Abstract
According to certain embodiments, a method by a wireless device for transmitting Hybrid Automatic Repeat Request (HARQ) feedback includes obtaining a Physical Uplink Control Channel (PUCCH) configuration parameter comprising a channel code type. Based on the PUCCH configuration parameter comprising the channel code type, a PUCCH format is selected for transmitting the HARQ feedback to a network node on the PUCCH, and the HARQ feedback is transmitted to the network node.
Claims24
A method by a wireless device for transmitting Hybrid Automatic Repeat Request (HARQ) feedback, comprises:
- obtaining, by the wireless device, a Physical Uplink Control Channel (PUCCH) configuration parameter comprising a channel code type and a PUCCH resource that is explicitly configured with the channel code type, the PUCCH resource comprising a PUCCH timing indication and/or Acknowledgement/Not-Acknowledgement (ACK/NACK) resource indicator (ARI);
- determining a codebook size based on the channel code type;
- based on the PUCCH configuration parameter comprising the channel code type, selecting a PUCCH format for transmitting the HARQ feedback to a network node on the PUCCH;
- and
- transmitting the HARQ feedback to the network node.
A wireless device for providing Hybrid Automatic Repeat Request (HARQ) feedback comprising:
- memory operable to store instructions;
- and
- processing circuitry operable to execute the instructions to cause the wireless device to:
- obtain a Physical Uplink Control Channel (PUCCH) configuration parameter comprising a channel code type and a PUCCH resource that is explicitly configured with the channel code type, the PUCCH resource comprising a PUCCH timing indication and/or Acknowledgement/Not-Acknowledgement (ACK/NACK) resource indicator (ARI);
- determine a codebook size based on the channel code type;
- based on the PUCCH configuration parameter comprising the channel code type, select a PUCCH format for transmitting the HARQ feedback to a network node on the PUCCH;
- and
- transmit the HARQ feedback to the network node.
A method by a network node for receiving Hybrid Automatic Repeat Request (HARQ) feedback, comprises:
- transmitting, to a wireless device, a Physical Uplink Control Channel (PUCCH) configuration parameter comprising a channel code type and a PUCCH resource that is explicitly configured with the channel code type, the PUCCH resource comprising a PUCCH timing indication and/or Acknowledgement/Not-Acknowledgement (ACK/NACK) resource indicator (ARI), wherein a codebook size is based on the channel code type;
- and
- receiving, on the PUCCH and via the PUCCH resource, the HARQ feedback formatted based on at least the channel code type.
A network node for receiving Hybrid Automatic Repeat Request (HARQ) feedback, the network node comprising:
- memory operable to store instructions;
- and
- processing circuitry operable to execute the instructions to cause the network node to:
- transmit, to a wireless device, a Physical Uplink Control Channel (PUCCH) configuration parameter comprising a channel code type and a PUCCH resource that is explicitly configured with the channel code type, the PUCCH resource comprising a PUCCH timing indication and/or Acknowledgement/Not-Acknowledgement (ACK/NACK) resource indicator (ARI), wherein a codebook size is based on the channel code type;
- and
- receive, on the PUCCH and via the PUCCH resource, the HARQ feedback formatted based on at least the channel code type.
