Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to fig. 1 to 9 in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The embodiment of the application provides an antenna control method, an antenna control device and electronic equipment. The main body of the antenna control method may be the antenna control device provided in this embodiment of the present application, or an electronic device integrated with the antenna control device, where the antenna control device may be implemented in a hardware or software manner, and the electronic device 100 may be a smart phone, a tablet computer, a palm computer, a notebook computer, or a desktop computer.

The antenna control apparatus or the electronic device may implement a wireless communication function. For example, a Wireless Fidelity (Wi-Fi) signal, a Global Positioning System (GPS) signal, a third Generation mobile communication technology (3G), a fourth Generation mobile communication technology (4G), a fifth Generation mobile communication technology (5G), a Near Field Communication (NFC) signal, a Bluetooth (BT) signal, an Ultra WideBand (UWB) signal, and the like may be transmitted.

Referring to fig. 1, fig. 1 is a first structural schematic diagram of an electronic device according to an embodiment of the present disclosure, where the antenna control method provided in the embodiment of the present disclosure may be applied to an electronic device 100, and the electronic device 100 may include a plurality of antennas, for example, a first antenna 110, a second antenna 120, and a third antenna 130, where a first distance D1 between the first antenna 110 and the second antenna 120 may be different from a second distance D2 between the first antenna 110 and the third antenna 130.

It is understood that the first distance D1 may be the shortest distance between the radiator in the first antenna 110 and the radiator in the second antenna 120; the second distance D2 may be the shortest distance between the radiator in the first antenna 110 and the radiator in the third antenna 130. The first distance D1 and the second distance D2 may be detected using the same measurement method.

Referring to fig. 2, fig. 2 is a first schematic flow chart of an antenna control method according to an embodiment of the present application, where the antenna control method according to the embodiment of the present application includes:

in 101, when an antenna power back-off event is triggered, acquiring operating states of a first antenna 110, a second antenna 120 and a third antenna 130;

when the electronic device 100 detects that the SAR value of the electronic device 100 exceeds the SAR value threshold, the electronic device 100 may trigger an antenna power back-off event indicating that the SAR value of the electronic device 100 exceeds the SAR value threshold.

It is understood that whether the SAR value of the electronic device 100 exceeds the SAR value threshold may be determined by obtaining a total transmission power of the electronic device 100, which may be a sum of transmission powers of antennas in an active state within the electronic device 100. For example, when the first antenna 110 and the second antenna 120 operate simultaneously, the total transmission power may be the sum of the transmission powers of the first antenna 110 and the second antenna 120; for another example, when the first antenna 110 and the third antenna 130 operate simultaneously, the total transmission power may be the sum of the transmission powers of the first antenna 110 and the third antenna 130.

After triggering the antenna power back-off event, the electronic device 100 needs to adjust the current transmission power of one or more antennas, so that when the total transmission power of the adjusted antennas is smaller than the SAR value threshold, the triggering of the antenna power back-off event is released. In the related art, the same antenna is usually backed off according to a preset back-off rule, for example, when the first antenna 110 transmits signals simultaneously with the second antenna 120 or the third antenna 130, the first antenna 110 is usually backed off according to the same back-off value. It is apparent that the backoff operation of the first antenna 110 is not flexible enough.

When an antenna power back-off event is triggered, the electronic device 100 of the embodiment of the application may acquire the operating states of the first antenna 110, the second antenna 120, and the third antenna 130. The operating state may be a transmission state of the first antenna 110, the second antenna 120, and the third antenna 130, and the electronic device 100 may obtain transmission power of the first antenna 110, the second antenna 120, and the third antenna 130 to obtain the transmission state of each antenna.

In 102, when the first antenna 110 and the second antenna 120 transmit wireless signals simultaneously, adjusting transmission parameters of the first antenna 110 according to a first backoff value;

in 103, when the first antenna 110 and the third antenna 130 transmit wireless signals simultaneously, the transmission parameter of the first antenna 110 is adjusted according to a second backoff value, which is different from the first backoff value.

As shown in fig. 1, the first distance D1 between the first antenna 110 and the second antenna 120 is different from the second distance D2 of the first antenna 110 and the third antenna 130. When the first antenna 110 and the second antenna 120 transmit wireless signals simultaneously, the electronic device 100 may adjust the transmission parameter of the first antenna 110 according to the first backoff value. For example, the current transmission power of the first antenna 110 is P0, and the first backoff value is P1, the electronic device 100 may adjust the current transmission power to P0 according to the first backoff value P1, and the adjusted transmission power P of the first antenna 110_{Tune 1}After the first antenna 110 performs the backoff operation, the electronic device 100 may release the antenna power backoff event.

When the first antenna 110 and the third antenna 130 transmit wireless signals simultaneously, the electronic device 100 may adjust the transmission parameter of the first antenna 110 according to a second backoff value, which may be different from the first backoff value. For example, the current transmission power of the first antenna 110 is P0, and the second backoff value is P2, the electronic device 100 may adjust the current transmission power according to the second backoff value P2, and the adjusted transmission power P of the first antenna 110_{Tune 2}After the first antenna 110 performs the retraction operation, the electronic device 100 may release the transmissionAn antenna power back-off event.

It is understood that the first backoff value is not a certain value for the first antenna 110. For example, the electronic device 100 needs to reduce the SAR value by a certain magnitude, and then all backoff values that satisfy the reduction of the SAR value are all satisfactory, and the electronic device 100 may select an adaptive backoff value as the first backoff value according to the performance of the first antenna 110. That is, a backoff rule may be preset in the electronic device 100, so that the first antenna 110 may determine the first backoff value according to the backoff rule. Similarly, the second back-off value is not a fixed value, and another back-off rule may be preset inside the electronic device 100, so that the first antenna 110 may determine the second back-off value according to the back-off rule.

It should be noted that, in the related art, for the first antenna 110, the electronic device 100 does not distinguish the situation of other antennas that are concurrent with the first antenna 110, and performs the back-off operation on the first antenna 110 directly by using the same set of back-off rules, so that the back-off control of the first antenna 110 is not flexible.

It can be understood that, since the first backoff value is different from the second backoff value, the transmit power P after the backoff operation of the first antenna 110 is performed according to the first backoff value_{Tune 1}Different from the transmission power P of the first antenna 110 after the back-off operation according to the second back-off value P2_{Tune 2}Thus, when the first antenna 110 is transmitting simultaneously with other antennas, the first antenna 110 may select different power back-off values depending on the antenna transmitting simultaneously with it.

In the antenna control method according to the embodiment of the present application, a first distance D1 between the first antenna 110 and the second antenna 120 of the electronic device 100 is different from a second distance D2 between the first antenna 110 and the third antenna 130, and the antenna control method includes: acquiring the working states of the first antenna 110, the second antenna 120 and the third antenna 130 when an antenna power backoff event is triggered; when the first antenna 110 and the second antenna 120 transmit wireless signals simultaneously, adjusting the transmission parameters of the first antenna 110 according to the first backoff value; when the first antenna 110 and the third antenna 130 transmit wireless signals simultaneously, the transmission parameters of the first antenna 110 are adjusted according to a second backoff value, which is different from the first backoff value. Based on this, in the antenna control method according to the embodiment of the present application, when the first antenna 110 and the second antenna 120 or the third antenna 130 transmit simultaneously, the first antenna 110 may select different backoff values to perform power backoff operations, and the electronic device 100 may classify application scenarios of the first antenna 110 and classify backoff values of the first antenna 110, so that the backoff operations of the first antenna 110 are more flexible, the first antenna 110 may select a backoff value more suitable for the application scenarios, and the antenna performance of the first antenna 110 is better.

After obtaining the working states of the first antenna 110, the second antenna 120, and the third antenna 130, the antenna control method may further include: determining whether the first distance D1 is greater than the second distance D2; if so, controlling the first antenna 110 and the second antenna 120 to simultaneously transmit wireless signals, and adjusting the transmission parameters of the first antenna 110 according to a first backoff value, wherein the first backoff value is smaller than a second backoff value; if not, the first antenna 110 and the third antenna 130 are controlled to simultaneously transmit wireless signals, and the transmission parameters of the first antenna 110 are adjusted according to a second backoff value, where the second backoff value is smaller than the first backoff value.

When the first antenna 110 and the second antenna 120 simultaneously transmit signals and the first antenna 110 is backed off according to the first back-off value, the antenna control method may further include: and adjusting the transmission parameters of the second antenna 120 according to the third backoff value, so that the adjusted first antenna 110 and the second antenna 120 can release the trigger of the antenna power backoff event.

When the first antenna 110 and the third antenna 130 transmit signals simultaneously and the first antenna 110 is backed off according to the second back-off value, the antenna control method may further include: and adjusting the transmission parameter of the third antenna 130 according to the fourth backoff value, so that the adjusted first antenna 110 and the third antenna 130 can release the trigger of the antenna power backoff event.

Based on the above description, an embodiment of the present application further provides an antenna control method, please refer to fig. 3 and fig. 4 in combination with fig. 1, where fig. 3 is a schematic diagram of a second structure of the electronic device provided in the embodiment of the present application, and fig. 4 is a schematic diagram of a second flow of the antenna control method provided in the embodiment of the present application.

In 201, when an antenna power back-off event is triggered, acquiring the operating states of the first antenna 110, the second antenna 120, and the third antenna 130;

when an antenna power back-off event is triggered, the electronic device 100 of the embodiment of the application may acquire the operating states of the first antenna 110, the second antenna 120, and the third antenna 130. The operation state may be a transmission state of the first antenna 110, the second antenna 120, and the third antenna 130.

At 202, determine whether the first distance D1 is greater than the second distance D2;

in 203, if so, the first antenna 110 and the second antenna 120 are controlled to simultaneously transmit wireless signals, and the transmission parameters of the first antenna 110 are adjusted according to a first backoff value, where the first backoff value is smaller than the second backoff value.

As shown in fig. 3, when the first distance D1 between the first antenna 110 and the second antenna 120 is greater than the second distance D2 between the first antenna 110 and the third antenna 130, the distance between the first antenna 110 and the second antenna 120 is farther. When a user holds the electronic device 100, the SAR value generated by the signals transmitted by the first antenna 110 and the second antenna 120 at the same time may be smaller than the SAR value generated by the signals transmitted by the first antenna 110 and the third antenna 130 at the same time, and at this time, the first backoff value generated by the signals transmitted by the first antenna 110 and the second antenna 120 at the same time may be smaller than the second backoff value generated by the signals transmitted by the first antenna 110 and the third antenna 130 at the same time, so that the SAR value of the electronic device 100 may be reduced after the first antenna 110 is backed according to the first backoff value, and the power of the electronic device 100 after the first antenna is backed is kept at a larger value, thereby improving the radiation performance of the first antenna 110.

At 204, adjusting the transmission parameter of the second antenna 120 according to the third backoff value, so that the adjusted first antenna 110 and the second antenna 120 can release the trigger of the antenna power backoff event;

when the first antenna 110 and the second antenna 120 transmit signals simultaneously, except forIn addition to performing the backoff operation on the first antenna 110 according to the first backoff value, the second antenna 120 may also perform the backoff operation according to the third backoff value. For example, the current transmit power of the second antenna 120 is P_0-2And the third backoff value is P3, the electronic device 100 may determine the current transmission power to be P3 according to the third backoff value_0-2Adjusting the adjusted transmitting power P of the second antenna 120_{Tune 3}＝P_0-2-P3. The first antenna 110 and the second antenna 120 perform the back-off operation simultaneously, so as to prevent the first antenna 110 from backing off a large power to affect the radiation performance of the first antenna 110.

It is understood that the third backoff value may be the same as or different from the first backoff value. The third backoff value may be set as required, so that the SAR value of the electronic device 100 may meet requirements after the first antenna 110 and the second antenna 120 operate according to the first backoff value and the third backoff value, and the antenna power backoff event may be released from being triggered.

In 205, if not, controlling the first antenna 110 and the third antenna 130 to simultaneously transmit the wireless signal, and adjusting the transmission parameter of the first antenna 110 according to a second backoff value, where the second backoff value is smaller than the first backoff value;

as shown in fig. 1, a first distance D1 between the first antenna 110 and the second antenna 120 may be smaller than a second distance D2 between the first antenna 110 and the third antenna 130, and the distance between the first antenna 110 and the third antenna 130 is further, at this time, a second backoff value when the first antenna 110 and the third antenna 130 transmit simultaneously may be smaller than a first backoff value when the first antenna 110 and the second antenna 120 transmit simultaneously, so that the SAR value of the electronic device 100 may be reduced after the first antenna 110 backs down according to the second backoff value, and the power after the first antenna 110 backs down may also be kept at a larger value, thereby improving the radiation performance of the first antenna 110.

At 206, the transmission parameters of the third antenna 130 are adjusted according to the fourth backoff value, so that the adjusted first antenna 110 and the third antenna 130 can release the trigger of the antenna power backoff event.

When the first antenna 110 and the third antenna 130 transmit signals simultaneously, in addition to the first antenna 110 performing the backoff operation according to the second backoff value, the third antenna 130 may also perform the backoff operation according to the fourth backoff value, and for the specific operation, reference may be made to the second antenna 120 performing the backoff operation according to the third backoff value, which is not described in detail herein. The first antenna 110 and the third antenna 130 perform the back-off operation simultaneously, so as to prevent the first antenna 110 from backing off a large power to affect the radiation performance of the first antenna 110.

It is understood that the fourth backoff value may be the same as or different from the second backoff value. The fourth backoff value may be set as required, so that the SAR value of the electronic device 100 may release the trigger of the antenna power backoff event when the SAR value of the electronic device 100 may radiate the requirement after the first antenna 110 and the third antenna 130 operate according to the second backoff value and the fourth backoff value.

In the antenna control method according to the embodiment of the application, the electronic device 100 sets the first backoff value and the second backoff value according to the first distance D1 and the second distance D2, the first antenna 110 may select different backoff values according to the first distance D1 from the second antenna 120 and the second distance D2 from the third antenna 130, and the first antenna 110 may select a smaller backoff value for performing a backoff operation, so that the SAR of the electronic device 100 may be reduced, and the antenna performance of the first antenna may be ensured.

Wherein the first antenna 110 may be a first type of antenna, and the second antenna 120 and the third antenna 130 may be a second type of antenna. The first type may be a Wireless Local Area Network (WLAN) system, the first antenna 110 may be a WLAN system antenna, and the first antenna 110 may be a Wi-Fi antenna, for example. The second type may be a Wireless Wide Area Network (WWAN) format, and the second antenna 120 and the third antenna 130 may be antennas of the WWAN format, for example, the second antenna 120 and the third antenna 130 may be cellular antennas.

It can be understood that, referring to fig. 5, fig. 5 is a schematic structural diagram of a third electronic device 100 according to an embodiment of the present application. When the first antenna 110 is a Wi-Fi antenna, and the second antenna 120 and the third antenna 130 are cellular antennas, the electronic device 100 may include the processor 10 and the switch module 140, and the processor 10 may control the switch module 140 to be turned on to control the first antenna 110 and the second antenna 120 to simultaneously transmit Wi-Fi and cellular signals, or control the first antenna 110 and the third antenna 130 to simultaneously transmit Wi-Fi and cellular signals.

It is understood that, as shown in fig. 1, the first antenna 110 and the second antenna 120 may be disposed at the top of the electronic device 100, and the third antenna 130 may be disposed at the bottom of the electronic device 100, when the user holds the electronic device 100, the first antenna 110 and the second antenna 120 are close to the ear of the person, the first antenna 110 and the second antenna 120 are closer to the head of the user, and the SAR value is higher; at this time, the electronic device 100 may control the first antenna 110 and the third antenna 130 to simultaneously transmit the wireless signal to reduce the SAR value of the electronic device 100. And, the electronic device 100 may control the first antenna 110 to perform the backoff operation with a second smaller backoff value to ensure the radiation performance of the first antenna 110.

The first antenna 110 may include one or more antenna radiators, and the second antenna 120 and the third antenna 130 may also include one or more antenna radiators. The first back-off value or the second back-off value of the plurality of antenna radiators included in the first antenna 110 may be different or partially the same, that is, different antenna radiators may have different or at least partially the same first back-off value and second back-off value. Similarly, the third back-off value or the fourth back-off value of the plurality of antenna radiators included in the second antenna 120 or the third antenna 130 may be different or at least partially the same.

It can be understood that, when the first antenna 110 and the second antenna 120 transmit wireless signals simultaneously, if the sum of the numbers of radiators of the first antenna 110 and the second antenna 120 is three or more, the electronic device 100 may select an antenna radiator with a minimum first backoff value from the multiple antenna radiators of the first antenna 110, and select an antenna radiator with a minimum third backoff value from the multiple antenna radiators of the second antenna 120 to perform a backoff operation together, so that after the backoff operation, the SAR values of the first antenna 110 and the second antenna 120 are small and can contact a trigger event of antenna power. Similarly, when the first antenna 110 and the third antenna 130 transmit wireless signals simultaneously, if the sum of the numbers of the radiators of the first antenna 110 and the third antenna 130 is three or more, the electronic device 100 may select an antenna radiator with the smallest first backoff value from the multiple antenna radiators of the first antenna 110, and select an antenna radiator with the smallest fourth backoff value from the multiple antenna radiators of the third antenna 130 to perform a backoff operation together, so that the SAR values of the first antenna 110 and the third antenna 130 after the backoff operation are small and can contact a trigger event of the antenna power.

It can be understood that, since the distances between the plurality of antenna radiators of the second antenna 120 and the first antenna 110 are substantially the same, the backoff operations may be performed according to the first backoff value when the different antenna radiators in the first antenna 110 and the second antenna 120 transmit the wireless signals. Similarly, since the distances between the plurality of antenna radiators of the third antenna 130 and the first antenna 110 are also substantially the same, the backoff operation may be performed according to the second backoff value when the different antenna radiators in the first antenna 110 and the third antenna 130 transmit the wireless signal.
