Radio Combiner & Baseband Combiner in DAS

5G NR

Hi experts!

When the amount of paths exceeds the capabilities of the baseband processor, radio combiner and baseband combiner are usually used to avoid such situation. I’m confusing about the relationships among paths, cells, and the ratio of radio combiner/baseband combiner. For example, radio combiner at RHUB which is connected to 8 pRRu (4TR), can provide service to one cell with 8:1?

Is there any detailed explanation on radio combiner and baseband combiner (in 3GPP specifications)?

Hi, what do you mean with path?? can you expand a bit more. If you have pictures the better in these scenarios related to hardware.
