Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive an indication of a physical uplink control channel (PUCCH) resource for providing hybrid automatic repeat request (HARQ) feedback for a sidelink data transmission from a second UE. The first UE may transmit the HARQ feedback for the sidelink data transmission on the PUCCH resource. Numerous other aspects are provided.

A method of wireless communication performed by a receiver (Rx) user equipment (UE), comprising:
- receiving a sidelink control information (SCI) communication that includes an indication of a physical uplink control channel (PUCCH) resource for providing hybrid automatic repeat request (HARQ) feedback for a sidelink data transmission from a transmitter (Tx) UE,
- wherein the SCI communication is received from the Tx UE based at least in part on a downlink control information (DCI) format 3_0 communication, received by the Tx UE, including the indication of the PUCCH resource;
- receiving the sidelink data transmission from the Tx UE;
- and
- transmitting, on the PUCCH resource, the HARQ feedback for the sidelink data transmission.
A method of wireless communication performed by a network entity, comprising:
- transmitting, to a transmitter (Tx) user equipment (UE), a downlink control information (DCI) format 3_0 communication that includes an indication of a physical uplink control channel (PUCCH) resource for a receiver (Rx) UE to provide hybrid automatic repeat request (HARQ) feedback for a sidelink data transmission,
- wherein the sidelink data transmission is from the Tx UE and to the Rx UE;
- and
- receiving, from the Rx UE and on the PUCCH resource based at least in part on a sidelink control information (SCI) communication being associated with the DCI format 3_0 communication, the HARQ feedback for the sidelink data transmission,
- wherein the SCI communication includes the indication of the PUCCH resource.
A receiver (Rx) user equipment (UE), comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- receive a sidelink control information (SCI) communication that includes an indication of a physical uplink control channel (PUCCH) resource for providing hybrid automatic repeat request (HARQ) feedback for a sidelink data transmission from a transmitter (Tx) UE,
- wherein the reception of the SCI communication from the Tx UE is based at least in part on a downlink control information (DCI) format 3_0 communication, received by the Tx UE, including the indication of the PUCCH resource;
- receive the sidelink data transmission from the Tx UE;
- and
- transmit, on the PUCCH resource, the HARQ feedback for the sidelink data transmission.
A network entity, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- transmit, to a transmitter (Tx) user equipment (UE), a downlink control information (DCI) format 3_0 communication that includes an indication of a physical uplink control channel (PUCCH) resource for a receiver (Rx) UE to provide hybrid automatic repeat request (HARQ) feedback for a sidelink data transmission,
- wherein the sidelink data transmission is from the Tx UE and to the Rx UE;
- and
- receive, from the Rx UE and on the PUCCH resource based at least in part on a sidelink control information (SCI) communication being associated with the DCI format 3_0 communication, the HARQ feedback for the sidelink data transmission,
- wherein the SCI communication includes the indication of the PUCCH resource.
