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.
5g Nr Protocol Structure Changes An Overview 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). where to split between cu and du ?. The o du high scans the list of cells received and sends corresponding cell configurations to 5g nr mac. 5g nr mac, in turn configures the 5g nr sch. it also configures the o du low via the lower mac module. on receiving the cell config response, du app sends a gnb du config update towards the o cu. On apr 9, 2021. as the 5g ran architecture progresses and the ran splits between the cu and du, i am wondering if you would like to add in open5gs also the 5g cu cp and cu up functions. the 5g cu cp will expose the f1 ap protocol (according to 3gpp 38.473) towards a du. the 5g cu up will expose the f1 u gtp tunnel towards a du. The srsran project is a complete 5g ran solution, featuring an oran native cu du developed by srs. the solution includes a complete l1 2 3 implementation with minimal external dependencies. portable across processor architectures, the software has been optimized for x86 and arm. srsran follows the 3gpp 5g system architecture implementing the functional splits between distributed unit (du) and.

After extensive discussions, 3gpp defined two 5g nr split architectures in addition to the traditional monolithic one: option 2 – a high level centralized unit (cu) and distributed unit (du) split which is primarily a separated control and user plane. option 7 (or 7.2) – a low level split for ultra reliable low latency communication (urllc. Figure 3 – a generic example 5g ran with multi tier aggregation. blue shapes indicate locations of possible compute capability to support ran functions (e.g., du and or cu) [1] an overview of some of the key transport options that may be used as part of the 5g access network is provided below.
