Abstract
Provided are a method for transmitting an ACK/NACK in a wireless communication system and a device using the same. The device receives DL control information having a downlink (DL) grant and an ACK/NACK resource indicator (ARI), and receives a DL transmission block based on the basis of the DL grant. On the basis of the ARI, the device selects a physical uplink control channel (PUCCH) format, and decides on a PUCCH resource for the selected PUCCH format. The device transmits the ACK/NACK of the DL transmission block by using the selected PUCCH format.
Claims12
A method for transmitting an ACK/NACK in a wireless communication system, the method comprising:
- receiving, by a wireless device, downlink (DL) control information including a DL grant and an ACK/NACK resource indicator (ARI);
- receiving, by the wireless device, a DL transport block based on the DL grant;
- selecting, by the wireless device, a physical uplink control channel (PUCCH) format based on the ARI;
- determining, by the wireless device, a PUCCH resource for the selected PUCCH format based on the ARI;
- and
- transmitting, by the wireless device, an ACK/NACK for the DL transport block by using the selected PUCCH format.
An apparatus for transmitting an ACK/NACK in a wireless communication system, the apparatus comprising:
- a transceiver configured to transmit and receive a radio signal;
- and
- a processor operatively coupled to the transceiver and configured to:
- control the transceiver to receive downlink (DL) control information including a DL grant and an ACK/NACK resource indicator (ARI);
- control the transceiver to receive a DL transport block based on the DL grant;
- select a physical uplink control channel (PUCCH) format based on the ARI;
- determine a PUCCH resource for the selected PUCCH format based on the ARI;
- and
- control the transceiver to transmit an ACK/NACK for the DL transport block by using the selected PUCCH format.
