Hi,
Yes there are lot of changes to QOS in 5G. there is a new layer called SDAP which handles QOS in 5G .In LTE single bearer can handle one QOS flow but incase of 5G single bearer is handling multiple QOS flow.Full SDAP functionality is not defined yet.Maybe this year june we will receive all information about QOS flow and QOS identifier.
Is there any changes in architecture of 5G compare to LTE ?Do all LTE entity exist in 5G?
Network slicing is a concept by using that virtual networks are created for different sets of devices. In case of next generation radio (NR), is there any change at L1/L2 to support network slicing compare to the LTE implementation ?
