In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0170] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0171] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0172] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

[0173] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0174] Energy obtained from the environment can drive data transmission and wireless communication of sensing nodes. The current mainstream low-power IoT communication chips (such as BLE, LoRa, NB-IoT) have a transmit and receive power consumption of tens or even hundreds of milliwatts, while the energy obtained by environmental energy harvesting is only at the microwatt level, which is unable to drive these types of nodes to work. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens of microwatts or even less than ten microwatts. The current mainstream method uses backscatter communication technology. Backscatter Communications is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things, and is an important means to achieve "Intelligent Connection of Everything". The methods that can be used include backscatter transmission (Backscatter Communications) technology.

[0175] The first device 103 shown in FIG. 1 a may be any device that performs wireless communication using a backscatter transmission mechanism.

[0176] As shown in Figure 1b, the backscatter transmission mechanism is a wireless communication mechanism that utilizes the principle of radio frequency signal backscattering with extremely low-power modulation and transmission technology. A reader sends a physical layer signal to an ambient IoT device. This physical layer signal can be a pulse signal or other AC signal. In some embodiments, this physical layer signal is used to provide energy for the ambient IoT device to transmit the signal. Therefore, this physical layer signal can be referred to as an excitation signal or trigger signal. For example, since a portion of the excitation signal is reflected when it reaches the ambient IoT device, the ambient IoT device can adjust the matching between the receiving antenna and the impedance according to the intended information to enhance the reflection of the incident excitation signal and modulate the acquired sensor data onto the reflected signal to complete the data transmission. This process is similar to a reflector. Compared to other communication technologies, backscatter transmission does not require complex RF structures, reducing the use of components such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing. Therefore, it can simplify the design of ambient IoT devices and significantly reduce the cost of ambient IoT device nodes. Ambient IoT devices are IoT devices that use environmental energy to operate. This environmental energy can include the aforementioned wireless signal energy, as well as other environmental capabilities such as geothermal energy and / or light energy.

[0177] Here, the device that sends a physical layer signal to the ambient IoT device and triggers the ambient IoT device to return a reflected signal can be called an anchor point of the ambient IoT device reader.

[0178] It is worth noting that an ambient IoT device is a device that uses the backscatter transmission mechanism for wireless communication. In specific implementations, other devices can also use the backscatter transmission mechanism for wireless communication.

[0179] The anchor point or reader of the ambient IoT device may be a network node of a wireless communication network, such as an access network device, a relay node (or intermediate node), or a terminal.

[0180] Backscatter transmission network topologies can include one of the following:

[0181] Topology 1: As shown in Figure 1c, uplink (UL) and downlink (DL) data transmission is carried out directly between ambient IoT devices and access network devices.

[0182] Topology 2: As shown in Figure 1d, DL and UL data transmission occurs indirectly between ambient IoT devices and access network devices. Intermediate nodes (also called auxiliary nodes) provide forwarding services. These intermediate nodes can include relays, integrated access backhaul (IAB), user equipment (UE), and repeaters (RP).

[0183] Topology 3: As shown in Figure 1e, ambient IoT devices and access network devices directly transmit or receive data in the DL or UL. Auxiliary nodes are located on the UL or DL, responsible for receiving or sending UL or DL ​​data. Examples of auxiliary nodes include relays, integrated access backhaul (IAB) nodes, terminals, and network controlled repeaters (NCRs).

[0184] Topology 4: As shown in Figure 1f, the ambient IoT device and the UE directly receive and transmit data on the downlink and uplink. The UE collects data and forwards it to the network.

[0185] As shown in Figure 1g, devices that use the backscatter transmission mechanism for wireless communication can be divided into three types:

[0186] Device A: has no energy storage, cannot independently generate and / or amplify signals, and can only perform backscatter transmission.

[0187] Device B: Has energy storage, cannot generate signals independently, and can only perform backscatter transmission. The use of stored energy can include amplification of the backscattered signal.

[0188] Device C: has energy storage and can independently generate signals, that is, it has active radio frequency (RF) components for transmission.

[0189] In some embodiments, Ambient IoT technology can be applied to various communication scenarios, such as inventory management in large-scale warehouses and sensor networks. Accordingly, Ambient IoT devices need to support operations such as reading and writing information or executing other commands.

[0190] FIG2a is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG2a, the embodiment of the present disclosure relates to an information indication method, which is used in a communication system 100 and includes:

[0191] Step S2101: The second device sends a first signal.

[0192] In some embodiments, the second device sends the first signal to the first device.

[0193] In some embodiments, the first device receives the first signal.

[0194] In some embodiments, the first device may be any passive device, an ambient energy device, or an ambient IoT device.

[0195] Exemplarily, the first device may be device A, device B and / or device C shown in FIG. 1g .

[0196] The second device can be any endpoint that receives the first information. The endpoint is also the device corresponding to the receiving address of the first information, that is, the second device is the receiving device of the first information.

[0197] The second device may include but is not limited to a server or an application function (AF).

[0198] Exemplarily, the first device is an IoT device, and the second device may be an IoT server.

[0199] In some embodiments, the second device may be any network device located within the trust domain of the mobile communication network.

[0200] In some embodiments, the second device may be any network device located in the trust domain of the mobile communication network. Such a second device may be connected to the mobile communication network through a network open function or the like.

[0201] In some embodiments, the first signal may include but is not limited to: a radio frequency signal.

[0202] In some embodiments, the first signal may be a physical layer signal sent according to a preset sequence, and the physical layer signal may not carry any information content.

[0203] It is understandable that the first signal may be a simple excitation signal and may not carry any information.

[0204] In other embodiments, the first signal may be a signal carrying information content. After receiving the first signal, the first device may decode the first signal to extract the information carried in the first signal.

[0205] In some embodiments, the first device has backscatter communication capabilities.

[0206] In some embodiments, the first information may carry a task identifier, which identifies a task to be performed by the first device. For example, the task to be performed may include but is not limited to: information reporting, data writing, data deletion, data updating, data caching, etc.

[0207] In some embodiments, the first signal may carry a device identifier of the first device to which information is to be transmitted. Thus, if there are multiple first devices and multiple first devices receive the first signal, only the first device whose device identifier is carried in the first signal will transmit information in response to the first signal.

[0208] Step S2102: The first device determines the format of the information to be sent.

[0209] In some embodiments, the information to be sent is carried within a data frame; thus, the first device determining the format of the information to be sent can be understood as the first device determining the format of the data frame for the information to be sent. In other embodiments, the information to be sent can be carried within a protocol data packet (PDU); thus, the first device determining the format of the information to be sent can be understood as the first device determining the format of the PDU for the information to be sent.

[0210] In some embodiments, the first device, stimulated by the first signal, determines the format of a data frame for sending information.

[0211] It should be noted that the first device determines the format of the data frame for sending information under the stimulation of the first signal, which can be understood as: the first device determines the format of the data frame for sending information based on the energy of the first signal.

[0212] In some embodiments, the first device may determine the format of the data frame for sending information based on preset information.

[0213] It should be noted that the first device can determine the format of the data frame for sending information by itself.

[0214] Exemplarily, the first device is bound to a sensor, and the first device can determine the format of the data frame by reading preset data of the sensor.

[0215] In some embodiments, determining the format of the data frame may include one of the following:

[0216] Determining the format of the data frame according to the protocol;

[0217] or,

[0218] determining a format of the data frame according to a device type of the first device;

[0219] or,

[0220] The format of the data frame is determined according to an application scenario of the first device.

[0221] It should be noted that the format of the data frame may be determined according to a protocol agreement, or the format of the data frame may be determined according to the device type or application scenario of the first device.

[0222] It is understood that different types of devices have different capabilities, and the data frames they can transmit may contain different content and / or different lengths. For example, type 1 devices have the weakest capabilities, and data frames transmitted by type 1 devices may carry any of identification information, service information, and control information. For another example, type 3 devices have the strongest capabilities, and data frames transmitted by type 3 devices may carry identification information, service information, and / or control information.

[0223] In some embodiments, the application scenarios of the first device are different, and the content carried in the data frame sent by the first device may be different.

[0224] For example, if the application scenario of the first device is a cargo inventory scenario, the data frame sent by the first device may carry identification information.

[0225] As another example, if the application scenario of the first device is a sensor network scenario, the data frame sent by the first device may carry service information and / or identification information.

[0226] In some embodiments, data frames of different formats carry different information. It is understood that different types of first devices or first devices used in different scenarios can determine the format of the data frame based on the information content they need to send to the second device, thereby using an appropriate format to transmit information, thereby reducing signaling overhead and / or improving transmission reliability.

[0227] In some embodiments, the format includes at least one of the following:

[0228] A first format, where the data frame in the first format carries service information;

[0229] A second format, where the data frame in the second format carries control information;

[0230] The third format, the data frame of the third format carries identification information;

[0231] The fourth format, the data frame of the fourth format carries identification information and service information;

[0232] The fifth format, the data frame of the fifth format carries identification information and control information;

[0233] The sixth format, the data frame of the sixth format carries identification information, service information and control information;

[0234] The seventh format: the data frame of the seventh format carries service information and control information.

[0235] It is worth noting that data frames of different formats carry different information and the lengths of data frames may also be different.

[0236] In some embodiments, the service information is related to a type of service processed by the first device.

[0237] In some embodiments, the service information may include: sensor data measured by the first device.

[0238] For example, the service information may be temperature data, humidity data, speed data, concentration data of a substance to be sampled, etc. It is understandable that the data lengths corresponding to different service information may be different.

[0239] In some embodiments, the control information is used to indicate a response result of the first device to a control instruction sent by the second device.

[0240] In some embodiments, the first device determines a format of the control information. It is understandable that control information in different formats may carry different information.

[0241] In some embodiments, the format of the control information includes at least one of the following:

[0242] An eighth format, wherein the control information in the eighth format carries acknowledgment (ACK) information or negative acknowledgment (NACK) information;

[0243] Ninth format: the control information in the ninth format carries confirmation ACK information, or negative ACK information and failure reason.

[0244] It is understandable that when the first device receives the control instruction sent by the second device, the first device can determine the specific information carried in the control information based on its own response result to the control instruction.

[0245] Exemplarily, the control instruction is a data write instruction. If the first device successfully executes the data write instruction, ACK information carried by the control information is determined; if the first device fails to successfully execute the data write instruction, NACK information carried by the control information is determined.

[0246] Furthermore, in the case where the first device fails to respond to the control instruction, the first device may carry the failure reason of the response in the control information so that the second device can perform subsequent control based on the failure reason.

[0247] As another example, if the first device fails to successfully execute the data write instruction due to insufficient storage space, the first device may carry NACK information and the reason for failure in the control information; after receiving the control information, the second device may abandon the data writing, or resend the data deletion instruction and the data write instruction.

[0248] In some embodiments, the identification information includes:

[0249] Identification mark;

[0250] or,

[0251] The identification sequence is obtained by processing the identification identification based on a preset algorithm.

[0252] In some embodiments, the identification identifier may be a unique identification code pre-set for the first device or an object associated with the first device. For example, the identification identifier may be a device identifier of the first device; or the identification identifier may be a goods identifier of goods associated with the first device.

[0253] In some embodiments, the first device determines that the data frame carries an identification identifier, or the data frame carries the identification sequence.

[0254] In some embodiments, the first device determines an identification type of the identification.

[0255] In some embodiments, the identification type is used to indicate the encoding type of the identification identification.

[0256] It is understandable that the same identification mark may indicate different information with different identification types.

[0257] In some embodiments, the identification type of the identification identifier includes, but is not limited to:

[0258] Electronic Product Code (EPC);

[0259] and / or,

[0260] International Organization for Standardization / International Electro Technical Commission (ISO / IEC) code;

[0261] and / or,

[0262] User Identification (UID) code.

[0263] In some embodiments, the first device determines a data length of the identification tag.

[0264] In some embodiments, identification identifiers of different identification types have different data lengths; and / or identification identifiers of the same identification type have different data lengths.

[0265] Exemplarily, the data length of the identification mark obtained based on ISO / IEC encoding is 8 bits; the data length of the identification mark obtained based on UID encoding is 128 bits.

[0266] As another example, the data length of the identification mark obtained based on EPC encoding can be 96 bits, 256 bits, etc.

[0267] It is worth noting that the first device can directly send the identification identifier as identification information to the second device, or, in order to improve reliability, the first device can process the identification identifier based on a preset algorithm and send the processed identification sequence as identification information to the second device.

[0268] In some embodiments, the preset algorithm includes at least one of the following:

[0269] encryption algorithm;

[0270] Error correction algorithms;

[0271] Error detection algorithm.

[0272] In some embodiments, the encryption algorithm may include but is not limited to: MD5 algorithm, AES algorithm and DES algorithm.

[0273] It is understood that the first device encrypts the identification identifier using an encryption algorithm and carries the encrypted identification sequence in the data frame. After receiving the data frame, the second device can decrypt the identification sequence to obtain the identification identifier. In this way, even if the data frame sent by the first device is illegally obtained by another device, it cannot obtain the identification identifier contained in the data frame.

[0274] In some embodiments, the error correction algorithm may include, but is not limited to, a Reed Solomon algorithm and a BCH error correction algorithm.

[0275] It is understood that the first device processes the identification identifier using an error correction algorithm and carries the resulting identification sequence in the data frame. Upon receiving the data frame, the second device can verify the identification sequence to determine whether it contains errors. This allows the second device to detect errors and recover the data even if the data frame contains errors, thus reducing the likelihood of retransmissions by the first device.

[0276] In some embodiments, the error detection algorithm may include, but is not limited to, a cyclic redundancy check (CRC) algorithm and a longitudinal redundancy check (LRC) algorithm.

[0277] It is understood that the first device processes the identification identifier using an error detection algorithm and carries the resulting identification sequence in the data frame. After receiving the data frame, the second device can verify the identification sequence to determine whether the received identification sequence contains errors. In this way, if the second device determines that the information carried in the data frame is erroneous, it can request the first device to retransmit the data.

[0278] In some embodiments, the data frame includes: an indicator; the indicator indicates the format.

[0279] It is worth noting that by carrying an indicator in the data frame and using the indicator to indicate the format of the data frame, after the second device receives the information, it can determine the data frame format and information content used by the first device based on the indicator. In particular, for the case where the first device determines the format of the data frame by itself, it is convenient for the second device to quickly decode.

[0280] In some embodiments, the indicator includes at least one of the following:

[0281] A first indicator, used to indicate relevant information related to the identification information in the data frame;

[0282] A second indicator, used to indicate relevant information related to the service information in the data frame;

[0283] The third indicator is used to indicate relevant information related to the control information in the data frame.

[0284] It should be noted that the relevant information may include but is not limited to: data length, format, and identification type.

[0285] In some embodiments, the relevant information is used to assist the second device in decoding the identification information, service information and / or control information.

[0286] It should be noted that data frames of different formats carry different information and indicators.

[0287] In some embodiments, the first indicator indicates at least one of the following:

[0288] whether the data frame carries the identification information;

[0289] The identification type of the identification information carried by the data frame;

[0290] The data length of the identification information carried by the data frame.

[0291] In some embodiments, the first indicator may include one or more indicator bits. For example, different bit values ​​of the indicator bits indicate whether the data frame carries or does not carry identification information. Alternatively, different bit values ​​of the indicator bits indicate the identification type and / or data length of the identification information carried by the data frame.

[0292] In some embodiments, the identification type is used to indicate an encoding type of the identification information.

[0293] In some embodiments, the second indicator indicates at least one of the following:

[0294] whether the data frame carries the service information;

[0295] The data length of the service information carried by the data frame.

[0296] In some embodiments, the second indicator may include one or more indicator bits. For example, different bit values ​​of the indicator bits indicate whether the data frame carries or does not carry service information. Alternatively, different bit values ​​of the indicator bits indicate the data length of the service information carried by the data frame.

[0297] In some embodiments, the third indicator indicates at least one of the following:

[0298] whether the data frame carries control information;

[0299] The format of the control information carried by the data frame.

[0300] In some embodiments, the third indicator may include one or more indicator bits. For example, different bit values ​​of the indicator bits indicate whether the data frame carries or does not carry control information. Alternatively, different bit values ​​of the indicator bits indicate the format of the control information carried by the data frame.

[0301] In some embodiments, the encoding of the indicator carried by a data frame is independent of the encoding of the content carried by the data frame.

[0302] It is understood that the indicators and content carried in the data frame are encoded independently of each other, so that the decoding of the indicators can also be independent of the decoding of the content contained in the data frame. Therefore, after receiving the data frame sent by the first device, the second device can first decode the indicator in the data frame to determine the format of the data frame, and then decode the content carried by the data frame to ensure the correct decoding.

[0303] Step S2103: The first device sends information based on the first signal.

[0304] In some embodiments, the first device sends information based on a trigger or stimulus of the first signal.

[0305] In other embodiments, the first device sends information based on the signal energy of the first signal.

[0306] In some embodiments, the first device sends information to the second device based on the first signal.

[0307] In some embodiments, the second device receives information sent by the first device in response to the first signal.

[0308] Step S2104: The second device determines the format of the information sent by the first device.

[0309] In some embodiments, the information sent by the first device is carried by a data frame. Thus, the second device determines the format of the information sent by the first device, which can be understood as the second device determining the format of the data frame of the information sent by the first device.

[0310] In some embodiments, the second device determines the format of the transmitted information of the first device based on the indicator within the data frame of the information.

[0311] In some embodiments, the decoding of the indicator within the data frame is independent of the decoding of the content carried by the data frame.

[0312] It can be understood that the second device can first decode the information received from the first device to obtain an indicator; based on the indicator, determine the format of the data frame, and then decode the content carried by the data frame according to the format of the data frame, thereby improving decoding efficiency and ensuring the correctness of decoding.

[0313] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0314] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0315] The information indication method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2104. For example, steps S2101 to S2103 may be implemented as independent embodiments, but are not limited thereto.

[0316] In some embodiments, step S2104 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that if the format of the data frame of information transmitted by the first device can be specified by the second device, and if the data frame carries control information, the first device does not need to carry an indicator in the data frame, and thus does not need to determine the indicator. Alternatively, the second device can directly forward the data frame to another device without decoding the data frame.

[0317] FIG2b is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG2b, the embodiment of the present disclosure relates to an information indication method, which is used in a communication system 100 and includes:

[0318] Step S2201: The second device determines the format of the information sent by the first device.

[0319] In some embodiments, the transmitted information is carried in a data frame; thus, the second device determining the format of the information transmitted by the first device can be understood as the second device determining the format of the data frame of the information transmitted by the first device.

[0320] In other embodiments, the transmitted information may be carried in a protocol data packet (PDU); thus, the second device determining the format of the information transmitted by the first device may be understood as the second device determining the format of the PDU of the information transmitted by the first device. In some embodiments, determining the format of the data frame may include one of the following:

[0321] Determining the format of the data frame according to the protocol;

[0322] or,

[0323] determining a format of the data frame according to a device type of the first device;

[0324] or,

[0325] The format of the data frame is determined according to an application scenario of the first device.

[0326] It is understood that different types of first devices have different capabilities, and the data frames that can be sent by different types of first devices may contain different content and / or different lengths of data frames. For example, a first type device has the weakest capabilities, and the data frames sent by the first type device may carry any of identification information, service information, and control information. For another example, a third type device has the strongest capabilities, and the data frames sent by the third type device may carry identification information, service information, and / or control information.

[0327] In some embodiments, the application scenarios of the first device are different, and the content carried in the data frame sent by the first device may be different.

[0328] For example, if the application scenario of the first device is a cargo inventory scenario, the data frame sent by the first device may carry identification information.

[0329] As another example, if the application scenario of the first device is a sensor network scenario, the data frame sent by the first device may carry service information and / or identification information.

[0330] In some embodiments, data frames of different formats carry different information. It is understandable that when the second device determines the format of information to be sent to the first device, it will take into account different types of first devices or first devices used in different scenarios.

[0331] Based on this, the second device may determine the format of the data frame according to the protocol agreement, the device type or application scenario of the first device.

[0332] In some embodiments, the format includes at least one of the following:

[0333] A first format, where the data frame in the first format carries service information;

[0334] A second format, where the data frame in the second format carries control information;

[0335] The third format, the data frame of the third format carries identification information;

[0338] The sixth format, the data frame of the sixth format carries identification information, service information and control information;

[0339] The seventh format: the data frame of the seventh format carries service information and control information.

[0340] It is worth noting that data frames of different formats carry different information and the lengths of data frames may also be different.

[0341] In some embodiments, the service information is related to a type of service processed by the first device.

[0342] In some embodiments, the service information may include: sensor data measured by the first device.

[0343] For example, the service information may be temperature data, humidity data, speed data, concentration data of a substance to be sampled, etc. It is understandable that the data lengths corresponding to different service information may be different.

[0344] In some embodiments, the control information is used to indicate a response result of the first device to a control instruction sent by the second device.

[0345] In some embodiments, the second device determines the format of the control information. It is understandable that control information in different formats may carry different information.

[0346] In some embodiments, the format of the control information includes at least one of the following:

[0347] An eighth format, wherein the control information in the eighth format carries acknowledgment (ACK) information or negative acknowledgment (NACK) information;

[0348] Ninth format: the control information in the ninth format carries confirmation ACK information, or negative ACK information and failure reason.

[0349] It can be understood that the second device can specify the format of the control information sent by the first device, that is, the second device can specify the specific information carried by the control information sent by the first device.

[0350] In some embodiments, the identification information includes:

[0351] Identification mark;

[0618] In some embodiments, the network device sends a radio frequency signal to the ambient IoT device to activate the ambient IoT device and provide power to the ambient IoT device.

[0619] In some embodiments, the ambient IoT device reflects the RF signal and modulates the data frame within the reflected signal of the RF signal.

It is understood that when the network device specifies the format of the data frame of information sent by the environmental IoT device, the network device does not need to determine the format of the data frame based on the format indicator, and the data frame may not carry the format indicator.

[0624] FIG6b is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG6b , the embodiment of the present disclosure relates to an information indication method, and the method includes:

[0625] Step S6201: The network device determines the format of the data frame of the information sent by the environmental Internet of Things device.

[0626] Step S6202: The network device sends a radio frequency signal carrying instruction information to the environmental IoT device.

[0627] In some embodiments, the indication information indicates a format of a data frame specified by the network device.

[0628] In some embodiments, the environmental Internet of Things device receives indication information sent by the network device and determines the format of the data frame of the reported information based on the indication information.

[0629] It is understandable that the information content contained in the data frame of the information reported by the environmental Internet of Things device can be specified by the network device.

[0630] Step S6203: Based on the indication information, the environmental IoT device determines the format of the data frame.

[0631] It can be understood that the environmental Internet of Things device determines the information content of the data frame specified by the network device based on the indication information, and determines whether the data frame needs to carry a format indicator based on the information content of the specified data frame.

[0632] In some embodiments, the data frame may not need to carry a format indicator. For example, if the network device specifies that the data frame contains control information, the ambient IoT device does not need to carry the third format indicator in the data frame.

[0633] In some embodiments, a data frame may carry a first format indicator and / or a second format indicator. For example, if the network device specifies that a data frame includes a terminal index number and / or service information, the ambient IoT device needs to carry a first format indicator in the data frame to indicate the index type and index length of the terminal index number. For another example, if the network device specifies that a data frame includes service information, the ambient IoT device needs to carry a second format indicator in the data frame to indicate the information length of the service information.

[0634] Step S6204: The environmental Internet of Things device generates a data frame to be reported.

[0635] Step S6205: The environmental IoT device sends the data frame under the stimulation of the radio frequency signal.

[0636] The information indication method involved in the embodiment of the present disclosure may include at least one of steps S6201 to S6205. For example, steps S6202 to S6205 may be implemented as independent embodiments, but are not limited thereto.

[0637] In some embodiments, step S6201 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that the ambient IoT device can independently determine the format of the data frame for sending information without the need for the network device to determine it.

[0638] In the embodiments of the present disclosure, 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 of other embodiments.

[0639] Example 1: An ambient IoT device determines a data frame for reporting information; the information content carried by the data frame includes one of the following:

[0640] (1) Terminal index number;

[0641] (2) Terminal index number and service information;

[0642] (3) Terminal index number and control information;

[0643] (4) Service information;

[0644] (5) Control information;

[0645] (6) Terminal index number, service information and control information;

[0646] (7) Service information and control information.

[0647] It should be noted that the service information is the application data information of the ambient IoT device. For example, the service information is the historical measurement data of the sensor bound to the ambient IoT device, such as temperature, humidity, speed, concentration of the substance to be sampled, etc.

[0648] The control information is the execution response information of the ambient IoT device to the command on the network side.

[0649] Embodiment 2: Based on embodiment 1, the data frame further includes: a format indicator, which is used to indicate the information contained in the data frame.

[0650] The format indicators may include:

[0651] (1) first format indicator;

[0652] The first format indicator is used to indicate at least one of the following:

[0653] Indicates whether a terminal index number exists;

[0654] Indicates the terminal index type;

[0655] Indicates the terminal index length.

[0656] It should be noted that terminal index types may include, but are not limited to, EPC codes, ISO / IEC codes, or UID codes. Different types of terminal index numbers may have different index lengths. For specific terminal index types, such as EPC-coded terminal index numbers, index lengths may also vary. For example, the index lengths of EPC-coded terminal index numbers may vary, such as 96 bits, 256 bits, and so on.

[0657] (2) a second format indicator;

[0658] The second format indicator is used to indicate at least one of the following:

[0659] Indicates whether service information exists;

[0660] Indicates the number of bits of service information.

[0661] It should be noted that the bit amount of service information refers to the number of bits of the service information.

[0662] (3) a third format indicator;

[0663] The third format indicator is used to indicate at least one of the following:

[0664] Indicates whether control information exists;

[0665] Indicates the format of the control information.

[0666] It should be noted that the formats of the control information may include: Format 1: carrying only ACK information or only NACK information; Format 2: carrying ACK information, or carrying NACK information and failure reasons.

[0667] Example 3: Based on Example 2, the ambient IoT device determines the data frame of the reported information by itself and indicates the selected data frame format in the format indicator.

[0668] Embodiment 4: Based on embodiment 3, the format indicator is located before the information content contained in the data frame, and the format indicator is not jointly encoded with the information content, that is, the decoding of the format indicator can be independent of the decoding of the information content contained in the data frame.

[0669] Example 5: Based on Example 1, the ambient IoT device can determine the format of the data frame of the reported information according to the instruction of the network side.

[0670] It should be noted that, in this case, the information content included in the data frame is specified by the network side.

[0671] In the case where the network side specifies the format of the data frame, the data frame may not carry the format indicator, or the data frame may carry a partial format indicator.

[0672] Here, whether the data frame carries a format indicator, and which format indicators it carries, depends on the information content contained in the data frame specified by the network side.

[0673] For example, when the network side specifies that the data frame contains a terminal index number, the ambient IoT device needs to carry a first format indicator in the data frame to indicate the terminal index type and index length.

[0674] For another example, when the network side indicates that the data frame contains service information, the ambient IoT device needs to carry a second format indicator in the data frame to indicate the bit quantity of the service information.
