Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a grant scheduling a downlink transmission of a set of configurable downlink transmissions. The downlink transmission may include reference slots corresponding to offset values associated with one or more feedback occasions. The UE may construct a feedback codebook based on a first quantity of slots in the set of configurable downlink transmissions, a second quantity of reference slots in the set of configurable downlink transmissions, and a third quantity of configurable offset values associated with one or more feedback occasions. Based on a size of the feedback codebook, the UE may generate feedback bits for reporting whether the UE successfully received a downlink transmission in corresponding slots. In some examples, the UE may identify a slot with a symbol reserved for an uplink transmission, and skip generating a corresponding feedback bit for the identified slot.
