Centralized Unit вђ Distributed Unit Cu Du Split Baseођ Distributed unit (du) provides support for lower layers of the protocol stack. there can be multiple du connected to each centralized unit (cu). as an example there can be more than 100 distributed units connected to a specific centralized unit. distributed unit (du) includes both baseband processing and rf functions. Its operation is controlled by the cu. distributed unit (du) also known with other names like rrh rru re ru. the cu du split options: central unit (cu) and distributed unit (du) functional split options. as a part of study item for new radio (nr), 3gpp started studying different functional splits between central and distributed units.
Example Of Distributed Unit Du And Central Unit Cu Placement In The cu du (centralized unit distributed unit) separation is a concept related to the architecture of 5g networks. it represents a shift from the traditional architecture where the baseband processing is performed within the base station to a new architecture where the baseband processing can be split into two parts: the cu and the du. Distributed unit (du): the du is responsible for the lower layer processing of the radio signals. it performs functions such as modulation, coding, and decoding of the radio signals. similar to the cu, the du is also divided into two subcomponents: the distributed unit centralized (du cp) and the distributed unit distributed (du up). 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. In release 15, 3gpp, defined a new, flexible architecture for the 5g ran, where the base station or gnodeb (gnb) is split into three logical nodes: the central unit, (cu), the distributed unit, (du) and the radio unit, (ru), each capable of hosting different functions of the 5g nr stack. figure 1 shows the baseband unit (bbu) — a proprietary.

Let's delve into the technical details of the distributed unit in 5g: 1. definition and role: distributed unit (du): in 5g, the du is a functional element responsible for radio processing and control. it is part of the centralized unit (cu) distributed unit (du) split architecture, where the cu and du work together to enable radio access and. The 5g radio base station, known as next generation node b (gnb) is split into two entities: a gnb distributed unit (gnb du (often shortened to du)) and a gnb centralized unit (gnb cu (often shortened to cu)). 5g ran functional blocks and interfaces ran split protocol architecture. 3gpp used the ran protocol model as per below figure (3gpp tr.
