[0024] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It should be understood that many specific details are set forth in the following description to facilitate a full understanding of the present application, but the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0027] SAR (Specific Absorption Rate) value represents the amount of radiation that a living organism (including the human body) is allowed to absorb per unit kilogram. It is defined as the electromagnetic power absorbed or consumed by a unit mass of biological tissue, and the unit is W / kg. The SAR value represents the impact of radiation on the human body and is the most direct test value. The SAR value has data for the whole body, local area or limbs. Among them, the lower the SAR value, the less radiation is absorbed by the organism. The two current international SAR value standards are 1.6W / Kg of the FCC (Federal Communications Commission) and 2.0W / Kg of the European Union. The SAR value test is to test the radio electromagnetic wave energy generated by the antenna of the terminal through the test equipment to measure how much electromagnetic wave radiation the organism absorbs. In order to avoid the terminal SAR value exceeding the standard, the terminal often needs to be processed to reduce the SAR value.
[0028] The main SAR reduction solutions in related technologies include: a terminal has a built-in SAR sensor chip, which detects whether the terminal is close to human tissue through the sensor chip, thereby helping the terminal to reduce SAR. However, in the current SAR reduction solution, since a special sensor chip is required, the terminal cost and PCB design area will be increased.
[0029] In view of this, an embodiment of the present application provides an optimization method, by which the terminal can achieve optimization of reducing the SAR value of the terminal without increasing the hardware cost.
[0030] It should be noted that the optimization method provided in the embodiment of the present application can be executed by a terminal or a central processor in the terminal, wherein the terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices and portable wearable devices, and the IoT devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The following is an example of the application of this method to a terminal.
[0031] In one embodiment, Figure 1 As shown, an optimization method is provided, comprising the following steps:
[0032] Step 101: Determine a first antenna from antennas of the terminal according to the use state of the terminal. The first antenna is an antenna whose distance to the human body is less than a target distance threshold.
[0033] In the process of using the terminal by the user, the terminal may have different usage states in different scenarios, such as the usage state of the target application in the terminal and the state of the user using the terminal. In addition, the terminal may generally include multiple antennas, each of which may be located at a different position of the terminal.
[0034] In different usage states, different body parts of the user are closer to different antennas in the terminal, that is, in a certain usage state, the distance between a certain body part of the user and the first antenna in the terminal is less than the target distance threshold.
[0035] The antenna in the terminal can be used to transmit the signal generated in the terminal. The SAR value is strongly related to parameters such as the transmit power of the antenna in the terminal and is proportional to the transmit power. The higher the transmit power, the higher the SAR value. In addition, the closer the user's body is to the antenna in the terminal, the greater the electromagnetic wave radiation absorbed by the human body.
[0036] Based on this, it is necessary to determine the first antenna whose distance from the human body is less than the target distance threshold when the terminal is currently in use, and adjust the transmission power of the first antenna to ensure that the SAR value complies with regulations and avoids affecting the human body.
[0037] Optionally, the number of the first antennas may be single or multiple, which is not specifically limited here.
[0038] Optionally, the terminal includes multiple sides. If there are multiple first antennas, each first antenna may be located at a different side of the terminal.
[0039] Step 102: determine an antenna transmission power optimization strategy according to the first antenna, and optimize the transmission power of the terminal's antenna according to the antenna transmission power optimization strategy, so that the current target SAR value of the terminal meets the SAR value limitation condition.
[0040] The target SAR value may refer to the current SAR value of the terminal. The target SAR value may be determined jointly according to the transmit power of all antennas in the terminal.
[0041] In order to make the SAR value of the terminal comply with the regulations, the terminal can determine the SAR value limit condition in real time, that is, determine the upper limit SAR value of the terminal under the premise of currently meeting the regulations in real time. By adjusting the transmit power of the antenna in the terminal so that the target SAR value of the terminal is not greater than the upper limit SAR value, the SAR value limit condition can be met.
[0042] Optionally, a plurality of optimization strategies may be pre-deployed in the terminal. According to the first antenna determined by the current usage state, the antenna transmit power optimization strategy is determined from the plurality of optimization strategies to optimize the transmit power of the antenna in the terminal.
[0043] It is understandable that the first antennas corresponding to different usage states may be different antennas, and accordingly, the antenna transmission power optimization strategies determined are also different. For example, when the antenna on the first side is determined to be the first antenna, the first optimization strategy among the multiple optimization strategies is determined to be the antenna transmission power optimization strategy; when the antenna on the second side is determined to be the first antenna, the second optimization strategy among the multiple optimization strategies is determined to be the antenna transmission power optimization strategy.
[0044] The transmit power optimization process is, for example, to reduce the transmit power of the antenna. In this way, when the transmit power is reduced, the current SAR value of the terminal is also reduced, so that the SAR value limit condition can be met.
[0045] In the above optimization method, the terminal determines the first antenna whose distance to the human body is less than the target distance threshold from the antennas of the terminal according to the usage status of the terminal; determines the antenna transmission power optimization strategy according to the first antenna, and optimizes the transmission power of the antenna of the terminal according to the antenna transmission power optimization strategy, so that the current target SAR value of the terminal meets the SAR value limitation condition. In this way, the terminal optimizes the transmission power of the first antenna that is closer to the human body based on the antenna transmission power optimization strategy, thereby optimizing the SAR value and making the current target SAR value of the terminal meet the SAR value limitation condition. That is, there is no need to add hardware, and the optimization of the terminal SAR value can be achieved by using a software algorithm. The SAR value of the terminal can be adjusted without increasing the cost of the terminal and saving its PCB area, so as to achieve the purpose of reducing SAR.
[0046] In the embodiment of the present application, in addition to optimizing the transmission power of the first antenna whose distance to the human body is less than the target distance threshold, the transmission power of the second antenna in the terminal can also be optimized, where the second antenna can refer to other antennas in the terminal except the first antenna. In this way, through comprehensive optimization processing, it is further ensured that the current target SAR value of the terminal meets the SAR value limitation condition.
[0047] In one embodiment, Figure 2 As shown, a schematic diagram of a first antenna optimization process provided by an embodiment of the present application is shown. Determine an antenna transmit power optimization strategy according to the first antenna, and optimize the transmit power of the antenna of the terminal according to the antenna transmit power optimization strategy, including:
[0048] Step 201: Acquire a first transmit power optimization strategy corresponding to a first antenna.
[0049] Step 202: Optimize the transmit power of the first antenna according to a first transmit power optimization strategy.
[0050] As mentioned above, multiple optimization strategies may be pre-deployed in the terminal. Among them, the multiple optimization strategies include an optimization strategy for the first antenna and an optimization strategy for the second antenna. Correspondingly, the antenna transmit power optimization strategy determined according to the first antenna may include at least one of a first transmit power optimization strategy for the first antenna and a second transmit power optimization strategy for the second antenna.
[0051] After the first antenna is determined, a first transmit power optimization strategy is correspondingly determined. The first transmit power optimization strategy is used to indicate how to adjust the transmit power of the first antenna.
[0052] In one embodiment, Figure 3 As shown, a schematic diagram of a second antenna optimization process provided by an embodiment of the present application is shown. The adjustment method further includes:
[0053] Step 301: Use the other antennas in the terminal except the first antenna as the second antenna.
[0054] In a possible implementation, in a use state, each antenna in the terminal is used as the first antenna, and there is no second antenna. The terminal optimizes the transmit power of each first antenna according to the first transmit power optimization strategy.
[0055] In another possible implementation, in another use state, some antennas in the terminal serve as the first antenna, and in this case, the other antennas except the first antenna may serve as the second antenna. The terminal optimizes the transmit power of each first antenna according to the first transmit power optimization strategy, and optimizes the transmit power of the second antenna according to the second antenna transmit power optimization strategy.
[0056] Step 302: Obtain a second transmit power optimization strategy corresponding to the second antenna. The first transmit power optimization strategy is different from the second transmit power optimization strategy.
[0057] Step 303: Optimize the transmit power of the second antenna according to the second transmit power optimization strategy.
[0058] The first transmit power optimization strategy is different from the second transmit power optimization strategy. For example, the degree of reduction of the transmit power of the first antenna according to the first transmit power optimization strategy is different from the degree of reduction of the transmit power of the second antenna according to the second transmit power optimization strategy.
[0059] Optionally, the distance between the second antenna and the human body is less than a candidate distance threshold, wherein the candidate distance threshold is greater than the target distance threshold. In other words, the first antenna is closer to the human body than the second antenna. Correspondingly, the degree of reduction in the transmit power of the first antenna according to the first transmit power optimization strategy may be greater than the degree of reduction in the transmit power of the second antenna according to the second transmit power optimization strategy. In this way, it is possible to ensure that the current target SAR value of the terminal meets the SAR value limitation condition, and it is also possible to avoid over-optimization of the transmit power of all antennas, thereby ensuring the communication quality of the terminal.
[0060] In an embodiment of the present application, by determining the first antenna and the second antenna, the transmit power is optimized based on their corresponding first transmit power optimization strategy and second transmit power optimization strategy, respectively, to achieve a more detailed SAR value reduction mechanism, while ensuring that the terminal meets the SAR value limitation conditions and higher communication quality.
[0061] In one embodiment, Figure 4 FIG. 1 is a flow chart of determining a first antenna according to an embodiment of the present application. Determining the first antenna from the antennas of the terminal according to the usage status of the terminal includes:
[0062] Step 401: Determine the receiver status of the terminal and the posture in which the terminal is held.
[0063] As mentioned above, the use status of the terminal includes, for example, the use status of the target application in the terminal and the state of the user using the terminal.
[0064] In one implementation, the receiver state is determined according to the usage state of the target application. The target application may be a call application that implements a call function. Exemplarily, when the usage state of the call application is in a used state, it means that the user is using the terminal to make a call, and correspondingly, the receiver state of the terminal is a receiver occupied state. When the usage state of the call application is in an unused state, it means that the user is not using the terminal to make a call, and correspondingly, the receiver state of the terminal is a receiver unoccupied state.
[0065] In another implementation, the terminal may directly detect the working status of the earpiece component in the terminal. If the earpiece component is working, the earpiece status is the earpiece occupied state; if the earpiece component is not working, the earpiece status is the earpiece unoccupied state.
[0066] In addition, the state of the user using the terminal is the posture of the terminal being held. For example, the user can use the terminal in portrait mode, and the posture of the terminal being held is the portrait posture; and when the user uses the terminal in landscape mode, the posture of the terminal being held is the landscape posture.
[0067] Optionally, the terminal includes a gyroscope, which can generate the terminal's use direction data, which is used to indicate whether the terminal is currently in landscape or portrait orientation. In this way, the terminal obtains the use direction data from the gyroscope, and determines the terminal's holding posture based on the use direction data.
[0068] Step 402: Determine a first antenna from antennas of the terminal according to the state and posture of the receiver.
[0069] Under different earpiece states and postures, the corresponding antenna is determined as the first antenna.
[0070] In the embodiment of the present application, a software algorithm is used to detect whether the terminal is in landscape or portrait mode and whether a call is in progress, so as to determine the first antenna based on this. The transmit power of the first antenna is optimized to optimize the SAR value of the antenna under different earpiece states and postures, thereby achieving the purpose of optimizing and reducing the SAR value under different usage scenarios, and improving the flexibility of optimizing the SAR value of the terminal.
[0071] The following describes a process of optimizing the transmission power of the first antenna and the second antenna under different receiver states and postures.
[0072] In one embodiment, the first antenna is determined from the antennas of the terminal according to the earpiece state and posture, including: if the earpiece state is an unoccupied state and the posture is a vertical screen posture, the antennas located on the first side, the second side and the lower side of the terminal are used as the first antenna.
[0073] The first side and the second side are opposite to each other, the lower side and the upper side are opposite to each other, and the upper side is the side closest to the receiver of the terminal. Figure 5 A schematic diagram of the position of antennas in a terminal is shown. When facing the terminal screen, antenna 3 is located at the first side of the terminal, antenna 2 is located at the second side of the terminal, antenna 2 is located at the upper side of the terminal, and antenna 4 is located at the lower side of the terminal. It can be seen that antenna 2 is close to the receiver of the terminal, and antenna 4 is close to the USB (Universal Serial Bus) port of the terminal. It should be noted that Figure 5 In the example, only one side includes one antenna. In fact, one side may include multiple antennas, which are not fully illustrated here. Figure 5 The antenna position diagram is used for illustration only, but is not intended to limit the present application.
[0074] When the handset state is that the handset is occupied and the posture is the vertical screen posture, that is, the user uses the terminal in vertical screen and does not use the terminal to make calls. At this time, the antennas on the first side, the second side, and the lower side are likely to be held by the user, that is, the distance between the antennas on the first side, the second side, and the lower side and the user's body is less than the target distance threshold, therefore, the antennas located on the first side, the second side, and the lower side in the terminal are used as the first antenna. Correspondingly, the antennas other than the first antenna are the antennas included in the upper side, therefore, the antenna on the upper side is used as the second antenna. It can be understood that at this time, the user is not holding the second antenna, and the second antenna is farther from the human body than the first antenna.
[0075] by Figure 5 For example, antenna 1, antenna 3 and antenna 4 are first antennas, and antenna 2 is the second antenna.
[0076] In one embodiment, the transmit power of the first antenna is optimized according to the first transmit power optimization strategy, including: adjusting the transmit power of the first antenna to a preset first power value. The transmit power of the second antenna is optimized according to the second transmit power optimization strategy, including: determining a second power value according to a maximum power value and an upper limit SAR value corresponding to the second antenna, and adjusting the transmit power of the second antenna to the second power value; wherein the first power value is less than the second power value.
[0077] A first power value may be pre-deployed in the terminal. When the antennas on the first side, the second side, and the lower side are the first antennas, the terminal calls the first power value and adjusts the transmit power of each first antenna to the first power value. When the transmit power of each first antenna is the first power value, the current target SAR value of the terminal satisfies the SAR value limitation condition.
[0078] Optionally, the first power value can be determined in advance through multiple experiments. The difference between the current transmit power of each first antenna and the first power value is large, so the transmit power of each first antenna is returned to the first power value, and the target SAR of the terminal is reduced accordingly to comply with regulations.
[0079] For the second antenna, the terminal can obtain the upper limit SAR value of the terminal and the maximum power value corresponding to the second antenna under the premise of currently meeting the regulations. Under the condition that the transmit power of the second antenna does not exceed the maximum power value and the SAR value of the terminal does not exceed the upper limit SAR value when the second antenna is working, the maximum transmit power that can be achieved by the second antenna is determined, and the determined maximum transmit power is used as the second power value.
[0080] Since the second antenna is farther from the human body and the first antenna is closer, the determined first power value is smaller than the second power value.
[0081] In one embodiment, the first antenna is determined from the antennas of the terminal according to the earpiece state and posture, including: if the earpiece state is that the earpiece is occupied and the posture is a vertical screen posture, the antennas located on the first side, the second side, the lower side and the upper side of the terminal are used as the first antenna.
[0082] When the receiver is in the occupied state and the posture is in the vertical posture, that is, the user uses the terminal in the vertical position to make a call. At this time, the antennas on the first side, the second side, and the lower side may be held by the user, and the antenna on the upper side is close to the receiver, and the user's head needs to be close to the receiver to make a call. Therefore, in this scenario, the antennas on the first side, the second side, the lower side, and the upper side are all used as the first antenna. Figure 5 For example, antenna 1, antenna 2, antenna 3 and antenna 4 are all first antennas. In this case, there is no second antenna.
[0083] In one embodiment, if the earpiece state is that the earpiece is occupied and the posture is a vertical screen posture, the transmission power of the first antenna is optimized according to the first transmission power optimization strategy, including: adjusting the transmission power of the antenna on the upper side to a preset third power value, and adjusting the transmission power of the antennas on the first side, the second side and the lower side to a preset fourth power value; wherein the third power value is less than or equal to the fourth power value.
[0084] The third power value and the fourth power value are pre-deployed in the terminal.
[0085] In one implementation, since the distance between the antennas on the first side, the second side, the lower side and the upper side and the human body is less than the target distance threshold, each first antenna can be adjusted to the same transmission power value, that is, the third power value is equal to the fourth power value.
[0086] In another implementation, since the first antenna on the upper side is close to the user's head and the head area is larger, the transmission power of the first antenna on the upper side can be reduced more, that is, the third power value is less than the fourth power value.
[0087] In one embodiment, the first antenna is determined from the antennas of the terminal according to the receiver state and posture, including: if the receiver state is unoccupied and the posture is a horizontal screen posture, the antennas located on the upper side and the lower side of the terminal are used as the first antenna.
[0088] When the handset state is the handset unoccupied state and the posture is the horizontal screen posture, that is, the user uses the terminal in horizontal screen and does not use the terminal to make a call. At this time, due to the horizontal screen holding, the antennas on the upper side and the lower side are likely to be held by the user. That is, the distance between the antennas on the upper side and the lower side and the user's body is less than the target distance threshold. Correspondingly, the other antennas except the first antenna are the antennas on the first side and the second side, so the antennas on the first side and the second side are used as the second antenna.
[0089] by Figure 5 For example, antenna 2 and antenna 4 are the first antenna, and antenna 3 and antenna 1 are the second antenna.
[0090] In one embodiment, if the handset state is a handset unoccupied state, and the posture is a horizontal screen posture, the transmit power of the first antenna is optimized according to the first transmit power optimization strategy, including: adjusting the transmit power of the first antenna to a preset fifth power value. The transmit power of the second antenna is optimized according to the second transmit power optimization strategy, including: determining a sixth power value according to the maximum power value and the upper limit SAR value corresponding to the second antenna, and adjusting the transmit power of the second antenna to the sixth power value; wherein the fifth power value is less than the sixth power value.
[0091] A fifth power value is deployed in the terminal. When the antennas on the upper side and the lower side are the first antennas, the terminal calls the fifth power value and adjusts the transmit power of each first antenna to the fifth power value. When the transmit power of each first antenna is the fifth power value, the current target SAR value of the terminal meets the SAR value limitation condition.
[0092] Optionally, the difference between the current transmit power of each first antenna and the first power value is relatively large, so when the transmit power of each first antenna falls back to the first power value, the target SAR of the terminal is correspondingly reduced to comply with regulations.
[0093] For the second antenna, the terminal may obtain the upper limit SAR value of the terminal and the maximum power value corresponding to the second antenna under the premise that the regulations are currently met. Under the condition that the transmit power of the second antenna does not exceed the maximum power value and the SAR value of the terminal does not exceed the upper limit SAR value when the second antenna is working, the maximum transmit power that can be achieved by the second antenna is determined, and the determined maximum transmit power is used as the sixth power value.
[0094] In the embodiment of the present application, a method for determining the first antenna and the second antenna corresponding to different combinations of earpiece states and postures and optimizing the transmission power of the first antenna and the second antenna is provided. In this way, without the need for hardware such as a SAR sensor chip, and without additional hardware costs, the SAR value optimization processing for horizontal and vertical screens and call and non-call scenarios can be more meticulously implemented, thereby improving the flexibility of SAR value optimization and maximizing the optimization of the terminal's communication experience.
[0095] For easier understanding, refer to Figure 5 , the optimization method provided in the embodiment of the present application is described below with a complete embodiment.
[0096] When a user uses a terminal, the receiver status of the terminal and the posture in which the terminal is held are detected.
[0097] If the handset state is that the handset is not occupied and the posture is the vertical screen posture, antenna 1, antenna 3 and antenna 4 may be held by the hand. At this time, the SAR values of antenna 1, antenna 3 and antenna 4 are mainly reduced, and the SAR value of antenna 2 is slightly optimized according to the actual situation to meet the SAR regulatory requirements. Exemplarily, the transmit power of the first antenna is adjusted to a preset first power value, and the second power value is determined according to the maximum power value and the upper limit SAR value corresponding to the second antenna, and the transmit power of the second antenna is adjusted to the second power value.
[0098] If the handset state is the handset occupied state and the posture is the vertical screen posture, antenna 2 is close to the head, antenna 1, antenna 3 and antenna 4 are held by the hand, then antenna 2 is lowered, and the SAR values of antenna 1, antenna 3 and antenna 4 are reduced. Exemplarily, the transmit power of the antenna on the upper side is adjusted to a preset third power value, and the transmit power of the antenna on the first side, the second side and the lower side is adjusted to a preset fourth power value; wherein the third power value is less than or equal to the fourth power value.
[0099] If the handset state is that the handset is not occupied and the posture is the horizontal screen posture, then antenna 2 and antenna 4 are held by the hand, so the SAR values of antenna 2 and antenna 4 are mainly reduced, and antenna 1 and antenna 3 slightly optimize the SAR values according to the actual situation, so as to meet the SAR regulatory requirements. Exemplarily, the transmit power of the first antenna is adjusted to a preset fifth power value, and the sixth power value is determined according to the maximum power value and the upper limit SAR value corresponding to the second antenna, and the transmit power of the second antenna is adjusted to the sixth power value; wherein the fifth power value is less than the sixth power value.
