Referring to fig. 2, a first embodiment of the present invention provides a power consumption control method for an antenna, where the power consumption control method for an antenna is applied to a terminal, the terminal includes at least two radio frequency modules sharing a same antenna, and frequency bands of the radio frequency modules sharing the antenna are different, and the power consumption control method for an antenna includes:
step S10, determining the current signal strength of each radio frequency module sharing the antenna, and determining the target signal strength of each radio frequency module according to the current signal strength;
the terminal refers to a hardware device with a computer infrastructure, the computer infrastructure includes a controller, a memory, an input device, an output device, and the terminal is, for example, a mobile terminal such as a smart phone or a tablet computer, or a wearable device such as a smart watch; as the terminal is portable, the volume of the terminal is reduced, and the volume of the battery in the terminal is reduced, which results in a reduction in the endurance of the terminal, whereas as the communication technology is developed, the frequency bands of the antenna in the terminal are increased, the volume of the antenna is increased, and the capacity of the battery is further limited, so that the terminal is generally provided with a plurality of radio frequency modules sharing the same antenna to reduce the number of antennas in order to avoid the problem that the volume occupancy of the antenna is too large due to the excessive number of antennas; under the condition that a plurality of radio frequency modules share the same antenna, if the frequency bands of the radio frequency modules are different and the radio frequency modules need to work simultaneously, in the tuning process, if the radio frequency module of a certain frequency band is adjusted, the antenna efficiency of other radio frequency modules is possibly reduced, the power consumption of other radio frequency modules is further increased, and if the power consumption of other radio frequency modules is increased to be higher than the power consumption of the adjusted radio frequency modules, the overall power consumption of the antenna is increased; under the condition that the antenna of the terminal has a plurality of radio frequency modules which need to operate simultaneously, generally speaking, the signal quality of each radio frequency module may tend to be adjusted to an optimal state, in the adjusting process, if the signal quality of one radio frequency module is improved, the antenna efficiency of the radio frequency module is improved, the power consumption is reduced, the signal quality of the radio frequency modules of other frequency bands is reduced, the power consumption is improved, under the condition that the improved power consumption is greater than the reduced power consumption, the overall power consumption of the antenna is increased, and for some terminals with smaller battery capacity, shorter endurance is undoubtedly brought, so that the use experience of a user is reduced.
The antenna is a device for transmitting or receiving radio waves, the radio frequency module is an element or module for transmitting or processing radio frequency signals, and the frequency band, also called a band, is a small section of electromagnetic band in radio communication frequency; the reason why the number of the radio frequency modules sharing the same antenna is at least two in this embodiment is that if a certain antenna is used by only one radio frequency module, power consumption can be reduced by only increasing the signal quality when adjusting the signal quality; moreover, the frequency bands of the rf modules sharing the same antenna are different, because if the number of the rf modules sharing the same antenna is more than two but the frequency bands are the same, the power consumption of each rf module is reduced in the process of improving the signal quality, and therefore, the terminal is limited to include at least two rf modules sharing the same antenna, and the frequency bands of the rf modules sharing the same antenna are different.
The current signal strength refers to the signal strength of the radio frequency module detected by the terminal device in the current time period, and the target signal strength refers to the signal strength to which the radio frequency module is finally adjusted.
In this embodiment, in order to minimize the power consumption of the antenna in the terminal, the terminal first determines the current signal strength of each rf module sharing the antenna, so as to determine the starting point of adjustment, and further determines the target signal strength according to the current signal strength, so as to determine the ending point of adjustment; in order to minimize the overall power consumption of the antenna, it is necessary to minimize the power consumption of the antenna when each rf module in the antenna is at the target signal strength, and for this reason, the present embodiment obtains the target signal strength based on the following principle: the change relationship between the signal strength and the power consumption of each radio frequency module is measured in a laboratory, the change relationship can be a function related to the signal strength and the power consumption, it is noted that, while the change relationship between the signal strength and the power consumption of the radio frequency module of a certain antenna is measured, the change relationship between the signal strength and the power consumption of other radio frequency modules of the antenna is also measured, so as to obtain the corresponding relationship between the power consumption change and the signal strength change of each radio frequency module, for example, by simultaneously measuring the change relationship, when the signal strength of an A radio frequency module is increased from-85 dBm to-75 dBm, the signal strength corresponding to a B radio frequency module is reduced from-80 dBm to-90 dBm, based on the principle, when the current signal strength of each radio frequency module is detected, a terminal can calculate the influence of the change of each power consumption of each radio frequency module on the change of the whole power consumption of the antenna one by one, and calculating the target signal strength of each radio frequency module which enables the antenna to have the lowest power consumption.
Step S20, determining a first power consumption variation of the antenna corresponding to the adjustment of the current signal strength to the target signal strength by each rf module;
after determining the target signal strength of each radio frequency module, the terminal further needs to determine the radio frequency module to be adjusted, and when determining the radio frequency module to be adjusted, the present embodiment further determines the radio frequency module to be adjusted by determining that each radio frequency module adjusts the current signal strength to the target signal strength, and the first power consumption variation of the corresponding antenna; the terminal can calculate the power consumption change of the antenna of each radio frequency module for adjusting the current signal strength to the target signal strength one by one, and the power consumption change is used as a first power consumption variable quantity.
The first power consumption variation is a power consumption variation of the radio frequency module adjusted from the current signal strength to the target signal strength, if the current signal strength is low and the power consumption is high, after the power consumption is adjusted to the target signal strength, the power consumption is reduced, at this time, a difference between the power consumption corresponding to the target signal strength and the power consumption corresponding to the current signal strength is calculated, and the difference is taken as the first power consumption variation.
Step S30, using the radio frequency module corresponding to the minimum first power consumption variation as a target radio frequency module, and adjusting the resonance of the antenna to a resonance of a target signal strength corresponding to the target radio frequency module.
The minimum first power consumption variation can be obtained by comparing the first power consumption variations, and since the minimum first power consumption variation indicates that the power consumption of the antenna is reduced to the maximum extent, the radio frequency module corresponding to the minimum first power consumption variation is used as the target radio frequency module, and the resonance of the antenna is adjusted to the resonance of the target signal strength corresponding to the target radio frequency module.
The target radio frequency module refers to a radio frequency module to be adjusted, and the terminal controls the tuning circuit to adjust the resonant frequency during adjustment so as to adjust the target radio frequency module to the resonant frequency corresponding to the target signal strength.
In this embodiment, the current signal strength of each rf module sharing an antenna is determined, the target signal strength of each rf module is determined according to the current signal strength, it is determined that each rf module adjusts the current signal strength to the target signal strength, the first power consumption variation of the corresponding antenna, the rf module corresponding to the smallest first power consumption variation is used as the target rf module, and the resonance of the antenna is adjusted to the resonance of the target signal strength corresponding to the target rf module; under the condition that at least two radio frequency modules sharing the same antenna exist and the frequency bands of the radio frequency modules of the antenna are different, the current signal strength of each radio frequency module is determined firstly, the target signal strength of each radio frequency module is further determined, when any radio frequency module is adjusted from the current signal strength to the target signal strength, the power consumption corresponding to the radio frequency module changes, for example, when the signal strength is increased, the power consumption is reduced, when the signal strength is reduced, the power consumption is increased, therefore, the first power consumption variable quantity of the whole antenna caused when each radio frequency module adjusts the current signal strength to the target signal strength can be obtained by determining the current signal strength and the target signal strength, because the power consumption of the whole antenna can be reduced or increased, under the condition that the power consumption is reduced, the difference between the power consumption after the increase and the power consumption before the increase is a negative value, under the condition that the power consumption is increased, the difference between the increased power consumption and the power consumption before the increased power consumption is a positive value, and the smaller the first power consumption variable quantity is, the more the reduced power consumption is, so that the radio frequency module corresponding to the smallest first power consumption variable quantity is taken as the target radio frequency module, and the resonance of the antenna is adjusted to the resonance of the target signal intensity corresponding to the target radio frequency module, so that the technical effect of reducing the overall power consumption of the antenna is achieved.
Referring to fig. 3, a second embodiment of the present invention provides a method for controlling power consumption of an antenna, based on the first embodiment shown in fig. 2, where the step S20 includes:
step S21, determining each radio frequency module as the current radio frequency module;
the current radio frequency module refers to a radio frequency module which needs to calculate a first power consumption variation currently, and when the terminal determines the first power consumption variation, the terminal needs to calculate the first power consumption variation of each radio frequency module which is adjusted from the current signal strength to the target signal strength.
Step S22, determining a second power consumption variation of the antenna corresponding to the current signal strength adjusted to the target signal strength by the current rf module;
the second power consumption variation is the power consumption variation of the antenna corresponding to the current radio frequency module adjusted from the current signal strength to the target signal strength, and the calculation method of the second power consumption variation may be to determine the power consumption corresponding to the current signal strength of the current radio frequency module and the power consumption corresponding to the target radio frequency module according to the variation relationship between the power consumption of the current radio frequency module and the signal strength measured in advance, calculate the difference value obtained by subtracting the power consumption corresponding to the current radio frequency module from the power consumption corresponding to the target radio frequency module, and use the difference value as the second power consumption variation.
Step S23, determining a third power consumption variation of an antenna corresponding to each of other radio frequency modules, where the other radio frequency modules are radio frequency modules other than the current radio frequency module;
the other radio frequency modules are radio frequency modules except the current radio frequency module, the third power consumption variable quantity is the power consumption variable quantity of the antenna when the other radio frequency modules are adjusted to the corresponding target signal strength from the corresponding current signal strength, firstly, the corresponding relation between the power consumption of each other radio frequency module and the signal strength is obtained, the power consumption corresponding to the current signal strength and the power consumption corresponding to the target signal strength are determined according to the corresponding relation corresponding to each radio frequency module, the difference value of the power consumption corresponding to the target signal strength of the other radio frequency modules minus the power consumption corresponding to the current signal strength is further calculated, and the difference value is used as the third power consumption variable quantity.
Step S24, the second power consumption variation and each of the third power consumption variations are superimposed to obtain the first power consumption variation.
After the second power consumption variation and the third power consumption variation are obtained, the terminal superimposes or sums the second power consumption variation and the third power consumption variation to obtain a first power consumption variation; it should be noted that the first power consumption variation, the second power consumption variation, and the third power consumption variation are mathematical quantities obtained by subtracting the power consumption corresponding to the current signal strength from the power consumption corresponding to the target signal strength; in addition, the specific manner of calculating the first power consumption variation, the second power consumption variation, and the third power consumption variation may be changed.
In this embodiment, each radio frequency module is sequentially determined as a current radio frequency module, a second power consumption variation corresponding to the current radio frequency module adjusting the current signal strength to the target signal strength is determined, a third power consumption variation of an antenna corresponding to each other radio frequency module is determined, the second power consumption variation and the third power consumption variation are overlapped to obtain a first power consumption variation, and the antenna is further adjusted according to the first power consumption variation, so that the power consumption of the antenna is reduced.
Referring to fig. 4, a third embodiment of the present invention provides a method for controlling power consumption of an antenna, based on the first embodiment shown in fig. 2, where the step S10 includes:
step S11, determining a current signal strength of each rf module sharing the antenna, and determining a fourth power consumption variation amount for each rf module to adjust from the current signal strength to a signal strength to be adjusted;
the signal strength to be adjusted is the signal strength of the radio frequency module except the current signal strength, the fourth power consumption variation is the power consumption variation corresponding to the radio frequency module when the radio frequency module is adjusted from the current signal strength to the target signal strength, the target signal strength determined by the terminal is the target signal strength of the target radio frequency module under the condition that the power consumption of the antenna is the lowest, in order to obtain the target signal strength, the terminal needs to calculate the power consumption variation condition of the radio frequency module when the radio frequency module is adjusted from the current signal strength to each antenna corresponding to the signal strength to be adjusted, therefore, the fourth power consumption variation of each radio frequency module when the radio frequency module is adjusted from the current signal strength to the signal strength to be adjusted is determined first, and the first power consumption reduction is further obtained according to the fourth power consumption variation.
Step S12, determining a first power consumption reduction amount of the antenna according to the fourth power consumption variation amount of each rf module;
