Feedback transmissions using uplink shared channel

A method for wireless communications at a base station, comprising:

• transmitting an uplink grant that indicates scheduling information for an uplink shared channel transmission for a user equipment (UE);
• transmitting, after transmitting the uplink grant, a downlink grant that indicates scheduling information for a downlink shared channel transmission for the UE or a release of periodically scheduled resources for the UE;
• and
• monitoring for the uplink shared channel transmission from the UE based at least in part on the scheduling information for the uplink shared channel transmission indicated by the uplink grant, the uplink shared channel transmission comprising feedback information associated with the downlink grant.

An apparatus for wireless communications at a user equipment (UE), 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:
• receive an uplink grant that indicates scheduling information for an uplink shared channel transmission for the UE;
• receive, after receiving the uplink grant, a downlink grant that indicates scheduling information for a downlink shared channel transmission for the UE;
• monitor for the downlink shared channel transmission based at least in part on the scheduling information for the downlink shared channel transmission;
• generate feedback information for the downlink shared channel transmission based at least in part on the monitoring and receiving the downlink grant after receiving the uplink grant;
• and
• perform the uplink shared channel transmission including the feedback information associated with the downlink shared channel transmission based at least in part on the scheduling information for the uplink shared channel transmission indicated by the uplink grant.
