Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a coexistence interference avoidance method, apparatus, communication equipment and storage medium. Background Art

[0002] In communication equipment, multiple communication systems such as Wi-Fi, Ultra WideBand (UWB) wireless communication technology based on Time Division Duplex (TDD) Long-Term Evolution (LTE) technology (abbreviated as TD-LTE) are used together. Different wireless communication technologies may have very close signal frequency bands, for example, the signal frequency band of Wi-Fi 2.4G is very close to that of TD-LTE.

[0003] Since there is a nonlinear relationship between the output signal and the input signal of the device in the communication equipment, this nonlinear phenomenon will cause signal distortion and affect the performance of the communication equipment. When LTE signals and Wi-Fi 2.4G signals are used together, the nonlinearity of the devices in the communication equipment may generate higher out-of-band spurious signals, thereby generating coexistence interference and affecting the normal transmission of LTE signals and Wi-Fi 2.4G signals. Summary of the invention

[0006] In a coexistence interference avoidance method provided in an embodiment of the present application, when a target signal and an interference signal work together, a communication device can detect whether the target signal is interfered with by detecting a first received signal strength indication corresponding to the target signal. When it is determined that the first received signal strength does not meet the preset requirements, it can be determined that the target signal is interfered with. The communication device can adjust the time slot parameters of the target signal so that the target signal is away from the frequency band of the interference signal and reduce the interference degree of the interference signal. When it is detected that the first received signal strength indication meets the preset requirements, it can be determined that the interference degree is reduced.

[0023] It should be noted that the terms "first" and "second" in the specification, claims and drawings of the present application are used to distinguish similar objects rather than to describe a specific order or sequence.

[0024] It should also be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchangeable with each other, and some of the steps can also be deleted.

[0025] Some embodiments will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0026] Considering that when multiple communication systems are used together, the nonlinearity of the devices in the communication equipment may generate higher out-of-band spurious signals, thereby generating coexistence interference, the relevant coexistence interference avoidance scheme adopts the method of improving the performance of the devices in the communication equipment or increasing the out-of-band isolation in design (for example, increasing the out-of-band isolation by filtering, removing noise, etc.) to reduce the out-of-band spurious signals; or reducing the transmission power of the interference signal to reduce the out-of-band spurious signals, thereby reducing the impact of the out-of-band spurious signals on the target signal; or completely disabling the situation where the target signal and the interference signal work together. However, due to the limited performance improvement of the devices in the current communication equipment, the occurrence of coexistence interference cannot be effectively avoided; reducing the transmission power of the interference signal may affect the data transmission of the interference signal, thereby affecting the user experience; completely disabling the situation where the target signal and the interference signal work together will limit the user's bandwidth usage.

[0027] In order to solve the above problems, this solution provides a coexistence interference avoidance method. When coexistence interference is detected among multiple signals, the communication device can adjust the waveform of the TDD signal by adjusting the time slot parameters of the signal in the time division duplex (TDD) mode among the multiple signals, so that the TDD signal is far away from the frequency band of other interference signals, thereby reducing the impact of the interference signal on the TDD signal and achieving coexistence interference avoidance.

[0028] In some embodiments, the target signal includes a TDD signal, for example, a TD-LTE signal, a Wi-Fi signal, a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) signal, etc. The interference signal refers to a signal adjacent to the frequency band of the target signal, for example, a Wi-Fi signal, an Ultra-Wideband (UWB) wireless communication signal, etc. When the communication device enables the target signal alone for communication, the target signal is not interfered with and the received signal strength is normal. When the communication device uses the target signal and the interference signal for communication at the same time, if the interference signal is transmitted at a higher power, due to the nonlinearity of the device in the communication device, a higher out-of-band spurious signal may be generated. Since the target signal is adjacent to the interference signal frequency band, the out-of-band spurious signal will interfere with the target signal in the adjacent frequency band, and may especially cause the channel of the target signal to generate blocking interference, thereby affecting the received signal strength of the target signal. Therefore, by detecting the received signal strength of the target signal, it is determined whether the target signal is interfered.

[0029] See also Figure 1 As shown, it is an application scenario diagram of the coexistence interference avoidance method provided in an embodiment of the present application, such as Figure 1 As shown, the communication device 100 is connected in communication with the base station 200. When the target signal and the interference signal work together, the communication device 100 can detect the first received signal strength indication corresponding to the target signal. When it is determined that the first received signal strength indication does not meet the preset requirements, the communication device 100 adjusts the time slot parameters of the target signal and attempts to re-establish a communication connection with the base station 200. After the communication device 100 re-establishes the communication connection with the base station 200, the communication device 100 re-detects the first received signal strength indication corresponding to the target signal until it is detected that the first received signal strength indication meets the preset requirements. The communication device determines the adjusted time slot parameters as the target time slot parameters, and controls the target signal to communicate according to the target time slot parameters.

[0030] In some embodiments of the present application, the communication connection includes but is not limited to any one or more of a wired communication connection, a wireless communication connection, and a cellular network. The communication device 100 includes but is not limited to any one of a smart phone, a tablet, a laptop, etc. The base station 200 includes but is not limited to an antenna.

[0031] See also Figure 2 As shown in FIG. 1 , it is a flowchart of the implementation of the coexistence interference avoidance method provided in an embodiment of the present application, and the method is applied to a communication device. The following embodiments use the method to Figure 1 The communication device 100 in the embodiment is used as an example to illustrate the method, which includes the following steps.

[0032] S11: When the target signal and the interference signal work together, a first received signal strength indicator corresponding to the target signal is detected.

[0033] In some embodiments, the target signal includes a TDD signal, such as a TD-LTE signal, a Wi-Fi signal, a TD-SCDMA signal, etc. The interference signal refers to a signal with a frequency band close to the target signal. Interference signals include Wi-Fi signals, ultra-wideband (UWB) wireless communication signals, etc. The first received signal strength indication is used to characterize the strength of the received signal of the channel corresponding to the target signal. The larger the value of the first received signal strength indication, the higher the received signal strength of the channel corresponding to the target signal.

[0034] In some embodiments, the communication device may detect the type of signal currently in use, and when it is determined that the target signal and the interference signal work together, the communication device may detect the first received signal strength indication corresponding to the target signal to determine the degree of interference to the target signal.

[0035] In some embodiments, when the target signal (e.g., TD-LTE signal) is working normally, its corresponding first received signal strength indication should meet preset requirements, such as being within a certain threshold range. If the target signal is interfered with by an interference signal, the strength of the received signal of the channel corresponding to the target signal will be weakened, that is, the value of the first received signal strength indication corresponding to the target signal will decrease. When the value of the first received signal strength indication decreases to not meet the preset requirements, it indicates that the target signal is being interfered with. Therefore, the communication device can determine whether the target signal is subject to coexistence interference when the target signal is used together with the interference signal by detecting the first received signal strength indication corresponding to the target signal.

[0036] In some embodiments of the present application, when the target signal works independently, the second received signal strength indication corresponding to the target signal is read; when the target signal and the preset signal work together, the third received signal strength indication corresponding to the target signal is read; when the first deviation value of the third received signal strength indication relative to the second received signal strength indication is greater than a preset threshold, the preset signal is determined to be an interference signal.

[0037] In some embodiments, since the frequency bands of the interference signal and the target signal are close, the first received signal strength indication corresponding to the target signal may be affected when the target signal and the interference signal are used together. In some embodiments, it is possible to determine whether the signal used in the communication device is an interference signal close to the target signal frequency band by comparing the following two situations: when the target signal works independently, the second received signal strength indication corresponding to the target signal; when the target signal and the preset signal work together, the third received signal strength indication corresponding to the target signal. Specifically, the communication device can calculate the first deviation value of the third received signal strength indication relative to the second received signal strength indication, and when it is determined that the first deviation value is greater than the preset threshold, it can be determined that the preset signal is an interference signal. Among them, the preset threshold can be set by default, for example, the preset threshold can be 20dBm, etc.

[0038] S12: When the first received signal strength indication does not meet the preset requirement, adjust the time slot parameter of the target signal until the detected first received signal strength indication meets the preset requirement, and determine the adjusted time slot parameter as the target time slot parameter.

[0039] In some embodiments, the preset requirements include but are not limited to the requirements of the 3rd Generation Partnership Project (3GPP). The time slot parameters include but are not limited to the subframe and time slot of the target signal.

[0040] In some embodiments, adjusting the time slot, subframe and other parameters of the target signal can make the target signal away from the frequency band of the interference signal, thereby reducing the interference degree of the interference signal on the target signal, reducing the coexistence interference, and enhancing the received signal strength of the channel corresponding to the target signal, so as to achieve normal communication of the target signal. Therefore, the communication device can avoid the coexistence interference generated when the target signal and the interference signal are used together by adjusting the time slot parameters of the target signal. In the process of adjusting the time slot parameters, the communication device can detect the first received signal strength indication in real time. When it is determined that the first received signal strength indication meets the preset requirements, it can be determined that the coexistence interference currently suffered by the target signal is weak and normal communication can be maintained. At this time, the communication device can obtain the current adjusted time slot parameters and determine the adjusted time slot parameters as the target time slot parameters. The target signal can maintain normal communication based on the target time slot parameters and is less interfered.

[0041] As an example, see Figure 3 As shown in FIG. 1 , an example diagram of a coexistence interference avoidance method provided in an embodiment of the present application is shown. Figure 3As shown, the frequency range of Band 40 in TD-LTE is 2300MHz~2400MHz, the frequency range of Band 41 in TD-LTE is 2496MHz~2690MHz, the frequency range of Band 41 in TD-LTE is 2570MHz~2620MHz, the frequency range of Band 7 (Up) in LTE-FDD is 2500MHz~2570MHz, the frequency range of Band 7 (Down) in LTE-FDD is 2620MHz~2690MHz, and the frequency range of Wi-Fi 2.4G (channel 1 to channel 13) is 2412MHz~2484MHz. It can be found that the frequency bands of TD-LTE signals and Wi-Fi 2.4G signals are close. In some embodiments, as Figure 4 As shown, the waveform of the TDD-LTE signal can be changed by adjusting the time slot parameters of the TDD-LTE signal (for example, from time slot 1 to time slot 3), so that the TDD-LTE signal is away from the frequency band of the Wi-Fi 2.4G signal, thereby reducing or avoiding the interference of the Wi-Fi 2.4G signal.

[0042] In some embodiments of the present application, adjusting the time slot parameters of the target signal includes: determining a time slot adjustment range based on the first received signal strength indication and the second received signal strength indication; and adjusting the time slot parameters based on the time slot adjustment range.

[0043] In some embodiments, since the first received signal strength indication represents the received signal strength of the channel corresponding to the target signal when the target signal and the interference signal are used together, and the second received signal strength indication represents the received signal strength of the channel corresponding to the target signal when the target signal works independently (normally), the communication device can determine the difference in received signal strength of the channel corresponding to the target signal when the target signal is interfered with and when it works normally by comparing the first received signal strength indication with the second received signal strength indication. The communication device can determine the time slot adjustment range of the target signal based on the received signal strength difference. Under the time slot parameters within the time slot adjustment range, the first received signal strength indication of the target signal can meet the preset requirements.

[0044] In some embodiments of the present application, determining a time slot adjustment range based on a first received signal strength indication and a second received signal strength indication includes: determining a second deviation value of the first received signal strength indication relative to the second received signal strength indication; and determining the time slot adjustment range based on the second deviation value.

[0045] In some embodiments, the second deviation value of the first received signal strength indication relative to the second received signal strength indication is the received signal strength difference value of the channel corresponding to the target signal when the target signal is interfered and when it is working normally. The communication device can obtain the received signal strength corresponding to the target signal under different time slot parameters, and then determine the time slot adjustment range according to the received signal strength corresponding to the target signal under different time slot parameters and the received signal strength difference value.

[0046] In some embodiments of the present application, the time slot parameter includes a subframe parameter, and adjusting the time slot parameter of the target signal includes: adjusting the time slot parameter by adjusting the subframe parameter.

[0047] In some embodiments, the target signal includes multiple subframes (e.g., subframe 1 / 2 / 3 / 5 / 6, etc.). The communication device adjusts the subframe parameters to change the time slot, thereby changing the waveform of the target signal, so that the target signal is away from the frequency band of the interference signal, thereby achieving coexistence interference avoidance.

[0048] In some embodiments of the present application, when the first received signal strength indication does not meet the preset requirements, the operating frequency band of the target signal is adjusted until the detected first received signal strength indication meets the preset requirements, and the adjusted operating frequency band is determined as the target operating frequency band.

[0049] In some embodiments, when it is determined that the first received signal strength indication does not meet the preset requirements, that is, when it is determined that the target signal and the interference signal have coexistence interference, the communication device can also change the current operating frequency band of the target signal by adjusting the center frequency of the target signal, thereby changing the position of the target signal in the spectrum, so that the target signal is away from the frequency band of the interference signal. When it is detected that the first received signal strength indication meets the preset requirements, the communication device determines the adjusted operating frequency band as the target operating frequency band.

[0050] In some embodiments, the communication device adjusts the time slot parameters of the target signal and may also change the center frequency of the target signal, thereby changing the position of the target signal in the spectrum so that the target signal is away from the frequency band of the interference signal.

[0051] In some embodiments of the present application, the communication device is connected to the base station for communication, and the time slot parameters of the target signal are adjusted until the detected first received signal strength indication meets the preset requirements, including: adjusting the time slot parameters of the target signal, and re-establishing the communication connection with the base station; after determining that the communication connection with the base station is re-established, returning to the step of detecting the first received signal strength indication corresponding to the target signal until the detected first received signal strength indication meets the preset requirements.

[0052] In some embodiments, when the time slot parameters of the target signal change, the communication device needs to notify the base station and renegotiate the time slot configuration, so the communication device needs to re-establish the communication connection with the base station to adjust the time slot parameters of the target signal. After determining that the communication connection with the base station is re-established, the communication device can re-detect the first received signal strength indication corresponding to the target signal and determine the first received signal strength indication. If it is determined that the first received signal strength indication meets the preset requirements, the communication device can control the target signal to communicate according to the adjusted time slot parameters. If it is determined that the first received signal strength indication does not meet the preset requirements, the communication device can adjust the time slot parameters of the target signal again until the detected first received signal strength indication meets the preset requirements, thereby ensuring that coexistence interference can be avoided and the normal use of the target signal is guaranteed.

[0053] S13: Control the target signal to communicate according to the target time slot parameters.

[0054] In some embodiments, after determining the target time slot parameters, the communication device may control the target signal to communicate according to the target time slot parameters.

[0055] In some embodiments, the communication device can perform real-time detection of the first received signal strength indication of the target signal. When it is detected that the first received signal strength indication does not meet the preset requirements, the time slot parameters can be adjusted again until the first received signal strength indication meets the preset requirements, thereby ensuring normal communication of the target signal.

[0056] In a coexistence interference avoidance method provided in an embodiment of the present application, when a target signal and an interference signal work together, a communication device can detect whether the target signal is interfered with by detecting a first received signal strength indication corresponding to the target signal. When it is determined that the first received signal strength does not meet the preset requirements, it can be determined that the target signal is interfered with. The communication device can adjust the waveform of the target signal by adjusting the time slot parameters of the target signal so that the frequency band of the target signal is away from the frequency band of the interference signal, thereby reducing the interference degree of the interference signal. When it is detected that the first received signal strength indication meets the preset requirements, it can be determined that the interference degree is reduced. At this time, the communication device can determine the adjusted time slot parameters as the target time slot parameters, and control the target signal to communicate according to the target time slot parameters. This scheme can avoid coexistence interference when multiple communication systems are used together, and ensure the normal use of the multiple communication systems.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
