[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 in a radio frequency communication link inside a terminal, and not only determines the transmission power, which is an important performance indicator of a terminal, but also has an important impact on the power consumption, which is an important performance indicator of a terminal.

[0023] Terminals have always been concerned about power consumption, and how to optimize terminal power consumption is an issue that is being actively discussed within the industry. PA is the "power consumption leader" of terminal power consumption, and terminal and PA manufacturers are actively working on optimizing PA's Power Added Efficiency (PAE) to further optimize the power consumption performance of PA and terminal.

[0024] Figure 1 is a schematic diagram of the probability distribution of the output power of the power amplifier in a terminal when the terminal uses the actual 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 performing PAE optimization 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 cannot timely and accurately know the probability that the PA in the terminal will operate at different output powers, and therefore cannot realize timely optimization of 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 an output power that is most likely to occur within a 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 addition, there is a certain dependency between each design index for analog circuit design. There is also a certain dependency between the PAE of different output powers of PA. Optimization design of PAE for a certain output power of PA may lead to degradation of PAE for other output powers of PA. Therefore, under the same set of PA parameter settings, it is only possible to realize optimization of PAE for a certain output power, which can be made relatively optimal, but it is not possible to realize PAE optimization 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 operates most often, and the improvement of PAE is also directly related to the optimization of the overall power consumption of the terminal.

[0028] FIG. 2 is a schematic diagram of an 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 probability of the output power of the power amplifier in the terminal occurring may be large or small.

[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 the 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 from 10 dBm to 30 dBm, a second target output power range corresponding to the second peak is from 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, for 26 dBm and 35 dBm, according to actual needs, a first parameter corresponding to 26 dBm and a first parameter corresponding to 35 dBm may be determined, respectively, or only a first parameter corresponding to 26 dBm or only a first parameter corresponding to 35 dBm may be determined.

[0033] As can be understood, by optimizing and controlling the power-added efficiency of a power amplifier in a terminal for the output power at which the power amplifier is most likely to operate, 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 appreciated, the first parameter may be an operating parameter that is controllable such 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 practical application, considering that the network coverage capabilities of different countries and provinces are different, the output power with the highest probability of appearing within the target output power range of the power amplifier in the terminal in different countries and provinces will be different. Considering that the change in temperature may cause the output power with the highest probability of appearing within the target output power range of the power amplifier in the terminal at different temperatures to be different. Considering that the operating state of the base station in different time periods is different, the output power with the highest probability of appearing within the target output power range of the power amplifier in the terminal at different times will be different. Considering that the deployment situation of the base station at a future time is different, the output power with the highest probability of appearing within the target output power range of the power amplifier in the terminal at a future time will be different. Therefore, the first parameter corresponding to the output power with the highest probability of appearing within the target output power range of the power amplifier in the terminal can be determined by considering at least one of the situation of the location where the terminal is currently located, 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 is most likely to occur within a target output power range of a power amplifier in the terminal includes: Determining a second parameter, the second parameter being 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 a 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 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.

[0040] In practical application, considering that the output power with the highest probability of occurrence within the target output power range of the power amplifier in terminals of different countries and provinces is different, first determine the output power probability distribution map of the power amplifier in the terminal at the current location of the terminal, 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 output power probability distribution map. Then, select a first parameter corresponding to the output power with the highest output probability of the power amplifier from the preset correspondence relationship between the output power and the operating parameters.

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

[0042] Specifically, 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 current location of the terminal characterized by the second parameter, 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 Pe>Pc because the 5G (First Generation) network coverage in China is denser than that in Europe. Thus, different operating parameters for PAE optimization of the power amplifier are set for the most probable output power in different countries.

[0045] In addition, for example, the network coverage capabilities of different provinces are different, so for the same terminal, the output power probability distribution diagrams of the power amplifier in the terminal in different provinces are also different. Thus, different operating parameters are set for optimizing the PAE of the power amplifier 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, collect statistics on the occurrence probability of the output power, obtain an output power probability distribution map of the power amplifier in the terminal at the current location of the terminal, 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 according to 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 optimize the PAE of the power amplifier in the terminal.

[0047] In another case, the network operator equipment at the location where the terminal is currently located can capture the output power of the terminal antenna port, collect statistics on the occurrence probability of the output power, obtain the output power probability distribution map of the terminal antenna port at the location where the terminal is currently located, and send it to the terminal; thus, the terminal can obtain the output power probability distribution map of the power amplifier in the terminal at the location where the terminal is currently located by adding 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, and determine the output power with the highest occurrence probability within the target output power range according to the output power probability distribution map. Then, the first parameter corresponding to the output power with the highest probability can be selected from the preset correspondence relationship between the output power and the operating parameters, and the PAE of the power amplifier in the terminal can be optimized.

[0048] Take an example, if the insertion loss of the output port of the power amplifier (PA) in the terminal to the terminal antenna port is L (dBm), and the output power with the highest probability (X%) in the actual network of the terminal is P1 (dBm), the output power with the highest probability (X%) that the power amplifier (PA) in the terminal will work 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 manner, 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 setting of the first parameter may be locally obtained 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, 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, select a first parameter corresponding to the output power with the highest probability from a 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, using the second parameter 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, 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; and 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. In this way, 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, it is possible to save storage space in the terminal.

[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 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, select a first parameter corresponding to the output power with the highest occurrence probability from a preset correspondence relationship between the output power and the 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, using the second parameter 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, Transmitting a current location of the terminal characterized by the second parameter to a second server, the current location of the terminal being 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 transmitted 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. When the terminal receives the instruction information transmitted from the second server, the terminal can locally acquire the setting of the first parameter based on the number of the first parameter.

[0057] In addition, 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 first parameter to the terminal, 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. Since the second server instructs the terminal of the first parameter to be used by the terminal via the instruction information, the signaling overhead is relatively small, and therefore the bit overhead required for transmission can be saved.

[0058] In the second type of situation, the environmental temperature in which the terminal currently resides 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 the terminal.

[0059] In practical application, an 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, an 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, using the second parameter 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, 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 in which the terminal is currently located, the environmental temperature being characterized by the second parameter; Determining a first parameter based on the determined output power.

[0061] Specifically, determining an output power that is most likely to occur within a target output power range of a power amplifier in a terminal by using an environmental temperature where the terminal currently exists, the environmental temperature being characterized by the second parameter, 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 of different temperature determination are different.

[0063] In one case, the network operator equipment can capture the output power of the power amplifier in the terminal, collect statistics on 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 according to 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 optimize the PAE of the power amplifier in the terminal.

[0064] In another case, the network operator equipment can capture the output power of the terminal antenna port, collect statistics on the occurrence probability of the output power, obtain a probability distribution map of the output power of the terminal antenna port under the environmental temperature where the terminal is currently located, and send it to the terminal; thus, the terminal can obtain the output power probability distribution map of the power amplifier in the terminal by adding 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, and determine the output power with the highest occurrence probability within the target output power range according to the output power probability distribution map. Then, the first parameter corresponding to the output power with the highest probability can be selected from the preset correspondence relationship between the output power and the operating parameters, and the PAE of the power amplifier in the terminal can be optimized.

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

[0066] In a third situation, the 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 the 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 occurring 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 is most likely to occur within a target output power range of a power amplifier in a terminal using the second parameter, comprises: 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; Determining a first parameter based on the determined output power.

[0069] Specifically, 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 includes: Determining an output power probability distribution map of a power amplifier in a 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 ranges 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 and from 8:00 to 9:00 in the nighttime are different.

[0071] In one case, the network operator equipment can capture the output power of the power amplifier in the terminal, collect statistics on 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 according to 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 optimize the PAE of the power amplifier in the terminal.

[0072] In another case, the network operator equipment can capture the output power of the terminal antenna port, collect statistics on the occurrence probability of the output power, obtain a probability distribution map of the output power of the terminal antenna port in a preset time range, and send it to the terminal, in this way, the terminal can obtain the output power probability distribution map of the power amplifier in the terminal in a preset time range by adding 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, and determine the output power with the highest occurrence probability within the target output power range according to the output power probability distribution map. Then, from the preset correspondence relationship between the output power and the operating parameters, the 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 more suitable for improving the PAE during the day. If the terminal operates at night but not at day, the terminal can set the power amplifier to operating parameters more suitable for improving the PAE during the night.

[0074] In a fourth type of situation, a future time 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 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, an 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.

[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 is most likely to occur 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; Determining a first parameter based on the determined output power.

[0077] Specifically, 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 includes: determining a probability distribution map of an output power of a power amplifier at 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 capture 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 obtain the output power probability distribution map of the power amplifier in the terminal at a future time by adding 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, 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 occur 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 same 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, the network coverage does not change even in the same area. In the process of evolution from the early stage to the mature stage of a certain communication standard (e.g., 5G), the network coverage of the communication standard is constantly strengthened, and the terminal may constantly decrease the output power that is most likely to appear in the communication standard. As the deployment of base stations in the future increases, the terminal can set the power amplifier to an operating parameter that is more suitable for improving the PAE at a future time.

[0082] Similarly, in the process of a certain communication standard being gradually 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 occur 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 with an example, an output power probability distribution map of a power amplifier in a terminal at a location where the terminal is currently located and under an environmental temperature where the terminal is currently located 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 in the power amplifier.

[0085] Or, An output power probability distribution map of a power amplifier in a terminal at a current location, under a 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, considering that the terminal is within a first network device coverage area, that is, the terminal and the first network device have the same location, environmental temperature and time, the terminal can send a power margin report to the first network device, so that the first network device determines the output power with the highest output probability of the power amplifier in the terminal. The first network device sends the determined output power to the first electronic device, and it is transmitted 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; and 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; an environmental temperature in which the first network device is located; Preset time ranges, and is 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 terminal and the currently evaluated Physical Uplink Shared Channel (PUSCH) PUSCH transmission power, and indicates how much transmission power is available for the terminal in addition to the transmission power currently used for PUSCH transmission. It can be simply expressed as PH = AllowedMaxTransPower - PuschPower, where AllowedMaxTransPower represents the maximum transmission power allowed by the terminal, and PuschPower represents the currently evaluated 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 CMAX already takes into account the power fallback caused by each influencing factor such as Maximum Power Reduction (MPR). CMAX It is.

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

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

[0094] In addition, the first network device can further obtain a power margin report transmitted 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 receive P CMAX By calculating the difference between PH and PH, the real-time transmission power of the PUSCH of the other terminals is obtained.

[0095] In this way, after obtaining a large number of real-time transmission powers of terminal PUSCHs, the first electronic device first selects the real-time transmission powers of terminal PUSCHs that meet the conditions, calculates the corresponding probabilities, and obtains the terminal output power probability distribution map. Then, the real-time transmission powers of terminal PUSCHs 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, and obtains the output power probability distribution map of the power amplifier in the terminal. Finally, based on the obtained output power probability distribution map of the power amplifier in the terminal, 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 acquires 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 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-August in summer, the first network device obtains a margin report reported from a terminal in July-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, the corresponding probability is calculated, and a probability distribution map of the terminal output power in the summer time range of July to August is obtained.

[0098] Or, Assuming that the preset time range is 12:00-13:00 in the daytime, the first network device obtains a margin report from a terminal during the daytime from 12:00-13:00, and CMAXand 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, the corresponding probability is calculated, and the terminal output power probability distribution map in the daytime range of 12:00-13:00 is obtained.

[0099] Or, The first network device acquires margin reports 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 P, the real-time transmission power of the terminal PUSCH is obtained, and the output power probability distribution map 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, for the purpose of ensuring the quality of terminal transmission radio frequency indicators in different modulation methods and frequency domain positions, and meeting the electromagnetic radiation absorption ratio requirements of some scenes, MPR and Additional Maximum Power Reduction (A-MPR) are defined, which are used to instruct the terminal 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 business experience. The value of the power margin PH is sent through a control unit of a media access control (MAC) layer, and the MAC control unit related to 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 a second electronic device.

[0104] 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 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 is most likely to occur 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. a location of the first network device; the environmental temperature in which the first network device is located; Preset time ranges, and The determination is based on a probability distribution map of the output power of the power amplifier in the terminal obtained in at least one situation of a future time.

[0105] In addition, considering that the terminal is within the coverage area of ​​the first network device, that is, the terminal and the first network device have the same location, environmental temperature and time, first, the second electronic device can obtain the location where the first network device is located, the environmental 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, and thus, in at least one of the above situations, the second 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 based on the obtained output power probability distribution map of the power amplifier in the terminal, determine the output power with the highest occurrence probability within the target output power range of the power amplifier in the terminal. Next, from the correspondence relationship between the output power and the operating parameters, select the first parameter corresponding to the output power with the highest occurrence probability of the power amplifier. Finally, the second electronic device transmits the searched first parameter or a code representing the first parameter to the terminal.

[0106] In an eighth situation, the terminal is further capable of locally acquiring the first parameter.

[0107] 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 the terminal includes: and locally acquiring a first parameter from the terminal, the first parameter being written in advance by a third electronic device to the terminal, the first parameter being an operation 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. a location of the first network device; the environmental temperature in which the first network device is located; Preset time ranges, and The determination is based on an output power probability distribution map of a power amplifier in the terminal obtained in at least one situation of a future time; Or, a fourth electronic device that writes the first parameter to the terminal in advance; the first parameter is an operating 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, the output power being determined by the fourth electronic device; the output power that is most likely to occur within a target output power range of a power amplifier in the terminal is transmitted by a third electronic device to the fourth electronic device; and the third electronic device: a location of the first network device; the environmental temperature in which the first network device is located; Preset time ranges, and The determination is based on an output power probability distribution map of a 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 by a fifth electronic device to the terminal, the first parameter being an operating parameter corresponding to an output power having a highest probability of occurrence 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 having a highest probability of occurrence within a target output power range of a power amplifier in the terminal being transmitted by a third electronic device to the fourth electronic device, and the third electronic device: a location of the first network device; the environmental temperature in which the first network device is located; Preset time ranges, and The determination includes determining the power supply voltage based on a probability distribution map of the output power of a power amplifier in the terminal obtained in at least one situation of a future time.

[0108] In addition, considering that the terminal is within the coverage area of ​​the first network device, that is, the terminal and the first network device have the same location, environmental temperature and time, the third electronic device can obtain the location where the first network device is located, the environmental 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, and 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 based on the obtained output power probability distribution map of the power amplifier in the terminal, determine the output power that has the highest occurrence probability within the target output power range of the power amplifier in the terminal. Then, from the correspondence relationship between the output power and the operating parameters, select the first parameter corresponding to the output power that has the highest occurrence probability of the power amplifier. Before the terminal is shipped, the first parameter is directly written into the terminal, and thus the terminal can locally obtain the first parameter.

[0109] In addition, considering that the terminal is within the coverage area of ​​the first network device, that is, the terminal and the first network device have the same location, environmental temperature and time, the third electronic device can obtain the location where the first network device is located, the environmental 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, and 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 based on the obtained output power probability distribution map of the power amplifier in the terminal, determine the output power with the highest occurrence probability within the target output power range of the power amplifier in the terminal. Then, transmit the determined output power with the highest occurrence probability to the fourth electronic device. The fourth electronic device selects the first parameter corresponding to the output power with the highest occurrence probability of the power amplifier from the correspondence relationship between the output power and the operating parameters. Before the terminal is shipped, the fourth electronic device directly writes the first parameter to the terminal, and thus the terminal can locally obtain the first parameter.

[0110] In addition, considering that the terminal is within the coverage area of ​​the first network device, that is, the terminal and the first network device have the same location, environmental temperature and time, the third electronic device can obtain the location where the first network device is located, the environmental 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, and 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 based on the obtained output power probability distribution map of the power amplifier in the terminal, determine the output power with the highest occurrence probability within the target output power range of the power amplifier in the terminal. Then, transmit the determined output power with the highest occurrence probability to the fourth electronic device. The fourth electronic device selects the first parameter corresponding to the output power with the highest occurrence probability of the power amplifier from the correspondence relationship between the output power and the 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, and thus the terminal can locally obtain 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 practical application, taking into consideration that the output power with the highest probability of occurrence within the target output power range of the power amplifier in the terminal is different in different cases, for example, taking the location where the terminal is located as an example, the output power with the highest probability of being determined at location A where the terminal is located and location B where the terminal is located may be different, but in order to optimize the PAE of the power amplifier in the terminal using the same first parameter at location A where the terminal is located and location B where the terminal is located, the output power with the highest probability at these two locations forms a first output power range, and a first parameter corresponding to the first output power range can be searched from the preset correspondence relationship between the output power and the operating parameters, and in this way, the PAE of the power amplifier in the terminal can be optimized using the searched first parameter 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 having 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 the first output power ranges including 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 first output power range includes M1 output powers, and the other first output power range includes M2 output powers, where M1 may be equal to M2 or M1 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, this may cause the output power that has the highest probability of occurring within the target output power range of the power amplifier in the terminal to form multiple first output power ranges.

[0116] To explain by example, assume that the terminal is located in China, and the output power of the power amplifier in the terminal is taken from each of Chinese cities A, B, and C. Since the network coverage capabilities of the three cities are different, the output powers obtained in the three cities that have the highest probability of appearing within the target output power range of the power amplifier in the terminal can form a plurality of first output power ranges. For example, the output power that is most likely to correspond to area 1 of city A is 15 dBm, the output power that is most likely to correspond to area 2 of city A is 20 dBm, and the first output power range corresponding to city A can be represented by the set {15 dBm, 20 dBm}, the output power that is most likely to correspond to area 1 of city B is 26 dBm, the output power that is most likely to correspond to area 2 of city B is 30 dBm, and the first output power range corresponding to city B can be represented by the set {26 dBm, 30 dBm}, the output power that is most likely to correspond to area 1 of city C is 18 dBm, the output power that is most likely to correspond to area 2 of city C is 25 dBm, and the 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 the output power ranges and the operating parameters. If the searched first parameters are all the same, the power amplifier in the terminal is PAE optimized using the same first parameters in city A, city B, and city C. If the searched first parameters are all different, the power amplifier in the terminal may be PAE optimized using different first parameters in city A, city B, and city C, or the power amplifier in the terminal may be PAE optimized using a first parameter corresponding to a certain city among them.

[0118] Furthermore, from the preset correspondence relationship between the output power range and the operation parameters, 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 can be searched. 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 a certain area.

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

[0120] In addition, when the terminal moves from one location to another, the first output power range formed by the output power with the highest occurrence probability of the power amplifier may be different. 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, and there is no need to exchange the operating parameter configuration, thereby improving the convenience of the PAE optimization.

[0121] In addition, when a terminal moves from one location to another, the output power with the highest occurrence probability 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 to perform PAE optimization, and there is no need to exchange the operating parameter configuration, which improves the convenience of PAE optimization.

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

[0123] In addition, 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 are higher and have better effects.

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

[0125] Specifically, the static operating point of the power amplifier in the terminal is adjusted by the first parameter, thereby controlling the power amplifier to be 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 base current is a sine wave without distortion, but the transistor will enter the saturation region (I C = βI B ), a top distortion occurs in the collector dynamic current, that is, the collector voltage (U CE =V CC -βI C R C ) will have 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. Moreover, a metal-oxide-semiconductor field-effect transistor (MOSFET) and a triode have the same operating characteristics. When the power amplifier in the terminal needs to output the highest power, more attention should be paid to preventing saturation distortion, so a relatively low static operating point should be selected. On the other hand, when the power amplifier in the terminal needs to output a small power, the settable range of the static operating point is larger, and the probability of selecting a static operating point with higher operating efficiency is higher.

[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, which improves the matching and compatibility between the terminal and the actual network, and improves 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 less 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 frame in which the control method is applied, and as shown in FIG 4, the system includes a terminal and a parameter setting server, where the terminal is equipped with a location sensing module, a parameter setting module and a power amplifier.

[0131] In this regard, in the case of a terminal having high mobility, the current location of the terminal can be obtained through a location sensing module inside the terminal.

[0132] In step 302, an output power that is most likely to occur within a target output power range of a 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 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.

[0134] Here, 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 type of situation, the N first parameter configurations are pre-stored in a parameter setting module of the terminal before the terminal is shipped.

[0136] Specifically, a location sensing module in the terminal senses a location where the terminal is currently located, and transmits the location where the terminal is currently located to a parameter setting module. The parameter setting module in the terminal determines an output power that has the highest probability of appearing within a target output power range of the power amplifier in the terminal based on the location where the terminal is currently located, and selects a first parameter suitable for the output power with the highest probability from the preset correspondence relationship 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 setting server on the network side sends the N first parameter configurations to the terminal in real time.

[0138] Specifically, the location sensing module in the terminal senses the location where the terminal is currently located and reports the location where the terminal is currently located 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 location where the terminal is currently located, 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 realize PAE optimization.

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

[0140] Specifically, the position sensing module of the terminal device reports the sensed current position 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 current location of the terminal, selects a first parameter suitable for the most likely output power from the preset correspondence between the output power and the operating parameters, and indicates 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, thereby controlling the operating state of the power amplifier and further realizing 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, the static operating point of the power amplifier in the terminal is adjusted by the first parameter, thereby controlling the power amplifier to be in a PAE-optimal operating state at the most probable output power.

[0143] FIG. 5 is a schematic diagram of the static operating point of a power amplifier. As shown in FIG. 5, when amplifying an AC signal, if the static operating point of the power amplifier is too high, saturation distortion may occur, or if the static operating point of the power amplifier is too low, cut-off distortion may occur. Therefore, in order to meet the nonlinear performance of a large signal and prevent the power amplifier from generating distortion, it is generally necessary to place the static operating point at the midpoint position. For a small signal, there is no such restriction. The large signal is a signal input to the power amplifier with a large power, and the small signal is a signal input to the power amplifier with a small power. The selection of the static operating point can also take into account other factors such as power consumption. Therefore, by adjusting the static operating point, it is possible to simultaneously achieve optimization of nonlinear performance at high power output and optimization of efficiency at low power output.

[0144] FIG. 6 is a schematic diagram of the optimization result of the power added efficiency of a 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. Compared with the PAE curve before adjustment, the PAE curve after adjustment has obviously improved the power added efficiency of the power amplifier.

[0145] This embodiment 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 physical network is determined, and the terminal's power consumption can be saved by performing PAE optimization using a first parameter suitable for the output power with the highest probability.
