Harq-ack transmission method, user equipment and storage medium, and harq-ack reception method and base station

A method of transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK) by a user equipment (UE) in a wireless communication system, the method comprising:

• receiving a time division duplex (TDD) uplink (UL)-downlink (DL) configuration and a semi-persistent scheduling (SPS) configuration;
• performing SPS physical downlink shared channel (PDSCH) reception based on the SPS configuration;
• determining, in a first slot, a first physical uplink control channel (PUCCH) resource for a transmission of HARQ-ACK for the SPS PDSCH reception;
• and
• transmitting the HARQ-ACK for the SPS PDSCH reception,
• wherein determining, in the first slot, the first PUCCH resource for the transmission of the HARQ-ACK for the SPS PDSCH reception comprises:
• determining, in the first slot, the first PUCCH resource to multiplex the HARQ-ACK for the SPS PDSCH reception with another uplink control information (UCI) to be transmitted in the first slot,
• wherein transmitting the HARQ-ACK for the SPS PDSCH reception comprises, based on the first PUCCH resource satisfying conditions in the first slot, transmitting the HARQ-ACK for the SPS PDSCH reception on a second PUCCH resource, and
• wherein the conditions comprise:
• symbols of a corresponding PUCCH resource overlapping with a symbol indicated as DL by the TDD UL-DL configuration.

A user equipment (UE) for transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK) in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• receiving a time division duplex (TDD) uplink (UL)-downlink (DL) configuration and a semi-persistent scheduling (SPS) configuration;
• performing SPS physical downlink shared channel (PDSCH) reception based on the SPS configuration;
• determining, in a first slot, a first physical uplink control channel (PUCCH) resource for a transmission of HARQ-ACK for the SPS PDSCH reception;
• and
• transmitting the HARQ-ACK for the SPS PDSCH reception,
• wherein determining, in the first slot, the first PUCCH resource for the transmission of the HARQ-ACK for the SPS PDSCH reception comprises:
• determining, in the first slot, the first PUCCH resource to multiplex the HARQ-ACK for the SPS PDSCH reception with another uplink control information (UCI) to be transmitted in the first slot,
• wherein transmitting the HARQ-ACK for the SPS PDSCH reception comprises, based on the first PUCCH resource satisfying conditions in the first slot, transmitting the HARQ-ACK for the SPS PDSCH reception on a second PUCCH resource, and
• wherein the conditions comprise:
• symbols of a corresponding PUCCH resource overlapping with a symbol indicated as DL by the TDD UL-DL configuration.

A method of receiving hybrid automatic repeat request-acknowledgement (HARQ-ACK) by a base station (BS) from a user equipment (UE) in a wireless communication system, the method comprising:

• performing SPS physical downlink shared channel (PDSCH) transmission based on the SPS configuration;
• determining, in a first slot, a first physical uplink control channel (PUCCH) resource for a reception of HARQ-ACK for the SPS PDSCH reception;
• and
• receiving the HARQ-ACK for the SPS PDSCH transmission,
• wherein determining, in the first slot, the first PUCCH resource for the reception of the HARQ-ACK for the SPS PDSCH reception comprises:
• determining, in the first slot, the first PUCCH resource to multiplex the HARQ-ACK for the SPS PDSCH reception with another uplink control information (UCI) to be received in the first slot,
• wherein receiving the HARQ-ACK for the SPS PDSCH transmission comprises, based on the first PUCCH resource satisfying conditions in the first slot, receiving the HARQ-ACK for the SPS PDSCH transmission on a second PUCCH resource, and
• wherein the conditions comprise:
• symbols of a corresponding PUCCH resource overlapping with a symbol indicated as DL by the TDD UL-DL configuration.
