Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to a flexible screen terminal, an antenna adjustment method, and a storage medium. Background Technology
[0002] With the rapid development of flexible screen technology, various manufacturers have developed mobile phones and wearable devices equipped with flexible screens. Flexible screens are not only thinner and lighter in size, but also consume less power than traditional screens. Using flexible screens helps improve the battery life of terminal devices. At the same time, based on the bendable and flexible characteristics of flexible screens, their durability is also much higher than that of traditional screens, reducing the probability of accidental damage to terminal devices. Based on this, foldable screen phones equipped with flexible screens have also entered the market on a large scale. Foldable screen phones can bend 360 degrees, and even twist, which is equivalent to doubling the screen size of a traditional mobile phone, effectively improving the user's experience in office work, communication, and entertainment.
[0003] However, with the development of 5G technology, flexible screens need to support a very wide range of frequency bands, placing extremely high demands on antenna communication performance. But the positions of the antennas in a flexible screen terminal are fixed, and the configuration of the antenna communication performance is based solely on the fully unfolded and / or fully closed state of the flexible screen terminal. Therefore, during the folding process, the orthogonality of the antennas changes, resulting in low antenna efficiency. Consequently, the terminal's communication performance, such as Over-the-Air (OTA) technology performance and data throughput, is significantly reduced, failing to meet user service needs. Summary of the Invention
[0004] The main objective of this application is to provide a flexible screen terminal, an antenna adjustment method, and a storage medium. The aim is to at least ensure that the flexible screen terminal's antenna is in optimal working condition, improve antenna efficiency, thereby enhancing the communication performance of the flexible screen terminal and better meeting users' business needs.
[0005] To achieve the above objectives, this application provides a flexible screen terminal, including: a first detection module, a second detection module, a control module, an adjustment module, and an antenna; the first detection module is used to detect and collect the communication performance parameters of the terminal and send the parameters to the control module; the control module is used to control the second detection module to detect and collect the folding angle of the terminal when it is determined that the received parameters do not meet preset service requirements; the second detection module is also used to send the folding angle to the control module; the control module is also used to determine the target working state of the antenna based on the folding angle and in combination with a preset correspondence between the folding angle and the optimal working state of the antenna; the adjustment module is used to adjust the working state of the antenna to the target working state.
[0006] To achieve the above objectives, this application also provides an antenna adjustment method, comprising: collecting communication performance parameters of the terminal; when it is determined that the parameters do not meet preset service requirements, collecting the folding angle of the terminal; based on the folding angle and in combination with a preset correspondence between the folding angle and the optimal working state of the antenna, determining the target working state of the antenna; and adjusting the working state of the antenna to the target working state.
[0007] To achieve the above objectives, embodiments of this application also provide a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the antenna adjustment method described above.
[0008] This application proposes a flexible screen terminal, antenna adjustment method, and storage medium. The flexible screen terminal includes a first detection module, a second detection module, a control module, an adjustment module, and an antenna. The first detection module detects and collects the communication performance parameters of the terminal and sends the parameters to the control module. The control module controls the second detection module to detect and collect the folding angle of the terminal when it determines that the received parameters do not meet preset service requirements. This allows for real-time monitoring of the terminal's communication performance and enables a rapid response to deterioration in terminal communication performance, protecting services from interruption. The second detection module also sends the folding angle to the control module. The control module further determines the target operating state of the antenna based on the folding angle and a preset correspondence between the folding angle and the antenna's optimal operating state. The adjustment module adjusts the antenna's operating state to the target operating state. When the terminal's communication performance does not meet preset service requirements, the flexible screen terminal of this invention can determine the current folding angle and adjust the antenna's operating state to the operating state corresponding to the folding angle, i.e., the optimal operating state. This improves the antenna's operating efficiency, thereby enhancing the flexible screen terminal's OTA performance, increasing the terminal's service data throughput, and better meeting users' service needs.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this application to help readers better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.
[0020] One embodiment of the present invention relates to a flexible screen terminal. In specific implementations, the flexible screen terminal of the present invention can be a foldable screen phone, a foldable screen computer, a hinged screen phone, and various flexible screen wearable devices. A structural schematic diagram of the flexible screen terminal of this embodiment is shown below. Figure 1 As shown, the flexible screen terminal 10 of this embodiment may include, but is not limited to, the following modules and components: a first detection module 11, a control module 12, a second detection module 13, an adjustment module 14, and an antenna 15. The control module 12 is connected to the first detection module 11, the second detection module 13, and the adjustment module 14, respectively, and the adjustment module 14 is connected to the antenna 15.
[0021] In one example, the flexible screen terminal of this embodiment can be a foldable screen phone. The first detection module 11, control module 12, second detection module 13, adjustment module 14, and antenna 15 can be located below the screen of the foldable screen phone or on the main board of the foldable screen phone. The control module 12 is connected to the first detection module 11, the second detection module 13, and the adjustment module 14, respectively. The adjustment module 14 is also connected to the antenna 15. The first detection module 11, control module 12, second detection module 13, and adjustment module 14 can be integrated into a single antenna adjustment device or can be individually located on the flexible screen phone. Figure 2 This is a structural diagram of a foldable screen phone.
[0022] The first detection module 11 is used to detect and collect the communication performance parameters of the terminal, and send the parameters to the control module 12.
[0023] Specifically, the first detection module 11 can continuously detect and collect the communication performance parameters of the terminal, and after collecting the communication performance parameters of the terminal, send these communication performance parameters to the control module 12.
[0024] In a specific implementation, the first detection module can be based on the transceiver inside the terminal, including but not limited to the transceiver, the communication RF main chip, and several amplifiers.
[0025] In one example, the first detection module 11 can collect the terminal's communication performance parameters every preset time interval. The intermittent collection method can effectively save power resources.
[0026] In one example, the first detection module 11 can collect the terminal's communication performance parameters once after the terminal's folded state changes.
[0027] In one example, the communication performance parameters acquired by the first detection module 11 include the overall communication performance parameters of the terminal, which include any combination of the following: the terminal's transmit power, reference signal receiving power (RSPR), received signal strength indication (RSSI), signal noise ratio (SNR), rank of multiple-in multiple-out antenna (MIMO Rank), modulation and coding scheme (MCS), modulation order, modulation coefficients, throughput, and bit error rate, etc.
[0028] In another example, the communication performance parameters acquired by the first detection module 11 also include the communication performance parameters of each antenna of the terminal. The communication performance parameters of each antenna of the terminal include any combination of the following: the transmit power of each antenna, the reference signal received power value RSPR of each antenna, the received signal strength indication value RSSI of each antenna, and the channel sounding reference signal (SRS) value of each antenna path, etc.
[0029] The control module 12 is used to control the second detection module 13 to detect and collect the folding angle of the terminal when it is determined that the received parameters do not meet the preset business requirements.
[0030] In a specific implementation, after the control module 12 obtains the communication performance parameters sent by the first detection module 11, it can determine whether the terminal's communication performance meets the preset service requirements based on the communication performance parameters. If the terminal's communication performance does not meet the preset service requirements, the control module 12 immediately sends a folding angle detection command to the second detection module 13, controlling the second detection module 13 to detect and collect the terminal's folding angle. This allows the terminal to react quickly when communication performance deteriorates, protecting the service from interruption. The preset service requirements can be set by those skilled in the art according to actual needs, and the embodiments of this invention do not specifically limit this.
[0031] In one example, if the terminal's communication performance can meet the needs of the current business, the flexible screen terminal will not adjust the antenna and will continue to maintain the normal operation of the first detection module 11, continuously or periodically detecting and collecting the terminal's communication performance parameters.
[0032] The second detection module 13 is used to detect and collect the folding angle of the terminal, and send the folding angle of the terminal to the control module 1212.
[0033] Specifically, after determining that the communication performance of the terminal cannot meet the preset service requirements, the control module 12 can send a folding angle detection command to the second detection module 13. After receiving the command, the second detection module 13 can detect and collect the folding angle of the terminal and send the folding angle to the control module 12.
[0034] In a specific implementation, the second detection module 13 can also detect and collect the folding state of the terminal, which can include: folded state, fully closed state and fully unfolded state.
[0035] In one example, the second detection module 13 may include an infrared sensor. After receiving an instruction, the second detection module 13 uses the infrared sensor to emit infrared rays to detect and collect the folding angle of the flexible screen terminal.
[0036] In one example, the second detection module 13 can acquire information from the baseband display page and, based on that information, detect and collect the folding angle of the flexible screen terminal.
[0037] In another example, a schematic diagram of the folding angle of the detection and acquisition terminal by the second detection module 13 can be shown as follows: Figure 3As shown, the flexible screen terminal also includes a first screen and a second screen. The first screen and the second screen can be two areas of a single, complete screen; the distinction between the first screen and the second screen is for ease of description. The second detection module 13 can emit a charge signal to the outside through the terminal's first screen. When the emitted charge signal encounters the second screen, some of the charge is reflected back. The second detection module 13 can determine the amount of charge reflected from the second screen to the first screen. Based on this amount of charge reflected from the second screen to the first screen, and combined with a preset correspondence between the amount of charge and the folding angle, the folding angle of the terminal is obtained. The preset correspondence between the amount of charge and the folding angle can be set by those skilled in the art based on extensive experimentation. By emitting and reflecting charge, the folding angle of the terminal can be accurately detected and acquired without the use of additional sensors.
[0038] Specifically, the flexible screen terminal in this embodiment also includes a Specific Absorption Rate (SAR) chip. The second detection module 13 is connected to the SAR chip, which is also connected to each antenna of the first screen and each antenna of the second screen. When detecting and acquiring the folding angle of the terminal, the second detection module 13 can continuously transmit charge signals to the outside through the charge bar circuit of the SAR chip via each antenna of the first screen. When the transmitted charge signals encounter each antenna of the second screen, some of the charge is reflected back. The second detection module 13 collects the charge reflected back from each antenna of the second screen through the sensing circuit of the SAR chip, stores it in a register, and determines the amount of charge reflected from each antenna of the second screen to each antenna of the first screen after analog-to-digital conversion. Based on the amount of charge reflected to each antenna of the first screen and combined with a preset correspondence between the amount of charge and the folding angle, the second detection module 13 obtains the folding angle of the terminal. Multiple antennas transmit charge simultaneously, and multi-channel simultaneous multiplexing detection can further improve the accuracy of the acquired folding angle.
[0039] In one example, the SAR chip can also be connected to other metal coupling units of the terminal screen, and the second detection module 13 continuously transmits charge signals to the outside world through the charge bar circuit of the SAR chip via these metal coupling units.
[0040] In one example, the amount of reflected charge can be represented by a SAR value, which is inversely proportional to the distance and the folding angle, and directly proportional to the inductive projected area. The preset relationship between the amount of charge and the folding angle is shown in Table 1:
[0041] Folding angle (unit: °) Charge quantity (SAR value) (unit: W / kg) 0° 1.8W / kg 30° 1.6W / kg 60° 1.4W / kg 90° 1.2W / kg 120° 1.0W / kg 150° 0.8W / kg 180° 0.6W / kg
[0042] Table 1: Correspondence between preset charge quantity and folding angle
[0043] For example, if the second detection module 13 determines that the amount of charge reflected from the second screen to the first screen is 1.0W / kg, then the second detection module 13, based on the amount of charge reflected from the second screen to the first screen and combined with the preset correspondence between the amount of charge and the folding angle, determines that the folding angle of the terminal is 120° at this time.
[0044] The control module 12 is also used to determine the target working state of the antenna based on the folding angle and in combination with the preset folding angle and the correspondence between the optimal working state of the terminal's antenna and the folding angle.
[0045] Specifically, after receiving the folding angle of the terminal from the second detection module 13, the control module 12 can determine the target operating state of the antenna based on the folding angle and the preset correspondence between the folding angle and the optimal operating state of the terminal's antenna. Considering that the positions of each antenna of the flexible screen terminal are fixed, and the configuration of the communication performance of the flexible screen terminal antenna is only based on the fully unfolded or fully closed state of the flexible screen terminal, the orthogonality of the antenna of the flexible screen terminal will deteriorate during the folding process, and the working efficiency of the antenna will also decrease. Determining the target operating state of the antenna based on the folding angle, that is, the optimal working state of the antenna at that folding angle, can improve the working efficiency of the antenna of the flexible screen terminal, thereby improving the communication performance of the flexible screen terminal and better meeting the user's business needs.
[0046] In its implementation, the flexible screen terminal also includes a memory. The pre-defined correspondence between the folding angle and the optimal operating state of the terminal's antenna is obtained based on numerous simulation experiments and can be pre-stored in the flexible screen terminal's memory as an algorithm. After receiving the folding angle from the terminal, the control module 12 can call the pre-stored algorithm to determine the target operating state of the antenna.
[0047] The adjustment module 14 is used to adjust the working state of the antenna 15 to the target working state.
[0048] In the specific implementation, the adjustment module 14 is connected to N antennas of the terminal, where N is an integer greater than 0. The working state of the antennas can be the number of working antennas and / or the combination of working antennas. The control module 12 is used to determine M target antennas from the N antennas based on the folding angle and in combination with the preset correspondence between the folding angle and the target antenna, where M is an integer greater than 0 and less than N. The adjustment module 14 is used to turn on the M target antennas and turn off the antennas other than the M target antennas. Considering that the antenna layout of the relevant 5G flexible screen terminal is fixed and single, and the relevant antenna combination is configured based on the fully unfolded state and / or fully closed state of the flexible screen terminal, when the folding angle of the terminal is arbitrary, the isolation and orthogonality characteristics of the traditional antenna combination cannot meet the service requirements. In this embodiment, the flexible screen terminal calls different antenna combinations at different folding angles, thereby ensuring the best isolation between the antennas in the antenna combination, the best orthogonality performance, and the strongest total antenna gain, further improving the working efficiency of the antennas of the flexible screen terminal, thereby further improving the communication performance of the flexible screen terminal.
[0049] In one example, the adjustment module 14 can be implemented based on the array switches of each antenna.
[0050] In one example, the preset correspondence between the folding angle and the target antenna is obtained based on a large number of simulation experiments, and it can be pre-stored in the memory of the flexible screen terminal in the form of an algorithm. After receiving the folding angle from the terminal, the control module 12 can call the pre-stored algorithm to determine M target antennas from N antennas.
[0051] For example: the terminal is equipped with 7 antennas, and the layout of the 7 antennas can be as follows: Figure 4 As shown, antennas 1, 2, 3, and 4 are traditional 4x4 MIMO antennas; antennas 5 and 6 are newly added auxiliary antennas capable of operating in the 5G band; and antenna 7 is a modified LTE antenna capable of operating in the 5G band. The correspondence between the preset folding angle and the target antenna is shown in Table 2.
[0052]
[0053]
[0054] Table 2: Correspondence between preset folding angles and target antennas
[0055] When the second detection module 13 detects that the folding angle of the terminal is 150°, the control module 12 determines the target antennas as antenna 1, antenna 2, antenna 4, and antenna 5 based on the folding angle of the terminal and the preset correspondence between the folding angle and the target antennas. The adjustment module 14 turns on antennas 1, 2, 4, and 5, and turns off antennas 3, 6, and 7.
[0056] In one example, after the adjustment module 14 adjusts the antenna's operating state to the target operating state, the first detection module 11 can continue to detect and acquire the terminal's communication performance parameters and send the parameters to the control module 12. The control module 12 continuously judges whether the terminal's communication performance meets the current service requirements. If not, it continues to adjust the antenna's operating state until the terminal's communication performance meets the current service requirements.
[0057] The flexible screen terminal of this embodiment includes a first detection module, a second detection module, a control module, an adjustment module, and an antenna. The first detection module is used to detect and collect the communication performance parameters of the terminal and send the parameters to the control module. The control module is used to control the second detection module to detect and collect the folding angle of the terminal when it is determined that the received parameters do not meet the preset service requirements. This allows for real-time monitoring of the terminal's communication performance and enables a rapid response to deterioration in terminal communication performance, protecting services from interruption. The second detection module is also used to send the folding angle to the control module. The control module is also used to determine the target operating state of the antenna based on the folding angle and a preset correspondence between the folding angle and the optimal operating state of the antenna. The adjustment module is used to adjust the operating state of the antenna to the target operating state. When the terminal's communication performance does not meet the preset service requirements, the flexible screen terminal of this invention can determine the current folding angle and adjust the antenna's operating state to the operating state corresponding to the folding angle, i.e., the optimal operating state. This can improve the antenna's operating efficiency, thereby improving the OTA performance of the flexible screen terminal, increasing the terminal's service data throughput, and better meeting the user's service needs.
[0058] Furthermore, in order to highlight the innovative aspects of this invention, this embodiment does not include modules that are not closely related to solving the technical problems proposed by this invention, but this does not mean that there are no other modules in this embodiment.
[0059] Another embodiment of the present invention relates to a flexible screen terminal. A schematic diagram of the structure of the flexible screen terminal in this embodiment is shown below. Figure 5 As shown, the flexible screen terminal 10 in this embodiment includes:
[0060] The system comprises a first detection module 11, a control module 12, a second detection module 13, an adjustment module 14, an antenna 251 for the first screen, an antenna 252 for the second screen, and an extension contact module 26. The control module 12 is connected to the first detection module 11, the second detection module 13, and the adjustment module 14. The adjustment module 14 is also connected to the antennas 251 and 252 for the first and second screens, respectively, and the extension contact module 26 is also connected to the antennas 251 and 252 for both screens. The extension contact module 26 includes P extension contacts for connecting the antennas 251 and 252 of the first and second screens, where P is a positive integer.
[0061] The control module 12 is also used to determine Q target extended contacts from P extended contacts based on the folding angle and in combination with the preset correspondence between the folding angle and the target extended contacts, where Q is an integer greater than 0 and less than P.
[0062] The adjustment module 14 is also used to activate Q target extension contacts to connect the antenna 251 of the first screen and the antenna 252 of the second screen.
[0063] In a specific implementation, the P extended contacts of the extended contact module 26 are respectively connected to the antenna 251 of the first screen and the antenna 252 of the second screen. After receiving the folding angle of the terminal sent by the second detection module 13, the control module 12 can determine Q target extended contacts from the P extended contacts based on the folding angle and in combination with the preset correspondence between the folding angle and the target extended contacts. The adjustment module 14 opens these Q target extended contacts and connects the antenna of the first screen and the antenna of the second screen. Considering that foldable screen terminals require folding, there are metal devices such as metal hinges, magnetic magnets, and metal decorative pieces between the first and second screens. The two screens are relatively independent, so the antenna clearance area is not a complete continuous radiator, the antenna clearance area is small, and the effective length of the antenna is short. The flexible screen terminal of this embodiment includes P extension contacts, and Q extension contacts can be opened according to the folding angle to connect the antenna 251 of the first screen and the antenna 252 of the second screen, so that the antenna clearance area of the terminal becomes a complete continuous radiator, increasing the effective length of the antenna and thus expanding the antenna clearance area of the terminal.
[0064] In one example, the adjustment module 14 can be implemented based on several single-pole double-throw switches controlling each extended contact in the extended contact module.
[0065] In one example, the pre-defined correspondence between the folding angle and the target extended contact points is obtained based on numerous simulation experiments, and can be pre-stored in the memory of the flexible screen terminal in the form of an algorithm. After receiving the folding angle from the terminal, the control module 12 can call the pre-stored algorithm to determine Q target extended contact points from P extended contact points.
[0066] In one example, the extended contact module 26 includes six extended contacts: extended contact 1, extended contact 2, extended contact 3, extended contact 4, extended contact 5, and extended contact 6. The positional arrangement of these six extended contacts can be as follows: Figure 7 As shown, if the control module 12 determines that the extended contact 3 and the extended contact 4 are the target extended contact points, then the adjustment module 14 will activate the extended contact 3 and the extended contact 4 to connect the antenna of the first screen and the antenna of the second screen.
[0067] In one example, the schematic diagram of the antenna after connection via the extended contact can be as follows: Figure 7 As shown, the antenna 251 of the first screen is connected to the antenna 252 of the second screen, and the clearance area of the antenna forms a complete continuous radiator.
[0068] In this embodiment, the terminal includes a first screen and a second screen. The terminal also includes an extended contact module, which includes P extended contacts for connecting the antennas of the first screen and the second screen, where P is an integer greater than 0. The control module is further configured to determine Q target extended contacts from the P extended contacts based on the folding angle and a preset correspondence between the folding angle and the target extended contacts, where Q is an integer greater than 0 and less than P. The adjustment module is further configured to activate the Q target extended contacts, connecting the antennas of the first screen and the second screen. Considering that the two screens of the flexible screen terminal are relatively independent, the antenna clearance area is not a complete continuous radiator, the antenna clearance area is small, and the effective length of the antenna is short, the flexible screen terminal in this embodiment also includes P extended contacts. Q target extended contacts can be activated according to the folding angle to connect the antennas of the first screen and the second screen, thereby making the antenna clearance area of the terminal a complete continuous radiator, increasing the effective length of the antenna, and thus expanding the antenna clearance area of the terminal.
[0069] Furthermore, in order to highlight the innovative aspects of this invention, this embodiment does not include modules that are not closely related to solving the technical problems proposed by this invention, but this does not mean that there are no other modules in this embodiment.
[0070] Another embodiment of the present invention relates to a flexible screen terminal. A schematic diagram of the structure of the flexible screen terminal in this embodiment is shown below. Figure 8 As shown, the flexible screen terminal 10 in this embodiment includes:
[0071] The system comprises a first detection module 11, a control module 12, a second detection module 13, an adjustment module 14, an antenna 15, and a stretchable flexible antenna 37. The control module 12 is connected to the first detection module 11, the second detection module 13, and the adjustment module 14. The adjustment module 14 is also connected to the antenna 15.
[0072] The layout diagram of the flexible antenna 37 in this embodiment can be seen as follows: Figure 9 As shown, the flexible antenna 37 is connected to the first screen and the second screen of the terminal respectively, and the first screen and the second screen are rotatably connected by a connecting device.
[0073] The control module 12 is used to determine the optimal resonant frequency of the flexible antenna 37, and, in conjunction with the preset correspondence between the optimal resonant frequency and the folding angle, to determine the target folding angle corresponding to when the flexible antenna 37 operates at the optimal resonant frequency. The adjustment module 14 is also used to drive the connection device between the first screen and the second screen to rotate the terminal to the target folding angle.
[0074] Specifically, the control module 12 can determine the optimal resonant frequency of the flexible antenna 37 based on the current operating frequency band of the terminal, and, combined with the preset correspondence between the optimal resonant frequency and the folding angle, determine the target folding angle corresponding to the flexible antenna 37 operating at the optimal resonant frequency. The adjustment module 14 can drive the connection device between the first screen and the second screen according to the target folding angle, rotating the terminal to the target folding angle, thereby increasing the electrical length of the flexible antenna 37, making the flexible antenna 37 operate at the optimal resonant frequency, and further improving the communication performance of the flexible screen terminal.
[0075] In one example, the adjustment module 14 can be implemented based on an antenna tuning and matching chip.
[0076] In one example, the connecting device can be a driveable motor.
[0077] In one example, the pre-defined correspondence between the optimal resonant frequency and the folding angle is obtained based on numerous simulation experiments, and can be pre-stored in the memory of the flexible screen terminal in the form of an algorithm. After receiving the folding angle from the terminal, the control module 12 can call the pre-stored algorithm to determine the target folding angle corresponding to when the flexible antenna 37 operates at the optimal resonant frequency.
[0078] In one example, the adjustment module 14 can also display the target adjustment angle on the terminal's first and / or second screens, instructing the user to rotate the terminal to the target folding angle. This embodiment allows the user to manually adjust the terminal's folding angle, which can improve the user's interactivity with the terminal.
[0079] In this embodiment, the terminal further includes a first screen and a second screen, which are rotatably connected via a connecting device. The terminal also includes a stretchable flexible antenna, which is connected to both the first and second screens. The control module 12 is further configured to determine the optimal resonant frequency of the flexible antenna and, based on a preset correspondence between the optimal resonant frequency and the folding angle, determine the target folding angle corresponding to the flexible antenna operating at the optimal resonant frequency. The adjustment module is further configured to drive the connecting device to rotate the terminal to the target folding angle, thereby increasing the electrical length of the flexible antenna, enabling it to operate at the optimal resonant frequency, and further improving the terminal's communication performance.
[0080] Furthermore, in order to highlight the innovative aspects of this invention, this embodiment does not include modules that are not closely related to solving the technical problems proposed by this invention, but this does not mean that there are no other modules in this embodiment.
[0081] Another embodiment of the present invention relates to an antenna adjustment method. The implementation details of the antenna adjustment method of this embodiment are described below. The following content is only for ease of understanding and is not essential for implementing this solution.
