[0045] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0046] In the description of the present disclosure, the terms used, such as "first", "second", etc., are used to distinguish similar objects and do not have to be understood as a specific order or sequence. In addition, in the description with reference to the accompanying drawings, the same symbols in different drawings represent the same elements unless otherwise stated.

[0047] Although operations or steps are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood that it is required to perform these operations or steps in the specific order shown or in a serial order, or to perform all the operations or steps shown to obtain the desired results. In the embodiments of the present disclosure, these operations or steps can be performed in series; these operations or steps can also be performed in parallel; or some of these operations or steps can be performed.

[0048] The related art usually configures the antenna tuner according to the parameters of the electronic device, wherein the antenna tuner configuration is used to adjust the uplink and downlink radiation efficiency within the antenna operating frequency range, that is, it is achieved by configuring different matching of the antenna feed end. For example, antenna tuning is achieved by using different capacitance values ​​and inductance combinations of adjustable capacitors and adjustable inductors. The main purpose of related art tuning is to achieve a balance between uplink and downlink efficiency.

[0049] In addition, the tuner configurations for single band and combined band are also different. For single band, the tuner configuration can be determined based on the channel and bandwidth of the current band. Specifically, a fixed antenna tuner parameter can be configured, or a unique tuner parameter can be configured based on the current band + channel + bandwidth + antenna impedance.

[0050] Optionally, for a combined band, such as DLCA (Downlink inter-band CA, carrier aggregation for downlink transmission), the tuner configuration can be determined based on the current two band combinations + channel + bandwidth. Specifically, a fixed antenna tuner parameter can be configured, or a unique tuner parameter can be configured based on the current band combination + channel + bandwidth + antenna impedance.

[0051] In summary, electronic devices can adjust the tuner according to their own parameter configuration, and the adjustment goal is "balanced uplink and downlink antenna efficiency", which does not take into account the strength relationship between uplink and downlink signals in the actual network. When electronic devices work in an actual network, such as when using FDD (Frequency Division Duplex) uplink and downlink frequency division multiplexing bands, it will cause imbalance in uplink and downlink signals in the actual network.

[0052] As an example, if in an actual network, the margin of the downlink signal of an electronic device is much larger than the margin of the uplink signal, the use of related technical tuning will limit the uplink signal earlier, leading to problems such as limited uplink voice and dropped calls. For example, the attenuation of the uplink in the network is larger than that of the downlink, resulting in a small uplink signal margin. Another example is to meet SAR (Specific Absorption Rate) compliance → reduce the maximum transmit power of electronic equipment → electronic equipment uplink is limited → uplink signal margin is small.

[0053] As another example, if the margin of the uplink signal of an electronic device in an actual network is much larger than the margin of the downlink signal, tuning using related technologies will cause the downlink signal to be limited earlier, leading to problems such as downlink voice limitation and call drops. For example, the attenuation of the downlink frequency band link in the network is larger than that of the uplink, resulting in a small uplink signal margin.

[0054] In view of the above problems, the embodiments of the present disclosure provide an antenna tuning method, device, electronic device and storage medium that can effectively solve the imbalance problem between uplink signals and downlink signals.

[0055] The application environment of an antenna tuning method provided by this embodiment is described below. Figure 1 As shown, the application environment may include an electronic device 11 and a network device 12. The electronic device 11 and the network device 12 may be connected in a wired or wireless manner.

[0056] The electronic device 11 may be a user equipment (UE), a mobile station (MS), a mobile terminal (MT), a handheld or wearable communication device, etc. Specifically, the electronic device 11 may be a mobile phone, a tablet computer, a watch, or a computer with a wireless transceiver function, or a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a smart home, a vehicle-mounted terminal, etc.

[0057] In the embodiment of the present application, the device for implementing the function of the electronic device 11 may be an electronic device, or may be a device capable of supporting the electronic device to implement the function, such as a chip system (e.g., a chip, or a processing system composed of multiple chips). The following takes the device for implementing the function of the electronic device as the electronic device 11 as an example to describe the antenna tuning method provided in the embodiment of the present application.

[0058] The network device 12 may include access network equipment (base station) and may also include core network equipment, etc. The network device 12 may be used to implement functions such as resource scheduling, wireless resource management, and wireless access control of the electronic device 11. Specifically, the network device 12 may be any of a small base station, a wireless access point, a transmission receive point (TRP), a transmission point (TP), and some other access nodes.

[0059] Figure 2 is a flow chart of an antenna tuning method according to an exemplary embodiment. Figure 2 As shown, the antenna tuning method may include steps S21 to S22.

[0060] In step S21, configuration data of an antenna tuner is determined according to an uplink efficiency of the electronic device and a downlink efficiency of the electronic device.

[0061] In the disclosed embodiment, the uplink efficiency of the electronic device may also be referred to as the margin of the uplink signal, the margin of the uplink link, or the uplink margin, etc. Similarly, the downlink efficiency of the electronic device may also be referred to as the margin of the downlink signal, the margin of the downlink link, or the downlink margin, etc.

[0062] In some embodiments, the uplink efficiency of the electronic device can be determined by the current transmit power, maximum transmit power, and modulation mode of the electronic device. Specifically, the embodiment of the present disclosure can obtain the maximum transmit power and actual transmit power of the electronic device, and obtain the uplink efficiency based on the maximum transmit power and the actual transmit power. Exemplarily, uplink efficiency = Power_max-Power_requeted. Among them, Power_max can be the maximum transmit power, Power_requeted can be the current transmit power of the electronic device, which can be the uplink power that the electronic device needs to transmit at the current moment.

[0063] In other implementations, the downlink efficiency of the electronic device may be determined by RSRP (Reference Signal Receiving Power), SNR (Signal to Noise Ratio), and modulation mode of the signal currently received by the electronic device. Specifically, the embodiment of the present disclosure may obtain the actual reference signal received power and the actual signal to noise ratio of the electronic device, and on this basis, obtain the downlink efficiency according to the actual reference signal received power and the actual signal to noise ratio.

[0064] In addition, in the process of obtaining the downlink efficiency according to the actual reference signal received power and the actual signal-to-noise ratio of the electronic device, the embodiment of the present disclosure can determine a first difference between the actual reference signal received power and the preset reference signal received power, and determine a second difference between the actual signal-to-noise ratio and the preset signal-to-noise ratio. On this basis, the downlink efficiency is determined based on the first difference and the second difference.

[0065] As an example, downlink efficiency = S1*(rsrp_current-rsrp_sensitivity)+S2(snr_current-snr_sensitivity), where "rsrp_current" is the actual reference signal received power, which can be obtained through actual real-time measurement; "rsrp_sensitivity" is the preset reference signal received power, which can be obtained through actual measurement before leaving the factory and stored in the electronic device; "snr_current" is the actual signal-to-noise ratio, which can also be obtained through actual real-time measurement, and "snr_sensitivity" is the preset signal-to-noise ratio, which can be obtained through actual measurement before leaving the factory and stored in the electronic device. It can be seen that the downlink efficiency can be the difference between the current downlink received signal strength and the sensitivity.

[0066] As an optional method, when it is determined that the electronic device is connected to an actual network or a callbox, the embodiment of the present disclosure can obtain the uplink efficiency and downlink efficiency of the electronic device through actual measurement. On this basis, the configuration data of the antenna tuner is determined according to the uplink efficiency of the electronic device and the downlink efficiency of the electronic device.

[0067] As an optional method, the embodiment of the present disclosure can obtain the configuration data of the antenna tuner corresponding to the uplink efficiency of the electronic device and the downlink efficiency of the electronic device. Here, the configuration data of the antenna tuner can be tuner configuration parameters, which can include different capacitance values ​​of the adjustable capacitor and different inductance values ​​of the adjustable inductor, etc.

[0068] For example, by applying different voltages to the voltage-controlled capacitor, different capacitance values ​​can be selected, and by applying different voltages to the adjustable inductor, different inductance values ​​can be selected. In addition, the disclosed embodiment can select N capacitor and inductor combinations through a switch to obtain a variety of parameter configurations, each of which can correspond to different radiation efficiencies.

[0069] As an optional method, the disclosed embodiment can directly obtain the configuration data of the antenna tuner corresponding to the uplink efficiency of the electronic device and the downlink efficiency of the electronic device, or first obtain the difference between the uplink efficiency of the electronic device and the downlink efficiency of the electronic device, and on this basis, determine the configuration data of the antenna tuner corresponding to the difference. The specific method of obtaining the configuration data of the antenna tuner according to the uplink efficiency of the electronic device and the downlink efficiency of the electronic device will be described in detail in the following embodiments, and will not be repeated here.

[0070] In step S22, an antenna tuning operation is performed based on the configuration data.

[0071] As an optional method, after obtaining the configuration data of the antenna tuner, the embodiment of the present disclosure can perform antenna tuning operations based on the configuration data of the antenna tuner, thereby solving the imbalance problem of uplink and downlink signals in the actual network, and further reducing the problem of poor service of electronic equipment such as calls and data.

[0072] The disclosed embodiments can solve the problem of imbalance between uplink and downlink signals in an actual network by determining corresponding antenna configuration data based on the uplink efficiency and downlink efficiency of the electronic device. Specifically, the configuration data of the antenna tuner is determined according to the uplink efficiency and the downlink efficiency of the electronic device, and the antenna tuning operation is performed based on the configuration data, thereby ensuring the balance of the uplink and downlink signals.

[0073] Figure 3 is a flow chart of an antenna tuning method according to an exemplary embodiment. Figure 3 As shown, the antenna tuning method may include steps S31 to S32.

[0074] In step S31, in the configuration correspondence, configuration data corresponding to the uplink efficiency of the electronic device and the downlink efficiency of the electronic device is acquired.

[0075] As an optional method, the embodiment of the present disclosure may search for configuration data corresponding to the uplink efficiency of the electronic device and the downlink efficiency of the electronic device in the configuration correspondence relationship. Prior to this, the embodiment of the present disclosure may first obtain the configuration correspondence relationship, which may be a configuration parameter lookup table, which may include the relationship between the uplink efficiency, the downlink efficiency and the configuration data.

[0076] Specifically, for a specified Band or Band combination, the disclosed embodiment can obtain the antenna uplink efficiency and downlink efficiency corresponding to different tuner configurations through simulation or actual measurement to obtain a tuner configuration table (configuration correspondence). Exemplarily, the tuner configuration table can be a lookup table of uplink efficiency, downlink efficiency, and uplink and downlink efficiency delta.

[0077] In addition, the total number of tuner configurations can be determined as needed. Here, the efficiency delta can be directly built into the table or obtained through real-time calculation. It should be noted that different tables can be configured separately for different Bands / Channels / antennas, that is, the uplink efficiency, downlink efficiency, and uplink and downlink efficiency delta corresponding to different Bands may be different; the uplink efficiency, downlink efficiency, and uplink and downlink efficiency delta corresponding to different Channels may be different; the uplink efficiency, downlink efficiency, and uplink and downlink efficiency delta corresponding to different antennas may also be different.

[0078] In the embodiment of the present disclosure, the configuration data can be represented by an index, that is, different indexes correspond to different configuration data. In other words, the configuration data in the configuration correspondence can be represented by actual configuration data, such as N inductors and M capacitors, or different configuration data can be represented by corresponding indexes. At this time, there can be a mutual mapping relationship between the configuration data and the index. The embodiment of the present disclosure uses the index as an example to represent the configuration data, as shown in Table 1.

[0079] Table 1

[0080] Index Band Channel Uplink efficiency Downlink efficiency 0 Band1 18300 efficient_u_1 efficient_d_1 1 Band1 18300 efficient_u_2 efficient_d_2 2 Band1 18300 efficient_u_3 efficient_d_3 … … … … … M Band1 18300 efficient_u_M efficient_d_M … … … … … N Band1 18300 efficient_u_N efficient_d_N

[0081] Table 1 shows that the configuration data of the antenna tuner corresponding to different combinations of uplink efficiency and downlink efficiency may be different. For example, when the uplink efficiency is efficient_u_2 and the downlink efficiency is efficient_d_2, the configuration data of the corresponding antenna tuner may be index 1. For another example, when the uplink efficiency is efficient_u_M and the downlink efficiency is efficient_d_M, the configuration data of the corresponding antenna tuner may be index M.

[0082] In addition, the configuration correspondence may also include the relationship between the frequency band (Band) and the configuration data, and / or the relationship between the channel (Channel) and the configuration data, that is, if the frequency band and / or channel are different under the same combination of uplink efficiency and downlink efficiency, the corresponding antenna tuner configuration data will also be different. For example, the uplink efficiency is efficient_u_2, the downlink efficiency is efficient_d_2, and when the frequency band is Band1, the corresponding antenna tuner configuration data may be index 1. For another example, the uplink efficiency is efficient_u_2, the downlink efficiency is efficient_d_2, and when the frequency band is Band2, the corresponding antenna tuner configuration data may be index 11. The above examples are for illustration only and are not explicitly limited. The specific implementation is based on actual conditions.

[0083] It should be noted that the uplink and downlink for the embodiments of the present disclosure may be different frequency systems, that is, the uplink efficiency and the downlink efficiency may be different. For example, the embodiments of the present disclosure may be applied to the FDD system or the GSM (Global System of Mobile communication) system.

[0084] As another optional method, the configuration correspondence may also include an efficiency difference value. In the process of obtaining the configuration data of the antenna tuner, the embodiment of the present disclosure may determine the efficiency difference value between the uplink efficiency and the downlink efficiency, and then search the configuration data corresponding to the efficiency difference value in the configuration correspondence relationship. In this case, the configuration correspondence relationship may be as shown in Table 2.

[0085] Table 2

[0086] Index Band Channel Uplink efficiency Downlink efficiency Efficiency delta 0 Band1 18300 efficient_u_1 efficient_d_1 a 1 Band1 18300 efficient_u_2 efficient_d_2 b 2 Band1 18300 efficient_u_3 efficient_d_3 c … … … … … … M Band1 18300 efficient_u_M efficient_d_M m … … … … … … N Band1 18300 efficient_u_N efficient_d_N n

[0087] The efficiency delta in Table 2 may be equal to L1*uplink efficiency-L2*downlink efficiency, where L1 and L2 may be auxiliary coefficients, which may be used to adjust the uplink / downlink weights. Here, L1 and L2 may be determined by actual debugging data.

[0088] As an optional method, when determining the efficiency difference between the uplink efficiency and the downlink efficiency, the embodiment of the present disclosure may first obtain the uplink weight corresponding to the uplink efficiency, and obtain the downlink weight corresponding to the downlink efficiency. On this basis, the first efficiency is determined according to the uplink efficiency and the uplink weight corresponding to the uplink efficiency, and the second efficiency is determined according to the downlink efficiency and the downlink weight corresponding to the downlink efficiency, and the efficiency difference is determined based on the first efficiency and the second efficiency. For example, delta_uplink and downlink margin = L1*uplink efficiency-L2*downlink efficiency.

[0089] In summary, the embodiments of the present disclosure can configure the tuner based on the actual performance of the uplink and downlink, that is, a close value can be found according to the efficiency delta column in the configuration correspondence between the uplink efficiency and the downlink efficiency, thereby determining the tuner configuration currently required.

[0090] It should be noted that the disclosed embodiment can determine the configuration data of the antenna tuner according to the uplink efficiency and the downlink efficiency, or can determine the configuration data of the antenna tuner by combining the uplink efficiency, the downlink efficiency and the parameters of the electronic device. The parameters of the electronic device may include at least one of the operating frequency of the electronic device, the operating bandwidth of the electronic device and the antenna impedance in the electronic device. By combining the parameters of the electronic device and the uplink and downlink efficiencies, the configuration data finally obtained can be more accurate.

[0091] It should also be noted that when the configuration data is obtained using the parameters of the electronic device and the uplink and downlink efficiencies, if there is a conflict between the configuration data determined by the two, the embodiment of the present disclosure can use the configuration data determined by the uplink and downlink efficiencies as the main one, so as to ensure the real-time nature of data acquisition and better meet the actual needs of users. For example, the first configuration data is obtained based on the parameters of the electronic device, and the second configuration data is determined based on the uplink efficiency and the downlink efficiency, and the first configuration data and the second configuration data are different, then the embodiment of the present disclosure can use the second configuration data as the target configuration data and perform the antenna tuning operation based on the target configuration data.

[0092] In step S32, an antenna tuning operation is performed based on the configuration data.

[0093] As an optional manner, after acquiring the configuration data, the embodiment of the present disclosure may perform an antenna tuning operation based on the configuration data. Specifically, the uplink efficiency of the electronic device is improved based on the configuration data, or the downlink efficiency of the electronic device is improved based on the configuration data.

[0094] As a specific implementation, after obtaining the uplink efficiency and the downlink efficiency, the embodiment of the present disclosure can compare the two to determine whether the uplink margin is larger or the downlink margin is larger. If it is determined that the uplink efficiency is greater than the downlink efficiency, it means that the uplink margin is larger. At this time, the tuner can be adjusted to a better downlink configuration, that is, the downlink efficiency is improved based on the configuration data, that is, the receiving efficiency of the electronic device is improved, as detailed in Figure 4 As shown, Figure 4 Curve 41 in the figure represents the radiation efficiency of the antenna in the related technology within a frequency range, and curve 42 represents the radiation efficiency of the antenna in the present solution within a frequency range. By comparison, it can be seen that curve 42 gives priority to the downlink efficiency, which can better solve the problem of imbalanced uplink and downlink signals.

[0095] In other words, when the uplink efficiency is greater than the downlink efficiency, the configuration data of the antenna coordinator in the embodiment of the present disclosure gives priority to the downlink efficiency. On this basis, performing antenna tuning operations based on the acquired configuration data can achieve uplink and downlink margin balance, thereby solving the problem of downlink limitation, that is, solving the problem of downlink voice limitation, call drop, etc.

[0096] Optionally, if it is determined that the downlink efficiency is greater than the uplink efficiency, it means that the margin of the downlink is larger. At this time, the tuner can be adjusted to a better uplink configuration, that is, the uplink efficiency is improved based on the configuration data, that is, the transmission efficiency of the electronic device is improved, as described in detail. Figure 5 As shown, Figure 5 Curve 51 in the figure represents the radiation efficiency of the antenna in the related technology within a frequency range, and curve 52 represents the radiation efficiency of the antenna in the present solution within a frequency range. By comparison, it can be seen that curve 52 gives priority to the uplink efficiency, which can better solve the problem of imbalance between uplink and downlink signals.

[0097] In addition, during the antenna tuning operation, the embodiment of the present disclosure may condition the inductance value or the capacitance value based on the configuration data. Optionally, the embodiment of the present disclosure may also shut down or close one or n paths based on the configuration data. There is no explicit restriction on how to perform the antenna tuning operation, and it can be selected according to the actual situation.

[0098] In other words, when the downlink efficiency is greater than the uplink efficiency, the configuration data of the antenna coordinator in the embodiment of the present disclosure gives priority to the uplink efficiency. On this basis, performing antenna tuning operations based on the acquired configuration data can achieve uplink and downlink margin balance, thereby solving the uplink limitation, that is, solving the problems of uplink voice limitation, call drop, etc.

[0099] The disclosed embodiment can solve the problem of imbalance between uplink and downlink signals in an actual network by determining corresponding antenna configuration data based on the uplink efficiency and downlink efficiency of the electronic device. Specifically, the configuration data of the antenna tuner is determined according to the uplink efficiency of the electronic device and the downlink efficiency of the electronic device, and the antenna tuning operation is performed based on the configuration data, so that the balance of uplink and downlink signals can be ensured. In addition, the disclosed embodiment can obtain corresponding configuration data in combination with the efficiency difference value to solve the problem of imbalance between uplink and downlink signals in an actual network, thereby reducing the problem of poor service of electronic devices such as calls and data.
