In LTE and 5G-NR, signalling messages exchange are same except initial differences before UE starts with RACH procedure.
In LTE, cell synchronization happens first and then after UE starts with RACH procedure. When 5G NR would be operating in beam forming mode, UE need to detect and select the best beam before initiating the RACH procedure. This is the only difference that I know.
