[0001] This application relates to the technical field of controlling antenna radiation, and more particularly to a control method and electronic device. Background Technology

[0002] Currently, regardless of the operating mode, the power amplifier of an electronic device transmits radiated signals at the same power. This makes the antenna unable to adapt to its specific operating environment. In certain antenna operating scenarios, the consistent power output of the radiated signal can degrade its performance, making it difficult for the base station to demodulate the signal. This can affect the throughput of the electronic device, leading to reduced throughput and even network outages. Summary of the Invention

[0017] If the second parameter is less than the second threshold, the system switches from the first antenna operating mode to the second antenna operating mode. The second parameter being less than the second threshold indicates that the transmission performance of the target antenna does not meet the requirements of the base station.

[0031] This application provides a control method applicable to electronic devices for controlling the radiation performance of antennas. The electronic device can refer to various devices such as smartphones, tablets, and laptops; this application does not limit the specific type of electronic device, as long as the electronic device has a target antenna 302.

[0032] like Figure 1 As shown, the control method includes steps S101 and S102.

[0033] Step S101: In response to the target instruction in the target scenario, determine the target working mode.

[0034] Optionally, the aforementioned target scenario can be understood as the scenario in which the target antenna 302 is located, and the target scenario may be related to the radiation performance and reception performance of the target antenna 302.

[0035] For example, when the radiation performance and reception performance of the target antenna 302 are relatively balanced, it can be determined that the electronic device is in a first target scenario, and at this time, the electronic device can generate a first target command; when the radiation performance of the target antenna 302 is poor, it can be determined that the electronic device is in a second target scenario, and at this time, the electronic device can generate a second target command; when the reception performance of the target antenna 302 is poor, it can be determined that the electronic device is in a third target scenario, and at this time, the electronic device can generate a third target command.

[0036] Therefore, the scene in which the target antenna 302 is located can be directly determined based on the radiation and reception performance of the target antenna 302, and instructions can be generated based on this to determine the target working mode of the target antenna 302 to adapt to the current scene.

[0037] Step S102: Control the target antenna 302 in the target operating mode to receive a first radiated signal at a first frequency, and simultaneously transmit a second radiated signal at a second frequency; the first frequency and the second frequency belong to the same frequency band. The target operating mode includes multiple different antenna operating modes, and at least two of these modes transmit the second radiated signal at a second frequency with different target powers. The target power characterizes the power of the radio frequency path between the antenna port of the target antenna 302 and the transceiver 202, ensuring that the transmit power in different antenna operating modes is equal to or approaches the power limit of the target scenario.

[0038] Optionally, the aforementioned target power can be understood as the conducted target power of the antenna. The transmitted power of the antenna is the sum of the conducted target power and the radiation gain. By changing the conducted target power, the transmitted power of the antenna can be adjusted, thereby achieving the purpose of adjusting the radiation performance of the antenna.

[0039] Optionally, the electronic device employing the above control method may include a power amplifier 203. The target power can be understood as the operating limit power of the power amplifier 203, that is, the power amplifier 203 operates at a power value less than or equal to the target power, which can increase the signal gain to a high power level without reducing the signal quality. In this application, the target power of the power amplifier 203 is different in different antenna operating modes. This ensures that the maximum transmission power that the power amplifier 203 can operate in the target scenario under different antenna operating modes is equal to or close to the limit power of the target scenario, so as to maximize the transmission power of the antenna and effectively improve the radiation performance of the antenna.

[0040] Optionally, the target scenario may include at least objects subject to electromagnetic radiation restriction and objects subject to electromagnetic radiation restriction. For example, if the target scenario in which the electronic device is located includes objects such as the human body that cannot absorb excessive electromagnetic radiation energy, then the target scenario can be determined to include objects subject to electromagnetic radiation restriction.

[0041] When the target scenario includes objects subject to electromagnetic radiation restriction, the corresponding restriction power can be determined. The restriction power can be understood as the Specific Absorption Ratio (SAR), a parameter that measures the electromagnetic radiation energy absorbed by the human body. When an electronic device approaches a human body, the transmission power of the second radiation signal emitted by the electronic device cannot exceed the SAR, i.e., it cannot exceed the restriction power, in order to protect the human body.

[0042] Optionally, the transmit power being equal to or approaching the limit power of the target scenario under different antenna operating modes can be understood as the transmit power of the antenna being less than or equal to the limit power of the target scenario, thus avoiding the problem of excessive radiation.

[0043] Optionally, a configuration table can be set for the antenna operating mode under different target scenarios. The configuration table can be stored in the processor 101 of the electronic device, and the processor 101 can call the configuration table when determining the antenna operating mode. There can be multiple configuration tables, and the transmission performance parameters and reception performance parameters of the target antenna 302 under different target scenarios can be determined through different configuration tables.

[0044] For example, such as Figure 2 As shown, Figure 2 The table shown is the first configuration table of this application when the target scenario includes an object with restricted electromagnetic radiation. The power limit in the scenario corresponding to the first configuration table can be 15dBm, that is, regardless of the antenna operating mode of the target antenna 302, its transmission power cannot exceed 15dBm. Combined with... Figure 2 It can be determined that the target power of this application is different in different antenna operating modes. Therefore, it can be determined that the transmission power is also different in different antenna operating modes. And the transmission power does not exceed 15dBm, so as to ensure that the protection requirements for limiting electromagnetic radiation objects are met and to avoid the problem of excessive radiation.

[0045] Continue to combine Figure 2 , Figure 2 The conducted sensitivity shown can be understood as the operating parameters of the low-noise amplifier 204. The received power is the sum of the conducted sensitivity and the received gain. The received power in the receiving mode is greater than the received power in the balanced mode and the radiated mode, so as to increase the antenna's receiving performance in the receiving mode and enable the antenna to stably receive the first radiated signal.

[0046] For example, such as Figure 3 As shown, Figure 3 The table shown is the second configuration table for a target scenario that includes objects that do not restrict electromagnetic radiation. This means the target scenario does not contain objects that restrict electromagnetic radiation; for example, electronic devices are not placed near a person but on a table. In the scenario corresponding to the second configuration table, there is no power restriction, and the target power can be adjusted to its extreme value to maximize radiation performance. Figure 3 The extreme value of the target power shown is 23, which allows us to determine the transmit power in different antenna operating modes.

[0047] The parameter values ​​in the first and second configuration tables mentioned above are merely examples, and this application does not impose any specific limitations on them. The parameter values ​​in the configuration tables can change according to changes in antenna attributes. This application only uses the parameter values ​​in the tables as examples for illustration. For example, radiation gain is used to measure the ability of an antenna to transmit signals in a specific direction, and receiving gain is used to measure the ability of an antenna to receive signals in a specific direction. Radiation gain and receiving gain are not affected by whether the target scene contains objects that restrict electromagnetic radiation.

[0048] like Figure 4 As shown, Figure 4 The table shown illustrates a third configuration table in the prior art for situations where the target scenario includes objects subject to electromagnetic radiation restriction. In this third configuration table, the target power is the same for all antenna operating modes. This is determined by reducing the target power of the power amplifier 203 to the same value, and then determining the transmit power for each antenna operating mode. Specifically, the target power is reduced to 19 dBm, and then the transmit power for each antenna operating mode is determined. It can be seen that the transmit power in the receive mode is even reduced to 10 dBm, which is far below the restriction power of 15 dBm. While this meets the protection requirements for objects subject to electromagnetic radiation restriction, the excessively low transmit power will degrade the performance of the antenna radiated signal, making it difficult for the base station to demodulate the signal. This will affect the throughput of electronic devices, leading to a decrease in the throughput of electronic devices, and may even cause the electronic devices to lose network access.

[0049] Comparing the first and third configuration tables, it can be seen that, compared to the prior art, the control method of this application can adjust the target power to 21dBm and the transmit power to 15dBm in balanced mode, and can also adjust the target power to 23dBm and the transmit power to 14dBm in receive mode. Compared to the prior art, which has a transmit power of 13dBm in balanced mode and a transmit power of 10dBm in receive mode, this application can transmit a second radiation signal at a second frequency by configuring different target powers for different antenna operating modes. This allows the transmit power in different antenna operating modes to be equal to or approach the limit power of the target scenario, thereby maximizing the antenna radiation performance in each antenna operating mode and ensuring that the electronic device containing the antenna can communicate stably with the base station.

[0050] This application can determine the target operating mode of the target antenna 302 based on the target instructions generated in the target scene, so that the target antenna 302 can receive a first radiated signal and transmit a second radiated signal based on the target operating mode. Among multiple different antenna operating modes, at least two antenna operating modes transmit the second radiated signal at a second frequency with different target powers. This enables the target antenna 302 to transmit the second radiated signal based on the current scene, solving the problem in the prior art where the power amplifier 203 transmits the radiated signal with the same power, and cannot enable the target antenna 302 to transmit the second radiated signal at a second frequency with different target powers according to the scene. This improves the radiation performance of the antenna and enables it to stably transmit signals to the base station.

[0051] In some embodiments, different target scenarios correspond to different target operating modes; different target scenarios correspond to different power limits.

[0052] In this way, the target operating mode and / or power limit are determined for different scenarios, improving the adaptability of the target scenario and operating mode and / or power limit, so as to maximize the antenna's transmission power and improve the antenna's radiation performance in each target scenario.

[0053] Optionally, the target operating mode may include: balanced mode, radiation mode, and reception mode. When the target scenario includes objects that restrict electromagnetic radiation, the target power differs in different antenna operating modes, thus determining that the transmit power also differs in each antenna operating mode.

[0054] For example, such as Figure 2 As shown, when the target scene contains objects that restrict electromagnetic radiation, when the target operating mode is determined to be balanced mode, the antenna can transmit a second radiation signal at a second frequency with a target power of 21dBm; when the target operating mode is determined to be radiation mode, the antenna can transmit a second radiation signal at a second frequency with a target power of 19dBm; and when the target operating mode is determined to be receiving mode, the antenna can transmit a second radiation signal at a second frequency with a target power of 23dBm.

[0055] Optionally, different limiting power levels can be associated with different target scenarios for limiting electromagnetic radiation. Different limiting power levels can be set for different targets to achieve the purpose of protecting them.

[0056] For example, when the object of electromagnetic radiation restriction in the target scenario is the human head, the restriction power corresponding to the target scenario can be determined to be a first restriction power, such as 15 dBm; when the object of electromagnetic radiation restriction in the target scenario is the human hand, the restriction power corresponding to the target scenario can be determined to be a second restriction power, which is different from the first restriction power.

[0057] Optionally, such as Figure 6 As shown, the electronic device may include a sensor 102 communicatively connected to the processor 101. The sensor 102 can sense the environment in which the electronic device is located to determine a power limit. For example, the electronic device can use the sensor 102 to determine that it is close to a human head, thereby determining that the power limit is a first power limit, and the processor 101 can determine the antenna operating mode based on a first configuration table.

[0058] Optionally, different configuration tables can be set for different power limits, such as... Figure 2 The first configuration table shown is for the human head, with a power limit of 15dBm. Other configuration tables can be configured for different power limits to adjust the target power, ensuring that the transmit power in different antenna operating modes is equal to or approaches the power limit of the target scenario.

[0059] In some embodiments, such as Figure 5 As shown, the control method further includes steps S201 and S202.

[0060] Step S201: The target antenna 302 is in the first antenna working mode of the target working mode, and the target parameters are obtained.

[0061] Step S202: Based on the target parameters satisfying the switching conditions, switch from the first antenna operating mode to the second antenna operating mode. In the first antenna operating mode, a second radiated signal at a second frequency is transmitted at a first target power; in the second antenna operating mode, a second radiated signal at a second frequency is transmitted at a second target power, where the first target power and the second target power are different.

[0062] In this way, when the target parameters meet the switching conditions, the antenna operating mode of the target antenna 302 can be precisely switched so that the antenna operating mode of the target antenna 302 can match the current scene. That is, the antenna can transmit radiation signals with a target power that matches the current scene, thereby achieving the goal of maximizing the radiation performance of the antenna in different scenes.

[0063] Taking the first antenna operating in balanced mode and the second antenna in receiving mode as an example, the following explanation is provided. When the target parameters meet the switching conditions, the target antenna 302 can be switched from balanced mode to receiving mode, allowing the target power to be adjusted from 21dBm to 23dBm. By increasing the target power in receiving mode, the transmit power in receiving mode can be increased. Specifically, compared to the transmit power of 10dBm in the receiving mode of existing technology, the transmit power can be increased to 14dBm, thereby improving the antenna's radiation performance in receiving mode.

[0064] Optionally, the target parameters can be related to the real-time scene in which the target antenna 302 is located. The target parameters can change in real time as the scene changes. Thus, when the scene changes, the antenna operating mode of the target antenna 302 can be adjusted in real time by judging the changes in the target parameters, so that the target antenna 302 can operate in a mode that matches the current real-time scene.

[0065] Optionally, such as Figure 6 As shown, the above-mentioned electronic device may also include a communication module 201 that is communicatively connected to the processor 101. The target parameters may be obtained by the communication module 201 and sent to the processor 101 via the communication module 201, or they may be obtained directly by the processor 101. This application does not specifically limit the method of obtaining the target parameters. As long as the processor 101 can obtain the target parameters to switch the antenna operating mode.

[0066] In some embodiments, the target parameter is a parameter generated in response to a request message received from a base station and sent to the base station, representing the performance of the target antenna 302 and its radio frequency path.

[0067] In this way, the communication status between the base station and the target antenna 302 can be characterized by the target parameters, so as to determine whether the antenna operating mode of the target antenna 302 needs to be switched based on the communication status between the base station and the target antenna 302, thereby achieving the purpose of accurately adjusting the antenna operating mode.

[0068] Optionally, the aforementioned target parameters can characterize the receiving performance and / or transmitting performance of the target antenna 302. Receiving performance may include cases where the target antenna 302 has good receiving performance, and cases where the receiving performance deteriorates. Transmitting performance may include cases where the radiated signal emitted by the target antenna 302 meets the base station requirements and is received by the base station, and cases where the radiated signal emitted by the target antenna 302 does not meet the base station requirements and cannot be received by the base station.

[0069] Optionally, the target parameters may include at least one or more of the following parameters: antenna signal-to-noise ratio and antenna transmit power margin.

[0070] In some embodiments, step S202, which involves switching from the first antenna operating mode to the second antenna operating mode based on the target parameters meeting the switching conditions, includes at least one of the following:

[0071] If the first parameter is less than the first threshold, the system switches from the first antenna operating mode to the second antenna operating mode. The first parameter being less than the first threshold indicates that the receiving performance of the target antenna 302 has deteriorated.

[0072] If the second parameter is less than the second threshold, the system switches from the first antenna operating mode to the second antenna operating mode. The second parameter being less than the second threshold indicates that the transmission performance of the target antenna 302 does not meet the requirements of the base station.

[0073] If the first parameter is less than the first threshold and the second parameter is less than the second threshold, switch from the first antenna operating mode to the second antenna operating mode.

[0074] Thus, the antenna operating mode of the target antenna 302 can be determined by the first and second parameters included in the target parameters, so that the target antenna 302 can be adjusted to an antenna operating mode that is compatible with the current scene.

[0075] Optionally, the first parameter may include at least the antenna signal-to-noise ratio (SNR). When the antenna SNR is lower than a first threshold, it indicates that the ratio of the strength of the useful signal received by the antenna to the strength of the interference signal received is low. In this case, the target antenna 302 may not be able to effectively receive the first radiated signal at the first frequency. Therefore, the target antenna 302 can be switched from the first operating mode to a second operating mode that can improve the antenna's receiving performance, such as switching the balanced mode to the receiving mode, or switching the radiating mode to the receiving mode.

[0076] This application does not specifically limit the first antenna operating mode when the first parameter is less than the first threshold. It can be a balanced mode or a radiation mode, as long as the second antenna operating mode is a mode that can improve the antenna receiving performance, i.e., a receiving mode.

[0077] Optionally, the second parameter may include at least the antenna transmit power margin. When the antenna transmit power margin is lower than the second threshold, it indicates that the transmit performance of the target antenna 302 does not meet the requirements of the base station. In this case, the target antenna 302 may not be able to effectively transmit the second radiated signal at the second frequency. Therefore, the target antenna 302 can be switched from the first operating mode to a second operating mode that can improve the antenna radiation performance, such as switching from the balanced mode to the radiation mode, or switching from the receiving mode to the radiation mode. For the case of switching from the receiving mode to the radiation mode, it is necessary to determine whether the first parameter is less than the first threshold. If so, it is necessary to remain in the receiving mode and cannot switch to the radiation mode; if not, the receiving mode can be switched to the radiation mode.

[0078] This application does not specifically limit the first antenna operating mode when the first parameter is greater than or equal to the first threshold and the second parameter is less than the second threshold. It can be a balanced mode or a receiving mode, as long as the second antenna operating mode is a mode that can improve the antenna radiation performance, i.e., a radiation mode.

[0079] Optionally, if the first parameter is less than the first threshold and the second parameter is less than the second threshold, it indicates that the ratio of the strength of the useful signal received by the antenna to the strength of the received interference signal is low, and the transmission performance of the target antenna 302 does not meet the requirements of the base station. In this case, the antenna operating mode of the target antenna 302 can be switched from the first antenna operating mode to the second antenna operating mode, which improves the receiving performance of the target antenna 302, i.e., switched to the receiving mode. The control method of this application can increase the transmission power in the receiving mode compared to the prior art, so that even if the target antenna 302 switches to the receiving mode, it can still transmit the second radiated signal of the second frequency with higher transmission power, avoiding the problem of further reducing the antenna's radiation performance when switching to the receiving mode, effectively improving the antenna's radiation performance, and enabling it to stably transmit signals to the base station.

[0080] This application also provides an electronic device. The electronic device can refer to various electronic devices such as smartphones, tablets, and laptops. This application does not limit the specific type of electronic device, as long as it has a target antenna 302. Figure 6As shown, the electronic device includes a processor 101 and an antenna adjustable module 301 for controlling the antenna, with the processor 101 and the antenna adjustable module 301 communicatively connected. The processor 101 is configured to determine a target operating mode in response to a target command in a target scene. The antenna adjustable module 301 is configured to control the target antenna 302 in the target operating mode to receive a first radiated signal at a first frequency and simultaneously transmit a second radiated signal at a second frequency; the first frequency and the second frequency belong to the same frequency band; wherein, the target operating mode includes multiple different antenna operating modes, and at least two antenna operating modes transmit the second radiated signal at the second frequency with different target powers, the target power being used to characterize the power of the radio frequency path from the antenna port of the target antenna 302 to the transceiver 202, such that the transmit power in different antenna operating modes is equal to or approaches the limiting power of the target scene.

[0081] Optionally, the aforementioned target scenario can be understood as the scenario in which the target antenna 302 is located, and the target scenario may be related to the radiation performance and reception performance of the target antenna 302.

[0082] Optionally, the aforementioned target power can be understood as the conducted target power of the antenna. The transmitted power of the antenna is the sum of the conducted target power and the radiation gain. By changing the conducted target power, the transmitted power of the antenna can be adjusted, thereby achieving the purpose of adjusting the radiation performance of the antenna.

[0083] Optionally, the aforementioned adjustable antenna module 301 is used to control and adjust the target antenna 302, which can realize the automatic positioning and rotation of the target antenna 302 in order to better receive signals.

[0084] Optionally, such as Figure 6 As shown, the aforementioned electronic device may further include a radio frequency (RF) front-end module, which is communicatively connected to the antenna adjustable module 301. The RF front-end module includes a power amplifier 203, the target power of which is the operating power of the power amplifier 203. This power amplifier can increase the signal gain to a high power level without reducing signal quality. In this application, the target power of the power amplifier 203 is different in different antenna operating modes. This ensures that the maximum transmit power that the power amplifier 203 can operate in the target scenario under different antenna operating modes is equal to or approaches the power limit of the target scenario, thereby maximizing the antenna's transmit power and effectively improving the antenna's radiation performance.

[0085] Optionally, the target scenario may include at least objects subject to electromagnetic radiation restriction and objects subject to electromagnetic radiation restriction. For example, if the target scenario in which the electronic device is located includes objects such as the human body that cannot absorb excessive electromagnetic radiation energy, then the target scenario can be determined to include objects subject to electromagnetic radiation restriction.

[0086] When the target scenario includes objects subject to electromagnetic radiation restriction, the corresponding restriction power can be determined. The restriction power can be understood as the Specific Absorption Ratio (SAR), a parameter that measures the electromagnetic radiation energy absorbed by the human body. When an electronic device approaches a human body, the transmission power of the second radiation signal emitted by the electronic device cannot exceed the SAR, i.e., it cannot exceed the restriction power, in order to protect the human body.

[0087] Optionally, the transmit power being equal to or approaching the limit power of the target scenario under different antenna operating modes can be understood as the transmit power of the antenna being less than or equal to the limit power of the target scenario, thus avoiding the problem of excessive radiation.

[0088] Optionally, a configuration table can be set for the antenna operating mode under different target scenarios. The configuration table can be stored in the processor 101 of the electronic device, and the processor 101 can call the configuration table when determining the antenna operating mode. There can be multiple configuration tables, and the transmission performance parameters and reception performance parameters of the target antenna 302 under different target scenarios can be determined through different configuration tables.

[0089] For example, such as Figure 2 As shown, Figure 2 The table shown is the first configuration table of this application when the target scenario includes an object with restricted electromagnetic radiation. The power limit in the scenario corresponding to the first configuration table can be 15dBm, that is, regardless of the antenna operating mode of the target antenna 302, its transmission power cannot exceed 15dBm. Combined with... Figure 2 It can be determined that the target power of this application is different in different antenna operating modes. Therefore, it can be determined that the transmission power is also different in different antenna operating modes. And the transmission power does not exceed 15dBm, so as to ensure that the protection requirements for limiting electromagnetic radiation objects are met and to avoid the problem of excessive radiation.

[0090] Continue to combine Figure 2 The RF front-end module may also include a low-noise amplifier 204. Figure 2 The conducted sensitivity shown can be understood as the operating parameters of the low-noise amplifier 204. The received power is the sum of the conducted sensitivity and the received gain. The received power in the receive mode is greater than that in the balanced mode and the radiated mode, so as to increase the antenna's receiving performance in the receive mode and enable the antenna to stably receive the first radiated signal.

[0091] For example, such as Figure 3 As shown, Figure 3The table shown is the second configuration table for a target scenario that includes objects that do not restrict electromagnetic radiation. This means the target scenario does not contain objects that restrict electromagnetic radiation; for example, electronic devices are not placed near a person but on a table. In the scenario corresponding to the second configuration table, there is no power restriction, and the target power can be adjusted to its extreme value to maximize radiation performance. Figure 3 The extreme value of the target power shown is 23, which allows us to determine the transmit power in different antenna operating modes.

[0092] The parameter values ​​in the first and second configuration tables mentioned above are merely examples, and this application does not impose any specific limitations on them. The parameter values ​​in the configuration tables can change according to changes in antenna attributes. This application only uses the parameter values ​​in the tables as examples for illustration. For example, radiation gain is used to measure the ability of an antenna to transmit signals in a specific direction, and receiving gain is used to measure the ability of an antenna to receive signals in a specific direction. Radiation gain and receiving gain are not affected by whether the target scene contains objects that restrict electromagnetic radiation.

[0093] like Figure 4 As shown, Figure 4 The table shown illustrates a third configuration table in the prior art for situations where the target scenario includes objects subject to electromagnetic radiation restriction. In this third configuration table, the target power is the same for all antenna operating modes. This is determined by reducing the target power of the power amplifier 203 to the same value, and then determining the transmit power for each antenna operating mode. Specifically, the target power is reduced to 19 dBm, and then the transmit power for each antenna operating mode is determined. It can be seen that the transmit power in the receive mode is even reduced to 10 dBm, which is far below the restriction power of 15 dBm. While this meets the protection requirements for objects subject to electromagnetic radiation restriction, the excessively low transmit power will degrade the performance of the antenna radiated signal, making it difficult for the base station to demodulate the signal. This will affect the throughput of electronic devices, leading to a decrease in the throughput of electronic devices, and may even cause the electronic devices to lose network access.

[0094] Comparing the first and third configuration tables, it can be seen that, compared to the prior art, the control method of this application can adjust the target power to 21dBm and the transmit power to 15dBm in balanced mode, and can also adjust the target power to 23dBm and the transmit power to 14dBm in receive mode. Compared to the prior art, which has a transmit power of 13dBm in balanced mode and a transmit power of 10dBm in receive mode, this application can transmit a second radiation signal at a second frequency by configuring different target powers for different antenna operating modes. This allows the transmit power in different antenna operating modes to be equal to or approach the limit power of the target scenario, thereby maximizing the antenna radiation performance in each antenna operating mode and ensuring that the electronic device containing the antenna can communicate stably with the base station.

[0095] This application can determine the target operating mode of the target antenna 302 based on the target instructions generated in the target scene, so that the target antenna 302 can receive a first radiated signal and transmit a second radiated signal based on the target operating mode. Among multiple different antenna operating modes, at least two antenna operating modes transmit the second radiated signal at a second frequency with different target powers. This enables the target antenna 302 to transmit the second radiated signal based on the current scene, solving the problem in the prior art where the power amplifier 203 transmits the radiated signal with the same power, and cannot enable the target antenna 302 to transmit the second radiated signal at a second frequency with different target powers according to the scene. This improves the radiation performance of the antenna and enables it to stably transmit signals to the base station.

[0096] In some embodiments, such as Figure 6 As shown, the electronic device further includes a communication module 201 and a power amplifier 203. The processor 101 is also configured to send a first control command to the communication module 201 based on a target power corresponding to the determined target operating mode. The communication module 201 is also configured to control the power amplifier 203 to operate at the corresponding target power based on the first control command.

[0097] Optionally, the communication module 201 is an electronic device that can modulate digital signals onto analog signals for transmission and demodulate received analog signals into digital signals. Its function is to generate analog signals that can be easily transmitted and to decode and restore the original digital signals to communicate with the base station in accordance with the communication protocol.

[0098] Optionally, such as Figure 6 As shown, the radio frequency front-end module of the above-mentioned electronic device may further include a transceiver 202 and a multiplexer 205 that are communicatively connected to the communication module 201. The transceiver 202 includes a receiver and a transmitter for transmitting electromagnetic signals. The multiplexer 205 is used to isolate the transmitted signal from the received signal.

[0099] Optionally, the first control command sent by the communication module 201 can be received by the transceiver 202 to control the operating power of the power amplifier 203 via the transceiver 202.

[0100] When the target antenna is determined to be in the first antenna operating mode, the processor 101 will send a first control command to the communication module 201 after determining the target operating mode. This enables the communication module 201 to send a second control command to the transceiver 202 based on the first control command. The transceiver 202 controls the power amplifier 203 based on the second control command, so that the power amplifier 203 operates at the corresponding target power. The power amplifier 203 is used to control the transmission power of each radiated signal. After the communication module 201 controls the operating power of the power amplifier 203, the corresponding signal will be sent to the antenna adjustable module 301 via the multiplexer 205. This enables the antenna adjustable module 301 to control the target antenna 302 to radiate signals outward at the aforementioned transmission power.

[0101] Furthermore, when it is determined that the target antenna is in the first antenna operating mode, the processor 101 will also send a third control command to the antenna adjustable module 301, so that the antenna adjustable module 301 can receive the first radiation signal at the first frequency and send the second radiation signal at the second frequency.

[0102] For example, such as Figure 2 As shown, when the target antenna is determined to be in balanced mode, the processor 101 determines the target power value to be 21 and generates a first control command based on this to control the power amplifier 203 to operate at the target power of 21 via the communication module 201 and transceiver 202. Furthermore, the processor 101 also determines the radiation gain value of the target antenna to be -6 and the reception gain value to be -8, and generates a third control command based on this to control the operation of the antenna adjustable module 301, enabling the antenna adjustable module 301 to control the target antenna 302 to operate at a radiation gain value of -6 and a reception gain value of -8.

[0103] Optionally, the communication module 201 can adjust the target power of the power amplifier 203 by increasing the power supply, that is, by increasing the power supplied to the power amplifier 203 to increase the target power, and by decreasing the power supplied to the power amplifier 203 to decrease the target power.

[0104] In some embodiments, the processor 101 is further configured to correspond to different target operating modes for different target scenarios; and different target scenarios correspond to different power limits.

[0105] In this way, the target operating mode and / or power limit are determined for different scenarios, improving the adaptability of the target scenario and operating mode and / or power limit, so as to maximize the antenna's transmission power and improve the antenna's radiation performance in each target scenario.

[0106] Optionally, the target operating mode may include: balanced mode, radiation mode, and receiving mode. When the target scenario includes objects that restrict electromagnetic radiation, the target power differs in different operating modes, thus determining that the transmission power also differs in each operating mode.

[0107] For example, such as Figure 2 As shown, when the target scene contains objects that restrict electromagnetic radiation, when the target operating mode is determined to be balanced mode, the antenna can transmit a second radiation signal at a second frequency with a target power of 21dBm; when the target operating mode is determined to be radiation mode, the antenna can transmit a second radiation signal at a second frequency with a target power of 19dBm; and when the target operating mode is determined to be receiving mode, the antenna can transmit a second radiation signal at a second frequency with a target power of 23dBm.

[0108] Optionally, different limiting power levels can be associated with different target scenarios for limiting electromagnetic radiation. Different limiting power levels can be set for different targets to achieve the purpose of protecting them.

[0109] For example, when the object of electromagnetic radiation restriction in the target scenario is the human head, the restriction power corresponding to the target scenario can be determined to be a first restriction power, such as 15 dBm; when the object of electromagnetic radiation restriction in the target scenario is the human hand, the restriction power corresponding to the target scenario can be determined to be a second restriction power, which is different from the first restriction power.

[0110] Optionally, such as Figure 6 As shown, the electronic device may include a sensor 102 communicatively connected to the processor 101. The sensor 102 can sense the environment in which the electronic device is located to determine a power limit. For example, the electronic device can use the sensor 102 to determine that it is close to a human head, thereby determining that the power limit is a first power limit, and the processor 101 can determine the antenna operating mode based on a first configuration table.

[0111] Optionally, different configuration tables can be set for different power limits, such as... Figure 2 The first configuration table shown is for the human head, with a power limit of 15dBm. Other configuration tables can be configured for different power limits to adjust the target power, ensuring that the transmit power in different antenna operating modes is equal to or approaches the power limit of the target scenario.

[0112] In some embodiments, the electronic device further includes a communication module 201, wherein the processor 101 or the communication module 201 is configured to obtain target parameters by having the target antenna 302 operate in a first antenna mode under the target operating mode. The processor 101 is further configured to switch from the first antenna mode to a second antenna mode based on the target parameters satisfying a switching condition; wherein, in the first antenna mode, a second radiated signal at a second frequency is transmitted at a first target power; and in the second antenna mode, a second radiated signal at a second frequency is transmitted at a second target power, wherein the first target power is different from the second target power.

[0113] In this way, when the target parameters meet the switching conditions, the antenna operating mode of the target antenna 302 can be precisely switched so that the operating mode of the target antenna 302 can match the current scene. That is, the antenna can transmit radiation signals with a target power that matches the current scene, thereby achieving the goal of maximizing the radiation performance of the antenna in different scenes.

[0114] Taking the first antenna operating in balanced mode and the second antenna in receiving mode as an example, the following explanation is provided. When the target parameters meet the switching conditions, the target antenna 302 can be switched from balanced mode to receiving mode, allowing the target power to be adjusted from 21dBm to 23dBm. By increasing the target power in receiving mode, the transmit power in receiving mode can be increased. Specifically, compared to the transmit power of 10dBm in the receiving mode of existing technology, the transmit power can be increased to 14dBm, thereby improving the antenna's radiation performance in receiving mode.

[0115] Optionally, the target parameters can be related to the real-time scene in which the target antenna 302 is located. The target parameters can change in real time as the scene changes. Thus, when the scene changes, the antenna operating mode of the target antenna 302 can be adjusted in real time by judging the changes in the target parameters, so that the target antenna 302 can operate in a mode that matches the current real-time scene.

[0116] Optionally, such as Figure 6 As shown, the target parameters can be obtained by the communication module 201 and sent to the processor 101 via the communication module 201, or they can be obtained directly by the processor 101. This application does not specify the method of obtaining the target parameters. As long as the processor 101 can obtain the target parameters to switch the antenna operating mode, it is fine.

[0117] In some embodiments, the target parameter is a parameter generated in response to a request message received from a base station and sent to the base station, representing the performance of the target antenna 302 and its radio frequency path.

[0118] In this way, the communication status between the base station and the target antenna 302 can be characterized by the target parameters, so as to determine whether the antenna operating mode of the target antenna 302 needs to be switched based on the communication status between the base station and the target antenna 302, thereby achieving the purpose of accurately adjusting the antenna operating mode.

[0119] Optionally, the aforementioned target parameters can characterize the receiving performance and / or transmitting performance of the target antenna 302. Receiving performance may include cases where the target antenna 302 has good receiving performance, and cases where the receiving performance deteriorates. Transmitting performance may include cases where the radiated signal emitted by the target antenna 302 meets the base station requirements and is received by the base station, and cases where the radiated signal emitted by the target antenna 302 does not meet the base station requirements and cannot be received by the base station.

[0120] Optionally, the target parameters may include at least one or more of the following parameters: antenna signal-to-noise ratio and antenna transmit power margin.

[0121] In some embodiments, the processor 101 is further configured to perform at least one of the following steps:

[0122] Step 1: If the first parameter is less than the first threshold, switch from the first antenna working mode to the second antenna working mode. The first parameter being less than the first threshold indicates that the receiving performance of the target antenna 302 has deteriorated.

[0123] Step 2: If the second parameter is less than the second threshold, switch from the first antenna working mode to the second antenna working mode. The second parameter being less than the second threshold indicates that the transmission performance of the target antenna 302 does not meet the requirements of the base station.

[0124] Step 3: If the first parameter is less than the first threshold and the second parameter is less than the second threshold, switch from the first antenna working mode to the second antenna working mode.

[0125] Thus, the antenna operating mode of the target antenna 302 can be determined by the first and second parameters included in the target parameters, so that the target antenna 302 can be adjusted to an antenna operating mode that is compatible with the current scene.

[0126] Optionally, the first parameter may include at least the antenna signal-to-noise ratio (SNR). When the antenna SNR is lower than a first threshold, it indicates that the ratio of the strength of the useful signal received by the antenna to the strength of the interference signal received is low. In this case, the target antenna 302 may not be able to effectively receive the first radiated signal at the first frequency. Therefore, the target antenna 302 can be switched from the first operating mode to a second operating mode that can improve the antenna's receiving performance, such as switching the balanced mode to the receiving mode, or switching the radiating mode to the receiving mode.

[0127] This application does not specifically limit the first antenna operating mode when the first parameter is less than the first threshold. It can be a balanced mode or a radiation mode, as long as the second antenna operating mode is a mode that can improve the antenna receiving performance, i.e., a receiving mode.

[0128] Optionally, the second parameter may include at least the antenna transmit power margin. When the antenna transmit power margin is lower than the second threshold, it indicates that the transmit performance of the target antenna 302 does not meet the requirements of the base station. In this case, the target antenna 302 may not be able to effectively transmit the second radiated signal at the second frequency. Therefore, the target antenna 302 can be switched from the first operating mode to a second operating mode that can improve the antenna radiation performance, such as switching from the balanced mode to the radiation mode, or switching from the receiving mode to the radiation mode. For the case of switching from the receiving mode to the radiation mode, it is necessary to determine whether the first parameter is less than the first threshold. If so, it is necessary to remain in the receiving mode and cannot switch to the radiation mode; if not, the receiving mode can be switched to the radiation mode.

[0129] This application does not specifically limit the first antenna operating mode when the first parameter is greater than or equal to the first threshold and the second parameter is less than the second threshold. It can be a balanced mode or a receiving mode, as long as the second antenna operating mode is a mode that can improve the antenna radiation performance, i.e., a radiation mode.

[0130] Optionally, if the first parameter is less than the first threshold and the second parameter is less than the second threshold, it indicates that the ratio of the strength of the useful signal received by the antenna to the strength of the received interference signal is low, and the transmission performance of the target antenna 302 does not meet the requirements of the base station. In this case, the operating mode of the target antenna 302 can be switched from the first antenna operating mode to the second antenna operating mode, which improves the receiving performance of the target antenna 302, i.e., switched to the receiving mode. The control method of this application can increase the transmission power in the receiving mode compared to the prior art, so that even if the target antenna 302 switches to the receiving mode, it can still transmit the second radiated signal of the second frequency with higher transmission power, avoiding the problem of further reducing the antenna's radiation performance when switching to the receiving mode, effectively improving the antenna's radiation performance, and enabling it to stably transmit signals to the base station.

[0131] The following example illustrates how the target antenna switches from balanced mode to receive mode. Figure 2As shown, when the target antenna switches from balanced mode to receive mode, the processor 101 determines that the target power value changes from 21 to 23, and generates a first control command accordingly to control the power amplifier 203 to operate at the target power of 23 via the communication module 201 and transceiver 202. Furthermore, the processor 101 also determines that the radiation gain value of the target antenna changes from -6 to -9, and the receive gain value changes from -8 to -6, and generates a third control command accordingly to control the operation of the adjustable antenna module 301, enabling the adjustable antenna module 301 to control the target antenna 302 to operate with a radiation gain value of -9 and a receive gain value of -6.
