The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute commands sent by the processor 110.

When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Then, the processor 110 provides corresponding visual output on the display panel 1061 according to the type of touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to realize the input and output functions of the smart terminal.

Optionally, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 110.

[0067] The intelligent terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby managing functions such as charging, discharging, and power consumption through the power management system.

[0068] although Figure 1 Not shown, the smart terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0069] To facilitate understanding of the embodiments of the present application, the communication network system on which the smart terminal of the present application is based is described below.

[0074] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem) or other IP services.

[0075] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., without limitation here.

[0076] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0077] In order to facilitate the understanding of the present application, the prior art involved in the present application is firstly described by way of example.

[0078] When the smart terminal is communicating, the antenna of the smart terminal needs to meet specific radiation performance indicators, such as the total radiated power (TRP) of the antenna, so as to meet the network experience of the user when making calls or surfing the Internet. However, as a source of electromagnetic wave radiation, the antenna will also have a certain radiation dose impact on the user's physical health. In order to characterize the impact of the generated radiation dose on the user's physical health, it is usually measured by the specific absorption rate (SAR), where SAR refers to the electromagnetic radiation power absorbed by the organism per unit mass. The lower the SAR value, the less radiation is absorbed by the organism, and the higher the SAR value, the more radiation is absorbed by the organism.

[0079] It should be noted that the radiation performance index and SAR are a pair of contradictory indicators. The higher the radiation performance index, the better the network communication performance of the smart terminal, but the user is more affected by electromagnetic radiation.

[0080] At present, in order to reduce the SAR value of smart terminals, the antenna transmission power is generally reduced. That is, in the frequency band with relatively high SAR, the antenna radiation power is maintained at a certain low level by reducing the RF conduction power of the antenna in the corresponding frequency band, so that the radiation to the human body, that is, SAR, meets the requirements.

[0081] For example, a sensor is usually set on the main board of the smart terminal, see Figure 3 , Figure 3 An exemplary structural diagram provided for this application is shown in Figure 3 The smart terminal shown is equipped with a sensor, wherein the sensor may be a proximity sensor, which senses the position of the corresponding antenna to reduce the power value of the corresponding antenna, so as to meet the design requirements of the SAR safety regulations.

[0082] However, in the above method, no matter what folding state the smart terminal is in, the antenna power is controlled only based on one sensor, which puts a heavy load on the sensor, resulting in inaccurate antenna detection results and false triggering, which in turn affects the network communication performance of the smart terminal and reduces the user's communication experience.

[0083] In order to solve the above problems, the present application proposes an antenna control method, which can be applied to a foldable smart terminal. The present application does not limit the number of foldable screens of the smart terminal, and it can be a double or triple foldable screen, etc.

[0084] See also Figure 4A , Figure 4A A schematic flow chart of an antenna control method provided in an embodiment of the present application, the method comprising the steps of:

[0085] S401: Acquire the folding state of the smart terminal and determine the target sensor.

[0086] In this embodiment, the target sensor is determined in response to the acquired current folding state of the smart terminal. Optionally, the folding state may include a fully folded state, a fully unfolded state, and at least two hovering states.

[0087] Optionally, the hovering state is a display state between a screen fully folded state and a screen fully unfolded state, that is, a state when the folding angle is greater than 0° and less than 180°.

[0088] In the present application, the intelligent terminal includes at least two sensors, the sensors may be proximity sensors, and each sensor includes a preset detection channel corresponding to each antenna.

[0089] Optionally, after the target sensor is determined, the remaining sensors enter a dormant state.

[0090] Optionally, the present application does not limit the type, quantity, and installation location of the sensor in the smart terminal, which can be determined based on actual application conditions.

[0091] Optionally, the smart terminal is provided with two sensors as an example, including sensor 1 and sensor 2, please refer to Table 1, Table 1 presets the configuration information related to sensor 1 and sensor 2, including but not limited to: multiple detection channels of sensor 1 and antennas detectable by each detection channel, multiple detection channels of sensor 2 and antennas detectable by each detection channel, target sensors in working state in different folding states of the smart terminal, etc.

[0092] Table 1

[0093]

[0094]

[0095] Optionally, according to the configuration information in Table 1, when it is detected that the current folding state of the smart terminal is the screen fully unfolded or hovering state, the target sensor determined is sensor 1, and sensor 2 enters the dormant state. When it is detected that the current folding state of the smart terminal is the screen fully folded state, the target sensor determined is sensor 2, and sensor 1 enters the dormant state, see Figure 4B , Figure 4B A schematic diagram of a target sensor for determining an embodiment of the present application.

[0096] S402: Determine the distance between the user and the antenna through a target sensor.

[0097] Optionally, for any antenna of the smart terminal, the distance between the user and the antenna is determined by a target sensor according to a detection channel preset for the antenna.

[0098] Optionally, when a human hand or body part holds, approaches or moves away from a smart terminal, the capacitance value detected by the sensor will change. Therefore, the distance between the user and the antenna can be determined based on the detected capacitance value, thereby controlling the transmission power of the antenna.

[0099] Optionally, a mapping relationship between capacitance value and distance is preset in the present application, and the mapping relationship between capacitance value and distance is obtained, and the distance in the preset detection direction is determined according to the capacitance value corresponding to the preset detection direction and the mapping relationship. Therefore, after the capacitance value is determined, the distance between the user and the antenna can be determined according to the mapping relationship.

[0102] Optionally, assuming that the determined target sensor is sensor 1, for any antenna of the smart terminal, such as ANT3, the capacitance value of ANT3 is detected through the detection channel RXI01 corresponding to ANT3, and the distance between the user and ANT3 is determined according to the mapping relationship between the preset capacitance value and the distance, where ANT3 can be an antenna for transmitting medium and high frequency signals.

Optionally, ANT18orANT7 can be an antenna that transmits low-frequency signals.

[0104] Optionally, Figure 5 The number, position, and function of the antennas shown in the figure are only for illustration and do not limit the present application.

[0105] S403: Control the transmission power of the antenna according to the distance.

[0106] In this embodiment, the transmit power of the antenna may be controlled according to the distance so that the SAR value of the antenna meets a preset SAR threshold.

[0107] Optionally, if the distance is less than or equal to the distance threshold, the transmit power of the antenna is reduced until it is detected that the distance is greater than the distance threshold, so that the SAR value of the antenna meets a preset SAR threshold.

[0108] Optionally, if the distance is greater than the distance threshold, the current transmit power of the antenna is maintained.

[0109] In the above embodiment of the present application, the target sensor is determined by acquiring the folding state of the smart terminal, the distance between the user and the antenna is determined by the target sensor, and the transmission power of the antenna is controlled according to the distance. This embodiment sets at least two sensors, and can determine the target sensor for detection according to the folding state of the smart terminal, thereby reducing the loss of the smart terminal when multiple folding states use one sensor, and the detection is more accurate, the control of the antenna is more accurate, and the user's network experience is improved.

[0110] Optionally, based on the above embodiment, the following embodiment illustrates a process of determining the distance between the user and the antenna through a target sensor.

[0111] See also Figure 6 , Figure 6 A flow chart of a method for determining distance provided in an embodiment of the present application, the method comprising the following steps:

[0112] S601. Detect the capacitance value of the antenna through a preset detection channel corresponding to the antenna in the target sensor.

[0113] In this embodiment, antennas detectable by various detection channels of the target sensor are preset, and the capacitance value of the corresponding antenna can be detected through the corresponding detection channel.

[0114] S602: Determine the distance according to the capacitance value.

[0115] Optionally, for at least one detection channel, a detection direction to be detected is preset on the detection channel, wherein the detection direction may be a positional relationship between the antenna and different surfaces of the smart terminal. For example, assuming that the side of the smart terminal facing the user is the front, the detection direction may include the front, back, top, bottom, left side and right side.

[0116] Optionally, the target sensor obtains a preset detection direction corresponding to the detection channel, detects the capacitance value in each detection direction, and obtains the distance in each detection direction according to a mapping relationship between the preset capacitance value and the distance.

[0117] Optionally, the preset detection directions corresponding to the preset detection channels of the antenna are shown in Table 2.

[0118] Table 2 (this table expands Table 3)

[0119]

[0120] Table 3

[0121]

[0122] Optionally, the specific preset detection direction corresponding to each detection channel is related to the position of the antenna in the smart terminal. In the above Table 2, only the preset detection directions corresponding to some of the detection channels are shown, and the remaining detection channels are not illustrated to avoid redundancy. The content shown in Table 2 does not limit the present application.

[0123] Optionally, assuming that the detection channel RXI03 can correspond to CHO in Table 2, RXI01 can correspond to CH1 in Table 2, and the detection channel RXI00 can correspond to CH4 in Table 2, it can be understood that the above correspondence is only for illustration and can be flexibly configured according to actual application conditions, etc., and this application does not limit it.

[0124] Optionally, taking ANT3 as an example, according to Table 1, it can be determined that the detection channel for detecting ANT3 in the target sensor is RXI01. In Table 2, CH1 corresponds to RXI01. According to the configuration of CH1, it can be determined that the preset detection direction corresponding to the detection channel RXI01 is in front of, behind, and on the right side of the smart terminal. The capacitance values ​​corresponding to the above-mentioned detection directions are detected, and the distance between the user and the antenna in front of, behind, and on the right side of the smart terminal is determined based on the capacitance values ​​in each detection direction and the mapping relationship between the preset capacitance values ​​and the distance.

[0125] Optionally, taking ANT13 as an example, according to Table 1, it can be determined that the detection channel for detecting ANT13 in the target sensor is RXI03. In Table 2, CH0 corresponds to RXI03. According to the configuration of CH0, it can be determined that the preset detection direction corresponding to the detection channel RXI01 is in front of, behind, above, and on the left side of the smart terminal. The capacitance values ​​corresponding to the above-mentioned detection directions are detected, and the distance between the user and the antenna in front of, behind, on the top, and on the left side of the smart terminal is determined based on the capacitance values ​​in each detection direction and the mapping relationship between the preset capacitance values ​​and the distance.

[0126] In the above-mentioned embodiment of the present application, the capacitance value of the antenna is detected by a preset detection channel of the target sensor corresponding to the antenna, and the distance between the user and the antenna determined according to the capacitance value is more accurate.

[0127] Optionally, based on the above embodiment, the process of controlling the transmission power of the antenna according to the distance is described through the following embodiment.

[0128] See also Figure 7 , Figure 7 A flow chart of a control method provided in an embodiment of the present application, the method comprises the following steps:

[0129] S701: Determine a distance threshold based on a target scene mode.

[0130] Optionally, before determining the distance threshold, the target scene mode needs to be determined first.

[0131] Optionally, a possible implementation manner of determining the target scene mode may be: acquiring status information of a preset function module of the smart terminal, and determining the target scene mode according to the distance and the status information.

[0132] Optionally, the preset functional modules include but are not limited to: headphones, receivers, Bluetooth, and WIFI.

[0133] Optionally, the state information includes but is not limited to: an open state, a closed state, and an empty set state.

[0134] In this embodiment, a scene mode table is preset, in which the distance range corresponding to each scene mode and the status information of the preset function module are preset.

[0135] Therefore, according to the currently determined distance and the current state information of the preset function module of the smart terminal, the target scene mode can be determined from the scene mode table.

[0136] Optionally, multiple scene modes are preset in this application.

[0137] As shown in Table 3:

[0138] Table 3

[0139]

[0140]

[0141] In Table 3, "0" represents the off state and "1" represents the on state, or "1" represents the off state and "0" represents the on state. This application does not limit the states represented by "0" and "1", and "NA" represents an empty set.

[0142] Optionally, after the target scene mode is determined, a distance threshold is determined.

[0143] Optionally, the scene mode table also presets a judgment condition corresponding to each scene mode, and the distance threshold can be determined from the judgment condition.

[0144] Optionally, taking ANT3 as an example, the antenna corresponds to CH1 in Table 2 with RXI01. According to the configuration of CH1, the preset detection direction corresponding to the detection channel RXI01 is determined to be the front, back and right side of the smart terminal. The distance between the user and the antenna in front of the smart terminal is 2mm, the distance in the back is 13mm and 8mm, and the distance in the right side is 16mm and 10mm. The reason why there are two values ​​in some directions is that in order to improve the accuracy of the detection, two detections are triggered, but not all directions need to be detected twice, and only one detection can be performed according to the preset configuration. According to the above distances between the user and the antenna in different directions, it is determined that the weakest sensing surface of ANT3 detected by the detection channel is the back, with a distance of 8mm.

[0145] Assume that the working status data of the preset functional modules are: the headset is "0", the smart terminal is in the expanded state "1", the Bluetooth or WIFI is "0", and the receiver is "0".

[0146] According to the distance of 8mm and the status information of the preset functional module, it can be determined from Table 3 that the target scene mode is DSI-3. According to the "judgment conditions" in Table 3, the distance threshold under the target scene mode DSI-3, namely "distance ≦ 16mm", can be determined.

[0147] S702: Control the transmit power of the antenna according to the relationship between the distance and the distance threshold.

[0148] For any antenna, when the distance between the detected user and the antenna is less than or equal to the distance threshold, it means that the distance between the user and the antenna is too close and exceeds the safety distance, which may affect the user. Therefore, it is necessary to control the antenna to perform power backoff until the distance is greater than the distance threshold so that the SAR value of the antenna meets the requirement.

[0149] When the detected distance between the user and the antenna is greater than the distance threshold, it means that the distance between the user and the antenna is far but within the safety distance unit. Therefore, there is no need to control the antenna to perform power backoff, and the antenna transmission power can be maintained.

[0150] In the present application, different scene modes are also pre-configured for different antennas. As shown in Table 4, when the antenna corresponds to a signal for transmitting the Long Term Evolution (LTE) B3 frequency band, i.e., LTE B3, it corresponds to a preset multiple scene modes (DSI-0 to DSI-13). When the antenna corresponds to a signal for transmitting the N3 frequency band, it corresponds to a preset multiple scene modes (DSI-0 to DSI-13).

[0152]

[0153] Optionally, GSM stands for Global System for Mobile Communications, WCDMA stands for Wideband Code Division Multiple Access, and B3, B1, N3, and N78 are used to represent frequency bands in different frequency ranges.

[0154] In Table 4, A1 to AN represent different scene modes corresponding to the LTE B3 frequency band, B1 to BN represent different scene modes corresponding to the GSM 1800 frequency band, C1 to CN represent different scene modes corresponding to the WCDMA B1 frequency band, D1 to DN represent different scene modes corresponding to the N3 frequency band, and E1 to EN represent different scene modes corresponding to the N78 frequency band. The specific contents corresponding to each scene mode are similar to those in Table 3, and will not be repeated to avoid redundancy.

[0155] Optionally, in the above embodiment of the present application, the intelligent terminal determines the distance threshold based on the target scene mode, and controls the transmission power of the antenna according to the distance and the distance threshold. The method of this embodiment controls the transmission power of the antenna according to the relationship between the detected distance and the distance threshold, so that the control of the antenna is more accurate, further improving the user experience.
