[0004] Passive radio frequency identification (RFID) sensor tags with integrated ultra-low-power sensors can simultaneously perform object identification and parameter sensing functions through radio frequency energy recovery.

[0235] As shown in FIG1 , at least one embodiment of the present disclosure provides an information transmission method, applied to a first node, comprising:

[0236] Step 101: Send first information to a second node, where the first information is used to indicate at least one of the power capability, power status, and event information of the first node.

[0237] It should be noted that after receiving the first information, the second node can determine whether to transmit data and / or signaling, and / or whether to schedule data and / or signaling based on the first information, so that the second node can perform data communication based on the status of the first node, avoiding the second node that does not have the ability to support both data communication and energy collection from performing data communication when the first node is collecting energy, thereby achieving the purpose of combining mobile communication scenarios with RF energy collection.

[0238] Optionally, the first information includes at least one of the following: power capacity of the first node, power status of the first node, and event information.

[0239] Here, transmission refers to sending and / or receiving.

[0240] Optionally, the second node may also determine, based on the type and / or power capacity of the first node, whether the first node has the capability of simultaneously supporting data communication and energy harvesting.

[0241] Optionally, if the second node determines to transmit data and / or signaling based on the first information, the transmission power, rate, waveform, etc. to be used may be further selected based on the first information. It should be noted that adjusting the transmission power, rate, and waveform of the excitation wave or excitation signal by the second node will also affect the reflection coefficient used by the first node, that is, the reflection coefficient used by the first node will also change with changes in the transmission power, rate, and waveform used by the second node.

[0242] Optionally, only the backscatter waveform is required for the first node that does not support active transmission.

[0243] Optionally, the content in the first information in the present disclosure may be sent in one message or in multiple messages.

[0244] Optionally, in one implementation, the power status includes at least one of the following: the power level of the first node, indication information that the first node needs to be charged, the time point when the first node needs to be charged, the available power after the first node is charged, the power consumption status of the first node, the duration for which the first node needs to be charged, and receiving sensitivity information.

[0245] The power level of the first node is indicated by at least one of a power level value, a power level label, a power level grade, and an energy collection state.

[0246] Optionally, the energy harvesting state includes at least one of the following states:

[0247] Collect energy status;

[0248] The device is fully charged;

[0249] Start charging state.

[0250] The details are as follows:

[0251] Collecting energy; indicating that the first node is collecting energy or charging until the capacitor voltage reaches a first predetermined threshold, such as 1V;

[0252] The device is fully charged; it indicates that the first node starts to operate or is operating; that is, the capacitor voltage reaches a first predetermined threshold, such as 1V; charging is started; it indicates that the first node operates within the on-time until the voltage reaches a second predetermined threshold, such as 0.7V, for example, about half of the energy storage (ES), and is ready to start charging. At this time, the first node stops operating or maintains operating.

[0253] Here, operation can also mean communication.

[0254] For example, different amounts of electricity possessed by the first node are identified by different electricity levels, and specific electricity levels can be identified by different indexes, for example, index 1 corresponds to 12.5, index 2 corresponds to 25, ..., and index m corresponds to 2500.

[0255] Optionally, the power consumption status of the above-mentioned first node is used to indicate the power consumed by the first node when transmitting data and / or signaling; it should be noted that transmitting data may include: sending data and / or receiving data; transmitting signaling may include: sending signaling and / or receiving signaling.

[0256] Optionally, the consumed power is related to at least one of the following conditions:

[0257] A11, transmission rate;

[0258] This situation can be understood as different data and / or signaling transmission rates corresponding to different power consumption, and the first node needs to determine the power consumption based on the data and / or signaling transmission rate; or different data and / or signaling transmission rates corresponding to different power consumption, and the first node needs to determine whether the remaining power can meet the data and / or signaling transmission rate.

[0259] A12, transmission distance;

[0260] This situation can be understood as different data and / or signaling transmission distances corresponding to different power consumption, and the first node needs to determine the power consumption based on the data and / or signaling transmission distance; or different data and / or signaling transmission distances corresponding to different power consumption, and the first node needs to determine whether the remaining power can meet the data and / or signaling transmission distance.

[0261] A13, the size of the data packet;

[0262] This situation can be understood as different data packet sizes corresponding to different power consumption, and the first node needs to determine the power consumption based on the size of the data packet; or different data packet sizes corresponding to different power consumption, the first node needs to determine whether the remaining power can meet the transmission of the data packets corresponding to the data and / or signaling.

[0263] A14. Transmission conditions;

[0264] This situation can be understood as different data and / or signaling transmission conditions corresponding to different power consumption, and the first node needs to determine the power consumption based on the data and / or signaling transmission conditions; or different data and / or signaling transmission conditions corresponding to different power consumption, the first node needs to determine whether the remaining power can meet the data and / or signaling transmission conditions.

[0265] Optionally, the transmission condition may include but is not limited to at least one of the following: whether it is a direct path, whether the signal quality is higher than a certain threshold, and the transmission scenario (eg, indoors or outdoors).

[0266] A15, the moving speed of the first node;

[0267] This situation can be understood as different moving speeds corresponding to different power consumption, and the first node needs to determine the power consumption based on the moving speed; or different moving speeds corresponding to different power consumption, and the first node needs to determine whether the remaining power can meet the transmission of data and / or signaling at the moving speed of the first node.

[0268] A16. Transmission delay requirements;

[0269] This situation can be understood as different transmission delay requirements corresponding to different power consumption, and the first node needs to determine the power consumption based on the transmission delay requirements; or different transmission delay requirements correspond to different power consumption, and the first node needs to determine whether the remaining power can meet the transmission delay requirements of data and / or signaling.

[0270] Optionally, the receiver sensitivity defines the minimum signal strength a receiver can receive and still function properly. Improving signal reception sensitivity can enhance the wireless product's ability to capture weak signals. This situation can be understood as different receiver sensitivity requirements corresponding to different power consumptions, and the first node needs to determine the power consumption based on the receiver sensitivity requirements; or the first node and / or the second node have different receiver sensitivities corresponding to different power consumptions, and the first node needs to determine whether the remaining power can meet the receiver sensitivity requirements for data and / or signaling between the first node and the second node, or between the first node and another device.

[0271] Therefore, reporting the power consumption status to the second node helps the second node accurately determine the time and / or duration when the first node needs to be charged, as well as the data characteristics that can be sent before charging, including transmission rate, transmission distance and transmission packet size.

[0272] Optionally, in one implementation, the power capability includes at least one of the following:

[0273] Sustainable operation time (for example, the time unit can be seconds, milliseconds, etc.), harvesting efficiency, charging time, reflection efficiency, power gain, power duration of the energy storage device, and storage capacity of the energy storage device.

[0274] It's important to note that energy harvesting is a technology that converts natural energy, such as light, heat, sound, and motion, into electrical energy. Harvesting efficiency, or energy conversion efficiency, refers to the ratio of the usable energy output of an energy conversion device to its input energy. The usable output energy can be electrical energy, mechanical work, or heat. While there's no consistent definition of energy conversion efficiency, it primarily relates to the degree to which the output energy is usable. Generally speaking, energy conversion efficiency is a dimensionless number between 0 and 1.

[0286] It should be noted here that the transmission mentioned in the embodiments of the present disclosure includes: sending and / or receiving.

[0287] The event reporting method allows the second node to timely and effectively understand the power level of the first node in different scenarios, avoiding invalid or inefficient scheduling, and reducing the signaling frequency of the first node, further saving energy consumption.

[0316] Optionally, in one implementation, the method further includes at least one of the following:

[0320] That is to say, in this case, the first node determines its own power status based on the downlink measurement results.

[0325] Optionally, the characteristic of the energy harvesting method refers to at least one of the following methods:

[0326] RF energy harvesting;

[0327] Energy harvesting from at least one of wireless waves, signals, data, sunlight, and light.

[0328] It should be noted that the above method can be understood as the first node can decide on its own which method to use to determine the power status and available power.

[0329] Optionally, in one implementation, the method further includes:

[0330] Receive a power determination criterion sent by the second node, where the power determination criterion includes at least one of the following:

[0336] D11. Determine a period and / or frequency for reporting the first information according to the power level and / or reception level;

[0337] Optionally, in an embodiment of the present disclosure, the period and / or frequency corresponding to the power level and / or reception level can be pre-set (protocol agreement and / or network side configuration). For example, a correspondence table between the power level and / or reception level and the period and / or frequency is set. The first node only needs to search the correspondence table based on the current power level and / or reception level to determine the period and / or frequency of the first information, and then send the first information based on the period or frequency.

[0338] D12. If the power level meets the requirement of the cth threshold, determine to report the first information according to the first period, where the requirement of meeting the cth threshold includes: the power level is higher than and / or equal to the cth threshold, and / or the power level is lower than and / or equal to the cth threshold;

[0339] The cth threshold defines at least one of a specific power level value, a power level label, and a power level grade.

[0340] D13. If the power level meets the requirement of the dth threshold, determine to report the first information according to the second period, where the requirement of the dth threshold includes: the power level is higher than and / or equal to the dth threshold, and / or the power level is lower than and / or equal to the dth threshold;

[0341] The cth threshold defines at least one of a specific power level value, a power level label, and a power level grade.

[0342] The above-mentioned c and d are integers greater than or equal to 0 and can be the same or different.

[0343] The values ​​of the first cycle and the second cycle are integers or infinity; if they are infinity, the first node reports only once.

[0344] For example, if the power level is less than or equal to the cth threshold or the power level is less than or equal to the dth threshold, it can be understood that the power of the first node is low, or it can be considered that the first node is in a low-power state; if the power level is greater than the cth threshold or the power level is greater than the dth threshold, it can be understood that the power of the first node is not low, or it can be considered that the first node is not in a low-power state.

[0345] Optionally, the period length of the second period is smaller than the period length of the first period.

[0346] That is to say, when the first node is in a low-power state, in order to reduce power consumption, it is necessary to reduce the reporting frequency of the first information or increase the reporting period of the first information; when the first node is not in a low-power state, the first node can adopt a normal reporting frequency or a normal reporting period of the first information, so that the second node can understand the status of the first node in a timely manner.

[0347] For example, the normal reporting period of the first node is set to 100 milliseconds. When the first node is in a low-power state, the reporting period adopted by the first node is 500 milliseconds. When the first node is not in a low-power state, the reporting period adopted by the first node is 100 milliseconds.

[0348] D14. If the reception level meets the requirement of the e-th threshold, determine to report the first information according to the third period, where the requirement of meeting the e-th threshold includes: the reception level is higher than and / or equal to the e-th threshold, and / or the reception level is lower than and / or equal to the e-th threshold;

[0351] The fth threshold defines at least one of a specific receiving level value, a receiving level label, and a receiving level grade;

[0352] For example, if the receiving level is less than or equal to the e-th threshold or the receiving level is less than or equal to the f-th threshold, it can be understood that the battery of the first node is low, or it can be considered that the first node is in a low-level state or a low-battery state; if the receiving level is greater than the e-th threshold or the receiving level is greater than the f-th threshold, it can be understood that the battery of the first node is not low, or it can be considered that the first node is not in a low-level state or a low-battery state.

[0353] Optionally, the period length of the fourth period is shorter than the period length of the third period.

[0354] The above-mentioned e and f are integers greater than or equal to 0 and may be the same or different.

[0355] That is to say, when the first node is in a low-level state, in order to reduce power consumption, it is necessary to reduce the reporting frequency of the first information or increase the reporting period of the first information; when the first node is not in a low-level state, the first node can adopt a normal reporting frequency or a normal reporting period of the first information, so that the second node can understand the status of the first node in a timely manner.

[0356] For example, the normal reporting period of the first node is set to 100 milliseconds. When the first node is in a low-level state, the reporting period adopted by the first node is 500 milliseconds. When the first node is not in a low-level state, the reporting period adopted by the first node is 100 milliseconds.

[0362] For example, the aforementioned type A, type B, and type C IoT terminals may be Ambient Internet of Things (A-IoT) terminals.

[0363] E15: Whether the IoT terminal carries capacitors;

[0364] It should be noted that whether or not a capacitor is carried in this case can also be understood as whether the IoT terminal has energy storage capability.
