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.

2) The UL resource is dynamically split between CGs, and the payload is not mixed in each CG.

3) The UL resource is dynamically split between CGs, and the payload may be mixed in each CG.

(1) Initial Access Procedure (i.e., Random Access (RACH)-Related Procedure)

First, an initial access procedure in a dual connectivity will be described according to an embodiment of the present disclosure. When a UE is connected to only one CG, it is not necessary to consider any time division multiplexing (TDM)-based multiplexing between UL transmissions to each CG. However, if an additional CG is configured by the dual connectivity, the initial access procedure may be considered as follows.
