When the zero-power terminal is powered and enters the coverage of the zero-power network, it will communicate with the network side.

Principles of Zero Power Communication Technology

Zero Power (Zero Power) communication uses energy harvesting and backscatter communication technology. The zero-power communication system consists of network devices and zero-power terminals, as shown in Figure 2. Among them, the network device is used to send an energy supply signal (that is, a radio wave) and a downlink communication signal to the zero-power terminal, and receive backscattered signals from the zero-power terminal. As an example, the zero-power terminal includes an energy harvesting module, a backscatter communication module, and a low-power computing module. In addition, the zero-power consumption terminal may also be equipped with memory and/or sensors, the memory is used to store some basic information (such as item identification, etc.), and the sensor is used to obtain sensing data such as ambient temperature and ambient humidity.

The key technologies of zero-power communication are further described below.

(1) Energy harvesting (Power Harvesting)

Figure 3 is a schematic diagram of energy harvesting. As shown in Figure 3, the energy harvesting module realizes the collection of space electromagnetic wave energy based on the principle of electromagnetic induction, and then obtains the energy required to drive the zero-power consumption terminal to drive the load circuit ( Such as drivers for low-power computing modules, sensors, etc.). Therefore, the zero-power terminal does not need a traditional battery, and realizes battery-free communication.

As an example, the energy collection module refers to a radio frequency energy collection module, and the radio frequency energy collection module can collect energy carried by radio waves in space to realize the collection of space electromagnetic wave energy.

(2) Back Scattering Communication (Back Scattering)

Figure 4 is a schematic diagram of backscatter communication. As shown in Figure 4, the zero-power terminal receives the wireless signal sent by the network device (that is, the carrier wave in Figure 4), and modulates the wireless signal, that is, loads the wireless signal on the wireless signal. The information that needs to be sent and the modulated signal is radiated from the antenna. This information transmission process is called backscatter communication.

The functions of backscatter communication and load modulation are inseparable, and load modulation is a method often used by zero-power terminals to load information. Load modulation adjusts and controls the circuit parameters of the oscillation circuit of the zero-power terminal according to the beat of the data flow, so that the magnitude and/or phase of the impedance of the zero-power terminal changes accordingly, thereby completing the modulation process. The load modulation technology mainly includes resistive load modulation and capacitive load modulation.

As shown in Figure 5, in resistive load modulation, a resistor is connected in parallel with the load, which is called a load modulation resistor. The resistor is turned on or off based on the control of the binary data flow. Amplitude keying modulation (ASK), that is, signal modulation is realized by adjusting the amplitude of the backscattered signal of the zero-power terminal. Similarly, in capacitive load modulation, a capacitor is connected in parallel with the load, which is called a load modulation capacitor. This capacitor replaces the load modulation resistor in Figure 5. The circuit resonant frequency can be changed by switching the capacitor on and off, thus realizing frequency keying modulation. (FSK), that is, the modulation of the signal is realized by adjusting the working frequency of the backscattered signal of the zero-power terminal.

It can be seen that the zero-power terminal performs information modulation on the incoming signal by means of load modulation, thereby realizing the backscatter communication process. Therefore, the zero-power terminal has the following significant advantages: On the one hand, the zero-power terminal does not actively transmit signals, so it does not require complex radio frequency links, such as power amplifiers and radio frequency filters. On the other hand, zero-power terminals do not need to actively generate high-frequency signals, so high-frequency crystal oscillators are not required. On the other hand, the zero-power terminal communicates through backscattering, and the transmission process does not need to consume the energy of the zero-power terminal itself.

Coding method for zero-power communication

The data transmitted by the zero-power terminal can use different forms of codes to represent binary "1" and "0". Radio frequency identification systems usually use one of the following encoding methods: reverse non-return zero (NRZ) encoding, Manchester encoding, unipolar RZ encoding, differential biphase ( DBP) coding, Miller coding, and differential coding. Using different forms of codes to represent binary "1" and "0" can also be understood as representing 0 and 1 with different pulse signals. Several numbering methods are described below.

(1) Reverse non-return-to-zero encoding

The reverse non-return-to-zero encoding uses a high level to represent a binary "1", and a low level to represent a binary "0", as shown in Figure 6.

(2) Manchester encoding

Manchester encoding is also known as Split-Phase Coding. In Manchester encoding, the value of a certain bit is represented by the change (rise/fall) of the level during half a bit period within the bit length, and a negative transition during half a bit period represents a binary "1". A positive transition at half a bit period represents a binary "0", as shown in Figure 7.

Manchester encoding is usually used for data transmission from a zero-power terminal to a network device when carrier load modulation or backscatter modulation is used, because it is beneficial to discover errors in data transmission. This is because the "no change" state is not allowed within the bit length. When the data bits sent by multiple zero-power terminals at the same time have different values, the rising and falling edges of the reception cancel each other out, resulting in an uninterrupted carrier signal within the entire bit length. Since this state is not allowed, the network device uses This error can determine the specific location of the collision.

(3) Unipolar return-to-zero coding

The high level of the unipolar return-to-zero code in the first half bit period represents a binary "1", and the low level signal that lasts for the entire bit period represents a binary "0", as shown in Figure 8. Unipolar return-to-zero coding can be used to extract bit synchronization signals.

(4) Differential bi-phase encoding

Any edge of the differential biphase encoding in half a bit period represents a binary "0", and no edge is a binary "1", as shown in FIG. 9 . In addition, the levels are inverted at the beginning of each bit period. Therefore, bit beats are relatively easy to reconstruct for the receiving end.

(5) Miller (Miller) coding

Any edge of the Miller code in half a bit period represents a binary "1", and a constant level in the next bit period represents a binary "0". A level transition occurs at the beginning of a bit period, as shown in Figure 10. Thus, bit beats are easier for the receiver to reconstruct.

(6) Differential coding

In differential encoding, each binary "1" to be transmitted causes a change in signal level, whereas for a binary "0" the signal level remains unchanged.

Classification of Zero Power Terminals

Based on the energy sources and usage methods of zero-power terminals, zero-power terminals can be divided into the following types:

(1) Passive zero power consumption terminal

The zero-power terminal does not need a built-in battery. When the zero-power terminal is close to the network device, the zero-power terminal is within the near-field range formed by the antenna radiation of the network device. Therefore, the antenna of the zero-power terminal generates an induced current through electromagnetic induction. The current drives the low-power computing module (that is, the low-power chip circuit) of the zero-power terminal to work, to realize the demodulation of the forward link signal and the signal modulation of the backward link. For the backscatter link, the zero-power terminal uses the backscatter implementation to transmit signals.

It can be seen that the passive zero-power terminal does not need a built-in battery to drive it, whether it is a forward link or a reverse link, and is a real zero-power terminal.

Since the passive zero-power terminal does not require a battery, the radio frequency circuit and baseband circuit of the passive zero-power terminal are very simple, such as no low-noise amplifier (LNA), power amplifier (PA), crystal oscillator, ADC, etc., so It has many advantages such as small size, light weight, cheap price and long service life.

(2) Semi-passive zero-power consumption terminal

The semi-passive zero-power terminal itself does not install a conventional battery, but can use an energy harvesting module to collect radio wave energy, and store the collected energy in an energy storage unit (such as a capacitor). After the energy storage unit obtains energy, it can drive the low-power computing module (that is, the low-power chip circuit) of the zero-power terminal to work, realize the demodulation of the forward link signal, and the signal modulation of the backward link, etc. Work. For the backscatter link, the zero-power terminal uses the backscatter implementation to transmit signals.

It can be seen that the semi-passive zero-power terminal does not need a built-in battery to drive either the forward link or the reverse link. Although the energy stored in the capacitor is used in the work, the energy comes from the radio collected by the energy harvesting module. Wave energy, so it is also a true zero-power consumption terminal.

Semi-passive zero-power terminals inherit many advantages of passive zero-power terminals, so they have many advantages such as small size, light weight, cheap price, and long service life.

(3) Active Zero Power Terminal

The zero-power consumption terminal used in some scenarios can also be an active zero-power consumption terminal, and this type of terminal can have a built-in battery. The battery is used to drive the low-power computing module (that is, the low-power chip circuit) of the zero-power terminal to realize the demodulation of the forward link signal and the signal modulation of the backward link. But for the backscatter link, the zero-power terminal uses the backscatter implementation to transmit the signal. Therefore, the zero power consumption of this type of terminal is mainly reflected in the fact that the signal transmission of the reverse link does not require the power of the terminal itself, but uses backscattering.

Active zero-power consumption terminal, the built-in battery supplies power to the RF chip to increase the communication distance and improve the reliability of communication. Therefore, it can be applied in some scenarios that require relatively high communication distance and communication delay.

Cellular Passive IoT

With the increase of industrial applications, there are more and more types of connected objects and application scenarios, and there will be higher requirements for the price and power consumption of communication terminals. The application of battery-free and low-cost passive IoT devices has become a key technology of cellular IoT, enriching the types and quantities of network link terminals and truly realizing the Internet of Everything. Among them, passive IoT devices can be based on zero-power communication technology, such as radio frequency identification (Radio Frequency Identification, RFID) technology, and extended on this basis to be suitable for cellular IoT.

Zero-power terminals need to collect the energy of radio waves sent by network devices, and can drive themselves to work after obtaining energy. Therefore, before obtaining energy, the zero-power terminal is in the "off" state, that is, it cannot receive signals sent by network devices at this time, nor can it send signals to network devices.

Since the zero-power terminal has the characteristics of limited energy supply, small amount of transmitted data, and limited processing capacity, the communication system requirements are simple and applicable.

Figure 11 is the first architecture diagram of the zero-power communication system provided by the embodiment of the present application. As shown in Figure 11, the system includes at least one of the following: zero-power terminals, access network nodes, core network nodes, and data center nodes and service control nodes; where,

In case 3, the micro access network node (such as a micro base station) only sends an energy supply signal to a zero-power terminal, and the macro access network node (such as a macro base station) only sends a trigger signal to a final zero-power terminal. The terminal is charged through the energy supply signal, communicates with the macro access network node based on the trigger signal, and sends a reverse reflection signal to the macro access network node. Case 3 is applicable to the communication scenario of the auxiliary function of the cellular direct connection.

It can be seen from FIG. 12 that the access network node that supplies energy for the zero-power consumption terminal and the access network node that communicates with the zero-power consumption terminal may be the same or different. For example, in case 1, the access network node that supplies energy for the zero-power terminal is the same as the access network node that communicates with the zero-power terminal; for example, in case 3, the access network node that supplies energy for the zero-power terminal It is different from the access network node communicating with the zero power consumption terminal. In order to improve the coverage and energy supply efficiency of energy supply, access network nodes dedicated to energy supply can be deployed (such as case 3). In addition, conventional terminals can also be used to supply energy for zero-power terminals and integrate with zero-power consumption The terminal communicates (as in case 2).

Based on the above description, the zero-power terminal needs to collect radio waves to obtain energy before it can drive itself to work. Therefore, before obtaining energy, the zero-power terminal is in the "off" state, that is, in the off-grid state. In addition, for a zero-power communication system, the network deployment may be an island coverage method, which cannot achieve full coverage, so zero-power terminals will be offline because there is no network coverage. For zero-power terminals, due to limited energy supply and limited network coverage, they may often be in an off-grid state. When the zero-power terminal is powered and enters the coverage of the zero-power network, if it needs to communicate with the network side, due to the limited power of the zero-power terminal, there may be insufficient temporary energy supply, so fast access The network is good for energy saving of zero-power terminals and fast completion of the communication process.

To this end, the following technical solutions of the embodiments of the present application are proposed. The technical solutions of the embodiments of the present application may be applied to, but not limited to, the zero-power communication system shown in FIG. 11 or FIG. 12 .

"A relationship in which multiple uplink radio resources correspond to one downlink radio resource" may also be understood as a "many-to-one relationship".

Application Example 4

In a zero-power system, in order to compensate for the data arrival delay caused by the transmission delay, TA can be introduced, or a sufficiently large cyclic prefix (Cyclic Prefix, CP) or guard band can be reserved. For the method of reserving CP or guard band, it is necessary to increase the complexity of data detection on the network side, and the spectrum efficiency is low.
