Description

Since 4G LTE and 5GNR operate simultaneously, there is a problem in that signals interfere with each other. For example, the signal transmission frequency used for data transmission based on 4G LTE may generate a second harmonic, which may interfere with the signal transmission frequency for data reception based on 5 GNR. At present, in order to solve the problem of signal interference in a non-independent architecture, a time-frequency scheduling mode can be adopted, namely, interference frequency is avoided. The base station can avoid the frequency band generating interference by scheduling and distributing the frequency spectrum resources, even if the signal transmitting frequency adopted when the data transmission is performed based on the 4G LTE is far away from the signal transmitting frequency when the data reception is performed based on the 5GNR, the second harmonic generated by the signal transmitting frequency adopted when the data transmission is performed based on the 4G LTE is avoided, and the data reception is caused to the 5 GNR.

However, due to the diversity of frequency band combinations, the method for scheduling by using time-frequency has the problem of higher algorithm complexity, the existing spectrum resources are limited, the signal transmitting frequency adopted in the process of data transmission based on 4G LTE is difficult to be far away from the signal transmitting frequency in the process of data reception based on 5G NR, and the feasibility is poor. Therefore, based on the above-mentioned manner of avoiding interference frequencies, the problem of signal interference in the non-independent architecture cannot be effectively solved.

Detailed Description

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

In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, shall fall within the scope of the invention.

Example 1

As shown in fig. 1, an embodiment of the present invention provides a method for transmitting information, where an execution 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, a tablet computer, or the like, and the electronic device may perform information transmission based on two information transmission modes at the same time. The method specifically comprises the following steps:

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

The network side device may be a device that connects to an electronic device and allocates a channel to the electronic device, and the electronic device may perform information transmission 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 the first information transmission mode and channel information of the 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 equipment through the channel 1, and the channel information of the second information transmission mode can be: the information is transmitted through the channel 2 and the network side equipment, the network modes used by the channel 1 and the channel 2 are different, the frequency band occupied by the network mode adopted by the channel 1 can be the frequency band occupied by the 4G LTE network mode, such as 1710MHz-1785MHz, the frequency band occupied by the network mode adopted by the channel 2 can be the frequency band occupied by 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 transmits the information based on the two information transmission modes, the channel information of the first information transmission mode can interfere the channel information of the second information transmission mode.

In implementation, with the continuous development of mobile communication technology, mobile communication has started to develop into the fifth generation mobile communication (5G) era, in order to reduce the deployment cost of the 5G network, the deployment of the 5G network may be performed in an existing network facility, that is, the electronic device may 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 in that signals interfere with each other. For example, the signal transmission frequency used for data transmission based on 4G LTE may generate a second harmonic, which may interfere with the signal transmission frequency for data reception based on 5 GNR. At present, in order to solve the problem of signal interference in a non-independent architecture, a time-frequency scheduling mode can be adopted, namely, interference frequency is avoided. The base station can avoid the frequency band generating interference by scheduling and distributing the frequency spectrum resources, even if the signal transmitting frequency adopted when the data transmission is performed based on the 4G LTE is far away from the signal transmitting frequency when the data reception is performed based on the 5GNR, the second harmonic generated by the signal transmitting frequency adopted when the data transmission is performed based on the 4G LTE is avoided, and the data reception is caused to the 5 GNR.

However, due to the diversity of frequency band combinations, the method for time-frequency scheduling has the problems of higher algorithm complexity, limited existing spectrum resources, difficulty in keeping the signal transmission frequency adopted in the data transmission based on 4G LTE away from the signal transmission frequency in the data reception based on 5G NR, and poor feasibility. Therefore, based on the above-mentioned manner of avoiding interference frequencies, the problem of signal interference in the non-independent architecture cannot be effectively solved.

In addition, besides the above-mentioned problem of signal interference by avoiding the interference frequency, there is a solution that the problem of signal interference caused by the reception of information based on 5GNR by the transmission of information based on 4G LTE is avoided by adding a harmonic suppressor or increasing the isolation between antennas of two transmission modes 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 is transmitted based on 4G, and large difficulty in antenna design.

Therefore, the embodiment of the invention provides a technical scheme capable of solving the problems, which specifically comprises the following steps:

As shown in fig. 2, a radio frequency transceiver may be configured within the electronic device, and the radio frequency transceiver may be coupled 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-convert and 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, powerAmplifier) and a second power Amplifier 2 (e.g., a low noise Amplifier LNA). In the first sub-circuit, a switch connected to the second power amplifier may be connected to the control circuit 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 mode, 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 mode 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 be connected 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 for transmitting information and receive a reception signal for receiving information, so as to transmit information based on the first information transmission scheme. The second sub-circuit may include a first power amplifier, a duplexer, an antenna switch, a coupler, a first antenna, and other devices, where the duplexer may isolate a transmit signal and a receive signal that perform information transmission and reception based on the first information transmission mode, so as to ensure that information may be received and transmitted based on the first information transmission mode at the same time.

When the electronic device is located in the signal coverage of the network side device (such as a base station), the electronic device can be connected with the network side device and registered in the network side device, the network side device can allocate a channel for information transmission to the electronic device, then the network side device can send the allocated channel information to the electronic device, and the electronic device can receive the channel information sent by the network side device.

For example, the electronic device is located in the signal coverage area of the base station 1 and is connected with the base station 1 through the internally configured dual antennas, at this time, the electronic device can realize information transmission with the base station 1 based on a non-independent architecture, and the base station 1 can allocate a corresponding channel to the electronic device. For example, the electronic device may perform information transmission based on the first information transmission method on the channel 1, and perform information transmission based on the second information transmission method on the channel 2, where the channel 1 and the 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 method is channel 1, and the channel information of the second information transmission method is channel 2.

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

The target notch network may be any notch network that is matched to the channel information and is used for filtering the interference signal.

In an implementation, after receiving channel information from the network side device, interference detection may be performed on the channel information of the first information transmission mode and the channel information of the second information transmission mode, so as to determine whether signal interference exists in the channel information of the two information transmission modes.

For example, the received channel information is: the channel information of the first information transmission scheme is channel 1, the channel information of the second information transmission scheme is channel 2, as shown in the following table 1, the signal transmission power range when information transmission is performed based on the first information transmission scheme corresponding to channel 1 is 1710MHz-1785MHz, the range of the corresponding generated second harmonic is 3420MHz-3570MHz, and the signal transmission power range when information reception is performed based on the second information transmission scheme corresponding to channel 2 is 3300MHz-3800MHz. The second harmonic generated by the signal transmitting frequency corresponding to the channel 1 when the information is transmitted based on the first information transmission mode will interfere with the signal transmitting frequency corresponding to the channel 2 when the information is received based on the second information transmission mode.

TABLE 1

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

The method for determining that the channel information of the first information transmission mode and the channel information of the second information transmission mode have interference and the method for acquiring the target notch network are optional and practical methods, and in practical application, there may be multiple interference detection methods and multiple methods for acquiring the target notch network, which may be different according to different practical application scenarios, and the embodiment of the present invention is not limited in particular.

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 the information is transmitted based on the first information transmission mode can be filtered based on the target notch network, the signal transmitting frequency is not influenced when the information is transmitted based on the second information transmission mode, and meanwhile the interference of the interference signal generated when the information is transmitted based on the first information transmission mode to the second information transmission mode can be reduced.

As shown in fig. 2, two accessible circuits (such as a circuit 1 and a circuit 2) may be installed in the second sub-circuit corresponding to the first information transmission mode, where 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 electronic device can detect the received channel information, and under the condition that signal interference between the channel information of the first information transmission mode and the channel information of the second information transmission mode is not detected, the second sub-circuit can be connected to the circuit 3, i.e. the circuit without generating a notch network, so as to perform normal information transmission based on the first information transmission mode.

When the channel information of the first information transmission mode and the channel information of the second information transmission mode have interference, a target notch network matched with the channel information can be acquired based on the channel information. If it is determined that, when information is transmitted based on the first information transmission mode based on the channel information, an interference signal 1 that interferes with information transmission of the second information transmission mode is generated, the corresponding target notch network may be a notch network for filtering the interference signal 1, that is, the second sub-circuit may be switched from the circuit 3 to the circuit 1 at this time to filter the interference signal 1. Because the circuit is switched in the second sub-circuit 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 meanwhile, the interference on 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 sub-circuit may be switched from circuit 1 to circuit 3, i.e. into a circuit which does not generate a notch network. When it is detected that the electronic device is connected to the network side device (e.g. the base station 2) again, the channel information received from the base station 2 may be detected, and when it is detected that the channel information of the first information transmission mode and the channel information of the second information transmission mode interfere, a target notch network (e.g. a notch network for filtering the interfering signal 2) that is matched with the channel information at this time may be obtained, and then, according to the target notch network, the second sub-circuit is switched to a corresponding circuit (e.g. from the circuit 1 or the circuit 2 to the circuit 2 corresponding to the target notch network for generating the filtering of the interfering signal 2).

Or, according to the channel information, it is detected that the electronic device is in a state of using only the first information transmission mode for information transmission and not using the second information transmission mode for information transmission, the second sub-circuit may be switched to the circuit 3, that is, no notch network is generated, so that normal information transmission is performed based on the first information transmission mode. Likewise, if no signal interference is detected in both information transmission modes, the second sub-circuit may also be switched to circuit 3.

The embodiment of the invention provides an information transmission method, which is characterized in that channel information sent by network side equipment is received, 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 a target notch network matched with the channel information is obtained under the condition that signal interference exists between the channel information of the first information transmission mode and the channel information of the second information transmission mode, and finally a signal based on the first information transmission mode is filtered based on the target notch network. Therefore, the interference of the second information transmission mode can be realized only by filtering the interference signals generated during the information transmission of the first information transmission mode, and the signal transmitting frequencies of the two transmission modes are not required to be distributed and scheduled again, so that the algorithm complexity is reduced, the practicability is higher, and the problem of mutual interference of signals in a non-independent framework can be solved.

Example two

As shown in fig. 4, an embodiment of the present invention provides a method for transmitting information, where an execution 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, a tablet computer, or the like, and the electronic device may perform information transmission based on two information transmission modes at the same time. The method specifically comprises the following steps:

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

The specific processing procedure of S402 may be referred to the relevant content in S102 in the first embodiment, and will not be described herein.

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

In implementations, interference harmonic multiples can be determined based on channel information. For example, if the signal transmission frequency used for the channel 1 corresponding to the first information transmission scheme is 1710MHz and the signal transmission frequency used for the channel 2 corresponding to the second information transmission scheme is 3420MHz, the corresponding interference harmonic is 2 times (i.e., 3420/1710=2).

In practical applications, the processing manner of S404 may be varied, and an alternative implementation manner is provided below, which may be specifically referred to as the following steps one to two.

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

In an 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 relation	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 achievable 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 particularly limited in the embodiment of the present invention.

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

In practice, after determining the channel combination relationship, the corresponding interference harmonic times may be determined according to the channel combination relationship, e.g., as shown in table 3, different channel combination relationships may correspond to the same or different interference harmonic times.

TABLE 3 Table 3

Interference harmonic order	Channel combination relation
		2 times of	Combination relation 1, combination relation 2
3 times of	Combination relation 3

In practical applications, the interference harmonic times may be multiple, and may be 1 time, 4 times, or the like in addition to 2 times and 3 times in the above table 3, and the corresponding channel combination relationships may also be multiple, where the corresponding relationship between the interference harmonic times and the channel combination relationships provided in the above table 3 is an optional and achievable corresponding relationship, and in addition, there may be multiple corresponding relationships between the interference harmonic times and the channel combination relationships, which may be different according to different practical application scenarios, and the embodiment of the present invention is not limited specifically.

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

In practice, different interference harmonic orders may correspond to different target notch networks, which may be notch networks for filtering interference signals of the respective interference harmonic orders. If the interference harmonic order 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 mode and the channel information of the second information transmission mode, the signal transmitting power of the first signal transmission mode is detected to match with a preset power threshold, and when it is detected that the signal transmitting power is greater than the preset power threshold, a target notch network matched with the channel information is acquired.

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

In an 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 may be continued based on the signal transmission power of the first information transmission mode.

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

The specific processing procedure of S410 may be referred to the related content in S106 in the first embodiment, and will not be described herein.

In practical applications, the processing manner of S410 may be varied, and an alternative implementation manner is provided below, which may be specifically referred to as the following steps one to two.

Step one, a target voltage corresponding to the interference harmonic order is determined based on the interference harmonic order.

In practice, the target voltage corresponding to the interference harmonic order may be determined according to a preset order voltage relationship. For example, the corresponding target voltage may be 0.5V if the interference harmonic is 2 times and 1V if the interference harmonic is 3 times. The specific target voltage value 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 notch network to be connected into 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 notch network, and the preset control switch can be a single-pole multi-throw switch.

In implementation, as shown in fig. 5, in the second sub-circuit (i.e., the circuit of the first information transmission mode), a preset control switch may be set, so that the circuit corresponding to the target notch network is connected to the second sub-circuit.

In addition, the harmonic interference identification signal can be determined based on the interference harmonic times, 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 order, 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 circuit formed by a plurality of sets of capacitors (C) of preset capacitance values and inductors (L) of preset sense, and to the idle ports.

When the target voltage is received, a preset control switch can be controlled according to the target voltage, and a circuit corresponding to the target notch network is connected to the second sub-circuit. For example, as shown in FIG. 6, the circuit 1 is a capacitor C ₀ And inductance L ₀ Formed as a circuit for generating a notch network for filtering the second harmonic, the circuit 2 being a capacitor C ₁ And inductance L ₁ Is configured to generate a notch network for filtering the third harmonic, and if the target voltage is 0.5V, a preset control switch can be controlled to be connected to the circuit 1 to filter the second harmonic.

In addition, if signal interference between the first information transmission mode and the second information transmission mode is not detected, the target voltage may be set to 2V, and the preset control switch is controlled to be connected to the idle port, so that normal information transmission is performed based on the first information transmission mode.

In practical application, as shown in fig. 5, the baseband processor may receive channel information from a network side device (such as a base station) and send the channel information to the modem, the modem may modulate and demodulate the channel information, determine 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 is detected between the first information transmission mode and the second information transmission mode, determine a corresponding interference harmonic order according to the channel information, determine a harmonic interference identification signal according to the interference harmonic order, and then send the harmonic interference identification signal to the baseband processor, determine a target voltage according to the harmonic interference identification signal, and then control a preset control switch according to the target voltage, so that a circuit of the target notch network is connected to the second sub-circuit.
