Methods, systems, and devices for wireless communications are described in which multiple devices may implement sidelink communications for direct device-to-device exchange of information. Such devices (e.g., user equipment (UE) devices) may be configured with resources for sidelink communications, and may monitor for a sidelink preemption indication (SPI) from a base station and determine whether one or more sidelink communications is preempted based on the SPI. The sidelink communications may include a feedback communication that is transmitted using sidelink feedback resources. Based on an indication in a received SPI, it may be determined whether or not to transmit sidelink feedback. The sidelink feedback may be transmitted to one or more other sidelink devices, or to a base station, and preemption of the sidelink feedback may be determined based on one or more parameters associated with the sidelink communications, associated with the SPI, or any combinations thereof.
