[0060] In order to better understand the technical solution of this application, the following contents are first introduced:

[0061] Backscatter Communication (BSC)

[0062] Backscatter communication refers to the use of radio frequency signals from other devices or the environment by backscatter communication equipment to modulate signals and transmit their own information. Backscatter communication equipment (hereinafter referred to as BSC equipment) can be:

[0063] (1) The BSC device in traditional RFID is generally a tag, which is a passive IoT device.

[0064] (2) Semi-passive tags, which have a certain amplification capability for downlink reception or uplink reflection;

[0065] (3) Active tags can send information to the reader without relying on the reflection of the incident signal;

[0066] See Figure 1a and Figure 1b ,in Figure 1a shows a schematic diagram of a backscatter communication system, Figure 1b Schematic diagram showing the principle of backscatter communication

[0067] A simple implementation method is that when the tag needs to send '1', the tag reflects the incident carrier signal, and when the tag needs to send '0', it does not reflect.

[0068] Backscatter communication equipment controls the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. The reflection coefficient of the signal can be characterized as:

[0069]

[0070] Where Z0 is the antenna characteristic impedance and Z1 is the load impedance. Assume that the incident signal is S in (t), the output signal is Therefore, by properly controlling the reflection coefficient, corresponding amplitude modulation, frequency modulation or phase modulation can be achieved. The typical backscatter communication architecture can be divided into a monostatic system and a bistatic system.

[0071] Single-base system

[0072] Figure 1c The figure shows a single-base backscatter communication system, a typical example of which is a traditional RFID system, which includes a BSC device (such as a tag) and a reader. The reader includes an RF source and a BSC receiver, wherein the RF source is used to generate an RF signal (also called an excitation signal, usually a continuous wave (CW)) to power and provide a carrier to the BSC device. The BSC device modulates and backscatters the CW, and the BSC receiver in the reader receives the backscatter signal and performs signal demodulation. Since the RF source and the BSC receiver are in the same device, such as the reader here, it is called a single-base backscatter communication system. In this system, since the RF signal sent from the BSC device will undergo a double near-far effect caused by the signal attenuation of the round-trip signal, the signal energy attenuation is large, so the single-base system is generally used for short-distance backscatter communication, such as traditional RFID applications.

[0073] Dual-base system

[0074] Different from the single-base system, the RF source and BSC receiving end in the dual-base system are separated. Figure 1d Therefore, the dual-base system avoids the problem of large round-trip signal attenuation. In addition, the performance of the backscatter communication system can be further improved by properly placing the RF source.

[0075] Backscatter communication system in cellular network

[0076] In cellular networks, the backscatter communication system can be specifically divided into the following table 1 and Figure 1d The 8 architectures shown.

[0077] Table 1

[0078]

[0079] In architecture 1, the base station is the RF source, the downlink transmitter of the BSC device (i.e., the control command transmitter), and the uplink receiver of the BSC device (i.e., the BSC receiver). In other words, the base station communicates directly with the BSC device. (Note: This deployment architecture has high requirements on the receiving sensitivity of the base station and BSC equipment, but is simple to deploy).

[0080] In architecture 2, the base station is also an RF source, but there is a relay to relay the uplink from the BSC device to the base station. Of course, the relay can also relay the downlink from the base station to the BSC device, which is not listed here.

[0081] In architecture 3, the UE is used as the RF source and forwards the downlink and uplink of the BSC equipment to the base station.

[0082] Architecture 3-1a: The base station is the RF source and directly transmits downlink data to the BSC device. In the uplink, the BSC device first sends a backscattered signal to the UE, which is then forwarded to the base station by the UE.

[0083] Architecture 3-1b: UE is the RF source, and the base station directly transmits downlink data to the BSC device; in the uplink, the BSC device first sends a backscattered signal to the UE, which is then forwarded to the base station;

[0084] Architecture 3-2a: The base station is the RF source. The base station first sends downlink data to the UE, which then forwards it to the BSC device. In the uplink, the BSC device directly sends backscattered signals to the base station.

[0085] Architecture 3-2b: UE is the RF source. The base station first sends downlink data to the UE, which then forwards it to the BSC. In the uplink, the BSC directly sends backscattered signals to the base station.

[0086] Architecture 3-3a: The base station is the RF source. The base station first sends downlink data to the UE, which is then forwarded to the BSC. In the uplink, the BSC sends a backscattered signal to the UE, which is then forwarded to the base station.

[0087] Architecture 3-3b: UE is the RF source. The base station first sends downlink data to the UE, which is then forwarded to the BSC. In the uplink, the BSC sends a backscattered signal to the UE, which is then forwarded to the base station.

[0088] Types of RFID Sensor Tags

[0089] At present, the classification method of RFID tag sensors can be roughly divided into two categories: chip-equipped and chipless. Electronic sensors that directly integrate sensors into traditional RFID tags are the main representatives of the former, while electromagnetic sensors that rely on the electromagnetic response differences caused by antenna detuning to transmit the sensing quantity are the main representatives of the latter.

[0090] Electronic RFID Sensor

[0091] Figure 1f Demonstrate the difference between electronic and electromagnetic sensors, including Figure 1f On the left is a schematic diagram of an electronic RFID sensor. Figure 1f The right side is a schematic diagram of an electromagnetic RFID sensor. It can be seen that the sensing unit of the former needs to interact with the chip, while the sensing quantity of the latter is directly reflected in the frequency response change of the tag.

[0092] RFID sensors with chips can be further divided into active sensor tags (Active Sensor Tags), battery-assisted sensor tags (Battery Assisted Sensor Tags), and passive sensor tags (Battery-Less / PassiveSensors).

[0093] As the name implies, active sensor tags integrate sensors into active tags. The chip installed on the tag can obtain sensor information from the sensor unit, and then convert it into bit information that can be sent, modulated on the self-generated carrier for transmission. The advantage of this type of tag is that the communication distance is long, but at the same time there are problems such as high power consumption, the need to replace batteries, and high costs.

[0094] The working principle of battery-assisted sensor tags is similar to that of active sensor tags, but the difference is that they cannot generate carrier waves autonomously, but need to rely on external carrier waves. The advantage of this type of tag is that it has low power consumption and does not require frequent battery replacement, but the disadvantage is that the communication distance is short.

[0095] Furthermore, passive sensor tags completely rely on external energy sources to activate the sensor unit, and need to use external carrier signals to report the sensing amount. Because this type of tag is highly sensitive to power consumption, it is actually difficult to use more advanced sensor units and analog-to-digital converters (ADCs) while ensuring the communication distance.

[0096] Electromagnetic RFID Sensor

[0097] Because the impedance of an RFID tag is affected by its surroundings, any change in the object the tag is on will cause a change in the RFID echo signal, resulting in a corresponding change in the antenna response. In other words, even if the tag does not have a dedicated sensing unit, the antenna itself can become a sensor.

[0098] There are usually two reasons why antenna parameters change: the conductivity of the antenna or a part of it changes; or the dielectric constant of the surrounding medium or a part of it changes. In the first case, the sensor is classified as a resistive sensor; in the second case, the sensor can be classified as a capacitive / inductive sensor. It is worth noting that the perception results in both cases are ultimately reflected in the response to radio frequency electromagnetic waves, so these sensors are called electromagnetic sensors.

[0099] See also Figure 1g ,in Figure 1g On the left is a schematic diagram of an electronic RFID sensor. Figure 1g On the right is a schematic diagram of an electromagnetic RFID sensor.

[0100] For resistive electromagnetic sensors, the sensing result will be reflected in the amplitude of the reflection coefficient, while for capacitive / inductive electromagnetic sensors, the sensing result will be reflected in the frequency shift of the reflected electromagnetic wave.

[0101] However, it should be noted that the essence of electromagnetic RFID sensors is to feedback the sensing quantity by changing the reflected electromagnetic waves. When the tag needs to complete both communication and sensing functions at the same time (the communication function needs to rely on the chip to complete, that is, the RFID tag with a chip), the changes in the electromagnetic waves caused by completing the sensing function may damage the communication function. There are two situations:

[0102] (1) For tags whose antenna conductivity / dielectric constant changes due to environmental factors, the environment will change the parameters of the antenna itself, making the antenna "detuned" relative to the incident signal, reducing the reflected signal energy that the tag can use for communication. Figure 1hThe self-tuning chip shown can change the total impedance of the antenna by adding an additional adjustable load impedance to keep it "tuned". When the external environment changes and the self-tuning chip is tuned, the tuning parameters need to be informed to the receiving end to obtain the correct perception results. Such tags are called "self-tuning tags".

[0103] (2) When the tag is attached to other objects for sensing, other objects will also reflect electromagnetic waves, generate clutter signals, and reduce the signal quality used for communication. In this case, the tag can be made to reflect the signal at the double frequency of the incident electromagnetic wave for communication, such as the double frequency. This is because objects in the normal environment do not have nonlinear properties that can cause harmonics. Such tags are called "harmonic tags."

[0104] The following, in combination with the accompanying drawings, describes in detail the perception quantity acquisition method and reporting method provided in the embodiments of the present application through some embodiments and their application scenarios.

[0105] See also Figure 2 , the embodiment of the present application provides a method for obtaining a perception amount, including:

[0106] Step 201: The first node sends first information;

[0107] Step 202: The first node obtains a perception amount, where the perception amount is carried in a first signal sent by a first communication device;

[0108] in:

[0109] The first node is a network-side device, terminal or reader / writer;

[0110] The first communication device is an RFID Tag, a passive Internet of Things (IoT) device, a semi-passive IoT device, or an active IoT device;

[0111] The first signal carries the perception amount, that is, the first communication device reports the perception amount to the first node through the first signal.

[0112] In some embodiments, the category of the first communication device may include:

[0113] (1) The first communication device is a passive device, has no energy storage capacitor / battery, relies on RF signals for power supply (the received RF signal is the power signal of the rectifier), does not have carrier generation capability, and has the lowest power consumption;

[0114] (2) The first communication device is a semi-passive device, has a storage capacitor / battery, relies on non-RF signals for power supply, optionally has a PA / LNA or other active devices, does not have carrier generation capability, and has the second highest power consumption;

[0115] (3) The first communication device is an active device, has an energy storage capacitor / battery, relies on non-RF signals for power supply, has carrier generation capability, and consumes the most power.

[0116] It is understandable that the first communication device may be a BSC device, and the corresponding first signal may be a "backscatter signal", for example, when the first communication device is a passive device or an active device; and when the first communication device is an active device, since the active device can autonomously generate a carrier, the first signal sent by the first communication device is not necessarily a "backscatter signal", but an autonomously generated signal.

[0117] The above-mentioned first signal is sent according to the first configuration, and the first configuration is associated with the perception quantity reporting method or perception quantity reporting parameter of the first communication device. The first configuration is a pre-configuration, that is, the first communication device is pre-configured, or the first configuration is carried in the first information, that is, the first configuration can be indicated by the first information, or a part of the first configuration is carried by the first information, and another part of the first configuration is a pre-configuration, that is, the first information indicates part of the information, and the remaining information is a pre-configuration / default configuration. Among them, the first information can directly indicate the specific parameters of the first configuration, and can also indicate one of the preset multiple groups of first configurations (i.e., semi-static configuration).

[0118] In an embodiment of the present application, the first node sends the first information, the first communication device sends the first signal according to the first configuration, and the first signal carries the perception quantity. The first configuration is associated with the perception quantity reporting method or perception quantity reporting parameter of the first communication device, the first configuration is a pre-configuration, or the first configuration is carried in the first information, or a part of the first configuration is carried by the first information, and the other part of the first configuration is a pre-configuration; in this way, different first configurations are set for different types of first communication devices, so as to realize the design of corresponding schemes for reporting perception information for different types of sensor tags.

[0119] In a possible implementation manner, the first information may function as at least one of the following: triggering the BSC device to start reporting the sensing amount or enter a stage of reporting the sensing amount, and carrying the first configuration.

[0120] In a possible implementation manner, the first configuration is used to configure one or more of the following:

[0121] (1) The sensing quantity reporting method includes: electronic sensing or electromagnetic sensing;

[0122] Electronic sensing means that the device sends the sensed quantity in the traditional communication mode, encodes the sensed quantity into a data packet / frame, and then sends it through steps such as encoding and modulation;

[0123] Electromagnetic sensing means that the device does not need to perform additional operations on the sensed quantity, but directly reflects it in the physical properties of the reflected electromagnetic wave, such as frequency, amplitude, phase, polarization direction, beam direction, signal repetition period, etc.

[0124] Optionally, the same sensed quantity may be treated as multiple sensed quantities and reported repeatedly using multiple resources to improve the reliability of the reporting, especially electromagnetic sensing.

[0125] (2) Resources for sending the first signal; for example:

[0126] (2.1) Definition of a time slot (it can be a fixed length of time; it can also be a non-fixed length of time, such as corresponding to a transmission opportunity);

[0127] (2.2) The length of the time slot;

[0128] (2.3) The interval between adjacent frequency points;

[0129] (2.4) The starting position of the time domain or frequency domain resource;

[0130] (2.5) The total amount of time domain or frequency domain resources;

[0131] (2.6) Total number of time slots;

[0132] (2.7) Total number of frequency points;

[0133] (2.8) time domain or frequency domain resource grid;

[0134] It should be noted that resources can also be periodic or semi-persistent, such as a periodically occurring time window; periodic / semi-persistent resources can be pre-configured (such as other signaling) and activated by the first configuration; they can also be configured and activated in the first configuration.

[0135] (3) When the sensing quantity reporting method is electronic sensing, the transmission format of the sensing quantity; such as frame format, number / position / sequence number of the sensing quantity in the data frame, coding method, bit rate, modulation method, waveform, data type (indicating which type of sensing quantity it is), etc.;

[0136] For the above data types, if there are multiple sensing quantities, it is necessary to identify the category of the sensing quantity in a specific field in the backscatter signal; or, if the sensing quantity is sent together with ordinary communication data, it is necessary to identify whether the information belongs to sensing information or communication data;

[0137] The above encoding method can be FM0 code, Miller code, Manchester code, convolutional code, BCH code, MDS code, ReedMuller, Reed Solomon code, etc.;

[0138] The above modulation method can be OOK, BPSK, QPSK, QAM, ASK, FSK, etc.;

[0139] The above waveform can be single-carrier or multi-carrier (such as OFDM, OTFS, DFT-S-OFDM, etc.).

[0140] (4) When the sensing quantity reporting method is electromagnetic sensing, whether it is allowed to send the sensing quantity and communication data at the same time;

[0141] If yes, you can also configure whether to activate self-tuning, harmonic sending, and the corresponding parameters;

[0142] If not, the difference in the sending modes of the sensing amount and the communication data can also be configured, such as stipulating that the duration of the sensing amount is different from the duration of the communication data, so that the receiving end can distinguish the type of data received; for example, stipulating the type of data that can be sent in different resource windows (such as time windows);

[0143] (5) Priority of perceived quantity;

[0144] (6) Quality of service (QoS) of the perceived quantity, and the mapping relationship between the QoS of the perceived quantity and the reporting method of the perceived quantity;

[0145] The QoS of the perceived amount may include at least one of the following:

[0146] Perception resolution, including at least one of the following: ranging (or delay) resolution, velocity (or Doppler) resolution, angle (azimuth, pitch) resolution, imaging resolution, acceleration (X / Y / Z directions) resolution, angular velocity (around X / Y / Z axes) resolution;

[0200] Optionally, before the first node sends the first information, or after the first communication device receives the first information and before sending the first signal, the first node receives the first capability information from the first communication device.

[0201] Optionally, when the sensing amount reporting method is electromagnetic sensing, the first capability information further includes one or more of the following:

[0202] (1) Whether the first communication device has a self-tuning function;

[0205] (4) harmonic frequencies supported by the first communication device;

[0206] (5) A mapping relationship between the reported amount and the perceived amount of the first communication device; for example, a range of the perceived amount corresponding to the frequency offset.

[0207] In a possible implementation manner, when the sensing amount reporting manner is electromagnetic sensing, optionally, before the first node receives the first signal from the first communication device, the method further includes one or more of the following:

[0208] (1) The first node sends first indication information to the first communication device, where the first indication information is used to instruct the first communication device to perform a calibration operation; that is, to measure the change in the physical property of the wireless channel itself to the echo signal when the first communication device does not feed back the perception amount. At this time, the first communication device does not send the perception amount, and can send a backscattered signal with a specified reflection coefficient (which can also be full reflection or no reflection).

[0209] (2) The first node receives a self-tuning parameter of the first communication device from the first communication device; for example, an adjustable impedance value used, or a sequence number in an agreed impedance list, to inform the receiving end to offset the reported amount deviation caused by the self-tuning;

[0210] (3) The first node receives, from the first communication device, a harmonic frequency point used by the first communication device;

[0211] (4) The first node receives second indication information from the first communication device, where the second indication information is used to indicate whether the first communication device switches the sensing amount reporting mode; for example, switching from electromagnetic sensing to electronic sensing;

[0212] (5) The first node receives a sensed quantity type from the first communication device; for example, indicating that the sensed quantity to be reported is temperature / humidity / pressure, etc.;

[0213] (6) The first node receives a device identification ID of the first communication device from the first communication device, where the ID is used to inform the source of the perception quantity to be sent subsequently.

[0214] In a possible implementation, the first information carries information indicating the first communication device participating in the reporting of the sensed quantity, such as a mask and / or length and / or field for matching ID, Electronic Product Code (EPC), Protocol Control / Extended Protocol Control (PC / XPC) information, content at a specific location in an internal memory, sensor results, etc.; or, by default, all first communication devices within the coverage area are selected.

[0215] It should be noted that the first information can be sent via a broadcast message, so the first node can send the first information to multiple first communication devices at the same time. The first information carries information indicating the first communication devices participating in the perception quantity reporting, and can indicate the first communication devices that need to report the perception quantity. In this way, after receiving the first information, each device can determine whether it needs to report the perception quantity.

[0216] In a possible implementation manner, the first information is carried by one or more of the following:

[0217] (1) Dedicated control commands;

[0218] (2) Radio resource control (RRC) signaling;

[0219] (3) Media access control element (MAC CE);

[0220] (4) Uplink control information (UCI);

[0221] (5) Downlink control information (DCI);

[0222] (6) Sidelink control information (SCI);

[0223] (7) Physical frame preamble.

[0224] In one possible implementation,

[0225] The first node sending the first information includes: the first node sending the first information to the first communication device, or the first node instructing the third node to send the first information to the first communication device;

[0226] or,

[0227] The first node acquires the perception quantity including:

[0228] The first node receives the first signal and obtains the perception amount from the first signal; or, the first node receives the first signal forwarded by the fourth node and obtains the perception amount from the first signal; or, the first node receives the perception amount sent by the fourth node;

[0229] Alternatively, the method further comprises at least one of the following:

[0230] The first node sends a continuous carrier CW to the first communication device;

[0231] The first node sends second information to the second node, where the second information is used to instruct the second node to send a CW to the first communication device;

[0232] The first node sends a CW related configuration, where the CW related configuration is used by the second node to send a CW to the first communication device;

[0233] It is understandable that the function of the first node may be completed by a single node. In this case, the first node directly sends the first information to the first communication device, receives the first signal, and obtains the perception amount from the first signal.

[0234] The function of the first node may also be completed by multiple nodes together. For example, a separate control node instructs other nodes (which may include a first information sending node, a power supply / carrier providing node, and a perception quantity measurement / backscatter signal receiving node, wherein the first information sending node, the power supply / carrier providing node, and the perception quantity measurement / backscatter signal receiving node may be one or more nodes, for example, the power supply / carrier providing node also serves as a perception quantity measurement / backscatter signal receiving node). The solution for implementing the above-mentioned perception quantity acquisition through the assistance of other nodes may include one or more of the following:

[0235] (1) The control node sends a CW to the first communication device;

[0236] (2) The control node sends second information to the energy supply / carrier providing node, where the second information is used to instruct the energy supply / carrier providing node to send a CW to the first communication device;

[0237] (3) The first node sends a CW related configuration, where the CW related configuration is used by the energy supply / carrier providing node to send a CW to the first communication device, that is, the energy supply / carrier providing node listens to the first information to obtain the CW related configuration, and sends the CW to the first communication device;

[0238] (4) The control node instructs the first information sending node to send the first information;

[0239] (5) The control node receives the first signal through the sensing quantity measurement / backscatter signal receiving node;

[0240] (6) the control node performs a first configuration on the sensed quantity measurement / backscattered signal receiving node, and receives a sensed quantity from the sensed quantity measurement / backscattered signal receiving node, where the sensed quantity is obtained by the sensed quantity measurement / backscattered signal receiving node from the first signal according to the first configuration;

[0241] Among them, the control node, the first information sending node, the energy supply / carrier providing node, and the perception quantity measurement / backscatter signal receiving node are network side devices, terminals or readers.

[0242] In this case, the first node may be a control node, and the first node may send the first information by instructing the third node to send the first information to the first communication device, or the first node may receive the first signal forwarded by the fourth node and obtain the perception amount from the first signal; or the first node may receive the perception amount sent by the fourth node (the fourth node receives the first signal from the first communication device and receives the first configuration from the first node, and obtains the perception amount from the first signal according to the first configuration).

[0243] It is understandable that the first node may perform different steps when interacting with different first communication devices. For example, when the first node interacts with the first BSC device, it may send first information to the first BSC device and receive a first signal from the first BSC device; when the first node interacts with the second BSC device, it may instruct the third node to send the first information to the second BSC device and receive the perception amount sent by the fourth node (the fourth node receives the first signal from the second BSC device, receives the first configuration from the first node, and obtains the perception amount from the first signal according to the first configuration).

[0244] See also Figure 3 , the embodiment of the present application provides a method for reporting a perceived amount, including:

[0245] Step 301: The first communication device receives first information;

[0246] Step 302: The first communication device sends a first signal according to a first configuration;

[0250] The first signal carries the perceived quantity;

[0251] The first configuration is associated with a perception quantity reporting method or a perception quantity reporting parameter of the first communication device. The first configuration is a pre-configuration. Alternatively, the first configuration is carried in the first information. Alternatively, a part of the first configuration is carried by the first information, and another part of the first configuration is a pre-configuration.

[0252] It should be noted that the solution on the first communication device side can be understood by referring to the description of the solution on the first node side, and will not be repeated here.

[0279] In a possible implementation manner, when the sensing amount reporting method is electromagnetic sensing, the method further includes one or more of the following:

[0280] The first communication device receives first indication information from the first node, where the first indication information is used to instruct the first communication device to perform a calibration operation;

[0286] In a possible implementation manner, the first information carries information indicating a first communication device participating in reporting the perception amount.

[0287] In a possible implementation manner, the first information is carried by one or more of the following:

[0288] Dedicated control commands;

[0290] MAC CE;

[0291] UCI;

[0292] DCI;

[0293] SCI;

[0294] Physical frame preamble.

[0295] In a possible implementation manner, the first communication device receiving the first information includes: the first communication device receiving the first information from the first node, or the first communication device receiving the first information from the third node;

[0296] or,

[0297] The first communication device sending the first signal according to the first configuration includes: the first communication device sending the first signal to the first node according to the first configuration; or the first communication device sending the first signal to the fourth node according to the first configuration;

[0300] The first communication device receives a CW from the second node;

[0301] Among them, the second node, the third node and the fourth node are network-side devices, terminals or readers.

[0302] The technical solution of the present application is described below in conjunction with specific embodiments, and the following embodiments can be combined with each other:

[0303] Example 1: Sensing capability reporting method

[0304] The capability reporting of the first communication device may be performed during the initial access process initiated by the device to the network; it may also occur during the registration process after the connection is established, or in response to a capability query initiated by the network.

[0305] Case 1: Initial access

[0306] Initial access refers to the process of obtaining network synchronization information and access resources through the RACH random access process when the first communication device has not yet established a connection with the network. Depending on the type of random access channel (RACH), the first communication device can generally use the existing LTE / NR 4-step RACH or 2-step RACH. Figure 4aAs shown, it can be seen that Msg1 and Msg3 of 4-step RACH, or MsgA of 2-step RACH can send information to the network and can carry capability information, such as Figure 4b shown.

[0307] In addition to LTE / NR, the initial access process of the existing RFID protocol can also be referred to, such as the initial access process of the ISO18000-6c model electronic tag, such as Figure 4c The sensing capability can be reported through the reply of 5a or 8a. In fact, no matter which protocol is used for the initial access process, the sensing capability can be reported in the first few data packets sent by the first communication device to the network side (when the network side and the first communication device have not yet established a stable connection).

[0308] Case 2: Device registration after connection is established

[0309] After the connection is established, if the first communication device has not registered with the network, the first communication device needs to perform a device registration process. The capability information can also be reported through signaling during the registration process, such as a registration request. Figure 4d .

[0310] Case 3: Responding to capability queries initiated by the network

[0311] After the connection is established, if the first communication device does not actively send capability information, the network may also send a signaling such as UE Capability Enquiry to request the first communication device to report capability information, and then the first communication device responds to the request, such as Figure 4e .

[0312] The sensing capability information of the first communication device specifically includes at least one of the following:

[0313] (1) Supported perception reporting formats

[0314] (1.1) Electronic perception

[0315] (1.2) Electromagnetic perception, and the reported amount of electromagnetic perception (for example, using physical quantities such as frequency offset or amplitude to represent the perceived amount)

[0316] (2) Supported perception types and quantities

[0317] (3) Supported perception accuracy

[0318] (4) Supported sensor data acquisition rate or reporting rate

[0319] (5) For electromagnetic sensing, does it support simultaneous reporting of sensing quantities and communication data?

[0320] (5.1) Whether it has a self-tuning function and its self-tuning capability: such as adjustable impedance and its quantity, adjustable impedance sequence (or corresponding relationship), self-tuning rate / delay

[0321] (5.2) Whether it has the function of harmonic transmission and the harmonic frequency points supported (such as x times)

[0322] (5.3) The mapping relationship between the reported quantity and the perceived quantity, such as the range of the perceived quantity corresponding to the frequency offset

[0323] (6) Supported bandwidth, frequency, resource definition grid, etc.

[0324] In addition, it should be noted that the above signaling names are only examples and are not unique.

[0325] Embodiment 2: Electronic sensor

[0326] Embodiment 2 describes a sensing quantity reporting process of an electronic sensor, which is as follows:

[0327] (1) Initialization:

[0328] (1.1) The first communication device establishes a connection with the first node via RACH;

[0329] (1.2) The first communication device reports capability information to the first node;

[0330] (2) The first node triggers electronic perception reporting;

[0331] The first node sends first information to the first communication device, carrying the first configuration, triggering the first communication device to subsequently report the sensed amount in an electronic sensing manner;

[0332] (3) The first communication device reports the sensing amount;

[0333] Depending on the first configuration, the first communication device sends the sensing amount to the first node on the designated resource in a conventional backscatter communication manner, and the following frame structures may be used:

[0334] Case 1: A data frame reports only one specified sensed quantity; an optional field can be added to indicate whether the data frame carries sensed quantity or communication data. For details, see Figure 4f ;

[0335] Case 2: A data frame reports multiple specified sensing quantities; an optional field can be added to indicate whether the data frame carries sensing quantities or communication data. For details, see Figure 4g ;

[0336] Case 3: A data frame reports multiple sensed quantities, and the number and order of sensing quantity reporting are undefined; in this case, it is necessary to indicate which sensing quantity type each sensing quantity content belongs to. Since the sensing quantity type and the communication data type are different, it is not necessary to indicate which field is the communication data separately. For details, see Figure 4h ;

[0337] The above situations are only examples, and there may be other combinations. For example, only one perception quantity is reported, but the type of perception quantity is unknown. In this case, an indication field of the perception quantity type needs to be added to the frame structure of Case 1. For another example, the quantity is known, but the order in which the perception quantities are reported is unknown. In this case, a separate quantity indication field is not required in the frame structure of Case 3.

[0338] (4) The first node measures the first backscattered signal to obtain a sensing amount;

[0339] The first node receives the first backscatter signal, obtains the data sent by the first communication device according to the frame structure, coding, modulation scheme and other parameters of the first configuration, and then extracts the corresponding perception amount therefrom.

[0340] Embodiment 3: Electromagnetic sensor

[0341] Example 3 describes a sensing quantity reporting process of an electromagnetic sensor, which is as follows:

[0342] (1) Initialization: (If the first communication device does not support the communication function, this step is ignored)

[0343] (1.1) The first communication device establishes a connection with the first node via RACH;

[0344] (1.2) The first communication device reports capability information to the first node;

[0345] (2) The first node instructs the first communication device to perform a calibration operation;

[0346] (2.1) The first communication device sends a backscattered signal with a specified reflection coefficient (which may also be full reflection or no reflection);

[0347] (2.2) The first node measures the backscattered signal of the first communication device when no perception amount is fed back, so as to offset the influence of the wireless channel itself when subsequently extracting the perception amount;

[0348] (3) The first node triggers the first communication device to electromagnetically sense and report;

[0349] The first node sends the first information to the first communication device, carrying the first configuration, triggering the first communication device to subsequently report the perception amount with the configured reporting amount (such as amplitude, frequency offset, etc.). There may be multiple situations:

[0350] Case 1: The first communication device does not have a communication function and cannot explicitly indicate which type of sensing quantity the transmitted signal belongs to; or whether the sensing quantity is still communication data (which may be mixed with communication data transmitted by other first communication devices)

[0351] Option 1 (resource reservation): The first node may indicate or activate resource windows where different sensing quantities are located in the first configuration, where part of the resources are reserved for other first communication devices with communication functions to send communication data, such as Figure 4i Shown

[0352] Option 2 (self-realization): The first node can also distinguish whether the received signal is a sensor quantity or a sensor quantity or communication data through some judgment conditions, such as:

[0353] a. The perceived quantity is likely to remain unchanged for a period of time. Therefore, as long as the first node receives a signal that is repeatedly sent within a specific period of time, it can be determined that the signal may be the perceived quantity;

[0354] b. The first node may also try to assume that the received information is communication data and decode it using a corresponding demodulation and decoding method. If the CRC check fails, it may also be determined that the signal is a perception quantity;

[0355] c. Depending on the implementation method of the electromagnetic sensor, different physical properties of the echo signal can be used to send different perception quantities (which can be specifically indicated in the first configuration), such as using frequency deviation to report temperature and using signal amplitude to report humidity, so the first node can also distinguish different perception quantities.

[0356] Case 2: The first communication device has the communication function, but cannot send communication data and sensing data at the same time;

[0357] The two options of Case 1 are also applicable. In addition, since the first communication device has a communication function, before sending the perception quantity, the first node can be informed of what the perception quantity to be sent is (for the case where the first communication device has the function of sending multiple perception quantities) and the first communication device ID;

[0358] Case 3: The first communication device has a communication function and simultaneously sends communication data and sensing quantity in a self-tuning manner;

[0359] The first communication device reports a self-tuning parameter, such as an adjustable impedance value used, or a sequence number in an agreed impedance list before sending the first backscatter signal, to inform the receiving end to offset the perception amount reporting deviation caused by the self-tuning;

[0360] Case 4: The first communication device has a communication function and simultaneously sends communication data and sensing quantity in a harmonic manner;

[0361] The first communication device reports the harmonic frequency point at which the communication data is sent, or the multiple of the frequency, before sending the first backscatter signal;

[0362] (4) The first node measures the first backscattered signal to obtain a sensing amount;

[0363] The first node measures the first backscatter signal in the designated resource window, measures the reporting amount, and then obtains the perception amount according to the first configuration and the parameters reported by the first communication device.

[0364] Embodiment 4: Switching between electronic and electromagnetic

[0365] Embodiment 4 Considering a first communication device having both electronic and electromagnetic sensing, there is a problem of switching between two modes.

[0366] The capability information reported by the first communication device first needs to indicate that the device has the capability of two sensing reporting modes at the same time. Next, the switching between the two modes can be completed in the following ways:

[0367] Case 1: The first node explicitly indicates the method of reporting subsequent perception quantities;

[0368] Case 2: The first node only configures the QoS of the sensed amount, and the first communication device selects an appropriate reporting method according to the QoS. For example, when the QoS only requires fuzzy sensing results (such as 0 / 1 binary results), the first communication device can select electromagnetic sensing;

[0369] a. After selecting the reporting method, the first communication device may explicitly indicate the reporting method to the first node;

[0370] b. If both parties have agreed on the mapping between QoS and reporting methods, no explicit indication is required;

[0371] c. Alternatively, when the first node is capable of blind detection reporting (refer to Example 3 Case 2), there is no need for explicit indication;

[0372] Case 3: The first communication device autonomously switches the sensing quantity reporting method according to its own situation. For example, when the battery is low, it can switch to electromagnetic sensing.

[0373] a. After switching the reporting mode, the first communication device may explicitly indicate the reporting mode to the first node;

[0374] b. Alternatively, when the first node is capable of blind detection reporting (refer to Example 3 Case 2), no explicit indication is required.
