[0038] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0039] In order to better understand the solutions of the embodiments of the present application, the relevant terms and concepts that may be involved in the embodiments of the present application are first introduced below.

[0040] 1. Equivalent Isotropically Radiated Power (EIRP)

[0041] EIRP is an indicator that measures the radiation capability of an antenna in a specific direction. It indicates how much power an ideal omnidirectional antenna (isotropic antenna) needs to input to achieve the same radiation intensity in the same direction as the actual antenna.

[0042] The calculation formula is: EIRP = Pt × Gt, where Pt is the output power of the transmitter (W or dBm) and Gt is the antenna gain (linear value or dBi). If the feeder loss (L) is taken into account, the formula is corrected to: EIRP = Pt × Gt / L. EIRP has a wide range of applications in wireless communication systems, such as wireless communication system design, spectrum management and interference analysis, and compliance testing of wireless devices (Wi-Fi, Bluetooth, 5G). By reasonably configuring and adjusting parameters such as transmit power and antenna gain, the EIRP value can be optimized, thereby improving the performance and coverage of the communication system.

[0043] The standard value of EIRP varies depending on the device type, operating frequency band, and regulatory requirements of the country or region. For example, in the 2.4GHz band, EIRP is limited to 20dBm in some countries or regions and to 36dBm in others.

[0044] 2. Power Spectral Density (PSD)

[0045] PSD is a key parameter to measure the energy distribution of a signal in the frequency domain. It is expressed in W / Hz or dBm / Hz, specifically as the signal power within a unit frequency bandwidth. PSD describes how the signal power fluctuates with frequency changes, thus intuitively reflecting the energy distribution characteristics of the signal in the frequency domain.

[0046] The main purpose of PSD compliance testing is to verify whether the power spectrum density of radiation or conduction of a device or system meets the requirements of relevant regulations or standards during actual operation. By optimizing antenna design, reasonably configuring and adjusting parameters such as transmit power and antenna gain, the PSD value can be optimized, thereby improving the performance and coverage of the communication system.

[0047] The standard value of PSD varies depending on the device type, operating frequency band, and regulatory requirements of the country or region. For example, in the 2.4GHz frequency band, PSD is limited to 8dBm / Hz in some countries or regions and to 10dBm / Hz in other countries or regions.

[0048] 3. Specific Absorption Rate (SAR)

[0049] SAR can also be called the specific absorption rate of electromagnetic waves. SAR is defined as the electromagnetic power absorbed or consumed by a unit mass of human tissue. For example, the SAR value can be expressed in units of W / kg (watts per kilogram) or mW / 10g (milliwatts per 10 grams), that is, the electromagnetic power absorbed per kilogram of human tissue or the electromagnetic power absorbed per ten grams of human tissue. The larger the SAR value, the greater the impact of the terminal device's radiation on the human body, and vice versa.

[0050] The main purpose of SAR compliance testing is to ensure that the electromagnetic waves radiated by wireless devices during normal use will not cause adverse effects on human health. Through testing, the electromagnetic radiation safety of the device can be evaluated and ensured to comply with the requirements of relevant regulations or standards. The size of the SAR value is closely related to the transmit power of the terminal device. In order to make the SAR value compliant, the current solution to reduce the SAR value is usually to reduce the transmit power by a fixed power backoff amount.

[0051] 4. Antenna tuning

[0052] Antenna tuning refers to adjusting the physical parameters (such as length, position) and electronic parameters (such as capacitance and inductance) of the antenna to match its impedance at a specific frequency with the impedance of the transmission line or radio equipment, thereby maximizing signal transmission efficiency and minimizing power reflection. The efficiency of antenna radiation energy is often affected by the antenna tuning state. When the terminal device operates in different frequency bands, the software can send different tuning parameters to the tuner to match the input impedance of the antenna with the characteristic impedance of the feeder.

[0053] An antenna parameter configuration method provided in an embodiment of the present application is applicable to terminal devices using one or more of the following communication technologies: Bluetooth (BT) communication technology, global positioning system (GPS) communication technology, wireless fidelity (Wi-Fi) communication technology, global system for mobile communications (GSM) communication technology, wideband code division multiple access (WCDMA) communication technology, long term evolution (LTE) communication technology, 5G communication technology, SUB-6G communication technology and other future communication technologies, etc. The terminal devices described in the embodiments of the present application may include mobile phones, cameras, tablet computers, laptop computers, PDAs, wearable devices, augmented reality (AR) / virtual reality (VR) devices, etc.

[0054] An embodiment of the present application provides an antenna parameter configuration method. By using scenario detection, a maximum transmission power matching the current usage scenario is configured for the antenna. On the premise of ensuring compliance with relevant compliance tests, the maximum transmission power configuration of the antenna is optimized, effectively solving the problem of insufficient power in specific usage scenarios, which is beneficial to improving the overall performance of the antenna, thereby improving the communication quality.

[0055] It should be noted that the terminal device uses one or more communication technologies to achieve information transmission, each of which relies on at least one antenna to work, and these communication technologies can also share the same set of antennas to complete communication tasks. The antenna parameter configuration method provided in the embodiment of the present application can realize flexible configuration of antenna parameters for one or more specific communication technologies in the terminal device.

[0056] Figure 1 FIG. 1 is a schematic diagram of a first process of the antenna parameter configuration method in an embodiment of the present application. Figure 1 As shown, the method may specifically include:

[0057] Step 101: Obtaining operation information of the terminal device;

[0058] Step 102: Determine the current usage scenario of the terminal device based on the operation information of the terminal device;

[0059] In some embodiments, determining a current usage scenario of the terminal device based on operating information of the terminal device includes: determining whether the current usage scenario of the terminal device is a usage scenario in which at least one antenna is blocked based on the operating information of the terminal device.

[0060] In some embodiments, the antenna to be configured includes a first antenna, and the usage scenarios of the terminal device include: a usage scenario in which the first antenna is blocked and a usage scenario in which the first antenna is not blocked.

[0061] In some embodiments, the antenna to be configured includes a first antenna and a second antenna, and the working frequency bands of the first antenna and the second antenna are the same or similar; and the usage scenario of the terminal device includes at least one of the following:

[0062] A first usage scenario in which a first antenna is blocked and a second antenna is not blocked;

[0063] A second usage scenario in which both the first antenna and the second antenna are blocked;

[0064] A third usage scenario in which both the first antenna and the second antenna are not blocked.

[0065] In some embodiments, the antenna to be configured includes more than two antennas, the operating frequency bands of the more than two antennas are the same or similar, and the usage scenario of the terminal device includes at least one of the following: a usage scenario in which some antennas are blocked and some antennas are not blocked, a usage scenario in which all antennas are blocked, and a usage scenario in which all antennas are not blocked.

[0066] It should be noted that the antenna to be configured may be a group of antennas of a terminal device, the group of antennas including one or more antennas, used to implement information transmission of a communication technology. Exemplarily, the antenna to be configured includes but is not limited to: WiFi antenna, BT antenna, mobile communication antenna, GPS antenna, etc.

[0067] Objects that block the antenna include, but are not limited to, human body parts (such as hands, heads, etc.). Objects that block the antenna may also include other obstacles that reduce the antenna gain.

[0068] The operation information is used to identify the current usage scenario of the terminal device. Exemplarily, the operation information of the terminal device includes at least one of the following: antenna impedance, sensor data, and currently running application.

[0069] Antenna impedance refers to the ratio of voltage to current at the antenna input. The size and phase characteristics of antenna impedance have an important impact on the performance of the antenna, including the radiation efficiency, bandwidth, and directivity of the antenna. Due to the particularity of the human body, when a part of the human body (such as the hand, head, etc.) approaches or touches the antenna, it will change the electromagnetic environment of the antenna, resulting in a significant impedance difference from free space. In addition, there are also significant impedance differences due to different ways of contact between the human body and the terminal device.

[0070] Exemplarily, the parameter characterizing the antenna impedance may be a reflection coefficient.

[0071] The reflection coefficient refers to the ratio of the amplitude of the reflected wave to the amplitude of the incident wave when the signal encounters impedance mismatch on the transmission line. The reflection coefficient is a complex number that represents the amplitude ratio and phase difference between the reflected wave and the incident wave. It is usually defined as the ratio of the reflected voltage to the incident voltage, but at the power level, it can also be understood as the square root of the ratio of the reflected power to the incident power. It describes the degree of signal reflection on the transmission line and has an important impact on the signal transmission quality and system performance. When the input impedance of the antenna is completely matched with the characteristic impedance of the transmission line or the load impedance of the receiver, the reflection coefficient is equal to zero (ideal situation), indicating that no signal reflection occurs. Conversely, when the impedance is mismatched, the reflection coefficient is not zero, and the greater the impedance mismatch, the greater the reflection coefficient. In other words, the reflection coefficient can be used as a parameter to characterize the antenna impedance.

[0072] In some embodiments, antenna impedance detection is implemented by an impedance detection circuit to obtain the reflection coefficient of one or more antennas.

[0073] Figure 2 A schematic diagram of an antenna impedance detection circuit provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, taking the impedance detection of antenna 1 as an example, the incident power and reflected power are detected respectively through the directional coupler (CPL1) inside the power amplifier (PA) module on the transmitting path and the detection circuit in the receiving path, so as to obtain the reflection coefficient of antenna 1. The impedance detection of other antennas is based on the same method.

[0074] Sensor data includes data collected by one or more sensors on the terminal device, which sense and measure the motion information, posture information, usage environment information, etc. of the terminal device.

[0075] Exemplarily, the sensor includes but is not limited to an accelerometer, a gyroscope, a gravity sensor, and the like.

[0076] Currently running applications refer to applications or services that have been launched and are actively executing on the terminal device. The terminal device has multitasking capabilities, which means that it can run multiple such applications at the same time. More specifically, current applications refer to applications or services that are exchanging information with other terminal devices or network devices through their built-in antennas.

[0077] In some embodiments, based on the operating information of the terminal device, it is determined whether the current usage scenario of the terminal device is a usage scenario where at least one antenna is blocked, including: the change characteristics of the antenna impedance match the preset change characteristics, the sensor data characterizes that the terminal device is working in a first posture, and the currently running application belongs to one or more of the application whitelists, and the current usage scenario is determined to be a usage scenario where at least one antenna is blocked.

[0078] Exemplarily, the change characteristic of the first antenna impedance matches the preset change characteristic, and the first antenna is determined to be blocked, otherwise, the first antenna is determined to be unblocked. For example, when the change amount of the first antenna impedance is greater than the preset change amount, the first antenna is determined to be blocked, otherwise, the first antenna is determined to be unblocked. For another example, the first antenna impedance is input into a pre-trained scene recognition model to determine whether the change characteristic of the first antenna impedance matches the preset change characteristic.

[0079] Exemplarily, the sensor data indicates that the terminal device is operating in a first posture, the currently running application belongs to an application whitelist, and it is determined that the current usage scenario is a usage scenario in which at least one antenna is blocked.

[0080] The application whitelist includes one or more applications running in the first posture. Exemplarily, the first posture is the horizontal screen state, and the application whitelist includes applications running in the horizontal screen state, such as games, audio and video, etc. The first posture is the vertical screen state, and the application whitelist includes applications running in the vertical screen state, such as calls, walkie-talkies, satellite communications, web browsing, social networking, etc.

[0081] Step 103: Based on the current usage scenario of the terminal device, configure the maximum transmit power of the antenna.

[0082] The maximum transmit power of an antenna is also called the maximum allowable transmit power. In wireless communications, the maximum transmit power of an antenna refers to the maximum power that the antenna can radiate under specific conditions. This power value is usually limited by regulations, technical standards and safety requirements.

[0083] In some embodiments, based on the current usage scenario of the terminal device, the maximum transmission power of the antenna is configured, including: when the current usage scenario of the terminal device is a usage scenario where at least one antenna is blocked, increasing the maximum transmission power of the first target antenna.

[0084] In one example, the first target antenna includes an unobstructed antenna, and increasing the maximum transmit power of the first target antenna includes: increasing the maximum transmit power of the unobstructed antenna to a first transmit power.

[0085] It should be noted that when the terminal device includes at least two antennas, if it is detected that a part of the antenna of the terminal device is blocked, the transmission power of the other unblocked antenna is increased while ensuring compliance with relevant compliance tests, thereby realizing intelligent power allocation of at least two antennas. This is beneficial to maintaining or improving the overall performance of the antenna and avoiding the problem of communication quality degradation or even interruption due to antenna being blocked.

[0086] Exemplarily, the maximum transmit power of the blocked antenna is increased from the third transmit power or the fourth transmit power to the first transmit power, the third transmit power meets the compliance requirements of one or more indicators, the fourth transmit power is the maximum transmit power in the free space scenario, and the first transmit power is greater than the maximum transmit power of the antenna in the free space scenario and is less than or equal to the full power of the antenna.

[0087] In yet another example, the first target antenna includes a blocked antenna, and increasing the maximum transmit power of the target antenna includes: increasing the maximum transmit power of the blocked antenna to a second transmit power.

[0088] It should be noted that when the terminal device includes at least one antenna, if it is detected that one or more antennas of the terminal device are blocked, the transmission power of the blocked antenna is increased while ensuring compliance with relevant compliance tests. This maintains the reliability and stability of communication to a certain extent and avoids the problem of communication quality degradation or even interruption due to antenna blocking.

[0089] Exemplarily, the maximum transmit power of the blocked antenna is increased from the third transmit power or the fourth transmit power to the second transmit power. For example, the third transmit power meets the compliance requirements of one or more indicators, the fourth transmit power is the maximum transmit power in a free space scenario, and the second transmit power is the transmit power within the SAR compliance limit.

[0090] In another example, the first target antenna includes an unobstructed antenna and a blocked antenna, and increasing the maximum transmit power of the target antenna includes: increasing the maximum transmit power of the unobstructed antenna to a first transmit power; and increasing the maximum transmit power of the blocked antenna to a second transmit power.

[0091] It should be noted that when the terminal device includes at least two antennas, if it is detected that a part of the antenna of the terminal device is blocked, under the premise of ensuring compliance with relevant compliance tests, the transmission power of the other unblocked antenna is increased, and the transmission power of the blocked antenna is increased at the same time, to achieve intelligent power allocation of at least two antennas, which is beneficial to maintain or improve the overall performance of the antenna and avoid the problem of communication quality degradation or even interruption due to antenna being blocked.

[0092] In some embodiments, the method further includes: determining the maximum transmission power of the antenna based on the current usage scenario and parameter configuration information of the terminal device.

[0093] In some embodiments, the method further includes: determining parameter configuration information of the antenna based on the antenna type, wherein different antenna types correspond to different communication technologies, and the maximum transmit power configurations of different communication technologies may be different, and different parameter configuration information is constructed for different antenna types to adapt to the parameter configurations of different antenna types.

[0094] Exemplarily, the antenna types include, but are not limited to: WiFi antenna, BT antenna, mobile communication antenna, GPS antenna, etc.

[0095] In some embodiments, the method also includes: on the premise of meeting the compliance requirements of one or more indicators, determining the maximum transmission power when one or more antennas are not obstructed, and the maximum transmission power when one or more antennas are obstructed, so as to construct parameter configuration information, the parameter configuration information including the maximum transmission power corresponding to each antenna when it is not obstructed and when it is obstructed.

[0096] In some embodiments, the method may also include: obtaining the maximum transmission power when one or more antennas are not blocked, and the transmission power adjustment amount when one or more antennas are blocked, to construct parameter configuration information, the parameter configuration information including the maximum transmission power of each antenna when it is not blocked, and the power adjustment amount when it is blocked.

[0097] It should be noted that the parameter configuration information of the antenna is pre-set, and the parameter configuration information includes the maximum transmission power corresponding to each antenna in different usage scenarios, or the increase in the maximum transmission power compared to the default transmission power. According to the current usage scenario and parameter configuration information of the terminal device, the maximum transmission power of different antennas is determined and configured.

[0098] It should also be noted that the usage scenarios where the antenna is blocked can be further subdivided into at least two blocked usage scenarios according to the degree of antenna blockage. Each blocked usage scenario corresponds to a maximum transmission power or transmission power adjustment amount, thereby improving the accuracy of transmission power configuration.

[0099] In some embodiments, the method also includes: when the current usage scenario of the terminal device is a usage scenario in which at least one antenna is blocked, configuring the maximum transmission power of the second target antenna to be a third transmission power, the third transmission power meets the compliance requirements of one or more indicators, and the second target antenna is a blocked antenna.

[0100] To ensure that electronic products meet the electromagnetic radiation safety compliance requirements, it is essential to conduct compliance testing on electronic products. The compliance test related to the transmit power includes multiple key indicators, and the third transmit power can ensure that all indicators are compliant. The third transmit power can also be understood as the maximum transmit power when the antenna is not blocked.

[0101] Exemplarily, during the compliance test, the third transmit power is the minimum value of the transmit powers limited by multiple indicators, thereby ensuring that multiple indicators are compliant.

[0102] The key indicators of the antenna compliance test include the first indicator and the second indicator. To ensure that both the first indicator and the second indicator are compliant, the third transmit power is the minimum value of the transmit power 1 limited by the first indicator and the transmit power 2 limited by the second indicator.

[0103] Exemplarily, the key indicators of compliance testing include, but are not limited to: EIRP, PSD, SAR. The first indicator compliance may be EIRP or PSD, and the second indicator compliance may be SAR. In one example, when the current usage scenario of the terminal device is a usage scenario where at least one antenna is blocked, and the third transmit power is the transmit power within the PSD compliance limit, the maximum transmit power of the second target antenna remains unchanged at the third transmit power, that is, the maximum transmit power of the second target antenna when blocked and unblocked is the transmit power within the PSD compliance limit. In another example, when the current usage scenario of the terminal device is a usage scenario where at least one antenna is blocked, and the third transmit power is the transmit power within the SAR compliance limit, the maximum transmit power of the second target antenna is configured to be reduced to the transmit power within the SAR compliance limit to reduce electromagnetic radiation energy and reduce power consumption.

[0104] In some embodiments, when the current usage scenario of the terminal device is a usage scenario in which at least one antenna is blocked, the maximum transmission power of the first target antenna is increased from the third transmission power to the first transmission power or the second transmission power.

[0105] In some embodiments, the method further includes: when the current usage scenario of the terminal device is a usage scenario in which at least one antenna is blocked, impedance tuning is performed on the blocked antenna, and the performance of the blocked antenna is optimized through impedance tuning.

[0106] In some embodiments, configuring the maximum transmit power of the antenna based on the current usage scenario of the terminal device may include: when the current usage scenario of the terminal device is a usage scenario where the antenna is not obstructed, configuring the maximum transmit power of the antenna to be a fourth transmit power, the fourth transmit power being the maximum transmit power of the antenna in a free space scenario.

[0107] It should be noted that if the antenna is not blocked (which can be equivalent to or similar to a free space scenario), a fourth transmit power is configured for each antenna to maximize the transmit power while ensuring compliance with relevant compliance tests. In addition, the fourth transmit powers corresponding to different antennas are the same or different.

[0108] In one example, when the antenna is a first type antenna, the fourth transmit power is the transmit power limited by the first indicator. The first type antenna refers to an antenna whose transmit power in a free space scenario is limited by the first indicator. Therefore, in a free space scenario, the maximum transmit power of these antennas can be increased to the transmit power limited by the first indicator, maximizing the antenna transmit power. Exemplarily, the first type antenna includes but is not limited to a WiFi antenna, and the first indicator can be PSD or EIRP.

[0109] In another example, when the antenna is a second type antenna, the fourth transmit power is the full power of each antenna. The second type antenna refers to an antenna whose transmit power is not limited by relevant indicators in a free space scenario, but is only limited by full power. Therefore, in a free space scenario, the maximum transmit power of these antennas can be increased to full power at most. Exemplarily, the second type antenna includes but is not limited to a BT antenna.

[0110] In one example, if all antennas are not blocked, the maximum transmit power of each antenna may be increased to a fourth transmit power. In another example, if all antennas are not blocked, the maximum transmit power of each antenna may be kept unchanged at the fourth transmit power.

[0111] Exemplarily, if the bottleneck of the antenna transmit power is the transmit power limited by SAR compliance, that is, the third transmit power is the transmit power limited by SAR compliance, in the usage scenario where all antennas are not blocked, the maximum transmit power of each antenna can be increased to the fourth transmit power. If the bottleneck of the antenna transmit power is the transmit power limited by PSD or EIRP compliance, that is, the third transmit power is the transmit power limited by PSD compliance or EIRP compliance, in the usage scenario where all antennas are not blocked, the maximum transmit power of each antenna is kept unchanged at the fourth transmit power, and at this time, the fourth transmit power is the third transmit power.

[0112] By adopting the above technical solution, through the use of scenario detection, the antenna is configured with a maximum transmission power that matches the current usage scenario. On the premise of ensuring compliance with relevant compliance tests, the maximum transmission power configuration of the antenna is optimized, effectively solving the problem of insufficient power in specific usage scenarios, which is beneficial to improving the overall performance of the antenna and thus improving the communication quality.

[0113] Figure 3 Schematic diagram of a mobile phone antenna structure in an embodiment of the present application, such as Figure 3 As shown, the schematic diagram is specifically a rear view of a mobile phone antenna architecture, and multiple antennas are arranged around the metal middle frame of the mobile phone, which may specifically include: antenna ANT8 located in the middle of the left side, antenna ANT7 located at the top of the left side, antenna ANT9 located at the top near the left side, and antenna ANT12 located at the top near the middle. In other words, antenna ANT7, antenna ANT8, antenna ANT9 and antenna ANT12 are located at the upper left frame of the mobile phone.

[0114] Figure 4 Schematic diagram of a usage scenario of a mobile phone in an embodiment of the present application, such as Figure 4 As shown in the figure, when the mobile phone is held in landscape mode, the antennas ANT9 and ANT12 in the top area are directly blocked by the user's hands. This kind of blocking often leads to a certain degree of obstruction in signal transmission, because human hands, as conductors, may interfere with or absorb some wireless signals, thus affecting the communication quality and efficiency. Relatively speaking, the antennas ANT7 and ANT8 located on the side edges of the mobile phone are not blocked by human hands, and the antennas ANT7 and ANT8 can be approximately in free space. In this scenario, the use of antennas ANT7 and ANT8 can more effectively receive and transmit wireless signals.

[0115] Exemplarily, the functions of ANT7 include: primary receive (PRX) MIMO in the MH band, diversity reception (DRX) in the B41 band, DRX in the N14 band, the first link in the WiFi2.4G band, and the first link of Bluetooth (BT) communication.

[0116] The functions of ANT8 include: DRX in the N78 frequency band and the second link in the WiFi5G frequency band.

[0117] The functions of ANT9 include: Primary Receiver (PRX) in the N78 band and the first link in the WiFi5G band.

[0118] The functions of ANT12 include: L1 frequency band of Global Positioning System (GPS), second link under WiFi2.4G frequency band, and second link of Bluetooth (BT) communication.

[0119] against Figure 4 In this usage scenario, the antenna performance of antennas ANT9 and ANT12 is tested before and after being blocked by human hands. The test results are as follows: Figure 5-Figure 10 shown.

[0120] Figure 5 : is a comparative schematic diagram of the S parameter curves before and after ANT12 is blocked in the embodiment of the present application, Figure 6 This is a schematic diagram comparing the S parameter curves of ANT9 before and after being blocked in the embodiment of the present application. It can be seen that the antenna located at the top is affected by the human hand, and the antenna S parameter changes significantly.

[0121] Figure 7 : is a schematic diagram comparing the system efficiency curves before and after ANT12 is blocked in the embodiment of the present application, Figure 8 This is a schematic diagram comparing the system efficiency curves before and after ANT9 is blocked in the embodiment of the present application. It can be seen that due to the absorption characteristics of the human body, the cumulative efficiency of the system decreases by 6 to 10 dB.

[0122] Fig. 9 is the directional diagram of far-field radiation when ANT12 is not blocked in the embodiment of the present application, Fig.10 This is the directional diagram of the far-field radiation when ANT12 is blocked in the embodiment of the present application. It can be seen that the performance (system radiation efficiency, system cumulative radiation efficiency, gain) when ANT12 is not blocked is significantly better than the performance when ANT12 is blocked.

[0123] It can be seen that in the two-handed horizontal screen scenario, the top antennas ANT12 and ANT9 are blocked by human hands, while the side antennas ANT7 and ANT8 are not blocked. The S parameters of antennas ANT12 and ANT9 change significantly, and the antenna gain also decreases significantly. Due to the decrease in antenna gain, the transmit power is no longer a limiting bottleneck for antenna compliance requirements. Therefore, the transmit power of the antenna can be appropriately increased to optimize the antenna performance.

[0124] Based on the above-mentioned embodiments of the present application, a further example is given, in which the terminal device includes a first antenna and a second antenna, and the first antenna and the second antenna have the same operating frequency band.

[0125] like Fig.11 As shown, the method specifically includes:

[0126] Step 1101: Obtain operation information of the terminal device;

[0127] Step 1102: Determine a current usage scenario of the terminal device based on the operation information of the terminal device;

[0128] Step 1103: Whether the current usage scenario is a usage scenario where the first antenna is blocked, if yes, execute step 1104; if no, execute step 1105;

[0129] by Figure 3 For example, the first antenna is a WiFi2.4G antenna or a WiFi5G antenna located at the top, and the second antenna is a WiFi2.4G antenna or a WiFi5G antenna located on the side. The first antenna is blocked in the two-handed horizontal screen scenario. Exemplarily, the horizontal screen of the mobile phone is identified by the accelerometer / gyroscope, and the open applications are identified at the same time. For applications in the application whitelist (such as game APPs), both are met at the same time, that is, it is determined to be a two-handed horizontal screen scenario. Exemplarily, an antenna impedance detection circuit is added to identify whether the top antenna is held by a hand or blocked by the human body, that is, whether it is a two-handed horizontal screen scenario, so as to redistribute the power of the antenna.

[0130] by Figure 3 For example, the first antenna is a BT antenna located on the side, and the second antenna is a BT antenna located on the top. The first antenna is blocked in a one-handed holding scenario. Exemplarily, the vertical screen of the mobile phone is identified by the accelerometer / gyroscope, and the open applications are identified at the same time. For applications in the application whitelist (such as walkie-talkie APP), it is determined to be a one-handed holding scenario. Exemplarily, an antenna impedance detection circuit is added to identify whether the side antenna is held by a human hand or blocked by the human body, that is, whether it is a one-handed holding scenario, so as to redistribute the power of the antenna.

[0131] Step 1104: increasing the maximum transmission power of the second antenna that is not blocked;

[0132] Exemplarily, the maximum transmit power of the unobstructed second antenna is increased to a first transmit power, where the first transmit power is greater than the maximum transmit power of the second antenna in a free space scenario and less than the full power of the antenna.

[0133] In one example, the method may also include: when the current usage scenario is that the first antenna is blocked and the second antenna is not blocked, increasing the maximum transmit power of the blocked first antenna to the second transmit power; or, increasing the maximum transmit power of the unblocked second antenna to the first transmit power, and increasing the maximum transmit power of the blocked first antenna to the second transmit power; or, increasing the maximum transmit power of the unblocked second antenna to the first transmit power, and keeping the maximum transmit power of the blocked first antenna unchanged at a third transmit power, for example, the third transmit power is a transmit power within the PSD compliance or EIRP compliance limit; or, increasing the maximum transmit power of the unblocked second antenna to the first transmit power, and reducing the maximum transmit power of the unblocked first antenna to the third transmit power, for example, the third transmit power may be a transmit power within the SAR compliance limit.

[0134] In yet another example, when the current usage scenario is that the first antenna is blocked and the second antenna is blocked, the maximum transmission power of the first antenna and the second antenna is increased to the second transmission power.

[0135] In another example, when the current usage scenario is that the first antenna is blocked and the second antenna is blocked, the maximum transmit power of the first antenna and the second antenna remains unchanged at a third transmit power, for example, the third transmit power may be a transmit power within the PSD compliance or EIRP compliance limit; or is reduced to the third transmit power, for example, the third transmit power may be a transmit power within the SAR compliance limit.

[0136] Step 1105: Configure the maximum transmit power of the first antenna in a free space scenario.

[0137] In one example, when the first antenna is not blocked, the maximum transmit power of the first antenna is configured to be a fourth transmit power, where the fourth transmit power is the maximum transmit power of the first antenna in a free space scenario.

[0138] In another example, when the first antenna is not blocked and the second antenna is not blocked, that is, the first antenna and the second antenna are both in a free space scenario, the maximum transmit power of the first antenna is configured to a fourth transmit power, and the maximum transmit power of the second antenna is configured to a fourth transmit power, and the fourth transmit power is the maximum transmit power in the free space scenario.

[0139] Exemplarily, when the antenna is a first type antenna, the fourth transmit power is a transmit power limited by a first indicator. The first type antenna is an antenna whose transmit power is limited by a first indicator in a free space scenario.

[0140] When the antenna is a second type antenna, the fourth transmit power is the full power of the antenna. The second type antenna refers to an antenna whose transmit power is not limited by relevant indicators in a free space scenario, but is only limited by the full power.

[0141] The full power of an antenna usually refers to the state in which the antenna transmits signals at its maximum capacity or designed rated power under specific conditions. It more reflects the working ability of the antenna under ideal or designed conditions.

[0142] In one example, if Fig.12 As shown, when the first antenna is blocked, the method may further include step 1106: impedance tuning the blocked first antenna to adjust the antenna impedance. For example, closed-loop impedance adjustment, also known as adaptive tuning, is performed on the first antenna to adjust the antenna impedance in real time through a feedback signal monitored in real time.

[0143] Exemplarily, the first antenna and the second antenna are WiFi antennas. More specifically, the WiFi antenna may be a WiFi 2.4G antenna or a WiFi 5G antenna. The WiFi antenna structure may be as follows: Figure 3 As shown, the WiFi antenna structure can also be Fig.13 or Fig.14 shown.

[0144] Fig.15 Schematic diagram of the optional maximum transmission power of a WiFi antenna in an embodiment of the present application, such as Fig.15 As shown, the optional maximum transmit power of the WiFi antenna includes, from small to large, the transmit power limited by the PSD compliance limit, the transmit power limited by the SAR compliance limit, and the full power. Among them, the first transmit power is greater than the transmit power limited by the PSD compliance limit and is less than or equal to the full power, for example, the first transmit power is the transmit power limited by the SAR compliance limit or the full power. The second transmit power is greater than the transmit power limited by the PSD compliance limit and is less than or equal to the transmit power limited by the SAR compliance limit, for example, the first transmit power is the transmit power limited by the SAR compliance limit. The third transmit power is the transmit power limited by the PSD compliance limit. The fourth transmit power is less than or equal to the transmit power limited by the PSD compliance limit, for example, the fourth transmit power is the transmit power limited by the PSD compliance limit.

[0145] Fig.16 FIG. 1 is a schematic diagram of another optional maximum transmission power of a WiFi antenna in an embodiment of the present application, such as Fig.16As shown, the optional maximum transmit power of the WiFi antenna includes, from small to large, the transmit power limited by SAR compliance, the transmit power limited by PSD compliance, and full power. Among them, the first transmit power is greater than or equal to the transmit power limited by PSD compliance and less than or equal to full power, for example, the first power is full power. The third transmit power is the transmit power limited by SAR compliance. The fourth transmit power is greater than or equal to the transmit power limited by SAR compliance and less than or equal to the transmit power limited by PSD compliance, for example, the fourth transmit power is the transmit power limited by PSD compliance.

[0146] Exemplarily, the first antenna and the second antenna are BT antennas. The BT antenna structure can be as follows: Figure 3 shown.

[0147] Fig.17 This is a schematic diagram of an optional maximum transmit power of a BT antenna in an embodiment of the present application. The optional maximum transmit power of the BT antenna includes, from small to large, the transmit power limited by SAR compliance and full power. Among them, the first transmit power is greater than the transmit power limited by SAR compliance and less than or equal to full power, for example, the first transmit power is full power. The third transmit power is the transmit power limited by SAR compliance. The fourth transmit power is greater than or equal to the transmit power limited by SAR compliance and less than or equal to full power, for example, the fourth transmit power is the transmit power limited by SAR compliance or full power.

[0148] The power gain is as follows: the original maximum transmit power initial values ​​of the two antennas are the same. When antenna 1 is held fixedly, the maximum transmit power of antenna 2 can be increased by about 3dB while meeting the PSD compliance requirements. When the original maximum transmit power initial values ​​of the two antennas are different, for example, antenna 1>antenna 2, when antenna 1 is held fixedly, the maximum transmit power of antenna 2 is increased by less than 3dB. When antenna 2 is held fixedly, the maximum transmit power of antenna 1 can be increased by more than 3dB. Therefore, by using the scenario, while meeting the PSD compliance requirements, intelligent power allocation of WiFi / BT channels is implemented to improve user experience.

[0149] Fig.18 FIG. 1 is a flow chart of a method for configuring parameters of a WiFi / BT antenna in an embodiment of the present application. Fig.18 As shown, the method includes:

[0150] Step 1801: Obtaining operation information of the terminal device;

[0151] Step 1802: Determine the current usage scenario of the terminal device based on the operation information of the terminal device;

[0152] Step 1803: Determine whether the first antenna of WiFi / BT is blocked, if yes, execute step 1804 and step 1805; if no, execute step 1806;

[0153] Step 1804: increasing the maximum transmission power of the second antenna that is not blocked;

[0154] Step 1805: performing impedance tuning on the blocked first antenna;

[0155] Step 1806: For a WiFi antenna, configure the maximum transmit power of the first antenna to be the transmit power limited by the first indicator; for a BT antenna, configure the maximum transmit power of the first antenna to be full power.

[0156] In the free space scenario, for the WiFi antenna, the maximum transmit power of the first antenna is configured to be the fourth transmit power, and the fourth transmit power is the transmit power limited by the PSD compliance.

[0157] like Fig.15 As shown in the figure, if the transmit power limited by SAR compliance is greater than the transmit power limited by PSD compliance, when the antenna is blocked, the antenna gain will inevitably decrease, so that the transmit power limited by PSD compliance is no longer a bottleneck. Under the premise of ensuring PSD compliance, the maximum transmit power can be increased to the transmit power limited by SAR compliance. When the antenna is not blocked, the antenna gain returns to normal. At this time, the maximum transmit power of the first antenna needs to be reduced to the transmit power limited by PSD compliance to meet the PSD compliance requirements.

[0158] like Fig.16 As shown in the figure, if the transmit power limited by SAR compliance is less than the transmit power limited by PSD compliance, when the antenna is blocked, the transmit power limited by SAR compliance is still the power bottleneck of the WiFi antenna because the distance between the human body and the WiFi antenna is close; when the antenna is not blocked, the distance between the human body and the WiFi antenna is far, so the transmit power limited by SAR compliance is no longer the power bottleneck of the WiFi antenna. At this time, increasing the maximum transmit power of the first antenna to the transmit power limited by PSD compliance can not only meet the PSD compliance requirements, but also optimize the WiFi antenna performance.

[0159] In a free space scenario, for a BT antenna, a maximum transmit power of the first antenna is configured to be a fourth transmit power, and the fourth transmit power is full power.

[0160] like Fig.17 As shown in the figure, in the free space scenario, the transmit power limited by SAR compliance is no longer the power bottleneck of the BT antenna, and the maximum transmit power of the first antenna can be increased to full power.

[0161] The solution to improve antenna performance through scene recognition can accurately identify the current usage scenario based on antenna impedance detection, sensor data, APP whitelist information and other information. On the premise of meeting power compliance requirements, it can realize intelligent power allocation of the two transmission channels and improve the overall performance of the antenna.

[0175] In some embodiments, the configuration unit 1903 is used to configure the maximum transmission power of the second target antenna to a third transmission power when the current usage scenario of the terminal device is a usage scenario in which at least one antenna is blocked, and the third transmission power meets the compliance requirements of one or more indicators, and the second target antenna is a blocked antenna.

[0176] In some embodiments, the configuration unit 1903 is further configured to, when the current usage scenario of the terminal device is a usage scenario in which at least one antenna is blocked, perform impedance tuning on the blocked antenna.

[0177] In some embodiments, configuration unit 1903 is used to configure the maximum transmission power of the antenna to a fourth transmission power when the current usage scenario of the terminal device is a usage scenario in which the antenna is not blocked, and the fourth transmission power is the maximum transmission power of the antenna in a free space scenario.
