[0169] 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.

[0170] 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.

[0171] 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), 6th generation mobile communication system (6G), 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).

[0172] Among related technologies, Ambient IoT, as an advanced Internet of Things (IoT) technology, allows Ambient IoT devices to operate without built-in batteries or external power sources. They rely solely on external power for activation and data transmission, thus avoiding the maintenance costs and hassles of periodically replacing batteries, reducing operating costs, and minimizing energy consumption and the environmental impact of battery use. Furthermore, Ambient IoT devices are small in size, easily integrated into various objects, and can be conveniently deployed in diverse environments.

[0173] 6G IoT technology, as an IoT technology that promises higher data transmission speeds, lower latency, greater connection density, and more reliable communication, enables IoT devices to transmit and communicate more quickly and stably, further promoting the network speed, capacity, and connectivity of IoT technology, and providing better support for more smart devices and IoT applications.

[0174] Therefore, Ambient IoT technology and 6G IoT technology have become two important research directions for future Internet of Things (IoT) technologies.

[0175] In some embodiments, Ambient IoT devices and IoT devices can access the network in multiple ways. Taking Ambient IoT devices as an example, Ambient IoT devices can access the network in the following two ways.

[0176] Referring to Figure 2A, which is a network topology diagram according to an embodiment of the present disclosure, taking the access network device as a base station as an example, as shown in Figure 2A, the Ambient IoT device and the base station can directly transmit and receive data (including uplink data and downlink data).

[0177] Referring to Figure 2B, which is a schematic diagram of another network topology according to an embodiment of the present disclosure, taking the access network device as a base station as an example, as shown in Figure 2B, the Ambient IoT device and the base station can indirectly transmit and receive data (including uplink data and downlink data), and the intermediate node can play the role of data forwarding between the Ambient IoT device and the base station.

[0178] It should be noted that the above are only two exemplary access methods and do not constitute a limitation on the access methods of Ambient IoT devices.

[0179] In some embodiments, Ambient IoT devices can be divided into two types: Type 1 and Type 2.

[0180] Type 1 Ambient IoT devices have energy storage but lack independent signal generation and amplification, relying on backscattering for uplink transmission. Type 2 Ambient IoT devices, on the other hand, have energy storage and independent signal amplification; uplink transmission can be generated internally or achieved through backscattering.

[0181] In some embodiments, type 2 Ambient IoT devices can be further divided into type 2a (type 2a) and type 2b (type 2b).

[0182] Among them, type 2a Ambient IoT devices have energy storage and independent signal amplification, and uplink transmission relies on backscattering. Type 2b Ambient IoT devices, on the other hand, have energy storage and independent signal amplification, and uplink transmission can be achieved based on internally generated signals.

[0183] It should be noted that the data storage or energy storage capacity of any Ambient IoT device is limited. Furthermore, the data storage or energy storage capacity of 6G IoT devices is also limited. In scenarios involving long-cycle command interactions and large-scale data transmission, insufficient energy storage or storage space may prevent the completion of the entire business process. Therefore, how to complete long-cycle command reception and large-scale data transmission under limited device capabilities is a problem that needs to be considered.

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).

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).
