[0002] In related technologies, a tag only supports one communication mode, that is, either a communication mode that actively generates a carrier or a passive backscatter communication mode.

[0049] To facilitate the understanding of the embodiments of the present application, the following content is first described.

[0050] The power consumption of the transmitter is the key to affecting the power consumption of the low-power communication system. According to the technical classification of low-power transmission technologies, low-power communication transmission technologies can be divided into passive low-power communication transmission technologies and active low-power communication transmission technologies. Among them, the passive low-power communication transmission technology is the backscatter communication technology. The transmitter itself does not generate a carrier, but modulates the information to be modulated onto the radio frequency carrier transmitted by a third-party device. Therefore, high-power radio frequency devices such as a carrier generation module and a phase-locked loop are not required, thereby achieving low-power communication. For the active low-power communication transmission technology, although it needs to generate a radio frequency carrier itself, low-power transmission can be achieved through a low-power modulation structure.

[0051] Backscatter Communication (BSC) refers to the backscatter communication device using radio frequency signals in other devices or the environment for signal modulation to transmit its own information, which is a relatively typical passive Internet of Things device. The basic constituent modules and main functions of the backscatter communication transmitter include:

[0052] - Antenna unit: used to receive radio frequency signals and control commands, and at the same time used to transmit the modulated backscatter signal.

[0053] - Energy harvesting module or power supply module: This module is used for radio frequency energy harvesting of backscatter communication devices, or other energy harvesting, including but not limited to solar energy, kinetic energy, mechanical energy, thermal energy, etc. In addition to the energy harvesting module, it may also include a battery power supply module. In this case, the backscatter communication device is a semi-passive device. The energy harvesting module or power supply module powers all other modules in the device.

[0054] - Microcontroller: It includes controlling baseband signal processing, energy storage or data scheduling status, switch switching, system synchronization, etc.

[0055] - Signal receiving module: It is used to demodulate control commands or data sent by the receiving end of backscatter communication or other network nodes.

[0056] - Channel coding and modulation module: Under the control of the controller, it performs channel coding and signal modulation, and realizes modulation by selecting different load impedances through a selection switch under the control of the controller.

[0057] - Memory or sensing module: It is used to store the identification ID information, location information or sensing data of the device.

[0058] In addition to the above typical constituent modules, the future backscatter communication transmitter can also integrate a tunnel diode amplifier module, a low-noise amplifier module, etc., to improve the receiving sensitivity and transmission power of the transmitter.

[0059] Optionally, the basic constituent modules and main functions of the backscatter communication receiver include:

[0060] - Antenna unit: It is used to receive the modulated backscatter signal.

[0061] - Backscatter signal detection module: It is 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.

[0062] - Demodulation and decoding module: It demodulates and decodes the detected signal to recover the original information stream.

[0063] In one implementation, according to the tag capabilities and the sources of capabilities, tags can be divided into:

[0064] - C1 / C2 Tags: Passive Tags, which obtain energy from the electromagnetic waves sent by the received RFID reader / writer and can only send out data after being activated;

[0065] - C3 Tags: Semi-passive Tags. The energy sources such as the tag's own battery only supply power to the circuits in the RFID tag and do not actively send out data signals. It only sends out data signals after being activated by the electromagnetic waves sent by the RFID reader / writer;

[0066] - C4 Tags: Active Tags, which actively send out data relying on energy sources such as their own installed batteries.

[0067] In another implementation, tags can be divided into:

[0068] - Device A: The tag is a passive tag without a storage capacitor / battery, relying on Radio Frequency (RF) signals for power supply. The received RF signal is the power supply signal for the rectifier and does not have the ability to generate carriers, with the lowest power consumption;

[0069] - Device B: The tag is a semi-passive tag with a storage capacitor / battery, relying on non-RF signals for power supply. Optionally, it has a PA / LNA or other active devices and does not have the ability to generate carriers, with the second lowest power consumption;

[0070] - Device C: The tag is an active tag with a storage capacitor / battery, relying on non-RF signals for power supply and having the ability to generate carriers, with the highest power consumption.

[0071] The above tags usually only have one working mode, that is, one of the passive, semi-passive or active working modes, which limits the flexibility of tag use. For example, in the sensing service scenario, when inventorying tags, a low-power and low-complexity passive working mode can be adopted; however, if the tag still reports sensing data in the passive working mode, when the data volume is large, problems such as communication failure due to insufficient power supply may occur. Therefore, in order to improve transmission reliability and coverage, integrating two communication modes in a tag, such as integrating a passive communication mode and an active communication mode, or integrating an active communication mode and a passive communication mode, is another important type of low-power tags that can be selected.

[0072] 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.

[0073] Next, in conjunction with the accompanying drawings, the information processing method, apparatus, communication device, and readable storage medium provided by the embodiments of this application will be described in detail through some embodiments and their application scenarios.

[0074] Please refer to Figure 2 , Figure 2 which is a flowchart of an information processing method provided by an embodiment of this application. This method is executed by a first device. As Figure 2 shown, this method includes the following steps:

[0075] Step 21: The first device obtains first information;

[0076] Step 22: The first device determines or executes a first action according to the first information.

[0077] In the embodiments of this application, the first device can be optionally a hybrid tag, etc. By switching between active and passive communication modes, the trade-off between communication coverage and power consumption can be effectively achieved. For example, when supporting short-range communication, the communication power consumption can be reduced by working in the passive communication mode; or when supporting long-range communication, the communication coverage can be ensured by working in the active communication mode.

[0078] Optionally, the first action includes at least one of the following:

[0079] The first device only works in the active communication mode; for example, the first device generates a carrier by itself for communication;

[0080] The first device only works in the passive communication mode; for example, the first device only works in the backscatter communication mode, that is, the first device does not generate a carrier, but performs backscatter communication based on the radio frequency carrier signal sent by other devices;

[0081] The first device works in both the active communication mode and the passive communication mode at the same time; for example, the first device supports both generating a carrier by itself for communication and not generating a carrier, but performing backscatter communication based on the radio frequency carrier signal sent by other devices;

[0082] The first device is in a sleep state or a non-transmitting state.

[0083] Thus, the configuration or scheduling of the first device integrating the active communication mode and the passive communication mode can be realized, so as to realize the communication mode switching and transmission parameter adjustment in different scenarios, and meet different communication performances (such as communication rate, communication distance, etc.) and power consumption requirements. Further, when the solution in this application is applied to hybrid tags, unified management and scheduling of the hybrid tags can be realized.

[0091] Whether the first device is allowed to report the request information or auxiliary information for work mode switching; for example, relevant switches can be configured to configure whether the first device is allowed to report the request information or auxiliary information for work mode switching, and optionally include the request information or auxiliary information of the transmission parameter related to the communication mode;

[0096] A working mode in which the active communication mode and the passive communication mode run in parallel; for example, the first device supports both generating a carrier wave independently for communication and not generating a carrier wave, but performing backscatter communication based on the radio frequency carrier wave signal sent by other devices;

[0097] The sleep state mode or the non-transmission state mode.

[0098] 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:

[0104] Optionally, the second transmission parameters of the first device are decoupled from the communication mode, that is, the first device cannot resolve the communication mode required for operation from these configured or indicated parameters. The second transmission parameters can include, but are not limited to, at least one of the following:

[0112] Optionally, in addition to being configured or indicated, the above communication mode switching condition can also be predefined or agreed upon by a protocol, etc., and no limitation is imposed thereon.

[0113] In the embodiment of the present application, the above execution of the first behavior may include:

[0114] The first device switches from being in the first communication mode to the second communication mode; wherein, the first communication mode and the second communication mode satisfy at least one of the following:

[0115] (1) The first communication mode is the active communication mode, and the second communication mode is any one of the following: the passive communication mode, the working mode in which the active communication mode and the passive communication mode run in parallel, the sleep state mode, or the non-transmission state mode;

[0116] (2) The first communication mode is the passive communication mode, and the second communication mode is any one of the following: the active communication mode, the working mode in which the active communication mode and the passive communication mode run in parallel, the sleep state mode, or the non-transmission state mode;

[0117] (3) The first communication mode is the working mode in which the active communication mode and the passive communication mode run in parallel, and the second communication mode is any one of the following: the active communication mode, the passive communication mode, the sleep state mode, or the non-transmission state mode;

[0118] (4) The first communication mode is the sleep state mode or the non-transmission state mode, and the second communication mode is any one of the following: the active communication mode, the passive communication mode, the working mode in which the active communication mode and the passive communication mode run in parallel;

[0119] (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.

[0120] For example, the above execution of the first line may include at least one of the following:

[0121] (a) The first device switches from a dormant, shutdown state or a non-transmission state to an active communication mode. For example, when the first device just enters the network or wakes up from a long-term dormant state, the network or system configuration defaults to enter the active communication mode to ensure communication performance.

[0122] (b) The first device switches from a dormant, shutdown state or a non-transmission state to a passive communication mode. For example, when the first device just enters the network or wakes up from a long-term dormant state, the network or system configuration defaults to enter the passive communication mode to ensure the lowest device power consumption.

[0123] (c) The first device switches from a dormant, shutdown state or a non-transmission state to a state where both the active and passive communication modes work simultaneously. For example, when the first device just enters the network or wakes up from a long-term dormant state, the network or system configuration defaults to enter the active and passive simultaneous working communication mode to ensure the best communication performance of the device.

[0124] (d) The first device switches from an active communication mode to a passive communication mode. For example, if the power 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 content is lower than a preset threshold, then it switches from the active communication mode to the passive communication mode to reduce the device power consumption.

[0125] (e) The first device switches from an active communication mode to a state where both the active and passive communication modes work simultaneously. For example, if the number of transmission failures of the first device in the active communication mode exceeds a preset threshold, or the signal quality is lower than a preset threshold, or the size of the transmitted message content is lower than a preset threshold, then it switches to the state where both the active and passive communication modes work simultaneously to further improve the communication performance.

[0126] (f) The first device switches from a passive communication mode to an active communication mode. For example, if the number of transmission failures of the first device in the passive communication mode exceeds a preset threshold, or the signal quality is lower than a preset threshold, or the size of the transmitted message content is higher than a preset threshold, then it switches to the active communication mode to further improve the communication performance.

[0127] (g) The first device switches from the passive communication mode to the state where both the active and passive communication modes work simultaneously. For example, if the number of transmission failures of the first device in the passive communication mode exceeds a preset threshold, or the signal quality is lower than the preset threshold, or the size of the transmitted message content is higher than the preset threshold, then it switches to the state where both the active and passive communication modes work simultaneously to further improve communication performance.

[0128] (h) The first device switches from the working mode where the active and passive communication modes are parallel to the passive communication mode. For example, if the size of the transmitted information content of the first device in the working mode where the active and passive communication modes are parallel is lower than a certain threshold, or the power is lower than a certain threshold, or the number of transmission failures in the active communication mode exceeds the preset threshold, or the signal quality in the active communication mode is lower than a certain threshold, then it switches to the passive communication mode.

[0129] (i) The first device switches from the working mode where the active and passive communication modes are parallel to the active communication mode. For example, if the size of the transmitted information content of the first device in the working mode where the active and passive communication modes are parallel is lower than a certain threshold, or the power is lower than a certain threshold, or the number of transmission failures in the passive communication mode exceeds the preset threshold, or the signal quality in the passive communication mode is lower than a certain threshold, then it switches to the active communication mode.

[0130] (j) The first device switches from the passive communication mode, or the active communication mode, or the state where both the active and passive communication modes work simultaneously to the sleep state.

[0131] (k) The first device switches from the passive communication mode, or the active communication mode, or the state where both the active and passive communication modes work simultaneously to different transmission parameters in the same mode.

[0184] For example, the bearing manner of the first information can include at least one of the following:

[0185] (a) Carried by RRC signaling or NAS signaling; this method requires the first device to have an RRC protocol layer or an NSA protocol layer, and is applicable when the first device accesses the network and selects the default communication mode or transmission parameters according to the previous RRC configuration or NAS configuration information for network access.

[0186] (b) Carried by MAC CE; for example, similar to the Discontinuous Reception (DRX) mechanism, using MAC CE signaling to configure the communication state or transmission parameters of the first device, this situation is also applicable to the first device with weak capabilities that does not support RRC signaling or NAS signaling.

[0187] (c) Carried by dynamic DCI signaling, SCI signaling or other L1 signaling; this method is applicable during data transmission, where the second device dynamically indicates the communication mode or transmission parameters of the first device through DCI, SCI or L1 signaling.

[0189] It should be noted that the above various signaling can exist simultaneously, and the final communication mode or transmission parameters are determined according to the priority. For example, the first device supports both RRC configuration and dynamic indication based on DCI, SCI or physical layer (L1) signaling. After entering the network, it has been communicating using the communication mode and transmission parameters of the RRC configuration until it receives DCI, SCI or physical layer (L1) signaling to change the communication mode or transmission parameters, and then switches to the corresponding communication mode or transmission parameters.

[0192] Optionally, the first signal may be a signal carrying valid data such as the identification ID, sensor data, positioning information or signal measurement value to be sent by the first device.

[0193] Optionally, the first signal may be selected as a synchronization signal, a pilot signal or a reference signal, etc.

[0194] Optionally, the third device may be a device different from the second device, that is, at this time, the second device that performs configuration or indication is different from the third device that receives the signal of the first device.

[0195] Optionally, the third device may also be the same device as the second device, that is, at this time, the second device that performs configuration or indication is the same device as the third device that receives the signal of the first device.

[0256] The present application will be described below with reference to specific embodiments.

[0257] Embodiment 1

[0258] In this first embodiment, the first device (such as a hybrid tag device) determines the communication mode and corresponding transmission parameters through network configuration information or system configuration information.

[0259] In a possible scenario, for a first device that has previously accessed the network, the first device retains some network configuration information and uses the communication mode and transmission parameters corresponding to this configuration information for communication when accessing the network next time. For example, for a first device that supports the RRC protocol or the NAS protocol, before entering the sleep state or shutting down, the first device still retains the network configuration information regarding the default communication mode and transmission parameters during this network access or the first network access; after the first device wakes up or powers on and accesses the network next time, it can communicate using the default communication mode and transmission parameters of the network configuration.

[0260] In another possible scenario, when the first device leaves the factory, the merchant uses the factory default settings to solidify the default communication mode and transmission parameters of the first device. These factory default configuration parameters are stored in the storage area of the first device in a fixed manner and do not require network configuration. This method is applicable to tag devices with weak network access capabilities that do not support network system configuration information.

[0261] The above two methods are applicable to the communication transmission configuration of the first device in a fixed scenario or when the first device has just accessed the network.

[0262] Embodiment 2

[0263] In the above Embodiment 1, determining the communication mode and the corresponding transmission parameters through network configuration information or system configuration information can only solve the communication configuration in a fixed scenario or when the first device has just accessed the network. However, in more scenarios, such as when the first device moves, the surrounding channel environment changes, the transmission service of the first device changes, the state of the first device changes, etc., the network needs to dynamically schedule or indicate the communication mode and transmission parameters of the first device.

[0264] In a possible scenario, the first device switches from the active communication mode state to the passive communication mode state. For example, when the power of the first device 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, or the number of consecutive successful transmissions exceeds the preset threshold, it switches from the active communication mode to the passive communication mode to reduce the device power consumption.

[0265] In a possible scenario, the first device switches from the active communication mode state to the state where both the active and passive communication modes work simultaneously. For example, when the number of transmission failures of the first device 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, it switches to the state where both the active and passive communication modes work simultaneously to further improve the communication performance.

[0266] In a possible scenario, the first device switches from the passive communication mode state to the active communication mode state. For example, if the number of transmission failures of the first device in the passive communication mode exceeds a preset threshold, or the signal quality is lower than the preset threshold, or the size of the transmitted message content is higher than the preset threshold, it switches to the active communication mode to further improve communication performance.

[0267] In a possible scenario, the first device switches from the passive communication mode state to the state where both the active and passive communication modes work simultaneously. For example, if the number of transmission failures of the first device in the passive communication mode exceeds a preset threshold, or the signal quality is lower than the preset threshold, or the size of the transmitted message content is higher than the preset threshold, it switches to the state where both the active and passive communication modes work simultaneously to further improve communication performance.

[0268] In a possible scenario, the first device switches from the state where both the active and passive communication modes work simultaneously to the passive communication mode state. For example, if the size of the transmitted information content of the first device in the state where both the active and passive communication modes work simultaneously 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, it switches to the passive communication mode.

[0269] In a possible scenario, the first device switches from the state where both the active and passive communication modes work simultaneously to the active communication mode state. For example, if the size of the transmitted information content of the first device in the state where both the active and passive communication modes work simultaneously 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 the preset threshold, or the signal quality in the passive communication mode is lower than a certain threshold, it switches to the active communication mode.

[0270] 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 state 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.

[0271] Embodiment III

[0272] In addition to the second device determining the communication mode and transmission parameters of the first device based on the information it obtains itself, since the first device knows best 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 with; then, the second device combines the auxiliary information / request information of the first device and other parameters to configure or schedule the communication mode and transmission parameters of the first device.

[0273] In a possible solution, the first device sends its own status information or auxiliary information to the second device, including at least one of the following: the power information of the first device, the energy storage status information of the first device, the overheat information of the first device, the signal / channel measurement information of the first device in the active communication mode, the signal / channel measurement information of the first device in the passive communication mode, the 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 this auxiliary information sent by the first device, and combines the resource allocation situation, interference situation, and statistically obtained signal quality situation of the entire network system at present, and finally configures or instructs the first device.

[0274] In another possible solution, the first device first determines appropriate communication mode and transmission parameters based on parameters such as its own status and the QoS requirements of the service to be sent, and sends a request information for the communication mode and transmission parameters that it prefers to work in or hopes to be configured with to the second device; then, the second device determines the communication mode and transmission parameters of the first device based on this request information sent by the first device, and combines the resource allocation situation, interference situation, and statistically obtained signal quality situation of the entire network system at present, and finally configures or instructs the first device.

[0275] For example, if the first device requests to switch from the active communication mode to the passive communication mode according to its own energy-saving or energy storage situation, the possible process includes:

[0276] S1: The second device first configures the communication mode switch, that is, whether to allow the first device to report the working mode or the request for transmission parameters related to the communication mode;

[0277] S2: If reporting is allowed, the first device reports the request for the passive communication mode; optionally, the request information can also include the transmission parameters in the passive communication mode;

[0278] S3: Optionally, the second device configures or instructs the passive communication mode of the first device through the above first information, or configures or instructs the passive communication mode and the corresponding transmission parameters.

[0279] For another example, if 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 statistics in the passive communication mode, the possible process may include:

[0280] S1: The second device first configures the communication mode switch, that is, whether to allow the first device to report the working mode or a transmission parameter request related to the communication mode;

[0281] S2: If reporting is allowed, the first device reports a request for the active communication mode; optionally, the request information may further include transmission parameters in the passive communication mode;

[0282] S3: Optionally, the second device configures or indicates the active communication mode of the first device through the above-mentioned first information, or configures or indicates the active communication mode and the corresponding transmission parameters.

[0283] Embodiment 4

[0284] In this Embodiment 4, it is mainly described that the first device and the third device first preset rules or switching conditions. As long as the first device and the third device 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 the need for the second device to configure / schedule / indicate the communication mode and transmission parameters of the first device. Among them, the preset rules or switching conditions of the first device and the third device may also be network-configured or factory-set, and this case does not make restrictions.

[0285] 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 for illustrative purposes):

[0286] (1) When the consecutive ACK count in the passive communication mode is greater than a preset count, such as 8, the first device continues to operate in the passive communication mode; when the NACK count in the passive communication mode is greater than a preset count, such as 3, it switches to the active communication mode;

[0287] (2) When the consecutive ACK count in the active communication mode is greater than a preset count, such as 8, it switches to the passive communication mode; when the consecutive NACK count in the active communication mode is greater than a preset count, such as 3, the first device switches to the state of operating in both the active communication mode and the passive communication mode simultaneously;

[0288] (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; 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.

[0289] 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.), and the corresponding rules are similar to the NACK / ACK solution, which will not be repeated here.

[0290] In another feasible solution, the first device and the third device can adaptively change the communication mode and transmission parameters according to 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, it will actively change to active communication mode.

[0291] In another feasible solution, during the communication between the first device and the third device, if there is still no network scheduling after exceeding the preset time window, the behavior of the first device can be defined as follows (this is only an example):

[0292] (1) If the preset time window T is exceeded 1 , the first device enters a passive communication mode, thereby saving device power consumption;

[0293] (2) If the preset time window T is exceeded 2 , the first device enters a dormant state, thereby further saving the power consumption of the terminal.

[0294] It is worth noting that the above communication mode can also correspond to a set of transmission parameters, thereby further saving network signaling overhead. This method is suitable for tag devices with strong capabilities and certain measurements or autonomous decision-making. The advantage is that the communication mode can be switched adaptively according to preset rules without network scheduling.
