WebOption 1 has the advantages of short data interruption time and good service continuity during handover while the disadvantage is that the source base station needs to forward data to multiple candidate base stations resulting in large network overhead. Option 2, on the contrary, has the advantage of forwarding data to only one target base station. WebInterworking with LTE - NSA / ENDC in Detail . This is about one of NR deployment options where LTE work as a master and NR work as a secondary cell (In 3GPP terms, this is about EN-DC (EUTRA-NR Dual Connectivity) / MR-DC with EPC as described in 37.340).
