Description

Antenna switching method and device

Technical field

This application relates to the field of communication technology, and in particular to an antenna switching method and device.

Background technique

At present, in order to meet different communication service requirements, multiple antennas may be provided in the terminal. Among them, for one antenna, one antenna is likely to be used to send and receive data of different standards. When multiple antennas work at the same time, interference may occur between the multiple antennas. Among them, the interference between antennas includes, but is not limited to, intermodulation interference and harmonic interference. When there are two or more transmission signals, the two or more transmission signals may modulate each other, thereby generating a new frequency signal output. If the new frequency falls within the working bandwidth of the receiver, it will cause interference to the received signal of the receiver. The interference caused by the signal generated by the mutual modulation of multiple signals to the receiver is called intermodulation interference. Taking Figure 1 as an example, a signal is sent at 1940MHz through one antenna, and a signal at 1980MHz is sent through another antenna. These two sending signals may generate a 1900MHz signal, which just falls into the reception of the left receiver. Frequency band, therefore, may cause intermodulation interference to the normal reception of the receiver. In another scenario, the harmonics of the transmitted signal (such as the first harmonic, the second harmonic, etc.) may fall into the receiving frequency band of the receiver, which will also affect the normal reception of the receiver. This kind of interference caused by the harmonics of the transmitted signal to the receiver is called harmonic interference.

It can be seen from the above content that when multiple antennas are provided in the terminal, there may be serious interference between the multiple antennas. Therefore, it is urgent to propose a technical solution to reduce interference between antennas.

Summary of the invention

The embodiments of the present application provide an antenna switching method and device, which can reduce interference between antennas. To achieve the foregoing objective, the following technical solutions are adopted in the embodiments of the present application.

After that, data is transmitted or received through at least two target antennas. Among them, the use state represents the relative relationship between the user and the device in space. In this way, when users and devices have different relative relationships in space, users in the near-field area of the antenna may have different influences on the antenna of the device, and the influence of the users on the interference between the antennas of the device may also be different. In the embodiments of this application, the user's influence on the device antenna is fully considered, and then according to the user's influence on the device antenna, multiple antennas for sending or receiving data are selected, so that the interference between the selected multiple antennas is relatively low. small.

In a possible design, determining at least two target antennas among the multiple candidate antennas of the device according to the use state includes: looking up a correspondence table according to the use state to determine a group of antennas as the at least two target antennas; wherein, the correspondence table It is used to indicate a group of antennas corresponding to each of the multiple usage states, and each group of antennas includes two or more antennas. In this way, the device can directly find the target antenna required for the current use state according to the configured correspondence table, without performing other complicated judgment logic, and reducing the complexity of the device's implementation.

If the first antenna transmits data and the second antenna receives data, the first harmonic, second harmonic, etc. generated by the transmitted signal of the first antenna may cause harmonic interference to the second antenna or other receiving antennas. By adopting the antenna switching method of the embodiment of the present application, since the influence of the user on the antenna is taken into consideration, the degree of interference between the selected at least two target antennas can be small.

For example, when taking a picture, the shutter is opened, and the light is transmitted to the photosensitive element of the camera through the lens, the light signal is converted into an electrical signal, and the photosensitive element of the camera transmits the electrical signal to the ISP for processing, which is converted into an image visible to the naked eye. ISP can also optimize the image focus, noise, brightness, and skin color. ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, the ISP may be provided in the camera 193.

The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and is projected to the photosensitive element. The photosensitive element may be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then transfers the electrical signal to the ISP to convert it into a digital image signal. ISP outputs digital image signals to DSP for processing. DSP converts digital image signals into standard RGB, YUV and other formats of image signals. In some embodiments, the mobile phone 100 may include one or N cameras 193, and N is a positive integer greater than one.

Digital signal processors are used to process digital signals. In addition to digital image signals, they can also process other digital signals. For example, when the mobile phone 100 selects a frequency point, the digital signal processor is used to perform Fourier transform on the energy of the frequency point.

Video codecs are used to compress or decompress digital video. The mobile phone 100 may support one or more video codecs. In this way, the mobile phone 100 can play or record videos in multiple encoding formats, such as: moving picture experts group (MPEG) 1, MPEG2, MPEG3, MPEG4, and so on.

NPU is a neural-network (NN) computing processor. By drawing on the structure of biological neural networks, for example, the transfer mode between human brain neurons, it can quickly process input information, and it can also continuously self-learn. Through the NPU, applications such as intelligent cognition of the mobile phone 100 can be implemented, such as image recognition, face recognition, voice recognition, text understanding, and so on.

The methods in the following embodiments can all be implemented in the mobile phone 100 having the above-mentioned hardware structure. It should be noted that the method of the following embodiment can also be applied to an electronic device or a component of an electronic device (such as a chip system) having a similar structure to FIG. 2. For example, an embodiment of the present application provides an antenna switching device. The device may be a stand-alone device located in the mobile phone 100 in FIG. 2. It may specifically include the mobile phone 100 or the processor 110, or may be a chip system in the device, including The processor 110 and other necessary components form a system, and the device mainly includes the processor 110 shown in FIG. 2. The device may also include a communication device (such as the radio frequency module 150 and the communication module 160 shown in FIG. 2), a storage device (such as the internal memory 121 shown in FIG. 2), and the like.

The embodiment of the present application provides an antenna switching method, which can be applied to an electronic device, or applied to a component (such as a chip system) in the electronic device. The following describes the antenna switching method of the embodiment of the present application mainly taking the electronic device as a mobile phone as an example. The device may be the previous mobile phone 100 or a component thereof, such as a chip system including a processor 110. As shown in Fig. 4, the antenna switching method includes S401-S403.

S401. The device obtains the use status of the device. As a possible implementation manner, one or more sensors may be used to detect the sensing data, and the use state of the device may be obtained according to the detected sensing data. The sensor can refer to the previous introduction, which will not be repeated here. Its function is mainly used to collect sensor data, that is, sensing data, so that the processor 110 can determine the use state according to the sensing data. The processor 110 may run necessary software, such as application software, to process the sensing data in order to obtain the usage status.

Among them, the use state represents the relative spatial relationship between the user who is using the device and the device. The spatial relative relationship between the user and the device includes but is not limited to one or a combination of the following: the relative position relationship between the user and the device, and the user The relative speed relationship with the device, the relative acceleration relationship between the user and the device, and the relative angular velocity relationship between the user and the device. The relative position relationship between the user and the device includes, but is not limited to, the distance between the user and the device and the angle (that is, the angle at which the device is held by the user). Exemplarily, the state of use of the device includes, but is not limited to, one or a combination of the following: static holding with left hand, static holding with right hand, static holding with both hands, horizontal holding, vertical holding, and left hand holding at the first speed. Holding, holding the right hand at the second speed, holding both hands at the third speed, rotating the left hand at the first angular speed, rotating the right hand at the second angular speed, rotating both hands at the third angular speed, holding the left hand at the first acceleration, holding the right hand at the first speed Two-acceleration holding, holding both hands at the third acceleration, the contact area and/or contact area of the palm with the device when holding with the left hand, the contact area and/or contact area of the palm with the device when holding with the right hand, and the palm when holding with both hands The contact area and/or contact area with the device.

As an example, sensing data can refer to data directly measured by sensors. For example, an ambient light sensor can measure ambient light, and the measured ambient light data can be called sensing data. Further, the processor may obtain the brightness of the ambient light from the ambient light sensor, so as to adjust the brightness of the display of the touch screen 104, or perform other mobile phone functions. For another example, the acceleration sensor can detect the magnitude of inertial force received by the mass in various directions (usually three axes), and can detect the magnitude and direction of gravity when it is stationary. The measured inertial force, gravity magnitude and direction can be measured It is called the sensing data of the acceleration sensor. Subsequently, based on the induction data of the mass in a certain direction and Newton's second law, the acceleration value of the mass in this direction can be calculated to infer the acceleration of the mobile phone relative to the user. Further, the acceleration value of the mobile phone relative to the user can be used for applications that recognize mobile phone gestures (such as horizontal and vertical screen switching, related games, magnetometer gesture calibration), vibration recognition related functions (such as pedometer, tapping), and so on.

S402. The device determines at least two target antennas among the multiple candidate antennas of the device according to the use status. Generally, the relative relationship between the mobile phone antenna and the user in space may be different in different use states of the mobile phone. Therefore, the user may have different influences on the radiation characteristics of the mobile phone antenna, resulting in the degree of interference between the mobile phone antennas under different use states. It may be different. The following exemplarily gives several usage states of the mobile phone, and analyzes the degree of interference between antennas in different usage states. Taking Figure 2 as an example, multiple candidate antennas can be antennas in antenna A, that is, antennas used to receive or transmit 2G/3G/4G/5G signals, or antennas in antenna B, that is, antennas used for receiving or transmitting Antennas for WLAN/BT/GNSS/FM/NFC signals.

In some embodiments, when the user holds the handshake, because the palm and the mobile phone have different contact areas and different contact areas when holding the handshake, different antennas on the mobile phone may be blocked, thereby affecting the radiation intensity of the blocked antennas, which in turn affects the radiation intensity of the blocked antennas. The degree of interference between the shielding antenna and other antennas. Take Figure 5 as an example, where, as shown in Figure 5 (a), when the user holds the handshake with both hands, the contact area between the palm of the hand and the mobile phone is area 1 and area 2, as shown in Figure 5 (b), the user single When the hand (right hand) holds the mobile phone, the contact area between the palm of the hand and the mobile phone is area 1. As the area of the contact area in Figure 5 (a) is larger than that in Figure 5 (b), it is compared to the area of the contact area in Figure 5 (b). In the use state shown in (b) in Figure 5, the mobile phone may block more antennas in the use state shown in Figure 5 (a). In these two use states, the degree of interference between the antennas of the mobile phone may be different . For another example, as shown in Figure 5(c), when the user holds the handshake with both hands, the contact area between the palm of the hand and the mobile phone is area 3 and area 4, compared with area 1 and area 2 shown in Figure 5(a) , Area 3 and Area 4 are closer to the top of the phone. If the mobile phone antenna is set close to the top, compared to the user's palm covering area 1 and area 2, when the user's palm covers area 3 and area 4, more antennas may be blocked, or in other words, the antenna may be blocked more. High, which in turn has a greater impact on the radiation intensity of the shielded antenna. In this way, in the use state shown in Figure 5 (a) and the use state shown in Figure 5 (c), the degree of interference between the antennas of the mobile phone may also be different. Similarly, in the use state shown in Figure 5 (d), the interference level between the antennas of the mobile phone is also affected by the contact area and contact area of the mobile phone touched by the user's palm.

In some embodiments, when the angle at which the mobile phone is held by the user is different, the angle of the mobile phone antenna relative to the ground plane may be different. As a result, the antenna may have different spatial radiation, such as different radiation intensity, radiation direction, etc. The degree of interference between antennas may also vary. As shown in (a-1) in Figure 6, the angle at which the mobile phone is held by the user is α, that is, the angle between the mobile phone and the ground plane is α; As shown in (b), the user can lift up and gradually raise the arm until the phone is approximately perpendicular to the ground (ie, hold it vertically) as shown in (c-1) in Figure 6. In the three mobile phone usage states shown in Figure 6 (a-1), Figure 6 (b), and Figure 6 (c-1), the degree of interference between the antennas of the mobile phone may be due to the holding of the mobile phone. The angle of the grip varies. You can also continue to refer to Figure 5(d). In the state of using the mobile phone shown in Figure 5(d), the mobile phone is approximately parallel to the horizon, that is, the mobile phone is held by the user approximately horizontally. In this case, the distance between the mobile phone antennas The degree of interference is not only affected by the contact area and area between the palm of the hand and the mobile phone, but may also be affected by the angle of the grip.

In some embodiments, when the mobile phone has different distances from the user, the antenna of the mobile phone and the user may also have different distances accordingly. Therefore, users in the near-field area of the mobile phone antenna may have different influences on the radiation characteristics of the antenna. In turn, the interference between the antennas may be different.

In some embodiments, when the mobile phone has different speeds and/or accelerations relative to the user, the distance between the mobile phone and the user may be different at the same time or time period. Therefore, the mobile phone may have a different degree of influence on the radiation characteristics of the antenna. , The degree of interference between antennas may also be different. Exemplarily, in some game scenarios, such as when the user is operating a virtual reality (VR) game, the relative speed and/or acceleration between the mobile phone and the user may change, and the mobile phone can respond to speed and/or acceleration. Change to dynamically switch the antenna group used. Similarly, when the mobile phone has different angular velocities relative to the user, the angle between the mobile phone and the user may be different at the same time or time period, so that the degree of interference between the antennas may also be different. The foregoing only exemplarily gives some possible use states of the device, and the use state of the device may also be other, and the embodiments of the present application will not be exhaustive.

According to the above, the degree of interference between mobile phone antennas may be different under different usage conditions. Therefore, it is considered that the multiple antennas used to transmit or receive data are selected according to the use state of the mobile phone, wherein the degree of interference between the selected multiple antennas is relatively small. For example, when the sensor detects the angle at which the mobile phone is held by the user as shown in Figure 6 (a-1), Figure 6 (b), and Figure 6 (c-1), the processor in the mobile phone The angle at which the mobile phone is held in these three situations can be obtained from the sensor, and when the mobile phone is held by the user at the angle shown in Figure 6 (a-1), select antenna group 1 as the antenna for sending or receiving data. Among them, in this state of use, the degree of interference between the antennas in the antenna group 1 is relatively small. Similarly, when the mobile phone is held by the user at the angle shown in Figure 6 (b), the processor selects antenna group 2 as the antenna for sending or receiving data. In the mobile phone, as shown in Figure 6 (c-1) When the angle is held by the user, the processor selects the antenna group 3 as the antenna for sending or receiving data.

As a possible implementation manner, through pre-testing, the degree of interference between every two antennas of the multiple antennas of the mobile phone in each use state can be obtained. Each use state and the degree of interference between every two antennas in the corresponding multiple antennas can be pre-configured in the device. Among them, the degree of interference between the two antennas can be expressed by the isolation between the two antennas. Isolation refers to the ratio of the transmit power of the transmit antenna to the power coupled (leaked) to the receive antenna by the transmit power. Generally, the power leaked from the transmitting power to the receiving antenna is less than the transmitting power. Therefore, the value of isolation is usually greater than one. Generally, the greater the value of the isolation between two antennas, the smaller the degree of interference between the two antennas.

Taking the isolation degree as an example of the degree of interference between antennas, the following Table 1 exemplarily shows the correspondence between the pre-configured use state and the isolation degree in the device:

Table 1

It can be seen from Table 1 that under normal circumstances, the isolation between each two antennas of the multiple antennas of the device is different under different usage conditions. For example, in the use state A, the isolation (X1) of the antenna 1 of the system A and the antenna 1 of the system B is different from the isolation (Y1) of the antenna 1 of the system A and the antenna 1 of the system B in the use state B, correspondingly Yes, in use state A and use state B, X2 is different from Y2, X3 is different from Y3, and X4 is different from Y4. Of course, under different usage conditions, there may also be two antennas with the same isolation. For example, the above X1 is the same as Y1, or X2 is the same as Y2, or X3 is the same as Y3, or X4 is the same as Y4. Among them, the system A and the system B shown in Table 1 may be systems of different communication standards. For example, system A is a 4G system, system B is a 5G system, system A uses the corresponding first antenna for transmission, and system B uses the corresponding second antenna for reception. The first and second antennas can be the antennas shown in Figure 2. Antenna in A. Of course, systems A and B can also be systems of the same communication standard. For example, both systems A and B are 4G communication standards as shown in FIG. 2.

In other embodiments, the degree of interference between the two antennas can also be expressed by the correlation coefficient between the two antennas. The specific introduction of the correlation coefficient can be found in the prior art. Or, it can also be expressed by other parameters. The embodiment of the present application does not limit the specific parameters used to indicate the degree of interference between antennas.

Based on the degree of interference between every two antennas in each use state and the corresponding multiple antennas of the mobile phone, for example, based on the above table 1, each use state can correspond to a group of antennas, and the group of antennas includes the smallest degree of mutual interference. N antennas, N is a positive integer greater than or equal to 2. Take the isolation degree as an example. Suppose there are 5 antennas on the mobile phone, namely antenna 1-antenna 5. In use state A, there are 10 available combinations of antennas, and each of the 5 antenna combinations The combined isolation is as follows: the isolation between antenna 1 and antenna 2 is 8, the isolation between antenna 1 and antenna 5 is 12, the isolation between antenna 2 and antenna 5 is 15, antenna 2 and antenna 3 The isolation between antenna 3 and antenna 4 is 10, and the isolation between antenna 3 and antenna 4 is 20. The isolation of the other 5 antenna combinations will not be listed one by one. In some embodiments, a set of antennas corresponding to each use state includes two antennas. Since the isolation between antenna 3 and antenna 4 is the largest, the set of antennas corresponding to use state A is antenna 3 and antenna 4. In other embodiments, a group of antennas corresponding to each use state includes more than two antennas. That is to say, in a certain state of use, the device can also select more than two antennas to receive or transmit data of one or more communication standards according to the current communication requirements. In this way, it is possible to use more antennas to send and receive signals to obtain greater The transmission bandwidth. For example, in a certain use state, the device selects antenna 1 to antenna 4 as a group of antennas corresponding to the use state. Antenna 1 to antenna 4 are used to process 5G signals, where the signal frequency band of antenna 1 and the signal frequency band of antenna 2 are subjected to carrier aggregation (CA) to obtain a larger transmission bandwidth. For another example, antenna 1 and antenna 2 are used to process 5G signals, and antenna 3 and antenna 4 are used to process 4G signals. In this case, suppose that 4 antennas need to be selected as the antennas to be used by the device in use state A. Among the above antennas 1 to 5, due to the isolation between antenna 3 and antenna 4, and the isolation between antenna 2 and antenna 5. The degree of isolation has the largest value among the above-mentioned isolation degrees. A group of antennas corresponding to the use state A can be antenna 2, antenna 5, antenna 3, and antenna 4. Subsequently, when the mobile phone detects that the mobile phone is in a certain use state, a group of antennas with the smallest degree of mutual interference (for example, the largest isolation) corresponding to the use state is used as antennas for sending or receiving data. Specifically, the mobile phone selects the antenna according to the use state, which can be implemented as: the mobile phone searches the corresponding table according to the use state of the mobile phone to determine a group of antennas as at least two target antennas for sending or receiving data.

The at least two target antennas selected by the mobile phone include a first antenna and a second antenna. The first antenna is used for sending data, and the second antenna is used for sending or receiving data. That is to say, at least one antenna for transmitting data is included in the at least two antennas. Wherein, if the first antenna transmits data and the second antenna transmits data, the transmitted signals of the first antenna and the second antenna may produce intermodulation, which will affect the normal reception of the first antenna and/or the second antenna, or The modulated signal may also cause intermodulation interference to other receiving antennas. If the first antenna transmits data and the second antenna receives data, the first harmonic, second harmonic, etc. generated by the transmitted signal of the first antenna may cause harmonic interference to the second antenna or other receiving antennas. Based on the above-mentioned embodiments of this application, the at least two target antennas selected by the device are a group of antennas with the least degree of mutual interference. Therefore, both the first antenna and the second antenna (multiple antennas) are used as the transmit antennas to generate intermodulation. The interference, or the harmonic interference generated by only the first antenna as the transmitting antenna, can ensure the minimum degree of interference.

It should also be noted that the first antenna and the second antenna may be respectively used to receive or transmit data of the same or different communication standards. For example, the at least two target antennas include antenna 1 of system A and antenna 2 of system B in Table 1. System A is an LTE communication system, system B is a WCDMA communication system, and antenna 1 is used for receiving or transmitting. For data of the LTE communication standard, the antenna 2 is used to receive or transmit data of the WCDMA communication standard. For another example, the at least two target antennas include the antenna 1 and the antenna 2 of the system A in Table 1 above, and the antenna 1 and the antenna 2 are used to receive or send the data of the system A. System A may be 2G or 3G or 4G or 5G as shown in FIG. 2, or BT or WLAN or GNSS or NFC or IR or FM. The above is only an example, and the specific communication system is only an example.

The corresponding table searched above is used to indicate a group of antennas corresponding to each of the multiple usage states, and each group of antennas includes two or more antennas. For a certain use state, a set of antennas corresponding to the use state is a set of antennas with the least degree of mutual interference in the use state. As shown in Table 2 below, which is an exemplary implementation of the correspondence table, the processor 110 directly obtains the antenna combination corresponding to the optimal interference situation of the use state by looking up the table, without other complicated judgment and selection logic. Among them, use state A corresponds to antenna 1 and antenna 2, indicating that the degree of interference between antenna 1 and antenna 2 is the smallest in use state A. Here, there is no need to further list other antenna combinations with non-optimal interference conditions. Similarly, use state B corresponds to antenna 1, antenna 2, and antenna 4, indicating that in use state B, the degree of mutual interference between antenna 1, antenna 2 and antenna 4 is the smallest.

Table 2

Take the use shown in Figure 5 (a-1) as an example. When the mobile phone processor learns from the sensor that the mobile phone is held by the user at the angle shown in Figure 5 (a-1), the processor looks up the above Table 2 and determines The use state is use state A, and the antenna 1 and antenna 2 corresponding to use state A are determined as target antennas for sending or receiving data. These two antennas are used to process data of the same or different standards.

S403. The device sends or receives data through at least two target antennas. Specifically, the device receives or transmits data of multiple different communication standards through at least two target antennas. For example, at least two target antennas include antenna 1 and antenna 2. Antenna 1 is used to transmit or receive data of a first communication standard, and antenna 2 is used to transmit or receive data of a second communication standard. The first communication standard and the second communication standard may be the same or different. Specifically, the processor 110 may control the antennas 1 and 2 to perform data transmission or reception.

As a possible implementation manner, in S403, the processor 110 shown in FIG. 2 controls at least two target antennas to transmit or receive data.

In the antenna switching method provided by the embodiments of the present application, a device obtains the use status of the device, determines at least two target antennas among multiple candidate antennas of the device according to the use status, and transmits or receives data through the at least two target antennas. Among them, because the use state represents the relative relationship between the user and the device in space, when the user and the device have a different relative relationship in space, the users in the antenna near-field area may have a different degree of influence on the device antenna, and then the user has a different effect on the device antenna. The impact of the degree of interference between may also be different. In the embodiments of this application, the user's influence on the device antenna is fully considered, and then according to the user's influence on the device antenna, multiple antennas for sending or receiving data are selected, so that the interference between the selected multiple antennas is relatively low. small.

The following describes the solutions of the embodiments of the present application in combination with specific examples to facilitate readers' further understanding. First, take the application of the antenna switching method of the embodiment of the present application in a carrier aggregation scenario as an example, that is, a mobile phone selects multiple antennas for transmitting and receiving signals of the communication standard under a certain communication standard. Referring to Figure 7, it is assumed that the mobile phone includes a multi-system public control center, five antennas of system A, namely antenna 1, antenna 2, antenna 4 to antenna 6 of system A as shown in Figure 7, and GPS as shown in Figure 7. Antenna 3. Among them, antenna 1, antenna 4, and antenna 5 can send and receive signals in the frequency range of (band 42) band42, antenna 2 and antenna 6 can both send and receive signals in the frequency range of (band 1) band1, and antenna 3 can receive 1575MHz signal of. The multi-system public control center, as a functional module set on the mobile phone, can be used to control the switching antenna, and specifically includes the processor 110, and may further include other necessary components. Or a multi-system common control center may exist as a part of the processor 110, and specifically may be hardware in the processor 110 or a software module running on the processor 110. In one example, the multi-system common control center is equivalent to the processor 110.

When the mobile phone is performing data transmission, multiple carriers can be aggregated through the in-band (inter) carrier aggregation technology to obtain a larger transmission bandwidth. Among them, the aggregation (frequency band) band1 and band42 are taken as an example for description here. band1: 1920-1980MHz, band42: 3400MHz-3600MHz. If there are two or more transmitting antennas, such as the first antenna and the second antenna, the frequency of the transmitted signal of the first antenna falls into band1, and the frequency of the transmitted signal of the second antenna falls into band42, then the transmitted signal of the first antenna and The signal transmitted by the second antenna may produce intermodulation, and the frequency range of the intermodulation signal is between 1420-1680 MHz. Assuming that the GPS receiving frequency is 1575MHz, the intermodulation signal may fall into the receiving antenna, causing intermodulation interference to the receiving antenna.

In order to reduce the impact of the above-mentioned intermodulation interference, an embodiment of the present application provides an antenna switching solution. When the mobile phone has data (such as uplink (UL) data) transmission, the mobile phone obtains the current use status of the mobile phone through the sensor, and can According to the correspondence between each usage state and the isolation between the antennas pre-configured in the mobile phone, for example, according to Table 1, the isolation between every two antennas that meets the current carrier aggregation requirements is obtained. Taking the aggregation of band1 and band42 as an example, the two antennas that meet the current carrier aggregation requirements include an antenna capable of transmitting and receiving band42 signals and an antenna capable of transmitting and receiving band1 signals. Specifically, for example, the mobile phone detects that the mobile phone is currently in a certain state of use, and determines that band1 and band42 need to be aggregated according to the current communication requirements, that is, it is determined that the two antennas that meet the current carrier aggregation requirements include antenna 1 as shown in Figure 7. And antenna 2, antenna 1 and antenna 6, antenna 4 and antenna 2, antenna 4 and antenna 6, antenna 5 and antenna 2, antenna 5 and antenna 6. After that, the mobile phone determines the isolation between every two antennas that meet the current carrier aggregation requirements in the use state according to Table 1, for example: the isolation between antenna 1 and antenna 2 is 15, and the difference between antenna 1 and antenna 6. The isolation between antenna 4 and antenna 2 is 20, the isolation between antenna 4 and antenna 2 is 12, the isolation between antenna 4 and antenna 6 is 8, the isolation between antenna 5 and antenna 2 is 18, and the isolation between antenna 5 and antenna The isolation between 6 is 25. Furthermore, the mobile phone can select two antennas with greater isolation as the antennas used for carrier aggregation according to the isolation between every two antennas that meet the current carrier aggregation requirements. In this way, the possibility of intermodulation between the two antennas of the selected system A is reduced, and further, the interference of the intermodulation signal on the GPS antenna 3 as shown in FIG. 7 is reduced.

As a possible implementation, considering the different carrier aggregation requirements, the actual antennas used by the mobile phone may be different, and the correspondence table can also indicate a group corresponding to each of the multiple usage states under different CA requirements. antenna. For example, for a certain use state, the corresponding table indicates that when band1 and band42 need to be aggregated, the use state corresponds to antenna group 1, and when band1 and band2 need to be aggregated, the use state corresponds to antenna group 2. In other words, the above-mentioned correspondence table can also be specifically implemented as the following Table 3:

table 3

Combining a specific example, the mobile phone detects that the current use state is use state A, and the current carrier aggregation requirements are aggregated band1 and band42. After that, the mobile phone looks up the corresponding table 3 according to the use state A and the current carrier aggregation requirements, and it can be learned that when band1 and band42 need to be aggregated, the group of antennas corresponding to the use state A is antenna group 1. Subsequently, the mobile phone is switched to antenna group 1 through the multi-system public control center, and the mobile phone can transmit data through multiple antennas of antenna group 1. Assume that antenna group 1 includes antenna 1 and antenna 2. The mobile phone implements carrier aggregation through antenna 1 and antenna 2. As described above, generally, the isolation between antenna 1 and antenna 2 selected by the mobile phone is relatively large. Thus, when both antenna 1 and antenna 2 are used to transmit signals, the antenna The transmission signal of 1 and the transmission signal of the antenna 2 are not easy to generate an intermodulation signal, which reduces the intermodulation interference of the GPS antenna 3 shown in FIG. 7 by the intermodulation signal. When one antenna of antenna 1 and antenna 2 is used to transmit signals, and the other antenna is used to receive signals, for example, antenna 1 is used to transmit signals and antenna 2 is used to receive signals, because the isolation between antenna 1 and antenna 2 is relatively high. Therefore, the harmonics generated by the antenna 1 interfere with the harmonics of the antenna 2 less.

In some other embodiments, the antenna switching method of the embodiment of the present application is applied to a multi-connection scenario of a different system as an example, that is, the mobile phone works in two or more communication modes, and is selected to send and receive the two or more communications. Multiple antennas for standard signals.

As a possible implementation, considering that the antenna actually used by the mobile phone may be different when working in different communication standards, the correspondence table can also indicate that each of the multiple use states corresponds to each of the different communication standards. A set of antennas. For example, for a certain use state, the correspondence table indicates that when it needs to work in LTE and NR standards, the use state corresponds to antenna group 1, and when it needs to work in LTE and WCDMA, the use state corresponds to antenna group 2. In other words, the above correspondence table can also be specifically implemented as the following Table 4:

Table 4

With reference to specific examples, the mobile phone determines that the current use state is use state A through the sensing data obtained by the sensor, and the mobile phone determines that the current communication demand is to work in LTE and NR standards. After that, the mobile phone searches the above-mentioned correspondence table 4 according to the use state A and current communication requirements, and it can be learned that when it needs to work in LTE and NR, the group of antennas corresponding to the use state A is antenna group 1. Later, the mobile phone can transmit data through multiple antennas of antenna group 1. Assume that antenna group 1 includes antenna 1 and antenna 2. Among them, the mobile phone transmits and receives LTE signals through antenna 1, and transmits and receives NR signals through antenna 2. As described above, the isolation between antenna 1 and antenna 2 selected by the mobile phone is usually large. The transmission signal of 2 is not easy to generate an intermodulation signal, which reduces the intermodulation interference of the intermodulation signal to other antennas. Moreover, when the isolation between the antenna 1 and the antenna 2 is large, the transmission signal of the antenna 1 is unlikely to cause harmonic interference to the antenna 2, and the transmission signal of the antenna 2 is not likely to cause harmonic interference to the antenna 1.

It can be understood that, in order to implement the foregoing functions, the devices in the embodiments of the present application include hardware structures and/or software modules corresponding to each function.
