Abstract
Embodiments include methods, performed by a user equipment (UE), for hybrid ARQ (HARQ) feedback in relation to multicast transmissions from a network node in a radio access network (RAN). Such methods include receiving, from the network node, first downlink control information (DCI) scheduling a first multicast transmission associated with the UE and determining a HARQ feedback mode for the first multicast transmission. Such methods also include, based on the first DCI, attempting to decode the first multicast transmission; and selectively transmitting HARQ feedback related to the first multicast transmission to the network node based on the determined HARQ feedback mode and on whether the attempt to decode is successful or unsuccessful. Embodiments also include complementary methods for a network node, as well as UEs and network nodes configured to perform such methods.
