    Abstract: Certain aspects of the present disclosure provide techniques for techniques for providing sidelink feedback. Certain aspects provide a method for wireless communication by a first user equipment (UE). The method generally includes receiving, from a second UE, one or more sidelink data messages and transmitting, to the second UE, via a first sidelink feedback channel resource, a first feedback message comprising one or more feedback bits associated with the one or more sidelink data messages, wherein: the first sidelink feedback channel resource comprises a first partial interlace group of a first interlace group of resource blocks, and the first partial interlace group comprises at least two first resource blocks.

    Abstract: The apparatus may be a UE configured to select, from a plurality of PSFCH resource sub-pools of a PSFCH resource pool for receiving HARQ feedback, a particular PSFCH resource sub-pool for receiving HARQ feedback associated with a particular SL transmission; transmit, to at least one UE, a PSRI identifying the particular PSFCH resource sub-pool; and receive, from the at least one UE, HARQ feedback regarding the particular SL transmission, the HARQ feedback being received via resources in the PSFCH resource sub-pool indicated by the PSRI. The apparatus may be a base station in a Mode 1 resource allocation that may select, from a plurality of PSFCH resource sub-pools of a PSFCH resource pool for receiving HARQ feedback, a particular PSFCH resource sub-pool for receiving HARQ feedback associated with the particular SL transmission and transmit, to a UE, a PSRI identifying the particular PSFCH resource sub-pool.

    Abstract: This disclosure provides systems, methods and apparatuses for indicating sidelink processes for sidelink feedback. A second user equipment (UE) may request hybrid automatic repeat request (HARQ) responses from a first UE for a particular set of sidelink processes over a physical sidelink feedback channel. To indicate multiple sidelink processes, the second UE may indicate, in sidelink control information, a window of sidelink processes. The window may be a sliding window that starts with a starting sidelink process and extends through other sidelink processes. The second UE may transmit data for the sidelink processes in the sliding window and receive feedback for the indicated sidelink processes. In some aspects, the first UE may select, in coordination with the second UE, the sidelink processes for which feedback is to be provided.

    Abstract: Techniques and apparatus for a resource pool configuration for multiple bits physical sidelink feedback channel (PSFCH) are described. An example technique includes receiving a plurality of transmissions from a user equipment (UE) on a plurality of sidelink subchannels. At least one resource set for transmitting feedback corresponding to the plurality of transmissions is determined, based on at least one of the plurality of transmissions. Feedback corresponding to the plurality of transmissions is transmitted using the at least one resource set. Another example technique includes sending a plurality of transmissions to a UE on a plurality of sidelink subchannels and monitoring for feedback corresponding to the plurality of transmissions, based on a codebook size associated with the feedback.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.
