Dual Connectivity (EN-DC) of LTE inter-band CA xDL/1UL bands (x=2,3,4) and NR FR1 1DL/1UL band and NR FR2 1DL/1UL band
The present document is a technical report for Dual Connectivity (EN-DC) of LTE inter-band CA (xDL/1UL) (x=2,3,4) bands and NR FR1 1DL/1UL band and NR FR2 1DL/1UL band under Rel-16 time frame. The purpose is to gather the relevant background information and studies in order to address EN-DC of LTE inter-band CA (xDL/1UL) (x=2,3,4) bands and NR FR1 1DL/1UL band and NR FR2 1DL/1UL band for the Rel-16 band combinations in Table 1-1. The RF front end requirements such as Delta RIB,C and TIB,C are described based on the band combination basis since such information have no difference between the EN-DC configulations consisting with the same E-UTRA band and the same NR band.
