- a typical zero-power device is an RFID tag.
- RFID technology is a technology that uses radio frequency signal spatial coupling to realize non-contact automatic transmission and identification of label information.
- RFID tags are also called "radio frequency tags" or “electronic tags”.
- the types of electronic tags classified according to different power supply methods may include active electronic tags, passive electronic tags and semi-passive electronic tags.
- Active electronic tags also known as active electronic tags, means that the energy of the electronic tags is provided by the battery.
- the battery, memory and antenna together constitute an active electronic tag, which is different from the passive radio frequency activation method. Set the frequency band to send information.
- Passive electronic tags also known as passive electronic tags, do not support built-in batteries.
- the tags When passive electronic tags are close to the reader, the tags are in the near-field range formed by the radiation of the reader antenna.
- the electronic tag antenna generates an induced current through electromagnetic induction. , the induced current drives the chip circuit of the electronic label.
- the chip circuit sends the identification information stored in the tag to the reader through the electronic tag antenna.
- Semi-active electronic tags inherit the advantages of small size, light weight, low price and long service life of passive electronic tags.
- the built-in battery supplies power to the RFID chip to increase the reading and writing distance of the tag and improve the reliability of communication.
- the most basic RFID system includes electronic tags (TAG) and readers (Reader/Writer).
- the electronic tag is composed of a coupling component and a chip.
- the electronic tag may include an energy collection module, a backscatter communication module, a low-power computing module and a sensor module.
- Each electronic tag has a unique electronic code, which is placed on the target to achieve the purpose of marking the target object.
- the reader can not only read the information on the electronic tag, but also write the information on the electronic tag, and at the same time provide the electronic tag with the energy required for communication. as shown in picture 2.
- After the electronic tag enters the electromagnetic field it receives the radio frequency signal sent by the reader.
- the passive or semi-passive electronic tag can use the energy obtained from the electromagnetic field generated in the space to transmit the information stored in the electronic tag.
- the reader reads the electronic The information transmitted by the tag and decode it to identify the electronic tag.
- zero-power consumption communication or battery-free communication
- key technologies in zero-power consumption communication are described below.
- the zero-power consumption device receives the carrier signal sent by the backscatter reader, collects energy through the energy harvesting module, and then passes the low-power processing module (the The logic processing module) modulates the incoming wave signal and performs backscattering.
- the terminal does not actively transmit signals, and realizes backscatter communication by modulating the incoming wave signal
- the terminal does not rely on traditional active power amplifier transmitters, and uses low-power computing modules at the same time, which greatly reduces hardware complexity;
- FIG. 4 is a schematic diagram of energy harvesting.
- the energy harvesting module is used to realize the collection of space electromagnetic wave energy through electromagnetic induction, and then realize the driving of the load circuit (low power operation, sensor, etc.), thereby realizing battery-free communication.
- Load modulation is a method often used by electronic tags to transmit data to readers. Load modulation adjusts the electrical parameters of the electronic tag oscillation circuit according to the beat of the data flow, so that the size and phase of the electronic tag impedance change accordingly, thus completing the modulation process.
- Load modulation techniques mainly include resistive load modulation and capacitive load modulation.
- FIG. 5 is a schematic diagram of resistive load modulation.
- a resistor is connected in parallel with the load, which is called a load modulation resistor.
- the resistor is turned on and off according to the clock of the data flow, and the on-off of the switch S is controlled by binary data code.
- a capacitor is connected in parallel to the load, replacing the load modulating resistor in Figure 5 controlled by a binary data code.
- RFID systems typically use one of the following encoding methods: reverse non-return-to-zero (NRZ) encoding, Manchester encoding, unipolar return-to-zero (Unipolar RZ) encoding, differential biphase (DBP) encoding, Differential encoding, pulse interval encoding (PIE), two-way spatial encoding (FM0), Miller (Miller) encoding and differential encoding, etc.
- NRZ reverse non-return-to-zero
- Manchester encoding Manchester encoding
- unipolar return-to-zero (Unipolar RZ) encoding unipolar return-to-zero
- DBP differential biphase
- Differential encoding Differential encoding
- PIE pulse interval encoding
- FM0 two-way spatial encoding
- Miller (Miller) encoding and differential encoding
- the NR system integrates Time Division Duplex (TDD) and Frequency Division Duplex (FDD) working modes to realize a resource configuration structure that takes time slots as cycles.
- TDD Time Division Duplex
- FDD Frequency Division Duplex
- the slot structure of NR is defined as follows:
- Unify the FDD working mode and the TDD working mode do not set an independent working mode, but implement FDD by configuring all Orthogonal Frequency Division Multiplexing (OFDM) symbols as uplink or downlink in the TDD working mode The effect of working mode;
- OFDM Orthogonal Frequency Division Multiplexing
- the number of standardized uplink/downlink resource ratio configurations is increased from 7 to 254 in LTE. This design greatly improves the NR system's support for diversified services;
- flexible (Flexible, F) symbols are also defined for more dynamic downlink/uplink configuration
- the NR system still supports flexible configuration of the time slot format according to actual needs.
- the backscatter communication of the tag is to modulate the carrier signal (which also plays the role of energy supply) sent by the reader, so as to carry information and send it to the reader. That is to say, the backscatter communication from the tag to the reader requires the reader to provide a carrier signal. This itself does not consider the uplink and downlink frame structure.
- the TDD working mode and the FDD working mode are integrated, and the communication in the NR system needs to strictly consider the configuration of uplink and downlink resources.
- the base station transmits signals on downlink resources, and the corresponding label should transmit signals on uplink resources.
- the backscatter communication of the tag requires the reader to provide the carrier signal, that is, the signal transmitted by the tag on the uplink resource also needs the base station to provide the carrier signal, while in the TDD system, the base station can only provide the carrier signal on the downlink resource. Therefore, how to realize the backscatter communication of zero-power devices on the TDD spectrum is an urgent problem to be solved.
- FIG. 6 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 6, the method 200 includes the following content:
- the terminal device receives a signal sent by the first device, where the signal is used to power the terminal device and/or use the terminal device to perform backscatter communication.
- the embodiments of the present application can be applied to a cellular Internet of Things system, such as a cellular passive Internet of Things system, or can also be applied to other scenarios where a terminal device sends information to a network device through zero-power communication or battery-free communication. This application is not limited thereto.
- the zero-power communication method may include the backscatter communication method, or may also include other methods for passive or semi-passive device communication introduced in standard evolution.
- the backscatter communication method for communicating with the network device is taken as an example for illustration, but the present application is not limited thereto.
