In the context of 5G, the Central Unit is typically part of the Radio Access Network (RAN) architecture. The CU is responsible for controlling multiple Distributed Units (DUs) and managing radio resources. It plays a crucial role in scheduling and managing connections to User Equipment (UE) in a mobile network.
DU (Distributed Unit):
The Distributed Unit in a 5G network is responsible for handling the radio transmission and reception. DUs are distributed throughout the network and are connected to the CU. They handle the actual data transmission between the user equipment (UE) and the network. DUs are more distributed compared to previous generations of mobile networks, allowing for flexibility and improved performance.
