## Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive multiple semi-persistent scheduling (SPS) configurations, the multiple SPS configurations including a first SPS configuration associated with a first control resource set (CORESET) group and a second SPS configuration associated with a second CORESET group. The UE may receive a downlink control information (DCI) message indicating to release one or more SPS configurations of the multiple SPS configurations. The UE may release the one or more SPS configurations in accordance with the DCI message. The UE may transmit hybrid automatic repeat request (HARQ) feedback regarding the DCI message on a selected HARQ feedback resource. Numerous other aspects are described.
