[0137] To better understand the information sending method disclosed in this embodiment, the communication system to which this embodiment applies is first described below.

[0138] Figure 1A is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0139] As shown in Figure 1A, the communication system 100 includes a first terminal 101 and a network device 103.

[0140] In some embodiments, the first terminal 101 is an Ambient Internet of Things (A-IoT) terminal, such as an A-IoT device, A-IoT tag, A-IoT User Equipment (UE), etc., which is an IoT device powered by energy harvesting, providing energy by collecting radio waves, light, motion, heat, or any other suitable power source. Terminal 101 may be battery-free or have limited energy storage capacity (e.g., using capacitors), and may use energy harvested from radio waves or any other form of energy available under specific conditions. Terminal 101 may transmit information based on backscatter communication technology.

[0141] In some embodiments, the first terminal 101 needs to collect radio waves sent by nodes in the network to obtain energy before it can power itself to work. Therefore, before obtaining energy, the IoT device is usually in a "power-off" state, that is, offline.

[0142] In some embodiments, the first terminal 101 can be classified into the following types: Type 1, Type 2a, Type 2b, and Type 2c. Type 1 and Type 2a devices are passive devices, while Type 2b devices are active devices. Type 1 devices operate based on backscatter, exhibiting the lowest complexity and lowest power consumption. Type 2a devices support energy storage and operate based on backscatter; their complexity and power consumption are higher than Type 1 devices, possessing some signal amplification capabilities, but still maintaining relatively low power consumption. Type 2b devices operate based on active transmission, possessing signal amplification capabilities and the ability to actively transmit information. Furthermore, Type 2c devices possess both active information transmission and backscatter capabilities. The aforementioned A-IoT devices can possess energy harvesting capabilities, meaning they can extract energy from the environment to supply normal uplink and downlink transmission. Environmental energy includes natural energy such as solar, wind, and nuclear energy, as well as artificial energy such as electromagnetic waves emitted by artificial devices.

[0143] In some embodiments, network device 103 is an A-IoT network device, such as a node or device that connects the first terminal 101 to a wireless network. It may include at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), wireless backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in 6G communication system, open RAN, cloud RAN, base station in other communication systems, access node in Wi-Fi system, A-IoT reader, A-IoT base station, terminal, intermediate node, and auxiliary node, but is not limited thereto.

[0144] In some embodiments, a topology scenario is also supported as shown in FIG1B, and the communication system 100 further includes a second terminal 102.

[0145] In some embodiments, the second terminal 102 includes, but is not limited to, at least one of the following: a mobile phone, a wearable device, an Internet of Things (IoT) device, a car with communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home. The second terminal 102 can communicate with the first terminal 101 and can act as an intermediate node to send data to the network device 102.

[0146] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0147] In some embodiments, the network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU, which is centrally controlled by the CU. However, this is not the only possibility.

[0148] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0149] The following embodiments of this disclosure can be applied to the communication system 100 shown in Figures 1A and 1B, or to some of the main bodies, but are not limited thereto. The main bodies shown in Figures 1A and 1B are illustrative. The communication system may include all or some of the main bodies in Figures 1A and 1B, or it may include other main bodies besides those in Figures 1A and 1B. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative.

[0151] In this embodiment of the disclosure, the A-IoT device may be battery-free or have limited energy storage capacity (e.g., using capacitors). Optionally, the A-IoT device can communicate without a traditional power source, and / or avoid human intervention in charging or battery replacement. The device itself can use energy harvested from radio waves, or any other form of energy available under specific conditions. A-IoT devices are characterized by low memory, low processing power, low power consumption, small data transmission, and mass deployment. Because A-IoT devices do not require traditional batteries, they can operate under extreme environmental conditions (e.g., high voltage, extremely high / low temperatures, humid environments), are maintenance-free, reduce operating costs, and have a longer lifespan.

[0152] For example, in some embodiments, A-IoT devices can harvest energy from radio waves, which may originate from 5G NR network entities or user equipment. In some embodiments, A-IoT devices can also harvest energy from solar energy, light, motion / vibration, heat, pressure, or any other form of energy.

[0153] Optionally, A-IoT devices that use backscattering for uplink transmission require an energy source (CW node) to provide continuous electromagnetic waves (CW) for reflection during backscattering. The CW is typically of constant amplitude. A CW node can be a standalone node, or it can be a base station or intermediate node (e.g., a UE) communicating with the A-IoT device.

[0154] In some embodiments, the frequency of the electromagnetic waves reflected by the A-IoT device can be exactly the same as the frequency of CW or there can be some offset. The magnitude of the offset is related to the hardware characteristics of the A-IoT device. The offset may be a fixed value, or if the A-IoT device hardware supports it, it may support multiple fixed values, or it may be a value that can be dynamically adjusted.

[0155] In some embodiments, due to the characteristics of A-IoT devices, they can be widely applied in various scenarios where positioning is required, such as at least one of the following scenarios:

[0156] 1. Assisting mobile phone positioning: A-IoT devices exist as location markers in the community. A-IoT devices can store information such as floor location to assist mobile phones in spatial positioning.

[0157] 2. Intelligent driving: Vehicle terminals can obtain information about the surrounding environment through sensing A-IoT devices, supplementing the sensing information that cannot be reached by vision.

[0158] 3. Item search: Wearable devices can be integrated with A-IoT devices, and can be sensed, located, and identified by terminals such as mobile phones;

[0159] 4. Material inventory and global management: Items are attached to A-IoT devices and material information is stored, enabling large-scale inventory and management;

[0160] 5. Product loading / unloading: Items are attached to A-IoT devices and their material information is stored. Robots can load or unload products by matching the A-IoT devices between the shelves and the products.

[0161] In summary, it is necessary to consider the positioning process of A-IoT-based devices in different scenarios.

[0684] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0685] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
