[0072] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0073] Figure 1 This is a schematic diagram illustrating an application scenario of a state transition indication method provided in an embodiment of this application. For example... Figure 1 As shown, in this scenario, there is an IoT device 100 and a target device 200. The IoT device 100 can transmit data with the target device 200 via a network. The IoT device can be a passive IoT device, such as a passive IoT device (zero-power terminal AIoT).

The target device 200 can send indication information to the IoT device 100, and the IoT device 100 can receive the indication information and switch between an available state and an unavailable state based on the information carried in the indication information; the switch can be from an available state to an unavailable state, or vice versa.

[0074] In traditional technologies, 3GPP defines the form of Ambient IoT terminal devices, which have limited energy storage capacity. In Ambient IoT systems, passive IoT devices can rely on energy from the environment for energy harvesting and data transmission. However, with the rapid development of wireless communication technology, IoT has broad application prospects in areas such as environmental monitoring, intelligent office systems, target monitoring, and traffic flow monitoring. Therefore, higher standards are required for transmission efficiency and scheduling strategies in wireless communication networks.

[0075] In the Ambient IoT system of 3GPP Release 19, passive IoT devices can rely on radio frequency carrier signals (CW) provided by other devices to achieve energy harvesting and data transmission. Due to the limited energy of IoT devices, during a single network command issuance, they may enter an unavailable state due to power depletion, requiring hibernation for charging. This may prevent them from receiving certain network-issued indications, or they may repeatedly respond to the same command, resulting in poor information transmission effectiveness during communication. The state transition indication method for passive IoT devices provided in this embodiment can reduce the impact of passive IoT devices entering an unavailable state due to energy harvesting on the communication process. Target devices in the network can issue indications to passive IoT devices based on the type, capabilities, and operating status of the passive IoT devices. The passive IoT devices can then perform state transitions based on the received indications; that is, passive IoT devices can perform state transitions based on synchronization signals issued by network devices for device state transition indication. The target devices on the network side can configure the timing scheduling strategy and function indication strategy of this synchronization signal (indication information) in conjunction with the communication process. The target devices on the network side can be one or more of readers, CW nodes, and other network devices.

[0076] Based on the aforementioned traditional technologies, this application provides a state transition indication method, specifically for passive IoT devices. This method supports passive IoT devices in performing state transition processes based on indication information from a reader or other network device. The reader or other device sends indication information for device state transitions based on network-side communication. This indication information can be a time indication or a synchronization signal. The target device on the network side can flexibly design the functional indication strategy and timing scheduling strategy of this indication information by combining the network-side indication and the state of the IoT device. The passive IoT device can switch between available and unavailable states promptly based on the received indication information. This indication information can assist the passive IoT device in timely waking up the paging signal or command from the monitoring network, thereby reducing the impact of the passive IoT device entering an unavailable state due to energy harvesting on the communication process and improving the energy utilization and robustness of the passive IoT system.

[0086] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0087] In one embodiment, such as Figure 2 As shown, a method for indicating state transitions is provided, which can be applied to... Figure 1 Taking the target device in the example, the explanation includes the following steps:

[0088] Step 202: Send indication information, which is state transition indication information. The state transition indication information is used to assist IoT devices in transitioning between available and unavailable states based on the state transition indication information.

[0089] Specifically, the target device can be a device in a network, which can be the Internet of Things (IoT), such as a passive IoT. The target device in the network can be one or more of a reader, carrier node, and other network devices. The target device can communicate with the IoT device; for example, the target device can send indication information to the IoT device, which can be state transition indication information. In this way, the IoT device can receive the indication information and, based on the state transition indication information, transition between an available state and an unavailable state.

[0090] In one example, an IoT device may currently be in an unavailable state, so that the IoT device can switch to an available state based on the state transition indication information.

[0091] In the aforementioned state transition indication method, indication information is sent. This indication information is a state transition indication information, used to assist IoT devices in transitioning between available and unavailable states based on the state transition indication information. By adopting this method, without modifying the hardware, the process of zero-power terminals transitioning between different states can be indicated through network devices in passive IoT. This enhances the effectiveness of information transmission between network devices and zero-power terminals, strengthens the management and scheduling of zero-power terminals, and enables zero-power terminals to switch between different states in a timely manner, thus increasing the flexibility of state transitions.

[0092] In one exemplary embodiment, the target device is one or more of a reader / writer, a carrier node, or other network devices.

[0093] Specifically, the target device can be a network device in a passive IoT system. This network device can be a reader, a carrier-based CW node, or other network devices in the passive IoT system. In other words, a reader can trigger an indication message, a carrier-based CW node can trigger the indication message, and other network devices in the passive IoT system can also trigger the indication message. The passive IoT device that receives the indication message can switch between an available state and an unavailable state.

[0094] In this embodiment, multiple devices on the network side can trigger indication information, ensuring the stability of passive IoT sending indication information to IoT devices.

[0095] In an exemplary embodiment, the indication information indicates time information via R2D transmission signal. The time information is related to the state transition of the Internet of Things device. The time information is one or more of time-related information and time configuration information. The time-related information is one or more of time point and time length.

[0096] R2D transmission can be a transmission from a passive IoT reader to an AIoT passive IoT device. In other words, the signal sent by the passive IoT reader to the AIoT passive IoT device can be an R2D transmission signal.

[0097] Specifically, the target device can be a passive IoT reader (AIoT Reader). The reader sends indication information to the passive IoT device. This indication information can be an R2D transmission signal, which can be used to indicate time information. This time information is related to the state switching process of the passive IoT device. For example, this time information can be time-related information of the state switching process of the passive IoT device, or it can be time configuration information of the state switching process of the passive IoT device, or it can be both time-related information and time configuration information.

[0098] Optionally, the time-related information associated with the state switching process of the passive IoT device can be a point in time or a duration of time. Correspondingly, after receiving the indication information, the passive IoT device can switch between an available state and an unavailable state based on the indicated point in time or duration of time in the indication information.

[0099] In one example, the time-related information indicated by the instruction could be a point in time, such as the arrival time of the next target signal, and the current state of the passive IoT device could be unavailable. Thus, the passive IoT device can switch from an unavailable state to an available state based on the arrival time of the next target signal indicated by the instruction.

[0100] Optionally, the explicit indication method includes indicating the time remaining until the next Paging or other trigger signal or state transition time through a duty cycle or an indicator containing time information. Implicit indication methods include indicating the state transition time through the period of the state transition indication signal or the appearance of an indicator in the PRDCH.

[0101] In this embodiment, the indication information can be displayed or implicitly indicated by R2D transmission signals, or one or more of time-related information and time configuration information. This indicates information related to the state transition process of the passive IoT device from a time dimension, ensuring the timely state transition of the passive IoT device and improving the effectiveness and reliability of information transmission in the passive IoT system.

[0102] In one exemplary embodiment, the R2D transmission signal is a dedicated target state transition indication signal, which is used to indicate time-related information associated with the state transition of the Internet of Things device.

[0103] Specifically, the R2D transmission signal can be carried by a dedicated target state transition indication signal. That is, when the indication information is an R2D transmission signal, this signal can be a dedicated target state transition indication signal, specifically used to indicate time-related information associated with the state transition of IoT devices. This time-related information can be a point in time, a duration of time, or both.

[0104] In one example, a passive IoT device receives indication information, which may be a dedicated target state transition indication signal. The passive IoT device can then transition between an available state and an unavailable state based on the time-related information indicated by the dedicated target state transition indication signal.

[0105] In this embodiment, the reader can send dedicated state transition indication information to the passive IoT device, ensuring the stability, security, and flexibility of the indication information transmitted by the reader to the passive IoT device, and adapting to the functional requirements of the reader to indicate the state transition of the passive IoT device.

[0106] In one exemplary embodiment, the R2D transmission signal includes control information or a data field, which is used to indicate time-related information associated with state transitions of IoT devices.

[0107] Specifically, the R2D transmission signal may include control information, or it may include a data field. Thus, the reader can send an R2D transmission signal to a passive IoT device. The control information in the R2D transmission signal may carry indication information, which is time-related information used to indicate state transitions of the IoT device. That is, the control information in the transmission signal may be time-related information used to indicate state transitions of the IoT device, or the control information in the transmission signal may be time-related information related to state transitions of the IoT device. This time-related information may be a point in time, a duration of time, or both.

[0108] Optionally, the data field in the R2D transmission signal may be time-related information used to indicate state transitions of the IoT device, or the digital field in the transmission signal may be time-related information related to state transitions of the IoT device; the time-related information may be a point in time, or a length of time, or both a point in time and a length of time.

[0109] Optionally, after receiving the R2D transmission signal, the passive IoT device can parse the control information in the R2D transmission signal to obtain the time-related information indicated by the control information; or, it can parse the data field in the R2D transmission signal to obtain the time-related information indicated by the data field. In this way, the passive IoT device can perform state transitions based on the time-related information.

[0110] In this embodiment, time-related information is transmitted through the data field of the signal. The complete time-related information contained in the data field ensures the integrity of information transmission and allows the device to directly understand the meaning of the information sent by the reader by parsing the data field, without transmitting unnecessary data, thus improving the efficiency of the device in recognizing indication information. By transmitting time-related information through the control information in the signal, the correctness of the indication information transmission can be ensured, information mistransmission can be avoided, and the efficiency of indication information transmission between the reader and the passive IoT device can be improved.

[0111] In one exemplary embodiment, the R2D transmission signal includes control information or a data field, which is used to indicate time configuration information related to the state transition of the Internet of Things device. The R2D transmission signal includes one or more of paging signals, sub-paging signals, and re-paging signals.

[0112] The R2D transmission signal may include one or more of the following: paging signal triggered by the passive IoT side, sub-paging signal, and re-paging signal.

[0113] Specifically, the R2D transmission signal may include control information or data fields. In this way, the reader can send an R2D transmission signal to a passive IoT device. The control information or data fields in the R2D transmission signal may carry indication information, which is time configuration information related to the state transition of the IoT device. That is, the control information / data fields in the transmission signal may be time configuration information related to the state transition of the IoT device, or the control information / data fields in the transmission signal may be time configuration information related to the state transition of the IoT device.

[0114] Optionally, after receiving the R2D transmission signal, the passive IoT device can parse the control information in the R2D transmission signal to obtain the time configuration information indicated by the control information; or, it can parse the data field in the R2D transmission signal to obtain the time configuration information indicated by the data field. In this way, the passive IoT device can perform state transitions based on the time configuration information.

[0115] In this embodiment, by transmitting time configuration information through the data field of the signal or the control information, the flexibility, integrity and reliability of the time configuration information transmission can be guaranteed, further enriching the diversity of the types of instruction information that the reader can send to passive IoT devices.

[0116] In one exemplary embodiment, the specific execution process of the step "sending indication information" may include:

[0117] Instruction information is sent to IoT devices through a target transmission mode, which includes one or more of periodic transmission modes and non-periodic transmission modes.

[0118] Specifically, the target device can periodically send indication information to the IoT device, or it can send indication information to the IoT device non-periodically. The indication information can be the same or different.

[0119] In this embodiment, devices in the passive Internet of Things (IoT) can send instruction information to IoT devices through various transmission modes, which can be applied to scenarios with different transmission needs, improve the matching degree between various scenarios, and make reasonable and effective use of communication resources based on the actual needs of the scenario.

[0120] In an exemplary embodiment, the R2D transmission signal includes a preamble and transmission content; the preamble includes one or more of a signal start position indication portion and a time acquisition portion; the transmission content includes time-related information or time configuration information.

[0121] Specifically, the R2D transmission signal is used to indicate information related to the state transition process of an IoT device. The structure of the R2D transmission signal may include at least a preamble and transmission content. The preamble may include at least start position indication information and a time acquisition portion. The start position indication information may be a start identifier, and the time acquisition portion may be a time acquisition signal. The data carried in the transmission content may be information related to the state transition of the IoT device, such as time-related information or time configuration information. The time-related information may be a time point, a time length, or both.

[0122] In this embodiment, by carrying time-related information or time configuration information in the transmission content of the R2D transmission signal, information related to device state transitions can be explicitly or implicitly indicated to IoT devices, further improving the efficiency of IoT devices in recognizing indication information.

[0123] In one exemplary embodiment, the R2D transmission signal further includes a post-synchronization code; the transmission content further includes the identification information of the command and the identification information of the device corresponding to the R2D transmission signal, the command being the R2D transmission signal corresponding to the transmission content, and the time acquisition part can at least be used to assist IoT devices in time synchronization.

[0124] Specifically, the structure of the R2D transmission signal may also include a postamble; the transmission content of the R2D transmission signal also includes the Paging ID, which is the command identification information, and the command is the R2D transmission signal. The indication information of the command is the identification information / identity identifier of the R2D transmission signal, etc. The transmission content also includes device identification information, which is the identification information of the device corresponding to the R2D transmission signal. The device corresponding to the R2D transmission signal can be the receiving end configured by the target device to send the R2D transmission signal.

[0125] In one example, the target device can send an R2D transmission signal to an IoT device. This R2D transmission signal may include identification information for the R2D transmission signal itself, as well as identification information for the IoT device receiving the R2D transmission signal, configured by the target device. Upon receiving the R2D transmission signal, the IoT device can perform time synchronization based on the time acquisition portion of the preamble in the R2D transmission signal, ensuring time synchronization between the IoT device and the Internet of Things (IoT).

[0126] In this embodiment, by defining the structure of the R2D transmission signal, the standardization of the instruction information is ensured, which facilitates the identification of IoT devices after receiving the R2D transmission signal and improves the information transmission efficiency.

[0127] In one exemplary embodiment, the indication information includes one or more of the following functions:

[0128] Function 1 indicates the state transition of IoT devices. The state transition instructions include one or more of the following: enable wake-up instruction, disable wake-up instruction, and sleep state.

[0129] Specifically, the target device sends an instruction to the IoT device. This instruction may carry a state transition command. The IoT device can receive this instruction and, based on the state transition command carried in the instruction, perform a state transition. This instruction is used to instruct the IoT device to transition from its current state to another state, or to maintain its current state, etc.

[0130] In one example, the state of an IoT device can also include a wake-up state and a sleep state. The state transition instruction can be to enable the wake-up state, and the corresponding IoT device can switch to the wake-up state; the state transition instruction can be to disable the wake-up state, and if the IoT device is currently in the wake-up state, it needs to switch from the enabled wake-up state to the disabled wake-up state, that is, to disable the current wake-up state of the IoT device; the state transition instruction can also be a sleep instruction, and so on.

[0131] Function 2 indicates the time configuration information of IoT devices, which is related to the state transitions of IoT devices.

[0132] Specifically, the target device sends an instruction message to the IoT device. This instruction message is used to indicate time configuration information related to the state transition process of the IoT device. For example, the instruction message may carry time configuration information related to the state transition process of the IoT device.

[0133] Function 3 indicates the time point or remaining time of the next target signal from the IoT device. The target signal includes one or more of the following: paging signal, sub-paging signal, re-paging signal, question and answer signal, and other trigger signals.

[0134] Specifically, the target device sends an instruction to the IoT device. This instruction may carry the time point of the next target signal or the remaining time length. The time point of the next target signal may be the time point when the target device sends the target signal again, and the remaining time length of the next target signal may be the remaining time before the target device sends the target signal again.

[0135] In one example, an IoT device can receive an instruction from a target device and determine the time when the target device will send the next target signal based on the time point or remaining time length of the next target signal carried in the instruction. Based on this time, a state transition can be performed. For example, the IoT device can switch to an available state before this time point.

[0136] Function 4 indicates the time calibration information of IoT devices, which is related to the state transitions of IoT devices.

[0137] Specifically, the target device sends an instruction to the IoT device. This instruction indicates time calibration information related to the IoT device's state transition process. For example, the instruction may carry time calibration information related to the IoT device's state transition process. The IoT device can then perform time calibration based on this time calibration information to ensure time synchronization between the IoT device, the IoT network, and the target device.

[0138] In this embodiment, the target device sends instruction information to the IoT device through various information transmission methods, further enhancing the diversity of information transmission methods.

[0139] In one exemplary embodiment, the time configuration information includes one or more of the following: device monitoring cycle configuration information indicating the duty cycle monitoring mechanism, and configuration information indicating the number and duration of device availability and unavailability states.

[0140] Specifically, Duty-cycle can be referred to as duty cycle. The time configuration information in the indication information may include one or more of the following: device monitoring cycle configuration information, quantity information, and duration configuration information in the duty-cycle monitoring mechanism. The quantity information is the number (times) of the IoT device configured by the target device in the available state, and may also include the number of times the IoT device configured by the target device is in the unavailable state. The duration configuration information may be the duration for which the IoT device configured by the target device can be in the available state, and the duration for which the IoT device can be in the unavailable state.

[0141] Optionally, after receiving the instruction information from the target device, the IoT device can obtain the duration of the IoT device's available state and / or the duration of the IoT device's unavailable state as indicated by the instruction information. For example, the IoT device may currently be in an available state, and the first time it is in an available state can be obtained. If the IoT device determines that the first time exceeds the duration of the available state indicated by the instruction information, the IoT device can switch from the available state to the unavailable state.

[0142] In this embodiment, the time configuration information may include period configuration information, the number of different states, and the duration, which can ensure the accuracy of the indication information sent by the target device to the IoT device and reduce the probability of mistransmission.

[0143] In one exemplary embodiment, the time calibration information includes time slot decrement count indication information.

[0144] Specifically, the time slot countdown indication information sent by the target device to the IoT device can be the actual time slot countdown on the target device side. Thus, after receiving the time slot countdown indication information, the IoT device can calibrate its locally recorded time slot countdown based on the actual time slot countdown on the target device side, obtaining the calibrated time slot countdown on the device side. For example, after receiving the time slot countdown indication information, the IoT device can update its locally recorded time slot countdown based on the actual time slot countdown on the target device side; for instance, it can update its locally recorded time slot countdown to the actual time slot countdown on the target device side.

[0145] In this embodiment, data synchronization between the terminal side and the network side is ensured by calibrating and synchronizing the time slot decrement count between the IoT device and the target device in the IoT.

[0146] In one exemplary embodiment, the specific execution process of the step "sending indication information" may include:

[0147] Indication information is sent through a target timing scheduling mode. This target timing scheduling mode includes one or more of a continuous transmission mode and a non-continuous transmission mode.

[0148] Specifically, the target device can send indication information to the IoT device through the timing scheduling parameters corresponding to the continuous transmission mode; the target device can also send indication information to the IoT device through the timing scheduling parameters corresponding to the non-continuous transmission mode. The indication information can be an R2D transmission signal.

[0149] In this embodiment, indication information is sent through multiple timing scheduling modes to ensure the degree of matching with various scenarios with different needs.

[0150] In one exemplary embodiment, the target timing scheduling mode is a continuous transmission mode, and the method further includes: in a first stage, receiving timing scheduling parameters sent by the core network, the timing scheduling parameters including one or more of start time, end time, and time period. The first stage may be a stage prior to the start of the inventory process.

[0151] Specifically, if the target device sends instruction information to the IoT device through a continuous transmission mode, then in the stage before the inventory process begins, the core network can send the timing scheduling parameters corresponding to the continuous transmission mode to the target device.

[0152] Correspondingly, the specific execution process of the step "send instruction information" may include:

[0153] In the next stage after the first stage, target state transition indication signals are periodically sent to IoT devices based on timing scheduling parameters. These target state transition indication signals indicate the time interval until the next target signal is sent. The next stage after the first stage can be a communication cycle stage within the inventory process.

[0154] Specifically, during the inventory process, the target device can send a dedicated target state transition indication signal to the IoT device based on the timing scheduling parameters received from the core network, that is, according to one or more of the start time, end time and time period included in the timing scheduling parameters.

[0155] For example, during the inventory process, the target device can periodically send a dedicated target state transition indication signal to the IoT device according to the start time indicated by the timing scheduling parameter, after the start time is reached, until the end time indicated in the timing scheduling parameter is reached, at which point the target device stops sending signals to the IoT device.

[0156] In this embodiment, by sending timing scheduling parameters from the core network device to the target device in the Internet of Things (IoT), communication jitter can be avoided, and the core network can control the communication between the IoT and IoT devices.

[0157] In an exemplary embodiment, the target timing scheduling mode is a non-persistent transmission mode, and the specific execution process of the step "sending indication information" may include:

[0158] Based on timing scheduling parameters, a target state transition indication signal is sent to the IoT device. The timing scheduling parameters are triggered by the core network or configured by the target device.

[0159] Specifically, if the target device sends instruction information to the IoT device through a non-persistent transmission mode, the target device can send a target state transition indication signal to the IoT device based on the timing scheduling parameters received from the core network or the timing scheduling parameters configured locally by the target device. The timing scheduling parameters are the parameters corresponding to the non-persistent transmission mode.

[0160] Optionally, the timing configuration parameter can be a time position configured by the reader / writer, or a time interval configured by the reader / writer. In this way, the target device (reader / writer) can send a dedicated target state transition indication signal to the IoT device non-periodically according to the time position; or, the reader / writer can send a dedicated target state transition indication signal to the IoT device periodically according to the time interval configured by the reader / writer. For example, this timing scheduling parameter can be used to indicate that a dedicated target state transition indication signal is sent multiple times at predefined time intervals after a certain period following the last Paging or trigger signal transmission.

[0161] In this embodiment, the specific content of the timing scheduling parameters in the non-continuous transmission mode is defined to ensure the flexibility of timing scheduling, as well as the flexibility and controllability of the reader sending dedicated target state transition indication signals to IoT devices.

[0162] In one exemplary embodiment, the timing scheduling parameters include one or more of the following: start time, end time, transmission period, minimum time between the target state transition indication signal and the next target signal, maximum time between the target state transition indication signal and the next target signal, and minimum time between the target state transition indication signal and the previous target signal.

[0163] Specifically, the start time can be the start time T1 when the target device sends the instruction information to the IoT device, the end time can be the end time T2 when the target device sends the instruction information to the IoT device, and the sending period can be the sending period Tw when the target device sends the instruction information to the IoT device.

[0164] The time between the target state transition indication signal and the next target signal, including the maximum and minimum times, is the minimum time T, which represents the minimum difference between the time when the target device sends the target state transition indication signal and the time when the target device sends the next target signal. W2R_min The maximum time characterizes the maximum time difference T between the time when the target device sends the target state transition indication signal and the time when the target device sends the next target signal. W2R_max The minimum time representation between the target state transition indication signal and the previous target signal; the minimum time T between the time when the target device sends the target state transition indication signal and the time when the target device last sent the target signal. R2W_min .

[0165] Correspondingly, the minimum time between the target state transition indication signal and the next target signal is greater than or equal to the time it takes for the IoT device to complete a single state transition; the time interval between adjacent target state transition indication signals is less than the maximum time for a single discharge of the IoT device.

[0166] Specifically, the minimum time T between the state transition indication signal and the next Paging is... W2R_min Greater than or equal to the time it takes for the tag (IoT device) to complete one state transition; the time interval T between two adjacent state transition indication signals. W It needs to be less than the maximum time for a single discharge of the tag.

[0167] In this embodiment, the specific content of the timing scheduling parameters is refined to achieve fine control over the process of the reader sending a dedicated target state transition indication signal to the IoT device, thereby improving the effectiveness of information transmission.

[0168] In one exemplary embodiment, the specific execution process of the step "sending indication information" may include:

[0169] Based on the instruction information, time-frequency domain resources are allocated to obtain the allocated time-frequency domain resources; based on the allocated time-frequency domain resources, instruction information is sent to IoT devices.

[0170] The allocated time-frequency domain resources are either independent time-frequency domain resources or time-frequency domain resources that reuse R2D transmission.

[0171] Specifically, the target device can allocate resources based on the process of issuing instruction information, and the allocated resources are used to support the target device in issuing instruction information to IoT devices. Optionally, the IoT can allocate independent time-frequency domain resources, and the target device can issue instruction information to IoT devices based on the allocated independent time-frequency domain resources.

[0172] Optionally, after the target device allocates time-frequency domain resources, the allocated time-frequency domain resources can be those transmitted via R2D. In this way, the target device can reuse the time-frequency domain resources transmitted via R2D to send instruction information to IoT devices.

[0173] In this embodiment, the performance of the communication network can be optimized by the reasonable allocation of time-frequency domain resources, high-speed information transmission can be achieved by transmitting data through independent time-frequency domain resources, and the utilization rate of time-frequency domain resources can be guaranteed by data transmission through reused resources.

[0174] In one exemplary embodiment, the target device is a reader / writer; the specific execution process of the step "sending indication information" may include:

[0175] The indication information is merged into the downlink transmission signal, and the downlink transmission signal is sent to the IoT device.

[0176] Specifically, the reader can combine the indication information with the downlink transmission signal to obtain a downlink transmission signal carrying the indication information, and then send the downlink transmission signal carrying the indication information to the Internet of Things device.

[0177] In this embodiment, the utilization rate of communication resources is improved, the data transmission efficiency is enhanced, and the IoT devices can be flexibly switched between available and unavailable states in a timely manner.

[0178] In one exemplary embodiment, such as Figure 3 As shown, the method also includes:

[0179] Step 302: Determine the type of IoT device / IoT device group corresponding to the target signal and determine the target index.

[0180] Step 304: Based on the pre-configured correspondence between indexes and sending parameters, determine the target sending parameters corresponding to the target index.

[0181] Specifically, the transmission parameters include time-frequency domain resources and timing scheduling parameters. The passive IoT devices in the inventory process can include multiple types of passive IoT devices or multiple groups of passive IoT devices. The reader can be configured with the index of the target state transition signal of each type or group of passive IoT devices, as well as the transmission parameters corresponding to each index, i.e., the correspondence between the index and the transmission parameters.

[0182] In one example, the reader can determine the corresponding target index based on the type of IoT device corresponding to the target signal, or the group of passive IoT devices to which the target signal is targeted. In this way, the reader can determine the target transmission parameters corresponding to the target index based on the pre-configured correspondence between the index and the transmission parameters. The reader can then send the indication information to the IoT device or group of IoT devices corresponding to the target signal according to the time-frequency domain resources and timing schedule indicated by the transmission parameters.

[0183] In this embodiment, by designing different types or groups of passive IoT devices, the Reader can be supported in establishing corresponding time-frequency domain resources and timing scheduling parameters for different types of devices based on the device type or group corresponding to the Paging signal.

[0184] In one exemplary embodiment, the target signal includes one or more of the following: paging signal, sub-paging signal, re-paging signal, question and answer signal, and other triggering signals.

[0185] Specifically, the target signal may include one or more of the following: a triggered paging signal, a sub-paging signal, a re-paging signal, a question-and-answer signal, and other triggering signals.

[0186] In one embodiment, such as Figure 4 As shown, a method for indicating state transitions is provided, which can be applied to... Figure 1 Taking IoT devices as an example, the explanation includes the following steps:

[0187] Step 402: Receive indication information, which is a state transition indication information.

[0188] Step 404: Based on the state transition indication information, transition between the available state and the unavailable state.

[0189] Specifically, the target device can be a device in a network, which can be the Internet of Things (IoT), such as a passive IoT. The target device in the network can be one or more of a reader, carrier node, and other network devices. The target device can communicate with the IoT device; for example, the target device can send indication information to the IoT device, which can be state transition indication information. In this way, the IoT device can receive the indication information and, based on the state transition indication information, transition between an available state and an unavailable state.

[0190] In one example, an IoT device may currently be in an unavailable state, so that the IoT device can switch to an available state based on the state transition indication information.

[0191] In this embodiment, IoT devices can switch states based on received instruction information. Without modifying the hardware, the network devices in the passive IoT can instruct the zero-power terminal to switch between different states, enhancing the effectiveness of information transmission between the network devices and the zero-power terminal, improving the management and scheduling of the zero-power terminal, and enabling the zero-power terminal to switch between different states in a timely manner, thus enhancing the flexibility of state transitions.

[0192] In one embodiment, Figure 5 A signaling interaction flowchart is provided for a method of indicating state transitions. For example... Figure 5 As shown, the target device can be a reader / writer, and the state transition indication information carried by the indication information includes at least time configuration information; the method includes the following steps:

[0193] Step 1: Before the inventory process begins, the network side configures the device state transition time period information and the corresponding Paging command identification ID in the Paging command. Specifically, taking the inventory process as an example, the network side can be a reader in the Internet of Things (IoT). Before the inventory process begins, the reader can configure the identification information ID of the command and the time period information used to issue the command in the Paging command. The command can be the instruction information issued by the reader to the IoT device.

[0194] Step 2: At the start of the inventory process, the Reader sends a Paging message to the device, which includes the message identification ID, the time configuration information of the state transition, the timing information of the sub-Paging or trigger signal access opportunity, and starts the time slot counter.

[0195] Step 3: During the inventory process, the Reader periodically sends a time slot decrement indicator for the next sub-Paging or trigger signal to the device to assist the device in calibrating the time slot count.

[0196] Step 4: After the Reader sends the (next) sub-Paging or trigger signal, reset and restart the slot counter.

[0197] Step 5: Determine whether the sub-Paging or trigger signal has reached the maximum number of times, or whether a termination instruction has been received from the network; if yes, proceed to step 6; otherwise, repeat step 3.

[0198] Step 6: The process of sending the current inventory wheel status indication information ends.

[0199] In one embodiment, Figure 6 A signaling interaction flowchart is provided for a method of indicating state transitions. For example... Figure 6 As shown, the target device can be a reader / writer, which sends indication information to the IoT device through a continuous transmission mode; the indication information carries state transition indication information (signals) that includes at least time-related information, and the method includes the following steps:

[0200] Step 1: Before the inventory process begins, the network side configures the start time, end time, and transmission period T for the Reader to send status transition indication signals. w This includes the corresponding command identification ID. Specifically, taking the inventory process as an example, the network side can be a reader / writer in the Internet of Things (IoT). Before the inventory process begins, the reader / writer can configure the timing parameters for sending state transition indication signals and the identification ID of the state transition indication signal. The timing parameters can include the start time, end time, and transmission cycle for the reader / writer to send the state transition indication signal to the IoT device.

[0201] Step 2: After the startup time arrives, the Reader will start at a time period T. w The system continuously sends state transition indication signals, which include at least the identification ID of the corresponding inventory or paging command, time synchronization information, and an indication of the arrival time of the next paging command. Specifically, after reaching the start time, the reader sends a state transition indication signal to the Internet of Things (IoT), which includes at least the identification information of the indication message and an indication of the arrival time of the next paging command.

[0202] Step 3: Determine whether the end time has been reached, or whether a termination instruction has been received from the network. If yes, proceed to step 4; otherwise, repeat step 2.

[0203] Step 4: The process of sending status indication information for the current inventory round ends, that is, the process of sending status transition indication information in the current inventory round ends.

[0204] In one embodiment, Figure 7A signaling interaction flowchart is provided for a method of indicating state transitions. For example... Figure 7 As shown, the target device can be a reader / writer, which sends indication information to the IoT device through a non-persistent transmission mode; the indication information carries state transition indication information (signals) that includes at least time-related information, and the method includes the following steps:

[0205] Step 1: Before the inventory process begins, the network side configures the Reader to send state transition indication signals, including the start time, activation cycle, and corresponding command identification ID. Specifically, taking the inventory process as an example, the network side can be a reader / writer in the Internet of Things (IoT). Before the inventory process begins, the reader / writer can obtain the timing parameters for sending the state transition indication signal and the identification ID of the state transition indication signal. The timing parameters can include the start time, end time, and transmission cycle for the reader / writer to send the state transition indication signal to the IoT device.

[0206] Step 2: The Reader checks the timer and determines if the start time has been reached; if it has, proceed to Step 3. If not, proceed to Step 9; specifically, the Reader starts the timer and records the time indication until the next Paging command arrives.

[0207] Step 3: Determine if the time until the next paging is less than or equal to T. W2R_min If yes, proceed to step 5; otherwise, proceed to step 4.

[0208] Step 4, the Reader uses the time period T sent from the network side or a predefined time period. W Send a status transition indication signal, which includes at least the corresponding inventory or Paging command identification ID, time synchronization information, and an indication of the arrival time of the next Paging command.

[0209] Step 5: The Reader stops sending state transition indication information and resets the timer; specifically, if the reader determines that the time interval between the state transition indication signal and the next paging is less than or equal to T... W2R_min When this happens, the reader can stop sending the state transition indication signal and reset the timer.

[0210] Step 6: The Reader sends a Paging signal, starts a timer, and records the time until the next Paging command arrives.

[0211] Step 7: Determine if the time since the last paging is greater than or equal to T. R2W_min Alternatively, check if a network-side instruction has been received; if yes, proceed to step 8; otherwise, repeat step 7.

[0212] Step 8, the Reader uses the time period T sent from the network side or a predefined time period. W The system sends a status transition indication signal, which includes at least the corresponding inventory or Paging command identification ID, time synchronization information, and an indication of the arrival time of the next Paging command. Specifically, the Reader periodically sends a status transition indication signal after sending a Paging message for a certain period of time, which includes at least the corresponding inventory or Paging command identification ID, time synchronization information, and an indication of the arrival time of the next Paging command; it supports the following two triggering methods:

[0213] (1) The network side instructs the Reader to send a state transition indication signal at a certain time period;

[0214] (2) The timer has elapsed for time T R2W_min Then, the Reader sends a state transition indication signal at a time period Tw, either from the network side or a predefined time period.

[0215] Step 9: Determine whether the termination time has been reached or whether an instruction has been received from the network side. If yes, proceed to step 10; otherwise, return to step 3 and repeat the process.

[0216] Step 10: The process of sending the status indication information of the current inventory round ends, that is, the process of sending the status transition indication information in the current inventory round ends.

[0217] In one example, such as Figure 8 The diagram shown is a schematic diagram of the signal structure of a state transition indication signal. The state transition indication signal includes a preamble, transmission content, and a post-synchronization code. The preamble includes a start identifier and a time acquisition signal. The transmission content may include corresponding command instructions (i.e., the identification information of the state transition indication signal) and state switching indication information (i.e., the actual indication information used to indicate or assist IoT devices in performing state transitions).

[0218] The state transition indication method provided in this embodiment can indicate state transitions without modifying the hardware structure of the IoT device and the target device. It is relatively easy to implement in passive IoT readers, CW nodes, or network devices. This method is applicable to the 3GPP R19 Ambient IoT scheme. Operator networks can use passive IoT readers, CW nodes, or network devices to indicate the state transitions of zero-power terminals, enhancing the management and scheduling of passive IoT devices within the area. On the network side, the state transition process of passive IoT devices can be indicated through readers or other network devices, strengthening network-side management and control of passive IoT. On the terminal side, the impact of unavailable energy harvesting by passive IoT devices on the communication process can be reduced, improving the energy utilization and robustness of the passive IoT system.

[0219] It should be understood that, although Figure 1-8 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1-8 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.
