[0027] As mentioned in the background technology, the USB data transmission process in the prior art interferes with WiFi communication and LTE communication. In order to solve the above problem, in a typical embodiment of the present application, a method, device, computer-readable storage medium, processor and system for adjusting the USB encoding method are provided.

[0028] According to an embodiment of the present application, a method for adjusting a USB encoding mode is provided.

[0029] Figure 1 FIG. 1 is a flow chart of a method for adjusting the USB encoding method according to an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0030] Step S101, obtaining at least one of a WiFi parameter and an LTE parameter of a smart device, wherein the smart device is a device that supports USB data transmission and has at least one of the following functions: a WiFi function and an LTE network function, wherein the WiFi parameter includes WiFi power and WiFi frequency band, and the LTE parameter includes LTE power and LTE frequency band;

[0031] Step S102, adjusting the USB encoding method of the smart device based on at least one of the following: whether the WiFi power is greater than a first threshold, whether the LTE power is greater than a second threshold, whether the WiFi frequency band is within a first predetermined range or a second predetermined range, and whether the LTE frequency band is within a third predetermined range or a fourth predetermined range.

[0032] In the above-mentioned USB encoding mode adjustment method, at least one of WiFi parameters and LTE parameters of a smart device is first obtained. The smart device is a device that supports USB data transmission and has at least one of the following functions: WiFi function and LTE network function. The WiFi parameters include WiFi power and WiFi frequency band, and the LTE parameters include LTE power and LTE frequency band. Then, the USB encoding mode of the smart device is adjusted based on at least one of the following: whether the WiFi power is greater than a first threshold, whether the LTE power is greater than a second threshold, whether the WiFi frequency band is within a first predetermined range or a second predetermined range, and whether the LTE frequency band is within a third predetermined range or a fourth predetermined range. By determining the WiFi parameters and LTE parameters of the smart device, the method can determine the WiFi usage requirements of the smart device and the environmental conditions of the LTE network. The USB encoding mode of the smart device is then adjusted based on the WiFi usage requirements and the environmental conditions of the LTE network, thereby maintaining a good communication state for WiFi or LTE communication. This solves the problem of interference caused by USB data transmission on WiFi and LTE communications in the prior art.

[0033] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0034] In actual applications, the USB 3.0 protocol generally requires USB to use SSC technology, which expands the USB 3.0 spectrum in the 2.5 GHz band to close to 2.4 GHz. The signal is not completely distributed in the 2.4 GHz band, which causes interference between LTE and WiFi communications in the 2.4 GHz band.

[0035] In one embodiment of the present application, the above-mentioned encoding method includes at least one of the following: NRZ encoding method, PAM4 encoding method and PAM16 encoding method.

[0036] In practical applications, PAM4 encoding reduces the USB baud rate to 1.25G, while PAM16 encoding reduces it to 625M. PAM4 encoding introduces delays during the encoding and forwarding process, shortening the signal's transmission distance. However, when Wi-Fi devices are in close proximity to these smart devices, NRZ encoding can be used to eliminate the delay introduced by USB encoding and forwarding.

[0037] In another embodiment of the present application, obtaining the WiFi parameters includes: obtaining the WiFi power and the WiFi frequency band when the smart device has a WiFi connection with other devices and the smart device does not have LTE communication with the base station; obtaining the LTE parameters includes: obtaining the LTE power and the LTE frequency band when the smart device has LTE communication with the base station and the smart device does not have a WiFi connection with the other devices; obtaining the WiFi parameters and the LTE parameters includes: obtaining the WiFi power, the WiFi frequency band, the LTE power, and the LTE frequency band when the smart device has a WiFi connection with the other devices and the smart device has LTE communication with the base station. The WiFi usage requirements of the smart device can be determined based on the WiFi power and WiFi frequency band of the smart device, and the environmental conditions of the LTE network can be determined based on the LTE power and LTE frequency band of the smart device. The WiFi power and WiFi frequency band can be obtained when the smart device has a WiFi connection with other devices, and the LTE power and LTE frequency band can be obtained when the smart device has LTE communication with the base station.

[0038] In the absence of LTE communication, only the impact of the USB encoding scheme on WiFi transmission needs to be considered. To determine the WiFi transmission rate of the smart device and thereby adjust the USB encoding scheme (which does not affect the rate) based on the WiFi transmission rate, in another embodiment of the present application, the USB encoding scheme of the smart device is adjusted based on at least one of the following: whether the WiFi power is greater than a first threshold, whether the LTE parameter is greater than a second threshold, whether the WiFi frequency band is within a first predetermined range or a second predetermined range, and whether the LTE frequency band is within a third predetermined range or a fourth predetermined range. The method includes: when the smart device is connected to another device via WiFi, determining whether the WiFi power is greater than the first threshold; if the WiFi power is less than the first threshold, adjusting the USB encoding scheme of the smart device to the NRZ encoding scheme; and when the WiFi power is greater than or equal to the first threshold, adjusting the USB encoding scheme of the smart device based on whether the WiFi frequency band is within the first predetermined range or the second predetermined range.

[0039] Specifically, when the WiFi power is less than the first threshold, it indicates that there is a WiFi communication device relatively close to the smart device, and the USB interference with the WiFi transmission is relatively small. The USB encoding method of the smart device can be adjusted to NRZ encoding. When the WiFi power is greater than the first threshold, it indicates that there is a WiFi communication device relatively far away from the smart device. In this case, the WiFi transmission rate of the smart device is relatively low. If interfered with by the USB, the WiFi transmission rate will be further reduced. Therefore, it is necessary to determine the WiFi frequency band at this time to confirm whether the WiFi communication will be interfered with by the USB.

[0040] In another embodiment of the present application, adjusting the USB encoding mode of the smart device based on whether the WiFi frequency band is within the first predetermined range or the second predetermined range includes: adjusting the USB encoding mode of the smart device to the PAM4 encoding mode when the WiFi frequency band is within the first predetermined range; and adjusting the USB encoding mode of the smart device to the NRZ encoding mode when the WiFi frequency band is within the second predetermined range. The WiFi frequency band can further reduce interference from USB to WiFi transmission.

[0041] Specifically, the USB protocol generally requires that the USB adopt SSC technology to expand the USB spectrum in the 2.5GHz frequency band to approach 2.4GHz. The above-mentioned first predetermined range may include 2.4GHz. When the WiFi frequency band is 2.4GHz, the USB encoding method of the above-mentioned smart device is adjusted to the above-mentioned PAM4 encoding method, and the USB baud rate is changed to avoid the WiFi interference frequency band of 2.4GHz, thereby ensuring normal WiFi communication. The above-mentioned second predetermined range may include 5GHz. When the WiFi frequency band is 5GHz, USB will not interfere with it, so the encoding method is adjusted to NRZ encoding.

[0042] In the absence of a WiFi connection, only the impact of the USB encoding method on LTE transmission needs to be considered. In order to determine the LTE communication rate of the smart device, and thereby adjust the USB encoding method that does not affect its rate according to the LTE communication rate, in another embodiment of the present application, the USB encoding method of the smart device is adjusted according to at least one of the following: whether the WiFi power is greater than a first threshold, whether the LTE parameter is greater than a second threshold, whether the WiFi frequency band is within the first predetermined range or the second predetermined range, and whether the LTE frequency band is within the third predetermined range or the fourth predetermined range, including: when the smart device has LTE communication with the base station and there is no WiFi between the smart device and other devices, If the LTE power is greater than the second threshold, the smart device determines whether the LTE power is greater than the second threshold. If the LTE power is less than the second threshold, the USB encoding mode of the smart device is adjusted to the NRZ encoding mode. If the LTE power is greater than or equal to the second threshold, the smart device determines whether the LTE frequency band is within the third predetermined range or the fourth predetermined range. If the LTE frequency band is within the third predetermined range, the USB encoding mode of the smart device is adjusted to the PAM4 encoding mode. If the LTE frequency band is within the fourth predetermined range, the USB encoding mode of the smart device is adjusted to one of the NRZ encoding mode and the PAM16 encoding mode. To further reduce the impact of USB transmission on LTE communication, the USB encoding mode is adjusted according to the LTE frequency band.

[0043] Specifically, when the LTE power is less than the second threshold, it indicates that the smart device is relatively close to the base station. Adjusting the USB encoding method to NRZ will not increase USB communication latency. When the LTE power is greater than or equal to the second threshold, the impact of the LTE frequency band must also be considered. The third predetermined range may include 2.4 GHz. If the LTE operating frequency band is at 2.4 GHz, the USB encoding method of NRZ will interfere with it. Adjusting the USB encoding method to PAM4 and reducing the baud rate to 1.25 GHz can reduce interference. The fourth predetermined range may include 1 GHz. If the LTE operating frequency band is at 1 GHz, it is close to 1.25 GHz and susceptible to interference. Therefore, adjusting the USB encoding method to PAM16 and reducing the baud rate to 625 MHz, or adjusting the USB encoding method to NRZ, can reduce interference.

[0044] In another embodiment of the present application, adjusting the USB encoding mode of the smart device based on at least one of the following: whether the WiFi power is greater than a first threshold, whether the LTE parameter is greater than a second threshold, whether the WiFi frequency band is within a first predetermined range or a second predetermined range, and whether the LTE frequency band is within a third predetermined range or a fourth predetermined range includes: when the smart device has a WiFi connection with another device and the smart device has LTE communication with a base station, determining whether the WiFi power is greater than the first threshold and whether the WiFi frequency band is within the first predetermined range or the second predetermined range; when the WiFi power is less than the first threshold, or when the WiFi power is greater than or equal to the first threshold and the WiFi frequency band is within the second predetermined range, adjusting the USB encoding mode of the smart device based on at least one of the following: whether the LTE parameter is greater than the second threshold and whether the LTE frequency band is within the third predetermined range or the fourth predetermined range; and when the WiFi power is greater than or equal to the first threshold and the WiFi frequency band is within the first predetermined range, adjusting the USB encoding mode of the smart device based on at least one of the following: whether the LTE parameter is greater than the second threshold and whether the LTE frequency band is within the third predetermined range or the fourth predetermined range. When both WiFi connection and LTE communication exist, both WiFi parameters and LTE parameters need to be considered to minimize the impact of USB transmission on WiFi transmission and LTE transmission.

[0045] To further reduce interference caused by USB transmission on WiFi transmission and LTE transmission, in another embodiment of the present application, when the WiFi power is less than the first threshold, or when the WiFi power is greater than or equal to the first threshold and the WiFi frequency band is within the second predetermined range, the USB encoding mode of the smart device is adjusted based on at least one of the following: whether the LTE parameter is greater than the second threshold, and whether the LTE frequency band is within the third predetermined range or the fourth predetermined range. The adjustment includes: when the LTE power is less than the second threshold, adjusting the USB encoding mode of the smart device to the NRZ encoding mode; when the LTE power is greater than or equal to the second threshold, determining whether the LTE frequency band is within the third predetermined range or the fourth predetermined range; when the LTE frequency band is within the third predetermined range, adjusting the USB encoding mode of the smart device to the PAM4 encoding mode; and when the LTE frequency band is within the fourth predetermined range, adjusting the USB encoding mode of the smart device to one of the NRZ encoding mode and the PAM16 encoding mode.

[0046] In order to further reduce the interference caused by USB transmission on WiFi transmission and LTE transmission, in another embodiment of the present application, when the above-mentioned WiFi power is greater than or equal to the above-mentioned first threshold and the above-mentioned WiFi frequency band is within the above-mentioned first predetermined range, the USB encoding mode of the above-mentioned smart device is adjusted according to at least one of the following: whether the above-mentioned LTE parameter is greater than the above-mentioned second threshold, whether the above-mentioned LTE frequency band is within the above-mentioned third predetermined range or the above-mentioned fourth predetermined range, including: when the above-mentioned LTE power is less than the above-mentioned second threshold, adjusting the USB encoding mode of the above-mentioned smart device to the above-mentioned PAM4 encoding mode; when the above-mentioned LTE power is greater than or equal to the above-mentioned second threshold, determining whether the above-mentioned LTE frequency band is within the above-mentioned third predetermined range or the above-mentioned fourth predetermined range; when the above-mentioned LTE frequency band is within the above-mentioned third predetermined range, adjusting the USB encoding mode of the above-mentioned smart device to the above-mentioned PAM4 encoding mode; when the above-mentioned LTE frequency band is within the above-mentioned third predetermined range, adjusting the USB encoding mode of the above-mentioned smart device to the above-mentioned PAM16 encoding mode.

[0047] The present application also provides an apparatus for adjusting a USB encoding method. It should be noted that the apparatus for adjusting a USB encoding method according to the present application can be used to execute the method for adjusting a USB encoding method according to the present application. The apparatus for adjusting a USB encoding method according to the present application is described below.

[0048] Figure 2 Schematic diagram of a device for adjusting the USB encoding method according to an embodiment of the present application. Figure 2 As shown, the device includes:

[0049] an acquiring unit 10, configured to acquire at least one of a WiFi parameter and an LTE parameter of a smart device, wherein the smart device is a device that supports USB data transmission and has at least one of the following functions: a WiFi function and an LTE network function, wherein the WiFi parameter includes WiFi power and WiFi frequency band, and the LTE parameter includes LTE power and LTE frequency band;

[0050] The adjustment unit 20 is configured to adjust the USB encoding method of the smart device based on at least one of the following: whether the WiFi power is greater than a first threshold, whether the LTE power is greater than a second threshold, whether the WiFi frequency band is within a first predetermined range or a second predetermined range, and whether the LTE frequency band is within a third predetermined range or a fourth predetermined range.

[0051] In the above-mentioned USB encoding mode adjustment device, the acquisition unit acquires at least one of WiFi parameters and LTE parameters of a smart device. The smart device supports USB data transmission and has at least one of the following functions: WiFi function and LTE network function. The WiFi parameters include WiFi power and WiFi frequency band, and the LTE parameters include LTE power and LTE frequency band. The adjustment unit adjusts the USB encoding mode of the smart device based on at least one of the following: whether the WiFi power is greater than a first threshold, whether the LTE power is greater than a second threshold, whether the WiFi frequency band is within a first predetermined range or a second predetermined range, and whether the LTE frequency band is within a third predetermined range or a fourth predetermined range. By determining the WiFi parameters and LTE parameters of the smart device, the device can determine the WiFi usage requirements of the smart device and the environmental conditions of the LTE network. The device then adjusts the USB encoding mode of the smart device based on the WiFi usage requirements and the environmental conditions of the LTE network, thereby maintaining a good communication state for WiFi or LTE communication. This solves the problem of interference between WiFi and LTE communications caused by USB data transmission in the prior art.

[0052] In actual applications, the USB 3.0 protocol generally requires USB to use SSC technology, which expands the USB 3.0 spectrum in the 2.5 GHz band to close to 2.4 GHz. The signal is not completely distributed in the 2.4 GHz band, which causes interference between LTE and WiFi communications in the 2.4 GHz band.

[0053] In one embodiment of the present application, the above-mentioned encoding method includes at least one of the following: NRZ encoding method, PAM4 encoding method and PAM16 encoding method.

[0054] In practical applications, PAM4 encoding reduces the USB baud rate to 1.25G, while PAM16 encoding reduces it to 625M. PAM4 encoding introduces delays during the encoding and forwarding process, shortening the signal's transmission distance. However, when Wi-Fi devices are in close proximity to these smart devices, NRZ encoding can be used to eliminate the delay introduced by USB encoding and forwarding.

[0055] In another embodiment of the present application, the acquisition unit includes a first acquisition module, a second acquisition module, and a third acquisition module, wherein the first acquisition module is configured to acquire the WiFi power and the WiFi frequency band when the smart device is connected to another device via WiFi and the smart device is not in LTE communication with the base station; the second acquisition module is configured to acquire the LTE power and the LTE frequency band when the smart device is in LTE communication with the base station and the smart device is not in WiFi connection with the other device; and the third acquisition module is configured to acquire the WiFi power, the WiFi frequency band, the LTE power, and the LTE frequency band when the smart device is connected to the other device and the smart device is in LTE communication with the base station. The WiFi usage requirement of the smart device can be determined based on the WiFi power and WiFi frequency band of the smart device, and the environmental status of the LTE network can be determined based on the LTE power and LTE frequency band of the smart device. The WiFi power and WiFi frequency band can be acquired when the smart device is connected to another device via WiFi, and the LTE power and LTE frequency band can be acquired when the intelligent device is in LTE communication with the base station.

[0056] In the absence of LTE communication, only the impact of the USB encoding method on WiFi transmission needs to be considered. In order to determine the WiFi transmission rate of the smart device and adjust the USB encoding method that does not affect its rate according to the WiFi transmission rate, in another embodiment of the present application, the above-mentioned adjustment unit includes a first determination module, a first adjustment module and a second adjustment module, wherein the above-mentioned first determination module is used to determine whether the above-mentioned WiFi power is greater than the above-mentioned first threshold when the above-mentioned smart device has a WiFi connection with other devices; the above-mentioned first adjustment module is used to adjust the USB encoding method of the above-mentioned smart device to the above-mentioned NRZ encoding method when the above-mentioned WiFi power is less than the above-mentioned first threshold; the above-mentioned second adjustment module is used to adjust the USB encoding method of the above-mentioned smart device according to whether the above-mentioned WiFi frequency band is within the above-mentioned first predetermined range or the above-mentioned second predetermined range when the above-mentioned WiFi power is greater than or equal to the above-mentioned first threshold.

[0057] Specifically, when the WiFi power is less than the first threshold, it indicates that there is a WiFi communication device relatively close to the smart device, and the USB interference with the WiFi transmission is relatively small. The USB encoding method of the smart device can be adjusted to NRZ encoding. When the WiFi power is greater than the first threshold, it indicates that there is a WiFi communication device relatively far away from the smart device. In this case, the WiFi transmission rate of the smart device is relatively low. If interfered with by the USB, the WiFi transmission rate will be further reduced. Therefore, it is necessary to determine the WiFi frequency band at this time to confirm whether the WiFi communication will be interfered with by the USB.

[0058] In another embodiment of the present application, the second adjustment module includes a first adjustment submodule and a second adjustment submodule. The first adjustment submodule is configured to adjust the USB encoding mode of the smart device to the PAM4 encoding mode when the WiFi frequency band is within the first predetermined range; and the second adjustment submodule is configured to adjust the USB encoding mode of the smart device to the NRZ encoding mode when the WiFi frequency band is within the second predetermined range. The use of the WiFi frequency band can further reduce interference from USB to WiFi transmission.

[0059] Specifically, the USB protocol generally requires that the USB adopt SSC technology to expand the USB spectrum in the 2.5GHz frequency band to approach 2.4GHz. The above-mentioned first predetermined range may include 2.4GHz. When the WiFi frequency band is 2.4GHz, the USB encoding method of the above-mentioned smart device is adjusted to the above-mentioned PAM4 encoding method, and the USB baud rate is changed to avoid the WiFi interference frequency band of 2.4GHz, thereby ensuring normal WiFi communication. The above-mentioned second predetermined range may include 5GHz. When the WiFi frequency band is 5GHz, USB will not interfere with it, so the encoding method is adjusted to NRZ encoding.

[0060] In the absence of a WiFi connection, it is only necessary to consider the impact of the USB encoding method on LTE transmission. In order to determine the LTE communication rate of the smart device, the USB encoding method that does not affect its rate is adjusted according to the LTE communication rate. In another embodiment of the present application, the second adjustment unit includes a second determination module, a third adjustment module, a fourth adjustment module, a fourth determination module and a fifth adjustment module, wherein the second determination submodule is used to determine whether the LTE power is greater than the second threshold when there is LTE communication between the smart device and the base station and there is no WiFi connection between the smart device and other devices; the third adjustment module is used to determine whether the LTE power is greater than the second threshold when the LTE power is less than the second threshold; When the second threshold is reached, the USB encoding scheme of the smart device is adjusted to the NRZ encoding scheme. The third determination module is configured to determine whether the LTE frequency band is within the third predetermined range or the fourth predetermined range when the LTE power is greater than or equal to the second threshold. The fourth adjustment module is configured to adjust the USB encoding scheme of the smart device to the PAM4 encoding scheme when the LTE frequency band is within the third predetermined range. The fifth adjustment module is configured to adjust the USB encoding scheme of the smart device to one of the NRZ encoding scheme and the PAM16 encoding scheme when the LTE frequency band is within the fourth predetermined range. To further reduce the impact of USB transmission on LTE communication, the USB encoding scheme is adjusted based on the LTE frequency band.

[0061] Specifically, when the LTE power is less than the second threshold, it indicates that the smart device is relatively close to the base station. Adjusting the USB encoding method to NRZ will not increase USB communication latency. When the LTE power is greater than or equal to the second threshold, the impact of the LTE frequency band must also be considered. The third predetermined range may include 2.4 GHz. If the LTE operating frequency band is at 2.4 GHz, the USB encoding method of NRZ will interfere with it. Adjusting the USB encoding method to PAM4 and reducing the baud rate to 1.25 GHz can reduce interference. The fourth predetermined range may include 1 GHz. If the LTE operating frequency band is at 1 GHz, it is close to 1.25 GHz and susceptible to interference. Therefore, adjusting the USB encoding method to PAM16 and reducing the baud rate to 625 MHz, or adjusting the USB encoding method to NRZ, can reduce interference.

[0062] In another embodiment of the present application, the adjustment unit includes a fourth determination module, a sixth adjustment module, and a seventh adjustment module, wherein the fourth determination module is configured to determine whether the WiFi power is greater than the first threshold and whether the WiFi frequency band is within the first predetermined range or the second predetermined range when the smart device has a WiFi connection with another device and the smart device has LTE communication with a base station; the sixth adjustment module is configured to adjust the USB encoding method of the smart device based on at least one of the following when the WiFi power is less than the first threshold, or when the WiFi power is greater than or equal to the first threshold and the WiFi frequency band is within the second predetermined range: whether the LTE parameter is greater than the second threshold, whether the LTE frequency band is within the third predetermined range, or whether the LTE frequency band is within the fourth predetermined range; and the seventh adjustment module is configured to adjust the USB encoding method of the smart device based on at least one of the following when the WiFi power is greater than or equal to the first threshold and the WiFi frequency band is within the first predetermined range: whether the LTE parameter is greater than the second threshold, whether the LTE frequency band is within the third predetermined range, or whether the LTE frequency band is within the fourth predetermined range. When both WiFi connection and LTE communication exist, both WiFi parameters and LTE parameters need to be considered to minimize the impact of USB transmission on WiFi transmission and LTE transmission.

[0063] In order to further reduce the interference caused by USB transmission to WiFi transmission and LTE transmission, in another embodiment of the present application, the above-mentioned sixth adjustment module includes a third adjustment submodule, a first determination submodule, a fourth adjustment submodule and a fifth adjustment submodule, wherein the above-mentioned third adjustment submodule is used to adjust the USB encoding mode of the above-mentioned smart device to the above-mentioned NRZ encoding mode when the above-mentioned LTE power is less than the above-mentioned second threshold; the above-mentioned first determination submodule is used to determine whether the above-mentioned LTE frequency band is within the above-mentioned third predetermined range or the above-mentioned fourth predetermined range when the above-mentioned LTE power is greater than or equal to the above-mentioned second threshold; the above-mentioned fourth adjustment subunit is used to adjust the USB encoding mode of the above-mentioned smart device to the above-mentioned PAM4 encoding mode when the above-mentioned LTE frequency band is within the above-mentioned third predetermined range; the above-mentioned fifth adjustment subunit is used to adjust the USB encoding mode of the above-mentioned smart device to one of the above-mentioned NRZ encoding mode and the above-mentioned PAM16 encoding mode when the above-mentioned LTE frequency band is within the above-mentioned fourth predetermined range.

[0064] In order to further reduce the interference caused by USB transmission to WiFi transmission and LTE transmission, in another embodiment of the present application, the above-mentioned seventh adjustment module includes a sixth adjustment submodule, a second determination submodule, a seventh adjustment submodule and an eighth adjustment submodule, wherein the above-mentioned sixth adjustment submodule is used to adjust the USB encoding mode of the above-mentioned smart device to the above-mentioned PAM4 encoding mode when the above-mentioned LTE power is less than the above-mentioned second threshold; the above-mentioned second determination submodule is used to determine whether the above-mentioned LTE frequency band is within the above-mentioned third predetermined range or the above-mentioned fourth predetermined range when the above-mentioned LTE power is greater than or equal to the above-mentioned second threshold; the above-mentioned seventh adjustment submodule is used to adjust the USB encoding mode of the above-mentioned smart device to the above-mentioned PAM4 encoding mode when the above-mentioned LTE frequency band is within the above-mentioned third predetermined range; and the above-mentioned eighth adjustment submodule is used to adjust the USB encoding mode of the above-mentioned smart device to the above-mentioned PAM16 encoding mode when the above-mentioned LTE frequency band is within the above-mentioned fourth predetermined range.
