[0055] Figure 13 This is a block diagram of an electronic device according to an exemplary embodiment. Detailed Implementation

[0056] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0057] Figure 1 This is a schematic diagram of an antenna tuning system according to an exemplary embodiment, such as... Figure 1 As shown, the antenna tuning system includes a protocol stack, a transceiver, a control module, and multiple antenna tuners. The protocol stack is connected to the physical layer, the physical layer is connected to the control module, and the control module is connected to the multiple antenna tuners. The protocol stack refers to the collection of software or hardware modules in a modem that implement various communication protocols.

[0058] The antenna tuning process is as follows: When the protocol stack detects the need to switch between different cell scenarios, it sends relevant instructions to the control module through the physical layer. Then, the control module performs calculations and controls the antenna tuner to complete the tuning of the antenna tuner.

[0059] In some embodiments, the antenna tuning system may also be called a multimode antenna tuning system, the protocol stack may also be called a Modem protocol stack, and the control module may also be called an antenna tuner control module.

[0060] In related technologies, antenna tuning systems need to switch rapidly between different frequency bands and communication modes to adapt to dynamically changing communication requirements. However, external independent control chips need to communicate and coordinate frequently with the main system during tuning, which may lead to delays and asynchrony in tuning operations, i.e., the tuning state cannot be switched in a timely manner when switching frequency bands. For example, while the protocol stack switches frequency bands, it tunes the antenna tuner through the transceiver scheduling control module in the physical layer. However, the control module requires a certain amount of processing time, resulting in asynchrony between the frequency band switching and the tuning state switching of the antenna tuner. This can cause signal interruption or signal jumps, which in turn affect subsequent network registration, calls, data transmission, and other services, resulting in a poor user experience.

[0061] The method provided in this disclosure is executed by an electronic device, which can be a mobile phone, tablet computer, laptop computer, smartwatch, smart home device, vehicle terminal, or other device equipped with an antenna. In addition, the electronic device also includes various hardware resources and energy storage devices that provide power for the operation of these hardware resources.

[0062] Figure 2 This is a flowchart illustrating an antenna tuning method according to an exemplary embodiment, performed by an electronic device, see [link to flowchart]. Figure 2 The method includes the following steps:

[0063] Step S201: In response to the frequency band switching request for the operating frequency band of the target antenna, the antenna tuner corresponding to the target antenna is tuned so that the tuned state of the antenna tuner after tuning matches the target frequency band; the frequency band switching request includes the target frequency band.

[0064] The frequency band switching request is used to request that the operating frequency band of the target antenna be switched to the target frequency band.

[0065] Based on the target frequency band, the antenna tuner corresponding to the target antenna is tuned accordingly to match the tuned state of the antenna tuner with the target frequency band. Matching the tuned state with the target frequency band means that the target antenna can achieve better operating performance in the target frequency band under this tuned state. The tuned state refers to the specific operating state of the antenna system achieved by the antenna tuner adjusting its own parameters. In other words, matching the tuned state of the antenna tuner with the target frequency band ensures adaptation between the tuned state and the target frequency band, thereby guaranteeing efficient signal transmission and reception.

[0066] In some embodiments, the antenna switching request can be triggered when the electronic device switches mobile networks, for example, when the electronic device switches from a 4G network to a 5G network, the antenna's operating frequency band needs to be switched to the target frequency band corresponding to 5G. Alternatively, the antenna switching request can also be triggered when the electronic device moves from a first environment to a second environment. For example, in a natural environment, there are fewer electronic devices, and the current electronic device is not easily interfered with. However, in an industrial production environment, there are various production devices, and these devices can interfere with specific frequency bands when they are working. Therefore, when the electronic device moves from a natural environment to an industrial production environment, the operating frequency band of the electronic device needs to be switched to another operating frequency band that is not interfered with by the production devices. Alternatively, the antenna switching request can also be issued by a network device. For example, in a satellite communication scenario, the network device determines the target frequency band required for the current satellite communication based on the current data transmission requirements and then issues an antenna switching request to the electronic device. Of course, antenna switching requests can also be triggered in other application scenarios, and this disclosure does not limit this.

[0067] In some embodiments, tuning the antenna tuner includes adjusting its own parameters, such as changing the capacitance and inductance. By tuning the antenna tuner, the input impedance of the target antenna can be matched with the characteristic impedance of the transmission line to achieve efficient signal transmission and maximized power transmission. In this case, when the antenna tuner adjusts the input impedance of the target antenna to be equal to the characteristic impedance of the transmission line, the tuning state is considered to be matched with the target frequency band.

[0068] Step S202: In response to completing the tuning of the antenna tuner, the operating frequency band of the target antenna is switched to the target frequency band.

[0069] After tuning the antenna tuner, its parameters are more suitable for the target frequency band. At this point, switching the target antenna to its operating frequency band can avoid signal interruption or signal jump during the frequency band switch.

[0070] The method provided in this disclosure first tunes the antenna tuner of the target antenna. In response to the completion of the tuning of the antenna tuner, the operating frequency band of the target antenna is switched to the target frequency band. This ensures that the target antenna performs frequency band switching after tuning is completed, thereby avoiding synchronization problems of the antenna tuner and signal interruption or signal jump when frequency band switching occurs, thus improving the user experience.

[0071] In some embodiments, in response to a frequency band switching request, a tuning command is generated, and in response to the tuning command, the antenna tuner is tuned to match the tuned state of the antenna tuner with a target frequency band. The tuning command instructs the antenna tuner to be tuned. Optionally, the tuning command may include a target frequency band to instruct the antenna tuner to be tuned to a tuning state matching the target frequency band.

[0072] In some embodiments, since the target antenna's operating frequency band needs to be switched to the target frequency band after the antenna tuner has been tuned, it is necessary to first determine whether the antenna tuner has been tuned.

[0073] Optionally, a first duration can be preset, which is the time required from generating the tuning command to completing the tuning of the antenna tuner. Then, after generating the tuning command, the elapsed duration is monitored and compared with the first duration to determine whether the tuning of the antenna tuner has been completed. Figures 3 to 7 The illustrated embodiments provide a detailed description of this.

[0074] Optionally, feedback can be provided after tuning the antenna tuner is completed. The result of the feedback can be used to determine whether tuning of the antenna tuner has been completed, through the following... Figures 8 to 10 The illustrated embodiments provide a detailed description of this.

[0075] Figure 3 This is a flowchart illustrating an antenna tuning method according to an exemplary embodiment, performed by an electronic device. See also... Figure 3 The method includes the following steps:

[0076] Step S301: In response to the frequency band switching request, a tuning command is generated.

[0077] In some embodiments, the protocol stack generates a tuning instruction in response to a frequency band switching instruction.

[0078] Optionally, the AP (Application Processor) or network device sends a frequency band switching request to the protocol stack, and the protocol stack receives the frequency band switching request.

[0079] Step S302: In response to the tuning command, the antenna tuner is tuned so that the tuned state of the antenna tuner matches the target frequency band.

[0080] In some embodiments, the protocol stack sends a tuning command to the control module; in response to the tuning command, the control module tunes the antenna tuner. The control module determines tuning parameters to tune the antenna tuner.

[0081] Optionally, the protocol stack sends tuning commands to the transceiver, and the transceiver then sends tuning commands to the control module.

[0082] Optionally, the protocol stack sends tuning commands to the transceiver; the transceiver processes the tuning commands, generates control commands, and sends the control commands to the control module; in response to the control commands, the control module tunes the antenna tuner. The control commands instruct the control module to tune the antenna tuner.

[0083] In some embodiments, in response to a tuning command, tuning parameters are determined; and the antenna tuner is tuned based on the tuning parameters. The tuning parameters may include parameters such as the capacitance, inductance, and resistance of the antenna tuner.

[0084] In some embodiments, a preset algorithm is used to calculate the tuning parameters. For example, the preset algorithm can be a formula related to LC (inductor-capacitor) network theory, a formula related to transmission line theory, etc. In this embodiment, the method of calculating the tuning parameters is not limited.

[0085] In some embodiments, tuning parameters matching the current scenario information are queried from stored tuning information. The tuning information includes tuning parameters corresponding to different scenario information. Scenario information characterizes the usage scenario of the electronic device, and the current scenario information characterizes the current usage scenario of the electronic device; for example, the current scenario information can be a 4G scenario, a 5G scenario, etc.

[0086] Optionally, the current scene information can be sent from the protocol stack to the control module. For example, the protocol stack sends tuning instructions and current scene information to the control module.

[0087] Optionally, the tuning information is stored in the control module. The tuning information can be stored in list form or other forms. This embodiment of the disclosure does not limit the storage form of the tuning information.

[0088] It should be noted that the above embodiments take the determination of tuning parameters in response to tuning commands as an example. In some embodiments, the tuning parameters can be determined in response to frequency band switching requests.

[0089] In step S303, in response to the timing duration reaching the first duration, the operating frequency band of the target antenna is switched to the target frequency band.

[0090] In some embodiments, in response to a timing period reaching a first duration, the protocol stack sends a frequency band switching command to the target antenna to switch the operating frequency band of the target antenna to the target frequency band. The frequency band switching command indicates the target frequency band after the target antenna has switched.

[0091] In some embodiments, if a preset algorithm is used to calculate the tuning parameters, it takes a long time, while if the pre-stored tuning parameters are directly queried, it takes less time. Therefore, corresponding first durations can be set for these two different situations, and the first duration for calculating the tuning parameters is longer than the first duration for querying the pre-stored tuning parameters.

[0092] Optionally, the first duration is the sum of the data transmission loss duration and the duration required to determine the tuning parameters. The data transmission loss duration includes the loss duration when transmitting data between the protocol stack and the transceiver, the loss duration when transmitting data between the transceiver and the control module, and the loss duration when transmitting data between the control module and the antenna tuner.

[0093] In some embodiments, a timer can be set to monitor in real time whether the timer's duration has reached a first duration.

[0094] In one example, for the case of calculating tuning parameters, see [link to example]. Figure 4 The diagram shows the antenna tuning strategy. The control module calculates the tuning parameters for a duration of duration A, and the data transmission loss duration is duration B. The first duration is duration C. When the timer's timing duration reaches the first duration C, the protocol stack needs to send a frequency band switching command to the target antenna to switch the target antenna's operating frequency band to the target frequency band.

[0095] In this case, see Figure 5 The flowchart of the antenna tuning method shown is executed by an electronic device. See [link / reference]. Figure 5 The method includes the following steps:

[0096] In step S501, in response to the frequency band switching request, the protocol stack generates a tuning command and sends the tuning command to the control module.

[0097] In step S502, in response to the tuning command, the control module uses a preset algorithm to calculate the tuning parameters and tunes the antenna tuner based on the tuning parameters so that the tuned state of the antenna tuner matches the target frequency band.

[0098] Step S503: Determine whether the timer duration has reached the first duration. If the timer duration has not reached the first duration C, continue to execute step S503. If the timer duration has reached the first duration, execute step S504.

[0099] In step S504, the protocol stack sends a frequency band switching command to the target antenna to switch the operating frequency band of the target antenna to the target frequency band.

[0100] In another example, for querying pre-stored tuning parameters, see [link to example]. Figure 6The diagram shows the antenna tuning strategy. The duration of the tuning parameters queried from the control module is duration D, and the duration of data transmission loss is duration B. The first duration is duration E. When the timer's timing duration reaches the first duration E, the protocol stack needs to send a frequency band switching command to the target antenna to switch the target antenna's operating frequency band to the target frequency band.

[0101] In this case, see Figure 7 The flowchart of the antenna tuning method shown is executed by an electronic device. See [link / reference]. Figure 7 The method includes the following steps:

[0102] In step S701, in response to the frequency band switching request, the protocol stack generates a tuning command and sends the tuning command and current scene information to the control module.

[0103] In step S702, in response to the tuning command, the control module queries the stored tuning information for tuning parameters that match the current scene information, and tunes the antenna tuner based on the tuning parameters so that the tuned state of the antenna tuner matches the target frequency band.

[0104] Step S703: Determine whether the timer duration has reached the first duration. If the timer duration has not reached the first duration E, continue to execute step S703. If the timer duration has reached the first duration, execute step S704.

[0105] Step S704: The protocol stack sends a frequency band switching command to the target antenna to switch the operating frequency band of the target antenna to the target frequency band.

[0106] In some embodiments, for the two methods described above, either method can be selected to determine the tuning parameters in actual use. Alternatively, the method of querying the tuning parameters that match the current scene information from the stored tuning information can be preferred. If no matching tuning parameters are found, the tuning parameters are then calculated.

[0107] The method provided in this disclosure indicates that the tuning of the antenna tuner is complete when the timing duration reaches the first duration. Afterward, the operating frequency band of the target antenna can be switched to the target frequency band, ensuring that the target antenna performs frequency band switching after tuning is complete. This avoids synchronization problems of the antenna tuner and signal interruption or signal jumps during frequency band switching, improving the user experience. Furthermore, tuning parameters matching the current scene information can be retrieved from stored tuning information, reducing the time spent calculating tuning parameters, increasing the speed of obtaining tuning parameters, and thus improving the tuning speed of the antenna tuner.

[0108] Figure 8 This is a flowchart illustrating an antenna tuning method according to an exemplary embodiment, performed by an electronic device. See also... Figure 8 The method includes the following steps:

[0109] Step S801: In response to the frequency band switching request, a tuning command is generated.

[0110] The implementation method of step S801 is similar to that of step S301 described above, and will not be repeated here.

[0111] In step S802, in response to the tuning command, the control module tunes the antenna tuner so that the tuned state of the antenna tuner matches the target frequency band.

[0112] The implementation method of step S802 is similar to that of step S303 described above, and will not be repeated here.

[0113] In step S803, the control module determines that the tuning of the antenna tuner is complete and sends a processing completion message to the protocol stack.

[0114] The processing completion information indicates that the antenna tuner has been tuned.

[0115] In some embodiments, the control module reads the current tuning state of the antenna tuner; in response to the current tuning state being the tuned state, the control module determines that the tuning of the antenna tuner is complete. That is, the control module determines whether the antenna tuner is tuned by judging whether the current tuning state of the antenna tuner is the tuned state based on the tuning parameters. If the current tuning state is the tuned state, it is determined that the tuning of the antenna tuner is complete; if the current tuning state is not the tuned state, it is determined that the tuning of the antenna tuner is not yet complete.

[0116] In some embodiments, in response to the interval between the current time and the second time reaching the second duration, the control module determines that the tuning of the antenna tuner is complete. Here, the second time is the moment when the control module sends tuning parameters to the antenna tuner, and the second duration is the sum of the time consumed by the control module in transmitting data to the antenna tuner and the time required to tune the antenna tuner based on the tuning parameters; this second duration is a preset duration. If the interval between the current time and the second time reaches the second duration, it indicates that the tuning of the antenna tuner is complete; if the interval between the current time and the second time does not reach the second duration, it indicates that the tuning of the antenna tuner is not yet complete.

[0117] In actual processing, either of the two methods mentioned above can be selected as needed to determine whether the tuning of the antenna tuner has been completed.

[0118] In some embodiments, the control module sends processing completion information to the protocol stack via the MIPI (Mobile Industry Processor Interface) protocol or GPIO (General-Purpose Input / Output) interrupt signals. Alternatively, the control module synchronizes processing completion information to the main system via the MIPI protocol or GPIO interrupt signals.

[0119] Optionally, the control module sends processing completion information to the transceiver via the MIPI protocol or GPIO interrupt signal, and the transceiver then forwards the processing completion information to the protocol stack.

[0120] See one example. Figure 9 The diagram shown illustrates the antenna tuning strategy. Figure 9 As can be seen, a closed-loop feedback system has been introduced. The control module sends processing completion information to the transceiver through the GPIO interrupt signal, and then the transceiver forwards the processing completion information to the protocol stack.

[0121] In step S804, in response to receiving the processing completion information, the protocol stack switches the operating frequency band of the target antenna to the target frequency band.

[0122] In some embodiments, in response to receiving processing completion information, the protocol stack sends a frequency band switching command to the target antenna to switch the operating frequency band of the target antenna to the target frequency band. The frequency band switching command indicates the target frequency band after the target antenna has switched.

[0123] See one example. Figure 10 The flowchart of the antenna tuning method shown is executed by an electronic device. See [link / reference]. Figure 10 The method includes the following steps:

[0124] In step S1001, in response to the frequency band switching request, the protocol stack generates a tuning command and sends the tuning command to the control module.

[0125] In step S1002, in response to the tuning command, the control module determines the tuning parameters and tunes the antenna tuner based on the tuning parameters so that the tuned state of the antenna tuner matches the target frequency band.

[0126] Step S1003: Determine whether the tuning of the antenna tuner is complete. If it is determined that the tuning of the antenna tuner is not complete, continue to execute step S1003. If it is determined that the tuning of the antenna tuner is complete, execute step S1004.

[0127] In step S1004, the control module sends a processing completion message back to the protocol stack.

[0128] In step S1005, in response to receiving the processing completion information, the protocol stack sends a frequency band switching command to the target antenna to switch the operating frequency band of the target antenna to the target frequency band.

[0129] The method provided in this disclosure allows the control module to send tuning completion information to the protocol stack after determining that the tuning of the antenna tuner is complete. Then, the protocol stack can switch the operating frequency band of the target antenna to the target frequency band, ensuring that the target antenna can switch frequency bands after tuning is complete. This avoids the synchronization problem of the antenna tuner and the problem of signal interruption or signal jump when frequency band switching occurs, thereby improving the user experience.
