## Abstract

Methods and apparatuses for multiplexing control information in a physical uplink data channel. A method of the UE includes receiving a configuration for a number of hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits per data transport block (TB); receiving a downlink control information (DCI) format scheduling a reception of a data TB; and receiving the data TB that includes a number of data code blocks (CBs). The method further includes determining a number of HARQ-ACK information bits for a respective number of CB groups (CBGs); determining CBs per CBG; generating HARQ-ACK information bits; and generating a HARQ-ACK codeword. Additionally, the method includes transmitting the HARQ-ACK codeword in a physical uplink control channel (PUCCH) or in a physical uplink shared data channel (PUSCH).
