[0185] 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).

[0186] 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.

[0187] 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.

[0188] In some embodiments, ambient powered IoT is a promising technology that can address the aforementioned unmet needs. An ambient powered IoT device is an IoT device that is powered by energy harvesting, either without a battery or with limited energy storage capability (e.g., using capacitors), by harvesting radio waves, light, motion, heat, or any other suitable power source.

[0189] 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."

[0190] 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.

[0191] 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 an RF excitation signal, activating a passive node (typically an RFID tag). The tag then uses backscatter communication to modulate its information onto the RF signal. The reader then receives the reflected signal from the passive tag and demodulates it, achieving information transmission.

[0192] 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.

[0193] 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).

[0194] 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.

[0195] In some embodiments, see FIG1c, which shows a network architecture for wireless communication based on backscatter technology to achieve communication between ambient energy devices.

[0196] Architecture 1: Direct downlink (DL) and uplink (UL) data reception and transmission between ambient power IoT devices and base stations.

[0197] 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.

[0198] 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.

[0199] 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.

[0200] In some embodiments, referring again to Figure 1c, two topology scenarios are supported. One is a direct connection between an ambient IoT base station (or reader) and an ambient IoT device (or tag). The other is communication between an ambient IoT device and a user end (UE), with the UE acting as an intermediate node and sending data to the network.

[0201] In some embodiments, the spectrum resources that can be used for Ambient IOT communication (i.e., communication between ambient IOT device and base station (architecture / topology 1) and UE (architecture / topology 2)) can be in the form of in-band, guard-band or stand alone. Among them, in-band uses normal New Radio (NR) communication (for example, downlink (DL, Downlink) / uplink (UL, UpLink) UL communication between base station and other UE (topology 1), DL / UL communication between UE and base station (topology 2)) DL and / or UL spectrum resources. Guard-band uses the spectrum resources of the protection band of normal NR communication DL and / or UL spectrum, and stand alone is a spectrum resource used for spectrum resources unrelated to NR communication.

[0202] In some embodiments, referring to FIG1d , Ambient IoT devices can be divided into three types:

[0203] Device A: No energy storage, no independent signal generation / amplification, i.e. backscatter transmission;

[0204] 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.

[0205] Device C: has energy storage and independent signal generation, i.e., active RF components for transmission.

[0206] In some embodiments, the following constraints are imposed on ambient IoT devices:

[0207] The overall goal should be to develop a harmonized air interface design that minimizes differences in ambient IoT environments (if necessary) to support the following devices:

[0208] Peak power consumption is ~1W, with energy storage capability and an initial sampling frequency offset (SFO) of up to 10X ppm. There is no DL or UL amplification in the device. The UL transmission of the device is backscattered on an externally provided carrier.

[0209] ≤ several hundred W peak power consumption1, with energy storage, initial sampling frequency offset (SFO) up to 10X ppm, and in-device DL and / or UL amplification. The device’s UL transmission can be generated internally or backscattered on an externally provided carrier.

[0210] X will be determined by the working group.

[0211] In some embodiments, in order to support data transmission of A-IoT devices, the network needs to support the following functions: A device in the network can support one or more functions.

[0212] In some embodiments, the function as an energy source (ES) is only used for device type B and type C.

[0213] In some embodiments, the downlink transmission (DT) function sends indication information to the A-IoT device, thereby triggering uplink transmission of the A-IoT device.

[0214] In some embodiments, the continuous wave (CW) excitation function is used only by devices A and B. A-IoT devices achieve uplink transmission by backscattering CW. CW is actually a type of ES, and A-IoT devices can receive CW and store energy.

[0215] In some embodiments, the uplink receiving (UR) function receives uplink information backscattered by the A-IoT device, or receives uplink information actively transmitted by the A-IoT device.

[0216] In some embodiments, the device performing the above-mentioned ES, DT, CW, or UR functions may be a UE, a repeater, a relay, or a base station. A device may support only one of the above-mentioned functions. Alternatively, a device may support multiple of the above-mentioned functions simultaneously. Alternatively, a device may support all of the above-mentioned functions simultaneously.

[0217] In some embodiments, in an RFID communication system, commands are divided into three categories based on their functionality: Select, Inventory, and Access. There are five Inventory commands: Query, QueryAdjust, QueryRep, ACK, and NAK, all of which are mandatory.

[0218] In some embodiments, after a tag receives a valid Query command, each tag selected by the set criteria generates a random number (similar to rolling a dice), and each tag whose random number is zero will generate a response (send back a temporary password RN16 - a 16-bit random number) and transfer to the Reply state; tags that meet other conditions will change certain attributes and flags, thereby exiting the above tag group, which helps to reduce duplicate identification.

[0219] In some embodiments, after receiving a valid QueryAdjust command, each tag generates a new random number (like re-rolling a dice), and the rest is the same as Query.

[0220] In some embodiments, after receiving a valid QueryRep command, the tag only decrements the original random number of each tag in the tag group by one, and the rest is the same as Query.

[0221] In some embodiments, only a single tag can receive a valid ACK command (using the aforementioned RN16, or handle—a 16-bit random number temporarily representing the tag's identity, as a security mechanism!). Upon receipt, it then sends back the contents of the EPC area—the most basic function of the EPC protocol.

[0222] In some embodiments, after receiving a valid NAK command, the tag switches to the Arbitrate state except for the Ready or Killed states where the tag remains in the original state.

[0223] In some embodiments, the Access class commands include five mandatory commands: Req_RN, Read, Write, Kill, and Lock, and three optional commands: Access, BlockWrite, and BlockErase.

[0224] In some embodiments, in the relevant RFID, after the tag receives the Query command from the interrogator, the Query command carries a Q, and the value of Q is (0..15). The tag will generate a random number (0..2Q-1) using the random number generator RNG based on the Q value.

[0225] In some embodiments, each time a QueryRep is received, the random number is reduced by 1 until it reaches 0, and the tag can then perform backscattering to send information to the interrogator (or reader).

[0226] In some embodiments, the identification and access opening operation for a specific tag is completed based on the random number RN16. After obtaining the Electronic Product Code (EPC), the network side identifies a specific tag.

[0227] In some embodiments, before enabling an access command operation for a specific tag, the network side requests a new random value, namely a handle, from the tag. Subsequent communications identify a tag based on the handle.

[0228] In some embodiments, the RFID system of the RFID EPC global Class 1 Generation 2 (EPC C1G2) standard operates in the frequency band of 860-960 MHz. The EPC C1G2 standard is primarily dedicated to providing a unified method for reading data from RFID tags, writing data to tags, and tag communication.

[0229] In some embodiments, the EPC C1G2 protocol standard is a half-duplex protocol, which allows only one reader to send a signal or only one tag to send a signal in one transmission.

[0230] Therefore, the reader and the tag will not send signals at the same time, and different tags also work in series.

[0231] However, in ambient IoT, concurrent communication is important. This means multiple tags can simultaneously perform one-to-one operations with the network, similar to access commands. Therefore, ensuring handle uniqueness is crucial. Furthermore, the RN16 negotiation process in related technologies involves excessive and cumbersome signaling interactions, impacting communication efficiency.

[0265] Exemplarily, the first random number is RN16'.

[0266] In some embodiments, the first random number is used to associate with the second device and to request that the second device access the network. The association of the first random number with the second device can be understood as the first random number uniquely indicating, uniquely binding, or uniquely identifying the second device. For example, when the first random number is A, A can be the identity of the second device or A can be bound to the second device. The understanding of the association between random numbers and devices in this disclosure is similar and is not limited here.

[0267] In some embodiments, the first random number is used to uniquely identify the second device and to request the second device to access a network.

[0268] In some embodiments, the first random number is a unique identifier of the second device during the transmission of the first type of command between the first device and the second device.

[0400] Step S5101: The first device sends first information to the second device.

[0401] In some embodiments, the first information is used to indicate: a first random number configured for the first device, the first random number being used to associate with the second device and to request the second device to access a network.

[0404] In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through two exemplary embodiments:

[0405] Example 1

[0406] Example 1 shows a tag access method for a group of tags.

[0407] In some embodiments, referring to FIG6a , a communication method is provided, the method comprising:

[0408] Step S6101: The tag receives the signaling (corresponding to the third information) sent by the network side (which can be a base station or a UE, that is, a node with reader function); the signaling configures a Q, and the tag generates at least one random value RN16 based on the Q value.

[0409] Step S6102: The tag determines whether it can access the network based on the command received from the network side. If it can access the network, for example, the value of the slot-counter or RN16 is reduced to 0000h, the tag sends RN16 and EPC to the reader.

[0410] Step S6103: The network side sends an ACK to the network side based on the received tag information, and indicates the RN16 that has received the tag and the RN16' that has been configured by the network side (corresponding to the first information).

[0411] Step S6104: After receiving RN16', Tag sends a confirmation message to the network side. The confirmation message includes the RN16' configured by the network side and uses this RN16' as a handle to represent the tag in subsequent signaling interactions.

[0412] Example 2

[0413] Example 2 shows a tag access method for a tag.

[0414] For a tag, the network side requires a tag to access the network side. Instead of using the paging process, the tag is directly requested to access the network side through an inventory command, such as a query, to achieve two-step fast network access.

[0415] In some embodiments, referring to FIG6b , a communication method is provided, the method comprising:

[0416] Step S6201: Receive the signaling (corresponding to the first information) sent by the network side (which can be a base station or a UE, that is, a node with reader function), which includes: RN16 configured on the network side, and EPC (or other unique identification tag id).

[0417] Step S6202: After receiving RN16, the Tag sends a confirmation message to the network side, which includes the RN16 configured by the network side. This RN16 is used as a handle for subsequent signaling interactions to indicate the tag's identity.

[0429] Step S6307: The terminal sends a QueryRep command to the environmental IoT device.

[0430] Step S6308: The slot counter of the environmental IoT device counts.

[0431] Step S6309: The environmental IoT device determines that the time slot counter counts to 0.

[0432] Step S6310: The environmental IoT device sends RN16 and / or EPC to the terminal.

[0433] Step S6311: The terminal sends RN16 and configured RN16' to the environmental IoT device.

[0434] Step S6312: The environmental IoT device sends RN16' to the terminal as a handle.

[0435] Step S6313: The terminal stores EPC and RN16'.

[0436] Step S6314: The environmental IoT device sends RN16 to the terminal.

[0437] Step S6315: The terminal sends a message carrying RN16 to the environmental IoT device.

[0438] Step S6316: The environmental IoT device sends EPC and RN16 to the terminal.

[0439] Step S6317: The terminal sends RN16 and RN16' to the environmental IoT device.

[0440] Step S6318: The environmental IoT device sends information carrying RN16' to the terminal.

[0441] Step S6319: The terminal stores EPC and RN16'.

[0442] In the above steps, S6310 to S6313 and S6314 to S6319 can be executed one by one.
