[0108] To better understand the information sending method disclosed in this embodiment, the communication system to which this embodiment applies is first described below.

[0109] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0110] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0111] In some embodiments, 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.

[0112] In some embodiments, terminal 101 needs to collect radio waves transmitted by nodes in the network to obtain energy before it can operate. Therefore, before obtaining energy, the IoT device is usually in a "power-off" state, i.e., offline.

[0113] In some embodiments, terminal 101 can be categorized 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. These 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.

[0114] In some embodiments, network device 102 is an A-IoT network device, such as a node or device that connects 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 evolved Node B (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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​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. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0119] The embodiments disclosed herein 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a 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, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0120] 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.

[0121] 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.

[0122] 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.

[0123] In some embodiments, during A-IoT communication, the A-IoT device receives downlink signals from the reader via envelope detection, while the reader may also receive uplink signals from the A-IoT device via envelope detection. In a Reader-to-Device (R2D) scenario, the reader sends control and data information to the device. In a Device-to-Reader (D2R) scenario, the device sends data information to the reader. The method of carrying the aforementioned control / data information is a crucial issue that must be discussed.
