Description

[0001] This application is a divisional application. The application number of the original application is 202011599529.1, and the original application date is December 29, 2020. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and in particular to antenna systems, wireless communication systems, and electronic devices. Background Art

[0003] An electronic device can achieve wireless communication with other devices through one or more antennas disposed therein. Therefore, the antenna plays a very important role in the communication process of the electronic device.

[0004] Generally speaking, the distribution of an antenna's radiation capability in space can be identified by a radiation pattern (also called a gain pattern). Figure 1 FIG. 1 shows a schematic diagram of the directional pattern of an antenna. Figure 1 As shown, the gain of the antenna at different angles is different, with some angles having larger gains and some angles having smaller gains. The greater the gain, the stronger the radiation (such as transmission or reception) capability of the antenna at that angle. Correspondingly, the smaller the gain, the weaker the radiation capability of the antenna at that angle. In this application, the angle at which the gain is much smaller than the maximum gain can be referred to as the "null point of the directional pattern".

[0005] It is understandable that due to the existence of the zero point of the directional diagram, when the direction of the wireless communication signal wave corresponds to the zero point of the directional diagram, the antenna's radiation ability in this direction is weak, so the signal wave reception will have a high bit error rate or even fail to be received normally. Similarly, when it is necessary to transmit the signal at the angle corresponding to the zero point of the directional diagram or other angles near this angle, the signal may not be transmitted normally. As a result, the wireless communication of electronic devices is seriously affected. Summary of the invention

[0006] Embodiments of the present application provide an antenna system, a wireless communication system, and an electronic device. The switching unit provided in the antenna system can be used to flexibly adjust the electrical connection relationship between the antenna pair and the radio frequency module, thereby achieving the effect of reconstructing the antenna pattern, thereby resolving the impact of the zero point of the antenna's inherent pattern on communication. Furthermore, the switching unit provided in the antenna system can also flexibly adjust the electrical connection relationship between the antenna pair and the radio frequency module, thereby achieving the effect of reconstructing the number of antenna workings, thereby improving the throughput in scenarios with high throughput requirements.

[0007] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0008] In a first aspect, a wireless communication system is provided, which is applied to an electronic device, and the wireless communication system includes: a first radio frequency channel. A first antenna unit. A second antenna unit. And a first switching device, which is configured to selectively connect at least one of the first antenna unit and the second antenna unit to the first radio frequency channel. In a first state, the first switching device is configured to connect the first antenna unit and the first radio frequency channel, and the first switching device is also configured to connect the second antenna unit and the first radio frequency channel. In a second state, the first switching device is configured to connect the first antenna unit and the first radio frequency channel, and the second antenna unit and the first radio frequency channel are not connected.

[0009] Based on the scheme, a switching device (such as a first switching device) is provided in the wireless communication system. By controlling the first switching device to be in different working states, the wireless communication system operates in different states (such as a first state or a second state). When the first switching device is in different working states, the RF channel and the antenna unit coupled to the front end and the rear end of the first switching device may have different electrical connection states. For example, in the first state, the first RF channel is coupled to the first antenna unit, and the first RF channel is also coupled to the second antenna unit. For another example, in the second state, the first RF channel is only coupled to the first antenna unit. It can be understood that, since the antenna units coupled to the first RF channel are different in different states, the corresponding radiation patterns of the wireless communication system are also different in different states. Therefore, when the communication in a certain state is blocked due to the existence of the zero point of the pattern, the pattern can be reconstructed by switching the first state to the second state, or switching the second state to the first state, or switching from other states to the first state (or the second state), or switching the first state (or the second state) to other states. It is understandable that in the case of different radiation patterns, the corresponding pattern zero points are also different. Therefore, through pattern reconstruction, the incoming wave direction (or radiation direction) originally at the pattern zero point can no longer correspond to the pattern zero point, thereby improving the communication obstruction problem caused by the pattern zero point. It should be noted that in this example, the first RF channel can correspond to the RF channel RF2 involved in the embodiment.

[0010] In a possible design, in the first state, the signals flowing through the first antenna unit and the second antenna unit are both first signals. In the second state, the signal flowing through the first antenna unit is the second signal, and the second signal does not flow through the second antenna unit. Based on this scheme, an example of signal flow distribution in the first state and the second state is provided. Exemplarily, in the first state, the first switching device connects the first antenna unit and the second antenna unit to the first radio frequency channel. Therefore, in the transmission scenario, the first signal from the first radio frequency channel can flow to the first antenna unit and the second antenna unit for radiation respectively. Correspondingly, in the receiving scenario, the electromagnetic waves received by the first antenna unit and the second antenna unit can also be converted into analog signals (for example, corresponding to one first signal respectively) and transmitted to the first radio frequency channel. Similarly, in the second state, since the first switching device connects the first antenna unit to the first radio frequency channel, and the second antenna unit is not connected to the first radio frequency channel, only the first antenna unit can be used to support the signal transmission of the first radio frequency channel. For example, in the transmission scenario, the first radio frequency channel can send the second signal through the first antenna unit. For another example, in a receiving scenario, the second signal may be generated by the first antenna unit by converting the received electromagnetic wave and transmitted to the first RF channel. In one possible design, in the first state, the RF parameter of the first signal is the first parameter. In the second state, the RF parameter of the second signal is the second parameter, wherein the first parameter and the second parameter are different. Based on this scheme, a scheme for distinguishing the first state from the second state is provided. For example, the first state and the second state can be distinguished by the RF parameter being the first parameter or the second parameter. Furthermore, the electronic device can adjust the current working state to the first state or the second state according to the RF parameter, so as to achieve the effect of improving the RF parameters during the communication process. It can be understood that when the RF parameters are improved, it also means that the communication quality is improved.

[0011] In one possible design, the radio frequency parameters include reference signal received power RSRP and / or bit error rate. Based on this solution, a specific example of radio frequency parameters is provided. For example, the radio frequency parameters may include RSRP, or bit error rate, or RSRP and bit error rate, etc. Of course, in other implementations, the radio frequency parameters may also include more other parameters, such as received signal strength (RSSI), etc. This example does not limit the specific content of the radio frequency parameters.

[0012] In a possible design, the wireless communication system further includes a second radio frequency channel. In the third state, the first switching device is configured to conduct the first antenna unit and the first radio frequency channel, and the first switching device is further configured to conduct the second antenna unit and the second radio frequency channel, the signal flowing through the first antenna unit is the third signal, and the signal flowing through the second antenna unit is the fourth signal. Based on this scheme, a universal extension of the wireless communication system is provided. It can be understood that in the above-mentioned design, the change of the coupling relationship of the first radio frequency channel in the wireless system and the corresponding effect are described. It can be understood that more radio frequency channels can be included in the wireless communication system, for example, the second radio frequency channel can be included. The second radio frequency channel can correspond to the radio frequency channel RF1 involved in the following embodiment. In the third state, since the first switching device couples the first radio frequency channel with the first antenna unit and couples the second radio frequency channel with the second antenna unit, when the first radio frequency channel and the second radio frequency channel operate in the same frequency band, then for the receiving scenario, the electronic device can simultaneously receive two signals (such as the third signal and the fourth signal) through the first antenna unit and the second antenna unit, so compared with the ordinary scenario where only one signal can be received, the throughput can be significantly improved. It should be noted that in this scenario, the third signal and the fourth signal can correspond to two signals with the same frequency band. The transmission scenarios are similar, so similar effects can be achieved. It can be understood that the above description is based on the premise that the first RF channel and the second RF channel operate in the same frequency band. It can be understood that the first RF channel and the second RF channel can also be transmission channels corresponding to two parallel data in a multi-input and output scenario, or two transmission channels corresponding to synchronously transmitted data in a carrier aggregation scenario. The effects that can be achieved are similar, that is, the number of signal streams can be significantly increased, thereby improving communication quality.

[0013] In a second aspect, a foldable electronic device is provided, comprising: a flexible display screen, and a wireless communication system as described in any one of the first aspect and possible designs thereof. The foldable electronic device comprises a first folded state and a second folded state, and in the first folded state, the wireless communication system is in the first state. In the first folded state, the wireless communication system is in the second state.

[0014] Based on this solution, an application of the wireless communication system as described in the first aspect in a foldable electronic device is provided. Among them, the flexible display screen can be a foldable display screen, which can include one or more foldable display screens, or can include at least two non-foldable display screens at the same time. Exemplarily, the various states provided in the first aspect and its possible designs can correspond to different folding states in the foldable electronic device, thereby achieving different forms (such as folded state and unfolded state) by reconstructing the number of antenna units to solve the problem of communication obstruction caused by the zero point of the directional pattern, thereby achieving the effect of improving the communication quality.

[0015] In one possible design, the flexible display includes a first part and a second part, and the first antenna unit is located in the first part. The second antenna unit is located in the second part, and the first part and the second part rotate relative to each other. Based on this scheme, an example of the correspondence between a flexible display and an antenna unit is provided. The first antenna unit involved in this example is located in the first part. In a specific implementation, the first antenna unit may be on the first part of the flexible display; in other implementations, the first antenna unit may also be in the projection area corresponding to the first part of the flexible display in the Z direction. The positional relationship between the second antenna unit and the second part is similar. It should be noted that this example only provides one possible positional relationship correspondence, that is, the two antenna units can be located on different folding screens. In other implementations, the two antenna units may also be located on the same folding screen.

[0016] In a third aspect, a wireless communication method is provided, and the method is applied to an electronic device, and the electronic device is provided with a wireless communication system as described in any one of the first aspect and its possible designs, and one or more processors. The method includes: the processor sends first control information to a first switching device, and the first control information is used to control the first switching device to operate in a first working state. In the first working state, the first switching device is configured to conduct the first antenna unit and the first radio frequency channel, and the first switching device is also configured to conduct the second antenna unit and the first radio frequency channel. The processor sends second control information to the first switching device, and the second control information is used to control the first switching device to operate in a second working state. In the first working state, the first switching device is configured to conduct the first antenna unit and the first radio frequency channel, and the second antenna unit and the first radio frequency channel are not conducting.

[0017] In a possible design, when the first switching device is in the first working state, the signals flowing through the first antenna unit and the second antenna unit are both the first signals. When the first switching device is in the second working state, the signal flowing through the first antenna unit is the second signal, and the second signal does not flow through the second antenna unit.

[0018] In a possible design, when the first switching device is in the first working state, the RF parameter of the first signal is the first parameter. When the first switching device is in the second working state, the RF parameter of the second signal is the second parameter, wherein the first parameter and the second parameter are different.

[0019] In one possible design, the RF parameters include reference signal received power RSRP and / or bit error rate.

[0020] In one possible design, the processor sends third control information to the first switching device, and the third control information is used to control the first switching device to operate in a third operating state. In the third operating state, the first switching device is configured to conduct the first antenna unit and the first radio frequency channel, and the first switching device is also configured to conduct the second antenna unit and the second radio frequency channel, and the signal flowing through the first antenna unit is the third signal, and the signal flowing through the second antenna unit is the fourth signal.

[0021] According to a fourth aspect, a processor is provided, which is arranged in an electronic device and is used to execute a wireless communication method as described in any one of the third aspect and its possible designs.

[0022] In a fifth aspect, an electronic device is provided, wherein the electronic device is provided with one or more processors as provided in the fourth aspect, a memory, and a wireless communication system as provided in the first aspect and possible designs thereof, wherein the one or more processors are coupled with the memory and the wireless communication system, and the memory stores computer instructions. When the one or more processors execute the computer instructions, the electronic device executes the wireless communication method as described in any one of the third aspect and possible designs thereof.

[0023] It should be understood that the technical solutions provided in the third, fourth and fifth aspects mentioned above and their technical features can all correspond to the technical solutions provided in the first aspect and its possible designs, so the beneficial effects that can be achieved are similar and will not be repeated here.

[0024] In a sixth aspect, an antenna system is provided, which is applied to an electronic device, and the antenna system includes: N switching devices, M antenna units, one switching device corresponds to at least two antenna units, and the at least two antenna units corresponding to one switching device constitute an antenna pair. N is a positive integer, and M is an integer greater than N. The output end of the first switching device is coupled to the first antenna pair, the first switching device is any one of the N switching devices, and the at least two antenna units included in the first antenna pair are included in the M antenna units. The first switching device has a first working state and a second working state. When the first switching device works in the first working state, the null point direction of the antenna system's directional pattern is a first direction. When the first switching device works in the second working state, the null point direction of the antenna system's directional pattern is a second direction, and the first direction is different from the second direction.

[0025] Based on this solution, an antenna system is provided that can solve the problem of communication obstruction caused by the zero point of the directional pattern. In this antenna system, N switching devices are innovatively proposed. By controlling the working state of the switching device, the directional pattern of the antenna unit in the working state (i.e., the directional pattern of the antenna system) can be flexibly adjusted according to the environment. For example, in the first working state, the directional pattern of the antenna system can present a different distribution from the directional pattern of the antenna system in the second working state, thereby making the position of the zero point of the directional pattern different in different working states. In this way, in one state, communication obstruction may occur when the zero point of the directional pattern is close to the signal direction, so the working state can be switched to another state, and the zero point of the directional pattern is offset by reconstructing the directional pattern, thereby avoiding the coincidence of the signal direction with the zero point of the directional pattern, and further avoiding the communication obstruction caused by the zero point of the directional pattern.

[0026] In one possible design, the frequency bands covered by at least two antenna units included in the first antenna pair partially overlap or completely overlap. Based on this solution, a possible setting example of an antenna pair is provided. For example, the two antenna units constituting the antenna pair may have partially overlapping working frequency bands. In this way, when transmitting and receiving signals in the working frequency band, it is possible to achieve reconstruction of the directional pattern by adjusting the number of antenna units in the working state in the antenna pair without affecting the transmission and reception of signals.

[0027] In a possible design, the first switching device operates in a first working state. When the reference signal received power RSRP is less than a first threshold. Or, when the bit error rate is greater than a second threshold. Or, when RSRP is less than the first threshold and the bit error rate is greater than the second threshold, the working state of the first switching device is switched from the first working state to the second working state. Based on this scheme, a possible correspondence between the working state and other parameters is provided. Based on this correspondence, the electronic device can flexibly select the corresponding working state according to the change of parameters (such as radio frequency parameters) to achieve the effect of flexibly reconstructing the directional pattern according to the communication environment.

[0028] In one possible design, when the first switching device operates in the first working state, the number of antenna units in the first antenna pair that receive and / or transmit signals is different from the number of antenna units in the first antenna pair that receive and / or transmit signals when the second switching device operates in the first working state. Based on this scheme, a possible mechanism for realizing pattern reconstruction is provided. For example, the pattern reconstruction can be realized by adjusting the number of antenna units in working state under different working states. It can be understood that the pattern of an antenna unit in only one working state is generally different from the pattern of other antenna units, and is also different from the pattern synthesized when two antenna units operate simultaneously. Therefore, the pattern reconstruction can be realized by reconstructing the number of antenna units in working state.

[0029] In a possible design, when the throughput of the electronic device is less than the third threshold, the first switching device operates in the first working state. Based on this solution, an example of a mechanism for determining the working state is provided. In this example, the electronic device can control the first switching device to operate in the first working state when it is determined that a higher throughput is not required. Of course, in other implementations, the electronic device can also control the first switching device to operate in the second working state when a higher throughput is not required.

[0030] In a possible design, the first switching device also has a third working state. When the first switching device operates in the third working state, the number of antenna units in the first antenna pair that receive and / or send signals is greater than the number of antenna units in the first antenna pair that receive and / or send signals when the first switching device is in the first working state or in the second working state. When the throughput of the electronic device is greater than a fourth threshold, the first switching device operates in a third working state, wherein the fourth threshold is greater than or equal to the third threshold. Based on this scheme, another example of a scheme for improving throughput in a flexible and convenient manner is provided. In this example, two antenna units can be controlled to operate simultaneously to receive and send signals, such as transmitting the received signals to the front end through different radio frequency channels to achieve a multi-stream effect, thereby improving throughput.

[0031] In a possible design, the antenna system also includes a second switching device and a second antenna pair. The output end of the second switching device is coupled to the second antenna pair, the second switching device is any one of the N switching devices, and the at least two antenna units included in the second antenna pair are included in the M antenna units. The second switching device has at least a first working state and a second working state. When the first switching device works in the first working state, the null point direction of the directional diagram of the antenna system is a first direction. When the first switching device works in the second working state, the null point direction of the directional diagram of the antenna system is a second direction, and the first direction is different from the second direction. Based on this scheme, a mechanism including more switching devices and corresponding antenna pairs is provided. It can be understood that in the antenna system of the electronic device, more first switching devices and corresponding antenna pairs mentioned in the above examples can be provided, and similar operations can be performed, thereby providing a more flexible communication quality improvement scheme for the electronic device.

[0032] In a seventh aspect, a wireless communication system is provided, the wireless communication system comprising the antenna system according to any one of the sixth aspect and its possible designs, and a radio frequency module, wherein the radio frequency module is coupled to the input ends of N switching devices respectively. The radio frequency module is used to transmit a transmission signal to an antenna pair corresponding to one or more switching devices through one or more switching devices among the N switching devices, so as to send a transmission signal through the antenna. Alternatively, a reception signal from an antenna pair corresponding to one or more switching devices is received and processed through one or more switching devices among the N switching devices.

[0033] In a possible design, the RF module includes a first RF channel, the first antenna pair includes a first antenna unit and a second antenna unit, and the working frequency band of the first antenna unit and the working frequency band of the second antenna unit partially overlap or completely overlap. When the first switching device operates in the first working state, the first RF channel is coupled to the first antenna unit, and when transmitting a transmit signal, the first RF channel sends the transmit signal through the first antenna unit. When receiving a receive signal, the first RF channel receives a receive signal received from the first antenna unit. When the first switching device operates in the second working state, the first RF channel is coupled to the first antenna unit and the second antenna unit, and when transmitting a transmit signal, the first RF channel sends the transmit signal through the first antenna unit and the second antenna unit. When receiving a receive signal, the first RF channel receives a receive signal received from the first antenna unit and the second antenna unit.

[0034] In one possible design, the RF module includes a first RF channel, the first antenna pair includes a first antenna unit and a second antenna unit, and the operating frequency band of the first antenna unit and the operating frequency band of the second antenna unit partially overlap or completely overlap. When the first switching device operates in a third working state, the first RF channel is coupled to the first antenna unit, and the second RF channel is coupled to the second antenna unit. When transmitting a transmit signal, the first RF channel sends the corresponding first transmit signal through the first antenna unit, and the second RF channel sends the corresponding second transmit signal through the second antenna unit. When receiving a receive signal, the first RF channel receives a signal received from the first antenna unit, and the second RF channel receives a signal received from the second antenna unit.

Or, when the bit error rate is greater than a second threshold. Or, when the RSRP is less than the first threshold and the bit error rate is greater than the second threshold.

[0036] In one possible design, before the processor sends the first control information to the first switching device, the method also includes: the processor determines that the throughput rate of the electronic device is less than a third threshold.

[0037] In one possible design, when the processor determines that the throughput rate of the electronic device is greater than a fourth threshold, the processor sends third control information to the first switching device to control the first switching device to operate in a third operating state.

[0065] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0066] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

[0067] One or more antenna units may be provided in the electronic device, and each antenna unit is coupled to a corresponding radio frequency module to realize the transmission and reception of signals. Exemplarily, during the reception process, the electronic device may convert electromagnetic waves in space into current signals with different characteristics through an antenna, and the electronic device may obtain the information carried by the electromagnetic waves by parsing the current signals through the radio frequency module. During the transmission process, the electronic device may also feed an electrical signal loaded with the information to be transmitted to the antenna through the radio frequency module, so that the antenna may convert the electrical signal into an electromagnetic wave of the corresponding frequency and transmit it, and then when other devices receive the electromagnetic wave, they may receive the electromagnetic wave through the antenna provided therein, thereby realizing the wireless transmission of information.

[0068] As an example, see Figure 2 , shows a schematic diagram of an antenna system. Figure 2 As shown, in the antenna system, multiple antenna units (such as Figure 2 The antenna unit 1, antenna unit 2, antenna unit 3 and antenna unit 4 are shown). The working frequency bands of any two antenna units can be the same or different. The set of working frequency bands of all four antenna units can cover the wireless communication frequency bands required by electronic devices. The antenna system can be used to transmit and receive signals. For example, take controlling antenna unit 1 to transmit signals as an example. The RF module can feed an electrical signal with a frequency band of f1 into antenna unit 1. Among them, the working frequency band of antenna unit 1 covers the frequency band f1. Antenna unit 1 can convert the fed electrical signal into an electromagnetic wave to propagate in space, thereby realizing the transmission of the electrical signal. Similarly, the RF module can control other antenna units (such as antenna unit 2, antenna unit 3 and antenna unit 4) to transmit signals. For another example, take controlling antenna unit 1 to receive signals as an example. Antenna unit 1 can receive electromagnetic waves corresponding to its working frequency band, and convert the electromagnetic waves into electrical signals with corresponding characteristics (such as corresponding amplitude and phase). The electrical signal can be transmitted to the RF module so that the RF module parses the electrical signal and obtains the information loaded in the electrical signal. The signal is thereby received. Similarly, other antenna units (such as antenna unit 2, antenna unit 3 and antenna unit 4) can also receive electromagnetic waves of corresponding frequency bands and convert them into electrical signals to be analyzed by the radio frequency module, thereby achieving corresponding signal reception.

[0069] In the fixed antenna radiation scheme, the reception / transmission of signals of different frequencies is completed by a fixed antenna. Figure 1, take the example that the working frequency bands of antenna unit 1 to antenna unit 4 are different (for example, the working frequency band of antenna unit 1 is band 1, the working frequency band of antenna unit 2 is band 2, the working frequency band of antenna unit 3 is band 3, and the working frequency band of antenna unit 4 is band 4). When the electronic device needs to transmit / receive in band 1 or a sub-band in band 1, antenna unit 1 can be controlled to work. Similarly, when the electronic device needs to transmit / receive in band 2 or a sub-band in band 2, antenna unit 2 can be controlled to work. When the electronic device needs to transmit / receive in band 3 or a sub-band in band 3, antenna unit 3 can be controlled to work. When the electronic device needs to transmit / receive in band 4 or a sub-band in band 4, antenna unit 4 can be controlled to work.

[0070] In the above scheme, since the current distribution on the antenna unit is basically unchanged when it is working, the zero point of the antenna pattern is relatively fixed. Different antennas have zero points in the pattern, so the influence of the zero point in the pattern during communication cannot be eliminated.

[0071] In order to solve the above problems, the following two solutions can be used to reduce the impact of the directional pattern zero point on wireless communication.

[0072] Solution 1: Multi-antenna-selection (MAS) solution. In this solution, a switching device may be provided between the RF module and the antenna. Figure 3 . Take the case where the RF module is connected to antenna unit 1 and antenna unit 2 through a switching device. By default, the switching device can connect the RF module to antenna unit 1 and disconnect the RF module from antenna unit 2. That is, by default, the electronic device uses antenna unit 1 for transmission / reception. The electronic device can control the RF module to monitor relevant parameters in the transmission / reception process through antenna unit 1. When the relevant parameter is lower than the preset threshold, it indicates that the current transmission / reception effect using antenna unit 1 is poor. At this time, the electronic device can control the switching device to disconnect the RF module from antenna unit 1 and connect it to antenna unit 2. Then switch to transmitting / receiving signals through antenna unit 2. Since the zero point directions of the directional patterns of antenna unit 1 and antenna unit 2 are generally different, the problem of poor communication quality caused by the zero point of the directional pattern of antenna unit 1 can be appropriately avoided by switching the antenna units.

[0073] However, since antenna unit 2 also has a pattern zero point, there is also a hidden danger that the pattern zero point will affect the communication quality. In addition, since the pattern zero points of antenna unit 1 and antenna unit 2 are not different in all cases, and with the development of electronic equipment, the antenna space is getting worse, which also makes the area with low gain near the pattern zero point of a single antenna unit larger. For example, in a mobile phone with a folding screen, due to factors such as the increase in screen-to-body ratio and the reduction in mobile phone thickness, the space available for setting antennas is getting smaller and smaller, which will seriously affect the radiation performance of a single antenna. It is understandable that similar problems will also occur in the quality of the communication process carried out in this low-gain area. Therefore, the above-mentioned MAS solution can only circumvent the problem of poor communication quality caused by the pattern zero point within a limited range, but cannot solve the problem well.

[0074] Solution 2: Distributed antenna solution. It is understandable that in a transmitting scenario, when the same RF signal is simultaneously input to two antenna units for transmission, the two antenna units can constitute a distributed antenna. Similarly, in a receiving scenario, when the two antenna units simultaneously transmit the received signal to the RF module, the two antenna units can constitute a distributed antenna. Exemplarily, a group of distributed antennas may include a feeding network and two or more antenna units, wherein the multiple antenna units may be located at different locations of the electronic device. Combined with Figure 4 , take a feeding network connecting two antenna units (such as antenna unit 1 and antenna unit 2) as an example. When transmitting a signal, the RF module (not shown in the figure) can feed the RF signal into the distributed antenna. The feeding network in the distributed antenna can match and process the RF signal and transmit the corresponding signals to the two antenna units respectively. For example, signal 1 is transmitted to antenna unit 1, and signal 2 is transmitted to antenna unit 2. Among them, signal 1 controls antenna unit 1 to radiate, and signal 2 controls antenna unit 2 to radiate. By working with two antenna units at the same time, one of the two antenna units can compensate for the radiation of the zero point of the directional pattern of the other antenna unit, thereby achieving the purpose of improving the overall radiation effect.

[0075] It is understandable that in a distributed antenna design, the more antenna units there are, the better the overall radiation effect. However, the more antenna units there are, the more space the antenna will occupy in the electronic device. However, since the space available for arranging antenna units in current electronic devices (especially portable electronic devices) is very limited, distributed design is becoming increasingly difficult to implement. For example, in a mobile phone with a folding screen, due to limited space, the antenna may need to be set near different screens, which also increases the difficulty of implementing a distributed antenna solution.

[0076] It can be seen that the above two solutions (such as the MAS solution and the distributed antenna solution) can solve the problem of poor communication quality caused by the zero point of the antenna inherent pattern within a certain range. However, due to the limitations of antenna space, cost and other factors, the above solutions cannot significantly improve the communication quality.

[0077] It should be noted that the improvement of communication quality can also be achieved by increasing the throughput (that is, increasing the number of received signal streams). For example, the more antenna units that work independently at the same time, the more each antenna unit can provide signals to the RF module through its corresponding RF link (RF chain) during the reception process. This enables the RF module to receive more valid signals, thereby achieving the purpose of improving throughput. Combined with the above solution description, through the MAS solution, since its essence is the switching of a single antenna, that is, the number of antennas working at the same time will not change, it is of no help in improving throughput. When using the above-mentioned distributed antenna solution, multiple antennas (such as Figure 4 When antenna unit 1 and antenna unit 2 in the figure form a distributed antenna, their front ends correspond to the same RF link, so it is equivalent to combining antenna unit 1 and antenna unit 2 into one antenna, so the throughput cannot be improved.

[0078] Based on the above description, the current antenna design in electronic devices cannot effectively avoid the zero point of the antenna pattern, and can only provide limited throughput, so it cannot provide good wireless communication quality. It should be noted that these problems are more significant when space requirements are high (such as in electronic devices with folding screens).

[0079] In order to solve the above problems, an embodiment of the present application provides an antenna switching method. The electronic device can adaptively reconstruct the number and / or directional pattern of the antenna unit, so that when the communication environment is poor, the electronic device can radiate through a larger antenna aperture, thereby significantly avoiding the influence of the directional pattern zero point of the fixed antenna on the communication quality. When the communication environment is good, the electronic device can radiate through more antenna units, thereby improving the throughput.

[0080] It should be noted that the solution provided in the embodiments of the present application can be applied to different electronic devices. For example, the electronic device can be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA) and other mobile terminals. The embodiments of the present application do not impose any restrictions on the specific types of electronic devices. In some implementations, the solution provided in the embodiments of the present application can be applied to electronic devices with folding screens, and can significantly improve the communication quality.

[0081] The solution provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0082] Please refer to Figure 5 , is a schematic diagram of the composition of a communication system (or wireless communication system) provided in an embodiment of the present application. The communication system can be set in an electronic device to implement the communication function of the electronic device. Figure 1 As shown, the communication system may include a processor 100, a filter 200, a low noise amplifier (LNA) 300, a power amplifier (PA) 400, a switch 500, and an antenna module 600. In some implementations, the antenna module 600 may include one or more antennas (ANT) 601.

[0083] The processor 100 may include one or more processing units, for example, the processor 100 may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a neural-network processing unit (NPU), a controller, a video codec, a digital signal processor (DSP), a baseband, and / or a radio frequency integrated circuit, etc. The controller may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions.

[0084] A memory may be provided in the processor 100 for storing instructions and data. In some embodiments, the memory in the processor 100 includes a cache memory. The memory may store instructions or data that the processor 100 has just used or cyclically used. If the processor 100 needs to use the instruction or data again, it may be directly called from the memory. Repeated access is avoided, the waiting time of the processor 100 is reduced, and the efficiency of the system is improved. In some embodiments, the memory may also be provided outside the processor and coupled to the processor 100.

[0085] like Figure 5 As shown, in this example, the processor 100 may include a baseband (BB) processor 101 and a radio frequency integrated circuit (RFIC) 102. In this example, the baseband processor may be referred to as a baseband.

[0086] Exemplarily, the baseband 101 can be used to synthesize the baseband signal to be transmitted, or / and to decode the received baseband signal. Specifically, when transmitting, the baseband can encode the voice or other data signal into the baseband signal (baseband code) for transmission; when receiving, the baseband can decode the received baseband signal (baseband code) into voice or other data signals. In some implementations, the baseband 101 may include components such as an encoder, a decoder, and a baseband controller. The encoder is used to synthesize the baseband signal to be transmitted, and the decoder is used to decode the received baseband signal. The baseband controller can be a microprocessor (Microprocessor or Micro Central Processing Unit, MCU), and the baseband controller can be used to control the encoder and decoder. For example, the baseband controller can be used to complete the scheduling of encoding and decoding, the communication between the encoder and the decoder, and the peripheral driver (can send an enable signal to the components outside the baseband to enable the components outside the baseband), etc.

[0087] The radio frequency integrated circuit (RFIC) 102 is used to process the baseband signal to form a transmit (Transmit, TX) signal, and pass the transmit signal to the power amplifier 400 for amplification; or / and, the radio frequency integrated circuit is used to process the receive (Receive, RX) signal to form a baseband signal, and send the formed baseband signal to the baseband 101 for decoding. It can be understood that the baseband processor 101 can process digital signals such as baseband signals, while the radio frequency integrated circuit 102 can be used to process analog signals such as radio frequency signals. A digital-to-analog / analog-to-digital conversion component can be provided between the baseband processor 101 and the radio frequency integrated circuit 102 for digital-to-analog conversion / analog-to-digital conversion when data is transmitted between the baseband processor 101 and the radio frequency integrated circuit 102. Of course, in other implementations, the digital-to-analog / analog-to-digital conversion component can also be integrated in the baseband processor 101 or the radio frequency integrated circuit 102.

[0088] The processor 100 may modulate the signal according to a mobile communication technology or a wireless communication technology. The mobile communication technology may include global system for mobile communications (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division code division multiple access (TD-SCDMA), long term evolution (LTE), emerging wireless communication technology (also known as the fifth generation mobile communication technology, English: 5th generation mobile networks or 5th generation wireless systems, 5th-Generation, 5th-Generation New Radio, referred to as 5G, 5G technology or 5G NR), etc. Wireless communication technologies may include wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), nearfield communication (NFC), infrared technology (IR), etc.

[0089] The processor 100 may include at least one baseband 101 and at least one radio frequency integrated circuit 102. In some embodiments, each baseband 101 corresponds to an radio frequency integrated circuit 102 to frequency modulate the signal according to one or more communication technologies. For example, the first baseband and the first radio frequency integrated circuit frequency modulate the signal according to 5G technology, the second baseband and the second radio frequency integrated circuit frequency modulate the signal according to 4G technology, the third baseband and the third radio frequency integrated circuit frequency modulate the signal according to Wi-Fi technology, the fourth baseband and the fourth radio frequency integrated circuit frequency modulate the signal according to Bluetooth technology, and so on. Alternatively, the first baseband and the first radio frequency integrated circuit can frequency modulate the signal according to 4G technology and 5G technology at the same time, the second baseband and the second radio frequency integrated circuit frequency modulate the signal according to Wi-Fi technology, and so on. In some embodiments, one baseband 101 can also correspond to multiple radio frequency integrated circuits 102 to improve the integration.

[0090] In some embodiments, the baseband 101 and the RFIC 102 may be integrated with other components of the processor 100 in one integrated circuit. In some embodiments, the baseband 101 and the RFIC 102 may be independent devices of the processor 100. In some embodiments, a baseband 101 and a RFIC 102 may be integrated into a device independent of the processor 100. In some embodiments, the baseband 101 and the RFIC 102 are integrated into different integrated circuits, and the baseband 101 and the RFIC 102 are packaged together, for example, in a system on a chip (SOC).

[0091] In the processor 100 , different processing units may be independent devices or may be integrated into one or more integrated circuits.

[0092] The antenna module 600 is used to transmit radio frequency signals. The antenna module 600 can also be used to receive electromagnetic wave signals and convert electromagnetic wave signals into radio frequency signals. The antenna module 600 may include multiple antennas 601 or multiple groups of antennas (multiple groups of antennas include more than two antennas), and each antenna 601 or multiple groups of antennas can be used to cover a single or multiple communication frequency bands. Any of the multiple antennas can be a single-frequency or multi-frequency antenna. In some implementations, the multiple antennas may include an array antenna composed of multiple antenna elements. In a specific implementation, the radiator of any of the multiple antennas may include, but is not limited to, a metal frame of an electronic device, and / or a metal back shell, and / or a metal component of other devices (such as a camera, etc.) and other structures with conductive properties. The radiator of any of the multiple antennas may also include a flexible printed circuit (Flexible Printed Circuit, FPC) antenna, and / or a stamping (stamping) antenna, and / or a laser etching (Laser-Direct-structuring, LDS) antenna and other forms of components. In some implementations, any of the multiple antennas may also be an on-chip antenna.

[0093] like Figure 5 As shown, the antenna module 600 may also include an antenna circuit 602. The antenna circuit 602 may also be referred to as a matching circuit. The matching circuit may include one or more capacitors, and / or inductors, and / or resistors. The matching circuit may also include adjustable components, such as adjustable inductors, and / or adjustable capacitors. The matching circuit may be used to adjust the impedance of the antenna 601. By tuning the matching circuit, the impedance of the antenna 601 may be as close as possible to the impedance of the RF signal (e.g., 50 ohms, or 75 ohms) within the operating frequency band. This reduces the loss or reflection at the antenna port when the RF signal is transmitted to the antenna 601, thereby improving the radiation efficiency of the communication system.

[0094] In the embodiment of the present application, the processor 100 is coupled with the antenna circuit 600 to implement various functions associated with transmitting and receiving radio frequency signals. For example, when the electronic device transmits a signal, the baseband 101 can load the data to be transmitted on the digital signal by digital modulation, thereby obtaining a baseband signal corresponding to the data to be transmitted. The baseband signal is converted into a transmission signal (radio frequency signal) by the radio frequency integrated circuit 102, and the transmission signal is amplified by the power amplifier 400. The amplified output signal output by the power amplifier 400 is transmitted to the switch 500 and transmitted through the antenna circuit 600. The path for the transmission signal to be sent from the processor 100 to the switch 500 is the transmission link (or transmission path). When the electronic device needs to receive a signal, the antenna circuit 600 sends the received signal (radio frequency signal) to the switch 500, and the switch 500 sends the radio frequency signal to the radio frequency integrated circuit 102. The radio frequency integrated circuit 102 processes the radio frequency signal into a baseband signal and sends it to the baseband 101. The baseband 101 converts the processed baseband signal into data and sends it to the corresponding application processor. The path for the RF signal to be sent from the switch 500 to the processor 100 is the receiving link (or receiving path). The port in the processor 100 connected to the transmitting link is the transmitting port TX, and the port in the processor 100 connected to the receiving link is the receiving port RX.

[0095] The switch 500 may be configured to selectively electrically connect the antenna circuit 600 to a transmit link or a receive link. In some embodiments, the switch 500 may include a plurality of switches. The switch 500 may also be configured to provide additional functions, including filtering and / or duplexing signals. Figure 5 As shown, in some implementations of the embodiments of the present application, a filter 200 and a PA 300 may be provided on the TX link corresponding to the switch 500, and a filter 200 and an LNA 400 may be provided on the RX link corresponding to the switch 500. It is understood that the filter 200, the PA 300 and the LNA 400 may be used to process the RF signal on the corresponding link to achieve the effect of improving the signal quality. It should be noted that, as Figure 5 The composition shown is only an example. In other implementations of the present application, different TX links and / or RX links may be provided in the communication system for different operating frequency bands. The composition of the components included in each TX link is also not limited to Figure 5 For example, some TX links may not be provided with PA 300. When the signal of the link needs to be amplified, the signal on the link can be introduced into the PA 300 on other TX links through the RF line to achieve time / frequency sharing of PA 300. Similarly, the components included in each RX link are not limited to Figure 5 For example, the RX link corresponding to the frequency band (such as the roaming frequency band) with low signal quality requirements may not include the LNA 400, thereby achieving the effect of reducing the hardware cost while meeting the signal quality requirements.

[0096] For ease of explanation, the following example takes the RX link including the filter 200 and the LNA 400, and the TX link including the filter 200 and the PA 300. In the embodiment of the present application, the components in the RX link included in the communication system, and the collection of components in the TX link, can be referred to as a radio frequency module. It can be understood that when a plurality of RX links and / or TX links are included in the radio frequency module, an RX link or a TX link can also be referred to as a radio frequency channel. It should be noted that in some implementation scenarios, when the RX link and the TX link are the same physical link, the physical link can also correspond to a radio frequency channel.

[0097] In other embodiments of the present application, the communication system of the electronic device may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0098] In order to more clearly illustrate the composition of the communication system provided in the embodiment of the present application, the following Figure 6 right Figure 5 The antenna module 600 is shown for exemplary purposes. Figure 6 , shows a schematic diagram of the composition of an antenna module 600 (or antenna system). Figure 6As shown, the antenna system can be electrically connected to the RF module. In the antenna system, 2*N antennas coupled to the RF module can be provided, where N is an integer greater than or equal to 2. In these 2N antennas, two antennas with the same coverage frequency band can constitute an antenna pair. For example, take the example that antenna unit A3 and antenna unit A4 have the same coverage frequency band. The first antenna path including antenna unit A3 and feeding device A1 can form a first antenna pair with the second antenna path including antenna unit A4 and feeding device A2. Similarly, other antenna paths can also form antenna pairs in pairs. Among them, the feeding device can be an RF transmission line (such as an RF transmission line with impedance controlled at 50 ohms), a metal pin, a metal shrapnel, etc., which is used for transmission between electrical signals on the antenna path and the antenna radiator. In some implementations of the present application, the feeding device may also include a phase shifter for adjusting the phase of the signal at the antenna port so as to control the phase of the antenna radiation. For example, by adjusting the phase shifters corresponding to the two antenna units working simultaneously, the radiation phases of the two antenna units differ by 90 degrees, thereby achieving a dual-polarization radiation effect, thereby reducing the mutual influence of the two antenna units when working simultaneously, and improving the system signal quality. It should be noted that other components may also be included in the antenna path. For example, a matching circuit corresponding to the antenna set on the antenna path and / or other RF devices for realizing the antenna radiation function may be included. Among them, the matching circuit can adjust the impedance between the antenna unit and the RF module, and the matching circuit may include one or more of a capacitor, an inductor and a switch. In different states, the matching circuit can adjust its own capacitance value, inductance value and one or more of the switch state, so that the impedance between the antenna unit and the RF module is matched. In some embodiments, the antenna path may also not include a feeding device.

[0099] It should be noted that Figure 6 The antenna system in is only an example of a possible composition. For example, in the antenna system, the antenna part coupled to the switching device 1 may include a feeding device A1, an antenna unit A3 and a feeding device A2, an antenna unit A4. Similarly, the antenna part coupled to the switching device 2 may include 2 feeding devices and 2 antenna units. That is, in this example, the N switching devices included in the antenna system can be set separately. In other implementations of the present application, these N switching devices (such as switching devices 1-switching devices N) may also be partially or fully integrated in one component. Combined with Figure 5 In other implementations, one or more of the N switching devices (such as switching device 1-switching device N) included in the antenna system may also be integrated with the switching switch 500 and set in an electronic device.

[0100] In addition, combined with the above description of the RF module, Figure 6 The RF module shown can be used to process RF signals. For example, the RF module may include at least one of a filter, a combiner, a power amplifier, or a linear amplifier. Specifically, each RF channel may include a component for processing a RF signal, for example, each RF channel may include at least one of a filter, a combiner, a power amplifier, or a linear amplifier.

[0101] In this example, one antenna pair may also correspond to one switching device, and the switching device may be arranged between the antenna path included in the antenna pair and the radio frequency module. The electronic device may control the switching device so that the antenna pair operates in different states. In different implementations of the present application, the switching device may realize the change of its switching state based on different control modes. In some implementations, for a switching device controlled by a general-purpose input / output interface (GPIO), the processor or baseband in the electronic device may adjust the state of the analog control signal on the GPIO control line so that the switching device operates in different working states. For example, take the switching device being controlled by two GPIO control lines as an example. The processor or baseband may control the analog control signal on the GPIO control line to operate at a high level or a low level, where the high level corresponds to 1 and the low level corresponds to 0, then the processor or baseband may control the switching device to operate in at least 4 working states of 01, 10, 00, and 11. In other implementations, for a switching device controlled by a mobile industry processor interface (MIPI), a processor or baseband in an electronic device can control the state of a corresponding bit of a digital control signal transmitted on a MIPI signal line (such as setting it to 0 or 1) to enable the switching device to operate in different operating states.

[0102] It should be noted that the control instructions of the switching device involved in the above example may be stored in the internal storage area of ​​the processor or baseband, and retrieved and sent to the switching device when the working state of the switching device needs to be adjusted. In some other implementations of the present application, the above control instructions may also be stored in other components of the electronic device with storage functions. For example, the control instructions may be stored in the internal memory of the electronic device, or in the external memory of the electronic device. The embodiments of the present application do not limit the storage location of the control instructions.

[0103] Exemplary, combined Figure 7 ,by Figure 6Taking the first antenna pair in the antenna system as an example, the electronic device control switching device adjusting the working state of the antenna pair is described. In the following embodiments, the first RF channel is RF channel RF2 and the second RF channel is RF channel RF1 as an example.

[0104] like Figure 7 As shown, a plurality of RF channels may be included in the RF module, and one RF channel may be used to support at least one antenna path to realize signal reception or transmission of a frequency band. For example, the first antenna path may selectively correspond to the RF channel RF1, and the second antenna path may selectively correspond to the RF channel RF2. In this example, when the first antenna path corresponds to the RF channel RF1, and the second antenna path corresponds to the RF channel RF2, during the transmission process, when the RF channel RF1 is connected to the first antenna path, the RF channel RF1 may transmit the electrical signal to the antenna unit A3 through the feeding device A1 for radiation of the frequency band 1. During the reception process, the signal of the frequency band 1 received by the antenna unit 3 may be transmitted to the RF channel RF1 through the feeding device A1, so that the RF channel RF1 may parse the signal and realize signal reception. Similarly, during the transmission process, when the RF channel RF2 is connected to the second antenna path, the RF channel RF2 may transmit the electrical signal to the antenna unit A4 through the feeding device A2 for radiation of the frequency band 1. During the receiving process, the signal of the frequency band 1 received by the antenna unit A4 can be transmitted to the radio frequency channel RF2 through the feeding device A2, so that the radio frequency channel RF2 can analyze the signal and realize the reception of the signal.

[0105] exist Figure 7 In the example, a switching device 1 includes three single-pole single-throw switches (SPST), such as switch 1, switch 2 and switch 3. One end of switch 1 is coupled to the RF channel RF1, and the other end of switch 1 is coupled to the feeding device A1. One end of switch 2 is coupled to the RF channel RF2, and the other end of switch 2 is coupled to the feeding device A2. One end of switch 3 is coupled to the RF channel RF2, and the other end of switch 3 is coupled to the feeding device A1. It should be noted that in the description of this example, the switching device is taken as an example in which three SPSTs are used to realize its switching function. In other implementations, the switching device can also realize its switching function through other components. For example, the switching device can include 1 SPST and 1 2SPST to realize its switching function.

[0106] In this example, the electronic device can control the first antenna pair to work in different working states by controlling the switching device 1 including the three SPSTs. The working mechanism of each working state of the first antenna pair in the transmission scenario is illustrated below.

[0107] Status 1: Please refer to Figure 8 (a) in the figure. The electronic device can control the switch 1 in the switching device 1 to be disconnected, and the switches 2 and 3 to be turned on. In this state, the RF module can radiate the electrical signal through the antenna unit A3 and the antenna unit A4 simultaneously through the RF channel RF2. At this time, the antenna unit A3 and the antenna unit A4 are combined into one antenna to radiate outward. In this state 1, the transmission signal (such as the transmission signal 1) is routed to the second antenna path through the RF channel RF2 and the switch 2, and at the same time, the transmission signal 1 is routed to the first antenna path through the RF channel RF2 and the switch 3. Thereby, the effect of radiating a single-channel transmission signal (i.e., the transmission signal 1) through two antenna units (antenna unit A3 and antenna unit A4) is achieved. Since the antenna unit A3 and the antenna unit A4 work at the same time, the directional patterns of the two antenna units are superimposed in space to form the corresponding directional pattern in the current working state (such as state 1). The directional pattern zero point of the directional pattern is different from that of the antenna unit A3 or the antenna unit A4, so the problem of decreased communication quality introduced by the directional pattern zero point of the antenna unit A3 or the antenna unit A4 can be avoided.

[0108] Status 2: Please refer to Figure 8 (b) in the figure. The electronic device can control the switches 1 and 2 in the switching device 1 to be turned on and the switch 3 to be turned off. In this state, the RF module can transmit the transmission signal to the antenna unit A3 for radiation through the RF channel RF1. At the same time, the RF module can also transmit the transmission signal to the antenna unit A4 for radiation through the RF channel RF2. In this state 2, the transmission signal (transmission signal 2) from the RF channel RF1 can be transmitted to the first antenna path through the switch 1 and radiated through the antenna unit A3. Similarly, the transmission signal (transmission signal 3) from the RF channel RF2 can be transmitted to the second antenna path through the switch 2 and radiated through the antenna unit A4. In this state, the RF signals (such as transmission signal 2 and transmission signal 3) transmitted to the antenna system by the RF channel RF1 and the RF channel RF2 can be the same. That is to say, in the transmission scenario, the RF module can use two antenna paths at the same time to transmit the corresponding signal, thereby significantly improving the system throughput compared to the state where only one antenna path is used for transmission.

[0109] In some embodiments, transmit signal 2 and transmit signal 3 may be two different transmit signals in a MIMO scenario; or, in some embodiments, transmit signal 2 and transmit signal 3 may be two different transmit signals in a dual connection scenario; or, in other embodiments, transmit signal 2 and transmit signal 3 may be signals of different frequency bands transmitted simultaneously in a carrier aggregation (CA) scenario, and so on.

[0110] It can be understood that in the transmission scenario, the transmission signal is transmitted from the RF module to the corresponding antenna path in the antenna system for radiation. In the receiving scenario, the antenna unit on the antenna path receives the electromagnetic wave (received signal) of the corresponding frequency band in the space, and converts the electromagnetic wave into an analog signal and transmits it to the RF module for analysis. It can be seen that the signal flow direction in the two processes of transmission and reception is opposite, so when the switching device is in different working states, the effect that can be achieved is also corresponding. Take the receiving scenario as an example, for example, in the above state 1, since the two antenna units (such as antenna unit A3 and antenna unit A4) work at the same time, the electromagnetic wave of the working frequency band is received, and the electromagnetic wave is converted into an analog signal and transmitted to the RF channel RF2 for analysis. Therefore, compared with the state in which only one antenna unit is working, the antenna system can collect electromagnetic waves in more directions, so that the RF module can obtain a more complete signal for analysis, thereby achieving the effect of improving the accuracy of signal analysis. For example, in the above state 2, since the antenna unit A3 and the antenna unit A4 work at the same time, the electromagnetic wave of the working frequency band is received, and the electromagnetic wave is converted into an analog signal and transmitted to the RF channel RF1 and the RF channel RF2 for analysis. Therefore, the RF module can receive two signals at the same time for analysis, thereby improving the system throughput and improving the analysis accuracy by comparing the analog parameters of the two signals. For ease of explanation, in the following embodiments, the implementation process of the present application scheme is described by taking the transmission scenario as an example, and the beneficial effects in the receiving scenario correspond to them and will not be repeated.

[0111] In an embodiment of the present application, the electronic device can flexibly adjust the working state of the antenna according to preset conditions and different communication requirements in the current environment, so that the antenna system can adaptively provide corresponding high-quality communication services in the current environment with the corresponding working state.

[0112] It is understandable that Figure 7 According to the logical connection shown, the electronic device can also control the first antenna pair to be in other working states:

[0113] Status 3: Please refer to Fig. 9 (a) in the figure. The electronic device can control the switch 1 and the switch 3 in the switching device 1 to be disconnected and the switch 2 to be turned on. At this time, the second antenna path works alone. The RF module can radiate the electrical signal through the antenna unit A4 through the RF channel RF2.

[0114] Status 4: Please refer to Fig. 9 (b) in the figure. The electronic device can control the switch 1 and the switch 2 in the switching device 1 to be disconnected and the switch 3 to be turned on. At this time, the first antenna path works alone. The RF module can radiate the electrical signal through the antenna unit A3 through the RF channel RF1.

[0115] When the electronic device uses antenna unit A4 to radiate (i.e., the first antenna pair is working in state 3), based on the current communication quality, it can know whether the current radiation is near the zero point of the directional diagram of antenna unit A4. If so, the electronic device can control antenna unit A3 in the first antenna pair to radiate (i.e., switch the working state to state 4), thereby avoiding the problem of decreased communication quality due to the zero point of the directional diagram of antenna unit A3. Similarly, when the incoming wave direction is close to the zero point of the directional diagram of antenna unit A4, the electronic device can switch the working state of the first antenna pair from state 4 to other states, such as state 3 or state 1, thereby changing the directional diagram of the first antenna pair in the current working state and avoiding the problem of decreased communication quality due to the zero point of the directional diagram.

[0116] The antenna unit A3 and the antenna unit A4 may be located at different positions of the electronic device. In the above description, the first antenna pair is described in detail. It is easy to understand that for example Figure 6 For other antenna pairs shown, the electronic device can control each antenna pair to work in different working states through similar methods, thereby avoiding the influence of the fixed antenna pattern zero point on the communication quality. At the same time, the throughput rate can be improved by adjusting the working state of the antenna pair in the required scenario. In this way, the overall communication quality of the electronic device can be significantly improved.

[0117] Based on the above Figure 6-Figure 9 The present application also provides an antenna switching method that can be applied to electronic devices. Fig.10 , wherein the electronic device is a mobile phone as an example for explanation. The method may include:

[0118] S1001. The mobile phone determines whether a switching condition is met.

[0119] Exemplarily, after being turned on, the mobile phone can obtain the communication parameters in the current communication process in real time, so as to determine whether it is necessary to switch the antenna working state according to the communication parameters and the corresponding preset thresholds. For example, the communication parameters may include reference signal receiving power (RSRP), received signal strength indication (RSSI), etc. Take the communication parameters including RSRP as an example. The mobile phone can determine the relationship between the RSRP of the current communication and the preset RSRP corresponding threshold in real time. When the RSRP of the current communication is greater than the preset RSRP corresponding threshold, the mobile phone can determine that the current antenna working state can meet the communication requirements, so the switching condition is not met, and there is no need to switch the antenna working state. When the RSRP of the current communication is less than the preset RSRP corresponding threshold, the mobile phone can determine that the current antenna working state cannot provide better communication quality, so the switching condition is met and the antenna working state needs to be switched.

[0120] In some other implementations of this example, the communication parameter may also be a bit error rate. The mobile phone may determine whether the switching condition is met based on the size of the bit error rate in the current communication process and the size relationship with the preset bit error rate threshold. For example, when the bit error rate of the current communication is greater than the preset bit error rate threshold, it is considered that the switching condition is met. When the bit error rate of the current communication is less than the preset bit error rate threshold, it is considered that no switching is required. Of course, in some other implementations of the present application, the communication parameters may also include the bit error rate and RSRP at the same time, so that the mobile phone can comprehensively judge the current communication situation and make a more accurate judgment. For example, when the bit error rate is greater than the bit error rate threshold, and the RSRP is greater than the RSRP threshold, the mobile phone determines that the switching condition is met.

[0121] It should be noted that in the above example, the mobile phone monitors the communication parameters in real time as an example. In other implementations of the present application, the mobile phone can also monitor the communication parameters by sampling at preset time intervals. In this way, it is possible to timely determine whether the switching conditions are met while appropriately reducing the power consumption introduced by monitoring the communication parameters.

[0122] When the mobile phone determines that the switching condition is not met, S1001 can be repeatedly executed. When the mobile phone determines that the switching condition is met, the following S1002 can be executed.

[0123] S1002. The mobile phone switches the current working state to the target working state.

[0124] It is understandable that when a mobile phone leaves the factory, multiple sets of switch states may be pre-configured inside the mobile phone. For example, the multiple sets of switch states may include Figure 8 and / or Fig. 9 In this example, the mobile phone can determine the working state to be switched, that is, the target switching state, through a variety of schemes. Fig.10 , the S1002 may include S1002A and S1002B.

[0125] S1002A. The mobile phone determines the target working state.

[0126] S1002B. The mobile phone switches the current working state to the target working state.

[0127] For example, in some implementations, the mobile phone may directly switch the current working state to the preset first working state when determining that the switching condition is met. For example, if the current working state is Fig. 9 If the state of (a) in the figure is satisfied, then when the switching condition is determined to be met, the mobile phone can directly switch the current working state of the antenna system to the following state: Fig. 9 The state marked by (b) in the figure. Fig. 9 After the state shown in (b) in FIG. 1 is reached, the mobile phone can execute the above S1001 repeatedly. If the switching condition is still met, the mobile phone can switch the current state to the following state: Figure 8 Similarly, if the current working state is another state, the mobile phone can switch to a working state with a higher priority different from the current working state based on a preset priority in the pre-configured working state, thereby achieving the effect of switching the antenna working state.

[0128] In other implementations, when the mobile phone determines that the switching condition is met, it can control the antenna system to work in each preset switch state, and monitor the size of the communication parameter (such as RSRP) in different switch states (in this example, the method can also be called polling of the preset switch state). In this way, the mobile phone can obtain the working effect of each switch state in the current communication environment. In this example, the mobile phone can determine the working state of the antenna corresponding to the corresponding RSRP maximum switch state as the target working state. By looking up the table, the mobile phone can determine the control signal of the switch logic corresponding to the target working state, so that the mobile phone can switch the current working state to the target working state according to the control signal. It should be noted that through the above scheme, the mobile phone can determine the working state with the best working effect in the current communication environment as the target working state, and then control the antenna system to switch to the target working state. In other examples, the mobile phone can also control the antenna system to work in different preset switch states, obtain the corresponding RSRP, and when the RSRP is greater than the preset RSRP threshold, stop polling the preset switch state, and use the working state corresponding to the switch state where the current RSRP is greater than the preset RSRP threshold as the target working state. Then, by looking up the table, the mobile phone can determine the control signal of the switch logic corresponding to the target working state, so that the mobile phone can switch the current working state to the target working state according to the control signal.

[0129] It should be understood that, based on the above description of S1001-S1002, the acquisition and determination of communication parameters change with the change of the communication environment in which the mobile phone is located, that is, the determination and switching of the above working state are adaptively changed according to the change of the communication environment in which the mobile phone is located. This enables the mobile phone to switch the working state of the antenna to the optimal state with reference to the current communication environment in order to provide better communication quality. It is easy to understand that the switching of different working states causes the change of the antenna system directional pattern, thereby enabling the poor communication quality caused by the zero point of the directional pattern to be changed by switching the antenna working state and changing the antenna system directional pattern, thereby avoiding the influence of the zero point of the directional pattern on the communication quality.

[0130] It should be noted that in other implementations of the present application, the mobile phone can also flexibly adjust the working state of the antenna according to the throughput requirements in the current scenario. For example, before executing the above S1001, the mobile phone can execute the following Fig.10 S1003-S1004 shown.

[0131] S1003. The mobile phone determines whether it is a high throughput scenario.

[0132] The high throughput scenario may be preset in the mobile phone. For example, when the mobile phone determines that the current uplink or downlink throughput is greater than a preset throughput threshold, the current working scenario is determined to be a high throughput scenario. For another example, when the mobile phone determines that the current working scenario is in a video call scenario, the current working scenario is determined to be a high throughput scenario.

[0133] After determining that the current working scenario is a high throughput scenario, the mobile phone may execute the following S1004. If it is determined that the current working scenario is not a high throughput scenario, the mobile phone may execute the following Fig.10 S1001 shown.

[0134] In some embodiments, the high-throughput scenario may be a scenario with a relatively large throughput demand, or a scenario that requires low latency, such as video, live broadcast, autonomous driving, or mobile medical scenarios.

[0135] S1004. The mobile phone sets the current working state to a high throughput state.

[0136] When it is determined that there is a need to increase the throughput, the mobile phone can control the antenna to work in a corresponding high throughput state. Figure 8 , the mobile phone can set one or more antenna pairs in its antenna system as follows Figure 8 The working state shown in (b) in the figure achieves dual-channel transmission and reception, thereby achieving the purpose of improving throughput.

[0137] Through Fig.10 The scheme shown should be easy for those skilled in the art to understand the specific operation steps of the embodiments of the present application. Based on the above scheme, the electronic device can adaptively adjust the working state of the antenna according to the needs of the current communication environment to achieve the reconstruction effect of the number of antennas and / or antenna patterns, so as to achieve the purpose of improving communication quality.

[0138] In order to provide a more detailed description of the solution shown in the embodiment of the present application, the solution is exemplarily described below by taking an electronic device as an electronic device with a folding screen as an example.

[0139] The folding screen (also referred to as a folding device) provided in the electronic device can be folded to form at least two screens. For example, the folding screen can be folded to form a first screen and a second screen. It should be noted that the at least two screens formed after the folding screen is folded can be multiple independent screens, or a complete screen of an integrated structure, which is just folded to form at least two parts.

[0140] In the process of folding the folding screen, the parameters of the folding screen will change, such as the angle between the first screen and the second screen will change, and the folding speed, folding direction, folding acceleration, etc. of the folded screen will also change. The folded screen can be the screen of the first screen and the second screen that rotates when the user performs the folding operation.

[0141] To summarize, in the embodiments of the present application, changes in parameters such as the angle between the first screen and the second screen formed during the folding process of the folding screen, the folding speed of the folded screen, the folding acceleration and the folding direction can be matched with the settings of different working antennas in the electronic device, so that the electronic device can use different combinations of antennas to work in different forms, and realize the function of adaptively adjusting the working antenna according to the form of the electronic device, thereby achieving reconstruction of the number of antennas and / or antenna radiation patterns in different forms, thereby improving wireless communication performance.

[0142] For example, in some embodiments of the present application, the folding screen may be a flexible folding screen. The flexible folding screen includes a folding edge made of a flexible material. Part or all of the flexible folding screen is made of a flexible material. For example: only the foldable part (such as the folding edge) of the flexible folding screen is made of a flexible material, and the other parts are made of a rigid material; or, the flexible folding screen is made entirely of a flexible material. The folding screen can be folded along the folding edge to form multiple (two or more) screens.

[0143] For example, Fig.11 The folding screen shown in (a) is a flexible folding screen. Fig.11 The folding screen shown in (a) is a complete display screen, which includes a folding edge made of a flexible material. After the folding screen is folded along the folding edge, it can form Fig.11 Panel A 1101 and panel B 1102 as shown in (b) .

[0144] For example, Fig.12 The folding screen shown in (a) is also a flexible folding screen. Fig.12 The folding screen shown in (a) is a complete display screen, which includes a folding edge made of a flexible material. After the folding screen is folded along the folding edge, it can form Fig.12 The A screen 1201, the B screen 1202 and the C screen 1203 shown in (b) of FIG.

[0145] in, Fig.11 (a) and Fig.12 (a) in the figure is a schematic diagram of the folding screen when it is unfolded (or in other words, the folding screen is in the unfolded state). Fig.11 (b) and Fig.12 (b) in the figure is a schematic diagram of the folding screen in a semi-folded state. Fig.11 (c) in the figure is a schematic diagram of the folding screen in a closed state. It should be noted that in each embodiment of the present application, the folding screen has three states: an unfolded state, a closed state, and a semi-folded state. The unfolded state means that the folding screen is unfolded, that is, the angle between any two screens in the folding screen is 180°. The closed state means that the folding screen is completely folded, that is, the angle between any two screens in the folding screen is 0°. The state between the unfolded state and the closed state is a semi-folded state.

[0146] In some other embodiments of the present application, the folding screen may be a multi-screen folding screen. The multi-screen folding screen may include multiple (two or more) screens. It should be noted that these multiple screens are multiple separate display screens. These multiple screens can be connected in sequence through a folding axis. Each screen can rotate around the folding axis connected thereto to achieve the folding of the multi-screen folding screen.

[0147] In some implementations of the present application, the multi-screen folding screen includes two separate screens, for example, screen A and screen B. Screen A and screen B are connected by a folding axis, and screen A and screen B can rotate around the folding axis to achieve folding of the multi-screen folding screen. The multi-screen folding screen can also include three or more screens. Its specific form and folding method can be referred to Fig.13 And related descriptions will not be repeated here.

[0148] Among them, when the folding screen is in the closed state, the angle between adjacent screens is 0°. For example, Fig.11 The angle α between screen A and screen B shown in (c) is 0°. When the folding screen is in the unfolded state, the angle between adjacent screens is 180°. For example, Fig.11 The angle α between screen A and screen B shown in (a) is 180°. When the folding screen is in a semi-folded state, the angle between adjacent screens can range from (0° to 180°). For example, Fig.11 The included angle α∈(0°, 180°) between the A screen 1101 and the B screen 1102 shown in (b) is 0°.

[0149] Above Figure 11-Figure 12 In the embodiment, the folding screen of the electronic device is folded longitudinally to realize the folding of the folding screen. Of course, the folding screen of the electronic device can also be folded horizontally to realize the folding of the folding screen.

[0150] In addition, the above Figure 11-Figure 12 , which is a schematic diagram showing that the value range of the angle between adjacent screens of the folding screen is [0°, 180°]. Of course, the value range of the angle between adjacent screens of the folding screen may also include (180°, 360°). For example, Fig.11 Take the folding screen shown as an example. Fig.11The folding screen shown in (a) is folded along the folding edge to form screen A and screen B. It should be noted that in the embodiment of the present application, when the angle between any two screens in the folding screen is 360°, the folding screen can also be considered to be in a closed state.

[0151] Take a foldable device as a mobile phone with a foldable screen as an example. Multiple antennas can be respectively arranged on the shell corresponding to the A screen (such as called A shell) and the shell corresponding to the B screen (such as called B shell). Fig.13 As shown in (a), antenna unit 1, antenna unit 3, antenna unit 5, and antenna unit 7 may be provided on shell A. Antenna unit 2, antenna unit 4, antenna unit 6, and antenna unit 8 may be provided on shell B. In this example, the positions of antenna unit 1 and antenna unit 2 may be arranged relative to the folding edge. Similarly, the positions of antenna unit 3 and antenna unit 4 may be arranged relative to the folding edge. The positions of antenna unit 5 and antenna unit 6 may be arranged relative to the folding edge. The positions of antenna unit 7 and antenna unit 8 may be arranged relative to the folding edge. As shown in the figure, reference Fig.13 In (b), when the mobile phone is in a closed state, the projection areas of antenna unit 1 and antenna unit 2 on the display screen can be the same or similar. Similarly, the projection areas of antenna unit 3 and antenna unit 4 on the display screen can be the same or similar. The projection areas of antenna unit 5 and antenna unit 6 on the display screen can be the same or similar. The projection areas of antenna unit 7 and antenna unit 8 on the display screen can be the same or similar.

[0152] Among them, antenna unit 1 and antenna unit 2 can constitute an antenna pair, antenna unit 3 and antenna unit 4 can constitute an antenna pair, antenna unit 5 and antenna unit 6 can constitute an antenna pair, and antenna unit 7 and antenna unit 8 can constitute an antenna pair.

[0153] Combining the above Figure 6-Figure 10 In the description, the antenna switching method provided according to the embodiment of the present application is applied in the following Fig.13 In the mobile phone shown, the mobile phone can control each antenna pair in the antenna system including antenna unit 1 to antenna unit 8 to switch between at least 4 states.

[0154] For example, take an antenna pair consisting of antenna unit 1 (e.g., called E1) and antenna unit 2 (e.g., called E2). The four states of the antenna pair are as follows: Fig.14As shown. In state 1, RF channel RF1 is connected to E2, and the mobile phone receives and sends signals through E2. In state 2, RF channel RF2 is connected to E1, and the mobile phone receives and sends signals through E1. It can be seen that when switching from state 1 to state 2 (or from state 2 to state 1), due to the change of the working antenna, when the directional patterns of E1 and E2 are different, the directional pattern reconstruction of the antenna pair is achieved. In state 3, RF channel 2 is connected to E1 and E2 at the same time, and the mobile phone receives signals through E1 and E2 at the same time. It can be understood that in this state 3, since E1 and E2 work at the same time, the directional pattern of the antenna pair can be regarded as the superposition of the directional patterns of E1 and E2. Fig.15 The figure shows the distribution of the directional patterns in state 1, state 2 and state 3. Obviously, the result of the directional pattern superposition in state 3 is different from the directional pattern when E2 works alone in state 1 and the directional pattern distribution when E1 works alone in state 2. In other words, the directional pattern zero point in state 3 is different from the directional pattern zero point in state 1 or state 2. Therefore, the mobile phone can avoid the influence of the directional pattern zero point on the communication quality in the current communication state by switching between these three states. Fig.14 The antenna pair may also have a working state shown in state 4. In state 4, the radio frequency channel RF1 transmits and receives signals through E1, and the radio frequency channel RF2 transmits and receives signals through E2. Thus, when the frequency bands of the signals transmitted and received by the two channels are the same, dual-channel simultaneous transmission and reception are achieved, thereby achieving the effect of increasing throughput.

[0155] It should be noted that in order to achieve Fig.15 The directional pattern distribution effect shown in Figure 13-Figure 14 In the description, the two antenna units in the same antenna pair are arranged at symmetrical positions relative to the folding edge, so that when the two antennas work at the same time, the mutual influence between the two antennas can be reduced to achieve the best communication effect.

[0156] Combination Fig.10 According to the method shown, the mobile phone can determine the working state of the corresponding antenna according to the electrical parameters in the current communication. In this example, since the solution is used on a mobile phone with a folding screen, and the mobile phone is in different folding states (such as unfolded state and closed state), the communication environment of the antenna system is obviously different. Therefore, in some implementations of the present application, the mobile phone can also determine and adjust the working state of the antenna according to the current folding state. For example, when the mobile phone is in the unfolded state, the antenna system can be controlled to work in state 4. So that the mobile phone can provide a higher throughput for communication. For another example, when the mobile phone is in a closed state, the antenna system can be controlled to work in state 3. So that the mobile phone can improve the communication quality by avoiding the zero point of the directional pattern.

[0157] In some other implementations of the present application, two antenna units in the same antenna pair may also be arranged at asymmetric positions. Fig.16 , let's continue with the example of a mobile phone with 8 antenna units. Fig.16 In the example, Fig.16 As shown in (a), antenna unit 1, antenna unit 3, antenna unit 5, and antenna unit 7 are arranged on shell A. Antenna unit 2, antenna unit 4, antenna unit 6, and antenna unit 8 are arranged on shell B. When the mobile phone is in a closed state, the projections of the antenna units on the mobile phone on the screen are staggered. For example, refer to Fig.16 In (b), the projections of antenna unit 1 and antenna unit 2 are located on the upper part of the mobile phone in the closed state. Moreover, the projections of antenna unit 1 and antenna unit 2 do not overlap each other. Similarly, the projections of antenna unit 3 and antenna unit 4 are located on the side of the mobile phone in the closed state. The projections of antenna unit 3 and antenna unit 4 are located on the upper part of the mobile phone in the closed state. The projections of antenna unit 5 and antenna unit 6 are located on the side of the mobile phone in the closed state. The projections of antenna unit 5 and antenna unit 6 are located on the upper part of the mobile phone in the closed state. The projections of antenna unit 7 and antenna unit 8 are located on the side of the mobile phone in the closed state. The projections of antenna unit 7 and antenna unit 8 are located on the lower part of the mobile phone in the closed state.

[0158] In this example, two antennas may form antenna pairs. For example, antenna unit 1 and antenna unit 2 may form an antenna pair, antenna unit 3 and antenna unit 4 may form an antenna pair, antenna unit 5 and antenna unit 6 may form an antenna pair, and antenna unit 7 and antenna unit 8 may form an antenna pair.

[0159] It should be noted that, in this example, the RF module can provide a maximum of 6 multi-input and multi-output (MIMO) ports to achieve multi-input and multi-output communication. Among them, when antenna unit 1 (such as E1) works alone, it can be coupled to the corresponding RF channel as the main antenna (Main) to achieve the working effect of the main antenna. When antenna unit 2 (such as E2) works alone, it can be coupled to the RF channel corresponding to MIMO 3 to achieve the working effect of the frequency band corresponding to MIMO 3. When antenna unit 3 (such as E3) works alone, it can be coupled to the RF channel corresponding to diversity (Div) to achieve the working effect of the frequency band corresponding to Div. When antenna unit 4 (such as E4) works alone, it can be coupled to the RF channel corresponding to MIMO 4 to achieve the working effect of the frequency band corresponding to MIMO 4. When antenna unit 5 (such as E5) works alone, it can be coupled to the RF channel corresponding to MIMO 1 to achieve the working effect of the frequency band corresponding to MIMO 1. When antenna unit 6 (such as E6) works alone, it can be coupled with the RF channel corresponding to MIMO 5 to achieve the working effect of the frequency band corresponding to MIMO 5. When antenna unit 7 (such as E7) works alone, it can be coupled with the RF channel corresponding to MIMO 2 to achieve the working effect of the frequency band corresponding to MIMO 2. When antenna unit 8 (such as E8) works alone, it can be coupled with the RF channel corresponding to MIMO 6 to achieve the working effect of the frequency band corresponding to MIMO 6.

[0160] Combined with the above description of this scheme, Fig.16 The mobile phone shown can provide a variety of different working states to adapt to various communication environment requirements. For example, the mobile phone can control each antenna unit to be connected to the corresponding RF channel to achieve the normal operation of a single channel corresponding to a single antenna. Fig.17 , E1 is coupled to the RF channel corresponding to Main to radiate the main antenna. E2 is coupled to MIMO 3 to radiate the frequency band corresponding to MIMO 3. E3 is coupled to Div to radiate diversity. E4 is coupled to MIMO 4 to radiate the frequency band corresponding to MIMO 4. E5 is coupled to MIMO 1 to radiate the frequency band corresponding to MIMO 1. E6 is coupled to MIMO 5 to radiate the frequency band corresponding to MIMO 5. E7 is coupled to MIMO 2 to radiate the frequency band corresponding to MIMO 2. E8 is coupled to MIMO 6 to radiate the frequency band corresponding to MIMO 6. It can be seen that in this example, the 8 antenna units are respectively coupled to different RF channels, so a multi-input and output mechanism of up to 8*8 MIMO can be provided.

[0161] In addition to the above working states, the mobile phone can also control the antenna paths corresponding to E1-E8 to reconstruct the quantity and / or directional pattern to provide better communication quality.

[0162] The mobile phone can control the two antenna units in each antenna pair to couple to the same RF channel to achieve the directional pattern reconstruction of the antenna system. Fig.18 As shown, E1 and E2 can be connected to Main to achieve the reconstruction of the directional pattern of the main antenna, and overcome the degradation of communication quality caused by the zero point of the directional pattern of E1. Similarly, E3 and E4 can be connected to Div to achieve the reconstruction of the directional pattern of diversity, and overcome the degradation of communication quality caused by the zero point of the directional pattern of E3. E5 and E6 can be connected to MIMO 1 to achieve the reconstruction of the directional pattern of the antenna corresponding to MIMO 1, and overcome the degradation of communication quality caused by the zero point of the directional pattern of E5. E7 and E8 can be connected to MIMO 2 to achieve the reconstruction of the directional pattern of the main antenna corresponding to MIMO 2, and overcome the degradation of communication quality caused by the zero point of the directional pattern of E7. It can be seen that in this example, the 8 antenna units are respectively coupled to 4 RF channels, so a multi-input and output mechanism of up to 4*4 MIMO can be provided.

[0163] In addition, the mobile phone can also control the two antenna units in each antenna pair to reconfigure the quantity to achieve adaptive adjustment of the throughput rate. This solution is similar to the above example and will not be listed here one by one.

[0164] It should be understood that the above Figure 13-Figure 18 The description of the invention respectively gives examples of two antenna units in an antenna pair being symmetrical and asymmetrical about the folding axis. In other implementations of the present application, multiple antenna pairs in an electronic device may include antenna pairs with symmetrically arranged antenna units and antenna pairs with asymmetrically arranged antenna units. The specific selection rules can be flexibly selected according to the actual situation. In various compositions, the directional pattern reconstruction and quantity reconstruction methods of the antenna system are similar to those described in the above examples and will not be repeated here.

[0165] Fig.19 FIG. 1 is a schematic diagram showing the composition of an electronic device 1900. Fig.19 As shown, the electronic device 1900 may include: a processor 1901 and a memory 1902. The memory 1902 is used to store computer-executable instructions.
