Backscatter communications (Backscatter Communication, BSC)

Backscatter communication refers to the transmission of its own information by signal modulation of radio frequency signals in other devices or environments by a backscatter communication device. A backscatter communication device (hereinafter BSC device) may be:

(1) BSC devices in traditional RFID, typically a Tag (Tag), belong to Passive IoT devices (Passive-IoT)

(2) Semi-passive (semi-passive) tags, the downstream receiving or upstream reflecting of such tags has a certain amplifying capability;

(3) Tag (Active Tag) with active transmission capability, can transmit information to a Reader without depending on reflection of an incident signal;

With particular reference to fig. 1a and 1b, where fig. 1a shows a schematic diagram of a backscatter communication system and fig. 1b shows a schematic diagram of the backscatter communication principle

A simple implementation is that when a Tag needs to send a '1', the Tag reflects the incoming carrier signal and when the Tag needs to send a '0', it does not.

The backscatter communication device controls the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal, effecting modulation of the signal. Wherein the reflection coefficient of the signal can be characterized as:

where Z ₀ is the antenna characteristic impedance and Z ₁ is the load impedance. Assuming that the incident signal is S _in (t), the output signal is Thus, by reasonably controlling the reflection coefficient, a corresponding amplitude modulation, frequency modulation or phase modulation can be achieved. The architecture of typical backscatter communications can be divided into single-base systems and dual-base systems.

Single base system

Fig. 1c shows a monostatic backscatter communication system, typically a conventional RFID system, which includes BSC devices (e.g., tags) and readers. The reader/writer includes an RF radio frequency source for generating an RF radio frequency signal (also referred to as an excitation signal, typically a Continuous Wave (CW)) to power the BSC apparatus and provide a carrier Wave, and a BSC receiving end. The BSC equipment modulates and backscatter CW, and the BSC receiving end in the reader-writer receives the backscatter signal and then demodulates the signal. Because the RF source and the BSC receiving end are in the same device, such as a reader-writer herein, it is known as a single-base backscatter communication system. In this system, since the RF radio frequency signal transmitted from the BSC apparatus is subjected to the double near-far effect caused by the signal attenuation of the round trip signal, the energy attenuation of the signal is large, and thus the single-base system is generally used for short-range backscatter communication such as conventional RFID applications.

Dual base system

Unlike the single-base system, the RF source and BSC receiver in the dual-base system are separate, as shown in the schematic diagram of fig. 1 d. Thus, the bistatic system avoids the problem of large round trip signal attenuation, and further improves the performance of the backscatter communication system by reasonably locating the RF source.

Backscattering communication system under cellular networking

In cellular networks, the backscatter communication system can be specifically divided into 8 architectures as shown in table 1 and fig. 1d below, from the differences in RF radio frequency sources, uplink, downlink.

TABLE 1

In architecture 1, the base station is an RF radio frequency source at this time, and is also a downlink transmitting end (i.e., a control command transmitting end) of the BSC apparatus and an uplink receiving end (i.e., a BSC receiving end) of the BSC apparatus, i.e., the base station directly communicates with the BSC apparatus at this time. (note that this deployment architecture requires high receive sensitivity for base stations and BSC devices, but is simple to deploy).

In architecture 2, the base station is also an RF source, but there is a Relay for relaying the uplink from the BSC device to the base station, although the Relay may Relay the downlink from the base station to the BSC device, which is not shown here.

In architecture 3, the UE is used for RF radio sources, downlink and uplink forwarding BSC devices to base stations.

In the uplink, BSC equipment sends back scattering signal to UE first, and then the signal is forwarded to base station by UE;

the architecture 3-2a is that a base station is an RF radio frequency source, the base station firstly transmits downlink data to UE and then the UE forwards the downlink data to BSC equipment, and in an uplink, the BSC equipment directly transmits a back scattering signal to the base station;

the architecture 3-2b is that UE is an RF radio frequency source, a base station firstly transmits downlink data to the UE and then the downlink data is forwarded to BSC equipment by the UE, and in an uplink, the BSC equipment directly transmits a back scattering signal to the base station;

The construction 3-3a is that the base station is RF source, the base station firstly transmits downlink data to UE, then the UE transmits the downlink data to BSC equipment, and in the uplink, the BSC equipment transmits back scattering signal to the UE, and then the UE transmits the back scattering signal to the base station;

in the uplink, BSC equipment sends back scattering signals to UE, and then the UE forwards the back scattering signals to the base station;

type of RFID sensor tag

The current classification methods of RFID tag sensors can be broadly divided into two major categories, chip-equipped and Chipless (Chip). Electronic sensors that integrate the sensor directly into a conventional RFID tag are a major representative of the former, while electromagnetic sensors that rely on differences in electromagnetic response caused by antenna detuning to deliver a perceived amount are a major representative of the latter.

Electronic RFID sensor

Fig. 1f shows the distinction between electronic and electromagnetic sensors, wherein fig. 1f is a schematic diagram of an electronic RFID sensor on the left side and fig. 1f is a schematic diagram of an electromagnetic RFID sensor on the right side. It can be seen that the sensing unit of the former needs to interact with the chip, while the sensing amount of the latter directly reacts on the frequency response variation of the tag.

The on-chip RFID sensor may be further subdivided into active sensor tags (Active Sensor Tags), battery-assisted sensor tags (Battery Assisted Sensor Tags), passive sensor tags (Battery-Less/Passive Sensors).

As the name implies, the active sensing tag is to integrate the sensor on the active tag, and the chip mounted on the tag can acquire sensing information from the sensing unit, then convert the sensing information into bit information capable of being transmitted, and modulate the bit information on an autonomously generated carrier wave for transmission. The tag has the advantages of long communication distance, high power consumption, battery replacement and high cost.

The battery-assisted sensor tag operates similarly to the active sensor tag, but differs in that it cannot autonomously generate a carrier wave, but rather relies on an external carrier wave. Such tags have the advantage of low power consumption and do not require frequent battery replacement, but have the disadvantage of short communication distances.

Furthermore, the passive sensing tag is completely dependent on an external energy source to activate the sensing unit, and the sensing amount needs to be reported by using a carrier signal provided by the external. Because such tags have high sensitivity to power consumption, it is difficult to use relatively advanced sensing units and Analog-to-Digital Converter (ADC) devices while securing communication distance.

Electromagnetic RFID sensor

Because the impedance of the RFID tag is affected by the surrounding environment, any change in the object in which the tag is located will result in a change in the RFID echo signal, resulting in a corresponding change in the antenna response. In other words, the antenna itself may become a sensor even if the tag does not have a dedicated sensing unit.

The antenna parameters are typically changed by either a change in the conductivity of the antenna or a portion thereof or a change in the dielectric constant of the surrounding medium or a portion thereof. In the first case the sensor is classified as a resistive sensor, and in the second case the sensor may be classified as a capacitive/inductive sensor. It is worth noting that the sensing results of these two cases are finally reflected in the response to the radio frequency electromagnetic wave, and therefore these sensors are called electromagnetic sensors.

Referring to fig. 1g, the left side of fig. 1g is a schematic diagram of an electronic RFID sensor, and the right side of fig. 1g is a schematic diagram of an electromagnetic RFID sensor.

For a resistive electromagnetic sensor, the sensing result will be reflected in the magnitude of the reflection coefficient, while a capacitive/inductive electromagnetic sensor will be reflected in the frequency offset of the reflected electromagnetic wave.

However, it is noted that the electromagnetic RFID sensor essentially feeds back the sensing amount by changing the reflected electromagnetic wave, and when the tag needs to perform both communication and sensing functions (the communication function needs to be performed by a chip, i.e. an RFID tag with a chip), the communication function may be damaged due to the change of the electromagnetic wave caused by the completion of the sensing function. There are two situations:

(1) For tags that change the antenna conductivity/permittivity due to environmental factors, the environment changes parameters of the antenna itself, causing the antenna to "detune" (Detuned) with respect to the incoming signal, reducing the reflected signal energy that the tag can use for communication, at which point the self-tuning chip can change the total impedance of the antenna by adding additional tunable load impedance, as shown in fig. 1h, keeping "tuned" (Tuned). When the external environment is changed, the self-tuning chip is tuned, the tuned parameters are required to be informed to the receiving end for correctly obtaining the sensing result. Such tags are known as "self-tuning tags".

(2) When the tag is attached to other objects for sensing, the other objects also reflect electromagnetic waves, clutter signals are generated, and the signal quality for communication is reduced. At this time, the tag may be allowed to communicate by reflecting a signal on a frequency multiplication, such as a frequency doubling, of the incident electromagnetic wave. This is because objects in a typical environment have no nonlinear properties that can cause harmonics. Such tags are referred to as "harmonic tags".

The sensing amount acquisition method and the reporting method provided by the embodiment of the application are described in detail through some embodiments and application scenes thereof by combining the attached drawings.

Referring to fig. 2, an embodiment of the present application provides a sensing amount acquisition method, including:

Step 201, a first node transmits first information;

step 202, a first node obtains a perception amount carried in a first signal sent by a first communication device;

Wherein:

the first node is network side equipment, a terminal or a reader-writer;

The first communication device is an RFID Tag, a passive internet of things (Internet of Things, ioT) device, a semi-passive IoT device, or an active IoT device;

The first signal carries the perceived quantity, that is, the first communication device reports the perceived quantity to the first node through the first signal.

In some embodiments, the categories of the first communication device may include:

(1) The first communication device is a passive device, has no energy storage capacitor/battery, is powered by an RF signal (the received RF signal is a power signal of a rectifier), has no carrier generating capability, and has the lowest power consumption;

(2) The first communication device is a semi-passive device having a storage capacitor/battery powered by non-RF signals, optionally having a PA/LNA or other active device, having no carrier generation capability, and consuming less power;

(3) The first communication device is an active device with a storage capacitor/battery powered by a non-RF signal with carrier generation capability and maximum power consumption.

It will be appreciated that the first communication device may be a BSC device and the corresponding first signal may be a "backscatter signal", for example in the case where the first communication device is a passive device or an active device, whereas for the case where the first communication device is an active device, the first signal transmitted by the first communication device is not necessarily a "backscatter signal" but an autonomously generated signal, since the active device may autonomously generate a carrier.

The first signal is sent according to a first configuration, where the first configuration is associated with a sensing amount reporting manner or a sensing amount reporting parameter of the first communication device, and the first configuration is preconfigured, that is, the first communication device is preconfigured, or the first information carries the first configuration, that is, the first configuration may be indicated by the first information, or a part of the first configuration is carried by the first information, another part of the first configuration is preconfigured, that is, the first information indicates part of information, and the remaining information is in a pre/default configuration. The first information may directly indicate a specific parameter of the first configuration, or may indicate one of preset groups of first configurations (i.e., semi-static configurations).

In one possible implementation, the first information may be at least one of triggering the BSC device to start reporting the perceived volume or entering a stage of reporting the perceived volume, and carrying the first configuration.

In one possible implementation, the first configuration is used to configure one or more of:

(1) The sensing quantity reporting mode comprises electronic sensing or electromagnetic sensing;

The electronic perception means that the equipment transmits the perception amount in a traditional communication mode, carries out source coding on the perception amount and forms a data packet/frame, and then transmits the data packet/frame through steps of coding, modulation and the like;

Electromagnetic sensing means that the device does not need to perform additional operations on the sensing quantity, but directly reflects the sensing quantity in the physical properties of the reflected electromagnetic wave, such as frequency, amplitude, phase, polarization direction, beam direction, signal repetition period and the like;

Optionally, for the same sensing amount, multiple resources may be used to repeat reporting as multiple sensing amounts, so as to improve reporting reliability, especially electromagnetic sensing.

It should be noted that the resource may also be periodic or semi-persistent, such as a periodically occurring time window, the periodic/semi-persistent resource may be preconfigured (e.g., other signaling), activated by the first configuration, or configured and activated in the first configuration.

(3) The method comprises the steps of receiving a sensing quantity report mode, wherein the sensing quantity report mode is a transmission format of the sensing quantity under the condition of electronic sensing, such as a frame format, the quantity/position/serial number of the sensing quantity in a data frame, a coding mode, a code rate, a modulation mode, a waveform, a data type (which sensing quantity is marked) and the like;

For the data types, if multiple perception amounts exist, the category of the perception amount needs to be identified in a specific field in the back scattering signal, or if the perception amount is transmitted together with common communication data, the information needs to be used for identifying whether the information belongs to perception information or communication data;

the coding mode can be FM0 code, miller code, manchester code, convolution code, BCH code, MDS code, reed Muller, reed Solomon code and the like;

The modulation scheme may be OOK, BPSK, QPSK, QAM, ASK, FSK or the like;

the waveforms may be single carrier, multi-carrier (e.g., OFDM, OTFS, DFT-S-OFDM, etc.).

(4) Under the condition that the sensing quantity reporting mode is electromagnetic sensing, whether the sensing quantity and communication data are allowed to be simultaneously sent or not;

If yes, whether to activate self-tuning, harmonic wave transmission and corresponding parameters can be configured;

If not, the difference of the sensing quantity and the sending mode of the communication data can be configured, for example, the duration of the sensing quantity and the duration of the communication data are different and are used for receiving the data types received by the receiving end region;

The technical solution of the present application is described below with reference to specific embodiments, which may be combined with each other:

embodiment one, perceptibility reporting method

The reporting of the capability of the first communication device may be performed during the initial access process initiated by the device to the network, or may occur during the registration process after the connection is established, or during the capability query initiated by the reply network.

Case1 initial Access

The initial access refers to a process of acquiring synchronization information of a network and accessing resources through a RACH random access process under the condition that the first communication device has not established a connection with the network. The first communication device may generally be through a 4-step RACH or a 2-step RACH of an existing LTE/NR depending on the type of Random access channel (Random ACCESS CHANNEL, RACH). As shown in fig. 4a, it can be seen that either Msg1 and Msg3 of the 4-step RACH or MsgA of the 2-step RACH can send information to the network, which can carry capability information, as shown in fig. 4 b.

In addition to LTE/NR, the initial access procedure of the existing RFID protocol, such as the initial access procedure of an electronic tag of ISO 18000-6c type, may be referred to as steps 1-8 of fig. 4 c. The perceptibility can be reported by repetition of 5a or 8 a. In fact, the awareness can be reported in the first few packets sent by the first communication device to the network side (when the network side and the first communication device have not established a stable connection), whatever the initial access procedure of which protocol is referenced.

Case2 device registration after connection establishment

After the connection is established, if the first communication device has not been registered with the network, the first communication device needs to perform a device registration procedure next, and the capability information may also be reported through signaling in the registration procedure, such as a registration request Registration Request, as shown in fig. 4d.

Case3 response network initiated capability query

After the connection is established, if the first communication device does not actively send the capability information, the network may also send a signaling such as UE Capability Enquiry requesting the first communication device to report the capability information, and then the first communication device acknowledges the request, as shown in fig. 4e.

The above-mentioned perception capability information of the first communication device specifically includes at least one of the following:

(1) Supported perceptive reporting forms

(1.1) Electronic perception

(1.2) Electromagnetic perception, and reporting of electromagnetic perception (e.g., representing perceived quantity by physical quantity such as frequency offset or amplitude)

(2) Type and number of supported awareness

(3) Supported perceived accuracy

(4) Supported sensing rate or reporting rate

(5) For electromagnetic sensing, whether simultaneous reporting of sensing amount and communication data is supported or not

(5.1) Whether or not the self-tuning function is provided, and the self-tuning capability is provided, such as the adjustable impedance and the quantity thereof, the adjustable impedance serial number (or corresponding relation), the self-tuning speed/time delay

(5.2) Whether to have harmonic transmission function and the harmonic frequency point (such as x frequency multiplication)

(5.3) Mapping relationship between reported quantity and perceived quantity, such as perceived quantity range corresponding to offset of frequency offset

(6) Supported bandwidth, frequency point, resource definition grid, etc

Note that the above-mentioned signaling names are only examples and not exclusive.

Embodiment two: electronic sensor

Embodiment two describes a sensing amount reporting process of the electronic sensor, which is specifically as follows:

(1) Initializing:

(1.1) the first communication device establishing a connection with the first node through the RACH;

(1.2) the first communication device reporting capability information to the first node;

(2) The first node touches the electronic perception report of the electronic type;

the first node sends first information to the first communication equipment, bears the first configuration, triggers the first communication equipment to report the perceived quantity in an electronic perception mode;

(3) The first communication equipment reports the perceived quantity;

depending on the first configuration, the first communication device transmits the perceived quantity to the first node on the specified resources in a conventional backscatter communication manner, and several frame structures may be employed:

case1, a data frame only reports a designated perception amount, an optional field can be added to indicate whether the data frame carries the perception amount or communication data, and the method is specifically shown in fig. 4f;

Case2, reporting a plurality of appointed perception amounts by a data frame, wherein an optional field can be added to indicate whether the perception amount or communication data is carried by the data frame, and the method is specifically shown in fig. 4g;

Case3, reporting a plurality of perception amounts by one data frame, wherein the quantity and the reporting sequence of the perception amounts are undefined, and indicating which perception amount type each perception amount content belongs to at the moment, and because the perception amount type and the type of communication data are different, no independent indication is needed for which field is the communication data, and particularly, see fig. 4h;

The above Case is merely an example, and other combinations are possible, for example, only reporting one sensing amount but the sensing amount type is unknown, then an indication field of the sensing amount type needs to be accessed on the frame structure of Case1, and for example, the number is known but the sensing amount reporting order is unknown, then no separate number indication field is needed in the frame structure of Case 3.

(4) The first node measures a first back scattering signal to obtain a perception amount;

The first node receives the first backscatter signal, obtains data transmitted by the first communication device according to parameters such as a frame structure, coding, modulation scheme, etc. of the first configuration, and then extracts a corresponding perceived quantity therefrom.

Embodiment III: electromagnetic sensor

Embodiment three illustrates a sensing amount reporting process of an electromagnetic sensor, which specifically includes the following steps:

(1) Initialization (if the first communication device does not support communication functions, this step is omitted)

(2) The first node instructs the first communication device to perform a calibration operation;

(2.1) the first communication device transmitting the backscatter signal at a specified reflection coefficient (which may also be totally reflective, non-reflective);

(2.2) the first node measures the back-scattered signal of the first communication device in the absence of feedback perception, and counteracts the influence of the wireless channel itself when the perception is subsequently extracted;

(3) Triggering electromagnetic sensing reporting of the first communication equipment by the first node;

The first node sends first information to the first communication device, carries the first configuration, triggers the first communication device to report the perceived volume in a configured reporting volume (such as amplitude, frequency offset, etc.), where there may be a number of situations:

Case 1. The first communication device does not have communication function and cannot explicitly indicate to which perceived quantity the transmitted signal belongs, or whether the perceived quantity is communication data (possibly mixed with communication data transmitted by other first communication devices)

Option 1 (resource reservation) the first node may indicate or activate the resource window with different awareness in the first configuration, wherein part of the resources are reserved for sending communication data to other first communication devices with communication function, as shown in fig. 4i

Option 2 (self-implementation) the first node may also distinguish what perceived quantity is the received signal or whether the perceived quantity is communication data, such as:

a. The perceived quantity is not likely to change in a period of time, so long as the first node receives a signal which is repeatedly transmitted in a specific time, the signal can be determined to be the perceived quantity;

b. The first node may also attempt to assume that the received information is communication data, decode with a corresponding demodulation decoding method, and if the CRC check cannot be passed, determine that the signal is a perceived quantity;

c. depending on the implementation of the electromagnetic sensor, different perceived amounts (which may be indicated in the first configuration in particular) may be transmitted with different physical properties of the echo signal, for example reporting the temperature with a frequency offset, reporting the humidity with a signal amplitude, then the first node may also distinguish between the different perceived amounts.

Case2, the first communication equipment has a communication function, but cannot simultaneously send communication data and perception amount;

two options for Case1 apply equally. In addition, since the first communication device has a communication function, it is possible to inform the first node of what the perceived amount is transmitted by the first node (in the case where the first communication device has a plurality of perceived amounts transmitted), and the first communication device ID before transmitting the perceived amount;

case3, the first communication equipment has a communication function and simultaneously transmits communication data and perception amount in a self-tuning mode;

the first communication device reports self-tuning parameters, such as used adjustable impedance values or serial numbers in a contracted impedance list, before sending the first backscatter signal so as to inform a receiving end of counteracting perceived quantity reporting deviation caused by self-tuning;

Case4, the first communication equipment has a communication function and simultaneously transmits communication data and perception amount in a harmonic mode;

The method comprises the steps that a first communication device reports harmonic frequency points or multiples of frequency where communication data are sent before sending a first backscatter signal;

The first node measures a first backscatter signal over a specified resource window, measures a reporting amount, and then obtains a perceived quantity based on the first configuration and parameters reported by the first communication device.

Fourth embodiment electronic and electromagnetic switching

The fourth embodiment considers that the first communication device having both electronic and electromagnetic sensing is a switching problem of two modes.

The first communication device needs to indicate that the device has two kinds of capabilities for sensing reporting modes at the same time, and then, the switching of the two kinds of capabilities can be completed in the following ways:

case1, a first node explicitly indicates a mode of reporting the subsequent perception amount;

Case2, the first node only configures the QoS of the perceived quantity, and the first communication equipment selects a proper reporting mode according to the QoS, for example, when the QoS only needs a fuzzy perceived result (such as a 0/1 binary result), the first communication equipment can select electromagnetic perception;

a. the first communication device may explicitly indicate the reporting mode to the first node after selecting the reporting mode;

b. if the two parties have a mapping mode of appointed QoS and reporting mode, no explicit indication is needed at this time;

c. Or when the first node has a blind detection reporting mode (refer to the embodiment III Case 2), explicit indication is not needed;

the Case3, wherein the first communication equipment autonomously switches a sensing quantity reporting mode according to the self condition, for example, when the electric quantity is insufficient, the first communication equipment can switch to electromagnetic sensing;

a. The first communication device may explicitly indicate the reporting mode to the first node after switching the reporting mode;

b. or when the first node has the capability of blind detection reporting mode (refer to the embodiment three Case 2), no explicit indication is needed.

The above embodiments are all written taking a single base architecture (e.g., a conventional RFID reader scenario and a base station/UE only cellular networking architecture) as an example, the following embodiments complement the additional flow under a multi-base architecture.

Fifth embodiment Multi-base architecture

In the multi-base architecture, the aforementioned functions of the first node may be commonly performed by a plurality of nodes, such as a separate control node (for renumbering each node to avoid confusion, hereinafter referred to as a second node), a first information transmitting node (hereinafter referred to as a third node), an energy/carrier providing node (hereinafter referred to as a fourth node), and a sensing amount measurement/backscatter signal receiving node (a fifth node).

At this time, the additional flow required to be supplemented includes:
