Bandwidth part activation, deactivation, and switching in wireless communications

A method for wireless communication, comprising:

• establishing, at a base station, a connection with a user equipment (UE) using a primary component carrier (CC), the primary CC having a plurality of bandwidth parts (BWPs) each having a portion of a frequency bandwidth of the primary CC;
• formatting first downlink control information (DCI) to include an indication to the UE to activate a selected BWP of the plurality of BWPs, the first DCI excluding a grant of resources of the selected BWP for the UE;
• and
• transmitting the first DCI to the UE.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• establish, at a user equipment (UE), a connection with a base station using a primary component carrier (CC), the primary CC having a plurality of bandwidth parts (BWPs) each having a portion of a frequency bandwidth of the primary CC;
• receive first downlink control information (DCI), the first DCI including an indication to activate a selected BWP of the plurality of BWPs, the first DCI excluding a grant of resources of the selected BWP for the UE;
• and
• activate the selected BWP based at least in part on the first DCI.
