Rel-19 Dual Connectivity of EN-DC and NE-DC configurations consisting of 2 different bands downlink (DL) with 2 different bands uplink (UL) (1 LTE band and 1 NR band)
The present document is a technical report for Dual Connectivity of EN-DC and NE-DC configurations consisting of 2 different bands downlink (DL) with 2 different bands uplink (UL) (1 LTE band and 1 NR band) under Rel-19 time frame.
The purpose is to gather the relevant background information and studies in order to address Dual Connectivity (DC) of 1 LTE band (1DL/1UL) and 1 NR band (1DL/1UL) for the Rel-19 band combinations in Table 1-1, 1-2, 1-3 and 1-4, including EN-DC and NE-DC combinations. The actual requirements are added to the corresponding technical specifications.
