DETAILED DESCRIPTION

The present disclosure will be described in detail below with reference and accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and the features in the present disclosure can be combined without conflict.

It should be noted that the terms “first”, “second”, etc. in the descriptions and claims of this disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessary to describe a specific order or sequence.

In recent years, zero-power-consumption communication technology has developed rapidly, in which the key technologies of zero-power-consumption communication include power harvesting, back scattering communication, and low-power-consumption computing. FIG. 1 is a schematic view of zero-power-consumption communication according to some embodiments of the present disclosure. As shown in FIG. 1, a typical zero-power-consumption communication system includes a reader and a zero-power-consumption device. The reader transmits radio waves for providing power to the zero-power-consumption device. An RF power harvesting module installed in the zero-power-consumption device may harvest the power carried by the radio waves in space (the radio waves transmitted by the reader are shown in FIG. 1) for driving a low-power-consumption computing module of the zero-power device and realizing the back scattering communication. After the zero-power-consumption device obtains the power, it may receive the read-write control command and send the data to the read-write based on the control signaling through the backward scattering way. The sent data may come from the stored data in zero-power-consumption device itself (such as identity marks or pre-written information, for example, the production date of goods, brand, manufacturer, etc.). The zero-power-consumption device may also load all kinds of sensors, thus data collected by all kinds of sensors is reported based on the zero-power-consumption mechanism. As can be seen, the zero-power-consumption device itself does not need a battery, while the use of low-power-consumption computing module may achieve simple signal demodulation, decoding or coding, modulation, and other simple computing work, therefore the zero-power-consumption module only requires minimal hardware design, making the zero-power-consumption device very low cost and small size.

FIG. 4 is a schematic view of a zero-power-consumption communication system based on cellular communication provided in some embodiments of the present disclosure. The disclosure is used in scenarios 1-3.

Scenario 1: Network Device is Directly Connected to a Zero-Power Device.

In this scenario, the communication device may be a network device (e.g., a base station) of a cellular system. The zero-power-consumption device is powered and triggered by the network device. The zero-power-consumption device sends a back scattering signal to the network device after it has received enough power and a trigger signal.

The specific process is as follows:

- Step 1: The network device sends a power supply signal to the zero-power device for supplying power to the zero-power-consumption device.
- Step 2: The network device sends a trigger signal to the zero-power-consumption device.
- Step 3: Based on the trigger signal and the power supply signal, the zero-power-consumption device sends a back scattering signal to the network device.

In some embodiments, a time delay between sending the power supply signal by the network device and sending the trigger signal by the network device is a preset value or a configurable value; a time delay between receiving the trigger signal by the zero-power-consumption device and sending the back scattering signal by the zero-power-consumption device is a preset value, or configured by the network device and informed to the zero-power-consumption device.

The network device may send the trigger signal to the zero-power-consumption device after a TO time delay of sending the power supply signal to the zero-power-consumption device.

The zero-power-consumption device may proceed back scattering communication to the network device after a T1 time delay of receiving the trigger signal.

Specifically, TO may be a preset fixed value, i.e., mutually negotiated in advance between the network device and the zero-power-consumption device. It can also be a configurable value, which can be, for example, a value associated with at least one of the communication distance, carrier frequency, and power of the supply/trigger signal emission. In the case of configuration, the network device may carry the configured value in the power supply signal. It can also be sent to the zero-power-consumption device by means of another signaling (e.g., among cellular systems, it can be radio link control RRC signaling, media access control unit MAC CE, and downlink control information DCI).

Specifically, T1 can be a preset fixed value, i.e., mutually negotiated in advance between the network device and the zero-power-consumption device. It can also be a configurable value, which can be, for example, a value associated with at least one of the communication distance, carrier frequency, power of supply/trigger signal emission, etc. In the case of configuration, the network device may carry the configured value in the power supply and/or trigger signal. It can also be sent to the zero-power-consumption device by means of other signals (e.g., radio link control RRC signaling, downlink control information DCI, and side-channel control information SCI).

Scenario 2: A Multi-Device Module Containing Zero-Power-Consumption Devices.

The zero-power-consumption device is combined with other devices and used as a module of other devices. Here, the zero-power device is used as a sleeping/wake-up module of the intelligent terminal an example. The power supply and communication trigger of the zero-power-consumption device is undertaken by the network device. After obtaining enough power and receiving the trigger signal, the zero-power-consumption device uses backscattering to send a sleeping signal or wake-up signal to the intelligent terminal, which in turn makes sleep or wakes up the intelligent terminal device.

The specific process is as follows:

- Step 1: The network device sends a power supply signal to the zero-power-consumption device for supplying power to the zero-power-consumption device.
- Step 2: The network device sends a trigger signal to the zero-power device.

It can also be a configurable value, which can be, for example, a value associated with the communication distance, carrier frequency, and power of supply/trigger signal transmission. In the case of configuration, the network device may carry the configured value in the power supply signal. It can also be sent to the zero-power-consumption device by means of another signaling (e.g., among cellular systems, it can be radio link control RRC signaling, media access control unit MAC CE, and downlink control information DCI).

Specifically, T3 can be a preset fixed value, i.e., mutually negotiated in advance between the network device and the zero-power-consumption device. It can also be a configurable value, which can be, for example, a value associated with the communication distance, carrier frequency, power of supply/trigger signal transmission, etc. In the case of configuration, the network device may carry the configured value in the power supply and/or trigger signal. It can also be sent to the zero-power-consumption device by means of other signals (e.g., radio link control RRC signaling, downlink control information DCI, and side-channel control information SCI).

For example, the power supply signal is sent through the network device, and the trigger signal is sent from other devices. Another example is that the power supply signal is sent through the terminal device and the trigger signal is sent from other devices.

- Step 2: The network device sends a trigger signal to the zero-power-consumption device.
- Step 3: Based on the trigger signal and the power supply signal, the zero-power-consumption device sends a back scattering signal to the network device.

Specifically, the first communication device includes at least one of the following: a base station, a relay device, a charging station, other smart terminal, etc.

In some embodiments, it is also possible for the network device to supply power to the zero-power-consumption device and for the first communication device to trigger the zero-power-consumption device to send a back scattering signal to the network device.

In some embodiments, the time delay between the zero-power-consumption device receiving the trigger signal and sending the back scattering signal is a preset value, or configured by the network device and informed to the zero-power-consumption device.

In some embodiments, the network device may send the trigger signal to the zero-power-consumption device by the first communication device after a T4 time delay of sending the power supply signal to the zero-power-consumption device.

The zero-power-consumption device may proceed back scattering communication to the network device after a time delay of T5 of receiving the trigger signal.

Specifically, T4 may be a preset value, i.e., a pre-negotiated tripartite determination by the network device, the first communication device, and the zero-power-consumption device. It can also be a configurable value, which can be, for example, a value associated with the communication distance, carrier frequency, power of supply/trigger signal transmission, etc. In the case of configuration, the network device can carry the configured value in the power supply signal. It can also be sent to the zero-power-consumption device and the first communication device by means of other signaling (for example, among cellular systems, it can be radio link control RRC signaling, media access control unit MAC CE, and downlink control information DCI), and also determined by the measurement results of the terminal device.

Specifically, T5 may be a preset value, i.e., determined in advance by mutual agreement between the first communication device and the zero-power-consumption device. It can also be a configurable value, which can be, for example, a value associated with the communication distance, carrier frequency, power of supply/trigger signal transmission, etc. In the case of configuration, the network device may carry the configured value in the power supply signal. It can also be sent to the zero-power-consumption device by means of other signaling (e.g., among cellular systems, it can be radio link control RRC signaling, media access control unit MAC CE, and downlink control information DCI), and it can also be determined by the measurement results of the terminal device and sent to the zero-power-consumption device by means of sidelink control information SCI.

The power supply and communication trigger of the zero-power-consumption device are both undertaken by the same intelligent terminal (e.g., smartphone), and the zero-power-consumption device uses backscattering to send signals to the intelligent terminal after obtaining sufficient power and receiving the trigger signal.

The specific process is as follows:

- Step 1: The terminal device sends a power supply signal to the zero-power-consumption device for supplying power to the zero-power-consumption device.
- Step 2: The terminal device sends a trigger signal to the zero-power-consumption device.
- Step 3: Based on the trigger signal and the power supply signal, the zero-power-consumption device sends a back scattering signal to the terminal device for communication.

In some embodiments, a time delay between the terminal device sending the power supply signal and sending the trigger signal is a preset value, or, a configurable value; the time delay between the zero-power-consumption device receiving the trigger signal and sending the back scattering signal is a preset value, or, the time delay is configured by the terminal device and informed to the zero-power-consumption device.

It can also be a configurable value, which can be, for example, a value associated with the communication distance, carrier frequency, power of supply/trigger signal transmission, etc. In the case of configuration, the terminal device may carry the configured value in the power supply signal. It can also be sent to the zero-power-consumption device by means of other signaling (e.g., in a cellular system, the terminal sends a radio link control RRC signaling, media access control unit MAC CE, and downlink control information DCI based on the network).

Specifically, T7 can be a preset fixed value, i.e., determined in advance by mutual agreement between the terminal device and the zero-power-consumption device.
