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.

[0224] 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.

[0225] 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).

[0226] In today's IoT networks, traditional IoT devices are typically powered by conventional batteries with limited lifespans, negatively impacting user experience. The astronomical growth of IoT networks, coupled with the sheer number of IoT devices, has pushed maintenance costs, including labor and battery expenses, to unprecedented levels. Billions of conventional batteries are discarded annually, with only a fraction being effectively recycled, causing harmful impacts on the Earth's ecosystem. Maintaining IoT networks and replacing batteries can be extremely challenging under extreme environmental conditions. Therefore, research aims to develop a battery-free IoT communication approach to improve network performance and sustainability, and expand application scenarios. Furthermore, battery-free communication is more environmentally friendly and safer for children and the elderly. Eliminating conventional batteries can significantly reduce device size and cost, paving the way for a variety of new applications. IoT powered by ambient electricity is a promising technology that can meet these needs.

[0227] In some embodiments, backscatter communication is one of the key technologies for building passive Internet of Things (IoT).

[0228] It should be noted that backscatter communication is an extremely low-power modulation and transmission technology designed using the principle of backscattering radio frequency signals. Since a portion of the radio frequency signal is reflected when it reaches the surface of an object, the transmitting device can adjust the matching between the receiving antenna and impedance according to the information to be transmitted, thereby enhancing the transmission of the incident radio frequency signal. It then modulates the sensed data it acquires onto the reflected signal to complete the data transmission.

[0229] Compared to other communication technologies, backscatter communication can be implemented without complex radio frequency structures, which can reduce the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing, which can simplify the design of terminal equipment and reduce equipment costs.

[0230] Backscatter communication can be 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 can then use 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.

[0231] In some embodiments, a communication process similar to that of an RFID system can be adopted to implement the communication design of the Ambient IoT system based on reflection scattering technology.

[0232] In some embodiments, the Ambient IoT system can support multiple types of Ambient IoT devices.

[0233] In some embodiments, the Ambient IoT system can support both Type 1 and Type 2 Ambient IoT devices.

[0234] 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.

[0235] In some embodiments, type 2 Ambient IoT devices can be further divided into type 2a (type 2a) and type 2b (type 2b).

[0236] 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.

[0237] In some embodiments, the Ambient IoT system can support multiple network topologies.

[0238] Referring 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, the Ambient IoT device and the base station can directly transmit and receive data (including uplink data and downlink data).

[0239] Referring 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 the 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.

[0240] 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.

[0241] In some embodiments, in the network topology shown in FIG2A, the access network device (i.e., the base station) can be used as the Reader, and the Reader can send Reader to Device (R2D) messages to the Ambient IoT device.

[0242] In some embodiments, in the network topology shown in Figure B, an intermediate node can be used as a Reader to send R2D messages to the Ambient IoT device.

[0243] In some embodiments, regardless of the type of Reader that sends the R2D message to the Ambient IoT device, the Ambient IoT device can initiate a process similar to random access to access the Reader after receiving the R2D message, and then proceed with subsequent data transmission.

[0244] In some embodiments, to accelerate the interaction process in an Ambient IoT system, it may be considered to transmit uplink (UL) data during the access process. However, UL data can not be sent during the access process in all cases.

[0245] In view of this, embodiments of the present disclosure aim to provide a communication method to help Ambient IoT devices determine under what circumstances UL data can be sent during the access process.

[0246] Figure 3 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiments of the present disclosure relate to a communication method, which includes:

This can be data sent from the first Ambient IoT device to other communication devices; that is, uplink data can be data from the first Ambient IoT device to other communication devices. For example, data from the first Ambient IoT device to a reader, data from the first Ambient IoT device to access network equipment (such as a base station), data from the first Ambient IoT device to core network equipment (such as core network functional nodes), and data from the first Ambient IoT device to an Ambient IoT server can all be referred to as uplink data.

[0258] The first indication information can be determined by the first communication device.

[0260] That is, the first communication device can determine the first indication information based on information related to the uplink data. Alternatively, the first communication device can determine the first indication information based on the signal quality of the received second signal. Or, the first communication device can determine the first indication information based on both information related to the uplink data and the signal quality of the received second signal.
