For another example, if the description object is a "level", the ordinal number before the "level" in the "first level" and the "second level" does not limit the priority between the "levels". For another example, the number of description objects is not limited by the ordinal number and can be one or more. Taking "first device" as an example, the number of "devices" can be one or more. In addition, the objects modified by different prefixes can be the same or different. For example, if the description object is "device", then the "first device" and the "second device" can be the same device or different devices, and their types can be the same or different; for another example, if the description object is "information", then the "first information" and the "second information" can be the same information or different information, and their contents can be the same or different.

[0217] As shown in FIG1 a , a communication system 100 includes a terminal 101 , a network device 102 and an environmental IoT device 103 .

[0218] In some embodiments, the network device includes an access network device and a core network device.

The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0226] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0227] In some cases, IoT devices in IoT networks are often powered by traditional batteries with limited lifespans, negatively impacting user experience. The astronomical growth of IoT networks, coupled with the proliferation of IoT devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of traditional batteries are discarded each year, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in extreme environmental conditions. Battery-free IoT communications have been proposed to improve network performance and sustainability, expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. Eliminating traditional batteries significantly reduces device size and cost, paving the way for a variety of new applications.

[0228] 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.

[0229] 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.

[0230] In some embodiments, energy harvested from the environment can drive data transmission and wireless communications among sensor nodes. Current mainstream low-power IoT communication chips consume tens or even hundreds of milliwatts of power for both transmission and reception, while ambient energy harvesting only captures microwatts, making them inadequate for powering these nodes. Therefore, new wireless communication technologies are needed to reduce communication energy consumption to tens or even below ten microwatts. Backscatter communications, currently a mainstream approach, is a key technology for building a green, energy-efficient, and flexibly deployable future IoT, and a crucial means of achieving the "Intelligent Connection of Everything."

[0231] In some embodiments, please refer to Figure 1b. Backscatter communication is a modulation and transmission technology designed with extremely low power consumption, which utilizes 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 part 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 that of 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.

[0232] 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.

[0233] In some embodiments, RFID technology also has numerous drawbacks, such as limited coverage (the wireless signal experiences double-path fading during the round-trip communication process, 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.

[0234] The expected new type of IoT devices 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).

[0235] 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.

[0236] In some embodiments, see FIG1c, which shows a network architecture for wireless communication based on backscatter technology to achieve communication between ambient energy devices.

[0237] Architecture 1: Direct downlink (DL) and uplink (UL) data reception and transmission between ambient power IoT devices and base stations.

[0238] Architecture 2: DL and UL data reception and transmission are performed indirectly between the ambient IoT and the base station; intermediate nodes exist in the middle to forward data. For example, the intermediate nodes can be relays, integrated access backhaul (IAB), UEs, and repeaters.

[0239] Architecture 3: 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 sending UL or DL ​​data. Examples of auxiliary nodes include relays, IABs, UEs, and repeaters.

[0240] Architecture 4: Direct DL and UL data reception and transmission between ambient IoT and UE; UE is responsible for collecting data and forwarding it to the network.

[0241] In some embodiments, referring to FIG1d , Ambient IoT devices can be divided into three types:

[0242] Device A: No energy storage, no independent signal generation / amplification, i.e. backscatter transmission;

[0243] Device B: has energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy may include amplification of the reflected signal.

[0244] Device C: has energy storage and independent signal generation, i.e., active RF components for transmission.

[0245] In some embodiments, in order to support data transmission of A-IoT devices, the network needs to support the following functions: A device in the network can support one or more functions.

[0246] In some embodiments, the function as an energy source (ES) is only used for device type B and type C.

[0247] In some embodiments, the downlink transmission (DT) function sends indication information to the A-IoT device, thereby triggering uplink transmission of the A-IoT device.

[0248] In some embodiments, the continuous wave (CW) excitation function is used only by devices A and B. A-IoT devices achieve uplink transmission by backscattering CW. CW is actually a type of ES, and A-IoT devices can receive CW and store energy.

[0249] In some embodiments, the uplink receiving (UR) function receives uplink information backscattered by the A-IoT device, or receives uplink information actively transmitted by the A-IoT device.

[0250] In some embodiments, the device performing the above-mentioned ES, DT, CW, or UR functions may be a UE, a repeater, a relay, or a base station. A device may support only one of the above-mentioned functions. Alternatively, a device may support multiple of the above-mentioned functions simultaneously. Alternatively, a device may support all of the above-mentioned functions simultaneously.

[0251] In some embodiments, in an RFID communication system, commands are divided into three categories based on their functionality: Select, Inventory, and Access. There are five Inventory commands: Query, QueryAdjust, QueryRep, ACK, and NAK, all of which are mandatory.

[0252] In some embodiments, after a tag receives a valid Query command, each tag selected by the set criteria generates a random number (similar to rolling a dice), and each tag whose random number is zero will generate a response (send back a temporary password RN16 - a 16-bit random number) and transfer to the Reply state; tags that meet other conditions will change certain attributes and flags, thereby exiting the above tag group, which helps to reduce duplicate identification.

[0253] In some embodiments, 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 Query.

[0254] In some embodiments, 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 Query.

[0255] In some embodiments, only a single tag can receive a valid ACK command (using the aforementioned RN16, or handle—a 16-bit random number temporarily representing the tag's identity, as a security mechanism!). Upon receipt, it then sends back the contents of the EPC area—the most basic function of the EPC protocol.

[0256] In some embodiments, after receiving a valid NAK command, the tag switches to the Arbitrate state except for the Ready or Killed states where the tag remains in the original state.

[0257] In some embodiments, two topology scenarios are supported: one is a direct connection between an ambient IoT base station (or reader) and an ambient IoT device (or tag); the other is communication between an ambient IoT device and a user end user (UE), with the UE acting as an intermediate node and sending data to the network.

[0258] In some embodiments, please refer to 1c again. The spectrum resources that can be used for Ambient IOT communication (i.e., communication between ambient IOT device and base station (architecture / topology 1) and UE (architecture / topology 2)) can be in the form of in-band, guard-band or stand alone. Among them, in-band uses normal NR communication (such as DL / UL communication between base station and other UE (topology 1) and DL / UL communication between UE and base station (topology 2)) DL and / or UL spectrum resources. Guard-band uses the spectrum resources of the protection band of normal NR communication DL and / or UL spectrum, and stand alone uses spectrum resources unrelated to NR communication.

[0259] In some embodiments, in topology 2, if an RRC_CONNECTED UE acts as a reader and receives data reported by an ambient IoT device, triggering the UE to send RRC signaling to report the data to the network, this will result in a large amount of air interface RRC signaling, wasting air interface resources and increasing UE power consumption. If the UE collects a certain amount of data before reporting, there may be delays in ambient IoT signaling or service delivery.

[0260] FIG2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0261] Step S2101: The network device sends information to the terminal.

[0262] In some embodiments, the terminal receives information sent by the network device.

[0264] In some embodiments, the reader may be a radio frequency identification (RFID) reader. It should be noted that a reader may also be referred to as a receiver. In the embodiments of the present disclosure, "reader" and "receiver" are interchangeable and are not limited here.

[0265] In some embodiments, before the UE becomes a reader, the network device configures the UE to become a reader through RRC dedicated signaling, and the configuration information includes wireless resource configuration information of the UE as a reader.

[0266] In some embodiments, the wireless resource configuration information includes: time domain and / or frequency domain resource information, and / or functional information of the time domain and / or frequency domain resources, for example, whether the time domain and / or frequency domain are used for power signal transmission, CW transmission, DL signaling transmission, and / or BS reception.

[0267] In some embodiments, after the UE becomes a reader, the protocol stack between the UE and the ambient IOT device (corresponding to the ambient IoT device) includes a physical layer PHY and a logical control layer MAC-IOT or IOT layer. The PHY layer is used for physical layer data transmission, and the MAC-IOT or IOT layer is used to transmit the communication process between the reader to the device R2D and the device to the reader D2R of the ambient IoT system. R2D can also be referred to as reader to ambient IoT device, and D2R can also be referred to as ambient IoT device to reader, which is not limited here.

[0268] In some embodiments, the communication protocol stack between the UE and the upstream node gNB is the physical layer PHY and the multimedia access control layer PHY MAC.

[0269] In some embodiments, after becoming a reader, the UE prepares to receive task information about the ambient IoT system from the network. For example, it receives a paging message, which is used to select at least one device to participate in the task. The UE sends this message to the device, which, if permitted to do so, sends uplink signaling, such as RN16 indication signaling.

[0270] In some embodiments, based on the first protocol layer protocol, the network device performs information transmission between the terminal and the network device.

[0271] In some embodiments, the first protocol layer protocol includes a medium access control MAC layer protocol and / or a radio resource control RRC layer protocol.

[0272] In some embodiments, the MAC layer protocol includes: a first MAC layer protocol used for communication between the terminal and the network device.

[0273] In some embodiments, the RRC layer protocol includes: a first RRC layer protocol used for communication between the terminal and the network device.

[0274] In some embodiments, based on the first protocol layer protocol, the network device transmits information between the terminal and the network device through signaling.

[0275] In some embodiments, the signaling includes a first information field and a second information field.

[0276] In some embodiments, the first information field is used to indicate at least one of the following: a task identifier; an inventory identifier; and a device identifier.

[0277] In some embodiments, the second information field is used to indicate an air interface command for communication between the environmental IoT device and the terminal.

[0279] In some embodiments, the first downlink signaling includes second information.

[0280] In some embodiments, the second information is used to indicate a reader-to-ambient IoT device command and / or an identification of the ambient IoT device.

[0281] In some embodiments, the first protocol layer protocol is associated with the first protocol layer.

[0282] Exemplarily, when the first protocol layer protocol is a MAC layer protocol, the first protocol layer is a MAC layer; when the first protocol layer protocol is an RRC layer protocol, the first protocol layer is an RRC layer.

[0285] In some embodiments, the MAC layer is a Media Access Control (MAC) layer between the terminal and the network device.

[0286] In some embodiments, the RRC layer is a radio resource control (RRC) layer between the terminal and the network device.

[0287] In some embodiments, the network device sends information to the terminal at a first protocol layer.

[0288] In some embodiments, the network device sends the second information to the terminal at the first protocol layer.

[0289] In some embodiments, information between the network device and the terminal is transmitted via signaling.

[0290] In some embodiments, the network device sends the second information to the terminal via a first downlink signaling.

[0291] In some embodiments, the second information is information associated with environmental Internet of Things communications. In some embodiments, the signaling may be downlink signaling, such as downlink MAC CE, downlink RRC signaling.

[0292] In some embodiments, signaling (eg, MAC CE signaling) may be identified by a logical channel identifier (LCID).

[0293] Please refer to Figure 2c, which shows the downlink MAC CE.

[0294] In some embodiments, the signaling (eg, MAC CE signaling) may include at least one of a task ID, an inventory round ID, and a device ID of the triggered task, or may not include any of the above identifiers.

[0295] In some embodiments, signaling (eg, MAC CE signaling) includes a container that includes DL signaling.

[0296] In some embodiments, the DL signaling container includes air interface signaling between a device and a reader.

[0297] Step S2102: The terminal sends information to the environmental IoT device.

[0298] In some embodiments, the ambient IoT device receives information sent by the terminal.

[0299] In some embodiments, the information is information associated with ambient IoT communications.

[0300] In some embodiments, the terminal sends the second information to the ambient IoT device.

[0301] In some embodiments, the second information is information associated with ambient IoT communications.

[0302] In some embodiments, based on the first protocol layer protocol, the terminal executes the transmission of information between the environment IoT device and the terminal.

[0303] In some embodiments, the MAC layer protocol includes: a second MAC layer protocol used for the terminal to communicate with the environmental IoT device.

[0304] In some embodiments, the RRC layer protocol includes: a second RRC layer protocol for communication between the terminal and the environmental IoT device.

[0305] In some embodiments, the first protocol layer protocol is associated with the first protocol layer.

[0306] Exemplarily, when the first protocol layer protocol is a MAC layer protocol, the first protocol layer is a MAC layer; when the first protocol layer protocol is an RRC layer protocol, the first protocol layer is an RRC layer.

[0307] In some embodiments, referring to FIG. 2d , FIG. 2e or FIG. 2f , the first protocol layer is a media access control MAC layer and / or a radio resource control RRC layer.

[0308] In some embodiments, the MAC layer includes an IoT media access control IOT-MAC layer between the terminal and the ambient IoT device.

[0309] In some embodiments, the RRC layer is an IoT radio resource control (IOT-RRC) layer between the terminal and the environmental IoT device. In some embodiments, information between the environmental IoT device and the network device is transmitted via signaling based on a first protocol layer protocol.

[0310] In some embodiments, the signaling includes a first information field and a second information field.

[0311] In some embodiments, the first information field is used to indicate at least one of the following: a task identifier; an inventory identifier; and a device identifier.

[0312] In some embodiments, the second information field is used to indicate an air interface command for communication between the environmental IoT device and the terminal.

[0313] In some embodiments, the second downlink signaling is sent to the environmental Internet of Things device.

[0314] In some embodiments, the second downlink signaling includes the second information.

[0315] In some embodiments, the second information is used to indicate a reader-to-ambient IoT device command and / or an identification of the ambient IoT device.

[0316] In the present disclosure, the reader-to-environment IoT device command may be an R2D command.

[0317] In some embodiments, based on the second information, it is determined whether to perform conversion processing on the identifier indicated by the second information.

[0318] In some embodiments, based on the type of the identifier indicated by the second information, it is determined whether to perform conversion processing on the identifier indicated by the second information.

[0319] In some embodiments, it is determined that the identifier indicated by the second information is an identifier of a first type, and the identifier of the first type is converted into an identifier of a second type based on a first mapping relationship.

[0320] In some embodiments, it is determined that the identifier indicated by the second information is an identifier of the second type, and no conversion processing is performed on the identifier indicated by the second information.

[0321] In some embodiments, the first type of identifier is an identifier assigned by a higher layer, and the second type of identifier is a device identifier for interface communication between the environmental IoT device and the terminal; the first mapping relationship is used to indicate the correspondence between the first type of identifier and the second type of identifier.

[0322] In some embodiments, the first type of identification includes at least one of the following:

[0323] EPC logo;

[0324] Label identification.

[0325] The second type of identifier is RN16.

[0326] Illustratively, for UE-to-device signaling, that is, the UE receives a command (eg, second information) from an upstream source, the UE extracts a DL command (corresponding to a downlink air interface command) from the received MAC CE, and then sends the command to the device.

[0327] For example, if the device ID in the MAC CE is an EPC or tag ID, that is, an ID assigned by a higher layer (corresponding to the first type of identifier), the UE needs to map the ID to an air interface (the interface between the device and the reader) tag identifier, such as RN16 (corresponding to the second type of identifier), and send the RN16 and the DL command together to the device. The RN16 is used to identify that the command is sent to the tag corresponding to the RN16. In this case, the gNB or UE needs to maintain the mapping relationship between the tag EPC and the RN16.

[0328] For example, a DL command is directly sent to the device, and the command includes device ID information, for example, the device ID is an identifier assigned by a higher layer such as EPC or tag ID (corresponding to the first type of identifier).

[0329] For example, if the device ID is RN16, that is, a temporary identifier assigned by the reader (corresponding to the second type of identifier), the UE sends the device ID and the DL command to the device. It should be noted that at this time, the UE needs to send the EPC and RN16 to the CN or IOT server at the same time during the initial access process, and the network side can indicate that RN16 is in the DL MAC CE when issuing the command. Alternatively, the IOT server can directly include the identifier in the DL command. The UE can directly forward the DL command.

[0330] In some embodiments, the signaling may be downlink signaling, for example, downlink MAC CE, downlink RRC signaling.

[0331] In some embodiments, signaling (eg, MAC CE signaling) may be identified by a logical channel identifier (LCID).

[0332] Please refer to Figure 2c again, which shows the downlink MAC CE.

[0333] In some embodiments, the signaling (eg, MAC CE signaling) may include at least one of a task ID, an inventory round ID, and a device ID of the triggered task, or may include none of the above identifiers.

[0334] In some embodiments, signaling (eg, MAC CE signaling) includes a container that includes DL signaling.

[0335] In some embodiments, the DL signaling container includes air interface signaling between a device and a reader.

[0336] Step S2103: The environmental Internet of Things device sends information to the terminal.

[0337] In some embodiments, the terminal receives information sent by the environmental IoT device.

[0338] In some embodiments, the information is information associated with ambient IoT communications.

[0379] In some embodiments, the first information field is used to indicate at least one of the following: a task identifier; an inventory identifier; and a device identifier.

[0380] In some embodiments, the second information field is used to indicate an air interface command for communication between the environmental IoT device and the terminal.

[0381] In some embodiments, based on the first information, it is determined whether to send a second uplink signaling to the network device.

[0382] In some embodiments, the second uplink signaling includes the first information.

[0383] In some embodiments, whether to send the second uplink signaling to the network device is determined based on the type of the command from the environmental Internet of Things device to the reader indicated by the first information.

[0384] Here, the ambient IoT device-to-reader command may be a D2R command.

[0385] In some embodiments, it is determined that the type of the command from the environmental IoT device to the reader is a first type of command, and the second uplink signaling is not sent to the network device.

[0386] In some embodiments, it is determined that the type of the command from the environmental Internet of Things device to the reader is a second type of command, and the second uplink signaling is sent to the network device.

[0390] In some embodiments, it is determined that the first information indicates that the handshake operation between the environmental Internet of Things device and the network device is not completed, and the second uplink signaling is not sent to the network device.

[0391] In some embodiments, it is determined that the first information indicates that a handshake operation between the environmental IoT device and the network device is completed, and the second uplink signaling is sent to the network device.

[0392] In some embodiments, the first protocol layer protocol is associated with the first protocol layer.

[0393] Exemplarily, when the first protocol layer protocol is a MAC layer protocol, the first protocol layer is a MAC layer; when the first protocol layer protocol is an RRC layer protocol, the first protocol layer is an RRC layer.

[0396] In some embodiments, the RRC layer is a radio resource control (RRC) layer between the terminal and the network device.

[0397] Exemplarily, for signaling from a device (corresponding to an environmental IoT device) to a UE, the UE determines whether to forward the signaling to an upstream node through the MAC CE above over the air interface based on the type of command or message (corresponding to the third information), or the device status or communication status (corresponding to the third information).

[0398] For example, for commands related to the inventory process, such as uplink signaling such as RN16 reporting, device temporary identity allocation confirmation and / or EPC reporting, D2R signaling (device to reader signaling or commands) does not need to be forwarded to the upstream node (network device), and the command terminates at the reader (that is, UE).

[0399] For example, a command of the access command type, for example, an operation on a device, such as a read and write command, needs to be forwarded to an upstream node.

[0400] Exemplarily, the device state or the device communication state (corresponding communication state) may be a handshake completion state.

[0401] For example, commands before the handshake between the device and reader is completed do not need to be forwarded to the upstream node, but commands after the handshake is completed need to be forwarded to the upstream node.

[0402] For example, the UE needs to store the correspondence between the EPC and RN16 so as to fill in the EPC field in the UL MAC CE when forwarding data. That is, the UE maps the EPC according to the correspondence between RN16 and EPC.

[0403] In some embodiments, the communication state includes a state in which the ambient IoT device communicates based on ambient energy.

[0404] In some embodiments, the signaling may be uplink signaling, for example, uplink MAC CE, uplink RRC signaling.

[0406] Please refer to Figure 2g again, which shows the uplink MAC CE.

[0407] In some embodiments, the signaling (eg, MAC CE signaling) may include at least one of a task ID, an inventory round ID, and a device ID of the triggered task, or may include none of the above identifiers.
