Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0019] The technical solutions provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0020] like Figure 1 The diagram shown is a structural schematic of an electronic device provided in an exemplary embodiment of this application. The electronic device can be a terminal or other devices besides a terminal. For example, the electronic device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a server, network attached storage (NAS), personal computer (PC), television set (TV), ATM, or self-service machine, etc. This application embodiment does not specifically limit the scope of the device.

[0021] In this embodiment, the aforementioned electronic device may include a processor, a radio frequency (RF) front-end, and an antenna assembly. The processor is connected to the RF front-end and the antenna assembly, respectively, and the RF front-end is connected to the antenna assembly.

[0022] The processor, also known as an application processor, baseband, or baseband chip, is used for signal processing, radio frequency signal transmission and reception control, antenna tuning, etc.

[0023] The radio frequency front end may include Figure 1 The RF transceiver and RF front-end circuit shown are examples of such components.

[0024] The antenna assembly 13 includes Figure 1 The antenna and first switch shown are configured such that the antenna is divided into regions based on the magnitude of the instantaneous voltage (also known as peak voltage (Vpeak) or theoretical voltage) generated when a radio frequency signal passes through it. In this embodiment, the antenna may include a first region 131 and a second region 132. The voltage value (instantaneous voltage value or theoretical voltage) corresponding to the first region 131 is higher than the voltage value corresponding to the second region. Therefore, the first region 131 and the second region 132 can be respectively referred to as the theoretical high-voltage region and the theoretical low-voltage region. In one implementation, the voltage value corresponding to the first region 131 can be greater than or equal to 70V, such as 70V, 80V, 85V, etc., and the voltage value corresponding to the second region 132 can be less than 70V, such as 60V, 45V, 40V, etc.

[0025] In this case, considering that for the first region 131, if, as disclosed in the related art, only a switching device with a high withstand voltage value can be set in the first region 131 (generally, in order to ensure the reliability of the antenna system, the voltage that the switching device can withstand (i.e., withstand voltage value) is greater than the maximum peak voltage of the corresponding antenna region), then when the envelope voltage value of the signal to be transmitted (TX) is low, and the switching withstand voltage value of the first switch 133 set in the first region 131 is high, then there may be problems of low system efficiency and high power consumption of the antenna system.

[0026] Please refer to the following for details. Figure 2 In this embodiment, the signal to be sent (i.e. Figure 2 At the same time or before the data to be transmitted arrives at the antenna, the electronic device can be activated by the processor 11 (i.e., Figure 2 The baseband in the antenna obtains the signal to be transmitted and determines the envelope voltage value of the signal to be transmitted. Then, it generates a first control signal based on the envelope voltage value, so that the first switch 133 can control at least one of its withstand voltage mode and on / off state according to the first control information received (as sent by the processor 11), so as to realize the connection or disconnection between the radio frequency front-end 12 and the first region 131 of the antenna under different withstand voltage modes (such as low withstand voltage mode and high withstand voltage mode). That is, this application can flexibly adjust the withstand voltage mode of the first switch 133 set in the high voltage region through the antenna voltage pre-feedback method, so as to improve the overall efficiency of the antenna system and achieve the purpose of reducing system power consumption.

[0027] For example, since the smaller the R-on of the switching device ("R-on" is the radio frequency attribute of the switching device itself, i.e. the resistance value when the switching device is turned on), the smaller the insertion loss and the higher the antenna system efficiency, and the larger the R-on, the larger the insertion loss and the lower the antenna efficiency, when the envelope voltage value of the signal to be transmitted is low, this application can control the first switch 133 to switch to a low withstand voltage mode, thereby reducing the R-on of the first switch 133 and improving the antenna system efficiency. Correspondingly, when the envelope voltage value of the signal to be transmitted is high, this application can control the first switch 133 to switch to a high-voltage mode, thereby increasing the R-on of the first switch 133 and reducing the efficiency of the antenna system. However, considering that the antenna system efficiency is the same when the first switch 133 is in high-voltage mode, corresponding to the antenna tuning scheme in the related technology, this application, in combination with the antenna system efficiency and power consumption under different voltage modes of the first switch 133, can flexibly switch the voltage-resistant mode of the first switch 133 according to the envelope voltage value of the signal to be transmitted through pre-feedback, thereby improving the overall efficiency of the antenna system and reducing the overall power consumption of the antenna system, compared with the technical solutions in the related technology. It is worth noting that when the processor 11 and the first switch 133 transmit the first control information, a Universal Device Control Interface (MIPI) signal line (or MIPI control line) can be used to realize the transmission of the first control information. Here, the voltage resistance value of the switching device (such as the first switch) refers to the maximum peak voltage that the switching device can withstand, and the high-voltage mode or low-voltage mode mentioned in this application refers to the relatively high or low voltage resistance value of the switching device.

[0028] Of course, in this embodiment, when controlling at least one of the withstand voltage mode and on / off state of the first switch 133 through the first control information, the control method is different depending on the first switch 133. The implementation process is described below with reference to Example 1 and Example 2.

[0029] Example 1

[0030] Assuming the first switch 133 includes a multi-mode tuning switch, and the first control information may include switch control information and voltage withstand mode switching information, then the multi-mode tuning switch is used to connect or disconnect the first region 131 of the RF front-end 12 and the antenna according to the switch control information, and to switch between a first voltage withstand mode and a second voltage withstand mode according to the voltage withstand mode switching information, such as switching from the first voltage withstand mode to the second voltage withstand mode or from the second voltage withstand mode to the first voltage withstand mode, etc.; wherein, the voltage withstand mode switching information is determined based on the envelope voltage value of the signal to be transmitted, and the switch withstand voltage value corresponding to the first voltage withstand mode is higher than the switch withstand voltage value corresponding to the second voltage withstand mode.

[0031] For example, when the envelope voltage value of the signal to be transmitted is low, the processor 11 can determine that the withstand voltage mode switching information is a first withstand voltage mode switching to a second withstand voltage mode, and control the first switch 133 to switch to the second withstand voltage mode according to the withstand voltage mode switching information.

[0032] For example, when the envelope voltage value of the signal to be transmitted is high, the processor 11 determines that the withstand voltage mode switching information is a second withstand voltage mode switching to a first withstand voltage mode, and controls the first switch 133 to switch to the first withstand voltage mode according to the withstand voltage mode switching information.

[0033] It should be noted that in this embodiment, the switch control information can be determined based on the operating frequency of the antenna system, that is, the on / off state of the first switch 133 is bound or associated with the operating frequency of the antenna system. In other words, when the first switch 133 switches to a withstand voltage mode, the on / off control of the first switch 133 (i.e., the switch control information) is determined according to the operating frequency of the antenna system.

[0034] Example 2

[0035] Assuming the first switch 133 includes a first sub-switch and a second sub-switch connected in parallel, and the switching withstand voltage of the first sub-switch is higher than that of the second sub-switch, i.e. the first sub-switch is a high-voltage switch and the second sub-switch is a low-voltage switch, then the processor 11 generates first control information based on the envelope voltage value of the signal to be transmitted, so as to control the on / off state of the first sub-switch and the second sub-switch.

[0036] For example, assuming the envelope voltage value of the signal to be transmitted is low, the processor 11 sends the first control information to control the first sub-switch to be closed and the second sub-switch to be opened. Conversely, if the envelope voltage value of the signal to be transmitted is high, the processor 11 sends the first control information to control the first sub-switch to be opened and the second sub-switch to be closed. Thus, through voltage pre-feedback, the first sub-switch and the second sub-switch can be flexibly switched according to the envelope voltage value of the signal to be transmitted, thereby improving the overall efficiency of the antenna system.

[0037] Based on the foregoing, the antenna assembly 13 further includes: a second switch 134, connected between the radio frequency front-end 12 of the electronic device and the second region 132 of the antenna, for controlling the on / off state between the radio frequency front-end 12 and the first region 131 of the antenna according to the received first control information, wherein the switching withstand voltage of the second switch 134 is less than the switching withstand voltage of the first switch 133 in the first withstand voltage mode.

[0038] The fact that the withstand voltage of the second switch 134 is less than that of the first switch 133 in the first withstand voltage mode can be understood as follows: when the first switch 133 is in a high withstand voltage mode, the withstand voltage of the second switch is less than that of the first switch 133. For example, if the withstand voltage of the first switch is 80V, the withstand voltage of the second switch is 45V. However, in this embodiment, the withstand voltage of the second switch 134 is greater than the voltage value corresponding to the second region 132 (i.e., the instantaneous voltage generated when the radio frequency signal passes through the second region 132) to ensure the reliability of the antenna system.

[0039] Furthermore, in this embodiment, the second switch 134 can be a tuning switch and is connected in parallel with the first switch 133. Therefore, in this embodiment, the first control information for controlling the first switch 133 and the second control information for controlling the second switch 134 can be transmitted simultaneously via the MIPI signal line.

[0040] Furthermore, embodiments of this application also provide an antenna tuning method, executed by the hardware and / or software of the aforementioned electronic device, which may include, but is not limited to, the following steps.

[0044] S31-S33 can be implemented by, but is not limited to, a processor in an electronic device.

[0045] Optionally, sending the first control signal to the first switch to control the withstand voltage mode and / or on / off state of the first switch includes: when the first control information includes switch control information and withstand voltage mode switching information, controlling the first switch to switch from a first withstand voltage mode to a second withstand voltage mode or from a second withstand voltage mode to a first withstand voltage mode through the withstand voltage mode switching information, and controlling the first switch to connect or disconnect the first region of the radio frequency front end and the antenna through the switch control information; wherein the withstand voltage mode switching information is determined based on the envelope voltage value of the signal to be transmitted, and the withstand voltage value of the switch corresponding to the first withstand voltage mode is higher than the withstand voltage value of the switch corresponding to the second withstand voltage mode.
