The 5G RAN architecture allows for a range of deployment options, supporting a range of 5G services. There are multiple options on functional split (how the RAN can be disaggregated into distributed and centralised components), which offer different trade-offs. As the industry progresses, we are starting to understand more details about these trade-offs. This document aims to provide latest updates on the functional split options that might be considered for 5G, and provide insight into how these splits might be deployed
The 5G RAN has two main functional splits options: high layer split (HLS) and low layer split (LLS). HLS is the more mature solution and we provide recent updates from industry activities, describe examples for transport dimensioning, and also address security considerations. LLS is developing fast with specifications now published. We provide an overview of recent
industry activities on LLS, and examples of transport dimensioning which show significantly improved performance in comparison to compressed CPRI. 429432507-5G-RAN-CU-DU-Network-Architecture.pdf(2.23 MB, 下载次数: 23)
