Downlink control information signaling schemes for bandwidth part switching

An apparatus for wireless communications, comprising:

• a processor;
• and
• memory coupled with the processor, the processor and the memory configured to:
• receive, from a base station and while operating in a first bandwidth part, downlink control information (DCI) during a first transmission time interval;
• receive, as part of the DCI, an indication to switch from operating in the first bandwidth part to operating in a second bandwidth part, the second bandwidth part beginning at a second transmission time interval that is subsequent to the first transmission time interval;
• and
• delay monitoring for a physical downlink control channel (PDCCH) based at least in part on the received DCI triggering the switch from the first bandwidth part to the second bandwidth part.

An apparatus for wireless communications, comprising:

• a processor;
• and
• memory coupled with the processor, the processor and the memory configured to:
• receive first downlink control information (DCI) while operating in a first bandwidth part, the first DCI comprising scheduling information for a first data transmission, wherein the first DCI comprises a null assignment;
• and
• receive, based at least in part on the first DCI comprising the null assignment, scheduling information for a second data transmission, the scheduling information received as part of second DCI that is subsequent to the first DCI.
