E-UTRA (Evolved Universal Terrestrial Radio Access) - NR Dual Connectivity (EN-DC) of LTE x Down Link (DL) / 1 Up Link (UL) (x=1, 2, 3, 4) and Inter-band NR 2 Down Link (DL) / 1 Up Link (UL)
The present document is a technical report for Dual connectivity (DC) band combinations of LTE xDL/1UL (x=1,2,3,4) + inter-band NR 2DL/1UL under Rel-15 time frame. The purpose is to gather the relevant background information and studies in order to address Dual connectivity (DC) band combinations of LTE xDL/1UL (x=1,2,3,4) + inter-band NR 2DL/1UL in Rel-15 as shown in Table 1-1.
