Feedback techniques for group-common PDCCH transmissions

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

• monitoring for a first group downlink control information transmission associated with a UE group;
• receiving a second group downlink control information transmission referencing the first group downlink control information transmission;
• determining a feedback condition for the first group downlink control information transmission based at least in part on the second group downlink control information transmission;
• and
• transmitting feedback information for the first group downlink control information transmission based at least in part on the monitoring and the determined feedback condition.

An apparatus for wireless communication 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 a first group downlink control information transmission associated with a UE group, the first group downlink control information transmission referencing a second group downlink control information transmission;
• determine a feedback condition for the second group downlink control information transmission based at least in part on the first group downlink control information transmission;
• monitor for the second group downlink control information transmission based at least in part on the first group downlink control information transmission;
• and
• transmit feedback information for the second group downlink control information transmission based at least in part on the monitoring and the determined feedback condition.
