Why 16harq processes in 5G? why not 32 or 64?

number of harq process are 8 in lte and 16 in NR.
why specifically 16 only why not 32?

Hi @pratik.shedge!

I suppose increased number of HARQ process are related to increased requirements for Throughput and Reliability.

More parallels process allows to us increase those KPIs.

Yes, that is correct.
However, my question is why 16? why not 32 or 64 ?
what criteria/kpi is taken into consideration to come up with 16?
