[0002] The N79 frequency band belongs to the core high-frequency band of the 5G network. It is the highest frequency band available to operators. It has the advantages of large capacity and high speed, but its penetration is poor. The 4800-5000MHz where the N79 frequency band is located is the highest in the 5G frequency band (within Sub-6G). The advantages are fast speed and larger capacity. It can be used in shopping malls, subways, large gatherings and other limited space intensive communication scenarios, such as sending videos during large-scale sports events and playing games in the subway.

[0003] When the device works in the frequency bands corresponding to the N79 standard protocol and the WIFI 5G standard protocol at the same time, since the frequency bands corresponding to the N79 standard protocol and the WIFI 5G standard protocol are close, there is mutual interference during use, resulting in a low WIFI rate and a high bit error rate.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0021] Figure 1 A method for preventing mutual interference provided by an embodiment of the present application is as follows: Figure 1 As shown, the method steps of the embodiment of the present application include:

[0022] Step 101, determining a standard protocol corresponding to a current working frequency band of a device, wherein the device supports a first standard protocol and a second standard protocol, and the working frequency bands corresponding to the first standard protocol and the second standard protocol are different;

[0023] Step 102, when the device simultaneously operates in the working frequency bands corresponding to the first standard protocol and the second standard protocol, perform at least one of the following operations: reduce the transmission power of the device in the working frequency band corresponding to the first standard protocol or the second standard protocol; adjust the device in the working frequency band corresponding to the first standard protocol and / or the second standard protocol.

[0024] It should be noted that, when the device works in the working frequency bands corresponding to the two standard protocols, by reducing the transmission power of one of them, the mutual interference generated by the two standard protocols in the corresponding frequency band can be reduced. For example, if the transmission power of the first standard protocol in the corresponding frequency band is reduced, the interference intensity of the device working in the first standard protocol in the corresponding frequency band to the device working in the second standard protocol in the corresponding frequency band is reduced compared to before the reduction. In addition, since the working frequency bands corresponding to the first standard protocol and the second standard protocol are different, the inventor found that not all frequency bands of the device working in the first standard protocol will interfere with the working frequency band corresponding to the second standard protocol. Taking the first standard protocol as the WIFI5G standard protocol and the second standard protocol as the N79 standard protocol as an example, the inventor found that the device working in the N79 standard protocol, with a bandwidth of 80M and a center frequency of 4905MHz, has basically no interference with all frequency points of the device working in the WIFI 5G standard protocol.

[0025] Through the above steps 101 and 102, in an embodiment of the present application, if the device simultaneously operates in the working frequency bands corresponding to the first standard protocol and the second standard protocol, the mutual interference when the device operates in the frequency bands corresponding to the two standard protocols can be reduced by reducing the transmission power of the device in the working frequency band corresponding to the first standard protocol or the second standard protocol, and / or adjusting the working frequency band of the device in the first standard protocol and / or the second standard protocol.

[0026] In an optional implementation manner of an embodiment of the present application, when the first standard protocol in the embodiment of the present application is the N79 standard protocol and the second standard protocol is the WIFI 5G standard protocol, the method of reducing the transmission power of the device in the working frequency band corresponding to the first standard protocol or the second standard protocol involved in the above step 102 can further be: reducing the transmission power of the device in the working frequency band corresponding to the WIFI 5G standard protocol or the N79 standard protocol.

[0027] Based on this, in a specific example, Figure 2 As shown in the figure, when the device works in the frequency band corresponding to the N79 standard protocol and its transmission power is 24dBm, the non-signaling sensitivity of 5G WLAN (WIFI 5G standard protocol) is tested, and the following results can be obtained:

[0028] 1) For the N79 standard protocol with BW=40M and a center frequency of 4980MHz, when the N79 network is turned on and off, the sensitivity of the device when WLAN BW=40M is turned on is -71 and -70.5 respectively, which means that the sensitivity deteriorates by 0.5dB, that is, the sensitivity deterioration value is 0.5dB. Similarly, for the N79 standard protocol with BW=40M and a center frequency of 4980MHz, when the N79 network is turned on and off, the sensitivity deteriorates by 1dB when WLAN BW=40M is turned on. It can be seen that for N79, BW=40M, and the center frequency of 4980MHz have basically no interference with WLAN BW=40M and BW=160M ​​test frequency points.

[0029] 2) BW = 40M, the N79 standard protocol with a center frequency of 4905MHz has basically no interference with the WLAN test frequency.

[0030] 3) BW = 20M, the N79 standard protocol with a center frequency of 4950MHz has the greatest impact on the WLAN 20M 5180MHz frequency band, with the sensitivity deteriorating by 15dB.

[0031] 4) BW = 40M, the N79 standard protocol with a center frequency of 5190MHz has the greatest impact on the WLAN 40M 5190MHz frequency band, with the sensitivity deteriorating by 9dB.

[0032] 5) BW = 100M, the N79 standard protocol with a center frequency of 4905MHz interferes with the WLAN 40M 5190MHz band, and the sensitivity deteriorates by 4dB. It can be seen that the mutual interference is relatively large.

[0033] 6) BW = 80M, the N79 standard protocol with a center frequency of 4960MHz interferes with the WLAN 40M5190MHz band, and the sensitivity deteriorates by 4.5dB. It can be seen that the mutual interference is relatively large.

[0034] 7) When BW=80M and the center frequency of the N79 standard protocol is 4905MHz, the sensitivity of the WLAN test frequency points deteriorates by 1.5 and 0.5 respectively, indicating that the mutual interference is small.

[0035] 8) BW = 80M, the sensitivity of the N79 standard protocol with a center frequency of 4800MHz to the WLAN test frequency points deteriorates by 0.5 and 0 respectively, and there is little or no interference between them.

[0036] It can be seen that the degree of mutual interference between the N79 standard protocol and the WIFI 5G standard protocol is different in different frequency bands. That is, when the device works in the N79 standard protocol and the WIFI 5G standard protocol at the same time, the working frequency bands corresponding to different N79 standard protocols and the working frequency bands corresponding to different WIFI 5G standard protocols have different effects on the sensitivity of the device.

[0037] Based on this, in an optional implementation manner of the embodiment of the present application, after reducing the transmission power of the device in the working frequency band corresponding to the WIFI 5G standard protocol, the method of the embodiment of the present application further includes:

[0038] Step 11, when the transmission power of the working frequency band corresponding to the WIFI 5G standard protocol is zero, determine whether the device is moved out of the network corresponding to the N79 standard protocol;

[0039] Step 12, when the device moves out of the network corresponding to the N79 standard protocol, determine whether to enable the device to work in the network corresponding to the WIFI 5G standard protocol;

[0040] Step 13, when the state of the network corresponding to the WIFI 5G standard protocol is manually set to a closed state, keep the device in a closed state of the network corresponding to the WIFI 5G standard protocol;

[0041] Step 14, when the state of the network corresponding to the WIFI 5G standard protocol is not a manually set closed state, the control device is controlled to work again in the working frequency band corresponding to the WIFI 5G standard protocol.

[0042] Through the above steps 11 to 15, if the transmission power of the working frequency band corresponding to the WIFI 5G standard protocol is reduced to zero in order to reduce the degree of mutual interference caused by the device working in the working frequency band corresponding to the N79 standard protocol and the working frequency band corresponding to the WIFI 5GHz standard protocol at the same time, after the device moves out of the network corresponding to the N79 standard protocol, the device can be controlled again to work in the working frequency band corresponding to the WIFI 5G standard protocol according to needs, without the need for manual control by the user, so as to improve the user experience of the device.

[0043] In an optional implementation manner of the embodiment of the present application, the manner of adjusting the working frequency band of the device corresponding to the first standard protocol and / or the second standard protocol involved in the above step 102 may further include:

[0044] Step 21, when the device works in the working frequency band corresponding to the N79 standard protocol and the low-frequency channel corresponding to the WIFI 5G standard protocol, adjust the working frequency band of the device in the WIFI 5G standard protocol from the low-frequency channel to the high-frequency channel;

[0045] Among them, the sensitivity deterioration value between the first sensitivity and the second sensitivity is less than a preset threshold; the first sensitivity is the sensitivity of the device when working in the low-frequency channel corresponding to the WIFI 5G standard protocol, and the second sensitivity is the sensitivity of the device when working in the working frequency band corresponding to the N79 standard protocol and the low-frequency channel corresponding to the WIFI 5G standard protocol at the same time;

[0046] The sensitivity deterioration value between the third sensitivity and the fourth sensitivity is greater than or equal to a preset threshold; the third sensitivity is the sensitivity of the device when working in the high-frequency channel corresponding to the WIFI 5G standard protocol, and the fourth sensitivity is the sensitivity of the device when working in the working frequency band corresponding to the N79 standard protocol and the high-frequency channel corresponding to the WIFI 5G standard protocol at the same time.

[0047] In a specific example, the low-frequency channel corresponding to the WIFI 5G standard protocol may refer to a frequency band with a bandwidth of 20M and a center frequency of 5180MHz, or a frequency band with a bandwidth of 40M and a center frequency of 5190MHz. Figure 2 It can be seen that the N79 standard protocol has a greater interference with the WIFI 5G standard protocol with a bandwidth of 20M and a center frequency of 5180MHz, or a bandwidth of 40M and a center frequency of 5190MHz. In addition, the high-frequency channel corresponding to the WIFI 5G standard protocol can refer to a frequency band with a bandwidth of 160M and a center frequency of 5250MHz or 5570MHz. Based on the above Figure 2 It can be seen that the interference of the N79 standard protocol to the WIFI 5G standard protocol with a bandwidth of 160M and a center frequency of 5250MHz or 5570MHz is small or basically non-interfering. Based on this, in a specific example, the preset threshold can be set to 4dB.

[0048] In an optional implementation manner of the embodiment of the present application, the method of reducing the transmission power of the device in the working frequency band corresponding to the WIFI 5G standard protocol involved in the above step 102 may further include:

[0049] Step 31, when the device operates in the operating frequency band corresponding to the N79 standard protocol and the device operates in the low-frequency channel of the WIFI 5G standard protocol, reduce the transmission power of the device in the low-frequency channel corresponding to the WIFI 5G standard protocol.

[0050] Step 32, when the device operates in the operating frequency band corresponding to the N79 standard protocol, and when the device operates in the low-frequency channel of the WIFI 5G standard protocol, reduce the transmission power of the device in the frequency band corresponding to the N79 standard protocol.

[0051] It should be noted that, since the device works in the working frequency bands corresponding to the two standard protocols respectively, by reducing the transmission power of one of them, the mutual interference generated by the two standard protocols in the corresponding frequency band can be reduced. For example, if the transmission power of the WIFI 5G standard protocol in the corresponding frequency band is reduced, the interference intensity of the device working in the WIFI 5G standard protocol in the corresponding frequency band to the device working in the N79 standard protocol in the corresponding frequency band is reduced compared to before the reduction. Therefore, through the above steps 31 and 32, when the device works in the working frequency band corresponding to the N79 standard protocol and the device works in the low-frequency channel of the WIFI 5G standard protocol, the mutual interference between the two can be reduced by reducing the transmission power of the device in the frequency band corresponding to the standard protocol.

[0052] Based on the above steps 31 and 32, after reducing the transmission power of the device in the working frequency band corresponding to the WIFI 5G standard protocol, the method of the embodiment of the present application may further include:

[0053] Step 41, when the device moves out of the network corresponding to the N79 standard protocol, restore the transmission power of the device in the low-frequency channel corresponding to the WIFI 5G standard protocol;

[0054] Step 42, when the device adjusts the working frequency band corresponding to the WIFI 5G standard protocol from a low-frequency channel to a high-frequency channel, restore the transmission power of the device in the working frequency band corresponding to the WIFI 5G standard protocol.

[0055] It can be seen from the above steps 41 and 42 that when the current device only works in the working frequency band corresponding to the WIFI 5G standard protocol, the transmission power can be restored to ensure the stability of data transmission.

[0056] The present application is illustrated below with reference to specific examples of the embodiments of the present application.

[0057] Example 1

[0058] In Example 1, WIFI 5G is dynamically turned off / on depending on whether it is registered to N79. In this way, WIFI 5G can be dynamically turned on or off to ensure that N79 and WIFI5G do not interfere with each other. Figure 3 As shown, the method steps of this example include:

[0059] Step 301, confirm that the device supports both the N79 standard protocol and the WIFI 5G standard protocol;

[0060] Step 302, confirming by monitoring whether the device is registered to the network corresponding to the N79 standard protocol;

[0061] Step 303: If the device is not registered to the network corresponding to the N79 standard protocol, confirm whether the device's WIFI 5G function needs to be turned on;

[0062] Step 304: If it is confirmed that the WIFI 5G function needs to be turned on, turn on the WIFI 5G function;

[0063] Step 305: If it is confirmed that WIFI 5G does not need to be turned on, turn off the WIFI 5G function;

[0064] Step 306: If the device has been registered to N79, turn off the WIFI 5G function to ensure that there is no mutual interference.

[0065] Through the above steps 301 to 306, if the device supports both the N79 standard protocol and the WIFI 5G standard protocol, if the device is registered to the network corresponding to the N79 standard protocol, the WIFI 5G function needs to be automatically turned off to ensure that no mutual interference occurs. If it is not registered to the network corresponding to the N79 standard protocol, it can be determined whether to turn on or off the WIFI 5G function of the device according to the actual situation.

[0066] Example 2

[0067] In Example 2, it is currently detected that the device is registered to the network corresponding to the N79 standard protocol and the device is also working on the low-frequency channel corresponding to the WIFI 5G standard protocol. Then the WIFI 5G is directly switched to the high-frequency channel to ensure that N79 and WIFI5G no longer interfere with each other or the interference is small. Figure 4 As shown, the method steps of this example include:

[0068] Step 401, confirm that the device supports both the N79 standard protocol and the WIFI 5G standard protocol;

[0069] Step 402, confirming by monitoring whether the device is registered to the working frequency band corresponding to the N79 standard protocol;

[0070] Step 403: If the device is registered to the network corresponding to the N79 standard protocol, confirm whether the device is working in the low-frequency channel of the WIFI 5G standard protocol;

[0071] Step 404: If it is confirmed that the device is operating in a low-frequency channel in the WIFI 5G standard protocol, the device is switched to a high-frequency channel operating in the WIFI 5G standard protocol.

[0072] like Figure 2As shown, when the device operates at a frequency below 5300GHz of WIFI 5G, if the device is registered to the N79 standard protocol at this time, the interference of the device operating at the frequency band corresponding to the N79 standard protocol and the WIFI 5G standard protocol is obvious. When the device operates at a frequency of 5300GHz and above of WIFI 5G, if the device is registered to the N79 standard protocol at this time, the interference of the device operating at the same time in the frequency band corresponding to the N79 standard protocol and the WIFI 5G standard protocol is small or there is no interference. Based on this, in the embodiment of the present application, the frequency below 5300GHz in the frequency band corresponding to WIFI 5G can be a low-frequency channel, and the frequency above 5300GHz can be a high-frequency channel. Therefore, when the device operates at the frequency band corresponding to the N79 standard protocol and the WIFI 5G standard protocol at the same time, it is necessary to adjust the device to operate in the frequency band corresponding to the WIFI 5G standard protocol to reduce the mutual interference caused by operating at the same time in the frequency band corresponding to the N79 standard protocol and the WIFI 5G standard protocol.

[0073] Example 3

[0074] In Example 3, based on two conditions (whether registered to the N79 & WIFI 5G working channel), the WIFI Tx power is dynamically reduced / restored to reduce the mutual interference caused by the device working in the frequency bands corresponding to the N79 standard protocol and the WIFI 5G standard protocol at the same time. Figure 5 As shown, the method steps of this example include:

[0075] Step 501, confirm that the device supports both the N79 standard protocol and the WIFI 5G standard protocol;

[0076] Step 502, confirming whether the device is registered to the N79 standard protocol network by monitoring;

[0077] Step 503, if the device is registered to the network of the N79 standard protocol, confirm whether the device is working in the low-frequency channel of the WIFI 5G standard protocol;

[0078] Step 504: If it is confirmed that the device is operating in a low-frequency channel of the WIFI 5G standard protocol, the Tx power of the device in the frequency band corresponding to the WIFI 5G standard protocol is reduced;

[0079] Step 505: If it is confirmed that the device has moved out of the network corresponding to the N79 standard protocol and the device switches from working on a WIFI 5G low-frequency channel to working on a high-frequency channel, the Tx power of the device in the frequency band corresponding to the WIFI 5G standard protocol is restored.

[0080] It should be noted that Tx power is also the transmit power of WIFI. In the embodiment of the present application, the specific Tx power can be determined according to actual needs or empirical values. For example, in actual situations, the mutual interference situation can be analyzed by gradually reducing the transmit power of WIFI 5G, and an acceptable value of mutual interference can be determined from the process of gradually reducing the Tx power. Then, the Tx power reduction value at this time can be the Tx power reduction value in the embodiment of the present application. Of course, the above is only an example, because reducing the Tx power can reduce mutual interference under normal circumstances, so the specific Tx power reduction value can be set accordingly according to the actual situation.

[0081] In addition, when WIFI 5G works in a high-frequency channel, mutual interference is small or non-existent, so there is no need to reduce the transmission power of WIFI 5G. The recovery here is to cancel the reduction of WIFI transmission power, no longer control the WIFI transmission power, and work according to the maximum transmission power supported by the device.

[0082] Corresponding to the above Figure 1 , the embodiment of the present application also provides an anti-interference device, such as Figure 6 As shown, the device comprises:
