Simultaneous feedback information and uplink shared channel transmissions

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

• transmitting to a user equipment (UE) a piggybacking status for a first uplink carrier of a plurality of uplink carriers configured for the UE;
• transmitting a first uplink grant that indicates an uplink shared channel occasion on the first uplink carrier, wherein the uplink shared channel occasion overlaps in time with an uplink control channel occasion associated with uplink control information for a downlink transmission from the base station;
• and
• receiving, based at least in part on the piggybacking status for the first uplink carrier, an uplink shared channel transmission on the first uplink carrier during the uplink shared channel occasion and an uplink control transmission of the uplink control information on a second uplink carrier of the plurality of uplink carriers during the uplink control channel occasion.

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 piggybacking status for a first uplink carrier of a plurality of uplink carriers configured for the UE;
• receive a first uplink grant that indicates an uplink shared channel occasion on the first uplink carrier;
• generate uplink control information for a downlink transmission from a base station, wherein the uplink control information is associated with an uplink control channel occasion that overlaps in time with the uplink shared channel occasion;
• and
• perform, based at least in part on the piggybacking status for the first uplink carrier, an uplink shared channel transmission on the first uplink carrier during the uplink shared channel occasion and an uplink control transmission of the uplink control information on a second uplink carrier of the plurality of uplink carriers during the uplink control channel occasion.
