[0100] In some embodiments, in the era of the fifth generation mobile communication technology 5G, various low power wide area (LPWA) technologies have been developed, such as machine type communication (MTC), narrowband Internet of Things (NB-IoT), reduced capability (RedCap), etc., to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption and large-scale connectivity, which can meet the requirements of many applications. However, there are still many use cases and applications that cannot be solved in the following situations. First, devices driven by traditional batteries are not applicable, such as in extreme environmental conditions (such as high voltage, extremely high / low temperature, humid environment). Second, maintenance-free equipment is required (for example, there is no need to replace traditional batteries of the device). Finally, ultra-low complexity, very small device size / form factor (such as mm thickness), longer life cycle, etc. are required.

[0101] In some embodiments, ambient powered IoT is a promising technology that can address the unmet needs described above. An ambient powered IoT device is an IoT device that is powered by energy harvesting, either without a battery or with limited energy storage capabilities (e.g., using capacitors), by harvesting radio waves, light, motion, heat, or any other suitable power source.

[0102] In some embodiments, energy obtained from the environment can drive data transmission and wireless communication of sensing nodes. The current mainstream low-power IoT communication chips (such as Bluetooth Low Energy (BLE), LoRa, and NB-IoT) have a transmit and receive power consumption of tens or even hundreds of milliwatts, while the energy obtained by environmental energy harvesting is only in the microwatt level, which is unable to drive these types of nodes. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens of microwatts or even less than ten microwatts. The current mainstream method uses backscatter communication technology. Backscatter Communications is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things, and is an important means to achieve the "Intelligent Connection of Everything".

[0103] In some embodiments, please refer to FIG1B , backscatter communication is a modulation and transmission technology designed with extremely low power consumption using the principle of backscattering of radio frequency signals. Backscatter communication was first proposed by Stockman. When the radio frequency signal reaches the surface of an object, a portion of it will be reflected. The sending node adjusts the matching between the receiving antenna and the impedance according to the information to be sent, thereby enhancing the reflection of the incident radio frequency signal and modulating the perception data acquired by itself onto the reflected signal to complete the transmission of the data. This process is similar to a reflector. Compared with other communication technologies, backscatter communication does not require a complex radio frequency structure, reduces the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters, and does not require complex baseband processing. Therefore, it can simplify terminal design and significantly reduce the cost of terminal nodes.

[0104] In some embodiments, backscatter communication has been widely used in Radio Frequency Identification (RFID) systems, resulting in numerous large-scale commercial applications. Its operating principle is that a receiver (typically an RFID reader) transmits a radio frequency excitation signal, activating a passive node (typically an RFID tag). The tag then uses backscatter communication to modulate its information onto the radio frequency signal. The reader then receives the reflected signal from the passive tag and demodulates it, achieving information transmission.

[0105] In some embodiments, RFID technology also has numerous drawbacks, such as short coverage distance (the wireless signal experiences double-path fading during round-trip communication, resulting in high path loss and a short effective communication range), single-channel transmission, the need for strict tag alignment, and a lack of power control. RFID technology still has significant room for improvement in communication. Integration with 3GPP communication technologies is needed to improve the wireless communication performance of RFID technology in the passive IoT.

[0106] This new type of IoT device needs to have the characteristics of low memory, low processing power, low power consumption, small data transmission, and massive deployment. Environmental IoT devices can be maintenance-free and have a long service life (for example, more than 10 years).

[0107] These new IoT devices require energy from radio waves transmitted by network nodes to power themselves. Therefore, until they receive energy, they are typically powered off, meaning they are disconnected from the network. To address this, the communication system must support data communication methods with shorter transmission times, lower memory consumption, and more convenient terminal management to expedite data communication.

[0108] In some embodiments, a network topology architecture for wireless communication based on ambient energy devices is implemented based on backscatter technology. For example, the network topology construction may include one of the following:

[0109] Topology 1: See Figure 1C. Downlink (DL) and uplink (UL) data are directly received and transmitted between the ambient power IoT device and the base station.

[0110] Topology 2: As shown in Figure 1D , the ambient IoT and the base station indirectly receive and transmit DL and UL data. Intermediary nodes are present for forwarding. For example, the intermediate nodes can be relays, integrated access backhaul (IAB), user equipment (UE), and / or repeaters.

[0111] Topology 3: Referring to Figure 1E , the ambient IoT and the base station directly transmit or receive data in the DL or UL. Auxiliary nodes are located on the UL or DL, responsible for receiving or transmitting UL or DL ​​data. Examples of auxiliary nodes include relays, IABs, UEs, and / or repeaters.

[0112] Topology 4: See Figure 1F. Downlink and uplink data are directly received and transmitted between the ambient IoT and the UE. The UE collects data and forwards it to the network.

[0113] In some embodiments, referring to FIG. 1G , Ambient IoT devices can be divided into three types:

[0114] Device A: No energy storage, no independent signal generation or amplification, i.e. backscatter transmission;

[0115] Device B: has energy storage but no independent signal generation, i.e. backscatter transmission. Utilization of stored energy may include amplification of the reflected signal.

[0116] Device C: has energy storage and independent signal generation, that is, an active radio frequency (RF) component for transmission.

[0117] In some embodiments, communication between a reader and an RFID tag may include a selection phase and an inventory phase. Functionally, tags can be categorized into three types: tag selection, inventory, and access commands. Inventory commands may include the following: Query, QueryAdjust, QueryRep, ACK, and / or NAK.

[0118] Optionally, after receiving a valid Query command, each tag selected by the selected tag that meets the set criteria generates a random number (similar to rolling a dice); each tag whose random number is zero will generate a response (sending back a temporary password RN16 - a 16-bit random number) and transition to the Reply state; tags that meet other conditions will change certain attributes and flags, thereby exiting the above RFID tag group, which helps reduce duplicate identification. The tag can be an RFID tag.

[0119] Optionally, after receiving a valid QueryAdjust command, each tag generates a new random number (like re-rolling a dice), and the rest is the same as the Query command.

[0120] Optionally, after receiving a valid QueryRep command, the tag only decrements the original random number of each tag in the tag group by one, and the rest is the same as the Query command.

[0121] Optionally, only the unified tag can receive a valid ACK command (using the above-mentioned RN16, or handle, a 16-bit random number temporarily representing the tag identity, which is a security mechanism). After receiving it, the tag sends back the content in the EPC area.

[0122] Optionally, after receiving a valid NAK command, the tag switches to the Arbitrate state in all cases except the Ready state and the Killed state, which remain the same.

[0123] In some embodiments, the Query command can be as shown in Table 1; wherein the "Comman" field indicates the command; the "DR" field indicates the data rate; the "M" field indicates the encoding method; the "TRext" field indicates whether the pilot signal is included in the preamble, for example, "No pilot tone" means there is no pilot signal, and "Use pilot tone" means there is a pilot signal; the "Sel" field, the "Session" field and the "Target" field indicate that the tag is filtered, and the tag will only participate in this frame (this round of inventory) when the "Sel" meets the requirements and the corresponding "Session" flag bit is the corresponding "Target"; the "Q" field is the Q value, and the "Q" field is used to indicate the value of the time slot.

[0124] Table 1

[0125] Optionally, the "Session" parameter in the EPC global Class 1 Generation 2 (EPC C1G2, Gen2 for short) protocol is primarily designed to facilitate tag inventory. Each tag contains four sessions (S0-S3), each with two inventory flags, A and B. These tags are not interoperable between sessions. In other words, a tag can simultaneously have an A tag for S2 and a B tag for S3, allowing different readers to inventory the tag simultaneously. Furthermore, in addition to the A and B tags for S0-S3, RFID tags that support the Gen2 protocol also have a tag, SL (~SL), that is interoperable between sessions; any session can use this tag.

[0126] In some embodiments, the QueryAdjust command may be as shown in Table 2; the "UpDn" field indicates the change of the Q value. The QueryAdjust command is used to adjust the Q value. During this round of recognition, the Q value is adjusted using the QueryAdjust command.

[0127] Table 2

[0128] In some embodiments, the QueryRep command is shown in Table 3. The QueryRep command is used to tell the tag to enter the next time slot. After receiving the QueryRep command, the tag will decrement its time slot counter by 1. When the time slot counter reaches 0, it is the tag's turn to send a response message.

[0129] Table 3

[0130] In some embodiments, the response messages from the three readers to the tag (RT) all return RN16; as shown in Table 4, a 16-bit random number is returned.

[0131] Table 4

[0132] RFID systems that comply with the RFID EPC global Class 1 Generation 2 (EPC C1G2, Gen2) standard operate in the 860-960 MHz frequency band. The EPC C1G2 standard primarily provides a unified method for reading data from RFID tags, writing data to tags, and communicating with tags. The EPC C1G2 protocol is a half-duplex protocol, allowing only one reader or tag to transmit a signal during a transmission. Therefore, both the reader and tag cannot transmit simultaneously.

[0133] Compared to RFID systems, ambient IoT systems must support multi-user coexistence. Therefore, the signaling design must meet the requirements of multi-user coexistence. This means that readers must be able to initiate concurrent communications for the same command. For example, if an inventory command requires one type of user to report to the EPC, the reader can initiate an inventory for another type of user before the inventory is completed.

[0209] In some embodiments, step S2102 includes step S2102A and / or step S2102B.

[0210] Step S2102A: The first device determines a first operation.

[0211] In some embodiments, the first device is configured to determine a first operation for the first type of signaling and / or the second type of signaling.

[0212] In some embodiments, the first device is configured to determine a first operation for third-type signaling and / or fourth-type signaling.

[0213] In some embodiments, the first device determines the signaling belonging to the same polling based on the polling identifier in the signaling.

[0214] Exemplarily, the polling identifiers of signaling in the same polling cycle are the same. For example, if the Query signaling, QueryAdjust signaling, and QueryRep signaling all carry a polling identifier of "00," and the ACK signaling and NAK signaling both carry a polling identifier of "01," then the Query signaling, QueryAdjust signaling, and QueryRep signaling are determined to be signaling in the same polling cycle, and the ACK signaling and NAK signaling are determined to be signaling in another polling cycle.

[0215] In some embodiments, the first device determines different types of signaling belonging to the same polling based on the polling identifier and the first message code in the signaling.

[0216] Exemplarily, different first message codes are used to identify different first message types. For example, when the first message code is "00," it is used to identify Query signaling; when the first message code is "01," it is used to identify QueryAdjust signaling; and so on. If the polling identifiers of two signalings acquired by the first device are both "00," and the first message code of the first of the two signalings is "00" and the first message code of the second signaling is "01," then it is determined that the two signalings are signalings of the same polling cycle, and the first of the two signalings is a Query signaling and the second is a QueryRep signaling.

[0217] In some embodiments, the first device determines different types of signaling belonging to the same polling based on the polling identifier, the second message code, and the message subcode in the signaling.

[0218] Exemplarily, different second message codes are used to identify different second message types; and / or different message subcodes are used to identify first message types in different second message types. For example, when the first message code is "00", it is used to identify the first type of signaling; when the first message code is "01", it is used to identify the second type of signaling; and so on. For example, when the message subcode is "0000", it is used to identify Query signaling in the first type of signaling; when the message subcode is "0001", it is used to identify QueryAdjust signaling in the first type of signaling; when the message subcode is "0010", it is used to identify QueryRep signaling in the first type of signaling; when the message subcode is "0011", it is used to identify ACK signaling in the second type of signaling; when the message subcode is "0100", it is used to identify NAK signaling in the second type of signaling; and so on. The polling identifiers of the two signalings obtained by the first device are both "00", and the second message code of the first signaling of the two signalings is "00" and the message subcode is "0000", and the second message code of the second signaling of the two signalings is "01" and the message subcode is "0100"; then it is determined that the two signalings are signalings of the same polling, and the first signaling of the two signalings is the Query signaling in the first type of signaling and the second signaling is the NAK signaling in the second type of signaling.

[0219] In some embodiments, the first device determines the associated signaling from the first device to the second device and / or the associated signaling from the second device to the first device based on the polling identifier and the direction information in the signaling.

[0220] Exemplarily, different direction information is used to identify different transmission directions. For example, when the direction information is "0", it is used to identify the first direction from the first device to the second device; when the direction information is "1", it is used to identify the second direction from the first device to the second device. The first device obtains five signalings; wherein the polling identifiers of the first to fourth signalings are all "00" and the polling identifier of the fifth signaling is "01", the direction information of the first signaling and the third signaling are all "0", and the direction information of the second signaling, the fourth signaling and the fifth signaling are all "1"; then it is determined that the first signaling, the second signaling, the third signaling and the fourth signaling of the same polling can be associated, and / or, the first signaling and the third signaling of the same polling are associated (the transmission directions of the first signaling and the third signaling are both the first direction from the first device to the second device), and / or, the second signaling and the fourth signaling of the same polling are associated (the transmission directions of the second signaling and the fourth signaling are both the second direction from the second device to the first device).

[0221] In some embodiments, the first device determines different first message type signaling based on a message subcode in the signaling.

[0222] For example, a message subcode of "0111" identifies RN16 signaling; a message subcode of "1000" identifies EPC signaling; and a message subcode type of "1001" identifies signaling reporting perception data. For example, if a first device receives two signaling messages, and the message subcode of the first signaling message is "0111" and the message subcode of the second signaling message is "1000," the first signaling message is determined to be RN16 signaling and the second signaling message is determined to be EPC signaling.

[0223] Step S2102B: The second device determines the first operation.

[0224] In some embodiments, the first device is configured to determine a first operation for the first type of signaling and / or the second type of signaling.

[0225] In some embodiments, the first device is configured to determine a first operation for third-type signaling and / or fourth-type signaling.

[0226] In some embodiments, the second device determines the signaling belonging to the same polling based on the polling identifier in the signaling.

[0227] In some embodiments, the second device determines different types of signaling belonging to the same polling based on the polling identifier and the first message code in the signaling.

[0228] In some embodiments, the second device determines different types of signaling belonging to the same polling based on the polling identifier, the second message code, and the message subcode in the signaling.

[0229] In some embodiments, the second device determines the associated signaling from the first device to the second device and / or the associated signaling from the second device to the first device based on the polling identifier and the direction information in the signaling.

[0353] The above embodiments may be implemented individually or in combination with each other. For optional implementations, please refer to the optional implementations of the steps in FIG. 2 and FIG. 4A , which will not be described in detail here.

[0354] The present disclosure relates to an information processing method, which includes:

[0355] Solution 1: different signaling messages in the same round are identified by a round ID or a transaction ID, and / or different signaling messages from the reader to the tag and / or from the tag to the reader are associated.

[0356] In some embodiments, the signaling message includes at least one of the following fields: signaling version (version), signaling message code (message type / code), interaction identifier (eg, polling identifier), message direction (direction), and CRC.

[0357] Optionally, the signaling version is used to indicate the protocol version number. For example, two bits with an initial value of 00 indicate the first version of the ambient IoT system.

[0358] Optionally, the signaling message code is used to indicate the type of signaling message or the category of the message. For example, each signaling message code represents one of the signaling messages, such as Query signaling, QueryAdjust signaling, QueryRep signaling, ACK signaling, and NAK signaling.

[0359] Optionally, the interaction identifier is used to indicate the identity of the signaling message interaction. For example, if the network initiates an inventory, the Query signaling, QueryAdjust signaling, QueryRep signaling sent by the inventory reader, and RN16 signaling sent by the tag related to this inventory will all carry the interaction identifier. Signaling messages carrying the same interaction identifier indicate that they belong to the same inventory process.

[0360] Optionally, the message direction is used to indicate whether the signaling message is from the ambient IoT (e.g., tag) to the reader, or from the reader to the ambient IoT (e.g., tag). For example, using one bit, "0" indicates a message from the reader to the ambient IoT (e.g., tag); "1" indicates a signaling message from the ambient IoT (tag) to the reader.

[0361] Optionally, the reader can be the first device in the previous embodiment; the tag can be the second device in the previous embodiment; the signaling message is the signaling in the previous embodiment; the signaling version is the version information in the previous embodiment; the signaling message code is the first message code in the previous embodiment; the interaction identifier is the polling identifier in the previous embodiment; and the message direction is the direction information in the previous embodiment.

[0362] Solution 2: define a signaling message according to the type of signaling message, and distinguish the signaling message types and signaling structures of different functions through the type carried in the signaling message.

[0363] In some embodiments, the signaling message includes at least one of the following fields: signaling version (version), signaling message code (message type / code), signaling message subcode (message sub-type / code), interaction identifier (such as polling identifier), message direction and CRC.

[0364] Optionally, the signaling version is used to indicate the protocol version number. For example, two bits with an initial value of 00 indicate the first version of the ambient IoT system.

[0365] Optionally, the signaling message code is used to indicate the type of signaling message or the category of the message. For example, each signaling message code represents one of the signaling messages, such as Query signaling and / or NAK, etc. For another example, each signaling message code represents one type of signaling message.

[0366] For example, the Query signaling, QueryAdjust signaling, and QueryRep signaling in the inventory command may belong to the same signaling message code, while the ACK signaling and NAK signaling may belong to another signaling message code. Optionally, the value of the information element may indicate whether it is NACK or NCK.

[0367] Exemplarily, the response message sent by the tag may belong to the same signaling message code, for example, feedback RN16 (i.e., RN16 signaling), feedback EPC (i.e., EPC signaling), and the signaling of perception data are based on the same signaling message code; or, feedback RN16 and feedback EPC belong to the same signaling message code, while the signaling of perception data belongs to another signaling message code.

[0368] Optionally, a message sub-type / code or structure ID is used to indicate a sub-type message of a signaling message code. Different sub-type messages implement different functions and have corresponding signaling frame structures, that is, the values ​​of the included information elements are different, and the position of each information element in the frame structure is also different.

[0369] Optionally, the interaction identifier is used to indicate the identity of the signaling message interaction. For example, if the network initiates an inventory, the Query signaling, QueryAdjust signaling, QueryRep signaling sent by the inventory reader, and RN16 signaling sent by the tag related to this inventory will all carry the interaction identifier. Signaling messages carrying the same interaction identifier indicate that they belong to the same inventory process.

[0370] Optionally, the message direction is used to indicate whether the signaling message is from the ambient IoT (e.g., tag) to the reader, or from the reader to the ambient IoT (e.g., tag). For example, using one bit, "0" indicates a message from the reader to the ambient IoT (e.g., tag); "1" indicates a signaling message from the ambient IoT (tag) to the reader.

[0371] Optionally, the signaling message code may be the second message code in the previous embodiment; and the signaling message subcode may be the message subcode in the previous embodiment.

[0372] In some embodiments, the fields included in the signaling message may be as shown in Table 5; wherein, "Version" represents the signaling version or version information field, and "Version" is 2 bits; "Direction" represents the message direction or direction information field, and "Direction" is 1 bit; "Message code" represents the signaling message code or the first message code field, and "Message code" is 4 bits; "Subtype" represents the signaling message subcode or message subcode field, and "Subtype" is 3 bits; "Round id" represents the interaction identifier or polling identifier field, and "Round id" is 4 bits; "Others" represents other fields; and "CRC" represents the CRC field.

[0373] Table 5

[0374] In some embodiments, the initial trigger message (e.g., Query signaling) of the Query process may be as shown in Table 6; wherein the "Others" field may include a "DR" field, an "M" field, a "TRext" field, a "Session" field, a "Target" field, and / or a "Q" field. Optionally, the "DR" field indicates the data rate; the "M" field indicates the encoding method; the "TRext" field indicates whether a pilot signal is included in the preamble; the "Sel" field, the "Session" field, and the "Target" field indicate that the tag has been screened. Only when "Sel" meets the requirements and the corresponding "Session" flag bit is the corresponding "Target" will the tag participate in this frame (this round of inventory); the "Q" field is the Q value, and the "Q" field is used to indicate the value of the time slot.

[0375] Table 6

[0376] In some embodiments, in an ambient IOT system, the "Others" section may contain different cell information.

[0377] In some embodiments, the repeated Query (e.g., QueryRep signaling) of the Query process may be as shown in Table 7; the "Others" field may include the "Session" field. Optionally, the "Others" field in the QueryRep signaling is different from the "Others" field in the Query signaling.

[0378] Table 7
