[0136] With the rapid adoption of Internet of Things (IoT) technology across various industries, the large-scale deployment of IoT devices powered by traditional batteries is facing challenges, including environmental, cost, and energy conservation. This has led to limitations in some scenarios, hindering the demand and negatively impacting user experience. In some scenarios, the astronomical growth of IoT networks, coupled with the proliferation of IoT devices, has pushed network maintenance costs, including labor and battery costs, to new heights. Furthermore, billions of traditional batteries are discarded annually, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be challenging in extreme environmental conditions. Battery-free IoT (also known as passive IoT) communications have been proposed to improve network performance and sustainability, expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. By eliminating traditional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications.

[0137] In some embodiments, various low power wide area (LPWA) technologies, such as machine type communication (MTC), narrow band internet of things (NB-IoT), and reduced capability (RedCap) terminals, have been developed to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption, and large-scale connectivity, which can meet the requirements of many applications. However, there are still the following situations that need to be addressed: 1. In some scenarios (such as in extreme environmental conditions (e.g., high voltage, extremely high / low temperature, humid environment, etc.), devices powered by traditional batteries are not applicable. 2. Maintenance-free devices are required (e.g., devices that do not require replacement of traditional batteries). 3. Devices with ultra-low complexity, very small device size (e.g., millimeter (mm) thickness), and longer life cycle are required. In order to meet the above unmet needs, the Internet of Things that supports ambient energy is a very promising technology.

[0138] In some embodiments, an ambient-powered IoT device is a passive device powered by harvested energy. Such IoT devices are battery-free or have limited energy storage capabilities (e.g., using capacitors). In some embodiments, an ambient-powered IoT device can be powered by harvesting radio waves, light, motion, heat, or any other suitable power source to power wireless communications or data transmission.

[0139] In some embodiments, the above terms such as "ambient energy-enabled IoT device", "passive device", "passive IoT device", "ambient energy-based device", "ambient IoT device", "tag", etc. can be used interchangeably.

[0140] In some embodiments, IoT devices that support ambient energy (such as ambient IoT devices) can use the energy collected from the environment to drive themselves for data transmission and wireless communication. The current mainstream low-power IoT communication chips (such as low-power Bluetooth low energy (BLE) chips, long-range radio (LoRa) chips, and NB-IoT chips) have a transmit and receive power consumption of tens of milliwatts or even hundreds of milliwatts, while the energy collected from the environment is only in the microwatt level, which is unable to drive devices with the above-mentioned types of chips to work. Therefore, a new wireless communication technology is needed to reduce communication power consumption to tens of microwatts or even less than ten microwatts. To this end, backscatter (BS) communication technology can be used. Backscatter communication is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future IoT, and is an important means to achieve "intelligent connection of all things."

[0141] In some embodiments, backscatter communication utilizes the principle of backscattering of radio frequency signals to design a modulation and transmission technology with extremely low power consumption. As shown in FIG1B , FIG1B is a schematic diagram of wireless communication based on backscattering according to an embodiment of the present disclosure. The excitation source 11 sends a radio frequency signal to the environmental Internet of Things device 12. When the radio frequency signal reaches the environmental Internet of Things device 12, a part of it will be reflected, and the environmental Internet of Things device 12 can adjust the matching between the receiving antenna and the impedance according to the information to be sent to enhance the reflection of the above radio frequency signal, and modulate the information to be sent onto the backscattered signal for transmission. This process is similar to a reflector. Compared with other communication technologies, backscatter transmission does not require a complex radio frequency structure, reduces the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, high-precision filters, and does not require complex baseband processing. Therefore, it can simplify the design of the above-mentioned Internet of Things devices that support environmental energy and greatly reduce the cost of equipment.

[0142] In some embodiments, the radio frequency signal is used to provide energy for the environmental IoT device to transmit a signal. Therefore, the radio frequency signal can be referred to as an excitation signal or a trigger signal.

[0143] In some embodiments, the excitation source may be a reader of an ambient IoT device or an anchor point of the reader.

[0144] In some embodiments, when passive IoT technology is integrated into the communication system 100, the embodiments of the present disclosure may provide, but are not limited to, the following architectures of the communication system 100 (also referred to as an IoT system):

[0145] Architecture 1: As shown in FIG1C , FIG1C is a schematic diagram of an architecture of an IoT system according to an embodiment of the present disclosure. Uplink and / or downlink transmissions are directly performed between an environmental IoT device 12 and a network device 20 (eg, a base station).

[0146] Architecture 2: As shown in FIG1D , FIG1D is another schematic diagram of an IoT system architecture according to an embodiment of the present disclosure. Uplink and / or downlink transmissions are performed indirectly between the environmental IoT device 12 and the network device 20 (e.g., a base station) via an intermediate node 30 .

[0147] In some embodiments, the intermediate node 30 forwards uplink transmission and / or downlink transmission. Exemplarily, the intermediate node 30 may be a relay node, an integrated access backhaul (IAB) node, a terminal, a signal amplification node (repeater), etc.

[0148] Architecture 3: As shown in Figure 1E, which is another schematic diagram of an IoT system architecture according to an embodiment of the present disclosure, the environmental IoT device 12 and the network device 20 (e.g., an access network device) directly perform either uplink or downlink transmission, and indirectly perform the other of the uplink and downlink transmissions through the auxiliary node 40.

[0149] In some embodiments, the auxiliary node 40 forwards uplink transmission and / or downlink transmission. Exemplarily, the auxiliary node 40 may be a relay node, an integrated access backhaul (IAB) node, a terminal, a signal amplification node (repeater), etc.

[0150] Architecture 4: As shown in Figure 1F, Figure 1F is another schematic diagram of the architecture of an IoT system according to an embodiment of the present disclosure. Uplink and downlink transmissions are performed directly between the ambient IoT device 12 and the terminal 50. The terminal 50 is responsible for collecting data from the ambient IoT device 12 and forwarding the collected data to the network.

[0151] In some embodiments, when the Internet of Things system adopts the above-mentioned architecture one and architecture two for communication, the spectrum resources that can be used may include three deployment modes: in-band mode, guard-band mode, or stand alone mode. The in-band mode refers to the use of general uplink spectrum resources and / or downlink spectrum resources for transmission. The guard-band mode refers to the use of spectrum resources in the guard band between the general uplink spectrum and the downlink spectrum for transmission. The stand alone mode refers to the use of spectrum resources unrelated to the general transmission spectrum for transmission.

[0152] It should be noted that the above-mentioned terms such as "Internet of Things system", "radio frequency identification (RFID) system", "passive Internet of Things system", and "environmental Internet of Things system" can be used interchangeably.

[0153] In some embodiments, as shown in FIG1G , FIG1G is a schematic diagram illustrating different types of ambient IoT devices according to an embodiment of the present disclosure. The aforementioned ambient IoT devices can be, but are not limited to, divided into the following three types:

[0154] Type A: No energy storage and no independent signal generation / amplification, and transmission is based on backscattering.

[0155] Type B: has energy storage but no independent signal generation, and transmits based on backscattering. The energy stored in the ambient IoT device can be used to amplify the backscattered signal.

[0156] Type C: Has energy storage and independent signal generation, and uses active RF components for transmission.

[0157] In some cases, to support data transmission from passive devices, a device in the network needs to support at least one of the following functions:

[0158] The function as an energy source (ES) is only applicable to type B and type C devices;

[0159] The downlink transmission (DT) function sends indication information to the passive device, thereby triggering the uplink transmission of the passive device. It is only used for type A devices.

[0160] This continuous wave (CW) function is only available to Type A and Type B devices. Type A devices transmit uplink signals by backscattering CW. CW is also a type of ES, and Type A devices can receive and store CW energy.

[0161] The uplink receive (UR) function receives uplink information backscattered by passive devices, or receives uplink information actively transmitted by passive devices. It is only used for type A devices.

[0162] It should be noted that the device that performs the above-mentioned ES, DT, CW, UR and other functions may be a terminal, a repeater, a relay node or a network device.

[0163] In some embodiments, an Ambient IoT device may support only one of the above functions, or may support multiple of the above functions, or may support all of the above functions.

[0164] It's important to note that, according to the current Electronic Product Code (EPC) protocol, IoT systems are half-duplex. During a single transmission, only one reader (or IoT device, such as a tag) can transmit a signal. Therefore, the reader and IoT device never transmit simultaneously, and different IoT devices operate serially.

[0165] However, when integrating these passive IoT technologies into communication systems, concurrent communication becomes a concern. This means that multiple IoT devices can simultaneously perform one-to-one operations with the network, such as access commands. In this scenario, ensuring unique communication between IoT devices and the network becomes a pressing issue.

[0166] In order to solve the above problems, the embodiments of the present disclosure provide an information transmission method, a communication device, a communication equipment and a storage medium to ensure the uniqueness of communication between the environmental Internet of Things device and the network, thereby avoiding conflicts during the communication process between the environmental Internet of Things device and the network side, and further improving the reliability of communication between the environmental Internet of Things device and the network.

[0167] In some embodiments, the first device may be a passive device. In one example, the passive device may be an ambient IoT device.

[0168] In some embodiments, the second device may be an excitation source for the first device. In one example, the second device is a reader of an ambient IoT device.

[0169] In some embodiments, the second device may be a base station, an intermediate node or an auxiliary node, or a terminal.

[0170] In some embodiments, the first command may be a command sent by the second device to the first device during access to the first device. In one embodiment, the first command may be an access class command, also referred to as an access command.

[0171] In one example, the first command may be at least one of a random number request (Req_RN), read, write, kill, lock, access, block write, and block erase. It should be noted that in other communication processes between the first device and the second device, the first command may also be other commands, such as a select command, an inventory command, etc., which are not specifically limited in the embodiments of the present disclosure. It should be noted that the "command" described in the embodiments of the present disclosure may be replaced by terms such as "signaling," "signaling," "information," and "message." Of course, it may also be other transmission forms sent by the second device to the first device to perform a certain operation on the first device, which are not specifically limited in the embodiments of the present disclosure.

[0172] As shown in Figure 2, Figure 2 is an exemplary interaction diagram of an information transmission method according to an embodiment of the present disclosure. The embodiment of the present disclosure relates to an information transmission method, which is executed by the above-mentioned Internet of Things system. The above-mentioned information transmission method includes steps S201 to S207.

[0173] In some embodiments, the communication process between the first device and the second device may include, but is not limited to, the following three processes: a selection process, an inventory process, and an access process. In the disclosed embodiments, the information transmission method described above is described using the access process as an example. Of course, the information transmission method described above can also be applied to at least one of the selection process and the inventory process.

[0174] In some embodiments, before executing steps S201 to S207, the above-mentioned information transmission method further includes the following steps 1 to 5.

[0175] Step 1: The second device sends a selection command to at least one first device.

[0176] In some embodiments, the selection command may include a select command. Optionally, the selection command may also include a challenge command. After receiving the selection command, the first device is powered on. If the first device has been activated and remains activated for a period of time (e.g., 10 seconds) without being killed, then the first device is in a ready state.

[0177] For each first device, perform the following steps in sequence:

[0178] Step 2: The second device sends an inventory command to the first device.

[0179] In some embodiments, inventory commands include query (Query), query adjustment (QueryAdjust), query repeat (QueryRep), positive acknowledgement (ACK), and negative acknowledgement (NAK).

[0180] In some embodiments, the Query command carries a parameter Q. In one example, the value of the parameter Q is 0 to 15.

[0181] In some embodiments, upon receiving a valid Query command, the first device generates a random number based on parameter Q, which is used to set a slot counter. If the slot counter is 0, the first device executes step 3. If the slot counter is non-zero, the first device enters an arbitrate state and waits for the second device to send a QueryAdjust command or a QueryRep command.

[0182] In some embodiments, upon receiving a valid QueryAdjust command, the first device regenerates a random number based on parameter Q and uses the newly generated random number to set a slot counter. If the slot counter is 0, the first device proceeds to step 3. Otherwise, the first device remains in arbitration mode and waits for the second device to send a new QueryAdjust command or QueryRep command.

[0183] In some embodiments, upon receiving a valid QueryRep command, the first device decrements the random number generated based on the parameter Q, i.e., decrements the value of the slot counter by one. If the value of the slot counter is 0, the first device executes step 3. Otherwise, the first device remains in the arbitration state and waits for the second device to send a new QueryAdjust command or QueryRep command.

[0184] It should be noted that the random number generated according to the parameter Q can be a 16-bit random number with a value between 0 and 2. Q-1.

[0185] Based on this, through at least one of the Query command, the QueryAdjust command, and the QueryRep command, the value of the time slot counter of the first device is set to 0. Next, the first device executes step three.

[0186] Step 3: The first device backscatters a random number (denoted as RN16) to the second device and switches to the reply state.

[0187] Step 4: The second device sends an ACK command carrying RN16.

[0188] In some embodiments, the second device generates an RN16 that is the same as the RN16 in step 3, and carries the RN16 in an ACK command to send. In this case, the ACK command carries the RN16.

[0189] Step 5: After receiving a valid ACK command, the first device backscatters the application data to the second device and enters an acknowledgment state.

[0190] In some embodiments, after receiving a valid ACK command carrying a correct RN16, the first device sends application data to the second device so that the second device can identify the first device. In one example, the application data may include protocol control (PC), EPC, and checksum (CRC).

[0191] In some embodiments, if the first device does not receive a valid ACK command or receives an ACK command but the ACK command carries an incorrect RN16, the first device returns to the arbitration state.

[0192] At this point, the selection process and inventory process are completed. Next, the IoT system may execute steps S201 to S207.

[0193] In step S201 , the second device sends command A.

[0194] In some embodiments, the first device receives command A. In this case, the first command is command A.

[0195] In some embodiments, the first device enters the open state from the acknowledged state after receiving command A. In some embodiments, if the access password is 0, the first device enters the secure state from the open state.

[0196] In some embodiments, command A carries first information configured by the second device for the first device. The first information can be used to identify the communication between the second device and the first device.

[0197] In some embodiments, the name of the first information is not limited, and may be, for example, a handle, identification information, an identification bit, an identification, etc.

[0198] In some embodiments, when a second device needs to access multiple first devices simultaneously, to avoid conflicts, the second device can configure corresponding first information for different first devices to identify the communication between the second device and the different first devices. In one embodiment, the second device identifies the communication between different first devices by configuring different first information for different first devices. In one example, the first information configured by the second device for first device A is a, and the first information configured by the second device for first device B is b, where a≠b.

[0199] In some embodiments, the phrase "first information is used to identify the communication between the second device and the first device" can also be understood as: the first information is used to identify the communication link (or communication transmission) between the second device and a specific first device, or the first information can be used to identify a command and command response transmitted between the second device and a specific first device. In this case, the second device can identify which first device the command response originated from by receiving the first information carried in the command response, thereby distinguishing between communication transmissions between different first and second devices.

[0200] In some embodiments, the first information may be information configured by the second device for the first device. In one embodiment, the first information may be a numerical value configured by the second device for the first device, such as an index value, an identification value, etc. In one embodiment, the first information may also be a random number configured by the second device for the first device. In one example, the second device may generate the first information for the first device based on the parameter Q. In one example, the second device may generate the first information for the first device using a random number generator based on the electronic product code of the first device. In one example, the second device may determine the random number generated by the first device during the inventory process as the first information. Of course, the first information may also be generated by other means, which is not specifically limited in the embodiments of the present disclosure.

[0201] In some embodiments, command A can be a random number request (e.g., Req_RN). Of course, in other communication processes between the first device and the second device, command A can also be other commands, such as inventory commands, which are not specifically limited in the embodiments of the present disclosure. In one example, Req_RN can trigger the first device to enter the open state from the confirmed state. In another example, Req_RN can also trigger the first device to enter the secure state from the open state.

[0202] In some embodiments, while executing step S201 or after executing step S201, the second device may further transmit third information, where the third information is used to indicate the first duration. In one embodiment, the first duration is the duration during which the first information is valid. In one embodiment, the first duration is the duration during which the first information remains valid. In one embodiment, the first duration is the validity duration of the first information. In this case, the first information is valid within the first duration and invalid beyond the first duration.

[0203] In some embodiments, the third information may be carried in the aforementioned command A and sent to the first device to indicate the first duration to the first device. In one embodiment, the first information and the third information may be carried in different fields of command A and sent. In this case, the first device receives command A to obtain the first information and the third information.

[0204] In some embodiments, the third information may also be carried in other commands and sent to the first device. In one example, the other commands may be inventory commands, access commands, and the like.

[0205] In some embodiments, command A carrying the first information and other commands carrying the third information can be sent simultaneously, such as in the same time slot. In some embodiments, command A carrying the first information and other commands carrying the third information can also be sent in different time slots.

[0206] In some embodiments, after receiving the third information, the first device may start a first timer, where the duration of the first timer is the first duration. The first information is valid while the first timer is running, and becomes invalid when the first timer times out. After the first information expires, the first device releases the first information.

[0207] In some embodiments, after the first information becomes invalid, the second device may reconfigure the first information for the first device to identify subsequent communications.

[0208] In step S202, the first device sends a command response A.

[0209] In some embodiments, the second device receives command response A. In this case, the command response to the first command is command response A.

[0210] In some embodiments, the second information is carried in the command response A. In one embodiment, when the command A is a random number request (Req_RN), the second information can be used to indicate that the first information is valid.

[0211] In one example, the second information may be the same as the first information. After the first device receives command A, if the first device determines to use the first information (e.g., the first information is valid), the first device may send a command response A carrying the first information to the second device to confirm the first information and indicate that the first information is valid. Conversely, if the first device determines not to use the first information (e.g., the first information is invalid), the first device may omit step S202 and thus not respond to command A. In another example, the second information may be different from the first information. After the first device receives command A, if the first device determines to use the first information (e.g., the first information is valid), the first device may send a command response A carrying the second information to the second device to confirm the first information and indicate that the first information is valid. Conversely, if the first device determines not to use the first information (e.g., the first information is invalid), the first device may omit step S202 and thus not respond to command A. In this case, the second information can be understood as a response or acknowledgment of the first information. For example, the second information is a first value, indicating confirmation of the first information. Of course, the second information may also be implemented in other ways, which is not specifically limited in the embodiments of the present disclosure.

[0212] In step S203, the second device sends command B.

[0213] In some embodiments, the first device receives command B. In this case, the first command is command B.

[0214] In some embodiments, the first device is in an open state or a secured state.

[0215] In some embodiments, command B carries the above-mentioned first information to identify the communication between the second device and the first device.

[0216] In some embodiments, command B can be at least one of read, write, kill, lock, access, block write, and block erase. Of course, in other communication processes between the first device and the second device, command B can also be other commands, such as inventory commands, which are not specifically limited in the embodiments of the present disclosure.

[0217] In step S204, the first device sends a command response B.

[0218] In some embodiments, the second device receives command response B. In this case, the command response to the first command is command response B.

[0219] In some embodiments, the first information is valid within the first duration. Then, command response B may carry second information, which may be a response or acknowledgment of the first information. In one embodiment, the second information includes at least the first information.

[0220] In one example, when command B is a read command and carries first information, the first device sends command response B to the second device. Command response B includes second information. In this case, the second information includes the content of the block requested by command B and the second information. In some embodiments, if the first device fails to read or the first information is invalid, the first device may also send an error value to indicate the error and the cause of the error to the second device.

[0221] In one example, if command B is a write command and carries first information, after the write is successful, the first device sends command response B to the second device. Command response B includes second information, and in this case, the second information is the same as the first information. In some embodiments, if the write fails on the first device or the first information is invalid, the first device may also send an error value to indicate the error and the cause of the error to the second device.

[0222] In one example, if command B is a kill command and carries a kill password and first information, after the kill is successful, the first device sends command response B to the second device. Command response B includes second information, and in this case, the second information is the same as the first information. In some embodiments, if the first device fails to kill, the kill password is incorrect, the kill password is invalid, or the first information is invalid, the first device may also send an error value to indicate the error and the cause of the error to the second device.

[0223] In one example, if command B is a lock command and carries the first information, after the first device successfully locks, it sends command response B to the second device. Command response B includes the second information, which is identical to the first information. In some embodiments, if the first device fails to lock, the first information is invalid, etc., the first device may also send an error value to indicate the error and the cause of the error to the second device.

[0224] In one example, if command B is an access command and carries an access password and first information, and the access password is correct, the first device sends command response B to the second device, where command response B includes second information. In this case, the second information is identical to the first information. In some embodiments, if the first device fails to access the device, the access password is incorrect, the access password is invalid, the first information is invalid, etc., the first device may also send an error value to indicate the error and the cause of the error to the second device.

[0225] In one example, if command B is a block write and carries first information, after the block write is successful, the first device sends command response B to the second device. Command response B includes second information, and in this case, the second information is identical to the first information. In some embodiments, if the block write fails on the first device or the first information is invalid, the first device may also send an error value to indicate the error and the cause of the error to the second device.

[0226] In one example, if command B is a block erase and carries first information, after the block erase is successful, the first device sends command response B to the second device. Command response B includes second information, and in this case, the second information is the same as the first information. In some embodiments, if the block erase fails on the first device or the first information is invalid, the first device may also send an error value to indicate the error and the cause of the error to the second device.

[0227] In some embodiments, the second device may perform one or more operations on the first device. Then, steps S203 to S204 may be performed once or repeatedly performed multiple times to achieve communication between the second device and the first device.

[0228] In some embodiments, during the communication process between the second device and the first device, the second device may have exceeded the first duration by the time it executes step S203. In this case, the first message becomes invalid. In this case, the first device may refuse to receive subsequent command B sent by the second device. Alternatively, the first device may receive subsequent command B sent by the second device but confirm that command B is invalid. In this case, the first device does not respond to command B sent by the second device.

[0229] In some embodiments, after steps S203 to S204 are performed once or repeatedly, the second device may send command C to the first device to instruct the first device to release the first information. In this case, command C is a second command. In this case, after receiving command C, the first device releases the first information. Thereafter, the first device may refuse to receive command B subsequently sent by the second device, or may receive command B subsequently sent by the second device but determine that command B is invalid. In this case, the first device does not respond to command B sent by the second device.

[0230] In some embodiments, during the communication between the first device and the second device, the second device may also update the first information or reconfigure the first information for the first device to identify subsequent communications between the first device and the second device. Therefore, after steps S201 to S202, steps S205 to S207 may also be performed.

[0231] In step S205 , command D is sent.

[0232] In some embodiments, the first device receives command D. In this case, command D is a third command. In one embodiment, command D can be an inventory command, an access command, or the like. In one example, command D can be Query, QueryAdjust, QueryRep, ACK, or the like. In another example, command D can be Req_RN.

[0233] In some embodiments, command D is used to instruct the first device to update the first information.

[0234] In some embodiments, command D carries new first information configured by the second device for the first device (which may be recorded as fourth information). The fourth information may be used to identify the communication between the second device and the first device during subsequent communication between the second device and the first device.

[0235] In some embodiments, the second device may configure new first information for the first device in a secure state.

[0236] In some embodiments, when the first information is valid, the second device may configure fourth information for the first device and instruct the second device to use the fourth information to update the first information, so that in subsequent communication processes, the first device can carry the fourth information in the command response sent to the second device to identify the communication between the second device and the first device.

[0237] In some embodiments, when the second device configures the fourth information for the first device, the second device may also configure the validity period of the fourth information for the first device (which may be recorded as the second duration) and indicate this to the first device through new third information (which may be recorded as the fifth information). In one embodiment, the second duration is the validity period of the fourth information. In one embodiment, the second duration is the duration during which the fourth information remains valid. In one embodiment, the second duration is the validity period of the fourth information. In this case, the fourth information is valid within the second duration and is invalid beyond the second duration.

[0238] In some embodiments, command D may also carry fifth information. After receiving the fifth information, the first device may determine the second duration. In some embodiments, the fourth and fifth information may be carried in command D and sent to the first device to indicate the fourth information and the corresponding second duration. In one embodiment, the fourth and fifth information may be carried in different fields of command D. In this case, the first device receives command D to obtain the fourth information and the corresponding second duration.

[0239] In some embodiments, the second device may further send fifth information after step S205. In some embodiments, the fifth information may be carried in other commands sent by the second device after command D and sent to the first device. In one example, the other commands may be inventory commands, access commands, etc. after command D, which are not specifically limited in the embodiments of the present disclosure. At this time, the other command may also be the third command. In some embodiments, command D carrying the fourth information and other commands carrying the fifth information may be sent simultaneously, such as in the same time slot. In some embodiments, command D carrying the fourth information and other commands carrying the fifth information may also be sent separately in different time slots.

[0240] In some embodiments, if the first information remains valid, the second device may update or reconfigure the first information and the first duration for the first device. In this case, the second device may send the fourth information and the fifth information to the first device. In one example, command D may include the fourth information and the fifth information.

[0241] In some embodiments, when the first information remains valid, the second device may also update or reconfigure the first duration only for the first device. In this case, the second device may send the fifth information to the first device. In one example, command D may include the fifth information.

[0242] In some embodiments, when the above-mentioned first information remains valid and the second device updates or reconfigures the first duration for the first device, the first device can stop the above-mentioned first timer and start the second timer after receiving the fifth information, and the duration of the second timer is the second duration.

[0243] It should be noted that the fourth information mentioned above can also be described as the first information, the fifth information can also be described as the first duration, and the third command can also be described as the first command.

[0244] In step S206, the first device confirms that the fourth information is valid.

[0245] In some embodiments, after receiving command D, the first device updates the first information using the fourth information.

[0246] In some embodiments, after the first device receives command D, the first information becomes invalid immediately and the fourth information becomes valid immediately. In this case, the first device determines that the fourth information is valid and uses the fourth information for subsequent communication with the second device.

[0247] In some embodiments, when the second device configures the fourth and fifth information for the first device, after the fourth information takes effect, the first device communicates with the second device using the fourth information within a second duration. In some embodiments, outside the second duration, the first device may refuse to receive subsequent command B sent by the second device, or may receive subsequent command B sent by the second device but confirm that command B is invalid. In this case, the first device does not respond to command B sent by the second device.

[0248] In step S207, the first device sends a command response D.

[0249] In some embodiments, the second device receives command response D. In this case, the command response of the third command is command response D.

[0250] In some embodiments, command response D carries new second information (which may be recorded as sixth information). The sixth information may be used to indicate that the fourth information is effective.

[0251] In one example, the sixth information may be the same as the fourth information. After the first device receives command D, if the first device determines to use the fourth information, the first device may send a command response D carrying the sixth information to the second device. In this case, the sixth information is the same as the fourth information, thereby confirming the fourth information to the second device and indicating that the fourth information is effective. In another example, if the first device determines not to use the fourth information, the first device may omit step S207 and thus not respond to command D.

[0252] In one example, the sixth information may be different from the fourth information. After the first device receives command D, if the first device determines to use the fourth information, the first device may send a command response D carrying the sixth information to the second device. At this time, the sixth information is different from the fourth information and is used to indicate an affirmative response, thereby confirming the fourth information to the second device and indicating that the fourth information is effective. In one example, if the first device determines not to use the fourth information, the first device may omit step S207 and thus not respond to command D. In this case, the sixth information can be understood as the response information or response information of the fourth information, such as the sixth information is the first value, to indicate confirmation of the fourth information. Of course, the sixth information can also be implemented in other ways, and the embodiments of the present disclosure do not specifically limit this.

[0253] In some embodiments, at least one of command A, command B, and command D is a first command, and command C is a second command.

Alternatively, steps S205 to S207 can be performed during the execution of steps S203 to S204. Alternatively, steps S205 to S207 can be performed after one or more executions of steps S203 to S204. Of course, steps S205 to S207 can also be performed at other times, and this is not specifically limited in the present embodiment.

[0379] It should be noted that the following solution description is not limited to the above-mentioned improvement based on the RFID signaling process. The improvement based on the RFID signaling is only a feasible embodiment.

[0380] (1) The tag (i.e., the first device) receives signaling from the network side (which can be a base station or a UE, that is, a node with reader function, i.e., the second device). The signaling configures a Q. The tag generates at least a random value (such as RN16) based on the Q value and feeds back the RN16 to the network side.

[0381] (2) Tag (receives the ACK sent by the network side, which is used to confirm the receipt of the above RN16 and sends at least the EPC code to the network side.

[0382] (3) Tag receives the signaling sent by the network side. The signaling is used to configure a new RN16, which is recorded as a handle. Optionally, the network side can also configure a timer. The timer is used to control the validity range of the newly configured RN16, which is the handle. When the tag receives the timer configuration, it starts the timer. When the timer times out, the RN16 is released. When the tag receives the timer reconfiguration, it stops the original timer and starts the timer. Or the tag starts the timer after confirming the handle.

[0383] (4) Tag feedback handle, used to indicate that the handle is officially effective.

[0384] (5) The Tag receives a command from the network to release RN 16. From this point on, the Tag does not receive any access commands from the network, or considers any access commands invalid.

[0385] Solution 2: handle update.

[0386] (1) When a tag has a valid handle, the network can configure a new handle for the tag to update the handle, which is used to identify the tag in subsequent communications. If the tag receives a new handle, the original handle immediately becomes invalid and the new handle takes effect immediately. The tag replies to the network with the new handle to confirm the new handle is effective.
