[0093] In order to better understand a power determination method disclosed in an embodiment of the present disclosure, the communication system to which the embodiment of the present disclosure is applicable is first described below.

[0094] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0095] As shown in FIG1A , a communication system 100 includes a first terminal 101 , a second terminal 102 , and a network device 103 .

[0096] In some embodiments, the first terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, 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 at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0097] In some embodiments, the second terminal 102 is, for example, an Ambient Internet of Things (A-IoT) device or an A-IoT tag, which is an IoT device powered by energy harvesting, and provides energy by collecting radio waves, light, motion, heat, or any other suitable power source. The second terminal 102 may be battery-free or have limited energy storage capacity (e.g., using a capacitor), and may use energy harvested from radio waves or any other form of energy available under specific circumstances. The second terminal 102 may transmit information based on backscatter communication technology.

[0098] In some embodiments, the second terminal 102 needs to collect radio waves sent by the network node to obtain energy before it can drive itself to work. Therefore, before obtaining energy, the IoT device is usually in a "powered off" state, that is, off-line.

[0099] In some embodiments, second terminal 102 can be classified into three types, as shown in FIG1B . Type A: Second terminal 102A has no energy storage and no independent signal generation / amplification, i.e., backscatter transmission. Type B: Second terminal 102B has energy storage but no independent signal generation, i.e., backscatter transmission; the use of stored energy may include amplification of reflected signals. Type C: Second terminal 102C has energy storage and independent signal generation, i.e., active radio frequency (RF) components for transmission.

[0100] In some embodiments, the second terminal 102 may be directly connected to the network device 103 .

[0101] In some embodiments, the second terminal 102 communicates with the first terminal 101 , and the first terminal 101 communicates with the network device 103 as an intermediate node.

[0102] In some embodiments, the network device 103 is, for example, a node or device that accesses the terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, an access node in a Wi-Fi system, an A-IoT reader, or at least one of an A-IoT base station, but is not limited thereto.

[0103] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0104] In some embodiments, the network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. 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.

[0105] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. 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 proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0106] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0107] 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).

[0108] In the disclosed embodiments, the A-IoT device may be battery-free or have limited power storage capacity (e.g., using a capacitor). Optionally, the A-IoT device may communicate without a traditional power source, and / or avoid human intervention in charging or replacing batteries. The device itself is capable of using energy obtained from radio waves, or any other form of energy that can be obtained under specific circumstances. A-IoT devices have the characteristics of low memory, low processing power, low power, small data transmission, and massive deployment. Since A-IoT devices do not require traditional batteries, they can work under extreme environmental conditions (e.g., high voltage, extremely high / low temperature, humid environment), and are maintenance-free, reducing operation and maintenance costs and having a longer service life.

[0109] 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.

[0110] In some embodiments, to support data transmission between A-IoT devices, the network needs to support the following functions. A device in the network may support one or more of the following functions:

[0111] The Energy Source (ES) function is only used for Type B and Type C A-IoT devices.

[0113] The Continuous Wave (CW) excitation function is only used for Type A and Type B A-IoT devices. A-IoT devices achieve uplink transmission by backscattering CW signals. CW is actually a type of ES. A-IoT devices can receive CW and store energy.

[0114] 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.
