[0007] This application provides an electronic device 1 according to one embodiment. The electronic device 1 may be a mobile phone, tablet computer, desktop computer, laptop computer, e-reader, handheld computer, electronic display screen, laptop computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phones, personal digital assistants (PDAs), augmented reality (AR) / virtual reality (VR) devices, media players, smart wearable devices, and other devices with antennas 10. In this embodiment, a mobile phone is used as an example for illustration and description; it should be understood that this should not be construed as limiting the embodiments of this application.

[0008] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 A perspective view of an electronic device provided according to an embodiment of this application; Figure 2 A partial structural schematic diagram of an electronic device provided in one embodiment; Figure 3 One implementation method Figure 1 The circuit block diagram of the electronic device provided is shown below. The electronic device 1 includes multiple antennas 10, a detector 20, and a control chip 30. All of the multiple antennas 10 support the same frequency band, wherein a first target antenna among the multiple antennas 10 serves as the transmitting antenna during a first time period. The detector 20 is used to identify the current scene in which the electronic device 1 is located. The control chip 30 is used to select a switching mode as a target switching mode from multiple switching modes based on the current frequency band supported by the multiple antennas 10 and the current scene, determine a second target antenna from the multiple antennas 10 using the target switching mode, and use the second target antenna as the transmitting antenna during a second time period, wherein the second time period is later than the first time period. If the second target antenna is different from the first target antenna, in the current scene, the transmission performance of the second target antenna as the transmitting antenna is superior to that of the first target antenna as the transmitting antenna.

[0009] In the schematic diagram of this embodiment, four antennas 10 are included in the electronic device 1 as an example. This should not be construed as a limitation on the electronic device 1 provided in this application. The electronic device 1 may include three or more than four antennas 10. For ease of description, the plurality of antennas 10 shown in the electronic device 1 include a first antenna 110, a second antenna 120, a third antenna 130, and a fourth antenna 140. The positions of the plurality of antennas 10 are different. The electronic device 1 has a first side 1a, a second side 1b, a third side 1c, and a fourth side 1d. The first side 1a, the second side 1b, the third side 1c, and the fourth side 1d are connected end-to-end in sequence. The length of the second side 1b is greater than the length of the first side 1a, and the length of the second side 1b is greater than the length of the third side 1c; correspondingly, the length of the fourth side 1d is greater than the length of the first side 1a, and the length of the fourth side 1d is greater than the side length of the third side 1c. If the electronic device 1 is in portrait mode, the first side 1a is the top side of the electronic device 1, the third side 1c is the bottom side of the electronic device 1, and the second side 1b and the fourth side 1d are the sides of the electronic device 1.

[0010] In the schematic diagram of this embodiment, the first antenna 110 is arranged corresponding to the first side 1a, the second antenna 120 is arranged corresponding to the second side 1b, the third antenna 130 is arranged corresponding to the third side 1c, and the fourth antenna 140 is arranged corresponding to the fourth side 1d as an example. This should not be construed as a limitation on the embodiment of this application. In other embodiments, the positions of the plurality of antennas 10 can be different. Different positions of the plurality of antennas 10 will result in different performances of the plurality of antennas 10 when the electronic device 1 is in the same orientation as a transmitting antenna. For example, when the electronic device 1 is in portrait mode and in free space, the performance of the first antenna 110 as a transmitting antenna may differ from that of the second antenna 120, the third antenna 130, and the fourth antenna 140 as transmitting antennas.

[0011] The same frequency band supported by the multiple antennas 10 may include Long Term Evolution (LTE), New Radio (NR), or Wireless Fidelity (WiFi).

[0012] During the first time period, the first target antenna among the plurality of antennas 10 serves as a transmitting antenna. In other words, the antenna 10 that functions to transmit uplink signals during the first time period is designated as the first target antenna. Understandably, in one embodiment, the first target antenna can be used to transmit uplink signals and also to receive downlink signals. In other words, during the first time period, the first target antenna serves both as a transmitting antenna to transmit uplink signals and as a receiving antenna 10 to receive downlink signals. There can be one, two, or more first target antennas. During the first time period, one or more of the remaining antennas 10 besides the first target antenna can serve as receiving antennas 10 to receive downlink signals.

[0013] The electronic device 1 has multiple scenarios, including a free space scenario, a one-handed holding scenario, a left-head-and-hand scenario, a right-head-and-hand scenario, a landscape mode scenario held with both hands, and a pocket mode scenario. The current scenario of the electronic device 1 is one of these scenarios.

[0014] The detector 20 may include, but is not limited to, sensors or user equipment (UE) devices. The user equipment includes, but is not limited to, a gyroscope, an earpiece, etc. For example, the gyroscope in the electronic device 1 is also used to identify whether the electronic device 1 is in landscape or portrait mode. The earpiece of the electronic device 1 is used to identify whether a person is in a head-and-hands call state.

[0015] The electronic device 1 has multiple switching modes, and the switching logic for switching the transmitting antenna differs among these modes. Even when the multiple antennas 10 of the electronic device 1 support the same current frequency band, the antenna 10 with optimal transmission performance will differ depending on the specific scenario. In other words, even when the multiple antennas 10 of the electronic device 1 support the same current frequency band, the optimal transmitting antenna 10 will differ depending on the scenario in which the electronic device 1 operates. Furthermore, even within the same scenario, the antenna 10 with optimal transmission performance may differ depending on the frequency bands supported by the multiple antennas 10 of the electronic device 1.

[0016] In this embodiment, the control chip 30 selects a switching mode as the target switching mode from multiple switching modes based on the current frequency band supported by the plurality of antennas 10 and the current scenario, and uses the target switching mode to determine the second target antenna from the plurality of antennas 10.

[0017] In one embodiment, the second target antenna is different from the first target antenna. If the second target antenna is different from the first target antenna, in the current scenario, the transmission performance using the second target antenna as the transmitting antenna is better than the transmission performance using the first target antenna as the transmitting antenna.

[0018] In another embodiment, the second target antenna is the same as the first target antenna. If the second target antenna is the same as the first target antenna, in the current scenario, the transmission performance of the first target antenna is superior to the transmission performance of the other antennas 10 among the other plurality of antennas 10.

[0019] In summary, the electronic device 1 provided in this application includes multiple antennas 10, a detector 20, and a control chip 30. All antennas 10 support the same frequency band. The detector 20 identifies the current scene in which the electronic device 1 is located. The control chip 30 selects a switching mode from multiple switching modes as a target switching mode based on the current frequency band supported by the multiple antennas 10 and the current scene. It also determines a second target antenna from the multiple antennas 10 using the target switching mode and uses the second target antenna as a transmitting antenna during a second time period. Therefore, the electronic device 1 provided in this application can improve the switching efficiency of the antennas 10 when the scene changes, and the transmission performance using the second target antenna as a transmitting antenna is better during the second time period, thereby improving the user experience of using the electronic device 1.

[0020] Please see Figure 4 , Figure 4 Another implementation Figure 1 The circuit block diagram of the electronic device provided is shown below. The electronic device 1 includes multiple antennas 10, a detector 20, a switching switch 40, and a control chip 30. The multiple antennas 10 all support the same frequency band, wherein, during a first time period, a first target antenna among the multiple antennas 10 serves as the transmitting antenna. The detector 20 is used to identify the current scene in which the electronic device 1 is located. The control chip 30 is used to select a switching mode as a target switching mode from multiple switching modes based on the current frequency band supported by the multiple antennas 10 and the current scene, determine a second target antenna from the multiple antennas 10 using the target switching mode, and use the second target antenna as the transmitting antenna during a second time period, wherein the second time period is later than the first time period. If the second target antenna is different from the first target antenna, under the current scene, the transmission performance of the second target antenna as the transmitting antenna is superior to that of the first target antenna as the transmitting antenna.

[0021] Furthermore, the electronic device 1 also includes a switching switch 40. The switching switch 40 is electrically connected to the plurality of antennas 10. The control chip 30 is electrically connected to the switching switch 40 to switch which of the plurality of antennas 10 serves as the transmitting antenna. For example, if the control chip 30 selects a switching method as the target switching method from multiple switching methods based on the current frequency band supported by the plurality of antennas 10 and the current scenario, it uses the target switching method to determine a second target antenna from the plurality of antennas 10, and uses the second target antenna as the transmitting antenna during a second time period. Specifically, if the second target antenna is different from the first target antenna, the control chip 30 controls the switching switch 40 to switch from the first target antenna to the second target antenna, so that the second target antenna is used as the transmitting antenna during the second time period. If the second target antenna is the same as the first target antenna, the control chip 30 controls the switching switch 40 to maintain its current state, so that the first target antenna is used as the second target antenna during the second time period.

[0022] Please see Figure 5 and Figure 6 , Figure 5 As another implementation method Figure 1 The circuit block diagram of the electronic device provided in the document; Figure 6 One implementation method Figure 5 The reference table stores multiple operating frequency bands, multiple scenarios, and corresponding switching methods in the memory. In the embodiment, the electronic device 1 includes multiple antennas 10, detectors 20, switching switches 40, and control chips 30. The multiple antennas 10, detectors 20, switching switches 40, and control chips 30 are described above and will not be repeated here.

[0023] Furthermore, in this embodiment, the electronic device 1 also includes a memory 50. The memory 50 stores switching modes corresponding to each of the multiple scenarios corresponding to each of the multiple operating frequency bands. The control chip 30 searches for a frequency band among the multiple operating frequency bands that is the same as the current frequency band as a target frequency band, searches for a scenario among the multiple scenarios under the target frequency band that matches the current scenario as a target scenario, and selects the switching mode corresponding to the target scenario as the target switching mode.

[0024] exist Figure 6In this illustration, three operating frequency bands are used as an example, and this should not be construed as a limitation on the implementation of this application. For ease of description, the multiple operating frequency bands are respectively named the first operating frequency band, the second operating frequency band, and the third operating frequency band. The illustration also uses four scenarios of the electronic device 1 as an example, and this should not be construed as a limitation on the implementation of this application. The multiple scenarios are respectively named the first scenario, the second scenario, the third scenario, and the fourth scenario. Generally speaking, "multiple" means two or more.

[0025] In the implementation, the switching method at the intersection of the row where the operating frequency band is located and the column where the scene is located is the switching method corresponding to the operating frequency band supported by the plurality of antennas 10 of the electronic device 1 and the scene where the electronic device 1 is located.

[0026] For example, the switching method at the intersection of the row where the first working frequency band is located and the column where the first scene is located is the third switching method; the switching method at the intersection of the row where the first working frequency band is located and the column where the second scene is located is the second switching method; the switching method at the intersection of the row where the first working frequency band is located and the column where the third scene is located is the first switching method; the switching method at the intersection of the row where the first working frequency band is located and the column where the fourth scene is located is the first switching method.

[0027] Among the multiple operating frequency bands, the frequency band that is the same as the current frequency band is the target frequency band. Among the multiple scenarios, the scenario that matches the current scenario is the target scenario. Therefore, the switching method corresponding to the target frequency band and the current scenario is the target switching method. For example, in this embodiment, the switching method at the intersection of the row where the target frequency band is located and the column where the current scenario is located is the target switching method. For instance, if the target frequency band is a second operating frequency band and the target scenario is a third scenario, then the first switching method corresponding to the second operating frequency band and the third scenario is the target switching method.

[0028] The electronic device 1 provided in this application embodiment further includes a memory 50, which stores switching methods corresponding to each of the multiple scenarios corresponding to each of the multiple operating frequency bands. Therefore, the control chip 30 can easily find the switching method corresponding to the current frequency band and the current scenario from the memory 50 as the target switching method, thereby improving the accuracy and convenience of determining the target switching method. The electronic device 1 provided in this application embodiment can select a suitable switching scheme according to the current frequency band and scenario changes, improving the switching efficiency of the antenna 10 and enhancing the user experience of using the electronic device 1.

[0029] In one embodiment, the plurality of switching methods includes at least two of a first switching method, a second switching method, and a third switching method, wherein the strategies for determining the second target antenna are all different for the first switching method, the second switching method, and the third switching method.

[0030] The different methods used to determine the second target antenna among the multiple switching methods enable the electronic device 1 to select a suitable switching scheme based on the current frequency band and scene changes when switching the transmitting antenna, thereby improving the switching efficiency of the antenna 10 and enhancing the user experience of using the electronic device 1.

[0031] The first switching method, the second switching method, and the third switching method will be described in detail below.

[0032] Please see Figure 7 , Figure 7 This is a reference table of target antennas in multiple scenarios corresponding to a first switching mode in one embodiment of this application. In one embodiment, the memory 50 further stores target antennas corresponding to each scenario in multiple scenarios corresponding to each of the multiple operating frequency bands of the first switching mode. The target antenna is one of the multiple antennas 10, and the transmission performance of the target antenna in the same operating frequency band and the same scenario is superior to the transmission performance of any other antenna 10 among the multiple antennas 10. If the first switching mode is selected as the target switching mode, the control chip 30 selects the target antenna corresponding to the target frequency band and the target scenario as the second target antenna.

[0033] In this embodiment, multiple scenarios within a specific operating frequency band in the first switching mode are described as examples. The left column lists the scenario categories, labeled as the first scenario (AP0 in the table), the second scenario (AP1 in the table), ... the (n+1)th scenario (APn in the table). The right column lists the antenna 10 combinations, i.e., the target antennas for the corresponding scenarios. In this embodiment, the target antenna includes one of the multiple antennas 10. For example, in this embodiment, the target antenna corresponding to AP0 is the first antenna 110 (Ant0 in the table), AP1 corresponds to the second antenna 120 (Ant1 in the table), and APn corresponds to the third antenna 130 (Ant2 in the table).

[0034] If the first switching mode is selected as the target switching mode, the control chip 30 selects the target frequency band and the target antenna corresponding to the target scene as the second target antenna. For example, in Figure 7 In the case where the current frequency band supported by the plurality of antennas 10 is Figure 7The operating frequency band shown; and if the target scenario is the first scenario (AP0), then the control chip 30 selects the first antenna 110 as the second target antenna. In other words, if the current frequency band supported by the plurality of antennas 10 is Figure 7 The operating frequency band shown; and if the target scenario is the first scenario (AP0), the control chip 30 controls the uplink antenna to switch to the first antenna 110 (Ant0). If the current frequency band supported by the plurality of antennas 10 is Figure 7 The operating frequency band shown; and if the target scenario is the second scenario (AP2), the control chip 30 controls the uplink antenna to switch to the second antenna 120 (Ant1).

[0035] If the target scenario is the second scenario (AP1), then the control chip 30 selects the second antenna 120 as the second target antenna. If the target scenario is the (n+1)th scenario (identified as scenario n), then the control chip 30 selects the third antenna 130 as the second target antenna.

[0036] The electronic device 1 provided in this application embodiment, if the first switching mode is selected as the target switching mode, the control chip 30 selects the target antenna corresponding to the target frequency band and the target scene as the second target antenna. The target antenna is one of the plurality of antennas 10, and the transmission performance of the target antenna in the same operating frequency band and the same scene is better than the transmission performance of any other antenna 10 among the plurality of antennas 10. Therefore, the electronic device 1 provided in this application embodiment can quickly determine the target frequency band and the target antenna corresponding to the target scene according to the first switching mode; thereby improving the efficiency of the electronic device 1 in switching transmission antennas.

[0037] Please see Figure 8 , Figure 8 This is a reference table of target antennas in multiple scenarios corresponding to a working frequency band of the first switching method in another embodiment of this application. In this embodiment, the memory 50 also stores target antennas corresponding to each scenario in multiple scenarios corresponding to each working frequency band of the first switching method. The target antenna is two of the multiple antennas 10, and the transmission performance of the target antenna in the same working frequency band and the same scenario is better than the transmission performance of any combination of the other two antennas 10. If the first switching method is selected as the target switching method, the control chip 30 selects the target frequency band and the target antenna corresponding to the target scenario as the second target antenna.

[0038] In this embodiment, for the first switching method, it is necessary to analyze and screen the electronic device 1 in the early stage to identify the optimal antenna 10 or antenna 10 combination for the current frequency band. It should be noted that the "early analysis and screening" mentioned here refers to analysis and screening performed during the research and development phase of the electronic device 1 and stored in the memory 50 of the electronic device 1. When the electronic device 1 is in use, it can directly access the reference table stored in the memory 50.

[0039] Understandably, in other embodiments, the target antenna may be two or more of the plurality of antennas 10, or any combination of the plurality of antennas 10.

[0040] In this embodiment, multiple scenarios within a specific operating frequency band in the first switching mode are described as examples. The left column lists the scenario categories, labeled as the first scenario (AP0 in the table), the second scenario (AP1 in the table), ... the (n+1)th scenario (APn in the table). The right column lists the antenna 10 combinations, i.e., the target antennas for the corresponding scenarios. In this embodiment, the target antennas include two of the multiple antennas 10. For example, in this embodiment, the target antennas corresponding to AP0 are the first antenna 110 (Ant0 in the table) and the second antenna 120 (Ant1 in the figure); AP1 corresponds to the second antenna 120 (Ant1 in the table) and the third antenna 130 (Ant2 in the table); APn corresponds to the second antenna 120 (Ant1 in the table) and the fourth antenna 140 (Ant3 in the table).

[0041] If the first switching mode is selected as the target switching mode, the control chip 30 selects the target frequency band and the target antenna corresponding to the target scene as the second target antenna. For example, in Figure 8 In the case where the current frequency band supported by the plurality of antennas 10 is Figure 8 The operating frequency band is shown in the figure; and if the target scenario is the first scenario (AP0), then the control chip 30 selects the first antenna 110 (marked as Ant0 in the table) and the second antenna 120 (marked as Ant1 in the figure) as the second target antenna. If the target scenario is the second scenario (AP1), then the control chip 30 selects the second antenna 120 (marked as Ant1 in the table) and the third antenna 130 (marked as Ant2 in the table) as the second target antenna. If the target scenario is the (n+1)th scenario (marked as scenario n), then the control chip 30 selects the second antenna 120 (marked as Ant1 in the table) and the fourth antenna 140 (marked as Ant3 in the table) as the second target antenna.

[0042] In the electronic device 1 provided in this application embodiment, if the first switching mode is selected as the target switching mode, the control chip 30 selects the target frequency band and the target antenna corresponding to the target scene as the second target antenna. The target antenna is two of the plurality of antennas 10, and the transmission performance of the target antenna in the same operating frequency band and the same scene is superior to the transmission performance of any combination of the other two antennas 10. Therefore, the electronic device 1 provided in this application embodiment can quickly determine the target frequency band and the target antenna corresponding to the target scene according to the first switching mode; thereby improving the efficiency of the electronic device 1 in switching transmission antennas.

[0043] In one embodiment, if the second switching mode is selected as the target switching mode, in the current scenario, the control chip 30 obtains the reception performance parameters of each of the plurality of antennas 10 in the current scenario and current frequency band; the control chip 30 selects the antenna 10 with the best reception performance as the second target antenna.

[0044] Specifically, the control chip 30 acquires the reception performance parameters of the first target antenna in the current scene and current frequency band. Furthermore, the control chip 30 iterates through each of the plurality of antennas 10 except for the first target antenna, and obtains the reception performance parameters of each of the plurality of antennas 10 except for the first target antenna in the current scene and current frequency band. Therefore, the control chip 30 obtains the reception performance parameters of the MiG antenna 10 among the plurality of antennas 10 in the current scene and current frequency band; that is, the control chip 30 obtains multiple performance parameters. The control chip 30 selects the antenna 10 with the optimal reception performance parameters as the second target antenna based on these multiple performance parameters.

[0045] Typically, the reception performance parameters of antenna 10 as a receiving antenna are related to its transmission performance parameters as a transmitting antenna. For example, if the reception performance parameters of one of the plurality of antennas 10 as a receiving antenna are better than those of another, then the transmission performance parameters of that antenna 10 as a transmitting antenna are also better. Therefore, when the antenna 10 with the best reception performance parameters is used as a transmitting antenna, its transmission performance is also highly likely to be optimal.

[0046] In one embodiment, the receiving performance parameters include, but are not limited to, one or more of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Signal-to-Interference Noise Ratio (SINR). RSRP refers to the power of the received reference signal, which reflects the signal strength and quality of the network. It measures the power of the reference signal received by electronic device 1 from the network device. A higher RSRP value indicates a stronger received signal and better network coverage. RSRQ refers to the received reference signal strength, which reflects the signal quality of the network. It measures the quality of the reference signal received by electronic device 1 from the network device. A higher RSRQ value indicates better received signal quality and better network communication quality. SINR is the ratio of signal strength to noise level, which also reflects the signal quality of the network. Similarly, a higher SINR value indicates better network signal quality and better network communication quality. For ease of understanding, the following embodiments of this application use RSRP as an example for illustration.

[0047] The second switching method is also called the antenna 10 blind switching method. For example, the plurality of antennas 10 includes a first antenna 110, a second antenna 120, a third antenna 130, and a fourth antenna 140. If the first target antenna is the first antenna 110 (identified as Ant0), the receiving performance parameter RSRP will be used as an example. In the current scenario, the receiving performance parameter of the first target antenna is RSRP0. Furthermore, the control chip 30 traverses each of the plurality of antennas 10 and obtains the receiving performance parameters of each of the plurality of antennas 10 except for the first target antenna in the current scenario and current frequency band. For example, the performance parameter of the second antenna 120 is RSRP1, the performance parameter of the third antenna 130 is RSRP2, and the performance parameter of the fourth antenna 140 is RSRP3. The control chip 30 compares the values ​​of RSRP0, RSRP1, RSRP2, and RSRP3 to determine the maximum value among RSRP0, RSRP1, RSRP2, and RSRP3. For example, if RSRP2 is the maximum, the control chip 30 selects the antenna 10 (i.e., the third antenna 130) with the best receiving performance parameters (i.e., RSRP2) as the second target antenna.

[0048] The electronic device 1 provided in this application embodiment, if the second switching mode is selected as the target switching mode, the control chip 30 obtains the receiving performance parameters of each of the plurality of antennas 10 in the current scene and current frequency band, and the control chip 30 selects the antenna 10 with the optimal receiving performance parameters as the second target antenna. The second target antenna is used as the transmitting antenna during the second time period. Therefore, the electronic device 1 provided in this application embodiment can improve the switching efficiency of the antennas 10 when the scene changes, and improve the transmitting performance in the current scene and current frequency band, thereby improving the user experience of using the electronic device 1.

[0049] Furthermore, in one embodiment, if the third switching mode is selected as the target switching mode, in the current scenario, the second target antenna is the same as the first target antenna, and the transmission performance of the first target antenna is better than the transmission performance of the other antennas 10 among the plurality of antennas 10.

[0050] In this embodiment, the third switching method can also be referred to as the fixed antenna method. In this embodiment, in the current scenario, the second target antenna is the same as the first target antenna, also referred to as keeping the first target antenna as the transmitting antenna, or not switching the switching antenna 10. The reason for keeping the first target antenna in the current scenario is that the transmission performance of the first target frequency band is better than the transmission performance of the other antennas 10 among the plurality of antennas 10.

[0051] In this embodiment, if the third switching method is selected as the target antenna, the first target frequency band will continue to be used as the transmitting antenna in the second time period under the current scenario. On the one hand, the transmission performance of using the first target antenna as the transmitting antenna can be maintained under the current scenario. On the other hand, there is no need to blindly switch to other antennas 10, thereby improving the efficiency of determining the second target antenna.

[0052] Please see Figure 9 , Figure 9 This is a radiation pattern for one-handed holding of an electronic device according to an embodiment of this application. In this embodiment, one-handed holding of the electronic device 1 refers to a scenario where the electronic device 1 is in portrait mode and held with one hand. The plurality of antennas 10 includes a first antenna 110, a second antenna 120, and a third antenna 130. If the current scenario is a one-handed holding scenario: if the radiation pattern coverage area of ​​the third antenna 130 in the current frequency band is greater than that of the first antenna 110 in the current frequency band, and if the radiation pattern coverage area of ​​the third antenna 130 in the current frequency band is greater than that of the second antenna 120 in the current frequency band, the control chip 30 selects the first switching mode as the target switching mode, and the second antenna 120 becomes the second target antenna.

[0053] exist Figure 9 It includes four directional diagrams, among which, Figure 9 The image marked Ant0 is the radiation pattern of the first antenna 110 in the current scene and current frequency band. Figure 9 The image marked Ant1 is the radiation pattern of the second antenna 120 in the current scene and frequency band; Figure 9 The image marked Ant2 shows the radiation pattern of the third antenna 130 in the current scene and frequency band. Figure 9 The antennas marked Ant0+1+2 are the first antenna 110, the second antenna 120, and the third antenna 130. This is the common radiation pattern of the three antennas 10 in the current scene and the current frequency band. Figure 9 The diagram shown is a two-dimensional radiation pattern, with Phi on the horizontal axis and Theta on the vertical axis. In each diagram, the points corresponding to the horizontal and vertical axes represent the gain. The yellower the color, the higher the gain and the better the performance; the bluer the color, the lower the gain and the worse the performance. Figure 9 All four directional patterns in the image have been blurred.

[0054] Depend on Figure 9 It is evident that the coverage of the first antenna 110 (Ant0) is poor, while the coverage of the second antenna 120 (Ant1) and the third antenna 130 (Ant2) is better. Although the third antenna 130 (Ant2) is not as effective as the second antenna 120 (Ant1) at certain angles, its coverage is wider. Therefore, given the current frequency band and the current scenario, the control chip 30 selects the first switching mode as the target switching mode and predefines the second antenna 120 as the target antenna for the current scenario and current frequency band. During the second time period, the second antenna 120 serves as the second target antenna.

[0055] The electronic device 1 provided in this application embodiment, wherein the control chip 30 selects the first switching mode as the target switching mode and the second antenna 120 is the second target antenna; enables the electronic device 1 to cover a large range of directions and ensures connection performance during the second time period.

[0056] Understandably, after the second time period, the control chip 30 performs antenna 10 switching detection again to determine whether to switch, thereby improving user experience and avoiding negative benefits caused by blind switching of antenna 10.

[0057] After the second time period, the scenario of the electronic device 1 or the performance of the multiple antennas 10 may change. Therefore, after the second time period, the control chip 30 performs antenna 10 switching detection again to determine whether to switch, thereby improving the user experience and avoiding negative benefits caused by blind switching of antennas 10.

[0058] Please see Figure 10 , Figure 10 This is a free-space radiation pattern of an electronic device provided in one embodiment of this application. In this embodiment, the plurality of antennas 10 include a first antenna 110, a second antenna 120, and a third antenna 130. If the current scenario is a free-space scenario: if the radiation pattern of the first antenna 110 covers the first half of the current frequency band, and the radiation pattern of the second antenna 120 covers the second half of the current frequency band, the control chip 30 selects the second switching mode as the target switching mode.

[0059] exist Figure 10 It includes four directional diagrams, among which, Figure 10 The image marked Ant0 is the radiation pattern of the first antenna 110 in the current scene and current frequency band. Figure 10 The image marked Ant1 is the radiation pattern of the second antenna 120 in the current scene and frequency band; Figure 10 The image marked Ant2 shows the radiation pattern of the third antenna 130 in the current scene and frequency band. Figure 10 The antennas marked Ant0+1+2 are the first antenna 110, the second antenna 120, and the third antenna 130. This is the common radiation pattern of the three antennas 10 in the current scene and the current frequency band. Figure 10 The diagram shown is a two-dimensional radiation pattern, with Phi on the horizontal axis and Theta on the vertical axis. In each diagram, the points corresponding to the horizontal and vertical axes represent the gain. The yellower the color, the higher the gain and the better the performance; the bluer the color, the lower the gain and the worse the performance. Figure 10 All four directional patterns in the image have been blurred.

[0060] Depend on Figure 10 As can be seen, the first antenna 110 (Ant0) covers the left half of the radiation pattern, and the second antenna 120 (Ant1) covers the right half of the radiation pattern. The areas covered by the first antenna 110 (Ant0) and the second antenna 120 (Ant1) each occupy half or approximately half. Therefore, in the current frequency band and the current scenario, the control chip 30 selects the second switching mode as the target switching mode for switching. Under different environments, the receiving performance parameters (such as RSRP) of the first antenna 110 (Ant0) and the second antenna 120 (Ant1) are compared, and the higher value is selected as the second target antenna. Thus, it can be seen that the control chip 30 of the electronic device 1 provided in this embodiment can switch the transmitting antenna to the antenna 10 with better performance.

[0061] Please see Figure 11 , Figure 11This is a free-space radiation pattern of an electronic device provided in one embodiment of this application. The plurality of antennas 10 include a first antenna 110, a second antenna 120, and a third antenna 130. If the current scenario is a two-handed holding scenario: if the first antenna 110 is the first target antenna during the first time period, the control chip 30 selects the third switching mode as the target switching mode, wherein the third switching mode is used to keep the first antenna 110 as the second target antenna, wherein the radiation pattern of the first antenna 110 has full coverage in the current frequency band, and the radiation pattern coverage of the first antenna 110 in the current frequency band is better than the radiation pattern coverage of the second antenna 120 in the current frequency band, and the radiation pattern coverage of the first antenna 110 in the current frequency band is better than the radiation pattern coverage of the third antenna 130 in the current frequency band.

[0062] exist Figure 11 It includes four directional diagrams, among which, Figure 11 The image marked Ant0 is the radiation pattern of the first antenna 110 in the current scene and current frequency band. Figure 11 The image marked Ant1 is the radiation pattern of the second antenna 120 in the current scene and frequency band; Figure 11 The image marked Ant2 shows the radiation pattern of the third antenna 130 in the current scene and frequency band. Figure 11 The antennas marked Ant0+1+2 are the first antenna 110, the second antenna 120, and the third antenna 130. This is the common radiation pattern of the three antennas 10 in the current scene and the current frequency band. Figure 11 The diagram shown is a two-dimensional radiation pattern, with Phi on the horizontal axis and Theta on the vertical axis. In each diagram, the points corresponding to the horizontal and vertical axes represent the gain. The yellower the color, the higher the gain and the better the performance; the bluer the color, the lower the gain and the worse the performance. Figure 11 All four directional patterns in the image have been blurred.

[0063] Depend on Figure 11 As can be seen, the first antenna 110 (Ant0) has relatively comprehensive coverage, while the second antenna 120 (Ant1) and the third antenna 130 (Ant2) have very poor coverage. Therefore, in the current scenario, the control chip 30 selects the third switching method as the target switching method and keeps the first antenna 110 (Ant0) fixed, without switching. This is because switching to any antenna 10 other than the first antenna 110 (Ant0) would result in switching to a less effective antenna 10. Therefore, keeping the first antenna 110 (Ant0) fixed is the best strategy.

[0064] Please see Figure 12 , Figure 12This diagram illustrates the target switching methods corresponding to various operating frequency bands and scenarios of an electronic device provided in one embodiment of this application. In this diagram, the left column represents the specific frequency bands of each operating frequency band, such as the B3 band, B5 band, and N41 band; the top row represents various scenarios, for example, labeled as the first scenario (AP0 in the table), the second scenario (AP1 in the table), the third scenario (AP2), and the fourth scenario (AP3), respectively. The intersection of the row and column represents the operating frequency band in the row and the target switching method corresponding to the scenario in the column.

[0065] It should be noted that, Figure 12 The diagram shows the target switching methods corresponding to each operating frequency band and each scenario of the electronic device 1 provided in one embodiment of this application. The switching methods corresponding to different operating frequency bands are unrelated. For example, in one embodiment, if the third switching method of the B3 frequency band changes to another switching method, the third switching method of the B5 frequency band may remain unchanged.

[0066] If all the antennas 10 support the B3 band, the target switching methods corresponding to each scenario are described in detail. Specifically, if the current scenario of the electronic device 1 is a free space scenario, the control chip 30 selects the third switching method as the target switching method. If the current scenario of the electronic device 1 is a one-handed holding scenario, the control chip 30 selects the second switching method as the target switching method. If the current scenario of the electronic device 1 is a left-head-and-hand scenario or a two-handed holding scenario, the control chip 30 selects the third switching method as the target switching method.

[0067] In this embodiment, the B3 frequency band has target switching methods for different scenarios. Therefore, the target switching method for the current scenario can be quickly determined based on the current frequency band and the current scenario.

[0068] If all the antennas 10 support the B5 band, the target switching methods corresponding to each scenario are described in detail. If the current scenario of the electronic device 1 is a free space scenario or a left-head-and-hand scenario, the control chip 30 selects the first switching method as the target switching method. If the current scenario of the electronic device 1 is a one-handed holding scenario, the control chip 30 selects the third switching method as the target switching method. If the current scenario of the electronic device 1 is a two-handed holding scenario, the control chip 30 selects the second switching method as the target switching method.

[0069] In this embodiment, the B5 band has target switching methods for different scenarios. Therefore, the target switching method for the current scenario can be quickly determined based on the current frequency band and the current scenario.

[0070] If all the antennas 10 support the N41 frequency band, the target switching methods corresponding to each scenario are described in detail. If the current scenario of the electronic device 1 is a free space scenario or a two-handed holding scenario, the control chip 30 selects the first switching method as the target switching method. If the current scenario of the electronic device 1 is a one-handed holding scenario, the control chip 30 selects the second switching method as the target switching method. If the current scenario of the electronic device 1 is a left-head-and-hand scenario, the control chip 30 selects the first switching method as the target switching method.

[0071] In this embodiment, the N41 frequency band has target switching methods for different scenarios. Therefore, the target switching method for the current scenario can be quickly determined based on the current frequency band and the current scenario.

[0072] In summary, the electronic device 1 provided in this application allows the control chip 30 to select a target switching mode from multiple switching methods based on the current frequency band supported by the plurality of antennas 10 in the electronic device 1 and the current scenario in which the electronic device 1 is located. Using the target switching mode, a second target antenna is determined from the plurality of antennas 10, and this second target antenna is used as the transmitting antenna during a second time period. The second target antenna, as the transmitting antenna (also called the uplink antenna), exhibits good transmission performance. Therefore, the electronic device 1 provided in this application, by selecting different switching modes for different scenarios, can ensure that the uplink antenna is in the optimal state as much as possible. This avoids poor antenna pattern coverage when only a fixed antenna 10 is used as the uplink antenna in certain scenarios, and also avoids the unintelligent drawback of using only the third switching mode with a fixed antenna 10 as the uplink antenna in certain scenarios. It also prevents high overhead from transitional switching when only the second switching mode is used in certain scenarios, thereby improving the efficiency of antenna 10 switching.

[0073] In one embodiment, the multiple switching methods of the electronic device 1 provided in this application include a first switching method, a second switching method, and a third switching method. The strategies for determining the second target antenna are all different in the first switching method, the second switching method, and the third switching method. The first switching method is also called the pre-selection of antenna 10 switching method, the second switching method is also called the antenna 10 blind switching method, and the third switching method is also called the antenna 10 fixed method. The electronic device 1 provided in this embodiment utilizes scene recognition to customize the switching scheme. The control chip 30 selects one switching method as the target switching method from multiple switching methods based on the current frequency band supported by the multiple antennas 10 and the current scene, thereby achieving the technical effect of improving the switching efficiency of the antennas 10 and improving the user experience when the scene changes.

[0074] The electronic device 1 provided in this application is not limited to the scenarios described above, that is, it is not limited to free space, left-handed holding, two-handed holding, etc.; nor is it limited to the frequency bands described above. The electronic device 1 provided in this application can expand the scenarios. For example, the scenarios recognized by the electronic device 1 provided in this application can be expanded to include left-handed holding, left-handed holding, two-handed holding, pocket mode, and other scenarios. The frequency bands supported by the plurality of antennas 10 of the electronic device 1 may also include Long Term Evolution (LTE), New Radio (NR), or Wireless Fidelity (WiFi).

[0075] The first switching mode of the electronic device 1 provided in this application embodiment, through scene recognition and pre-set antenna 10 or antenna 10 combination, can protect the user when the scene of the electronic device 1 (also known as user equipment UE) changes, so that the transmitting antenna (i.e., the uplink transmission antenna 10) is in the antenna 10 with the best performance or in the antenna 10 combination with the best performance, thereby improving the directional coverage of the antenna 10.

[0076] Furthermore, please refer again. Figure 1 and Figure 2 In one embodiment, the electronic device 1 includes a mid-frame 60, a display screen 70, and a back cover 80. In this embodiment, the mid-frame 60 includes a mid-plate 610 and a frame portion 620. The frame portion 620 surrounds the periphery of the mid-plate 610. In this embodiment, the example is illustrated by stating that each radiator of the plurality of antennas 10 is located in the frame portion 620. It should be understood that this should not be construed as a limitation of the embodiments of this application.

[0077] The display screen 70 is a component in the electronic device 1 that performs a display function. The middle frame 60 supports the display screen 70, and the display screen 70 is disposed on one side of the middle frame 60. The back cover 80 is disposed on the other side of the middle frame 60. In other words, the back cover 80 and the display screen 70 are respectively disposed on opposite sides of the middle frame 60.
