Detailed Description
The embodiment of the application provides a method for adjusting power of electronic equipment, the electronic equipment and a storage medium, which are used for ensuring that the index of PA can meet the requirement when the final power adjustment is finished because of the temperature and other differences of signaling environment of the electronic equipment, and the power consumption is not higher.
In order for those skilled in the art to better understand the present application, the following description will describe embodiments of the present application with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. Based on the examples in this application, all shall fall within the scope of protection of this application.
As shown in fig. 1, is a basic architecture diagram of a transmission path of a terminal device at present. The basic architecture of the current mainstream terminal equipment such as mobile phone and transmitting path is basically the architecture diagram shown in fig. 1.
Referring to the architecture diagram of fig. 1, a dc-dc converter (Direct Current Direct Current Converter, DCDC) supplies Power to a Power Amplifier (PA), and the Power consumption of the PA is affected by the supply voltage of the DCDC, which is specifically related to the following relationship:
when the PA output power is a certain constant value, the higher the DCDC output voltage, the lower the PA efficiency, and the higher the power consumption, but the lower the adjacent channel leakage ratio (Adjacent Channel Leakage Ratio, ACLR) at this time, the better the ACLR index; conversely, the smaller the output voltage of DCDC, the higher the efficiency of PA and the smaller the power consumption, but at this time, the larger the ACLR, the worse the ACLR index. The standard of the communication protocol is required for ACLR, so that the output voltage of DCDC cannot be reduced without limitation, and ACLR must be ensured to meet the requirement.
It is currently the mainstream practice that, according to the characteristics of PA, in case of meeting ACLR requirements, we obtain a table of correspondence between the output power of PA (denoted as Pout) and the minimum supply voltage required to meet ACLR requirements (denoted as VCC) (i.e. a table of Pout vs. VCC) by measurement.
Then, in the process of calibrating the terminal equipment, the table of Pout vs. VCC is called, the specific value of automatic gain control (Auto Gain Control, AGC) of an internal Transmitter (Transmitter) of a radio frequency transceiver chip (Radio Frequency Integrated Circuits, RFIC) required when Pout=23 dBm is to be calibrated, the table is firstly used for inquiring the VCC value (such as 3.4V) at the moment, the output of DCDC is set to be 3.4V and PA is opened, then the internal Transmitter is opened and the output power of the internal Transmitter is changed by traversing the AGC value from large to small, the AGC value required when Pout=23 dBm is found, and the relationship of AGC vs. Pout vs. VCC when Pout=23 dBm is found; then the same method finds the required tables of AGC vs. Pout vs. VCC at all power points and finally writes the tables into the storage file of the terminal equipment.
Thus, the whole calibration process is completed, and when the terminal equipment works under the signaling, the terminal equipment firstly receives the power control command sent by the base station to adjust the self transmitting power.
For example, the base station requests the transmitting power of the terminal device to be Pout1, and after receiving the power value, the terminal device sets the AGC value and the VCC value according to the table generated by calibration in the storage file to output the specified power.
Since the actual signaling environment and the environment temperature during calibration will have different conditions, the gains of PA and Transmitter will fluctuate, so there will be a difference between the actual AGC and VCC output power according to the table and the target power. The method is to detect the difference between the actual output power and the target power through a power feedback loop and dynamically adjust parameters such as AGC to make the final actual output power equal to the target power.
For the traditional power transmission flow of the terminal equipment, due to the difference of conditions such as temperature of a calibration environment and an actual working signaling environment, the AGC value called by outputting the same target power in the final signaling environment is different, and the difference may be more than +/-3 dB in extreme scenes.
For example, in a calibration environment, agc=60, vcc=3.4v is set, and the output power is 23dBm; however, the actual output power fluctuates due to the fluctuation of the PA gain caused by the fluctuation of conditions such as temperature and the like in the signaling environment; assuming that the actual gain of the PA increases by 3dB in the extreme low temperature environment, then the output power in the signaling reaches 26dBm at the beginning, the terminal device needs to adjust through power feedback, and finally decreases agc=57, and then the corresponding VCC changes, for example, decreases to 2.6V, and finally controls the output power in the environment to be about 23 dBm.
However, for the PA itself, the output power remains unchanged, but the power supply voltage decreases, and the ACLR index becomes worse, so that the standard of the communication protocol is not satisfied; if the actual gain of the PA is reduced in a high temperature environment, the AGC value is correspondingly increased, and the corresponding VCC is also increased, so that the PA power consumption is too high.
The network device may be a macro base station, a micro base station (also referred to as a "small base station"), a pico base station, an Access Point (AP), a transmission point (transmission point, TP), a new generation base station (new generation Node B, gNodeB), or the like of a Long Term Evolution (LTE) system, a New Radio (NR) system, or an evolved base station (evolutional node B, which may be simply referred to as an eNB or an e-NodeB) in an licensed assisted access long term evolution (LAA-LTE) system.
The electronic device referred to in the present application may be a terminal device, or may be other electronic devices using a radio frequency PA. Among these, terminal devices, which may be referred to as User Equipment (UE), mobile Station (MS), mobile terminal (mobile terminal), intelligent terminal, etc., may communicate with one or more core networks via a radio access network (radio access network, RAN). For example, the terminal device may be a mobile phone (or "cellular" phone), a computer with a mobile terminal, etc., as well as portable, pocket, hand-held, computer-built-in or car-mounted mobile devices and terminal devices in future NR networks that exchange voice or data with the radio access network. Description of terminal device: in this application, the terminal device may also include a Relay, and both the Relay and the base station may perform data communication may be regarded as a terminal device, which will be described in the general sense of UE in this application.

Optionally, the electronic device adjusting the AGC value when the first actual output power and the target power are not equal, and keeping the VCC value unchanged, to obtain an adjusted first AGC value may include:
if the first actual output power is greater than the target power, the electronic equipment subtracts 1 from the AGC value, and keeps the VCC value unchanged, so as to obtain a first AGC value after subtracting 1;
if the first actual output power is smaller than the target power, the electronic equipment adds 1 to the AGC value, and keeps the VCC value unchanged, so as to obtain a first AGC value added with 1;
or alternatively, the first and second heat exchangers may be,

and if the first actual output power is smaller than the target power, the electronic equipment adds 2 to the AGC value, and keeps the VCC value unchanged, so as to obtain a first AGC value after adding 2.
Illustratively, after the power feedback loop in the electronic device measures the first actual output power Pout1 of the PA output port at this time, the first actual output power Pout1 is compared with the target power Pout 0. If Pout1< Pout0 at this time, the corresponding AGC value is increased by 1, and the voltage value of VCC is kept unchanged; if Pout1> Pout0 at this time, the corresponding AGC value is decremented by 1 and the voltage value of VCC is maintained.

If pout2=pout0, that is, the actual output power is equal to the target power, the power adjustment is stopped.
According to the technical scheme, the novel scheme is provided for overcoming the defects of the traditional scheme, the power consumption under the signaling environment with different conditions such as actual temperature can be optimized, and the requirement of ACLR is met. The utility model provides a new electronic equipment power adjustment mode, through the value that keeps VCC always in the electronic equipment power adjustment process, for the mode of the VCC value that target power Pout corresponds in the calibration table, only change the AGC value of RFIC, finally realize that electronic equipment can satisfy the requirement because the temperature etc. of signalling environment is different when carrying out power adjustment and accomplish the index of PA, the consumption also can not be too high.

309. And stopping power adjustment by the electronic equipment under the condition that the third actual output power is equal to the target power.
Illustratively, after the power feedback loop in the electronic device measures the third actual output power Pout3 of the PA output port at this time, the third actual output power Pout3 is compared with the target power Pout 0. If pout3=pout0, that is, the actual output power is equal to the target power, the power adjustment is stopped.
It can be understood that the actual output power is repeatedly measured, and the VCC value is always kept unchanged, and is always equal to the VCC value corresponding to the target power Pout obtained by the calibration of the electronic device, until Pout (actual) =pout0, that is, the actual output power is equal to the target power, and the power adjustment is stopped.
In the embodiment of the application, the electronic device determines a corresponding Automatic Gain Control (AGC) value and a voltage VCC value according to a target power and a preset mapping relation table, wherein the target power is sent by the network device; the electronic equipment is powered according to the VCC value; when the electronic equipment detects and inputs the AGC value, the electronic equipment outputs a first actual output power currently; under the condition that the first actual output power is not equal to the target power, the electronic equipment adjusts the AGC value, keeps the VCC value unchanged, and obtains an adjusted first AGC value; when the electronic equipment detects and inputs the adjusted first AGC value, second actual output power which is currently output; and stopping power adjustment by the electronic equipment under the condition that the second actual output power is equal to the target power. The method and the device solve the problems that in the traditional power adjustment process, AGC always corresponds to VCC obtained through calibration one by one, and ACLR does not meet standard requirements or power consumption of the PA is high due to the fact that actual output power of the final power adjustment finished PA is different from the required VCC. The implementation mode of the method is simple, only the VCC value which corresponds to the target power Pout in the calibration table is required to be always kept in the power adjustment process of the electronic equipment, so that the requirement can be met by the index of the PA when the final power adjustment of the electronic equipment is finished due to the difference of the temperature and the like of the signaling environment, and the power consumption is not higher.
