Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive an indication from a base station that a downlink shared channel resource in a scheduled occasion, such as a semi-persistently scheduled occasion, includes downlink control information (DCI). The UE may monitor the downlink shared channel resource for the DCI based on the indication. The UE may determine a set of uplink control channel resources based on one or more parameters of the DCI and the downlink shared channel resource. The parameters of the DCI on the semi-persistently scheduled downlink shared channel may implicitly indicate the set of uplink control channel resources to the UE. The UE may transmit an uplink control message to the base station using the set of uplink control channel resources.
