Signaling for transmission of uplink control information in a component carrier group

A network entity supporting a first cell group and a second cell group, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the network entity to:
• output one or more first control messages scheduling a downlink transmission in the first cell group comprising a first cell, the one or more first control messages indicating that a first uplink control information (UCI) carrying feedback associated with the downlink transmission in the first cell group is to be transmitted to the first cell in the first cell group and that a second UCI carrying the feedback associated with the downlink transmission in the first cell group is to be transmitted to a second cell of the second cell group;
• obtain, via the first cell of the first cell group in accordance with the one or more first control messages, the first UCI carrying the feedback associated with the downlink transmission in the first cell group;
• and
• obtain, via the second cell of the second cell group and a resource of the second cell that is based at least in part on the one or more first control messages, the second UCI carrying the feedback associated with the downlink transmission in the first cell group.

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

• receiving one or more first control messages scheduling a downlink transmission in a first cell group comprising a first cell, the one or more first control messages indicating that a first uplink control information (UCI) carrying feedback associated with the downlink transmission in the first cell group is to be transmitted to the first cell in the first cell group and that a second UCI carrying the feedback associated with the downlink transmission in the first cell group is to be transmitted to a second cell of a second cell group;
• transmitting, to the first cell of the first cell group in accordance with receiving the one or more first control messages, the first UCI carrying the feedback associated with the downlink transmission in the first cell group;
• and
• transmitting, to the second cell of the second cell group and using a resource of the second cell that is based at least in part on the one or more first control messages, the second UCI carrying the feedback associated with the downlink transmission in the first cell group.

A method for wireless communications by a network entity supporting a first cell group and a second cell group, comprising:

• outputting one or more first control messages scheduling a downlink transmission in the first cell group comprising a first cell, the one or more first control messages indicating that a first uplink control information (UCI) carrying feedback associated with the downlink transmission in the first cell group is to be transmitted to the first cell in the first cell group and that a second UCI carrying the feedback associated with the downlink transmission in the first cell group is to be transmitted to a second cell of the second cell group;
• obtaining, via the first cell of the first cell group in accordance with the one or more first control messages, the first UCI carrying the feedback associated with the downlink transmission in the first cell group;
• and
• obtaining, via the second cell of the second cell group and a resource of the second cell that is based at least in part on the one or more first control messages, the second UCI carrying the feedback associated with the downlink transmission in the first cell group.
