E-UTRA (Evolved Universal Terrestrial Radio Access) - NR Dual Connectivity (EN-DC) of LTE 1 Down Link (DL) / 1 Up Link (UL) and inter- / intra-band NR 2 Down Link (DL) / 2 Up Link (UL) bands (Frequency Range 1 (FR1) + Frequency Range 2 (FR2))
The present document is a technical report for Dual connectivity (DC) band combinations of LTE 1DL/1UL + inter-/intra-band NR 2DL/2UL bands (FR1+FR2) 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 1DL/1UL + inter-/intra-band NR 2DL/2UL bands (FR1+FR2)in Rel-15 as shown in Table 1-1.
