Abstract
(EN) A wireless device receives parameters, of multicast transmissions, including: a first hybrid automatic repeat request (HARQ) feedback indication associated with a semi-persistent scheduling (SPS) configuration; and a second HARQ feedback indication associated with a dynamic scheduling. An indication of an activation of the SPS configuration is received. Based on the SPS configuration being activated, the first HARQ feedback indication is selected from the first HARQ feedback indication and the second HARQ feedback indication. Based on the first HARQ feedback indication indicating that a HARQ feedback is enabled, HARQ feedbacks for one or more transport blocks associated with the SPS configuration are transmitted.
