Rel-19 Dual Connectivity of EN-DC and NE-DC configurations consisting of 2 bands LTE inter-band CA (2DL/1UL) and 1 band NR (1DL/1UL), or consisting of 1 band LTE (1DL/1UL) and 2 bands NR inter-band CA (2DL/1UL)
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 present document is a technical report for Rel-19 Dual Connectivity of EN-DC and NE-DC configurations consisting of 2 bands LTE inter-band CA (2DL/1UL) and 1 NR band (1DL/1UL), or consisting of 1 band LTE (1DL/1UL) and 2 bands NR inter-band CA (2DL/1UL) under Rel-19 time frame. The purpose is to gather the relevant background information and studies to address DC band combinations consisting of 2 bands LTE inter-band CA (2DL/1UL) and 1 NR band (1DL/1UL), or consisting of 1 band LTE (1DL/1UL) and 2 bands NR inter-band CA (2DL/1UL) in Rel-19 as shown in Table 1-1.
