C-RAN - BBU Pool implementations

[antonioli]

Hi all,

I'm looking for information about practical examples of implementation of BBU Pool in C-RAN.
So far only found only academical documents or vendor documentation about the concept. Telco operators are implementing it?

I work as OSS Consultant and my goal is to prepare some scenarios at Resource Inventory level. In very high level BBU Pool is just an "aggregation" or a "logical grouping" of BBU - but how it works in terms of implementation - how vendors like Hua, Nokia or E/// are implementing it at configuration level?
