It decreases.
Specifically, terminal device reduces the transmission power of transmitting radiofrequency signal in the embodiment of the present invention, need to set in terminal
Standby TRP value instruction terminal equipment can be by scene that antenna carries out wireless communication.Tune i.e. provided in an embodiment of the present invention
In the method for saving antenna transmission power, need to combine the SAR value and TRP value of terminal device.
It should be noted that the method provided in an embodiment of the present invention for adjusting antenna transmission power, is applied to terminal device,
It include antenna in the terminal device.Wherein, in the case where terminal device emits radiofrequency signal by antenna, which can
To obtain the first image to obtain the biological characteristic of user.In the biological characteristic of acquisition and the feelings of default head biometric matches
Under condition, the transmission power of the adjustable transmitting radiofrequency signal of terminal device is target power, which is and default head
The corresponding transmission power of biological characteristic.Wherein, since terminal device is available to including user's head feature, (such as ear is special
Sign) the first image, therefore terminal device can relatively accurately determine the head of user close to equipment, rather than other objects
Other of body or user position (such as hand) are close to terminal device.To which terminal device can will emit the transmitting of radiofrequency signal
Power regulation be transmission power corresponding with default head biological characteristic, it can by transmission power adjustment be lower transmitting function
Rate is to reduce the SAR value of terminal device.In this way, when can accidentally reduce it to avoid terminal device by antenna transmitting radiofrequency signal
Transmission power, that is, improving terminal device reduces the accuracy of transmission power.
In one possible implementation, in the method provided in an embodiment of the present invention for adjusting antenna transmission power, in advance
If biological characteristic is default eyebrow feature, presets eye feature, presets at least one in nose feature and default mouth feature,
I.e. for terminal device close to the face of user, target power is the first power, is passing through antenna with the first power emission radiofrequency signal
When terminal device specific absorption rate SAR value be less than or equal to maximum permissible value；Default biological characteristic is default ear feature, i.e., eventually
For end equipment close to the ear of user, target power is the second power, whole when by antenna with the second power emission radiofrequency signal
The SAR value of end equipment is less than or equal to maximum permissible value；Wherein, the second power is less than or equal to the first power.
It is understood that usual user sets terminal in the scene that terminal device emits radiofrequency signal by antenna
It is standby close to user's head to realize voice communication, specially user by terminal device close to ear, and the face of user, such as eye
Eyeball, eyebrow, nose and mouth etc. are usually compared for ear apart from terminal device farther out.
It is understood that terminal device is closer apart from user's head, the SAR value of the terminal device is bigger；Conversely, terminal
Equipment is remoter apart from user's head, and the SAR value of the terminal device is smaller.
It is understood that scene of the terminal device close to the scene of user's ear compared to close user's face, terminal
The degree that equipment reduces transmission power is bigger, i.e., the second power is less than the first power.Wherein, terminal device adjusts transmission power
In the process, it can be and transmission power be reduced to target power by default transmission power.
It should be noted that in terminal device far from user's head, and the SAR value of the terminal device meet the requirements it is (i.e. small
In or equal to maximum permissible value) when, which emits transmission power when radiofrequency signal by antenna, such as maximum allowable
Transmission power can be above-mentioned default transmission power.
Optionally, the first power is less than or equal to default transmission power, and the second power is less than default transmission power.
Specifically, being default eyebrow in biological characteristic of the terminal device in the first image of acquisition and default biological characteristic
Feature presets eye feature, presets at least one (i.e. facial biological characteristic) in nose feature and default mouth feature
Match, and the first power be less than default transmission power in the case where, the transmission power adjustment for emitting radiofrequency signal is by terminal device
When target power (i.e. the first power), it is reduction of transmission power；In the case where the first power is equal to default transmission power,
Terminal device can keep the transmission power of transmitting radiofrequency signal constant.In addition, in terminal device in the first image of acquisition
Biological characteristic and default ear characteristic matching, and the second power be less than default transmission power in the case where, terminal device will send out
When the transmission power adjustment for penetrating radiofrequency signal is target power (i.e. the second power), it is reduction of transmission power.
In addition, on the one hand requiring the SAR value of terminal device to be less than or equal to maximum allowable during terminal equipment in communication
Value；On the other hand, the performance of the antenna in terminal device is also required to meet the requirements, to realize that terminal device is preferably wirelessly connected
Function, that is, transmission power when terminal device being required to emit radiofrequency signal by antenna are higher.In this way, terminal device adjusts transmitting
During power, it can be and transmission power is increased to default transmission power by lower target power.That is, terminal
The SAR value and TRP value of equipment should be required completely, that is, need to take into account terminal device while reducing the SAR value of terminal device
TRP value.
It should be noted that terminal device can be in the method provided in an embodiment of the present invention for adjusting antenna transmission power
Biological characteristic in first image of terminal device acquisition is compared with multiple default head biological characteristics, the biological characteristic
And have default head biometric matches (such as default ear feature) when, terminal device can largely lower transmitting function
Rate；And the biological characteristic is with the default head biological characteristic (such as default eye feature) having when matching, terminal device can be smaller
Reduce transmission power to degree, in this embodiment it is not even necessary to reduce transmission power.In this way, can be further improved terminal device reduces transmitting
The accuracy of power, and then the better performances for penetrating antenna when power does not need to reduce can be made.
In one possible implementation, in the method provided in an embodiment of the present invention for adjusting antenna transmission power, in advance
If ear feature includes presetting left characteristic of ear and default auris dextra feature；Default ear feature is to preset left characteristic of ear, the second power
For the first sub- power；Default ear feature is default auris dextra feature, and the second power is the second sub- power, the first sub- power and second
Sub- power is different.
It is understood that carrying out voice since user usually uses some ear (such as auris dextra) using terminal equipment
Call, therefore terminal device only one general ear when emitting radiofrequency signal is closer apart from terminal device.Alternatively, due to
The use habit of user, user may when listening to the voice in voice call process using an ear so that the ear away from
It is closer from terminal device；And when listening to the voice in voice call process using another ear, so that ear distance is eventually
End equipment is farther out.In this way, related technical personnel etc. can be tested by SAR, obtain terminal device apart from the left ear of user it is relatively close or
When terminal device is closer apart from user's auris dextra, corresponding second power is to get sub to the first different sub- power and second
Power.
It should be noted that in the method provided in an embodiment of the present invention for adjusting antenna transmission power, due in default ear
Piece feature is the first sub- power in the case where presetting left characteristic of ear, and is default auris dextra feature in default head biological characteristic
In the case of the second sub- power it is different whether need to adjust transmitting function so that terminal device can further refine to distinguish
Rate, such as whether reducing transmission power.In this way, can be further improved terminal device reduces the accuracy of transmission power.
It in one possible implementation, illustratively, as indicated at 4, is adjusting antenna provided in an embodiment of the present invention
Another flow diagram of the method for transmission power.In method shown in Fig. 4, the S301 in above-described embodiment can pass through
S301a is realized:
S301a, in the case where emitting radiofrequency signal by antenna, terminal device obtains the first image and first distance number
Value, first distance numerical value are the distance between terminal device and user's head numerical value.
It is understood that in order to avoid terminal device according in the first image of acquisition biological characteristic and default head
The case where user's head is at a distance from terminal device cannot be accurately determined when biometric matches, terminal device can be further
