[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] As mentioned in the background section, communication devices use the same set of parameters for power calibration at all output power points of the power amplifier. However, communication scenarios are often diverse. Using the same set of parameters for power calibration in different scenarios not only results in significant power consumption but also fails to effectively improve power to enhance communication performance. Therefore, this application provides a power calibration method, apparatus, communication device, and computer storage medium that can improve the performance of the power amplifier, further optimize its power consumption and power output, and thus enhance communication performance.

[0042] The power calibration method provided in this application can be applied to communication devices with wireless communication capabilities. The communication device includes at least one power amplifier, which can be used to amplify the power of radio frequency signals. The communication device can be a handheld device, an in-vehicle device, a customer pre-installed equipment (CPE), a wearable device, a computing device, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE) (e.g., mobile phones), mobile stations (MS), etc.

[0043] The power calibration method provided in this application is applicable to Average Power Tracking (APT) and Envelope Tracking (ET) technologies, as well as Digital Pre-Distortion (DPD) calibration technologies, and other suitable calibration technologies, without limitation.

[0044] In one embodiment, such as Figure 1 As shown, a power calibration method is provided. Taking the application of this method to a communication device as an example, the method includes the following steps S101 to S104.

[0045] S101: Obtain the configuration information for uplink communication on the communication device.

[0046] Configuration information can be related to uplink (UL) communication of the communication device, where uplink communication can be the process of the communication device sending data to network infrastructure such as base stations, servers, and satellites. For example, configuration information includes, but is not limited to, at least one of the following: waveform, frequency band, modulation method, resource block type, bandwidth, and current output power of the power amplifier of the uplink communication signal. In this embodiment, configuration information can be used to adjust the output power of the power amplifier of the communication device. For example, the communication device can obtain control information sent from the network side, and obtain the uplink communication configuration information by parsing the control information; or, the communication device can directly call the pre-configured configuration information. In applications, the communication device can use appropriate methods to obtain configuration information according to the actual scenario; this is only an illustrative example and does not constitute a limitation.

[0047] S102: Determine the communication mode of the communication device based on the configuration information.

[0048] Communication devices can determine their communication mode based on configuration information. Since the communication requirements of communication devices differ under different communication modes, the communication device can determine the current communication mode based on the configuration information. These communication requirements include linearity / adjacent channel leakage ratio (ACLR), throughput, output power, etc. For example, the communication mode includes at least one of mobile cellular communication mode, satellite communication mode, and wireless network (WiFi) communication mode. For example, the configuration information includes, but is not limited to, at least one of the following: the network identifier for the communication device's uplink communication, the communication mode icon for the communication device, and the frequency band of the communication device's uplink communication signal. Based on this, the communication device can determine the communication mode according to one or more of these configuration information.

[0049] S103: Determine the target compensation dataset of the target power amplifier of the communication device according to the communication mode, wherein the target compensation dataset is different for different communication modes.

[0050] The target compensation dataset is pre-set, and the communication device can pre-set multiple compensation datasets. Since the communication requirements differ for different communication modes, this application embodiment sets different compensation datasets for different communication modes. In application, the communication device can determine the target compensation dataset for the power amplifier from multiple compensation datasets based on the communication mode. The compensation dataset includes multiple compensation data, which are used to compensate the operating parameters of the power amplifier. The compensation parameters include relevant parameters affecting the output power of the power amplifier. For example, the compensation parameters include at least one of compensation power, compensation voltage, and compensation current. The compensation power can be used to compensate the output power of the power amplifier, the compensation voltage can be used to compensate the supply voltage of the power amplifier, and the compensation current can be used to compensate the quiescent current of the power amplifier.

[0051] S104: Adjust the output power of the target power amplifier based on the configuration information and the target compensation dataset.

[0052] In applications, communication devices can determine the current operating parameters and compensation parameters of the power amplifier based on the configuration information, and then compensate the current operating parameters using the compensation parameters to adjust the output power of the power amplifier.

[0053] For example, the compensation parameters include compensation power. The communication device can determine the current output power and compensation power of the power amplifier based on the configuration information, and compensate the current output power by the compensation power, thereby adjusting the output power of the power amplifier using the compensated output power. In other words, the output power of the power amplifier is controlled to be the compensated output power.

[0054] Another example is that the compensation parameters include the compensation voltage. The communication device can determine the current supply voltage and compensation voltage of the power amplifier according to the configuration information, and compensate the current supply voltage by the compensation voltage, thereby adjusting the output power of the power amplifier using the compensated supply voltage. That is, controlling the supply voltage of the power amplifier to be the compensated supply voltage, thereby realizing the adjustment of the output power of the power amplifier.

[0055] Another example is that the compensation parameters include the compensation current. The communication device can determine the current quiescent current and the compensation current of the power amplifier based on the configuration information, and compensate the current quiescent current by the compensation current, thereby adjusting the output power of the power amplifier by the compensated quiescent current.

[0056] The aforementioned power calibration method involves a communication device acquiring uplink communication configuration information. Based on this information, the communication device can determine its communication mode and then determine the target compensation dataset for the power amplifier. The output power of the power amplifier is then adjusted based on the target compensation dataset and the configuration information, achieving effective control of the power amplifier's output power during communication. Since the target compensation dataset differs for different communication modes, the method provided in this application can compensate the current operating parameters of the power amplifier based on the compensation parameters in the target compensation dataset under different communication modes. This optimizes the power amplifier's performance while meeting communication requirements, adapting to various communication modes and enabling differentiated power calibration control under different communication modes. Compared to related technologies that use the same set of parameters for power calibration regardless of the communication mode, this application customizes the target compensation dataset for the power amplifier for multiple different communication modes, optimizing power amplifier performance, reducing power consumption, increasing output power, improving communication performance, and avoiding performance redundancy.

[0057] In one embodiment, the configuration information includes a network identifier for uplink communication of the communication device. The network identifier is used to distinguish and identify different communication modes of the communication device. Specifically, the network identifier includes at least one of a non-terrestrial network (NTN) identifier, a mobile cellular network identifier, and a wireless network identifier.

[0058] Figure 2 A schematic diagram of an NTN network architecture is provided. Combined with... Figure 2 NTN is a general term for all networks involving flying objects, including satellite communication networks, high-altitude platform systems, air-to-ground networks, and unmanned aerial vehicles (UAVs). It is characterized by long distances, high mobility, and wide coverage. In areas where terrestrial network equipment is not widely available, NTN, combined with satellite and UAV platforms, can achieve New Radio (NR) communication and complete network coverage, such as in extreme areas like deserts and oceans, further enhancing coverage. Figure 2 As shown, the NTN network architecture can be simply viewed as satellites in the sky functioning as base stations. The service link between communication equipment and satellites is implemented through NR, and the feedback link between satellites and gateways is implemented through 3GPP or non-3GPP radio interfaces. The gateway is connected to the data network. Figure 3 and Figure 4 Two different NTN network architectures are provided. Figure 3 This provides a schematic diagram of an architecture in an NTN network pass-through mode. For example... Figure 3As shown, the satellite merely forwards the signal without performing any processing. Figure 4 The diagram provided is an architecture diagram of an NTN network regeneration mode, in which the satellite needs to process the data.

[0059] The non-terrestrial network identifier can be used to determine whether the communication device is in satellite communication mode. For example, the non-terrestrial network identifier includes at least one of satellite ID, orbital position, and service area code.

[0060] A mobile cellular network identifier can be used to determine that a communication device is in mobile cellular communication mode. For example, a mobile cellular network identifier includes at least one of MCC (Mobile Country Code), MNC (Mobile Network Code), LAC (Location Area Code), TAC (Tracking Area Code), CI (Cell ID), and ECI (E-UTRAN Cell ID).

[0061] A wireless network identifier can be used to determine whether a communication device is in wireless network communication mode. For example, a wireless network identifier includes at least one of SSID (Service Set Identifier), BSSID (Basic Service Set Identifier), and the frequency channel through which the wireless network is operating.

[0062] Based on the above, step S102, determining the communication mode of the communication device according to the configuration information, may include: the communication device determining its communication mode based on a network identifier. Specifically, the communication device may determine the communication mode as satellite communication mode based on a non-terrestrial network identifier; the communication device may determine the communication mode as mobile cellular communication mode based on a mobile cellular network identifier; or the communication device may determine the communication mode as wireless network communication mode based on a wireless network identifier.

[0063] The target compensation datasets differ for satellite communication mode, mobile cellular communication mode, and wireless network communication mode. In application, communication devices can pre-configure compensation datasets for satellite communication mode, mobile cellular communication mode, and wireless network communication mode. After determining the communication mode based on configuration information, the communication device can then determine the target compensation dataset corresponding to that communication mode from multiple compensation datasets.

[0064] The aforementioned power calibration method determines the communication mode based on the network identifier of the uplink communication, thereby recognizing different communication modes. It then determines the target compensation dataset for the power amplifier based on the communication mode and adjusts the output power of the power amplifier according to the configuration signal and the target compensation dataset. This allows for compensation of the power amplifier's current operating parameters based on the compensation parameters in the target compensation dataset under different communication modes. While meeting communication requirements, it further optimizes the performance of the power amplifier, adapting to various communication modes, including satellite communication, mobile cellular communication, and wireless network communication. This enables differentiated control of power calibration under different communication modes, helping to reduce power consumption, increase the output power of the power amplifier, improve communication performance, and avoid performance redundancy.

[0065] In the context of satellite communication in NTN networks, NTN networks benefit from extensive service coverage and the ability of spacecraft to mitigate the impact of physical attacks and natural disasters. NTN can enhance network performance in unserved areas (remote areas, on aircraft or ships) and underserved areas (e.g., suburbs, rural areas) where terrestrial 5G networks cannot reach. Furthermore, NTN networks can provide service continuity or ensure service availability anywhere for machine-to-machine (M2M) devices, Internet of Things (IoT) devices, or passengers on mobile platforms (e.g., passenger vehicles—airplanes, ships, high-speed trains, buses), particularly critical communications, future rail, maritime, or air communications. It also enables 5G network scalability by providing efficient multicast or broadcast resources for transmitting data to the network edge and even user terminals. Additionally, NTN involves standalone non-terrestrial networks or integrated terrestrial and non-terrestrial networks, which will impact coverage, user bandwidth, system capacity, service reliability or availability, energy consumption, and connection density. NTN in 5G communication systems can be applied to various fields such as transportation, public safety, media and entertainment, e-health, energy, agriculture, finance, and automobiles. In this regard, this application further subdivides the communication modes of communication devices, performing differentiated calibration of the power amplifier's power according to different communication modes to improve the power amplifier's performance, thereby enhancing the communication performance of the communication device. This is applicable to satellite communication modes under the aforementioned NTN networks (such as Tiantong satellite system, Xingwang satellite system, and millimeter-wave system), mobile cellular communication modes under 5G networks, wireless network communication modes under WiFi, and other communication modes that will evolve subsequently, without limitation.

[0066] In one embodiment, such as Figure 5 and Figure 6As shown, the target power amplifier includes a first power amplifier 111 and a second power amplifier 211. The first power amplifier 111 is used to support power amplification of a first radio frequency signal in satellite communication mode and power amplification of a second radio frequency signal in mobile cellular communication mode. The second power amplifier 211 is used to support power amplification of a third radio frequency signal in wireless network communication mode. The first, second, and third radio frequency signals each have different frequency bands. For example, the first radio frequency signal includes at least one of GSM, UMTS, CDMA, 4G LTE, and 5G NR signals. The second radio frequency signal includes at least one of L-band, C-band, Ku-band, Ka-band, and X-band. The third radio frequency signal includes at least one of WiFi 2.4GHz and WiFi 5GHz signals.

[0067] Combination Figure 5 and Figure 6 ,like Figure 7 As shown, step S103, determining the target compensation dataset of the target power amplifier of the communication device according to the communication mode, may include the following steps: determining a first target compensation dataset of the first power amplifier 111 according to the satellite communication mode; or, determining a second target compensation dataset of the first power amplifier 111 according to the mobile cellular communication mode; or, determining a third target compensation dataset of the second power amplifier 211 according to the wireless network communication mode. The first target compensation dataset, the second target compensation dataset, and the third target compensation dataset are all different.

[0068] Understandably, since communication requirements differ under different communication modes—for example, linearity, throughput, and output power—this application sets different compensation datasets for different communication modes and calls different target compensation datasets to compensate the operating parameters of the power amplifier under different communication modes, thereby achieving differentiated power calibration under different communication modes. Furthermore, at the hardware architecture level, a first power amplifier 111 is set for mobile cellular communication mode and satellite communication mode, and a second power amplifier 211 is set for wireless network communication mode. This enables the reuse of the first power amplifier 111 for mobile cellular communication mode and satellite communication mode, reducing device footprint and cost.

The first radio frequency transceiver 112 is connected to the first power amplifier 111, the first low-noise amplifier 113, and the first coupler 115. The first duplexer 114 is connected to the first power amplifier 111, the first low-noise amplifier 113, and the first coupler 115. The first coupler 115 is also connected to the first antenna ANT1. The first radio frequency transceiver 112 supports the transmission and reception of a first radio frequency signal and a second radio frequency signal. The first low-noise amplifier 113 supports low-noise amplification of the first and second radio frequency signals. The first duplexer 114 isolates the signal from the first power amplifier 111 and the signal from the first antenna ANT1. The first coupler 115 transmits the received signal to the first radio frequency transceiver 112 for power calibration. The first power supply 116 is connected to the first power amplifier 111, and the first power supply 116 is used to provide a first power supply voltage to the first power amplifier 111.

[0070] Please continue reading. Figure 6 For example, the communication device may further include a second radio frequency transceiver 212, a second low-noise amplifier 213, a second duplexer 214, a second coupler 215, a second power supply 216, and a second antenna ANT2. The second radio frequency transceiver 212 is connected to the second power amplifier 211, the second low-noise amplifier 213, and the second coupler 215. The second duplexer 214 is connected to the second power amplifier 211, the second low-noise amplifier 213, and the second coupler 215. The second coupler 215 is also connected to the second antenna ANT2. The second radio frequency transceiver 212 supports the transmission and reception of a third radio frequency signal. The second low-noise amplifier 213 supports low-noise amplification of the third radio frequency signal. The second duplexer 214 isolates signals from the second power amplifier 211 and signals from the second antenna ANT2. The second coupler 215 transmits the received signal to the second radio frequency transceiver 212 for power calibration. The second power supply 216 is connected to the second power amplifier 211, and the second power supply 216 is used to provide a second power supply voltage to the second power amplifier 211.

[0071] In one embodiment, the configuration information includes the current output power of the power amplifier and the signal parameters for uplink communication on the communication device. For example, the current output power includes the first output power of the first power amplifier 111 and the second output power of the second power amplifier 211. The signal parameters include some signal parameters that affect the linearity requirements of the uplink communication signal. For example, the signal parameters include at least one of the waveform, frequency band, bandwidth, modulation scheme, and resource block type used to transmit the uplink communication signal. These can be determined according to actual conditions and are not limited in detail here.

[0072] Based on the above, such as Figure 7 As shown, step S104, adjusting the output power of the target power amplifier according to the configuration information and the target compensation dataset, may include the following steps S701 to S703.

[0073] S701: Determine the target compensation parameters of the target power amplifier based on the current output power, signal parameters, and target compensation dataset; wherein, the target compensation dataset includes multiple compensation data, which are used to represent the mapping relationship between the current output power of the target power amplifier, the signal parameters of the uplink communication of the communication device, and the compensation parameters.

[0074] The compensation data can be non-volatile (NV) data, which can be pre-stored in the non-volatile random access memory (NVRAM) of the communication device. During application, compensation parameters can be extracted through experimental testing, and a mapping relationship can be established between the compensation parameters and the output power and signal parameters of the target power amplifier, thereby obtaining the compensation dataset. Furthermore, compensation parameters can be obtained using any one or more methods among table lookup, linear interpolation, and linear fitting, or other suitable methods; no limitation is made here.

[0075] S702: Determine the target supply voltage of the target power amplifier based on the current output power, compensation parameters, and preset reference calibration data; wherein, the reference calibration data is used to represent the mapping relationship between the output power of the target power amplifier and the supply voltage of the target power amplifier.

[0076] Reference calibration data is pre-acquired and stored in the communication equipment. It serves as the raw data used to calibrate the target power amplifier. For uplink communication signals with different signal parameters, the reference calibration data can be used to calibrate the output power of the target power amplifier. Reference calibration data can be understood as universal calibration data, without needing to consider differences in communication modes or the signal parameters of uplink communication signals. The reference calibration data can be presented in the form of functions, curves, tables, etc. Figure 8 A schematic diagram of reference calibration data is shown, where the horizontal axis represents the supply voltage V / v of the target power amplifier, and the vertical axis represents the output power P / dBm of the target power amplifier. The supply voltage refers to the voltage required for the target power amplifier to operate normally; it can also be understood as the voltage provided by the power supply to the target power amplifier.

[0077] S703: Adjusts the output power of the target power amplifier according to the target supply voltage.

[0078] In applications, communication equipment can adjust the supply voltage of the target power amplifier to the target supply voltage, so that the target power amplifier can amplify the uplink communication signal under the action of the target supply voltage, thereby realizing the adjustment of the output power of the target power amplifier.

[0079] The aforementioned power calibration method, because the compensation dataset includes multiple compensation data representing the mapping relationship between the output power, signal parameters, and compensation parameters of the target power amplifier, can obtain the compensation parameters corresponding to the signal parameters and the current output power from the compensation dataset. Therefore, based on the reference calibration data, the target supply voltage of the power amplifier at the current output power can be determined, and the output power of the target power amplifier can be calibrated according to this target supply voltage. Compared to directly calling the same set of parameters to calibrate the output power of the target power amplifier in any communication scenario, this embodiment, under the initial division of communication modes, further refines the different application scenarios of the target power amplifier from multiple dimensions of the uplink communication signal signal parameters. This allows for adaptive compensation of the operating parameters of the target power amplifier using compensation parameters for uplink communication signals with different signal parameters, thereby improving the performance of the power amplifier and helping to reduce power consumption and increase output power.

[0080] In one embodiment, the signal parameters include at least one of the following: frequency band, waveform, modulation scheme, bandwidth, and resource block type of the uplink communication signal of the communication device.

[0081] A frequency band is used to represent the frequency range of uplink communication signals on a communication device. A frequency band includes at least one of the FR1 and FR2 bands. The FR1 band ranges from 450MHz to 6.0GHz and includes Band1, Band2, Band3, Band5, Band7, Band8, Band20, Band28, Band40, Band77, Band78, Band79, n255, and n256. The FR1 band ranges from 6.0GHz to 52.6GHz. Table 1 provides information related to the n255 and n256 bands within FR1 used by satellite communication systems under the NTN network. In applications, other band division methods can be used; for example, the frequency band parameters may include at least one of the following: low frequency band (LB), middle frequency band (MB), high frequency band (HB), ultra-high frequency band (UHB), and millimeter wave band. This is not limited here.

[0083]

[0084] Waveforms are used to represent the waveforms of uplink communication signals on communication equipment. Waveforms include at least one of Discrete Fourier Transform-Spread Orthogonal Frequency-Division Multiplexing (DFT-S-OFDM) waveforms and Cyclic Prefix Orthogonal Frequency-Division Multiplexing (CP-OFDM) waveforms.

[0085] The modulation scheme is used to represent the modulation method of the uplink communication signal on the communication device. The modulation scheme includes at least one of Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), and Quadrature Amplitude Modulation (QAM). Specifically, QAM includes at least one of 16QAM, 64QAM, and 256QAM.

[0086] Bandwidth refers to the channel width of the uplink communication signal on a communication device. For example, bandwidth values ​​range from 5MHz to 100MHz, as shown in Table 2 below. Table 3 shows the channel bandwidth corresponding to the n256 and n255 frequency bands for the NTN satellite communication mode.

[0091] Resource block (RB) types are used to indicate the type of resource block used to transmit uplink communication signals. Examples of resource block types include edge RB, outer RB, and inner RB. Table 4 shows the different modulation schemes and RB types corresponding to DFT-S-OFDM waveforms (DFT) and CP-OFDM waveforms (CP).

[0094]

[0095] The aforementioned power calibration method finely divides the uplink communication scenarios of the communication device from multiple different dimensions of the uplink communication signal, such as frequency band, waveform, modulation method, bandwidth, and resource block type. This allows for the subdivision of different scenarios in which the power amplifier amplifies the uplink communication signal based on these different signal parameters. Furthermore, by using compensation datasets corresponding to different parameters, the method adaptively compensates the output power of the power amplifier operating in different scenarios. Compared to related technologies that use the same set of parameters for power calibration regardless of the modulation method for different signal parameters, such as DFT and CP waveforms, the calibration method provided in this application subdivides the application scenarios of the power amplifier supporting one or more combinations of frequency bands, waveforms, modulation methods, bandwidth, and resource block types of the uplink communication signal. It also performs differentiated power calibration for different communication scenarios, which can improve the performance of the power amplifier and help achieve goals such as reducing power consumption, increasing output power, and increasing throughput.

[0096] In one embodiment, the target compensation dataset includes at least one of a power compensation dataset and a voltage compensation dataset. The power compensation data in the power compensation dataset represents the mapping relationship between the output power of the target power amplifier, the signal parameters of the uplink communication on the communication device, and the compensation power. The voltage compensation data in the voltage compensation dataset represents the mapping relationship between the output power of the target power amplifier, the signal parameters of the uplink communication on the communication device, and the compensation voltage.

[0097] In applications, communication devices can store at least one of power compensation datasets and voltage compensation datasets. During calibration, the communication device can select one of the power compensation datasets or the voltage compensation dataset to adjust the output power of the target power amplifier using either the compensation voltage or the compensation power. Based on the voltage compensation dataset, the supply voltage of the target power amplifier can be adjusted via compensation voltage, thereby adjusting the output power of the target power amplifier. Based on the power compensation dataset, the output power of the target power amplifier can be adjusted via compensation power. In other words, the communication device can calibrate the output power of the target power amplifier from both output power and supply voltage perspectives, achieving the goals of reducing power consumption and increasing output power, thus enhancing the diversity of power calibration methods.

[0098] In one embodiment, the target compensation dataset includes a voltage compensation dataset. Step S701, determining the compensation parameters of the power amplifier based on the current output power, signal parameters, and the target compensation dataset, may include: determining the target compensation voltage of the target power amplifier based on the current output power, signal parameters, and the voltage compensation dataset. Since the voltage compensation data represents the mapping relationship between the output power of the target power amplifier, the signal parameters of the uplink communication signal on the communication device, and the compensation voltage, the communication device can obtain the corresponding compensation voltage from the voltage compensation dataset based on the current output power of the target power amplifier and the signal parameters of the uplink communication signal. In this embodiment, the compensation voltage is denoted as ΔV. ΔV can be a negative or positive value.

[0099] In applications, the target compensation voltage can be obtained using any one or more methods, such as table lookup, linear interpolation, and linear fitting, or other suitable methods, without limitation. For example, assume a first output power PA and a second output power PB, corresponding to a first compensation voltage ΔVA and a second compensation voltage ΔVB, respectively. The target output power is Px, corresponding to a target compensation voltage ΔVx. The compensation coefficient k = (ΔVB - ΔVA) / (PA - PB). Then the target compensation voltage ΔVx is: ΔVx = k * (Px - PA) + ΔVA = (ΔVB - ΔVA) * (Px - PA) / (PA - PB) + ΔVA. Based on this, in the embodiments of this application, the target compensation voltage corresponding to any output power can be quickly determined based on linear interpolation or curve fitting, improving the accuracy and efficiency of determining the target compensation voltage.

[0100] Step S702, determining the target supply voltage of the power amplifier based on the current output power, compensation parameters, and reference calibration data, may include: determining the calibration voltage corresponding to the output power based on the current output power and reference calibration data, and determining the first target supply voltage of the target power amplifier based on the calibration voltage and the target compensation voltage.

[0101] The calibration voltage refers to the supply voltage corresponding to the current output power of the target power amplifier in the reference calibration data. The calibration voltage can be understood as the reference voltage used for calibration before compensation, or, in other words, the voltage used to calibrate the target power amplifier without considering the signal parameters of the uplink communication signal on the communication device. For example, using... Figure 8 Taking the reference calibration data shown as an example, if the output power of the power amplifier is 16.5 dBm, the calibration voltage corresponding to this output power can be obtained as the calibration voltage Vd at point D; if the output power of the power amplifier is 23 dBm, the calibration voltage corresponding to this output power can be obtained as the calibration voltage Va at point A. In this embodiment, the calibration voltage is denoted as V1.

[0102] The first target supply voltage is the voltage obtained by compensating the calibration voltage with a compensation voltage. In this embodiment, the first target supply voltage is denoted as V2. The first target supply voltage is positively correlated with the calibration voltage. For example, the first target supply voltage is the sum of the calibration voltage and the compensation voltage, i.e., V2 = V1 + ΔV. When the compensation voltage ΔV is negative, the first target supply voltage is negatively correlated with the compensation voltage, and the first target supply voltage is less than the calibration voltage, i.e., V2 < V1. Therefore, based on the calibration voltage, the calibration voltage is further reduced to adjust the supply voltage of the target power amplifier to the first target supply voltage, and the power amplifier is powered by the first target supply voltage. When the compensation voltage ΔV is positive, the first target supply voltage is positively correlated with the compensation voltage, and the first target supply voltage is greater than the calibration voltage, i.e., V2 > V1. Therefore, based on the calibration voltage, the calibration voltage is further increased to adjust the supply voltage of the target power amplifier to the first target supply voltage, and the power amplifier is powered by the first target supply voltage.

[0103] The aforementioned power calibration method, since the voltage compensation dataset includes multiple voltage compensation data representing the mapping relationship between the output power of the target power amplifier, signal parameters, and compensation voltage, can obtain the compensation voltage corresponding to the signal parameters and current output power from the voltage compensation dataset. This allows adjustment of the supply voltage of the target power amplifier under the given output power scenario. When the compensation voltage is negative, the calibration voltage is reduced to decrease the supply voltage of the target power amplifier, enabling the target power amplifier to reduce power consumption while meeting radio frequency signal transmission requirements such as linearity. Conversely, when the compensation voltage is positive, the calibration voltage is increased to increase the supply voltage of the power amplifier, enabling the target power amplifier to increase its output power while meeting radio frequency signal transmission requirements such as linearity, thereby improving the throughput of the communication equipment and ultimately enhancing its transmission performance. Compared to directly calling the same set of parameters to calibrate the power amplifier's output power, this application refines the power amplifier's application scenarios from multiple dimensions, including the communication mode of the communication equipment and the signal parameters of the uplink communication signal. This allows for adaptive compensation of the calibration voltage using the compensation voltage for uplink communication signals with different signal parameters under different communication modes, achieving the goals of reducing power consumption and improving transmission performance.

[0104] In one embodiment, the target compensation dataset includes a power compensation dataset. Step S701, determining the compensation parameters of the power amplifier based on the current output power, signal parameters, and the target compensation dataset, may include: determining the target compensation power of the target power amplifier based on the current output power, signal parameters, and the power compensation dataset. The power compensation data represents the mapping relationship between the output power of the target power amplifier, the signal parameters of the uplink communication signal, and the compensation power. Therefore, the corresponding compensation power can be obtained from the power compensation dataset based on the current output power of the target power amplifier and the signal parameters of the uplink communication signal of the communication device. In this embodiment, the compensation power is denoted as ΔP. ​​ΔP can be a negative or positive value.

[0105] In applications, the target compensation power can be obtained using any one or more methods, such as table lookup, linear interpolation, and linear fitting, or other suitable methods, without limitation. For example, assume a first output power PA and a second output power PB, corresponding to a first compensation power ΔPA and a second compensation power ΔPB, respectively. The target output power is Px, corresponding to a target compensation power ΔPx. The compensation coefficient k = (ΔPB - ΔPA) / (PA - PB). Then the target compensation power ΔPx is: ΔPx = k * (Px - PA) + ΔPA = (ΔPB - ΔPA) * (Px - PA) / (PA - PB) + ΔPA. Based on this, in the embodiments of this application, the target compensation power corresponding to any output power can be quickly determined based on linear interpolation or curve fitting, improving the accuracy and efficiency of determining the target compensation voltage.

[0106] Step S702, determining the target supply voltage of the power amplifier based on the current output power, compensation parameters, and reference calibration data, may include: determining the target output power of the target power amplifier based on the current output power and the target compensation power, and determining the second target supply voltage of the target power amplifier based on the target output power and the reference calibration data.

[0107] The target output power is the power obtained by compensating the current output power with compensation power. In this embodiment, the target output power is denoted as P2. The target output power is positively correlated with the current output power. For example, the target output power is the sum of the current output power and the compensation power, i.e., P2 = P1 + ΔP. When the compensation power ΔP is negative, the target output power is negatively correlated with the compensation power, and the target output power is less than the current output power, i.e., P2 < P1. When the compensation power ΔP is positive, the target output power is positively correlated with the compensation power, and the target output power is greater than the current output power, i.e., P2 > P1.

[0108] The second target supply voltage is the target output power determined based on the target output power after compensating the current output power with the compensated power. For example, using... Figure 8 Taking the reference calibration data shown as an example, if the target output power of the target power amplifier is the power at point A, then the supply voltage corresponding to point A can be determined as the second target supply voltage. It can be understood that the voltage corresponding to point C is... Figure 8 The reference calibration data shown provides the calibration value, while the voltage corresponding to point A is the calibration value obtained after compensating and adjusting point C based on point C using the power calibration method provided in this application.

[0109] The aforementioned power calibration method, because the power compensation dataset includes multiple power compensation data points representing the mapping relationship between the output power of the target power amplifier, the signal parameters of the uplink communication signal, and the compensation power, can obtain the compensation power corresponding to the signal parameters and the current output power from the power compensation dataset. This allows adjustment of the supply voltage of the target power amplifier under that output power scenario. When the compensation power is negative, the supply voltage of the target power amplifier is reduced by decreasing the calibration power, enabling the power amplifier to reduce power consumption while meeting RF signal transmission requirements such as linearity. Conversely, when the compensation power is positive, the calibration power is increased. By increasing the supply voltage of the power amplifier, the target power amplifier can increase its output power while meeting the requirements for radio frequency signal transmission, such as linearity requirements, thereby increasing the throughput of the communication equipment and improving its transmission performance. Compared to directly calling the calibration power in the reference calibration data to calibrate the output power of the power amplifier, this application embodiment refines the different application scenarios of the power amplifier from multiple dimensions such as the communication mode of the communication equipment and the signal parameters of the uplink communication signal. For uplink communication signals with different signal parameters in different communication modes, the compensation power is used to adaptively compensate the calibration voltage to reduce power consumption and improve transmission performance.

[0110] In one embodiment, the output power range of the target power amplifier includes multiple power intervals. Each power interval has a different preset output power range. The number of power intervals is greater than two, for example, five, six, eight, or any other arbitrary value. Table 3 shows five power intervals uniformly divided in 5dBm units. In practical applications, the power intervals can also be divided non-uniformly. To facilitate obtaining compensation parameters, each power interval can be labeled using interval identifiers, with each interval having a unique identifier. For example, in Table 5, the five power intervals are labeled with numbers 1 to 5.

[0111] Table 5

[0112] Power range 1 20dBm~max Power range 2 15~20dBm Power range 3 10–15 dBm Power range 4 5~10dBm Power range 5 0~5dBm

[0113] Each power range is configured with multiple sub-compensation datasets. The compensation data in each sub-compensation dataset represents the mapping relationship between the power range, signal parameters, and compensation parameters. The number of sub-compensation datasets configured for each power range is greater than two, for example, three, four, or five. For example, the sub-compensation datasets can be represented in a tabular format, referred to as compensation sub-tables. Different subset identifiers can also be used to label different sub-compensation datasets to obtain the compensation parameters. Sub-compensation datasets can be further divided using the signal parameters of the uplink communication signal. Taking bandwidth as an example, after the sub-compensation datasets are divided firstly by output power, they can be divided secondly by bandwidth. For example, each compensation sub-table represents the mapping relationship between the waveform, modulation method, and resource block type of the uplink communication signal and the compensation parameters under a certain power range and a certain bandwidth. In applications, other methods can also be used to define the form of the compensation datasets and to divide the compensation datasets using other parameter combinations. This is only an example and is not intended to impose further limitations.

[0114] Figure 9 Seven power ranges [0] to [6] are shown, each with eight compensation sub-tables [0] to [7]. Among them, compensation sub-table [0] includes compensation parameters corresponding to the output power within the power range [0], the RF signal being in the LB band, the waveform (DFT-S-OFDM, CP-OFDM), the modulation method (BPSK, QPSK, 16QAM, 64QAM, 256QAM), and the resource block position (edgeRB, Outer RB, and Inner RB). Similarly, unlike compensation sub-table [0], compensation sub-tables [1] to [3] correspond to MB, HB, and UHB, respectively, and compensation sub-tables [4] and [5] correspond to some special frequency bands such as band3 and band28. Compensation sub-tables [4] and [5] are used as backup tables (reverse). In practical applications, taking the power amplifier for power amplification of the RF signal of band1 as an example, first, we find that its output power is in the power range [0]. Then, band1 belongs to the LB frequency band, so the index value idx of the compensation sub-table corresponding to band1 is 1. That is, we find the compensation parameter NV from the compensation sub-table [1] according to the waveform, modulation method and resource block position of the RF signal. Table 6 shows Figure 9 The correspondence between the n256 and n255 frequency bands and the index values ​​of the compensation sub-table in the NTN network satellite communication mode.

[0117] In practical applications, the following can be adopted: Figure 9The compensation data corresponding to multiple typical output power points is stored in the manner shown. The compensation parameters corresponding to other output power points can be obtained by linear interpolation or curve fitting, etc., and are not limited here.

[0118] The power calibration method described above divides the output power of the power amplifier into power ranges and represents the mapping relationship between the power range, the signal parameters of the uplink communication signal, and the compensation parameters by combining the sub-compensation dataset. This allows the compensation parameters to be obtained by indexing the power range and the sub-compensation dataset during the power calibration process, thereby adjusting the power supply voltage of the power amplifier and improving the data processing rate.

[0119] In one embodiment, the power calibration method further includes: performing the aforementioned step S102 when the current communication environment meets preset communication conditions. The preset communication conditions include one of the following: the current communication channel is a PUCCH (Physical Uplink Control Channel); the current communication channel is a PUSCH (Physical Uplink Shared Channel); and the target uplink communication signal is an SRS (Sounding Reference signal). Thus, by considering the current communication environment of the communication device, the target power amplifier is calibrated and compensated under the target environment that meets the preset communication conditions. This avoids useless compensation operations, saves power consumption, and effectively optimizes power consumption and signal linearity processing for scenarios that meet the conditions.

[0120] In one embodiment, such as Figure 10 As shown, the power calibration method may further include steps S1001 to S1003 to obtain a compensation dataset.

[0121] S1001: Obtain the first reference supply voltage of the target power amplifier at the current output power and with the linearity parameter meeting the preset linearity condition.

[0122] Linearity parameters are used to represent the linearity of the target power amplifier. For example, linearity parameters include the Adjacent Channel Leakage Ratio (ACLR). Preset linearity conditions are pre-defined and can be set according to the application scenario of the target power amplifier. For example, a linearity parameter meeting the preset linearity condition can be defined as the linearity parameter being less than a preset linearity threshold. For instance, if the linearity parameter is ACLR and the preset linearity threshold is set to -33dBc, then the power amplifier's ACLR is less than -33dBc, indicating that the power amplifier's linearity parameter meets the preset linearity condition.

[0123] The first reference supply voltage refers to the supply voltage at which the linearity parameter of the target power amplifier meets a preset linearity condition at its output power. For example, the first reference supply voltage can be the minimum supply voltage at which the target power amplifier meets the preset linearity condition at that output power. It can be understood that if the target power amplifier has good linearity at that output power, the supply voltage can be appropriately reduced to decrease the power amplifier's power consumption while ensuring that its linearity parameter meets the preset linearity condition.

[0124] S1002: Obtain compensation parameters based on the current output power, the first reference supply voltage, and the reference calibration data.

[0125] Compensation parameters include compensation voltage or compensation power. Taking compensation voltage as an example, such as... Figure 11 As shown, the solid line represents the reference calibration data, and the dashed line represents the first reference supply voltage of the uplink communication signal RF1 (e.g., RF1 has CP waveform, QPSK, and RB1 position) at various output powers, where the linearity parameter meets the preset linearity condition. For example, when the current output power of the target power amplifier is 24.7dBm, the calibration voltage corresponding to this output power can be obtained from the solid line as the voltage Va at point A. At the same output power, the first reference supply voltage of the uplink communication signal RF1 can be obtained from the dashed line as the voltage Vb at point B. Then the compensation parameter ΔV1 = Vb - Va < 0. When the current output power of the target power amplifier is 16.5dBm, the calibration voltage corresponding to this output power can be obtained from the solid line as the voltage Vc at point C. At the same output power, the first reference supply voltage of the uplink communication signal RF1 can be obtained from the dashed line as the voltage Vd at point D. Then the compensation parameter ΔV2 = Vd - Vc < 0.

[0126] Taking the compensation parameter as the compensation power as an example, such as Figure 12 As shown, the solid line represents the reference calibration data, and the dashed line represents the first reference supply voltage of the uplink communication signal RF1 at various output powers, provided that the linearity parameter meets the preset linearity condition. For example, when the current output power of the target power amplifier is 24.7dBm, according to the solid line, this output power corresponds to point A; according to the dashed line, the first reference supply voltage of the uplink communication signal RF1 at this output power is the voltage Vb at point B; and according to the solid line, the calibration power corresponding to the first reference supply voltage Vb is the power Pc at point C. Therefore, the compensation parameter ΔP1 = Pc - Pa < 0. When the current output power of the target power amplifier is 16.5dBm, according to the solid line, this output power corresponds to point D; according to the dashed line, the first reference supply voltage of the uplink communication signal RF1 at this output power is the voltage Ve at point E; and according to the solid line, the calibration power corresponding to the first reference supply voltage Ve is the power Pf at point F. Therefore, the compensation parameter ΔP2 = Pf - Pd < 0.

[0127] S1003: Obtain the compensation dataset based on the signal parameters, output power, and compensation parameters.

[0128] After obtaining the compensation parameters based on the above steps, a mapping relationship is established between the signal parameters, output power, and compensation parameters to obtain the compensation dataset.

[0129] The aforementioned power calibration method obtains a first reference supply voltage for the power amplifier at its output power, provided that the linearity parameters meet preset linearity conditions. It then obtains compensation parameters based on the output power, the first reference supply voltage, and reference calibration data. Finally, it obtains a compensation dataset based on the signal parameters, output power, and compensation parameters. Thus, based on the reference calibration data, the corresponding compensation parameters are obtained from the compensation dataset according to the signal parameters and output power to compensate the reference calibration data, thereby adjusting the power amplifier's supply voltage and calibrating the power amplifier's output power. This decouples the power amplifier from the MPR (Maximum Power Ratio) while maintaining linearity requirements, achieving the goal of reducing power consumption.

[0130] In one embodiment, such as Figure 13 As shown, the power calibration method may further include the following steps S1301 to S1303.

[0131] S1301: When the signal strength of the uplink communication signal is less than the preset strength threshold, the maximum power of the current output power is reduced as a change amount to increase the current output power.

[0132] If the uplink communication signal strength is less than a preset strength threshold, it indicates that the spatial path attenuation of the uplink communication signal is large, resulting in a low Modulation and Coding Scheme (MCS) value for network calls and poor throughput of the communication device. In this case, this embodiment of the application increases the current output power by using the Maximum Power Reduction (MPR) as a variable to obtain better signal quality and achieve higher throughput performance. The maximum power reduction can be determined based on the current output power.

[0133] S1302: Obtain the second reference supply voltage of the target power amplifier at the increased output power and with linearity parameters meeting the preset linearity conditions.

[0134] The second reference supply voltage refers to the supply voltage at which the linearity parameter of the target power amplifier meets the preset linearity condition under the increased output power. For example, the second reference supply voltage can be the minimum supply voltage at which the linearity parameter of the target power amplifier meets the preset linearity condition under the increased output power. It can be understood that after the output power of the target power amplifier is increased, in order to meet the preset linearity condition, the supply voltage can be appropriately increased to improve signal quality while also achieving the linearity requirement.

[0135] S1303: Obtain compensation parameters based on the current output power, the second reference supply voltage, and the reference calibration data.

[0136] Taking the compensation parameter as the compensation voltage as an example, such as Figure 14 As shown, the curve represents the reference calibration data. For example, when the output power of the target power amplifier after amplifying the uplink communication signal RF2 (e.g., DFT waveform, 256QAM, RB2 position) is 16.5dBm, the curve corresponds to point E, and the MPR is 2dBm. When the output power is increased to 18.5dBm, the curve corresponds to point F. The curve shows that the calibration voltage at the output power of 18.5dBm is the voltage Vg at point G. Point G may not meet the linearity requirements due to high-order modulation, etc. According to the experimental measurement, the second reference supply voltage required to meet the preset linearity conditions is the voltage Vh at point H. Therefore, the compensation voltage ΔV3 = Vh - Vg > 0.

[0137] Taking the compensation parameter as the compensation power as an example, such as Figure 15 As shown, the curve represents the reference calibration data. For example, when the output power of the target power amplifier after amplifying the uplink communication signal RF2 (e.g., DFT waveform, 256QAM, RB2 position) is 16.5dBm, the curve shows that the output power corresponds to point G, the MPR is 2dBm, and the output power is increased to 18.5dBm. The curve shows that the calibration voltage at the output power of 18.5dBm is the voltage Vh at point H. Point H may not meet the linearity requirements due to high-order modulation, etc. According to the experimental measurement, the second reference supply voltage required to meet the preset linearity conditions is the voltage Vm at point M. The curve shows that the calibration power at voltage Vm is the power Pn at point N. Therefore, the compensation power ΔP3 = Pn - Ph > 0.

[0138] S1304: Obtain the compensation dataset based on the signal parameters, the increased output power, and the compensation parameters.

[0139] After obtaining the compensation parameters based on the above steps, a mapping relationship is established between the signal parameters, output power, and compensation parameters to obtain the compensation dataset.

[0140] The aforementioned power calibration method can improve throughput by increasing the output power of the power amplifier while meeting linearity requirements, thereby enhancing the transmission performance of communication equipment. For example, for different modulation signals at the same power, such as DFT-S-OFDM and CP-OFDM signals, to achieve the same linearity (i.e., the same ACLR), since the peak-to-average power ratio (PAPR) of the CP-OFDM signal is larger than that of the DFT-S-OFDM signal, the power calibration method provided in the above embodiment can be used. For DFT-S-OFDM and CP-OFDM signals with the same linearity requirements, the supply voltage of the power amplifier can be increased for the CP-OFDM signal to further improve its linearity, achieving the same output power and the same linearity.

[0141] In one embodiment, a power calibration method is provided. For ease of understanding, as follows: Figure 16 A schematic diagram illustrating the process of power calibration for communication equipment based on a voltage compensation mechanism is provided. For example... Figure 17 A schematic diagram illustrating the process of power calibration in communication equipment based on a power compensation mechanism is provided. Combined with... Figures 1 to 17 The power calibration process is explained for two scenarios: power consumption optimization and power optimization.

[0142] In satellite communication mode, for the uplink communication signal RF3 of the PUSCH channel, which has a DFT waveform, uses 16QAM modulation, and has a resource block type of RB3, the current output power of the first power amplifier 111 is obtained as 24.7dBm. Figure 11 Point A in the diagram. Then, the signal strength of the uplink communication signal RF3 is obtained. If the signal strength is greater than the first strength threshold, the power optimization mode is adopted. In the power optimization scenario, the compensation sub-table in the satellite communication mode is retrieved. Based on the current output power of 24.7dBm and the waveform, modulation method, and RB type of the uplink communication signal RF3, the compensation voltage ΔV1 < 0 is determined by looking up the table, that is... Figure 11 The ΔV1 shown is then used. Based on the calibration voltage Va and compensation voltage ΔV1 at point A, the target supply voltage Vb = Va + ΔV1 is calculated, thereby reducing the supply voltage of the first power amplifier 111 to the target supply voltage Vb and decoupling it from the MPR.

[0143] In satellite communication mode, for the uplink communication signal RF4 of the PUSCH channel, which has a CP waveform, uses 256QAM modulation, and has a resource block type of RB4, the current output power of the first power amplifier 111 is obtained as 16.5dBm. Figure 14Point E in the table. Then, the signal strength of the uplink communication signal RF4 is obtained. If the signal strength is less than the second strength threshold, the power optimization mode is adopted. In the power optimization scenario, the MPR is 2dBm. The current output power is increased to 18.5dBm, and the compensation sub-table in the satellite communication mode is retrieved. Based on the output power of 18.5dBm and the waveform, modulation method, and RB type of the uplink communication signal RF4, the compensation voltage ΔV3 is determined to be greater than 0 by looking up the table. Figure 14 The value of ΔV3 is shown. Then, based on the calibration voltage Ve and compensation voltage ΔV3 at point E, the target supply voltage Vh = Ve + ΔV3 is calculated, thereby increasing the supply voltage of the power amplifier to the target supply voltage Vh.

[0144] In mobile cellular communication mode, for the uplink communication signal RF5 of the PUCCH channel, which has a DFT waveform, uses QPSK modulation, and has a resource block type of RB5, the current output power of the first power amplifier 111 is obtained as 24.7dBm. Figure 12 Point A in the diagram. Then, the signal strength of the uplink communication signal RF5 is obtained. If the signal strength is greater than the first strength threshold, the power optimization mode is adopted. In the power optimization scenario, the compensation sub-table of the mobile cellular communication mode is retrieved. Based on the current output power of 24.7dBm and the waveform, modulation method, and RB type of the uplink communication signal RF5, the compensation power ΔP1 < 0 is determined by looking up the table, that is... Figure 12 The ΔP1 is shown. Then, the target power Pc = Pa + ΔP1 is calculated based on the calibration power Pa and compensation voltage ΔP1 at point A, and the corresponding target supply voltage Vc is obtained based on the target power Pc, thereby reducing the supply voltage of the first power amplifier 111 to the target supply voltage Vc and decoupling it from MPR.

[0145] In WiFi communication mode, for the uplink communication signal RF6 of the PUCCH channel, which has a CP waveform, uses 64QAM modulation, and has a resource block type of RB6, the current output power of the second power amplifier 211 is obtained as 16.5dBm. Figure 15 The G point is then identified. The signal strength of the uplink communication signal RF6 is then obtained. If the signal strength is less than the second strength threshold, the power optimization mode is adopted. In the power optimization scenario, the MPR is 2dBm. The current output power is increased to 18.5dBm, and the compensation sub-table in the WiFi communication mode is retrieved. Based on the output power of 18.5dBm and the waveform, modulation method, and RB type of the uplink communication signal RF6, the compensation power ΔP3 > 0 is determined by looking up the table. Figure 15The ΔP3 is shown. Then, the target supply voltage Pn = Ph + ΔP3 is calculated based on the calibration power Ph and compensation power ΔP3 at point H, and the corresponding target supply voltage Vn is obtained based on the target power Pn, thereby increasing the supply voltage of the second power amplifier 211 to the target supply voltage Vn.

[0146] The power calibration method provided in this application can differentiate the output power of a power amplifier based on communication scenarios such as communication mode, waveform, modulation method, bandwidth, frequency band, and RB type. It optimizes power consumption while meeting linearity requirements, and maximizes high-order modulation power in scenarios with high throughput demands. It overcomes the shortcomings of traditional technical solutions by employing a voltage compensation scheme. On the one hand, it can flexibly optimize power consumption in various scenarios, achieving a 20% reduction. On the other hand, it can flexibly increase power in high-order modulation scenarios, improving throughput in weak network conditions by up to 10%.

[0147] The power calibration method described above can subdivide the application scenarios of power amplifiers based on various dimensions such as the waveform of the radio frequency signal, the modulation method, and the position of the RB. It can optimize power consumption while meeting linearity requirements, and improve the high-order modulation power to the optimal value in scenarios with high throughput requirements.

[0149] Based on the same inventive concept, this application also provides a power calibration apparatus for implementing the power calibration method described above. The solution provided by this apparatus is similar to the implementation described in the above method; therefore, the specific limitations in one or more power calibration apparatus embodiments provided below can be found in the limitations of the power calibration method described above, and will not be repeated here.

[0150] In one embodiment, such as Figure 18As shown, a power calibration device 1800 is provided, including: an acquisition module 1801, a determination module 1802, and an adjustment module 1803. The acquisition module 1801 is used to acquire uplink communication configuration information of the communication device. The determination module 1802 is used to determine the communication mode of the communication device based on the configuration information, and to determine the target compensation dataset of the target power amplifier of the communication device based on the communication mode; wherein, the target compensation datasets are different for different communication modes.
