[0036] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0037] The embodiments of the present application can provide an impedance matching method, device and storage medium. In practical applications, the impedance matching method can be implemented by an electronic device, and each functional entity in the electronic device can be collaboratively implemented by hardware resources of a computer device (such as a terminal device, a network device, etc.), such as computing resources such as a processor, and communication resources (such as for supporting various communication methods such as optical cables and cellular).

[0038] Of course, the embodiments of the present application are not limited to being provided as methods and hardware, and there may be multiple implementation methods, such as being provided as a storage medium (storing instructions for executing the impedance matching method provided by the embodiments of the present application).

[0039] The following describes various embodiments of the impedance matching method, device, and storage medium provided in the embodiments of the present application.

[0040] like Figure 1As shown, the electronic device 100 provided in the embodiment of the present application includes: a target tuner 101 and a target antenna 102, wherein the target antenna supports one frequency band and may also support multiplexing of at least two frequency bands, and the target tuner 101 is connected to the target antenna 102, and is used to adjust the input impedance of the target antenna so that the input frequency of the target antenna is kept as consistent as possible with the input impedance of the transmitter.

[0041] In practical applications, the electronic device 100 may include N antennas, and accordingly, include N tuners, one antenna is connected to one antenna tuner, and N is a positive number greater than or equal to 1. If the value of N is 1, the antenna included in the electronic device is the target antenna, and if the value of N is greater than 1, the target antenna is any one of the multiple antennas included in the electronic device. The tuner, which may also be called an antenna tuner, is an impedance network composed of resistors, capacitors, or inductors. The impedance network includes a tuner switch for controlling the connection or disconnection of each resistor, capacitor, and inductor in the impedance network, thereby changing the topological structure of the impedance network. In an embodiment of the present application, the topological structure of the impedance network can be controlled by the tuner configuration parameters, so that the antenna can be tuned to different working states based on different tuner configuration parameters to adapt to different scenarios.

[0042] The impedance matching method provided in the embodiment of the present application can be as follows Figure 2 As shown, including:

[0043] S201. An electronic device determines a first frequency band and a second frequency band based on a first parameter and the first frequency band has an efficiency difference, wherein the first frequency band and the second frequency band are two different frequency bands multiplexed on a target antenna.

[0044] The target antenna is any antenna of the electronic device, and the first frequency band and the second frequency band are two different frequency bands of the multiplexed target antenna, wherein the target antenna can be multiplexed on at least two frequency bands. If the target antenna is multiplexed on two frequency bands, one of the two frequency bands is the first frequency band and the other frequency band is the second frequency band; if the target antenna is multiplexed on at least three frequency bands, the first frequency band and the second frequency band are two frequency bands of the at least three frequency bands multiplexed on the target antenna, and at this time, the first frequency band and the second frequency band can be two randomly selected frequency bands, or two frequency bands selected based on a set selection strategy.

[0045] The electronic device communicates using the first frequency band and the second frequency band through the target antenna, thereby determining the value of the first parameter of the first frequency band and the value of the first parameter of the second frequency band, and determining the efficiency difference of the first frequency band based on the value of the first parameter of the first frequency band and the value of the first parameter of the second frequency band.

[0046] In the embodiment of the present application, the first parameter includes reference signal receiving power (RSRP), antenna efficiency, equivalent isotropically radiated power (EIRP), and other parameters that can characterize the efficiency of the antenna in the corresponding frequency band. The first frequency band efficiency difference of the present application can be understood as the difference between the frequency band efficiency of the first frequency band determined by the first parameter and the frequency band efficiency of the second frequency band, wherein the frequency band efficiency can be understood as the efficiency of the antenna in the corresponding frequency band.

[0047] In one example, the target antenna is multiplexed on frequency band 1 and frequency band 2, and the first parameter is RSRP, the RSRP identifier of frequency band 1 is RSRP1, and the RSRP identifier of frequency band 2 is RSRP2, then the electronic device determines the first frequency band efficiency difference between the first frequency band and the second frequency band based on RSRP1 and RSRP2.

[0048] S202. The electronic device determines a target second band efficiency difference corresponding to the first band efficiency difference among at least two second band efficiency differences, different second band efficiency differences among the at least two second band efficiency differences correspond to different tuner configuration parameters, the second band efficiency difference is a band efficiency difference determined based on a second parameter and inverse to the first band efficiency difference, and the first parameter and the second parameter are two different parameters characterizing the band efficiency.

[0049] At least two second frequency band efficiency differences are stored in the electronic device, and each of the at least two second frequency band efficiency differences corresponds to a tuner configuration parameter. In one example, the at least two second frequency band efficiency differences include: second frequency band efficiency difference 1, second frequency band efficiency difference 2, second frequency band efficiency difference 3, and second frequency band efficiency difference 4, second frequency band efficiency difference 1 corresponds to tuner configuration parameter 1, second frequency band efficiency difference 2 corresponds to tuner configuration parameter 2, second frequency band efficiency difference 3 corresponds to tuner configuration parameter 3, and second frequency band efficiency difference 4 corresponds to tuner configuration parameter 5.

[0050] In the embodiment of the present application, the second frequency band efficiency difference is the difference between the frequency band efficiencies of the second frequency band and the first frequency band determined based on the second parameter, and the determination of the first frequency band efficiency difference and the second frequency band efficiency difference is inverse. For example: the first frequency band and the second frequency band are respectively one of frequency band A and frequency band B, the first frequency band efficiency difference is the frequency band efficiency difference of frequency band A relative to frequency band B based on the first parameter, and the first frequency band efficiency difference is the frequency band efficiency difference of frequency band B relative to frequency band A based on the second parameter. For another example: the first frequency band and the second frequency band are respectively one of frequency band A and frequency band B, the first frequency band efficiency difference is the frequency band efficiency difference of frequency band B relative to frequency band A based on the first parameter, and the first frequency band efficiency difference is the frequency band efficiency difference of frequency band A relative to frequency band B based on the second parameter.

[0051] In an embodiment of the present application, the second parameter and the first parameter are two different parameters used to characterize the efficiency of the frequency band. The second parameter includes parameters that are different from the first parameter, such as RSRP, antenna efficiency, EIRP, etc., which can characterize the efficiency of the antenna in the corresponding frequency band. In one example, the first parameter is RSRP and the second parameter is antenna efficiency. In one example, the first parameter is antenna efficiency and the second parameter is RSRP. In one example, the first parameter is RSRP and the second parameter is EIRP. In one example, the first parameter is EIRP and the second parameter is antenna efficiency.

[0052] The electronic device determines a target second band efficiency difference corresponding to the first band efficiency difference from at least two second band efficiency differences based on the first band efficiency difference.

[0053] The electronic device can determine the target second frequency band efficiency difference using the second frequency band efficiency difference that is closest to the first frequency band efficiency difference among at least two second frequency band efficiency differences, and can also introduce the concept of frequency difference level to determine the frequency difference level of the first frequency band efficiency difference, and determine the target second frequency band efficiency difference using the second frequency band efficiency difference corresponding to the frequency difference level among at least two second frequency band efficiency differences.

[0054] S203: The electronic device controls a target tuner to adjust the input impedance of the target antenna by using a tuner configuration parameter corresponding to the target second frequency band efficiency difference, wherein the target tuner is a tuner of the target antenna.

[0055] After the electronic device determines the target second frequency band efficiency difference, it determines the tuner configuration parameters corresponding to the target second frequency band efficiency difference as the target tuner configuration parameters, controls the target tuner through the target tuner configuration parameters, and uses the target tuner configured as the target tuner configuration parameters to adjust the input impedance of the antenna.

[0056] In the embodiment of the present application, the electronic device may determine the first frequency band efficiency difference in one or more of the following situations, i.e., at least one of them, and determine the corresponding target tuner configuration parameter based on the first frequency band efficiency difference:

[0057] Timing to determine the first frequency band efficiency difference;

[0058] determining that the first frequency band has poor efficiency when the position of the electronic device varies greatly;

[0059] Based on received user actions;

[0060] A change in the communication scenario of the electronic device is detected.

[0061] The impedance matching method provided in the embodiment of the present application determines a first frequency band efficiency difference between a first frequency band and a second frequency band based on a first parameter, wherein the first frequency band and the second frequency band are two different frequency bands multiplexed on a target antenna; determines a target second frequency band efficiency difference corresponding to the first frequency band efficiency difference among at least two second frequency band efficiency differences, wherein different second frequency band efficiency differences among at least two second frequency band efficiency differences correspond to different tuner configuration parameters, wherein the second frequency band efficiency difference is a frequency band efficiency difference determined based on a second parameter and inverse to the first frequency band efficiency difference, wherein the first parameter and the second parameter are two different parameters characterizing the frequency band efficiency; and utilizes the The tuner configuration parameters corresponding to the target second frequency band efficiency difference are used to control the target tuner to adjust the input impedance of the target antenna, and the target tuner is a tuner of the target antenna; the target second frequency band efficiency that balances the first frequency band efficiency is determined, and the configuration parameters corresponding to the target second frequency band efficiency are used as configuration parameters for controlling the target tuner to adjust the impedance matching of the target antenna, so as to select configuration parameters from multiple configuration parameters according to the frequency band efficiency under the external communication environment, and the selected configuration parameters of the control tuner can ensure the balance between the first parameter and the second parameter, so as to adapt to the complex and changeable external communication environment in which the electronic device is located.

[0062] In some embodiments, S201 determines the first frequency band efficiency difference between the first frequency band and the second frequency band based on a first parameter, including: determining that the value of the first parameter of the first frequency band is a first value; determining that the value of the first parameter of the second frequency band is a second value; and determining the difference between the first value and the second value as the first frequency band efficiency difference.

[0063] The electronic device determines a value of a first parameter in a first frequency band, determines a value of the first parameter in a second frequency band, and determines the efficiency difference in the first frequency band by subtracting the second value from the first value.

[0064] In an example, the first parameter is RSRP, the RSRP of the first frequency band is marked as RSRP1, the RSRP of the second frequency band is marked as RSRP2, the efficiency difference of the first frequency band is marked as B, and B=RSRP1-RSRP2.

[0065] In the embodiment of the present application, the difference in the same parameter of two frequency bands is used to determine the frequency band efficiency difference of the two frequency bands, which can simply and quickly determine the frequency band efficiency difference and reduce the implementation complexity of the solution.

[0066] In some embodiments, the electronic device is also used to perform the following processing: comparing the first value and the second value with the reference threshold value corresponding to the first parameter respectively; wherein, when at least one of the first value and the second value is lower than the reference threshold value corresponding to the first parameter, the difference between the first value and the second value is determined as the efficiency difference of the first frequency band.

[0067] After determining the first value and the second value, the electronic device compares the first value and the second value with a reference threshold value corresponding to the first parameter, that is, the first threshold value, respectively. The comparison result includes one of the following:

[0068] Comparison result 1: both the first value and the second value are greater than or equal to the first threshold value;

[0069] Comparison result 2: at least one of the first value and the second value is smaller than the first threshold value, that is, one of the first value and the second value is smaller than the first threshold value or both are smaller than the first threshold value.

[0070] If the comparison result is comparison result one, it indicates that the communication efficiency of the first frequency band and the second frequency band are both relatively strong, and there is no need to reconfigure the tuner. The electronic device maintains the tuner configuration parameters currently used by the target tuner and does not change the topology of the target tuner, that is, the input impedance of the target antenna is not changed.

[0071] If the comparison result is comparison result two, which indicates that the communication efficiency of at least one of the first frequency band and the second frequency band is poor, the tuner needs to be reconfigured. At this time, the electronic device determines the efficiency difference of the first frequency band based on the first value and the second value, and controls, i.e. configures, the target tuner with the target tuner configuration parameters determined based on the efficiency difference of the first frequency band. The configuration at this time can be understood as reconfiguration, and the configuration parameters used by the target tuner are updated from the current tuner configuration parameters to the target tuner configuration parameters.

[0072] It is understandable that based on the different first parameters, the reference threshold value used is different. If the first parameter is RSRP, the reference threshold value is the RSRP threshold value. If the first parameter is antenna efficiency, the reference threshold value is the antenna efficiency threshold value. If the first parameter is EIRP, the reference threshold value is the EIRP threshold value.

[0073] In the embodiment of the present application, whether the configuration parameters of the target tuner need to be reconfigured is determined based on the reference threshold value corresponding to the first parameter, thereby avoiding unnecessary reconfiguration.

[0074] In some embodiments, determining the first frequency band efficiency difference between the first frequency band and the second frequency band based on the first parameter in S201 also includes: determining the differentiated frequency band efficiency difference corresponding to the first frequency band and the second frequency band, the differentiated frequency band efficiency difference representing the differentiated efficiency requirements of the first frequency band and the second frequency band; and updating the first frequency band efficiency difference based on the differentiated frequency band efficiency difference.

[0075] After determining the first frequency band efficiency difference based on the first value and the second value, determine whether there is a differentiated efficiency requirement between the first frequency band and the second frequency band. If there is no differentiated efficiency requirement between the first frequency band and the second frequency band, determine the target second frequency band efficiency difference directly based on the first frequency band efficiency difference. If there is a differentiated efficiency requirement between the first frequency band and the second frequency band, update the first frequency band efficiency difference based on the differentiated frequency band efficiency that characterizes the differentiated efficiency requirement between the first frequency band and the second frequency band to obtain an updated first frequency band efficiency difference, and determine the target second frequency band efficiency difference based on the updated first frequency band efficiency difference.

[0076] Whether there is a differentiated efficiency requirement between the first frequency band and the second frequency band represents whether the first frequency band and the second frequency band have the same requirements for communication efficiency. For example: the first frequency band and the second frequency band both have transmitting and receiving functions, and the expected frequency band efficiencies of the first frequency band and the second frequency band are the same, then there is no differentiated efficiency requirement between the two. For another example: the first frequency band has transmitting and receiving functions, the second frequency band only has a transmitting function but does not have a receiving function, and the expected frequency band efficiencies of the first frequency band and the second frequency band are different, then there are differentiated efficiency requirements between the two. For another example: the first frequency band is used for communication between an electronic device and a first base station, and the second frequency band is used for communication between an electronic device and a second base station, and the first base station and the second base station are at different distances from the electronic device, and the expected frequency band efficiencies of the first frequency band and the second frequency band are different, then there are differentiated efficiency requirements between the two. In the embodiment of the present application, factors affecting whether there are differentiated efficiency requirements for the first frequency band and the second frequency band include, but are not limited to, the functions of the frequency bands, which will not be repeated here.

[0077] In an embodiment of the present application, if there is a differentiated efficiency requirement between the first frequency band and the second frequency band, the electronic device determines the differentiated frequency band efficiency difference, and updates the first frequency band efficiency difference based on the differentiated frequency band efficiency difference. The first frequency band efficiency difference is marked as B, and the differentiated frequency band efficiency difference is marked as C, then the updated B is the B before the update plus C. Wherein, in the case where the difference between the first value and the second value is taken as the first frequency band efficiency difference, the differentiated efficiency requirement of the first frequency band relative to the second frequency band is determined as the differentiated frequency band efficiency difference. If the efficiency requirement of the first frequency band is greater than the efficiency requirement of the second frequency band, the value of C is positive, and if the efficiency requirement of the first frequency band is lower than the efficiency requirement of the second frequency band, the value of C is negative.

[0078] In the embodiment of the present application, the efficiency difference of the first frequency band is updated by using the differentiated frequency band efficiency difference, so as to meet the multi-band scenario in which there are differentiated efficiency requirements between the first frequency band and the second frequency band, and accurately determine the configuration parameters of the tuner in the scenario to ensure the balance of efficiency between the first frequency band and the second frequency band.

[0079] In some embodiments, the first parameter is reference signal received power RSRP, and determining the first frequency band efficiency difference between the first frequency band and the second frequency band based on the first parameter includes: receiving a first signal on the first frequency band through the target antenna; receiving a second signal on the second frequency band through the target antenna; and determining the first frequency band efficiency difference based on the RSRP of the first signal and the RSRP of the second signal.

[0080] When the first parameter is RSRP, the electronic device receives signals sent by the base station based on the first frequency band and the second frequency band at the same time, wherein the signal received based on the first frequency band is the first signal, and the signal received based on the second frequency band is the second signal. The electronic device determines the RSRP of the first signal, i.e., RSRP1, and determines the RSRP of the second signal, i.e., RSRP2, and B is obtained by subtracting RSRP2 from RSRP1.

[0081] In the embodiment of the present application, different terminal holding scenarios and different communication modes can affect the RSRP of the signal received by the electronic device. RSRP is used as the first parameter to determine the first frequency band efficiency difference, which can be independent of the holding scenario, communication mode and other interference factors on the frequency band efficiency. The frequency band efficiency difference is judged based on RSRP, the source of these interference factors affecting the frequency band efficiency. Starting from the root, the situation when multiple frequency bands are working simultaneously can be determined by comparing the strength of multiple signals. It is no longer limited to the balance of a certain scenario limited by the current technology, and basically all scenarios can improve the balance of multiple signals.

[0082] The terminal holding scenario includes but is not limited to: one-hand holding, two-hand holding, etc. The communication mode includes but is not limited to: Carrier Aggregation (CA) mode, multi-Subscriber Identity Module (MSIM) mode.

[0083] In some embodiments, S202 determines a target second band efficiency difference corresponding to the first band efficiency difference among at least two second band efficiency differences, including: determining a target band efficiency difference level corresponding to the first band efficiency difference among at least two band efficiency difference levels, wherein the first band efficiency difference range of the first band efficiency difference is divided into the at least two band efficiency difference levels, and the at least two second band efficiency differences are divided into the at least two band efficiency difference levels according to size; determining the second band efficiency difference corresponding to the target band efficiency difference level among the at least two second band efficiency differences as the target second band efficiency difference level.

[0084] In an embodiment of the present application, the range of possible values ​​of the first frequency band efficiency difference is called the first frequency band efficiency range of the first frequency band efficiency difference, and the electronic device divides the first frequency band efficiency range into at least two frequency band efficiency difference levels, and the electronic device also divides the at least two second frequency band efficiency differences into at least two frequency band efficiency difference levels based on the size of the efficiency difference of at least two second frequency ranges, and the number of frequency band efficiency difference levels divided by the first frequency band efficiency difference range is the same as the number of frequency band efficiency difference levels divided by the at least two second frequency band efficiency differences, and corresponds one to one.

[0085] In one example, at least two second frequency band efficiency differences include: E1, E2, E3, E4 and E5, E1 to E5 increase in sequence, the value granularity of E1, E2, E3, E4 and E5 is 1, and the value range is 10-10. The at least two second frequency band efficiency differences are divided into the following six frequency band efficiency difference levels: level 1 corresponding to E1 (less than E1), level 2 corresponding to E2 (based on between E1 and E2), level 3 corresponding to E3 (between E2 and E3) and level 4 (between E3 and E4), level 5 corresponding to E4 (between E4 and E5), and level 6 corresponding to E5 (between E6 and E7). ), and level 6 (greater than E5) corresponding to E5; the first frequency band efficiency difference range is -1 to 1, then -1 to -1 is divided into six frequency band efficiency difference levels: level 1 (between -1 and -0.6), level 2 (between -0.6 and -0.3), level 3 (between -0.3 and 0), level 4 (between 0 and 0.3), level 5 (between 0.3 and 0.6) and level 6 (between 0.6 and 1); if the first frequency band efficiency difference is 0.5, the first frequency band efficiency belongs to level 5, and the target second frequency difference is the second frequency band efficiency difference corresponding to level 5: E4.

[0086] In an embodiment of the present application, if the efficiency range of the first frequency band is the same as the range formed by at least two second frequency band efficiencies, the value range of the first frequency band efficiency corresponding to the same level may be the same as the value range of the second frequency band efficiency. In one example, the efficiency differences of at least two second frequency bands include: E1, E2, E3, E4 and E5, E1 to E5 increase in sequence, and the value granularity of E1, E2, E3, E4 and E5 is 1, and the value range formed is 10-10. The efficiency differences of at least two second frequency bands are divided into the following six frequency band efficiency difference levels: Level 1 corresponding to E1 (less than E1), Level 2 corresponding to E2 (based on between E1 and E2), Level 3 corresponding to E3 (between E2 and E3) and Level 4 (between E3 and E4), Level 5 corresponding to E4 (between E4 and E5). E5), and level 6 corresponding to E5 (greater than E5); the first frequency band efficiency difference range is -10 to 10, then 10 to -10 is divided into six frequency band efficiency difference levels: level 1 (less than E1), level 2 (based on between E1 and E2), level 3 (between E2 and E3), level 4 (between E3 and E4), level 5 (between E4 and E5), and level 6 (greater than E5); if the first frequency band efficiency difference is 2, the first frequency band efficiency belongs to level 3, and the target second frequency difference is the second frequency band efficiency difference corresponding to level 3: E3.

[0087] In the embodiment of the present application, one frequency band efficiency difference level corresponds to one second frequency band efficiency difference, and the second frequency band efficiency differences corresponding to different frequency band efficiency difference levels are the same or different.

[0088] In an embodiment of the present application, the first band efficiency range and the second band efficiency range are divided into the same number of band efficiency difference levels, and the target second band efficiency difference is determined based on the band efficiency difference levels, which can adapt to the situation where the value granularity of the first band efficiency difference and the second band efficiency difference is the same or different.

[0089] In the embodiment of the present application, at least two second frequency band efficiency differences and the configuration parameters corresponding to each second frequency band efficiency difference may be pre-configured, or may be obtained by the electronic device through actual debugging.

[0090] In some embodiments, the electronic device further performs the following processing:

[0091] The following processing is performed on each of the at least two tuner configuration parameters to obtain the at least two second frequency band efficiency differences: when the tuner configuration parameter acts on the target tuner, it is detected that the value of the second parameter of the first frequency band is a third value, and it is detected that the value of the second parameter of the second frequency band is a fourth value; the difference between the fourth value and the third value is determined as the second frequency band efficiency difference corresponding to the tuner configuration parameter.

[0092] Here, the electronic device determines at least two second frequency band efficiency differences by detecting the efficiency difference between the first frequency band and the second frequency band based on the second parameter when the target tuner uses different configuration parameters. At this time, the at least two second frequency band efficiencies are obtained by the electronic device through debugging.

[0093] During the debugging phase, the electronic device obtains at least two configuration parameters and applies the at least two configuration parameters to the target tuner respectively, thereby controlling the antenna to communicate under the control of the target tuner with a different network structure.

[0094] For each configuration parameter, when the target tuner is configured with the configuration parameter, the electronic device receives signals in the first frequency band and the second frequency band through the target antenna, and detects the value of the second parameter of the first frequency band to obtain a third value, and detects the value of the second parameter of the second frequency band to obtain a fourth value, and the electronic device subtracts the third value from the fourth value to obtain the second frequency band efficiency difference corresponding to the configuration parameter. Here, the second frequency band efficiency difference is the value of the second parameter of the second frequency band minus the value of the second parameter of the first frequency band, and the first frequency band efficiency difference is the value of the first parameter of the first frequency band minus the value of the first parameter of the second frequency band, so the second frequency band efficiency difference is the inverse of the first frequency band efficiency difference.

[0095] In the embodiment of the present application, the second frequency band efficiency difference corresponding to each configuration parameter is determined based on a reverse idea, so that the selected configuration parameters can adapt to the reverse first frequency band efficiency difference and second frequency band efficiency difference, thereby achieving a balance in the frequency band efficiency of the first frequency band and the second frequency band.

[0096] In some embodiments, if the target antenna is reused in at least three frequency bands, the electronic device also performs the following processing: detecting the value of the first parameter of each of the at least three frequency bands; comparing the value of the first parameter of each of the at least three frequency bands, and selecting two frequency bands with the largest and smallest values ​​of the first parameter, wherein one of the two selected frequency bands is the first frequency band and the other is the second frequency band.

[0097] If the target antenna is multiplexed on at least three frequency bands, when the electronic device communicates through the target antenna, it communicates through at least three frequency bands at the same time, and at this time, at least three signals are received simultaneously. The electronic device can detect the first parameter of each signal in the at least three signals, compare the magnitudes of the first parameters of each signal, and determine the first parameter with the largest value and the first parameter with the smallest value, and use the frequency band to which the first parameter with the largest value belongs and the frequency band to which the first parameter with the smallest value belongs as two measured frequency bands, and use one of the two measured frequency bands as the first frequency band and the other as the second frequency band.

[0098] In an embodiment of the present application, when the target antenna is multiplexed in at least three frequency bands, the three frequency bands are combined in pairs for a configuration parameter. During the debugging phase, it is determined that the efficiency difference of the second frequency band of the two combined frequency bands is based on the second parameter.

[0099] In one example, the target antenna is multiplexed on frequency band 1, frequency band 2, and frequency band 3, and the electronic device determines the values ​​of the first parameters of frequency band 1, frequency band 2, and frequency band 3, the largest value is frequency band 1, and the smallest value is frequency band 3, then the first frequency band efficiency difference is determined based on the value of the first parameter of frequency band 1 and the value of the first parameter of frequency band 3, and the target second frequency band efficiency difference is selected based on the second frequency band efficiency difference of frequency band 1 and frequency band 3.

[0100] In an embodiment of the present application, when the target antenna is reused in at least three frequency bands, the configuration parameters are selected based on the frequency band with the largest value of the first parameter and the two frequency bands with the smallest values ​​of the first parameter, which can ensure that the selected target configuration parameters meet the performance requirements of each frequency band.

[0101] The impedance matching method provided in the embodiment of the present application is further described below.

[0102] Antenna tuner is an impedance matching network that connects the transmitter and antenna. It can match the impedance between the transmitter and the antenna, so that the antenna has the maximum radiated power at any frequency. The antenna input impedance changes greatly with the frequency of the antenna, while the transmitter output impedance is constant. If the transmitter is directly connected to the antenna, when the transmitter frequency changes, the impedance between the transmitter and the antenna does not match, which will reduce the radiated power. Using an antenna tuner can match the impedance between the transmitter and the antenna, so that the antenna has the maximum radiated power at any frequency.

[0103] The antenna tuner is composed of a network of inductors and capacitors. One end is the signal source end, which is connected to one end of the transmitter, and the other end is the load end, which is connected to one end of the antenna. If the voltage standing wave ratio measured at the input end of the antenna tuner is too large, it means that the two ends are mismatched. It is necessary to change the tap of the inductor and the capacity of the capacitor to make the voltage standing wave ratio close to 1:1. From the basic principle, the antenna tuner has two functions: one is to compensate the entire load end that is not in a resonant state to resonance through series and parallel inductors and capacitors; the other is that after resonance, if the input impedance of the load end is not equal to the output impedance of the signal source end, the voltage standing wave ratio between the load end and the signal source end is adjusted by changing the transmission coefficient of the antenna tuner to achieve matching. Therefore, the antenna tuner is also called an antenna coupler.

[0104] Electronic devices require antenna tuner switches, and the increasing number of frequency bands, functions, and modes required for electronic devices to operate has made the design of Radio Frequency (RF) front end (RFFE) increasingly complex. As CA, 4x4 Multiple-Input Multiple-Output (MIMO), Wi-Fi MIMO, and new broadband 5G bands are used to provide higher data rates, electronic devices use more antennas. The number of antennas in electronic devices has increased from four fingers and six to eight or more. As the number of antennas increases, the space available for mobile system antennas decreases, resulting in reduced antenna efficiency. Compared with 4G electronic devices, the number of new frequency bands that 5G electronic devices must support has increased significantly. Due to the complexity of the design, more and more antenna tuners need to be used on a single antenna, and adding antenna tuners helps optimize the overall antenna performance of each band. Each antenna has an inherent resonant frequency at which maximum antenna efficiency can be achieved. Tuning can be achieved by placing a parallel capacitor device (to lower the resonant frequency) or a parallel inductor device (to increase the resonant frequency) on the antenna. Using multiple capacitors and inductors, the antenna can be tuned to multiple frequencies via an antenna tuner switch, allowing some of the lost performance to be recovered through antenna tuning. Without tuning, the antenna performs well over a limited frequency range, but adding an antenna tuner switch allows for more optimized performance over a wider frequency range.

[0105] The method for performing antenna tuning of an electronic device includes: Figure 3 The Aperture Tuner and Figure 4 The impedance tuning (Impedance Tuner) shown in Figure 3 Neutralization Figure 4 In the example, the antenna 301 is a planar inverted F-shaped antenna (PIFA). The antenna 301 is connected to the RF front end (FE) 303 via a feeder 302. Figure 3 In the embodiment, the tuner 304 is connected to the antenna 301 at position 305. Figure 4 In FIG. 3 , tuner 304 is located between feed 302 and RF FE. Figure 3 and Figure 4As shown. The antenna tuning components are placed in different positions. Among them, aperture tuning optimizes the total antenna efficiency from the free space in the middle of the antenna, and can optimize the antenna efficiency across multiple frequency bands. Aperture tuning has a great impact on the antenna efficiency of both transmitting and receiving communication applications. Depending on the application, the total radiated power (TRP) and total isotropic sensitivity (TIS) can be improved by 3dB or more. It should be noted that Figure 3 and Figure 4 The tuner switch in the tuner 304 is a single-pole four-throw (SP4T). In practical applications, the tuner switch in the tuner can be selected according to requirements.

[0106] In the related art, aperture tuning is used in electronic devices to overcome the problems caused by reduced antenna area and efficiency, or a combination of aperture tuning and impedance tuning is used to support an ever-expanding frequency band range.

[0107] In the actual design of mobile terminals, when multiple frequency bands reuse the same antenna, the antenna tuner is generally configured in multiple states, such as: Figure 5 In the embodiment, the RF front end 501 is connected to the antenna 503 through the tuner 502. If the antenna 503 supports N28 and N41, then N28 and N41 reuse the same antenna 503, and the tuner 502 will be configured into three working states, one for N28 to work independently, one for N41 to work independently, and one for N28+N41 to work simultaneously. As shown in Table 1, if the working state of the tuner is that N28 works independently, the configuration of the tuner is configuration 1 (Config1), if the working state of the tuner is that N41 works independently, the configuration of the tuner is configuration 2 (Config2), and if the working state of the tuner is that N28+N41 works simultaneously, the configuration of the tuner is configuration 3 (Config3). When the working state of the electronic device is configured as N28+N41 working simultaneously, the principle of balance is adopted, that is, the performance of the two frequency bands will be balanced, and the performance of 28 and 41 will be equal and consistent when config3 is configured as much as possible; the two frequency bands will have the same efficiency in free space or other usage scenarios;

[0108] Table 1. Relationship between tuner working status and configuration parameters

[0109] Working status N28 N41 N28+N41 Tuner Configuration Config1 Config2 Config3

[0110] In the related art, the configuration parameters of the tuner when multiple frequency bands work simultaneously are relatively rigid; only balanced configuration debugging is performed for free space or a single scenario, which cannot cover the current external environment where communications are extremely changeable and complex.

[0111] Common scenarios for users include hand-held (hand-held includes single-handed and double-handed), head-hand, etc., and communication scenarios include CA and dual SIM cards. Only making a balanced configuration for a certain scenario cannot meet the communication needs of users in multiple scenarios. A complete communication link, such as Figure 6 As shown, it includes: a radio frequency front end 501, an antenna tuner 502, an antenna 503, and a base station 504, wherein the radio frequency front end 501, the antenna tuner 502, and the antenna 503 are located in the electronic device, and the air interface transmission between the antenna 503 and the base station 504, that is, the space transmission supports frequency bands including N28 and N41. Figure 6 The complete communication link shown has several locations that cause signal differences:

[0112] Position ①: In CA mode, the base station transmits different powers for the two frequency bands. When dual-SIM cards are working, the two frequency bands are transmitted by two different base stations, and the base station power difference is even greater.

[0113] Position ②, spatial transmission loss is different;

[0114] Position ③, antenna reception differences, different scenarios such as free space, hand-held, etc. cause different differences;

[0115] Position ④, conduction link loss difference;

[0116] Position ⑤: Difference in signal demodulation caused by RFFE.

[0117] In the related technologies, the current technology can only make the difference very low in a certain scenario in position ③, and the differences in other places cannot be solved at all.

[0118] The impedance matching method of the present application is described below by taking the first parameter as RSRP and the second parameter as antenna efficiency as an example. The impedance matching method provided in the embodiment of the present application includes the following steps:

[0119] Step 1: Let A = antenna efficiency of frequency band 1 - antenna efficiency of frequency band 2 (taking antennas supporting N28 and N41 as an example, A is the difference between the antenna efficiency of n28 and the antenna efficiency of n41).

[0120] After debugging the tuner in free space, different configurations achieve the effects shown in Table 2, and record each config for subsequent calls:

[0121] Table 2. Efficiency difference corresponding to the configuration parameters of the debugging

[0122] Tuner Configuration Config0 Config1 Config2 Config3 Config4 Config5 Config6 Poor efficiency A0＝0 A1＝3 A2＝6 A3＝9 A4＝-9 A5＝-6 A6＝-3

[0123] Step 2: Monitor the RSRP of the two frequency bands at all times.

[0124] The signal sent by the base station will pass through the terminal antenna after being received Figure 7 The link shown includes: antenna 503, tuner 502, RF FE503, radio frequency transceiver 505 and modem 506, wherein the frequency is down-converted at the radio frequency transceiver 505, and the signal is demodulated at modem 506. Modem 506 can monitor the RSRP of the received signal at all times, and observe the quality of the signals in the two frequency bands at all times through RSRP.

[0125] Step 3: Select tuner logic.

[0126] Let B = RSRP_Band 2 (hereinafter referred to as RSRP2) - RSRP_Band 1 (hereinafter referred to as RSRP1), where B represents the difference between the RSRP of Band 2 and the RSRP of Band 1.

[0127] The logic of the logic selection is as follows Figure 8 As shown:

[0128] S801, configure the tuner configuration parameters to config0 by default;

[0129] S802. Determine whether RSRP1 and RSRP2 are both greater than or equal to -80 dBmm.

[0130] When the RSRP of band 2 or band 1 is detected to be higher than -80dBm, the tuner is configured to config0; because when the RSRP is higher than -80dBm, the signal is very strong and no additional action is required to balance the signal. When the RSRP of band 2 or the RSRP of band 1 is detected to be lower than -80dBm, S803 is executed to start the tuner reconfiguration mechanism.

[0131] Here, the first threshold value is -80dBmm. In practical applications, the type of the first threshold value may change with the change of the first parameter, and the size of the first threshold value may be set according to demand and is not limited to -80.

[0132] S803 : Determine B based on RSRP1 and RSRP2, and compare B with A.

[0133] After entering the reconfiguration detection mechanism, compare the RSRP of band 2 with that of band 1, and reconfigure the tuner based on the amplitude value. When the RSRP of band 2, RSRP2, is higher than the RSRP of band 1, RSRP1, it indicates that the signal strength of band 2 is better than that of band 1. Reconfigure the tuner logic based on the degree of excellence and check the range of the difference B in A (for example, when B=4, the tuner logic is adjusted to config1). That is, reconfigure the two signals through tuner reconfiguration to make the two signal strengths as relatively balanced as possible - the difference between the two signals determines the logic of the reverse difference; where B=RSRP2-RSRP1. When the difference is too large, no further adjustment will be made. Excessive adjustment of the signal strength of a certain band will cause disconnection (such as 9dB in this design. After exceeding 9dB, the config used for 9dB will still be called). Figure 8 As shown in 804:

[0134] If A6<B≤A1, the Tuner configuration is config0;

[0135] If A1<B≤A2, the Tuner configuration is config1;

[0136] If A2<B≤A3, the Tuner configuration is config2;

[0137] If A3<B, then determine that the Tuner configuration is config3;

[0138] If A5<B≤A6, the Tuner configuration is config6;

[0139] If A4<B≤A5, the Tuner configuration is config5;

[0140] If B≤A4, the Tuner configuration is config4.

[0141] The impedance matching method provided in the embodiment of the present application starts from the root and determines the situation when multiple frequency bands work simultaneously by constantly comparing the strength of multiple signals. It is no longer limited to the balance of a certain scene limited by current technology, and can basically improve the balance of multiple signals in all scenes, including but not limited to the user's holding method, that is, the holding method, and the communication mode (CA / MSIM).

[0142] Scenario optimization for users: When a user holds a terminal, the terminal antenna will be blocked, causing the signal to weaken significantly. The attenuation of signals of different frequencies is different, resulting in performance differences in the frequency bands of multiplexed antennas. The handheld mode can be divided into single-handed holding, two-handed holding horizontally, and head-hand holding. The scenarios are complex and changeable. This solution can be well optimized according to the performance of each scenario, so as to maintain a balanced state at all times.

[0143] Communication mode of scenario optimization: In CA state, equalization can better perform CA transmission, and multiple frequency bands can be received in a balanced manner to avoid the situation where the signal strength of multiple frequency bands is too different, resulting in the weak signal band being overwhelmed by the strong signal, causing abnormal CA throughput and even damage to the receiving device; in MSIM state, it is equivalent to the CA state optimization; in MSIM dual-card mode, the received frequency bands come from different base stations, and the difference in received signal strength will be greater. This equalization tuning scheme can realize signal strength tuning when the dual-card frequency bands reuse the antenna.

[0144] The impedance matching method provided in the embodiment of the present application introduces an intelligent identification switching mechanism, such as Fig. 9 As shown in the figure, the frequency band efficiency B determined based on RSRP is the signal difference between the two frequency bands, and the frequency band efficiency A determined based on antenna efficiency is the tuning compensation of the two frequency bands. The final configuration parameters are determined by balancing A and B. The pre-configured tuner logic is intelligently matched; compared with the current fixed and rigid tuner logic, it can achieve balanced optimization in all scenarios; effectively avoid the reduction of throughput, network disconnection, and device damage caused by the large difference in signal strength of multiple frequency bands.

[0145] The impedance matching method provided in the embodiment of the present application can also be applied to including but not limited to the following scenarios 1 and 2.

[0146] Scenario 1: Threshold Adjustment

[0147] Figure 8 The solution shown is aimed at absolute balance, so that the signal strength of multiple frequency bands is the same when they are demodulated by the modem through the same antenna as much as possible; some designs require customized thresholds, such as when there are two frequency bands of a reused antenna, one frequency band is used for both transmission and reception, and the other frequency band is only used for reception. The efficiency of the frequency band with transmission and reception functions is better than the efficiency of the frequency band with only reception function. In this case, a customized threshold is required. Assuming that the efficiency of the expected transmission frequency band is C (C = frequency band 2 efficiency - frequency band 1 efficiency, when the efficiency of the expected frequency band 2 is relatively high, C is a positive value, otherwise it is a negative number) dB higher than that of the reception frequency band, the corresponding switching threshold needs to increase the additional quantity C, and D is set as B+C. In this case, the logic of the logic selection is as follows Fig.10 As shown:

[0148] S1001, configure the tuner configuration parameters to config0 by default;

[0149] S1002. Determine whether RSRP1 and RSRP2 are both greater than or equal to -80 dBmm.

[0150] When the RSRP of band 2 or band 1 is detected to be higher than -80dBm, the tuner is configured to config0. When the RSRP of band 2 or band 1 is detected to be lower than -80dBmm, S1003 is executed to start the tuner reconfiguration mechanism.

[0151] S1003: Compare the sizes of D and A.

[0152] D=B+C. It can be understood that B is the efficiency difference between band 1 and band 2 determined based on the RSRP value, and D can be understood as the updated first band efficiency difference obtained by updating B based on the differentiated band efficiency difference C.

[0153] like Fig.10 As shown in 1004:

[0154] If A6<D≤A1, the Tuner configuration is config0;

[0155] If A1<D≤A2, the Tuner configuration is config1;

[0156] If A2<D≤A3, the Tuner configuration is config2;

[0157] If A3<D, the Tuner configuration is config3;

[0158] If A5<D≤A6, the Tuner configuration is config6;

[0159] If A4<D≤A5, the Tuner configuration is config5;

[0160] If D≤A4, the Tuner configuration is config4.

[0161] Scene 2

[0162] The scenario where more frequency bands reuse the same antenna. The above example mainly uses two frequency bands to reuse the same ant. When more than two frequency bands reuse the same antenna, the situation will become more complicated, such as when the same antenna supports 3CA, 4CA, etc. At this time, the tuner needs to pre-configure more scenarios, and then call the corresponding tuner logic according to the specific differences. This expansion is theoretically consistent with the logic call of the above two frequency bands, but more tuner configurations need to be added to meet the more complex multi-band balance requirements.
