with multiple DUs to ensure efficient resource allocation and management.
• DUs are distributed across the network, close to the antennas and RUs. They perform baseband processing tasks and communicate with both the CU and RUs.
• RUs handle the radio transmission and reception tasks, converting digital signals into analog signals for wireless transmission.
