[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0027] Please refer to Figure 1 , which shows a schematic diagram of a system architecture provided by an exemplary embodiment of the present application. The system architecture may include: a terminal 10 and a network device 20.

[0028] The number of terminals 10 is usually multiple, and one or more terminals 10 may be distributed in each cell managed by a network device 20. The terminal 10 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), etc. For the convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as terminals.

[0029] The network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal 10. The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with network device functions may be different. For example, in the LTE system, it is called eNodeB or eNB; in the 5G NR system, it is called gNodeB or gNB. With the evolution of communication technology, the name "network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal 10 are collectively referred to as network devices.

[0030] In the related art, when power calibration is performed on a terminal, power calibration is usually performed mainly based on one of the multiple modulation modes supported by the terminal to obtain a power calibration result. After the power calibration result is configured to the terminal, the terminal will set the power supply voltage of the power amplifier in the signal transmission circuit and transmit the signal based on the power calibration result regardless of the modulation mode used in the subsequent terminal.

[0031] The uplink throughput of the terminal is related to the called MCS (Modulation Coding Scheme) table, and the larger the MCS value, the higher the corresponding modulation method, and the corresponding throughput is also greater. In weak signal scenarios, due to severe spatial path attenuation, the called MCS value is low, affecting the throughput. In order to improve the throughput in weak signal scenarios, it is necessary to increase the power of high-order modulation methods to obtain better signal quality.

[0032] However, since a unified power calibration result is used under different modulation modes, when the power of a high-order modulation mode needs to be increased, the voltage of the power amplifier under all modulation modes needs to be increased, which will inevitably lead to an increase in power consumption of the low-order modulation mode and affect the terminal's battery life.

[0033] In order to ensure the terminal endurance while improving the uplink throughput in weak signal scenarios, in an embodiment of the present application, the terminal is configured with power calibration results corresponding to different modulation modes, for example, different power calibration results can be configured for high-order modulation modes and low-order modulation modes. When the signal is subsequently transmitted, the terminal calls the corresponding power calibration result to configure the power supply voltage of the power amplifier based on the modulation mode indicated by the network side. Since different modulation modes correspond to different power calibration results, the power calibration result corresponding to the high-order modulation mode can be optimized to improve the signal transmission power of the high-order modulation mode in the weak signal scenario (the power supply voltage of the power amplifier needs to be increased), and the availability of the high-order modulation mode in the weak signal scenario is improved, thereby improving the uplink throughput in the weak signal scenario. At the same time, since there is no need to adjust the power calibration result corresponding to the low-order modulation mode, the power consumption under the low-order modulation mode will not be increased, and the endurance of the terminal is guaranteed.

[0034] See also Figure 2 , Figure 2 is a flowchart of a configuration method of a power amplifier provided by an exemplary embodiment of the present application. Figure 1 Taking the terminal shown as an example, the method may include the following steps.

[0035] Step 201: Receive a scheduling instruction sent by the network side, where the scheduling instruction is used to indicate a target modulation method used by the signal.

[0036] The network side refers to network equipment.

[0037] In some embodiments, the network device determines a target modulation mode that can be used based on the channel quality of the signal between the network device and the terminal, and sends a scheduling instruction to the terminal based on the target modulation mode. There is at least one target modulation mode.

[0038] In a possible implementation, the network device searches the MCS table for a corresponding MCS value (or MCS index) based on the target modulation mode, and adds the MCS value to the scheduling instruction. Correspondingly, after receiving the scheduling instruction, the terminal determines the target modulation mode from the MCS table based on the MCS value carried in the scheduling instruction.

[0039] Step 202, determining a target power calibration result corresponding to a target modulation mode, wherein different modulation modes correspond to respective power calibration results, and the power calibration result is used to indicate a corresponding relationship between a signal output power and a supply voltage of a power amplifier.

[0040] Different from the related art, in which only one set of power calibration results applicable to all modulation modes is configured in the terminal, in the embodiment of the present application, the terminal is configured with at least two sets of power calibration results, wherein different power calibration results are applicable to different modulation modes.

[0041] In some embodiments, different modulation modes correspond to different power calibration results, or some modulation modes correspond to the same power calibration results.

[0042] In the embodiment of the present application, the power calibration result is obtained by calibration based on the power calibration parameters, and different power calibration results are obtained by calibration based on different power calibration parameters.

[0043] In a possible implementation manner, the terminal determines a target power calibration result applicable to the target modulation mode from at least two sets of power calibration results based on the target modulation mode.

[0044] Step 203: configuring the power supply voltage of the power amplifier based on the target power calibration result and the target signal output power.

[0045] Further, the terminal determines a target supply voltage corresponding to the target output power based on the corresponding relationship indicated by the target power calibration result, and supplies power to the power amplifier based on the target supply voltage.

[0046] To summarize, in an embodiment of the present application, by setting power calibration results corresponding to different modulation modes, and subsequently receiving a scheduling instruction issued by the network side, based on the target modulation mode indicated by the scheduling instruction, the target power calibration result corresponding to the target modulation mode is called to configure the supply voltage of the power amplifier, thereby implementing different voltage setting strategies under different modulation modes. This can avoid the problem of using the same voltage setting strategy for different modulation modes. When the power of a high-order modulation mode needs to be increased, the voltage of all modulation modes needs to be adjusted, resulting in excessive power consumption of low-order modulation modes.

[0047] Please refer to Figure 3 , which shows a flow chart of a configuration method of a power amplifier provided by another exemplary embodiment of the present application. This embodiment uses this method for Figure 1 Taking the terminal shown as an example, the method may include the following steps.

[0048] Step 301: Receive a scheduling instruction sent by the network side, where the scheduling instruction is used to indicate a target modulation mode and a reference output power adopted by the signal.

[0049] In addition to indicating the target modulation mode, the scheduling instruction sent by the network side is also used to indicate the reference output power of the terminal when transmitting the signal. The terminal then determines the target signal output power based on the reference output power. For example, the reference output power is 23dBm.

[0050] Step 302: determine a target modulation set to which a target modulation mode belongs from at least two modulation sets, wherein the at least two modulation sets are divided according to modulation orders.

[0051] Since the performance of modulation modes with similar modulation orders are similar, in one possible implementation, developers pre-divide different modulation modes according to their modulation orders to obtain at least two modulation sets, and perform terminal power calibration for each modulation set to obtain power calibration results corresponding to each modulation set, and then deploy at least two sets of power calibration results corresponding to at least two modulation sets in the terminal.

[0052] Optionally, the number of modulation modes included in different modulation sets may be the same or different.

[0053] In some embodiments, the modulation modes are sorted according to the modulation order, and n adjacent modulation modes are divided into the same modulation set. The embodiment of the present application does not further limit the specific division method of the modulation set.

[0054] For each modulation set, a modulation mode in the modulation set is selected, and power calibration parameters are configured and calibrated in the scenario corresponding to the modulation mode, and the power calibration result is determined as the power calibration result corresponding to the modulation set.

[0055] In a possible implementation manner, the at least two modulation sets include a first modulation set and a second modulation set, the first modulation set includes QPSK and 16QAM, and the second modulation set includes 64QAM and 256QAM.

[0056] Optionally, the first power calibration result corresponding to the first modulation set is obtained by calibrating a first power calibration parameter, and the first power calibration parameter is measured based on a maximum ACLR requirement in a QPSK scenario.

[0057] The second power calibration result corresponding to the second modulation set is obtained by calibrating the second power calibration parameter, and the second power calibration parameter is measured based on the highest ACLR (Adjacent Channel Leakage Ratio) requirement (such as above -33dBc) in the 256QAM scenario.

[0058] The first power calibration parameter and the second power calibration parameter are used to characterize the corresponding relationship between the signal output power and the power supply voltage in an experimental environment.

[0059] In some embodiments, the first power calibration parameter and the second power calibration parameter are both measured under a signal waveform (Full RB waveform) with the highest ACLR requirement.

[0060] Regarding the power calibration process, such as Figure 4 As shown, the DC-DC converter 41 (DCDC) fixes the VCC (voltage) and ICQ (current) of the power amplifier 42 (PA) based on the power calibration parameters, traverses the analog gain control word of the RF chip 43 and records the measured power, thereby using the measured power to correct the power in the power calibration parameters to obtain a power calibration result.

[0061] Correspondingly, after determining the target modulation mode, the terminal first determines the target modulation set to which the target modulation mode belongs.

[0062] It should be noted that the number of the above-mentioned modulation sets and the modulation modes included are only for schematic illustration. In actual application, a larger number of modulation sets can be divided according to other standards, and the modulation sets can include other modulation modes besides the above-mentioned modulation modes. This embodiment does not constitute a limitation on this.

[0063] Step 303: Determine a target power calibration result corresponding to the target modulation mode based on the correspondence between the modulation set and the power calibration result, wherein different modulation sets correspond to different power calibration results.

[0064] Furthermore, the terminal determines a power calibration result corresponding to the target modulation set from at least two sets of power calibration results, and the power calibration result is the target power calibration result corresponding to the target modulation mode.

[0065] In an illustrative example, when the target modulation mode indicated by the scheduling instruction is 256QAM, the terminal obtains the second power calibration result corresponding to the second modulation set.

[0066] Step 304: Determine the MPR (Maximum output Power Reduction) parameter corresponding to the target modulation mode.

[0067] Since the peak-to-average ratio of the waveform of high-order modulation is greater than that of the waveform of low-order modulation, the performance indicators of high-order modulation at maximum output power are poor. Therefore, the 3GPP standard introduces MPR for different modulation modes. When determining the target signal output power based on the reference output power indicated by the network side, the terminal needs to determine the corresponding MPR parameters based on the target modulation mode.

[0068] In a possible implementation manner, the terminal stores a correspondence relationship between different modulation modes and MPR parameters, and the terminal obtains the MPR parameters by querying from the correspondence relationship based on the target modulation parameters.

[0069] In some embodiments, when the target modulation mode is a high-order modulation mode, the MPR parameters corresponding to the target modulation mode are optimized based on the target power calibration result, wherein the optimized MPR parameters are smaller than the MPR parameters before optimization.

[0070] In an illustrative example, when the performance of high-order modulation in a weak signal scenario needs to be improved, the MPR parameter corresponding to the high-order modulation can be reduced, thereby improving the signal output power of the high-order modulation in the weak signal scenario. Since high-order modulation and low-order modulation correspond to different power calibration results, increasing the power supply voltage of the power amplifier in a weak signal scenario to increase the signal output power does not affect the power supply voltage of the power amplifier during low-order modulation.

[0071] Step 305: Determine the target signal output power based on the reference output power and the MPR parameter.

[0072] Further, the terminal performs power backoff processing on the reference output power based on the MPR parameter to obtain the target signal output power, wherein the target signal output power = reference output power - MPR parameter.

[0073] In an illustrative example, when the reference output power is 23 dBm and the MPR parameter is 6.5 dB, the terminal determines that the target signal output power is 16.5 dBm.

[0074] Step 306: determine the target supply voltage corresponding to the target signal output power from the target power calibration result.

[0075] The terminal determines the target supply voltage corresponding to the target signal output power from the corresponding relationship between the signal output power and the supply voltage indicated by the target power calibration result.

[0076] Step 307 : configuring the power amplifier based on the target supply voltage.

[0077] In a possible implementation, the terminal controls the DCDC to power a power amplifier in the signal transmission circuit based on the target power supply voltage.

[0078] In this embodiment, multiple modulation sets are obtained according to the modulation order of the modulation method, and a power calibration result is configured for each modulation set. When the terminal subsequently transmits a signal, the power calibration result of the modulation set to which it belongs can be selected based on the modulation method indicated by the network side to determine the actual output power of the power amplifier, and then the supply voltage of the power amplifier is configured, thereby ensuring the signal quality of high-order modulation in weak signal scenarios while avoiding the problem of excessive low-order modulation power.

[0079] In another possible implementation, in order to achieve a more fine-grained configuration, different power calibration results may be set for different modulation modes. Accordingly, the terminal determines the target power calibration result corresponding to the target modulation mode based on the correspondence between the modulation mode and the power calibration result.

[0080] In a possible implementation, four sets of power calibration results corresponding to QPSK, 16QAM, 64QAM and 256QAM are provided in the terminal, and each set of power calibration results is calibrated under corresponding power calibration parameters. Among them, different power calibration parameters are measured based on the highest ACLR requirement in different modulation scenarios, and this embodiment will not be repeated here.

[0081] In addition to the modulation mode, different signal waveforms will also affect the power calibration result. Therefore, in order to further improve the configuration accuracy of the power supply voltage, in a possible implementation, the terminal can jointly determine the power calibration result based on the modulation mode and the signal waveform.

[0082] Please refer to Figure 5 , which shows a flow chart of a configuration method of a power amplifier provided by another exemplary embodiment of the present application. This embodiment uses this method for Figure 1 Taking the terminal shown as an example, the method may include the following steps.

[0083] Step 501, receiving a scheduling instruction sent from the network side, where the scheduling instruction is used to indicate a target modulation mode, a target signal waveform, and a reference output power adopted by the signal.

[0084] In addition to indicating the target modulation mode, the scheduling instruction sent by the network side is also used to indicate the reference output power of the terminal when transmitting the signal and the target signal waveform used during modulation.

[0085] Among them, the signal waveform may include CP-OFDM (Cyclic Prefix Orthogonal Frequency Division Multiplexing) waveform and DFT-OFDM (Discrete Fourier Transform Orthogonal Frequency Division Multiplexing) waveform, etc. The embodiment of the present application does not limit the type of signal waveform.

[0086] Step 502: determine a target modulation set to which a target modulation mode belongs from at least two modulation sets, wherein the at least two modulation sets are divided according to modulation orders.

[0087] Since modulation modes with similar modulation orders have similar performances, in a possible implementation, developers pre-divide different modulation modes according to their modulation orders to obtain at least two modulation sets.

[0088] Optionally, the number of modulation modes included in different modulation sets may be the same or different.

[0089] In some embodiments, the modulation modes are sorted according to the modulation order, and n adjacent modulation modes are divided into the same modulation set. The embodiment of the present application does not further limit the specific division method of the modulation set.

[0090] In a possible implementation manner, the at least two modulation sets include a first modulation set and a second modulation set, the first modulation set includes QPSK and 16QAM, and the second modulation set includes 64QAM and 256QAM.

[0091] Step 503: Determine a target power calibration result corresponding to a target modulation mode and a target signal waveform based on the corresponding relationship between the signal waveform, the modulation set and the power calibration result.

[0092] Since both the signal waveform and the modulation mode affect the power calibration result, in a possible implementation manner, the signal waveform and the modulation set are combined, and a power parameter calibration is performed for each combination to obtain a power calibration result.

[0093] In some embodiments, when the terminal supports n signal waveforms and is divided into m modulation sets, the developer needs to configure n×m sets of power calibration results.

[0094] Optionally, for each modulation set, a modulation mode in the modulation set is selected, and a signal waveform is selected from multiple signal waveforms, power calibration parameters are configured and calibrated in the scenario corresponding to the modulation mode + signal waveform, and the power calibration result is determined as the power calibration result corresponding to the modulation set + signal waveform.

[0095] In a possible implementation manner, four sets of power calibration results are configured in the terminal, where:

[0096] The first power calibration result corresponding to the CP-OFDM waveform and the first modulation set is obtained by calibrating a first power calibration parameter, where the first power calibration parameter is measured based on a maximum ACLR requirement in a CP-QPSK scenario;

[0097] The second power calibration result corresponding to the DFT-OFDM waveform and the first modulation set is obtained by calibrating a second power calibration parameter, where the second power calibration parameter is measured based on the highest ACLR requirement in the DFT-QPSK scenario;

[0098] A third power calibration result corresponding to the CP-OFDM waveform and the second modulation set is obtained by calibrating a third power calibration parameter, where the third power calibration parameter is measured based on a maximum ACLR requirement in a CP-256QAM scenario;

[0099] A fourth power calibration result corresponding to the DFT-OFDM waveform and the second modulation set is obtained by calibrating a fourth power calibration parameter, where the fourth power calibration parameter is measured based on a maximum ACLR requirement in a DFT-QAM scenario;

[0100] Among them, the first power calibration parameter, the second power calibration parameter, the third power calibration parameter and the fourth power calibration parameter are used to characterize the corresponding relationship between the signal output power and the power supply voltage in the experimental environment.

[0101] In some embodiments, the power calibration parameters are measured under a signal waveform (Full RB waveform) with the highest ACLR requirement.

[0102] Correspondingly, the terminal determines a target power calibration result corresponding to the target modulation mode and the target signal waveform based on the correspondence between the signal waveform, the modulation set and the power calibration result.

[0103] Schematically, the correspondence between the signal waveform, the modulation set and the power calibration result is shown in Table 1. When the terminal determines that the target signal waveform is CP-OFDM and the target modulation mode is 16QAM, the terminal determines to use the power calibration result B.

[0106] Table 1

[0107] Step 504: Determine the MPR parameters corresponding to the target modulation mode.

[0108] Since the peak-to-average ratio of the waveform of high-order modulation is greater than that of the waveform of low-order modulation, the performance indicators of high-order modulation at maximum output power are poor. Therefore, the 3GPP standard introduces MPR for different modulation modes. When determining the target signal output power based on the reference output power indicated by the network side, the terminal needs to determine the corresponding MPR parameters based on the target modulation mode.

[0109] In a possible implementation manner, the terminal stores a correspondence relationship between different modulation modes and MPR parameters, and the terminal obtains the MPR parameters by querying from the correspondence relationship based on the target modulation parameters.

[0110] In some embodiments, when the target modulation mode is a high-order modulation mode, the MPR parameters corresponding to the target modulation mode are optimized based on the target power calibration result, wherein the optimized MPR parameters are smaller than the MPR parameters before optimization.

[0111] In an illustrative example, when the performance of high-order modulation in a weak signal scenario needs to be improved, the MPR parameter corresponding to the high-order modulation can be reduced, thereby improving the signal output power of the high-order modulation in the weak signal scenario. Since high-order modulation and low-order modulation correspond to different power calibration results, increasing the power supply voltage of the power amplifier in a weak signal scenario to increase the signal output power does not affect the power supply voltage of the power amplifier during low-order modulation.

[0112] Step 505: Determine the target signal output power based on the reference output power and the MPR parameter.

[0113] Further, the terminal performs power backoff processing on the reference output power based on the MPR parameter to obtain the target signal output power, wherein the target signal output power = reference output power - MPR parameter.

[0114] In an illustrative example, when the reference output power is 23 dBm and the MPR parameter is 6.5 dB, the terminal determines that the target signal output power is 16.5 dBm.

[0115] Step 506: determine the target supply voltage corresponding to the target signal output power from the target power calibration result.

[0116] The terminal determines the target supply voltage corresponding to the target signal output power from the corresponding relationship between the signal output power and the supply voltage indicated by the target power calibration result.

[0117] Step 507 , configuring the power amplifier based on the target supply voltage.

[0118] In a possible implementation, the terminal controls the DCDC to power a power amplifier in the signal transmission circuit based on the target power supply voltage.

[0119] In this embodiment, multiple modulation sets are obtained according to the modulation order of the modulation method, and a power calibration result is configured for the combination of "modulation set + signal waveform"; when the terminal subsequently transmits a signal, the corresponding power calibration result can be selected based on the modulation method and signal waveform indicated by the network side to determine the actual output power of the power amplifier, and then the power supply voltage of the power amplifier is configured, thereby realizing targeted voltage configuration under different signal waveforms and different modulation method scenarios, and optimizing the high-order modulation power without affecting the power consumption of the low-order modulation.

[0120] In another possible implementation, in order to achieve a more fine-grained configuration, different power calibration results can be set for different modulation modes and signal waveforms. Accordingly, the terminal determines the target power calibration result corresponding to the target modulation mode and target signal waveform based on the correspondence between the modulation mode, signal waveform and the power calibration result.

[0121] In a possible implementation, the terminal is provided with eight sets of power calibration results corresponding to (CP-OFDM+QPSK), (DFT-OFDM+QPSK), (CP-OFDM+16QAM), (DFT-OFDM+16QAM), (CP-OFDM+64QAM), (DFT-OFDM+64QAM), (CP-OFDM+256QAM), and (DFT-OFDM+256QAM), and each set of power calibration results is calibrated under corresponding power calibration parameters. Among them, different power calibration parameters are measured based on the highest ACLR requirement in different modulation scenarios, and this embodiment will not be repeated here.
