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.

說明書

A network may switch an LTE-NR multiplexing scheme between FDM and TDM, based on power headroom reporting (PHR) or UE triggering. When the switching is applied, whether TDM-based multiplexing is applied only to PUCCH/PRACH transmission or to all UL transmissions may also become obvious.

3. DC at the Same Frequency

(1) Control Channel Reception

A UE may expect one or more control channels in one slot. However, processing power of the UE may be limited. Each control channel may perform the same slot scheduling or cross-slot scheduling. Even if the UE expects to receive a single control channel, the UE may receive a plurality of control channels. In this case, one control channel may perform one identical slot scheduling, and another control channel may perform one cross-slot scheduling. That is, the UE may expect to receive one or more control channels, and instead, each control channel may schedule up to one data channel in each slot.
