Abstract
Provided is a position method. The method is performed by a positioning device. The method includes: positioning a zero-power tag device based on a first radio signal from the zero-power tag device; wherein the first radio signal is actively transmitted by the zero-power tag device in response to the zero-power tag device receiving a second radio signal, or the first radio signal is passively transmitted via backscatter modulation on the second radio signal; wherein the second radio signal is used to energize the zero-power tag device or wake up the zero-power tag device.
Claims20
A positioning method, performed by a positioning device, the method comprising:
- positioning a zero-power tag device based on a first radio signal from the zero-power tag device;
- wherein the first radio signal is actively transmitted by the zero-power tag device in response to the zero-power tag device receiving a second radio signal, or the first radio signal is passively transmitted via backscatter modulation on the second radio signal;
- wherein the second radio signal is used to energize the zero-power tag device or wake up the zero-power tag device.
A positioning device, comprising:
- a processor, a memory, and a transceiver;
- wherein the memory stores one or more computer programs, which when executed by the processor, causes the positioning device to:
- position a zero-power tag device based on a first radio signal from the zero-power tag device;
- wherein the first radio signal is actively transmitted by the zero-power tag device in response to the zero-power tag device receiving a second radio signal, or the first radio signal is passively transmitted via backscatter modulation on the second radio signal;
- wherein the second radio signal is used to energize the zero-power tag device or wake up the zero-power tag device.
A zero-power tag device, comprising:
- a processor, a memory, and a transceiver;
- wherein the memory stores one or more computer programs, which when executed by the processor, causes the zero-power tag device to:
- in response to receiving a second radio signal, actively transmit a first radio signal, or passively transmit the first radio signal via backscatter modulation on the second radio signal;
- wherein the first radio signal is configured for a positioning device to position the zero-power tag device, and the second radio signal is used to energize to the zero-power tag device or wake up the zero-power tag device.
