Methods, systems, and devices for wireless communication are described. A user equipment (UE) may indicate a UE capability for processing a physical downlink shared channel (PDSCH) and exclude an indication that the UE is capable of monitoring for more than one PDSCH transmission within a slot, per component carrier (CC). The UE may receive control information indicating a codebook configuration for hybrid automatic repeat request (HARQ) acknowledgment (ACK) and including a parameter that enables or disables such a capability for the UE to monitor for more than one PDSCH transmission within a slot. The UE may monitor for one or more downlink shared channel transmissions based on the control information and generate a HARQ-ACK codebook for the downlink transmissions, the codebook including feedback for one or more CCs based on the parameter in the control information.
