Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive sidelink control information (SCI) indicating that the UE is to transmit sidelink hybrid automatic repeat request (HARQ) feedback in a type 3 codebook. The UE may transmit the type 3 codebook on a physical sidelink channel for one or more sidelink HARQ processes based at least in part on the SCI. Numerous other aspects are provided.

A method of wireless communication performed by a user equipment (UE), comprising:
- receiving, from a second UE, sidelink control information (SCI) indicating that the UE is to use a type 3 codebook for transmitting sidelink hybrid automatic repeat request (HARQ) feedback;
- and
- transmitting, to the second UE, the type 3 codebook on a physical sidelink channel for one or more sidelink HARQ processes based at least in part on the SCI indicating that the UE is to use the type 3 codebook for transmitting the sidelink HARQ feedback.
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting, to a second UE, sidelink control information (SCI) indicating that the second UE is to use a type 3 codebook for transmitting sidelink hybrid automatic repeat request (HARQ) feedback for one or more sidelink HARQ processes;
- and
- receiving the type 3 codebook from the second UE on a physical sidelink channel after transmitting the SCI and based at least in on the SCI indicating that the second UE is to use the type 3 codebook for transmitting the sidelink HARQ feedback.
A user equipment (UE) for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- receive, from a second UE, sidelink control information (SCI) indicating that the UE is to use a type 3 codebook for transmitting sidelink hybrid automatic repeat request (HARQ) feedback;
- and
- transmit the type 3 codebook on a physical sidelink channel for one or more sidelink HARQ processes based at least in part on the SCI indicating that the UE is to transmit use the type 3 codebook for transmitting the sidelink HARQ feedback.
