1. An apparatus for wireless communication at a user equipment (UE), comprising:
at least one processor; and
memory coupled with the at least one processor, the memory storing instructions executable by the at least one processor to cause the UE to:
receive an indication of one or more conflict conditions for identification of conflicts between uplink feedback messages and a communication frame structure;
receive a downlink message within a set of semi-persistent downlink resources, the downlink message associated with a first uplink resource for transmitting a feedback message associated with the downlink message, the first uplink resource being included within a subband full-duplex slot of the communication frame structure that includes one or more uplink subbands; and
transmit the feedback message associated with the downlink message via the first uplink resource or a second uplink resource that is deferred relative to the first uplink resource based on whether feedback deferral for the downlink message is triggered in accordance with the one or more conflict conditions, wherein the second uplink resource is included within a second slot that is subsequent to the subband full-duplex slot.
