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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may identify a sidelink resource allocation mode that indicates a manner in which one or more sidelink resources are allocated for use by the transmitter UE. The UE may transmit, to a receiver UE, sidelink control information (SCI) that includes an indication that is based at least on part on the sidelink resource allocation mode. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a communication from a second UE. The first UE may select an index that represents multiple control bits associated with the communication. The first UE may transmit an indication of the index in a portion of a physical sidelink feedback channel (PSFCH) resource pool that is selected based at least in part on the index. Numerous other aspects are described.

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.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to transmit feedback information via a configurable quantity of interlaced resource blocks (IRBs) in one or more interlaces of a sidelink feedback channel. For example, the UE may transmit feedback via multiple IRBs of an interlace. The UE may determine which IRBs to use in accordance with a configuration, which may indicate a quantity of IRBs, a distribution of the IRBs, a pattern of the IRBs, or any combination thereof. Additionally, or alternatively, the UE may determine to transmit feedback via multiple IRBs of an interlace that is different from a common interlace.
