[0031] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0032] As mentioned in the background technology, when the communication device is in a low-power state or the communication device is in a low-power state when the super endurance function is enabled, since the power supply voltage is far lower than the normal working voltage of the power amplifier, if the DC / DC converter cannot boost the power supply voltage in time to provide the normal working voltage for the power amplifier, the power amplifier will be underpowered and the output power will be low, resulting in poor communication quality or even inability to communicate, and there will be radiated spurious emission (RSE) compliance issues for the entire machine. Specifically, the inventors have found through testing that when the power supply voltage is normally 4V, the power supply voltage provided by the DC / DC converter to the power amplifier is 3.97V. At this time, the output power of the power amplifier is 32.2dBm, which meets the target power required by the communication. When the power supply voltage is too low and only 3V, the power supply voltage provided by the DC / DC converter to the power amplifier is 3.1V. At this time, the output power of the power amplifier is 28.8dBm, which is 3dBm lower than the output power during normal operation, and does not meet the target power required by the communication. In this regard, the present application provides a voltage regulation method, a voltage regulation device, a communication device and a computer storage medium, which can provide a suitable operating voltage for a power amplifier through a DC / DC converter when the power supply voltage is low, so that the power amplifier can work normally and ensure the communication quality.

[0033] The voltage regulation method provided in the embodiment of the present application can be applied to a communication device with a wireless communication function. The communication device can be a handheld device, a vehicle-mounted device, a customer premises equipment (Customer Premise Equipment, CPE), a wearable device, a computing device or other processing device connected to a wireless modem, as well as various forms of user equipment (User Equipment, UE) (for example, a mobile phone), a mobile station (Mobile Station, MS), etc.

[0034] Figure 1 A schematic diagram of the structure of a communication device is provided. Figure 1 As shown, the communication device includes a power supply 10, a power amplifier 20, a DC / DC converter 30 and a processing circuit 40. Among them, the power supply 10 is used to provide a power supply voltage (VPH PWR). The DC / DC converter 30 is connected to the power supply 10, and the DC / DC converter 30 is used to convert the power supply voltage and output the supply voltage (VCC). The DC / DC converter 30 is a device that converts the electrical energy of one voltage value into the electrical energy of another voltage value in a DC circuit. In an embodiment of the present application, the DC / DC converter 30 is a device that converts the power supply voltage into the supply voltage. Exemplarily, the DC / DC converter 30 can be a DC / DC boost (Boost) device or a DC / DC boost-buck device.

[0035] The power amplifier 20 is connected to the DC / DC converter 30, and the power amplifier 20 is used to support power amplification processing of the radio frequency signal under the action of the power supply voltage. The processing circuit 40 is connected to the power amplifier 20 and the DC / DC converter 30 respectively, and the processing circuit 40 is configured to obtain the communication standard for the communication device to communicate with the base station, and when the power supply voltage is lower than the preset voltage threshold, the DC / DC converter is controlled to perform a voltage boost processing according to the communication standard, so that the adjusted power supply voltage meets the working voltage of the power amplifier 20, thereby ensuring the communication quality.

[0036] Exemplarily, the processing circuit includes at least a radio frequency transceiver. The radio frequency transceiver is connected to the power amplifier 20 and the DC / DC converter 30 respectively. The radio frequency transceiver is used to obtain the communication standard for the communication device to communicate with the base station. When the power supply voltage is lower than the preset voltage threshold, the DC / DC converter 30 is controlled to perform a voltage boost process according to the communication standard so that the adjusted power supply voltage meets the working voltage of the power amplifier 20.

[0037] Optionally, the communication device may further include at least one antenna (such as ANT1 to ANT4), a switch 50 and a low noise amplifier (Low Noise Amplify, LNA) 60. The antenna is used to transmit and receive radio frequency signals. The first end of the switch 50 is connected to the antenna, and the multiple second ends of the switch 50 are respectively connected to the power amplifier 20 and the low noise amplifier 60. The switch 50 is used to select the transmission path between the power amplifier 20 and the antenna, and to select the reception path between the low noise amplifier 60 and the antenna.

[0038] The above-mentioned communication device obtains the communication standard of the communication between the communication device and the base station through the processing circuit 40, and controls the DC / DC converter 30 to boost the power supply voltage according to the communication standard when the power supply voltage provided by the power supply 10 is less than the preset voltage threshold, so that the power supply voltage output by the DC / DC converter 30 after the boost processing meets the working voltage of the power amplifier 20. In this way, by judging the size of the power supply voltage and the preset voltage threshold, the real-time monitoring of the power supply voltage is realized, and when it is detected that the power supply voltage is small, that is, the power supply voltage cannot support the normal operation of the power amplifier 20, such as the communication device is in a low power state or the communication device supporting the super endurance function is in a low power state, the DC / DC converter 30 can be used in time. The power supply voltage is boosted to provide sufficient supply voltage for the power amplifier 20, thereby ensuring the output power of the power amplifier 20, that is, ensuring that the power amplifier 20 supports power amplification processing of radio frequency signals under the current communication standard to meet communication needs, without the need for additional boosting devices, further improving the super endurance performance of the communication equipment, saving costs, and in the boosting process, the supply voltage output after the boosting processing of the DC / DC converter 30 can be adaptively adjusted from the dimension of the communication standard, so that the power amplifier 20 outputs different powers under different supply voltages to support power amplification processing of radio frequency signals under different communication standards, thereby meeting communication needs under different communication standards and improving the reliability of the communication equipment.

[0039] Figure 2 A flow chart of a voltage regulation method is provided. Figure 2 As shown, the voltage regulation method is applied to Figure 1 Taking the communication device shown in the figure as an example, the voltage regulation method includes the following steps S202 and S204.

[0040] S202: Acquire a communication standard used by the communication device to communicate with the base station.

[0041] During the application process, the communication device can receive the RF signal from the base station through the antenna (such as ANT1), switch on the receiving path between the antenna ANT1 and the low noise amplifier, and transmit the RF signal to the processing circuit after low noise amplification by the low noise amplifier, so that the processing circuit can determine the communication standard for the communication device to communicate with the base station based on the RF signal. Among them, the communication standard refers to the network type for wireless communication between the communication device and the base station. The communication standard may include GSM (Global System for Mobile Communications) communication standard, satellite communication standard, LTE (Long Term Evolution) communication standard, NR (New Radio) communication standard and other communication standards generated by subsequent evolution, which are not limited here.

[0042] S204: When the power supply voltage is lower than a preset voltage threshold, control the DC / DC converter to perform a voltage boost process according to the communication standard, so that the adjusted power supply voltage meets the working voltage of the power amplifier.

[0043] The preset voltage threshold is a pre-set voltage value, which serves as a reference value for determining the size of the power supply voltage. It can be set accordingly according to the working requirements of the power amplifier. It can be measured experimentally and is not limited here. If the power supply voltage is lower than the preset voltage threshold, it indicates that the power supply voltage provided by the power supply is much lower than the working voltage of the power amplifier. In this case, the processing circuit can control the DC / DC converter to perform a voltage boost according to the communication standard, so that the adjusted power supply voltage can meet the working voltage of the power amplifier. Among them, the working voltage of the power amplifier can be understood as the voltage that needs to be provided to the power amplifier when the output power of the power amplifier meets a certain value.

[0044] The voltage regulation method obtains the communication standard of the communication between the communication device and the base station, and controls the DC / DC converter to boost the power supply voltage according to the communication standard when the power supply voltage is less than the preset voltage threshold, so that the power supply voltage output by the DC / DC converter after the boost processing meets the working voltage of the power amplifier. In this way, by judging the size of the power supply voltage and the preset voltage threshold, the power supply voltage is monitored in real time, and when it is detected that the power supply voltage is small, that is, the power supply voltage cannot support the normal operation of the power amplifier, such as when the communication device is in a low power state or when the communication device supporting the super endurance function is in a low power state, the power supply can be timely adjusted through the DC / DC converter. The source voltage is boosted to provide sufficient supply voltage for the power amplifier, thereby ensuring the output power of the power amplifier, that is, ensuring that the power amplifier supports power amplification processing of RF signals under the current communication standard to meet communication needs, without the need for additional boosting devices, thereby improving the endurance performance of communication equipment and saving costs. In the boosting process, the supply voltage output after the DC / DC converter boosting processing can be adaptively adjusted from the dimension of the communication standard, so that the power amplifier outputs different powers under different supply voltages to support power amplification processing of RF signals under different communication standards, thereby meeting communication needs under different communication standards and improving the reliability of communication equipment.

[0045] In one embodiment, the communication standard between the communication device and the base station includes one of the GSM communication standard, the satellite communication standard, the LTE communication standard and the NR communication standard. Figure 3 As shown, the above step S204: controlling the DC / DC converter to perform a voltage boost process according to the communication standard may include the following steps S302 and S304.

[0046] S302: When the communication standard is the first communication standard, the DC / DC converter is controlled to perform a first voltage boosting process, wherein the first communication standard includes the GSM communication standard and the satellite communication standard. That is, when the communication standard is the GSM communication standard or the satellite communication standard, the DC / DC converter is controlled to perform a first voltage boosting process so that the power supply voltage output by the DC / DC converter after the voltage boosting process meets the working voltage of the power amplifier.

[0047] S304: When the communication standard is the second communication standard, control the DC / DC converter to perform a second boost process, wherein the second communication standard includes the LTE communication standard and the NR communication standard. That is, when the communication standard is the LTE communication standard or the NR communication standard, control the DC / DC converter to perform a second boost process so that the power supply voltage output by the DC / DC converter after the boost process meets the operating voltage of the power amplifier.

[0048] Among them, the voltage increment corresponding to the first boosting process is greater than the voltage increment corresponding to the second boosting process. In the embodiment of the present application, the power supply voltage is recorded as VPH PWR, or simply VPH, and the supply voltage is recorded as VCC. The voltage increment ΔV corresponding to the boosting process is VPH-VCC, then the voltage increment ΔV1 corresponding to the first boosting process is greater than the voltage increment ΔV2 corresponding to the second boosting process, that is, ΔV1>ΔV2.

[0049] Exemplarily, in order to meet the communication requirements, in the first communication standard (GSM communication standard or satellite communication standard), the operating voltage of the power amplifier is 5V, that is, the DC / DC converter needs to provide a power supply voltage of 5V for the power amplifier; in the second communication standard (LTE communication standard or NR communication standard), the operating voltage of the power amplifier is 4V, that is, the DC / DC converter needs to provide a power supply voltage of 4V for the power amplifier. If the power supply voltage is 3.1V, in the first communication standard, the DC / DC converter boosts the power supply voltage of 3.1V to 5V, and the corresponding voltage increment ΔV1 is 1.9V; in the second communication standard, the DC / DC converter boosts the power supply voltage of 3.1V to 4V, and the corresponding voltage increment ΔV2 is 0.9V.

[0050] The above-mentioned voltage regulation method, when the communication standard is the GSM communication standard or the satellite communication standard, controls the DC / DC converter to perform a large-scale boost processing on the power supply voltage, so that the adjusted power supply voltage meets the working voltage of the power amplifier under the GSM communication standard or the satellite communication standard, and when the communication standard is the LTE communication standard or the NR communication standard, controls the DC / DC converter to perform a small-scale boost processing on the power supply voltage, so that the adjusted power supply voltage meets the working voltage of the power amplifier under the LTE communication standard or the NR communication standard. In this way, by controlling the voltage increment, that is, the boost amplitude, of the power supply voltage boosted by the DC / DC converter, the output power of the power amplifier can meet the communication requirements under the GSM communication standard, the satellite communication standard, the LTE communication standard and the NR communication standard, without the need to additionally provide boost devices for different communication standards, thereby ensuring communication performance, improving the reliability of communication equipment and saving costs.

[0051] In one embodiment, Figure 4 As shown, step S304: obtaining the communication standard for the communication device to communicate with the base station may include the following steps S402 to S406.

[0052] S402: Acquire a modulation mode of a radio frequency signal received by a communication device from a base station.

[0053] Among them, the modulation methods include GMSK (Gaussian Filtered Minimum Shift Keying), 8PSK (8Phase Shift Keying), DEQPSK (differentially-encoded quadrature phase-shift keyed), DEBPSK (differentially-encoded Binary Phase Shift Keying), π / 2BPSK, QPSK (quadrature phase-shift keyed), 16QAM (Quadrature Amplitude Modulation), 64QAM and 256QAM.

[0054] In practical applications, the processing circuit may receive a radio frequency signal from a base station via an antenna, and demodulate the radio frequency signal to obtain a modulation method of the radio frequency signal.

[0055] S404: When the modulation mode is GMSK, 8PSK, DEQPSK or DEBPSK, determine that the communication standard is the first communication standard.

[0056] When the communication standard between the communication device and the base station is determined to be the first communication standard, i.e., the GSM communication standard or the satellite communication standard, the processing circuit can control the DC / DC converter to perform a first boost processing so that the power supply voltage provided to the power amplifier after the DC / DC converter boost processing meets the operating voltage of the power amplifier.

[0057] S406: When the modulation mode is π / 2BPSK, QPSK, 16QAM, 64QAM or 256QAM, determine that the communication standard is the second communication standard.

[0058] When the communication standard of the communication between the communication device and the base station is determined to be the second communication standard, that is, the LTE communication standard or the NR communication standard, the processing circuit can control the DC / DC converter to perform a second boost process so that the power supply voltage provided to the power amplifier after the DC / DC converter boost process meets the operating voltage of the power amplifier. The voltage increment corresponding to the second boost process is less than the voltage increment corresponding to the first boost process.

[0059] The above-mentioned voltage regulation method determines the communication standard between the communication equipment and the base station by obtaining the modulation mode of the radio frequency signal from the base station, so as to control the DC / DC converter to adaptively boost the power supply voltage according to different communication standards, so that when the communication equipment is in the GSM communication standard or the satellite communication standard, the DC / DC converter can provide a higher power supply voltage for the power amplifier to meet the power supply requirements of the power amplifier in the GSM communication standard and the satellite communication standard, and when the communication equipment is in the LTE communication standard or the NR communication standard, the DC / DC converter can provide sufficient power supply voltage for the power amplifier to meet the power supply requirements of the power amplifier in these LTE communication standards and the NR communication standards. In this way, the power supply requirements under various different communication standards can be met, the communication quality of the communication equipment is ensured, and the reliability of the communication equipment is improved.

[0060] In one embodiment, Figure 5 As shown, step S204: controlling the DC / DC converter to perform a voltage boost process according to the communication standard may include the following steps S502 to S506.

[0061] S502: Obtain output feedback power of the power amplifier based on the current supply voltage of the DC / DC converter.

[0062] For example, Figure 1 As shown, a feedback receiving loop (FBRX) may be provided between the power amplifier and the processing circuit. In the application process, when the DC / DC converter supplies power to the power amplifier with the current supply voltage, the output feedback power of the power amplifier may be obtained based on FBRX and transmitted to the processing circuit.

[0063] S504: Determine a target operating voltage of the power amplifier according to the output feedback power and the communication standard.

[0064] During the application process, the processing circuit can determine the target operating voltage of the power amplifier to meet the communication requirements under the communication standard based on the output feedback power sent by FBRX and the pre-established mapping relationship table. Among them, the target power voltage can be understood as a voltage value that not only meets the RF communication requirements of the communication equipment, but also meets the power amplification of the RF signal supported by the power amplifier. Among them, the mapping relationship table is used to represent the corresponding relationship between the power supply voltage VCC of the DC / DC converter, the output feedback power of FBRX and the output power of the power amplifier.

[0065] Table 1 provides a mapping relationship table. It can be seen from Table 1 that the output power of the power amplifier and the output feedback power of FBRX are in one-to-one correspondence. Therefore, in the actual boost process, the supply voltage VCC of the DC / DC converter can be dynamically adjusted according to the output feedback power value of FBRX.

[0066] VCC voltage value FBRX(dBm) Power(dBm) 4V 23 23 3.8V 22 22 3.6V 21 21 3.3V 20 20 … … … 0.8V 0 0

[0067] For example, under the GSM communication standard, if the current power supply voltage VCC of the DC / DC converter is 3.3V, the current output feedback power of the power amplifier is determined to be 20dBm based on FBRX, indicating that the output power of the power amplifier at 3.3V is 20dBm, which is lower than the normal output power of 23dBm. Based on Table 1, it can be seen that the power supply voltage value corresponding to the output power of 23dBm is 4V. Therefore, the power supply voltage needs to be further boosted.

[0068] S506: Control the DC / DC converter to perform voltage boost processing according to the target operating voltage.

[0069] The above-mentioned voltage regulation method, during the boost processing, realizes real-time monitoring of the output power of the power amplifier by acquiring the output feedback power of the power amplifier, thereby determining the target operating voltage of the power amplifier according to the output feedback power and the communication standard, and then controlling the DC / DC converter to boost the power supply voltage according to the target operating voltage, so that the power supply voltage provided to the power amplifier after the DC / DC converter boost processing is adjusted to the target operating voltage, thereby meeting both the power supply requirements of the power amplifier and the communication requirements of the communication equipment, and realizing effective and precise regulation of the power supply voltage. In this way, it can effectively avoid the power consumption caused by the voltage increment corresponding to the boost processing being too large to exceed the target operating voltage in the scenario where the power supply voltage is too low, thereby reducing the power consumption of the communication equipment and helping to improve the endurance performance of the communication equipment.

[0070] In one embodiment, when the communication standard is the GSM communication standard or the satellite communication standard, step S506: controlling the DC / DC converter to perform a boost process according to the target working voltage may include: controlling the DC / DC converter to perform a boost process once.

[0071] Among them, the voltage increment corresponding to a boost process is the difference between the target operating voltage and the current supply voltage. Taking the above step S504 as an example, the current supply voltage of the DC / DC converter is 3.3V, and the target operating voltage of the power amplifier is 4V, then the voltage increment of a boost process ΔV = 0.7V. Based on this, a boost process is performed by the DC / DC converter, so that the supply voltage after a voltage adjustment can meet the power supply demand of the power amplifier, reduce the fluctuation of the power amplifier caused by the low power supply voltage, and improve the reliability of the communication equipment.

[0072] In one embodiment, when the communication standard is the LTE communication standard or the NR communication standard, step S506: controlling the DC / DC converter to perform a boost process according to the target operating voltage may include: controlling the DC / DC converter to perform at least one boost process according to a preset voltage step value to boost the voltage to the target operating voltage.

[0073] The voltage step value is preset and can be set according to actual application requirements. For example, the voltage step value can be 0.1V, 0.5V, 1V, and other suitable values. The number of times the DC / DC converter performs the boost process according to the preset voltage step value can be set according to the current supply voltage, the target operating voltage, or the actual application scenario, and is not limited here.

[0074] Taking the above step S504 as an example, the current supply voltage of the DC / DC converter is 3.3V, and the target operating voltage of the power amplifier is 4V. If the voltage step value is 0.5V, the supply voltage after the DC / DC converter performs a boost process is 3.8V. The difference between the supply voltage and the target supply voltage is 0.2V<0.5V, and the DC / DC converter performs a secondary boost process, and the voltage increment of the secondary boost process is 0.2V. In practical applications, the voltage difference between the current supply voltage and the target operating voltage can be monitored according to the output feedback power fed back by FBRX. If the voltage difference is less than or equal to the voltage step value, the DC / DC converter can directly step down and boost to the target operating voltage next time to avoid power consumption caused by excessive supply voltage.

[0075] Exemplarily, when the communication standard is the LTE communication standard or the NR communication standard, the number of boost processing times of the DC / DC converter is less than or equal to 2, that is, the power supply voltage after the DC / DC converter performs two boost processing can reach the target operating voltage of the power amplifier, thereby ensuring the communication performance of the communication equipment and the normal operation and feedback of the DC / DC converter.

[0076] The voltage regulation method performs at least one voltage boost process according to a preset voltage step value through a DC / DC converter, so that the power supply voltage after voltage regulation can meet the power supply requirement of the power amplifier, thereby improving the reliability of the communication equipment.

[0077] In one embodiment, Figure 6 As shown, after the step of controlling the DC / DC converter to perform at least one voltage boost process according to a preset voltage step value, the voltage regulation method further includes the following steps S602 and S604.

[0078] S602: Obtain the target supply voltage output by the DC / DC converter after the boost process is performed according to the preset boost times. The preset boost times refer to the number of times the DC / DC converter performs the boost process, and the preset boost times are pre-set and can be set according to the actual application scenarios of the power supply, power amplifier, and communication equipment, and are not limited here. For example, when the communication standard between the communication device and the base station is the LTE communication standard or the NR communication standard, the preset boost times are 2.

[0079] S604: When the target power supply voltage is lower than the target operating voltage, generate an alarm signal.

[0080] If the target power supply voltage is less than the target operating voltage, it means that after the DC / DC converter performs the boost processing according to the preset boost times, the power supply voltage is still less than the target operating voltage, and it is unable to provide sufficient power supply voltage for the power amplifier. In this case, the power amplifier cannot be guaranteed to work normally, the output power of the power amplifier is low, and the communication quality of the communication equipment will be affected by the low power supply voltage. Therefore, the processing circuit generates an alarm signal to warn of the low power supply voltage, further improving the reliability of the communication equipment. In practical applications, the processing circuit can also control the DC / DC converter to stop the boost processing to reduce the power consumption caused by the DC / DC converter continuing to perform ineffective boosting.

[0081] In one embodiment, Figure 7 As shown in FIG. 1 , a flow chart of another voltage regulation method is provided. The voltage regulation method is applied to Figure 1 Taking the communication device shown in the figure as an example, the voltage regulation method includes the following steps S702 to S710.

[0083] S704: Determine a communication standard for communication between the communication device and the base station according to the modulation mode of the radio frequency signal.

[0084] S706: Determine whether the power supply voltage is less than a preset voltage threshold. If not, execute the following step S708; if so, execute the following steps S710 to S714.

[0085] S708: The DC / DC converter provides a power supply voltage for the power amplifier.

[0086] S710: When the modulation mode is the LTE communication standard or the NR communication standard, control the DC / DC converter to perform a boost process so that the adjusted supply voltage meets the operating voltage of the power amplifier.

[0087] S712: When the modulation mode is the GSM communication standard or the satellite communication standard, control the DC / DC converter to perform at least one voltage boost process according to a preset voltage step value.

[0088] S714: Determine whether the supply voltage after each boost process of the DC / DC converter is less than the target operating voltage. If yes, execute step S712 again; if no, execute step S708.

[0089] S716: Obtain the supply voltage after the DC / DC converter performs two voltage boost processes, and generate an alarm signal when the supply voltage is lower than the target operating voltage.

[0090] The above voltage regulation method enables the DCDC converter to perform boost processing by detecting the power supply voltage, thereby providing a guarantee for the RF communication performance when the power supply voltage is low.

[0091] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.

Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0092] Based on the same inventive concept, the embodiment of the present application also provides a voltage regulating device for implementing the voltage regulating method involved above.

The converter promptly boosts the power supply voltage to provide sufficient power supply voltage for the power amplifier, thereby ensuring the output power of the power amplifier, that is, ensuring that the power amplifier supports power amplification processing of RF signals under the current communication standard to meet communication needs, without the need for additional boosting devices, further improving the super endurance performance of communication equipment, saving costs, and in the boosting process, the power supply voltage output after the DC / DC converter boost processing can be adaptively adjusted from the dimension of the communication standard, so that the power amplifier outputs different powers under different power supply voltages to support power amplification processing of RF signals under different communication standards, thereby meeting communication needs under different communication standards and improving the reliability of communication equipment.
