Multiplexing control information in a physical uplink data channel

A base station, comprising:

• a transmitter configured to:
• transmit a configuration for a number of NHARQ-ACKTB hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits per data transport block (TB),
• transmit a downlink control information (DCI) format scheduling a transmission of a data TB, and
• transmit the data TB that includes a number of NCBTB data code blocks (CBs);
• and
• a processor configured to:
• determine a number of NHARQ-ACKTB HARQ-ACK information bits for a respective number of CB groups (CBGs),
• determine NCBCBG=┌NCBTB/NHARQ-ACKTB┐ CBs per CBG for first mod(NCBTB, NHARQ-ACKTB) CBGs, and NCBCBG=└NCBTB/NHARQ-ACKTB┘ CBs per CBG for last NHARQ-ACKTB−mod(NCBTB, NHARQ-ACKTB) CBGs,
• determine mod(NCBTB, NHARQ-ACKTB) HARQ-ACK information bits for the first mod(NCBTB, NHARQ-ACKTB) CBGs,
• determine NHARQ-ACKTB−mod(NCBTB, NHARQ-ACKTB) HARQ-ACK information bits for the last NHARQ-ACKTB−mod(NCBTB, NHARQ-ACKTB) CBGs, and
• determine a HARQ-ACK codeword that includes the mod(NCBTB, NHARQ-ACKTB) HARQ-ACK information bits followed by the NHARQ-ACKTB−mod(NCBTB, NHARQ-ACKTB) HARQ-ACK information bits, wherein ┌ ┐ is a ceiling function, └ ┐ is a floor function, and mod is a modulo function;
• and
• a receiver configured to receive the HARQ-ACK codeword in a physical uplink control channel (PUCCH) or in a physical uplink shared data channel (PUSCH).
