Semi-persistent scheduling of multicast and broadcast services

A base station comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the base station to:
• transmit, to a wireless device, radio resource control messages comprising configuration parameters of a first semi-persistent scheduling (SPS) for multicast and broadcast services (MBS), wherein the configuration parameters of the first SPS comprise a first hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook index;
• transmit a multicast transport block (TB) based on receiving a group common downlink control information (DCI) indicating an activation of the first SPS;
• and
• receive, from the wireless device, first feedback for the multicast TB in a first HARQ-ACK codebook, of HARQ-ACK codebooks, indicated by the first HARQ-ACK codebook index.

A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:

• receive, from a base station, radio resource control messages comprising configuration parameters of a first semi-persistent scheduling (SPS) for multicast and broadcast services (MBS), wherein the configuration parameters of the first SPS comprise a first hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook index;
• receiving a multicast transport block (TB) based on receiving a group common downlink control information (DCI) indicating an activation of the first SPS;
• and
• transmitting first feedback for the multicast TB in a first HARQ-ACK codebook, of HARQ-ACK codebooks, indicated by the first HARQ-ACK codebook index.
