[0002] With the diversification of communication technologies, such as the Global Positioning System (GPS) and Near Field Communication (NFC), the same portable wearable device often needs to integrate multiple communication circuits and have multiple RF modules. In wireless communications, there are strict requirements for interference with adjacent channels, that is, the frequency band of the modulated signal must be strictly controlled within its own channel and is not allowed to leak into adjacent channels.

[0003] Traditional channels use single-link transmission technology, but single-link transmission technology requires frequency screening through the bandpass filter inside the duplexer to achieve interaction in the corresponding frequency band. However, due to hardware process limitations, the screening frequency of the bandpass filter inside the duplexer cannot obtain the ideal frequency range, resulting in adjacent channel interference, making it impossible to achieve ideal bandpass filtering.

The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute the command sent by the processor 110.

Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the smart terminal, which is not limited here.

[0058] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA and future new network systems (such as 5G), etc., without limitation here.

[0059] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0060] First embodiment Figure 3 FIG. 1 is a flow chart of a channel control method according to the first embodiment. Figure 3 As shown, a channel control method of the present application comprises the following steps: S101: In response to a first operation, controlling a first channel to start, and detecting coupling energy output by the first channel; S102: When the coupling energy meets a first preset condition, control the first channel to stop or switch processing.

[0061] Traditional channels use single-link transmission, but the power in the channel will be affected by interference such as adjacent channel out-of-band spurious during transmission. In particular, when the frequency of interaction in the channel is at the edge, the interference from the adjacent channel will be aggravated. However, through this solution, the channel transmission situation can be monitored in real time, and when the coupling energy in the channel reaches the threshold, the current channel is switched / stopped immediately. The coupling energy in this embodiment is the energy processed by directional coupling of the coupler.

[0062] Optionally, the first operation in step S101 at least includes: Receive a transmission instruction; control the transmission of the first power according to the transmission instruction, so as to control the first channel to start and transmit the first power, output the second power and couple energy.

[0063] Optionally, satisfying the first preset condition in step S102 includes at least one of the following: The change value of the coupling energy is higher than a preset first threshold value; the coupling energy is lower than a preset second threshold value.

[0064] It is further explained that the first operation in this embodiment is used to receive a transmission instruction, and after parsing the corresponding frequency band range of the first power according to the transmission instruction, control the transmission of the first power in the corresponding frequency band range. When the first power transmitted by the first channel is within the corresponding frequency band range, the coupling energy outputted by it is also within a stable range. However, when the first power changes due to the interference of adjacent channels during the transmission process, the generated coupling energy will also change. In some embodiments, the greater the interference effect, the greater the coupling energy effect, and the lower the coupling energy value. This embodiment makes a judgment from at least two directions. When the coupling energy is lower than the preset second threshold value, it is judged that the coupling energy meets the first preset condition. When the change value of the coupling energy is higher than the preset first threshold value, it indicates that the coupling energy has dropped significantly, and it is judged that the coupling energy meets the first preset condition.

[0065] Optionally, a channel control method provided by this embodiment further includes: S103: In response to the detected coupling energy not satisfying the first preset condition and the second power satisfying the second preset condition, controlling the second power output process.

[0066] Optionally, after step S103, the method further includes: S104: in response to the second power not satisfying the second preset condition, obtaining compensation power and triggering a compensation instruction; The transmission compensation power is controlled according to the compensation instruction, and the compensation power is transmitted through the first channel.

[0067] Among them, satisfying the second preset condition in this embodiment includes: the second power is within the corresponding frequency band range of the first power.

[0068] The channel control method of the present application controls the first channel to start in response to a first operation, and detects the coupling energy output by the first channel; when the coupling energy meets a first preset condition, controls the first channel to stop or switch processing. The technical solution of the present application controls the channel operation according to the coupling energy output by the channel, so as to ensure the stability of the transmission frequency interaction.

[0069] Second embodiment Figure 4 FIG. 1 is a schematic diagram of the structure of a channel control module according to the second embodiment. Figure 4 As shown, a channel control module of the present application includes: A controller 10 and a first channel 20. The controller 10 is connected to the first channel 20 and is used to control the first channel 20 to start in response to triggering a first operation, and detect the coupling energy output by the first channel 20. When it is detected that the coupling energy meets a first preset condition, the first channel 20 is controlled to stop or switch processing.

[0070] This embodiment adopts a channel control module, and can control the working state of the first channel 20 according to the coupling energy output by the first channel 20.

[0071] Figure 5 It is a schematic structural diagram of a channel control module according to the second embodiment.

[0072] Optionally, the first channel 20 includes a transmitter 21, and after receiving a transmission instruction from the controller 10 through the transmitter 21, the first power is transmitted according to the transmission instruction to control the start-up of the first channel 20.

[0073] To further illustrate, the transmitter 21 in this embodiment transmits the first power of the corresponding frequency band according to the transmission instruction. The transmitter 21 serves as the starting point of the first channel 20 and transmits the first power of the corresponding frequency band.

[0074] Optionally, the first channel 20 includes a directional coupler 24, which receives the processed first power through the directional coupler 24 and outputs the second power and coupling energy. Further, the directional coupler 24 is connected to the controller 10 and the transmitter 21, and outputs the second power and coupling energy after coupling processing the processed first power. Further, after the directional coupler 24 in the first channel outputs the second power, it feeds back the coupling energy to the controller 10 accordingly, so that the controller 10 controls the working state of the first channel according to the coupling energy.

[0075] Further, in this embodiment, the components of the first channel 20 include, in addition to the transmitter 21 and the directional coupler 24, a radio frequency amplifier 22 and a duplexer 23. The first channel 20 includes the transmitter 21, the radio frequency amplifier 22, the duplexer 23 and the directional coupler 24 in order according to the power transmission direction.

[0076] Optionally, the first channel 20 includes a radio frequency amplifier 22 , and the radio frequency amplifier 22 is connected to the transmitter 21 to amplify the first power transmitted by the transmitter 21 .

[0077] Optionally, the first channel 20 includes a duplexer 23, the input end of the duplexer 23 is connected to the radio frequency amplifier 22, and the output end is connected to the directional coupler 24. The duplexer 23 has a built-in bandpass filter, and the amplified first power is filtered by the bandpass filter so that the directional coupler 24 couples the first power within the threshold range. The first power is filtered by the bandpass filter to improve the coupling accuracy and coupling efficiency of the directional coupler 24.

[0078] For further explanation, refer to the attached Figure 6 As shown, Figure 6 2 is a schematic diagram of the structure of a traditional channel control module according to the second embodiment. The channel elements required for the traditional transmission link include at least: a transmitter 21, a radio frequency amplifier 22, and a duplexer 23. The power emitted by the transmitter 21 is amplified to the target power by the radio frequency amplifier 22, and then directly output after being filtered by the bandpass filter inside the duplexer 23 to reach the corresponding frequency band range. However, due to the limitation of hardware technology, the bandpass filter inside the duplexer 23 cannot achieve the ideal pass filter effect. Please refer to the attached Figure 7 As shown, Figure 7It is a comparison diagram of the ideal bandpass filtering effect and the actual bandpass filtering effect shown in the second embodiment. The existing hardware process causes the screening frequency of the duplexer 23 to be unable to obtain the ideal frequency range, thereby deriving ACLR (Adjacent Channel Leakage Ratio), and the transmission channel will be interfered by the adjacent channel out-of-band spurious, especially when it is at the edge of the channel and / or the edge of the corresponding frequency range, the adjacent channel interference will be aggravated. Based on this, in this embodiment, on the basis of the traditional channel, the bandpass filter in the duplexer adopts a ladder filter, and a directional coupler is added at the end of the channel to perform channel monitoring.

[0079] Based on this, the bandpass filter in the duplexer 23 of this embodiment adopts a trapezoidal filter, which allows waves in a specific frequency band to pass through while shielding other frequency bands. After the first power is filtered, the energy of the output first power will be greatly weakened, so that the coupling energy output by the directional coupler will also be greatly reduced. However, the trapezoidal filter improves the accuracy of the coupling process, and only monitors and judges the coupling energy of the first power in the corresponding frequency band range. When the coupling energy drops significantly, the directional coupler 24 sends an instruction to the controller 10 to stop or switch the current first channel. Specifically, the controller 10 controls the transmitter to start or stop or switch the process according to the coupling energy transmitted by the directional coupler 24.

[0080] The coupler is a universal microwave / millimeter wave component. The coupler can be used to isolate, separate and mix signals, and can realize power monitoring, source output power stabilization, signal source isolation, transmission and reflection sweep frequency testing, etc. The main technical indicators are directivity, standing wave ratio, coupling degree, and insertion loss. Compared with the coupler, the directional coupler allows a certain amount of energy transmission without affecting the overall working performance.

[0081] Optionally, refer to the attached Figure 8 As shown, a schematic diagram of the structure of a directional coupler according to the second embodiment is shown. The directional coupler 24 includes a main line and a sub-line, and the main line and the sub-line are coupled through holes, slits, and gaps. The directional coupler 24 feeds back coupling energy to the controller, outputs the second power to the outside, and transmits overflow power to the transmitter 21. Therefore, part of the power input from the "1" on the main line end of the directional coupler 24 will be coupled to the sub-line. Based on the interference or superposition characteristics of the waves, the power is transmitted only in one direction along the sub-line (called "forward"), and almost no power is transmitted in the other direction (called "reverse"). Among them, the coupling energy of the directional coupler 24 includes indicators: direct-through parameter, coupling parameter, isolation parameter, reflection parameter, and these indicators are obtained by calculating the scattering matrix.

[0082] Optionally, the channel control module also includes an RF test socket 30 and an antenna 40. The second power output by the first channel 20 reaches the RF test socket 30, that is, the RF test socket 30 obtains the plate power, which is usually 22dB, and then output by the antenna 40. The power output by the antenna 40 is the interaction power between the smart terminal product and the base station.

[0083] For further explanation, refer to the attached Fig. 9 As shown, the controller shown in the second embodiment can implement the channel control method in the first embodiment, which specifically includes the following steps: S201: using the transmitter 21 to transmit a first power to control the first channel to start; S202: Amplify the first power by using the radio frequency amplifier 22; S203: Filtering the first power using a bandpass filter in the duplexer; S204: using a directional coupler to couple the filtered first power to generate a second power and coupling energy; S204: Determine whether the current coupling energy meets the first preset condition, if so, command the transmitter to stop or switch to the first channel, otherwise proceed to step S205; S205: Determine whether the current second power meets the second preset condition, if so, instruct the transmitter to compensate the power, otherwise output the second power and end the process.
