Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application are capable of operation in sequences other than those illustrated or described herein, and that the terms "first," "second," etc. are generally used in a generic sense and do not limit the number of terms, e.g., a first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The antenna power adjustment method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1, the present application provides an antenna power adjustment method applied to an electronic device, which specifically includes the following steps:

step 101, under the condition that service data is determined to be required to be sent, sending a wireless detection signal;

wherein the wireless probe signal includes: wi-Fi signals or Bluetooth signals.

In a specific implementation manner, the wireless detection signal is a Wi-Fi signal when the electronic device transmits the service data through a data network;

in the method, when the electronic equipment is not connected with the router, the service data is transmitted through a data network, and meanwhile, wi-Fi data packets are periodically sent for radar detection of the distance between the electronic equipment and a human body; when the electronic equipment is connected with the router, the electronic equipment sends service data through a Wi-Fi signal or a data network, and if the electronic equipment sends the service data through the data network, the electronic equipment needs to send a Wi-Fi data packet at the same time for radar detection of the distance between the electronic equipment and a human body.

In another specific implementation manner, in the case that the electronic device is connected to a router and the service data is transmitted through a Wi-Fi signal, the wireless probe signal is a Wi-Fi signal used for transmitting the service data.

In this manner, when the electronic device is connected to the router, if the electronic device transmits service data through a Wi-Fi signal, it is not necessary to transmit an additional Wi-Fi signal for radar detection, and it is sufficient to detect a distance between the electronic device and a human body using the Wi-Fi signal for transmitting the service data.

It should be noted that, when there is no service data to be sent by the electronic device, the electronic device does not need to transmit a signal through the antenna, and at this time, the influence of the antenna on the human body is small, so that the SAR reduction process does not need to be started. Therefore, in the case that the electronic device has the service information transmission, the electronic device transmits a wireless probe signal to detect the distance between the electronic device and the human body according to the reflected signal of the probe signal; if no service data is sent, the SAR reduction process is not started, namely, a detection signal does not need to be generated.

Step 102, receiving a reflected signal of the wireless detection signal;

it should be noted that, if a detection signal sent by the electronic device encounters a human body or other obstacles, the detection signal is reflected back to the electronic device; if the intensity of the reflected signal received by the electronic equipment is lower than the receiving sensitivity, the electronic equipment cannot successfully receive the detection signal sent by the electronic equipment; if the received reflected signal strength is greater than or equal to the receiving sensitivity, the detection signal transmitted by the receiver can be successfully received.

For example, when the electronic device transmits service data through a Wi-Fi signal, the electronic device may periodically (may be flexibly set, for example, T =1min or the like) receive a Wi-Fi data packet sent by itself and reflected back, where the Wi-Fi data packet sent by itself and reflected back is received for detecting a distance between the electronic device and a human body.

103, adjusting the maximum transmitting power of the antenna according to the reflected signal; the antenna is used for transmitting the service data.

For example, the corresponding relationship between different reflected signal strengths and distances may be obtained in advance through experiments, and based on the corresponding relationship, the distance corresponding to the received reflected signal strength is determined, so as to obtain the distance between the electronic device and the human body, and based on the distance, the maximum transmitting power of the antenna is adjusted.

Illustratively, a distance between the electronic device and the human body may be determined based on Channel State Information (CSI) of the reflected signal, and the maximum transmission power of the antenna may be adjusted based on the distance.

For example, the distance between the electronic device and the human body may be determined based on the round trip time of the probe signal and the reflected signal and the propagation speed of the signal, and the maximum transmission power of the antenna may be adjusted based on the distance.

In the above embodiment, the electronic device sends the wireless probe signal when determining that the service data needs to be sent; and the distance between the electronic device and the human body can be detected according to the received reflected signal of the detection signal, so that the maximum transmitting power of the antenna is adjusted based on the detected distance. Compared with the prior art, the SAR sensor can be prevented from occupying the space of the electronic equipment, and the cost for deploying the SAR sensor can be reduced.

In a specific embodiment of the present application, the adjusting the maximum transmission power of the antenna according to the reflected signal includes:

determining whether the distance between the electronic equipment and the human body is smaller than or equal to a preset distance threshold value or not according to the signal energy and the spectrum characteristic of the Channel State Information (CSI) corresponding to the reflection signal;

and reducing the maximum transmitting power of the antenna under the condition that the distance between the electronic equipment and the human body is less than or equal to a preset distance threshold.

In a specific embodiment of the present application, the determining, according to the signal energy and the spectral feature of the channel state information CSI corresponding to the reflection signal, whether the distance between the electronic device and the human body is smaller than a preset distance threshold includes:

determining whether the reflection signal is a human body reflection signal according to the signal energy and the spectrum characteristics of the CSI;

and under the condition that the reflection signal is a human body reflection signal, if the signal energy is greater than an energy threshold, determining that the distance between the electronic equipment and the human body is less than the preset distance threshold.

In specific implementation, the difference between the spectral characteristics and the signal energy of the CSI information corresponding to the detection signal reflected by the human body and the object is large. Therefore, the spectrum characteristics and the signal energy of the CSI can be obtained by carrying out signal processing on the CSI information of the reflected signal; further, the spectral characteristics and the signal energy corresponding to the reflection signals reflected by the human body and the object are distinguished through a machine learning model. In this way, whether the reflected signal is a human body reflected signal can be determined according to the signal energy and the spectral characteristics of the CSI.

Further, the larger the energy of the CSI is, the farther the electronic device is from the human body, the smaller the energy of the CSI of the received reflected signal is; if the energy of the CSI of the reflected signal is larger than a threshold value W (energy threshold value), determining that the distance between the electronic equipment and the human body is smaller than a threshold value D (preset distance threshold value); if the energy of the CSI of the reflected signal is equal to the threshold W (energy threshold), it is determined that the distance between the electronic device and the human body is equal to the threshold D (preset distance threshold).

In a specific embodiment of the present application, the reducing the maximum transmission power of the antenna when the distance between the electronic device and the human body is less than or equal to a preset distance threshold includes:

under the condition that the distance between the electronic equipment and the human body is smaller than or equal to the preset distance threshold, determining a target distance range corresponding to the distance;

determining the target maximum transmitting power corresponding to the target distance range according to the corresponding relation between the preset distance range and the maximum transmitting power;

reducing the maximum transmit power of the antenna to the target maximum transmit power.

Wherein, the maximum transmitting power corresponding to different distance ranges is different.

It is understood that the smaller the distance, the smaller the maximum transmit power, in order to avoid impact on human health.

In this embodiment, each distance interval (distance range) is associated with a specific reduced maximum transmission power. For example, the distance range of 0 to 1 meter is divided into a distance interval a (e.g. 0 to 0.3 meter), a distance interval b (e.g. 0.3 to 0.6 meter) and a distance interval c (0.6 to 1 meter), such that distance interval a corresponds to a first maximum power value, distance interval b corresponds to a second maximum power value, distance interval c corresponds to a third maximum power value, and the first maximum power value < the second maximum power value < the third maximum power value. Therefore, the maximum transmitting power of the antenna can be reduced in a gradient manner, and the radiation performance of the antenna can be guaranteed to the maximum extent while the influence on human health is avoided.

The antenna power adjustment method of the present application will be described below by taking a Wi-Fi signal as a probe signal as an example.

Example 1

In this example one, the electronic device is connected to a router.

Referring to fig. 2, the method for adjusting antenna power specifically includes the following steps:

step 1, judging whether business information of the electronic equipment needs to be sent; if yes, the step 2 is carried out, and if not, the process is ended.

Step 2, judging whether the electronic equipment sends service data through Wi-Fi; if yes, performing the step 3, otherwise, performing the step 4;

and 3, periodically receiving the Wi-Fi data packets sent by the user.

And 4, sending service data through a data network, and periodically sending Wi-Fi data packets for radar detection.

Step 5, the electronic equipment judges whether the Wi-Fi data packet sent by the electronic equipment is successfully received or not; if yes, performing step 6; if not, go to step 9, send the service data.

Step 6, the electronic equipment receives the Wi-Fi data packet sent by the electronic equipment, extracts CSI information (such as frequency spectrum information and energy information), and analyzes the distance between the electronic equipment and a human body;

step 7, judging whether the distance is smaller than or equal to a preset distance threshold value D; if yes, performing step 8; if not, performing step 9, and sending service data;

step 8, reducing the maximum transmitting power;

and 9, sending the service data.

In the above example, under the condition that the electronic device is connected with the router, the distance between the electronic device and the human body can be analyzed and judged by extracting the CSI information of the Wi-Fi signal, so that Wi-Fi wireless sensing is realized. According to the method, the distance between the human body and the electronic equipment can be detected instead of the SAR sensor, and the influence of the electronic equipment on the human health is reduced. Compared with the existing SAR reduction technology, the SAR sensor reduction method has the advantages that the cost for deploying the SAR sensor can be reduced, and the space occupation of the SAR sensor on electronic equipment can be avoided.

Exemplary two

In this example two, the electronic device is not connected to a router.

Referring to fig. 3, the method for adjusting antenna power specifically includes the following steps:

Step 2, the electronic equipment sends service data through a data network and periodically sends Wi-Fi data packets at the same time;

step 3, the electronic equipment judges whether the Wi-Fi data packet sent by the electronic equipment is successfully received or not; if yes, performing step 4; if not, go to step 7.

Step 4, the electronic equipment receives the Wi-Fi data packet sent by the electronic equipment, extracts CSI information (such as frequency spectrum information and energy information), and analyzes the distance between the electronic equipment and a human body;

step 5, judging whether the distance is smaller than or equal to a preset distance threshold value D; if yes, performing step 6; if not, performing step 7;

step 6, reducing the maximum transmitting power;

and 7, sending the service data.

In the above example, in the case that the electronic device is not connected to the router, the service data is sent through the data network, and meanwhile, an additional Wi-Fi signal is periodically sent to sense the distance between the mobile phone and the human body, and the sent Wi-Fi signal does not cause any influence on normal services. The distance between the electronic equipment and the human body can be analyzed and judged by receiving the Wi-Fi signals sent by the user and extracting the CSI information in the Wi-Fi signals, so that the maximum transmitting power of the electronic equipment can be adjusted according to the distance. Therefore, the Wi-Fi signal can replace the SAR sensor to detect the distance between the human body and the electronic equipment, and the influence of the electronic equipment on the health of the human body can be reduced. Compared with the existing SAR reduction technology, the SAR sensor reduction method has the advantages that the cost for deploying the SAR sensor can be reduced, and the space occupation of the SAR sensor on electronic equipment can be avoided.

It is further noted that the posture and the motion of the human body can be sensed based on the detection signal, so that the distance between the human body and the electronic device can be more accurately judged.

During specific implementation, because different body parts have different tolerance degrees to electromagnetic radiation, by sensing the posture and the action of a human body, which parts of the human body are closest to the electronic equipment can be judged more accurately, and different maximum transmitting powers are set for different body parts. Therefore, the radiation performance of the antenna can be ensured to the maximum extent while the influence of electromagnetic radiation on human health is avoided.
