Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0191] 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.

[0192] 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.

[0193] 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.

[0194] 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."

[0195] In some embodiments, please refer to Figure 1b. Backscatter communication is a modulation and transmission technology designed with extremely low power consumption, which utilizes the principle of backscattering of radio frequency signals. Backscatter communication was first proposed by Stockman. When the radio frequency signal reaches the surface of an object, a part of it will be reflected. The sending node adjusts the matching between the receiving antenna and the impedance according to the information to be sent, thereby enhancing the reflection of the incident radio frequency signal and modulating the perception data acquired by itself onto the reflected signal to complete the transmission of the data. This process is similar to that of a reflector. Compared with other communication technologies, backscatter communication does not require a complex radio frequency structure, reduces the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters, and does not require complex baseband processing. Therefore, it can simplify terminal design and significantly reduce the cost of terminal nodes.

[0196] 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.

[0197] 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.

[0198] 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).

[0199] 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.

[0200] In some embodiments, see FIG1c, which shows a network architecture for wireless communication based on backscatter technology to achieve communication between ambient energy devices.

[0201] Architecture 1: Direct downlink (DL) and uplink (UL) data reception and transmission between ambient power IoT devices and base stations.

[0202] 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.

[0203] 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.

[0204] 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.

[0205] In some embodiments, referring to FIG1d , Ambient IoT devices can be divided into three types:

[0206] Device A: No energy storage, no independent signal generation / amplification, i.e. backscatter transmission;

[0207] 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.

[0208] Device C: has energy storage and independent signal generation, i.e., active RF components for transmission.

[0209] In some embodiments, a terminal reports 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. Currently, a terminal's wireless capabilities are those related to the initial wireless data transmission of the terminal.

[0210] In some embodiments, if a terminal wants to send uplink data but lacks UL resources, it can request the network to allocate UL resources by sending a Random Access Channel (RACH) procedure or a Scheduling Request (SR). Both the RACH procedure and the SR require periodic resource availability. Currently, terminals can generate their own signals and simply send information on the nearest physical Random Access Channel (RO) opportunity or SR resource.

[0211] In some embodiments, since the terminal can generate its own signals, it only needs to send signals on UL resources to contact the network to obtain UL resource allocation for data transmission. However, the backscatter-based data communication process requires an excitation signal from the network to enable uplink data transmission. If the terminal does not have a capacitor to store energy, it cannot amplify the power when performing backscatter based on the excitation signal. Therefore, the excitation signal generated by the base station and received by the base station will experience a round-trip path loss.

As shown in Figure 5a, the present disclosure embodiment relates to an information indication method, which is used in a communication system 100 and includes one of the following steps:

[0380] Step S5101: The terminal sends first information to the first communication node;

[0381] The first information is used to request the first communication node to trigger the terminal to send data in a first manner.

[0382] The optional implementation of step S5101 can refer to the optional implementation of step S2101 in Figure 2a and other related parts of the embodiment involved in Figure 2a, which will not be repeated here.

[0384] Figure 6a is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in Figure 6a, the embodiment of the present disclosure relates to an information indication method, which includes:

[0385] Step S6101: The first communication node sends a first signal to the terminal.

[0386] In some embodiments, the first communication node may be a gNB or a UE.

[0387] In some embodiments, the terminal is an ambient IOT.

[0388] In some embodiments, the gNB or UE sends a periodic signal, which is used to provide the ambient IoT with uplink data to send. Based on this periodic excitation signal, the gNB or UE can request the network side to trigger data request reporting.

[0389] Step S6102: The terminal sends first information to the first communication node.

[0390] In some embodiments, the ambient IOT selects a periodic excitation signal and sends it via backscattering. During the backscattering transmission process, it carries a random sequence, or a random string, or a random number, etc., which is mainly used to temporarily identify the ambient IOT.

[0391] Step S6103: The first communication node sends second information to the terminal.

[0392] In some embodiments, after receiving the backscattered data transmission from the ambient IoT, the gNB or UE sends an excitation signal for a data request, where the excitation signal carries the received random sequence, random string, or random number, and assigns a network temporary ID, i.e., ID, to the ambient IoT.

[0393] Step S6104: The terminal sends third information to the first communication node.

[0394] In some embodiments, after receiving the excitation signal, the ambient IoT uses the random sequence, random string, or random number sent back by the gNB / UE to identify the data request service sent by the network in response to its request.

[0395] In some embodiments, the Ambient IOT stores the ID and carries the ambient IOT ID and / or data (e.g., sensor data or event type, or event, etc.) and / or ID via backscatter. The ID is used to allow the network to confirm that the data report is the previously requested data report.

[0396] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0397] FIG6b is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG6b , the embodiment of the present disclosure relates to an information indication method, and the method includes:

[0398] Step S6201: The first communication node sends a first signal to the terminal.

[0399] In some embodiments, the first communication node may be a gNB or a UE.

[0400] In some embodiments, the terminal is an ambient IOT.

[0401] In some embodiments, the gNB or UE sends a periodic signal, which is used to provide an ambient IOT with uplink data to send. Based on this periodic excitation signal (corresponding to the first signal in the present disclosure), the network side can be requested to trigger data request reporting.

[0402] Step S6202: The terminal selects a periodic excitation signal according to the terminal type.

[0403] In some embodiments, the periodic excitation signal is divided into at least two types, each for a different terminal type, for example, two different periodic excitation signals, one for device A and the other for device B. The periodic excitation signals for different terminal types can be distinguished by two independent sets of configurations, or configuration information carried in the periodic excitation signal, the configuration information being used to configure the terminal type (ambient IoT type) to which it belongs.

[0404] Step S6203: The terminal sends first information to the first communication node.

[0405] In some embodiments, the ambient IOT selects a periodic excitation signal according to its own terminal type and sends it by backscattering. During the backscattering transmission process, it carries a random sequence, or a random string, or a random number, etc., which is mainly used to temporarily identify the ambient IOT.

[0406] Step S6204: The first communication node determines the transmission power of the second signal according to the terminal type.

[0407] The gNB or UE determines the terminal type based on the received backscatter signal and determines the transmit power for the next signal based on the terminal type. For example, for device A, since it does not have a power amplifier, the power of the periodic signal can be greater than the power threshold.

[0408] Step S6205: The first communication node sends second information to the terminal.

[0409] In some embodiments, after receiving backscattered data from an ambient IoT device, the gNB or UE can determine the device type based on the original backscattered signal and determine the power level for subsequent transmissions. For example, for device A without amplification, the power level of the periodic signal can be higher.

[0410] Step S6206: The terminal sends third information to the first communication node.

[0411] In some embodiments, after receiving the excitation signal, the ambient IoT uses the random sequence, random string, or random number sent back by the gNB or UE to identify the data request service sent by the network in response to its request.

[0412] In some embodiments, the Ambient IOT stores the ID and carries the ambient IOT ID and / or data (e.g., sensor data or event type, or event, etc.) and / or ID via backscatter. The ID is used to allow the network to confirm that the data report is the previously requested data report.

[0413] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0414] Figure 6c is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in Figure 6c, the embodiment of the present disclosure relates to an information indication method, which includes:

[0415] Step S6301: The first communication node sends a first signal to the terminal.

[0416] In some embodiments, the gNB or UE sends a periodic signal, which is used to provide the ambient IoT with uplink data to send. Based on this periodic excitation signal, the gNB or UE can request the network side to trigger data request reporting.

[0417] Step S6302: The terminal sends first information to the first communication node.

[0418] In some embodiments, the ambient IoT selects a periodic excitation signal and sends it backscattered. During the backscatter transmission, the signal carries a random sequence, a random string, or a random number, primarily used to temporarily identify the ambient IoT. It also carries the terminal type (e.g., device A or device B).

[0419] Step S6303: The first communication node determines the transmission power of the second signal according to the terminal type.

[0420] In some embodiments, the transmit power of the next signal is determined based on the terminal type. For example, for device A, since it does not have a power amplifier, the power of the periodic signal may be greater than the power threshold.

[0421] Step S6304: The first communication node sends second information to the terminal.

[0422] In some embodiments, after receiving the ambient IoT backscattered data transmission, the gNB or UE obtains the terminal type information and determines the power of the next transmission. For example, for device A without amplification, the power of the periodic signal can be higher.

[0423] In some embodiments, an excitation signal for a data request is sent, the excitation signal carrying a received random sequence, or a random string, or a random number, and a network temporary ID, ie, ID, is assigned to the ambient IOT.

[0424] Step S6305: The terminal sends third information to the first communication node.

[0425] In some embodiments, after receiving the stimulus signal, the ambient IoT uses the random sequence, random string, or random number sent back by the gNB / UE to identify the data request service as being issued by the network in response to its request. The ambient IoT stores the ID and carries the ambient IoT ID and / or data (e.g., sensor data, event type, or event), and / or ID via backscatter. This ID allows the network to confirm that the data report is the one previously requested.

[0426] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
