Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive a sidelink message from a second UE via one or more sidelink resources. The first UE may select a sidelink shared channel resource to use for transmission of feedback information associated with the sidelink message. The selecting may be based on one or more conditions and may be between the sidelink shared channel resource and a sidelink feedback channel resource. The first UE may transmit the feedback information to the second UE via at least the sidelink shared channel resource.
