Description

Method and equipment for adjusting transmission power
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and a device for adjusting transmit power.
Background
Along with the wide popularization of mobile terminal equipment, the frequency of using the mobile terminal equipment by people is higher and higher, and meanwhile, the influence of the electromagnetic radiation of the mobile terminal equipment on a human body is more and more paid more attention by people. In the authentication process of the mobile terminal device, the SAR (Specific Absorption Rate) index test becomes more and more strict.
An antenna of a mobile terminal is used to transmit and receive electromagnetic waves. Under the condition that the distance between the mobile terminal and the human body is constant, the SAR value is larger when the transmitting power of the mobile terminal is larger. In general, the structure and material of the antenna may affect the transmission power, for example, the radiation of the internal antenna to the human body is smaller than that of the external antenna, so in order to meet the SAR value of the mobile terminal, the structure and material of the antenna generally need to be adjusted, and the difficulty coefficient is relatively large.
In addition, the mobile terminal has two main radiation representations, one is a far-field radiation index TRP (Total Radiated Power), which represents the communication capability of the mobile terminal, and the larger the index is, the better the transmission Power is, the larger the transmission Power is, the better the transmission Power is; the other is a near-field radiation index SAR which represents the size of electromagnetic waves absorbed by human tissues with unit mass, and the smaller the index is, the better the index is, namely the smaller the emission power is, the better the index is. The TRP index and the SAR index are mutually restricted, and the smaller the SAR value is, the smaller the electromagnetic wave absorbed by a human body is, and the smaller the damage to the human body is, so in order to meet the SAR index, the TRP index needs to be adjusted.
At present, in order to meet SAR indexes, the problems of adjusting the structure and materials of a hardware antenna and adjusting TRP indexes exist.
Disclosure of Invention
The invention provides a method and equipment for adjusting transmission power, which are used for solving the problems that in the prior art, in order to meet SAR indexes, the hardware antenna is difficult to adjust, and the TRP value of a mobile terminal is fixed at a lower value.
In a first aspect, a method for adjusting transmit power provided in an embodiment of the present invention includes: after the terminal determines that the terminal is in a static state from a motion state through the position sensor, the distance between the terminal and a user is determined through the distance sensor; the terminal compares the determined distance with the previously determined distance between the terminal and the user, and determines the distance change state between the terminal and the user according to the comparison result; the terminal adjusts the current transmitting power value according to the determined distance change state and the preset transmitting power value corresponding to the currently determined distance; wherein the distance change state is one of the distance from the terminal to the user from near to far, the distance from the terminal to the user from far to near and the distance from the terminal to the user from constant.
According to the method, the terminal determines the distance from the terminal to the user according to the distance sensor after determining that the terminal is in the moving state to the static state through the position sensor. The terminal compares the distance between the terminal and the user determined this time with the distance between the terminal and the user determined last time, and determines the distance change state between the terminal and the user according to the comparison result, wherein the change state is one of the case that the distance between the terminal and the user is from near to far, the distance between the terminal and the user is from far to near, and the distance between the terminal and the user is not changed. And the terminal adjusts the current transmitting power according to the changing state and the preset transmitting power corresponding to the distance between the current terminal and the user. The method adjusts the current transmitting power according to the preset transmitting power, so that the SAR value of the terminal meets the SAR index under the condition of not adjusting the structure and the material of the hardware antenna and the TRP index, and further the influence of electromagnetic waves on a human body is reduced.
In a possible implementation manner, the terminal judges whether the current SAR value exceeds the maximum SAR value; if the current SAR value exceeds the maximum SAR value, the terminal reduces the current transmitting power value according to the set compensation value and returns to the step of judging whether the current SAR value exceeds the maximum SAR value; and if the current SAR value does not exceed the maximum SAR value, the terminal stops adjusting the current transmitting power value.
Firstly, the terminal judges whether the current SAR value exceeds the maximum SAR value, if the current SAR value exceeds the maximum SAR value, the SAR value needs to be reduced according to the set compensation value; and if the SAR value does not exceed the SAR maximum value, stopping adjusting the current transmission power value. That is, the SAR value exceeds the SAR maximum value, the transmit power value is decreased until the SAR value does not exceed the SAR maximum value. When the SAR value exceeds the SAR maximum value, the influence of electromagnetic radiation on a human body is large, so that the transmission power is reduced, the SAR value does not exceed the SAR maximum value, and the influence of the electromagnetic radiation on the human body can be reduced.
In a possible implementation manner, the distance change state is that the distance between the terminal and the user is from near to far; after the terminal is in a moving state to a static state, before a preset transmitting power value corresponding to the distance between the terminal and the user is determined, the distance between the terminal and the user is determined to be smaller than a preset maximum distance.
According to the method, when the distance from the terminal to the user is from near to far, after the terminal is in a moving state to a static state, before the preset transmitting power value corresponding to the distance from the terminal to the user is determined, the distance from the terminal to the user is determined to be smaller than the preset maximum distance. Because the influence of electromagnetic radiation on a human body is large when the distance of the terminal is smaller than the preset maximum distance, after the terminal is in a moving state to a static state, if the distance from the terminal to a user is smaller than the preset maximum distance, the preset transmitting power corresponding to the distance from the terminal to the user needs to be determined.
In a possible implementation manner, the distance change state is that the distance between the terminal and the user is from far to near; after the terminal is in a moving state and a static state, before a preset transmitting power value corresponding to the distance between the terminal and the user is determined, the distance between the terminal and the user is determined to be smaller than a preset maximum distance, and an SAR value corresponding to the distance between the terminal and the user exceeds the SAR maximum value.
In the method, when the distance from the terminal to the user is from far to near, and the terminal is in a static state from a moving state, if the terminal determines that the distance from the terminal to the user is smaller than the preset maximum distance and the SAR value corresponding to the distance from the terminal to the user exceeds the SAR maximum value, the terminal determines the preset transmitting power value corresponding to the distance from the terminal to the user. That is to say, when the distance between the terminal and the user is from far to near, if the distance between the changed position of the terminal and the user is smaller than the preset maximum distance and the SAR value corresponding to the distance between the terminal and the user exceeds the maximum SAR value, the transmission power of the terminal needs to be adjusted to the preset transmission power corresponding to the distance between the terminal and the user. After the transmitting power of the terminal is adjusted to the preset power corresponding to the distance, the SAR value is relatively reduced, and therefore the influence of electromagnetic radiation on a human body is reduced.
In a possible implementation manner, the distance change state is that the distance between the terminal and the user is not changed; after the terminal is in a moving state to a static state, before the terminal determines a preset transmission power value corresponding to a distance between the terminal and a user, the method further includes: after the terminal is in a moving state to a static state, the distance between the terminal and the user is determined to be smaller than a preset maximum distance, an SAR value corresponding to the distance between the terminal and the user exceeds the SAR maximum value, and the current transmitting power value is not adjusted.
In the method, the distance between the terminal and the user is unchanged, if the terminal is in a moving state to a static state, the distance between the changed position of the terminal and the user is determined to be smaller than the preset maximum distance, the SAR value corresponding to the distance between the terminal and the user exceeds the SAR maximum value, and the terminal does not adjust the current transmission power, the terminal needs to determine the preset transmission power value corresponding to the distance between the terminal and the user. After the current transmitting power of the terminal is adjusted to the preset transmitting power value corresponding to the current distance, the SAR value is relatively reduced, and therefore the influence of electromagnetic radiation on a human body is reduced.
In a possible implementation manner, after the terminal is in a moving state to a static state, it is determined that the distance between the terminal and the user is smaller than the preset maximum distance, and the SAR value corresponding to the distance between the terminal and the user exceeds the maximum SAR value, and the current transmission power value is adjusted, and then the current transmission power value is gradually reduced according to the set compensation value until the current SAR value does not exceed the maximum SAR value.
In the method, if the terminal judges that the distance between the terminal and the user is less than the preset maximum distance after the terminal is in the moving state to the static state, the SAR value corresponding to the distance between the terminal and the user exceeds the SAR maximum value, and the current transmitting power is adjusted, in order to meet the SAR index, the current transmitting power value is required to be gradually reduced according to the set compensation value until the current SAR value does not exceed the SAR maximum value, namely the current SAR value meets the SAR index. After the current SAR value accords with the SAR index, the influence of electromagnetic radiation on a human body can be reduced.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
When a mobile terminal, such as a mobile phone, is in a call state, the mobile phone is close to a human body, and the mobile phone has electromagnetic radiation to the human body. The closer the mobile phone is to the human body, the greater the electromagnetic radiation, that is, the greater the SAR value. When the distance between the mobile phone and the human body exceeds a certain distance, the distance is called as the maximum distance in the following, and the electromagnetic radiation can be regarded as having no influence on the human body. When the distance between the mobile phone and the human body does not exceed the maximum distance, in order to meet the SAR index, the transmitting power of the mobile phone needs to be reduced.
The terminal in the embodiment of the invention can be a mobile phone, a tablet computer and other terminals with electromagnetic radiation.
The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 1, a method for adjusting a transmission power value provided in an embodiment of the present invention specifically includes the following steps:
s100, after the terminal determines that the terminal is in a static state from a motion state through a position sensor, determining the distance between the terminal and a user through a distance sensor;
s101, the terminal compares the determined distance with the distance between the terminal and the user determined at the previous time, and determines the distance change state between the terminal and the user according to the comparison result;
and S102, the terminal adjusts the current transmitting power value according to the determined distance change state and the preset transmitting power value corresponding to the currently determined distance.
The terminal firstly determines the terminal from a moving state to a static state through the position sensor, and then determines the distance between the terminal and a user according to the distance sensor. The terminal compares the distance between the terminal and the user determined this time with the distance between the terminal and the user determined last time, and determines the distance change state between the terminal and the user according to the comparison result, wherein the change state is one of the distance between the terminal and the user from near to far, the distance between the terminal and the user from far to near and the distance between the terminal and the user from constant. And the terminal adjusts the current transmitting power according to the changing state and the preset transmitting power corresponding to the distance between the current terminal and the user. The method adjusts the current transmitting power according to the preset transmitting power, so that the SAR value of the terminal meets the SAR index under the condition of not adjusting the structure and the material of the hardware antenna and the TRP index, and further the influence of electromagnetic waves on a human body is reduced.
The embodiment of the invention is based on a high-pass processor, and firstly, a scene-distance-preset transmitting power relation mapping table is established in a laboratory environment, wherein the relation mapping table is a corresponding preset transmitting power value at different distances from a human body under the condition of meeting an SAR value. Because the terminal is in different angles and different environments, and the transmission power at the same distance may be different, multiple groups of transmission power meeting the SAR index at the same distance may be counted, and then the average or mode of the multiple groups of transmission power is calculated to be used as the preset transmission power at the distance. The distance values are taken in millimeters upwards.
In implementation, the closer the terminal is to the human body, the larger the SAR value, and in order to ensure the SAR index, the transmission power of the terminal needs to be reduced, thereby reducing the SAR value. When the distance between the terminal and the human body exceeds a certain range, the electromagnetic radiation may be regarded as having no influence on the human body, and the distance is defined as a maximum distance.
As shown in fig. 2 and fig. 3, fig. 2 is a schematic diagram of a scene-distance mapping table, and fig. 3 is a schematic diagram of a scene-preset transmission power mapping table.
As shown in fig. 2, when the scene value is 0, the scene is a special scene, and at this time, the distance does not need to be recorded, when the scene value is 1, the distance is 0mm, and when the scene value is 2, the distance is 1mm, which is illustrated here and cannot be listed one by one, and when the specific implementation is implemented, the scene-distance mapping table is established as needed.
As shown in fig. 3, since the scene value 0 is a special scene, the scene 0 corresponds to the compensation power value, when the scene value is 0, the compensation power value is 0.2dB, when the scene value is 1, the preset transmission power is 18dBm, when the scene value is 2, the preset transmission power is 19dBm, which is illustrated here and cannot be listed one by one, and a scene-preset transmission power mapping table is established as required in specific implementation.
It should be noted that, when the scene value is 0, the corresponding compensation power value is, that is, in this scene, compensation is performed according to 0.2dB, where 0.2dB represents power gain and is a reduction of power, so the unit is dB, and other scenes represent preset transmission power, so the unit is dBm.
Establishing a scene-distance mapping table and a scene-preset transmitting power mapping table should be in one-to-one correspondence, taking fig. 2 and fig. 3 as an example, when the distance is 1mm, the corresponding scene value in fig. 2 is 2, and when the scene value in fig. 3 is 2, the corresponding preset transmitting power is 19dBm, that is, when the distance is 1mm, the preset transmitting power of the terminal is 19 dBm.
After the mapping table of scene-distance-preset transmission power is established, the adjustment of transmission power is further described below.
Taking a high-pass processor as an example, as shown in fig. 4, a block diagram of an adaptive SAR value adjusting apparatus is shown. The terminal is divided into an AP (Application Processor) side and a BP (Baseband Processor) side, wherein the AP side mainly includes an operating system, a user interaction interface, an Application program and the like, and the BP side mainly includes communication control software related to a Baseband Modem, such as implementation of functions of signal processing, radio frequency control and the like. More intuitively, the BP side can be labeled as the Modem side, as shown in FIG. 4.
As shown in fig. 4, the SAR sensor at the AP side of the terminal is used to acquire a SAR value of a current distance, the location sensor is used to determine a state of the terminal, the distance sensor is used to detect a distance between the terminal and a user, and the RF (Radio Frequency) module at the Modem side is used to adjust a transmission power of the terminal.
When the AP communicates with the Modem, the AP may send a Message through a QMI (Qualcomm Message Interface, high-pass Message Interface) Interface, where the QMI mechanism is a mechanism for communicating between the AP side and the Modem side based on a high-pass platform.
For example, after the terminal determines that the terminal is in a moving state to a static state through the position sensor, when the distance sensor monitors that the distance between the terminal and the user is 1mm, the scene-distance mapping table shown in fig. 2 is searched, and the obtained scene value is 2, the scene value 2 is sent to the Modem through the QMI interface, the Modem searches the scene-preset transmission power mapping table shown in fig. 3, and when the obtained scene is 2, the corresponding preset transmission power is 19dBm, and the transmission power of the RF module is adjusted to 19 dBm.
When a user uses the terminal, the motion process of the terminal is a process from a static state to a motion state and then to the static state. The terminal is from a static state to a moving state, and the distance between the terminal and the user at the static state is defined as the distance between the terminal and the user at the previous time; the terminal is in a moving state to a static state, and in the static state, the distance between the terminal and the user is defined as the distance between the current terminal and the user.
And comparing the distance between the current terminal and the user with the distance between the terminal and the user at the previous time, and determining the distance change state between the terminal and the user according to the comparison result.
The distance change state is divided into three types, the first type is that the distance between the terminal and the user is from near to far, the second type is that the distance between the terminal and the user is from far to near, and the third type is that the distance between the terminal and the user is not changed.
For example, if the distance between the current terminal and the user is 2mm, and the distance between the last terminal and the user is 1mm, it is determined that the distance change state of the terminal is from near to far; when the distance between the terminal and the user is 1mm and the distance between the terminal and the user at the last time is 2mm, determining that the distance change state of the terminal is from far to near; and when the distance between the terminal and the user is 1mm and the distance between the terminal and the user is 1mm last time, determining that the distance change state of the terminal is unchanged.
The distance between the terminal and the user can be monitored through the distance sensor in the terminal, in implementation, the distance between the terminal and the user can be monitored for a long time through the distance sensor according to needs, meanwhile, the distance between the terminal and the user, which is monitored by the distance sensor at the previous time, can be stored in the terminal, and the distance monitored at the previous time and the distance monitored at this time can be compared through the terminal, so that the change state of the distance between the terminal and the user can be judged.
For example, the distance sensor in the terminal is set to monitor the distance between the terminal and the user every 60ms, the distance between the terminal and the user monitored in the last 60ms is 1mm, and the distance between the terminal and the user monitored in the current 60ms is 2mm, so that the position change of the terminal is determined to be from near to far.
When a user uses a terminal, the distance between the terminal and the user can be changed frequently, and after the distance is changed, in order to meet the SAR index, the transmitting power of the terminal needs to be changed.
After the terminal determines that the terminal is in a moving state to a static state through the position sensor, firstly, the distance between the terminal and a user is determined through the distance sensor, and then, the preset transmitting power corresponding to the distance between the terminal and the user is determined.
After the terminal is in a moving state to a static state, determining the distance between the terminal and the user, for example, the distance between the terminal and the user is 2mm, the AP searches a distance-scene mapping table shown in fig. 2 according to the distance between the terminal and the user, determines that a corresponding scene value is 3 when the distance between the terminal and the user is 2mm, the AP sends the scene value 3 to the Model through the QMI interface, the Model queries a scene-preset transmission power mapping table shown in fig. 3 after receiving the scene value 3 sent by the AP, obtains that the preset transmission power is 20dBm when the scene value is 3, and determines that a corresponding preset transmission power value is 20dBm when the distance between the terminal and the user is 2 mm.
And after the preset transmitting power is determined, the terminal adjusts the current transmitting power according to the determined preset transmitting power.
If it is determined that the preset transmit power is 20dBm, as shown in fig. 4, the RF module adjusts the current transmit power to 20 dBm.
After the terminal adjusts the current transmission power, because the terminal is at different angles and different environments at the same distance, the transmission power may be different, and after the terminal adjusts the transmission power to the preset transmission power, the SAR value may exceed the standard, and at this time, it is necessary to check whether the SAR value exceeds the standard after the terminal adjusts the transmission power to the preset transmission power.
The method for judging whether the current SAR value exceeds the maximum SAR value by the terminal is that the terminal collects the current SAR value through the SAR sensor and then judges whether the current SAR value exceeds the maximum SAR value.
If the current SAR value exceeds the SAR maximum value, the current transmit power of the terminal needs to be reduced. When the current transmission power is reduced, the communication quality of the terminal may be affected, so that the current transmission power cannot be reduced too much at a time, and a compensation value needs to be set, and the transmission power is reduced according to the set compensation value, for example, the compensation value is 0.2 dB.
After the terminal reduces the transmitting power according to the set compensation value, the terminal also needs to return to the step of judging whether the current SAR value exceeds the SAR maximum value, detect whether the current SAR value exceeds the SAR maximum value again, and repeat the steps until the SAR value does not exceed the SAR maximum value.
And if the current SAR value does not exceed the maximum SAR value, the terminal stops adjusting the current transmission power value.
In specific implementation, when the RF module adjusts the transmission power to meet the SAR index, the terminal adjusts the current transmission power according to the determined distance change state and the preset transmission power corresponding to the currently determined distance.
The distance change state between the terminal and the user is divided into that the distance between the terminal and the user is changed from near to far, the distance between the terminal and the user is changed from far, and the distance between the terminal and the user is not changed.
Three states in which the distance between the terminal and the user is from near to far, from far to near, and constant are described below.
1. When the distance between the terminal and the user is from near to far, after the terminal is in a moving state to a static state, whether the distance between the terminal and the user is smaller than a preset maximum distance or not is determined, and if the distance is smaller than the preset maximum distance, the terminal determines the preset transmitting power of the current distance.
For example, the preset maximum distance is 8mm, when the distance between the terminal and the user is from near to far, if the distance between the terminal and the user is 2mm after the terminal is in a moving state to a static state, the terminal needs to determine the corresponding preset transmitting power when the distance between the terminal and the user is 2 mm; if the distance between the terminal and the user is 10mm after the terminal is in the moving state and the static state, namely the distance between the terminal and the user exceeds the maximum distance, adjusting the transmitting power of the terminal to the default transmitting power; if the terminal moves again, and the distance between the terminal and the user is 12mm after the terminal is stationary, the transmitting power of the terminal does not need to be adjusted.
And after the preset transmitting power of the current distance of the terminal is determined, the terminal adjusts the current transmitting power value according to the determined preset transmitting power value. Since the terminal is at different angles and different environments at the same distance and the transmission power may be different, the SAR value may exceed the standard after the terminal adjusts the transmission power to the preset transmission power, and the terminal needs to detect the SAR value again. The terminal acquires a current SAR value through the SAR sensor and then judges whether the current SAR value exceeds the maximum SAR value. If the current SAR value exceeds the maximum SAR value, the current transmitting power of the terminal needs to be reduced; and if the current SAR value does not exceed the maximum SAR value, stopping adjusting the current transmitting power value of the terminal.
And if the distance between the terminal and the user is not less than the preset maximum distance after the terminal is in the moving state to the static state, the terminal finishes adjusting the transmitting power.
2. When the distance from the terminal to the user is from far to near, after the terminal is in a moving state to a static state, whether the distance between the terminal and the user is smaller than a preset maximum distance or not is determined, whether an SAR value corresponding to the distance between the terminal and the user exceeds an SAR maximum value or not is determined, and if the distance between the terminal and the user is smaller than the preset maximum distance and the SAR value corresponding to the distance between the terminal and the user exceeds the SAR maximum value, the terminal determines preset transmitting power corresponding to the distance between the terminal and the user.
For example, the preset maximum distance is 8mm, when the distance between the terminal and the user is from far to near, the distance between the terminal and the user is 2mm after the terminal is in a moving state to a static state, and at this time, the SAR value acquired by the SAR sensor of the terminal exceeds the maximum SAR value, the terminal needs to determine the corresponding preset transmission power when the distance between the terminal and the user is 2 mm.
And after the preset transmitting power of the current distance of the terminal is determined, the terminal adjusts the transmitting power value of the current terminal according to the determined preset transmitting power value. Since the terminal is at different angles and different environments at the same distance and the transmission power may be different, the SAR value may exceed the standard after the terminal adjusts the transmission power to the preset transmission power, and the terminal needs to detect the SAR value again. The terminal acquires a current SAR value through the SAR sensor and then judges whether the current SAR value exceeds the maximum SAR value. If the current SAR value exceeds the maximum SAR value, the current transmitting power of the terminal needs to be reduced; and if the current SAR value does not exceed the maximum SAR value, stopping adjusting the current transmitting power value of the terminal.
And if the distance between the terminal and the user is not less than the preset maximum distance after the terminal is in the moving state to the static state and/or the SAR value corresponding to the distance between the terminal and the user does not exceed the SAR maximum value, the terminal finishes adjusting the transmission power of the terminal.
3. When the distance from the terminal to the user is unchanged, after the terminal is in a moving state to a static state, determining whether the distance from the terminal to the user is smaller than a preset maximum distance, determining whether an SAR value corresponding to the distance from the terminal to the user exceeds the maximum SAR value, and determining whether the terminal adjusts the current transmission power. And if the distance between the terminal and the user is smaller than the preset maximum distance, the SAR value corresponding to the distance between the terminal and the user exceeds the SAR maximum value, and the terminal does not adjust the current transmission power, the terminal determines the preset transmission power corresponding to the distance between the terminal and the user after the position is stopped.
And after the preset transmitting power of the current distance of the terminal is determined, the terminal adjusts the current transmitting power value of the terminal according to the determined preset transmitting power value. Since the terminal is at different angles and different environments at the same distance and the transmission power may be different, the SAR value may exceed the standard after the terminal adjusts the transmission power to the preset transmission power, and the terminal needs to detect the SAR value again. The terminal acquires a current SAR value through the SAR sensor and then judges whether the current SAR value exceeds the maximum SAR value. If the current SAR value exceeds the maximum SAR value, the current transmitting power of the terminal needs to be reduced; and if the current SAR value does not exceed the maximum SAR value, stopping adjusting the current transmitting power value of the terminal.
And if the terminal is in a moving state to a static state, the distance between the terminal and the user is not less than the preset maximum distance, or/and the SAR value corresponding to the distance between the terminal and the user does not exceed the SAR maximum value, and the terminal does not adjust the current transmission power, the terminal finishes adjusting the transmission power.
There is also a possible situation when the distance from the terminal to the user is constant.
When the distance from the terminal to the user is unchanged, the terminal determines whether the distance from the terminal to the user is smaller than a preset maximum distance after the terminal is in a moving state to a static state, determines whether an SAR value corresponding to the distance from the terminal to the user exceeds the SAR maximum value, determines whether the current transmitting power of the terminal is adjusted, and if the distance from the terminal to the user is smaller than the preset maximum distance after the terminal is in the moving state to the static state, the SAR value corresponding to the distance from the terminal to the user exceeds the SAR maximum value and the current transmitting power of the terminal is adjusted, the terminal reduces the current transmitting power according to a set compensation value until the current SAR value does not exceed the SAR maximum value.
If the distance between the terminal and the user is not less than the preset maximum distance after the terminal is in the moving state to the static state, or/and the SAR value corresponding to the distance between the terminal and the user does not exceed the SAR maximum value, and the current transmission power of the terminal is adjusted, the terminal finishes adjusting the transmission power of the terminal.
The above is an explanation of the case that the distance from the terminal to the user is not changed, and the case that the distance from the terminal to the user is not changed is divided into two cases, where both of the two cases are under the premise that the distance from the terminal to the user is smaller than the preset maximum distance and the SAR value corresponding to the distance from the terminal to the user exceeds the maximum SAR value, one of the two cases is that the current transmission power is not adjusted, and the other case is that the current transmission power is adjusted.
If the current transmission power is not adjusted, the terminal needs to determine the preset transmission power according to the distance between the terminal and the user, and if the current transmission power is adjusted before, the terminal reduces the transmission power according to the set compensation value until the SAR value does not exceed the SAR maximum value.
As can be seen from the above description, when the distance between the terminal and the user changes, the steps of adjusting the transmission power are very similar in the two cases, that is, the distance between the terminal and the user changes from far to near and the distance between the terminal and the user does not change, so that the two cases can be combined into one case, and therefore, the following drawings are respectively described for the two cases when the distance between the terminal and the user changes.
