5g cu du
"CU" stands for Central Unit, and "DU" stands for Distributed Unit. These are two key components of the radio access network (RAN), which is responsible for connecting mobile devices to the core network and providing wireless connectivity.
- Central Unit (CU):
- The CU is a centralized component that plays a crucial role in the 5G RAN architecture. It is responsible for the overall control and management of the radio resources within a cell or coverage area.
- The CU performs functions such as scheduling, beamforming, radio resource management, and connection establishment. It manages the communication between the user equipment (UE) and the core network.
- In terms of deployment, the CU can be located in a centralized data center, making it a part of the mobile network's cloud infrastructure. This centralized architecture allows for efficient resource utilization and easier management.
- Distributed Unit (DU):
- The DU is a distributed component that works in conjunction with the CU to provide radio access capabilities. DUs are distributed throughout the coverage area to bring the radio functionality closer to the end-users.
- DUs are responsible for tasks such as radio signal processing, modulation/demodulation, and low-level control of the radio frequency (RF) components. They handle the actual transmission and reception of radio signals to and from the user devices.
- The distributed nature of DUs allows for improved coverage, lower latency, and better support for high-density areas with a large number of connected devices.
