How ENB decides the size of Group A and Group B?

Question

How ENB decides size of GroupA , GroupB and contention free preambles. based on what basis ENB decides this information?

Answer 1

Hi,

Good question. we have two groups, group A and group B. I assume this means in practise that the preamble group chosen by the UE indicates to the eNodeB what size of (initial) grants it should be prepared to give to the UE (UE has little data or not great radio conditions -> small grants(group A), UE has large(r) amount of data and the radio conditions are ok -> bigger grants).(group B)

I hope i am clear here.

Thanks
Sushant
