E-UTRA (Evolved Universal Terrestrial Radio Access) - NR Dual Connectivity (EN-DC) of LTE 3 Down Link (DL) / 1 Up Link (UL) and 1 NR band
The present document is a technical report for Dual connectivity (DC) band combinations of LTE 3DL/1UL + one NR band 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 3DL/1UL + one NR band for the Rel-15 band combinations in Table 1-1.
