Description

Communication method and related device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 30, 2024, with application number 202410133374.4 and application name “Communication Methods and Related Devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to communication methods and related devices. Background Art

[0003] With the development of wireless networks and the evolution of business needs, a vast number of Internet of Things (IoT) nodes are now present in these networks. IoT nodes are typically small and cannot carry large-capacity batteries, resulting in short standby life. Wireless energy transfer (WPT) through base stations is one important approach to addressing the short battery life of IoT nodes.

[0004] In the technical solution of implementing WPT through base stations to solve the short battery life of IoT nodes, the base station sends a wireless signal. After the IoT node receives the wireless signal sent by the base station, it can obtain the energy in the wireless signal to charge the battery.

[0005] However, the energy consumption of base stations is relatively high, so how to reduce the energy consumption of base stations is a problem that needs to be solved. Summary of the Invention

[0006] The present application provides a communication method, a communication device, and a communication system, which help save energy consumed by network equipment to charge terminals.

[0007] In a first aspect, the present application provides a communication method, which includes: sending first information to a network device, where the first information indicates a first intensity, and the first intensity is the intensity of at least one energy in the environment where the terminal is located; and receiving a charging signal sent by the network device based on the first information.

[0008] The method may be executed by a terminal or a communication device applied in the terminal, or it can be said that the method may be applied to the terminal.

[0009] In this method, an indication of the intensity of one or more energies in the environment where the terminal is located is sent to the network device, which helps the network device to know the intensity of energy that the terminal can obtain from the environment, thereby helping the network device to determine a charging signal with appropriate power based on the intensity of the environmental energy, and further helping to reduce the energy consumption of the network device in charging the terminal.

[0010] In some possible implementations of the method, the at least one energy may include at least one of the following energies: wireless radio frequency energy, light energy, thermal energy, or vibration energy.

[0011] Regarding the first information indicating the intensity of the at least one energy, in some possible implementations, the first information may include at least one piece of energy information, each piece of energy information corresponding one-to-one to the at least one energy, and each piece of energy information in the at least one piece of energy information indicating the intensity of the corresponding energy. In other words, the intensity of each type of energy is indicated separately.

[0012] Each type of energy is indicated separately, so that network devices can clearly know the intensity of each type of energy, thereby knowing the intensity distribution of each type of energy, predicting the energy arrival time in advance, and optimizing resource scheduling.

[0013] Regarding the first information indicating the intensity of the at least one energy, in some other possible implementations, the first information indicates the total intensity of all types of energy in the at least one energy. Indicating the total intensity can reduce the amount of reported information, shorten transmission time, and save power.

[0014] In some possible implementations of the method, the first information further indicates a duration of the at least one energy. This implementation helps the network device accurately determine the charging power that the at least one energy can provide to the terminal based on the duration of the at least one energy, thereby helping the network device accurately determine a charging signal with appropriate power, thereby helping to reduce energy consumption of the network device charging the terminal.

[0015] Regarding the first information indicating the duration of the at least one energy, in some possible implementations, the first information may include at least one duration information, each of which corresponds one-to-one to the at least one energy, and each of which indicates the duration of the corresponding energy. In other words, the duration of each energy is indicated separately.

[0016] The duration of each energy is indicated separately, so that network devices can clearly know the duration of the intensity of each energy, thereby knowing the intensity distribution of each energy over time, predicting the energy arrival time in advance, and optimizing resource scheduling.

[0017] Regarding the first information indicating the duration of the at least one type of energy, in some other possible implementations, the first information indicates a duration for all types of energy in the at least one type of energy.

[0018] For example, the duration indicated by the first information may be the duration of the energy with the highest intensity among the at least one energy, may be the shortest duration among the durations corresponding to the at least one energy, may be the average duration of the durations corresponding to the at least one energy, or may be the total duration of the energy type with the highest intensity among the at least one energy.

[0019] In some possible implementations of this method, the first information further indicates the type of each energy in the at least one energy source. This facilitates network devices to optimize the scheduling of charging resources. For example, since vibration energy dissipates easily, more charging resources can be pre-allocated. This also facilitates the temporal distribution of network devices or each energy type, allowing for early prediction of energy arrival times and optimized resource scheduling.

[0020] In some possible implementations of the method, the first information indicates both a duration of the at least one energy and a type of each energy in the at least one energy.

[0021] If the at least one type of energy includes radio frequency energy, in some possible implementations of the method, the first information also indicates the frequency band of the radio frequency energy. This helps the network device understand the temporal distribution of energy at each different frequency point, predict the energy arrival time in advance, and optimize resource scheduling.

[0022] In the case where the first information also indicates the frequency band of the radio frequency energy, in some possible implementations, the first information may indicate the total intensity of the radio frequency energy of all frequency bands, or the first information may indicate the intensity of the radio frequency energy of each frequency band separately.

[0023] The separate indication of the RF energy intensity in each frequency band allows network devices to clearly understand the intensity of each type of energy, thereby understanding the intensity distribution of RF energy in each frequency band, predicting the energy arrival time in advance, and optimizing resource scheduling.

[0024] Indicating the total intensity of radio frequency energy in multiple frequency bands can reduce the amount of reported information, shorten transmission time, and save power.

[0025] In some possible implementations of the method, before sending the first information to the network device, the method further includes: receiving second information from the network device, where the second information is used to determine resources for collecting environmental energy by the terminal.

[0026] Optionally, at the resource indicated by the second information where the terminal collects ambient energy, the network device does not send a signal. In this way, the ambient energy collected by the terminal at this resource does not include the radio frequency energy sent by the network device. This prevents the radio frequency energy reported by the terminal from including the radio frequency energy provided by the network device, thereby helping the network device accurately understand the energy that the environment can provide to the terminal, and further helping the network device accurately determine the energy it needs to provide to the terminal.

[0027] For example, the resource includes a time domain resource, and the network device does not send a signal on all or part of the frequency domain resources at the time domain resource.

[0028] For another example, the resource includes a time domain resource and a frequency domain resource, and the network device does not send a signal at the time-frequency resource and the frequency domain resource.

[0029] Regarding the resources used by a terminal to collect ambient energy, in some possible implementations, these resources may include multiple time-domain resources, with different time-domain resources corresponding to different frequency-domain resources. In this implementation, because different time-domain resources correspond to different frequency-domain resources, the network device will not transmit signals for different periods of time on different frequency-domain resources. Alternatively, the network device will be able to transmit signals on at least some of the frequency-domain resources within each of these time-domain resources. Therefore, the accurate ambient energy collection by the terminal will not affect the network device's communications.

[0030] In some possible implementations of the method, before receiving the second information from the network device, the method further includes: sending third information to the network device, where the third information is used to instruct the terminal to request the network device to perform radio frequency energy measurement.

[0031] That is, the terminal informs the network device that the terminal needs to perform radio frequency energy measurement, so that the network device can configure resources for the terminal to collect environmental energy.

[0032] Optionally, the third information may also be understood as being used to instruct the terminal to request the network device to perform environmental energy measurement, or the third information may also be understood as being used to request the terminal to collect resources for environmental energy.

[0033] Regarding the third information, in some possible implementations, the third information also indicates the operating frequency band of the terminal. This helps to avoid the network device configuring invalid resources for collecting ambient energy for the terminal and avoids waste of signaling overhead.

[0034] In some possible implementations of the method, the method further includes: sending fourth information to the network device, the fourth information indicating a second intensity, the second intensity being the intensity of at least one energy in the environment where the terminal is located, and the measurement period of the second intensity being after the measurement period of the first intensity.

[0035] That is, the terminal can update the energy intensity in its environment to the network device, which helps the network device determine a charging signal that can meet the terminal charging needs and save energy consumption of the network device based on the updated intensity.

[0036] In some possible implementations of the method, the fourth information indicates the second intensity, including: the fourth information indicates a difference between the second intensity and the first intensity.

[0037] In this implementation, the fourth information informs the network device of the second strength by indicating the difference between the second strength and the first strength. Compared with directly indicating the second strength, since the difference is smaller than the second strength, signaling overhead can be saved.

[0038] In some possible implementations of the method, sending the fourth information to the network device includes sending the fourth information to the network device when the absolute value of the difference between the second intensity and the first intensity is greater than or equal to a threshold. In other words, when the absolute value of the difference between the second intensity and the first intensity is less than the threshold, not sending the fourth information to the network device.

[0039] In some possible implementations of the method, the method further includes: receiving fifth information from a network device, where the fifth information is used to configure the threshold.

[0040] The threshold determines the frequency of feedback. A higher threshold reduces the frequency of feedback, which can save terminal energy, but also reduces the real-time nature of environmental energy updates. Configuring a threshold on network devices adjusts the frequency of environmental energy updates, ensuring a balanced and relatively efficient balance between the real-time nature of environmental energy updates and the energy consumption of terminal feedback. For example, the threshold can be raised when environmental energy fluctuations are small, and lowered when fluctuations are large.

[0041] In some possible implementations of the method, resources used to send the fourth information are preconfigured or predefined.

[0042] In some possible implementations of the method, the method further includes receiving sixth information from the network device, the sixth information indicating that charging has ended. This allows the terminal to stop reporting ambient energy information to the network device based on the sixth information, thereby avoiding wasted signaling overhead. Furthermore, the terminal can free up resources previously allocated for reporting ambient energy information for other purposes, thereby improving resource utilization.

[0043] In some possible implementations of the method, the method further includes: sending seventh information to the network device, the seventh information indicating that charging is complete. In this way, the network device can free up resources allocated for reporting environmental energy information for other purposes, thereby improving resource utilization.

[0044] In a second aspect, the present application provides a communication method, comprising: receiving first information from a terminal, the first information indicating a first intensity, the first intensity being the intensity of at least one energy in the environment where the terminal is located; and sending a charging signal to the terminal according to the first information.

[0045] The method can be executed by a network device or a communication device applied to a network device, or it can be said that the method can be applied to a network device.

[0046] In this method, the network device obtains the intensity of one or more energies in the environment where the terminal is located, which helps the network device to obtain the intensity of energy that the terminal can obtain from the environment, thereby helping the network device to determine a charging signal with appropriate power based on the intensity of the environmental energy, and further helping to reduce the energy consumption of the network device in charging the terminal.

[0047] In some possible implementations of the method, the at least one energy may include at least one of the following energies: wireless radio frequency energy, light energy, thermal energy, or vibration energy.

[0048] In some possible implementations of the method, the first information further indicates a duration and / or type of the at least one energy.

[0049] In some possible implementations of the method, the at least one type of energy includes radio frequency energy, wherein the first information further indicates a frequency band of the radio frequency energy.

[0050] In some possible implementations of the method, before receiving the first information from the terminal, the method further includes: sending second information to the terminal, where the second information is used to determine resources for the terminal to collect environmental energy.

[0051] In some possible implementations of the method, before sending the second information to the terminal, the method further includes: receiving third information from the terminal, where the third information is used to instruct the terminal to request the network device to perform radio frequency energy measurement.

[0052] In some possible implementations of the method, the third information further indicates an operating frequency band of the terminal.

[0053] In some possible implementations of the method, the resources used by the terminal to collect ambient energy include multiple time domain resources, and different time domain resources in the multiple time domain resources correspond to different frequency domain resources.

[0054] In some possible implementations of the method, the method further includes: receiving fourth information from the terminal, the fourth information indicating a second intensity, the second intensity being the intensity of at least one energy in the environment where the terminal is located, and the measurement period of the second intensity being after the measurement period of the first intensity.

[0055] In some possible implementations of the method, the fourth information indicates the second intensity, including: the fourth information indicates a difference between the second intensity and the first intensity.

[0056] In some possible implementations of the method, an absolute value of a difference between the second intensity and the first intensity is greater than or equal to a threshold.

[0057] In some possible implementations of the method, the method further includes: sending fifth information to the terminal, where the fifth information is used to configure the threshold.

[0058] In some possible implementations of the method, resources used to receive the fourth information are preconfigured or predefined.

[0115] In this method, the terminal sends an indication of the intensity of one or more energies in the environment where the terminal is located to the network device, so that the network device can know the intensity of energy that the terminal can obtain from the environment, and thus the network device can determine a charging signal with appropriate power based on the intensity of the environmental energy, thereby reducing the energy consumption of the network device in charging the terminal.

[0116] In the embodiment of the present application, the energy in the environment where the terminal is located can be understood as the energy that the terminal can obtain from the environment, which can be called ambient energy (ambient energy, ambient energy harvesting, or energy harvesting), and the first information can be called ambient energy information.

[0117] In the embodiment of the present application, the intensity of energy may also be referred to as the power intensity of energy.

[0118] In some implementations, the at least one energy may include at least one of the following energies: radio frequency energy, light energy, thermal energy, or vibration energy. The radio frequency energy may be referred to as radio frequency energy.

[0119] The at least one energy may include one type of energy or multiple types of energy.

[0120] In some implementations, the at least one energy may include several types of energy that are predefined or preconfigured.

[0121] For example, the at least one energy includes one type of energy, such as radio frequency energy, ambient light energy, vibration energy, or thermal energy. In this case, an example of the content included in the first information is as follows: "Intensity: -20dBm." This indicates that the terminal can collect energy intensity from the environment of -20dBm.

[0122] When the at least one energy includes multiple energies, in some implementations, the first information may indicate the intensity of each energy individually, or may indicate the total intensity of the multiple energies.

[0123] When the at least one energy source includes two energy sources, such as radio frequency energy and light energy, the first information may separately indicate the intensity of each energy source. For example, the first information may include "Intensity: -20dBm; Intensity: 20dBm." This indicates that the terminal can collect two energy sources from the environment, one with an intensity of -20dBm and the other with an intensity of 20dBm.

[0124] When the at least one energy includes multiple energies, such as radio frequency energy and light energy, the first information may indicate the total intensity of the multiple energies. For example, the first information may include "Intensity: 10 dBm," indicating that the total intensity of the two energies that the terminal can collect from the environment is 10 dBm.

[0125] In some implementations of this embodiment, the first information may further indicate the duration of the at least one energy, which may also be referred to as duration.

[0126] Optionally, the duration of each type of energy in the at least one type of energy may be indicated separately, or the first information may indicate one duration for all types of energy in the at least one type of energy.

[0127] For example, the duration indicated by the first information may be the duration of the energy with the highest intensity among the at least one energy, may be the shortest duration among the durations corresponding to the at least one energy, may be the average duration of the durations corresponding to the at least one energy, or may be the total duration of the energy type with the highest intensity among the at least one energy.

[0128] For example, if the at least one energy source includes one type of energy, such as radio frequency energy or light energy, the first information may include the following: "Intensity: -20dBm, Duration: 1s," where "s" represents the time unit "seconds." This indicates that the energy intensity of the energy source that the terminal can collect from the environment is -20dBm and has been present for 1 second.

[0129] For example, if the at least one energy source includes multiple energy sources and the first information separately indicates the intensity and duration of each energy source, the first information may include the following: "Intensity: -20dBm, Duration: 1s; Intensity: 20dBm, Duration: 2s." This indicates that, among the multiple energy sources that the terminal can collect from the environment, one has an intensity of -20dBm and has been present for 1 second, and another has an intensity of 20dBm and has been present for 2 seconds.

[0130] For example, if the at least one energy source includes multiple energy sources and the first information jointly indicates the intensity and duration of these multiple energy sources, the first information may include the following: "Intensity: 10dBm, Duration: 1s." This indicates that the total intensity of the multiple energy sources that the terminal can collect from the environment is 10dBm and has been present for 1 second.

[0131] In some implementations of this embodiment, the first information may further indicate the type of each energy in the at least one energy. The type of energy may also be referred to as a category or classification of energy.

[0132] Taking the at least one energy including one type of energy as an example, the first information may include the following content: "Intensity: -20dBm, Type: RF energy." This indicates that RF energy exists in the environment, and the energy intensity is -20dBm.

[0133] Taking the at least one energy including one type of energy as an example, the first information may include the following content: “Intensity: 20 dBm, Type: Light Energy”, which indicates that there is a light source in the environment, and the energy intensity of the light source is 20 dBm.

[0134] For example, if the at least one energy source includes multiple energy sources and the first information separately indicates the intensity and type of each energy source, the first information may include the following: "Intensity: -20dBm, Type: RF Energy; Intensity: 20dBm, Type: Light Energy." This indicates that the terminal can collect both RF energy and light energy from the environment, with the RF energy intensity being -20dBm and the light energy intensity being 20dBm.

[0135] For example, if the at least one energy source includes multiple energy sources and the first information jointly indicates the intensities and types of the multiple energy sources, the first information may include the following: "Intensity: 10dBm, Type: RF energy, light energy." This indicates that the terminal can collect RF energy and light energy from the environment, and the total intensity of the RF energy and light energy is 10dBm.

[0136] In some implementations of this embodiment, the first information indicates the intensity, duration, and type of each energy of the at least one energy.

[0137] For example, if the at least one energy includes one type of energy, the first information may include the following: "Intensity: -20dBm, Duration: 1s, Type: RF Energy." This indicates that RF energy exists in the environment, with an energy intensity of -20dBm and has been present for 1 second.

[0138] For example, if the at least one energy includes one type of energy, the first information may include the following content: "Intensity: 20 dBm, Duration: 1 s; Type: Light Energy." This indicates that there is a light source in the environment, the energy intensity of the light source is 20 dBm, and it has been present for 1 second.

[0139] For example, if the at least one energy source includes multiple energy sources and the first information separately indicates the intensity and type of each energy source, the first information may include the following: "Intensity: -20dBm, Duration: 1s; Type: RF Energy; Intensity: 20dBm, Duration: 1s; Type: Light Energy." This indicates that the terminal can collect RF energy and light energy from the environment, with the RF energy intensity being -20dBm and lasting for 1 second, and the light energy intensity being 20dBm and lasting for 1 second.

[0140] Assuming that the at least one energy source includes multiple energy sources, the first information jointly indicates the intensities of the multiple energy sources. For example, the duration and type of the energy source might include the following: "Intensity: 10dBm, Duration: 1s, Type: RF energy, Light energy." This indicates that the terminal can collect RF energy and light energy from the environment, and the total intensity of the RF energy and light energy is 10dBm, which has been present for 1 second.

[0141] In some implementations of this embodiment, when the at least one type of energy indicated by the first information includes radio frequency energy, the first information may further indicate a frequency band of the radio frequency energy.

[0142] As an example, the first information may include the following content: “Intensity: -20 dBm, Frequency Band: 800-900 MHz.” This indicates that radio frequency energy in the frequency band of 800 MHz to 900 MHz exists in the environment, and the energy intensity is -20 dBm.

[0143] As another example, the first information may include the following content: "Intensity: -20dBm, Duration: 1s, Frequency Band: 800-900MHz." This indicates that radio frequency energy in the frequency band of 800MHz to 900MHz exists in the environment, with an energy intensity of -20dBm and has been present for 1 second.

[0144] As another example, the first information may include the following: "Intensity: -20dBm, Duration: 1s, Frequency Band: 800-900MHz, Type: RF; Intensity: 20dBm, Duration: 1s, Type: Light." This indicates that RF energy in the 800MHz to 900MHz frequency band is present in the environment, with an energy intensity of -20dBm and has been present for 1 second; and that light energy is also present in the environment, with an energy intensity of 20dBm and has been present for 1 second.

[0145] As another example, the first information may include the following: "Intensity 10 dBm, Duration: 1 second, Type: RF, Light, Frequency Band: 800-900 MHz." This indicates that an energy source exists in the environment, the intensity of the energy source is 10 dBm, and the energy source includes light and RF energy of 800-900 MHz, which has been present for 1 second.

[0146] In some implementations of this embodiment, the first information may be carried in a charging request, where the charging request is used to request charging from the network device.

[0147] In some implementations of this embodiment, the network device may calculate the transmission power of the charging signal based on the first information. For example, the transmission power of the charging signal is greater than or equal to the difference between the charging power required by the terminal and the intensity of the ambient energy indicated by the first information.

[0148] In some implementations of this embodiment, the terminal may also report at least one of the following information to the network device: remaining power, maximum energy storage power, desired charging power, or terminal location information. This information may be referred to as charging auxiliary information, or simply auxiliary information.

[0149] In some implementations, the auxiliary information and the first information may be carried in the same message, for example, in a charging request.

[0150] After receiving the information reported by the terminal, the network device can determine the sending power of the charging signal based on the information and the first information. For example, after receiving the remaining power and the ambient energy intensity, the network device can calculate the power of the sending charging signal.

[0151] An example calculation method is as follows: the initial required power of the charging signal is calculated based on the remaining power, and the ambient energy intensity is subtracted from the initial required power to obtain the charging signal power. This shows that network devices, knowing the ambient energy intensity, can save network device resources and only need to compensate for a portion of the energy shortfall.

[0152] Among them, if the first information indicates the total intensity of at least one energy, the ambient energy intensity subtracted from the initial required power may be the total intensity; if the first information separately indicates the intensity of each energy in the at least one energy, the ambient energy intensity subtracted from the initial required power may be the sum of the intensities of all energies in the at least one energy.

[0153] In some implementations of this embodiment, the terminal may measure the intensity of radio frequency energy in the environment through an antenna.

[0154] In some implementations of this embodiment, the terminal may measure the intensity of light energy in the current environment through a solar panel.

[0155] In some implementations of this embodiment, the charging signal may be a wireless radio frequency signal dedicated to providing charging power.

[0156] In some implementations of this embodiment, the terminal may measure the intensity of vibration energy in the current environment through the electrical signal converted by the vibration absorber.

[0157] In some implementations of this embodiment, the terminal may measure the intensity of thermal energy in the current environment by converting the thermal energy into an electrical signal through thermoelectric materials.

[0158] Fig. 4 is a flow chart of a communication method according to another embodiment of the present application. As shown in Fig. 4 , the method may include S410, S415 and S420.

[0159] S410: The terminal sends first information to a network device, where the first information indicates a first intensity, which is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the first information from the terminal.

[0160] This step may refer to S310 and will not be described in detail here.

[0161] S415: The network device sends charging configuration information to the terminal, where the charging configuration information indicates the charging duration and / or charging frequency of the terminal.

[0162] The charging time may be an estimated or preconfigured charging time, which may also be referred to as a charging duration; and the charging frequency may be frequency band information of a charging signal.

[0163] S420: The network device sends a charging signal to the terminal according to the first information. Correspondingly, the terminal receives the charging signal from the network device.

[0164] This step can be referred to S320 and will not be repeated here.

[0165] Some technical effects of this method can refer to the technical effects of the method shown in Figure 3. In addition, the network device indicates the charging time to the terminal, which is beneficial for the terminal to plan the time for the next charging request; the network device indicates the charging frequency to the terminal, which is beneficial for the terminal to adjust the frequency matching range of hardware such as antennas and rectifiers; thereby making charging more efficient, thereby reducing charging time and saving base station resources.

[0166] In some implementations of this embodiment, the charging configuration information indicating the charging duration of the terminal may include: the charging configuration information includes time domain resource information and / or frequency domain resource information allocated for the charging signal. In this implementation, the terminal may estimate the charging duration based on the time domain resource information and may determine the charging frequency range based on the frequency domain resource information.

[0167] It can be understood that the method shown in FIG. 4 may further include one or more steps other than S310 and S320 in the method shown in FIG. 3 .

[0168] Fig. 5 is a flow chart of a communication method according to another embodiment of the present application. As shown in Fig. 5 , the method may include S508, S510, and S520.

[0169] S508: The network device sends second information to the terminal, where the second information is used to determine the resources for the terminal to collect environmental energy. Correspondingly, the terminal receives the second information from the network device.

[0170] The resource from which the terminal collects ambient energy may satisfy the following characteristics: the network device does not send a signal on the resource.

[0171] S510: The terminal sends first information to a network device, where the first information indicates a first intensity, which is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the first information from the terminal.

[0172] This step may refer to S310 and will not be described in detail here.

[0173] S520: The network device sends a charging signal to the terminal according to the first information. Correspondingly, the terminal receives the charging signal from the network device.

[0174] This step may refer to S320 and will not be described again here.

[0175] Some technical effects of this method can refer to the technical effects of the method shown in Figure 3. In addition, this method helps to prevent the energy intensity collected by the terminal from being interfered with by the intensity of the radio frequency signal of the network device, thereby improving the accuracy of the intensity of the ambient energy collected by the terminal, and further better saving the resource energy consumption of the network device.

[0176] In some implementations, the resources from which the terminal collects ambient energy do not include resources in which the network device transmits signals across the entire operating frequency band of the terminal. Alternatively, the network device does not transmit signals on some or all of the frequency domain resources within some time domain resources, and the second information indicates the time-frequency resources and the frequency domain resources. The terminal collects ambient energy information at the resources indicated by the second information.

[0177] In some implementations of this embodiment, the resources used by the terminal to collect ambient energy include multiple time domain resources, where different time domain resources correspond to different frequency domain resources. In other words, the network device disables different frequency bands in different time domain resources. This can reduce the impact of ambient energy measurement or collection on network device services other than charging services.

[0178] For example, if a terminal's energy collection frequency range is large, disabling all frequency bands during certain time slots can severely impact other network services. Therefore, a time-frequency resource pattern is necessary to ensure that the terminal can measure ambient energy across different frequency bands in a time-division manner. This time-frequency resource pattern can be adjusted based on the terminal's energy collection frequency band.

[0179] Figure 6 shows an example of a time-frequency resource pattern. In Figure 6, from the frequency domain, one grid can be a frequency band; from the time domain, one grid can be a time slot.

[0180] As shown in Figure 6, a portion of the frequency band is closed in different time slots, and the terminal can measure in sequence according to the configuration, and finally obtain the total ambient RF energy intensity.

[0181] It is understandable that the above-mentioned time-frequency resource pattern is only an example. When the network equipment does not have much business, you can also choose to turn off all frequency bands in some time slots. Or, when the energy collection frequency band range of the terminal is relatively small, you can turn off the relevant frequency bands in one or several time slots.

[0182] Some implementations of this embodiment may further include S506, where the terminal sends third information to the network device, where the third information is used to instruct the terminal to request the network device to perform radio frequency energy measurement. Alternatively, the third information is used to request the terminal to collect resources for ambient energy, or the third information is a radio frequency energy measurement request, or the third information is used to inform the network device that "the terminal needs to measure ambient energy" or "the terminal needs to measure ambient radio frequency energy."

[0183] In this implementation, the network device may send the second information to the terminal based on the third information.

[0184] Some implementations of this embodiment may further include S504, where the terminal indicates an operating frequency band of the terminal to the network device. For example, the operating frequency band may be an operating frequency band of a rectifier and / or antenna circuit of the terminal, or may be a frequency band at which the terminal collects radio frequency energy.

[0185] Optionally, the terminal indicates its working frequency band to the network device when it needs to measure environmental energy; it can also report its working frequency band to the network device when it accesses the network device, for example, the terminal carries the working frequency band information in the message reporting the terminal capabilities.

[0186] When the terminal indicates its working frequency band to the network device when it needs to measure environmental energy, in some implementations, the indication information of the working frequency band and the third information can be carried in the same message, or the third information also includes the indication information of the terminal's working frequency band.

[0187] It can be understood that in some implementations of this embodiment, S504 and S506 may be included at the same time, or only one of them may be included.

[0188] It can be understood that the method shown in FIG. 5 may further include one or more steps other than S410 and S420 in the method shown in FIG. 4 .

[0189] Due to the randomness of ambient energy, the ambient energy may suddenly increase or decrease during the charging process. At this time, it is necessary to adjust the power intensity of the charging signal in a timely manner. In some embodiments of the present application, the network device can dynamically adjust the charging resources during the charging process. In particular, the network device can adjust the charging resources in a timely manner according to the changes in the ambient energy, thereby achieving more flexible charging resource adjustment and more efficiently saving the charging resources of the network device.

[0190] Fig. 7 is a flow chart of a communication method according to another embodiment of the present application. As shown in Fig. 7 , the method may include S710, S720, S730, and S740.

[0191] S710: The terminal sends first information to a network device, where the first information indicates a first intensity, which is the intensity of at least one type of energy in the environment where the terminal is located. Accordingly, the network device receives the first information from the terminal.

[0192] This step may refer to S310 and will not be described again here.

[0193] S720: The network device sends a charging signal to the terminal according to the first information. Correspondingly, the terminal receives the charging signal from the network device.

[0194] This step can be referred to S320 and will not be described again here.

[0195] S730: The terminal sends fourth information to the network device, where the fourth information indicates a second intensity, where the second intensity is the intensity of at least one type of energy in the environment where the terminal is located. Accordingly, the network device receives the fourth information from the terminal.

[0196] This step may refer to S310, for example, the first intensity in S310 is replaced by the first intensity, and the first information therein is replaced by the fourth information.

[0197] S740: The network device sends a charging signal to the terminal according to the second information. Correspondingly, the terminal receives the charging signal from the network device.

[0198] This step may refer to S320, for example, replacing the first information in S320 with the fourth information.

[0199] In this method, the terminal updates the energy intensity of its environment to the network device, and the network device can adjust the charging resources in time according to the changes in the environmental energy, thereby achieving more flexible charging resource adjustment and more efficiently saving the charging resources of the network device.

[0200] In this embodiment, the time when the terminal collects the first intensity can be called the first time, and the time when the terminal collects the second intensity can be called the second time. The second time can be located after the first time.

[0201] In some implementations of this embodiment, the resources used to transmit the fourth information can be interspersed with the time-frequency resources used to transmit the charging signal sent by the network device based on the first information. Figure 8 is an exemplary diagram of time-frequency resources for updating environmental energy information according to an embodiment of the present application.

[0202] Optionally, the resources used to transmit the fourth information may be predetermined by the communication protocol, or may be predefined between the network device and the terminal, or may be configured by the network device to the terminal through information.

[0203] When the network device configures resources for transmitting the fourth information to the terminal through information, in some implementations, the network device may configure the resources for transmitting the fourth information in the configuration information for first configuring the transmission resources of the charging signal for the terminal.

[0204] For a frequency division duplexing (FDD) system, in some implementations, the uplink resource used to transmit the fourth information and the charging resource may be in the same time slot.

[0205] For a time division duplexing (TDD) system, in some implementations, charging resources and uplink resources are in different time slots.

[0206] When the fourth information indicates the second strength, in some implementations, the fourth information may indicate a difference between the second strength and the first strength, thereby reducing transmission overhead.

[0207] As an example, if the first intensity is 10 dBm and the second intensity is 5 dBm, then an example of the fourth information is “Intensity: -5 dB”, which means that the current ambient energy is 5 dB less, indicating that the ambient energy has become weaker.

[0208] As another example, if the first intensity is 10 dBm and the second intensity is 5 dBm, then an example of the fourth information is “Intensity: 5 dB.” This means that the current ambient energy has increased by 5 dB, indicating that the ambient energy has become stronger.

[0209] In this embodiment, S710 and S720 can be collectively referred to as one environmental energy reporting phase, and S730 and S720 can be collectively referred to as one environmental energy reporting phase. In a charging process between a terminal and a network device, the first environmental energy reporting phase is referred to as the initial phase, and subsequent environmental energy reporting phases are referred to as update phases.

[0210] In an implementation manner in which the fourth information may indicate a difference between the second strength and the first strength, the network device may determine whether the current strength is an absolute strength value or a relative strength difference according to whether it is the first phase or the update phase.

[0211] In some implementations of this embodiment, during the update phase, the terminal may report the fourth information only if the absolute value of the difference between the second intensity and the first intensity is greater than or equal to a threshold. Alternatively, the terminal may not report the fourth information if the absolute value of the difference between the second intensity and the first intensity is less than the threshold.

[0212] In some implementations, the threshold may be agreed upon between the network device and the terminal.

[0213] As an example, when the terminal accesses a network device, the network device may configure the threshold through a radio resource control (RRC) message.

[0214] As another example, after the terminal sends a charging request to the network device, the network device configures the threshold value via a downlink message. For example, the threshold value and the charging configuration information may be sent to the terminal in the same message.

[0215] The terminal reports the fourth information only when the absolute value of the difference between the second intensity and the first intensity is greater than or equal to the threshold, which can implicitly inform the network device of the current environmental energy change.

[0216] As an example, the network device and the terminal agree that the terminal will report the environmental energy only when the energy change is greater than 5dB or less than -5dB. This can save the terminal's power and reduce the complexity of interaction.

[0217] For example, the environmental energy intensity in the initial phase is 10 dBm, and the environmental energy intensity in the update phase is 3 dBm. Then the energy change is -7 dBm. The energy change is less than the -5 dB threshold and should be reported to the network device.

[0218] It can be understood that the method shown in FIG. 7 may further include one or more steps other than S510 and S520 in the method shown in FIG. 5 .

[0219] Figure 9 is a flow chart of a communication method according to another embodiment of the present application. As shown in Figure 9 , the method may include S910 , S920 , S930 , and S940 .

[0220] S910: The terminal sends first information to a network device, where the first information indicates a first intensity, which is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the first information from the terminal.

[0221] This step may refer to S310 and will not be described again here.

[0222] S920: The network device sends a charging signal to the terminal according to the first information. Correspondingly, the terminal receives the charging signal from the network device.

[0223] This step can be referred to S320 and will not be described again here.

[0224] S930: The terminal sends fourth information to the network device, where the fourth information indicates a second intensity, where the second intensity is the intensity of at least one type of energy in the environment where the terminal is located. Accordingly, the network device receives the fourth information from the terminal.

[0225] This step may refer to S310, for example, the first intensity in S310 is replaced by the first intensity, and the first information therein is replaced by the fourth information.

[0226] S940: The network device sends sixth information to the terminal, where the sixth information indicates that charging is completed.

[0227] In this embodiment, the network device receives the updated environmental energy information and can make further decisions. If it finds that the current environmental energy is very strong and the network device no longer needs to actively charge, it can send a termination message to the terminal to end the charging process, thereby saving the network device's charging resources.

[0228] It is understood that the method shown in Figure 9 may also include one or more steps other than S710, S720, and S730 in the method shown in Figure 7. For example, if the second strength is less than or equal to the strength threshold, the network device may execute S740.

[0229] Figure 10 is a flow chart of a communication method according to another embodiment of the present application. As shown in Figure 10 , the method may include S1010, S1020, and S1030.

[0230] S1010: A terminal sends first information to a network device, where the first information indicates a first intensity, which is the intensity of at least one type of energy in an environment where the terminal is located. Accordingly, the network device receives the first information from the terminal.

[0231] This step may refer to S310 and will not be described again here.

[0232] S1020: The network device sends a charging signal to the terminal according to the first information. Correspondingly, the terminal receives the charging signal from the network device.

[0233] This step can be referred to S320 and will not be described again here.

[0234] S1030: The terminal sends seventh information to the network device, where the seventh information indicates that charging is completed.

[0235] In this embodiment, if the terminal finds that the current environmental energy is very strong and the network device no longer needs to be charged, it can send a message to terminate charging to the network device to end the process, thereby saving charging resources of the network device.

[0236] It can be understood that the method shown in FIG. 10 may further include one or more steps other than S910 , S920 and S930 in the method shown in FIG. 9 .

[0237] It should be understood that, in this application, indication includes direct indication (also known as explicit indication) and implicit indication. Direct indication of information A refers to including information A; implicit indication of information A refers to indicating information A through the correspondence between information A and information B and the direct indication of information B. The correspondence between information A and information B can be predefined, pre-stored, pre-burned, or pre-configured.

[0238] It should be understood that, in this application, information C is used to determine information D, which includes both information D being determined solely based on information C and information D being determined based on information C and other information. Furthermore, information C can also be used to determine information D indirectly, for example, where information D is determined based on information E, and information E is determined based on information C.

[0239] In addition, in each embodiment of the present application, "device A sends information A to device B" can be understood as the destination of the information A or the intermediate device in the transmission path between the destination and the device B, which may include directly or indirectly sending information to device B. "Device B receives information A from device A" can be understood as the source of the information A or the intermediate device in the transmission path between the source and the device A, which may include directly or indirectly receiving information from device A. The information may undergo necessary processing between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be elaborated here.
