What changes does SDAP bring from Normal LTE flow? Is SDAP a part of L2 layer?

Question

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 ?

Answer 1

Hi,

SDAP doesn't bring any changes to normal LTE flow, it receives packet form GTP and gives to PDCP, i don't think so SDAP will have headers . it is thin middle layer between PDCP and GTP for QOS handling.

It will be good if you are more specific regarding what do you mean by QOS handling? Is it multiple QOS in a single bearer. You mean to tell that?

Yes, ENB should handle the multiple QOS flow into single bearer.
