Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an antenna power adjustment method and apparatus. Background Technology

[0002] With the increasing functionality of electronic devices, the growing variety of sensors used, and the proliferation of wireless technologies employed, the impact of electromagnetic radiation generated during device use on human health has become a growing public concern, especially with the evolution of wireless communication devices like smartphones. To ensure the safe operation of wireless communication devices and protect the interests of users, governments and telecommunications regulatory bodies worldwide have stipulated that electromagnetic radiation must meet safety standards before being put into use; this is known as SAR (Specific Absorption Rate). SAR is the ratio of electromagnetic wave energy absorbed by wireless products such as mobile phones.

[0003] Currently, SAR sensors are deployed in electronic devices to detect human proximity and adjust the power of the devices accordingly, thereby reducing the absorption of electromagnetic energy by the human body. However, this method not only requires additional hardware costs but also occupies more space in the electronic devices, impacting antenna layout. Summary of the Invention

[0024] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0025] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0026] The antenna power adjustment method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0027] See Figure 1 This application provides an antenna power adjustment method, applied to electronic devices, specifically including the following steps:

[0028] Step 101: If it is determined that service data needs to be sent, send a wireless probe signal;

[0029] The wireless detection signals include Wi-Fi signals or Bluetooth signals.

[0030] In one specific implementation, when the electronic device transmits the service data through a data network, the wireless detection signal is a Wi-Fi signal;

[0031] In this method, when the electronic device is not connected to the router, the service data is transmitted through the data network, and Wi-Fi data packets are periodically sent for radar to detect the distance between the electronic device and the human body. When the electronic device is connected to the router, the electronic device sends service data through Wi-Fi signals or the data network. If the electronic device sends service data through the data network, the electronic device needs to send Wi-Fi data packets at the same time for radar to detect the distance between the electronic device and the human body.

[0032] In another specific implementation, when the electronic device is connected to the router and transmits the service data via Wi-Fi signal, the wireless detection signal is a Wi-Fi signal used to transmit the service data.

[0033] In this method, when the electronic device is connected to the router, if the electronic device sends service data via Wi-Fi signal, there is no need to send additional Wi-Fi signals for radar detection. The distance between the electronic device and the human body can be detected by using the Wi-Fi signal that sends service data.

[0034] It should be noted that when electronic devices do not need to transmit service data, they do not need to emit signals through their antennas. In this case, the antenna's impact on the human body is minimal, thus eliminating the need to initiate the SAR reduction process. Therefore, when electronic devices are transmitting service information, they send wireless detection signals to determine the distance between the electronic device and the human body based on the reflected signals. If no service data is being transmitted, the SAR reduction process is not initiated, meaning no detection signal is required.

[0035] Step 102: Receive the reflected signal of the wireless detection signal;

[0036] It should be noted that when the detection signal sent by the electronic device encounters a human body or other obstacle, the detection signal will be reflected back to the electronic device. If the strength of the reflected signal received by the electronic device is lower than the receiving sensitivity, it will not be able to successfully receive the detection signal it sent. If the strength of the received reflected signal is greater than or equal to the receiving sensitivity, it will be able to successfully receive the detection signal it sent.

[0037] For example, when an electronic device transmits business data via Wi-Fi signal, the electronic device can periodically (which can be flexibly set, such as T=1min) receive a Wi-Fi data packet that it sends and reflects back. Receiving the Wi-Fi data packet that it sends and reflects back is used to detect the distance between the electronic device and the human body.

[0038] Step 103: Adjust the maximum transmission power of the antenna according to the reflected signal; the antenna is used to transmit the service data.

[0039] For example, the correspondence between different reflected signal intensities and distances can be obtained in advance through experiments. Based on this correspondence, the distance corresponding to the received reflected signal intensity can be determined, thereby obtaining the distance between the electronic device and the human body. The maximum transmission power of the antenna can be adjusted based on this distance.

[0040] For example, the distance between an electronic device and a human body can be determined based on the Channel State Information (CSI) of the reflected signal, and the maximum transmit power of the antenna can be adjusted based on this distance.

[0041] For example, the distance between the electronic device and the human body can be determined based on the round-trip time of the detected and reflected signals and the propagation speed of the signals, and the maximum transmit power of the antenna can be adjusted based on this distance.

[0042] In the above embodiments, the electronic device sends a wireless detection signal when it determines that service data needs to be transmitted; and based on the reflected signal of the received detection signal, the distance between the electronic device and the human body can be detected, thereby adjusting the maximum transmission power of the antenna based on the detected distance. Compared with the prior art, this not only avoids the space occupied by SAR sensors on the electronic device, but also reduces the cost of deploying SAR sensors.

[0043] In a specific embodiment of this application, adjusting the maximum transmit power of the antenna based on the reflected signal includes:

[0044] Based on the signal energy and spectral characteristics of the Channel State Information (CSI) corresponding to the reflected signal, determine whether the distance between the electronic device and the human body is less than or equal to a preset distance threshold;

[0045] When the distance between the electronic device and the human body is less than or equal to a preset distance threshold, the maximum transmission power of the antenna is reduced.

[0046] In a specific embodiment of this application, determining whether the distance between the electronic device and the human body is less than a preset distance threshold based on the signal energy and spectral characteristics of the Channel State Information (CSI) corresponding to the reflected signal includes:

[0047] Based on the signal energy and spectral characteristics of CSI, determine whether the reflected signal is a human body reflected signal;

[0048] If the reflected signal is a human body reflected signal, and the signal energy is greater than the energy threshold, then it is determined that the distance between the electronic device and the human body is less than the preset distance threshold.

[0049] In practice, the spectral characteristics and signal energy of the CSI information corresponding to the detected signal reflected by a human body and the reflected signal reflected by an object differ significantly. Therefore, signal processing can be performed on the CSI information of the reflected signal to obtain the spectral characteristics and signal energy of the CSI. Furthermore, a machine learning model can be used to distinguish the spectral characteristics and signal energy corresponding to the reflected signals reflected by a human body and the reflected signals reflected by an object. In this way, it can be determined whether the reflected signal is a human body reflected signal based on the signal energy and spectral characteristics of the CSI.

[0050] Furthermore, since the greater the energy of CSI, the farther the electronic device is from the human body, the smaller the energy of the CSI of the received reflected signal; if the energy of the CSI of the reflected signal is greater than the threshold W (energy threshold), it is determined that the distance between the electronic device and the human body is less than the threshold D (preset distance threshold); 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).

[0051] In a specific embodiment of this application, 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:

[0052] When the distance between the electronic device and the human body is less than or equal to the preset distance threshold, the target distance range corresponding to the distance is determined;

[0053] Based on the preset correspondence between the distance range and the maximum transmission power, the target maximum transmission power corresponding to the target distance range is determined;

[0054] Reduce the maximum transmit power of the antenna to the maximum transmit power of the target.

[0055] The maximum transmission power varies depending on the distance range.

[0056] Understandably, to avoid impacting human health, the smaller the distance, the lower the maximum transmission power.

[0057] In this embodiment, a specific reduction in maximum transmit power is assigned to each distance interval (distance range). For example, the distance range of 0 to 1 meter is divided into distance interval a (e.g., 0 to 0.3 meters), distance interval b (e.g., 0.3 to 0.6 meters), and distance interval c (0.6 to 1 meter). Distance interval a corresponds to a first maximum power value, distance interval b corresponds to a second maximum power value, and distance interval c corresponds to a third maximum power value, with the first maximum power value < the second maximum power value < the third maximum power value. In this way, the maximum transmit power of the antenna can be gradually reduced, thus maximizing the antenna's radiation performance while avoiding any impact on human health.

[0058] The antenna power adjustment method of this application will be explained below using Wi-Fi signal as a detection signal as an example.

[0059] Example 1

[0060] In this example, the electronic device is connected to the router.

[0061] See Figure 2 The antenna power adjustment method specifically includes the following steps:

[0062] Step 1: Determine if the electronic device has any service information to send; if yes, proceed to Step 2; otherwise, end the process.

[0063] Step 2: Determine whether the electronic device is sending service data via Wi-Fi; if yes, proceed to Step 3; otherwise, proceed to Step 4.

[0064] Step 3: Periodically receive the Wi-Fi data packets you send.

[0065] Step 4: Send business data through the data network, and periodically send Wi-Fi data packets for radar detection.

[0066] Step 5: The electronic device determines whether it has successfully received the Wi-Fi data packet it sent; if yes, proceed to step 6; if no, proceed to step 9 to send service data.

[0067] Step 6: The electronic device receives the Wi-Fi data packets it sends and extracts CSI information (such as spectrum information and energy information) to analyze the distance between the electronic device and the human body;

[0068] Step 7: Determine if the distance is less than or equal to the preset distance threshold D; if yes, proceed to step 8; if no, proceed to step 9: send service data.

[0069] Step 8: Reduce maximum transmit power;

[0070] Step 9: Send business data.

[0071] In the example above, when the electronic device is connected to a router, the distance between the electronic device and the human body can be analyzed and determined by extracting the CSI information of the Wi-Fi signal, thus achieving Wi-Fi wireless sensing. This example can replace SAR sensors to detect the distance between the human body and electronic devices, reducing the impact of electronic devices on human health. Compared with existing SAR reduction technologies, it not only reduces the cost of deploying SAR sensors but also avoids the space occupied by SAR sensors on electronic devices.

[0072] Example 2

[0073] In this second example, the electronic device is not connected to the router.

[0074] See Figure 3 The antenna power adjustment method specifically includes the following steps:

[0075] Step 1: Determine if the electronic device has any service information to send; if yes, proceed to Step 2; otherwise, end the process.

[0076] Step 2: The electronic device sends service data through the data network and periodically sends Wi-Fi data packets.

[0077] Step 3: The electronic device determines whether it has successfully received the Wi-Fi data packet it sent; if yes, proceed to step 4; if no, proceed to step 7.

[0078] Step 4: The electronic device receives the Wi-Fi data packets it sends and extracts CSI information (such as spectrum information and energy information) to analyze the distance between the electronic device and the human body;

[0079] Step 5: Determine if the distance is less than or equal to the preset distance threshold D; if yes, proceed to step 6; if no, proceed to step 7.

[0080] Step 6: Reduce maximum transmit power;

[0081] Step 7: Send business data.

[0082] In the example above, when the electronic device is not connected to the router, service data is transmitted via the data network. Simultaneously, additional Wi-Fi signals are periodically transmitted to sense the distance between the phone and the user, and these Wi-Fi signals do not affect normal service. By receiving the transmitted Wi-Fi signals and extracting the CSI information from them, the distance between the electronic device and the user can be analyzed, allowing for adjustments to the maximum transmission power of the electronic device. Therefore, this example demonstrates how to use Wi-Fi signals to replace SAR sensors in detecting the distance between the user and electronic devices, reducing the impact of electronic devices on human health. Compared to existing SAR reduction technologies, this not only reduces the cost of deploying SAR sensors but also avoids the space occupied by SAR sensors on electronic devices.

[0083] It should be further noted that the human body's posture and movements can be perceived based on the detection signals, thereby more accurately determining the distance between the human body and electronic devices.

[0084] In practice, since different body parts have varying tolerances to electromagnetic radiation, by sensing the body's posture and movements, it's possible to more accurately determine which parts of the body are closest to electronic devices and set different maximum transmission power for each part. This allows for maximizing antenna radiation performance while minimizing the impact of electromagnetic radiation on human health.
