摘要:
Functions of base station (BS) can be separated into a central unit control plane (CU-CP) for control plane functions, central unit user plane (CU-UP) for user plane functions and a distribution unit (DU) for user equipment communication functions. For example, the control plane (CP) of a base station is split, centralizing part of the CP in a Central Unit (CU). The user plane (UP) of the air interface is partitioned and part of the UP of the air interface and UP of the backhaul is centralized in a CU that can be co-located with the CU hosting the CP, or in a different location, while leaving the rest of the UP of the air interface distributed. Control plane/user plane (C/U) separation, user-plane partitioning and modular design can improve latency and/or bandwidth of interfaces, mobility among BS's, flexible deployment of RAN functions, and the virtualization of the CP and/or the UP.
