1. A method for wireless communication at a user equipment (UE), comprising:
receiving a feedback resource configuration indicating multiple feedback resource sets for a plurality of sub-slots within a slot, the multiple feedback resource sets for reporting of feedback by the UE within the slot, wherein each feedback resource set of the multiple feedback resource sets is completely within a respective sub-slot of the slot based at least in part on the feedback resource configuration, wherein the multiple feedback resource sets are configured in accordance with a requirement to ensure that none of the multiple feedback resource sets overlap, and wherein an overlap of two or more feedback resource sets within the multiple feedback resource sets is associated with an error condition;
receiving an indication of a first feedback timing parameter indicating a first sub-slot that includes a first feedback resource set of the multiple feedback resource sets via which the UE is to provide feedback for a first data transmission, wherein the first feedback timing parameter indicates that the first sub-slot occurs a first quantity of sub-slots after a last sub-slot of the first data transmission, the last sub-slot of the first data transmission being a sub-slot that includes a last symbol of the first data transmission;
receiving an indication of a second feedback timing parameter indicating a second sub-slot that includes a second feedback resource set of the multiple feedback resource sets via which the UE is to provide feedback for a second data transmission, wherein the second feedback timing parameter indicates that the second sub-slot occurs a second quantity of sub-slots after a last sub-slot of the second data transmission, the last sub-slot of the second data transmission being a sub-slot that includes a last symbol of the second data transmission;
receiving the first data transmission via a first data channel and the second data transmission via a second data channel;
transmitting, using the first feedback resource set within the first sub-slot of the slot, the feedback for the first data transmission, the feedback for the first data transmission transmitted the first quantity of sub-slots after the last sub-slot of the first data transmission in accordance with the first feedback timing parameter; and
transmitting, using the second feedback resource set within the second sub-slot of the slot, the feedback for the second data transmission, the feedback for the second data transmission transmitted the second quantity of sub-slots after the last sub-slot of the second data transmission in accordance with the second feedback timing parameter.
