[0081] First, the communication technology involved in the embodiments of this application is introduced:

[0082] 1. Introduction to Zero Power Communication

[0083] Zero-power communication can be achieved through the Zero-Power Internet of Things (IoT), which can also be called the Ambient Power Enabled Internet of Things (Ambient IoT / A-IoT) or the Passive IoT.

[0084] Terminal devices that utilize zero-power communication technology are referred to as Ambient IoT Devices (A-IoT Devices). Ambient IoT devices utilize various ambient energies, such as radio frequency energy, light, solar energy, thermal energy, and mechanical energy, to power their operations. Ambient IoT devices can have no energy storage capacity or very limited energy storage capacity, such as using capacitors with a capacity of tens of microfarads (μF). Compared to other IoT devices, Ambient IoT devices offer numerous advantages, including the absence of conventional batteries, maintenance-free operation, compact size, reduced complexity, low cost, and a long lifespan.

[0085] As shown in FIG1 , a schematic diagram of a zero-power communication system 100 provided by an exemplary embodiment of the present application is shown. The zero-power communication system 100 includes a network device 120 and a zero-power device 140 .

[0086] The network device 120 is used to send wireless power supply signals, downlink communication signals and receive backscatter signals from the zero-power device 140 to the zero-power device 140. The zero-power device 140 includes an energy collection module 141, a backscatter communication module 142 and a low-power computing module 143. The energy collection module 141 can collect energy carried by radio waves in space, and is used to drive the low-power computing module 143 of the zero-power device 140 and realize backscatter communication. After the zero-power device 140 obtains energy, it can receive control signaling from the network device 120 and send data to the network device 120 based on the backscattering method according to the control signaling. The sent data can come from data stored in the zero-power device 140 itself (such as an identity identifier or pre-written information, such as the production date, brand, manufacturer, etc. of the product).

[0087] Zero-power device 140 may also include a sensor module 144 and a memory 145. Sensor module 144 may include various sensors, and zero-power device 140 may report data collected by these sensors based on a zero-power mechanism. Memory 145 is used to store basic information (such as item identification) or obtain sensor data such as ambient temperature and humidity.

[0088] The zero-power device 140 itself does not require a battery, and at the same time, the low-power computing module 143 can perform simple signal demodulation, decoding or encoding, modulation and other simple calculation tasks. Therefore, the zero-power module only requires a very simple hardware design, making the zero-power device 140 very low in cost and small in size.

[0089] The network device 120 includes but is not limited to: cellular network devices, such as 5G / 6G network devices, base station devices; WiFi / WLAN network devices, such as access points (APs), routers, mobile access points, etc., and the mobile access point is, for example, a mobile phone.

[0090] The zero-power device 140 includes but is not limited to: handheld devices, wearable devices, vehicle-mounted devices and Internet of Things devices, etc. The zero-power device 140 can be at least one of a mobile phone, a tablet computer, an e-book reader, a laptop computer, a desktop computer, a television, a game console, an augmented reality (AR) terminal, a virtual reality (VR) terminal and a mixed reality (MR) terminal, a wearable device, a handle, an electronic tag and a controller, etc.

[0091] The technical solutions described in some embodiments of the present application can be applicable to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced long term evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-U) system, NR on unlicensed spectrum (NR-U) system, Non-Terrestrial Networks (NTN) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (Wireless Fidelity) system. Fidelity, WiFi), fifth-generation communication (5th-Generation, 5G) system, cellular Internet of Things system, cellular passive Internet of Things system, and can also be applied to subsequent evolution systems of 5G NR system, and can also be applied to 6G and subsequent evolution systems.

[0092] It should be understood that in some embodiments of the present application, "5G" may also be referred to as "5G NR" or "NR".

[0093] It should be understood that in the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0094] 2. Radio Frequency Power Harvesting

[0095] Figure 2 shows the schematic diagram of RF energy harvesting. RF energy harvesting is based on the principle of electromagnetic induction. It uses an RF module (RF) connected in parallel with a capacitor (C) and a load resistor (RL) to harvest electromagnetic wave energy from space. This energy is then used to power zero-power devices, such as low-power demodulators, modulators, sensors, and memory readers. Consequently, zero-power devices do not require traditional batteries.

[0096] 3. Back Scattering

[0097] Figure 3 shows a schematic diagram of the backscatter communication process. Zero-power device 140 receives wireless signal carrier 131 transmitted by network device 120's transmitter (TX) module 121 using amplifier (AMP) 122. It modulates wireless signal carrier 131, loads the information to be transmitted using logic processing module 147, and harvests radio frequency energy using energy harvesting module 141. Zero-power device 140 radiates modulated reflected signal 132 using antenna 146. This information transmission process is called backscatter communication. Network device 120's receiver (RX) module 123 receives modulated reflected signal 132 using low-noise amplifier (LNA) 124. Backscatter and load modulation are closely related. Load modulation achieves this by adjusting and controlling the circuit parameters of the zero-power device 140's oscillator circuit according to the data stream's rhythm, causing parameters such as the electronic tag's impedance to change accordingly.

[0098] Load modulation technology mainly includes resistive load modulation and capacitive load modulation. Figure 4 shows the schematic diagram of resistive load modulation. In resistive load modulation, the load resistor RL is connected in parallel with the third resistor R3, and the switch S based on binary code control is turned on or off. The on and off of the third resistor R3 will cause the voltage on the circuit to change. The load resistor RL maintains a parallel connection relationship with the first capacitor C1, the load resistor RL maintains a series connection relationship with the second resistor R2, and the second resistor R2 maintains a series connection relationship with the first inductor L1. The first inductor L1 is coupled with the second inductor L2, and the second inductor L2 maintains a series connection relationship with the second capacitor C2. Amplitude Shift Keying (ASK) can be achieved, that is, the modulation and transmission of the signal is achieved by adjusting the amplitude of the backscattered signal of the zero-power device. Similarly, in capacitive load modulation, the resonant frequency of the circuit can be changed by turning the capacitor on and off, realizing frequency shift keying (FSK), that is, the modulation and transmission of the signal is achieved by adjusting the operating frequency of the backscattered signal of the zero-power device.

[0099] Zero-power devices utilize load modulation to modulate incoming signals, enabling backscatter communication. These devices offer significant advantages: they don't actively transmit signals, eliminating the need for complex RF links like PAs and RF filters; they don't actively generate high-frequency signals, eliminating the need for high-frequency crystal oscillators; and thanks to backscatter communication, signal transmission doesn't consume the device's own energy.

[0100] 4. Application scenarios of zero-power communication

[0101] Due to its significant advantages such as extremely low cost, extremely low power consumption, and small size, zero-power communication can be widely used in various industries, such as logistics for vertical industries, smart warehousing, smart agriculture, energy and electricity, industrial Internet, etc.; it can also be applied to personal applications such as smart wearables and smart homes.

[0102] For example, it is applied to at least the following four scenarios:

[0103] (1) Object recognition, such as logistics, production line product management, and supply chain management;

[0104] (2) Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of the working environment and natural environment;

[0105] (3) Positioning, such as indoor positioning, intelligent object search, and production line item positioning;

[0106] (4) Intelligent control, such as intelligent control of various electrical appliances in smart homes (turning on and off air conditioners, adjusting temperature), and intelligent control of various facilities in agricultural greenhouses (automatic irrigation and fertilization).

[0107] 5. Encoding method for zero-power communication

[0108] Figure 5 shows a schematic diagram of the encoding method for zero-power communication. The data transmitted by the electronic tag can use different forms of code to represent binary "1" and "0." Wireless radio frequency identification systems typically use one of the following encoding methods: non-return to zero (NRZ) encoding, Manchester encoding, unipolar return to zero (URZ) encoding, differential binary phase (DBP) encoding, Miller encoding, and differential encoding. That is, different pulse signals can be used to represent 0 and 1.

[0109] ·NRZ encoding; Inverse non-return-to-zero encoding uses a high level to represent a binary "1" and a low level to represent a binary "0". Figure 5 shows a level diagram of encoding binary data: 101100101001011 using the NRZ method.

[0110] Manchester encoding: Manchester encoding is also known as split-phase coding. In Manchester encoding, a binary value is represented by a voltage level change (rising or falling) during half a bit period within the bit length. A negative transition during half a bit period represents a binary "1," and a positive transition during half a bit period represents a binary "0." Data transmission errors occur when multiple tags simultaneously transmit data bits with different values, causing the received rising and falling edges to cancel each other, resulting in an uninterrupted carrier signal throughout the entire bit length. Manchester encoding makes it impossible to have an unchanging state within the bit length. The reader can use this error to determine the specific location of the collision. Manchester encoding facilitates data transmission error detection and is commonly used for data transmission from tags to readers when using carrier load modulation or backscatter modulation. Figure 5 shows a schematic diagram of the voltage levels for binary data 101100101001011 encoded using the Manchester method.

[0111] ·URZ encoding; unipolar return-to-zero encoding: a high level in the first half of the bit period represents a binary "1", while a low level signal that lasts throughout the entire bit period represents a binary "1". Figure 5 shows a level diagram of encoding binary data: 101100101001011 using the URZ method.

[0112] DBP encoding: Differential biphase encoding uses any edge within half a bit period to represent a binary "0," while the absence of an edge represents a binary "1." Furthermore, the voltage level is inverted at the beginning of each bit period. This makes the bit beat easier for the receiver to reconstruct. Figure 5 shows the voltage levels of the binary data 101100101001011 encoded using the DBP method.

[0113] Miller coding: In Miller coding, any edge within half a bit period represents a binary "1," while a constant level throughout the next bit period represents a binary "0." The level transition at the beginning of a bit period makes it easier for the receiver to reconstruct the bit beat. Figure 5 shows the level diagram of the binary data 101100101001011 encoded using the Miller method.

[0114] Differential encoding: In differential encoding, each transmitted binary "1" causes a change in the signal level, while for a binary "0" the signal level remains unchanged.

[0115] It should be noted that the above encoding method is an example of an encoding method for zero-power communication, but not a limitation.

[0116] 6. Types of Zero-Power Devices (Based on Energy Source and Usage)

[0117] (1) Passive zero-power devices;

[0118] Zero-power devices do not require internal batteries. When they approach a network device, they are within the near field generated by the network device's antenna radiation. For example, the network device is a reader / writer in a radio frequency identification (RFID) system. Therefore, the zero-power device's antenna generates an induced current through electromagnetic induction, which drives the device's low-power chip circuitry. This enables tasks such as demodulating forward link signals and modulating reverse link signals. For backscatter links, the zero-power device can use backscatter or extremely low-power active transmission to transmit signals. Passive zero-power devices do not require internal batteries for either the forward or reverse link, making them truly zero-power devices. Passive zero-power devices do not require batteries, and their RF and baseband circuits are very simple. For example, they do not require components such as LNAs, PAs, crystal oscillators, and analog-to-digital converters (ADCs). They offer numerous advantages, including small size, light weight, very low price, and a long service life.

[0119] (2) Semi-passive zero-power devices;

[0120] Semi-passive zero-power devices lack conventional batteries. Instead, they use a radio frequency energy harvesting module to harvest radio wave energy and store it in an energy storage unit, typically a capacitor. This energy is then used to power the device's low-power chip circuitry, enabling tasks such as demodulating forward link signals and modulating backward link signals. For backscatter links, the device can transmit signals using either backscatter or extremely low-power active transmission.

[0121] Semi-passive zero-power devices require no internal batteries for either the forward or reverse link. Instead, the energy stored in the capacitors is harvested by the radio energy harvesting module, making them truly zero-power devices. They inherit many of the advantages of passive zero-power devices, including small size, light weight, very low price, and long service life.

[0122] (3) Active zero-power devices;

[0123] Zero-power devices used in some scenarios can also be active zero-power devices, which can have built-in batteries. The battery is used to drive the low-power chip circuit of the zero-power device. This enables tasks such as demodulating forward link signals and modulating reverse link signals. However, for backscatter links, zero-power devices can use backscatter or extremely low-power active transmission to transmit signals. Therefore, the zero-power of active zero-power devices is mainly reflected in the fact that reverse link signal transmission does not consume the zero-power device's own power, but instead uses backscatter. In active zero-power devices, the built-in battery powers the RFID chip, increasing the tag's read and write distance and improving communication reliability. Therefore, they are used in scenarios with relatively high requirements for communication distance and read latency.

[0124] 7. Types of Zero Power Devices (Based on Transmitter Type)

[0125] (1) Zero-power devices based on backscattering;

[0126] These zero-power devices use backscattering, as described above, for uplink data transmission. They lack active transmitters, only backscattering transmitters. Therefore, when these zero-power devices transmit uplink data, they require network equipment to provide a carrier. These zero-power devices use backscattering based on the carrier to achieve uplink data transmission.

[0127] (2) Zero-power devices based on active transmitters;

[0128] These zero-power devices use active transmitters with active transmission capabilities for uplink data transmission. Therefore, when sending uplink data, these zero-power devices can use their own active transmitters to send uplink data without the need for network equipment to provide a carrier. Examples of active transmitters suitable for zero-power devices include ultra-low-power ASK transmitters and ultra-low-power FSK transmitters. Based on current implementations, these transmitters can reduce overall power consumption to 400-600 microwatts when transmitting a 100-microwatt signal.

[0129] (3) Zero-power devices that have both backscatter and active transmitters;

[0130] These zero-power devices can support both backscatter and active transmitters. They can determine whether to use backscatter or active transmitters based on different situations (such as varying battery levels, available ambient energy), or based on network device scheduling.

[0131] 8. Cellular IoT

[0132] Cellular IoT is booming. The 3rd Generation Partnership Project (3GPP) has standardized IoT technologies such as NarrowBand-Internet of Things (NB-IoT), Machine-Type Communications (MTC), and RedCap. However, IoT communication needs in many scenarios remain unmet. For example:

[0133] Harsh communication environment;

[0134] Certain IoT scenarios may encounter extreme environments such as high temperature, extremely low temperature, high humidity, high voltage, high radiation, or high-speed movement. Examples include ultra-high voltage substations, high-speed train track monitoring, environmental monitoring in high-altitude cold regions, and industrial production lines. In these scenarios, existing IoT devices will not function due to the operating environment limitations of conventional power supplies. Furthermore, extreme operating environments are not conducive to IoT device maintenance, such as battery replacement.

[0135] ·Requirement for extremely small terminal form factor;

[0136] Certain IoT communication scenarios, such as food traceability, commodity distribution, and smart wearables, require terminals to be extremely small for ease of use. For example, IoT terminals used for commodity management in the distribution process often use electronic tags, which are embedded in the product packaging in a very compact form factor. Another example is lightweight wearable IoT terminals that can meet user needs while improving the user experience.

[0137] Extremely low-cost IoT communication requirements;

[0138] Many IoT communication scenarios require IoT terminal devices to be sufficiently low-cost to enhance their competitiveness compared to alternative technologies. For example, in logistics or warehousing scenarios, IoT terminal devices can be attached to each item to facilitate the management of large quantities of circulating items. Communication between the IoT terminal device and the logistics network enables precise management of the entire logistics process and lifecycle. These scenarios require IoT terminal devices to be sufficiently competitively priced.

[0139] Therefore, in order to cover these unmet IoT communication needs, cellular IoT also needs to develop ultra-low-cost, extremely small-size, battery-free / maintenance-free IoT, and zero-power IoT can just meet these needs.

[0140] In the application scenario of zero-power communication, zero-power devices can support data reading and data writing, which is used for the receiver to read data from the zero-power device, and for the transmitter or dedicated equipment to write data to the zero-power device.

[0141] For zero-power devices, there is a huge difference in the energy or power consumed when performing data reading and data writing. When reading data from a zero-power device, the energy consumed is very low or a small amount of power is used. However, when writing data to a zero-power device, especially when storing data (for example, using SRAM, NVRAM, etc. to store data to be written), the energy consumed is almost the same as that of other modules remaining in the communication process, which requires higher energy than that required for data reading or uses higher power. For zero-power devices that harvest energy based on RF signals, a very high power needs to be provided by RF when writing data. If the network device simultaneously reads and writes data from the zero-power device, a very high power needs to be provided when writing data, which is difficult to achieve in most application scenarios (for example, long-distance read / write operations).

[0142] How to design data reading and writing for zero-power devices is crucial. The following embodiments illustrate the overall process of data reading and writing for zero-power devices, as well as other designs in the data reading and writing processes.

[0143] First, the names involved in the following embodiments are briefly explained:

[0144] Intermediate node device: A device used to assist network devices in reading and / or writing data to zero-power devices. In some embodiments, the intermediate node device includes at least one of a terminal device, a smartphone, a wireless terminal access device (Customer Premise Equipment, CPE), a base station device, and a handheld device.

[0145] Air interface signaling: signaling used to instruct the zero-power device to read data and / or write data. In the following embodiments, the air interface signaling is named according to whether it indicates data reading or data writing.

[0146] First air interface signaling: air interface signaling used to indicate data reading from a zero-power device. Specifically, it can be: during the process of reading data from a zero-power device, air interface signaling sent by a network device to a zero-power device, air interface signaling sent by a network device to an intermediate node device, and air interface signaling sent by an intermediate node device to a zero-power device. It should be understood that the communication links corresponding to the first air interface signaling involved in different sending steps may be the same or different, and the information carried by the first air interface signaling may be the same, partially the same, or completely different.

[0147] Second air interface signaling: air interface signaling used to indicate data writing to a zero-power device. Specifically, it can be: in the process of writing data to a zero-power device, air interface signaling sent by a dedicated device to a zero-power device, air interface signaling sent by a network device to a zero-power device, air interface signaling sent by a network device to an intermediate node device, and air interface signaling sent by an intermediate node device to a zero-power device. It should be understood that the communication links corresponding to the second air interface signaling involved in different sending steps may be the same or different, and the information carried by the second air interface signaling may be the same, partially the same, or completely different.

[0148] First data: device data reported by the zero-power device, which may specifically be: data sent by the zero-power device to the network device, data sent by the zero-power device to the intermediate node device, or data forwarded by the intermediate node device to the network device during data reading from the zero-power device.

[0149] Second data: Data written directly to the zero-power device by a dedicated device, or data written to the zero-power device by an intermediate node device after the network device coordinates with the intermediate node device. Specifically, this can be: during the data writing process, the dedicated device writes data to the zero-power device; or, alternatively, the network device and / or the intermediate node device initiates the data write, and the network device coordinates with the intermediate node device, and the intermediate node device writes data to the zero-power device.

[0150] Third data: Data written to the zero-power device by the intermediate node device when the network device and the intermediate node device jointly write data to the zero-power device. Specifically, this may be data written to the zero-power device by the intermediate node device when the network device and / or the intermediate node device initiates data writing, the network device and the intermediate node device jointly write data to the zero-power device, and data written to the zero-power device by the intermediate node device.

[0151] Fourth data: Data written by the network device to the zero-power device when the network device and the intermediate node device jointly write data to the zero-power device. Specifically, this may be data written by the network device to the zero-power device when the network device and / or the intermediate node device initiates data writing, and the network device and the intermediate node device jointly write data to the zero-power device.

[0152] Feedback messages: Also known as feedback information, these messages indicate the results of reading and / or writing data to a zero-power device. These messages may include feedback messages sent by a zero-power device to a network device, feedback messages sent by a zero-power device to an intermediate node device, and feedback messages forwarded by an intermediate node device to a network device.
