Methods, systems, and devices for wireless communication are described. For example, a requesting device may transmit a sensor data request message to a responding device. The sensor data request message may include a token identifier associated with the sensor data request message. The requesting device may receive a sensor data response message from the responding device. The sensor data response message may include a first indication of the token identifier at a first layer and a second indication of the token identifier at a second layer. The first layer may be a physical layer that is a lower layer than the second layer. The requesting device may transmit a first feedback message to the responding device and in response to detecting the first indication of the token identifier at the first layer.
