[0021] Before introducing the technical solutions of the embodiments of the present disclosure, the related art will be described.

[0022] In the related art, a power amplifier (PA) is an important part of the radio frequency communication link inside a terminal, and not only determines the transmission power, which is an important performance indicator of the terminal, but also has a significant impact on the power consumption, which is an important performance indicator of the terminal.

[0023] Power consumption has always been a concern for devices, and how to optimize device power consumption is an issue that is being actively discussed within the industry. PAs are the "power consumption leader" of device power consumption, and device and PA manufacturers are actively working to optimize the power added efficiency (PAE) of PAs, further optimizing the power consumption performance of PAs and devices.

[0024] Figure 1 is a schematic diagram of the probability distribution of the output power of a power amplifier in a terminal when the terminal is using a real network in the related art. As shown in Figure 1, the horizontal axis represents the output power of the PA, and the vertical axis represents the occurrence probability of the output power of the PA. In the related art, when PAE optimization is performed for the full power of the PA, the actual output power of the PA is not necessarily full power, so the result of PAE optimization is relatively poor.

[0025] In other words, the related technology is unable to timely and accurately know the probability that the PA in the terminal will operate at different output powers, and therefore is unable to timely optimize the PAE to the output power with the highest PA output probability.

[0026] Based on this, in an embodiment of the present disclosure, a first parameter used to optimize and control the power-added efficiency of a power amplifier in a terminal, which corresponds to the output power that is most likely to occur within the target output power range of the power amplifier, is determined, and the power-added efficiency of the power amplifier is optimized and controlled using the first parameter.

[0027] In analog circuit design, there is a certain dependency between each design index. There is also a certain dependency between the PAE of different output powers of a PA. Optimizing the PAE design for a certain output power of a PA may result in degradation of the PAE for other output powers of the PA. Therefore, under the same set of PA parameter settings, it is only possible to achieve optimal PAE for a specific output power, which can be made relatively optimal. However, it is not possible to achieve optimal PAE for all output powers of the PA through the same set of PA parameter settings. Therefore, in order to improve PAE, it is important to know the output power at which the PA most often operates. Improving PAE is also directly related to optimizing the overall power consumption of the terminal.

[0028] FIG. 2 is a schematic diagram of the implementation flow of a control method according to an embodiment of the present disclosure, which is applied to a terminal. As shown in FIG. 2, the method includes steps 201 and 202.

[0029] In step 201, a first parameter corresponding to an output power that is most likely to occur within a target output power range of a power amplifier in a terminal is determined, and the first parameter is used to optimize and control the power-added efficiency of the power amplifier.

[0030] As can be understood, the output power of the power amplifier in the terminal has a probability distribution within the target output power range, that is, the output power of the power amplifier in the terminal may have a high or low probability of occurring.

[0031] To explain this using an example, assume that there is a peak in the probability distribution of the output power of a power amplifier in a terminal, and the target output power range corresponding to this peak is from 10 dBm to 30 dBm. Within this target output power range, the probability of 15 dBm appearing is 10%, the probability of 20 dBm appearing is 30%, and the probability of 26 dBm appearing is 60%.

[0032] In another example, assuming that there are two peaks in the probability distribution of the output power of a power amplifier in a terminal, a first target output power range corresponding to the first peak is 10 dBm to 30 dBm, a second target output power range corresponding to the second peak is 30 dBm to 40 dBm, the output power corresponding to the peak with the highest probability of occurrence in the first target output power range (i.e., the first peak) is 26 dBm, and the output power corresponding to the peak with the highest probability of occurrence in the second target output power range (i.e., the second peak) is 35 dBm, then for 26 dBm and 35 dBm, according to actual needs, the first parameter corresponding to 26 dBm and the first parameter corresponding to 35 dBm may be determined, respectively, or only the first parameter corresponding to 26 dBm or only the first parameter corresponding to 35 dBm may be determined.

[0033] It can be understood that by optimizing and controlling the power-added efficiency of the power amplifier in the terminal for the output power at which the power amplifier operates most frequently, i.e., the output power at which the power amplifier has the highest occurrence probability, the power consumption performance of the terminal can be optimized to achieve the purpose of saving power consumption of the terminal.

[0034] As can be understood, the first parameter may be an operating parameter that can be controlled so that a power amplifier in a terminal is in a PAE optimum operating state.

[0035] Hereinafter, a process of determining the first parameter corresponding to the output power that is most likely to appear within the target output power range of the power amplifier in the terminal will be described in detail.

[0036] In actual application, considering that network coverage capabilities differ in different countries or provinces, the output power that is most likely to appear within the target output power range of the power amplifier in a terminal in different countries or provinces will be different. It is also considered that changes in temperature may cause the output power that is most likely to appear within the target output power range of the power amplifier in a terminal to differ at different temperatures. Considering that the operating conditions of base stations differ in different time periods, the output power that is most likely to appear within the target output power range of the power amplifier in a terminal at different times will be different. Considering that the deployment conditions of base stations at future times will be different, the output power that is most likely to appear within the target output power range of the power amplifier in a terminal at future times will be different. Therefore, a first parameter corresponding to the output power that is most likely to appear within the target output power range of the power amplifier in a terminal can be determined by considering at least one of the conditions of the current location of the terminal, the environmental temperature where the terminal is currently located, the preset time range, and the future time.

[0037] Based on this, in one embodiment, determining a first parameter corresponding to an output power that has the highest probability of occurring within a target output power range of a power amplifier in the terminal includes: Determining a second parameter, wherein the second parameter is used to characterize at least one of a location where the terminal is currently located, an environmental temperature where the terminal is currently located, a preset time range, and a future time; Using the second parameter, determining a first parameter that corresponds to an output power that is most likely to occur within a target output power range of a power amplifier in the terminal.

[0038] As can be understood, the target output power range can be used to compile a most probable output power of the power amplifier in the terminal.

[0039] In the first type of situation, the current location of the terminal is used to determine a first parameter corresponding to the output power that is most likely to occur within the target output power range of the power amplifier in the terminal.

[0040] In practical application, considering that the output power with the highest probability of appearing within the target output power range of the power amplifier for terminals in different countries and provinces is different, first, an output power probability distribution map of the power amplifier for the terminal at the terminal's current location can be determined, and then, the output power with the highest probability of appearing within the target output power range of the power amplifier for the terminal can be determined based on the output power probability distribution map, and then, from the preset correspondence relationship between output power and operating parameters, a first parameter corresponding to the output power with the highest output probability of the power amplifier can be selected.

[0041] Based on this, in one embodiment, when the second parameter characterizes a location where the terminal is currently located, determining a first parameter corresponding to an output power that has a highest probability of occurring within a target output power range of a power amplifier in the terminal using the second parameter includes: determining an output power of a power amplifier in the terminal that is most likely to occur within a target output power range using the current location of the terminal characterized by the second parameter; and determining a first parameter based on the determined output power.

[0042] Specifically, determining an output power that is most likely to appear within a target output power range of a power amplifier in a terminal using a current location of the terminal characterized by the second parameter includes: Determining an output power probability distribution map of a power amplifier in the terminal at a current location of the terminal; and determining an output power that is most likely to occur within a target output power range of a power amplifier in a terminal based on the output power probability distribution map.

[0043] Here, the output power probability distribution maps of the power amplifier in the terminal determined at different positions are different.

[0044] As an example, for the same terminal, assume that the most probable output power of the power amplifier in the terminal in Europe is represented by Pe (dBm) and the most probable output power in China is represented by Pc (dBm). th Because the 5G network coverage in the US is denser than that in Europe, Pe > Pc. Thus, different operating parameters are set to optimize the PAE of the power amplifier for the most probable output power in different countries.

[0045] In addition, for example, since the network coverage capabilities of different provinces are different, for the same terminal, the output power probability distribution diagram of the power amplifier in the terminal in different provinces is also different. Thus, different operating parameters for optimizing the PAE of the power amplifier are set for the output power with the highest probability in different provinces.

[0046] In one case, the network operator equipment can capture the output power of the power amplifier in the terminal, calculate the occurrence probability of the output power, obtain an output power probability distribution map of the power amplifier in the terminal at the terminal's current location, and send it to the terminal, so that the terminal can determine the output power with the highest occurrence probability within the target output power range based on the output power probability distribution map, and select a first parameter corresponding to the output power with the highest probability from the preset correspondence relationship between the output power and the operating parameters to optimize the PAE of the power amplifier in the terminal.

[0047] In another case, the network operator equipment at the current location of the terminal can capture the output power of the terminal antenna port, calculate the occurrence probability of the output power, obtain a probability distribution map of the terminal antenna port at the current location of the terminal, and send it to the terminal. In this way, the terminal can add the output power of the terminal antenna port and the insertion loss of the output port of the power amplifier in the terminal to the antenna port to obtain the output power of the power amplifier in the terminal, thereby obtaining a probability distribution map of the output power of the power amplifier in the terminal at the current location of the terminal. Based on the output power probability distribution map, the terminal can determine the output power with the highest occurrence probability within the target output power range. Then, from the preset correspondence relationship between the output power and the operating parameters, a first parameter corresponding to the output power with the highest probability can be selected to optimize the PAE of the power amplifier in the terminal.

[0048] For example, if the insertion loss of the terminal power amplifier (PA) output port to the terminal antenna port is L (dBm), and the terminal's highest probability (X%) output power in the actual network is P1 (dBm), then the highest probability (X%) output power of the terminal power amplifier (PA) working in the same actual network is P1+L (dBm). Therefore, the output power of the power amplifier, i.e., P1+L (dBm), needs to be PAE optimized.

[0049] The setting of the first parameter may be stored in advance in the terminal. In this way, after determining the first parameter corresponding to the output power that is most likely to appear within the target output power range of the power amplifier in the terminal, the setting of the first parameter may be locally acquired to optimize the power-added efficiency of the power amplifier.

[0050] In practical application, the network-side server can determine an output power probability distribution map of the power amplifier in the terminal at the current location of the terminal, and determine an output power that has the highest occurrence probability within a target output power range of the power amplifier in the terminal based on the output power probability distribution map, and select a first parameter corresponding to the output power with the highest probability from the preset correspondence relationship between the output power and the operating parameters, and send the first parameter to the terminal.

[0051] Based on this, in one embodiment, when the second parameter characterizes a location where the terminal is currently located, determining a first parameter corresponding to an output power that has a highest probability of occurring within a target output power range of a power amplifier in the terminal using the second parameter includes: transmitting a current location of the terminal characterized by the second parameter to a first server, the current location of the terminal being used by the first server to determine a first parameter corresponding to an output power that is most likely to occur within a target output power range of a power amplifier in the terminal; receiving a first parameter transmitted from the first server.

[0052] The setting of the first parameter may be stored in advance in the first server on the network side. After determining the first parameter corresponding to the output power that is most likely to occur within the target output power range of the power amplifier in the terminal, the first server on the network side transmits the first parameter to the terminal, and the terminal can optimize the power-added efficiency of the power amplifier using the first parameter. Since the first parameter is not stored locally in the terminal, storage space of the terminal can be saved.

[0053] In practical application, the remote server can determine an output power probability distribution map of the power amplifier in the terminal at the current location of the terminal, determine an output power that is most likely to appear within a target output power range of the power amplifier in the terminal based on the output power probability distribution map, select a first parameter corresponding to the most likely output power from the preset correspondence relationship between output power and operating parameters, and instruct the first parameter to the terminal.

[0054] Based on this, in one embodiment, when the second parameter characterizes a location where the terminal is currently located, determining a first parameter corresponding to an output power that has a highest probability of occurring within a target output power range of a power amplifier in the terminal using the second parameter includes: transmitting a current location of the terminal characterized by the second parameter to a second server, wherein the current location of the terminal is used by the second server to determine a first parameter corresponding to an output power that is most likely to occur within a target output power range of a power amplifier in the terminal; receiving instruction information sent from the second server, the instruction information being used to indicate a first parameter; and determining the first parameter based on the instruction information.

[0055] As can be understood, the instruction information may be accompanied by the number of the first parameter.

[0056] That is, the setting of the first parameter can be stored in the terminal, and when the terminal receives the instruction information transmitted from the second server, the setting of the first parameter can be locally acquired based on the number of the first parameter.

[0057] The setting of the first parameter may be stored in the terminal. In this way, after the remote second server determines the first parameter corresponding to the output power that is most likely to occur within the target output power range of the power amplifier in the terminal, the remote second server instructs the terminal of the first parameter, and the terminal locally obtains the setting of the first parameter based on the instruction information and can optimize the power-added efficiency of the power amplifier using the first parameter. Because the second server instructs the terminal of the first parameter to be used by the terminal via the instruction information, signaling overhead is relatively small, and therefore bit overhead required for transmission can be saved.

[0058] In the second type of situation, the environmental temperature in which the terminal is currently located is used to determine a first parameter corresponding to the output power that is most likely to appear within the target output power range of the power amplifier in the terminal.

[0059] In practical application, the output power probability distribution map of the power amplifier in the terminal under the current environmental temperature is determined, and thus, based on the output power probability distribution map, the output power that is most likely to appear within the target output power range of the power amplifier in the terminal can be determined.

[0060] Based on this, in one embodiment, when the second parameter characterizes an environmental temperature where the terminal is currently located, determining a first parameter corresponding to an output power that has a highest probability of occurring within a target output power range of a power amplifier in the terminal using the second parameter, determining an output power that is most likely to occur within a target output power range of a power amplifier in the terminal using an environmental temperature where the terminal is currently located, the environmental temperature being characterized by the second parameter; and determining a first parameter based on the determined output power.

[0061] Specifically, determining an output power that is most likely to appear within a target output power range of a power amplifier in a terminal using an environmental temperature where the terminal currently resides, the environmental temperature being characterized by the second parameter, is Determining an output power probability distribution map of a power amplifier in the terminal under an environmental temperature where the terminal is currently located; and determining an output power that is most likely to occur within a target output power range of a power amplifier in a terminal based on the output power probability distribution map.

[0062] Here, the output power probability distribution diagrams of the power amplifier at the terminals determined by different temperatures are different.

[0063] In one case, the network operator equipment can capture the output power of the power amplifier in the terminal, calculate the occurrence probability of the output power, obtain a probability distribution map of the output power of the power amplifier in the terminal under the environmental temperature where the terminal is currently located, and send it to the terminal, so that the terminal can determine the output power with the highest occurrence probability within the target output power range based on the output power probability distribution map, and select a first parameter corresponding to the output power with the highest occurrence probability from the preset correspondence relationship between the output power and the operating parameters to optimize the PAE of the power amplifier in the terminal.

[0064] In another case, the network operator equipment can acquire the output power of the terminal antenna port, calculate the occurrence probability of the output power, and obtain a probability distribution map of the terminal antenna port output power under the environmental temperature where the terminal is currently located, and send it to the terminal. In this way, the terminal can add the output power of the terminal antenna port and the insertion loss of the output port of the power amplifier in the terminal to the antenna port to obtain the output power of the power amplifier in the terminal, thereby obtaining the output power probability distribution map of the power amplifier in the terminal, and determine the output power with the highest occurrence probability within the target output power range based on the output power probability distribution map. Then, from the preset correspondence relationship between the output power and the operating parameters, it can select a first parameter corresponding to the output power with the highest probability, and optimize the PAE of the power amplifier in the terminal.

[0065] Furthermore, if the terminal is in a low-temperature operating environment such as the North or South Poles for many years, the terminal can set operating parameters to the power amplifier that are more suitable for improving PAE in a low-temperature operating environment, and if the terminal is in a high-temperature operating environment such as an equatorial region for many years, the terminal can set operating parameters to the power amplifier that are more suitable for improving PAE in a high-temperature operating environment.

[0066] In a third type of situation, a preset time range is used to determine a first parameter corresponding to an output power that is most likely to occur within a target output power range of a power amplifier in a terminal.

[0067] In practical application, an output power probability distribution map of the power amplifier in the terminal in a preset time range is determined, and thus, based on the output power probability distribution map, the output power that has the highest probability of appearing within the target output power range of the power amplifier in the terminal can be determined.

[0068] Based on this, in one embodiment, when the second parameter characterizes a preset time range, determining a first parameter corresponding to an output power that has the highest probability of occurring within a target output power range of a power amplifier in a terminal using the second parameter includes: determining an output power that is most likely to occur within a target output power range of a power amplifier in a terminal using a preset time range characterized by the second parameter; and determining a first parameter based on the determined output power.

[0069] Specifically, determining an output power that is most likely to appear within a target output power range of a power amplifier in a terminal using a preset time range characterized by the second parameter includes: Determining an output power probability distribution map of a power amplifier in the terminal over a preset time range; and determining an output power that is most likely to occur within a target output power range of a power amplifier in a terminal based on the output power probability distribution map.

[0070] Here, the output power probability distribution diagram of the power amplifier of the terminal under different time periods is different, for example, the output power probability distribution diagram of the power amplifier of the terminal from 8:00 to 9:00 in the daytime is different from that from 8:00 to 9:00 in the nighttime.

[0071] In one case, the network operator equipment can capture the output power of the power amplifier in the terminal, calculate the occurrence probability of the output power, obtain a probability distribution map of the output power of the power amplifier in the terminal in a preset time range, and send it to the terminal, so that the terminal can determine the output power with the highest occurrence probability within the target output power range based on the output power probability distribution map, and select a first parameter corresponding to the output power with the highest probability from the preset correspondence relationship between the output power and the operating parameters to optimize the PAE of the power amplifier in the terminal.

[0072] In another case, the network operator equipment can acquire the output power of the terminal antenna port, calculate the occurrence probability of the output power, obtain a probability distribution map of the terminal antenna port output power within a preset time range, and send it to the terminal. In this way, the terminal can add the output power of the terminal antenna port and the insertion loss of the output port of the power amplifier in the terminal to the antenna port to obtain the output power of the power amplifier in the terminal, thereby obtaining the probability distribution map of the output power of the power amplifier in the terminal within the preset time range, and determine the output power with the highest occurrence probability within the target output power range based on the output power probability distribution map. Then, from the preset correspondence relationship between the output power and the operating parameters, a first parameter corresponding to the output power with the highest probability can be selected, and the PAE of the power amplifier in the terminal can be optimized.

[0073] In addition, if the terminal operates during the day but not at night, the terminal can set the power amplifier to operating parameters that are more suitable for improving PAE during the day. If the terminal operates during the night but not at night, the terminal can set the power amplifier to operating parameters that are more suitable for improving PAE during the night.

[0074] In the fourth type of situation, a future time is used to determine a first parameter corresponding to an output power that is most likely to appear within a target output power range of a power amplifier in the terminal.

[0075] In practical application, a probability distribution map of the output power of the power amplifier in the terminal at a future time can be determined, and thus, based on the output power probability distribution map, the output power that is most likely to appear within the target output power range of the power amplifier in the terminal can be determined.

[0076] Based on this, in one embodiment, when the second parameter characterizes a future time, determining a first parameter corresponding to an output power that has a highest probability of occurring within a target output power range of a power amplifier in a terminal using the second parameter includes: determining an output power that is most likely to occur within a target output power range of a power amplifier in a terminal using a future time characterized by the second parameter; and determining a first parameter based on the determined output power.

[0077] Specifically, determining an output power that is most likely to appear within a target output power range of a power amplifier in a terminal using a future time characterized by the second parameter includes: determining a probability distribution map of the output power of a power amplifier in the terminal at a future time; and determining an output power that is most likely to occur within a target output power range of a power amplifier in a terminal based on the output power probability distribution map.

[0078] In one case, the network operator equipment can capture the output power of the power amplifier in the terminal according to different current times, combine with a preset network model, predict the output power probability distribution map of the power amplifier in the terminal at a future time, and send it to the terminal, so that the terminal can determine the output power that has the highest probability of appearing within the target output power range based on the output power probability distribution map of the power amplifier in the terminal at a future time.

[0079] In another case, the network operator equipment can acquire the output power of the terminal antenna port according to different current times, combine with a preset network model, predict the output power probability distribution map of the terminal antenna port at a future time, and send it to the terminal. In this way, the terminal can add the output power of the terminal antenna port and the insertion loss of the output port of the power amplifier in the terminal to the antenna port to obtain the output power of the power amplifier in the terminal, thereby obtaining the output power probability distribution map of the power amplifier in the terminal at a future time, and determine the output power that has the highest probability of appearing within the target output power range based on the output power probability distribution map.

[0080] Specifically, determining an output power that is most likely to appear within a target output power range of a power amplifier in a terminal using a future time characterized by the second parameter includes: determining an output power probability distribution map of a power amplifier in the terminal at a future time and receiving the map from the network device; and determining an output power that is most likely to occur within a target output power range of a power amplifier in a terminal based on the output power probability distribution map.

[0081] However, network coverage does not remain the same even in the same area. During the evolution of a certain communication standard (e.g., 5G) from its early stage to its mature stage, the network coverage of the communication standard will be continuously strengthened, and the terminal may continuously decrease the output power that is most likely to appear in the communication standard. As the deployment of base stations in the future becomes more and more frequent, the terminal can set the power amplifier to operating parameters that are more suitable for improving the PAE in the future.

[0082] Similarly, in the process of a certain communication standard gradually being withdrawn from the network, the network coverage of that type of communication standard will continually weaken, and the terminal may continually increase the output power that is most likely to appear in that type of communication standard.

[0083] In a fifth type of situation, a first parameter corresponding to an output power that is most likely to appear within a target output power range of a power amplifier in the terminal is determined using at least one of a location where the terminal is currently located, an environmental temperature where the terminal is currently located, a preset time range, and a future time.

[0084] To explain this using an example, the output power probability distribution map of the power amplifier in the terminal at the terminal's current location and under the current environmental temperature can be determined, and based on the determined output power probability distribution map, the output power that has the highest probability of occurring within the target output power range can be determined, and operating parameters that are more suitable for improving PAE can be set for the power amplifier.

[0085] Or, An output power probability distribution map of the power amplifier in the terminal at the terminal's current location, under the current environmental temperature, and within a preset time range is determined, and based on the determined output power probability distribution map, an output power that has the highest probability of occurring within a target output power range is determined, and operating parameters that are more suitable for improving PAE can be set for the power amplifier.

[0086] In a sixth situation, when the terminal is within a coverage area of ​​a first network device, that is, the terminal and the first network device have the same location, ambient temperature, and time, the terminal can send a power margin report to the first network device, so that the first network device can determine the most probable output power of the power amplifier in the terminal. The first network device sends the determined output power to the first electronic device, which then transmits it to the terminal via the first electronic device.

[0087] Based on this, in one embodiment, determining a first parameter corresponding to an output power that is most likely to occur within a target output power range of a power amplifier in a terminal includes: determining a power margin report, the power margin report being accompanied by first information and second information, the first information characterizing a difference between a maximum transmission power allowed by the terminal and a transmission power of a currently evaluated physical uplink shared channel, and the second information characterizing a maximum allowed transmission power configured in a current serving cell and a current carrier by the terminal; sending a power margin report to a first network device, the power margin report being used by the first network device to analyze the first information and the second information and send the power margin report to the first electronic device, the first information and the second information being used by the first electronic device to: the location of the first network device; the environmental temperature where the first network device is located; Preset time ranges, and used to determine an output power that is most likely to occur within a target output power range of a power amplifier in the terminal at at least one situation in the future; receiving the output power transmitted from the first electronic device; and determining a first parameter based on the output power.

[0088] Here, the first network device may specifically refer to a base station, and the first electronic device may be a discrete device different from the first network device or may be integrated into the first network device.

[0089] As can be understood, the first information specifically refers to power headroom (PH) information, and the second information specifically refers to P CMAX Can point to information.

[0090] where: PH is the difference between the maximum transmission power allowed by the UE and the currently estimated Physical Uplink Shared Channel (PUSCH) PUSCH transmission power, and indicates how much transmission power the UE can use in addition to the transmission power currently used for PUSCH transmission. This can be simply expressed as PH = AllowedMaxTransPower - PuschPower, where AllowedMaxTransPower represents the maximum transmission power allowed by the UE, and PushPower represents the currently estimated PUSCH transmission power.

[0091] P CMAX is the maximum allowable transmission power set by the terminal in the current serving cell and the current carrier, and P CMAX already takes into account the power fallback caused by each influencing factor, such as Maximum Power Reduction (MPR). CMAX is.

[0092] As can be understood, the first network device can transmit first information and second information analyzed from power margin reports reported by a large number of terminals, as well as the location of the first network device, the environmental temperature where the first network device is located, a preset time range, and a future time to the first electronic device. In this way, the first electronic device can first calculate the real-time transmit power of the PUSCHs of a large number of terminals based on the first information and the second information. Then, select the real-time transmit power of the PUSCHs of the terminals that matches at least one of the location of the first network device, the environmental temperature where the first network device is located, the preset time range, and the future time. Finally, the corresponding probability is calculated for the selected real-time transmit power of the PUSCHs of the terminals to obtain a probability distribution map of different output powers of the terminals. The real-time transmit power of the PUSCHs of the terminals and the insertion loss of the output port of the power amplifier in the terminal to the antenna port are added to obtain the output power probability of the power amplifier in the terminal, thereby obtaining the output power probability distribution map of the power amplifier in the terminal. Finally, the output power with the highest occurrence probability within the target output power range is determined based on the obtained probability distribution map of the power amplifier in the terminal.

[0093] As can be understood, when the first network device receives the power margin report transmitted from the terminal, it analyzes the power margin report to obtain P CMAX and PH can be obtained and transmitted to the first electronic device. CMAX The real-time transmission power of the PUSCH of the current terminal is obtained by calculating the difference between PH and PH.

[0094] Furthermore, the first network device can further acquire a power margin report sent from another terminal, and analyze the power margin report to obtain a P CMAX and PH can be obtained and transmitted to the first electronic device, and the first electronic device can CMAX By calculating the difference between PH and PH, the real-time transmission power of the PUSCH of the other terminal is obtained.

[0095] In this way, after obtaining a large number of real-time PUSCH transmit powers for terminals, the first electronic device first selects the real-time PUSCH transmit powers for terminals that meet the conditions, calculates the corresponding probabilities, and obtains a terminal output power probability distribution map. Next, the real-time PUSCH transmit powers for terminals are added to the insertion loss of the output port of the power amplifier in the terminal to the antenna port to obtain the output power probability of the power amplifier in the terminal, thereby obtaining the terminal output power probability distribution map. Finally, based on the obtained terminal output power probability distribution map, the output power with the highest occurrence probability within the target output power range is determined.

[0096] Assuming that the location of the first network device is city A, the first network device receives power margin reports from a large number of terminals in city A and calculates P CMAX and PH can be analyzed and transmitted to the first electronic device, and the first electronic device CMAX By calculating the difference between PH and PH, the real-time transmission power of the terminal PUSCH is obtained, and the corresponding probability is calculated to obtain the terminal output power probability distribution map.

[0097] Or, Assuming that the environmental temperature where the first network device is located is in July or August in summer, the first network device acquires a margin report reported from a terminal in July or August in summer, and calculates P CMAX and PH can be analyzed and transmitted to the first electronic device, and the first electronic device CMAX By calculating the difference between and PH, the real-time transmission power of the terminal PUSCH is obtained, and the corresponding probability is calculated to obtain the terminal output power probability distribution map for the summer time range of July to August.

[0098] Or, Assuming that the preset time range is 12:00-13:00 in the daytime, the first network device acquires a margin report reported from a terminal in the daytime from 12:00-13:00, and calculates P CMAXand PH can be analyzed and transmitted to the first electronic device, and the first electronic device CMAX By calculating the difference between PH and PH, the real-time transmission power of the terminal PUSCH is obtained, and the corresponding probability is calculated to obtain the terminal output power probability distribution map for the time range of 12:00-13:00 in the daytime.

[0099] Or, The first network device acquires margin reports reported from a large number of terminals at different times of a day, and CMAX and PH can be analyzed and transmitted to the first electronic device, and the first electronic device CMAX By calculating the difference between PH and PH, the real-time PUSCH transmit power of the terminal is obtained, and the output power probability distribution diagram of the terminal at a certain time in the future is estimated based on the network model.

[0100] In addition, specific methods for receiving the output power with the highest probability of occurrence transmitted from the first electronic device may include a first method for directly receiving the output power with the highest probability of occurrence transmitted from the first electronic device, and a second method for receiving the output power with the highest probability of occurrence transmitted from the first electronic device via instruction information.

[0101] In addition, in order to ensure the quality of terminal transmission radio frequency indicators in different modulation methods and frequency domain positions, and to meet the electromagnetic radiation absorption ratio requirements of some scenes, MPR and Additional Maximum Power Reduction (A-MPR) are defined, which are used to instruct terminals to perform appropriate power fallback.

[0102] In addition, the terminal sends the power margin report to the network device, so that the network device can accurately control the power of the PUSCH and ensure the user's service experience. The power margin value PH is sent via a control unit of the Media Access Control (MAC) layer, and the MAC control unit involved in this process is also called a power margin report control unit.

[0103] In a seventh situation, the terminal can further receive the first parameter directly transmitted from the second electronic device.

[0104] Based on this, in one embodiment, determining a first parameter corresponding to an output power that has the highest probability of occurring within a target output power range of a power amplifier in the terminal includes: receiving a first parameter transmitted from a second electronic device; the first parameter is an operating parameter corresponding to an output power that has the highest probability of occurring within a target output power range of a power amplifier in a terminal; The output power that has the highest probability of appearing within the target output power range of the power amplifier in the terminal is determined by the second electronic device. the location of the first network device; the ambient temperature where the first network device is located; Preset time ranges, and The decision is made based on an output power probability distribution map of the power amplifier in the terminal obtained in at least one situation at a future time.

[0105] Considering that the terminal is within the coverage area of ​​a first network device, i.e., the terminal and the first network device have the same location, ambient temperature, and time, the second electronic device can first obtain the location of the first network device, the ambient temperature where the first network device is located, the preset time range, the future time, the first information, and the second information transmitted from the first network device. Thus, in at least one of the above situations, the second electronic device can use the first information and the second information to obtain an output power probability distribution map of the power amplifier in the terminal, and based on the obtained output power probability distribution map of the power amplifier in the terminal, determine the output power that is most likely to occur within the target output power range of the power amplifier in the terminal. Next, from the correspondence relationship between output power and operating parameters, the second electronic device selects a first parameter corresponding to the output power that is most likely to occur of the power amplifier. Finally, the second electronic device transmits the retrieved first parameter or a code representing the first parameter to the terminal.

[0106] In an eighth type of situation, the terminal can further obtain the first parameter locally.

[0107] Based on this, in one embodiment, determining a first parameter corresponding to an output power that has the highest probability of occurring within a target output power range of a power amplifier in the terminal includes: a first parameter is locally acquired from the terminal, the first parameter being written in advance to the terminal by a third electronic device, the first parameter being an operating parameter corresponding to an output power that has a highest probability of appearing within a target output power range of a power amplifier in the terminal, the output power that has a highest probability of appearing within a target output power range of the power amplifier in the terminal being determined by the third electronic device; the location of the first network device; the ambient temperature where the first network device is located; Preset time ranges, and The determination is based on an output power probability distribution map of the power amplifier in the terminal obtained in at least one situation of a future time; Or, a third electronic device transmits the output power having the highest probability of appearing within a target output power range of a power amplifier in the terminal to the fourth electronic device; and the third electronic device: the location of the first network device; the ambient temperature where the first network device is located; Preset time ranges, and The determination is based on an output power probability distribution map of the power amplifier in the terminal obtained in at least one situation of a future time; Or, a first parameter is locally acquired from a terminal, the first parameter being written in advance to the terminal by a fifth electronic device, the first parameter being an operating parameter corresponding to an output power that is most likely to appear within a target output power range of a power amplifier in the terminal determined by a fourth electronic device, and being transmitted to the fifth electronic device, the output power that is most likely to appear within a target output power range of a power amplifier in the terminal being transmitted to the fourth electronic device by a third electronic device, and the third electronic device: the location of the first network device; the ambient temperature where the first network device is located; Preset time ranges, and The determination is based on an output power probability distribution map of the power amplifier in the terminal obtained in at least one situation of a future time.

[0108] Considering that the terminal is within the coverage area of ​​a first network device, i.e., the terminal and the first network device have the same location, ambient temperature, and time, the third electronic device can acquire the location of the first network device, the ambient temperature where the first network device is located, the preset time range, the future time, the first information, and the second information transmitted from the first network device. Thus, in at least one of the above situations, the third electronic device can use the first information and the second information to obtain an output power probability distribution map of the power amplifier in the terminal, and based on the obtained output power probability distribution map of the power amplifier in the terminal, determine the output power that is most likely to occur within the target output power range of the power amplifier in the terminal. Next, from the correspondence relationship between output power and operating parameters, select a first parameter corresponding to the output power that is most likely to occur of the power amplifier. The first parameter is directly written to the terminal before the terminal is shipped, so that the terminal can locally acquire the first parameter.

[0109] Considering that the terminal is within the coverage area of ​​the first network device, i.e., the terminal and the first network device have the same location, ambient temperature, and time, the third electronic device can acquire the location of the first network device, the ambient temperature where the first network device is located, the preset time range, the future time, the first information, and the second information transmitted from the first network device. Thus, in at least one of the above situations, the third electronic device can use the first information and the second information to obtain an output power probability distribution map of the power amplifier in the terminal, and based on the obtained output power probability distribution map of the power amplifier in the terminal, determine the output power that is most likely to occur within the target output power range of the power amplifier in the terminal. Then, the third electronic device transmits the determined output power with the most likely occurrence to the fourth electronic device. The fourth electronic device selects a first parameter corresponding to the output power that is most likely to occur of the power amplifier from the correspondence relationship between output power and operating parameters. Before the terminal is shipped, the fourth electronic device directly writes the first parameter to the terminal, thereby allowing the terminal to locally acquire the first parameter.

[0110] Considering that the terminal is within the coverage area of ​​the first network device, i.e., the terminal and the first network device have the same location, ambient temperature, and time, the third electronic device can acquire the location of the first network device, the ambient temperature where the first network device is located, the preset time range, the future time, the first information, and the second information transmitted from the first network device. Thus, in at least one of the above situations, the third electronic device can obtain an output power probability distribution map of the power amplifier in the terminal using the first information and the second information, and determine the output power with the highest probability of occurrence within the target output power range of the power amplifier in the terminal based on the obtained output power probability distribution map of the power amplifier in the terminal. Then, the third electronic device transmits the determined output power with the highest probability of occurrence to the fourth electronic device. The fourth electronic device selects a first parameter corresponding to the output power with the highest probability of occurrence from the correspondence between output power and operating parameters and transmits it to the fifth electronic device. Before the terminal is shipped, the fifth electronic device directly writes the first parameter to the terminal, thereby allowing the terminal to locally acquire the first parameter.

[0111] Here, the third electronic device, the fourth electronic device, and the fifth electronic device may be discrete electronic devices, or may be integrated into one electronic device.

[0112] In actual application, the output power that is most likely to appear within the target output power range of the power amplifier in the terminal will differ in different cases. For example, taking the location of the terminal as an example, the most likely output power determined at location A where the terminal is located and location B where the terminal is located may be different. However, in order to optimize the PAE of the power amplifier in the terminal using the same first parameters at location A where the terminal is located and location B where the terminal is located, the most likely output powers at these two locations form a first output power range, and a first parameter corresponding to this first output power range can be searched from the preset correspondence relationship between output power and operating parameters. In this way, the searched first parameter can be used to optimize the PAE of the power amplifier in the terminal in both location A where the terminal is located and location B where the terminal is located.

[0113] Based on this, in one embodiment, the output powers that have the highest occurrence probability within the target output power range of the power amplifier in the terminal form N first output power ranges, each of which includes M output powers, where N and M are both positive integers; Here, the number of output powers included in each first output power range may be the same or different.

[0114] Specifically, it is assumed that the output powers with the highest occurrence probability within the target output power range of the power amplifier in the terminal form two first output power ranges, one of which includes M1 output powers and the other of which includes M2 output powers, where M1 may or may not be equal to M2.

[0115] As can be understood, if the network coverage capabilities within the area range in which the terminal is located are inconsistent, the output power that is most likely to occur within the target output power range of the power amplifier in the terminal may form multiple first output power ranges.

[0116] To explain by way of example, suppose the terminal is located in China, and the output power of the power amplifier in the terminal is taken from each of cities A, B, and C in China. Since the network coverage capabilities of the three cities are different, the output powers that are most likely to appear within the target output power range of the power amplifier in the terminal obtained in the three cities can form a plurality of first output power ranges. For example, the most probable output power corresponding to area 1 of city A is 15 dBm, the most probable output power corresponding to area 2 of city A is 20 dBm, and a first output power range corresponding to city A can be represented by the set {15 dBm, 20 dBm}; the most probable output power corresponding to area 1 of city B is 26 dBm, the most probable output power corresponding to area 2 of city B is 30 dBm, and a first output power range corresponding to city B can be represented by the set {26 dBm, 30 dBm}; the most probable output power corresponding to area 1 of city C is 18 dBm, and the most probable output power corresponding to area 2 of city C is 25 dBm, and a first output power range corresponding to city C can be represented by the set {18 dBm, 25 dBm}.

[0117] Furthermore, first parameters corresponding to these three first output power ranges are searched for from among the preset correspondence relationships between output power ranges and operating parameters. If the searched first parameters are all the same, the PAE of the power amplifier in the terminal is optimized using the same first parameters in city A, city B, and city C. If the searched first parameters are all different, the PAE of the power amplifier in the terminal may be optimized using different first parameters in city A, city B, and city C, or the PAE of the power amplifier in the terminal may be optimized using a first parameter corresponding to one of the cities.

[0118] Furthermore, from the preset correspondence relationships between output power ranges and operating parameters, it is possible to search for a first parameter corresponding to the most probable output power in area 1 of city A and a first parameter corresponding to the most probable output power in area 2 of city A. If the searched first parameters are the same, the power amplifier in the terminal is PAE-optimized using the same first parameters in areas 1 and 2 of city A. If the searched first parameters are different, the power amplifier in the terminal may be PAE-optimized using different first parameters in areas 1 and 2 of city A, or the power amplifier in the terminal may be PAE-optimized using a first parameter corresponding to one of the areas.

[0119] In one case, when the most probable output power of a power amplifier in a terminal in a real network forms N output power ranges (N≧1), a set of operating parameter configurations that optimizes PAE can be provided for these N output power ranges.

[0120] Furthermore, when the terminal moves from one position to another, the first output power range formed by the output power with the highest occurrence probability of the power amplifier may differ. If the first parameters corresponding to the two searched first output power ranges are the same, the PAE optimization can be performed using the same operating parameters. This eliminates the need to exchange the operating parameter configuration, thereby improving the convenience of PAE optimization.

[0121] Furthermore, when a terminal moves from one location to another, the output power with the highest probability of occurrence of the power amplifier may be different. If these two output powers belong to the same output power range, the same operating parameters can be used for PAE optimization, eliminating the need to exchange operating parameter configurations and improving the convenience of PAE optimization.

[0122] In another case, when the most probable output powers of the power amplifiers in the terminal in the actual network form N output power ranges (N≧1), N sets of operating parameter configurations that optimize the corresponding PAEs for these N most probable output power ranges can be provided.

[0123] Furthermore, by determining one set of operating parameter configurations for one output power range, N sets of operating parameter configurations can be obtained for N output power ranges, and the N PAE values ​​optimized using the obtained N sets of operating parameter configurations will be higher and the effect will be better.

[0124] In step 202, the first parameter is used to optimize and control the power added efficiency of the power amplifier.

[0125] Specifically, by adjusting the static operating point of the power amplifier in the terminal according to the first parameter, it is possible to control the power amplifier so that it is in a PAE-optimal operating state at the most probable output power.

[0126] If the static operating point Q is too high, saturation distortion will occur. Taking a triode as an example, the first parameter is the collector voltage U CE , amplification factor β, collector current I C , collector electrical resistance R C If the Q point is too high, the fundamental dynamic current is a sine wave without distortion, but the transistor will enter the saturation region (I C = βI B ), which causes a top distortion in the collector dynamic current, i.e., the collector voltage (U CE =V CC -βI C R C ) will cause bottom distortion. Similarly, if the static operating point Q is too low, cut-off distortion will occur. Similarly, taking a triode as an example, if the Q point is too low, the transistor will enter the cut-off region, causing bottom distortion in the collector dynamic current, i.e., the collector voltage (U CE =V CC -βIC R C ) generates top distortion. Therefore, an appropriate static operating point Q can be set by the first parameter. Furthermore, a metal-oxide-semiconductor field-effect transistor (MOSFET) and a triode have the same operating characteristics. When the power amplifier in a device needs to output the highest power, more attention must be paid to preventing saturation distortion, so a relatively low static operating point must be selected. On the other hand, when the power amplifier in a device needs to output a low power, the settable range of the static operating point is wider, and there is a higher probability of selecting a static operating point with higher operating efficiency.

[0127] The embodiments of the present disclosure have the following advantages. (1) By PAE-optimizing the output power at which the power amplifier in the terminal operates with the maximum probability in the actual network, an accurate PAE optimization design is realized, improving the matching and compatibility between the terminal and the actual network, and improving the power consumption performance of the entire terminal. (2) By optimizing the PAE design for the output power at which the power amplifier in the terminal operates with the maximum probability in an actual network, it is possible to obtain the same output power with a smaller power consumption, thereby saving the power consumption of the terminal.

[0128] FIG. 3 is a schematic diagram of a specific implementation flow of the control method according to the embodiment of the present disclosure, which is applied to a terminal. As shown in FIG. 3, the method includes the following steps 301 to 303:

[0129] In step 301, the terminal determines its current location.

[0130] 4 is a schematic diagram of a system framework to which the control method is applied. As shown in FIG. 4, the system includes a terminal and a parameter setting server. Here, the terminal is equipped with a location sensing module, a parameter setting module and a power amplifier.

[0131] Considering a highly mobile terminal, the current location of the terminal can be obtained through a location sensing module within the terminal.

[0132] In step 302, the output power that is most likely to appear within the target output power range of the power amplifier in the terminal is determined using the current location of the terminal, and a first parameter is determined based on the determined output power.

[0133] Here, the output powers that have the highest probability of occurring within the target output power range of the power amplifier in the terminal form N first output power ranges, each of which includes M output powers, where N and M are both positive integers.

[0134] Here, N operating parameter configurations that optimize the N PAEs for the N first output power ranges, ie, N first parameter configurations, are determined.

[0135] In the first situation, the N first parameter configurations are pre-stored in the parameter setting module of the terminal before the terminal is shipped.

[0136] Specifically, the location sensing module in the terminal senses the current location of the terminal and sends the current location of the terminal to the parameter setting module. The parameter setting module in the terminal determines the output power that is most likely to appear within the target output power range of the power amplifier in the terminal based on the current location of the terminal, and selects a first parameter that is suitable for the most likely output power from the preset correspondence between the output power and the operating parameters and sets it to the power amplifier, thereby controlling the operating state of the power amplifier and further realizing PAE optimization.

[0137] In the second situation, the parameter configuration server on the network side sends N first parameter configurations to the terminal in real time.

[0138] Specifically, a location detection module in the terminal detects the current location of the terminal and reports the current location of the terminal to a parameter setting server on the network side. The parameter setting server can determine the output power that is most likely to appear within the target output power range of the power amplifier in the terminal based on the current location of the terminal, and select a first parameter suitable for the most likely output power from the preset correspondence between the output power and the operating parameters and send it to the terminal. The parameter setting module in the terminal can set the received first parameter in the power amplifier to control the operating state of the power amplifier and further achieve PAE optimization.

[0139] In the third situation, the remote parameter setting server instructs the parameter setting module inside the terminal to perform parameter selection for PAE optimization design.

[0140] Specifically, the location sensing module of the terminal device reports the sensed current location to a remote parameter setting server. The parameter setting server determines the output power that is most likely to appear within the target output power range of the power amplifier in the terminal based on the terminal's current location, selects a first parameter suitable for the most likely output power from preset correspondences between output power and operating parameters, and instructs the selected first parameter to the terminal via instruction information. The parameter setting module in the terminal locally obtains the first parameter based on the instruction information and sets it in the power amplifier to control the operating state of the power amplifier and further achieve PAE optimization.

[0141] In step 303, the first parameter is used to optimize and control the power added efficiency of the power amplifier.

[0142] Specifically, by adjusting the static operating point of the power amplifier in the terminal according to the first parameter, it is possible to control the power amplifier so that it is in a PAE-optimal operating state at the most probable output power.

[0143] Figure 5 is a schematic diagram of the static operating point of a power amplifier. As shown in Figure 5, when amplifying an AC signal, if the static operating point of the power amplifier is too high, saturation distortion may occur, and if the static operating point of the power amplifier is too low, cutoff distortion may occur. Therefore, to satisfy the nonlinear performance of large signals and prevent distortion in the power amplifier, the static operating point generally needs to be located at the midpoint. For small signals, the above restrictions do not apply. The large signal refers to a signal with a large power input to the power amplifier, and the small signal refers to a signal with a small power input to the power amplifier. Other factors such as power consumption can also be taken into consideration when selecting the static operating point. Therefore, by adjusting the static operating point, it is possible to simultaneously optimize nonlinear performance at high power output and efficiency at low power output.

[0144] FIG. 6 is a schematic diagram of the optimization result of the power added efficiency of the power amplifier. As shown in FIG. 6, by adjusting the static operating point of the power amplifier in the terminal using the first parameter, the power amplifier can be controlled to be in an optimal PAE operating state. The PAE curve after adjustment has a clear improvement in the power added efficiency of the power amplifier compared to the PAE curve before adjustment.

[0145] This example has the following advantages. (1) Using the current location of the terminal, the output power at which the power amplifier in the terminal operates with the greatest probability in the actual network is determined, and then PAE optimization is performed using a first parameter appropriate for the output power with the highest probability, thereby reducing the power consumption of the terminal.
