Description

Signal transmitting and receiving device, electronic equipment and control method

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a signal receiving and transmitting device, electronic equipment and a control method.

Background

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

However, because the operating frequencies of the part 4G signal and the part 5G signal are close to or even the same, and because the internal space of the terminal device is limited, the distance between the 4G antenna and the 5G antenna in the terminal device is small, thereby causing the problem of co-channel interference between the 4G signal and the 5G signal. In order to solve the interference problem, the existing terminal device mainly avoids signal interference between the 4G signal and the 5G signal by closing the 5G signal receiving channel when transmitting the 4G signal, or closing the 4G signal receiving channel when transmitting the 5G signal.

However, when the terminal device receives the 5G signal while transmitting the 4G signal or receives the 4G signal while transmitting the 5G signal, the terminal device temporarily stops receiving the 4G signal or the 5G signal, which not only causes a delay in the signal but also causes a loss of the signal.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

Taking the case that a 4G transmission signal interferes with a 5G reception signal, and a low noise amplifier in an interfered 5G reception path is turned off, fig. 1 is a schematic structural diagram of a typical 4G +5G dual-connection signal transceiver in which a 4G antenna and a 5G antenna coexist (i.e., the 4G signal and the 5G signal do not share an antenna), as shown in fig. 1, the signal transceiver 100 includes a 4G radio frequency transceiver 101, a 5G radio frequency transceiver 102, a first power amplifier 103, a second power amplifier 104, a first low noise amplifier 105, a second low noise amplifier 106, a first filter 107, a second filter 108, a third filter 109, a fourth filter 110, a first radio frequency switch 111, a second radio frequency switch 112, a 4G antenna 113, a 5G antenna 114, and a CPU115, wherein: the 4G rf transceiver 101, the first power amplifier 103, the first low noise amplifier 105, the first filter 107, the third filter 109, the first rf switch 111, and the 4G antenna 113 are sequentially connected; the 5G rf transceiver 102, the second power amplifier 104, the second low noise amplifier 106, the second filter 108, the fourth filter 110, the second rf switch 112, and the 5G antenna 114 are connected in sequence.

For example, the 4G rf transceiver 101 is used to receive or transmit 4G signals; the 5G rf transceiver 102 is used for receiving or transmitting 5G signals; the first power amplifier 103 and the second power amplifier 104 are used for amplifying the power of the signal; the first low noise amplifier 105 and the second low noise amplifier 106 are used to improve the signal-to-noise ratio; the first rf switch 111 is configured to implement switching between receiving and transmitting 4G signals, and the first rf switch 111 is further configured to implement switching between different 4G frequency bands; the second rf switch 112 is configured to implement switching between receiving and transmitting of 5G signals, and the second rf switch 112 is further configured to implement switching between different 5G frequency bands; the 4G antenna 113 is configured to transmit a 4G signal sent by the 4G radio frequency transceiver 101 to a 4G base station, or receive a 4G signal transmitted by the 4G base station; the 5G antenna 114 is used for transmitting the 5G signal sent by the 5G rf transceiver 102 to the 5G base station, or receiving the 5G signal transmitted by the 5G base station.

For example, taking the 4G rf transceiver 101 sending the 4G signal and the 5G rf transceiver 102 receiving the 5G signal as an example, after the 4G rf transceiver 101 generates the 4G signal, the 4G signal is sent out through the 4G antenna 113. However, if the frequency of the 4G signal is just within the receiving band of the 5G antenna 114 for receiving the 5G signal, the 4G antenna 113 couples the 4G signal into the 5G antenna 114. So that the 5G antenna 114 receives the 5G signal and also receives the 4G signal, and the 4G signal may cause interference to the 5G signal.

In order to solve the above interference problem, the conventional signal transceiver mainly avoids signal interference between the 4G signal and the 5G signal by closing the 5G signal receiving channel when transmitting the 4G signal, or avoids signal interference between the 5G signal and the 4G signal by closing the 4G signal receiving channel when transmitting the 5G signal.

For example, taking the case where the 4G rf transceiver 101 transmits a 4G signal and the 5G rf transceiver 102 receives a 5G signal as an example, as shown in fig. 1, the CPU115 in the transceiver device turns off the second low noise amplifier 106 by sending a control signal to the second low noise amplifier 106, so that the 5G rf transceiver 102 cannot receive the 5G signal.

In order to solve the above problems, embodiments of the present invention provide a signal transceiver, an electronic device, and a control method, in which an interference processing circuit and a control circuit are added to an existing signal transceiver, so that the signal transceiver can solve the problems of transmission delay and signal loss in the signal transceiving process of the existing signal transceiver. Specifically, when the first sending circuit sends a first signal and the second receiving circuit receives a second signal, the control circuit in the signal transceiver switches on a path between the interference processing circuit and the first sending circuit, so that the interference processing circuit generates an adjusted first signal and cancels the first signal received by the second receiving circuit, thereby reducing or even eliminating the interference of the first signal on the second signal; meanwhile, under the condition that the second sending circuit sends a third signal and the first receiving circuit receives a fourth signal, the control circuit in the signal transceiver enables the interference processing circuit to generate an adjusted third signal to cancel the third signal received by the first receiving circuit by conducting a path between the interference processing circuit and the second sending circuit, so that the interference of the third signal on the fourth signal is reduced or even eliminated, and the problems of transmission delay and loss of the third signal and the fourth signal caused by closing the second receiving circuit when the first sending circuit sends the first signal and closing the first receiving circuit when the second sending circuit sends the third signal are avoided.

The cancellation mentioned in the embodiments of the present invention means that two signals with opposite phases and the same amplitude are cancelled by using the radio frequency interference cancellation technology. Wherein, the radio frequency interference cancellation technology refers to: the interference signal is compared with a vector in a rectangular space coordinate system by utilizing the principle of vector synthesis and superposition, and the two vectors are synthesized by finding an inverse vector with the same information characteristic (such as the amplitude of the signal) as the vector, namely finding a signal with the phase opposite to that of the interference signal and the same amplitude, thereby canceling the interference signal.

It should be noted that the signals with the same amplitude as described above mean that the absolute difference between the amplitudes of the two signals is greater than or equal to 0 and less than or equal to a predetermined threshold, that is, the amplitudes of the two signals may tend to be the same.

For example, vector a is an interference signal, vector B is a reversed vector with the same information characteristic as vector a, and is used for canceling the interference signal, and the two vectors are combined and superimposed, so that the obtained vector C tends to be zero, that is, the interference signal almost disappears. It is understood that the process of "canceling" is the process of the resultant superposition of vector a and vector B.

The term "coupled" as used in the embodiments of the present invention refers to a phenomenon in which two or more circuit elements or inputs and outputs of an electrical network are closely fitted and interact with each other, and energy is transmitted 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.

It should be noted that "/" in this context means "or", for example, A/B may mean A or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.

It should be noted that "a plurality" herein means two or more than two.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

It should be noted that, for the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same items or similar items with substantially the same functions or actions, and those skilled in the art can understand that the words such as "first" and "second" do not limit the quantity and execution order. For example, the first signal and the second signal are used to distinguish different signals, rather than to describe a particular order of the signals.

Hereinafter, a signal transceiver and a control method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The first embodiment:

fig. 2 is a schematic structural diagram of a signal transceiver device according to an embodiment of the present invention, and as shown in fig. 2, the signal transceiver device 20 includes: a first transceiver circuit 21, a second transceiver circuit 22, an interference processing circuit 23, and a control circuit 24, wherein: the first transceiver circuit 21 includes: a first receiving circuit 212 and a first transmitting circuit 211; the second transceiver circuit 22 includes: a second receiving circuit 222 and a second transmitting circuit 221; the interference processing circuit 23 is connected to the first transceiver circuit 21, the second transceiver circuit 22, and the control circuit 24; the interference processing circuit 23 is connected to the first receiving circuit 212 and the second receiving circuit 222, respectively.

The control circuit 24 is configured to send a first control signal to the interference processing circuit 23 when the first sending circuit 211 sends a first signal and the second receiving circuit 222 receives a second signal, where the first control signal is used to conduct a path between the interference processing circuit 23 and the first sending circuit 211 so that the interference processing circuit 23 reduces or even eliminates interference of the first signal with the second signal.

And/or the presence of a gas in the gas,

the control circuit 24 is configured to transmit a second control signal to the interference processing circuit 23, when the second transmitting circuit 221 transmits a third signal and the first receiving circuit 212 receives a fourth signal, the second control signal being configured to turn on a path between the interference processing circuit 23 and the second transmitting circuit 221 so that the interference processing circuit 23 reduces or even eliminates interference of the fourth signal by the third signal.

In an embodiment of the present invention, the first transceiver circuit includes a first signal transceiver and a first antenna, wherein: the first signal transceiver is used for sending out a first signal and/or receiving a fourth signal. Example 1: the first transceiving antenna comprises a first transceiving antenna, and the first transceiving antenna is used for transceiving signals; example 2: the first antenna comprises a first transmitting antenna and a first receiving antenna, and the first transmitting antenna is used for transmitting signals, and the first receiving antenna is used for receiving signals.

In an embodiment of the invention, the second transceiver circuit includes a second signal transceiver and a second antenna, and the second signal transceiver is configured to send a third signal and/or receive a second signal. Example 3: the second antenna comprises a second transceiving antenna, and the second transceiving antenna is used for transceiving signals. Example 4: the second antenna comprises a second receiving antenna and a second transmitting antenna, and the second transmitting antenna is used for transmitting signals, and the second receiving antenna is used for receiving signals.

In addition, two or more antennas among the first transmitting antenna, the first receiving antenna, the second transmitting antenna, and the second receiving antenna may share the same antenna. For example, the second transmitting antenna, the second receiving antenna and the first receiving antenna may be the same antenna; alternatively, the first transmitting antenna and the second receiving antenna may be the same antenna; or, the second transmitting antenna and the first receiving antenna may be the same antenna, and may be specifically set according to actual use requirements, which is not limited in the present invention.

For example, when the first signal transceiver is a 4G rf transceiver and the second signal transceiver is a 5G rf transceiver, the first signal is a 4G transmit signal, the second signal may be a 5G receive signal, the third signal is a 5G transmit signal, and the fourth signal may be a 4G receive signal; when the first signal transceiver is a 5G radio frequency transceiver and the second signal transceiver is a 4G radio frequency transceiver, the first signal is a 5G transmit signal, the second signal may be a 4G receive signal, the third signal is a 4G transmit signal, and the fourth signal may be a 5G receive signal.

Optionally, in an embodiment of the present invention, as shown in fig. 3, the interference processing circuit 23 includes: target signal adjustment module 231. The target signal adjusting module is configured to reduce interference of the first signal with respect to the second signal when the first transmitting circuit 211 transmits the first signal and the second receiving circuit 222 receives the second signal, and/or reduce or even eliminate interference of the third signal with respect to the fourth signal when the second transmitting circuit 221 transmits the third signal and the first receiving circuit 212 receives the fourth signal.

Further optionally, with reference to fig. 3, as shown in fig. 4, the target signal adjusting module 231 includes: a first branching unit 2311, a second branching unit 2312, and a target signal adjusting unit 2313, wherein:

the target signal adjusting unit 2313 is connected to the first branching unit 2311 and the second branching unit 2312, respectively; the target signal adjusting unit 2313 is connected to the first receiving circuit 212 and the second receiving circuit 222, respectively.

The first shunting unit 2311 is connected to the first transmitting circuit 211, and is configured to, when a path between the first shunting unit 2311 and the target signal adjusting unit 2313 is turned on, split the first signal into two first signals, couple one first signal to the second receiving circuit 222 through the first transmitting circuit 211, and transmit the other first signal to the target signal adjusting unit 2313.

The second splitting unit 2312 is connected to the second transmitting circuit 221, and is configured to split the third signal into two third signals when a path between the second splitting unit 2312 and the target signal adjusting unit 2313 is turned on, couple one third signal to the first receiving circuit 212 through the second transmitting circuit 221, and transmit the other third signal to the target signal adjusting unit 2313.

The target signal adjusting unit 2313 is configured to adjust the another path of first signal, transmit the another path of adjusted first signal to the second receiving circuit 222 to cancel the one path of first signal, and/or adjust the another path of third signal, and transmit the another path of adjusted third signal to the first receiving circuit 212 to cancel the one path of third signal.

The phase of the first signal is opposite to that of the other adjusted signal, and the amplitude of the first signal is the same as that of the other adjusted signal, so that the first signal and the other adjusted signal are cancelled in the second receiving circuit; the phase of the one path of third signal is opposite to the phase of the other path of third signal after adjustment, and the amplitude of the one path of third signal is the same as the amplitude of the other path of first signal after adjustment, so that the one path of third signal is cancelled with the other path of third signal after adjustment in the first receiving circuit.

For example, the first shunt unit and the second shunt unit may be couplers (e.g., directional couplers) or power dividers, which is not limited by the present invention. Illustratively, the coupler may be any one of: the coupler comprises a 5dB coupler, a 6dB coupler, a 7dB coupler and a 10dB coupler, which can be determined according to actual use requirements, but the invention is not limited to the above; the power divider may be any one of the following: the second power divider, the third power divider, or the fourth power divider may be specifically determined according to actual use requirements, which is not limited in the present invention.

For example, the signal cancellation process will be described below by taking the first signal as an example.

It can be understood that, the phase of the one path of first signal is opposite to the phase of the other path of first signal after adjustment specifically means: the phase difference between the first signal of the first path and the adjusted first signal of the other path is 180 degrees.

It should be noted that, in an ideal situation, the interference processing circuit may adjust the phase of the another first signal to be opposite to the phase of the one first signal, and adjust the amplitude of the another first signal to be equal to the amplitude of the one first signal, but in an actual application scenario, due to the influence of hardware of the interference processing circuit or an external environment, the interference processing circuit cannot adjust the another first signal to be opposite to the phase of the one first signal and equal to the amplitude of the one first signal, that is, the signal processing apparatus cannot completely cancel, but can largely reduce the one first signal.

For example, when adjusting the first signal, the target signal adjusting unit may adjust the phase of the another first signal according to the target phase offset amount, and adjust the amplitude of the another first signal according to the target amplitude offset amount. The target phase offset may be a predetermined threshold, or may be flexibly set according to an actual application scenario, which is not limited in the present invention, and the target amplitude offset may be a predetermined threshold, or may be flexibly set according to an actual application scenario, which is not limited in the present invention. It should be noted that the target phase offset and the target amplitude offset may be obtained by simulating a process of transmitting the first signal in the signal processing apparatus.

It should be noted that, in the embodiment of the present invention, the signal cancellation process of the third signal may refer to the above description of the cancellation process of the first signal, and is not described herein again.

It should be noted that, in the embodiment of the present invention, the target signal adjusting unit may include one or more signal adjusting units, which is not limited in the present invention.

Further optionally, in an embodiment of the present invention, a signal adjusting unit at least includes: delayer, phase shifter and attenuator, wherein: the time delayer, the attenuator and the phase shifter are sequentially connected, or the time delayer, the phase shifter and the attenuator are sequentially connected, or the attenuator, the time delayer and the phase shifter are sequentially connected, or the attenuator, the phase shifter and the time delayer are sequentially connected, or the phase shifter, the time delayer and the attenuator are sequentially connected, or the phase shifter, the attenuator and the time delayer are sequentially connected.

The phase shifter is used for adjusting the phase of the other path of the first signal; the attenuator is used for adjusting the amplitude of the other path of the first signal; the delay unit is configured to delay an output time of the other path of the first signal to a first preset time. The first preset time period may be a preset threshold, or may be set according to actual use, which is not limited in the present invention.

Exemplarily, taking the case that a delayer, an attenuator and a phase shifter are connected in sequence, the delayer is configured to delay an output time of another received first signal to a first preset time period and then send the other received first signal to the phase shifter; the phase shifter is used for adjusting the phase of the other delayed path of first signal and sending the other path of phase-adjusted first signal to the attenuator, and the attenuator is used for adjusting the amplitude of the other path of phase-adjusted first signal and outputting the other path of amplitude-adjusted first signal.

According to the signal transceiver provided by the embodiment of the invention, the interference processing circuit and the control circuit are added in the existing signal transceiver, so that the signal transceiver can solve the problems of transmission delay and signal loss in the signal transceiving process of the existing signal transceiver. Specifically, in a case where the first transmitting circuit transmits a first signal and the second receiving circuit receives a second signal, the signal transceiver turns on a path between the interference processing circuit and the first transmitting circuit, so that the interference processing circuit generates an adjusted first signal and cancels the first signal received by the second receiving circuit, thereby reducing or even eliminating the interference of the first signal on the second signal; meanwhile, under the condition that the second sending circuit sends a third signal and the first receiving circuit receives a fourth signal, the signal transceiver conducts a channel between the interference processing circuit and the second sending circuit, so that the interference processing circuit generates an adjusted third signal to be cancelled with the third signal received by the first receiving circuit, and therefore the interference of the third signal on the fourth signal is reduced or even eliminated, and the problems that the transmission of the third signal and the fourth signal is delayed and lost due to the fact that the second receiving circuit is closed when the first sending circuit sends the first signal and the first receiving circuit is closed when the second sending circuit sends the third signal are avoided.

Optionally, in an embodiment of the present invention, the interference processing circuit further includes a switch unit, so that the switch unit can control the target signal adjusting module to be conducted with the first transmitting circuit and the second transmitting circuit.

The target switch unit 232 is used for turning on or off a path between the target signal adjusting module 231 and the first transmitting circuit 211, and/or for turning on or off a path between the target signal adjusting module 231 and the second transmitting circuit 221.

The control circuit 24 is connected to the target switch unit 232, and is configured to send a first control signal and/or a second control signal to the target switch unit 232, where the first control signal is used to control the target switch unit 232 to turn on or off a path between the target signal adjusting module 231 and the first sending circuit 211, and the second control signal is used to control the target switch unit 232 to turn on or off a path between the target signal adjusting module 231 and the second sending circuit 221.

Further optionally, in an embodiment of the present invention, as shown in fig. 6, the target switch unit 232 includes: a first switching unit 232a and a second switching unit 232b, wherein: the first switching unit 232a is connected to the first transmitting circuit 211; the second switching unit 232b is connected to the second transmission circuit 221.

The control circuit 24 is connected to the first switch unit 232a, and configured to send a first control signal to the first switch unit 232a, where the first control signal is used to control the first switch unit 232a to turn on or off a path between the target signal adjusting module 231 and the first sending circuit 211.

The control circuit 24 is connected to the second switch unit 232b, and configured to send a second control signal to the second switch unit 232b, where the second control signal is used to control the second switch unit 232b to turn on or off a path between the target signal adjusting module 231 and the second sending circuit 221.

Further optionally, in an embodiment of the present invention, as shown in fig. 6, the target signal adjusting module 231 includes: a first signal conditioning module 231a and a second signal conditioning module 231b, wherein: the first switch unit 232a is connected to the first signal adjusting module 231a, and is configured to turn on or off a path between the first signal adjusting module 231a and the first transmitting circuit 211; the second switch unit 232b is connected to the second signal adjusting module 231b, and is used for turning on or off a path between the second signal adjusting module 231b and the second transmitting circuit 221.

For example, taking the first level signal as a 4G Tx (transmission) control signal, the second level signal as a 4G Rx (reception) control signal, the third level signal as a 5G Tx control signal, and the fourth level signal as a 5G Rx control signal as an example, the correspondence relationship between the first level signal, the second level signal, the third year level signal, and the fourth level signal and the corresponding control signals is shown in table 1 below.

TABLE 1

For example, referring to table 1 above, taking the 4G Tx control signal as an example, when the 4G Tx control signal is used to instruct to transmit the 4G signal, the corresponding level signal is a high level signal, i.e. 1, and when the 4G Tx control signal is used to instruct not to transmit the 4G signal, the corresponding level signal is a low level signal, i.e. 0.

For example, when the 4G Tx control signal is 0, the 4G Rx control signal is 1, the 5G Tx control signal is 1, and the 5G Rx control signal is 0, the corresponding control signal is 1, that is, the corresponding switch unit is turned on; when the 4G Tx control signal is 1, the 4G Rx control signal is 0, the 5G Tx control signal is 0, and the 5G Rx control signal is 1, the corresponding control signal is 0, i.e., the corresponding switch unit is turned off.

It should be noted that 1 and 0 are merely examples, and other labels may be used instead in practical applications, and the present invention is not limited thereto.

For example, taking the first transceiver circuit as a 4G signal transceiver circuit and the second transceiver circuit as a 5G signal transceiver circuit as an example, the 4G signal transceiver circuit includes a 4G signal receiving circuit and a 4G signal transmitting circuit, and the 5G signal transceiver circuit includes a 5G signal receiving circuit and a 5G signal transmitting circuit, where the 4G signal receiving circuit, the 5G signal receiving circuit, and the 5G signal transmitting circuit share a common antenna, and the 4G signal transmitting circuit includes a 4G transmitting antenna.

The control circuit 316 is connected 307 to a first switch 310 and a second switch, respectively, the first switch 310 is used to turn on or off a path between the first coupler 311 and the first signal adjusting unit 309, and the second switch 307 is used to turn on or off a path between the second coupler 306 and the second signal adjusting unit 308.

In a first example: when the 4G rf transceiver sends a 4G signal and the 5G rf transceiver receives a 5G signal, the control circuit sends a control signal to the first switch to control the first switch to turn on, i.e., control the first switch to turn on a path between the first coupler and the first signal adjusting unit, so that the 4G signal can be coupled to the first signal adjusting unit through the first coupler, and the first signal adjusting unit adjusts the 4G signal, so that the adjusted 4G signal can cancel the 4G signal in the 5G signal receiving circuit (i.e., the 4G signal coupled to the common antenna through the 4G sending antenna), thereby reducing or even eliminating the interference of the 4G signal on the 5G signal.

In a second example: when the 4G radio frequency transceiver sends out the 4G signal and the 5G radio frequency transceiver does not receive the 5G signal, the control circuit sends a control signal to the first switch to control the first switch to be closed, namely, the first switch is controlled to close a path between the first coupler and the first signal adjusting unit, so that the waste of electric quantity is avoided.

In a third example: when the 5G rf transceiver sends a 5G signal and the 4G rf transceiver receives a 4G signal, the control circuit sends a control signal to the second switch to control the second switch to open, that is, the second switch is controlled to turn on a path between the second coupler and the second signal adjusting unit, so that the 5G signal can be coupled to the second signal adjusting unit through the second coupler, and the second signal adjusting unit adjusts the signal, so that the adjusted 5G signal can be cancelled with the 5G signal in the 4G signal receiving circuit (that is, the 5G signal sent by the 5G signal sending circuit is coupled to the 5G signal of the 4G signal receiving circuit through the circulator), and interference of the 5G signal on the 4G signal is reduced or even eliminated.

In a fourth example: when the 5G radio frequency transceiver sends the 5G signal and the 4G radio frequency transceiver does not receive the 4G signal, the control circuit sends a control signal to the second switch to control the second switch to be closed, namely, the second switch is controlled to close a path between the second coupler and the second signal adjusting unit, so that electric quantity waste is avoided.
