Abstract: Methods, systems, and devices for wireless communication are described. A passive (e.g., ambient Internet of Things (A-loT IoT)) wireless device may receive a continuous wave signal from a Device 275 radio frequency (RF) source that triggers the passive device to measure an RF signal. Based on an amount of energy stored at the passive device, a received power of the signal, or both, the passive device may perform the measurement and transmit a report to a reader, which may forward the report to the RF source. Alternatively, the passive device may transmit a backscattered signal to the reader indicating its inability to perform the measurement, or a request for measurement assistance. The reader may measure a signal strength of the backscattered signal and transmit a corresponding measurement report to the RF source. Accordingly, the RF source may adjust its transmit power or trigger the passive device to switch to a different RF source.
