Thanks, was it a live trial? It is hard to meet the condition of more than 200 RRC users connected in 5G in 2017… You probably saw 16 layers recently, not in 2017. Was it in live network or trial again?
Also I don’t understand why gain from 8DL to 16DL is just 20%. It all depends on users location, as close as possible to gNodeB or not. With 8DL layers users can be more distanced from the gNodeB compared to 16layers requirement that would require users really close to gNodeB so we are not comparing apples to apples.
Don’t know which vendor advertised 24 DL layers. The gain for each beamforming of those 24 layers would be really low and would not worth the feature investment unless it increases the AAUs elements from 64 to 128/256/512. I doubt somebody would replace the AAUs just for this. There is no buy-back in this business.
Thank you.
