Measurement relaxation and measurement assistance for passive wireless devices

An apparatus for wireless communication at a first wireless device, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit, to a passive wireless device, a continuous wave signal, the continuous wave signal triggering the passive wireless device to perform a measurement of a signal transmitted by the first wireless device or by a second wireless device in a RF resource;
• receive a report indicating the measurement of the signal in the RF resource;
• and
• transmit a second continuous wave signal at an increased power level or a control message indicating that the passive wireless device is to switch to a different RF wireless device as a source for continuous wave signal transmissions based at least in part on the report.

An apparatus for wireless communication at a second wireless device, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, via a backscatter link, a backscattered signal indicating an inability of a passive wireless device to perform a RF resource measurement of a signal transmitted by a first wireless device;
• perform a signal strength measurement of the backscattered signal;
• and
• transmit, to the first wireless device, a report indicating the signal strength measurement of the backscattered signal.
