Acknowledgment reporting for multi-link transmissions

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

• one or more processors;
• and
• one or more memories coupled with the one or more processors, the one or more processors and one or more memories configured to:
• receive a first signal on a first radio link and a second signal on a second radio link, wherein the first signal and the second signal are associated with a combined downlink signal that is a combination of the first signal and the second signal;
• and
• transmit acknowledgment feedback indicating each of a decoding result of the combined downlink signal, a first individual decoding result of the first signal, and a second individual decoding result of the second signal, wherein the acknowledgment feedback is transmitted in accordance with a phase shift that is determined based at least in part on the first individual decoding result of the first signal and the second individual decoding result of the second signal.

An apparatus for wireless communication at a base station, comprising:

• one or more processors;
• and
• one or more memories coupled with the one or more processors, the one or more processors and one or more memories configured to:
• transmit, to a user equipment (UE), a first signal on a first radio link and a second signal on a second radio link, wherein the first signal and the second signal are associated with a combined downlink signal that is a combination of the first signal and the second signal;
• and
• receive, from the UE, acknowledgment feedback indicating each of a decoding result of the combined downlink signal, a first individual decoding result of the first signal, and a second individual decoding result of the second signal, the acknowledgment feedback comprising a phase shift that indicates the first individual decoding result of the first signal and the second individual decoding result of the second signal.
