Communication based on zero-power devices

In recent years, the application of zero power consumption devices has become more and more widespread. A typical zero power consumption device is a radio frequency identification (Radio Frequency Identification, RFID) device.

RFID equipment is a kind of equipment based on RFID technology. RFID technology is a kind of wireless communication technology. This technology uses radio frequency signal space coupling to realize non-contact automatic transmission and identification of label information. A typical RFID device is an RFID tag, which is also called "radio frequency tag" or "electronic tag". According to the different power supply methods, the types of electronic tags can be divided into active electronic tags, passive electronic tags and semi-passive electronic tags. Among them, active electronic tags, also known as active electronic tags, mean that the energy of the electronic tags is provided by the battery, and the battery, memory and antenna together constitute an active electronic tag, which is different from the activation method of passive radio frequency. Messages are always sent over the set frequency band. Passive electronic tags, also known as passive electronic tags, do not support built-in batteries. When passive electronic tags are close to the reader, the electronic tags are in the near-field range formed by the antenna radiation of the reader. The antenna of the electronic tag passes electromagnetic induction The induced current is generated, and the induced current drives the chip circuit of the electronic tag, and the chip circuit sends the identification information stored in the electronic tag to the reader through the antenna of the electronic tag. Semi-active electronic tags inherit the advantages of small size, light weight, low price and long service life of passive electronic tags. When the reader accesses, 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 RFID system consists of two parts: electronic tags (TAG) and readers (Reader/Writer). Among them, the electronic tag is composed of coupling components and chips. Each electronic tag has a unique electronic code. The electronic tag can be placed on the target object to achieve the purpose of marking the target object. The reader can not only read the information on the electronic tag, but also write information to the electronic tag, and at the same time provide the electronic tag with the energy required for communication. As shown in Figure 2, after the electronic tag enters the electromagnetic field, it receives the radio frequency signal sent by the reader, and the passive electronic tag or passive electronic tag uses the energy obtained by the electromagnetic field generated in the space to transmit the information stored in the electronic tag to read and write. The reader reads the information of the electronic tag and decodes it to identify the electronic tag.

Communication based on zero-power devices, referred to as zero-power communication for short, the key technologies of zero-power communication include energy harvesting, backscatter communication and low-power computing, as shown in Figure 2, the RFID system is a typical zero-power The power consumption communication system includes an electronic tag and a reader-writer, wherein the electronic tag is a zero-power consumption device. The reader emits radio waves to provide energy to the electronic tag. The energy harvesting module installed in the electronic tag can collect the energy carried by the radio wave in the space (the radio wave emitted by the reader is shown in Figure 2), and it is used for the low power consumption calculation module of the electronic tag and for realizing the reflection Scatter communication. After the electronic tag obtains energy, it can receive the control command of the reader and send data to the reader based on the control signaling based on backscatter communication. The data sent by the electronic tag can come from the data stored in the electronic tag itself (such as the identity of the electronic tag or the information pre-written in the electronic tag, such as the production date, brand, manufacturer, etc. of the product). Electronic tags can also be loaded with various sensors, so that the data collected by various sensors can be reported based on the mechanism of zero-power communication.

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

1) Back Scattering Communication (Back Scattering)

Figure 3 is a schematic diagram of backscatter communication. As shown in Figure 3, the reader can also be called a backscatter reader, and the electronic tag can also be called a backscatter tag. Among them, the electronic tag is zero power consumption equipment. The electronic tag receives the carrier signal sent by the reader, collects energy through the energy collection module, and then supplies energy to the low-power computing module (that is, the logic processing module in Figure 3), and uses the low-power computing module to process the incoming wave signal. modulation, and backscatter the modulated signal.

The main features of backscatter communication are as follows:

On the one hand, zero-power devices do not actively transmit signals, and realize backscatter communication by modulating incoming signals;

On the other hand, zero-power devices do not rely on traditional active power amplifier transmitters, and use low-power computing modules to greatly reduce hardware complexity;

In another aspect, the zero-power consumption device combined with the energy harvesting module can realize battery-free communication.

2) Energy harvesting (Power Harvesting)

Figure 4 is a schematic diagram of energy collection, as shown in Figure 4, the radio frequency (RF) module is used to realize the collection of space electromagnetic wave energy through electromagnetic induction, and then realize the drive of the load circuit (such as for low-power computing modules, sensor modules etc.), battery-free communication can also be realized.

3) Load modulation

Load modulation is a method often used by electronic tags to transmit data to readers. Load modulation adjusts the electrical parameters of the oscillating circuit of the electronic tag according to the beat of the data flow, so that the magnitude and phase of the impedance of the electronic tag change accordingly, thus completing the modulation process. There are mainly two types of load modulation techniques: resistive load modulation and capacitive load modulation.

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 and off according to the clock of the data flow, and the on-off of the switch S is controlled by binary data code. The circuit schematic diagram of resistive load modulation is shown in Fig. 5.

In capacitive load modulation, a capacitor is connected in parallel with the load, called the load modulation capacitor, which replaces the load modulation resistor controlled by the binary data code in Figure 5.

4) Coding

The data transmitted by the electronic tag can use different forms of codes to represent binary "1" and "0". 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, 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.

Energizing and triggering signals in zero-power communication systems

1) Power supply signal

The energy supply signal is used to provide energy for zero power consumption devices.

In terms of the carrier of the energy supply signal, the transmitter of the energy supply signal can be a base station, an intelligent gateway, a charging station, a micro base station, a smart phone, etc.

In terms of the frequency band of the power supply signal, the frequency band of the radio wave used as the power supply signal may be low frequency, medium frequency, high frequency, etc.

In addition, the energy supply signal can be a continuous wave or a discontinuous wave (that is, a certain time interruption is allowed).

The energy supply signal can be but not limited to a physical signal specified in the 3GPP standard, such as Sounding Reference Signal (SRS), Physical Uplink Shared Channel (PUSCH), Physical Random Access Channel (Physical Random Access Channel) Random Access Channel (PRACH), Physical Uplink Control Channel (PUCCH), Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Physical Broadcast Channel ( Physical Broadcast Channel, PBCH) etc. Not limited thereto, the energy supply signal may also be a new signal.

2) Trigger signal

The trigger signal is used to trigger the zero-power device to communicate, in other words, the trigger signal is used to schedule the zero-power device.

In terms of the carrier of the trigger signal, the transmitter of the trigger signal can be a base station, an intelligent gateway, a charging station, a micro base station, a smart phone, etc.

The trigger signal may be, but not limited to, a certain physical signal specified in the 3GPP standard, such as SRS, PUSCH, PRACH, PUCCH, PDCCH, PDSCH, PBCH and so on. Not limited to this, the trigger signal may also be a new signal.

Cellular IoT

In the cellular Internet of Things, the terminal equipment is active, and the terminal equipment needs to monitor the scheduling information of the network equipment, and communicate based on the scheduling information of the network equipment. For scheduling-free uplink transmission, terminal devices can communicate on preset resources.

With the increase of 5G industry applications, there will be more and more types of connected objects and application scenarios, and there will be higher requirements for the price and power consumption of terminal equipment. The application of battery-free and low-cost terminal equipment (ie, passive IoT devices) has become a key technology for cellular IoT.

Passive IoT devices can be implemented based on zero-power devices, such as RFID devices, and can be extended on the basis of zero-power devices to apply to cellular IoT. The cellular Internet of Things that introduces passive Internet of Things devices can also be called cellular passive Internet of Things. In the cellular passive Internet of Things, passive Internet of Things devices can communicate by monitoring the scheduling information of network devices. In the embodiment of the present application, the signal carrying the scheduling information of the network device is called a trigger signal. It should be pointed out that the trigger signal is not limited to the signal carrying the scheduling information of the network device, any signal that can trigger the passive IoT device to communicate Any signal can be called a trigger signal.

Different from active devices, passive IoT devices are passive, so before communicating, they need to collect energy, that is, charge, and then communicate.

It should be noted that the terminal device described in the following embodiments of the present application may be a zero-power consumption device, and further, may be a passive Internet of Things device.

Before the terminal equipment communicates, the network equipment is blind to the energy supply and scheduling of the terminal equipment, and invalid energy supply and invalid scheduling may occur, which are specifically reflected in the following aspects.

On the one hand, when both the power supply signal and the trigger signal are sent by the network device, the location of the terminal device is unknown to the network device before the terminal device communicates, because the energy of the power supply signal will decay with distance, The farther the terminal device is from the network device, the longer the charging time will be. The network device does not know the location of the terminal device, nor does it know when the terminal device has collected enough energy for communication, that is, it does not know when the terminal device can receive the trigger signal sent by the network.

On the other hand, the terminal device needs to collect energy before communicating, and the terminal device does not know when the network device sends the trigger signal. If the terminal device keeps monitoring the trigger signal after collecting energy, it will cause waste of power consumption. , especially for terminal devices with low charging efficiency or terminal devices located at the edge of coverage, backscatter communication may be affected due to invalid monitoring of trigger signals.

To this end, the following technical solutions of the embodiments of the present application are proposed. According to the technical solution of the embodiment of this application, different terminal types are distinguished for terminal equipment, and according to the terminal type, it can help network equipment to better supply energy for terminal equipment and schedule terminal equipment, thereby improving energy supply efficiency and scheduling efficiency, and avoiding terminal The device is ineffectively monitoring and demodulating the trigger signal.

In this embodiment of the present application, the network device sends an energy supply signal and/or a trigger signal to at least some of the at least one terminal device based on a terminal type of the at least one terminal device.

Here, the energy supply signal and the trigger signal may come from the same network device, or from different network devices. Further, for the case where the energy supply signal and the trigger signal come from the same network device, the energy supply signal and the trigger signal may be the same physical signal, or the energy supply signal and the trigger signal may also be different physical signal. In the case that the power supply signal and the trigger signal come from the same network device, and the power supply signal and the trigger signal are different physical signals, the network device may send the power supply signal and the trigger signal in time division.

As shown in Figure 7, scenario 1-1 is a communication scenario of cellular direct connection. The base station can send an energy supply signal and a trigger signal to the terminal device. The terminal device is charged through the energy supply signal and communicates with the base station based on the trigger signal. , to send a reverse reflection signal to the base station; Scenario 1-2 is a zero-power consumption wake-up communication scenario, the base station can send an energy supply signal and a trigger signal to the additional module of the terminal device, and the additional module is charged by the energy supply signal, based on the trigger The triggering of the signal communicates with the terminal device, and sends a wake-up signal to the terminal device; scenarios 1-3 are the communication scenarios of the auxiliary function of the cellular direct connection, the micro base station only sends the power supply signal to the terminal device, and the macro base station only sends a trigger to the terminal device Signal, the terminal device is charged by the energy supply signal, communicates with the macro base station based on the trigger signal, and sends a reverse reflection signal to the macro base station.

In some optional implementation manners, the network device sends an energy supply signal and/or a trigger signal to at least some of the at least one terminal device based on the terminal type of the at least one terminal device, including:

The network device divides the at least one terminal device into at least one group based on the terminal type of the at least one terminal device, wherein the terminal devices in the same group have the same terminal type; the network device sends the at least one At least some of the groups send an energizing signal and/or a triggering signal.

Here, the network device uses different transmission parameters for different groups to send the energy supply signal and/or the trigger signal. Optionally, the transmission parameters include at least one of the following: transmit power, beamforming strategy, transmission frequency band, transmission frequency, and transmission duration.

The technical solutions of the embodiments of the present application are illustrated below in conjunction with specific application examples.

Application example one

The terminal type is associated with the receiver sensitivity of the terminal device. For multiple terminal devices working at the same frequency point (that is, the same carrier on the same frequency band), the terminal type of each terminal device is determined according to the receiver sensitivity of the terminal devices. For different types of terminals, the base station uses different transmission parameters to send energy supply signals to these terminal devices. Here, the transmission parameters include at least one of the following: transmit power, beamforming strategy, transmission frequency, and transmission duration.

For example, the terminal type of a terminal device with a receiver sensitivity of -40 dBm is the first terminal type, and the terminal type of a terminal device with a receiver sensitivity of -30 dBm is the first terminal type. It can be seen that the communication coverage distance of the terminal device of the first terminal type is longer, and it is easier to receive the energy supply signal sent by the network device. Compared with the first terminal type, the second terminal type needs to adopt higher transmission power, more concentrated beamforming strategy, more transmission frequency, or more transmission duration to the second terminal type. The device sends an energizing signal.

Application example two

The terminal type is associated with the minimum energy required for the terminal device to communicate. The terminal type of the terminal device whose minimum energy required for the terminal device to communicate is less than the first energy value is the first terminal type. The minimum energy required for the terminal device to communicate is the first terminal type. The terminal type of the terminal device whose minimum energy is greater than the first energy value is the second terminal type. As an example, the first energy value may be zero or close to zero.

In a scenario, the energy supply signal sent by the base station carries scheduling information, and the energy supply signal may also serve as a trigger signal. For the terminal device of the first terminal type, demodulation of the trigger signal during the power supply process is supported, that is, the trigger signal can be demodulated before the power supply process is completed. For terminal devices of the second terminal type, demodulation of the trigger signal during the power supply process is not supported, and the trigger signal needs to be demodulated after the power supply process is completed.

As shown in FIG. 8, the terminal type of UE1 is the first terminal type, and the terminal type of UE2 is the second terminal type. The base station continuously sends the power supply signal and periodically sends the trigger signal. It can be understood that the scheduling information is periodically carried in the in the power supply signal. UE1 has not completed the power supply process at time t2, but UE1 can start to demodulate the trigger signal and communicate with the base station at this time. UE2 needs to complete the energy supply process at time t3, and then demodulates the trigger signal and communicates with the base station. Compared with UE1, UE2 needs to use more transmission frequencies to send trigger signals to UE2. In this way, UE2 can receive trigger signals in time after the power supply process is completed, avoiding wasting energy and doing too much monitoring for trigger signals.

Application Example 3

The terminal type is associated with the radio frequency attribute of the terminal device. Here, the radio frequency attribute includes at least one of the following: number of antennas, maximum operating bandwidth, supported frequency band, and supported frequency band combination.

As an example, the number of antennas supported by the terminal device may be xT/yR, where T represents a transmitting antenna, R represents a receiving antenna, and xT/yR represents x transmitting antennas and y receiving antennas. For example, for a frequency range (Frequency range, FR) 1, the terminal device may support 1T/1R, 1T/2R, and 2T/2R antenna numbers.

As an example, the number of antennas supported by the terminal device may be N antenna arrays (panels), where N is a positive integer. For example, for FR2, the terminal equipment can support 1 antenna array (panels), 2 panels and so on.

As an example, the maximum operating bandwidth supported by the terminal device may be one of the following: 1 MHz, 2 MHz, 5 MHz, 10 MHz, and 20 MHz.

As an example, the terminal device supports a specific frequency band or supports a combination of frequency bands formed by multiple frequency bands.

Assume that UE1 supports frequency band 1 and UE2 supports frequency band 2. According to the frequency bands supported by the terminal equipment, it can be determined that the terminal type of UE1 is the first terminal type, and the terminal type of UE2 is the second terminal type. Then, the base station uses frequency band 1 to send a functional signal to UE1 and/or the trigger signal, and send the function signal and/or the trigger signal to the UE1 by using the frequency band 2.

Application Example 4

The terminal type is associated with the delay requirement corresponding to the energy supply process supported by the terminal device and the delay requirement corresponding to the trigger process supported by the terminal device. For ease of description, the delay requirement corresponding to the energy supply process may also be referred to as the energy supply delay requirement for short, and the delay requirement corresponding to the triggering process may also be referred to as the trigger delay requirement for short. It should be noted that the completion of the energy supply process means that the energy obtained by the terminal device reaches a certain threshold, and the completion of the triggering process means that the terminal device is successfully triggered to communicate. The delay requirement corresponding to the energy supply process refers to the time or the number of cycles consumed from the start to the completion of the energy supply process, and the delay requirement corresponding to the triggering process refers to the time or the number of cycles consumed from the start to the completion of the trigger process.

Here, the energy supply process or the trigger process may be continuous, so the delay requirement corresponding to the energy supply process refers to the time consumed from the start to the completion of the energy supply process, and the delay requirement corresponding to the trigger process refers to the time from the start to the completion of the trigger process. The time it takes to complete. Alternatively, the energy supply process or the trigger process may be periodic, so the delay requirement corresponding to the energy supply process refers to the number of cycles consumed from the start to the completion of the energy supply process, and the delay requirement corresponding to the trigger process refers to the time delay requirement for the trigger process from The number of cycles consumed from start to finish.

As a method, the energy supply delay requirement and trigger delay requirement can be defined uniformly, for example, the total delay requirement corresponding to UE1 is 2s, which means that the sum of the energy supply delay requirement and trigger delay requirement corresponding to UE1 is 2s, For example, the total delay requirement corresponding to UE2 is 1s, which means that the sum of the energy supply delay requirement and trigger delay requirement corresponding to UE2 is 1s.

As another way, the power supply delay requirement and the trigger delay requirement can be defined separately, for example, the corresponding power supply delay requirement of UE1 is 1s and the trigger delay requirement is 2s, for example, the corresponding power supply delay requirement of UE2 is 2s And the trigger delay requirement is 1s.

In addition, the time difference between the energy supply process and the triggering process can also be defined, and different terminal types can be classified according to the time difference. Here, the time difference between the energy supply process and the trigger process may refer to the time difference between the start time of the energy supply process and the start time or completion time of the trigger process, or the time difference between the energy supply process and the trigger process may also refer to the completion of the energy supply process The time difference between the time and the start time or completion time of the triggering process.

Assuming that the delay requirement of UE1 is the first delay requirement, and the delay requirement of UE2 is the second delay requirement, the delay requirement here may include a power supply delay requirement and/or a trigger delay requirement. According to the delay requirement, the terminal type of UE1 is the first terminal type, and the terminal type of UE2 is the second terminal type. The first delay requirement is greater than the second delay requirement. Compared with UE1, UE2, the base station can use greater transmission power, more transmission frequency, and more transmission duration to send the power supply signal to UE2.

Application example five

The terminal type is associated with the charging efficiency of the terminal device. Here, the charging efficiency refers to the time it takes for the terminal device to fully charge a unit of electricity under a unit power and a unit distance.

Different terminal types correspond to different charging efficiencies. For example, the charging efficiency of the first terminal type is: the time it takes for a terminal device to fully charge a unit of electricity under a unit power and a unit distance is: 1 second per W per 10 meters. The charging efficiency of the second terminal type is: the time it takes for the terminal device to fully charge the unit power under the unit power and unit distance is: 3 seconds per W per 10 meters.

Assuming that the charging efficiency of UE1 is 1 second per W per 10 meters, the terminal type of UE1 is the first terminal type; the charging efficiency of UE2 is 3 seconds per W per 10 meters, and the terminal type of UE2 is the second terminal type. Compared with UE1, UE2 can use greater transmit power, more transmission frequency, and more transmission duration to send energy supply signals to UE2.

In this embodiment of the present application, for a terminal device, the terminal device determines its own terminal type; the terminal device receives the power supply signal and/or trigger signal sent by the network device based on its own terminal type, and the power supply signal uses In order to provide energy for the terminal device, the trigger signal is used to trigger the terminal device to perform communication.

Here, optionally, the receiving parameters include at least one of the following: beamforming strategy, receiving frequency band, receiving frequency, and receiving duration.

According to the technical solution of the embodiment of this application, different terminal types are distinguished for terminal equipment, and according to the terminal type, it can help network equipment to better supply energy for terminal equipment and schedule terminal equipment, thereby improving energy supply efficiency and scheduling efficiency, and avoiding terminal The device is ineffectively monitoring and demodulating the trigger signal.
