Method, user equipment, processing device, storage medium, and computer program for receiving downlink channel, and method and base station for transmitting downlink channel

A user equipment (UE) configured to transmit control information in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• determining, in a first slot, a first physical uplink control channel (PUCCH) for a transmission of first hybrid automatic repeat request-acknowledgement (HARQ-ACK) information bits for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) receptions;
• based on the first PUCCH overlapping with a symbol indicated as downlink, determining a second slot and a second PUCCH in the second slot to multiplex HARQ-ACK information bits that includes second HARQ-ACK information bits from the first HARQ-ACK information bits;
• and
• transmitting the second PUCCH in the second slot,
• wherein, based on the UE receiving a PDSCH providing a transport block (TB) for a same HARQ process as a HARQ-ACK information bit from the second HARQ-ACK information bits prior to transmitting the second PUCCH, the UE does not include the HARQ-ACK information bit in the HARQ-ACK information bits.

A base station (BS) configured to receive control information from a user equipment (UE) in a wireless communication system, the BS comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• determining, in a first slot, a first physical uplink control channel (PUCCH) for a reception of first hybrid automatic repeat request-acknowledgement (HARQ-ACK) information bits for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) transmissions;
• based on the first PUCCH overlapping with a symbol indicated as downlink, determining a second slot and a second PUCCH to receive HARQ-ACK information bits that includes second HARQ-ACK information bits from the first HARQ-ACK information bits;
• and
• receiving the second PUCCH in the second slot,
• wherein, based on the BS transmitting, to the UE, a PDSCH providing a transport block (TB) for a same HARQ process as a HARQ-ACK information bit from the second HARQ-ACK information bits prior to receiving the second PUCCH, the HARQ-ACK information bits do not include the HARQ-ACK information bit.
