Feedback schemes for multiple component carrier scheduling and joint feedback reporting

A method for wireless communications at a user equipment (UE), comprising:

• receiving, from a base station during a physical downlink control channel monitoring occasion, one or more first downlink control information scheduling the UE for a corresponding one or more first physical downlink shared channel resources on a first component carrier, the one or more first downlink control information associated with a first control resource set pool index;
• receiving, during the physical downlink control channel monitoring occasion, one or more second downlink control information scheduling the UE for a corresponding one or more second physical downlink shared channel resources on the first component carrier, the one or more second downlink control information associated with a second control resource set pool index;
• identifying a plurality of downlink assignment indices for the one or more first downlink control information and the one or more second downlink control information, wherein values of the plurality of downlink assignment indices are based at least in part on the one or more first downlink control information and the one or more second downlink control information both scheduling physical downlink shared channel resources on a same component carrier;
• and
• transmitting feedback based at least in part on the plurality of downlink assignment indices.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a base station during a physical downlink control channel monitoring occasion, first downlink control information scheduling the UE for a first physical downlink shared channel resource on a first component carrier and for a second physical downlink shared channel resource on a second component carrier;
• receive, during the physical downlink control channel monitoring occasion, second downlink control information scheduling the UE for a third physical downlink shared channel resource on the second component carrier;
• identify a plurality of downlink assignment indices for the first downlink control information and the second downlink control information, wherein the first downlink control information has one or more downlink assignment indices whose values are based at least in part on the first downlink control information scheduling physical downlink shared channel resources on different component carriers;
• and
• transmit feedback based at least in part on the plurality of downlink assignment indices.
