[0052] In the above embodiment, since the first information indicates the terminal capability of the terminal, and the terminal capability includes the capability determined based on the endurance energy of the terminal, the first communication node can perform data scheduling operations based on the endurance energy of the terminal. Compared with the case where the first information is not sent to the first communication node, the first communication node can perform data scheduling operations that adapt to the terminal capability.

[0053] In combination with some embodiments of the first aspect, in some embodiments, the first information is used by the first communication node to trigger the terminal to send data.

[0168] 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).

[0169] In some cases, IoT devices in IoT networks are often powered by traditional batteries with limited lifespans, negatively impacting 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 traditional batteries are discarded each year, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in extreme environmental conditions. Battery-free IoT communications have been proposed to improve network performance and sustainability, expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. Eliminating traditional batteries significantly reduces device size and cost, paving the way for a variety of new applications.

[0170] In some embodiments, in the era of the fifth generation mobile communication technology 5G, various low power wide area (LPWA) technologies have been developed, such as machine type communication (MTC), narrowband Internet of Things (NB-IoT), reduced capability (RedCap), etc., to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption and large-scale connectivity, which can meet the requirements of many applications. However, there are still many use cases and applications that cannot be solved in the following situations. First, devices driven by traditional batteries are not applicable, such as in extreme environmental conditions (such as high voltage, extremely high / low temperature, humid environment). Second, maintenance-free equipment is required (for example, there is no need to replace traditional batteries of the device). Finally, ultra-low complexity, very small device size / form factor (such as mm thickness), longer life cycle, etc. are required.

[0171] In some embodiments, ambient powered IoT is a promising technology that can address the unmet needs described above. An ambient powered IoT device is an IoT device that is powered by energy harvesting, either without a battery or with limited energy storage capabilities (e.g., using capacitors), by harvesting radio waves, light, motion, heat, or any other suitable power source.

[0172] In some embodiments, energy harvested from the environment can drive data transmission and wireless communications among sensor nodes. Current mainstream low-power IoT communication chips consume tens or even hundreds of milliwatts of power for both transmission and reception, while ambient energy harvesting only captures microwatts, making them inadequate for powering these nodes. Therefore, new wireless communication technologies are needed to reduce communication energy consumption to tens or even below ten microwatts. Backscatter communications, currently a mainstream approach, is a key technology for building a green, energy-efficient, and flexibly deployable future IoT, and a crucial means of achieving the "Intelligent Connection of Everything."

[0173] In some embodiments, as shown in Figure 1b, backscatter communication utilizes the principle of RF signal backscattering to design an extremely low-power modulation and transmission technology. Backscatter communication was first proposed by Stockman. Since a portion of the RF signal is reflected when it reaches an object's surface, the transmitting node adjusts the matching between the receiving antenna and the impedance according to the intended information to enhance the reflection of the incident RF signal. It then modulates the acquired sensory data onto the reflected signal to complete the data transmission. This process is similar to a reflector. Compared to other communication technologies, backscatter communication does not require complex RF structures, reducing the use of components such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing, thereby simplifying terminal design and significantly reducing terminal node costs.

[0174] In some embodiments, backscatter communication has been widely used in Radio Frequency Identification (RFID) systems, resulting in numerous large-scale commercial applications. Its operating principle is that a receiver (typically an RFID reader) transmits a radio frequency excitation signal, activating a passive node (typically an RFID tag). The tag then uses backscatter communication to modulate its information onto the radio frequency signal. The reader then receives the reflected signal from the passive tag and demodulates it, achieving information transmission.

[0175] In some embodiments, RFID technology also has numerous drawbacks, such as limited coverage (the wireless signal experiences double-path fading during the round-trip communication process, resulting in high path loss and a short effective communication range), single-channel transmission, the need for strict tag alignment, and a lack of power control. RFID technology still has significant room for improvement in communication. Integration with 3GPP communication technologies is needed to improve the wireless communication performance of RFID technology in the passive IoT.

[0176] The expected new type of IoT devices have the characteristics of low memory, low processing power, low power consumption, small data transmission, and massive deployment. Environmental IoT devices can be maintenance-free and have a long service life (for example, more than 10 years).

[0177] These new IoT devices require energy from radio waves transmitted by network nodes to power themselves. Therefore, until they receive energy, they are typically powered off, meaning they are disconnected from the network. To address this, the communication system must support data communication methods with shorter transmission times, lower memory consumption, and more convenient terminal management to expedite data communication.

[0178] In some embodiments, see FIG1c, which shows a network architecture for wireless communication based on backscatter technology to achieve communication between ambient energy devices.

[0179] Architecture 1: Direct downlink (DL) and uplink (UL) data reception and transmission between ambient power IoT devices and base stations.

[0180] Architecture 2: DL and UL data reception and transmission are performed indirectly between the ambient IoT and the base station; intermediate nodes exist in the middle to forward data. For example, the intermediate nodes can be relays, integrated access backhaul (IAB), UEs, and repeaters.

[0181] Architecture 3: Ambient IoT and the base station directly transmit or receive data in the DL or UL. Auxiliary nodes are located on the UL or DL, responsible for receiving or sending UL or DL ​​data. Examples of auxiliary nodes include relays, IABs, UEs, and repeaters.

[0182] Architecture 4: Direct DL and UL data reception and transmission between ambient IoT and UE; UE is responsible for collecting data and forwarding it to the network.

[0183] In some embodiments, referring to FIG1d , Ambient IoT devices can be divided into three types:

[0184] Device A: No energy storage, no independent signal generation / amplification, i.e. backscatter transmission;

[0185] Device B: has energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy may include amplification of the reflected signal.

[0186] Device C: has energy storage and independent signal generation, i.e., active RF components for transmission.

[0187] In some embodiments, a terminal reports its wireless capabilities based on a network request to report terminal capabilities information. A reduced-capability terminal (Redcap) message can also simply indicate the terminal type, such as the Redcap type, in message 1 (MSG1) or message 3 (MSG3). A terminal's wireless capabilities are those related to the initial wireless data transmission of the terminal.

[0188] In some embodiments, there's no need to temporarily acquire energy for data transmission. The interval between data transmissions is related to charging capacity, and the speed of charging affects the time it takes for the network to trigger the next data report. This type of terminal capability definition and reporting doesn't exist in existing mobile communication systems.

[0189] In some embodiments, for passive IoT terminals, different terminal types and capacitor sizes can affect the terminal's data transmission capabilities and the interval between data transmissions. The present invention defines the terminal's data transmission capabilities and reports them to the network, assisting the network in effectively triggering the terminal to report data.

[0223] In some embodiments, the first communication node receives first information sent by the terminal.

[0224] In some embodiments, the first information may be indication information.

[0225] In some embodiments, in response to performing the initial backscatter, the terminal sends the first information to the first communication node.

[0226] In some embodiments, the first information indicates terminal capabilities of the terminal.

[0227] In some embodiments, the terminal capabilities include capabilities determined based on the endurance energy of the terminal.

[0228] In some embodiments, the first information is used by the first communication node to trigger the terminal to send data.
