Description

Antenna switching method and device

Technical Field

The present application 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 plurality of antennas may be disposed in a terminal. For one antenna, it is likely that one antenna can be used for transceiving data of different systems. When a plurality of antennas operate simultaneously, interference may occur between the plurality of antennas. 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 modulate with each other, thereby generating a new frequency signal output. If the new frequency falls well within the operating bandwidth of the receiver, interference may be caused to the received signal of the receiver. The interference caused to the receiver by the signals generated by the inter-modulation of multiple signals is called intermodulation interference. Taking fig. 1 as an example, if a signal is transmitted at 1940MHz through one antenna and at 1980MHz through another antenna, the two transmitted signals may generate a 1900MHz signal, which happens to fall into the receiving band of the left-side receiver, and therefore, may cause intermodulation interference to the normal reception of the receiver. In another scenario, harmonics (such as the first harmonic, the 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 harmonics of the transmitted signal is called harmonic interference.

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

Disclosure of Invention

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

In a first aspect, an embodiment of the present application provides an antenna switching method, which is applied to a device or a component in the device. The method comprises the following steps: the method includes acquiring a use state of the device, and determining at least two target antennas among a plurality of candidate antennas of the device according to the use state. Thereafter, data is transmitted or received through at least two target antennas. Wherein the usage status represents a relative relationship in space between the user and the device. Thus, when the user and the device have different relative relationships in space, the degree of influence of the user in the antenna near-field area on the device antenna may be different, and further the degree of influence of the user on the interference between the device antennas 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 used for sending or receiving data are selected according to the influence degree of the user on the equipment antenna, so that the interference degree among the plurality of selected antennas is small.

In one possible design, determining at least two target antennas among a plurality of candidate antennas of a device according to a usage status includes: according to the using state, searching a corresponding table 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 use state in the plurality of use 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 without executing other complex judgment logics, and the implementation complexity of the device is reduced.

In one possible design, obtaining the usage status of the device includes: and acquiring sensing data through one or more sensors, and acquiring the use state of the equipment according to the sensing data.

That is, at least two target antennas selected by the device according to the current use state may be antennas for receiving or transmitting signals of the same communication system. For example, two target antennas are selected, and both the two 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 systems. For example, two target antennas are selected, wherein one target antenna is used for receiving or transmitting 4G signals, and the other target antenna is used 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 or receiving data. When the first antenna is used for transmitting data and the second antenna is used for transmitting data, the transmission signal of the first antenna and the transmission signal of the second antenna may generate an intermodulation signal, which may affect the 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, harmonic interference may be generated on the second antenna or other receiving antennas by the first harmonic, the second harmonic, and the like generated by the transmission signal of the first antenna. By adopting the antenna switching method of the embodiment of the application, 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.

For example, when a photo is taken, 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 and converting into an image visible to naked eyes. The ISP can also carry out algorithm optimization on the focus, the noise point, the brightness and the 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 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 to the photosensitive element. The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into image signal in standard RGB, YUV and other formats. In some embodiments, the handset 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 digital image signals and other digital signals. For example, when the handset 100 is in frequency bin selection, the digital signal processor is used to perform fourier transform or the like on the frequency bin energy.

Video codecs are used to compress or decompress digital video. Handset 100 may support one or more video codecs. Thus, the handset 100 can play or record video in a variety of encoding formats, such as: moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, MPEG4, and the like.

The NPU is a neural-network (NN) computing processor that processes input information quickly by using a biological neural network structure, for example, by using a transfer mode between neurons of a human brain, and can also learn by itself continuously. The NPU can realize applications such as intelligent recognition of the mobile phone 100, for example: image recognition, face recognition, speech recognition, text understanding, and the like.

The methods in the following embodiments can be implemented in the mobile phone 100 having the above hardware structure. It should be noted that the method of the following embodiments may also be applied to an electronic device or a component (e.g., a system-on-a-chip) of an electronic device having a structure similar to that of fig. 2. For example, the present embodiment provides an antenna switching apparatus, which may be a standalone device, located in the mobile phone 100 in fig. 2, and specifically may 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, thereby forming a system, and the apparatus mainly includes the processor 110 shown in fig. 2. The apparatus may further include a communication device (such as the radio frequency module 150, the communication module 160, and the like shown in fig. 2), a storage device (such as the internal memory 121 shown in fig. 2), and the like.

The embodiment of the application provides an antenna switching method, which can be applied to an electronic device or a component (such as a chip system) in the electronic device. The antenna switching method according to the embodiment of the present application is mainly described in detail below by taking an electronic device as a mobile phone as an example, where the device may be the mobile phone 100 or a component therein, 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 using state of the device. As a possible implementation, the sensing data may be detected by one or more sensors, and the usage status of the device may be acquired according to the detected sensing data. The sensor may refer to the previous description, which is not repeated herein, 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 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 between a user using the device and the device, and the spatial relative relationship between the user and the device includes, but is not limited to, a combination of one or more of the following: the relative position relationship of the user and the equipment, the relative speed relationship of the user and the equipment, the relative acceleration relationship of the user and the equipment, and the relative angular speed relationship of the user and the equipment. The relative positional relationship of the user and the device includes, but is not limited to, the distance, angular (i.e., the angle at which the device is held by the user) relationship between the user and the device. Illustratively, the usage state of the device includes, but is not limited to, a combination of one or more of the following: the hand-held device comprises a left hand stationary grip, a right hand stationary grip, a two-hand stationary grip, a horizontal grip, a vertical grip, a left hand grip at a first speed, a right hand grip at a second speed, a two-hand grip at a third speed, a left hand rotation at a first angular speed, a right hand rotation at a second angular speed, a two-hand rotation at a third angular speed, a left hand grip at a first acceleration, a right hand grip at a second acceleration, a two-hand grip at a third acceleration, a palm-to-device contact area and/or contact area when the left hand grip, a palm-to-device contact area and/or contact area when the right hand grip, a palm-to-device contact area and/or contact area when the two hands grip.

As an example, the sensing data may refer to data directly measured 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 the brightness of the ambient light from the ambient light sensor to adjust the brightness of the display of the touch screen 104 or to perform other cell phone functions. For another example, the acceleration sensor can detect the magnitude of the inertial force applied to the mass block in each direction (generally, three axes), and can detect the magnitude and direction of the gravity when the mass block is stationary, and the data of the measured inertial force, the magnitude and direction of the gravity, and the like can be referred to as sensing data of the acceleration sensor. Subsequently, based on the sensing data such as the inertial force 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 deduce 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 of recognizing the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping) and the like.

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

In some embodiments, when a user holds a mobile phone, different antennas on the mobile phone may be shielded due to different contact areas and different contact areas between the palm and the mobile phone when the user holds the mobile phone, so that the radiation intensity of the shielded antennas is affected, and the interference degree between the shielded antennas and other antennas is affected. Taking fig. 5 as an example, as shown in (a) of fig. 5, when a user holds a mobile phone with both hands, the contact area between the palm and the mobile phone is area 1 and area 2, as shown in (b) of fig. 5, when a user holds a mobile phone with one hand (right hand), the contact area between the palm and the mobile phone is area 1, and since the contact area of (a) of fig. 5 is larger than the contact area of (b) of fig. 5, the mobile phone may block more antennas in the usage state shown in (a) of fig. 5 than in the usage state shown in (b) of fig. 5, and the interference degree between the mobile phone antennas may be different in the two usage states. For another example, as shown in fig. 5 (c), when the user holds the mobile phone with both hands, the contact areas between the palm and the mobile phone are areas 3 and4, and areas 3 and4 are closer to the top of the mobile phone than areas 1 and2 shown in fig. 5 (a). If the mobile phone antenna is arranged 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, more antennas can be shielded, or the shielding degree of the antennas is higher, and then the radiation intensity of the shielded antennas is influenced more greatly. Thus, the degree of interference 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 usage state shown in fig. 5 (d), the degree of interference between the antennas of the mobile phone 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 antenna of the mobile phone with respect to the ground plane may be different, which may cause the antenna to have different spatial radiation, such as different radiation intensity, radiation direction, and the like, and thus the degree of interference between the antennas may also be different. As shown in fig. 6 (a-1), the angle at which the handset is held by the user is α, i.e., the angle between the handset and the ground plane is α; then, as shown in fig. 6 (a-1) to fig. 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 usage states of the handset shown in fig. 6 (a-1), (b) and (c-1) of fig. 6, the degree of interference between the antennas of the handset may be different depending on the angle at which the handset is held. Still referring to fig. 5 (d), in the usage 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 approximately horizontally held 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 may be affected by the holding angle.

In some embodiments, when the mobile phone has different distances with respect to the user, the mobile phone antenna and the user may have different distances, so that the users in the near field of the mobile phone antenna may have different influence on the radiation characteristics of the antenna, and thus 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, so that the influence degree of the mobile phone on the radiation characteristics of the antennas may be different, and the interference degree 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 the 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 time period, and thus the degree of interference between the antennas may be different. The above description is only exemplary to give some possible device use states, the device use states may also be other, and the embodiments of the present application are not exhaustive.

As indicated above, the interference level between the antennas of the mobile phone may be different in different usage 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 handset, wherein the degree of interference between the selected plurality of antennas is small. For example, when the sensor detects that the angle at which the mobile phone is held by the user is as shown in (a-1) in fig. 6, (b) in fig. 6, and (c-1) in fig. 6, respectively, the processor in the mobile phone may obtain the angle at which the mobile phone is held 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 in (a-1) in fig. 6, where in this usage state, the degree of interference between the antennas in the antenna group 1 is small. Similarly, when the handset is held by the user at an angle shown in fig. 6 (b), the processor selects the antenna group 2 as an antenna for transmitting or receiving data, and when the handset is held by the user at an angle shown in fig. 6 (c-1), the processor selects the antenna group 3 as an antenna for transmitting or receiving data.

As a possible implementation manner, the interference degree between every two antennas in the multiple antennas of the mobile phone in each use state can be obtained through a pre-test. Each use state and the degree of interference between each two of the 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 the transmit antenna to the power that is coupled (leaked) to the receive antenna. Typically, the power that the transmit power leaks to the receive antenna is less than the transmit power, and therefore the value of the isolation is typically greater than 1. Generally, a greater value of isolation between two antennas indicates a lesser degree of interference between the two antennas.

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

TABLE 1

As can be seen from table 1, in general, the isolation between each two antennas of the multiple antennas of the device is different under different use conditions. 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, there may be two antennas with the same isolation in different use states. 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, system a is a 4G system, system B is a 5G system, system a uses a corresponding first antenna to transmit, system B uses a corresponding second antenna to receive, and the first antenna and the second antenna may be antennas in 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 represented by a correlation coefficient between the two antennas. The correlation coefficient can be described in detail in the prior art. Alternatively, other parameters may be used. The embodiment of the present application does not limit what parameters are specifically used to represent the interference level between the antennas.

Based on each usage status and the interference level between every two antennas in the multiple antennas of the corresponding mobile phone, for example, based on table 1 above, each usage status may correspond to a group of antennas, where the group of antennas includes N antennas with the minimum interference level therebetween, and N is a positive integer greater than or equal to 2. Taking the interference degree expressed by isolation as an example, assuming that 5 antennas, i.e. antennas 1-5, are provided on the mobile phone, in the use state a, the available combinations of the antennas are 10, wherein the isolation of each antenna combination in the 5 antenna combinations is as follows: the isolation between the antenna 1 and the antenna 2 is 8, the isolation between the antenna 1 and the antenna 5 is 12, the isolation between the antenna 2 and the antenna 5 is 15, the isolation between the antenna 2 and the antenna 3 is 10, and the isolation between the antenna 3 and the antenna 4 is 20. The isolation of the other 5 antenna combinations is not listed. In some embodiments, the set of antennas corresponding to each use state includes two antennas, and since the isolation between the antenna 3 and the antenna 4 is the largest, the set of antennas corresponding to the use state a is the antenna 3 and the antenna 4. In other embodiments, the set of antennas for each use state includes more than two antennas. That is, in a certain use state, the device may further 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 transmit and receive signals. For example, in a certain usage state, the device selects antennas 1 to 4 as a group of antennas corresponding to the usage state. The antennas 1 to 4 are all used for processing 5G signals, wherein a signal band of the antenna 1 and a signal band of the 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, assuming that 4 antennas are selected as the antennas to be used by the device in the use state a, among the antennas 1 to 5, since the isolation between the antennas 3 and4 and the isolation between the antennas 2 and 5 have the largest value among the plurality of isolation, the group of antennas corresponding to the use state a may be the antennas 2, 5, 3 and 4. Subsequently, when the mobile phone detects that the mobile phone is in a certain use state, a group of antennas corresponding to the use state and having the minimum mutual interference degree (for example, the maximum isolation degree) are used as antennas for transmitting or receiving data. Specifically, the mobile phone selects an antenna according to the use state, and can be implemented as follows: the mobile phone looks up 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 sending or receiving data.

The at least two target antennas selected by the mobile phone comprise a first antenna and a second antenna, wherein the first antenna is used for sending data, and the second antenna is used for sending or receiving data. That is, at least one antenna for transmitting data is included in the at least two antennas. 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 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, harmonic interference may be generated on the second antenna or other receiving antennas by the first harmonic, the second harmonic, and the like generated by the transmission signal of the first antenna. Based on the above embodiments of the present application, at least two target antennas selected by the device are a group of antennas with the minimum mutual interference degree, so that no matter the first antenna and the second antenna (multiple antennas) are used together as a transmitting antenna to generate intermodulation interference, or only the first antenna is used as a transmitting antenna to generate harmonic interference, the generated interference degree can be guaranteed to be minimum.

It should be further noted that the first antenna and the second antenna may be respectively used for receiving or transmitting data of the same or different communication systems. For example, the at least two target antennas include an antenna 1 of a system a and an antenna 2 of a system B in table 1, where the system a is a system of an LTE communication system, the system B is a system of a WCDMA communication system, the antenna 1 is used to receive or transmit data of the LTE communication system, and the antenna 2 is used to receive or transmit data of the WCDMA communication system. For another example, the at least two target antennas include antenna 1 and antenna 2 of system a in table 1, where antenna 1 and antenna 2 are used for receiving or transmitting data of 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 searched corresponding table is used for indicating a group of antennas corresponding to each use state in a plurality of use states, and each group of antennas comprises two or more antennas. For a certain use state, the antenna group corresponding to the use state is the antenna group with the minimum mutual interference degree in the use state. As shown in table 2 below, in an exemplary implementation of the mapping table, the processor 110 directly obtains the antenna combination corresponding to the optimal interference condition of the use state by looking up the table without other complex judging and selecting logic. The use state a corresponds to the antenna 1 and the antenna 2, which means that the interference degree between the antenna 1 and the antenna 2 is minimum in the use state a, and here, it is not necessary to further list other antenna combinations with non-optimal interference conditions. Similarly, the use state B corresponds to the antenna 1, the antenna 2, and the antenna 4, and it is described that the degree of mutual interference among the antenna 1, the antenna 2, and the antenna 4 is minimum in the use state B.

TABLE 2

Taking the use shown in (a-1) in fig. 5 as an example, when the processor of the mobile phone learns from the sensor that the mobile phone is held by the user at the angle shown in (a-1) in fig. 5, the processor looks up the 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 to process data of the same or different systems.

And S403, the equipment transmits or receives data through at least two target antennas. 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, where the antenna 1 is used for sending or receiving data of a first communication system, and the antenna 2 is used for sending or receiving data of a second communication system. The first communication scheme and the second communication scheme may be the same or different. Specifically, the processor 110 may control the antennas 1 and2 to perform data transmission or reception.

As a possible implementation manner, 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 device acquires the use state of the device, determines at least two target antennas from a plurality of candidate antennas of the device according to the use state, and sends or receives data through the at least two target antennas. Since the usage state represents the spatial relative relationship between the user and the device, when the user and the device have different spatial relative relationships, the degree of influence of the user in the antenna near-field area on the device antenna may be different, and further the degree of influence of the user on the interference between the device antennas 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 used for sending or receiving data are selected according to the influence degree of the user on the equipment antenna, so that the interference degree among the plurality of selected antennas is small.

Aspects of the embodiments of the present application are described below in conjunction with specific examples to facilitate further understanding by the reader. First, 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 multiple antennas for receiving and transmitting signals of a communication system in 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, i.e., antenna 1, antenna 2, antenna 4 to antenna 6 of system a shown in fig. 7, and antenna 3 of GPS shown in fig. 7. The antenna 1, the antenna 4, and the antenna 5 may transmit and receive signals with a frequency range (band 42) band42, the antenna 2 and the antenna 6 may transmit and receive signals with a frequency range (band 1) band1, and the antenna 3 may receive signals of 1575 MHz. The multisystem common control center is used as a functional module arranged on the mobile phone, and can be used for controlling the switching of the antennas, and specifically comprises the processor 110, and can further comprise other necessary components. Or a multi-system common control center may exist as part of the processor 110, and may be embodied as hardware within the processor 110 or as a software module running on the processor 110. In one example, a multi-system common control center is equivalent to the processor 110.

When the mobile phone performs data transmission, multiple carriers can be aggregated by an intra-band (inter) carrier aggregation technology, so as to obtain a larger transmission bandwidth. Here, the aggregation (band) bands 1 and42 are described as examples. band 1: 1920-1980MHz, band 42: 3400MHz-3600 MHz. 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-. Assuming that the receiving frequency of the GPS is 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, an embodiment of the present application provides an antenna switching scheme, where when a mobile phone has data (e.g., Uplink (UL) data) transmission, the mobile phone obtains a current use state of the mobile phone through a sensor, and obtains an isolation between every two antennas that meets a current carrier aggregation requirement according to a correspondence between each use state and an isolation between the antennas, which are preconfigured in the mobile phone, for example, according to table 1. Taking aggregation band1 and band42 as examples, two antennas meeting the current carrier aggregation requirement include one antenna capable of transceiving band42 signals and one antenna capable of transceiving band1 signals. Specifically, for example, the mobile phone detects that the mobile phone is currently in a certain use state, and determines to aggregate bands 1 and42 according to the current communication requirement, that is, it is determined that two antennas meeting the current carrier aggregation requirement include antennas 1 and2, antennas 1 and 6, antennas 4 and2, antennas 4 and 6, antennas 5 and2, and antennas 5 and 6 as shown in fig. 7. Then, the handset determines, according to table 1 for example, that in the use state, the isolation between each two antennas which meet 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 the antennas used for carrier aggregation according to the isolation between every two antennas meeting the current carrier aggregation requirement. In this way, the possibility of generating intermodulation between 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, in consideration of that 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 use state of the multiple use states respectively under different CA requirements. For example, for a certain usage state, the correspondence table indicates that the usage state corresponds to antenna group 1 when aggregation bands 1 and42 are required, and corresponds to antenna group 2 when aggregation bands 1 and2 are required. That is, the above correspondence table may also be embodied as the following table 3:

TABLE 3

In connection with a specific example, the handset detects that the current usage state is the usage state a, and the current carrier aggregation requirements are aggregation band1 and band 42. Then, the handset searches the corresponding table 3 according to the use state a and the current carrier aggregation requirement, and it can be known that when the aggregation bands 1 and42 are required, a group of antennas corresponding to the use state a is the antenna group 1. Subsequently, the mobile phone is switched to the antenna group 1 through the multi-system common control center, and the mobile phone can transmit data through the multiple antennas of the antenna group 1. It is assumed that antenna group 1 comprises antenna 1 and antenna 2. The mobile phone implements carrier aggregation through the antenna 1 and the antenna 2, as described above, generally, the isolation between the antenna 1 and the antenna 2 selected by the mobile phone is large, so when both the antenna 1 and the antenna 2 are used for transmitting signals, the transmission signal of the antenna 1 and the transmission signal of the antenna 2 are not easy to generate an intermodulation signal, and thus, the intermodulation interference of the intermodulation signal to the GPS antenna 3 shown in fig. 7 is reduced. When one of the antennas 1 and2 is used for transmitting signals and the other is used for receiving signals, for example, the antenna 1 is used for transmitting signals and the antenna 2 is used for receiving signals, the harmonic generated by the antenna 1 has less harmonic interference with the antenna 2 because the isolation between the antenna 1 and the antenna 2 is larger.

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

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

TABLE 4

In combination with a specific example, the mobile phone determines that the current use state is the use state a through the sensing data acquired by the sensor, and determines that the current communication requirement is working in LTE and NR modes. Then, the mobile phone searches the correspondence table 4 according to the use state a and the current communication requirement, and can know that when the mobile phone needs to work in LTE and NR, one group of antennas corresponding to the use state a is the antenna group 1. Subsequently, the handset can transmit data through multiple antennas of the antenna group 1. It is assumed that antenna group 1 comprises antenna 1 and antenna 2. As described above, the isolation between the antenna 1 and the antenna 2 selected by the mobile phone is usually large, so that the sending signal of the antenna 1 and the sending signal of the antenna 2 are not easy to generate an intermodulation signal, and the intermodulation interference of the intermodulation signal to other antennas is also reduced. Further, 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 with the antenna 2, and the transmission signal of the antenna 2 is less likely to cause harmonic interference with the antenna 1.
