[0025] During the process of a user using a communication device (such as a mobile phone, etc.) for a call, capacitive crosstalk that affects the call quality is likely to occur. The audible noise generated by the vibration of the internal structure of the capacitor of the RF PA is one of the sources of capacitive crosstalk. In order to suppress the capacitive crosstalk of the RF PA to ensure the user's call experience, in the prior art, the supply voltage of the RF PA is usually continuously maintained at a relatively large fixed value, resulting in a relatively large power consumption of the RF PA.

[0026] In practical applications, the receiving stage (i.e., the Rx stage) and the transmitting stage (i.e., the Tx stage) are periodic working modes of the RF PA in a communication device (such as a mobile phone, etc.). The receiving stage and the transmitting stage alternate, and the periods of the receiving stage and the transmitting stage are preset.

[0027] The capacitive crosstalk of the RF PA is usually related to the supply voltage difference of the RF PA. The larger the supply voltage difference, the more serious the capacitive crosstalk. In order to suppress the capacitive crosstalk of the RF PA, the supply voltage difference of the RF PA is usually kept at a relatively small fixed value, for example, 0.1V. In this solution, although the RF PA does not need to amplify the signal during the receiving stage, the supply voltage of the RF PA still remains at a relatively high value (this value is close to the supply voltage during the transmitting stage), resulting in a relatively large power consumption of the RF PA. Since the RF PA is one of the main sources of the overall power consumption of the communication device, it further leads to a relatively large overall power consumption of the communication device.

[0028] In view of this, an embodiment of the present application provides a method for determining the supply voltage of a radio frequency power amplifier. In the solution of the embodiment of the present application, the current environment is determined, and the current environment is selected from an alternative set. The alternative set includes a first environment and a second environment, and the noise of the first environment is less than the noise of the second environment; at least based on the current environment, the supply voltage of the radio frequency power amplifier in the receiving stage is determined; wherein, the supply voltage difference in the first environment is less than the supply voltage difference in the second environment, and the supply voltage difference refers to the difference between the supply voltage of the radio frequency power amplifier in the transmitting stage and the supply voltage in the receiving stage.

[0029] In the above solution, the supply voltage of the RF PA during the receiving stage is related to the environment. The greater the environmental noise, the greater the supply voltage difference. By adopting such a solution, it is possible to use the environmental noise to mask the capacitor caw caused by the increase in the supply voltage difference, thereby reducing the supply voltage of the RF PA during the receiving stage without affecting the user's call experience, which is beneficial to reducing the power consumption of the RF PA.

[0030] It should be noted that in the solution of the embodiment of the present application, the supply voltage difference refers to the difference between the supply voltage of the RF PA during the transmitting stage and the supply voltage during the receiving stage. More specifically, for each receiving stage, the supply voltage difference refers to the absolute value of the difference between the supply voltage of this receiving stage and the supply voltage of the nearest previous transmitting stage before this receiving stage.

[0031] It should also be noted that the method provided by the embodiment of the present application can be applied to a communication device including a radio frequency power amplifier. Specifically, the method provided by the embodiment of the present application can be executed by a communication device, components in the communication device (such as a processor, a chip module, a chip, etc.), and the present application does not make any restrictions. Among them, the communication device can be various devices with communication functions. For example, a mobile phone, a wearable device, a tablet computer, a computer, etc. For the convenience of description, this application mainly takes the communication device as the execution subject to elaborate on the embodiments provided by the present application.

[0032] To make the above objects, features, and beneficial effects of the embodiments of the present application more obvious and understandable, the following will describe the specific embodiments of the present application in detail with reference to the accompanying drawings.

[0033] Refer to Figure 1 , Figure 1 is a schematic circuit structure diagram of a communication device in an embodiment of the present application. Among them, Figure 1 The arrows in

[0034] As Figure 1 shown, the communication device may include: a signal transceiver 11, an RF PA 12, and an antenna 13. Among them, the signal transceiver 11 has a signal receiving end and a signal sending end. The signal receiving end of the signal transceiver 11 is electrically connected to the antenna 13, and the signal sending end of the signal transceiver 11 is electrically connected to the antenna 13 via the RF PA 12. Specifically, the signal sending end of the signal transceiver 11 is connected to the signal input end of the RF PA 12, and the signal output end of the RF PA 12 is electrically connected to the antenna 13.

[0035] During the transmission phase, RF PA12 receives a radio frequency signal from the signal transmission end of the signal transceiver 11, amplifies the radio frequency signal, and then sends the signal to the antenna 13 to transmit the signal outward. During the reception phase, the communication device receives a radio frequency signal from the outside through the antenna 13. The antenna 13 directly sends the received radio frequency signal to the signal reception end of the signal transceiver 13, and RFPA12 does not need to amplify the signal.

[0036] Furthermore, the communication device further includes: a power management module 14, and the power management module 14 can be used to supply power to RFPA12. Specifically, the output end of the power management module 14 is electrically connected to the power input end of RF PA12.

[0037] In the solution of the embodiment of the present application, the supply voltage of RF PA12 during the reception phase can be determined according to the environment where the communication device is located. Among them, the greater the noise in the environment, the greater the difference between the supply voltage of RF PA12 during the reception phase and the supply voltage of the previous transmission phase.

[0038] The determination method of "the supply voltage of RF PA12 during the reception phase" can refer to the relevant descriptions below about Figure 2 and Figure 3 .

[0039] It should be noted that the embodiment of the present application does not limit the determination method of the supply voltage of RF PA12 during the transmission phase.

[0040] In an exemplary example, the supply voltage of RF PA12 during the transmission phase can be determined by using the Average Power Tracking (APT) technology.

[0041] Specifically, the supply voltage of RF PA12 during the transmission phase can be determined according to the current required output power of RF PA12. More specifically, the supply voltage of RF PA12 during the transmission phase can be determined based on the APT voltage configuration information. The APT voltage configuration information can include the mapping relationship between the supply voltage during the transmission phase and the target output power of RF PA12. Thus, in practical applications, the supply voltage during the transmission phase can be determined from the APT voltage configuration information according to the current target output power of RF PA12.

[0042] Refer to Figure 2 , Figure 2 is a schematic flowchart of a method for determining the supply voltage of a radio frequency power amplifier in an embodiment of the present application. In specific implementation, the communication device can execute Figure 2The method shown to determine the supply voltage of the RF PA in the receiving phase. Exemplarily, the time interval can be the sum of the periods of the transmitting phase and the receiving phase, but is not limited thereto. Figure 2 The method shown may include the following steps:

[0043] Step S21: Determine the current environment, where the current environment is selected from an alternative set including a first environment and a second environment, and the noise of the first environment is less than the noise of the second environment;

[0044] Step S22: Determine the supply voltage of the radio frequency power amplifier in the receiving phase based at least on the current environment, where the supply voltage difference in the first environment is less than the supply voltage difference in the second environment, and the supply voltage difference refers to the difference between the supply voltage of the radio frequency power amplifier in the transmitting phase and the supply voltage in the receiving phase.

[0045] In a specific implementation of step S21, determine the environment where the communication device is currently located. In other words, determine the environment where the user is currently located.

[0046] Among them, the current environment can be determined by selection from an alternative set, and the alternative set can include multiple candidate environments. Among them, the noises of different candidate environments are different.

[0047] Exemplarily, the alternative set includes a first environment and a second environment, and the noise of the first environment is less than the noise of the second environment.

[0048] In a possible implementation manner, the current environment can be manually set by the user. Specifically, the alternative set can be displayed on the interaction interface, and the user can select the current environment from the alternative set. Exemplarily, the user can select the current environment from the alternative set by means of voice, graphic controls, gestures, etc.

[0049] In another possible implementation manner, considering that the user usually adjusts the volume of the reminder tone when the environment changes, the current environment can be determined according to the volume of the reminder tone set by the user. Among them, the louder the volume of the reminder tone, the greater the noise of the current environment. Among them, the reminder tone can be the message reminder tone of various application programs, or can be the incoming call reminder tone, etc. The embodiments of the present application do not limit the type of the reminder tone. Determining the current environment by the volume of the reminder tone does not require the user to manually set the current environment additionally, nor does it require a noise estimation algorithm to estimate the noise, and can effectively and simply determine the current environment.

[0050] Exemplarily, it can be pre-configured with environment configuration information, which may include the volume range of the prompt tone corresponding to the first environment and the volume range of the prompt tone corresponding to the second environment. Thus, based on the volume of the prompt tone set by the current user and the environment configuration information, it can be determined whether the current environment is the first environment or the second environment.

[0051] Also exemplarily, considering that the user may forget to adjust the prompt tone volume when the environment changes for various reasons. Therefore, when determining the current environment, if the user has updated the prompt tone volume within a preset duration, the current environment can be determined based on the updated prompt tone volume; if the user has not updated the prompt tone volume within the preset duration, the current environment can be determined by using the method of noise estimation.

[0052] In another possible implementation, the current environment can be determined by noise estimation.

[0053] Refer to Figure 3 , Figure 3 is Figure 2 a schematic flowchart of a specific implementation manner of step S21 in Figure 3 As shown, step S21 may include steps S211 to S213.

[0054] Step S211, collect voice signals during the user's call;

[0055] Step S212, perform noise estimation based on the voice signals to obtain the current environmental noise;

[0056] Step S213, determine the current environment based on the current environmental noise and the current environmental noise matching information.

[0057] In the specific implementation of step S211, the original voice signals collected by the microphone can be obtained. Further, after the original voice signals collected by the microphone are subjected to analog-to-digital conversion, voice signals for noise estimation can be obtained. Among them, the voice signals for noise estimation include user voice signals and environmental noise signals. Further, the voice signals for noise estimation can be stored in the memory.

[0058] In the specific implementation of step S212, voice activity detection (VAD) can be performed on the voice signals first to extract user voice signals and noise signals from the voice signals.

[0059] Specifically, in VAD detection, a speech signal can be sequentially divided into multiple speech frames at a step size (such as 20 ms), features are extracted from each speech frame, such as short-time energy features or zero-crossing rate features, and then the feature values are compared with a set threshold. If the feature value is greater than or equal to the threshold, the signal of this speech frame is determined as the user speech signal; if the feature value is less than the threshold, the signal of this speech frame is determined as the noise signal.

[0060] Further, for the speech frames determined to be noise signals, information in the high-frequency region is extracted. Then, the minimum value tracking detection algorithm is used to estimate the noise based on the information in the high-frequency region, and a noise estimation result is obtained.

[0061] Further, based on the user speech signal and the noise estimation result, the current ambient noise is determined.

[0062] It should be noted that the above specific description of step S212 is only an exemplary method for determining the current ambient noise, and the embodiments of the present application do not limit the specific method of noise estimation, which can be various schemes capable of determining the ambient noise.

[0063] In the specific implementation of step S213, ambient noise matching information is read. The ambient noise matching information can include multiple candidate environments and the noise range corresponding to each candidate environment. Further, according to the noise range where the current ambient noise is located, the current environment is determined from the multiple candidate environments.

[0064] Specifically, the ambient noise matching information can include the noise range corresponding to the first environment and the noise range corresponding to the second environment. Thus, it can be determined whether the current environment is the first environment or the second environment.

[0065] Continue to refer to Figure 2 In step S23, at least according to the current environment, the supply voltage of the RF PA in the receiving stage is determined.

[0066] In a possible implementation manner, the supply voltage of the RF PA in the receiving stage in the first environment and the supply voltage of the RF PA in the receiving stage in the second environment are both determined based on the supply voltage in the transmitting stage, but the supply voltage difference in the first environment is less than the supply voltage difference in the second environment.

[0067] For example, the supply voltage in the transmitting stage is V Tx , if the current environment is the first environment, the supply voltage in the receiving stage is V Tx —ΔV1, if the current environment is the second environment, the supply voltage in the receiving stage is V Tx —ΔV2, where ΔV1 > 0, ΔV2 > 0, and ΔV2 > ΔV1.

[0068] It should be noted that determining the supply voltage in the receiving stage based on the supply voltage in the transmitting stage means determining the supply voltage in the receiving stage based on the supply voltage in the most recent transmitting stage. Specifically, a trigger signal can be set in the transmitting stage, and this trigger signal is used to set the supply voltage in the most recent receiving stage after the transmitting stage. When the operating mode of the RF PA switches from the transmitting stage to the receiving stage, the trigger signal is called to set the supply voltage in the receiving stage.

[0069] In another possible implementation, the supply voltage in the receiving stage of the RF PA in the first environment and the supply voltage in the receiving stage in the second environment are both determined based on the maximum value of the optional range of the supply voltage, and the supply voltage in the receiving stage of the RF PA in the first environment is greater than the supply voltage in the receiving stage in the second environment.

[0070] For example, the maximum value of the optional range of the supply voltage is V max , if the current environment is the first environment, the supply voltage in the receiving stage is V max / N, if the current environment is the second environment, the supply voltage in the receiving stage is V max / M, where both M and N are positive integers, and M > N.

[0071] In yet another possible implementation, the supply voltage in the receiving stage of the RF PA in the first environment and the supply voltage in the receiving stage in the second environment are both pre-configured fixed values, and the supply voltage in the receiving stage of the RF PA in the first environment is greater than the supply voltage in the receiving stage in the second environment.

[0072] For example, the supply voltage in the receiving stage of the RF PA in the first environment is V1, and the supply voltage in the receiving stage of the RF PA in the second environment is V2, where V1 > V2.

[0073] In still another possible implementation, the supply voltage in the receiving stage of the RF PA in the first environment is determined based on the supply voltage in the transmitting stage, and the supply voltage in the receiving stage of the RF PA in the second environment depends on the maximum value of the optional range of the supply voltage.

[0074] For example, the supply voltage in the receiving stage of the RF PA in the first environment is V Tx —ΔV, and the supply voltage in the receiving stage of the RF PA in the second environment is V max / M, where ΔV < (V Tx —V max / M).

[0075] In yet another possible implementation, the supply voltage of the RF PA during the receiving phase in the first environment is determined based on the supply voltage during the transmitting phase, and the supply voltage of the RF PA during the receiving phase in the second environment is a fixed value.

[0076] For example, the supply voltage of the RF PA during the receiving phase in the first environment is V Tx —ΔV, and the supply voltage of the RF PA during the receiving phase in the second environment is V2, where ΔV < (V Tx —V2).

[0077] In yet another possible implementation, the supply voltage of the RF PA during the receiving phase in the first environment depends on the maximum value of the optional range of the supply voltage, and the supply voltage of the RF PA during the receiving phase in the second environment is a fixed value.

[0078] For example, the supply voltage of the RF PA during the receiving phase in the first environment is V max / N, and the supply voltage of the RF PA during the receiving phase in the second environment is V2, where (V Tx —V max / N) < (V Tx —V2).

[0079] In a specific example, the alternative set may further include a third environment, where the noise in the third environment is greater than the noise in the second environment, and the supply voltage difference of the RF PA in the second environment is less than the supply voltage difference in the third environment. Among them, the supply voltage of the RF PA during the receiving phase in the first environment is determined based on the supply voltage during the transmitting phase, the supply voltage of the RF PA during the receiving phase in the second environment depends on the maximum value of the optional range of the supply voltage, and the supply voltage of the RF PA during the receiving phase in the third environment is a fixed value.

[0080] For example, the supply voltage of the RF PA during the receiving phase in the first environment is the result obtained by subtracting 0.1V from the supply voltage during the transmitting phase, the supply voltage of the RF PA during the receiving phase in the second environment depends on half of the maximum value of the optional range of the supply voltage, and the supply voltage of the RF PA during the receiving phase in the third environment is 0.5V.

[0081] As described above, in the solution of the embodiments of the present application, the supply voltage of the RF PA during the receiving phase is related to the environment. The greater the environmental noise, the greater the supply voltage difference. By adopting such a solution, it is possible to use the environmental noise to mask the capacitance crosstalk caused by the increase in the supply voltage difference, so as to reduce the supply voltage of the RF RA during the receiving phase without affecting the user's call experience, which is beneficial to reducing the power consumption of the RF RA.
