Semi-static HARQ-ACK codebook construction for frequency-multiplexed downlink data transmission

An apparatus, comprising:

• at least one processor;
• and
• at least one memory including program code, the at least one memory and the program code being configured to, with the at least one processor, cause the apparatus at least to:
• receive downlink configuration information from a network device,
• receive at least two frequency-multiplexed downlink data transmissions at one downlink data transmission occasion, the at least two frequency-multiplexed downlink data transmissions including one or more multicast or broadcast downlink transmissions, and
• set, based on the downlink configuration information and an error state of the at least two frequency-multiplexed downlink data transmissions, a single acknowledgement indication in a semi-static hybrid automatic repeat request acknowledgement codebook to be transmitted to the network device for the one downlink data transmission occasion;
• wherein the downlink configuration information indicates how to set the single acknowledgement indication in the semi-static hybrid automatic repeat request acknowledgement codebook.
