1) IDC Interference: Due to the increasing need for data to be connected to multiple wireless networks anytime, anywhere, modern devices are designed to support different Radio Access Technologies (RATs). These devices, such as mobile phones, tablets and various other communication modules, can support different cellular and non-cellular communication standards at the same time; due to the small size of these devices, the transceiver modules of different wireless technologies are placed next to each other.

9) ZigBee: It is a new type of wireless communication technology, suitable for a series of electronic components and devices with short transmission range and low data transmission rate;

10) ISM frequency band: it is the frequency band of Industrial Scientific Medical (ISM); among them, 2.4GHz is the common ISM frequency band of all countries; wireless LAN (IEEE 802.11b/IEEE 802.11g), Bluetooth, ZigBee and other wireless networks , can work in the 2.4GHz frequency band.

At present, with the continuous evolution of communication technology, a variety of different wireless communication systems are integrated into communication devices such as mobile phones, such as: new air interface communication subsystem (NR or 5G), long-term evolution technology subsystem (LTE or 4G), wireless Local Area Network Subsystem (Wi-Fi or WLAN), Bluetooth Subsystem (BT), Near Field Communication Subsystem (NFC), Global Navigation Satellite Subsystem (GNSS), Authorized Spectrum Assisted Access Subsystem (LAA), Zifeng Communication Subsystem (Zigbee). When different wireless communication subsystems work at the same time, the IDC interference problem in the communication equipment will occur between wireless communication subsystems deployed in adjacent frequency bands. Exemplarily, as shown in Figure 1: User Equipment (User Equipment, UE) integrates NR, LTE, Wi-Fi, BT and GNSS communication subsystems. When the Wi-Fi and NR subsystems work at the same time, if the operating frequencies or frequency bands of Wi-Fi and NR/LTE are close, the transmission of Wi-Fi will interfere with the reception of NR/LTE, otherwise the transmission of NR/LTE It will also cause interference to Wi-Fi reception; for example, in Figure 1, there is IDC interference between Wi-Fi and NR/LTE, and there is IDC interference between GNSS and NR/LTE. When there is IDC interference between Wi-Fi and NR/LTE in Figure 1, as shown in Figure 2, after the Wi-Fi transmission signal passes through the transmission filter, there will be high-power spurious harmonic signals entering the adjacent In the NR/LTE receiving signal at the frequency point, this will cause the demodulation of the NR/LTE receiving signal to fail, resulting in NR/LTE not working properly.

Figure 3 shows the frequency bands in which each communication subsystem works in related technologies; DivisionDuplex (TDD) frequency band 40, frequency-division duplex (Frequency-division duplex, FDD) frequency band 7, TDD frequency band 38, and TDD frequency band 41 are adjacent. When different communication technologies in adjacent frequency bands work at the same time, IDC interference will inevitably occur. For Figures 1-3, at least in-device coexistence interference may exist in the user equipment in the following scenarios:

(1) The transmission signal of NR/LTE on TDD frequency band 40 causes IDC interference to the reception signal of Wi-Fi or BT in the ISM frequency band;

(2) The transmission signal of NR/LTE on TDD frequency band 41 causes IDC interference to the reception signal of Wi-Fi or BT in the ISM frequency band;

(3) The transmission signal of NR/LTE on TDD frequency band 38 causes IDC interference to the reception signal of Wi-Fi or BT in the ISM frequency band;

(4) The transmission signal of NR/LTE on FDD frequency band 7 causes IDC interference to the reception signal of Wi-Fi or BT in the ISM frequency band;

(5) The transmission signal of Wi-Fi or BT in the ISM frequency band causes IDC interference to the reception signal of NR/LTE on the TDD frequency band 40;

(6) The transmission signal of Wi-Fi or BT in the ISM frequency band causes IDC interference to the reception signal of NR/LTE on the TDD frequency band 41

(7) The transmission signal of Wi-Fi or BT in the ISM frequency band causes IDC interference to the reception signal of NR/LTE on the TDD frequency band 38;

In addition, there is also IDC interference between the working frequency bands of 5GHz Wi-Fi (5.15GHz～5.35GHz, 5.725GHz～5.825GHz) and the frequency band n79 (4.5GHz～5GHz) of NR, and the working frequency band of GNSS ( 1.571GHz-1.58GHz, 1.598GHz-1.606GHz) and LTE frequency bands 34 and 39 have IDC interference, etc., which are not listed here in this application.

For the IDC interference problem in the user equipment, two methods are adopted in related technologies to solve it:

1. Adopt high-performance filters; the transmitting end of the communication subsystem adopts high-performance transmitting filters to reduce the power of stray harmonics outside the transmitting bandwidth, and the receiving end adopts high-performance receiving filters to further reduce interference signals within the receiving bandwidth power;

2. Different wireless communication technologies adopt a fixed time-sharing working mechanism; for example, as shown in Figure 4, when there is IDC interference, from T1 to T2, Wi-Fi receives and sends normally, while NR stops working or stops sending, so as to Avoid IDC interference to Wi-Fi; from T2 to T3, NR receives and sends normally, while Wi-Fi stops working or stops sending to avoid IDC interference to NR; and so on, Wi-Fi and NR work in different Time, so as to avoid mutual IDC interference.

For the above method 1, although a high-performance filter can reduce IDC interference, it has a limited effect on eliminating IDC interference, especially when the operating frequencies of different communication systems are close, the filter cannot provide enough for IDC interference. suppression. For example, as shown in Figure 5, the Wi-Fi transmitter uses a high-performance transmit filter to reduce the spurious harmonic power of the Wi-Fi transmit signal, but some spurious harmonics still fall into the NR receive signal. It will still cause some interference to NR reception. That is to say, Method 1 is not effective in eliminating IDC interference.

For the above method 2, although the communication subsystems can work normally without IDC interference during their respective working hours, in practical applications, the UE needs to maintain real-time connection and communication with the central office according to the communication technology protocol, and cannot completely autonomously Receive or send according to a fixed moment. For example, for LTE/NR communication technology, the scheduling of UE is controlled by the base station. If the reception or transmission of LTE/NR is stopped for a period of time, the scheduling information will be lost during this period, and the performance of LTE/NR will be reduced. It may cause problems such as UE network loss. For example, as shown in Figure 6: from T2 to T3, the UE is in the NR receiving/sending period, and Wi-Fi cannot work normally; conversely, from Tn to Tn+1, the UE is in the Wi-Fi receiving/sending period, and NR unable to work properly. That is to say, method 2 cannot balance the elimination of IDC interference of the communication subsystem and the communication efficiency of the communication subsystem, and cannot reasonably eliminate the IDC interference, so the achieved effect is not good.

It can be known from the above that the technical solutions for solving the IDC interference between communication subsystems in the related art cannot reasonably and effectively eliminate the IDC interference between different communication subsystems.

Embodiments of the present application provide an interference elimination method and device, electronic equipment, and a computer-readable storage medium, which can reasonably and effectively eliminate interference between different communication subsystems, thereby improving communication between the communication subsystem and external equipment. communication quality.

Frequency point, communication power and data state, and according to the operating frequency point, communication power and data state of each communication subsystem, to determine whether there is IDC interference between the at least two communication subsystems; and at least two communication subsystems When there is IDC interference between the subsystems, by sending a non-real-time message to at least one of the at least two communication subsystems to control the at least one communication subsystem to adjust its own operating frequency or communication power, In this way, IDC interference elimination is realized; and after controlling the at least one communication subsystem to adjust its own operating frequency or communication power, the electronic device determines the frequency of each communication sub-system in the at least two communication sub-systems respectively through the at least two communication sub-systems. The communication quality information of the system itself, such as communication quality parameters or communication status, and according to the communication quality information of the at least two communication subsystems, it is known whether there is still an IDC interference between the at least two communication subsystems after IDC interference is eliminated. IDC interference, wherein, the communication quality parameter may include at least one of the bit error rate and the signal-to-noise ratio; the communication status indicates whether the corresponding communication subsystem is in a normal communication state, for example, the communication status of the NR subsystem indicates that the NR subsystem Whether the system is in the state of normal communication.

It should be noted that, in the embodiments of the present application, the communication subsystem that the electronic device controls to adjust its own working parameters is the communication subsystem that is in the transmitting state among the at least two communication subsystems, and the communication subsystem of the at least two communication subsystems The other communication subsystems are the communication subsystems in the receiving state. In this way, by controlling the communication subsystem that transmits data to adjust its own working parameters, the signal transmitted by the communication subsystem that transmits data can be reduced, and the interference to other communication subsystems that are in the receiving state can be reduced, thereby reducing this IDC interference between at least two communication subsystems.

S104. Based on the communication quality information, when it is determined that there is still interference between the at least two communication subsystems, use real-time messages to control at least one communication subsystem to adjust its communication parameters.

Based on FIG. 8, it can be known that S102 in FIG. 7 can be implemented through S201-S202, It will be described in conjunction with the steps shown in FIG. 8 .

S201. In the case where it is determined that the second communication subsystem interferes with the first communication subsystem according to the first working parameter and the second working parameter, carry the second working parameter in the first non-real-time message and send it to the second communication subsystem A communication subsystem; at least two communication subsystems at least include: a first communication subsystem and a second communication subsystem; the first communication subsystem is used for downlink reception, and the second communication subsystem is used for uplink transmission; the working information includes : the second working parameter of the second communication subsystem; the first working parameter of the first communication subsystem; the non-real-time message includes: the first non-real-time message and the second non-real-time message.

In the following, the first communication subsystem is the NR subsystem, and the second communication subsystem is the Wi-Fi subsystem. The working parameters of the first communication subsystem are called the first working parameters, and the second communication subsystem The operating parameter of the system is called the second operating parameter. It should be noted that the first communication subsystem may also be a Wi-Fi subsystem, and correspondingly, the second communication subsystem may also be an NR subsystem, or the first communication subsystem and the second communication subsystem may also be Other communication subsystems are not limited in this embodiment of the present application.

In some embodiments of the present application, the second working parameter includes a second working frequency and a second communication power. When the electronic device determines that the Wi-Fi subsystem causes IDC interference to the NR subsystem, the electronic device can obtain the working information of the Wi-Fi subsystem including the operating frequency, communication power and data status, etc. , select the working frequency and communication power of the Wi-Fi subsystem, so as to obtain the second working frequency and the second communication power, and carry the second working frequency and the second communication power in the first non-real-time message, And, sending the first non-real-time message to the NR subsystem.

It should be noted that the electronic device may send the first non-real-time message to the NR subsystem through its own control layer. In some embodiments of the present application, the control layer of the electronic device is the controller, and the controller is located in the application layer and is provided with a non-real-time interface, and the protocol layer or platform layer of at least two communication subsystems are also provided with There is a non-real-time interface, and the electronic device realizes information interaction with the at least two communication subsystems through the non-real-time interface of the control layer and the non-real-time interface in the protocol layer or platform layer of the at least two communication subsystems.

In other embodiments of the present application, the first non-real-time message includes: a first sub-message and a second sub-message; when the electronic device determines that the Wi-Fi subsystem interferes with the NR subsystem through the controller, The controller can send a control message to the non-real-time interface of the Wi-Fi subsystem, control the Wi-Fi subsystem to inform the second operating frequency and the second communication power, and the Wi-Fi subsystem sends its own second frequency according to the control message The working frequency and the second communication power are carried in the first sub-message and sent to the controller, and the controller parses the second working frequency and the second communication power of the Wi-Fi subsystem from the first sub-message, and sends The parsed second operating frequency and second communication power are carried in the second sub-message, and the second sub-message is sent to the non-real-time interface of the NR subsystem to realize the second operating frequency and the second communication power of the Wi-Fi subsystem. Sending of the second communication power to the NR subsystem.

S202. Through the first communication subsystem, determine the safe communication power of the second communication subsystem based on the second working parameter and the downlink receiving parameter of the first communication subsystem, and carry the safe communication power in the second non-real-time message , sent to the second communication subsystem to control the second communication subsystem, and adjust the second operating parameter based on the safety communication power; wherein, the safety communication power is used by the second communication subsystem for normal uplink transmission and for using Communication power for normal downlink reception by the first communication subsystem.

After the Wi-Fi subsystem of the electronic device obtains the first operating frequency of the NR subsystem through its own non-real-time interface, it can adjust its second operating frequency based on the first operating frequency to achieve non-real-time The process of real-time IDC interference elimination.

In the embodiment of the present application, the electronic device can first determine whether the difference between its second operating frequency point and the first operating frequency point of the NR subsystem is greater than or equal to a preset threshold through the Wi-Fi subsystem, To determine whether the second operating frequency is close to the first operating frequency of the NR subsystem, and when it is determined that the second operating frequency is close to the first operating frequency of the NR subsystem, the Wi-Fi subsystem itself The second working frequency point is adjusted to the first working frequency point away from the NR subsystem, so as to realize the process of non-real-time IDC interference elimination.

In the case of the first working frequency, you can select one of the multiple available working frequencies of the Wi-Fi subsystem recorded in the working parameter configuration table whose difference with the first working frequency is greater than the preset threshold. The working frequency point, and the second working frequency point of the Wi-Fi subsystem is adjusted to the working frequency point, so as to realize the process of non-real-time IDC interference elimination.

It should be noted that the preset threshold is used to determine whether the target operating frequency is close to the first operating frequency, and the value of the preset threshold can be set according to actual needs, which is not limited in this embodiment of the present application.

In some embodiments of the present application, the above S302 can also be implemented through S3021-S3023:

Through the second communication subsystem, determine whether there is a target operating frequency in the second communication subsystem according to the first operating frequency; Wherein, when the second communication subsystem acts on the target operating frequency, the first communication subsystem Do not interfere.

In some embodiments of the present application, the electronic device can determine whether the Wi-Fi subsystem can work without causing interference to the NR subsystem based on the first operating frequency of the NR subsystem through the Wi-Fi subsystem target working frequency.

In some embodiments, the above-mentioned working parameter configuration table may be pre-stored in the Wi-Fi subsystem, and the electronic device may calculate each parameter of the Wi-Fi subsystem recorded in the working parameter configuration table through the Wi-Fi subsystem. available operating frequency points, and the difference between the first operating frequency point of the NR subsystem, and determine whether each obtained difference is greater than a preset threshold. When each difference obtained is less than the preset threshold, it is determined that the Wi-Fi subsystem does not have a target operating frequency point that does not interfere with the NR subsystem, that is, the Wi-Fi subsystem cannot work on the NR subsystem. The target operating frequency point where the subsystem does not cause interference; if there is a difference greater than the preset threshold, it is determined that the Wi-Fi subsystem has a target operating frequency point that does not interfere with the NR subsystem, that is, the Wi-Fi sub-system The system can work at the target operating frequency that does not interfere with the NR subsystem. For example, the above-mentioned working parameter configuration table may be pre-stored in the Wi-Fi subsystem, and three available working frequency points A1, A2, and A3 of the Wi-Fi subsystem are recorded in the working parameter configuration table. Through the Wi-Fi subsystem, the difference between the working frequency points A1, A2, A3 and the first working frequency point B of the NR subsystem can be calculated respectively, so as to obtain the corresponding differences C1 and A2 between A1 and B The difference C2 between A3 and B, and the difference C3 between A3 and B, and determine whether each difference is greater than a preset threshold.

S3022. When the target operating frequency is determined, adjust the second operating frequency to the target operating frequency, thereby implementing a non-real-time interference elimination process.

When the electronic device determines through the Wi-Fi subsystem that the Wi-Fi subsystem can work at a target operating frequency that does not interfere with the NR subsystem, it can set the second operating frequency of the Wi-Fi subsystem to Adjust to the working frequency to realize the process of non-real-time interference elimination.

S3023. When the target operating frequency point is not determined, use the safe communication power to implement the non-real-time interference elimination process; the safe communication power is used by the second communication subsystem for normal uplink transmission and for making the first communication subsystem Communication power for normal downlink reception by the system.

When the electronic device determines through the Wi-Fi subsystem that the Wi-Fi subsystem cannot work at the target operating frequency point that does not interfere with the NR subsystem, it can directly adjust the communication power of the Wi-Fi subsystem to Secure communication power, or adjust the communication power of the Wi-Fi subsystem below the safe communication power, so as to realize the non-real-time interference elimination process.

In some embodiments of the present application, in the above S201 or S301, according to the first working parameter and the second working parameter, it is determined that the second communication subsystem interferes with the first communication subsystem, which can be implemented through S11:

S11. After determining that the difference between the first operating frequency point and the second operating frequency point is less than the preset difference value, and while the first communication subsystem is performing downlink reception, the second communication subsystem is performing uplink transmission In the case of , it is determined that the second communication subsystem interferes with the first communication subsystem; the first operating parameter includes: the first operating frequency point; the second operating parameter includes: the second operating frequency point.

In an embodiment of the present application, the electronic device may, according to the first operating frequency in the first operating information of the first communication subsystem, and the second operating frequency in the second operating information of the second communication subsystem, Determine the difference between the first working frequency point and the second working frequency point; according to the data status of the first communication subsystem and the data status of the second communication subsystem in the work information, the first and second communication subsystems can be determined Whether the subsystems are working at the same time, and determine which communication subsystem is used for uplink transmission or downlink reception.

Here, the preset difference may be set according to actual conditions, for example, it may be set according to a simulation result, or it may be set with reference to a theoretical value, etc., which is not limited in this embodiment of the present application.

In some embodiments of the present application, S11 can be implemented in the following manner: after it is determined that the difference between the first operating frequency point and the second operating frequency point is less than the preset difference value, and the second communication subsystem is in the first Data state, when the first communication subsystem is in the second data state, it is determined that the second communication subsystem interferes with the first communication subsystem; the first data state indicates that the second communication subsystem is performing uplink transmission, and the second data The status indicates that the first communication subsystem is performing downlink reception.

In the embodiment of the present application, for the LTE subsystem or the NR subsystem, the first data state is the idle state, and the second data state is the connected state; for other subsystems such as the Wi-Fi subsystem or the BT subsystem In other words, the first data status indicates that uplink transmission is being performed, and the second data status indicates that downlink reception is being performed.

For example, for the NR subsystem (or LET subsystem), when the NR subsystem is in the idle state, the NR subsystem is in the working state, and there is no uplink transmission, only downlink reception; and when the NR subsystem is in the connected state, the NR The subsystem is in working state, both uplink sending and downlink receiving.

In the embodiment of the present application, when the first and second communication subsystems are the LTE subsystem and the NR subsystem, and the first data state of the LTE subsystem is an idle state, the second data state of the NR subsystem is a connected state When , there is IDC interference between the LTE subsystem and the NR subsystem. When the first and second communication subsystems are the Wi-Fi subsystem and the BT subsystem, and the second data state of the Wi-Fi subsystem indicates that the Wi-Fi subsystem is performing downlink reception, the first data state of the BT subsystem Indicates that when the BT subsystem performs uplink transmission, there is IDC interference between the Wi-Fi subsystem and the BT subsystem. For other communication subsystems, the principle is the same, and will not be repeated here.

Here, for the case where there is IDC interference between the first and second communication subsystems, for example, when the first and second communication subsystems are Wi-Fi subsystems and LTE subsystems, for example, in Wi-Fi -The working frequency bands of the Fi subsystem and the LTE subsystem are adjacent, and the Wi-Fi subsystem is used for data services such as browsing the Internet and watching movies. At the same time, when the LTE subsystem is used to monitor possible incoming calls, the Wi-Fi subsystem The system will interfere with the incoming call information received by the LTE subsystem, causing the LTE subsystem to fail to receive incoming call information. And, exemplary, in the case where the first and second communication subsystems are the BT subsystem and the NR subsystem, for example, the operating frequency bands of the BT subsystem and the NR system are adjacent, and the BT subsystem is used to connect Bluetooth Headphones or Bluetooth speakers. At the same time, when the NR subsystem is used to order music online, the BT subsystem and the NR subsystem interfere with each other, resulting in intermittent music playback.

In some embodiments of the present application, determining that interference still exists between at least two communication subsystems based on communication quality information in S104 of FIG. 7 can be implemented through S401:

S401. Based on the communication quality parameters of each of the at least two communication subsystems, determine that the communication quality parameters of at least any one of the at least two communication subsystems do not meet the preset conditions Next, it is determined that interference still exists between at least two communication subsystems; the communication quality information includes: communication quality parameters.

The communication quality parameter may be at least one of a bit error rate and a signal-to-noise ratio, and the electronic device may obtain at least one of the bit error rate and the signal-to-noise ratio of the Wi-Fi subsystem and the NR subsystem respectively through the controller, so as to pass In the Wi-Fi subsystem and the NR subsystem, at least one of the bit error rate and signal-to-noise ratio of each communication subsystem, and the size relationship between the corresponding communication threshold, to determine the Wi-Fi subsystem and NR respectively Whether the subsystem is in a normal communication state, so that when the Wi-Fi subsystem or the NR subsystem is not in a normal communication state, or neither the Wi-Fi subsystem nor the NR subsystem is in a normal communication state, determine There is still IDC interference between the Wi-Fi subsystem and the NR subsystem, so real-time messages can be used to continue to control the Wi-Fi subsystem to adjust its own communication parameters.

Exemplarily, in the case that the communication quality parameter includes a bit error rate, the electronic device may compare the bit error rate of each communication subsystem with a preset bit error rate threshold, and determine whether there is a bit error rate of a communication subsystem When the BER is greater than or equal to the BER threshold, it is determined that IDC interference still exists between the Wi-Fi subsystem and the NR subsystem. And, for example, in the case that the communication quality parameters include a bit error rate and a signal-to-noise ratio, the electronic device may compare the bit error rate of each communication subsystem with a preset bit error rate threshold, and compare each The signal-to-noise ratio of each communication subsystem is compared with the preset signal-to-noise ratio threshold, and when the bit error rate of a communication subsystem is greater than or equal to the bit error rate threshold, and the signal-to-noise ratio is less than or equal to the signal-to-noise ratio threshold In this case, it is determined that IDC interference still exists between the Wi-Fi subsystem and the NR subsystem; in this way, the accuracy of judging whether there is still IDC interference between the Wi-Fi subsystem and the NR subsystem can be improved.

In other embodiments of the present application, determining that there is still interference between at least two communication subsystems based on the communication quality information in S104 of FIG. 7 can also be implemented through S501:

S501. Based on the communication state of each communication subsystem in at least two communication subsystems, if at least any one of the at least two communication subsystems is determined not to be in a normal communication state, determine at least two There is still interference between the communication subsystems; the communication quality information includes: communication status; the communication status indicates whether the corresponding communication subsystem is in a normal communication state.

The electronic device can obtain the communication status of the Wi-Fi subsystem and the NR subsystem respectively through the controller, and directly know whether the communication subsystem is in a normal communication state through the communication status of each communication subsystem, thereby directly determining the Wi-Fi subsystem. -Whether there is a communication subsystem that is not communicating normally in the Fi subsystem and the NR subsystem, and if a communication subsystem that is not communicating normally is determined from the Wi-Fi subsystem and the NR subsystem, determine the Wi-Fi subsystem - There is still IDC interference between the Fi subsystem and the NR subsystem, so that real-time messages can be used to continue to control the Wi-Fi subsystem to adjust its own communication parameters. In this way, it is more convenient than judging whether the communication subsystem is in a normal communication state through the communication quality parameters, so that the efficiency of subsequent IDC interference elimination can be improved.

In some embodiments, referring to FIG. 10 , FIG. 10 is a schematic flow chart of an optional interference elimination method provided by an embodiment of the present application. Based on FIG. 7 , the use of real-time messages in S104 to control at least one communication subsystem to adjust its communication Parameters can be implemented through S601-S602, which will be described in conjunction with the steps shown in FIG. 10 .

S601. Determine the high-priority downlink time slot information of the first communication subsystem in real time through the first communication subsystem, and carry the downlink time slot information in a real-time message and send it to the second communication subsystem; at least two communication subsystems At least including: a first communication subsystem and a second communication subsystem.

Here, the high-priority downlink time slot information may at least include: paging information, downlink reception during the access process, cell system information, high-priority measurement information, and the like.

When the electronic device determines that there is still in-device coexistence interference between the Wi-Fi subsystem and the NR subsystem, it can control the NR subsystem to determine the paging information of the NR subsystem itself, the downlink reception during the access process, High-priority downlink time slot information such as cell system information and high-priority measurement information, so as to determine the high-priority downlink time slot information of the NR subsystem itself through the NR subsystem, and through the NR subsystem, determine The high-priority downlink time slot information is carried in the real-time message and sent to the Wi-Fi subsystem.

In the embodiment of the present application, each communication subsystem of the electronic device is also equipped with a real-time interface. When the electronic device sends a control message to the NR subsystem through the non-real-time interface of the controller, the NR subsystem The control message received by its own non-real-time interface determines its own high-priority downlink time slot information, and directly sends the high-priority downlink time slot information to the Wi-Fi subsystem through its own real-time interface. The real-time interface is used to send the high-priority downlink time slot information determined by the NR subsystem to the Wi-Fi subsystem by using real-time messages.

S602. Stop uplink transmission in the time slot corresponding to the downlink time slot information through the second communication subsystem.

The electronic device can control the Wi-Fi subsystem to stop in the time period corresponding to the high-priority downlink time slot of the NR subsystem when it receives the high-priority downlink time slot information of the NR subsystem through the controller. Send data to the first external device, so that the Wi-Fi subsystem will not cause interference to the NR subsystem within a time period corresponding to the high-priority downlink time slot information of the NR subsystem.

In some embodiments of the present application, after S602 in FIG. 10 , the following steps may also be performed:

S603. Through the second communication subsystem, perform uplink transmission again in a retransmission manner.

Continuing to illustrate with the above example, the electronic device can control the Wi-Fi subsystem to resume sending data to the first external device through the retransmission mechanism after the high-priority downlink time slot information of the NR subsystem ends.

In the embodiment of the present application, since the Wi-Fi subsystem can stop working in the time period corresponding to the high-priority downlink time slot information of the NR subsystem, and can work normally in other time periods, so compared to the above In the method 2 in the related art, different wireless communication technologies adopt a fixed time-sharing working mechanism, which reduces the limitation on the working time of the corresponding communication subsystem, thereby greatly improving the communication efficiency of the corresponding communication subsystem.

In some embodiments, the interference elimination method provided in the embodiment of the present application may be implemented as the subsystem IDC interference elimination function in the above-mentioned overall interference processing control module. Taking the Wi-Fi subsystem and the NR subsystem as examples, the above interference processing general control module is also used to identify IDC interference based on the information reported by the Wi-Fi subsystem and the NR subsystem. When the Wi-Fi subsystem and the NR subsystem When the system working frequency bands are adjacent, the IDC interference elimination function of the subsystem is started; otherwise, the IDC interference elimination function of the subsystem is turned off, as shown in Figure 12:

S20. Receive a non-real-time message.

In S20, the interference processing general control module receives the non-real-time message from the subsystem. In some embodiments, the non-real-time message includes: working status information of Wi-Fi and NR. Exemplarily, it includes: Wi-Fi and NR working frequency bands, system working status (idle state, connected state, etc.), whether NR is ready to trigger high-priority events such as access, etc.

S23. Turn off the interference cancellation function of the subsystem.

S28. Start the real-time interference elimination function.

In S28, the interference processing general control module activates the real-time IDC interference elimination function among the IDC interference elimination functions of the subsystems, and further processes the IDC interference between subsystems.

It should be noted that the method flow in Figure 12 is also applicable to interference cancellation between the BT subsystem and the NR subsystem, interference cancellation between the Wi-Fi subsystem and the LTE subsystem, interference cancellation between the BT subsystem and the LTE subsystem, etc. .

In some embodiments, the interference elimination process of the non-real-time interference processing module in the subsystem of FIG. 11 may be as shown in FIG. 13 . Fig. 13 shows a non-real-time interference elimination process in which Wi-Fi uplink transmission interferes with NR downlink reception, and a non-real-time interference elimination process in which NR uplink transmission interferes with Wi-Fi downlink reception.

For the non-real-time interference elimination process in which Wi-Fi uplink transmission interferes with NR downlink reception in Figure 13, the NR subsystem transmits its operating frequency and working status to the Wi-Fi subsystem through the IDC general control module in the form of non-real-time messages . When NR is in the idle state, there is no uplink transmission, and it will not interfere with Wi-Fi downlink reception. When Wi-Fi works in a frequency band close to NR, Wi-Fi uplink transmission will interfere with NR downlink reception. In order to eliminate Wi-Fi uplink interference, NR calculates the safe uplink transmission power of Wi-Fi at adjacent frequency points according to its downlink receiving performance. When the uplink transmission power of Wi-Fi is lower than the safe transmission power, the interference of Wi-Fi uplink transmission on NR downlink reception can be ignored, and NR can normally receive downlink. The NR subsystem transmits the calculated Wi-Fi uplink secure transmission power information to the Wi-Fi subsystem through the IDC general control module in the form of non-real-time messages. The Wi-Fi subsystem receives information such as the NR's working frequency, working status, and uplink safe transmission power. When the Wi-Fi subsystem is working, it can transmit uplink on a frequency band far away from NR to avoid interference with NR downlink reception. For the case where the Wi-Fi subsystem must work in a frequency band close to NR, the Wi-Fi subsystem can adopt an interference elimination method to ensure that its uplink transmission power is lower than the safe transmission power, and eliminate the interference of Wi-Fi uplink transmission on NR downlink reception .

For the non-real-time interference elimination process in which NR uplink transmission interferes with WiFi downlink reception in Figure 13, the NR subsystem transmits its operating frequency and working status to the Wi-Fi subsystem through the IDC general control module in the form of non-real-time messages. When NR is in the connected state, NR uplink transmission will interfere with Wi-Fi downlink reception. In order to reduce NR uplink interference, Wi-Fi calculates NR uplink safe transmit power according to its downlink receiving performance. When the uplink transmission power of NR is lower than the safe transmission power, the interference of NR uplink transmission on Wi-Fi downlink reception can be ignored, and Wi-Fi can normally receive downlink. When the Wi-Fi subsystem works, it can receive downlink on a frequency band far away from NR. When the WiFi subsystem must work in a frequency band close to NR, Wi-Fi informs NR to limit its uplink transmission power. The Wi-Fi subsystem transmits the calculated NR uplink secure transmission power information to the NR subsystem through the IDC general control module in the form of non-real-time messages. The NR subsystem adopts an interference elimination method to ensure that its uplink transmission power is lower than the safe transmission power, and eliminates the interference of NR uplink transmission on Wi-Fi downlink reception.

It should be noted that the above non-real-time interference cancellation method is also applicable to the interference cancellation between the BT subsystem and the NR subsystem, the interference cancellation between the Wi-Fi subsystem and the LTE subsystem, the interference cancellation between the BT subsystem and the LTE subsystem, etc. .

In some embodiments, taking the Wi-Fi subsystem and the NR subsystem as examples, FIG. 14 shows the real-time interference elimination process of Wi-Fi uplink transmission interfering with NR downlink reception, and the process of NR uplink transmission interfering with Wi-Fi downlink reception. Real-time interference cancellation process. For the real-time interference elimination process in which Wi-Fi uplink transmission interferes with NR downlink reception in Figure 14, the NR subsystem identifies its high-priority downlink time slot in advance in real time. Wherein, the high-priority downlink refers to important downlink reception information in NR, including but not limited to paging information, downlink reception during access process, system information, important measurement information and so on. The NR subsystem transmits the identified high-priority downlink time slot information (such as location, duration, etc.) to the Wi-Fi subsystem through a real-time interface. The Wi-Fi subsystem stops Wi-Fi transmission at the NR high-priority downlink time slot to eliminate interference to NR high-priority downlink reception. It can be understood that because the duration of the high-priority downlink time slot is very short, the short-stop transmission can be resumed through retransmission, and Wi-Fi can still work normally. There is no Wi-Fi transmission interference at the NR high-priority downlink time slot, which ensures the reception performance of the NR high-priority downlink time slot.

For the real-time interference elimination process in which NR uplink transmission interferes with Wi-Fi downlink reception in Figure 14, the Wi-Fi subsystem identifies its high-priority downlink time slot in advance in real time. The Wi-Fi subsystem transmits the identified high-priority downlink time slot information (such as location, duration, etc.) to the NR subsystem through a real-time interface. The NR subsystem stops NR transmission at the Wi-Fi high-priority downlink time slot to eliminate interference to Wi-Fi high-priority downlink reception.

It can be understood that since the duration of the high-priority downlink time slot is very short, the short-stop transmission can be resumed through retransmission, and the NR can still work normally. There is no NR transmission interference in the Wi-Fi high-priority downlink time slot, which ensures the reception performance of the Wi-Fi high-priority downlink time slot.

It should be noted that the above real-time interference cancellation method is also applicable to interference cancellation between the BT subsystem and the NR subsystem, interference cancellation between the Wi-Fi subsystem and the LTE subsystem, interference cancellation between the BT subsystem and the LTE subsystem, and the like.
