[0174] In some cases, some IoT devices are often powered by traditional 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 traditional batteries are discarded each year, with only a small fraction effectively recycled, which has a detrimental impact on Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in some extreme environmental conditions. Battery-free IoT communications have been proposed to improve network performance and sustainability, and expand application scenarios. Furthermore, battery-free communications are more 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.

[0175] 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.

[0176] 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.

[0177] In some embodiments, energy obtained from the environment can drive data transmission and wireless communication of sensing nodes. The current mainstream low-power IoT communication chips (such as Bluetooth Low Energy (BLE), LoRa, and NB-IoT) have a transmit and receive power consumption of tens or even hundreds of milliwatts, while the energy obtained by environmental energy harvesting is only in the microwatt level, which is unable to drive these types of nodes. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens of microwatts or even less than ten microwatts. The current mainstream method uses backscatter communication technology. Backscatter Communications is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things, and is an important means to achieve the "Intelligent Connection of Everything".

[0178] In some embodiments, please refer to FIG1B , backscatter communication is a modulation and transmission technology designed with extremely low power consumption using 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 portion 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 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.

[0179] 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.

[0180] In some embodiments, RFID technology also has numerous drawbacks, such as short coverage distance (the wireless signal experiences double-path fading during round-trip communication, 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.

[0181] This new type of IoT device needs to 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).

[0182] 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.

[0183] In some embodiments, a network topology architecture for wireless communication based on ambient energy devices is implemented based on backscatter technology. For example, the network topology construction may include one of the following:

[0184] Topology 1: See Figure 1C. Downlink (DL) and uplink (UL) data are directly received and transmitted between the ambient power IoT device and the base station.

[0185] Topology 2: As shown in Figure 1D , the ambient IoT and the base station indirectly receive and transmit DL and UL data. Intermediary nodes are present for forwarding. For example, the intermediate nodes can be relays, integrated access backhaul (IAB), user equipment (UE), and / or repeaters.

[0186] Topology 3: Referring to Figure 1E , the 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 transmitting UL or DL ​​data. Examples of auxiliary nodes include relays, IABs, UEs, and / or repeaters.

[0187] Topology 4: See Figure 1F. Downlink and uplink data are directly received and transmitted between the ambient IoT and the UE. The UE collects data and forwards it to the network.

[0188] In some embodiments, referring to FIG. 1G , Ambient IoT devices can be divided into three types:

[0189] Device A: No energy storage, no independent signal generation or amplification, i.e. backscatter transmission;

[0190] Device B: has energy storage but no independent signal generation, i.e. backscatter transmission. Utilization of stored energy may include amplification of the reflected signal.

[0191] Device C: has energy storage and independent signal generation, that is, an active radio frequency (RF) component for transmission.

[0192] In some embodiments, the network side triggers the mobile terminal (mobile terminated, MT) or the terminal triggers the calling party (Mobile Origination Call, MO). Regardless of the type, the network and the terminal first establish a dedicated connection, and data interaction is performed after the access layer (Access Stratum) layer security is activated. Optionally, in the Multicast & Broadcast Service (MBS), the network side can trigger the users in the MBS group to enter the Radio Resource Control (Radio Resource Control, RRC) connection state through group paging based on the group paging method, and then send the multicast data. The users in the group are all legitimate users maintained by the non-access stratum (NAS) layer signaling.

[0193] In some embodiments, there is no scenario where the network side triggers a group of users, and this group of users is unknown to the network side.

[0194] In some embodiments, the network triggers a data request based on a set of AIoTs (e.g., based on a service ID). However, the cell doesn't know if some AIoTs are missing, for example, due to out-of-coverage or poor channel conditions, or insufficient power. Therefore, how to handle missed AIoTs and what the network does next after an inventory attempt are key issues. For example, after an inventory attempt, should the data request be initiated again?

[0195] The disclosed embodiments can first perform an inventory of passive IoT terminals (e.g., environmental IoT) and then perform an inventory for each environmental IoT. This minimizes the problem of missed inventory. Optionally, if a missed inventory is found, the network can trigger the inventory command again, while terminals that have already been inventoried can ignore this inventory, thereby achieving the goals of energy conservation, interference reduction, and air interface resource conservation in the environmental physical network.

[0435] In some embodiments, the above method may include the method described in the above-mentioned embodiments of the information processing system 100 side, the first device side, the network device side, etc., which will not be repeated here.

[0436] The present disclosure relates to an information processing method, which includes:

[0437] In the following embodiments, the base station may be replaced by a relay, an IAB, a UE or a repeater. Alternatively, the base station, the relay, the IAB, the UE or the repeater may be the network device in the previous embodiments.

[0438] Step S6101, quantity inventory.

[0439] In some embodiments, the network sends a request to trigger a headcount. Any Ambient IoT device receiving this request will perform backscattering or determine whether to participate based on the RSRP threshold configured by the network. Optionally, the request also includes a sequence or sequence index, which is used by the device to carry the sequence when performing backscattering, to assist the network in calculating the number of devices that have responded to the request.

[0440] In some embodiments, the environmental Internet of Things performs backscattering to take inventory of the number of participants. Optionally, the environmental Internet of Things performs backscattering at maximum power, which may include one of the following backscattering methods:

[0441] Method 1: The environmental IoT performs backscattering based on the sequence configured on the network side or the sequence corresponding to the sequence index.

[0442] Method 2: The environmental IoT performs cyclic shift based on the default sequence index, the sequence index configured on the network side, the sequence configured on the network side, and / or the environmental IoT identifier to confirm the sequence used for backscattering.

[0443] Method 3: The environmental IoT preconfigures a sequence, which is used to backscatter data during quantity inventory.

[0444] Method 4: The environmental IoT does not load any data and directly backscatters the excitation signal from the network side.

[0445] In some embodiments, based on at least one of the first, second, and third methods, the network side knows the correspondence between sequences and sequence indexes, as well as a set of sequences; for example, the system supports a total of 512 sequences for quantity inventory.

[0446] In some embodiments, the network side determines the total number of ambient IoTs based on the backscatter of all ambient IoTs, i.e., the inventory number.

[0447] In some embodiments, any information carried by the network side, such as the purpose of the excitation signal, quantity inventory, sequence or sequence index, etc., can be carried in the MAC header, or in the MAC payload, or in the MAC CE.

[0448] Optionally, the request sent by the network side can be the third signal in the previous embodiment; the sequence and sequence index carried in the request can be the first sequence and first sequence index in the previous embodiment respectively; the backscattering performed by the environmental Internet of Things can be the fourth signal in the previous embodiment; the sequence carried in the backscattering performed by the environmental Internet of Things can be the second sequence in the previous embodiment; the purpose of the excitation signal can be the third indication information in the previous embodiment.

[0449] Step S6102: Based on the network-side auxiliary information, determine whether to participate in the inventory based on the task ID and value tag.

[0450] In some embodiments, the network side issues a member inventory command, which includes the following information, such as information about the target member to be inventoried, such as a service ID, a service group ID, an environmental IoT group ID, etc. Optionally, it may also include a task ID and / or an inventory value tag and / or information indicating a missing disk. Optionally, the service ID is used to identify the task to be executed by the first device.

[0451] Optionally, the task identifier is the task serial number assigned by the network for each inventory task. The inventory value identifier represents the label of the current inventory task. If the current inventory task is triggered repeatedly, for example, to trigger a missed terminal to continue reporting data, the inventory value identifier remains unchanged. If the inventory task is executed again, such as a new inventory, the inventory value identifier increments by 1.

[0452] Optionally, if the environmental Internet of Things receives the inventory task for the first time, it saves the task identifier and / or inventory value identifier; determines whether it is an inventory command repeatedly triggered by the missed disk terminal based on the task identifier and / or inventory value identifier; if so, and the environmental Internet of Things has completed the inventory, it ignores the inventory command; otherwise, it responds to the inventory command, performs backscattering, and reports data.

[0453] Exemplarily, as shown in Figure 6, the base station or UE (gNB / UE) sends a quantity inventory command to the ambient Internet of Things (Ambient IOT); the ambient Internet of Things performs backscatter transmission to the base station or UE; the base station or UE sends a member inventory command, which includes a service identifier or an ambient Internet of Things group identifier, and a task identifier or an inventory value identifier; the ambient Internet of Things performs backscatter transmission to the base station or UE, and the backscatter transmission includes the ambient Internet of Things group identifier and / or sensor data; the base station or UE sends a member inventory command, which includes a service identifier or an ambient Internet of Things group identifier, and a task identifier or an inventory value identifier; if the ambient Internet of Things determines that the inventory has been done before, it ignores the inventory; or, if it determines that the inventory has not been done before, it performs backscatter transmission to the base station or UE, and the backscatter transmission includes the ambient Internet of Things group identifier and / or sensor data.

[0454] In some embodiments, any information carried by the above-mentioned network side, such as task identification, member inventory purpose, inventory value identification, information of target members to be inventoried and / or missed inventory indication information can be carried in the MAC header or MAC payload or MAC CE.

[0455] Optionally, the member inventory command sent by the network side can be the first signal in the previous embodiment; the environmental Internet of Things group identifier can be the device group identifier in the previous embodiment; the missing disk inventory indication information can be the first indication information in the previous embodiment; and the information of the target member to be inventoried can be the second indication information in the previous embodiment.

[0456] Step S6103: Based on the network-side auxiliary information, determine whether to participate in the inventory - based on time.

[0457] Method 1: After completing the first inventory, the Environmental IoT records the elapsed time. If the Environmental IoT loses power, the elapsed time is stored and continues to be recorded when power is restored. If the elapsed time does not exceed the threshold, the repeated inventory is ignored; otherwise, the inventory is performed. The threshold is determined by network configuration or protocol agreement.

[0458] Method 2: The network side will indicate the time information of the current inventory and the time information of the previous inventory. The environmental Internet of Things will record this time information after completing an inventory.
