Description

Information transmission method and device and electronic equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for transmitting information, and an electronic device.

Background

With the continuous development of mobile communication technology, the current mobile communication has started to develop towards the fifth generation mobile communication (5G) era, and in order to reduce the deployment cost of the 5G network, the 5G network can be deployed in the existing network facilities, i.e. the electronic device can connect the 5G network and the 4G network based on a non-independent architecture.

Since 4G LTE and 5GNR operate simultaneously, there is a problem of signal interference with each other. For example, a signal transmission frequency used for data transmission based on 4G LTE generates a second harmonic, and the second harmonic interferes with a signal transmission frequency used for data reception based on 5 GNR. At present, in order to solve the problem of mutual interference of signals in a non-independent architecture, a time-frequency scheduling mode, namely, interference frequency avoidance, can be adopted. The base station can avoid the frequency band generating interference by scheduling and allocating the frequency spectrum resources, even if the signal transmitting frequency adopted when the data is transmitted based on the 4G LTE is far away from the signal transmitting frequency when the data is received based on the 5GNR, thereby avoiding the interference to the data receiving based on the 5GNR caused by the second harmonic generated by the signal transmitting frequency adopted when the data is transmitted based on the 4G LTE.

However, due to the diversity of frequency band combinations, the above method using time-frequency scheduling has a problem of high algorithm complexity, and the existing spectrum resources are limited, and it is difficult to separate the signal transmission frequency used when data transmission is performed based on 4G LTE from the signal transmission frequency used when data reception is performed based on 5G NR, and the implementability is poor. Therefore, the problem of mutual interference of signals in a non-independent architecture cannot be effectively solved based on the above interference frequency avoiding mode.

Detailed Description

The embodiment of the invention provides an information transmission method and device and electronic equipment.

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. 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.

Example one

As shown in fig. 1, an execution main body of the method may be an electronic device that performs information transmission based on a non-independent architecture, where the electronic device may be a device such as a personal computer, or a mobile electronic device such as a mobile phone and a tablet computer, and the electronic device may perform information transmission based on two information transmission modes at the same time. The method may specifically comprise the steps of:

in S102, the channel information transmitted by the network side device is received.

The network-side device may be a device that is connected to the electronic device and allocates a channel to the electronic device, and the electronic device may transmit information with the network-side device based on the allocated channel, for example, the network-side device may be a base station. The channel information may include channel information of a first information transmission mode and channel information of a second information transmission mode, and a frequency band occupied by a network system used by the first information transmission mode may be lower than a frequency band occupied by a network system used by the second information transmission mode, for example, the channel information of the first information transmission mode may be: the information transmission is performed with the network side device through the channel 1, and the channel information of the second information transmission mode may be: information is transmitted through the channel 2 and the network side equipment, the channel 1 and the channel 2 have different network systems, the frequency band occupied by the network system adopted by the channel 1 can be the frequency band occupied under the 4G LTE network system, such as 1710MHz-1785MHz, the frequency band occupied by the network system adopted by the channel 2 can be the frequency band occupied under 5GNR, such as 3300MHz-3800MHz, the signal transmitting power of the first information transmission mode can be lower than the signal transmitting power of the second information transmission mode, and when the electronic equipment simultaneously performs information transmission based on the two information transmission modes, the channel information of the first information transmission mode can generate interference on the channel information of the second information transmission mode.

In implementation, with the continuous development of mobile communication technology, the current mobile communication has started to develop towards the fifth generation mobile communication (5G) era, and in order to reduce the deployment cost of the 5G network, the deployment of the 5G network can be performed in the existing network infrastructure, that is, the electronic device can connect the 5G network and the 4G network based on a non-independent architecture. Since 4G LTE and 5GNR operate simultaneously, there is a problem of signal interference with each other. For example, a signal transmission frequency used for data transmission based on 4G LTE generates a second harmonic, and the second harmonic interferes with a signal transmission frequency used for data reception based on 5 GNR. At present, in order to solve the problem of mutual interference of signals in a non-independent architecture, a time-frequency scheduling mode, namely, interference frequency avoidance, can be adopted. The base station can avoid the frequency band generating interference by scheduling and allocating the frequency spectrum resources, even if the signal transmitting frequency adopted when the data is transmitted based on the 4G LTE is far away from the signal transmitting frequency when the data is received based on the 5GNR, thereby avoiding the interference to the data receiving based on the 5GNR caused by the second harmonic generated by the signal transmitting frequency adopted when the data is transmitted based on the 4G LTE.

However, due to the diversity of frequency band combinations, the time-frequency scheduling method has the problem of high algorithm complexity, and the existing spectrum resources are limited, so that it is difficult to separate the signal transmission frequency used in data transmission based on 4G LTE from the signal transmission frequency used in data reception based on 5G NR, and the implementability is poor. Therefore, the problem of mutual interference of signals in a non-independent architecture cannot be effectively solved based on the above interference frequency avoiding mode.

In addition to the above-mentioned problem of signal interference by avoiding the interference frequency, there is a solution to avoid the problem of signal interference caused by the transmission of information based on 4G LTE and the reception of information based on 5GNR by adding a harmonic suppressor or increasing the isolation between antennas of two transmission methods in an electronic device.

However, the above solution also has the problems of large insertion loss of the 4G LTE path, poor transmission performance when information transmission is performed based on 4G, and large difficulty in antenna design.

Therefore, an embodiment of the present invention provides a technical solution capable of solving the above problems, which may specifically include the following:

as shown in fig. 2, a radio frequency transceiver may be disposed in the electronic device, and the radio frequency transceiver may be connected to two sub-circuits (which may be referred to as a first sub-circuit and a second sub-circuit), and may be used to up-down convert transmitted and received signals.

The first sub-circuit may be connected in series with a second power amplifier, a switch, a filter, an antenna switch, and a second antenna, and may transmit a transmission signal for transmitting information and a reception signal for receiving information based on the circuit to implement transmission of information based on a second information transmission manner, where the second power amplifier may include a second power amplifier 1 (e.g., a power amplifier PA, a PowerAmplifier) and a second power amplifier 2 (e.g., a low noise amplifier LNA, a lownoise amplifier). In the first sub-circuit, a switch connected to the second power amplifier may control the circuit to be connected to the second power amplifier corresponding to the signal according to the received signal. For example, when the radio frequency transceiver transmits a transmission signal for information transmission based on the second information transmission scheme, the switch may be connected to the second power amplifier 1 to amplify the transmission signal and transmit the amplified transmission signal to the base station through the filter and the second antenna. Alternatively, when receiving a reception signal based on the second information transmission scheme from the base station, the reception signal may be transmitted to the switch through the filter, and then the switch may control the circuit to connect with the second power amplifier 2 to transmit the reception signal to the radio frequency transceiver.

Similarly, the second sub-circuit may be configured to transmit a transmission signal of the transmission information and a reception signal of the reception information, so as to transmit information based on the first information transmission method. The second sub-circuit may include devices such as a first power amplifier, a duplexer, an antenna switch, a coupler, and a first antenna, where the duplexer may isolate a transmitting signal and a receiving signal for transmitting and receiving information based on the first information transmission method, so as to ensure that information can be simultaneously received and transmitted based on the first information transmission method.

When the electronic device is located within a signal coverage area of a network-side device (e.g., a base station), the electronic device may connect with the network-side device and register with the network-side device, the network-side device may allocate a channel for information transmission to the electronic device, and then the network-side device may send the allocated channel information to the electronic device, and the electronic device may receive the channel information sent from the network-side device.

For example, the electronic device is located within the signal coverage of the base station 1 and connected to the base station 1 through the internally configured dual antenna, at this time, the electronic device may implement information transmission with the base station 1 based on a non-independent architecture, and the base station 1 may allocate a corresponding channel to the electronic device. For example, the electronic device may perform information transmission based on a first information transmission method on channel 1, and perform information transmission based on a second information transmission method on channel 2, where channel 1 and channel 2 are channels with different frequencies. The electronic device may receive channel information from the base station 1, and the received signal information may be: the channel information of the first information transmission mode is channel 1, and the channel information of the second information transmission mode is channel 2.

In S104, when there is signal interference between the channel information of the first information transmission scheme and the channel information of the second information transmission scheme, a target notch network matching the channel information is acquired.

The target notch network may be any notch network matched with the channel information for filtering the interference signal.

In implementation, after receiving the channel information from the network side device, interference detection may be performed on the channel information of the first information transmission method and the channel information of the second information transmission method to determine whether there is signal interference in the channel information of the two information transmission methods.

For example, the received channel information is: the channel information of the first information transmission mode is channel 1, the channel information of the second information transmission mode is channel 2, as shown in table 1 below, the signal transmission power range when information transmission is performed based on the first information transmission mode corresponding to channel 1 is 1710MHz-1785MHz, the range of the correspondingly generated second harmonic is 3420MHz-3570MHz, and the signal transmission power range when information reception is performed based on the second information transmission mode corresponding to channel 2 is 3300MHz-3800 MHz. The second harmonic generated corresponding to the signal transmitting frequency when the information is transmitted based on the first information transmission method corresponding to the channel 1 may cause interference to the signal transmitting frequency when the information is received based on the second information transmission method corresponding to the channel 2.

TABLE 1

In the case that there is signal interference between the channel information of the first information transmission method and the channel information of the second information transmission method, a target notch network matched with the channel information may be acquired based on the channel information. For example, as shown in table 1, if the second harmonic generated corresponding to the signal transmission power when information is transmitted based on the first information transmission scheme corresponding to channel 1 causes signal interference with the signal transmission power when information is received based on the second information transmission scheme corresponding to channel 2, the target notch network may be a notch network for filtering the second harmonic generated by the signal transmission power when information is transmitted based on the first information transmission scheme.

The method for determining that the channel information of the first information transmission mode and the channel information of the second information transmission mode interfere with each other and the method for acquiring the target notch network are optional and realizable methods, and in practical application, there may be a plurality of interference detection methods and a plurality of methods for acquiring the target notch network, which may be different according to different practical application scenarios, and this is not specifically limited in the embodiment of the present invention.

In S106, a signal for information transmission based on the first information transmission scheme is filtered based on the target notch network.

In implementation, the interference signal generated when information is transmitted based on the first information transmission mode may be filtered based on the target notch network, without affecting the signal transmission frequency when information is transmitted based on the second information transmission mode, and the interference caused by the interference signal generated when information is transmitted based on the first information transmission mode to the second information transmission mode may be reduced.

As shown in fig. 2, two accessible circuits (e.g., circuit 1 and circuit 2) may be installed in the second sub-circuit corresponding to the first information transmission mode, the circuit 1 may generate a notch network for filtering the interference signal 1, and the circuit 2 may generate a notch network for filtering the interference signal 2. When the electronic device is connected to the base station and receives the channel information sent by the base station, the received channel information may be detected, and when it is not detected that the channel information of the first information transmission mode and the channel information of the second information transmission mode have signal interference, the second sub-circuit may be accessed to the circuit 3, that is, a circuit of the notch network is not generated, so as to perform normal information transmission based on the first information transmission mode.

In the case that the channel information of the first information transmission method and the channel information of the second information transmission method have interference, a target notch network matched with the channel information can be obtained based on the channel information. For example, if it can be determined based on the channel information that an interfering signal 1 interfering with the information transmission of the second information transmission scheme is generated when the information transmission is performed based on the first information transmission scheme, the corresponding target notch network may be a notch network for filtering the interfering signal 1, i.e. the second sub-circuit may be switched from the circuit 3 to the circuit 1 to filter the interfering signal 1. Because the circuit is switched in the second subcircuit to generate the corresponding target notch network, the target notch network does not generate a filtering effect on the signal transmitting frequency of the second information transmission mode, and simultaneously, the interference caused to the second information transmission mode can be reduced.

Furthermore, when it is detected that the electronic device is disconnected from the base station, the second subcircuit may be switched from circuit 1 to circuit 3, i.e. into a circuit that does not generate a notch network. When the electronic device is detected to be connected to a network-side device (e.g., the base station 2) again, the received channel information from the base station 2 may be detected, and when it is detected that the channel information of the first information transmission method interferes with the channel information of the second information transmission method, a target notch network (e.g., a notch network for filtering the interference signal 2) matching the channel information at this time may be obtained, and then the second sub-circuit may be switched to a corresponding circuit according to the target notch network (e.g., from the circuit 1 or the circuit 2 to the circuit 2 corresponding to the target notch network for generating the filtering the interference signal 2).

Alternatively, the second sub-circuit may be switched to the circuit 3, i.e. without any notch network, to perform normal information transmission based on the first information transmission mode, according to the channel information detecting that the electronic device is in a state of using only the first information transmission mode for information transmission, but not using the second information transmission mode for information transmission. Similarly, if it is detected that there is no signal interference in both information transmission modes, the second sub-circuit may be switched to the circuit 3.

The embodiment of the invention provides an information transmission method, which comprises the steps of receiving channel information sent by network side equipment, wherein the channel information comprises channel information of a first information transmission mode and channel information of a second information transmission mode, the frequency band occupied by a network system used by the first information transmission mode is lower than the frequency band occupied by a network system used by the second information transmission mode, then acquiring a target notch network matched with the channel information under the condition that the channel information of the first information transmission mode and the channel information of the second information transmission mode have signal interference, and finally filtering signals for information transmission based on the first information transmission mode based on the target notch network. Therefore, interference on the second information transmission mode can be realized only by filtering interference signals generated by the first information transmission mode during information transmission, and signal transmitting frequencies of the two transmission modes do not need to be distributed and scheduled again, so that the algorithm complexity is reduced, the practicability is high, and the problem of mutual interference of signals in a non-independent architecture can be solved.

Example two

As shown in fig. 4, an execution main body of the method may be an electronic device that performs information transmission based on a non-independent architecture, where the electronic device may be a device such as a personal computer, or a mobile electronic device such as a mobile phone and a tablet computer, and the electronic device may perform information transmission based on two information transmission modes at the same time. The method may specifically comprise the steps of:

in S402, the channel information transmitted by the network side device is received.

For the specific processing procedure of S402, reference may be made to relevant contents in S102 in the first embodiment, which is not described herein again.

In S404, an interference harmonic multiple corresponding to a channel relationship between the first information transmission scheme and the second information transmission scheme is determined based on the channel information.

In an implementation, the interference harmonic multiples may be determined based on channel information. For example, if the signal transmission frequency used by the channel 1 corresponding to the first information transmission method is 1710MHz, and the signal transmission frequency used by the channel 2 corresponding to the second information transmission method is 3420MHz, the corresponding interference harmonic is multiplied by 2 (i.e., 3420/1710 is 2).

In practical applications, the processing manner of S404 may be various, and an alternative implementation manner is provided below, which may specifically refer to the following processing from step one to step two.

Step one, determining a channel combination relation between a first information transmission mode and a second information transmission mode based on a preset channel combination relation.

In implementation, the channel combination relationship between the first information transmission mode and the second information transmission mode may be determined based on the channel information of the first information transmission mode, the channel information of the second information transmission mode, and a preset channel combination relationship. As shown in table 2, if the information transmission of the first information transmission method is performed based on the channel 1, and the information transmission of the second information transmission method is performed based on the channel 4, the channel combination relationship between the first information transmission method and the second information transmission method is the combination relationship 1.

TABLE 2

Channel combination relationship	Channel information of first information transmission mode	Channel information of second information transmission mode
			Combination relation
1	Channel 1	Channel 4
			Combination relation 2	Channel 1	Channel 5
Combination relation 2	Channel 2	Channel 5
			Combination relation 3	Channel 3	Channel 6

The preset channel combination relationship is an optional and realizable channel combination relationship, and the specific setting of the preset channel combination relationship may be different according to different practical application scenarios, which is not specifically limited in the embodiment of the present invention.

And step two, determining corresponding interference harmonic multiples based on the channel combination relation between the first information transmission mode and the second information transmission mode.

In implementation, after the channel combination relationship is determined, the corresponding interference harmonic multiples may be determined according to the channel combination relationship, for example, as shown in table 3, different channel combination relationships may correspond to the same or different interference harmonic multiples.

TABLE 3

Harmonic order of interference	Channel combination relationship
		2 times of	Combination relation 1 and combination relation 2
3 times of	Combination relation 3

In practical application, the interference harmonic multiples may be multiple, and may be 2 times, 3 times, 1 time, 4 times, and the like in the above table 3, and the corresponding channel combination relationship may also be multiple, and the correspondence between the interference harmonic multiples and the channel combination relationship provided in the above table 3 is a selectable and realizable correspondence, and in addition, may also be multiple correspondences between the interference harmonic multiples and the channel combination relationship, which may be different according to different practical application scenarios, and this is not specifically limited in the embodiment of the present invention.

In S406, a target notch network corresponding to the interference harmonic multiple is determined based on the interference harmonic multiple.

In an implementation, different interference harmonic multiples may correspond to different target notch networks, and the target notch networks may be notch networks for filtering interference signals of the corresponding interference harmonic multiples. If the interference harmonic is 2 times, the target notch network may be a notch network for filtering the second harmonic.

In S408, when there is signal interference between the channel information of the first information transmission method and the channel information of the second information transmission method, matching detection is performed on the signal transmission power of the first signal transmission method and a preset power threshold, and when it is detected that the signal transmission power is greater than the preset power threshold, a target notch network matched with the channel information is obtained.

The preset power threshold may be any power, such as 1750MHz or 1785MHz, used for determining whether interference is caused to information transceiving based on the second information transmission mode when target information is transmitted based on the first information transmission mode.

In implementation, if it is detected that the signal transmission power of the first information transmission mode is not greater than the preset power threshold, information transmission based on the signal transmission power of the first information transmission mode may be continued.

In S410, a signal for information transmission based on the first information transmission scheme is filtered based on the target notch network.

For the specific processing procedure of S410, reference may be made to relevant contents in S106 in the first embodiment, which is not described herein again.

In practical applications, the processing manner of S410 may be various, and an alternative implementation manner is provided below, which may specifically refer to the following step one to step two.

Step one, determining a target voltage corresponding to the interference harmonic multiple based on the interference harmonic multiple.

In implementation, the target voltage corresponding to the harmonic order of the interference may be determined according to a preset voltage order relationship. For example, if the interference harmonic is multiplied by 2 times, the corresponding target voltage may be 0.5V, and if the interference harmonic is multiplied by 3 times, the corresponding target voltage may be 1V. The specific value of the target voltage may be set according to an actual application scenario, which is not specifically limited in the embodiment of the present invention.

And step two, controlling a preset control switch based on the target voltage so as to enable a circuit corresponding to the target trap network to be connected to a circuit of the first information transmission mode.

The preset control switch can be used for controlling the circuit access state corresponding to the target trap network, and the preset control switch can be a single-pole multi-throw switch.

In an implementation, as shown in fig. 5, a preset control switch may be disposed in the second sub-circuit (i.e., the circuit of the first information transmission mode) for enabling the circuit corresponding to the target notch network to access the second sub-circuit.

In addition, the harmonic interference identification signal can be determined based on the interference harmonic multiple, and the target voltage can be determined based on the harmonic interference identification signal.

As shown in fig. 5, the modem may determine a harmonic interference identification signal based on the interference harmonic multiple, and the baseband processor may determine a target voltage based on the harmonic interference identification signal to control the preset control switch when transmitting the harmonic interference identification signal to the baseband processor.

As shown in fig. 6, the preset control switch may be connected to a plurality of sets of circuits formed by a capacitor (C) with a preset capacitance value and an inductor (L) with a preset sensing, and the idle port.

When the target voltage is received, the voltage of the target voltage is adjustedAnd controlling a preset control switch according to the target voltage, and connecting a circuit corresponding to the target trap network into the second sub-circuit. For example, as shown in FIG. 6, the circuit 1 is a capacitor C₀And an inductance L₀The circuit being configured to generate a trap network for filtering the second harmonic, the circuit 2 being a capacitor C₁And an inductance L₁Configured to generate a notch network for filtering the third harmonic, if the target voltage is 0.5V, the preset control switch may be controlled to be connected to the circuit 1 to filter the second harmonic.

In addition, if no signal interference between the first information transmission mode and the second information transmission mode is detected, the target voltage can be set to be 2V, and the preset control switch is controlled to be connected to the idle port, so that normal information transmission can be carried out based on the first information transmission mode.

In practical applications, as shown in fig. 5, the baseband processor may receive channel information from a network side device (e.g., a base station), and sending the channel information to a modem, wherein the modem can modulate and demodulate the channel information, and judge whether signal interference exists between the first information transmission mode and the second information transmission mode based on the demodulated channel information, if signal interference between the first information transmission mode and the second information transmission mode is detected, determining the corresponding interference harmonic multiple according to the channel information, and determining a harmonic interference identification signal according to the interference harmonic multiple, then the harmonic interference identification signal is sent to a baseband processor, the baseband processor determines a target voltage according to the harmonic interference identification signal, and then, controlling a preset control switch according to the target voltage so as to enable the circuit of the target trap network to be connected to the second subcircuit.
