[0051] In order to facilitate understanding of the embodiments of the present application, the following contents are first described.
[0052] The power consumption of the transmitter is the key factor affecting the power consumption of low-power communication systems. According to the technical classification of low-power transmission technology, low-power communication transmission technology can be divided into passive low-power communication transmission technology and active low-power communication transmission technology. Among them, passive low-power communication transmission technology is backscatter communication technology. The transmitter itself does not generate a carrier, but modulates the information to be modulated onto the radio frequency carrier sent by a third-party device. Therefore, high-power radio frequency devices such as carrier generation modules and phase-locked loops are not required, thereby achieving low-power communication. Active low-power communication transmission technology, although it needs to generate an radio frequency carrier itself, can achieve low-power transmission through a low-power modulation structure.
[0053] Backscatter Communication (BSC) refers to a type of passive IoT device that uses radio frequency signals from other devices or the environment to modulate signals and transmit information. The basic building blocks and main functions of a backscatter communication transmitter include:
[0054] -Antenna unit: used to receive RF signals and control commands, and also used to send modulated backscattered signals.
[0055] Energy harvesting module or power supply module: This module is used by the backscatter communication device to harvest RF energy or other energy sources, including but not limited to solar energy, kinetic energy, mechanical energy, and thermal energy. In addition to the energy harvesting module, a battery power supply module may also be included, making the backscatter communication device semi-passive. The energy harvesting module or power supply module provides power to all other modules in the device.
[0056] -Microcontroller: includes control of baseband signal processing, energy storage or data scheduling status, switch switching, system synchronization, etc.
[0057] -Signal receiving module: used to demodulate control commands or data sent by the backscatter communication receiving end or other network nodes.
[0058] -Channel coding and modulation module: performs channel coding and signal modulation under the control of the controller, and realizes modulation by selecting different load impedances under the control of the controller through the selection switch.
[0059] -Memory or sensor module: used to store device identification information, location information or sensor data, etc.
[0060] In addition to the typical components mentioned above, future backscatter communication transmitters can also integrate tunnel diode amplifier modules, low-noise amplifier modules, etc. to improve the receiving sensitivity and transmission power of the transmitter.
[0061] Optionally, the basic building blocks and main functions of the backscatter communication receiving end include:
[0062] -Antenna unit: used to receive the modulated backscattered signal.
[0063] - Backscatter signal detection module: used to detect the backscatter signal sent by the backscatter communication transmitter, including but not limited to amplitude shift keying (ASK) detection, phase shift keying (PSK) detection, frequency shift keying (FSK) detection or quadrature amplitude modulation (QAM) detection, etc.
[0064] -Demodulation and decoding module: demodulates and decodes the detected signal to restore the original information stream.
[0065] In one implementation, tags can be categorized into the following types based on their capabilities and source:
[0066] -C1 / C2 tags: Passive tags, which receive energy from electromagnetic waves sent by the RFID reader and can only send data after being activated;
[0067] -C3 tag: A semi-passive tag uses its own battery and other energy sources only for the circuit in the RFID tag. It does not actively send data signals to the outside. It only sends data signals when it is activated by electromagnetic waves sent by the RFID reader.
[0068] -C4 tag: Active tag, which actively sends data by relying on its own battery or other energy source.
[0069] In another implementation, tags can be divided into:
[0070] Device A: This is a passive tag with no energy storage capacitor or battery. It relies on radio frequency (RF) signals for power. The received RF signal serves as the power supply for the rectifier. It does not have carrier generation capability and has the lowest power consumption.
[0071] -Device B: The tag is a semi-passive tag with an energy storage capacitor / battery and relies on non-RF signals for power. It may also have a PA / LNA or other active components but does not have carrier generation capability. Its power consumption is secondary.
[0072] -Device C: This is an active tag with a capacitor / battery for energy storage. It relies on non-RF signals for power supply and has carrier generation capability. It consumes the most power.
[0073] The above-mentioned tags usually only have one working mode, namely passive, semi-passive or active working mode, which limits the flexibility of the tag's use. For example, in a perception business scenario, when taking inventory of tags, a low-power and low-complexity passive working mode can be used; however, if the tag still reports perception data in a passive working mode, when the data volume is large, communication failure may occur due to insufficient power supply. Therefore, in order to improve transmission reliability and coverage, a tag integrating two communication modes, such as integrating passive communication mode and active communication mode, or integrating active communication mode and passive communication mode, is another important type of low-power tag option.
[0074] Optionally, the solution in this application can be applied to LTE systems, 5G NR systems and NR evolution systems, such as 6G systems and 6G evolution systems, as well as IEEE 802.11 systems (such as WiFi systems), Bluetooth systems, LoRa systems, Zigbee systems, satellite communication systems, wireless optical communication systems, backscatter communication systems, low-power Internet of Things systems, etc.
[0075] The information processing method, apparatus, communication device, and readable storage medium provided by the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.
[0076] Please refer to FIG. 2 , which is a flowchart of an information processing method provided in an embodiment of the present application. The method is executed by a first device. As shown in FIG. 2 , the method includes the following steps:
[0077] Step 21: The first device obtains first information;
[0078] Step 22: The first device determines or executes a first action according to the first information.
[0079] In the embodiments of the present application, the first device may be a hybrid tag, etc., which can effectively achieve a trade-off between communication coverage and power consumption by switching between active and passive communication modes. For example, when supporting short-range communication, it can reduce communication power consumption by operating in passive communication mode; or when supporting long-range communication, it can ensure communication coverage by operating in active communication mode.
[0080] Optionally, the first behavior includes at least one of the following:
[0081] The first device operates only in an active communication mode; for example, the first device autonomously generates a carrier wave for communication;
[0082] The first device operates only in a passive communication mode; for example, the first device operates only in a backscatter communication mode, that is, the first device does not generate a carrier, but performs backscatter communication based on a radio frequency carrier signal sent by another device;
[0083] The first device operates in both an active communication mode and a passive communication mode; for example, the first device supports both autonomous generation of a carrier for communication and backscatter communication based on a radio frequency carrier signal transmitted by another device without generating a carrier;
[0084] The first device is in a dormant state or a non-sending state.
[0085] Thus, it is possible to configure or schedule a first device that integrates active and passive communication modes, thereby enabling communication mode switching and transmission parameter adjustment in different scenarios to meet different communication performance (such as communication rate, communication distance, etc.) and power consumption requirements. Furthermore, when the solution in this application is applied to hybrid tags, unified management and scheduling of hybrid tags can be achieved.
[0086] Optionally, the information processing method in this embodiment further includes:

[0092] whether the first device is supported to perform mode switching, or whether the first device is supported to operate in an active communication mode and a passive communication mode simultaneously; for example, a communication mode activation or deactivation configuration may be performed to configure whether the first device is supported to perform mode switching, or whether the first device is supported to operate in an active communication mode and a passive communication mode simultaneously;
[0093] Whether to allow the first device to report request information or auxiliary information for switching the working mode; for example, a relevant switch can be configured to configure whether to allow the first device to report request information or auxiliary information for switching the working mode, optionally including request information or auxiliary information of transmission parameters related to the communication mode;

[0095] Optionally, the communication mode of the first device includes at least one of the following:

[0098] Active and passive communication modes operate in parallel; for example, the first device supports both autonomous carrier generation for communication and backscatter communication based on RF carrier signals sent by other devices without generating a carrier;

[0100] Optionally, the first transmission parameter of the first device is specific to a certain communication mode, including but not limited to at least one of the following:

[0102] The encoding mode of the first device includes at least one of the following: channel coding and line coding. For example, the encoding mode may be line coding such as pulse interval encoding (PIE), bi-phase space coding (FMO), and Miller supported by the passive communication mode, or channel coding modes such as polar code, convolutional code, and RS code supported by the active communication mode. Alternatively, the encoding mode may be a channel coding mode such as convolutional code supported by the passive communication mode, or a channel coding mode such as polar code supported by the active communication mode. The two communication modes support different channel coding modes. In this case, the first device may parse the communication mode corresponding to the required operation according to the configured or indicated encoding mode.
[0103] The first type of parameters are transmission parameters supported in both active and passive communication modes but using different types of parameters, including but not limited to: signal waveform, pulse shaping method, preamble type, bit interleaving method, scrambling method, precoding method, etc.;
[0104] The second type of parameters are transmission parameters specific to the active communication mode or the passive communication mode; for example, the reflection coefficient is specific to the passive communication mode, and the transmit power or power level is specific to the active communication mode; other transmission parameters specific to the passive communication mode include but are not limited to energy storage parameters, etc. In this case, the first device can parse the communication mode corresponding to the required operation based on the signal parameters of the configured or indicated specific operating mode;
[0105] The third type of parameters, the third type of parameters are transmission parameters corresponding to a predefined or preconfigured communication mode, or the third type of parameters are transmission parameters corresponding to a predefined or preconfigured communication parameter table; for example, the third type of parameters can be 1 parameter or 1 group of parameters; the predefined / preconfigured communication mode or communication parameter table can correspond to the specific communication mode and communication parameters by means of an index, and the first device only needs to parse one or more transmission parameters under the index to parse out the corresponding communication mode and all other transmission parameters.
[0106] Optionally, the second transmission parameter of the first device is decoupled from the communication mode, that is, the first device cannot parse the required communication mode from these configured or indicated parameters. The second transmission parameter may include but is not limited to at least one of the following:

For example, the communication mode switching conditions include but are not limited to: 1) when just joining the network or waking up from a long-term dormant state, entering the active communication mode or the passive communication mode; 2) if the battery level in the active communication mode is lower than the preset threshold, or the signal quality exceeds the preset threshold, or the size of the transmitted message content is lower than the preset threshold, then switch from the active communication mode to the passive communication mode; 3) if the number of transmission failures in the active communication mode exceeds the preset threshold, or the signal quality is lower than the preset threshold, or the size of the transmitted message content is lower than the preset threshold, then switch to the active and passive communication modes to work simultaneously; 4) if the size of the transmitted message content in the active and passive communication modes is lower than a certain threshold, or the battery level is lower than a certain threshold, or the number of transmission failures in the active communication mode is higher than the preset threshold, or the signal quality in the active communication mode is lower than a certain threshold, then switch to the passive communication mode; and so on.
[0114] Optionally, in addition to being configured or indicated, the above-mentioned communication mode switching condition may also be predefined or agreed upon by a protocol, and this is not limited.
[0115] A first device switches from a first communication mode to a second communication mode; wherein the first communication mode and the second communication mode satisfy at least one of the following:
[0116] (1) The first communication mode is an active communication mode, and the second communication mode is any one of the following: a passive communication mode, a mode in which the active and passive communication modes are operated in parallel, a dormant state mode, or a non-sending state mode;
[0117] (2) the first communication mode is a passive communication mode, and the second communication mode is any one of the following: an active communication mode, a mode in which the active communication mode and the passive communication mode are operated in parallel, a dormant state mode, or a non-sending state mode;
[0118] (3) the first communication mode is a parallel operation mode of an active communication mode and a passive communication mode, and the second communication mode is any one of the following: an active communication mode, a passive communication mode, a dormant state mode, or a non-sending state mode;
[0119] (4) the first communication mode is a dormant state mode or a non-sending state mode, and the second communication mode is any one of the following: an active communication mode, a passive communication mode, or a mode operating in parallel with the active communication mode and the passive communication mode;
[0120] (5) The first communication mode and the second communication mode are the same communication mode, such as an active communication mode or a passive communication mode, but have different transmission parameters.
[0121] For example, the executing the first action may include at least one of the following:
[0122] (a) The first device switches from a dormant, powered-off, or non-transmitting state to an active communication mode. For example, when the first device has just joined the network or awakened from a long-term dormant state, the network or system configuration defaults to active communication mode to ensure communication performance.
[0123] (b) The first device switches from a dormant, powered-off, or non-transmitting state to a passive communication mode. For example, when the first device has just joined the network or awakened from a long-term dormant state, the network or system configuration defaults to the passive communication mode to minimize device power consumption.
[0124] (c) The first device switches from a dormant, powered-off, or non-transmitting state to a state where both active and passive communication modes operate simultaneously. For example, when the first device is newly connected to the network or awakened from a long-term dormant state, the network or system configuration defaults to active and passive communication modes to ensure optimal communication performance.
[0125] (d) The first device switches from the active communication mode to the passive communication mode. For example, if the battery level of the first device in the active communication mode is lower than a preset threshold, or the signal quality exceeds a preset threshold, or the size of the transmitted message is lower than a preset threshold, the first device switches from the active communication mode to the passive communication mode to reduce device power consumption.
[0126] (e) The first device switches from the active communication mode to the simultaneous active and passive communication modes. For example, if the number of transmission failures in the active communication mode exceeds a preset threshold, or the signal quality falls below a preset threshold, or the size of the transmitted message falls below a preset threshold, the first device switches to the simultaneous active and passive communication modes to further improve communication performance.
[0127] (f) The first device switches from a passive communication mode to an active communication mode. For example, if the number of transmission failures in the passive communication mode exceeds a preset threshold, or the signal quality falls below a preset threshold, or the size of the transmitted message exceeds a preset threshold, the first device switches to the active communication mode to further improve communication performance.
[0128] (g) The first device switches from a passive communication mode to a state in which both active and passive communication modes operate simultaneously. For example, if the number of transmission failures in the passive communication mode exceeds a preset threshold, or the signal quality falls below a preset threshold, or the size of the transmitted message exceeds a preset threshold, the first device switches to a state in which both active and passive communication modes operate simultaneously to further improve communication performance.
[0129] (h) The first device switches from an active communication mode and a passive communication mode in parallel to a passive communication mode. For example, if the size of the information content transmitted by the first device in the active communication mode and the passive communication mode in parallel is lower than a certain threshold, or the battery level is lower than a certain threshold, or the number of transmission failures in the active communication mode is higher than a preset threshold, or the signal quality in the active communication mode is lower than a certain threshold, then the device switches to the passive communication mode.
[0130] (i) The first device switches from an active communication mode and a passive communication mode in parallel to an active communication mode. For example, if the size of the information content transmitted by the first device in the active communication mode and the passive communication mode in parallel is lower than a certain threshold, or the battery level is lower than a certain threshold, or the number of transmission failures in the passive communication mode is higher than a preset threshold, or the signal quality in the passive communication mode is lower than a certain threshold, the first device switches to the active communication mode.
[0131] (j) The first device switches from a passive communication mode, an active communication mode, or a state in which both the active and passive communication modes are operating, to a sleep state. For example, the first device enters the sleep state if it does not receive scheduling information within a configured time; or the first device enters the sleep state from its current operating mode if it receives sleep indication information.
[0132] (k) The first device switches from being in a passive communication mode, or being in an active communication mode, or being in a state where both the active and passive communication modes are working simultaneously, to different transmission parameters in the same mode.
[0133] In the embodiment of the present application, the obtaining of the first information may include:

[0185] For example, the carrying manner of the first information may include at least one of the following:

[0187] (b) via MACCE bearer; for example, similar to the use of MACCE signaling in a discontinuous reception (DRX) mechanism to configure the communication state or transmission parameters of the first device, this situation is also applicable to the first device that does not support RRC signaling or has a weak NAS signaling capability;

[0189] (d) Carried by factory configuration information or default configuration information; for example, when the first device accesses the network for the first time or does not support RRC configuration information, the system sets the corresponding default communication mode or transmission parameters.
[0190] It should be noted that the various signalings described above can exist simultaneously, and the final communication mode or transmission parameters are determined based on priority. For example, the first device supports both RRC configuration and dynamic indications based on DCI, SCI, or physical layer (L1) signaling. After entering the network, the first device continues to communicate using the communication mode and transmission parameters configured by RRC until it receives DCI, SCI, or physical layer (L1) signaling that changes the communication mode or transmission parameters, at which point it switches to the corresponding communication mode or transmission parameters.

[0195] Optionally, the third device may be a device different from the second device, that is, the second device that performs configuration or instruction at this time is a different device from the third device that receives the signal from the first device.
[0196] Optionally, the third device and the second device may also be the same device, that is, the second device that performs configuration or instruction at this time is the same device as the third device that receives the signal of the first device.

[0254] (b) via MACCE bearer; for example, similar to using MACCE signaling to configure the communication state or transmission parameters of the first device in a discontinuous reception (DRX) mechanism, this situation is also applicable to the first device that does not support RRC signaling or has a weak NAS signaling capability;

[0256] (d) Carried by factory configuration information or default configuration information; for example, when the first device accesses the network for the first time or does not support RRC configuration information, the system sets the corresponding default communication mode or transmission parameters.
[0257] The present application is described below with reference to specific embodiments.
[0258] Example 1
[0259] In the first embodiment, the first device (eg, a hybrid tag device) determines a communication mode and corresponding transmission parameters through network configuration information or system configuration information.
[0260] In one possible scenario, for a first device that has previously accessed a network, the first device retains some network configuration information and uses the communication mode and transmission parameters corresponding to the configuration information for communication the next time it accesses the network. For example, for a first device that supports the RRC protocol or the NAS protocol, before the first device enters sleep or shuts down, it still retains the network configuration information regarding the default communication mode and transmission parameters for this access or the first access to the network; when the first device wakes up or turns on to access the network the next time, it can use the default communication mode and transmission parameters configured in the network for communication.
[0261] In another possible scenario, when the first device leaves the factory, the manufacturer uses factory default settings to fix the default communication mode and transmission parameters of the first device. These factory default configuration parameters are stored in a fixed manner in the storage area of the first device, without the need for network configuration. This method is suitable for tag devices with weak network access capabilities and that do not support network system configuration information.
[0262] The above two methods are applicable to the communication transmission configuration when the first device communicates in a fixed scenario or when the first device just joins the network.
[0263] Example 2
[0264] In the first embodiment described above, the communication mode and corresponding transmission parameters are determined through network configuration information or system configuration information. This only addresses communication configuration in fixed scenarios or when the first device is newly connected to the network. However, in more scenarios, such as when the first device moves, the surrounding channel environment changes, the first device's transmission service changes, or the first device's status changes, the network needs to dynamically schedule or instruct the first device on the communication mode and transmission parameters.
[0265] In one possible scenario, the first device switches from an active communication mode to a passive communication mode. For example, if the battery level of the first device in the active communication mode falls below a preset threshold, or the signal quality exceeds a preset threshold, or the size of the transmitted message falls below a preset threshold, or the number of consecutive successful transmissions exceeds a preset threshold, the device switches from the active communication mode to the passive communication mode to reduce power consumption.
[0266] In one possible scenario, the first device switches from being in active communication mode to operating in both active and passive communication modes. For example, if the number of transmission failures in the active communication mode exceeds a preset threshold, or the signal quality falls below a preset threshold, or the size of the transmitted message falls below a preset threshold, the first device switches to operating in both active and passive communication modes to further improve communication performance.
[0267] In one possible scenario, the first device switches from a passive communication mode to an active communication mode. For example, if the number of transmission failures in the passive communication mode exceeds a preset threshold, or the signal quality falls below a preset threshold, or the size of the transmitted message exceeds a preset threshold, the first device switches to the active communication mode to further improve communication performance.
[0268] In one possible scenario, the first device switches from a passive communication mode to a state in which both active and passive communication modes operate simultaneously. For example, if the number of transmission failures in the passive communication mode exceeds a preset threshold, or the signal quality falls below a preset threshold, or the size of the transmitted message exceeds a preset threshold, the first device switches to a state in which both active and passive communication modes operate simultaneously to further improve communication performance.
[0269] In one possible scenario, the first device switches from being in both active and passive communication modes to being in passive communication mode. For example, if the size of the information content transmitted by the first device in both active and passive communication modes falls below a certain threshold, or the battery level falls below a certain threshold, or the number of transmission failures in the active communication mode exceeds a preset threshold, or the signal quality in the active communication mode falls below a certain threshold, then the device switches to the passive communication mode.
[0270] In one possible scenario, the first device switches from being in both active and passive communication modes to being in active communication mode. For example, if the size of the information content transmitted by the first device in both active and passive communication modes falls below a certain threshold, or the battery level falls below a certain threshold, or the number of transmission failures in the passive communication mode exceeds a preset threshold, or the signal quality in the passive communication mode falls below a certain threshold, then the device switches to the active communication mode.
[0271] The advantage of this switching method is that the second device can flexibly schedule or instruct the communication mode and transmission parameters of the first device according to the current channel environment, the status of the first device, communication service requirements, communication quality statistics, etc., so that the first device can achieve a trade-off between communication performance and power consumption.
[0272] Example 3
[0273] In addition to the second device determining the communication mode and transmission parameters of the first device based on the information it obtains, since the first device is most aware of its own device status and the surrounding channel environment, the first device can first send auxiliary information or request information to the second device to request the communication mode and transmission parameters that the first device prefers or hopes to be configured; then, the second device combines the auxiliary information / request information and other parameters of the first device to configure or schedule the communication mode and transmission parameters of the first device.
[0274] In one possible solution, the first device sends its own status information or auxiliary information to the second device, including at least one of the following: power information of the first device, energy storage status information of the first device, overheating information of the first information, signal / channel measurement information of the first device in active communication mode, signal / channel measurement information of the first device in passive communication mode, quality of service (QoS) requirements of the service to be sent, etc.; then, the second device determines the communication mode and transmission parameters of the first device based on the auxiliary information sent by the first device, and in combination with the current resource allocation and interference conditions of the entire network system, and the statistically obtained signal quality conditions, etc., and configures or instructs them to the first device.
[0275] In another possible solution, the first device first determines the appropriate communication mode and transmission parameters based on its own status and parameters such as the QoS requirements of the service to be sent, and sends request information for the communication mode and transmission parameters that it prefers to work or that it hopes to configure to the second device; then, the second device finally determines the communication mode and transmission parameters of the first device based on the request information sent by the first device and in combination with the current resource allocation and interference conditions of the entire network system, as well as the statistically obtained signal quality conditions, and configures or instructs the first device.
[0276] For example, the first device requests the second device to switch from the active communication mode to the passive communication mode based on its own energy saving or energy storage situation. The possible process includes:
[0277] S1: The second device first configures the communication mode switch, that is, whether to allow the first device to report the working mode or transmission parameter request related to the communication mode;
[0278] S2: If reporting is allowed, the first device reports a request for a passive communication mode; optionally, the request information may further include transmission parameters in the passive communication mode;
[0279] S3: Optionally, the second device configures or indicates the passive communication mode of the first device through the first information as above, or configures or indicates the passive communication mode and corresponding transmission parameters.
[0280] For another example, the first device requests the second device to switch from the passive communication mode to the active communication mode based on the signal quality or poor communication coverage calculated in the passive communication mode. The possible process includes:
[0281] S1: The second device first configures the communication mode switch, that is, whether to allow the first device to report the working mode or transmission parameter request related to the communication mode;
[0282] S2: If reporting is allowed, the first device reports a request for active communication mode; optionally, the request information may further include transmission parameters in passive communication mode;
[0283] S3: Optionally, the second device configures or indicates the active communication mode of the first device through the first information as above, or configures or indicates the active communication mode and corresponding transmission parameters.
[0284] Example 4
[0285] In this fourth embodiment, the first and third devices initially preset rules or switching conditions. As long as the first and third devices meet the preset rules or switching conditions during communication, the communication mode and transmission parameters are changed accordingly according to the preset rules / conditions, without requiring the second device to configure / schedule / instruct the first device's communication mode and transmission parameters. The preset rules or switching conditions for the first and third devices may also be network-configured or factory-set, which is not a limitation in this embodiment.
[0286] In a feasible solution, for example, the first device and the third device adaptively change the communication mode and transmission parameters according to the number of transmission failures or the number of ACK / NACKs, and the corresponding rules may be as follows (this is only an example):
[0287] (1) When the number of consecutive ACKs in the passive communication mode is greater than a preset number, such as 8, the first device continues to operate in the passive communication mode; when the number of NACKs in the passive communication mode is greater than a preset number, such as 3, the first device switches to the active communication mode;
[0288] (2) When the number of consecutive ACKs in the active communication mode is greater than a preset number, such as 8, the first device switches to the passive communication mode; when the number of consecutive NACKs in the active communication mode is greater than a preset number, such as 3, the first device switches to a state where the active communication mode and the passive communication mode work simultaneously;
[0289] (3) When the number of consecutive ACKs in the active communication mode and the passive communication mode is greater than a preset number, such as 8, the active communication mode is switched to; when the number of consecutive NACKs in the active communication mode and the passive communication mode is greater than a preset number, such as 3, the first device continues to maintain the current working mode or declares a link failure, and then initiates the subsequent random access process or re-network selection process.
[0290] In another feasible solution, the first device and the third device can adaptively change the communication mode and transmission parameters according to the communication signal quality (such as RSRP, RSSI, SNR, SINR, etc.). The corresponding rules are similar to the NACK / ACK solution and will not be repeated here.
[0291] In another feasible solution, the first device and the third device can adaptively change the communication mode and transmission parameters based on the transmission service type or service priority. If the first device decides to initiate active access, such as reporting some sensor alarm service data with high service priority, the active communication mode is changed to active mode.
[0292] In another feasible solution, during the communication between the first device and the third device, if there is still no network scheduling after a preset time window has expired, the behavior of the first device may be defined as follows (this is for example only):
[0293] (1) If the preset time window T1 is exceeded, the first device enters a passive communication mode, thereby saving device power consumption;
[0294] (2) If the preset time window T2 is exceeded, the first device enters a dormant state, thereby further saving the power consumption of the terminal.
[0295] It's worth noting that the aforementioned communication modes can also be mapped to a set of transmission parameters, further reducing network signaling overhead. This approach is suitable for tags with strong capabilities and some measurement or autonomous decision-making capabilities. The advantage is that communication modes can be switched adaptively based on pre-set rules without requiring network scheduling.

In the embodiment of the present application, the information processing device provided in the embodiment of the present application is described by taking the information processing device executing the information processing method as an example.

[0300] The first device operates only in active communication mode;
[0301] The first device only operates in a passive communication mode;
