The present document is a technical report for Dual Connectivity (EN-DC) of 3 LTE bands (3DL/1UL) and 1 NR band (1DL/1UL) under Rel-16 time frame. The purpose is to gather the relevant background information and studies in order to address Dual Connectivity (EN-DC) of 3 LTE band (3DL/1UL) and 1 NR band (1DL/1UL)for the Rel-16 band combinations in Table 1-1
. The co-existence analysis and 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.
This TR contains a general part and band specific combination part. The actual requirements are added to the corresponding technical specifications.
