detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1 , FIG. 1 is a flowchart of a method for adjusting transmit power provided by an embodiment of the present invention, which is applied to an electronic device with M antennas, where M is an integer greater than 1. As shown in Figure 1, the method for adjusting the transmission power includes the following steps:

Step 101. When the electronic device is in a wireless connection state, receive a first input from a user on the electronic device, and an area corresponding to the first input is an input area.

Wherein, the wireless connection state includes a wireless data connection state and a call connection state, wherein the wireless data connection state may include a network connection state, such as a state when an electronic device accesses a network. The call connection state may include a voice call state and a video call state, for example, a call state during a phone call or a state of a voice call through social software.

When the electronic device is in a wireless connection state, the antenna of the electronic device is in a signal transmitting state. Since the radiation generated when the antenna transmits signals has an impact on human health, when the user holds the electronic device, the area held by the user can be detected. The aforementioned input area may include an area held by the user, and may also include an area operated by the user. Specifically, a touch detection area can be set on the back and side of the electronic device, so as to detect the user's input through the touch detection area, thereby determining that the user is holding the electronic device.

Step 102. Determine a target antenna corresponding to the input area, where the target antenna is at least one of the M antennas.

The electronic device may preset a preset corresponding relationship between areas and antennas, one antenna may correspond to one or more areas, and one area may also correspond to one or more antennas.

The target antenna corresponding to the input area can be determined according to the above preset correspondence relationship.

Step 103, reducing the transmit power of the target antenna.

In this step, the transmission power of the target antenna is reduced to a preset value, so that the target antenna can transmit signals, and the transmission power is low, which can reduce radiation, and the antennas other than the target antenna are not processed. It is also possible to control the target antenna to stop transmitting according to the actual scene, so that the electronic device transmits signals through other antennas except the target antenna, so as to reduce the radiation to the human body.

Optionally, the side area of the electronic device includes a touch recognition area; the receiving the user's first input to the electronic device includes:

A first input from a user to the electronic device is received, and an input area of the first input is located in the touch recognition area.

In this embodiment, the side area of the electronic device includes a touch recognition area, and the screen of the electronic device may be a curved screen, a surround screen, a waterfall screen or the like. When the user holds the side area of the electronic device, the touch recognition area of the electronic device can identify the area held or operated by the user, that is, the input area. The above-mentioned side area may also include the upper and lower borders of the electronic device, which can detect the input area touched by the user's ear or face when making a voice call. Since the side area is relatively close to the area where the antennas are distributed, establishing a mapping relationship between the side area and the antenna can improve the accuracy of antenna determination and reduce radiation to users.

Optionally, before the determination of the target antenna corresponding to the input area, the method further includes: dividing the touch recognition area of the electronic device into N areas, where N is an integer greater than 1; establishing the A mapping relationship between the M antennas and the N areas.

In this implementation manner, the touch recognition area may be divided into N areas first. For example, as shown in Figure 2, the touch recognition area of the electronic device is divided into the left area (including left 1, left 2, left 3, left 4 and left 5), the right area (including right 1, right 2, Right 3, Right 4 and Right 5), the top area (including top 1) and the bottom area (including bottom 1). It should be noted that the schematic diagram shown in FIG. 2 is only for ease of understanding, and the touch recognition area may include an edge area and a side area of the display screen, and may also include an edge area on the back. During specific implementation, the area may be divided according to the location of the antenna and the location of the user's touch operation.

Then, according to the positional relationship between the antennas and the divided areas, the mapping relationship between the M antennas and the N areas can be established, for example, the mapping relationship between the antenna 1 and the area right 1, right 2, and top 1 is established; The mapping relationship between right 4 and right 5; establishing a mapping relationship between antenna 4 and left 5, right 5 and bottom 1, etc., is just an example here.

In addition, M antennas may be mapped to N areas by acquiring the area where each antenna is located.

In this way, according to the input received, the coordinate position of the input can be determined, thereby determining the area where the input is located. An antenna that needs to be reduced in power can be determined according to the area, so that the transmission power of the antenna can be reduced, and the accuracy of determining the antenna can be improved.

Optionally, the establishment of the mapping relationship between the M antennas and the N areas includes: according to the orthographic projection area and radiation direction of each of the M antennas on the electronic device . At least one item in the radiation pattern, establishing a mapping relationship between each antenna and the N areas.

In this embodiment, the corresponding area of each antenna on the electronic device may be determined according to any one or more items of the antenna's orthographic projection position on the electronic device, radiation direction, and radiation pattern.

For example, a mapping relationship is established between the projected area of the physical size of the antenna on the back of the electronic device and the divided N areas. The mapping relationship can be determined based on the touch sensing area where the orthographic projection of the physical size of the rear antenna toward the screen falls. When the orthographic projection area corresponding to the physical size of the antenna 1 falls into the touch areas Right 1, Right 2, and Top 1, the mapping relationship between the antenna 1 and the areas Right 1, Right 2, and Top 1 is established.

The touch area corresponding to the antenna may also be further determined in combination with the radiation direction and the field pattern of the antenna, that is, the area in the aforementioned N areas. For example, when the physical projection area of antenna 1 falls into the right 1 area, but the radiation field strength is strong in the right 1, right 2, and top 1 areas, you can associate right 1, right 2, top 1, and antenna 1, When the right 1, right 2, and top 1 receive input, it is considered that the antenna 1 is close to the human body, and the transmission power of the antenna 1 is reduced.

In this way, determining the touch area corresponding to the antenna based on multiple aspects of the antenna can improve the accuracy of determining the antenna and reduce radiation to the human body.

Optionally, when the electronic device is in the wireless data connection state, the input area includes a top area of the electronic device and other areas of the electronic device;

The reducing the transmit power of the target antenna includes:

reducing the transmit power of the second target antenna among the target antennas, keeping the transmit power of the first target antenna among the target antennas unchanged;

Wherein, the first target antenna is the antenna corresponding to the top area, and the second target antenna is the target antenna corresponding to the other areas, and the other areas do not include the top area.

Wherein, the wireless data connection state may be a data connection state, and in this state, the electronic device can access network data, or perform data transmission with other electronic devices, for example, send data, receive data, download files, and so on.

When the electronic device is in a state of wireless data connection, the electronic device may reduce the transmitting power of the target antenna according to the user's holding state. When the target antenna includes an antenna located in the top area, the transmission power of the antenna in the top area is controlled to remain unchanged, and the transmission power of the antenna in other areas is reduced. The other areas can be in the touch detection area of the electronic device, except for the top area. outside area.

The electronic device may include a top area and a bottom area opposite to each other, wherein the screen corresponding to the top area of the electronic device is usually used to display information such as time, signal, and power.

When the electronic device is in the above wireless data connection state, the electronic device is usually mainly handheld, because when the electronic device is handheld, the transmitting antenna is often switched to the top. Therefore, keep the transmit power of the top area unchanged, and adjust other target antennas, so that the wireless performance of the user in use will not be affected.

In this way, when the electronic device is in the wireless data connection state and the user holds the electronic device, the transmission power of the antenna in the top area can be maintained, while the signal transmission power of the antennas in other areas can be reduced. The radiation to the user can be reduced, and the signal emission effect of the electronic equipment can be improved.

In addition, when the electronic device is in a voice or video call state, it can be adjusted according to the actual situation. For example, when the electronic device is in a voice call, the antenna mapped to the top area of the electronic device is searched according to the input area, and the transmission power of the antenna in the top area is reduced; In the middle, and when the electronic device is tilted and in a talking state, if the touch area does not include the bottom area, the maximum power transmission of the bottom antenna can still be maintained. For the bottom of the handheld electronic device, but when the touch area does not involve the top area, for example, the handheld electronic device is in hands-free mode or voice input mode, the maximum power transmission of the antenna in the top area can still be maintained.

In order to facilitate understanding of the embodiments of the present invention, examples are given below in conjunction with specific implementations. As shown in Figure 3, the adjustment method of transmit power includes:

Step 301 , when the electronic device establishes a wireless connection, acquire the coordinates of the touch screen that has received an input, and confirm whether it falls within a pre-divided area according to the coordinate points.

In this step, through the received coordinates of the touch screen, it can be determined whether the coordinates of the touch screen are located in the preset touch area range, such as the area near the antenna or the touch screen on the side of the electronic device area.

Step 302, when the coordinate point is located in a pre-divided area, index to the corresponding antenna according to the area code.

In this step, the area where the touch screen coordinates are located is the input area corresponding to the first input. Step 303. Set the limit of the maximum transmit power of the antenna to a predetermined value.

In this step, the maximum transmit power of the antenna is reduced to a preset range.

It can fully monitor the state of the transmitting antenna being approached by the human body without additional sensors, so as to reduce the SAR of the antenna in a targeted manner.
