摘要

A method and an apparatus for supporting dual connectivity (DC) in new radio access technology (NR) are provided. As an embodiment, a method for performing uplink (UL) transmission by user equipment (UE) is provided. More specifically, the UE receives a semi-persistent configuration with respect to a first UL resource of a first carrier group (CG) and a second UL resource of a second CG that are separated from one another, and performs UL transmission to the first CG using the first UL resource only.
