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 photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor.

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 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. 1. For example, the present embodiment provides an antenna switching apparatus, which may be a standalone device, located in the mobile phone 100 in fig. 1, 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. 1. 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. 1), a storage device (such as the internal memory 121 shown in fig. 1), and the like.

The communication module 160 and the rf module 150 include rf components for processing radio frequency (radio frequency) signals received from the antenna and converting to a lower intermediate frequency. As shown in fig. 2, as one possible implementation, the radio frequency component includes a Radio Frequency Integrated Circuit (RFIC), a Power Amplifier (PA), a Low Noise Amplifier (LNA), a filter, a switch, and a duplexer. The RFIC may include a modem to perform modulation and demodulation, i.e., up-mixing or down-mixing, of signals, among others. The change-over switch is used for realizing the switch of the receiving and the transmitting of the radio frequency signal or the switch among different frequency bands. The duplexer is used for isolating the transmitting signal from the receiving signal and ensuring that the receiving signal and the transmitting signal can work normally at the same time.

Referring to fig. 2, the radio frequency components are connected to a multi-port multiple output (XPXT) switch. An XPXT switch for switching the antenna switch under control of the processor. For transmitting signals in cellular communication, cellular signals are transmitted through an antenna after passing through an RFIC, a PA, a filter, a switch and a duplexer in a radio frequency component. For the received signal in cellular communication, the cellular signal is received by an antenna, and then passes through a duplexer, a switch, a filter and an LNA in a radio frequency part, and then reaches a modem for demodulation. As a possible implementation, referring to fig. 3, a plurality of antennas, such as the antenna 2 and the antenna 3, may also be connected through a power Divider (DIP). The power divider is connected with the multi-port multi-output switch. The multi-port multi-output switch may be connected to a component having a processing function, for example, to the processor 110 as shown in fig. 1, so that the processor 110 can control the switching of the antenna by controlling the multi-port multi-output switch. The power divider and multi-port multi-output switch of fig. 3 are located outside the rf component of fig. 2; alternatively, the power divider and the multi-port multi-output switch may also be located in the radio frequency component in fig. 2, which is not limited in this embodiment.

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 S201 to S203.

S201, the equipment acquires priorities of a plurality of communication systems of the equipment and communication parameters respectively corresponding to a plurality of candidate antennas of the equipment. Wherein the priority may be predefined in advance. As a possible implementation manner, the signal strength corresponding to each communication system in a historical time period may be counted to determine the priority of the communication system. The higher the priority is corresponding to the communication system with high signal strength, the lower the priority is corresponding to the communication system with low signal strength. The signal strength may be characterized by a number of different parameters. For example, the signal strength is characterized by Reference Signal Receiving Quality (RSRQ). The signal strength is characterized by Reference Signal Receiving Power (RSRP). Alternatively, the signal strength is characterized by other parameters. In a possible implementation manner, power consumption corresponding to each communication system in a historical period may be counted. The priority is higher corresponding to the communication system with lower power consumption, and the priority is lower corresponding to the communication system with higher power consumption. Of course, the priorities of different communication systems may also be characterized or defined by other parameters or manners. The embodiment of the present application does not limit this.

The communication parameters of the candidate antenna include, but are not limited to, a first communication parameter and a second communication parameter. The first communication parameter includes a transmission margin, and the second communication parameter may include, for example, a combination of one or more of the following: transmit signal strength, receive signal strength, throughput, power consumption, or traffic priority. The transmission margin of the device, also called power transmission margin, refers to the difference between the upper limit of the transmission power of the device and the current actual transmission power. The larger the transmission margin is, the larger the transmission power can be increased by the device based on the current transmission power, and the larger the power potential of the device is, that is, the larger the potentially transmittable power is. The smaller the transmission margin is, the smaller the transmission power can be increased by the device based on the current transmission power. The transmission margin can be used to evaluate the coverage of the cell, and theoretically, the better the coverage, the smaller the transmission power, and the larger the transmission margin. Taking a mobile phone as an example, the sending signal strength refers to the uplink signal strength, and the receiving signal strength refers to the downlink signal strength. It should be noted that, in the embodiments of the present application, only some communication parameters affecting the antenna performance are listed, and the communication parameters for antenna switching may also include other similar parameters, and the embodiments of the present application are not exhaustive here.

Taking the device as a mobile phone as an example, the plurality of communication systems in the embodiment of the present application may be communication systems of the mobile phone, such as 2G/3G/4G/5G shown in fig. 1, or may also be communication systems of RT/WLAN/GNSS/NFC/IR/FM shown in fig. 1.

The candidate antennas refer to antennas corresponding to a plurality of communication systems. In the embodiment of the present application, an antenna corresponding to a certain communication system refers to an antenna that can be used for receiving or sending a signal of the communication system. For example, an antenna corresponding to LTE (which may be referred to as an LTE antenna for short) refers to an antenna that can be used to receive or transmit LTE signals. For example, a certain antenna can be used for receiving or transmitting LTE signals and NR signals, and the antenna may be referred to as an LTE antenna and may also be referred to as an NR antenna. Taking fig. 1 as an example, the candidate antenna may be an antenna in the antenna a shown in fig. 1, or may be an antenna in the antenna B shown in fig. 1.

The following mainly takes a scenario in which a mobile phone operates in two communication systems, LTE and NR, as an example to describe the technical solution of the embodiment of the present application. When the mobile phone needs to work under two communication systems of LTE and NR, the mobile phone obtains the priority of the two communication systems of LTE and NR according to predefined configuration, and obtains the communication parameters of each LTE antenna and each NR antenna respectively.

S202, the equipment determines at least one target antenna used for sending or receiving information of a plurality of communication systems in the plurality of candidate antennas according to the priority and the communication parameters respectively corresponding to the plurality of candidate antennas. Specifically, S202 may be implemented as: the method comprises the steps of obtaining scores of one or more communication systems corresponding to each candidate antenna according to second communication parameters corresponding to the candidate antennas respectively, determining antenna scores corresponding to each candidate antenna according to the scores of the one or more communication systems of each candidate antenna, and/or determining scores of one or more communication systems corresponding to each antenna, and selecting at least one target antenna of which the antenna scores or the communication system scores meet preset conditions from the candidate antennas according to priorities of the multiple communication systems and first communication parameters corresponding to the candidate antennas respectively.

Wherein the scoring rules may be predefined in advance and preconfigured in the device. In this way, the device may obtain the score of one or more communication systems of the antenna by querying the score rule. As a possible implementation manner, for a certain communication system of the antenna, a value interval is set for a second communication parameter corresponding to the communication system in which the antenna operates, and when the value of the second communication parameter falls within a certain value interval, the score for the second communication parameter is the score corresponding to the value interval. The device may obtain the score of the communication system according to the score of the second communication parameters in the communication system. The communication system score may be, for example, but not limited to, the sum of weighted summation results of scores for a plurality of second communication parameters, or the average of the weighted summation results, or other algorithms. Illustratively, the scoring rule is as shown in table 1, when the value of the LTE signal strength of a certain candidate antenna falls within 80-90, the device learns that the score corresponding to the LTE transmission signal strength of the antenna is 70 scores by querying the scoring rule such as shown in table 1, and similarly, the device may learn scores for other types of second communication parameters by querying table 1. The device may evaluate a weighted sum of a plurality of scores for the plurality of second communication parameters to determine an LTE score for the candidate antenna. Based on similar principles, the device finds the NR score for the candidate antenna. On this basis, the device calculates the antenna score of the candidate antenna according to the LTE score and the NR score of the candidate antenna, and as a possible implementation manner, the antenna score may be a result of weighted summation of scores of respective communication systems when the antenna operates in one or more communication systems, or a final antenna score is obtained by performing other algorithms on the scores of the respective communication systems. For example, antenna a can be used to receive or transmit LTE and NR signals, and the score for antenna a can be the weighted sum of the LTE and NR scores when antenna a operates in LTE and NR, respectively.

TABLE 1

In the score rule shown in table 1, the relationship between a certain second communication parameter and the score for the second communication parameter may be such that the score is higher as the value of the second communication parameter is larger. For example, the higher the transmission signal strength is, the higher the score for the second communication parameter, transmission signal strength is; the greater the received signal strength, the higher the score for the second communication parameter, received signal strength; the greater the throughput, the higher the score for throughput; the higher the traffic priority, the higher the score for the traffic priority. Of course, the relationship between a certain second communication parameter and the score for the second communication parameter may be that the score is higher when the value of the second communication parameter is smaller, for example, the score for power consumption is higher when the power consumption is smaller.

By adopting the above technical scheme of scoring the antenna, since the antenna score is obtained by using the second communication parameter which affects the antenna performance, the antenna with high score generally has better antenna performance. The antenna score can be used as one of the bases for subsequent antenna switching, so that the probability that the selected antenna is a high-performance antenna can be improved.

In this embodiment of the application, as in the above technical solution, on the basis of obtaining antenna scores of multiple candidate antennas corresponding to multiple communication systems and one or more communication system scores of each candidate antenna, a candidate antenna meeting a preset condition needs to be further selected as a target antenna for device communication. Specifically, when the priority conditions of the multiple communication systems are different, the specific target antenna selection modes may be different. As follows, taking the device needs to process the first communication system signal and the second communication system signal, that is, the multiple communication systems include the first communication system and the second communication system as an example, the manner of selecting the target antenna under different priorities is described in several cases. The device needs to select an antenna capable of receiving or transmitting a first communication system signal and an antenna capable of receiving or transmitting a second communication system signal. The antenna capable of receiving or transmitting the first communication system signal and the antenna capable of receiving or transmitting the second communication system signal may be the same antenna or different antennas.

Case 1: the priority of the first communication system is different from that of the second communication system. In this case, the following sub-cases can be divided. Here, taking the case where the priority of the first communication scheme is higher than that of the second communication scheme as an example, the description is unified here.

As a possible implementation manner, the device determines which communication system is preferentially selected by determining first parameter values respectively corresponding to the antennas of the high-priority communication system.

Sub-case 1: the priority of the first communication system is higher than that of the second communication system, and for at least one antenna of the first communication system in the candidate antennas, a first communication parameter of the first communication system is larger than or equal to a first threshold.

In this case, it is described that the antenna of the first communication system has not only a high priority, but also the coverage of the cell of the first communication system is generally better, and in this case, it is considered that the main performance of communication does not depend on the performance of the first communication system, but may depend on the performance of the second communication system, which may have a poor coverage. Therefore, the target antenna for processing the second communication system information is preferentially selected, so that the communication performance of the equipment is improved. Specifically, preferentially selecting a target antenna for receiving or sending the second communication system information may specifically be implemented as follows: and selecting one or more antennas with the highest second communication mode score from the antennas of the second communication mode of the candidate antennas as target antennas for receiving or sending the second communication mode information.

On the basis of preferentially selecting the target antenna of the second communication system, selecting the target antenna for receiving or sending the information of the first communication system, which can be specifically realized as follows: selecting one or more antennas with the highest first communication score from the antennas of the candidate antennas in the first communication system as target antennas for receiving or sending information of the first communication system; or, for the antennas of the first communication system except the target antenna for receiving or sending the second communication system information (i.e. the target antenna of the second communication system) in the multiple candidate antennas, selecting one or more antennas with the highest first communication system score as the target antennas for receiving or sending the first communication system information; or selecting a target antenna for receiving or sending the second communication system information as the target antenna for receiving or sending the first communication system information.

In addition, because the influence of the performance of the first communication system on the communication performance of the whole equipment is possibly small, the equipment can also adopt a random mode to select the target antenna of the first communication system on the basis of preferentially selecting the target antenna of the second communication system.

Wherein the first communication parameter comprises a transmission margin.

Illustratively, the first communication system is NR, the second communication system is LTE, and it is assumed that the device determines that the priority of NR is higher than that of LTE according to a predefined configuration. The device is provided with 3 antennas as shown in fig. 3. Among them, the antenna 1 can be used for receiving or transmitting NR signals and LTE signals, the antenna 2 can be used for receiving or transmitting NR signals, and the antenna 3 can be used for receiving or transmitting LTE signals. The device acquires that the NR transmission margin of the antenna 1 and the NR transmission margin of the antenna 2 are both greater than or equal to a first threshold by acquiring communication parameters of the antennas 1 to 3, and preferentially selects a target antenna for processing an LTE signal so as to improve the communication performance of the device. Illustratively, the device selects one or more antennas with the highest LTE score from the antennas 1 to 3 as target antennas for processing the LTE second communication system information. Wherein the number of selected LTE antennas may be determined according to the communication requirements of the device. In some scenarios, for example, when the requirement on transmission power is not high, the device selects one antenna with the highest LTE score to process the LTE signal, and in other scenarios, for example, when LTE diversity is required, the device selects two antennas with the highest LTE score as LTE target antennas, that is, target antennas for processing the LTE signal.

On the basis of preferentially selecting the LTE target antenna, the device may select the NR antenna in one of the following manners. Still referring to fig. 3, assuming that the device preferentially selects antenna 1 as the LTE target antenna, in one example, the device selects one or more antennas with the highest NR score among NR antennas other than antenna 1 (i.e., antenna 2) as target antennas for receiving or transmitting NR information. As such, the device may process LTE information and NR information through different antennas. Or, in another example, when the device selects the NR target antenna, the selected LTE target antenna is not excluded, that is, the device selects one or more antennas with the highest NR score among all NR antennas (antenna 1 and antenna 2) as the target antennas for receiving or transmitting NR information. In this case, the device may process the LTE information and the NR information through different or the same antenna. Or, in another example, the antenna 1 shown in fig. 3 can also be used to process NR signals, the device may directly select the antenna 1 as the NR target antenna. As such, the device may process LTE signals and NR signals through the same antenna. Alternatively, the NR antennas may be selected in a random manner, i.e., the score of the selected NR antennas is not limited.

Of course, the device may also combine the above several methods for selecting an NR antenna, for example, if the antenna 1 shown in fig. 3 can also be used to process an NR signal, the device selects the antenna 1 as an NR target antenna, and if the device needs two NR antennas for current communication, the device may continue to select another NR antenna with a higher NR score as an NR target antenna, for example, the antenna 2 shown in fig. 3.

Sub-case 2: the priority of the first communication system is higher than that of the second communication system, and for at least one antenna of the first communication system, a first communication parameter of the first communication system is smaller than a first threshold.

Under such a situation, the coverage of the high-priority first communication system cell is poor, and the influence of the performance of the first communication system on the communication performance of the equipment is considered to be larger, so that the target antenna of the first communication system is preferentially selected, so that the communication performance of the whole equipment is improved. Preferentially selecting a target antenna of a first communication system, which can be specifically realized as follows: and selecting one or more antennas with the highest first communication system score from the antennas of the first communication system of the candidate antennas as target antennas for receiving or sending the first communication system information. See above for a detailed description of this mode. On the basis of preferentially selecting the target antenna of the first communication system, selecting the target antenna of the second communication system can be specifically realized as follows: selecting one or more antennas with the highest second communication score from the antennas of the second communication system of the candidate antennas as target antennas for receiving or sending information of the second communication system; or, for the multiple candidate antennas, selecting one or more antennas with the highest second communication system score from the antennas of the second communication system except the target antenna for receiving or sending the first communication system information as the target antenna for receiving or sending the second communication system information; or selecting a target antenna for receiving or sending the first communication system information as a target antenna for receiving or sending the second communication system information. See above for a detailed description of this mode.

As another possible implementation manner, the device not only determines the first communication parameters respectively corresponding to the antennas of the high-priority communication system, but also determines the first communication parameters respectively corresponding to the antennas of the low-priority communication system, so as to determine which communication system is preferentially selected as the target antenna.

Sub-case 3: the priority of the first communication system is higher than that of the second communication system, and for at least one antenna of the first communication system, the first communication parameter of the first communication system is greater than or equal to a first threshold, and for at least one antenna of the second communication system, the first communication parameter of the second communication system is greater than or equal to the first threshold.

Different from the sub-case 1, in the sub-case 1, once the device learns that the coverage condition of the cell of the first communication system is better, the device directly selects the target antenna of the second communication system preferentially, and does not judge whether the coverage of the cell of the second communication system is good. In sub-case 3, when the device learns that the coverage of the first communication system cell with the high priority is better, it needs to acquire whether the coverage of the second communication system cell with the low priority is good, so as to further determine which communication system target antenna is preferentially selected.

As a possible implementation manner, if the coverage of the cell of the second communication scheme with the low priority is also good, the device may preferentially select the target antenna of the high priority communication scheme, that is, preferentially select the target antenna of the first communication scheme. Therefore, the processing efficiency of the high-priority communication system signal, namely the first communication system signal, can be improved. Specifically, preferentially selecting the target antenna of the first communication system with the high priority may be implemented as follows: and selecting one or more antennas with the highest first communication system score from the antennas of the first communication system of the candidate antennas as target antennas for receiving or sending the first communication system information. For a specific explanation, reference may be made to the related contents of preferentially selecting the target antenna of the second communication scheme, which are not described herein again. On the basis of preferentially selecting the target antenna of the first communication system, selecting the target antenna of the second communication system can be specifically realized as follows: selecting one or more antennas with the highest second communication score from the antennas of the second communication system of the candidate antennas as target antennas for receiving or sending information of the second communication system; or, for the multiple candidate antennas, selecting one or more antennas with the highest second communication system score from the antennas of the second communication system except the target antenna for receiving or sending the first communication system information as the target antenna for receiving or sending the second communication system information; or selecting a target antenna for receiving or sending the first communication system information as a target antenna for receiving or sending the second communication system information. For a detailed explanation, reference is made to the above description and no further explanation is given here.

Sub-case 4: the priority of the first communication system is higher than that of the second communication system, and for at least one antenna of the first communication system, the first communication parameter of the first communication system is greater than or equal to a first threshold, and for at least one antenna of the second communication system, the first communication parameter of the second communication system is smaller than the first threshold.

Different from the sub-case 3, in the sub-case 4, the coverage of the cell of the first communication system is better, and the coverage of the cell of the second communication system is worse, so that compared with the first communication system, the performance of the second communication system may have a larger influence on the overall communication performance of the device. Therefore, the target antenna of the second communication system is preferably selected, so that the overall communication performance of the equipment is improved.

Specifically, the device preferentially selects the target antenna of the second communication system, which can be implemented as follows: and selecting one or more antennas with the highest second communication mode score from the antennas of the second communication mode of the candidate antennas as target antennas for receiving or sending the second communication mode information.

On the basis of preferentially selecting the target antenna of the second communication system, selecting the target antenna of the first communication system can be realized as follows: selecting one or more antennas with the highest first communication score from the antennas of the first communication system of the candidate antennas as target antennas for receiving or sending first communication system information; or, for the multiple candidate antennas, selecting one or more antennas with the highest first communication system score from the antennas of the first communication system except the target antenna for receiving or sending the second communication system information as the target antenna for receiving or sending the first communication system information; or selecting a target antenna for receiving or sending the second communication system information as the target antenna for receiving or sending the first communication system information.

Sub-case 5: the priority of the first communication system is higher than that of the second communication system, and for at least one antenna of the first communication system, the first communication parameter of the first communication system is smaller than a first threshold, and for at least one antenna of the second communication system, the first communication parameter of the second communication system is smaller than the first threshold.

Unlike the sub-case 2, in the sub-case 5, when the coverage of the cell of the first communication system is poor, the device needs to determine whether the coverage of the cell of the second communication system is also poor. If the coverage of the second communication system cell is also poor, the device preferentially selects the high-priority communication system, namely the target antenna of the first communication system, so as to improve the processing efficiency of the high-priority communication system signal. For the specific implementation manner of preferentially selecting the target antenna of the first communication system, reference may be made to the above, which is not described herein again. On the basis of preferentially selecting the target antenna of the first communication system, the specific implementation manner of selecting the target antenna of the second communication system can be also referred to above.

Sub-case 6: the priority of the first communication system is higher than that of the second communication system, the first communication parameter of the first communication system is smaller than a first threshold for at least one antenna of the first communication system, and the first communication parameter of the second communication system is larger than or equal to the first threshold for at least one antenna of the second communication system.

Different from the sub-case 5, in the sub-case 6, the coverage of the cell of the first communication system is poor, and the coverage of the second communication system is good, so that compared with the second communication system, the influence of the performance of the first communication system on the communication performance of the whole equipment may be larger, and therefore, the target antenna of the first communication system is preferentially selected, so that the communication performance of the whole equipment is improved.

Case 2: the priority of the first communication system is equal to the priority of the second communication system.

In case 2, the following 2 seed cases can be divided:

sub-case 7: when the priority of the first communication system is equal to that of the second communication system, and the difference value between the first weighted summation result of the first antenna group and the second weighted summation result of the second antenna group is smaller than or equal to a second threshold, selecting at least one target antenna comprising the first antenna group, wherein the third weighted summation result of the first antenna group is higher than the fourth weighted summation result of the second antenna group; or, at least one target antenna including the second antenna group is selected, wherein the third weighted sum result of the first antenna group is lower than the fourth weighted sum result of the second antenna group. The first weighted sum result is a weighted sum result of a first communication parameter of a first communication system and a first communication parameter of a second communication system for one or more antennas included in a first antenna group in the multiple candidate antennas, and the second weighted sum result is a weighted sum result of a first communication parameter of the first communication system and a first communication parameter of the second communication system for one or more antennas of a second antenna group in the multiple candidate antennas. The third weighted sum result is a weighted sum result of the first communication system score and the second communication system score for one or more antennas in the first antenna group. The fourth weighted sum result is a weighted sum result of the first communication system score and the second communication system score for one or more antennas in the second antenna group.

For one or more antennas in a certain antenna group, a weighted summation result of a first communication parameter of a first communication scheme and a first communication parameter of a second communication scheme, that is, a first weighted summation result or a second weighted summation result, may be referred to as a first communication parameter of the antenna group. For example, referring to fig. 3, the first antenna group includes an antenna 1, the second antenna group includes an antenna 2 and an antenna 3, the transmission margin for the antenna 1 to operate at NR is x, the transmission margin for the antenna 1 to operate at LTE is y, the transmission margin for the antenna 2 to operate at NR is m, and the transmission margin for the antenna 3 to operate at LTE is n. The weighted summation result of the NR transmission margin and the LTE transmission margin of the antenna 1 in the first antenna group may be x + y, for example, that is, the first communication parameter of the first antenna group is x + y. Or, may be x²+y ²(which may be considered a special weighted sum, with weights equal to the parameters themselves), or other forms of weighted sum results such as k1.x + k2.y (where the symbol ". multidot." may denote a multiplication), K1, K2 may be constant, or variable. The weighted sum of the NR transmission margin of antenna 2 and the LTE transmission margin of antenna 3 in the second antenna group may be m + n, i.e., the first communication parameter of the second antenna group is m + n. Or may be m²+n ²Or otherwise.

In the embodiment of the present application, when the difference value of the first communication parameter between the first antenna group and the second antenna group is smaller, it indicates that the power potential of the first antenna group is not much different from the power potential of the second antenna group, and in this case, the antenna group with a higher score weighted sum result may be further selected as one or more target antennas according to the antenna scores. For example, referring to fig. 3, when the difference between the first weighted sum result x + y of the first antenna group and the second weighted sum result m + n of the second antenna group is small, if the sum of the LTE score and the NR score of the antenna 1 in the first antenna group (i.e., the third weighted sum result of the first antenna group) is greater than or equal to the sum of the NR score of the antenna 2 and the LTE score of the antenna 3 in the second antenna group (i.e., the fourth weighted sum result of the second antenna group), the device selects the antenna 1 as a target antenna for processing the LTE information and the NR information. Conversely, if the sum of the LTE score and the NR score of antenna 1 is less than the sum of the NR score of antenna 2 and the LTE score of antenna 3, the device selects antenna 2 and antenna 3 as target antennas for processing the NR information and the LTE information.

Sub-case 8: when the priority of the first communication system is equal to the priority of the second communication system, and a difference value between a first weighted summation result of the first antenna group and a second weighted summation result of the second antenna group is greater than a second threshold, determining at least one target antenna comprising the first antenna group, wherein the first weighted summation result of the first antenna group is higher than (i.e., greater than or equal to) the second weighted summation result of the second antenna group. Alternatively, at least one target antenna comprising a second antenna group is determined, wherein a first weighted sum result of the first antenna group is lower than a second weighted sum result of the second antenna group.

In this embodiment, when the difference value of the first communication parameter between the first antenna group and the second antenna group is larger, it indicates that the power potential of the first antenna group is larger than that of the second antenna group, and in this case, one or more antennas in the antenna group with larger first communication parameter may be directly selected as the target antenna. For example, when the first communication parameter (x + y) of the first antenna group is much larger than the first communication parameter (m + n) of the second antenna group, the device selects an antenna in the first antenna group, that is, the antenna 1, as a target antenna for processing LTE information and NR information due to the larger power potential of the first antenna group. On the contrary, when the first communication parameter (x + y) of the first antenna group is much smaller than the first communication parameter (m + n) of the second antenna group, the device selects the antennas in the second antenna group, i.e., the antenna 2 and the antenna 3, as the target antennas for processing the LTE information and the NR information.

S203, the device performs communication through at least one target antenna. As described above, taking the device needs to process the signals of the first communication scheme and the second communication scheme as an example, S203 may be implemented as: and sending or receiving information of the first communication system and the second communication system through at least one target antenna.

According to the antenna switching method provided by the embodiment of the application, the device acquires the priorities of the multiple communication systems of the device and the communication parameters of the multiple candidate antennas of the device, so that at least one target antenna used for sending or receiving information of the multiple communication systems in the multiple candidate antennas can be determined according to the priorities and the communication parameters respectively corresponding to the multiple candidate antennas. Because the priority of different communication systems and the communication parameters of different communication systems are considered, the device selects the target antenna suitable for the current communication scene under the multi-communication system, and the communication performance under the multi-communication system is improved.
