The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
The present application relates to a radio frequency front end, and for facilitating understanding of embodiments of the present application, a detailed description of the radio frequency front end related to the present application is first provided.
The radio frequency front end may be an important part of the terminal device wireless communication module. For example, the terminal device may be a mobile phone, a tablet computer, or the like.
The radio frequency front end is described below with reference to fig. 1-2.
Fig. 1 is a schematic structural diagram of a wireless communication module of a terminal device according to an embodiment of the present application. Referring to fig. 1, the wireless communication module may include an antenna, a radio frequency front end, a radio frequency chip, a baseband, and the like.
The antenna, radio frequency front end, radio frequency chip, and baseband may together form the transmit path/uplink and receive path/downlink of the terminal device.
Fig. 2 is a schematic structural diagram of a radio frequency front end according to an embodiment of the present application. Referring to fig. 2, the rf front end may include a low noise amplifier, a power amplifier, a filter, a duplexer, a switch, and the like.
In the transmitting path of the terminal device, the signal input to the terminal device may sequentially pass through the baseband, the radio frequency chip, the power amplifier, the filter, the duplexer, and the switch, and finally be transmitted through the antenna. For example, the signal input to the terminal device may be a voice signal, a video signal, or the like.
In the receiving path of the terminal device, the electromagnetic wave signal received by the antenna may sequentially pass through the antenna, the switch, the duplexer, the filter, the low noise amplifier, and the radio frequency chip, and finally output through the baseband.
In the wireless communication module, when the terminal equipment transmits signals, the baseband can convert the signals input into the terminal equipment into intermediate frequency signals, and the radio frequency chip can modulate the intermediate frequency signals into radio frequency signals; or when the terminal equipment receives the signal, the radio frequency chip can modulate the radio frequency signal into an intermediate frequency signal, and the baseband can convert and output the intermediate frequency signal.

The filter can retain radio frequency signals within a specific frequency band and filter out signals outside the specific frequency band.
The diplexer can isolate signals transmitted by the terminal device from received signals so as to ensure that the transmitted and received signals can work normally under the condition of sharing one antenna.
The switch can realize the switching between the transmission and the reception of the radio frequency signals and the switching between different frequency bands.
The radio frequency front end may include a plurality of filtering devices. For example, the filter device may be a filter, a duplexer, a power amplifier, or the like. The amplitude-frequency response of the filter device in the signal channel is poor, so that the accuracy of the data transmission of the radio frequency front end is poor.
In the related art, to compensate for the degradation of the amplitude-frequency response caused by the filter device, a feedback loop may be provided at the rf front end. The feedback loop can determine the amplitude-frequency response compensation coefficient of the terminal equipment, and calibrate the radio frequency signal passing through the filter device according to the amplitude-frequency response compensation coefficient so as to compensate the amplitude-frequency response deterioration brought by the filter device. However, a first-stage filter is usually further disposed after the feedback loop of the rf front-end, so that the amplitude-frequency response compensation coefficient determined by the feedback loop cannot accurately compensate for the deterioration of the amplitude-frequency response, which results in poor accuracy of data transmission of the rf front-end.
In view of this, the present application provides a compensation coefficient determining method, which can control a terminal device to sequentially transmit a plurality of test signals with specified power at a plurality of specified frequency points, can control a power measurer to measure the power of the plurality of test signals transmitted by the terminal device, and can determine an amplitude-frequency response compensation coefficient of the terminal device according to the power of the plurality of test signals measured by the power measurer. By the method, amplitude-frequency response deterioration caused by all filter devices of the radio frequency front end of the terminal equipment can be compensated, the accuracy of amplitude-frequency response compensation coefficients of the terminal equipment is improved, and the accuracy of data transmission of the radio frequency front end of the terminal equipment is higher.

It should be noted that, the power of the signal transmitted when the terminal device is operating normally may be obtained from the configuration information of the terminal device.
By way of example, assuming that the terminal device transmits a voice signal at a power of 20W, 20W may be determined as the target test power.
In another possible implementation, the target test power may be determined experimentally. The specific implementation of the test may be referred to S402, which is not described herein.

The plurality of frequency points may be frequency points in a frequency band for which amplitude-frequency response compensation is required.
It should be noted that, the frequency band to be subjected to amplitude-frequency response compensation may be a frequency band in which any terminal device may transmit a signal, which is not limited in this embodiment of the present application.
In this embodiment, the plurality of frequency points may be frequency points uniformly distributed in a frequency band requiring amplitude-frequency response compensation at a fixed frequency interval.
For example, assuming a fixed frequency interval of 1Mhz, the frequency band in which the terminal device needs to perform amplitude-frequency response compensation is 909Mhz-915Mhz. The plurality of frequency points may be a plurality of frequency points starting from 909Mhz and ending at 915Mhz with 1Mhz as an interval.

For any one of the test signals, the target measurement power may be the power of the test signal measured by the power measurer.
In this embodiment, a plurality of target measurement powers of a plurality of test signals may be obtained from the power measurer.
For example, assuming that the terminal device sequentially transmits test signals with a target test power of 20W at 7 frequency points, the power measurer may sequentially measure the 7 test signal powers. Assume that 7 target measurement powers sequentially measured by the power measurer are respectively: 19.94W, 19.85W, 19.88W, 19.79W, 19.84W, 19.98W, and 19.84W. The 7 target measured powers described above can be obtained from the power measurer.
S304, determining an amplitude-frequency response compensation coefficient of the terminal equipment according to the plurality of target measurement powers.
In this embodiment, the amplitude-frequency response compensation coefficient of the terminal device may be determined as follows: determining an amplitude value corresponding to each target measurement power to obtain a plurality of amplitude values; normalizing the plurality of amplitude values to obtain a plurality of normalized amplitude values; and determining a plurality of amplitude-frequency response compensation coefficients of the terminal equipment at a plurality of frequency points according to the plurality of normalized amplitude values.
For any one target measured power, the method for determining the amplitude-frequency response compensation coefficient of the frequency point corresponding to the target measured power is consistent according to the target measured power. Next, a method of determining the amplitude-frequency response compensation coefficient of the frequency point corresponding to any one of the target measured powers will be described by taking the target measured powers as an example.
In this embodiment, the target measured power may be converted into the amplitude value according to the conversion relationship between the target measured power and the amplitude value. And normalizing the converted amplitude value to obtain an amplitude-frequency response compensation coefficient of the frequency point corresponding to the target measurement power.
It should be noted that, the conversion relation between the target measurement power and the amplitude value, and the amplitude value normalization processing method may refer to related technologies, and the embodiments of the present application are not limited thereto.
The compensation coefficient determining method provided by the embodiment can determine the target test power of the terminal equipment to be tested, can control the terminal equipment to sequentially transmit a plurality of test signals at a plurality of frequency points according to the target test power, can acquire a plurality of target measurement powers of the power measurer for testing the plurality of test signals, and can determine the amplitude-frequency response compensation coefficient of the terminal equipment according to the plurality of target measurement powers. By the method, amplitude-frequency response deterioration caused by all filter devices of the radio frequency front end of the terminal equipment can be compensated, the accuracy of amplitude-frequency response compensation coefficients of the terminal equipment is improved, and the accuracy of data transmission of the radio frequency front end of the terminal equipment is higher.
On the basis of the above embodiments, the target test power may also be determined experimentally. Next, a test method for determining the target test power will be described with reference to fig. 4.
Fig. 4 is a flowchart of another compensation coefficient determining method according to an embodiment of the present application. As shown in fig. 4, the method of the present embodiment includes:

For example, assume that the preset frequency point is 910Mhz, the frequency band where the preset frequency point is located is 909Mhz-915Mhz, and the preset frequency difference is 1Mhz. The first frequency band may be a 909Mhz-915Mhz band and the plurality of frequency points may be 909Mhz, 910Mhz, 911Mhz, 912Mhz, 913Mhz, 914Mhz, and 915Mhz, respectively.
S404, the control terminal equipment sequentially transmits a plurality of test signals at a plurality of frequency points according to the target test power.
In this embodiment, the control terminal device sequentially transmits a plurality of test signals at a plurality of frequency points according to the target test power, which at least includes the following two modes:
the number of the mode one and the plurality of frequency points is M, and M is an integer greater than 1; transmitting a j-th transmitting instruction to the terminal equipment, wherein the j-th transmitting instruction comprises a j-th frequency point and target test power; j is 1, 2, … … and M in sequence; the j-th transmitting instruction is used for indicating the terminal equipment to transmit a test signal according to the target test power at the j-th frequency point.
In this manner, a plurality of transmission instructions may be transmitted to the terminal device, and the number of transmission instructions may be the same as the number of the plurality of frequency points. Each transmit instruction may include a target test power, and a frequency bin.
For example, assuming a target test power of 20W, the number of the plurality of frequency points is 7, and the plurality of frequency points are 909Mhz, 910Mhz, 911Mhz, 912Mhz, 913Mhz, 914Mhz, and 915Mhz in this order. Then 7 transmit instructions may be sent to the terminal device in turn. The 1 st transmit instruction may include a frequency point 909Mhz, and a target test power 20W; the 2 nd transmit instruction may include a frequency point 910Mhz, and a target test power 20W; the 3 rd transmit instruction may include a frequency point 911Mhz, and a target test power 20W; the 4 th transmit instruction may include frequency point 912Mhz, and target test power 20W; the 5 th transmission instruction may include a frequency point 913Mhz, and a target test power 20W; the 6 th transmit instruction may include frequency point 914Mhz, and target test power 20W; the 7 th transmit instruction may include a frequency point 915Mhz, and a target test power 20W.
Correspondingly, the terminal device can receive 7 transmitting instructions and can sequentially transmit corresponding test signals according to the 7 transmitting instructions. For example, a test signal with a power of 20W may be transmitted at frequency point 909Mhz according to the 1 st transmission instruction.
And the second mode is that a transmitting instruction is sent to the terminal equipment, wherein the transmitting instruction comprises a plurality of frequency points and target test power, and the transmitting instruction is used for indicating the terminal equipment to transmit test signals according to the target test power at the plurality of frequency points respectively.
In this manner, 1 transmission instruction may be sent to the terminal device, and the 1 transmission instruction may include a plurality of frequency points and target test power.
For example, assuming a target test power of 20W, the plurality of frequency bins are 909Mhz, 910Mhz, 911Mhz, 912Mhz, 913Mhz, 914Mhz, and 915Mhz in that order. Then 1 transmit instruction may be sent to the terminal device, which may include a plurality of frequency points 909Mhz, 910Mhz, 911Mhz, 912Mhz, 913Mhz, 914Mhz, and 915Mhz; the transmit instruction may also include a target test power 20W.
Correspondingly, the terminal device can receive the transmission instruction, and can transmit a test signal with 20W of power on each frequency point according to the transmission instruction.
