[0066] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the scope of this disclosure.

[0067] In this disclosure, unless otherwise stated, elements expressed in the singular form, such as "a," "an," "the," "the aforementioned," "this," etc., can mean "one and only one," or "one or more," "at least one," etc. For example, when using articles such as "a," "an," "the," etc. in translation, the noun following the article can be understood as either a singular or a plural expression.

The description of the descriptive objects is found in the claims or the context of the embodiments, and the use of prefixes should not constitute unnecessary restrictions. For example, if the descriptive object is a "field," the ordinal numbers preceding "field" in "first field" and "second field" do not restrict the position or order of the "fields." "First" and "second" do not restrict whether the "fields" they modify are in the same message, nor do they restrict the order of "first field" and "second field." Similarly, if the descriptive object is a "level," the ordinal numbers preceding "level" in "first level" and "second level" do not restrict the priority between "levels." Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different.

[0081] In some embodiments, access network devices, core network devices, or network devices can be replaced by terminals. For example, embodiments of this disclosure can also be applied to structures where communication between access network devices, core network devices, or network devices and terminals is replaced by communication between multiple terminals (e.g., device-to-device (D2D), vehicle-to-everything (V2X), etc.). In this case, the structure can also be configured such that the terminal has all or part of the functions of the access network device.

[0086] IoT-related technologies include MTC (Machine Type Communications), NB-IoT (Narrow Band IoT), and RedCap (Reduced Capability UE). MTC and NB-IoT significantly reduce the cost of IoT terminals by employing technologies such as low bandwidth, single antenna, reduced peak data rate, half-duplex operation, and reduced transmit power. eDRX (enhanced Discontinuous Reception) and PSM (Power Saving Mode) greatly reduce the power consumption of IoT terminals. Simultaneously, MTC and NB-IoT can support a large number of IoT terminals accessing the network, thus meeting the demand for massive connectivity. NB-IoT is a low-power wide-area network technology with key characteristics such as low cost, low power consumption, strong coverage, and massive connectivity. It is largely based on the non-backward-compatible E-UTRA, with a coverage target of MCL of 164dB, greatly enhancing indoor coverage and supporting a large number of low-throughput, low-latency-sensitive devices. NB-IoT supports three operating modes: in-band, standalone, and guardband. Both uplink and downlink RF bandwidths are 180kHz. Downlink uses OFDMA technology with a 15kHz subcarrier spacing, while uplink uses SC-FDMA technology. It supports both single-tone and multi-tone transmission. Enhanced versions of NB-IoT support a wealth of features, including multi-carrier support, positioning, multicast, wake-up signals, and fast small data transmission, and can coexist with LTE and NR systems.

[0087] eMTC is an enhanced version of LTE-M (LTE-Machine-to-Machine), an IoT technology evolved from LTE. It is also a low-cost, low-power wide-area network technology. Compared to NB-IoT, eMTC has slightly weaker coverage, targeting an MCL of 156dB, but it can support higher transmission rates, some mobility, and voice services. eMTC has 1.4MHz uplink and downlink RF bandwidth and can support a maximum peak rate of 1Mbps.

[0088] RedCap, short for Reduced Capability, is a new technology standard based on 5G NR. Simply put, RedCap is a lightweight version of 5G. The large-scale industrial wireless sensor network (IWSN) use cases described by 5G requirements include not only the very demanding URLLC services, but also relatively low-end applications requiring small device size, support for fully wireless transmission, and battery life of several years. These applications have higher requirements than LPWA (i.e., LTE-M / NB-IoT), but lower than URLCC and eMBB. Furthermore, smart city surveillance cameras and wearable device use cases such as smartwatches, electronic health-related devices, and medical monitoring equipment also have the characteristics of small device size, simplified functions, and the need to connect to the 5G radio access network and core network, urgently requiring the introduction of lower-cost, simplified 5G NR terminals. Therefore, 5G NR introduced the NR RedCap issue in Release 17, and all standardization is expected to be completed by mid-2022.

[0089] A-IoT is a novel Internet of Things (IoT) technology. Compared to traditional IoT technologies, a significant characteristic is the massive number of A-IoT terminals (A-IoT UEs, A-IoT devices, A-IoT Tags) in the network, enabling the inventory and monitoring of large-scale objects. A-IoT terminal devices can also be customized to meet different application needs, making A-IoT technology widely applicable and highly practical. Compared to NB-IoT terminals, A-IoT terminals have a simpler structure, lower hardware and maintenance costs, and the entire device may or may not include a power supply.

[0090] A-IoT devices can be categorized into Type 1, Type 2a, Type 2b, and Type 2c. Type 1 and 2a devices are passive, while Type 2b is an active device. Type 1 devices operate based on backscatter, exhibiting the lowest complexity and lowest power consumption. Type 2a devices support energy storage and operate based on backscatter; their complexity and power consumption are higher than Type 1 devices, offering some signal amplification while maintaining relatively low power consumption. Type 2b devices operate based on active transmission, possessing both signal amplification and active information transmission capabilities. Furthermore, Type 2c devices possess both active information transmission and backscatter capabilities. These devices can harvest energy from the environment to power normal uplink and downlink transmissions. Environmental energy includes natural energy such as solar, wind, and nuclear power, as well as artificial energy such as electromagnetic waves emitted by artificial devices.

[0091] Currently, two basic topology scenarios are supported. As shown in Figure 1A, Topology 1 involves a direct connection between the A-IoT base station (or reader) and the A-IoT terminal (A-IoT UE, A-IoT device, A-IoT Tag, device). As shown in Figure 1B, Topology 2 involves communication between the A-IoT device and the UE, with the UE acting as an intermediate node sending data to the network side.

[0092] For devices using backscattering for uplink transmission, a continuous wave (CW) energy source (CW node) is required to provide the electromagnetic waves for reflection during backscattering. The CW is typically of constant amplitude. The CW node can be a standalone node or a base station / intermediate node (e.g., a UE) communicating with the device. The frequency of the electromagnetic wave reflected by the device can be exactly the same as the CW frequency or have some offset. The magnitude of the offset depends on the device's hardware characteristics; the offset may be a fixed value, or if the device hardware supports it, it may support multiple fixed values, or it may be a dynamically adjustable value.

[0093] Information transmission in A-IoT technology can be referenced from RFID. Currently, RFID information and data include the following types:

[0094] Select: Includes Select and Challenge. The reader / writer can use the Select command to select one or more tags within its coverage area based on the data stored in the tags, and the Challenge command to query the encryption and authentication types of the tags. The reader / writer can then inventory or connect to the selected tags.

[0095] Inventory includes commands such as Query, QueryAdjus, QueryRep, ACK, and NAK. Readers can use these commands to identify tags. An inventory count begins with a Query command and ends with sending another Query command, or sending a Select or Challenge command. Sending a Query command requires association with one of four defined sessions (S0, S1, S2, and S3), and a single session can only support one inventory count. Multiple tags may respond during an inventory count. The reader will detect a single tag response and request the tag's EPC code.

[0096] Access includes commands such as Req_RN, Read, Write, Lock, Kill, Access, BlockWrite, BlockErase, BlockPermalock, Authenticate, ReadBuffer, SecureComm, AuthComm, KeyUpdate, Untraceable, FileOpen, FileList, FilePrivilege, FileSetup, and TagPrivilege. The reader / writer can perform operations on tags such as reading, writing, locking, and deactivating them. It can also perform security-related operations such as authentication, and file-related operations such as opening files stored in the tag. Access operations involve multiple commands, and a single reader / writer may only support access to one tag.

[0097] Based on the above types, as passive devices, devices have weaker capabilities compared to ordinary terminals, resulting in poor blind detection capabilities when receiving information sent by a reader. The payload of R2D information affects the length of time-domain resources. For example, when using OOK modulation, if one bit can be mapped to two OOK symbols, then with a payload size of 10, it needs to be mapped to 20 OOK symbols. For the device, if the length of the received data size is unknown, it needs to blindly detect the possible payload size, which is difficult for the device to implement. Two solutions are available: defining a single information format; or defining multiple information formats and defining format indicators. The aim is to simplify the process of the reader sending information to the device as much as possible.

[0098] Therefore, this disclosure proposes a communication method and device, communication system, communication equipment, and storage medium based on the Internet of Things, which simplifies the way network devices send information to first-type terminal devices by defining control information and data information.

[0099] The method proposed in this disclosure is applicable to various communication systems, including but not limited to 4G, 5G, 5G-advance and subsequent communication technologies (such as 6G).

[0123] Figure 2A is an interactive schematic diagram of a communication method provided in an embodiment of this disclosure. As shown in Figure 2A, this embodiment of the disclosure relates to a communication method that can be executed by a communication system, such as the communication system 100 shown in Figure 1C. The communication system includes a network device and at least one first-type terminal device. The interactive method may include the following steps:

[0124] Step 2101: The network device sends first information to one or more first-type terminal devices.

[0125] In some embodiments, the first information includes at least one of control information and data information.

[0126] In some embodiments, the control information includes at least one of the following: selection information, used to instruct one or more first-type terminal devices; query information, used to query at least one of the following information of one or more first-type terminal devices: encryption type, authentication type, battery level, supported information reporting type, device type, identification information, and pre-stored access information; inventory information, used to trigger inventory start or inventory end, or used to indicate at least one of the following: inventory cycle, inventory time length, and inventory round number; feedback information, used to indicate whether the information sent by one or more first-type terminal devices to the network device has been successfully received by the network device; read information, used to trigger a read operation, the read operation including at least one of the following: reading pre-stored information in a preset area of ​​one or more first-type terminal devices, and reading result information after one or more first-type terminal devices perform a preset action; write information, used to trigger a write operation, the write operation indicating at least one of the following: a preset area where the information to be written is written, and the information to be written; lock information, used to lock one or more functions of one or more first-type terminal devices; and deactivation information, used to instruct one or more first-type terminal devices to deactivate.

[0127] In some embodiments, selection information is used by a first type of terminal device to know the terminal device selected by the network device.

[0128] In some embodiments, when selection information is available, the query information is used to query the selected terminal device; when no selection information is available, the query information is used to query all terminal devices that received the first information. In other words, the query information may not include identification information; that is, when the first information includes both selection information and query information, the query information does not include identification information, and the query information is used to query the terminal device indicated by the selection information.

[0129] In some embodiments, selection information can be used simultaneously with pre-stored access information and inventory information.

[0130] For example, the feedback information could be used to indicate to the terminal device whether D2R was successfully received, that is, whether the information sent by the first type of terminal device to the network device was successfully received by the network device.

[0131] For example, reading information can be used to trigger a read operation, which can be reading pre-stored information in a specified area of ​​the device, or reading the result information after the device performs a certain action.

[0132] In some embodiments, the purpose of the written information is not limited. For example, if the device needs to process data, then the reader needs to send the content of the processed data to the device, and the written information may be written data information; or, if the reader needs to instruct the device to perform a certain operation periodically, then the written information may be written control information.

[0133] In some embodiments, the deactivation information may be an instruction for the first type of terminal device to hibernate / deactivate, or the deactivation information may be to disable the first type of terminal device.

[0134] In some embodiments, the data information includes at least one of the following: data information stored in one or more first-type terminal devices in a first storage mode; data information stored in one or more first-type terminal devices in a second storage mode; information to be written corresponding to a write operation; data information requested by one or more first-type terminal devices from a network device; and data information notified by the network device to one or more first-type terminal devices.

[0135] In some embodiments, the first storage method is to store the data in a cache, which can also be called temporary storage. Data stored temporarily may be lost in the event of a power outage. The second storage method is to store the data in memory, which can also be called permanent storage. Data will not be lost in the event of a power outage.

[0136] For example, a network device sends first information to a first type of terminal device. The first information includes at least one of control information and data information. The control information can be at least one of the following information types: selection information, used to indicate one or more devices; whether the recipient of the first information includes these one or more devices; query information, used to query at least one of the following: the device's encryption and authentication type, the device's battery level, the device's supported information reporting type, the device's type, the device's ID information, and the device's pre-stored access information; disk storage information, triggering the start or end of disk storage, or indicating disk storage-related information, such as period, duration, number of rounds, etc.; feedback information, indicating whether D2R was successfully received; read information, triggering a read operation: reading pre-stored information in a specified area of ​​the device, or reading the result information after the device performs a certain action; write information, triggering a write operation: indicating a specific area to be written, or indicating specific information to be written; lock information, locking one or more functions of the device; and deactivation information, indicating that the device is deactivated.

[0137] For example, the data information can be at least one of the following information types: data information temporarily stored on the device; data information permanently stored on the device; specific information for write operations; data information that the device requests the reader to send; data information that the reader actively notifies the device.

[0138] In some embodiments, the network device may package the information included in the first information so that the first type of terminal device can determine the format of the first information before parsing it when it receives the first information.

[0139] In some embodiments, when the first information only includes data information, packaging the data information in the first information results in a second format, which is used to identify that the first information includes data information; when the first information only includes control information, packaging the control information in the first information results in a first format, which is used to identify that the first information includes control information.

[0140] In some embodiments, when the first information includes control information and data information, the information in the first information is packaged, and the format of the first information is the third format. The third format is used to identify that the first information includes data information and control information.

[0141] In some embodiments, the first information satisfies at least one of the following: first information with the same format and occupying the same time-domain resource length; first information with the same format and the same frequency-domain resource and / or modulation scheme configuration, occupying the same time-domain resource length; first information with the same format and the same payload size; first information with the same format and the same encoding scheme; first information with the same format and the same frequency-domain resource configuration; first information with the same format and the same packet header; first information with the same format and the same preamble; first information with the same format and the same information type.

[0142] In some embodiments, when the first information is packaged into a first format, the first information satisfies at least one of the following: first information with the same first format occupies the same time-domain resource length; first information with the same first format and the same frequency-domain resource and / or modulation scheme configuration occupies the same time-domain resource length; first information with the same first format has the same payload size; first information with the same first format has the same encoding scheme; first information with the same first format has the same frequency-domain resource configuration; first information with the same first format has the same packet header; first information with the same first format has the same preamble; first information with the same first format has the same information type.

[0143] In some embodiments, when the first information is packaged into a second format, the first information satisfies at least one of the following: first information with the same second format occupies the same time-domain resource length; first information with the same second format and the same frequency-domain resource and / or modulation scheme configuration occupies the same time-domain resource length; first information with the same second format has the same payload size; first information with the same second format has the same encoding scheme; first information with the same second format has the same frequency-domain resource configuration; first information with the same second format has the same packet header; first information with the same second format has the same preamble; first information with the same second format has the same information type.

[0144] In some embodiments, when the first information is packaged into a third format, the first information satisfies at least one of the following: first information with the same third format occupies the same time-domain resource length; first information with the same third format and the same frequency-domain resource and / or modulation scheme configuration occupies the same time-domain resource length; first information with the same third format has the same payload size; first information with the same third format has the same encoding scheme; first information with the same third format has the same frequency-domain resource configuration; first information with the same third format has the same packet header; first information with the same third format has the same preamble; first information with the same third format has the same information type.

[0145] Step 2102: The first type of terminal device determines the format of the first information.

[0146] In some embodiments, one or more first-type terminal devices may determine the format of the first information based on the received data packet of the first information before parsing the data packet.

[0147] In some embodiments, after receiving the first information, the first type of terminal device determines the format of the first information by the format of the packaged data packet.

[0148] In some embodiments, if the data packet of the first information received by the first type of terminal device is in the format of a first format, then it is determined that the first information includes control information.

[0149] In some embodiments, if the data packet of the first information received by the first type of terminal device is in the second format, then it is determined that the first information includes data information.

[0150] In some embodiments, if the format of the data received by the first type of terminal device as the first information is a third format, then the first information is determined to include control information and data information.

[0151] In some embodiments, the first information satisfies at least one of the following: first information with the same format and occupying the same time-domain resource length; first information with the same format and the same frequency-domain resource and / or modulation scheme configuration, occupying the same time-domain resource length; first information with the same format and the same payload size; first information with the same format and the same encoding scheme; first information with the same format and the same frequency-domain resource configuration; first information with the same format and the same packet header; first information with the same format and the same preamble; first information with the same format and the same information type.

[0152] For example, the first information is divided into at least one information format, including at least one of data information and control information, and the information format is characterized by at least one of the following: the first information of the same information format occupies the same length of time domain resources; the first information of the same information format occupies the same length of time domain resources when the frequency domain resources and / or modulation scheme configurations are the same; the first information of the same information format has the same payload size; the first information of the same information format has the same encoding scheme; the first information of the same information format has the same frequency domain resource configuration; the first information of the same information format has the same packet header; the first information of the same information format has the same preamble; the first information of the same information format has the same information type.

[0153] In some embodiments, the first type of terminal device determines the format of the first information as a first format, that is, the first information includes control information, and the control information enables the first type of terminal device to perform a preset behavior.

[0154] For example, the first information is divided into at least one control information format. This control information format is used solely to carry control information and enables the device to perform a certain action. The control information format is characterized by at least one of the following: first information of the same control information format occupies the same length of time-domain resources; first information of the same control information format occupies the same length of time-domain resources when configured with the same frequency-domain resources and / or modulation scheme; first information of the same control information format has the same payload size; first information of the same control information format has the same encoding scheme; first information of the same control information format has the same frequency-domain resource configuration; first information of the same control information format has the same packet header; first information of the same control information format has the same preamble; and first information of the same control data information format has the same control information.

[0155] For example, the protocol predefines first control information and second control information. The effective payload of the first control information is 10 bits, and the effective payload of the second control information is 20 bits. Since both the first and second control information belong to the same first information format, the payload size for this format is uniformly defined as 25 bits, with any insufficient bits padded with 0s. For the first control information, the effective payload is 10 bits, padded with 0s for a total of 20 bits. For the second control information, the effective payload is 20 bits, padded with 0s for a total of 10 bits.

[0156] In some embodiments, the first type of terminal device determines that the format of the first information is a second format, that is, the first information includes data information, and the first type of terminal device can perform at least one of the following operations on the data information: temporary storage, permanent storage, or ignoring.

[0157] For example, the first information is divided into at least one data information format. This data information format is only used to carry data information, and the device can temporarily store, permanently store, or ignore the data information. The data information format is characterized by at least one of the following: first information in the same control data information format occupies the same length of time-domain resources; first information in the same control data information format occupies the same length of time-domain resources when configured with the same frequency-domain resources and / or modulation scheme; first information in the same control data information format has the same payload size; first information in the same control data information format has the same encoding scheme; first information in the same control data information format has the same frequency-domain resource configuration; first information in the same control data information format has the same packet header; first information in the same control data information format has the same preamble; and first information in the same control data information format has the same data.

[0158] The communication method involved in the embodiments of this disclosure may include steps 2101 to 2102.

[0159] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0160] In the above embodiments, the network device sends the first information to one or more first-type terminal devices by packaging the first information into an information format, so that the first-type terminal devices can determine the format of the first information based on the data packet and determine how to understand the information in the first information.

[0161] Figure 2B is an interactive schematic diagram of a communication method provided in an embodiment of this disclosure. As shown in Figure 2B, this embodiment of the disclosure relates to a communication method that can be executed by a communication system, such as the communication system 100 shown in Figure 1C. The communication system includes a network device and at least one first-type terminal device. The interactive method may include the following steps:

[0162] Step 2201: The network device determines the second information.

[0163] In some embodiments, the network device determines second information based on a protocol predefined method. The second information is used to indicate the format of the first information.

[0164] For example, the network device predefines second information based on the protocol, and the second information is used to indicate the information format of the first information.

[0165] For example, the protocol predefines information format 1 and information format 2. The second information contains 1 bit, where 0 represents information format 1 and 1 represents information format 2.

[0166] In some embodiments, the second information includes at least one of the following: a first format for identifying that the first information includes control information; a second format for identifying that the first information includes data information; and a third format for identifying that the first information includes both control information and data information.

[0167] In some embodiments, the first information includes only control information, and the second information is used to indicate the format of the control information, which enables one or more first-type terminal devices to perform preset behaviors.

[0168] In some embodiments, the first information includes only data information, the second information is used to indicate the format of the data information, and one or more first-type terminal devices are capable of performing at least one of the following operations on the data information: temporary storage, permanent storage, or ignoring.

[0169] For example, the protocol predefines a second piece of information, which is used to indicate whether the first information is in data information format or control information format. For instance, the second information contains 1 bit, where 0 represents data information format and 1 represents control information format.

[0170] For example, the protocol predefines a second piece of information, which is used to indicate the data format of the first piece of information. The protocol predefines data format 1 and data format 2. The second piece of information contains 1 bit, where 0 represents data format 1 and 1 represents data format 2.

[0171] For example, the protocol predefines a second piece of information, which is used to indicate the control information format of the first piece of information. The protocol predefines control information format 1 and control information format 2. The second piece of information contains 1 bit, where 0 represents control information format 1 and 1 represents control information format 2.

[0172] Step 2202: The network device sends first information to one or more first-type terminal devices.

[0173] In some embodiments, the first information includes at least one of control information and data information.

[0174] In some embodiments, the control information includes at least one of the following: selection information, used to instruct one or more first-type terminal devices; query information, used to query at least one of the following information of one or more first-type terminal devices: encryption type, authentication type, battery level, supported information reporting type, device type, identification information, and pre-stored access information; inventory information, used to trigger inventory start or inventory end, or used to indicate at least one of the following: inventory cycle, inventory time length, and inventory round number; feedback information, used to indicate whether the information sent by one or more first-type terminal devices to the network device has been successfully received by the network device; read information, used to trigger a read operation, the read operation including at least one of the following: reading pre-stored information in a preset area of ​​one or more first-type terminal devices, and reading result information after one or more first-type terminal devices perform a preset action; write information, used to trigger a write operation, the write operation indicating at least one of the following: a preset area where the information to be written is written, and the information to be written; lock information, used to lock one or more functions of one or more first-type terminal devices; and deactivation information, used to instruct one or more first-type terminal devices to deactivate.

[0175] In some embodiments, selection information is used by a first type of terminal device to know the terminal device selected by the network device.

[0176] In some embodiments, when selection information is available, the query information is used to query the selected terminal device; when no selection information is available, the query information is used to query all terminal devices that received the first information. In other words, the query information may not include identification information; that is, when the first information includes both selection information and query information, the query information does not include identification information, and the query information is used to query the terminal device indicated by the selection information.

[0177] In some embodiments, selection information can be used simultaneously with pre-stored access information and inventory information.

[0178] For example, the feedback information could be used to indicate to the terminal device whether D2R was successfully received, that is, whether the information sent by the first type of terminal device to the network device was successfully received by the network device.

[0179] For example, reading information can be used to trigger a read operation, which can be reading pre-stored information in a specified area of ​​the device, or reading the result information after the device performs a certain action.

[0180] In some embodiments, the purpose of the written information is not limited. For example, if the device needs to process data, then the reader needs to send the content of the processed data to the device, and the written information may be written data information; or, if the reader needs to instruct the device to perform a certain operation periodically, then the written information may be written control information.

[0181] In some embodiments, the deactivation information may be an instruction for the first type of terminal device to hibernate / deactivate, or the deactivation information may be to disable the first type of terminal device.

[0182] In some embodiments, the data information includes at least one of the following: data information stored in one or more first-type terminal devices in a first storage mode; data information stored in one or more first-type terminal devices in a second storage mode; information to be written corresponding to a write operation; data information requested by one or more first-type terminal devices from a network device; and data information notified by the network device to one or more first-type terminal devices.

[0183] In some embodiments, the first storage method is to store the data in a cache, which can also be called temporary storage. Data stored temporarily may be lost in the event of a power outage. The second storage method is to store the data in memory, which can also be called permanent storage. Data will not be lost in the event of a power outage.

[0184] For example, a network device sends first information to a first type of terminal device. The first information includes at least one of control information and data information. The control information can be at least one of the following information types: selection information, used to indicate one or more devices; whether the recipient of the first information includes these one or more devices; query information, used to query at least one of the following: the device's encryption and authentication type, the device's battery level, the device's supported information reporting type, the device's type, the device's ID information, and the device's pre-stored access information; disk storage information, triggering the start or end of disk storage, or indicating disk storage-related information, such as period, duration, number of rounds, etc.; feedback information, indicating whether D2R was successfully received; read information, triggering a read operation: reading pre-stored information in a specified area of ​​the device, or reading the result information after the device performs a certain action; write information, triggering a write operation: indicating a specific area to be written, or indicating specific information to be written; lock information, locking one or more functions of the device; and deactivation information, indicating that the device is deactivated.

[0185] For example, the data information can be at least one of the following information types: data information temporarily stored on the device; data information permanently stored on the device; specific information for write operations; data information that the device requests the reader to send; data information that the reader actively notifies the device.

[0186] In some embodiments, the first information satisfies at least one of the following: first information having the same second information occupies the same time-domain resource length; first information having the same second information and the same frequency-domain resource and / or modulation scheme configuration occupies the same time-domain resource length; first information having the same second information has the same payload size; first information having the same second information has the same encoding scheme; first information having the same second information has the same frequency-domain resource configuration; first information having the same second information has the same packet header; first information having the same second information has the same preamble; first information having the same second information has the same information type.

[0187] In some embodiments, when the second information is in a first format, the first information satisfies at least one of the following: first information with the same first format occupies the same time-domain resource length; first information with the same first format and the same frequency-domain resource and / or modulation scheme configuration occupies the same time-domain resource length; first information with the same first format has the same payload size; first information with the same first format has the same encoding scheme; first information with the same first format has the same frequency-domain resource configuration; first information with the same first format has the same packet header; first information with the same first format has the same preamble; first information with the same first format has the same information type.

[0188] In some embodiments, when the second information is in a second format, the first information satisfies at least one of the following: first information with the same second format occupies the same time-domain resource length; first information with the same second format and the same frequency-domain resource and / or modulation scheme configuration occupies the same time-domain resource length; first information with the same second format has the same payload size; first information with the same second format has the same encoding scheme; first information with the same second format has the same frequency-domain resource configuration; first information with the same second format has the same packet header; first information with the same second format has the same preamble; first information with the same second format has the same information type.

[0189] In some embodiments, when the second information is in a third format, the first information satisfies at least one of the following: first information with the same third format occupies the same time-domain resource length; first information with the same third format and the same frequency-domain resource and / or modulation scheme configuration occupies the same time-domain resource length; first information with the same third format has the same payload size; first information with the same third format has the same encoding scheme; first information with the same third format has the same frequency-domain resource configuration; first information with the same third format has the same packet header; first information with the same third format has the same preamble; first information with the same third format has the same information type.

[0190] Step 2203: The network device sends second information to one or more first-type terminal devices.

[0191] In some embodiments, the second information is carried by any of the following: a preamble; a synchronization signal; or a preset channel.

[0192] For example, the second information may be carried by a preamble, or by a synchronization signal, or by a new channel.

[0193] In some embodiments, step 2203 is optional, meaning that the network device may send the second information to one or more first-type terminal devices, or it may not send it.

[0194] Step 2204: The A-IoT terminal device determines the format of the first information.

[0195] In some embodiments, the first type of terminal device may determine the format of the first information in the following three ways:

[0196] Method 1: The first type of terminal device determines the second information through blind detection.

[0197] In some embodiments, the first type of terminal device determines the second information as a first format, a second format, or a third format through blind detection.

[0198] In some embodiments, a first format is used to identify that the first information includes control information; a second format is used to identify that the first information includes data information; and a third format is used to identify that the first information includes both control information and data information.

[0199] In some embodiments, the first type of terminal device first decodes the first information according to an information format. If the decoding is successful, the information format is the second information. If the decoding fails, the first information is decoded using a second information format until the decoding is successful, and then the second information is obtained, which is the format of the first information.

[0200] For example, when blindly checking the first information, the device first decodes the first information according to a certain information format. After decoding, it determines the format of the first information and how to understand the information included in the first information based on the decoded information format.

[0201] Method 2: The first type of terminal device determines the second information based on the predefined protocol, that is, determines the format of the first information.

[0202] In some embodiments, the first type of terminal device determines the format of the first information as a first format, a second format, or a third format based on a protocol predefined.

[0203] In some embodiments, a first format is used to identify that the first information includes control information; a second format is used to identify that the first information includes data information; and a third format is used to identify that the first information includes both control information and data information.

[0204] For example, if the device does not receive the second message sent by the reader, the device defaults to the first message format, which is determined by the protocol predefined.

[0205] For example, if the device does not receive the second message sent by the reader, the device defaults to the first message format, which is predefined by the protocol and can be either a control message format or a data message format.

[0206] For example, if the device does not receive the second message sent by the reader, the device defaults to the first message being the first data information format, which is confirmed by the protocol predefined.

[0207] For example, if the device does not receive the second message sent by the reader, the device defaults to the first message being the first control information format, which is confirmed by the protocol predefined.

[0208] Method 3: The first type of terminal device determines the format of the first information based on the received second information.

[0209] In some embodiments, the first type of terminal device determines the format of the first information as a first format, a second format, or a third format based on the second information sent by the network device.

[0210] In some embodiments, a first format is used to identify that the first information includes control information; a second format is used to identify that the first information includes data information; and a third format is used to identify that the first information includes both control information and data information.

[0211] In some embodiments, the first type of terminal device can determine the format of the first information and parse the first information based on the second information determined by the above three methods.

[0212] In some embodiments, the second information is in a first format, that is, the second information is used to indicate the format of the control information, then the first information only includes control information, and the control information enables one or more first-type terminal devices to perform preset behaviors.

[0213] In some embodiments, the second information is a second format, that is, the second information is used to indicate the format of the data information, then the first information only includes the data information, and one or more first type terminal devices can perform at least one of the following operations on the data information: temporary storage, permanent storage, or ignoring.

[0215] In some embodiments, steps 2201 and 2203 are optional and can be omitted or replaced in different embodiments.

[0216] In some embodiments, the execution order of steps 2202 and 2203 is not limited. In embodiments where both steps are included, the execution order of the two steps is not restricted.

[0261] The following are specific solutions provided by embodiments of this disclosure:

[0262] Example 1:

[0263] IoT network devices send first information to IoT terminal devices, the first information including at least one of control information and data information.

[0264] Control information can be at least one of the following information types:

[0265] Selection information, used to indicate one or more devices; query information, used to query at least one of the following: device encryption and authentication type, device battery level, device supported information reporting type, device type, device ID information, and device pre-stored access information; disk storage information, triggering disk storage start or end, or indicating disk storage related information, such as period, time length, number of rounds, etc.; feedback information, indicating whether D2R was successfully received; read information, triggering a read operation, or reading pre-stored information in a specified area of ​​the device, or reading the result information after the device performs a certain action; write information, triggering a write operation: indicating a specific area to be written, or indicating specific information to be written; lock information, locking one or more functions of the device; deactivation information, indicating deactivation of the device.

[0266] The data information includes at least one of the following information types:

[0267] Data temporarily stored on the device; data permanently stored on the device; specific information for write operations; data sent by the device to the reader; data actively notified to the device by the reader.

[0268] Based on the above, the method for determining the information format corresponding to the first piece of information includes at least one of the following:

[0269] Method 1:

[0270] The first information is divided into at least one information format, including at least one of data information and control information. The information format is characterized by at least one of the following:

[0271] The first piece of information with the same information format occupies the same length of time domain resources.

[0272] The first information with the same information format occupies the same length of time domain resources, depending on the configuration of frequency domain resources and / or modulation scheme.

[0273] The first information with the same information format has the same payload size;

[0274] The first piece of information with the same format has the same encoding method;

[0275] First information with the same information format has the same frequency domain resource configuration;

[0276] The first message with the same information format has the same header;

[0277] The first information in the same information format has the same preamble;

[0278] First pieces of information with the same format have the same information type.

[0279] Method 2:

[0280] The first information is divided into at least one control information format. The control information format is used only to carry control information, and the control information format enables the device to perform a certain behavior. The control format is characterized by at least one of the following:

[0281] The first information with the same control information format occupies the same length of time domain resources.

[0282] The first information with the same control information format occupies the same length of time domain resources when the same time domain and / or frequency domain resources and / or modulation scheme are configured.

[0283] The first information with the same control information format has the same payload size;

[0284] The first information with the same control information format has the same encoding method;

[0285] The first information with the same control information format has the same frequency domain resource configuration;

[0286] The first information in the same control information format has the same header;

[0287] The first information in the same control information format has the same preamble;

[0288] The first piece of information with the same control data format has the same control information.

[0289] For example, the protocol predefines first control information and second control information. The effective payload of the first control information is 10 bits, and the effective payload of the second control information is 20 bits. Both the first and second control information belong to the same first information format, so the payload size of this format is uniformly defined as 25 bits, with any insufficient bits padded with zeros. For the first control information, the effective payload is 10 bits, padded with zeros for a total of 20 bits. For the second control information, the effective payload is 20 bits, padded with zeros for a total of 10 bits.

[0290] Method 3:

[0291] The first information is divided into at least one data information format. This data information format is used only to carry data information, and the device may temporarily store, permanently store, or ignore the data information. The data information format is characterized by at least one of the following:

[0292] The first piece of information with the same control data format occupies the same length of time domain resources;

[0293] The first information with the same control data information format occupies the same length of time domain resources when the same time domain and / or frequency domain resources and / or modulation scheme are configured.

[0294] The first piece of information with the same control data format has the same payload size;

[0295] The first information in the same control data information format has the same encoding method;

[0296] The first information has the same control data information format and the same frequency domain resource configuration;

[0297] The first information in the same control data information format has the same header;

[0298] The first information in the same control data information format has the same preamble;

[0299] The first piece of information with the same control data format has the same data.

[0300] Optionally, alternative implementations of Embodiment 1 can be found in the alternative implementations shown in the embodiment of Figure 2A.

[0301] Example 2:

[0302] The method for determining the information format of the first information includes at least one of the following:

[0303] Method 1:

[0304] The protocol predefines a second piece of information, which is used to indicate the information format of the first piece of information.

[0305] For example, the protocol predefines information format 1 and information format 2. The second information contains 1 bit, where 0 represents information format 1 and 1 represents information format 2.

[0306] Furthermore, if the device does not receive the second message sent by the reader, the device defaults to the first message format, which is confirmed by the protocol predefined.

[0307] Furthermore, the second information can be carried by a preamble, or by a synchronization signal, or by a new channel.

[0308] Method 2:

[0309] The protocol predefines a second piece of information, which is used to indicate whether the first piece of information is in a data information format or a control information format.

[0310] For example, the second information contains 1 bit, where 0 represents data information format and 1 represents control information format.

[0311] Furthermore, if the device does not receive the second message sent by the reader, the device defaults to the first message format, which is predefined and confirmed by the protocol and is either a control message format or a control information format.

[0312] Furthermore, the second information can be carried by a preamble, or by a synchronization signal, or by a new channel.

[0313] Method 3:

[0314] The protocol predefines a second piece of information, which is used to indicate the data information format of the first piece of information.

[0315] For example, the protocol predefines data information format 1 and data information format 2. The first information contains 1 bit, where 0 represents information format 1 and 1 represents information format 2.

[0316] Furthermore, if the device does not receive the second message sent by the reader, the device defaults to the first message being the first data information format, which is predefined and confirmed by the protocol.

[0317] Furthermore, the second information can be carried by a preamble, or by a synchronization signal, or by a new channel.

[0318] Method 4:

[0319] The protocol predefines a second piece of information, which is used to indicate the control information format of the first piece of information.

[0320] For example, the protocol predefines control information format 1 and control information format 2. The first information contains 1 bit, where 0 represents information format 1 and 1 represents information format 2.

[0321] Furthermore, if the device does not receive the second information sent by the reader, the device defaults to the first information being the first control information format, which is confirmed by the protocol predefined.

[0322] Furthermore, the second information can be carried by a preamble, or by a synchronization signal, or by a new channel.

[0323] Alternatively, the optional implementation of Embodiment 2 can be found in the optional implementation of the embodiment shown in Figure 2B.

[0324] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0325] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0326] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0327] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
