1. A user equipment (UE) device, comprising:
at least one antenna;
at least one radio, configured to perform wireless communication using at least one radio access technology; and
one or more processors coupled to the at least one radio, wherein the at least one radio and the one or more processors are configured to receive Multicast Broadcast Service (MBS) data,
wherein the one or more processors are configured to cause the UE device to:
receive, from a network device, a timing offset indicating a slot offset for a Hybrid Automatic Repeat request (HARQ) feedback transmission, wherein the timing offset is a group specific timing offset which is smaller than a cell specific timing offset, the group including a plurality of UE devices which receive the MBS data and do not locate at a cell edge;
determine a transmission timing for an HARQ feedback transmission for the MBS data based on the timing offset; and
forgo the HARQ feedback transmission for the MBS data when the group specific timing offset is smaller than a UE specific timing offset.
