Rel 15 Ng Ran Architecture With A Cu Du Split Deployment Download Distributed unit (du): this logical node includes a subset of the gnb functions, depending on the functional split option. 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. 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.
Reason For Cu Du Split Architecture Among all of these differences, out of the most outstanding one would be that the gnb internal structure is split into two parts called cu (central unit) and du (distributed unit) as shown below and these two entities are connected by a new interface called f1 (for the details of f1 intreface, refer to 38.473). 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. Ieee 1914 ngfi (next generation fronthaul interface) wg continues their efforts in the ngfi standards development. in particular, the p1914.1 tf has developed a stable draft and begun its 3rd round of wg level review process. in the stable draft, the ngfi network requirements are developed from two dimensions. The cu du interface configurations. a functional split between the mac and phy layer or withing the phy layer itself can improve radio performance through advanced inter cell coordination including the mac scheduler. the transmission network used here for the front haul would satisfy high requirements for latency.
