Methods, systems, and devices for wireless communications are described in which a first user equipment (UE) may transmit sidelink communications to a second UE, and the second UE may provide feedback associated with the sidelink communication to the first UE in a sidelink control information (SCI) transmission. In some cases, the SCI is first stage SCI transmitted in a sidelink control channel or second stage SCI transmitted in a sidelink shared channel. The feedback may include one or more of acknowledgment/negative-acknowledgment feedback, channel state information feedback, a scheduling request, or any combinations thereof. In some cases, the first UE may indicate resources of the second slot to the second UE for transmission of the feedback in the SCI, such as by providing a time offset value and resource index that identifies the resources.
