In LTE/5G everything works based on the IP. Incase of MT call , sender is not aware of destination UE IP then How does he make an request packet and how it reaches the destination, can anyone explain?
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?
