Description

Technical Field

[0001] The present application belongs to the field of radio frequency technology, and specifically relates to an electronic device and a control method and device thereof. Background Art

[0002] The electronic device 100' generally has multiple antennas, such as Figure 1 As shown, an electronic device 100' having three antennas is used as an example for explanation, the first antenna 122' is located at the top 102' of the electronic device 100', the second antenna 124' is located at the bottom 104' of the electronic device 100', and the third antenna 126' is located at the side 106' of the electronic device 100'. In some frequency bands, for example: Long-term Evolution band 34 (LTE band 34) and Long-term Evolution band 39 (LTE band 39), the signal only switches between the first antenna 122' and the second antenna 124'. However, in a horizontal screen game scenario, the first antenna 122' and the second antenna 124' will be held frozen at the same time, resulting in poor signal quality of the electronic device 100'. In the related art, in order to solve the problem of poor signal quality in the game scene, a blind antenna cutting strategy is usually used, that is, as long as it is detected that the game scene has been entered, the RF transmission circuit is cut to the third antenna 126'. However, the blind cutting is based on the application layer's determination of whether the game scene has been entered to choose whether to use the third antenna 126'. As a result, when the user is playing the game in a non-horizontal screen scene, the RF transmission circuit is also cut to the third antenna 126'. The performance of the third antenna 126' is much lower than that of the first antenna 122', which results in poor signal quality of the electronic device 100'. Summary of the invention

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0041] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0042] In conjunction with the accompanying drawings, an electronic device and a control method and device thereof provided in an embodiment of the present application are described below through specific embodiments and application scenarios.

[0043] like Figure 2 and Figure 3 As shown, in the first aspect, the embodiment of the present application provides an electronic device 100, including: a radio frequency transmitting circuit 110; an antenna assembly 120, the antenna assembly 120 including a first antenna 122, a second antenna 124 and a third antenna 126; a radio frequency switch 130, connected to the radio frequency transmitting circuit 110 and the antenna assembly 120, the radio frequency switch 130 is used to switch the on and off state of the radio frequency transmitting circuit 110 and the first antenna 122, the second antenna 124 and the third antenna 126; a coupling assembly 140, used to couple the signal on the radio frequency transmitting circuit 110 coupled to the third antenna 126; a receiver 150 cooperates with the third antenna 126, and the receiver 150 is used to receive the signal radiated by the third antenna 126; wherein, when the strength of the received signal received by the first antenna 122 and the second antenna 124 is less than or equal to the first threshold, the coupling component 140 couples the signal on the RF transmitting circuit 110 to the third antenna 126, and the electronic device 100 determines the state of the RF switch 130 according to the first power of the signal of the receiver 150 to determine the working state of the first antenna 122 and the third antenna 126.

[0044] In an embodiment of the present application, the electronic device 100 includes a radio frequency transmitting circuit 110, an antenna assembly 120 and a radio frequency switch 130. The radio frequency transmitting circuit 110 is connected to the radio frequency switch 130, and the radio frequency switch 130 is connected to the antenna assembly 120. The antenna assembly 120 includes a first antenna 122, a second antenna 124 and a third antenna 126. The radio frequency switch 130 can adjust the on and off state of the radio frequency transmitting circuit 110 and the first antenna 122, the second antenna 124 and the third antenna 126.

[0045] The electronic device 100 further includes a coupling component 140 and a receiver 150. The coupling component 140 cooperates with the RF transmitting circuit 110 and the third antenna 126. The coupling component 140 can couple the signal on the RF transmitting circuit 110 to the third antenna 126. The receiver 150 cooperates with the third antenna 126. The receiver 150 can receive the signal radiated by the third antenna 126. That is, after the coupling component 140 couples the signal on the RF transmitting circuit 110 to the third antenna 126, the third antenna 126 can radiate the signal, and the receiver 150 receives the signal radiated by the third antenna 126. The first power of the signal on the receiver 150 can reflect the current performance of the third antenna 126.

[0046] When the electronic device 100 uses the first antenna 122 and the second antenna 124 to communicate, if the strength of the received signal received by the first antenna 122 and the second antenna 124 is less than or equal to the first threshold, the coupling component 140 couples the signal on the RF transmitting circuit 110 to the third antenna 126, the third antenna 126 radiates the signal, and the receiver 150 receives the signal radiated by the third antenna 126. After that, the electronic device 100 can determine the state of the RF switch 130 according to the first power of the signal on the receiver 150 to determine the working state of the first antenna 122 and the third antenna 126.

[0047] As described above, when the strength of the received signals received by the first antenna 122 and the second antenna 124 is low, the present application detects the performance of the third antenna 126, and determines whether antenna switching and other operations are required based on the performance of the third antenna 126, thereby avoiding the signal quality instability caused by blind cutting of the antenna and improving the signal quality of the electronic device 100.

[0048] The RF switch 130 has multiple RF (Radio Frequency, RF) interfaces, such as Figure 3 As shown, the RF switch 130 has six interfaces (RF1, RF2, RF3, RF4, RF5, RF6), so as to adjust the on-off state of the RF transmitting circuit 110 and the first antenna 122, the second antenna 124 and the third antenna 126.

[0049] The first antenna 122 may be ANT13 , the second antenna 124 may be ANT41 , and the third antenna 126 may be ANT25 .

[0050] The first threshold can be set based on experiments or experience.

[0051] like Figure 3As shown, as a possible implementation, the coupling component 140 includes: a first coupler 142, which cooperates with the RF transmitting circuit 110; a first switch 144, wherein the first end 1442 of the first switch 144 is connected to the first coupler 142, and the second end 1444 of the first switch 144 is connected to the third antenna 126. When the first switch 144 is in a first state, the first coupler 142 and the third antenna 126 are in a conducting state, and when the first switch 144 is in a second state, the first coupler 142 and the third antenna 126 are in an open state; wherein, when the strength of the received signal received by the first antenna 122 and the second antenna 124 is less than or equal to the first threshold, the electronic device 100 controls the first switch 144 to switch to the first state, so that the coupling component 140 couples the signal on the RF transmitting circuit 110 to the third antenna 126.

[0052] In this embodiment, the coupling component 140 includes a first coupler 142 and a first switch 144. The first coupler 142 cooperates with the RF transmitting circuit 110. The first end 1442 of the first switch 144 is connected to the first coupler 142, and the second end 1444 of the first switch 144 is connected to the third antenna 126. The first switch 144 has a first state and a second state. When the first switch 144 is in the first state, the first end 1442 and the second end 1444 are conductive, and the first coupler 142 and the third antenna 126 are in a conductive state. When the first switch 144 is in the second state, the first end 1442 and the second end 1444 are disconnected, and the first coupler 142 and the third antenna 126 are in a disconnected state.

[0053] When the strength of the received signals received by the first antenna 122 and the second antenna 124 is less than or equal to the first threshold, the electronic device 100 controls the first switch 144 to switch to the first state, so that the first end 1442 and the second end 1444 are conductive, and the first coupler 142 and the third antenna 126 are in a conductive state, so that the third antenna 126 can receive the signal on the radio frequency transmitting circuit, thereby radiating the signal, and the receiver 150 can receive the signal radiated by the third antenna 126.

[0054] By switching the state of the first switch 144, the signal of the RF transmitting circuit 110 can be coupled to the third antenna 126 only when the strength of the received signal received by the first antenna 122 and the second antenna 124 is less than or equal to the first threshold, thereby reducing the interference of the third antenna 126 to the signal of the entire electronic device 100 and reducing power consumption.

[0055] Among them, the first switch 144 can have a first end 1442, a second end 1444 and a third end 1446. The first end 1442 is connected to the first coupler 142, the second end 1444 is connected to the third antenna 126, and the third end 1446 is in an open circuit state. When the first switch 144 is in the first state, the first end 1442 and the second end 1444 are connected, and the first coupler 142 and the third antenna 126 are in a conductive state. When the first switch 144 is in the second state, the second end 1444 and the third end 1446 are disconnected, and the first coupler 142 and the third antenna 126 are in an open circuit state.

[0056] The first coupler 142 may be a microstrip coupler, for example, a section of radio frequency impedance line is arranged below the routing of the radio frequency transmitting circuit 110, and coupling of the signal of the transmitting power is achieved through coupling between the impedance line and the radio frequency transmitting circuit 110, and the coupled signal passes through the conductive routing and the first switch 144. When the first switch 144 is in the first state, the coupled signal is connected to the third antenna 126, that is, the signal of the radio frequency transmitting circuit 110 is coupled through the impedance line, and the normal transmission of the signal on the radio frequency transmitting circuit 110 is not affected. Of course, the first coupler 142 may also be other types of couplers.

[0057] The connection between the first switch 144 and the first coupler 142 may be a direct connection or an indirect connection through a wire, and the connection between the first switch 144 and the third antenna 126 may be a direct connection or an indirect connection through a wire.

[0058] like Figure 3 As shown, the first end 1442 is a radio frequency interface (RF1), the second end 1444 is an antenna interface (ANT), and the third end 1446 is a radio frequency interface (RF2).

[0059] like Figure 3 As shown, as a possible implementation, the electronic device 100 further includes: a detection component 160 connected to the receiver 150 and configured to detect a first power of a signal on the receiver 150 .

[0060] Specifically, the electronic device 100 also includes a detection component 160, which is used to detect the first power of the signal on the receiver 150, so that the electronic device 100 can determine the state of the RF switch 130 according to the detection result of the detection component 160 to determine the working state of the first antenna 122 and the third antenna 126.

[0061] like Figure 3As shown, as a possible implementation, the detection component 160 includes: a radio frequency chip 162, used to determine the first power of the signal on the receiver 150; a second coupler 166, cooperating with the radio frequency transmitting circuit 110; a second switch 164, the fourth end 1642 of the second switch 164 is connected to the radio frequency chip 162, the fifth end 1644 of the second switch 164 is connected to the second coupler 166, and the sixth end 1646 of the second switch 164 is connected to the receiver 150. When the second switch 164 is in the third state, the radio frequency chip 162 and the second coupler 166 are in the on state. When the second switch 164 is in the fourth state, the radio frequency chip 162 and the receiver 150 are in the on state. Wherein, when the strength of the received signal received by the first antenna 122 and the second antenna 124 is less than or equal to the first threshold, the second switch 164 is controlled to switch to the fourth state.

[0062] Specifically, the detection component 160 includes a radio frequency chip 162, a second coupler 166 and a second switch 164. The second coupler 166 cooperates with the radio frequency transmitting circuit 110 to couple the signal of the radio frequency transmitting circuit 110 to the radio frequency chip 162. The fourth end 1642 of the second switch 164 is connected to the radio frequency chip 162, the fifth end 1644 of the second switch 164 is connected to the second coupler 166, and the sixth end 1646 of the second switch 164 is connected to the second antenna 124. The second switch 164 has a third state and a fourth state. In the second switch When the second switch 164 is in the third state, the fourth end 1642 and the fifth end 1644 are connected to each other, so that the RF chip 162 and the second coupler 166 are connected to each other. At this time, the RF chip 162 can detect the power of the signal on the RF transmitting circuit 110 to determine the working state of the RF transmitting circuit 110. When the second switch 164 is in the fourth state, the fourth end 1642 and the sixth end 1646 are connected to each other, so that the RF chip 162 and the receiver 150 are connected to each other. At this time, the RF chip 162 can detect the first power of the signal on the receiver 150.

[0063] By switching the state of the second switch 164, the first power of the signal on the receiver 150 can be detected only when the strength of the received signal received by the first antenna 122 and the second antenna 124 is less than or equal to the first threshold, thereby reducing the difficulty of circuit layout and reducing the interface occupancy of the RF chip 162.

[0064] Among them, the second switch 164 can have a fourth end 1642, a fifth end 1644 and a sixth end 1646, the fourth end 1642 is connected to the RF chip 162, the fifth end 1644 is connected to the second coupler 166, and the sixth end 1646 is connected to the receiver 150. When the second switch 164 is in the third state, the fourth end 1642 and the fifth end 1644 are connected, the RF chip 162 and the second coupler 166 are in a conductive state, the fourth end 1642 and the sixth end 1646 are disconnected, and the RF chip 162 and the receiver 150 are in an open state. When the second switch 164 is in the fourth state, the fourth end 1642 and the fifth end 1644 are disconnected, the RF chip 162 and the second coupler 166 are in an open state, the fourth end 1642 and the sixth end 1646 are connected, and the RF chip 162 and the receiver 150 are in a conductive state.

[0065] like Figure 3 As shown, the fourth end 1642 is an antenna interface (ANT), the fifth end 1644 is a radio frequency interface (RF2), and the sixth end 1646 is a radio frequency interface (RF1).

[0066] The second coupler 166 may be a microstrip coupler or other couplers.

[0067] The connection between the second switch 164 and the RF chip 162 can be direct or indirect via a wire, the connection between the second switch 164 and the second coupler 166 can be direct or indirect via a wire, and the connection between the second switch 164 and the receiver 150 can be direct or indirect via a wire.

[0068] like Figure 2 As shown, as a possible implementation, the first antenna 122 is located at the top 102 or the bottom 104 of the electronic device 100; the second antenna 124 is located at the top 102 or the bottom 104 of the electronic device 100; the third antenna 126 is located between the top 102 and the bottom 104 of the electronic device 100; and at least a portion of the button 108 of the electronic device 100 forms a receiver 150.

[0069] Specifically, the first antenna 122 is located at the top 102 or the bottom 104 of the electronic device 100, the second antenna 124 is located at the top 102 or the bottom 104 of the electronic device 100, and the third antenna 126 is located between the top 102 and the bottom 104 of the electronic device 100. The third antenna 126 can be located at the side 106 of the electronic device 100, so that the first antenna 122, the second antenna 124 and the third antenna 126 are respectively located at different positions of the electronic device 100, thereby reducing the possibility of the first antenna 122, the second antenna 124 and the third antenna 126 being blocked at the same time, thereby improving the stability of the signal of the electronic device 100.

[0070] A portion of the button 108 can form the receiver 150, or the entire button 108 can form the receiver 150. The button 108 itself is a passive device. Therefore, using the button 108 to form the receiver 150 can reduce interference to the receiver 150. The receiver 150 is arranged near the third antenna 126 and in a position that is not easy to hold from the outside. The button 108 near the third antenna 126 can be used as the receiver 150, and the receiver 150 is connected to the detection component 160 through a wire. The button 108 can be a power button or a volume button.

[0071] Of course, in other embodiments of the present application, the receiver 150 may also be a fourth antenna, or at least a portion of the frame of the electronic device 100 , or other passive components on the electronic device 100 .

[0072] In a second aspect, an embodiment of the present application provides a method for controlling an electronic device, which is executed by the electronic device provided in the first aspect. Figure 4 FIG. 1 is a flow chart showing a method for controlling an electronic device according to an embodiment of the present application. Figure 4 As shown, the method includes:

[0073] Step 402: Obtain the strength of the received signals received by the first antenna and the second antenna.

[0074] Specifically, during the process of the electronic device communicating using the first antenna and the second antenna, the strength of the received signal received by the first antenna and the second antenna is monitored, and the strength of the received signal can be determined using the receiving path of the first antenna and the second antenna.

[0075] Step 404: When the strength of the received signals received by the first antenna and the second antenna is less than or equal to the first threshold, couple the signal on the radio frequency transmission circuit to the third antenna.

[0076] Specifically, when the strength of the received signals received by the first antenna and the second antenna is less than or equal to the first threshold, the coupling component can couple the signal on the radio frequency transmitting circuit to the third antenna.

[0077] Step 406: Obtain a first power of a signal on a receiver.

[0078] Specifically, after the signal on the radio frequency transmitting circuit is coupled to the third antenna, the third antenna radiates the signal, the receiver receives the signal radiated by the third antenna, and obtains the first power of the signal of the third antenna received by the receiver.

[0079] Step 408: Determine the state of the radio frequency switch according to the first power to determine the working states of the first antenna and the third antenna.

[0080] Specifically, the state of the radio frequency switch is determined according to the first power of the signal on the receiver, thereby determining the working states of the first antenna and the third antenna.

[0081] In an embodiment of the present application, when the electronic device uses the first antenna and the second antenna to communicate, if the strength of the received signal received by the first antenna and the second antenna is less than or equal to the first threshold, the coupling component couples the signal on the RF transmitting circuit to the third antenna, the third antenna radiates the signal, the receiver receives the signal radiated by the third antenna, determines the first power of the signal on the receiver, and the electronic device determines the state of the RF switch based on the first power to determine the working state of the first antenna and the third antenna.

[0082] As mentioned above, when the strength of the received signals received by the first antenna and the second antenna is low, the present application detects the performance of the third antenna, and determines whether antenna switching and other operations are required based on the performance of the third antenna, thereby avoiding the signal quality instability caused by blind cutting of the antenna and improving the signal quality of the electronic device.

[0083] As a possible implementation, when the strength of the received signal received by the first antenna and the second antenna is less than or equal to the first threshold, the signal on the RF transmitting circuit is coupled to the third antenna, including: when the strength of the received signal received by the first antenna and the second antenna is less than or equal to the first threshold, the transmission power of the signal on the RF transmitting circuit is set to the target power; controlling the first switch to switch to the first state, and controlling the second switch to switch to the fourth state, so that the signal on the RF transmitting circuit is coupled to the third antenna.

[0084] Specifically, when the strength of the received signal received by the first antenna and the second antenna is less than or equal to the first threshold, the signal on the RF transmitting circuit is coupled to the third antenna, including: when the strength of the received signal received by the first antenna and the second antenna is less than or equal to the first threshold, adjusting the transmission power of the signal on the RF transmitting circuit to adjust the signal on the RF transmitting circuit to the target power, controlling the first switch to switch to the first state so that the first coupler and the third antenna are turned on, thereby coupling the signal on the RF transmitting circuit to the third antenna, and controlling the second switch to switch to the fourth state so that the RF chip and the receiver are turned on, and the receiver can receive the signal on the third antenna.

[0085] By adjusting the signal on the radio frequency transmitting circuit to the target power, the signal on the third antenna has a reference standard, so as to improve the accuracy of adjusting the radio frequency switch through the first power.

[0086] The target power may be a maximum power or another power.

[0087] As a possible implementation, the state of the RF switch is determined according to the first power to determine the working states of the first antenna and the third antenna, including: determining the second power of the signal on the third antenna according to the target power; determining the isolation between the third antenna and the receiver according to the second power and the first power; when the isolation is greater than the target isolation, determining the state of the RF switch to make the first antenna and the RF transmitting circuit conductive; when the isolation is less than or equal to the target isolation, determining the state of the RF switch to make the third antenna and the RF transmitting circuit conductive.

[0088] Specifically, according to the first power, the state of the RF switch is determined to determine the working states of the first antenna and the third antenna, including: according to the target power, the second power of the signal generated on the third antenna after coupling is determined, and the isolation between the third antenna and the receiver is determined by the difference between the second power and the first power. When the isolation is greater than the target isolation, it can be considered that the third antenna is currently being held. At this time, the state of the RF switch is determined to make the first antenna and the RF transmitting circuit conductive, and the third antenna is not used, thereby ensuring invalid antenna switching. When the isolation is less than or equal to the target isolation, it can be considered that the third antenna is currently not being held. At this time, the state of the RF switch is determined to make the third antenna and the RF transmitting circuit conductive, thereby improving the signal quality of the electronic device.

[0089] As a possible implementation manner, determining the second power of the signal on the third antenna according to the target power includes: determining a coupling coefficient of a coupling component; and determining the second power according to the target power and the coupling coefficient.

[0090] Specifically, according to the target power, the second power of the signal on the third antenna is determined, including: determining the coupling coefficient of the coupling component, different coupling coefficients of different coupling components are different, and then the second power of the signal on the third antenna can be determined through the target power and the coupling coefficient, thereby ensuring the accuracy of the isolation between the third antenna and the receiver.

[0091] The coupling coefficient depends on the size of the coupler. For example, if an impedance line is used as a coupler, the coupling coefficient depends on the length and width of the impedance line.

[0092] The control method of the electronic device provided in the present application couples the signal of the radio frequency transmitting circuit through a coupling component, couples the signal on the radio frequency transmitting circuit to the third antenna without a receiving path, and then detects the power change of the signal transmitted by the third antenna received by the receiver at all times through the feedback (Feedback Receiver FBRX) interface of the transmitting chip, so as to realize real-time detection of the antenna efficiency change of the third antenna, such as whether it is held. If it is detected that the third antenna is not held and the signal strength of other antennas is relatively poor, the transmission (Transmit, TX) function and the primary receive (Primary Receive, PRX) function are switched to the third antenna. Similarly, the efficiency of any antenna without a receiving path can be detected in real time to evaluate whether to switch the antenna.

[0093] Therefore, the efficiency detection and evaluation of all antennas can be realized without adding additional receiving circuits, and multi-antenna switching among n+x antennas can be realized with only n receiving paths, where n is a positive integer and x is a positive integer. The defect of unstable signal quality caused by blind cutting of antennas is avoided, greatly improving the gaming and communication experience of electronic devices.

[0094] Specifically, an electronic device is illustrated working in the LTE 39 frequency band through the first antenna and the second antenna. When the strength of the received signals of the first antenna and the second antenna is relatively good, the TX of the LTE 39 frequency band is normally switched between the first antenna and the second antenna based on the strength of the received signals of PRX and diversity reception (Discontinuous Reception, DRX). For example, TX and PRX are performed through the first antenna, and DRX is performed through the second antenna. At this time, the first switch is in the second state, and the first coupler and the third antenna are disconnected.

[0095] At a certain moment, the RF chip (Radio Frequency Integrated Circuit, RFIC) detects that the strength of the received signals of PRX and DRX suddenly deteriorates. In many cases, at this time, it will be determined that the electronic device is in a relatively poor signal state, and the power of the signal on the RF transmitting circuit will be adjusted to the maximum power. RFIC can detect the target power at this time through the second coupler, assuming it is P1. Then RFIC controls the first switch to switch to the first state, so that the third antenna is connected to the first coupler, and the coupling coefficient of the coupling component is -20, so the second power coupled to the third antenna at this time is (P1-20).

[0096] After the signal coupled to the third antenna is radiated, the receiver can receive the signal transmitted by the third antenna. The RFIC switches the FBRX to be connected to the receiver through the second switch. At this time, the RFIC can detect the first power P2 of the signal on the receiver. The isolation S between the third antenna and the receiver is obtained by subtracting the first power P2 from the second power. When the third antenna is held by hand, the isolation between the third antenna and the receiver will deteriorate rapidly. What is manifested is that the isolation S becomes larger. In this way, the efficiency of the third antenna can be judged according to the size of the isolation S. Among them, the units of the first power and the second power can be dBm.

[0097] When the PRX and DRX signals are relatively poor at a certain moment, and the isolation S of the third antenna is normal, that is, it is not held by the hand, at this time, the TX and PRX of the LTE 39 frequency band are switched to the third antenna.
