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.

[0208] 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.

[0209] 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).

[0210] In today's IoT networks, traditional IoT devices are often powered by conventional batteries with limited lifespans, negatively impacting the user experience. The astronomical growth of IoT networks, coupled with the proliferation of IoT devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of conventional batteries are discarded annually, with only a small fraction effectively recycled, resulting in detrimental impacts on Earth's ecosystems. Maintaining IoT network operations and replacing batteries can be extremely challenging in extreme environmental conditions. Consequently, research is underway to develop battery-free IoT communications that will improve network performance and sustainability, while expanding their application scenarios. Furthermore, battery-free communications are 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. IoT powered by ambient power is a promising technology that can address these needs.

[0211] In some embodiments, backscatter communication is one of the key technologies for building a passive Internet of Things.

[0212] Backscatter communication is an extremely low-power modulation and transmission technology designed using the principle of RF signal backscattering. Since RF signals are partially reflected when they reach surfaces, the transmitting device can adjust the matching between the receiving antenna and the impedance according to the intended transmission information to enhance the transmission of the incident RF signal. The device then modulates the acquired sensor data onto the reflected signal to complete the data transmission.

[0213] Compared with other communication technologies, backscatter communication can be implemented without complex RF structure, which can reduce the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, high-precision filters, etc. It also does not require complex baseband processing processes, which can simplify the design of terminal equipment and reduce equipment costs.

[0214] Backscatter communication is widely used in Radio Frequency Identification (RFID) systems. A receiver (such as an RFID reader) can send a radio frequency signal to activate a passive node (such as an RFID tag). The passive node then uses backscatter communication to modulate its own information onto the radio frequency signal to transmit the information. After receiving the reflected signal from the passive node, the receiver can demodulate the reflected signal to read the information.

[0215] In some embodiments, a communication process similar to that of an RFID system can be adopted to implement the communication design of an Ambient IOT system based on reflection scattering technology.

[0216] In some embodiments, the Ambient IoT system may support multiple types of Ambient IoT devices.

[0217] In some embodiments, the Ambient IOT system may support two types of Ambient IOT devices: type 1 and type 2.

[0218] Type 1 Ambient IoT devices have energy storage but lack independent signal generation and amplification, relying on backscatter for uplink transmission. Type 2 Ambient IoT devices, on the other hand, have energy storage and independent signal amplification, and their uplink transmission can be generated internally or rely on backscatter.

[0219] In some embodiments, type 2 Ambient IoT devices can be further divided into type 2a (type 2a) and type 2b (type 2b).

[0220] Type 2a Ambient IoT devices have energy storage and independent signal amplification, and their uplink transmission relies on backscattering. Type 2b Ambient IoT devices have energy storage and independent signal amplification, and their uplink transmission can be based on internally generated signals.

[0221] In some embodiments, the Ambient IOT system can support multiple network topologies.

[0222] Refer to Figure 2A, which is a network topology diagram of an Ambient IOT system 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, data (including uplink data and downlink data) can be directly sent and received between the Ambient IOT device and the base station.

[0223] Refer to Figure 2B, which is a network topology diagram of another Ambient IOT system 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, data (including uplink data and downlink data) can be indirectly sent and received between the Ambient IOT device and the base station, and the intermediate node can play the function of data forwarding between the Ambient IOT device and the base station.

[0224] It should be noted that the above are only two exemplary network topologies and do not constitute a limitation on the network topology of the Ambient IOT system.

[0225] In some embodiments, in the network topology shown in FIG2A , Ambient IoT devices can directly communicate bidirectionally with a base station to transmit ambient IoT information (including data and / or signals). However, due to interference issues caused by the base station's self-transmission and self-reception, it may be considered to use a base station different from the base station that sends command messages to the Ambient IoT device as the base station for receiving response messages from the Ambient IoT device.

[0226] It should be noted that, when the base station that sends the command message to the Ambient IOT device is different from the base station that receives the response message from the Ambient IOT device, it is necessary to clarify how the base station that receives the response message forwards the received response message.

[0250] For example, the device capability of the first Ambient IOT device may be configured to only allow communication devices of a specific type to be used as the first communication device. Then, the first Ambient IOT device may determine a communication device of the specific type as the first communication device based on the device capability of the first Ambient IOT device.

[0310] In some embodiments, the name of the fifth indication information is not limited, and it can be, for example, "Ambient IOT command response indication information" or the like.

[0311] Step S3103: The first communication device forwards a response message of the first command to the second communication device based on the first information.

[0312] In some embodiments, the first communication device may determine the second communication device associated with the response message of the first command based on the first information, thereby forwarding the response message of the first command to the second communication device.

[0313] For ease of understanding, the communication method provided by the embodiments of the present disclosure is described below with reference to several examples.

[0314] In some embodiments, the ambient IoT device may send first information to the first communication device. The first communication device may determine the second communication device to which the response message of the first command is to be sent based on the indication of the first information, and thereby send the response message of the first command to the second communication device.

[0315] In some embodiments, the fifth communication device (such as an OAM device, an intermediate node, an access network device, a core network device, an Ambient IOT server) sends the first information to the first communication device, and can send the first information to the first communication device. The first communication device can determine the second communication device to which the response message of the first command is to be sent based on the indication of the first information, thereby sending the response message of the first command to the second communication device.

[0316] Optionally, the first information may include at least one of first indication information, second indication information, third indication information, fourth indication information and fifth indication information.

[0317] Taking the example that the first information includes the first indication information, when the first communication device forwards the response message of the first command according to the indication of the first information, it can determine the Ambient IOT device associated with the first command according to the indication of the first indication information, and thus determine the second communication device to receive the response message sent by the Ambient IOT device based on the device capabilities of the Ambient IOT device associated with the first command. If the determined second communication device is a different device from the first communication device, the first communication device can determine that the response message is not to be sent to itself, and thus forward the response message of the first command to the second communication device.

[0318] Taking the example that the first information includes the first indication information and the fifth indication information, when the first communication device forwards the response message of the first command according to the indication of the first information, it can directly determine that the response message of the first command needs to be forwarded according to the fifth indication information, and can determine the Ambient IOT device associated with the first command according to the indication of the first indication information, and thus determine the second communication device to receive the response message sent by the Ambient IOT device based on the device capabilities of the Ambient IOT device associated with the first command, so as to forward the response message of the first command to the second communication device.

[0319] Taking the example of the first information including the second indication information, when the first communication device forwards the response message of the first command according to the indication of the first information, it can determine the Ambient IOT device associated with the first command according to the indication of the second indication information, and thus determine the second communication device to receive the response message sent by the Ambient IOT device based on the device capabilities of the Ambient IOT device associated with the first command. If the determined second communication device is a different device from the first communication device, the first communication device can determine that the response message is not to be sent to itself, and thus forward the response message of the first command to the second communication device.

[0320] Taking the example that the first information includes the second indication information and the fifth indication information, when the first communication device forwards the response message of the first command according to the indication of the first information, it can directly determine that the response message of the first command needs to be forwarded according to the fifth indication information, and can determine the Ambient IOT device associated with the first command according to the indication of the second indication information, and thus determine the second communication device to receive the response message sent by the Ambient IOT device based on the device capabilities of the Ambient IOT device associated with the first command, so as to forward the response message of the first command to the second communication device.

[0321] Taking the example of the first information including the third indication information, when the first communication device forwards the response message of the first command according to the indication of the first information, it can determine the second communication device according to the indication of the third indication information. If the determined second communication device is a different device from the first communication device, the first communication device can determine that the response message is not to be sent to itself, thereby determining the second communication device to which the response message of the first command is to be sent.

[0322] Taking the example that the first information includes the third indication information and the fifth indication information, when the first communication device forwards the response message of the first command according to the indication of the first information, it can directly determine the need to forward the response message of the first command according to the fifth indication information, and can implement the determination of the second communication device according to the indication of the third indication information to forward the response message of the first command to the second communication device.

[0323] Taking the example of the first information including the fourth indication information, when the first communication device forwards the response message of the first command according to the indication of the first information, it can determine the communication device allowed to receive the response message of the first command according to the indication of the fourth indication information, thereby determining the second communication device based on the determined communication device. If the determined second communication device is a different device from the first communication device, the first communication device can determine that the response message is not to be sent to itself, and thus forward the response message of the first command to the second communication device.

[0324] Taking the example that the first information includes the fourth indication information and the fifth indication information, when the first communication device forwards the response message of the first command according to the indication of the first information, it can directly determine that the response message of the first command needs to be forwarded according to the fifth indication information, and can determine the communication device allowed to receive the response message of the first command according to the indication of the fourth indication information, so as to forward the response message of the first command to the second communication device.

[0325] The above are merely several exemplary implementations of the first communication device forwarding the response message to the first command according to the instruction of the first information, and do not constitute a limitation to the embodiments of the present disclosure.
