wherein the one or more RNTIs includes a first RNTI pertaining to a first groupcast service or broadcast service of the at least one groupcast service or broadcast service;
receive a first Hybrid Automatic Repeat Request (HARQ) configuration indicating whether a HARQ is enabled or disabled for the first RNTI;
receive a first set of transmissions, the first set of transmissions being part of the first groupcast service or broadcast service;
determine whether the HARQ is enabled or disabled for the first groupcast service or broadcast service based on the first HARQ configuration;
based on the HARQ being enabled for the groupcast service or broadcast service, transmit a HARQ feedback for the first set of transmissions; and
