Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a capability of receiving multiple downlink control information (DCI) signals or messages from one or more base stations indicating corresponding downlink data channels for a same transport block (TB) (e.g., for a same feedback process, where each downlink data channel has a same feedback identification). Subsequently, the UE may receive one or more DCIs, each scheduling a respective downlink data channel for the same TB, where the UE is then expected to transmit acknowledgement (ACK) feedback for the TB. Accordingly, the UE may transmit the ACK feedback (e.g., in a joint feedback message or via separate feedback messages) for the corresponding downlink data channels based on attempting to decode the TB on resources of the downlink data channels as indicated by the multiple DCIs.
