Description

Antenna switching method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an antenna switching method and apparatus.

Background

Currently, in order to meet different communication service requirements, a terminal may be provided with multiple antennas. For one antenna, one antenna is likely to be used for receiving and transmitting data of different standards. When a plurality of antennas are operated simultaneously, interference may occur between the plurality of antennas. Among them, the inter-antenna interference includes, but is not limited to, intermodulation interference and harmonic interference. When there are two or more transmit signals, the two or more transmit signals may be modulated with each other, thereby producing a new frequency signal output. If the new frequency falls well within the operating bandwidth of the receiver, interference will be caused to the received signal of the receiver. Such interference caused to the receiver by signals resulting from intermodulation of the multiple signals is referred to as intermodulation interference. Taking fig. 1 as an example, a signal is sent at 1940MHz through one antenna, and a signal is sent at 1980MHz through the other antenna, the two sending signals may generate a 1900MHz signal, and the 1900MHz signal just falls into the receiving frequency band of the left receiver, so that intermodulation interference may be caused to normal reception of the receiver. In another scenario, harmonics (e.g., first harmonic, second harmonic, etc.) of the transmitted signal may fall into the receiving frequency band of the receiver, which may also affect the normal reception of the receiver. This interference to the receiver due to the harmonics of the transmitted signal is known as harmonic interference.

As can be seen from the above, when a plurality of antennas are provided in a terminal, a serious interference phenomenon may exist between the plurality of antennas. Therefore, a technical solution for reducing interference between antennas is needed.

Disclosure of Invention

The embodiment of the application provides an antenna switching method and device, which can reduce interference among antennas. In order to achieve the above purpose, the following technical solutions are adopted in the embodiments of the present application.

The method comprises the following steps: the method comprises the steps of obtaining the using state of the equipment, and determining at least two target antennas among a plurality of candidate antennas of the equipment according to the using state. Thereafter, data is transmitted or received through at least two target antennas. Wherein the usage status represents the relative relationship of the user and the device in space. As such, when the user and the device have different relative relationships in space, the degree of influence of the user at the antenna near-field region on the device antenna may be different, and thus the degree of influence of the user on the interference between the device antennas may also be different. In the embodiment of the application, the influence of the user on the equipment antenna is fully considered, and then the plurality of antennas for transmitting or receiving data are selected according to the influence degree of the user on the equipment antenna, so that the interference degree among the selected plurality of antennas is smaller.

In one possible design, determining at least two target antennas among a plurality of candidate antennas of a device according to a usage state includes: looking up a corresponding table according to the use state to determine a group of antennas as at least two target antennas; the corresponding table is used for indicating a group of antennas corresponding to each of a plurality of using states, and each group of antennas comprises two or more antennas. Therefore, the device can directly search the target antenna required to be used in the current use state according to the configured corresponding table, and other complex judgment logic is not required to be executed, so that the implementation complexity of the device is reduced.

In one possible design, the acquiring the usage status of the device includes: sensing data is acquired by one or more sensors and a state of use of the device is acquired based on the sensing data.

For example, two target antennas are selected, and both target antennas are antennas for receiving or transmitting 4G signals. Of course, the at least two target antennas may also be antennas for receiving or transmitting signals of different communication schemes. For example, two target antennas are selected, one for receiving or transmitting 4G signals and the other for transmitting or receiving 5G signals.

In one possible design, the at least two target antennas include a first antenna for transmitting data and a second antenna for transmitting data or receiving data. When the first antenna is used for transmitting data and the second antenna is used for transmitting data, the transmitting signal of the first antenna and the transmitting signal of the second antenna may generate intermodulation signals, and the intermodulation signals may affect normal reception of the first antenna and/or the second antenna, or the intermodulation signals may also generate intermodulation interference to other receiving antennas. If the first antenna transmits data and the second antenna receives data, the first harmonic, the second harmonic, and the like generated by the transmission signal of the first antenna may generate harmonic interference to the second antenna or other receiving antennas. By adopting the antenna switching method, the interference degree between the at least two selected target antennas can be smaller due to the consideration of the influence of the user on the antennas.

The ISP is used to process data fed back by the camera 193. For example, when photographing, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing, so that the electrical signal is converted into an image visible to naked eyes. ISP can also perform algorithm optimization on the focus, noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in the camera 193.

The camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image onto the photosensitive element. The photosensitive element may be a charge coupled device (charge coupled device, CCD) or a Complementary Metal Oxide Semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, which is then transferred to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV, or the like format. In some embodiments, the cell phone 100 may include 1 or N cameras 193, N being a positive integer greater than 1.

The digital signal processor is used for processing digital signals, and can process other digital signals besides digital image signals. For example, when the handset 100 selects a frequency bin, the digital signal processor is used to fourier transform the frequency bin energy, etc.

Video codecs are used to compress or decompress digital video. The handset 100 may support one or more video codecs. In this way, the mobile phone 100 can play or record video in multiple coding formats, for example: dynamic picture experts group (moving picture experts group, MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

The NPU is a neural-network (NN) computing processor, and can rapidly process input information by referencing a biological neural network structure, for example, referencing a transmission mode between human brain neurons, and can also continuously perform self-learning. Applications such as intelligent cognition of the mobile phone 100 can be realized through the NPU, for example: image recognition, face recognition, speech recognition, text understanding, etc.

The methods in the following embodiments may be implemented in the mobile phone 100 having the above-described hardware structure. It should be noted that the method of the following embodiments may also be applied to an electronic device having a similar structure to that of fig. 2 or a component (such as a chip system) of the electronic device. For example, the embodiment of the present application provides an antenna switching apparatus, which may be a stand-alone device, and is located in the mobile phone 100 of fig. 2, and 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, so as to form a system, where the apparatus mainly includes the processor 110 shown in fig. 2. The apparatus may also include a communication device (such as the radio frequency module 150, the communication module 160, etc. shown in fig. 2), a storage device (such as the internal memory 121 shown in fig. 2), etc.

The embodiment of the application provides an antenna switching method, which can be applied to electronic equipment or components (such as a chip system) in the electronic equipment. The antenna switching method of the embodiments of the present application will be described in detail below mainly using an electronic device as an example of a mobile phone, where the device may be the mobile phone 100 or a component thereof, such as a chip system including the processor 110. As shown in fig. 4, the antenna switching method includes S401 to S403.

S401, the device acquires the use state of the device. As one possible implementation, the sensing data may be detected by one or more sensors and the status of use of the device may be obtained from the detected sensing data. The sensor may refer to the previous description, and its function is mainly to collect sensor data, i.e. sensing data, so that the processor 110 determines the usage status according to the sensing data. The processor 110 may run the necessary software, such as application software, to process the sensed data to obtain the usage status.

Wherein the usage status represents a spatial relative relationship of a user using the device to the device, including, but not limited to, a combination of one or more of the following: the relative position relationship between the user and the device, the relative speed relationship between the user and the device, the relative acceleration relationship between the user and the device, and the relative angular speed relationship between the user and the device. The relative positional relationship of the user and the device includes, but is not limited to, distance, angle (i.e., the angle at which the device is held by the user) relationship between the user and the device. Exemplary usage states of the device include, but are not limited to, combinations of one or more of the following: the left hand is held stationary, the right hand is held stationary, the both hands are held stationary, the horizontal is held, the vertical is held, the left hand is held at a first speed, the right hand is held at a second speed, the both hands are held at a third speed, the left hand is rotated at a first angular speed, the right hand is rotated at a second angular speed, the both hands are rotated at a third angular speed, the left hand is held at a first acceleration, the right hand is held at a second acceleration, the both hands are held at a third acceleration, the contact area and/or contact area of the palm with the device when the left hand is held, the contact area and/or contact area of the palm with the device when the right hand is held, and the contact area and/or contact area of the palm with the device when the both hands are held.

By way of example, sensed data may refer to data measured directly by a sensor. For example, an ambient light sensor may measure ambient light, and the measured ambient light data may be referred to as sensed data. Further, the processor may obtain ambient light from the ambient light sensor in order to adjust the brightness of the display of the touch screen 104 or perform other cell phone functions. For example, the acceleration sensor may detect the inertial force of the mass block in all directions (generally three axes), and the gravity force and direction may be detected when the mass block is stationary, and the measured inertial force, gravity force and direction may be referred to as sensing data of the acceleration sensor. Then, based on the sensing data such as the inertia force and the like of the mass block in a certain direction and Newton's second law, the acceleration value of the mass block in the direction can be calculated so as to estimate 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 for recognizing the gesture of the mobile phone (such as horizontal-vertical screen switching, related games, magnetometer gesture calibration), vibration recognition related functions (such as pedometer and knocking), and the like.

S402, the device determines at least two target antennas in a plurality of candidate antennas of the device according to the use state. In general, the relative relationship between the mobile phone antenna and the user in space may be different in different usage states of the mobile phone, so that the degree of influence of the user on the radiation characteristics of the mobile phone antenna may be different, so that the degree of interference between the mobile phone antennas may be different in different usage states. Several usage states of the mobile phone are given as examples below, and the interference degree between antennas in different usage states is analyzed. Taking fig. 2 as an example, the multiple candidate antennas may be antennas in the antenna a, that is, antennas for receiving or transmitting signals of 2G/3G/4G/5G, or antennas in the antenna B, that is, antennas for receiving or transmitting signals of WLAN/BT/GNSS/FM/NFC, or the like.

In some embodiments, when a user holds a mobile phone, different antennas on the mobile phone may be blocked due to different contact areas and different contact areas between the palm and the mobile phone when the user holds the mobile phone, so as to influence the radiation intensity of the blocked antennas and further influence the interference degree between the blocked antennas and other antennas. Taking fig. 5 as an example, when the user holds the mobile phone with both hands as shown in fig. 5 (a), the contact area between the palm and the mobile phone is the area 1 and the area 2, and when the user holds the mobile phone with one hand (right hand) as shown in fig. 5 (b), the contact area between the palm and the mobile phone is the area 1, and since the contact area of (a) in fig. 5 is larger than the contact area of (b) in fig. 5, the mobile phone may block more antennas in the use state shown in (a) in fig. 5 than in the use state shown in (b) in fig. 5, and the interference degree between the antennas of the mobile phone may be different in the two use states. For another example, as shown in fig. 5 (c), when the user holds the mobile phone with both hands, the contact area between the palm and the mobile phone is the area 3 and the area 4, and the area 3 and the area 4 are closer to the top of the mobile phone than the area 1 and the area 2 shown in fig. 5 (a). If the mobile phone antenna is disposed at a position close to the top, compared with the user palm shielding area 1 and the user palm shielding area 2, when the user palm shielding area 3 and the user palm shielding area 4 may shield more antennas, or the shielding degree of the antenna is higher, and the influence on the radiation intensity of the shielded antenna is larger. In this way, the interference level between the mobile phone antennas may be different between the use state shown in fig. 5 (a) and the use state shown in fig. 5 (c). Similarly, in the use state shown in fig. 5 (d), the interference degree between the mobile phone antennas is also affected by the contact area and the contact area of the mobile phone contacted by the palm of the user.

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 with respect to the ground plane may be different, so that the antennas may have different spatial radiation, such as different radiation intensities, radiation directions, and the like, and thus the interference degree between the antennas may also be different. As shown in (a-1) of fig. 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; then, as shown in fig. 6 (a-1) -6 (b), the user can lift the arm gradually until the mobile phone is approximately perpendicular to the ground (i.e., held vertically) as shown in fig. 6 (c-1). In the three mobile phone use states shown in fig. 6 (a-1), 6 (b), and 6 (c-1), the interference degree between the mobile phone antennas may be different according to the angle at which the mobile phone is held. Still further, referring to fig. 5 (d), in the use state of the mobile phone shown in fig. 5 (d), the mobile phone is approximately parallel to the horizon, that is, the mobile phone is held approximately horizontally by the user, in this case, the interference degree between the mobile phone antennas is not only affected by the contact area and area between the palm and the mobile phone, but also possibly affected by the holding angle.

In some embodiments, when the mobile phone has different distances relative to the user, the mobile phone antenna and the user may have different distances, so that the influence degree of the user in the near field region of the mobile phone antenna on the radiation characteristic of the antenna may be different, and thus the interference between the antennas may be different.

In some embodiments, when the mobile phone has different speeds and/or accelerations with respect to the user, the distance between the mobile phone and the user may be different at the same time or period, and thus, the degree of influence of the mobile phone on the radiation characteristics of the antennas may be different, and the degree of interference between the antennas may also be different. For example, in some game scenarios, such as when a user operates a Virtual Reality (VR) game, the relative speed and/or acceleration between the handset and the user may change, and the handset may dynamically switch the antenna set used in response to the change in speed and/or acceleration. Similarly, when the handset has different angular velocities relative to the user, the angle between the handset and the user may be different at the same time or period, and thus the degree of interference between the antennas may be different. The foregoing merely illustrates some possible usage states of the device, and the usage states of the device may be other, which is not exhaustive in the embodiments of the present application.

According to the above, the interference level between the mobile phone antennas may be different in different use states. Therefore, it is considered that a plurality of antennas used for transmitting or receiving data are selected according to the use state of the mobile phone, wherein the interference degree between the selected plurality of antennas is small. For example, when the sensor detects that the angle of the mobile phone is held by the user is shown as (a-1) in fig. 6, (b) in fig. 6, and (c-1) in fig. 6, respectively, the processor in the mobile phone can obtain the angle of the mobile phone held by the user in these three cases from the sensor, and select the antenna group 1 as the antenna for transmitting or receiving data when the mobile phone is held by the user at the angle shown as (a-1) in fig. 6, wherein in such a use state, the interference degree between the antennas in the antenna group 1 is small. Similarly, the processor selects the antenna group 2 as an antenna for transmitting or receiving data when the angle of the mobile phone is held by the user as shown in (b) of fig. 6, and selects the antenna group 3 as an antenna for transmitting or receiving data when the angle of the mobile phone is held by the user as shown in (c-1) of fig. 6.

As a possible implementation manner, the interference degree between every two antennas in the multiple antennas of the mobile phone under each use state can be obtained through a pre-test. Each usage state and the degree of interference between each two of the corresponding plurality of antennas may be preconfigured in the device. Wherein the degree of interference between two antennas can be expressed in terms of the isolation between the two antennas. Isolation refers to the ratio of the transmit power of a transmit antenna to the power of the transmit power coupled (leaked) to a receive antenna. Typically, the power of the transmit power leaking to the receive antenna is less than the transmit power, and therefore the value of the isolation is typically greater than 1. In general, a larger value of the isolation between two antennas indicates a smaller degree of interference between the two antennas.

Taking isolation as an example to represent the interference level between antennas, table 1 below exemplarily shows the correspondence between the preconfigured use state in the device and the isolation:

TABLE 1

As can be seen from table 1, in general, the isolation between each two antennas of the plurality of antennas of the device is different in different use states. For example, in the use state a, the isolation (X1) between the antenna 1 of the system a and the antenna 1 of the system B is different from the isolation (Y1) between the antenna 1 of the system a and the antenna 1 of the system B in the use state B, and accordingly, in the use state a and the use state B, X2 is different from Y2, X3 is different from Y3, and X4 is different from Y4. Of course, in different use states, there may be two antennas with the same isolation. For example, X1 is the same as Y1, X2 is the same as Y2, X3 is the same as Y3, or X4 is the same as Y4. The system a and the system B shown in table 1 may be systems of different communication systems. For example, the system a is a system of a 4G system, the system B is a system of a 5G system, the system a uses a corresponding first antenna to transmit, the system B uses a corresponding second antenna to receive, and the first antenna and the second antenna may be antennas in the antenna a shown in fig. 2. Of course, the system A, B may also be a system of the same communication system. For example, the systems A, B are all 4G communication systems as shown in fig. 2.

In other embodiments, the degree of interference between two antennas may also be expressed in terms of a correlation coefficient between the two antennas. For a specific description of the correlation coefficient, reference is made to the prior art. Alternatively, other parametric representations may be used. The embodiment of the application does not limit what parameters are specifically used to represent the interference degree between antennas.

Based on each usage state and the interference level between each two antennas in the corresponding multiple antennas of the mobile phone, for example, based on the above table 1, each usage state may correspond to a group of antennas, where the group of antennas includes N antennas with the smallest interference level between each other, and N is a positive integer greater than or equal to 2. Taking the interference degree as an example by using isolation degree, assuming that 5 antennas, namely antennas 1 to 5, are arranged on the mobile phone, in a use state A, the available combination of the antennas is 10, wherein the isolation degree of each antenna combination of the 5 antenna combinations 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, the isolation between antenna 2 and antenna 3 is 10, and the isolation between antenna 3 and antenna 4 is 20. The isolation of the other 5 antenna combinations is not listed one by one. In some embodiments, the set of antennas corresponding to each usage state includes two antennas, and since the isolation between antenna 3 and antenna 4 is the greatest, the set of antennas corresponding to usage state a is antenna 3 and antenna 4. In other embodiments, a set of antennas corresponding to each use state includes more than two antennas. That is, in a certain use state, the device may also select more than two antennas according to the current communication requirement to respectively receive or transmit data of one or more communication systems, so that a larger transmission bandwidth can be obtained by using more antennas to send and receive signals. For example, in a certain use state, the device selects the antennas 1 to 4 as a group of antennas corresponding to the use state. The antennas 1 to 4 are used for processing 5G signals, wherein the signal frequency band of the antenna 1 and the signal frequency band of the antenna 2 are subjected to carrier aggregation (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, it is assumed that 4 antennas are selected as antennas to be used by the device in the use state a, and among the antennas 1 to 5, since the isolation between the antenna 3 and the antenna 4 and the isolation between the antenna 2 and the antenna 5 are the largest in the plurality of isolation values, a group of antennas corresponding to the use state a may be the antenna 2, the antenna 5, the antenna 3 and the 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 mutual interference degree (such as the largest isolation degree) corresponding to the use state is used as an antenna for transmitting or receiving data. Specifically, the mobile phone selects the antenna according to the use state, and can be implemented as follows: the mobile phone searches the corresponding table according to the using state of the mobile phone to determine a group of antennas as at least two target antennas for transmitting or receiving data.

The mobile phone comprises at least two target antennas selected by the mobile phone, wherein the at least two target antennas comprise a first antenna and a second antenna, the first antenna is used for transmitting data, and the second antenna is used for transmitting or receiving data. That is to say that at least two antennas comprise at least one antenna for transmitting data. If the first antenna transmits data and the second antenna transmits data, the transmission signals of the first antenna and the second antenna may generate intermodulation, which affects normal reception of the first antenna and/or the second antenna, or the intermodulation signal may also generate intermodulation interference to other receiving antennas. If the first antenna transmits data and the second antenna receives data, the first harmonic, the second harmonic, and the like generated by the transmission signal of the first antenna may generate harmonic interference to the second antenna or other receiving antennas. Based on the embodiments described above, at least two target antennas selected by the device are a group of antennas with the smallest mutual interference degree, so that the minimum interference degree can be ensured whether the first antenna and the second antenna (multiple antennas) are jointly used as intermodulation interference generated by the transmitting antenna or only the first antenna is used as harmonic interference generated by the transmitting antenna.

It should be noted that, the first antenna and the second antenna may be used to receive or transmit data in the same or different communication systems, respectively. For example, the at least two target antennas include the antenna 1 of the system a and the antenna 2 of the system B in table 1, where the system a is a system of LTE communication system, the system B is a system of WCDMA communication system, the antenna 1 is used for receiving or transmitting data of LTE communication system, and the antenna 2 is used for receiving or transmitting data of WCDMA communication system. For another example, the at least two target antennas include the antenna 1 and the antenna 2 of the system a in the above table 1, and the antenna 1 and the antenna 2 are used to receive or transmit 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 are merely examples, and specific communication schemes are merely examples.

The above-mentioned searched corresponding table is used for indicating a group of antennas corresponding to each of a plurality of use states, and each group of antennas comprises two or more antennas. For a certain use state, the group of antennas corresponding to the use state is the group of antennas with the smallest mutual interference degree in the use state. As shown in table 2 below, for one exemplary implementation of the correspondence table, the processor 110 directly obtains the antenna combination corresponding to the optimal interference condition for the use state through a look-up table, without requiring other complex decision and selection logic. The use state a corresponds to the antennas 1 and 2, and illustrates that the interference degree between the antennas 1 and 2 in the use state a is minimum, and here, it is not necessary to further list other non-optimal antenna combinations in the interference situation. Similarly, the usage state B corresponds to the antennas 1, 2, and 4, and it is explained that the interference between the antennas 1, 2, and 4 is minimized in the usage state B.

TABLE 2

Taking the use shown in (a-1) of fig. 5 as an example, when the mobile phone processor learns from the sensor that the mobile phone is held by the user according to the angle shown in (a-1) of fig. 5, the processor searches the above table 2, determines that the use state is the use state a, and further determines that the antenna 1 and the antenna 2 corresponding to the use state a are used as target antennas for transmitting or receiving data. The two antennas are used for processing data of the same or different modes.

S403, the device sends or receives data through at least two target antennae. Specifically, the device receives or transmits data of a plurality of different communication systems through at least two target antennas respectively. For example, the at least two target antennas include an antenna 1 and an antenna 2, the antenna 1 is used for transmitting or receiving data of a first communication system, and the antenna 2 is used for transmitting or receiving data of a second communication system. The first communication system and the second communication system 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, S403 controls at least two target antennas to transmit or receive data by the processor 110 shown in fig. 2.

According to the antenna switching method provided by the embodiment of the application, the equipment acquires the using state of the equipment, at least two target antennas are determined among a plurality of candidate antennas of the equipment according to the using state, and data are sent or received through the at least two target antennas. Wherein, because the usage state represents the relative relation between the user and the device in space, when the user and the device have different relative relations in space, the influence degree of the user in the near field region of the antenna on the antenna of the device may be different, and further the influence of the user on the interference degree between the antennas of the device may be different. In the embodiment of the application, the influence of the user on the equipment antenna is fully considered, and then the plurality of antennas for transmitting or receiving data are selected according to the influence degree of the user on the equipment antenna, so that the interference degree among the selected plurality of antennas is smaller.

The schemes of embodiments of the present application are set forth below in connection with specific examples to facilitate further understanding by the reader. Firstly, taking an example that the antenna switching method of the embodiment of the present application is applied to a carrier aggregation scenario, that is, a mobile phone selects a plurality of antennas for receiving and transmitting signals of a certain communication system. Referring to fig. 7, it is assumed that the handset includes a multi-system common control center, 5 antennas of system a, that is, antenna 1, antenna 2, antennas 4 to 6 of system a as shown in fig. 7, and antenna 3 of GPS as shown in fig. 7. The antenna 1, the antenna 4 and the antenna 5 can transmit and receive signals with the frequency range in the band42, the antenna 2 and the antenna 6 can transmit and receive signals with the frequency range in the band1, and the antenna 3 can receive signals with the frequency range of 1575 MHz. The multi-system public control center is used as a functional module arranged on the mobile phone and can be used for controlling the switching antenna, and specifically comprises a processor 110 and also further comprises other necessary components. Or a multisystem common control center may exist as part of processor 110, and in particular may be hardware within processor 110 or software modules running on processor 110. In one example, the multisystem common control center is identical to the processor 110.

When the mobile phone performs data transmission, multiple carriers can be aggregated through an in-band (inter) carrier aggregation technology, so as to obtain a larger transmission bandwidth. Here, the polymerization (band) band1 and band42 are exemplified. band1:1920-1980MHz, band42:3400MHz-3600MHz. If there are two or more transmitting antennas, such as a first antenna and a second antenna, the frequency of the transmitting signal of the first antenna falls into band1, and the frequency of the transmitting signal of the second antenna falls into band42, the transmitting signal of the first antenna and the transmitting signal of the second antenna may generate intermodulation, and the frequency range of the intermodulation signal is between 1420 MHz and 1680 MHz. Assuming that the GPS has a receiving frequency of 1575MHz, the intermodulation signal may fall into the receiving antenna, causing intermodulation interference to the receiving antenna.

In order to reduce the influence of the intermodulation interference, the embodiment of the application provides an antenna switching scheme, when a mobile phone has data (such as Uplink (UL) data) to transmit, the mobile phone obtains the current use state of the mobile phone through a sensor, and can know the isolation between every two antennas meeting the current carrier aggregation requirement according to the corresponding relation between each use state preconfigured in the mobile phone and the isolation between the antennas, such as according to table 1. Taking the aggregation band1 and the band42 as examples, two antennas meeting the current carrier aggregation requirement comprise an antenna capable of receiving and transmitting the band42 signal and an antenna capable of receiving and transmitting the band1 signal. Specifically, for example, the mobile phone detects that the mobile phone is currently in a certain use state, and determines that band1 and band42 need to be aggregated according to the current communication requirement, that is, determines that two antennas meeting the current carrier aggregation requirement include antenna 1 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 as shown in fig. 7. Then, the mobile phone determines, according to the table 1, that in the use state, the isolation between every two antennas meeting the current carrier aggregation requirement is as follows: the isolation between antenna 1 and antenna 2 is 15, the isolation between antenna 1 and antenna 6 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 6 is 25. Furthermore, the mobile phone can select two antennas with larger isolation as antennas used in carrier aggregation according to the isolation between every two antennas meeting the current carrier aggregation requirement. In this way, the possibility of intermodulation generated by the two antennas of the selected system a is reduced, and further, the interference of the intermodulation signal to the GPS antenna 3 shown in fig. 7 is reduced.

As a possible implementation manner, considering that the antennas actually used by the mobile phone may be different under different carrier aggregation requirements, the mapping table may further indicate a group of antennas corresponding to each of the multiple usage states under different CA requirements. For example, for a certain usage state, the correspondence table indicates that when the band1 and the band42 need to be aggregated, the usage state corresponds to the antenna group 1, and when the band1 and the band2 need to be aggregated, the usage state corresponds to the antenna group 2. That is, the above correspondence table may also be embodied as the following table 3:

TABLE 3 Table 3

In combination with the specific example, the mobile detects that the current usage state is usage state a, and the current carrier aggregation requirements are aggregation band1 and band42. Then, the mobile phone searches the corresponding table 3 according to the usage state a and the current carrier aggregation requirement, and can learn that a group of antennas corresponding to the usage state a is the antenna group 1 when the band1 and the band42 need to be aggregated. Subsequently, the mobile phone is switched to the antenna group 1 through the multi-system public control center, and the mobile phone can transmit data through a plurality of antennas of the antenna group 1. Let it be assumed that antenna group 1 comprises antenna 1, antenna 2. The mobile phone implements carrier aggregation through the antenna 1 and the antenna 2, as described above, in general, the isolation between the antenna 1 and the antenna 2 selected by the mobile phone is relatively large, so that when both the antenna 1 and the antenna 2 are used for transmitting signals, the transmitted signal of the antenna 1 and the transmitted signal of the antenna 2 are not easy to generate intermodulation signals, and intermodulation interference of the intermodulation signals to the GPS antenna 3 as shown in fig. 7 is reduced. When one of the antennas 1 and2 is used to transmit a signal and the other is used to receive a signal, such as the antenna 1 is used to transmit a signal and the antenna 2 is used to receive a signal, harmonic interference of the antenna 2 by harmonics generated by the antenna 1 is small because the isolation between the antenna 1 and the antenna 2 is large.

In other embodiments, taking the application of the antenna switching method in the embodiment of the present application in a heterogeneous system multi-connection scenario as an example, that is, the mobile phone works in two or more communication systems, and selects multiple antennas for receiving and transmitting signals in the two or more communication systems.

As a possible implementation manner, considering that when the mobile phone works under different communication systems, the antennas actually used by the mobile phone may be different, the correspondence table may further indicate a group of antennas corresponding to each of the multiple usage states under different communication systems. For example, for a certain usage state, the correspondence table indicates that the usage state corresponds to antenna group 1 when operation in LTE and NR systems is required, and that the usage state corresponds to antenna group 2 when operation in LTE and WCDMA is required. That is, the above correspondence table may also be embodied as the following table 4:

TABLE 4 Table 4

In combination with a specific example, the mobile phone determines that the current use state is the use state a according to the sensing data obtained by the sensor, and the mobile phone determines that the current communication requirement is working in LTE and NR modes. Then, the mobile phone searches the corresponding table 4 according to the usage state a and the current communication requirement, and can know that a group of antennas corresponding to the usage state a is the antenna group 1 when the mobile phone needs to work in LTE and NR. Subsequently, the mobile phone may transmit data through the plurality of antennas of the antenna group 1. Let it be assumed that antenna group 1 comprises antenna 1, antenna 2. The mobile phone receives and transmits LTE signals through the antenna 1 and receives and transmits NR signals through the antenna 2, as described above, since the isolation between the antenna 1 and the antenna 2 selected by the mobile phone is generally large, the intermodulation signals are not easily generated by the transmission signals of the antenna 1 and the transmission signals of the antenna 2, and thus, the intermodulation interference of the intermodulation signals to other antennas is reduced. When the isolation between the antenna 1 and the antenna 2 is large, the transmission signal of the antenna 1 is less likely to cause harmonic interference to the antenna 2, and the transmission signal of the antenna 2 is less likely to cause harmonic interference to the antenna 1.

It will be appreciated that, in order to implement the above-mentioned functions, the apparatus in the embodiments of the present application includes corresponding hardware structures and/or software modules that perform the respective functions.
