Hybrid Automatic Repeat Request Feedback Control by Base Station

Abstract

A method may include transmitting, to a wireless device, radio resource control (RRC) messages that include parameters of a multicast and broadcast service (MBS). The parameters may indicate a first feedback operation with hybrid automatic repeat request (HARQ) feedback being enabled and may indicate a second feedback operation with the HARQ feedback being disabled. A group common downlink control information (DCI) may indicate one of the first feedback operation or the second feedback operation. The method may also include transmitting a first group common DCI, which may schedule a first transport block (TB) of the MBS and may indicate the first feedback operation. The method may further include receiving, based on the first group common DCI indicating the first feedback operation, a first HARQ feedback for the first TB.
