DETAILED DESCRIPTION
[0045] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, not all of the embodiments. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present application.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.
[0047] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0048] The present application provides a radio frequency system 100. The radio frequency system 100 is applied to an electronic device 1000.
[0049] See also Figure 1 , Figure 11 is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of the present application. The electronic device 1000 includes but is not limited to a mobile phone, a tablet computer, a laptop computer, a computer, a wearable device, a drone, a robot, a digital camera, and other devices with communication functions. The present embodiment of the application is described by taking a mobile phone as an example, and other electronic devices can refer to this embodiment.
[0050] In other words, the electronic device 1000 provided in the present application includes the aforementioned radio frequency system 100 .
[0051] See also Figure 2 and Figure 3 The RF system 100 includes a RF module 10. The RF module 10 is used to obtain characteristic parameters of the RF signal transmitted by the RF front-end circuit 20, and identify the movement state and surrounding environment state of the electronic device 1000 according to the size and change of the characteristic parameters.
[0052] Please refer to Figure 1 The form of the RF module 10 includes but is not limited to a circuit disposed on the circuit board 600, or an independently packaged chip, or a chip integrated and packaged together with other circuits.
[0053] Please refer to Figure 2 The RF module 10 includes a parameter acquisition unit 11 and a calculation unit 12. The parameter acquisition unit 11 and the calculation unit 12 may be in the form of a circuit disposed on the circuit board 600, or an independently packaged chip, or a chip integrated with other circuits.
[0054] Please refer to Figure 4 The parameter acquisition unit 11 is configured to acquire characteristic parameters of the radio frequency signal transmitted by the radio frequency front-end circuit 20.
[0055] Specifically, the RF front-end circuit 20 includes but is not limited to a RF link between the RF transceiver unit and the antenna radiator. The RF front-end circuit 20 may also be referred to as a RF front-end module (RFFE). The RF front-end circuit 20 includes but is not limited to a power amplifier (PA), an antenna switch (Switch), a filter (Filter), a duplexer (Duplexer) and a low noise amplifier (LNA), etc. The RF front-end circuit 20 includes at least one of a RF transmission channel and a RF receiving channel to ensure the effective reception and transmission of wireless signals. Among them, the power amplifier is used to enhance the RF signal of the transmission channel. The antenna switch is used to switch the RF signal between the receiving and transmitting states, and to switch between different frequency bands. The filter is used to filter out signals in a specific frequency band and filter out other unnecessary frequency band signals. The duplexer is used to ensure the isolation of the transmission and reception signals so that both can work normally when the antenna radiator is shared. The low noise amplifier is used to amplify the RF signal of the receiving channel.
[0056] The RF front-end circuit 20 may be in the form of a circuit disposed on the circuit board 600 , or an independently packaged chip, or a chip integrated and packaged together with other circuits.
[0057] The parameter acquisition unit 11 includes a first signal input terminal, which is electrically connected to the RF front-end circuit 20 to obtain characteristic parameters of the RF signal transmitted by the RF front-end circuit 20. The electrical connection between the first signal input terminal and the RF front-end circuit 20 in the present application includes but is not limited to a direct electrical connection or a capacitive coupling electrical connection.
[0058] The characteristic parameters include current, voltage, power, and other characteristic quantities that can characterize the magnitude and direction of power. The characteristic quantity can be an analog signal or a digital signal.
[0059] The characteristic parameter is used to characterize at least one of the power size and power direction of the radio frequency signal. Since the power of the radio frequency signal is a vector, the power size, power value change, and power direction change can be obtained to identify the state of the electronic device 1000.
[0060] The position where the first signal input terminal is electrically connected to the RF front-end circuit 20 is not specifically limited. For example, the first signal input terminal is coupled to the output terminal of the power amplifier to obtain the output power of the power amplifier. For further example, the parameter acquisition unit 11 is a power detection circuit.
[0061] In this implementation manner, the calculation unit 12 is electrically connected to the parameter acquisition unit 11 .
[0062] Exemplarily, the calculation unit 12 includes a second signal input terminal, and the second signal input terminal is electrically connected to the output terminal of the parameter acquisition unit 11 .
[0063] The calculation unit 12 is configured to determine the state of the electronic device 1000 according to the characteristic parameter. The state of the electronic device 1000 includes the movement state of the electronic device 1000 and / or the state of the peripheral environment where the electronic device 1000 is located.
[0064] Exemplarily, the calculation unit 12 determines the movement state of the electronic device 1000 according to the change rate and change rule of the characteristic parameter. The movement state of the electronic device 1000 includes but is not limited to the electronic device 1000 being in a high-speed movement state, and the corresponding scenes include but are not limited to subway mode, high-speed rail mode, highway mode, etc.
[0065] Exemplarily, the peripheral environment state of the electronic device 1000 includes but is not limited to a protective case state, a basement state, an elevator state, a handheld state, etc.
[0066] In general technology, the high-speed moving state of the electronic device 1000 needs to be detected by sensors, etc. The sensors feed back the detection results to the first processor (such as AP) in the electronic device 1000, and the first processor optimizes and regulates the parameters of the RF front-end circuit 20 by sending control instructions through the modem and the RF transceiver unit. On the one hand, the state identification of the electronic device 1000 needs to call the sensor and process the data through the first processor (AP). The time difference of the sensor's identification is obviously not conducive to scene optimization. The whole response process is relatively long, and the response time is too long; it will also occupy the resources of the first processor (AP).
[0067] The present application provides a radio frequency system 100, which is applied to an electronic device 1000. The radio frequency system 100 includes a radio frequency module 10, and the radio frequency module 10 includes a parameter acquisition unit 11 and a calculation unit 12. The parameter acquisition unit 11 is configured to acquire characteristic parameters of a radio frequency signal transmitted by a radio frequency front-end circuit 20, and the characteristic parameters are used to characterize at least one of the power size and the power direction of the radio frequency signal. The calculation unit 12 is electrically connected to the parameter acquisition unit 11, and the calculation unit 12 is configured to determine the state of the electronic device 1000 according to the characteristic parameters. The state of the electronic device 1000 includes the movement state of the electronic device 1000 and / or the state of the peripheral environment in which the electronic device 1000 is located. The present application determines the movement state of the electronic device 1000 and / or the state of the peripheral environment in which the electronic device 1000 is located according to the characteristic parameters of the radio frequency signal of the radio frequency front-end circuit 20 collected by the radio frequency system 100, and determines the movement state of the electronic device 1000 and / or the state of the peripheral environment in which the electronic device 1000 is located according to the size and change of the characteristic parameters, without calling sensors, which can reduce the setting of sensors and shorten the recognition response time, thereby facilitating the realization of closed-loop precise control and improving the state recognition capability of the electronic device 1000.
[0068] The following is an example of the process in which the calculation unit 12 determines the state of the electronic device 1000 according to the size and change rate of the characteristic parameter.
[0069] It should be noted that the characteristic parameters include the power of the radio frequency signal, which is a vector, and the power of the vector includes the power magnitude and the power direction. Among them, the power magnitude is the power amplitude. The power direction can be a power angle or a phase. The power magnitude and the power direction can comprehensively characterize the magnitude of the vector power of the radio frequency signal. For example, when the power magnitude remains unchanged, and the power direction of the radio frequency signal transmitted by the electronic device 1000 corresponds to the direction of the base station, the vector power of the electronic device 1000 in the working frequency band is relatively large. When the power magnitude remains unchanged, and the power direction of the radio frequency signal transmitted by the electronic device 1000 has a certain angle with the direction of the base station, the vector power of the electronic device 1000 in the working frequency band is slightly smaller. When the power magnitude remains unchanged, and the power direction of the radio frequency signal transmitted by the electronic device 1000 is opposite to the direction of the base station, the vector power of the electronic device 1000 in the working frequency band is extremely small.
[0070] Generally, when the electronic device 1000 is in a normal moving state, for example, when the moving speed of the electronic device 1000 is relatively low or stationary, the electronic device 1000 does not need to frequently switch between multiple base stations, the relative position between the electronic device 1000 and the base station remains basically unchanged or changes little, and the direction (power direction) of the radio frequency signal transmitted by the electronic device 1000 remains basically unchanged or changes very little.
[0071] When the electronic device 1000 is in a high-speed moving state, for example, in high-speed rail mode, subway mode and high-speed mode, the electronic device 1000 needs to quickly switch to interact with different base stations. The relative position between the electronic device 1000 and the same base station varies greatly. The direction (power direction) of the wireless signal transmitted by the electronic device 1000 needs to be quickly switched to ensure that the direction in which the electronic device 1000 transmits the wireless signal is relative to the direction of the base station, thereby improving the signal connection quality to ensure that the electronic device 1000 still has a high communication quality in a high-speed moving state.
[0072] The specific speed of the high-speed moving state described in this application is not specifically limited. For example, the high-speed moving state is that the electronic device 1000 is in a high-speed rail operation mode, a subway operation mode, or a highway operation mode. For example, the moving speed of the high-speed moving state is greater than or equal to 60 km / h. The normal moving state refers to a moving speed of less than 60 km / h.
[0073] In an optional implementation, the calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a high-speed moving state according to a change rate of the characteristic parameter being greater than or equal to a preset change rate.
[0074] Among them, the rate of change of the characteristic parameter includes but is not limited to the rate of change of the power direction. The electronic device 1000 can determine the preferred signal transceiving direction according to the received signal strength indication signal (RSSI, Received Signal Strength Indication). Generally, the preferred signal transceiving direction corresponds to the base station direction. However, since the electronic device 1000 is in a high-speed mobile state, the electronic device 1000 needs to quickly switch to interact with different base stations, and the relative position between the electronic device 1000 and the same base station changes greatly. Therefore, the preferred signal transceiving direction of the electronic device 1000 changes significantly faster than the preferred signal transceiving direction in the normal mobile state.
[0075] Please refer to Figure 5 For example, when the electronic device 1000 is in a high-speed moving state, taking the base station coverage radius as 1 km, the power direction of the electronic device 1000 may need to be switched once within a few seconds or tens of seconds. When the electronic device 1000 is in a normal moving state, the power direction of the electronic device 1000 may be switched once for much longer than 1 minute.
[0076] This application does not make any specific limitation on the preset change rate.
[0077] For example, the preset change rate is 1 time / 1 minute (this data is only an example).
[0078] The calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a high-speed moving state according to the change rate of the power direction being greater than or equal to 1 time / 1 minute.
[0079] The calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a normal moving state according to the change rate of the power direction being less than 1 time / 1 minute.
[0080] In other words, when the electronic device 1000 is in the high-speed rail motion mode, the interaction distance between the electronic device 1000 and the base station changes rapidly during the rapid movement of the high-speed rail. The result of its feedback to the electronic device 1000 is that the power interaction between them changes rapidly, and the power factor coupled to its front end will also change rapidly.
[0081] For another example, please refer to Figure 6, the change rule of the power direction includes but is not limited to that the change angle of the power direction within the preset time is greater than or equal to the preset angle. The preset time includes but is not limited to a few seconds or tens of seconds, and the preset angle is greater than or equal to 30°. Generally, since the high-speed rail (taking the high-speed rail mode as an example) passes through one base station after another quickly, the orientation of the base station relative to the electronic device 1000 changes greatly at different times, so the preferred signal receiving and sending direction of the electronic device 1000 changes greatly. Based on this, it can be determined that the electronic device 1000 is in a high-speed rail moving state or a normal moving state.
[0082] The calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a high-speed moving state according to the change angle of the power direction being greater than or equal to a preset angle within a preset time.
[0083] The calculation unit 12 is configured to determine that the movement state of the electronic device 1000 is a normal movement state if the change angle of the power direction within the preset time is less than a preset angle.
[0084] Please refer to Figure 6 , the angle of the power direction of the high-speed rail where the electronic device 1000 is located at position A1 varies greatly from the angle of the power direction of the high-speed rail where the electronic device 1000 is located at position A2.
[0085] In another optional implementation, please refer to Figure 7 The calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a high-speed moving state according to whether the changing rule of the characteristic parameter conforms to a preset changing rule.
[0086] The change rate of the characteristic parameter includes but is not limited to determining that the moving state of the electronic device 1000 is a high-speed moving state when the change rule of the power direction conforms to a preset change rule.
[0087] Specifically, when the electronic device 1000 is in a high-speed mobile state, the electronic device 1000 interacts with multiple base stations in sequence. Taking a high-speed railway as an example, multiple base stations are provided on one side, and the electronic device 1000 interacts with two adjacent base stations in a similar manner, so when the electronic device 1000 passes through multiple base stations, the change in power direction has a certain periodicity. For example, when the electronic device 1000 interacts with the first base station, the power direction of the electronic device 1000 (A1 position) is first 30° in the lower right corner, then switches to 90° on the right side (A2 position), and then switches to 150° in the upper right corner (A3 position); when the electronic device 1000 interacts with the second base station, the power direction of the electronic device 1000 (A4 position) switches to 30° in the lower right corner, then switches to 90° on the right side (A5 position), and then switches to 150° in the upper right corner (A6 position). When the electronic device 1000 interacts with the third base station, the power direction of the electronic device 1000 switches to 30° at the lower right corner, then switches to 90° at the right side, and then switches to 150° at the upper right corner. Similarly, of course, the above is just an example. In actual situations, due to the different distances between different base stations and high-speed railways and different weather conditions in different locations, the power direction will change, but there will be a change pattern similar to the above, similar to a periodic change. In the normal mobile state, there will be no such periodic change rule.
[0088] The present application does not specifically limit the preset change rule. For example, the change rule of the power direction includes but is not limited to the power direction of the electronic device 1000 including the upper left corner, the lower right corner, the upper left corner, the lower right corner, etc.
[0089] The calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a high-speed moving state according to whether the change rule of the power direction conforms to a preset change rule. For example, the power direction of the electronic device 1000 includes the upper left corner, the lower right corner, the upper left corner, the lower right corner, etc.
[0090] The calculation unit 12 is configured to determine that the movement state of the electronic device 1000 is a normal movement state according to the change rule of the power direction conforming to the preset change rule. The power direction of the electronic device 1000 includes upper left corner, upper left corner, upper left corner, upper left corner, etc.
[0091] The electronic device 1000 can pre-fabricate the network channel of the high-speed rail path through big data training. After the electronic device 1000 identifies the high-speed rail operation mode, the electronic device 1000 switches to the high-speed rail communication mode. The high-speed rail communication mode includes but is not limited to allowing the electronic device 1000 to adaptively track frequency deviation and automatically switch channels to achieve the effect of stable connection or fast reconnection of 4G and 5G signals.
[0092] The mode recognition of subway operation mode and highway operation mode can refer to the above-mentioned recognition of high-speed rail operation mode.
[0093] The radio frequency module 10 provided in the embodiment of the present application can also realize the identification of whether the electronic device 1000 is in a protective case state, wherein the protective case state refers to the state in which the electronic device 1000 is installed with the protective case.
[0094] Optional, see Figure 8 , the number of the RF modules 10 is multiple.
[0095] See also Figure 8 The RF system 100 further includes a processor 40 and a plurality of RF front-end circuits 20. Further, the RF system 100 further includes a plurality of antenna radiators. The processor 40 may be an application processor (AP) or a baseband processor (BP).
[0096] Optionally, each RF front-end circuit 20 includes a receiving channel and a transmitting channel. Each RF front-end circuit 20 is electrically connected to one of the antenna radiators.
[0097] Furthermore, the RF transceiver unit 60, at least one RF front-end circuit 20 and at least one antenna radiator form an antenna module. The RF system 100 includes multiple antenna modules.
[0098] See also Figure 8 , multiple antenna radiators are arranged in the frame of the electronic device 1000 or are part of the frame. The antenna radiators of multiple antenna modules are respectively arranged at different positions on the frame of the electronic device 1000, for example, the antenna radiators of multiple antenna modules are respectively arranged on the top frame 321, the first side frame 322 (for example, the left side frame), the bottom frame 323, and the second side frame 324 (for example, the right side frame) of the electronic device 1000.
[0099] Each of the RF modules 10 is electrically connected to at least one of the RF front-end circuits 20. The processor 40 is electrically connected to a plurality of the RF modules 10.
[0100] The processor 40 is configured to determine that the peripheral environment state of the electronic device 1000 is a protective shell state based on the fact that the characteristic parameters received by the computing unit 12 of each of the RF modules 10 are all less than their respective first preset power values, and the difference between the first preset power value and the power in the characteristic parameter is less than or equal to the first preset power difference.
[0101] For example, see Figure 8 and Fig. 9The plurality of RF modules 10 include a first RF module 10a, a second RF module 10b, a third RF module 10c, and a fourth RF module 10d. The processor 40 is electrically connected to the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d. The processor 40 receives the power magnitudes sent by the calculation unit 12 of the first RF module 10a, the calculation unit 12 of the second RF module 10b, the calculation unit 12 of the third RF module 10c, and the calculation unit 12 of the fourth RF module 10d.
[0102] See also Figure 8 and Fig. 9 , the first RF module 10a is electrically connected to the first antenna radiator 31 via the first RF front-end circuit 20, and the first antenna radiator 31 is located at the top frame 321 of the electronic device 1000. The second RF module 10b is electrically connected to the second antenna radiator 32 via the second RF front-end circuit 20, and the second antenna radiator 32 is located at the bottom frame 323 of the electronic device 1000. The third RF module 10c is electrically connected to the third antenna radiator 33 via the third RF front-end circuit 20, and the third antenna radiator 33 is located at the first side frame 322 of the electronic device 1000. The fourth RF module 10d is electrically connected to the fourth antenna radiator 34 via the fourth RF front-end circuit 20, and the fourth antenna radiator 34 is located at the second side frame 324 of the electronic device 1000.
[0103] If the characteristic parameters (power levels) received by the calculation units 12 of the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d are all smaller than their respective first preset power values (for example, 20dBm, but not limited to this data), and the difference between the first preset power value and the power level in the characteristic parameter is less than or equal to the first preset power difference value (for example, 4dBm, but not limited to this data).
[0104] The present application does not specifically limit the first preset power difference. Optionally, the first preset power difference may be less than the power difference between a strong signal field and a weak signal field. For example, the power value in a strong signal field is 20 dBm. The power value in a weak signal field is 10 dBm. The first preset power difference is less than 10 dBm. For example, the first preset power difference includes but is not limited to 1 dBm, 2 dBm, 3 dBm, 4 dBm, 5 dBm, 6 dBm, 7 dBm, 8 dBm, etc.
[0105] It should be noted that since the operating frequency bands and signal types of the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d may be the same or different, the first preset power values of the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d may be the same or different, and the present application does not impose any limitation on this.
[0106] In this embodiment, the first preset power value is the power of the electronic device 1000 in the working frequency band in free space. The free space refers to the state where the electronic device 1000 is not provided with a protective case and is not held. The first preset power value can be a pre-stored value, or a theoretical power value sent when the base station side calls the radio frequency system 100 on the electronic device 1000 side.
[0107] For example, the first preset power values of the first RF front-end circuit 20 , the second RF front-end circuit 20 , the third RF front-end circuit 20 , and the fourth RF front-end circuit 20 are all 20 dBm.
[0108] For example, the power magnitudes in the respective RF front-end circuits 20 obtained by the calculation units 12 of the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d are 18dBm. The difference between the first preset power value and the power magnitude in the characteristic parameter is 2dBm. The power magnitudes in the respective RF front-end circuits 20 obtained by the calculation units 12 of the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d are all less than 20dBm, and the difference is less than 4dBm. The antenna power on each side of the frame of the electronic device 1000 is smaller than the first preset power value, indicating that the electronic device 1000 is in a protective shell state.
[0109] It should be noted that the presence of the protective shell has a certain impact on the multiple antenna modules on the electronic device 1000, so the power of the antenna modules on each frame side is smaller than the power in free space, and the impact of the protective shell is smaller than the impact in weak field environments such as elevators and garages. Therefore, the overall power drop of multiple antenna modules is not very large, less than or equal to the first preset power difference, and it can be determined that the electronic device 1000 is in the protective shell state.
[0110] The processor 40 is configured to determine that the peripheral environment state of the electronic device 1000 is a protective shell state based on the fact that the power received by the computing unit 12 of each of the RF modules 10 is less than the respective first preset power values, and the difference between the first preset power value and the power size is less than or equal to the first preset power difference value.
[0111] The calculation unit 12 is configured to determine that the peripheral environment state of the electronic device 1000 is an elevator state or a basement state based on the fact that the power received by the calculation unit 12 of each of the RF modules 10 is less than the respective first preset power values, and the difference between the first preset power value and the power size is greater than the first preset power difference value.
[0112] Optionally, the processor 40 is further configured to control the power in the plurality of RF front-end circuits 20 to increase a target power value according to the peripheral environment state of the electronic device 1000 being in a protective shell state.
[0113] Specifically, when the electronic device 1000 is in a protective shell state, the processor 40 controls the power in the multiple RF front-end circuits 20 to increase the target power value. The target power value is the difference between the first preset power value and the power received by the calculation unit 12 of the RF module 10. For example, when the electronic device 1000 is in a protective shell state, the power received by the calculation unit 12 of the RF module 10 is 18dBm, which is 2dBm less than the first preset power value of 20dBm. The processor 40 controls the power in the RF front-end circuit 20 to increase by 2dBm to compensate for the power reduction caused by the protective shell.
[0114] In the present embodiment, each RF module 10 detects that the power in its respective RF front-end circuit 20 is reduced, identifies that the electronic device 1000 is in a protective case state, and feeds back the corresponding target power value compensation amount to the RF front-end circuit 20 when the electronic device 1000 is in the protective case state, so as to realize real-time and precise control of the power of the RF front-end circuit 20 without the need for sensors, and realizes fast response and closed-loop control.
[0115] In another optional implementation, please refer to Fig.10 The RF system 100 further includes a processor 40 and a functional module 50. The processor 40 is electrically connected to the RF module 10. The functional module 50 is electrically connected to the processor 40.
[0116] The processor 40 is configured to determine that the working mode of the functional module 50 is a second target working mode according to the peripheral environment state of the electronic device 1000. The second target working mode includes but is not limited to a low power consumption mode or a heat dissipation mode.
[0117] Specifically, when the processor 40 identifies that the electronic device 1000 is in a protective shell state according to the aforementioned embodiment, it can also adjust the working mode of the functional module 50 according to the protective shell state. Among them, the functional module 50 includes but is not limited to the main heat-generating chip or module in the electronic device 1000. For example, the functional module 50 includes but is not limited to the main processor 40, the battery, etc. on the main board. Since the protective shell has a slight effect on the heat dissipation of the electronic device 1000 when the electronic device 1000 is installed, the processor 40 can control these functional modules 50 to operate in a relatively low power consumption mode for chips, batteries, etc. that are easily generated in the electronic device 1000 to reduce heat generation. Further, the functional module 50 can also be a heat dissipation module. When the processor 40 identifies that the electronic device 1000 is in a protective shell state according to the aforementioned embodiment, it can also adjust the heat dissipation module to be in a heat dissipation mode or control the heat dissipation performance of the heat dissipation module to increase according to the protective shell state.
[0118] The radio frequency module 10 provided in the embodiment of the present application can also realize the identification of whether the electronic device 1000 is in a handheld state, wherein the handheld state refers to the state of the handheld electronic device 1000.
[0119] For further information, please refer to Figure 8 The RF system 100 further includes a plurality of RF front-end circuits 20 and a plurality of antenna radiators. Optionally, each RF front-end circuit 20 includes a receiving channel and a transmitting channel. Each RF front-end circuit 20 is electrically connected to one of the antenna radiators.
[0120] Furthermore, the RF transceiver unit 60, at least one RF front-end circuit 20 and at least one antenna radiator form an antenna module. The RF system 100 includes multiple antenna modules.
[0121] Multiple antenna radiators are disposed in the frame of the electronic device 1000 or are part of the frame. The antenna radiators of multiple antenna modules are respectively disposed at different positions on the frame of the electronic device 1000, for example, the antenna radiators of multiple antenna modules are respectively disposed on the top frame 321, the first side frame 322 (for example, the left side frame), the bottom frame 323, and the second side frame 324 (for example, the right side frame) of the electronic device 1000.
[0122] Optionally, there are multiple RF modules 10. Each RF module 10 is electrically connected to at least one RF front-end circuit 20. The RF system 100 further includes a processor 40. The processor 40 is electrically connected to multiple RF modules 10.
[0123] The processor 40 is configured to determine that the peripheral environment state of the electronic device 1000 is a handheld state based on the fact that the characteristic parameters received by the computing unit 12 of some of the RF modules 10 are less than or equal to their respective second preset power values, and the difference between the second preset power value and the power in the characteristic parameters is less than or equal to the second preset power difference value.
[0124] For example, the plurality of RF modules 10 include a first RF module 10a, a second RF module 10b, a third RF module 10c, and a fourth RF module 10d. The processor 40 is electrically connected to the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d. The processor 40 receives the power magnitudes sent by the calculation unit 12 of the first RF module 10a, the calculation unit 12 of the second RF module 10b, the calculation unit 12 of the third RF module 10c, and the calculation unit 12 of the fourth RF module 10d.
[0125] The first RF module 10a is electrically connected to the first antenna radiator 31 via the first RF front-end circuit 20, and the first antenna radiator 31 is located at the top frame 321 of the electronic device 1000. The second RF module 10b is electrically connected to the second antenna radiator 32 via the second RF front-end circuit 20, and the second antenna radiator 32 is located at the bottom frame 323 of the electronic device 1000. The third RF module 10c is electrically connected to the third antenna radiator 33 via the third RF front-end circuit 20, and the third antenna radiator 33 is located at the first side frame 322 of the electronic device 1000. The fourth RF module 10d is electrically connected to the fourth antenna radiator 34 via the fourth RF front-end circuit 20, and the fourth antenna radiator 34 is located at the second side frame 324 of the electronic device 1000.
[0126] If the power received by the calculation unit 12 of the third RF module 10c is less than the respective second preset power value, and the difference between the second preset power value and the power is less than or equal to the second preset power difference. The power received by the calculation unit 12 of the first RF module 10a, the calculation unit 12 of the second RF module 10b, and the calculation unit 12 of the fourth RF module 10d is equal to or substantially equal to the respective second preset power value. This indicates that the first side frame 322 is held by the hand (for example, held by the left hand), and at this time, the other antennas of the top frame 321, the second side frame 324, and the bottom frame 323 can be switched to work.
[0127] If the power received by the calculation unit 12 of the fourth RF module 10d is less than the respective second preset power value, and the difference between the second preset power value and the power is less than or equal to the second preset power difference. The power received by the calculation unit 12 of the first RF module 10a, the calculation unit 12 of the second RF module 10b, and the calculation unit 12 of the third RF module 10c is equal to or substantially equal to their respective second preset power values. This indicates that the second side frame 324 is held by the hand (for example, held by the right hand), and at this time, the other antennas of the top frame 321, the first side frame 322, and the bottom frame 323 can be switched to work.
[0128] If the power received by the calculation unit 12 of the first RF module 10a and the second RF module 10b is less than their respective second preset power values, and the difference between the second preset power value and the power is less than or equal to the second preset power difference. The power received by the calculation unit 12 of the third RF module 10c and the calculation unit 12 of the fourth RF module 10d is equal to or substantially equal to their respective second preset power values. This indicates that the top frame 321 and the bottom frame 323 are held by the hands (for example, held in horizontal mode with both hands), and at this time, the other antennas of the first side frame 322 and the second side frame 324 can be switched to work.
[0129] In this embodiment, the second preset power value is the power of the electronic device 1000 in the working frequency band in free space. The free space refers to the state where the electronic device 1000 is not provided with a protective case and is not held. The second preset power value can be a pre-stored value, or a theoretical power value sent when the base station side calls the radio frequency system 100 on the electronic device 1000 side.
[0130] The present application does not specifically limit the second preset power difference value. For example, the second preset power difference value includes but is not limited to 1 dBm, 2 dBm, 3 dBm, 4 dBm, 5 dBm, 6 dBm, 7 dBm, 8 dBm, etc.
[0131] The specific circuit architecture of the RF module 10 in the present application is illustrated below with reference to the accompanying drawings.
[0132] Optional, see Fig.11 As mentioned above, the RF system 100 includes a RF front-end circuit 20. The RF front-end circuit 20 is electrically connected to the parameter acquisition unit 11 and the calculation unit 12. The RF front-end circuit 20 is configured to send the characteristic parameters of the RF signal to the parameter acquisition unit 11, and receive the first target instruction signal from the calculation unit 12 when the state of the electronic device 1000 is the first target state.
[0133] In a first optional implementation, when the computing unit 12 identifies that the state of the electronic device 1000 is the first target state, it generates a first target command signal and sends the first target command signal to the RF front-end circuit 20 to control the RF front-end circuit 20 to operate in the first target operating mode. The first target operating mode includes but is not limited to a low power consumption mode and a fast response mode. Fig.11 Here, g2 represents the first target command signal.
[0134] See also Fig.11 The RF system 100 further includes a RF transceiver unit 60. The RF transceiver unit 60 is electrically connected to the RF front-end circuit 20. The RF transceiver unit 60 is configured to send a first control instruction to the RF front-end circuit 20 according to the state of the electronic device 1000 not being the first target state. Fig.11 Here, g1 represents the first control instruction.
[0135] When the calculation unit 12 identifies that the state of the electronic device 1000 is not the first target state, the RF transceiver unit 60 is configured to send a first control instruction to the RF front-end circuit 20 according to the state of the electronic device 1000 is not the first target state, so as to control the RF front-end circuit 20 to operate in the third target operating mode. The third target operating mode is the operating state of the RF front-end circuit 20 when the electronic device 1000 is in a normal moving state.
[0136] Optionally, the first target operating mode includes a low power consumption mode. Specifically, in the first target operating mode, the power consumption of the power amplifier of the RF front-end circuit 20 is less than or equal to the first preset power consumption. This application does not make specific limitations on the first preset power consumption. Among them, the power consumption of the power amplifier of the RF front-end circuit 20 working in the first target operating mode is less than the power consumption of the power amplifier of the RF front-end circuit 20 working in the third target operating mode.
[0137] Optionally, the first target operating mode includes a fast response mode. Specifically, the response time of the power amplifier in the first target operating mode is less than or equal to the first preset response time. The present application does not make specific limitations on the first preset response time. Among them, the preset response time of the RF front-end circuit 20 operating in the first target operating mode is less than the preset response time of the RF front-end circuit 20 operating in the third target operating mode.
[0138] Generally, when the electronic device 1000 is in a normal moving state, for example, when the moving speed of the electronic device 1000 is relatively low or stationary, the electronic device 1000 does not need to frequently switch between multiple base stations, the relative position between the electronic device 1000 and the base station remains basically unchanged or changes little, and the direction (power direction) of the wireless signal transmitted by the electronic device 1000 remains basically unchanged or the rate of change is very small.
[0139] When the electronic device 1000 is in a high-speed moving state, for example, in high-speed rail mode, subway mode and high-speed mode, the electronic device 1000 needs to quickly switch to interact with different base stations. The relative position between the electronic device 1000 and the same base station varies greatly. The direction (power direction) of the wireless signal transmitted by the electronic device 1000 needs to be quickly switched to ensure that the direction in which the electronic device 1000 transmits the wireless signal is relative to the direction of the base station, thereby improving the signal connection quality to ensure that the electronic device 1000 still has a high communication quality in a high-speed moving state. Based on this, the RF transceiver unit and the RF front-end circuit 20 both need to operate in a high-frequency switching mode, resulting in large power consumption of the RF transceiver unit and the RF front-end circuit 20, and a rapid temperature rise. Excessive temperature has a greater impact on the performance and accuracy of the RF device. Therefore, in this embodiment, by switching the RF front-end circuit 20 to operate in a low power consumption mode when it is recognized that the electronic device 1000 is in a high-speed moving state, further, the power amplifier in the RF front-end circuit 20 is controlled to switch to a low power consumption mode to avoid the problem of unstable performance and inaccurate accuracy caused by excessive temperature of the power amplifier.
[0140] In this embodiment, when the electronic device 1000 is in the first target state, feedback is given to the RF front-end circuit 20, so that the RF front-end circuit 20 operates in the first target operating mode, and the RF front-end circuit 20 operates in a low power consumption mode or a fast response mode to form a closed-loop adjustment mode. Compared with the sensor detection method in the prior art, this closed-loop adjustment mode has a faster response.
[0141] As mentioned above, see Fig.12 The RF system 100 includes a RF transceiver unit 60. The RF transceiver unit 60 is electrically connected to the RF front-end circuit 20. The RF transceiver unit 60 is used to send a RF signal to the RF front-end circuit 20.
[0142] Optionally, when the computing unit 12 identifies that the state of the electronic device 1000 is the first target state, it generates a first target command signal and sends the first target command signal to the RF transceiver unit 60 to control the RF transceiver unit 60 to operate in a fourth target operating mode. The fourth target operating mode includes but is not limited to a low power consumption mode and a fast response mode.
[0143] When the calculation unit 12 recognizes that the state of the electronic device 1000 is not the first target state, the calculation unit 12 controls the radio frequency transceiver unit 60 to operate in the fifth target operating mode.
[0144] Optionally, the fourth target operating mode is a low power consumption mode. Specifically, the power consumption of the RF transceiver unit 60 in the fourth target operating mode is less than or equal to the second preset power consumption. The present application does not specifically limit the second preset power consumption. Among them, the power consumption of the RF transceiver unit 60 working in the fourth target operating mode is less than the power consumption of the RF transceiver unit 60 working in the fifth target operating mode.
[0145] Optionally, the fourth target operating mode is a fast response mode. Specifically, the response time of the RF transceiver unit 60 in the fourth target operating mode is less than or equal to the second preset response time. The present application does not specifically limit the second preset response time. Among them, the preset response time of the RF transceiver unit 60 working in the fourth target operating mode is less than the preset response time of the RF transceiver unit 60 working in the fifth target operating mode.
[0146] When the electronic device 1000 is in a high-speed moving state, the RF transceiver unit 60 needs to operate in a high-frequency switching mode, which results in a large power consumption of the RF transceiver unit 60 and a rapid temperature rise. Excessive temperature has a significant impact on the performance and accuracy of the RF device. Therefore, in this embodiment, the RF transceiver unit 60 is switched to a low power consumption mode upon recognizing that the electronic device 1000 is in a high-speed moving state, so as to avoid the problem of unstable performance and inaccurate accuracy caused by excessive temperature of the RF transceiver unit 60.
[0147] In other embodiments, see Fig.13 When the computing unit 12 identifies that the state of the electronic device 1000 is the first target state, it feeds back to the RF transceiver unit 60, and the RF transceiver unit 60 generates a first target command signal and sends the first target command signal to the RF front-end circuit 20 to control the RF front-end circuit 20 to operate in the first target operating mode. The first target operating mode includes but is not limited to a low power consumption mode and a fast response mode.
[0148] In a second alternative implementation, see Fig.14 The radio frequency module 10 also includes a command conversion unit 13.
[0149] The instruction conversion unit 13 may be in the form of a circuit disposed on the circuit board 600 , or a independently packaged chip, or a chip integrated and packaged together with other circuits.
[0150] See also Fig.14 The instruction conversion unit 13 is electrically connected to the calculation unit 12. The instruction conversion unit 13 is configured to output a first target instruction signal for a first target state according to the state of the electronic device 1000. Fig.14 Where g2 is the first target command signal.
[0151] In an optional example, the calculation unit 12 receives the characteristic parameters from the parameter acquisition unit 11, and identifies whether the state of the electronic device 1000 is the first target state according to the characteristic parameters. If the calculation unit 12 identifies that the state of the electronic device 1000 is the first target state, the calculation unit 12 sends a control instruction to the instruction conversion unit 13 to control the instruction conversion unit 13 to generate a first target instruction signal, and sends the first target instruction signal to the RF front-end circuit 20 to control the RF front-end circuit 20 to operate in the first target operating mode.
[0152] Exemplarily, the first target state includes but is not limited to a high-speed moving state, a protective shell state, and the like.
[0153] Taking the first target state as a high-speed moving state as an example, the first target working mode includes at least one of a high power level mode, a low power consumption mode, a fast response mode, a frequency deviation correction mode, and the like.
[0154] In an exemplary embodiment, the output end of the instruction conversion unit 13 is electrically connected to a control end of the power amplifier to control the power amplifier to switch to a working mode with a higher power level (higher gain level) to increase the gain level when the electronic device 1000 is in a high-speed moving state.
[0155] In another exemplary embodiment, the output end of the instruction conversion unit 13 is electrically connected to a control end of the power amplifier to control the power amplifier to switch to a lower power consumption operating mode, so as to reduce the power consumption of the power amplifier when the electronic device 1000 is in a high-speed moving state, so as to support the power amplifier to have a faster response speed.
[0156] In another exemplary embodiment, the output end of the instruction conversion unit 13 is electrically connected to a control end of the power amplifier to control the power amplifier to switch to a working mode with a faster response speed, so that the power amplifier has a faster response speed when the electronic device 1000 is in a high-speed moving state.
[0157] In another exemplary embodiment, the RF front-end circuit 20 also includes a frequency deviation correction unit, and the output end of the instruction conversion unit 13 is electrically connected to the frequency deviation correction unit to control the frequency deviation correction unit to switch to a frequency deviation correction mode to correct the electronic device 1000 when it is in a high-speed moving state.
[0158] Taking the protective shell state as an example, the first target state includes at least one of a high power level mode, a low power consumption mode, and the like.
[0159] In an exemplary embodiment, the output end of the instruction conversion unit 13 is electrically connected to a control end of the power amplifier to control the transmission power of the power amplifier to increase the target power value to compensate for the power reduction caused by the electronic device 1000 being in a protective shell state.
[0160] Optionally, the first target command signal may be a command signal that complies with the MIPI interface protocol. Generally, the interface of the power amplifier adopts the MIPI interface standard.
[0161] In this embodiment, the calculation unit 12 in the RF module 10 is designed to directly control the output end of the instruction conversion unit 13 to output the first target instruction signal to form a self-closed loop feedback loop. This self-closed loop feedback loop does not need to pass through the first processor, nor does it need to pass through the RF transceiver unit 60. This embodiment provides a self-closed loop feedback loop with fewer devices, shorter paths, and faster response speed, which is conducive to accurate control without occupying the resources of the first processor and the RF transceiver unit 60.
[0162] As mentioned above, see Fig.15 The radio frequency system 100 also includes a radio frequency transceiver unit 60.
[0163] The RF transceiver unit 60 may be in the form of a circuit disposed on the circuit board 600, or an independently packaged chip, or a chip packaged together with other circuits, etc. The RF transceiver unit 60 may also be referred to as a RF transceiver unit 60, a RF transceiver chip, etc.
[0164] The RF system 100 further includes a RF front-end circuit 20. The RF front-end circuit 20 is electrically connected to the RF transceiver unit 60. The RF front-end circuit 20 is used to receive a RF signal from the RF transceiver unit 60, and the RF signal may also be referred to as a transceiver signal.
[0165] The RF front-end circuit 20 is electrically connected to the parameter acquisition unit 11 and the instruction conversion unit 13. The RF front-end circuit 20 is configured to send the characteristic parameters of the RF signal to the parameter acquisition unit 11, and receive the first target instruction signal from the instruction conversion unit 13 when the state of the electronic device 1000 is the first target state.
[0166] Further exemplarily, the RF transceiver unit 60 is electrically connected to the RF front-end circuit 20 to send the modulated RF signal to the RF front-end circuit 20, which is then transmitted through the antenna radiator after being amplified and processed by the RF front-end circuit 20, or the RF transceiver unit 60 receives the RF signal through the antenna radiator and filtered by the RF front-end circuit 20.
[0167] There is also an instruction transmission route between the RF transceiver unit 60 and the RF front-end circuit 20, and the instruction transmission route is used to transmit the first control instruction generated by the RF transceiver unit 60 to the RF front-end circuit 20 to control the relevant components in the RF front-end circuit 20 to optimize the mode according to the state of the electronic device 1000.
[0168] Exemplarily, the instruction transmission route is used to transmit the first control instruction generated by the radio frequency transceiver unit 60 to the power amplifier.
[0169] Optionally, the RF transceiver unit 60 is electrically connected to the computing unit 12. When the computing unit 12 obtains characteristic parameters of the RF front-end circuit 20 and determines that the state of the electronic device 1000 is the first target state based on the characteristic parameters, it sends a first instruction to the instruction conversion unit 13, and controls the instruction conversion unit 13 to send a first target instruction signal to the RF front-end circuit 20, and controls the RF front-end circuit 20 to switch to a working mode for the first target state (for example, a high-speed rail mode); at the same time, it sends a second instruction to the RF transceiver unit 60, and the RF transceiver unit 60 does not send the first control instruction to the RF front-end circuit 20 according to the second instruction.
[0170] When the calculation unit 12 obtains the characteristic parameters of the RF front-end circuit 20 and determines that the state of the electronic device 1000 is not the first target state based on the characteristic parameters, the first instruction is not sent to the instruction conversion unit 13, and the instruction conversion unit 13 does not send the first target instruction signal to the RF front-end circuit 20; at the same time, the second instruction is not sent to the RF transceiver unit 60, so that the RF transceiver unit 60 sends the first control instruction to the RF front-end circuit 20, and the RF front-end circuit 20 operates in the normal working mode (that is, the aforementioned third target working mode) according to the first control instruction.
[0171] Fig.15 Where g2 is the first target command signal. Fig.15 The g1 in is the first control instruction.
[0172] Optionally, the first control instruction may be a command signal that complies with the MIPI interface protocol.
[0173] In other words, there are two paths for the RF front-end circuit 20 to receive the target command signal. When the state of the electronic device 1000 is not the first target state, the path is from the RF transceiver unit 60 to the RF front-end circuit 20. When the state of the electronic device 1000 is the first target state, the path is from the command conversion unit 13 to the RF front-end circuit 20.
[0174] For another example, see Fig.16 , the RF transceiver unit 60 is electrically connected to the instruction conversion unit 13. There is no direct instruction transmission route between the RF transceiver unit 60 and the RF front-end circuit 20. A direct instruction transmission route is provided between the RF transceiver unit 60 and the instruction conversion unit 13.
[0175] The RF transceiver unit 60 is configured to send a first control instruction to the instruction conversion unit 13 .
[0176] The instruction conversion unit 13 is configured to convert the first control instruction into the first target instruction signal according to the movement state of the electronic device 1000 being the first target state, and transmit the first target instruction signal to the RF front-end circuit 20 to control the relevant components in the RF front-end circuit 20 to optimize the mode according to the state of the electronic device 1000. In other words, in this embodiment, the instruction conversion unit 13 changes the first control instruction into the first target instruction signal.
[0177] The instruction conversion unit 13 is configured to transmit the first control instruction to the RF front-end circuit 20 according to the movement state of the electronic device 1000 is not the first target state. In other words, in this embodiment, the instruction conversion unit 13 does not modify the first control instruction.
[0178] In other words, the RF front-end circuit 20 is further configured to receive the first control instruction from the instruction conversion unit 13 when the state of the electronic device 1000 is not the first target state.
[0179] In this embodiment, the RF front-end circuit 20 receives the target command signal through a transmission line, which is from the RF transceiver unit 60 and the command conversion unit 13 to the RF front-end circuit 20. Whether the state of the electronic device 1000 is in the first target state, the same command line is shared. However, when the state of the electronic device 1000 is in the first target state, the command conversion unit 13 changes the first control command sent by the RF transceiver unit 60, so that the RF front-end circuit 20 switches to a working mode suitable for the first target state.
[0180] See also Fig.17 The parameter acquisition unit 11 acquires the characteristic parameters in the RF front-end circuit 20 in a manner including but not limited to acquiring through the coupler 21 .
[0181] The coupler 21 is also a power distribution component. In the microwave system, the coupler 21 divides one microwave power into several paths in proportion, and then extracts a small portion of the signal from the wireless signal trunk channel. The coupler 21 includes but is not limited to a directional coupler 21, a power divider, and a microwave branching device.
[0182] In an alternative embodiment, see Fig.17 , the RF front-end circuit 20 includes a coupler 21. In other words, the coupler 21 is built into the RF front-end circuit 20 chip and has an external output port.
[0183] The coupler 21 is electrically connected to the parameter acquisition unit 11. Further, an output port of the coupler 21 is electrically connected to the parameter acquisition unit 11. The coupler 21 is configured to couple the RF signal in the RF front-end circuit 20 to the parameter acquisition unit 11.
[0184] In another optional implementation, the RF module 10 further includes a coupler 21. In other words, the coupler 21 is built outside the RF front-end circuit 20 chip.
[0185] The coupler 21 is electrically connected to the parameter acquisition unit 11 and the RF front-end circuit 20. Further, an input end of the coupler 21 is electrically connected to the RF front-end circuit 20, and an output end of the coupler 21 is electrically connected to the parameter acquisition unit 11. The coupler 21 is configured to couple the RF signal in the RF front-end circuit 20 to the parameter acquisition unit 11.
[0186] Optional, see Fig.17 , the RF front-end circuit 20 includes a power amplifier 22 .
[0187] The power amplifier 22 is electrically connected to the instruction conversion unit 13. The power amplifier 22 is configured to operate in a first target operation mode according to a first target instruction signal output by the instruction conversion unit 13.
[0188] Optionally, the first target operating mode includes a fast response mode. In the first target operating mode, the response time of the power amplifier 22 is less than or equal to a preset response time.
[0189] Further optionally, the response time of the power amplifier 22 in the first target operating mode is shorter than the response time when the power amplifier 22 receives the first control instruction output by the instruction conversion unit 13 or the RF transceiver unit 60 (ie, in the third target operating mode).
[0190] When the electronic device 1000 is in a high-speed mobile state, for example, in a high-speed rail mode, a subway mode, and a high-speed mode, the electronic device 1000 needs to quickly switch to interact with different base stations, and the relative position between the electronic device 1000 and the same base station varies greatly, and the direction (power direction) in which the electronic device 1000 transmits wireless signals needs to be quickly switched. In this embodiment, by switching the RF front-end circuit 20 to operate in a fast response mode when it is recognized that the electronic device 1000 is in a high-speed mobile state, further, the power amplifier 22 in the RF front-end circuit 20 is controlled to switch to a fast response mode, so as to ensure that the direction in which the electronic device 1000 transmits wireless signals is relative to the direction in which the base station is located, thereby improving the signal connection quality, so as to ensure that the electronic device 1000 still has a high communication quality in a high-speed mobile state.
[0191] The present application does not make any specific limitation on the specific response time and specific response speed in the fast response mode, and the system efficiency in the high-speed moving state is improved by, for example, the response time and response speed of the RF front-end circuit 20.
[0192] Optionally, the first target operating mode includes a low power consumption mode of the power amplifier 22. In the first target operating mode, the power consumption of the power amplifier 22 is less than or equal to a preset power consumption.
[0193] Further optionally, the power consumption of the power amplifier 22 in the first target operating mode is less than the power consumption when the power amplifier 22 receives the first control instruction output by the instruction conversion unit 13 or the RF transceiver unit 60 (ie, in the third target operating mode).
[0194] The RF module 10 reversely controls the RF front-end circuit 20 to achieve better performance by detecting the size and changes of the characteristic parameters of the RF front-end circuit 20. It can also parse the input MIPI instructions (first control instructions) and then output new MIPI instructions (first target instruction signal) to control the RF front-end circuit 20 to improve the RF performance.
[0195] Optionally, the parameter acquisition unit 11 includes but is not limited to a power detection module. The input power of the power amplifier 22 is detected and amplified to finally obtain the size of the input power. The instruction conversion unit 13 is used to parse the input MIPI instruction (first control instruction) and output a new instruction (first target instruction signal) or transmit the input instruction (first control instruction). The calculation unit 12 is used to control the obtained MIPI instruction (first control instruction), calculate and process the obtained power, etc., and finally output the instruction that needs to be modified (first target instruction signal).
[0196] See also Fig.18 The parameter acquisition unit 11 also includes but is not limited to a feedback gain circuit. The parameter acquisition unit 11 includes a detector 111 and a low noise amplifier 112 .
[0197] The detector 111 is electrically connected to the coupler 21. The detector 111 is configured to obtain a detection signal from the RF signal of the transmission path of the RF front-end circuit 20. The detector 111 is also called a phase detector or a demodulator, and is used to extract the original information signal from the modulated signal.
[0198] The low noise amplifier 112 is electrically connected to the detector 111 and the calculation unit 12 . The low noise amplifier 112 is configured to amplify the detection signal, obtain the characteristic parameter from the amplified detection signal, and send the characteristic parameter to the calculation unit 12 .
[0199] The feedback gain circuit is used to monitor the characteristics of the output signal, including power, spectrum, error vector magnitude (EVM), etc., to ensure that the transmitted signal meets the expected standards and specifications; through feedback, the nonlinear distortion of the RF power amplifier 22 (PA) can be detected and compensated to improve the linearity of the overall system; the pre-distortion algorithm can also be adjusted according to the feedback signal to compensate for the nonlinear distortion; by monitoring the feedback signal, the transmit power can be adjusted in real time to keep it within the specified range.
[0200] The present application proposes a framework scheme based on the state identification of the RF module 10 and the closed-loop feedback loop. The RF module 10 can couple the power from the coupler 21 of the RF front-end circuit 20 to the power detection module (parameter acquisition unit 11). The power detection module (parameter acquisition unit 11) can parse the carried power to obtain key parameters such as size and phase and provide them to the calculation unit 12 of the RF module 10 to realize state identification; when the state of the electronic device 1000 is identified as the first target state, the parameters to be adjusted are directly converted into corresponding instructions (first target instruction signals) through the instruction conversion unit 13 of the MIPI instruction (first control instruction) and given to the RF front-end circuit 20 for direct adjustment, thereby realizing efficient and fast self-closed-loop processing.
[0201] Optional, see Fig.19 The RF system 100 further includes a modem 70. The modem 70 is electrically connected between the processor 40 and the RF transceiver unit 60. The modem 70 sends the modulated signal to the RF transceiver unit 60 under the action of the processor 40.
[0202] The RF system 100 provided in the present application implements a full closed-loop process, and the state is directly identified through the detection of the RF front-end circuit 20 and submitted to the first processor (such as the aforementioned processor 40) to directly call the optimization scheme. The traditional scheme uses sensors to collect information only, and specifically requires the first processor to realize identification, but the RF module 10 of the present application does not require sensors and can also reduce the power consumption calculated by the first processor, and realizes state identification through the low-power consumption calculation unit 12 of the RF module 10. No additional sensors are required for processing (the time is generally very long), and a closed loop is directly realized between the RF front-end circuit 20 and the RF transceiver unit 60. By combining the RF module 10 with the RF front-end circuit 20, accurate identification of the state is realized and closed-loop performance optimization is directly realized.
[0203] See also Fig. 20 The present application also provides a method for identifying the state of an electronic device 1000. The method includes but is not limited to the following steps. The following steps can be combined with reference Figures 1 to 19 .
[0204] Step S100: Acquire characteristic parameters of the radio frequency signal transmitted by the radio frequency front-end circuit 20. The characteristic parameters are used to characterize at least one of the power size and the power direction of the radio frequency signal.
[0205] The characteristic parameters include current, voltage, power, and other characteristic quantities that can characterize the magnitude and direction of power. The characteristic quantity can be an analog signal or a digital signal.
[0206] The characteristic parameter is used to characterize at least one of the power size and power direction of the radio frequency signal. Since the power of the radio frequency signal is a vector, the power size, power value change, and power direction change can be obtained to identify the state of the electronic device 1000.
[0207] The specific structure of the RF front-end circuit 20 may refer to the above description, and the specific implementation method of obtaining the characteristic parameters may refer to the above implementation method.
[0208] Step S200: determining the state of the electronic device 1000 according to the characteristic parameter. The state of the electronic device 1000 includes the movement state of the electronic device 1000 and / or the state of the peripheral environment where the electronic device 1000 is located.
[0209] Exemplarily, the calculation unit 12 determines the movement state of the electronic device 1000 according to the change rate and change rule of the characteristic parameter. The movement state of the electronic device 1000 includes but is not limited to the electronic device 1000 being in a high-speed movement state, and the corresponding scenes include but are not limited to subway mode, high-speed rail mode, highway mode, etc.
[0210] Exemplarily, the peripheral environment state of the electronic device 1000 includes but is not limited to a protective case state, a basement state, an elevator state, a handheld state, etc.
[0211] In general technology, the high-speed moving state of the electronic device 1000 needs to be detected by sensors, etc. The sensors feed back the detection results to the first processor (AP) in the electronic device 1000, and the first processor optimizes and regulates the parameters of the RF front-end circuit 20 by issuing control instructions through the modem and the RF transceiver unit 60. The state identification of the electronic device 1000 requires calling the sensor and performing data processing through the first processor (AP). The time difference of the sensor's identification is obviously not conducive to scene optimization. The entire response process is relatively long, and the response time is too long; it also occupies the resources of the first processor (AP).
[0212] The embodiment of the present application uses the characteristic parameters of the radio frequency signal of the radio frequency front-end circuit 20 collected by the radio frequency system 100, and determines the movement state of the electronic device 1000 and / or the state of the peripheral environment in which the electronic device 1000 is located according to the size and change of the characteristic parameters, without calling sensors. This can not only reduce the setting of sensors, but also shorten the recognition response time, which is conducive to realizing closed-loop precise control and improving the state recognition capability of the electronic device 1000.
[0213] Step S200: Determine the state of the electronic device 1000 according to the characteristic parameter. This includes at least one of the following situations:
[0214] In a first optional implementation, it is determined that the moving state of the electronic device 1000 is a high-speed moving state based on the change rate of the characteristic parameter being greater than or equal to a preset change rate.
[0215] It should be noted that the characteristic parameters include the power of the radio frequency signal, which is a vector, and the power of the vector includes the power magnitude and the power direction. Among them, the power magnitude is the power amplitude. The power direction can be a power angle or a phase. The power magnitude and the power direction can comprehensively characterize the magnitude of the vector power of the radio frequency signal. For example, when the power magnitude remains unchanged, and the power direction of the radio frequency signal transmitted by the electronic device 1000 corresponds to the direction of the base station, the vector power of the electronic device 1000 in the working frequency band is relatively large. When the power magnitude remains unchanged, and the power direction of the radio frequency signal transmitted by the electronic device 1000 has a certain angle with the direction of the base station, the vector power of the electronic device 1000 in the working frequency band is slightly smaller. When the power magnitude remains unchanged, and the power direction of the radio frequency signal transmitted by the electronic device 1000 is opposite to the direction of the base station, the vector power of the electronic device 1000 in the working frequency band is extremely small.
[0216] Generally, when the electronic device 1000 is in a normal moving state, for example, when the moving speed of the electronic device 1000 is relatively low or stationary, the electronic device 1000 does not need to frequently switch between multiple base stations, the relative position between the electronic device 1000 and the base station remains basically unchanged or changes little, and the direction (power direction) of the radio frequency signal transmitted by the electronic device 1000 remains basically unchanged or changes very little.
[0217] When the electronic device 1000 is in a high-speed moving state, for example, in high-speed rail mode, subway mode and high-speed mode, the electronic device 1000 needs to quickly switch to interact with different base stations. The relative position between the electronic device 1000 and the same base station varies greatly. The direction (power direction) of the wireless signal transmitted by the electronic device 1000 needs to be quickly switched to ensure that the direction in which the electronic device 1000 transmits the wireless signal is relative to the direction of the base station, thereby improving the signal connection quality to ensure that the electronic device 1000 still has a high communication quality in a high-speed moving state.
[0218] The specific speed of the high-speed moving state described in this application is not specifically limited. For example, the high-speed moving state is that the electronic device 1000 is in a high-speed rail operation mode, a subway operation mode, or a highway operation mode. For example, the moving speed of the high-speed moving state is greater than or equal to 60 km / h. The normal moving state refers to a moving speed of less than 60 km / h.
[0219] Among them, the rate of change of the characteristic parameter includes but is not limited to the rate of change of the power direction. The electronic device 1000 can determine the preferred signal transceiving direction according to the received signal strength indication signal (RSSI, Received Signal Strength Indication). Generally, the preferred signal transceiving direction corresponds to the base station direction. Since the electronic device 1000 is in a high-speed mobile state, the electronic device 1000 needs to quickly switch to interact with different base stations, and the relative position between the electronic device 1000 and the same base station changes greatly, so the preferred signal transceiving direction of the electronic device 1000 changes significantly faster than the preferred signal transceiving direction in the normal mobile state. For example, when the electronic device 1000 is in a high-speed mobile state, taking the base station coverage radius of 1Km as an example, the power direction of the electronic device 1000 may need to be switched once within a few seconds or tens of seconds. For the electronic device 1000 in a normal mobile state, a switch of the power direction of the electronic device 1000 is much longer than 1 minute.
[0220] This application does not make any specific limitation on the preset change rate.
[0221] For example, the preset change rate is 1 time / 1 minute (this data is only an example).
[0222] The calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a high-speed moving state according to the change rate of the power direction being greater than or equal to 1 time / 1 minute.
[0223] The calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a normal moving state according to the change rate of the power direction being less than 1 time / 1 minute.
[0224] In other words, when the electronic device 1000 is in the high-speed rail motion mode, the interaction distance between the electronic device 1000 and the base station changes rapidly during the rapid movement of the high-speed rail. The result of its feedback to the electronic device 1000 is that the power interaction between them changes rapidly, and the power factor coupled to its front end will also change rapidly.
[0225] For another example, the change rule of the power direction includes but is not limited to that the change angle of the power direction within the preset time is greater than or equal to the preset angle. The preset time includes but is not limited to a few seconds or tens of seconds, and the preset angle is greater than or equal to 30°. Generally, since the high-speed rail (taking the high-speed rail mode as an example) passes through one base station at a time, the orientation of the base station relative to the electronic device 1000 changes greatly at different times, so the preferred signal receiving and sending direction of the electronic device 1000 changes greatly, based on which it can be determined that the electronic device 1000 is in a high-speed rail moving state or a normal moving state.
[0226] The calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a high-speed moving state according to the change angle of the power direction being greater than or equal to a preset angle within a preset time.
[0227] The calculation unit 12 is configured to determine that the movement state of the electronic device 1000 is a normal movement state if the change angle of the power direction within the preset time is less than a preset angle.
[0228] In a second optional implementation, it is determined that the moving state of the electronic device 1000 is a high-speed moving state based on the fact that the changing rule of the characteristic parameter complies with a preset changing rule.
[0229] The change rate of the characteristic parameter includes but is not limited to determining that the moving state of the electronic device 1000 is a high-speed moving state when the change rule of the power direction conforms to a preset change rule.
[0230] Specifically, when the electronic device 1000 is in a high-speed mobile state, the electronic device 1000 interacts with multiple base stations in sequence. Taking a high-speed railway as an example, multiple base stations are provided on one side, and the electronic device 1000 interacts with two adjacent base stations in a similar manner. Therefore, when the electronic device 1000 passes through multiple base stations, the change in power direction has a certain periodicity. For example, when the electronic device 1000 interacts with the first base station, the power direction of the electronic device 1000 is first 30° in the upper left corner, then switches to 90° on the left, and then switches to 150° in the lower left corner; when the electronic device 1000 interacts with the second base station, the power direction of the electronic device 1000 switches to 30° in the upper left corner, then switches to 90° on the left, and then switches to 150° in the lower left corner. When the electronic device 1000 interacts with the third base station, the power direction of the electronic device 1000 switches to 30° in the upper left corner, then switches to 90° on the left, and then switches to 150° in the lower left corner. Similarly, of course, the above is just an example. In actual situations, due to the different distances between different base stations and high-speed railways and different weather conditions in different locations, the power direction will change, but there will be a similar change pattern to the above, similar to periodic changes. In normal mobile conditions, there will be no such periodic change rules.
[0231] The present application does not specifically limit the preset change rule. For example, the change rule of the power direction includes but is not limited to the power direction of the electronic device 1000 including the upper left corner, the lower right corner, the upper left corner, the lower right corner, etc.
[0232] The calculation unit 12 is configured to determine that the moving state of the electronic device 1000 is a high-speed moving state according to whether the change rule of the power direction conforms to a preset change rule. For example, the power direction of the electronic device 1000 includes the upper left corner, the lower right corner, the upper left corner, the lower right corner, etc.
[0233] The calculation unit 12 is configured to determine that the movement state of the electronic device 1000 is a normal movement state according to the change rule of the power direction conforming to the preset change rule. The power direction of the electronic device 1000 includes upper left corner, upper left corner, upper left corner, upper left corner, etc.
[0234] In a third optional implementation, the characteristic parameters received by the calculation unit 12 of each of the RF modules 10 are all less than their respective first preset power values, and the difference between the first preset power value and the power in the characteristic parameter is less than or equal to the first preset power difference value. It is determined that the peripheral environment state of the electronic device 1000 is in a protective shell state.
[0235] For example, the plurality of RF modules 10 include a first RF module 10a, a second RF module 10b, a third RF module 10c, and a fourth RF module 10d. The processor 40 is electrically connected to the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d. The processor 40 receives the power magnitudes sent by the calculation unit 12 of the first RF module 10a, the calculation unit 12 of the second RF module 10b, the calculation unit 12 of the third RF module 10c, and the calculation unit 12 of the fourth RF module 10d.
[0236] The first RF module 10a is electrically connected to the first antenna radiator 31 via the first RF front-end circuit 20, and the first antenna radiator 31 is located at the top frame 321 of the electronic device 1000. The second RF module 10b is electrically connected to the second antenna radiator 32 via the second RF front-end circuit 20, and the second antenna radiator 32 is located at the bottom frame 323 of the electronic device 1000. The third RF module 10c is electrically connected to the third antenna radiator 33 via the third RF front-end circuit 20, and the third antenna radiator 33 is located at the first side frame 322 of the electronic device 1000. The fourth RF module 10d is electrically connected to the fourth antenna radiator 34 via the fourth RF front-end circuit 20, and the fourth antenna radiator 34 is located at the second side frame 324 of the electronic device 1000.
[0237] If the characteristic parameters (power levels) received by the calculation units 12 of the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d are all smaller than their respective first preset power values (for example, 20dBm, but not limited to this data), and the difference between the first preset power value and the power level in the characteristic parameter is less than or equal to the first preset power difference value (for example, 4dBm, but not limited to this data).
[0238] The present application does not specifically limit the first preset power difference. Optionally, the first preset power difference may be less than the power difference between a strong signal field and a weak signal field. For example, the power value in a strong signal field is 20 dBm. The power value in a weak signal field is 10 dBm. The first preset power difference is less than 10 dBm. For example, the first preset power difference includes but is not limited to 1 dBm, 2 dBm, 3 dBm, 4 dBm, 5 dBm, 6 dBm, 7 dBm, 8 dBm, etc.
[0239] In this embodiment, the first preset power value is the power of the electronic device 1000 in the working frequency band in free space. The free space refers to the state where the electronic device 1000 is not provided with a protective case and is not held. The first preset power value can be a pre-stored value, or a theoretical power value sent when the base station side calls the radio frequency system 100 on the electronic device 1000 side.
[0240] For example, the first preset power values of the first RF front-end circuit 20 , the second RF front-end circuit 20 , the third RF front-end circuit 20 , and the fourth RF front-end circuit 20 are all 20 dBm.
[0241] For example, the power magnitudes in the respective RF front-end circuits 20 obtained by the calculation units 12 of the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d are 18dBm. The difference between the first preset power value and the power magnitude in the characteristic parameter is 2dBm. The power magnitudes in the respective RF front-end circuits 20 obtained by the calculation units 12 of the first RF module 10a, the second RF module 10b, the third RF module 10c, and the fourth RF module 10d are all less than 20dBm, and the difference is less than 4dBm. The antenna power on each side of the frame of the electronic device 1000 is smaller than the first preset power value, indicating that the electronic device 1000 is in a protective shell state.

This indicates that the first side frame 322 is held by the hand (for example, held by the left hand), and at this time, the other antennas of the top frame 321, the second side frame 324, and the bottom frame 323 can be switched to work.
