Description

Antenna switching method and device, signal transceiving circuit and electronic equipment

Technical Field

Background

Currently, in a 5G non-independent (NSA) networking architecture, a signal transceiving end of a terminal device is generally configured with multiple antennas, and meanwhile, since a 4G base station and a 5G base station in the NSA networking architecture coexist, the signal transceiving end of the terminal device is generally configured with a 4G antenna and a 5G antenna, so that the terminal device can respectively transceive a 4G signal and a 5G signal through the 4G antenna and the 5G antenna.

However, due to the limited internal space of the terminal device, the distance between the 4G antenna and the 5G antenna in the terminal device is small, so that interference is generated between the 4G antenna and the 5G antenna, and further, a 4G signal received by the 4G antenna is distorted, or a 5G signal received by the 5G antenna is distorted.

For example, when a 4G antenna in the terminal device transmits a 4G signal and a 5G antenna receives a 5G signal, the 5G antenna in the terminal device receives the 5G signal and also receives an interference signal transmitted by the 4G antenna at the same time as the 5G signal due to interference between the 4G antenna and the 5G antenna, so that the 5G signal received by the 5G antenna is distorted.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. The objects distinguished by "first" and "second" are usually a group, and the number of the objects is not limited, and for example, the first object may be one or more. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

Fig. 1 is a schematic structural diagram of a typical 4G and 5G dual-connection signal transceiver. As shown in fig. 1, the signal transceiver 200 includes a transceiver 201, a 4G power amplification module 202, a 4G diversity receiving module 203, a 5G power amplification module 204, a first 5G receiving module 205, a second 5G receiving module 206, a third 5G receiving module 207, a first rf switch 208, a second rf switch 209, a first 4G antenna 210, a second 4G antenna 211, a first 5G antenna 212, a second 5G antenna 213, a third 5G antenna 214, and a fourth 5G antenna 215, where: the transceiver 201, the 4G power amplification module 202, the first radio frequency switch 208 and the first 4G antenna 210 are connected in sequence; the transceiver 201, the 4G diversity receiving module 203, the first rf switch 208, and the second 4G antenna 211 are sequentially connected; the transceiver 201, the 5G power amplification module 204, the second rf switch 209, and the first 5G antenna 212 are connected in sequence; the transceiver 201, the first 5G receiving module 205, the second rf switch 209 and the second 5G antenna 213 are connected in sequence; the transceiver 201, the second 5G receiving module 206 and the third 5G antenna 214 are connected in sequence; the transceiver 201, the third 5G receiving module 207, and the fourth 5G antenna 215 are connected in sequence.

For example, the transceiver 101 is used for receiving or transmitting 4G signals and receiving or transmitting 5G signals; the 4G power amplification module 202 is configured to perform power amplification, filtering, and other processing on the received or transmitted 4G signal; the 5G power amplification module 204 is configured to perform power amplification, filtering, and other processing on the received or transmitted 5G signal; the first rf switch 208 is used to switch the first 4G antenna 210 and the second 4G antenna 211; the second rf switch 209 is used to switch the first 5G antenna 212 and the second 5G antenna 213; the 4G diversity receiving module 203 is configured to perform power amplification, filtering, and other processing on the received 4G signal; the first 5G receiving module 205, the second 5G receiving module 206, and the third 5G receiving module 207 are respectively configured to perform power amplification, filtering, and other processing on the received 5G signal.

For example, taking the transceiver 201 as an example of transmitting 4G signals and receiving 5G signals and using the first 4G antenna 210 and the first 5G antenna 212 by default, the transceiver 201 generates a second harmonic (i.e. an interference signal) while generating a 4G original signal, i.e. the 4G signal generated by the transceiver 201 includes: the 4G original signal and the above interference signal, the first 4G antenna 210 will transmit the 4G signal to the corresponding 4G base station. Meanwhile, if the frequency of the interference signal is just within the receiving frequency band of the first 5G antenna 212 for receiving the 5G signal, the first 4G antenna 210 couples the interference signal to the first 5G antenna 212, so that the first 5G antenna 212 receives the 5G original signal and also receives the interference signal, which causes interference to the 5G original signal.

For example, when the electronic device operates in the 4G B3 frequency band (with frequencies from 1710MHz to 1785 MHz), it is assumed that the transceiver 201 generates a first harmonic with a frequency of 1750MHz and also generates a second harmonic with a frequency of 3500 MHz. If the electronic device operates in the 5G nq 78 frequency band (i.e. the frequency is 3300MHz to 3800 MHz), the frequency of the second harmonic is just in the frequency band of the electronic device receiving the 5G signal, so the terminal device receives the 5G signal and the second harmonic at the same time, and the second harmonic may cause interference to the 5G signal received by the electronic device.

To solve the above problem, an embodiment of the present application provides an antenna switching method, where first, when a first communication mode and a second communication mode of an electronic device operate simultaneously, an antenna switching apparatus may acquire a first operating parameter of a first antenna (for transmitting a signal in the first communication mode) and a second operating parameter of a second antenna (for receiving a signal in the second communication mode). Then, the antenna switching device may determine whether the signal transmitted by the first antenna interferes with the signal received by the second antenna according to the first operating parameter and the second operating parameter. Finally, the antenna switching means may transmit the signal of the first communication mode through the target antenna in a case where it is determined that the interference is generated. Through the scheme, the antenna switching device can respectively acquire the first working parameter of the first antenna and the second working parameter of the second antenna when the electronic equipment works in the first communication mode and the second communication mode. Then, if the antenna switching device determines that the signal sent by the first antenna interferes with the signal received by the second antenna according to the first operating parameter and the second operating parameter, the antenna switching device may switch the first antenna to a target antenna, and send the signal in the first communication mode through the target antenna. Because the interference of the signal transmitted by the target antenna on the signal received by the second antenna is smaller than the interference of the signal transmitted by the first antenna on the signal received by the second antenna, the interference of the signal transmitted by the antenna switching device in the first communication mode on the signal received by the second communication mode can be reduced.

The term "coupling" as used in the embodiments of the present application refers to the phenomenon that two or more circuit elements or inputs and outputs of an electrical network have a close fit and an interaction, and transfer energy from one side to the other side by interaction. For example, the process of coupling the interference signal to the 5G antenna by the 4G antenna is equivalent to the process of transmitting the interference signal to the 5G antenna by the 4G antenna.

The antenna switching method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Fig. 2 is a schematic flowchart of an antenna switching method according to an embodiment of the present application, including steps 301 to 303:

step 301: the antenna switching device acquires a first working parameter of the first antenna and a second working parameter of the second antenna under the condition that the first communication mode and the second communication mode of the electronic equipment work simultaneously.

The first antenna is used for transmitting signals in a first communication mode, and the second antenna is used for receiving signals in a second communication mode.

In this embodiment of the present application, the electronic device may be an antenna switching device, and may also be a device including an antenna switching device, which is not limited in this embodiment of the present application.

In an embodiment of the present application, the electronic device may include at least three antennas, where the at least three antennas include a first antenna, a second antenna, and a target antenna described below.

In the embodiment of the present application, the first communication mode may be any one of the following: 2G, 3G, 4G and 5G. The second communication mode may be any one of the following: 2G, 3G, 4G and 5G.

In the embodiment of the present application, the first communication mode and the second communication mode are different communication modes. For example, if the first communication mode is 4G, the second communication mode is 5G; if the first communication mode is 5G, the second communication mode is 4G.

It should be noted that the electronic device may support the first communication mode and the second communication mode, and since no interference is generated when the electronic device operates only in the first communication mode or only in the second communication mode, the antenna switching device may determine the operating state of the electronic device, and if the electronic device needs to operate in both the first communication mode and the second communication mode, step 301 to step 303 are executed.

In an embodiment of the present invention, the first antenna is an antenna corresponding to a first communication mode, and the second antenna is an antenna corresponding to a second communication mode. For example, the first antenna may be a 4G antenna if the first communication mode is 4G, and the second antenna may be a 5G antenna if the second communication mode is 5G.

If the first communication mode is 4G and the electronic device corresponds to a plurality of 4G antennas, the first antenna may be any one of the plurality of 4G antennas. If the second communication mode is 5G and the electronic device corresponds to a plurality of 5G antennas, the second antenna may be any one of the plurality of 5G antennas.

In an embodiment of the present application, the first operating parameter of the first antenna may include at least one of: the working frequency band parameter of the first antenna and the channel parameter of the first antenna. The second operating parameter of the second antenna may include at least one of: the working frequency band parameter of the second antenna and the channel parameter of the second antenna.

For example, the operating band parameter in the present application may be an identifier of an operating band, where the identifier of the operating band may include at least one of: name of the operating band, frequency of the operating band. For example, the operating band name of the first antenna may be B3, and the operating band name of the second antenna may be N78.

It should be noted that there may be one or multiple working frequency bands corresponding to the first antenna, and the embodiment of the present application is not limited thereto. For example, the operating frequency band corresponding to the first antenna may be B3 or B8.

It should be noted that there may be one or more operating frequency bands corresponding to the second antenna, and the embodiment of the present application is not limited thereto. For example, the operating frequency band corresponding to the second antenna may be N78, and may also be N79.

For example, the channel parameter in the present application may be an identifier of a channel, where the identifier of the channel may include at least one of: channel name, frequency of the channel.

It should be understood that the frequency in this application may be one frequency or a frequency range, and this is not limited in this embodiment of the application.

It should be noted that there may be one or multiple channels corresponding to the first antenna, and the embodiment of the present application is not limited thereto. One or more channels may be provided for the second antenna, which is not limited in this embodiment of the present application.

Step 302: and the antenna switching device determines whether the signal transmitted by the first antenna interferes with the signal received by the second antenna according to the first working parameter and the second working parameter.

In the embodiment of the application, under the condition that the first working parameter and the second working parameter are matched with the preset working parameter, the antenna switching device determines that the signal sent by the first antenna generates interference on the signal received by the second antenna; and under the condition that the first working parameter and the second working parameter are matched with the preset working parameter, the antenna switching device determines that the signal sent by the first antenna does not interfere with the signal received by the second antenna.

The preset working parameters may be set by default in the system or by a user, which is not limited in the embodiment of the present application. Illustratively, the preset operating parameters may include at least one of: presetting working frequency band parameters and channel parameters.

For example, after acquiring the first operating parameter and the second operating parameter, the antenna switching device may determine, according to the target table, whether the signal transmitted by the first antenna interferes with the signal received by the second antenna. The target table includes the preset operating parameters.

The target table may be set by default in the system, or may be set by the user, which is not limited in the embodiment of the present application.

For example, the target table may indicate an operating parameter capable of generating interference, and may also indicate an operating parameter incapable of generating interference, which is not limited in this embodiment of the present application.

For example, the data included in the target table may be obtained through experiments.

In an example, in a case that the preset operating parameter includes a preset operating frequency band parameter, the preset operating parameter may be a preset operating frequency band parameter combination. Specifically, the preset operating band parameter combination may include an operating band parameter combination capable of generating interference. For example, the preset operating band combination may include a 4G operating band name B3 and a 5G operating band name N78.

For example, after the antenna switching device obtains the operating frequency band name B3 of the first antenna and the operating frequency band name N78 of the second antenna, the antenna switching device may perform a search in the target table, and if the target table includes the operating frequency band name B3 and the operating frequency band name N78, it is determined that the signal transmitted by the first antenna may generate interference on the signal received by the second antenna.

In one example, in a case that the preset operating parameter includes a preset channel parameter, the preset operating parameter may be a preset channel parameter combination. The predetermined channel parameter combinations may include combinations that are capable of generating interference channel parameters. For example, the preset channel parameters may include a channel name a00 corresponding to the frequency band B3 and a channel name B00 corresponding to the frequency band N78.

For example, after the antenna switching apparatus obtains the channel name of the first antenna as a00 and the channel name of the second antenna as B00, the antenna switching apparatus may perform a lookup in the target table, and if the target table includes the channel name a00 and the channel name B00, it is determined that the signal transmitted by the first antenna may generate interference on the signal received by the second antenna.

It should be noted that the target table may include, in addition to the preset operating parameters, identifiers of all antennas included in the electronic device that may generate interference. For example, the identifier of the antenna may be an antenna name, an antenna number, or any identifier capable of identifying the antenna, which is not limited in this embodiment of the application.

Illustratively, table 1 is a possible 4G antenna and 5G antenna interference lookup table.

TABLE 1

Step 303: the antenna switching device transmits a signal of the first communication mode through the target antenna in a case where it is determined that the interference is generated.

In this embodiment, the target antenna may be a newly added antenna or an existing antenna, which is not limited in this embodiment. For example, the target antenna may be a 4G antenna or a 5G antenna.

In the embodiment of the present application, the interference generated by the target antenna for transmitting the signal in the first communication mode to the second antenna for receiving the signal in the second communication mode is smaller than the interference generated by the first antenna for transmitting the signal in the first communication mode to the second antenna for receiving the signal in the second communication mode.

In one example, the above-mentioned target antenna transmitting the signal of the first communication mode does not interfere with the second antenna receiving the signal of the second communication mode.

It is understood that the antenna switching device may switch the first antenna to a target antenna and transmit the signal of the first communication mode through the target antenna in the case where it is determined that the interference is generated.

It should be noted that the antenna switching device may not perform any operation when it is determined that the signal transmitted by the first antenna does not interfere with the signal received by the second antenna.

For example, referring to table 1, taking the first communication mode as 4G and the second communication mode as 5G as an example, when the mobile phone is powered on, the 4G communication is defaulted to operate in the B3 frequency band, and the antenna ANT0 is used; the 5G communication operates in the N78 band using an antenna ANT2. When the mobile phone detects that the current 4G and 5G work simultaneously, the mobile phone may obtain the channel name a00 of the antenna ANT0 and the working frequency band name N78 of the antenna ANT2. Then, the handset may perform matching in the frequency band name combination corresponding to the list of ANT0 and ANT2 in the interference lookup table. If the preset frequency band name combination is matched, it indicates that the mobile phone uses the antenna ANT0 and the antenna ANT2, and the 4G communication works in the B3 frequency band and the 5G communication works in the N78 frequency band, which may generate interference. At this time, the mobile phone may query whether the antennas ANT0' and ANT2 that may also transmit the 4G signal exist in the interference lookup table, and if not, the mobile phone may switch the antenna ANT0 to the antenna ANT0', and transmit the 4G signal through the antenna ANT0 '.

In the antenna switching method provided in the embodiment of the present application, first, in a case that the antenna switching device operates in the first communication mode and the second communication mode of the electronic device simultaneously, the antenna switching device may acquire a first operating parameter of the first antenna (for transmitting a signal in the first communication mode) and a second operating parameter of the second antenna (for receiving a signal in the second communication mode). Then, the antenna switching device may determine whether the signal transmitted by the first antenna interferes with the signal received by the second antenna according to the first operating parameter and the second operating parameter. Finally, the antenna switching means may transmit a signal of the first communication mode through the target antenna in a case where it is determined that the interference is generated. Through the scheme, the antenna switching device can respectively acquire the first working parameter of the first antenna and the second working parameter of the second antenna under the condition that the electronic equipment works in the first communication mode and the second communication mode. Then, if the antenna switching device determines that the signal sent by the first antenna interferes with the signal received by the second antenna according to the first operating parameter and the second operating parameter, the antenna switching device may switch the first antenna to a target antenna, and send the signal in the first communication mode through the target antenna. Because the interference of the signal transmitted by the target antenna on the signal received by the second antenna is smaller than the interference of the signal transmitted by the first antenna on the signal received by the second antenna, the interference of the signal transmitted by the antenna switching device in the first communication mode on the signal received by the second communication mode can be reduced.

Optionally, in this embodiment of the present application, since the first antenna and the second antenna may correspond to a plurality of operating frequency bands, each operating frequency band may correspond to a plurality of channels, and the antenna switching device may not generate interference when receiving and transmitting signals on the plurality of channels. Therefore, the antenna switching device may further compare the channel parameters corresponding to the operating frequency band after determining the operating frequency band parameters.

Illustratively, the step 302 may specifically include the following steps 302a and 302b:

step 302a: and the antenna switching device acquires the target channel parameters under the condition that the target working frequency band parameters are matched with the preset frequency band parameters.

The target working frequency band parameter is a working frequency band parameter of the first antenna and a working frequency band parameter of the second antenna; the target channel parameters are channel parameters of the first antenna and channel parameters of the second antenna.

For example, in the case that the target operating frequency band parameter is an operating frequency band parameter of the first antenna and an operating frequency band parameter of the second antenna, the preset operating frequency band parameter may be a combination of the preset operating frequency band parameters.

Illustratively, the target channel parameter is a channel parameter corresponding to the target operating frequency band parameter.

It should be noted that, in the case that the target operating band parameter does not match the preset band parameter, the antenna switching apparatus may not perform any operation.

Step 302b: and the antenna switching device determines that the signal sent by the first antenna generates interference on the signal received by the second antenna under the condition that the target channel parameter is matched with the preset channel parameter.

For example, in the case that the target channel parameter is a channel parameter of the first antenna and a channel parameter of the second antenna matched, the preset channel parameter may be a combination of the preset channel parameters described above.

For example, after determining the target operating frequency band parameter, the antenna switching apparatus may determine whether the target operating frequency band parameter matches the preset frequency band parameter according to the target table. Then, the antenna switching apparatus may continue to determine whether the target channel parameter matches the preset channel parameter according to the target table.

For example, referring to table 1, taking the first communication mode as 4G and the second communication mode as 5G as an example, when the mobile phone is powered on, the 4G communication is defaulted to operate in the B3 frequency band, and the antenna ANT0 is used; the 5G communication operates in the N78 band using an antenna ANT2. When the mobile phone detects that the current 4G and 5G work simultaneously, the mobile phone may obtain the working frequency band name B3 of the antenna ANT0 and the working frequency band name N78 of the antenna ANT2. Then, the handset may perform matching in the frequency band name combination corresponding to the list of ANT0 and ANT2 in the interference lookup table. If the preset frequency range name combination is matched, it is indicated that the mobile phone uses the antenna ANT0 and the antenna ANT2, and interference may be generated when the 4G communication works in the B3 frequency range and the 5G communication works in the N78 frequency range, and then the mobile phone obtains the channel name a00 of the antenna ANT0 and the channel name B00 of the antenna ANT2. Then, if the mobile phone matches in the channel name combination corresponding to the B3 frequency band and the N78 frequency band combination in the interference lookup table, if the preset channel name combination is matched, it indicates that the mobile phone uses the antenna ANT0 and the antenna ANT2, and interference occurs when the 4G communication works in the B3 frequency band and the 5G communication works in the N78 frequency band.

It should be noted that, in the case where the target channel parameter is the channel parameter of the first antenna and the channel parameter of the second antenna, the antenna switching device may not perform any operation.

The antenna switching method provided by the embodiment of the application can be applied to a scene of improving accuracy of judging interference, a plurality of working frequency bands correspond to a first antenna and a second antenna, each working frequency band can correspond to a plurality of channels, an antenna switching device can roughly judge whether a combination of a working frequency band parameter of the first antenna and a working frequency band parameter of the second antenna generates interference or not, if the interference is likely to be generated, the antenna switching device obtains a combination of a channel parameter of the first antenna and a channel parameter of the second antenna to perform fine judgment, and under the condition that a target channel parameter is matched with a preset channel parameter, the antenna switching device determines that a signal sent by the first antenna generates interference on a signal received by the second antenna, so that the accuracy of judgment can be improved.

Optionally, in this embodiment of the application, when the electronic device further includes a plurality of antennas in addition to the first antenna and the second antenna, the antenna switching device further needs to determine the target antenna from the plurality of antennas.

Illustratively, after determining that the signal transmitted by the first antenna interferes with the signal received by the second antenna in step 303b, the method may further include the following step A1:

step A1: the antenna switching device determines a target antenna that satisfies a switching condition from among antennas other than the first antenna and the second antenna in the electronic apparatus.

Wherein the handover condition indicates: in the case where the target antenna transmits the signal of the first communication mode, the degree of signal interference to the second antenna for receiving the signal of the second communication mode is minimized.

In one example, in the case that the target antenna transmits the signal in the first communication mode, the minimum signal interference degree for the second antenna to receive the signal in the second communication mode is: the target antenna transmits the signal of the first communication mode, and the second antenna does not generate interference for receiving the signal of the second communication mode.

Illustratively, the target antenna satisfying the handover condition is any one of: an antenna with channel parameters not matched with target preset channel parameters; and under the condition that the channel parameters of all antennas except the first antenna and the second antenna in the electronic equipment are matched with the preset channel parameters, the antenna with the minimum interference degree on the second antenna. When all antennas except the second antenna in the electronic device send signals, an error value between a signal received by the second antenna and an original signal may represent an interference degree to the second antenna, where a larger error value represents a stronger interference degree to the second antenna, and conversely, a weaker interference degree to the second antenna.

It can be understood that when the channel parameter of only one antenna in all antennas except the first antenna and the second antenna in the electronic device does not match with the target preset channel parameter, the antenna is the target antenna.

In one example, the antennas satisfying the switching condition include at least two antennas; the target antenna is an antenna satisfying a predetermined condition among the at least two antennas.

Wherein the predetermined condition comprises at least one of: the received signal has the strongest signal strength, the highest signal integrity and the best signal quality.

Example 1, when the at least two antennas whose channel parameters do not match the target preset channel parameters include at least two antennas, the target antenna of the antenna switching apparatus is an antenna with the strongest signal strength of the received signal of the at least two antennas.

Example 2, in the case that the channel parameters of all antennas except the first antenna and the second antenna in the electronic device are matched with the preset channel parameters, when at least two antennas with the minimum interference degree to the second antenna are included, that is, the interference degrees of the at least two antennas to the second antenna are the minimum and the same, the target antenna is an antenna with the strongest received signal strength among the at least two antennas.

For example, the signal strength of the received signal may be determined by a Received Signal Strength Indication (RSSI). The larger the RSSI value is, the stronger the signal strength of the antenna reception signal is, and conversely, the weaker the signal strength of the antenna reception signal is.

It is to be understood that the predetermined condition is that the signal strength of the received signal is strongest, i.e. the predetermined condition is that the value of the received signal strength indication is maximum.

The antenna switching method provided by the embodiment of the application can be applied to a scene that a target antenna is determined from a plurality of antennas, and the antenna switching device can determine an antenna which transmits a signal in a first communication mode and has the smallest interference on a second antenna to receive a signal in a second communication mode as the target antenna.

Optionally, in this embodiment of the present application, after step 303, the method may further include the following steps: the antenna switching device may re-determine the first communication mode and the second communication mode of the electronic device when detecting that the electronic device switches channels or cells, and may re-acquire the operating parameters of the target antenna and the operating parameters of the second antenna when the first communication mode and the second communication mode of the electronic device operate simultaneously, and then may determine whether a signal transmitted by the target antenna interferes with a signal received by the second antenna according to the operating parameters of the target antenna and the operating parameters of the second antenna. Finally, the antenna switching means transmits the signal of the first communication mode through the antenna newly determined in the case where it is determined that the interference is generated. For a specific determination process, reference may be made to the description of determining a target antenna in the embodiment of the present application, and details are not described here. By analogy, the antenna switching device can perform the above steps each time the electronic device is detected to switch channels or cells, so that the communication interference can be reduced.

It should be noted that the antenna switching apparatus may detect a cell or a channel where the electronic device is currently located according to a predetermined time interval, and determine whether the electronic device switches the cell or the channel by comparing the cell or the channel detected last time.

It should be noted that the antenna switching apparatus may maintain the current antenna configuration when detecting that the electronic device does not switch channels or cells.
