The term "base station" is not limited to any specific technical terminology. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0046] Core network equipment, also known as core network nodes, core network functions, or core network elements, includes, but is not limited to, at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (or L-NEF), and Binding Support.

[0047] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0048] AIoT, also known as Ambient Power-Enabled Internet of Things (Ambient Power-Enabled IoT), is a type of IoT business where IoT devices are powered through energy harvesting. These devices either do not have batteries or have limited energy storage capacity (e.g., using a capacitor). Energy sources for harvesting include radio waves, light, motion, heat, or other suitable energy sources.

[0049] Low-power IoT devices are a type of IoT device characterized by low overall power consumption, including low-power signal reception and low-power signal transmission. Due to their low overall power consumption, the energy for communication can be derived from the environment, such as wind power, kinetic energy, heat energy, or radio frequency (RF) signals. They can also be referred to as AIoT, passive IoT devices, or response devices.

[0050] IoT devices can transmit signals using backscattered radio frequency (RF) signals; these devices are also called electronic tags or radio frequency identification (RFID) tags. Some active tags have the ability to generate signals actively, but in order to achieve low power consumption, they are generally below 0dBm, for example, less than or equal to -10dBm.

[0051] In some embodiments, AIoT devices can be classified based on factors such as energy source, energy storage capacity, and whether they are passive or active transmitters, and can be categorized into the following device types:

[0052] Device Type A: This is a passive device, which has no energy storage and no independent signal generation / amplification, i.e., backscatter transmission;

[0053] Equipment Type B: Semi-Passive Device, also belonging to the broader category of Passive Devices. It features energy storage but lacks independent signal generation, relying on backscatter transmission. The use of the stored energy can include amplifying the reflected signal.

[0054] Device type C: Active Device, which has energy storage and independent signal generation, i.e., an active radio frequency component used for transmission.

[0055] In some embodiments, the AIoT device may be a tag or other low-power IoT device.

[0056] In some embodiments, a non-tag terminal or network-side device can act as a tag reader, which can be an RFID tag.

[0057] In some embodiments, the information transmission between the reader and the tag can be as shown in Figure 2, and the reader operation instructions can be as shown in Table 1:

[0058] Table 1:

[0059] In some embodiments, the status of the label is as shown in Table 2:

[0060] Table 2:

[0061] It should be noted that Tables 1 and 2 above are only examples of information transmission between the reader and the tag. In this embodiment of the application, no specific limitations are made on the information transmission between the reader and the tag.

[0062] The IoT communication methods, apparatus, and devices provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0063] Please refer to Figure 3, which is a flowchart of an IoT communication method provided in an embodiment of this application. As shown in Figure 3, it includes the following steps:

[0064] Step 301: The communication device sends a first message, which is used to determine the transmission resources.

[0065] The aforementioned communication equipment can be a network-side device or terminal, or a reader for AIoT devices.

[0066] Sending the first message can be done by sending the first message to one or more IoT devices, which can be AIoT devices or other IoT devices.

[0067] The first message used to determine the transmission resource may indicate the transmission resource, specifically, it may be an explicit or implicit indication of the transmission resource; or the first message may be associated with the transmission resource, thereby allowing the transmission resource to be determined through the first message.

[0068] Step 302: The communication device receives a second message sent by the IoT device through the transmission resources.

[0069] The above-mentioned communication device receiving the second message sent by the IoT device through the transmission resource can be understood as follows: after receiving the first message, the IoT device determines the transmission resource based on the first message and sends the second message to the communication device through the transmission resource.

[0070] When the first message is sent to multiple IoT devices, the transmission resources can include the transmission resources corresponding to each of these IoT devices, so that each IoT device can use its own corresponding transmission resources to send the second message to the communication device.

[0071] The second message can carry the communication content between the IoT device and the communication device, so as to realize the transmission of communication content between the IoT device and the communication device through the transmission resources; the second message can also carry information such as the identification information of the IoT device, so as to realize the inventory of the IoT device.

[0072] In some implementations, the aforementioned IoT device may be an IoT device specified by the aforementioned communication equipment, or an IoT device specified by the core network equipment, or an IoT device specified by the server; specifically, it may be a particular IoT device.

[0073] In this embodiment of the application, since the communication device receives the second message sent by the IoT device through the transmission resources determined by the first message, that is, the transmission resources for transmitting the second message are determined based on the first message, the communication device and the IoT device can perform non-competitive transmission, thereby improving communication efficiency.

[0074] In this embodiment, since the transmission resources are determined by the first message sent by the communication device, IoT devices can perform non-contention-based access and transmission under the control of the communication device, improving communication efficiency and reducing latency overhead. This reduces network complexity and overhead while ensuring transmission performance, and improves the efficiency of the communication system. For example, for AIoT devices, non-contention-based access and transmission can be achieved under the control of the reader, ensuring communication efficiency and low latency performance.

[0075] As an optional implementation, the first message includes at least one of the following:

[0076] Paging messages, downlink (DL) messages, and reader-to-device (R2D) messages.

[0077] The above paging message can be understood as a message during the paging process, such as message (Message, Msg)0.

[0078] The aforementioned DL message can also be called DL signaling, and the aforementioned R2D message can also be called R2D signaling.

[0079] This implementation can support multiple message determination transmission resources to meet the needs of different scenarios or services.

[0080] As an optional implementation, the first message includes at least one of the following:

[0081] First high-layer signaling, at least one device identifier, indication information of the transmission resource, transmission indication information, and a temporary identifier effective within the scope of the communication device;

[0082] The IoT device belongs to the IoT device corresponding to the at least one device identifier, the transmission indication information is used to indicate the transmission behavior between the IoT device and the communication device, and the temporary identifier includes the temporary identifier of the IoT device corresponding to the at least one device identifier.

[0083] The aforementioned first-level signaling can be inventory signaling or other specific commands, such as Read, Write, Kill, etc.

[0084] The aforementioned first-layer signaling can be used to control the IoT devices, thereby improving the control effect of the IoT devices.

[0085] In some implementations, the first message described above may not include the first higher-layer signaling.

[0086] The above-mentioned IoT devices belonging to the IoT devices corresponding to the at least one device identifier can be understood as the IoT devices in step 302 being the IoT devices corresponding to the at least one device identifier.

[0087] The aforementioned device identifier can be the identifier of a single IoT device or the identifier of a group of IoT devices. Furthermore, the device identifier can be temporary or permanent; specifically, it can be a temporary unique identifier within the network of a network-side device, a temporary unique identifier assigned to a server within a certain range, or a globally unique identifier for the device.

[0088] In some implementations, the device identifier in this application embodiment may include at least one of the following:

[0089] Device identifiers, device group identifiers, and device characteristic information are used to identify individual devices.

[0090] The device identifier used to identify a single device can be understood as one identifier being specific to only one IoT device.

[0091] The aforementioned device group identifier is used to identify groups of IoT devices. When the device group identifier is a temporary identifier assigned to a group of IoT devices by a network-side device or server, it can have the same or similar format as the temporary identifier assigned to an individual IoT device, such as the same number of bits. However, it is necessary to clearly distinguish that the value range of the device group identifier is different from the value range of the temporary identifier for an individual IoT device, or to carry a displayed group identifier indication / individual device identifier indication, etc., to facilitate communication devices in determining whether it is targeting a single specific device, rather than a group of devices.

[0092] The aforementioned device group identifiers can save message overhead.

[0093] The aforementioned device feature information is used to represent the characteristics of IoT devices. This allows device identification to be achieved through device feature information. If the total number of devices that match the device feature information is determined or known (e.g., informed to the reader by the network-side device or server) and / or the order of devices that match the device feature information is determined or known, then the communication device can be identified as the specified IoT device.

[0094] The aforementioned device characteristic information enables non-contention communication between IoT devices and those with specified device characteristics, thereby improving the flexibility of the communication system.

[0095] In some implementations, the device identifier includes:

[0096] The communication device receives the device identifier from the network-side device or the server.

[0097] The device identifier received by the aforementioned communication device from the network-side device or server may be a message containing at least one of the aforementioned device identifiers sent by the network-side device or server before the communication device sends the aforementioned first message, thereby enabling the IoT device communicating with the aforementioned communication device to be the IoT device specified by the network-side device or server.

[0098] This allows the IoT devices that can communicate with the communication equipment without contention to be designated by the aforementioned network-side devices or servers, thereby enabling non-contention communication for designated IoT devices and improving communication flexibility.

[0099] Furthermore, the aforementioned network-side devices can be core network devices or wireless access network devices. For core network devices, they can initiate Inventory or Command procedures for one or more specific IoT devices. Communication devices (such as Readers) send Paging messages or other R2D / DL messages to the specific IoT devices. These messages can carry the IoT device's device identifier, dedicated resources allocated to the IoT device, temporary identifiers, and instructions for subsequent steps. The designated IoT device then responds on its dedicated resources, sends messages to higher layers, and performs subsequent communication according to the instructions from the communication device.

[0100] In some implementations, the first message does not include at least one device identifier. For example, in some scenarios, the communication device may send the first message only to a designated IoT device.

[0101] The aforementioned transmission resource indication information is used to indicate the aforementioned transmission resources. In the case of multiple IoT devices, the aforementioned indication information can indicate the dedicated resources of each IoT device, or multiple IoT devices can select their respective dedicated resources from multiple transmission resources according to preset rules.

[0102] The aforementioned transmission resource indication information allows for a simple and direct determination of the dedicated resources for each IoT device, thereby improving the accuracy of communication.

[0103] In some implementations, when the first message does not include the indication information of the transmission resources, the transmission resources may be implicitly indicated by the first message. For example, the first message may implicitly indicate n time slots or n symbols between the first messages as the transmission resources, or implicitly indicate time-domain or frequency-domain resources adjacent to the first message as the transmission resources.

[0104] The temporary identifier that is effective within the scope of the aforementioned communication device can be understood as being effective only within the scope of the aforementioned communication device. For example, the aforementioned temporary identifier is assigned a value to the aforementioned communication device, such as the Reader Radio Network Temporary Identity (R-RNTI).

[0105] The aforementioned temporary identifier, including the temporary identifier of the IoT device corresponding to the at least one device identifier, can be understood as the aforementioned first message including the temporary identifier of the IoT device corresponding to the at least one device identifier. However, if the aforementioned first message does not include the at least one device identifier, it may still include the aforementioned temporary identifier. For example, if the IoT device corresponding to the at least one device identifier is a pre-specified or default IoT device, then the aforementioned first message includes the temporary identifier of the pre-specified or default IoT device.

[0106] Since the first message includes the temporary identifier, the communication device can schedule or identify the IoT device based on the temporary identifier during subsequent communication, thereby avoiding the easy leakage of the IoT device identifier due to the subsequent use of the device identifier for scheduling or identification, and thus improving communication security.

[0107] In some implementations, the first message may not include the temporary identifier. For example, in some scenarios, the device identifier may be used directly for scheduling or identification in subsequent scheduling or identification processes.

[0108] The transmission behavior between the IoT device and the communication device indicated by the above transmission indication information may include any transmission behavior between the communication device and the IoT device from the start to the end of communication, such as: indicating the transmission resources of the first message, or indicating the transmission resources of the second message, or indicating the content transmitted by the IoT device to the communication device, or indicating the content transmitted by the communication device to the IoT device, etc.

[0109] Since the first message includes the aforementioned transmission instruction information, it can clearly indicate the transmission behavior between the IoT device and the communication device to the IoT device, so that the communication device can control and select the communication process between the IoT device and the communication device, thereby improving the transmission reliability between the IoT device and the communication device.

[0110] In some implementations, the transmission indication information is used to indicate one of the following transmission behaviors between the IoT device and the communication device:

[0111] Send a random number to the communication device;

[0112] Do not send random numbers to the communication device;

[0113] The communication device sends the temporary identifier to the Internet of Things device;

[0114] The random number is used for at least one of the following: scheduling the IoT device, identifying the IoT device.

[0115] The above random number is a random number generated by the IoT device. For example, the above random number can be a random number (RN)16, or other random numbers, such as random numbers with fewer or more than 16 bits.

[0116] Since the random number is used to schedule and identify the IoT device, the communication device can schedule or identify the IoT device based on the random number in subsequent communication processes. This avoids the easy leakage of the IoT device's device identifier due to the subsequent use of the device identifier for scheduling or identification, thereby improving communication security.

[0117] In the absence of sending random numbers to the communication device, the aforementioned temporary identifier can be used for subsequent scheduling or identification.

[0118] The aforementioned communication device may send the temporary identifier to the IoT device during the aforementioned first message.

[0119] In this embodiment, since the above-mentioned transmission behavior is indicated, the IoT device can communicate using the indicated transmission behavior, thereby improving the transmission reliability between the IoT device and the communication device.

[0120] In some implementations, when sending a random number to the communication device:

[0121] The second message includes the random number, as well as at least one of the identification information of the IoT device and first high-level data;

[0122] Alternatively, the second message may include a random number, and at least one of the IoT device's identification information and first high-level data may be sent to the communication device via a message other than the second message.

[0123] The identification information of the Internet of Things mentioned above can be a globally unique identifier or a high-level identifier, such as an Electronic Product Code (EPC), and can be an identifier configured by core network equipment or servers, such as the device identifier described in the above embodiments.

[0124] The aforementioned first high-level data can be high-level data that IoT devices need to send to communication devices, such as high-level data in response to the first high-level signaling of IoT devices.

[0125] In this embodiment, at least one of the following can be transmitted via the second message: a random number, the identification information of the IoT device, and the first high-level data, thereby saving transmission overhead.

[0126] The message other than the second message mentioned above can be the fourth message described in the following implementation.

[0127] In the above embodiments, since at least one of the above-mentioned random number, IoT device identification information and first high-level data is transmitted through different messages, it is possible to transmit the IoT device identification information and first high-level data after the random number is successfully transmitted, thereby improving the transmission reliability of the IoT device identification information and first high-level data.

[0128] It should be noted that in some implementations, the first message may not include the transmission indication information, such as the transmission behavior between the IoT device and the communication device as agreed upon or pre-configured by the protocol.

[0129] As an optional implementation, the transmission resources include at least one of the following:

[0130] The default transport resource associated with the first message, and the transport resource indicated by the first message.

[0131] The aforementioned associated default transmission resources can be determined based on preset rules or protocols, such as time-domain or frequency-domain resources adjacent to the first message, or fixed-size transmission resources spaced n time slots or symbols away from the first message. Using these default transmission resources associated with the first message can save on transmission overhead.

[0132] The transmission resource indicated by the first message can be a transmission resource explicitly or implicitly indicated by the first message.

[0133] The transmission resources indicated by the first message above allow for more flexible resource configuration for IoT devices.

[0134] As an optional implementation, the communication device sends a first message, including:

[0135] The communication device sends the first message to N Internet of Things devices;

[0136] The transmission resources include N transmission resources, each of which is a dedicated transmission resource for the N IoT devices, where N is a positive integer.

[0137] The aforementioned N IoT devices can be one or more IoT devices.

[0138] For multiple IoT devices, the dedicated transmission resources for each IoT device can be as indicated by the first message mentioned above, or the multiple IoT devices can determine their respective transmission resources based on preset rules or protocol agreements. For example, N transmission resources can be determined according to the order of the IoT devices to determine their respective dedicated transmission resources.

[0139] In this implementation, each IoT device is configured with its own dedicated transmission resources to avoid transmission conflicts between IoT devices and improve transmission reliability.

[0140] As an optional implementation, the second message includes at least one of the following:

[0141] The identification information, first high-level data, and random number of the IoT device;

[0142] The random number is used for at least one of the following: scheduling the IoT device, identifying the IoT device.

[0143] The identification information, first high-level data, and random number mentioned above are described in the corresponding descriptions of the above implementation methods, and will not be repeated here.

[0144] In this embodiment, at least one of the identification information, first high-layer data, and random number of the IoT device can be transmitted using the aforementioned transmission resources, thereby improving the transmission efficiency and reliability of at least one of the identification information, first high-layer data, and random number of the IoT device.

[0145] In some embodiments, after the communication device receives the second message sent by the IoT device through the transmission resource, the method further includes:

[0146] The communication device sends a third message to the IoT device, the third message including at least one of the following:

[0147] The confirmation information of the random number and the second higher-level signaling.

[0148] The confirmation information for the above random number can be an acknowledgment (ACK) of the random number.

[0149] The aforementioned second layer signaling can be signaling other than the aforementioned first layer signaling, such as Write, Lock, etc.

[0150] Sending confirmation of the random number can notify the IoT device that the random number was successfully sent, thereby improving the transmission reliability between the IoT device and the communication device.

[0151] Sending the aforementioned second-layer signaling enables greater control over IoT devices, thereby improving the effectiveness of IoT device control.

[0152] It should be noted that in some implementations, the confirmation of the random number may not be sent, such as by implicitly indicating successful transmission of the random number through the second higher-layer signaling. Alternatively, in some implementations, the IoT device assumes successful transmission of the second message after sending the second message.

[0153] In some implementations, the third message includes confirmation information for the random number, and after the communication device sends the third message to the IoT device, the method further includes:

[0154] The communication device receives a fourth message sent by the IoT device, the fourth message including at least one of the following:

[0155] The identification information of the IoT device and the second high-level data.

[0156] The aforementioned second high-level data may be high-level data other than the aforementioned first high-level data, or high-level data that is the same as the aforementioned first high-level data.

[0157] In this implementation, the identification information and high-level data of the IoT device can be sent after receiving the third message, thereby improving the transmission reliability of the identification information and high-level data of the IoT device. For example, the identification information and high-level data of the IoT device can be sent after receiving the confirmation information of the random number.

[0158] As an optional implementation, before the communication device sends the first message, the method further includes:

[0159] The communication device receives a fifth message sent by a network-side device or a server, the fifth message including at least one of the following:

[0160] Third-layer signaling, at least one device identifier;

[0161] The IoT device belongs to the IoT device corresponding to the at least one device identifier.

[0162] The aforementioned network-side equipment can be core network equipment.

[0163] The aforementioned third-layer signaling can be inventory signaling or other commands, such as Read, Write, Kill, etc. Furthermore, the aforementioned third-layer signaling can include the aforementioned first-layer signaling or the aforementioned second-layer signaling.

[0164] The fifth message mentioned above can represent a communication request for an IoT device corresponding to at least one of the above device identifiers. When a communication device receives a communication request for one or more specified IoT devices from a network-side device or server, such as receiving an inventory or various command requests, the communication device identifies the corresponding IoT device based on the above device identifier and communicates with these IoT devices.

[0165] In this implementation, the aforementioned IoT devices can be designated by the network-side device or server, and communication between the IoT devices and the communication devices can be triggered by the network-side device or server, thereby improving the flexibility of controlling or managing IoT devices. Specifically, when the network-side device or server designates one or more IoT devices to initiate an inventory or command, high-level data transmission between the communication devices and the IoT devices can be completed through non-competitive resources. This ensures the success rate of communication, reduces signaling overhead and processing complexity on the network side, and improves the overall network efficiency, capacity, and coverage.

[0166] In this embodiment, a communication device sends a first message to determine transmission resources; the communication device then receives a second message sent by an IoT device using those transmission resources. Since the communication device receives the second message sent by the IoT device using the transmission resources determined by the first message, the transmission resources for transmitting the second message are determined based on the first message. This achieves non-competitive transmission between the communication device and the IoT device, thereby improving communication efficiency.

[0167] Please refer to Figure 4, which is a flowchart of another IoT communication method provided in an embodiment of this application. As shown in Figure 4, it includes the following steps:

[0191] The identification information, first high-level data, and random number of the IoT device;

[0193] Optionally, after the IoT device sends a second message to the communication device through the transmission resources, the method further includes:

[0194] The IoT device receives a third message sent by the communication device, the third message including at least one of the following:

[0195] The confirmation information of the random number and the second higher-level signaling.

[0196] Optionally, the third message includes confirmation information for the random number. After the IoT device receives the third message sent by the communication device, the method further includes:

[0197] The fourth message sent by the IoT device to the communication device includes at least one of the following:

[0198] The identification information of the IoT device and the second high-level data.

[0199] It should be noted that this embodiment is an implementation method of the Internet of Things device corresponding to the embodiment shown in Figure 3. For the specific implementation method, please refer to the relevant description of the embodiment shown in Figure 3. In order to avoid repeated description, this embodiment will not be repeated.

[0200] The following examples, using a communication device as a reader and an IoT device as an AIoT device, illustrate the methods provided in this application through multiple embodiments:

[0201] Example 1:

[0202] This embodiment provides an overall description of the Reader's control mechanism, specifically outlining the overall framework of the solution and emphasizing the Reader's complete control over subsequent detailed processing.

[0203] Firstly, in this embodiment, the goal of communication is for the network-side device or server to complete Inventory or Command communication processes with one or more designated AIoT devices. Inventory generally refers to the inventory process. Upon receiving Inventory information, the AIoT device needs to report specified information, such as its device identifier and EPC ID, so that the network side can obtain information such as the number, attributes, and location of the devices. Commands typically include instructions such as Read, Write, and Kill, requiring the device to read or write specific content, or to perform removal operations on the device. These Commands generally require a response or confirmation from the device.

[0204] When a network-side device or server initiates an Inventory or Command procedure for one or more AIoT devices as needed, it sends the signaling details to the Reader via the core network interface or server interface. This includes, for example, Inventory or Command / Read / Write / Kill instructions, along with the device identifiers of one or more corresponding devices. The device identifier can be a temporary, unique identifier assigned to the device by the network-side device or server within a certain range, or it can be a globally unique identifier for the device. However, due to security and privacy concerns, the former is more suitable for plaintext transmission, while the latter requires secure transmission methods.

[0205] Next, the Reader receives signaling from the network-side device or server (i.e., the fifth message in the above embodiment), and determines from the device identification information that this is a communication request for one or more specified AIoT devices. The method of determining based on the device identification information can be at least one of the following:

[0206] A device identifier is one or more identifiers that are specific to a single device. It can be in any form, such as a temporary identifier or a permanent identifier, but each identifier is only for one specific device.

[0207] The device identifier needs to be identified as a group identifier. When the group identifier is a temporary identifier assigned to a group of devices by a network-side device or server, the group identifier may have the same or similar format as the temporary identifier assigned to a single device; for example, the same number of bits. However, it is necessary to clearly distinguish that the value range of the group identifier is different from the value range of the temporary identifier of a single device, or to carry a display of group identifier indication / single device identifier indication, etc., so that the Reader can determine that it is for a single specific device, rather than a group of devices.

[0208] If the device identifier is clearly a group identifier, and the group member information of the group identifier is relatively clear (e.g., the network-side device or server informs the Reader), such as the total number of devices in the group corresponding to the group identifier, and the order of each device in the group is predefined or preconfigured. For example, if the group has 10 devices, and the order of the devices in the group is 0-9, each corresponding to a specific 10 devices, then the Reader also clearly knows the number of devices and the specific correspondence of each device. This can also be used to determine one or more specified devices.

[0209] If the device identifier is a group identifier and the information of the group members is uncertain, such as not knowing the total number of devices in the group or the order of the devices in the group, then it cannot be identified as a specified AIoT device. In this case, the reader can use other methods to identify the specified AIoT device.

[0210] Device characteristic information: If the device identifier is given by device characteristic information, and the total number of devices that match the device characteristic information is uncertain, or the order of devices that match the device characteristic information is also uncertain, then it is generally judged as a non-designated AIoT device.

[0211] Device characteristic information: If the device identifier is given by device characteristic information, and the total number of devices that match the device characteristic information is determined or known (e.g., informed to the Reader by network-side devices or servers), and / or the order of devices that match the device characteristic information is determined, then it can be identified as the specified AIoT device.

[0212] The Reader can perform precise control over the signaling process of sending messages to one or more specified AIoT devices to ensure communication efficiency and latency performance. The information sent by the Reader to the AIoT devices can be carried using Paging messages or other R2D / DL signaling, and the content includes at least one of the following:

[0213] The signaling content of higher layers (i.e., the first higher layer command in the above embodiment), such as the Inventory command, the Command command, and the specific content of the Command command, such as Read, Write, Kill, etc.;

[0214] The targeted device identification information (i.e., at least one device identifier in the above embodiments), such as device identifier ID, or a list of device identifier IDs;

[0215] Dedicated resources are allocated to each specified AIoT device. When there is only one AIoT device, the dedicated resources are directly targeted at that UE. If there are multiple devices, the correspondence between the dedicated resource list and the multiple AIoT devices can be either default or specified. For example, N dedicated resources, N time slots, N frequency resources, or N resource blocks are assigned sequentially to the N devices according to the order in the device identifier list. The device at the first position in the device identifier list corresponds to the first dedicated resource, and so on, with the device at the nth position in the device identifier list corresponding to the nth dedicated resource. Alternatively, a specified method can be used, such as device identifier 1 carrying the corresponding dedicated resource or resource identifier, and so on. Each device identifier displays or indicates the corresponding resource.

[0216] Assign a valid temporary identifier from the Reader to the specified AIoT device for subsequent data scheduling and transmission. This can be done for one device, multiple devices, or all devices involved in this command. Each device has its own unique temporary identifier.

[0217] To indicate subsequent steps to a specified device (i.e., the transmission indication information in the above embodiments), such as the execution method of a command, there may be multiple steps to choose from, such as instructing the AIoT device to execute method 1 (i.e., the method provided in Embodiment 2 below), or other methods, or instructing how step 1 is sent, the content in Msg1, etc.

[0218] After receiving the Paging and R2D / DL signaling from the Reader, the designated AIoT device initiates subsequent communication processes according to the Reader's instructions to complete the entire signaling flow.

[0219] Example 2:

[0220] The communication method in this embodiment can be called Method 1. The request sent by the network-side device or server to the reader is detailed in Embodiment 1. The focus of this embodiment is the interaction steps between the reader and the AIoT device, as shown in Figure 5, including the following steps:

[0221] Step 1: The Reader sends a Msg0 message (i.e., the first message in the above embodiment) to the AIoT device. This message can be a Paging message or other R2D message type. The message carries high-level signaling content from the core network or server, such as Inventory, Command (e.g., Read, Write, Kill, etc.), and also carries the device identifier or a list of device identifiers targeted by this signaling. For example, it may contain one or more device identifiers for a single device. Optionally, dedicated transmission resources may be allocated to each AIoT device involved, either implicitly or explicitly.

[0222] For example, if there is only one device, then the default Msg1 resource after Msg0 is dedicated to that device. If there is more than one device, then Msg0 can carry multiple resource blocks, such as N time slots, N frequencies, and N time-frequency resource blocks, which correspond to each device in the AIoT device ID in sequence, specifically in a one-to-one correspondence.

[0223] Step 2: After receiving the Msg0 message, the designated AIoT device acquires its own dedicated transmission resources in sequence and sends the Msg1 message (i.e., the second message in the above embodiment) to the Reader on its own dedicated resources. The Msg1 message is a response to the higher-level message content in Msg0. For example, for Inventory, the AIoT device can return its own EPC ID; for Read information, the AIoT device can return the data content that was requested to be read; for Write message, the AIoT device can return confirmation information that the write is completed, etc. In short, the Msg1 message contains the EPC ID and / or higher-level data content and is sent to the Reader on the designated dedicated resources.

[0224] Next: Since Msg1 is a dedicated resource, there is no conflict or competition. On the dedicated resource of each device, the Reader reads the feedback Msg1 message of that device and sends the higher-level EPC ID or higher-level data content in the Msg1 message to the core network or server.

[0225] In particular, if the expected Msg1 message from the UE is not correctly received on the designated dedicated resource, the Reader can determine that the process has failed, and can continue to complete the communication process for the failed device by retransmitting a new Msg0 message and receiving a Msg1 message.

[0226] For AIoT devices, under the control of Msg0 information and parameters, the transmission of Msg1 does not require any failure detection or active recovery. The Reader is fully responsible for judging process failures and retransmission to ensure the reliability and completion of information transmission.

[0227] Example 3:

[0228] The communication method in this embodiment can be called Method 2. The request sent by the network-side device or server to the Reader is detailed in Embodiment 1. The focus of this example is the interaction steps between the Reader and the AIoT device. Specifically, based on Embodiment 1, another detailed interaction step between the Reader and the AIoT device is given to complete the entire signaling flow, as shown in Figure 6, including the following steps:

[0229] Step 1 (similar to Example 2): The Reader sends a Msg0 message (i.e., the first message in the above example) to the AIoT device. This message can be a Paging message or other R2D message type. The message carries the higher-level signaling content of the core network or server, such as Inventory, Command (Read, Write, Kill, etc.), and also carries the device identifier or list of device identifiers targeted by this signaling, such as one or more AIoT device IDs for a single device. Optionally, dedicated transmission resources are allocated to each AIoT device involved in an implicit or explicit manner.

[0230] For example, if there is only one device, then the default Msg1 resource after Msg0 is dedicated to that device. If there is more than one device, then multiple resource blocks can be carried in Msg0, such as N time slots, N frequencies, and N time-frequency resource blocks, which correspond to each device in the AIoT device ID in sequence, specifically in a one-to-one correspondence.

[0231] Specifically, Msg0 can also carry an indication requesting the AIoT device to send its own random number RN16 in Msg1 for subsequent scheduling. This is a significant difference between Embodiments 2 and 3 regarding Msg0: Msg0 carries whether Msg1 needs to send the device's RN16, or whether there is an indication for subsequent scheduling. Of course, explicitly distinguishing Msg0 in Embodiments 2 and 3 using signaling methods represents a coexistence of both approaches. Alternatively, the standard might adopt a default approach, where Msg0 does not carry any subsequent indication or RN16 indication, and the AIoT device simply follows the instructions in Embodiments 2 or 3 as specified in the standard.

[0232] Step 2: After receiving the Msg0 message, the designated AIoT device acquires its own dedicated resources in sequence and sends the Msg1 message (i.e., the second message in the above embodiment) to the Reader on its own dedicated resources. The Msg1 message is a response to the higher-level message content in Msg0. For example, for Inventory, the AIoT device can return its EPC ID; for Read information, the AIoT device can return the data content that was requested to be read; for Write message, the AIoT device can return confirmation information that the write is completed, etc. In short, the Msg1 message contains the EPC ID and / or higher-level data content and is sent to the Reader on the designated dedicated resources.

[0233] Since Msg0 carries an explicit subsequent scheduling instruction or RN16 instruction, or the method in the standard selection embodiment three is used as the default method, in Msg1, the AIoT device also carries a random number RN16. This random number is randomly generated, or generated after randomization operation based on its own device ID, such as a hash function. The AIoT device carries RN16 in Msg1 and sends it to the reader.

[0234] Next: Since Msg1 is a dedicated resource, there is no conflict or competition. On the dedicated resource of each device, the reader reads the feedback Msg1 message of that device and sends the higher-level EPC ID or higher-level data content in the Msg1 message to the core network or server.

[0235] The Reader reads RN16 from Msg1 and determines whether RN16 conflicts with the random numbers of other devices. If there is no conflict, it confirms that RN16 can be used as the unique identifier of the device under this Reader for subsequent scheduling and transmission of the AIoT device.

[0236] Step 3: The Reader sends a Msg2 message (i.e., the third message in the above embodiment) to the AIoT device. This message contains an acknowledgment of the RN16 sent by the device in Msg1, which means that the reader has correctly received the Msg1 message and that the device's RN16 is valid and can be used for subsequent identification and scheduling. Optionally, other higher-layer signaling information can also be carried in Msg2.

[0237] When an AIoT device receives the RN16 acknowledgment from Msg2, it considers its access process successful. It stores the RN16 for subsequent scheduling and identification. If other messages are present in Msg2, it processes and responds accordingly. Alternatively, it can use the RN16 as an identifier for its own message transmission and scheduling after Msg2.

[0238] If the AIoT device does not receive the RN16 acknowledgment from Msg2 within a specific time period, such as the next R2D time slot or after the timer / window expires, the AIoT device can consider the communication to have failed.

[0239] If the Reader fails to receive Msg1 on the dedicated resource, it can determine that the AIoT device has failed and resend Msg0 to ensure reliability and success rate. Alternatively, if the Reader fails to send Msg2, and the AIoT device has not correctly stored and acknowledged RN16 as its valid identifier, and the Reader, due to the lack of feedback after sending Msg2, defaults to using RN16 as the identifier for subsequent scheduling of the device, and there is no expected response in subsequent scheduling, it can recognize the failure and initiate the process of synchronizing RN16 again.

[0240] Example 4:

[0241] The communication method in this embodiment can be called Method 3. The request sent by the network-side device or server to the Reader is detailed in Embodiment 1. The focus of this example is the interaction steps between the Reader and the AIoT device. Specifically, based on Embodiment 1, another detailed interaction step between the Reader and the AIoT device is given to complete the entire signaling flow, as shown in Figure 7, including the following steps:

[0242] Step 1 (similar to Example 2): The Reader sends a Msg0 message (i.e., the first message in the above example) to the AIoT device. This message can be a Paging message or other R2D message type. The message carries the higher-level signaling content of the core network or server, such as Inventory, Command (Read, Write, Kill, etc.), and also carries the device identifier or list of device identifiers targeted by this signaling, such as one or more AIoT device IDs for a single device. Optionally, dedicated transmission resources are allocated to each AIoT device involved in an implicit or explicit manner.

[0243] For example, if there is only one device, then the default Msg1 resource after Msg0 is dedicated to that device. If there is more than one device, then multiple resource blocks can be carried in Msg0, such as N time slots, N frequencies, and N time-frequency resource blocks, which correspond to each device in the AIoT device ID in sequence, specifically in a one-to-one correspondence.

[0244] In particular, Msg0 can also carry a unique identifier assigned to the AIoT device (i.e., the temporary identifier in the above embodiment) for subsequent scheduling. When there are multiple devices, each device can be assigned a unique identifier, or some devices can be assigned one identifier and some do not need to be assigned one identifier, as long as all are clearly identified.

[0245] This is a significant difference regarding Msg0 in Embodiments 2, 3, and 4. Embodiment 2 is more suitable for single transmissions, while Embodiments 3 and 4 assign RN16 to the device for subsequent scheduling and device identification, facilitating subsequent data transmission. The difference between Embodiments 3 and 4 is that in Embodiment 3, the AIoT device selects RN16, and the Reader confirms its validity, while Embodiment 4 is more direct, with the Reader directly assigning a temporary identifier (such as RN16). Since the Reader can ensure uniqueness during assignment, it is more efficient.

[0246] Step 2: After receiving the Msg0 message, the designated AIoT device acquires its own dedicated resources in sequence and sends the Msg1 message (i.e., the second message in the above embodiment) to the reader on its own dedicated resources. The Msg1 message is a response to the higher-level message content in Msg0. For example, for Inventory, the AIoT device can return its EPC ID; for Read information, the AIoT device can return the data content that was requested to be read; for Write message, the AIoT device can return confirmation information that the write is completed, etc. In short, the Msg1 message contains the EPC ID and / or higher-level data content and is sent to the Reader on the designated dedicated resources.

[0247] The AIoT device receives the temporary identifier assigned by the Reader, stores it, and uses it as a device identifier and identification for subsequent signaling transmissions and scheduling.

[0248] Optionally, AIoT devices can also carry a temporary identifier again in the Msg1 message as an identifier for this Msg1. Alternatively, since Msg1 is a dedicated resource that can identify the user, the temporary identifier can be omitted.

[0249] Example 5:

[0250] The communication method in this embodiment can be called Method 4. The request sent by the network-side device or server to the Reader is detailed in Embodiment 1. The focus of this example is the interaction steps between the Reader and the AIoT device. Specifically, based on Embodiment 1, another detailed interaction step between the Reader and the AIoT device is given to complete the entire signaling flow, as shown in Figure 8, including the following steps:

[0251] Step 1 (similar to Example 2): The Reader sends a Msg0 message (i.e., the first message in the above example) to the AIoT device. This message can be a Paging message or other R2D message type. The message carries high-level signaling content from the core network or server, such as Inventory, Command (Read, Write, Kill, etc.), and also carries the device identifier or list of device identifiers targeted by this signaling, such as one or more AIoT device IDs for a single device. Optionally, dedicated transmission resources are allocated to each AIoT device involved in an implicit or explicit manner.

[0252] For example, if there is only one device, then the default Msg1 resource after Msg0 is dedicated to that device. If there is more than one device, then multiple resource blocks can be carried in Msg0, such as N time slots, N frequencies, and N time-frequency resource blocks, which correspond to each device in the AIoT device ID in sequence, specifically in a one-to-one correspondence.

[0253] Specifically, unlike embodiments two, three, and four, this embodiment expects to send only the RN16 of the AIoT device in Msg1, instead of directly carrying the EPC ID or higher-layer data. Therefore, if this embodiment needs to coexist with other embodiments, the Reader needs to explicitly indicate in Msg0 whether to send higher-layer information or RN16 directly in Msg1, or to indicate implicitly in Msg0. For example, when resources are large, it means that higher-layer information can be sent directly, and when resources are small, it means that RN16 should be sent first. Alternatively, for the method of this embodiment five, it can be directly selected from the standard specifications to enter the standard's normative behavior, and the UE can execute according to the specified behavior without any discrepancy.

[0254] Step 2: After receiving the Msg0 message, the designated AIoT device acquires its own dedicated resources in sequence and sends the Msg1 message (i.e., the second message in the above embodiment) to the Reader on its own dedicated resources. The Msg1 message carries the device's RN16. This random number is generated randomly or generated after randomization calculation based on its own device ID, such as a hash function. The AIoT device carries the RN16 in the Msg1 message and sends it to the Reader.

[0255] Next: Since Msg1 is a dedicated resource, there is no conflict or competition. On the dedicated resource of each device, the Reader reads the feedback Msg1 message of that device. The Reader reads RN16 in Msg1 and determines whether RN16 conflicts with the random numbers of other existing devices. If there is no conflict, it is confirmed that RN16 can be used as the unique identifier of the device under this Reader for subsequent scheduling and transmission of the AIoT device.

[0256] Step 3: The Reader sends a Msg2 message (i.e., the third message in the above embodiment) to the AIoT device. This message contains an acknowledgment of the RN16 sent by the device in Msg1, which means that the Reader has correctly received the Msg1 message and that the device's RN16 is valid and can be used for subsequent identification and scheduling.

[0257] When an AIoT device receives the RN16 acknowledgment from Msg2, it considers its access process successful. It stores the RN16 for subsequent scheduling and identification. If other messages are present in Msg2, it processes and responds accordingly. Alternatively, it can use the RN16 as an identifier for its own message transmission and scheduling after Msg2.

[0258] If the AIoT device does not receive the RN16 acknowledgment from Msg2 within a specific time period, such as the next R2D time slot or after the timer / window expires, the AIoT device can consider the communication to have failed.

[0259] If the Reader fails to receive Msg1 on the dedicated resource, it can determine that the AIoT device has failed and resend Msg0 to ensure reliability and success rate. Alternatively, if the Reader fails to send Msg2, and the AIoT device has not correctly stored and acknowledged RN16 as its valid identifier, and the Reader, due to the lack of feedback after sending Msg2, defaults to using RN16 as the identifier for subsequent scheduling of the device, and there is no expected response in subsequent scheduling, it can recognize the failure and initiate the process of synchronizing RN16 again.

[0260] Step 4: Upon successfully receiving its own RN16 confirmed device, the device initiates a new UL, D2R message transmission (i.e., the fourth message in the above embodiment). This message is a response to the higher-level message content in Msg0. For example, for Inventory, the AIoT device can return its EPC ID; for Read information, the AIoT device can return the data content that was requested to be read; for Write message, the AIoT device can return confirmation information that the write is completed, etc. In short, the Msg1 message contains the EPC ID and / or higher-level data content and is sent to the Reader on the specified dedicated resource.
