  • Publication number: 20250150213
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration information indicating a sidelink resource pool, a time gap, and a periodicity of feedback occasions. The UE may generate feedback bits associated with multiple received sidelink messages based on the configuration information. The UE may transmit the feedback bits in a single, multi-bit feedback message according to one or more rules. In some examples, the UE may drop one or more sets of feedback bits (e.g., in the case of a collision of too many feedback messages in a single slot) based on a weighted average priority level of one or more valid feedback bits in each of multiple sets of feedback bits.
