Abstract
Methods, systems, and devices for wireless communications are described that provide for transmission of an indication of an activated bandwidth part (BWP) or component carrier (CC), or combination thereof, to a user equipment (UE) through downlink control information (DCI) that is excluding a grant of resources of the BWP or CC. A UE may establish a connection with a base station in which one or more CCs may be configured with one or more BWPs. The base station may indicate which BWP is active for a transmission in DCI that is transmitted subsequent to the configuration of the one or more CCs, and a UE may activate a corresponding BWP or CC based on the indication. In some cases, a CC may be deactivated unless the DCI indicates that at least one BWP of the CC is active.
