However All the protocol is reestablishing but what is the use of keeping AM state variables same
Just thinking a logical way, If we don't do, it will reset the whole RLC during re-establishment
In LTE RLC does the HARQ re-ordering , but in 5G RLC doesn't have any functionality wrt HARQ er-ordering then which layer is responsible for this?
During re-establishment/HO transmitter RLC (NR) will give the information about last succesfull sent SN to PDCP . But in LTE - NR case how does LTE PDCP understands RLC NR status. Do we need to modify the LTE PDCP functionality to interoperable with NR?
