Base stations, as the core infrastructure of wireless communication networks, can transmit wireless energy to terminal devices through specific technologies such as electromagnetic induction, magnetic field resonance, or radio waves. For example, base stations can achieve efficient and stable wireless energy transfer to terminal devices by adjusting the parameters of their emitted electromagnetic waves (such as frequency and power).

[0054] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0055] In the description of this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can represent A or B. "And / or" in this application merely describes the relationship between related objects, indicating that three relationships can exist.

For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple. Additionally, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and that "first," "second," etc., are not necessarily different. It should be understood that in this application, descriptions such as "in the case of," "if," "when," "if," etc., can be used interchangeably. In the embodiments of this application, at least one can also be described as one or more, and multiple can be two, three, four, or more; this application does not impose any limitations.

[0056] In this application embodiment, wireless charging can also be abbreviated as "charging," "energy transfer," "charging," "wireless energy transfer," "wireless charging," "wireless energy transmission," "radio frequency energy transmission," "radio frequency energy transfer," "radio frequency charging," "radio frequency charging," etc., and such descriptions do not constitute a limitation on the embodiments of this application. In the following description, "charging" and "wireless charging" will be used as the main terms.

[0057] For example, the charging signal may also be referred to as "power transfer signal," "charging signal," "wireless charging signal," "wireless power transfer signal," "wireless charging signal," "energy signal," etc., and such description does not constitute a limitation on the embodiments of this application. In the following description, "charging signal" and "wireless charging signal" will be used as the main terms.

[0058] This application's embodiments target protocol frameworks such as LTE (Long Term Evolution) or NR (New Radio Access Technology (5G)) and can be applied to various mobile communication scenarios. Figure 1 is a schematic diagram of an application scenario provided by an embodiment of this application. It should be understood that the application scenario shown in Figure 1 is merely an example and is not intended to limit this application.

[0059] As shown in Figure 1a, in this scenario, the base station 110 and the user equipment (UE) have a point-to-point single connection. In this scenario, the base station 110 can wirelessly charge the user equipment 120, that is, the base station 110 directly sends a charging signal to the user equipment 120.

[0060] As shown in Figure 1b, in this scenario, the connection between base station 110 and user equipment 120 is a multi-hop single connection, meaning that the connection between base station 110 and user equipment 120 is established through multiple relay devices. Base station 110, multiple relay base stations, and user equipment 120 are connected sequentially. In this scenario, base station 110 wirelessly charges user equipment 120 sequentially through multiple relay base stations. For example, base station 110 sends a wireless charging signal to first relay base station 130, first relay base station 130 sends the wireless charging signal to second relay base station 140, and second relay base station 140 sends the wireless charging signal to user equipment 120.

[0061] As shown in Figure 1c, in this scenario, the connection between base station 110 and user equipment 120 is multi-hop multi-connection, meaning that multiple relay devices connect base station 110 and user equipment 120, and these relay base stations are connected to both base station 110 and user equipment 120 respectively. In this scenario, base station 110 wirelessly charges user equipment 120 through these multiple relay base stations. For example, base station 110 sends wireless charging signals to a third relay base station 150 and a fourth relay base station 160, and the third relay base station 150 and the fourth relay base station 160 then send the wireless charging signals to user equipment 120.

[0062] As shown in diagram d of Figure 1, in this scenario, there is dual connectivity (DC) between base station 110, base station 170, and user equipment 120. That is, base station 110 and base station 170 are each connected to user equipment 120, and base station 110 and base station 170 are interconnected. In this scenario, base station 110 wirelessly charges user equipment 120 through multiple relay base stations. For example, base station 110 can send wireless charging signals to user equipment 120, and base station 170 can also send wireless charging signals to user equipment 120. Additionally, base station 110 can also send wireless charging signals to base station 170.

[0063] For example, base station 110 in Figure 1 can be a macrocell. Macrocells are suitable for large-area wireless coverage and are the basic structure of the network, but they have blind spots and hot spots. Base station 170, on the other hand, can be a microcell. Microcells serve as a supplement and extension to macrocells, mainly used to improve coverage and capacity, and solve blind spot and hot spot problems. They have the characteristics of low transmission power, small coverage radius, and flexible installation.

[0064] It should be understood that Figure 1 is merely exemplary and does not limit the network architecture applicable to this application. Any network architecture in a cellular network where any network device wirelessly charges other devices is applicable to this application. That is, the application scenarios of this application include, but are not limited to, base stations wirelessly charging user equipment, base stations wirelessly charging each other, base stations wirelessly charging relay base stations, relay base stations wirelessly charging user equipment, multiple base stations wirelessly charging one user equipment, and multiple base stations wirelessly charging multiple user equipment. In other words, this application can be applied to scenarios where any one or more network devices wirelessly charge one or more user devices.

[0065] The wireless communication system provided in this application includes communication devices, which can communicate with each other using air interface resources.

[0066] For example, in a wireless communication system, communication devices may include network devices and terminal devices, and air interface resources may include at least one of time-domain resources, frequency-domain resources, code resources, and spatial resources. In the scenario shown in Figure 1, both base station 110 and user equipment 120 are communication devices, where base station 110 is a network device and user equipment 120 is a terminal device.

[0067] The terminal device involved in the embodiments of this application can also be called a terminal. The terminal device can be a device with wireless transceiver function. The terminal device can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; the terminal device can also be deployed on water (such as ships); the terminal device can also be deployed in the air (such as airplanes, balloons and satellites).

[0068] Terminal devices can be user equipment, including handheld devices, in-vehicle devices, wearable devices, or computing devices with wireless communication capabilities. For example, a user equipment can be a mobile phone, a tablet computer, or a computer with wireless transceiver capabilities. Terminal devices can also be virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in autonomous driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0069] In this application embodiment, the device for implementing the functions of the terminal device can be a terminal; it can also be a device capable of supporting the terminal in implementing the functions. This device can be installed in the terminal, for example, a chip system installed in the terminal. In this application embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices. In the technical solutions provided in this application embodiment, the device for implementing the functions of the terminal is the terminal, and the terminal is the user, as an example, to describe the technical solutions provided in this application embodiment.

[0070] The network devices involved in the embodiments of this application include access network devices, such as base stations (BS). A base station can be a device deployed in a wireless access network that can wirelessly communicate with terminals. Base stations may take various forms, such as macro base stations, micro base stations, relay base stations, and access points. For example, the base station involved in the embodiments of this application can be a 5G base station or an evolved Node B (eNB) in LTE. The 5G base station can also be called a transmission reception point (TRP) or a 5G base station (Next-Generation Node B, gNB). In the embodiments of this application, the apparatus for implementing the functions of the network device can be the network device itself; it can also be an apparatus that supports the network device in implementing the functions. This apparatus can be installed in the network device, for example, a chip system installed in the network device. In the embodiments of this application, the chip system can be composed of chips or can include chips and other discrete components. In the technical solutions provided in the embodiments of this application, the apparatus for implementing the functions of the network device is a network device, and the network device is a base station, as an example, to describe the technical solutions provided in the embodiments of this application.

Wireless communication / wireless charging between communication devices can include: wireless communication / wireless charging between network devices and terminals, wireless communication / wireless charging between network devices, and wireless communication / wireless charging between terminals.

[0072] In the embodiments of this application, the term "wireless communication" can also be abbreviated as "communication," and the term "communication" can also be described as "data transmission" or "information transmission."

[0073] Figure 2 is a schematic diagram of an O-RAN architecture and a schematic diagram of a RAN chip architecture.

[0074] As shown in Figure 2a, the O-RAN includes a core network (CN) device 210, an access network (RAN) device 220, and user equipment 230. The access network device 220 can be an eNB (Evolved Node B), a gNB (Next-Generation Node B), or a next-generation access network device. The access network device 220 communicates with the core network device 210 via a backhaul link and with the user equipment 230 via an air interface.

[0075] As shown in Figure 2a, the access network device 220 may include a baseband unit (BBU) 221 and a radio unit (RU) 222. The baseband unit 221 in the access network device 220 communicates with the core network device 210 through a backhaul link, and the radio unit 222 in the access network device 220 communicates with at least one user equipment through an air interface.

[0076] For example, baseband unit 221 communicates with at least one radio frequency unit 222 via a fronthaul link. Baseband unit 221 and radio frequency unit 222 may or may not be co-located.

[0077] As shown in Figure 2a, the baseband unit 221 includes at least one control unit (CU) 223 and at least one distributed unit (DU) 224, and the at least one control unit 223 and the at least one distributed unit 224 can communicate through at least one midhaul link.

[0078] Figure 2b shows a common RAN chip architecture. As shown in Figure 2b, the RAN chip is divided into CU, DU, and RU. The midhaul interface carries traffic between the CU and DU, the backhaul interface carries traffic between the CU and core network equipment, and the fronthaul (FH) interface carries traffic between the DU and RU. The CU is a platform that performs upper-layer L2 and L3 functions, the DU performs L1 and some L2 functions, and the RU performs L1 computation and RF digital functions. An integrated DU can include the functions of both the DU and RU. Wherein:

[0079] The CU and / or DU hardware includes a chassis platform, motherboard, peripherals, and cooling system. The motherboard contains processing units, memory, internal I / O interfaces, and external connection ports. Its hardware accelerators are designed with interfaces, and hardware functional components include: storage for software, hardware, and system debugging interfaces, and a single-board management controller.

[0080] The CU's hardware accelerator can be an FPGA (Field-Programmable Gate Array) based accelerator, a GPU (Graphics Processing Unit) based accelerator, or other accelerators. The CU's hardware accelerator supports interconnection with x86 or non-x86 processors. The DU's processor can be an x86 processor or an ARM (Advanced RISC Machines) based processor.

[0081] A DU system is typically implemented using a multi-core processor and one or more hardware accelerators. Parts of the DU protocol stack can be implemented in software running on the multi-core processor, while computationally intensive L1 and L2 functions can be offloaded to the hardware accelerator; alternatively, all L1 functions can be offloaded to the hardware accelerator, while other protocol stack components are implemented in software running on the processor; or the entire protocol stack can be implemented in software running on the processor. The DU's hardware accelerator can be an FPGA-based accelerator, a GPU-based accelerator, or another type of accelerator, and it supports interconnection with x86 or non-x86 processors. The DU's processor can be an x86 processor or an ARM-based processor. Similarly, the accelerator has a multi-channel PCIe interface pointing to the processor and external connections via GbE (Gigabit Ethernet).

[0082] An RU, or O-RU, comprises three parts: a RAN FH processing unit, a data processing unit (DPU), and an RF (Radio Frequency) processing unit. Among them:

[0083] The RAN FH processing unit receives eCPRI frames from the O-RAN's Fronthaul and performs Fronthaul interface operations, the lowest level L1 (coding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping. The RAN FH processing unit can be implemented as a CPU, FPGA, or ASIC (Application-Specific Integrated Circuit).

[0084] The DPU, or Data Processing Unit of the O-RU, performs synchronization, DDC (Digital Down-Conversion in UL), DUC (Digital Up-Conversion in DL), CFR (Counterfactual Regret Minimization), and DPD (Digital Pre-Distortion). It improves power amplifier efficiency by reducing PAPR (Peak-to-Average Power Ratio) / ACLR (Adjacent Channel Leakage Ratio) at the RF front end. The DPU can be implemented as an FPGA or ASIC.

[0085] The O-RU's RF processing unit includes a transceiver module, up / down converters, power amplifiers (PA), low-noise amplifiers (LNA), and Tx / Rx filters. All conversions between the analog and digital domains (DAC (Digital-to-Analog Converter) and ADC (Analog-to-Digital Converter)) are performed. For example, RF sampling, frequency conversion using RF, IF, and LO mixing during up-conversion and down-conversion, are all performed within the transceiver module. It is understood that the physical and logical partitioning within the RF processing unit does not require specific boundaries.

[0086] The RF processing unit in Figure 2 is connected to the antenna. The RF processing unit is responsible for converting the baseband signal into a radio frequency signal for wireless transmission through the antenna. It is also responsible for converting the received radio frequency signal into a baseband signal for DPU processing.

[0087] The wireless charging method provided in this application can be applied to scenarios where base station 110 wirelessly charges a target terminal device through terminal device 120. In this scenario, the network device in this application can be base station 110, the first terminal device can be terminal device 120, and the target terminal device can be other terminal devices connected to terminal device 120. That is, wireless charging of the target terminal device by base station 110 is achieved through the interaction between terminal device 120 and base station 110.

[0088] It should be understood that since charging signals can be wireless communication signals, such as electromagnetic waves or radio frequency signals, wireless charging signals and wireless communication signals can be the same type of signal, differing only in their function. The target terminal device can receive both wireless communication signals and wireless charging signals sent by the network device via its antenna. The target terminal device can convert the received electromagnetic wave / radio frequency signals into DC voltage: when the signal sent by the network device is a charging signal, the converted DC voltage is greater than or equal to the rectifier circuit's turn-on voltage, allowing the target terminal device to store energy for wireless charging; when the signal sent by the network device is merely a wireless communication signal, the converted DC voltage is less than the rectifier circuit's turn-on voltage, preventing the target terminal device from storing energy and thus preventing wireless charging.

[0089] The wireless charging method provided in this application will be described in detail below with reference to the corresponding flowcharts. It is understood that the first terminal device in the illustrative flowchart can also be a chip, chip system, or processor that supports the implementation of this method on the first terminal device, or it can be a logic module or software that can implement all or part of the functions of the first terminal device. Similarly, the target terminal device in the illustrative flowchart can also be a chip, chip system, or processor that supports the implementation of this method on the target terminal device, or it can be a logic module or software that can implement all or part of the functions of the target terminal device. Likewise, the network device in the illustrative flowchart can also be a chip, chip system, or processor that supports the implementation of this method on the network device, or it can be a logic module or software that can implement all or part of the functions of the network device.

[0090] To facilitate understanding, the following explanation uses a mobile phone as an example to illustrate the process of interface changes during user interaction between the terminal device and the user.

[0091] Referring to Figure 3, it is a schematic diagram of interface changes of a terminal device provided in an embodiment of this application.

[0092] Figure 3a shows the control center interface of the mobile phone, which can be accessed by the user by swiping down from the upper right side of the phone screen. The interface shown in Figure 3a displays a switch control 301, which is in an unselected state. In this state, the wireless charging switch of the target terminal device is off (or the wireless charging function is unavailable).

[0093] In this embodiment of the application, the wireless charging switch of the target terminal device is in the off state (or the wireless charging function is unavailable). This can be understood as: the target terminal device has not yet been identified by the user as a device that needs to be wirelessly charged, or the network device has not been instructed to send a charging signal to the target terminal device.

[0094] As shown in Figure 3a, after the user clicks the switch control 301, the display interface jumps from Figure 3a to Figure 3b. As shown in Figure 3b, the display state of the switch control 301 in this interface differs from that in Figure 3a. In Figure 3b, the switch control 301 is displayed as selected, indicating that the wireless charging switch of the target terminal device is on (or the wireless charging function is available).

[0095] In this embodiment of the application, the wireless charging switch of the target terminal device is in the open state (or the wireless charging function is available). This can be understood as: the target terminal device is determined by the user to be a device that needs to be wirelessly charged, or the network device is instructed to send a charging signal to the target terminal device.

[0096] It is understandable that the target terminal device is the terminal device that the user wants to wirelessly charge. The user's operation of clicking the switch control 301 in Figure 3a is the operation of turning on the wireless charging switch of the target terminal device (or the operation of turning on the wireless charging function). Specifically, after the user clicks the switch control 301, the mobile phone sends an instruction information to the network device, and the network device sends a charging signal to the target terminal device according to the instruction information.

[0097] It is understood that in the embodiment shown in Figure 3, when the mobile phone displays the display interface shown in Figure 3b, the target terminal device may include one or more devices. When the target terminal device includes one device, the device may be the mobile phone itself or any other terminal device connected to the mobile phone. When the target terminal device includes multiple devices, the target terminal device may be any multiple devices among the mobile phone itself and other terminal devices connected to the mobile phone, that is, the multiple devices may include the mobile phone itself or may not include the mobile phone itself.

[0098] For example, other terminal devices connected to the mobile phone can be Bluetooth headsets, smartwatches, tablets, etc., and this application embodiment does not limit the specific type of other terminal devices.

[0099] In the display interface shown in Figure 3b, a speed control 302 is also displayed. The speed control 302 includes a slider 303 and two icons 304. As the user's finger slides on the slider 303, the display state of the slider 303 changes, and different display states of the slider 303 correspond to different charging speeds. Specifically, the length of the shaded portion of the slider 303 is different in different display states. The longer the shaded portion, the higher the charging speed; the shorter the shaded portion, the lower the charging speed. As shown in Figure 3b, after the user's finger slides on the speed control 302 from left to right, the display interface jumps from Figure 3b to Figure 3c.

[0100] As shown in Figure 3c, the speed control 302 displayed in this interface is basically the same as the speed control 302 shown in Figure 3b. The speed control 302 shown in Figure 3c includes a slider 303 and two icons 304. The difference lies in the length of the shaded portion of the slider 303. The length of the shaded portion of the slider 303 shown in Figure 3c is greater than the length of the shaded portion of the slider 303 shown in Figure 3b. When the display interface shown in Figure 3b switches to the display interface shown in Figure 3c, the charging speed of the target terminal device increases.

[0101] It is understandable that when a user slides from right to left on the speed control 302, if the length of the shaded part in the slider 303 decreases, the charging speed of the target terminal device will decrease.

[0102] In some embodiments, if a user clicks the switch control 301 in Figure 3b or Figure 3c, the displayed interface will jump from Figure 3b or Figure 3c to Figure 3a, and the wireless charging switch of the target terminal device will be turned off (or the wireless charging function of the target terminal device will be turned off). Specifically, in the interface shown in Figure 3b or Figure 3c, after the user clicks the switch control 301, the mobile phone sends an instruction message to the network device. Upon receiving this instruction message, the network device stops sending charging signals to the target terminal device.

[0103] Referring to Figure 4, this is a schematic diagram of the interface changes of a terminal device provided in an embodiment of this application. The display interface shown in Figure 4a is basically the same as the display interface shown in Figure 3a. A switch control 401 is displayed in this interface. The switch control 401 shown in Figure 4a is basically the same as the switch control 301 shown in Figure 3a. Therefore, the description of the switch control 301 in Figure 3a above can be referred to, and will not be repeated here. As shown in Figure 4a, after the user clicks the switch control 401, the display interface jumps from Figure 4a to Figure 4b.

[0104] As shown in Figure 4b, the display state of the switch control 401 in this interface differs from that shown in Figure 4a. In Figure 4b, the switch control 401 is displayed as selected, indicating that the wireless charging switch of the target terminal device is in the on state. The switch control 401 shown in Figure 4b is essentially the same as the switch control 301 shown in Figure 3b; therefore, the description of the switch control 301 in Figure 3b can be referred to earlier, and will not be repeated here.

[0105] In the display interface shown in Figure 4b, a speed control 402 is also displayed. Speed ​​control 402 differs from speed control 302 shown in Figure 3. As shown in Figure 4b, speed control 402 includes four circular icons arranged horizontally. Each of the four circular icons corresponds to a charging speed. The word "Slow" is displayed to the left of the four circular icons, and the word "Fast" is displayed to the right. The radius of the circular icons increases from left to right; the larger the radius, the greater the corresponding charging speed. The four circular icons are: Circular Icon 403, Circular Icon 404, Circular Icon 405, and Circular Icon 406. In Figure 4b, the four circular icons are displayed in the same state, indicating that the charging speed of the terminal device is zero. As shown in Figure 4b, after the user clicks on Circular Icon 405, the display interface jumps from Figure 4b to Figure 4c.

[0106] As shown in Figure 4c, the speed control 402 displayed in this interface is basically the same as the speed control 402 shown in Figure 4b, except for the display state of the circular icon 405. Compared to Figure 4b, the color of the circular icon 405 in Figure 4c changes, while the colors of the other three circular icons remain unchanged. When the display interface shown in Figure 4b transitions to the display interface shown in Figure 4c, the charging speed of the target terminal device becomes the charging speed corresponding to the circular icon 405.

[0107] It is understandable that if a user clicks on circular icon 403, circular icon 404, or circular icon 406 in Figure 4c, the color of the clicked circular icon changes, while the color of circular icon 405 reverts to the color shown in Figure 4b. The charging speed of the target terminal device changes to the charging speed corresponding to the clicked circular icon.

[0108] In some embodiments, if a user clicks the switch control 401 in Figure 4b or Figure 4c, the display interface will jump from Figure 4b or Figure 4c to Figure 4a, and the wireless charging switch of the target terminal device will be turned off. That is, the user's operation of clicking the switch control 401 in Figure 4b or Figure 4c is the operation of turning off the wireless charging switch of the target terminal device (or the operation of turning off the wireless charging function).

[0109] It should be understood that the speed control 302 in the embodiment shown in Figure 3 and the speed control 402 in the embodiment shown in Figure 4 are examples of speed controls and are not intended to limit the speed controls. Those skilled in the art can also use other methods to display speed controls, and this application does not enumerate them.

[0110] It is understood that the embodiments of this application only describe in detail the differences between Figure 4 and Figure 3. Other contents not specifically described can be referred to the description of Figure 3 above, and will not be repeated here.

[0111] Referring to Figure 5, this is a schematic diagram of the interface changes of a terminal device provided in an embodiment of this application. The display interface shown in Figure 5a is basically the same as the display interface shown in Figure 3a. The switch control 501 shown in Figure 5a is basically the same as the switch control 301 shown in Figure 3a. Therefore, the description of the switch control 301 in Figure 3a above can be referred to, and will not be repeated here. As shown in Figure 5a, the switch control 501 is displayed in this interface. After the user clicks the switch control 501, the display interface jumps from the one shown in Figure 5a to the one shown in Figure 5b.

[0112] As shown in Figure 5b, the display state of the switch control 501 in this interface differs from that shown in Figure 5a. In Figure 5b, the switch control 501 is displayed as selected, indicating that the wireless charging switch of the target terminal device is in the on state. The switch control 501 shown in Figure 5b is essentially the same as the switch control 301 shown in Figure 3b; therefore, the description of the switch control 301 in Figure 3b can be referred to earlier.

[0113] The interface shown in Figure 5b also displays a speed control 502, which includes a slider 503 and two icons 504. The speed control 502 in Figure 5b is essentially the same as the speed control 302 in Figure 3b; therefore, the description of the speed control 302, slider 303, and two icons 304 in Figure 3b can be referred to earlier, and will not be repeated here.

[0114] In the interface shown in Figure 5b, a mode box 505 is also displayed, containing three different mode controls: a "Health Mode" control 506, a "High-Speed ​​Mode" control 507, and a "Custom Mode" control 508. Each of these three mode controls corresponds to a charging speed. In Figure 5b, all three mode controls are unselected. When one of the three mode controls is selected, the charging speed of the target terminal device is the charging speed corresponding to that mode control.

[0115] It is understood that the pattern box 505 and the pattern control displayed in the pattern box 505 in Figure 5b are merely examples. In other embodiments, the name and number of pattern controls can be changed as needed, which will not be elaborated here.

[0116] As shown in Figure 5b, after the user clicks the "Speed ​​Mode" control 507, the display interface jumps from Figure 5b to Figure 5c.

[0117] As shown in Figure 5c, the display interface includes a switch control 501, a speed control 502, and a mode box 305. The speed control 502 includes a slider 503 and two icons 504. The mode box 505 displays a "Health Mode" control 506, a "Speed ​​Mode" control 507, and a "Custom Mode" control 508. Figure 5c differs from Figure 5b in that the display states of the slider 503 and the "Speed ​​Mode" control 507 are different. In Figure 5c, the "Speed ​​Mode" control 507 is selected, while in Figure 5b, it is unselected. The length of the shaded portion of the slider 503 in Figure 5c is greater than that in Figure 5b. When the phone displays the interface shown in Figure 5c, the target terminal device is in "Speed ​​Mode," and its charging speed is at its maximum. As shown in Figure 5c, after the user clicks the "Custom Mode" control 508, the display interface jumps from Figure 5c to Figure 5d.

[0118] As shown in Figure 5d, the display interface includes a switch control 501, a speed control 502, and a mode box 505. The speed control 502 includes a slider 503 and two icons 504. The mode box 505 displays a "Health Mode" control 506, a "Speed ​​Mode" control 507, and a "Custom Mode" control 508. Figure 5d differs from Figure 5c in that the length of the shaded portion in the slider 503 is different, indicating the different selected mode controls. In Figure 5d, the "Custom Mode" control 508 is selected, while the "Speed ​​Mode" control 507 is unselected; whereas in Figure 5c, the "Speed ​​Mode" control 507 is selected, and the "Custom Mode" control 508 is unselected. The length of the shaded portion of slider 503 shown in Figure 5d is shorter than the length of the shaded portion of slider 503 shown in Figure 5c. When the mobile phone displays the interface shown in Figure 5d, the target terminal device corresponds to "Custom Mode". At this time, the charging speed of the target terminal device is the charging speed corresponding to the "Custom Mode" control 508. That is, after the user clicks the mode control, the state of the mode control and the state of the speed control change synchronously. The user can quickly set the charging speed of the target terminal device through the mode control.

[0119] As shown in Figure 5d, after the user long-presses the "Custom Mode" control 508, the display interface jumps from Figure 5d to Figure 5e. As shown in Figure 5e, this display interface uses the display interface of Figure 5d as the background and displays a floating frame 509. The floating frame 509 displays "Custom Mode" adjustment controls, including an increase button 510, a decrease button 511, and a charging speed value 512. The charging speed value 512 represents the charging speed corresponding to "Custom Mode"; the larger the value of charging speed 512, the greater the charging speed corresponding to "Custom Mode". The user can adjust the charging speed 512 by clicking the increase button 510 or the decrease button 511. The floating frame 509 also displays a close control 513. If the user clicks the close control 513 in the display interface shown in Figure 5d, the display interface will jump from Figure 5e to Figure 5d.

[0120] As shown in Figure 5c, when a user slides their finger from right to left on slider 503, the display interface transitions from Figure 5c to Figure 5f. Figure 5f shows a switch control 501, a speed control 502, and a mode box 305. The speed control 502 includes slider 503 and two icons 504. The mode box 505 displays a "Health Mode" control 506, a "Speed ​​Mode" control 507, and a "Custom Mode" control 508. Figure 5f differs from Figure 5c in that the display states of slider 503 and the "Speed ​​Mode" control 507 are different. In Figure 5f, all three mode controls are in an unselected state, while in Figure 5b, the "Custom Mode" control 508 is selected. The length of the shaded portion of slider 503 in Figure 5f is shorter than the length of the shaded portion of slider 503 in Figure 5c. As the user slides their finger, the length of the shaded portion in slider 503 gradually decreases, and the display state of the "Custom Mode" control 508 changes from selected to unselected. In other words, after the user changes the length of the shaded portion in slider 503, the state of the mode control changes accordingly.

[0121] It is understood that the embodiments of this application only describe in detail the differences between Figure 5 and Figure 3. Other contents not specifically described can be referred to the description of Figure 3 above, and will not be repeated here.

[0122] Referring to Figure 6, this is a schematic diagram of the interface changes of a terminal device provided in an embodiment of this application. The display interface shown in Figure 6a is basically the same as the display interface shown in Figure 3a. The switch control 601 shown in Figure 6a is basically the same as the switch control 301 shown in Figure 3a. Therefore, the description of the switch control 301 in Figure 3a above can be referred to, and will not be repeated here. As shown in Figure 6a, the switch control 601 is displayed in this interface. After the user clicks the switch control 601, the display interface jumps from the one shown in Figure 6a to the one shown in Figure 6b.

[0123] As shown in Figure 6b, the display interface in Figure 6b is basically the same as that in Figure 5b. This display interface shows a switch control 601, a speed control 602, and a mode box 605. The switch control 601 is in the selected state. The speed control 602 includes a slider 603 and two icons 604. The mode box 605 displays a "Health Mode" control 606, a "Speed ​​Mode" control 607, and a "Custom Mode" control 608. The switch control 601 and speed control 602 shown in Figure 6b are basically the same as those shown in Figure 5b. Therefore, the description of the switch control 501 and speed control 502 in Figure 5b can be referred to earlier.

[0124] In the display interface shown in Figure 6b, the “Health Mode” control 606 in the mode box 605 is selected. In the embodiment shown in Figure 6, when the user clicks the switch control 601 shown in Figure 6a, the charging mode defaults to “Health Mode”, and the charging speed displayed by the slider 603 is the charging speed corresponding to the “Health Mode” control 606.

[0125] As shown in Figure 6b, after the user long-presses the switch control 601, the display interface changes from Figure 6b to Figure 6c. As shown in Figure 6c, this display interface uses the interface from Figure 6b as its background and displays a floating frame 609. The floating frame 609 displays three device icons: device icon 610, watch icon 611, and headphone icon 612, from left to right. Device icon 610 is selected, while watch icon 611 and headphone icon 612 are not selected. It can be understood that the selected device icon corresponds to the target terminal device capable of wireless charging. The user can click on the device icons in the floating frame 609 to switch the display status of the device icons, thereby selecting the target terminal device.

[0126] In other embodiments, the selection of the target terminal device can be achieved in other ways. For example, a selection box can be provided below each icon. When a "√" is displayed in the selection box below the device icon, it indicates that the corresponding device is a target terminal device capable of wireless charging. Users can click to switch the selection box below the device icon from blank to displaying a "√", or switch the selection box below the device icon from displaying a "√" to blank, in order to select the target terminal device.

[0127] As shown in Figure 6c, after the user clicks the headphone icon 612, the display interface changes from Figure 6c to Figure 6d. Figure 6d shows a display interface that is essentially the same as the one shown in Figure 6c, except that the headphone icon 612 is selected in Figure 6d, while it is unselected in Figure 6c. That is, when the phone displays the interface shown in Figure 6d, it indicates that the target terminal devices include the phone itself and the headphones. The phone is the device shown in Figure 6, and the headphones can be headphones connected to the phone via Bluetooth.

[0128] In some embodiments, all devices in the target terminal device have the same charging speed and charging mode, namely the charging speed displayed by the slider 603 and the mode control displayed by the mode box 605 in the selected state, which are applicable to all devices in the target terminal device.

[0129] In other embodiments, the charging speed and charging mode of each device in the target terminal device are independent of other devices, that is, different devices can have different charging speeds and / or charging modes.

[0130] In some other embodiments, when the user clicks the switch control 601 in the interface shown in Figure 6a, the display interface can be switched to a different display interface than Figure 6b. For example, in the switched display interface, the three charging modes in the mode box 605 are all unselected, and / or the charging speed corresponding to the slider 603 in the switched interface is zero or other default values. This application will not elaborate on these points.

[0131] In some embodiments, in the interface shown in Figure 6b, when the user clicks the switch control 601, the display interface changes from the one shown in Figure 6b to the one shown in Figure 6a.

[0132] In some embodiments, when a user clicks on any area of ​​the interface displayed in Figure 6c, other than the floating frame 609, the displayed interface switches from the one shown in Figure 6c to the one shown in Figure 6b. Similarly, when a user clicks on any area of ​​the interface displayed in Figure 6d, other than the floating frame 609, the displayed interface switches from the one shown in Figure 6d to the one shown in Figure 6b.

[0133] Referring to Figure 7, this is a schematic diagram of the interface changes of a terminal device provided in an embodiment of this application. The display interface shown in Figure 7a is basically the same as the display interface shown in Figure 3a. The switch control 701 shown in Figure 7a is basically the same as the switch control 301 shown in Figure 3a. Therefore, the description of switch control 301 above can be referred to, and will not be repeated here. As shown in Figure 7a, after the user long-presses switch control 701, the display interface jumps from Figure 7a to Figure 7b.

[0134] The display interface shown in Figure 7b is similar to that shown in Figure 6c. This interface includes a background screen and a floating frame 709. The background screen displays a switch control 701, a speed control 702, and a mode box 705. The switch control 701 is in the selected state. The speed control 702 includes a slider 703 and two icons 704. The mode box 705 displays a "Health Mode" control 706, a "High-Speed ​​Mode" control 707, and a "Custom Mode" control 708. The floating frame 709 displays three device icons: a device icon 710, a watch icon 711, and a headphone icon 712, from left to right. All three icons are in the unselected state.

[0135] As shown in Figure 7b, the length of the shaded area in the speed control 702 is basically zero. All three mode controls in the mode box 705 are unselected. All three device icons displayed in the floating box 709 are unselected. Therefore, in the embodiment shown in Figure 7, when the switch control 701 is unselected, after long-pressing the switch control 701, all devices are unselected (or in other words, none of the devices are the target terminal devices), and the default charging speed is zero.

[0136] As shown in Figure 7b, after the user clicks the device icon 710, the display interface changes from Figure 7b to Figure 7c. Figure 7c shows a switch control 701, a speed control 702, and a mode box 705. The switch control 701 is in the selected state. The speed control 702 includes a slider 703 and two icons 704. The mode box 705 displays a "Health Mode" control 706, a "Speed ​​Mode" control 707, and a "Custom Mode" control 708.

[0137] As shown in Figure 7c, this display interface differs significantly from the interface shown in Figure 7b. The following mainly explains the differences; for other details not mentioned, please refer to the relevant description in Figure 7b.

[0138] In Figure 7c, the device icon 710 is selected, while in Figure 7b, the device icon 710 is not selected. When the phone displays the interface shown in Figure 7c, it means that the target terminal device only includes the device itself, which is the phone displaying the interface in Figure 7.

[0139] In Figure 7c, the "Health Mode" control 706 is selected, and the slider 703 displays the charging speed corresponding to the "Health Mode" control 706. The length of the shaded part of the slider 703 is not zero. In Figure 7b, the "Health Mode" control 706 is not selected, and the length of the shaded part of the slider 703 is zero.

[0140] As shown in Figure 7c, after the user clicks the headphone icon 712, the display interface changes from Figure 7c to Figure 7d. Figure 7d shows that this display interface is basically the same as the one shown in Figure 7c, except that the headphone icon 712 is selected in Figure 7d, while it is unselected in Figure 7c. That is, when the terminal device displays the interface shown in Figure 7d, it indicates that the target terminal device includes: the device itself and the headphones. The device itself is the mobile phone displaying the interface in Figure 7, and the headphones can be headphones connected to the mobile phone via Bluetooth.

[0141] In some embodiments, all devices in the target terminal device have the same charging speed and charging mode, namely the charging speed displayed by the slider 703 and the mode control displayed by the mode box 705 in the selected state, which are applicable to all devices in the target terminal device.

[0142] In other embodiments, the charging speed and charging mode of each device in the target terminal device are independent of other devices, that is, different devices may have the same or different charging speeds and / or the same or different charging modes.

[0143] In some other embodiments, when the user presses and holds the switch control 701 in the interface shown in Figure 7a, the display interface can be switched to a different interface than Figure 7b. For example, one or more of the three charging modes in the mode box 705 in the switched display interface are selected, one of the three device icons in the switched display interface is selected, and / or the charging speed corresponding to the slider 703 in the switched display interface is a non-zero default value. This application will not elaborate on these aspects.

[0144] In some embodiments, when a user clicks on any area of ​​the interface displayed in Figure 7b, Figure 7c, or Figure 7d, other than the floating box 709, the display interface jumps to the one shown in Figure 7a.

[0145] Referring to Figure 8, a schematic diagram of interface changes of a terminal device provided in an embodiment of this application is shown. The display interface shown in Figure 8a is basically the same as the display interface shown in Figure 3a. A switch control 801 is displayed in this interface. After the user clicks the switch control 801, the display interface jumps from the one shown in Figure 8a to the one shown in Figure 8b. The switch control 801 shown in Figure 8a is basically the same as the switch control 301 shown in Figure 3a. Therefore, the description of the switch control 301 in Figure 3a can be referred to above, and will not be repeated here.

[0146] As shown in Figure 8b, the display interface in Figure 8b is similar to that in Figure 5b. This interface displays a switch control 801, a speed control 802, and a mode box 805. The switch control 801 is in the selected state. The speed control 802 includes a slider 803 and two icons 804. The mode box 805 displays a "Health Mode" control 806, a "Speed ​​Mode" control 807, and a "Custom Mode" control 808. The switch control 801 shown in Figure 8b is basically the same as the switch control 501 shown in Figure 5b; therefore, the description of the switch control 501 in Figure 5b can be referred to earlier, and will not be repeated here.

[0147] As shown in Figure 8b, the display interface also includes a device display box 809, which displays three device icons: device icon 810, watch icon 811, and headphone icon 812, from left to right. Device icon 810 is selected, while watch icon 811 and headphone icon 812 are not selected. When a device icon is selected, it indicates that the corresponding device is a target terminal device capable of wireless charging; when a device icon is not selected, it indicates that the corresponding device cannot perform wireless charging, i.e., it is not a target terminal device. Users can click on the device icons to switch between selected and unselected states, or vice versa, to select and switch target terminal devices.

[0148] As shown in Figure 8b, in the display interface, the "Health Mode" control 806 in the mode box 805 is selected, while the "High-Speed ​​Mode" control 807 and the "Custom Mode" control 808 are not selected; in the device display box 809, the local device icon 810 is selected, while the watch icon 811 and the headphone icon 812 are not selected. That is, in the embodiment shown in Figure 8, after the user clicks the switch control 801 in the display interface shown in Figure 8a, the default target terminal device is the local device, and the default charging mode is "Health Mode," meaning that the charging speed corresponding to the "Health Mode" control 806 is used by default to charge the local device. As shown in Figure 8b, after the user clicks the watch icon 811 in this display interface, the display interface switches from the one shown in Figure 8b to the one shown in Figure 8c.

[0149] As shown in Figure 8c, the display interface includes a switch control 801, a speed control 802, a mode box 805, and a device display box 809. The switch control 801 is in the selected state. The speed control 802 includes a slider 803 and two icons 804. The mode box 805 displays a "Health Mode" control 806, a "Speed ​​Mode" control 807, and a "Custom Mode" control 808. The device display box 809 displays a device icon 810, a watch icon 811, and a headphone icon 812. Therefore, the display interface shown in Figure 8c is basically the same as the interface shown in Figure 8b. The difference between the display interface shown in Figure 8c and the display interface shown in Figure 8b lies in the different selected mode controls in mode box 805 and the different selected device icons in device display box 809.

[0150] In some embodiments, the device display frame 809 may also include an icon 813. If the user clicks the icon 813, the display interface will jump from Figure 8c to the wireless charging settings interface, where the user can configure various wireless charging settings. The specific content displayed on the wireless charging settings interface will be described in detail in subsequent embodiments and will not be specifically described here.

[0151] As shown in Figure 8c, both the device icon 810 and the watch icon 811 are selected in this display interface. Therefore, when the terminal device displays the interface shown in Figure 8c, it indicates that the target terminal device includes both the device and the watch corresponding to watch icon 811. It is understood that the watch is connected to the device for communication; for example, the device and watch can connect via Bluetooth, or they can connect to the same Wi-Fi network. The device and watch can also communicate through any other possible means, and this application does not impose any restrictions on this.

[0152] As shown in Figure 8c, in this display interface, the "Fast Mode" control 807 is selected, while the "Health Mode" control 806 and the "Custom Mode" control 808 are not selected. This display interface is shown after the user clicks the watch icon 811 in Figure 8b. This embodiment uses the charging speed corresponding to the "Fast Mode" control 807 to charge the watch. Therefore, in the embodiment shown in Figure 8, different devices in the target terminal device can use different charging speeds or charging modes for charging.

[0153] As shown in Figure 8c, when the user long-presses the headphone icon 812, the display interface changes from Figure 8c to Figure 8d. Figure 8d shows the wireless charging settings interface for the Bluetooth headphones. The specific content of the wireless charging interface will be described in detail below and will not be elaborated upon here.

[0154] It should be understood that in the embodiments shown in Figures 3 to 8, the user begins performing wireless charging-related operations from the control center interface of the mobile phone; these operations can be used to: enable wireless charging, disable wireless charging, or set wireless charging parameters, etc. Of course, the user can also begin performing wireless charging-related operations from the settings interface. The following is an exemplary description in conjunction with the accompanying drawings.

[0155] Referring to Figure 9, a schematic diagram of interface changes of a terminal device provided in an embodiment of this application is shown. Figure 9a shows the settings interface of a mobile phone. Users can access the display interface shown in Figure 9a by clicking the phone's settings icon (the interface containing the settings icon is not shown in Figure 9). The settings interface shown in Figure 9a displays a search box and multiple settings items. As shown in Figure 9a, among the multiple settings items is a setting item 901 named "Wireless Charging," which includes a setting item icon 902 and an expand control 903.

[0156] As shown in Figure 9a, when the user clicks to expand control 903, the displayed interface changes from Figure 9a to Figure 9b. Figure 9b shows the wireless charging settings interface.

[0157] It is understandable that when a user clicks icon 813 in the display interface shown in Figure 8c, they can jump to the wireless charging settings interface shown in Figure 9b. This application will not elaborate on this.

[0158] As shown in Figure 9b, the display interface includes a switch control 904, setting items 905 and 906, and a data usage notification 907. Specifically: switch control 904 is used to turn the wireless charging function on and off; setting item 905 is used to configure the charging network; setting item 906 is used to configure the charging mode; and data usage notification 907 displays the charging data usage. As shown in Figure 9b, setting item 905 includes the prompt "Network Selection" and an expand control 908; setting item 906 includes the prompt "Charging Mode Settings" and an expand control 909.

[0159] For example, the data usage notification 907 may include the charging data used, which may include: the charging data used by the device itself, or the charging data used by the device controlled by the device for wireless charging; the data usage notification 907 may also include the remaining charging data.

[0160] It is understood that the data usage notification information 907 may include charging data usage information for the current billing cycle, such as the charging data usage used in the current month and the remaining charging data usage in the current month; the data usage notification information 907 may also include cumulative data within a preset time period, and this application does not impose any restrictions on this.

[0161] As shown in Figure 9b, clicking the switch control 904 redirects to the interface shown in Figure 9c. Figure 9c also displays the switch control 904, settings 905 and 906, and a data usage warning message 907. The state of the switch control 904 in Figure 9c differs from that in Figure 9b. In Figure 9c, the switch control 904 is in the "on" state, indicating that the device's wireless charging function is enabled, meaning the device can control itself and other devices to wirelessly charge. In Figure 9b, the switch control 904 is in the "off" state, indicating that the device's wireless charging function is disabled, meaning the device cannot control itself or other devices to wirelessly charge. Settings 905, 906, and the data usage warning message 907 can be referred to in the description of Figure 9b, and will not be repeated here.

[0162] In some other embodiments, the switch control 904 in Figure 9c is in the ON state, in which the wireless charging function of the device and other devices is ON; the switch control 904 in Figure 9b is in the OFF state, in which the wireless charging function of the device and other devices is OFF. In this embodiment, as shown in Figure 9c, the wireless charging function of the device, Bluetooth headset, and smartwatch are all ON, which will not be described in detail here.

[0163] As shown in Figure 9c, the display interface also shows a charging device frame 910. The charging device frame 910 displays settings items corresponding to devices capable of wireless charging. Each setting item corresponds to one device. In this embodiment, the charging device frame 910 displays three setting items. Taking the setting item 911 corresponding to the Bluetooth headset as an example, this setting item 911 includes device identification information 9111 and an expansion control 9112. The device identification information 9111 includes the device name and device icon. Of course, the device identification information 9111 can also include the device name or device icon; this application does not impose any limitations on this. As shown in Figure 9c, when the user clicks the expansion control 9112, the display interface switches from the one shown in Figure 9c to the one shown in Figure 9d.

[0164] As shown in Figure 9d, this display interface is the wireless charging settings interface for Bluetooth headsets. The display interface in Figure 9d is the same as that in Figure 8d.

[0165] As shown in Figure 9d, the display interface shows a first switch control 912, a prompt 913, and a mode setting box 914. The first switch control 912 is used to turn the wireless charging switch of the Bluetooth headset on or off, or in other words, to turn the wireless charging switch function of the Bluetooth headset on or off.

[0166] For example, the prompt 913 is used to indicate the function of the first switch control 912. In this embodiment, the content of the prompt 913 is "Do you allow the device to perform wireless charging?" The content of the prompt 913 can also be any other similar content, which will not be elaborated here.

[0167] As shown in Figure 9d, the mode setting box 914 includes three power mode switch controls: a second switch control 915 corresponding to "Health Mode", a third switch control 916 corresponding to "Extreme Speed ​​Mode", and a fourth switch control 917 corresponding to "Custom Mode".

[0168] As shown in Figure 9d, the display interface also shows a speed control 918, which is used to adjust the charging speed of the Bluetooth headset. Speed ​​control 918 is basically the same as speed control 302 shown in Figure 3b. For details on speed control 918, please refer to the introduction of speed control 302; it will not be repeated here.

[0169] As shown in Figure 9d, the display interface also includes a display box 919, which displays the network that can be used for charging. For example, the names of the network operators can be displayed, such as "Operator 1" and "Operator 2".

[0170] In the display interface shown in Figure 9d, the wireless charging switch of the Bluetooth headset is in the off state. In this state, the second switch control 915, the third switch control 916, and the fourth switch control 917 in the mode setting box 914, the speed control 918, and the network control in the display box 919 are all inoperable. As shown in Figure 9d, after the user clicks the first switch control 912, the display interface jumps to the state shown in Figure 9e.

[0171] As shown in Figure 9e, this display interface is basically the same as the display interface shown in Figure 9d, the only difference being the display state of each control. As shown in Figure 9e, this display interface shows a first switch control 912, a prompt 913, and a mode setting box 914. The state of the first switch control 912 in Figure 9e is different from the state of the first switch control 912 in Figure 9d. In Figure 9e, the first switch control 912 is in the "on" state, which means the wireless charging function of the Bluetooth headset is enabled.

[0172] Furthermore, in the display interface shown in Figure 9e, the second switch control 915, the third switch control 916, and the fourth switch control 917 in the mode setting box 914 are all operable. It can be understood that at most one of these switches can be in the "on" state, meaning each device can only correspond to one charging mode.

[0173] As shown in Figure 9e, the speed control 918 in this display interface is in an operable state.

[0174] As shown in Figure 9e, the display interface displays available networks for charging in display box 919. In Figure 9e, the Bluetooth headset is currently using operator 1's network for wireless charging. Users can select the operator for wireless charging of the Bluetooth headset in display box 919. For example, clicking on operator 2 will switch to using operator 2's network for wireless charging.

[0175] For example, in addition to displaying the operator's name, display box 919 can also display the operator's charging data usage, such as the remaining charging data for the month and the charging data used for the month.

[0176] As shown in Figure 9e, after the user clicks the third switch control 916, the display interface jumps to Figure 9f. As shown in Figure 9f, the difference between this display interface and Figure 9e is that the speed control 918 and the third switch control 916 have different display states. The third switch control 916 is in the "on" state, while the speed control 918 displays the maximum charging speed. That is, in this display state, the Bluetooth headset uses "high-speed mode" for wireless charging.

[0177] Referring to Figure 10, which is a schematic diagram of the interface changes of a terminal device provided in an embodiment of this application. The display interface shown in Figure 10a is the same as the display interface shown in Figure 9b, both of which are wireless charging settings interfaces. For a detailed description of Figure 10a, please refer to the relevant content in Figure 9b, which will not be repeated here.

[0178] As shown in Figure 10a, when the user clicks to expand control 908, the display interface jumps to Figure 10b. Figure 10b shows the on / off switches for available networks and charging data usage information, as well as the network operator's name. Figure 10b displays two networks named "Operator 1" and "Operator 2," with both switches 1001 ("Operator 1") and 1002 ("Operator 2") in the off state. In this state, neither "Operator 1" nor "Operator 2" can be used for wireless charging.

[0179] Referring to Figure 11, a schematic diagram of interface changes of a terminal device provided in an embodiment of this application is shown. The display interface shown in Figure 11a is the same as the display interface shown in Figure 9b, both of which are wireless charging settings interfaces. For a detailed description of Figure 11a, please refer to the relevant content in Figure 9b, which will not be repeated here.

[0180] As shown in Figure 11a, when the user clicks to expand control 909, the display interface jumps to Figure 11b. Figure 11b shows three different charging modes and adjustment controls for each mode. Each control includes an increase button, a decrease button, and a charging speed value. The user can adjust the charging speed for each mode by clicking the increase and decrease buttons. The charging speed value represents the charging speed corresponding to that mode. For details regarding the charging controls, please refer to the description in Figure 5e; it will not be repeated here.

[0181] As shown in Figure 11b, the charging speed of "Health Mode" is 50%, the charging speed of "Extreme Speed ​​Mode" is 50%, and the charging speed of "Custom Mode" is 75%. It is understood that in this embodiment, the charging speed is expressed as a percentage of the maximum charging speed, i.e., the charging speed of "Health Mode" is 50% of the maximum charging speed. Of course, the absolute value of the charging speed can also be used, but this application does not enumerate these options.

[0182] As shown in Figure 11b, the display interface may also include control 1101. Users can add new charging modes by clicking control 1101. This application will not elaborate on this.

[0183] For example, the charging speed of "Health Mode" and "Extreme Speed ​​Mode" can only be adjusted within a certain speed range, thus ensuring the balance between "Health Mode" and "Extreme Speed ​​Mode".

[0184] It should also be understood that in this embodiment, the charging speed corresponding to each charging mode is a numerical value. The charging speed corresponding to the charging mode can also be set in other ways, such as setting each charging mode to correspond to a speed range. This application will not elaborate on this.

[0185] It should be understood that the number and names of the charging modes in Figure 12 are merely examples and are not intended to limit the specific charging modes and their number. Those skilled in the art can increase or decrease the number and names of the charging modes as needed, and this application does not enumerate them.

[0186] It should be understood that in the various embodiments of this application, the interfaces displayed by the various example terminal devices or mobile phones, and the various user operations, are merely illustrative and do not constitute a specific limitation on the embodiments of this application. For example, in some other embodiments of this application, the icons on the interfaces displayed by the various terminal devices provided above may include more or fewer icons than those displayed on any of the interfaces shown in the above figures, or some icons may be combined, or some icons may be split, or different icons, etc. The embodiments of this application do not impose any limitations here.

[0187] It should be understood that the above examples of application scenarios are merely illustrative and should not be construed as limiting the wireless charging method in the embodiments of this application.

[0188] For ease of understanding, the wireless charging method will be illustrated below from the perspectives of interaction between the first terminal device and the network device, and the interaction between the first terminal device, the target terminal device, and the network device.

[0189] Figure 12 is an interactive diagram of a wireless charging method provided in an embodiment of this application. The method may include steps S1210 to S1230, which are described in detail below.

[0190] S1210, the first terminal device receives the first information.

[0191] The first piece of information is used to instruct the target terminal device to be wirelessly charged.

[0192] It should be understood that the first terminal device is a terminal device that can interact with the user and can communicate with network devices. In the embodiments shown in Figures 3 to 11, the first terminal device is a mobile phone. Of course, the first terminal device can also be any other device that can interact with people and communicate with network devices, such as tablet computers, laptops, smart TVs, in-vehicle systems, wearable devices, etc. This application does not limit the specific type of the first terminal device.

[0193] It is understandable that the first information can be understood as the instruction information sent by the user to the first terminal device, or the interaction information between the user and the first terminal device. This instruction information or interaction information indicates to the first terminal device that the target terminal device needs to be wirelessly charged, so the first terminal device needs to instruct the network device to start wirelessly charging the target terminal device.

[0194] For example, a user can operate a first terminal device to enable the first terminal device to receive first information, that is, the first information can be information generated by the user's operation on the first terminal device.

[0195] For example, the first information may include: information generated by the user's first operation on the switch control displayed on the first terminal device. In this implementation, before step S1210, the wireless charging method further includes: the first terminal device displaying the switch control; and step S1210 may also be described as: the first terminal device receiving the user's first operation on the switch control.

[0196] It should be understood that the switch control is used to turn the wireless charging function of the target terminal device on or off.

[0197] For example, the switch controls can be displayed in the control center of the first terminal device. As shown in the embodiments of Figures 3 and 8, the switch controls are all set in the control center of the mobile phone, such as switch control 301, switch control 401, switch control 501, switch control 601, switch control 701, and switch control 801. The first operation can be the user clicking on switch control 301, switch control 401, switch control 501, switch control 601, switch control 701, or switch control 801.

[0198] In some embodiments, the switch control can also be displayed in the wireless charging setting interface of the first terminal device. The wireless charging setting interface can be accessed through the setting interface, specifically as shown in Figure 9b, where the switch control 904 is displayed. That is, the switch control 904 is the control that enables the wireless charging function to be turned on and off.

[0199] Understandably, the switch control can also be set in other applications or functional modules in the first terminal device. Users can bring up the interface displaying the switch control by opening other applications or functional modules, thereby realizing the on and off control of the wireless charging function in the target terminal device.

[0200] In some embodiments, the process of the first terminal device displaying the switch control specifically includes: the first terminal device receiving a user's selection operation on a first icon; the first terminal device displaying a wireless charging setting control in response to the user's selection operation on the first icon; the first terminal device receiving the user's operation on the wireless charging setting control; and the first terminal device displaying a wireless charging setting interface, which includes the switch control, in response to the user's selection operation on the wireless charging setting control. In this embodiment, the first terminal device displays the wireless charging control by the user selecting the first icon, and then displays the wireless charging setting interface. The switch control is set in the wireless charging setting interface, and the operation conforms to the user's usage habits, improving the user experience.

[0201] For example, in the embodiment shown in Figure 9, the first icon refers to the phone's settings icon (not shown in the figure), the wireless charging settings control refers to the settings item 901 shown in Figure 9a, the wireless charging settings interface refers to the display interface shown in Figure 9b, and the switch control includes a switch control 904. The first operation can be the user clicking the switch control 904.

[0202] In some embodiments, the target terminal device includes a second terminal device, and the process of the first terminal device displaying a switch control specifically includes: receiving a user's selection operation on a first icon; displaying a wireless charging setting control in response to the user's selection operation on the first icon; receiving a user's operation on the wireless charging setting control; displaying a wireless charging setting interface in response to the user's operation on the wireless charging setting control, the charging setting interface including at least one device icon, at least one device icon including the icon of the second terminal device; receiving a user's selection operation on the icon of the second terminal device; and displaying the charging setting interface of the second terminal device in response to the user's selection operation on the icon of the second terminal device, wherein a switch control corresponding to the second terminal device is displayed in the charging setting interface of the second terminal device. In the embodiment shown in FIG9, the first icon refers to the settings icon of the mobile phone (not shown in the figure), the wireless charging setting control may include the setting item 901 and the switch control 904 shown in FIG9a, and the wireless charging setting interface refers to the display interface shown in FIG9c. The user's selection of the icon of the second terminal device may include the user's click operation on the expand control 9112. The charging setting interface of the second terminal device includes the display interface shown in Figure 9d. The switch control corresponding to the second terminal device includes the first switch control 912.

[0203] In some embodiments, the charging setting interface of the second terminal device further includes a parameter control corresponding to the second terminal device. The method further includes: receiving a fourth operation from the user on the parameter control corresponding to the second terminal device; and determining the wireless charging parameters of the second terminal device based on the fourth operation. In the embodiment shown in FIG9, the charging setting interface of the second terminal device includes the display interface shown in FIG9 d, the display interface shown in FIG9 e, and the display interface shown in FIG9 f. The fourth operation includes: clicking the third switch control 916.

[0204] For example, the wireless charging parameters of the second terminal device may include at least one of the following: charging speed, charging mode, and charging network. Specific details regarding charging speed, charging mode, and charging network can be found in other sections and will not be repeated here.

[0205] It is understandable that the second terminal device is a device other than the first terminal device, and the second terminal device is a device that can communicate with the first terminal device.

[0206] In some embodiments, the method further includes: the first terminal device displaying charging billing information. For example, the charging billing information can be based on data usage, as shown in Figure e of Figure 9, which displays data usage information 907, and Figure b of Figure 10, which displays charging data usage information for different operator networks. Of course, any other feasible charging billing information can also be used to facilitate users obtaining timely information about wireless charging costs and improve user experience.

[0207] In some embodiments, the wireless charging settings interface further includes a parameter control, and the method further includes: a first terminal device receiving a third operation from a user on the parameter control; and the first terminal device determining the wireless charging parameters of the target terminal device based on the third operation.

[0208] For example, wireless charging parameters may include charging speed, charging mode, charging network, etc., and this application does not limit these parameters.

[0209] It is understood that the charging network is the network used for wireless charging. Different networks can be selected from different network operators, as shown in Figure 9e. In this embodiment, the network includes the network of operator 1 and the network of operator 2. In this embodiment, the wireless charging of the Bluetooth headset uses the network of operator 1.

[0210] For example, the display interface shown in Figure 9b is the wireless charging settings interface, where setting items 905 and 906 are parameter controls. The display interface shown in Figure 9c can also be called the wireless charging settings interface, where setting items 905 and 906 can both be regarded as parameter controls.

[0211] For example, the display interface shown in Figure 9e is the wireless charging setting interface for Bluetooth headsets. The display box 919, the second switch control 915, the third switch control 916, the fourth switch control 917, and the speed control 918 can all be regarded as parameter controls.

[0212] It should be understood that charging speed refers to the rate at which the wireless charging process proceeds. Charging speed can be expressed in terms of power; higher power results in faster charging speed, and lower power results in slower charging speed. Alternatively, charging speed can be expressed as a percentage of the maximum charging speed; a higher percentage of the maximum charging speed indicates a faster charging speed, and a lower percentage indicates a slower charging speed. For example, the third operation could be a user sliding or clicking on the speed control 918.

[0213] For example, the charging mode can correspond to a preset charging speed. That is, each charging mode can correspond to a preset charging speed. When the user selects a charging mode, the target terminal device is charged using the charging speed corresponding to that charging mode. In this case, the user does not need to select the charging speed again.

[0214] As shown in Figure 9e, the charging modes can include three types: "Health Mode", "Speed ​​Mode" and "Custom Mode".

[0215] It should also be understood that in this embodiment, the charging speed corresponding to each charging mode is a numerical value. The charging speed corresponding to each charging mode can also be set in other ways, such as setting each charging mode to correspond to a speed range, which will not be elaborated in this application. The name of the charging mode and the corresponding charging speed can be set as needed, which will not be elaborated in this application.

[0216] In some embodiments, the method further includes: a first terminal device determining wireless charging parameters of a target terminal device based on first information, wherein the wireless charging parameters include at least one of charging speed, charging mode, and charging network.

[0217] For example, in the embodiment shown in Figure 3, the first information received by the first terminal device also includes: information generated by the user's finger sliding operation on the speed control 302, and the first terminal device determines the magnitude of the charging speed based on the first information.

[0218] For example, in the embodiment shown in Figure 5, the first information received by the first terminal device also includes: information generated by the user clicking the "speed mode" control 507, and the first terminal device determines to use "speed mode" to wirelessly charge the target terminal device based on the first information.

[0219] For example, in the embodiment shown in Figure 10, when a user clicks switch control 1001 or switch control 1002 (not shown in the figure), the first information received by the first terminal device further includes: information generated by the user clicking switch control 1001 or information generated by the user clicking switch control 1002, and the first terminal device determines the network used for wireless charging based on the first information.

[0220] In some embodiments, the method further includes: the first terminal device activating the wireless charging function in the target terminal device based on the first information. For example, in the embodiment shown in FIG3, the first information received by the first terminal device is the information generated by the user clicking the switch control 301. The first terminal device activates the wireless charging function in the target terminal device based on the first information, and the interface shown in FIG3b shows that the wireless charging function in the target terminal device is in the on state.

[0221] For example, the first terminal device determines the wireless charging parameters of the target terminal device based on the first information, specifically including: the first terminal device responding to the first operation by displaying a parameter control; the first terminal device receiving a second operation from the user on the parameter control; and the first terminal device determining the wireless charging parameters of the target terminal device according to the second operation. In this embodiment, the user can control the wireless charging parameters through the second operation on the parameter control, improving the precision of the user's control over the wireless charging process. For example, in the embodiment shown in Figure 3, the user's operation of clicking the switch control 301 is the first operation, the parameter control is the speed control 302 shown in Figure 3b, the user's sliding operation on the speed control is the second operation, and the wireless charging parameter is the determined charging speed.

[0222] S1220, the first terminal device sends the second information to the network device based on the first information.

[0223] The second piece of information is used to instruct the network device to send a charging signal to the target terminal device, and the charging signal is used to wirelessly charge the target terminal device.

[0224] For example, the second information may include an instruction sent by the first terminal device to the network device to wirelessly charge the target terminal device.

[0225] In some embodiments, the second information may include attribute information of the target terminal device, which may include location information of the target terminal device. The first terminal device sends the location information of the target terminal device to the network device, so that the network device sends a charging signal based on the location information, thereby realizing wireless charging of the target terminal device.

[0226] It should be understood that the target terminal device is the device that the user wants to wirelessly charge, and the target terminal device may include one or more devices. For example, the target terminal device may include a first terminal device, a target terminal device may include a terminal device connected to the first terminal device, or the target terminal device may include both the first terminal device and a terminal device connected to the first terminal device.

[0227] For example, prior to step S1230, the method further includes: the first terminal device determining the target terminal device based on the first information.

[0228] In some embodiments, the first terminal device determines the target terminal device based on first information, specifically including: the first terminal device determining the target terminal device in response to a user's first operation on a switch control displayed on the first terminal device. That is, the first terminal device can confirm the target terminal device requiring wireless charging simply by the user's first operation on the switch control, making the operation simple and easy to implement. In the embodiment shown in Figure 3, the first operation is the user clicking the switch control 301. In the embodiment shown in Figure 3, the target terminal device may include the first terminal device (i.e., the local device) or a device connected to the first terminal device. Of course, the target terminal device may include both the first terminal device and a device connected to the first terminal device.

[0229] In other embodiments, the first terminal device determines the target terminal device based on first information, specifically including: the first terminal device, in response to a user's first operation on a switch control displayed on the first terminal device, displays at least one device icon, the at least one device icon including the icon of the first terminal device and the icon of a terminal device connected to the first terminal device; the first terminal device receives a user's first selection operation on the first device icon among the at least one device icons; and the first terminal device, in response to the first selection operation, determines the terminal device corresponding to the first device icon as the target terminal device. In this embodiment, the first terminal device displays a selectable device icon in response to the first operation, making it easier for the user to select the target terminal device from multiple devices and improving the efficiency of the user in determining the target terminal device.

[0230] For example, in the embodiment shown in Figure 7, the user's operation of long-pressing the switch control 701 shown in Figure 7a is the first operation. The device icon 710, watch icon 711, and headphone icon 712 shown in Figure 7b are device icons. The user's operation of clicking the device icon 710 shown in Figure 7b, and the user's operation of clicking the headphone icon 712 in the interface shown in Figure 7c, can both be regarded as the first selection operation.

[0231] In other embodiments, the target terminal device includes multiple terminal devices. Some of these terminal devices are directly determined by the first terminal device in response to the first operation, while others require further user operation to determine. In the embodiment shown in Figure 6, the first operation is clicking the switch control 601 in the display interface shown in Figure 6a. This operation determines the target terminal device, meaning that the switch control 601 is turned on by default and needs to wirelessly charge the device. The user then long-presses the switch control 601 in the display interface shown in Figure 6b and clicks the headphone icon 612 in the display interface shown in Figure 6c. The first terminal device then identifies the Bluetooth headset as the target terminal device.

[0232] Understandably, the first terminal device needs to determine the wireless charging parameters of the target terminal device before sending the second information to the network device. The second information may include the wireless charging parameters, or it may include information used to determine the corresponding wireless charging parameters.

[0233] For example, the first terminal device can determine the power of the charging signal required to reach the charging speed based on the charging speed. Therefore, the second information can include the power of the charging signal, and the network device can determine the power of the charging signal to be transmitted to the target device based on the second information. Alternatively, the second information can include the charging speed, and the network device can determine the power of the charging signal to be transmitted to the target device based on the charging speed in the second information.

[0234] S1230, the network device sends a charging signal to the target terminal device based on the second information.

[0235] It is understandable that after receiving the second information, the network device determines the charging signal corresponding to the second information according to the instructions of the second information, and sends the charging signal to the target terminal device.

[0236] In this embodiment, users can manage the wireless charging process of the target terminal device by performing simple operations on the first terminal device. This allows users to control the wireless charging of the target terminal device from the first terminal device, facilitating user management of the wireless charging of the target terminal device and improving user experience.

[0237] In some embodiments, the first information includes information generated by a user selecting a target terminal device from multiple devices. The second information may then include the identification information of each target terminal device, and may also include the power of the charging signal corresponding to each target terminal device. In the second information, there may be a set of information for each target terminal device, or the information in the second information may be sorted according to information type and the target terminal device to which it belongs.

[0238] In some embodiments, the first information includes information generated by the user's selection of a charging mode, and the second information may include information corresponding to the charging mode selected by the user (e.g., the power of the charging signal, the time-frequency resources of the charging signal, etc.). The information corresponding to the charging mode may be predefined.

[0239] For example, the predefined power of the charging signal in "Health Mode" is P1, and the time-frequency resources are time-domain unit X and frequency-domain unit Y. When the first information indicates that the user has selected "Health Mode" for the target terminal device, the power of the charging signal in the second information is P1, and the time-frequency resources of the charging signal are time-domain unit X and frequency-domain unit Y. The network device can send the charging signal to the target terminal device with power P1 in time-domain unit X and frequency-domain unit Y.

[0240] In some other embodiments, the second information may include: information that the first terminal device sent to the network device when the target terminal device was first or last charged by the network device.

[0241] For example, the first terminal device is a mobile phone, and the target terminal device includes headphones. When the headphones were first or last charged via the network device, the user selected a charging speed of V1 for the headphones on the first terminal device, and the power of the charging signal corresponding to this charging speed was P2. The first information is generated when the user identifies the headphones as the target terminal device on the mobile phone, but the user did not select or perform any operation on the charging mode or charging speed. The second information sent by the mobile phone to the network device includes the charging power being P2, meaning the network device sends a charging signal with a power of P2 to the headphones.

[0242] In some embodiments, the second information includes at least one of the following: the identifier of the first terminal device, the identifier of the target terminal device, the power of the charging signal, the timing information of the charging signal, the time-frequency resources of the charging signal, and the location information of the target terminal device.

[0243] Understandably, the identifiers of the first terminal device and the target terminal device are used to identify the target terminal device that needs wireless charging; the power of the charging signal is used to determine the charging speed, and the greater the power of the charging signal, the greater the charging speed; the time information of the charging signal determines the time domain information of the charging signal; and the reasonable allocation, management and optimization of the time and frequency resources of the charging signal can improve the spectrum efficiency and rate of wireless charging.

[0244] It should be understood that the beamwidth of the charging signal can be determined based on the location information of the target terminal device. By reasonably setting the beamwidth of the charging signal, multiple devices can be wirelessly charged using a single beam, thereby improving the utilization rate of the charging signal. For example, if the target terminal device includes multiple devices, for two devices whose distance is less than a preset threshold, the same beam can be used for wireless charging. The first terminal device can calculate the beamwidth of the charging signal based on the distance between the two devices, so that the beamwidth of the charging signal can cover both devices.

[0245] It is understandable that each device in the target terminal can correspond to a separate set of second information; or the second information can also include information corresponding to all target terminal devices, in which the information corresponding to all target terminal devices can be sorted according to information type and device.

[0246] To facilitate understanding, the second piece of information will be described in more detail below.

[0247] In some embodiments, the second information may include: the identifier of the first terminal device, which the network device uses to wirelessly charge the first terminal device.

[0248] In some embodiments, the second information may include: the identifier of the target terminal device, and the network device wirelessly charges the target terminal device based on the identifier of the target terminal device.

[0249] In some embodiments, the second information may include the power of the charging signal. The charging signal power in the second information sent by the first terminal device to the network device is the charging signal power that the target terminal device expects to obtain.

[0250] Assuming the charging signal power is a first power, after receiving the second information: if the network device determines that it can provide a charging signal with the first power, then the network device sends a charging signal to the target terminal device according to the first power; if the network device determines that it cannot provide a charging signal with the first power, then the network device can send a charging signal to the target terminal device according to the second power it can provide, where the second power is less than the first power.

[0251] Understandably, when the network device sends a charging signal to the target terminal device at the second power, if the DC voltage converted from the charging signal at the second power is greater than or equal to the turn-on voltage of the rectifier circuit, the target terminal device can store energy to achieve wireless charging; if the DC voltage converted from the charging signal at the second power is less than the turn-on voltage of the rectifier circuit, the target terminal device cannot achieve wireless charging.

[0252] For example, if the target terminal device includes a first terminal device, and the first terminal device determines that wireless charging has not been achieved within a preset time after the user activates the charging control, then the first terminal device displays a prompt message indicating that charging is not possible; if the target terminal device includes other terminal devices connected to the first terminal device, and the other terminal devices have not achieved wireless charging within a preset time, then the other terminal devices report to the first terminal device that wireless charging is not possible.

[0253] In some embodiments, the second information may include: timing information of the charging signal. The timing information of the charging signal in the second information sent by the first terminal device to the network device is the time-domain resource information that the target terminal device expects to obtain the charging signal.

[0254] For example, the timing information of the charging signal may include a charging start time domain unit and a charging end time domain unit; after receiving the charging start time domain unit and the charging end time domain unit, the network device may send a charging signal to the target terminal device according to the charging start time domain unit, and stop sending the charging signal to the target terminal device at the charging end time domain unit.

[0255] For example, the timing information of the charging signal may include: a charging start time domain unit and a time domain unit carrying the charging signal; after receiving the charging start time domain unit and the time domain unit carrying the charging signal, the network device may send the charging signal to the target terminal device according to the charging start time domain unit, and stop sending the charging signal to the target terminal device after reaching the time domain unit carrying the charging signal.

[0256] For example, the timing information of the charging signal may include: a time-domain unit carrying the charging signal; after the network device receives the time-domain unit carrying the charging signal, the time-domain unit carrying the charging signal starts sending the charging signal to the target terminal device, and stops sending the charging signal to the target terminal device after reaching the time-domain unit carrying the charging signal.

[0257] Of course, if the network device cannot send a charging signal according to the time information of the wireless charging signal after receiving the charging signal time information, it can send the charging signal time information to the first terminal device and send the charging signal to the target terminal device after receiving the feedback from the first terminal device.

[0258] In some embodiments, the second information may include: time-frequency resources of the charging signal. The time-frequency resources of the charging signal in the second information sent by the first terminal device to the network device are the time-domain and frequency-domain resources of the charging signal that the target terminal device expects to obtain.

[0259] For example, the time-frequency resources of a charging signal may include multiple combined information, each of which includes the time-domain unit and the frequency-domain unit where the charging signal is located. For example, the time-frequency resources of a charging signal may include: time-domain unit 1 and frequency-domain unit 1, time-domain unit 2 and frequency-domain unit 2, ..., time-domain unit N and frequency-domain unit N, where N is an integer greater than or equal to 1.

[0260] For example, after receiving the time-frequency resources for a charging signal, if the network device determines that such time-frequency resources are available, it can send a charging signal to the target terminal device according to the available time-frequency resources. For instance, if time-domain unit 2 and frequency-domain unit 2 in the network device are available, the network device can send a charging signal to the target terminal device using time-domain unit 2 and frequency-domain unit 2.

[0261] Optionally, before sending a charging signal to the target terminal device, the network device may send a seventh piece of information to the first terminal device. This seventh piece of information informs the first terminal device of the time-domain resource information of the charging signal to be sent by the network device to the target terminal device. This seventh piece of information includes an indication field, used to indicate whether the charging signal is sent according to the time-frequency position in the second information. For example, if the indication field is 1 bit or 0, it indicates that the time-frequency resources carrying the charging signal are included in the time-frequency resources provided in the second information. The network device can use a combination of time-domain and frequency-domain units in the seventh piece of information to indicate the time-domain resource position of the charging signal. For example, if the seventh piece of information occupies 4 bits and the indication field is in the first bit position, then 0110 indicates that the time-frequency resources carrying the charging signal are included in the time-frequency resources provided in the second information, and the time-frequency resources carrying the charging signal are time-domain unit 2 and frequency-domain unit 2. When the indication field indicates that the time-frequency resources for sending the charging signal are not included in the second information, for example, if the indication field is 1 bit or 1, then the seventh piece of information needs to indicate the specific time-frequency resource position.

[0262] For example, after receiving the time-frequency resources for a charging signal, if the network device determines that none of the aforementioned time-frequency resources are available, then the network device can select another available time-frequency resource to send a charging signal to the target terminal device.

[0263] In some other embodiments, the time-frequency resources of the charging signal sent by the first terminal device to the network device include: N time-domain units and M frequency-domain units, wherein the N time-domain units include time-domain unit 1 to time-domain unit N, and the M frequency-domain units include frequency-domain unit 1 to frequency-domain unit M, where N is an integer greater than or equal to 1, and M is an integer greater than or equal to 1.

[0264] For example, after receiving the time-frequency resources for a charging signal, the network device can select one idle time-domain unit from N time-domain units and one idle frequency-domain unit from M frequency-domain units, and send the charging signal to the target terminal device according to the selected time-domain unit and frequency-domain unit. For instance, if time-domain unit 2 and frequency-domain unit 5 in the network device are idle, then the network device will send the charging signal to the target terminal device in time-domain unit 2 and frequency-domain unit 5.

[0265] Optionally, before sending a charging signal to the target terminal device, the network device may send a seventh piece of information to the first terminal device. This seventh piece of information informs the first terminal device of the time-domain resource information of the charging signal to be sent by the network device to the target terminal device. This seventh piece of information includes an indication field to indicate whether the charging signal is sent according to the time-frequency position in the second information. For example, if the indication field is 1 bit, or if it is 0, it indicates that the time-frequency resources carrying the charging signal are included in the time-frequency resources provided in the second information. The network device may use the index of the time-domain unit and the index of the frequency-domain unit in the seventh piece of information to indicate the time-domain resource position of the charging signal. For example, the seventh piece of information occupies 5 bits, with the indication field located in the first bit position, the second and third bits representing the time-domain resource index carrying the charging signal, and the fourth and fifth bits representing the frequency-domain resource index carrying the charging signal. For example, 01110 indicates that the time-frequency resources carrying the charging signal are included in the time-frequency resources provided in the second information, and the time-domain resources carrying the charging signal are time-domain unit 3 and frequency-domain unit 2. When the indication field indicates that the time-frequency resource for the network device to send a charging signal is not included in the second information, for example, if the indication field is 1 bit or the indication field is 1, then the seventh information needs to indicate the specific location of the time-frequency resource.

[0266] In some other embodiments, the second information does not include the time-frequency resources of the charging signal. In this case, the network device can send the charging signal to the target terminal device according to its own resource availability.

[0267] In some embodiments, the second information may include: location information of the target terminal device. The location information of the target terminal device sent by the first terminal device to the network device indicates the location that the target terminal device expects the charging signal to cover.

[0268] For example, the first terminal device is a mobile phone, and the target terminal devices include the mobile phone and earphones. The second information sent by the mobile phone to the network device includes the distance information between the mobile phone and the earphones. After receiving the distance information, the network device: if it determines that the mobile phone and earphones are close, the network device uses one beam to wirelessly charge the mobile phone and earphones, and the beam width is large enough to cover the mobile phone and earphones; if it determines that the mobile phone and earphones are far apart, the network device uses two beams to wirelessly charge the mobile phone and earphones. When the network device uses two beams, one beam covers the mobile phone and the other beam covers the earphones; it can be understood that the network device can use a time-division multiplexing method to transmit the two beams.

[0269] For example, the first terminal device is a mobile phone, and the target terminal devices include a mobile phone, earphones, and a watch. The second information sent by the mobile phone to the network device includes the distance between the mobile phone and the earphones, and the distance between the mobile phone and the watch. After receiving the distance information, the network device determines, based on the two distance values, whether to use one beam or multiple beams to wirelessly charge the three devices, and the width of the beams used.

[0270] For example, the first terminal device is a mobile phone, and the target terminal device includes the mobile phone and at least one other device. The second information sent by the mobile phone to the network device may include the location information of the mobile phone and the location information of each other device. The network device sends a beam of light to the mobile phone and each other device respectively based on the location information of the mobile phone and each other device.

[0271] It is understandable that network devices can determine the location of the first terminal device based on its identifier, therefore the second information may not include the location information of the first terminal device.

[0272] In some embodiments, the second information includes: the identifier of the target terminal device. After receiving the identifier of the target terminal device, the network device determines the location of the target terminal device based on the identifier of the target terminal device, and determines the beam used by the charging signal based on the location of the target terminal device.

[0273] For example, if the first terminal device is a mobile phone, and the target terminal devices include a mobile phone, earphones, and a watch, and the distance between these three devices is relatively short, then a wider beam can be used to cover them. If the distance between these three devices is relatively far, then the network device can send a narrower beam to each of them.

[0274] In some embodiments, the wireless charging method further includes: receiving fourth information, the fourth information being used to instruct the target terminal device to stop wirelessly charging; and based on the fourth information, sending fifth information to a network device, the fifth information being used to instruct the network device to stop sending charging signals to the target terminal device. It should be understood that the fourth information can be understood as instruction information sent by the user to the first terminal device, or information of interaction between the user and the first terminal device, and the fifth information may include an instruction sent by the first device to the network device to stop wirelessly charging the target terminal device.

[0275] For example, in the embodiment shown in Figure 3, if the user clicks the switch control 301 in the display interface shown in Figure b of Figure 3, the fourth information received by the first terminal device is the information generated by the user clicking the switch control 301, and the first terminal device turns off the wireless charging switch in the target terminal device.

[0276] In some other embodiments, when the second information includes the timing information of the charging signal, the network device can determine when to stop sending the charging signal to the target terminal device based on the second information, and the first terminal device does not need to send the fifth information to the network device after receiving the fourth information.

[0277] Figure 13 is an interactive diagram of a wireless charging method provided in an embodiment of this application. The target terminal device in this embodiment includes terminal devices other than the first terminal device, which can be devices connected to the first terminal device. For example, the first terminal device is a mobile phone, and the target terminal devices include Bluetooth headsets, smartwatches, etc., connected to the mobile phone. The method may include steps S1310 to S1340, which are described in detail below.

[0278] S1310, the first terminal device receives the first information.

[0279] For a detailed description of this step, please refer to step S1210 in Figure 12, which will not be repeated here.

[0280] S1320, the first terminal device sends the second information to the network device based on the first information.

[0281] For a detailed description of this step, please refer to step S1220 in Figure 12, which will not be repeated here.

[0282] S1330, the first terminal device sends third information to the target terminal device based on the first information.

[0283] It is understood that the third information may include the instruction sent by the first terminal device to the target terminal device to receive the charging signal.

[0284] In some embodiments, the first terminal device determines the target terminal device that needs to be wirelessly charged based on first information. For example, in the embodiment shown in FIG6, the first information received by the first terminal device includes the user clicking the switch control 601 and the user clicking the headphone icon 612. The first terminal device will then enable the wireless charging function of the headphones, and the headphones will be identified as the target terminal device.

[0285] S1340, the network device sends a charging signal to the target terminal device based on the second information.

[0286] For a detailed description of this step, please refer to step S1230 in Figure 12, which will not be repeated here.

[0287] S1350, the target terminal device receives a charging signal from the network device based on the third information.

[0288] In some embodiments, the third information may include an instruction sent by the first terminal device to the target terminal device to receive a charging signal.

[0289] In some other embodiments, the third information may not include instructions to receive charging signals, meaning that the target terminal device is always in a state where it can receive charging signals.

[0290] In some embodiments, before sending a charging signal to a target terminal device, the network device sends seventh information to a first terminal device. This seventh information includes information related to the charging signal the network device will send to the target terminal device, such as at least one of the following: the power of the charging signal, the timing information of the charging signal, and the time-frequency resources of the charging signal. After receiving the seventh information, the first terminal device sends it as third information to the target terminal device. In this case, the third information is the same as the seventh information and may include at least one of the following: the power of the charging signal, the timing information of the charging signal, and the time-frequency resources of the charging signal. In this embodiment, the target terminal device can obtain specific information about the charging signal based on the third information, thereby accurately obtaining the charging signal sent by the network device.

[0291] For a detailed description of the power, timing information, and time-frequency resources of the charging signal, please refer to the previous text, which will not be repeated here.

[0292] In some embodiments, the wireless charging method further includes: sending sixth information to a target terminal device based on fourth information, wherein the sixth information is used to instruct the target terminal device to stop receiving charging signals from the network device. It should be understood that the fourth information can be interpreted as instruction information sent by the user to the first terminal device, or information from the interaction between the user and the first terminal device, and the sixth information may include an instruction sent by the first device to the target terminal device to stop receiving charging signals.

[0293] In some other embodiments, when the third information includes the timing information of the charging signal, the target terminal device can determine when to stop receiving the charging signal based on the third information, and the first terminal device does not need to send the sixth information to the target terminal device after receiving the fourth information.

[0294] It should be understood that the above description is merely to help those skilled in the art better understand the embodiments of this application, and is not intended to limit the scope of the embodiments of this application.

[0299] This embodiment can divide various devices (including the aforementioned first terminal device (e.g., mobile phone), target terminal device (e.g., Bluetooth headset, smartwatch), and network device (e.g., base station)) into functional modules according to the above method. For example, each function can be divided into its own functional modules, or two or more functions can be integrated into one processing module.

[0303] For example, Figure 14 shows a schematic diagram of the hardware structure of a communication device 1400 provided in this application. The communication device 1400 can be a terminal device (e.g., a first terminal device, a target terminal device), such as a smartphone, tablet computer, or laptop computer. As shown in Figure 14, the communication device 1400 may include a processor 1410, an external memory interface 1420, an internal memory 1421, a universal serial bus (USB) interface 1430, a charging management module 1440, a power management module 1441, a battery 1442, an antenna 1, an antenna 2, a wireless communication module 1450, etc.

[0304] It is understood that the structure illustrated in the embodiments of this application does not constitute a specific limitation on the communication device 1400. In other embodiments of this application, the communication device 1400 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements.

The controller can generate operation control signals based on instruction opcodes and timing signals to control instruction fetching and execution.

[0307] In some embodiments, the processor 1410 may include one or more interfaces.

[0309] The wireless communication function of the communication device 1400 can be realized through antenna 1, antenna 2 and wireless communication module 1450, etc.

[0310] The wireless communication module 1450 can provide solutions for wireless communication applications on the communication device 1400, including Wi-Fi (including Wi-Fi sensing and Wi-Fi AP), Bluetooth (BT), and wireless data transmission modules (e.g., 433MHz, 868MHz, 15115MHz). The wireless communication module 1450 can be one or more devices integrating at least one communication processing module. The wireless communication module 1450 receives electromagnetic waves via antenna 1 or antenna 2 (or antenna 1 and antenna 2), filters and frequency-modulates the electromagnetic wave signals, and sends the processed signal to the processor 1410.

It can also be a chip or component applied to the first terminal device. Furthermore, each module or unit in the communication device 1500 is used to execute the various actions or processing procedures performed by the first terminal device (mobile phone) or target terminal device described in the various embodiments of the wireless charging method. As shown in Figure 15, the communication device 1500 may include a processing unit 1510 and a communication unit 1520. Optionally, the communication device 1500 may also include a storage unit 1530.
