Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0251] In some cases, IoT devices are often powered by traditional batteries with limited lifespans, negatively impacting the user experience. The expected astronomical growth in the number of IoT network devices, coupled with the massive number 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. By eliminating traditional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications.

[0252] In some implementations, various Low Power Wide Area (LPWA) technologies, such as Machine Type Communication (MTC), Narrow Band Internet of Things (NB-IoT), and Reduced Capability (RedCap), have been developed to meet the growing demands of various vertical sectors. These LPWA technologies offer low cost, low power consumption, and large-scale connectivity, meeting the requirements of many applications. However, many use cases and applications remain unaddressed. First, battery-powered devices are not suitable, such as in extreme environmental conditions (e.g., high voltage, extremely high / low temperatures, and humid environments). Second, maintenance-free devices are required (e.g., devices without traditional batteries requiring replacement). Finally, ultra-low complexity, very small device size / form factor (e.g., mm thickness), and extended lifecycles are required. Ambient-powered IoT devices are promising technologies that can address these unmet needs. Ambient-powered IoT devices are IoT devices powered by energy harvesting, either without batteries or with limited energy storage capabilities (e.g., using capacitors). Energy is collected from radio waves, light, motion, heat, or any other suitable power source.

[0253] 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 BLE, LoRa, 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 at the microwatt level, which is unable to drive these types of nodes to work. 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 "Intelligent Connection of Everything". The methods that can be used include backscatter transmission (Backscatter Communications) technology.

[0254] The first device 104 shown in FIG1A can be any device that performs wireless communication using a backscatter transmission mechanism.

[0255] As shown in Figure 1B, the backscatter transmission mechanism is a wireless communication mechanism that utilizes the principle of radio frequency signal backscattering with extremely low-power modulation and transmission technology. A reader sends a physical layer signal to an ambient IoT device. This physical layer signal can be a pulse signal or other AC signal. In some embodiments, this physical layer signal is used to provide energy for the ambient IoT device to transmit the signal. Therefore, this physical layer signal can be referred to as an excitation signal or trigger signal. For example, since a portion of the excitation signal is reflected when it reaches the ambient IoT device, the ambient IoT device can adjust the matching between the receiving antenna and the impedance according to the intended information to enhance the reflection of the incident excitation signal and modulate the acquired sensor data onto the reflected signal to complete the data transmission. This process is similar to a reflector. Compared to other communication technologies, backscatter transmission does not require complex radio frequency structures, reducing the use of components such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing. Therefore, it can simplify the design of ambient IoT devices and significantly reduce the cost of ambient IoT device nodes. Ambient IoT devices are IoT devices that use environmental energy to operate. This environmental energy can include the aforementioned wireless signal energy, as well as other environmental capabilities such as geothermal energy and / or light energy.

[0256] Here, the device that sends a physical layer signal to the ambient IoT device and triggers the ambient IoT device to return a reflected signal can be called an anchor point of the ambient IoT device reader.

[0257] It is worth noting that an ambient IoT device is a device that uses the backscatter transmission mechanism for wireless communication. In specific implementations, other devices can also use the backscatter transmission mechanism for wireless communication.

[0258] The anchor point or reader of the ambient IoT device may be a network node of a wireless communication network, such as an access network device, a relay node (or intermediate node), or a terminal.

[0259] Backscatter transmission network topologies can include one of the following:

[0260] Topology 1: As shown in Figure 1C, uplink (UL) and downlink (DL) data transmission is carried out directly between ambient IoT devices and access network devices.

[0261] Topology 2: As shown in Figure 1D, DL and UL data transmission occurs indirectly between ambient IoT devices and access network equipment. Intermediate nodes (also called auxiliary nodes) provide forwarding services. These intermediate nodes can include relays, integrated access backhaul (IAB), user equipment (UE), and repeaters (RP).

[0262] Topology 3: As shown in Figure 1E, ambient IoT devices and access network devices 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, integrated access backhaul (IAB) nodes, terminals, and network-controlled repeaters (NCRs).

[0263] Topology 4: As shown in Figure 1F, the ambient IoT device and the UE directly receive and transmit data on the downlink and uplink. The UE is responsible for collecting data and forwarding it to the network.

[0264] As shown in Figure 1G, devices that use the backscatter transmission mechanism for wireless communication can be divided into three types:

[0265] Device A: has no energy storage, cannot independently generate and / or amplify signals, and can only perform backscatter transmission.

[0266] Device B: Has energy storage, cannot generate signals independently, and can only perform backscatter transmission. The use of stored energy can include amplification of the backscattered signal.

[0267] Device C: has energy storage and can independently generate signals, that is, it has active radio frequency (RF) components for transmission.

[0268] In the embodiment of the present disclosure, considering the large number of terminals, and therefore considering the coverage range, the terminal may also be selected as an anchor point or reader for a device that communicates using the backscatter principle.

[0269] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0270] S2101: Send the third information.

[0271] In some embodiments, the first terminal sends third information.

[0272] Exemplarily, the first terminal is a terminal selected from among the plurality of terminals as a reader of the first device. The reader may also be referred to as an anchor point.

[0273] In some embodiments, the first terminal sends third information to the access network device.

[0274] In other embodiments, the first terminal sends third information to the core network device.

[0275] In some embodiments, the first terminal sends the third information to a network device when in a connected state or when entering a connected state. The network device may include an access network device and / or a core network device.

[0276] Figure 2 shows a first terminal sending third information, with two options: Option 1 and Option 2. Option 1 is for the terminal to send the third information to the access network device. Option 2 is for the terminal to send the third information to the core network device.

[0277] In some embodiments, the assisting node (or relay node) sends the third information.

[0278] In some embodiments, the first terminal receives a UE capability query from an access network device and sends UE capability information to the access network device. The UE capability information includes the aforementioned third information.

[0279] In some embodiments, the first terminal sends the third information to the core network device through a network registration request message or a registration update message. For example, the first terminal sends the third information to the AMF through a network registration request message or a registration update message.

[0280] In some embodiments, the first terminal may be any communication terminal that includes a power supply module. For example, the first terminal may be any type of communication terminal that includes a battery. For example, the communication terminal may include, but is not limited to, a mobile phone, a tablet computer, an in-vehicle device, a wearable device, a smart home device, and / or a smart office device.

[0281] In other embodiments, the auxiliary node sends the first signal to the first device; the auxiliary node may be one or more pre-set wireless devices with their own power supply modules, such as road monitoring equipment.

[0282] In some embodiments, the third information is used by the network device to select a reader of the first device. The reader of the first device may send a first signal to the first device and receive first information returned by the first device based on the first signal.

[0283] This reader may also be referred to as an anchor point.

[0284] Exemplarily, the third information may be used by the access network device to select a reader for the first device, or the third information may be used by the core network device to select a reader for the first device.

[0285] As another example, when the third information is transmitted to the second device, the second device may select a reader of the first device. The second device may be a receiving device of the first information read by the reader.

[0286] Exemplarily, the third information indicates at least one of the following:

[0287] whether the first terminal supports acting as a reader;

[0288] Whether the first terminal agrees or desires to act as a reader.

[0289] The reader is used to send a first signal to the first device and receive first information returned by the first device.

[0290] That is, in some instances, the third information may include capability information indicating whether the first terminal supports acting as a reader.

[0291] In some embodiments, the third information may further include: indication information indicating whether the user of the first terminal agrees or expects the first terminal to act as a reader.

[0292] In some cases, the third information of the first terminal can be pre-stored in the core network device through subscription information, etc., so the terminal does not need to report the third information. In other cases, for example, the indication information is pre-stored in the core network device through subscription information, while the capability information needs to be reported by the terminal. In still other embodiments, the first terminal only needs to report either the capability information or the indication information.

[0293] In some embodiments, the third information may further include one of the following:

[0294] Time information indicating the time when the first terminal agrees or expects to act as a reader;

[0295] Spatial information indicating a location area in which the first terminal agrees or expects to act as a reader;

[0296] Status information indicates whether the first terminal agrees or expects to act as a reader. The terminal status may be related to the terminal's load rate, whether the terminal has service data to send, the remaining power of the terminal, and / or the terminal's temperature.

[0297] For example, the time information may indicate that the first terminal may act as a reader when its own traffic volume is generally relatively small.

[0298] For another example, the time information may indicate that the first terminal has free traffic or is in a low-rate area and can act as a reader.

[0299] For another example, the status information may indicate that the terminal itself can act as a reader when it has no service data to send.

[0300] For example, the status information may indicate that the terminal can act as a reader when the remaining power of the terminal itself is greater than a power threshold.

[0301] For another example, the status information may indicate that the terminal can act as a reader when its own temperature is lower than a temperature threshold.

[0302] By sending the third information, the communication interference of the first terminal itself when the first terminal acts as the first device reader is reduced, thereby ensuring the communication quality of the first terminal itself.

[0303] In some embodiments, the first device may be a wireless device that does not have a power supply module, a wireless device whose power supply capability of its power supply module is extremely weak, a wireless device that has a power supply module but the power supply module has lost its power supply capability, or any wireless device that supports backscatter communication.

[0304] In some embodiments, the first device may be any passive device, an ambient energy device, or an ambient IoT device.

[0305] Exemplarily, the first device may be device A, device B and / or device C shown in FIG. 1G .

[0306] The second device can be any endpoint that receives the first information. The endpoint is also the device corresponding to the receiving address of the first information, that is, the second device is the receiving device of the first information.

[0307] The second device may include but is not limited to a server or an application function (AF).

[0308] Exemplarily, the first device is an IoT device, and the second device may be an IoT server.

[0309] In some embodiments, the second device may be any network device located within the trust domain of the mobile communication network.

[0310] In some embodiments, the second device may be any network device located in the trust domain of the mobile communication network. Such a second device may be connected to the mobile communication network through a network open function or the like.

[0311] In some embodiments, the first signal at least triggers the first device to send the first information. That is, in some cases, the first signal can serve as a trigger signal for the first device to send the first information.

[0312] In some embodiments, the first signal is an excitation signal for the first device, and the first signal excites the first device to send the first information.

[0313] In some embodiments, the first signal provides energy for the first device to send the first information. Exemplarily, the first device receives the first signal and sends the first information based on the signal energy of the first signal.

[0314] In some embodiments, the first information may include data and / or signaling. For example, the first information may include pre-configured data on the first device and data and / or signaling written to the first device by a third device. For example, the third device may be various sensors. The pre-configured data herein may be any data written to the first device before the first device is put into use.

[0315] The first information may be carried by the reflected signal shown in FIG. 1B .

[0316] Exemplarily, the preset data of the first device includes but is not limited to one of the following:

[0317] a device identifier of the first device;

[0318] device type information of the first device;

[0319] The identification and / or target information of the target carrying the first device. For example, the target carrying the first device may include an object such as a courier. The pre-set data on the first device may include the identification of the target and / or information about the type of courier, the origin and destination of the courier, and / or security information.

[0320] In some embodiments, although the first device does not have its own power supply or only has a power supply module for temporary energy storage or a power supply module with limited power supply capacity, the first device has storage space and serves as an external storage device for a third device, allowing the third device to write data and / or signaling. In this way, even if the first device does not have pre-configured data, the first information in the first device is dynamically updated.

[0321] Illustratively, the third information includes at least one of the following:

[0322] capability information indicating whether the first terminal and / or the auxiliary node supports the reader as the first device;

[0323] Indication information indicating whether the first terminal and / or the auxiliary node agrees or desires to serve as a reader of the first device.

[0324] In some embodiments, the third information further includes at least one of the following:

[0325] Proposed spatiotemporal information, indicating the time information and / or spatial information that the first terminal and / or the auxiliary node agree or expect to serve as a reader of the first device;

[0326] Bandwidth information indicates radio frequency information used by the first terminal and / or the auxiliary node when acting as a reader.

[0327] Of course, the above is just an example of the third information, and the specific implementation is not limited to the above example.

[0328] In some embodiments, the third information may further include:

[0329] whether the first terminal supports acting as a reader; and / or whether the first terminal agrees or desires to act as a reader;

[0330] The reader is used to send a first signal to the first device and receive first information returned by the first device.

[0331] In some embodiments, the access network device receives the third information and stores the third information.

[0332] In some embodiments, the access network device receives the third information and forwards or transparently transmits the third information to the core network device.

[0333] In some embodiments, the core network device receives the third information from the first terminal based on non-access stratum signaling.

[0334] In some embodiments, the core network device receives the third information from the access network device.

[0335] In some embodiments, the core network device receives the third information from the first terminal based on non-access layer signaling, and then the core network device sends the third information to the access network device.

[0336] The core network device receiving the third information here may include but is not limited to the Access Management Function (AMF) and the like.

[0342] In some embodiments, the fourth information includes the second information. The second information may be used by the network device and / or the terminal to send the first signal to the first device and receive the first information from the first device.

[0343] In some embodiments, the second information may include:

After the first terminal enters a connected state, the first signal is sent to the access network device and / or the core network device and / or the second device in the connected state.

[0461] In some embodiments, the first terminal sends a first signal in a connected state. After receiving the first information, the first terminal maintains the connected state at the current moment and sends the first information to the access network device and / or the core network device according to the second information.

[0462] In some embodiments, the first terminal receives the first information in a non-connected state, and upon detecting a preset event, exits the non-connected state and switches to a connected state.

[0475] The reason or purpose may be indicated by using: a task identifier, a device identifier of the first device, a reason indication, or a specific device identifier when the first terminal performs the task of collecting the first information.

[0476] The carrying of the cause and / or purpose enables the access network device to allocate resources to the first terminal accordingly, for example, to allocate SRB and / or DRB to send the first information to the terminal. Exemplarily, the access network device may, based on the cause or purpose, enable the terminal to enter the state of RRC Signaling only connection. In the RRC connection established in the RRC Signaling only connection state, SRB1 and AS security activation are established and SRB2 and / or DRB are not established; or, in the RRC signaling only connection state, SRB and AS security activation are established and DRB is not established, thereby saving unnecessary resources.

[0477] The SRB can be used for signaling interaction between the first terminal and the access network device. The SRB2 can be used for exchanging NAS messages between the first terminal and the core network device. The DRB can be used for data exchange.

[0478] In some embodiments, after the first terminal enters the connected state, a DRB may also be established, and the first information may be sent to the access network device and / or the core network device via the DRB.

The base station matches the task ID through the ID of the environmental IoT device or part of the ID of the environmental IoT device, and then matches the IP address based on the task ID, or directly matches the IP address, and then forwards the received data to the target IP address. Or:

[0655] Option a: The data reported by the environmental IoT device contains task ID information. The base station matches the GTP tunnel or NGAP signaling connection based on the task ID and forwards the data to the CN through the GTP tunnel or NGAP signaling connection.
