Description
Technical Field
The present disclosure relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for switching a power amplifier mode.
Background
A terminal device (e.g., a cellular phone, etc.) having a wireless communication function includes a Power Amplifier (PA) to provide a higher transmission power for an output Radio Frequency (RF) signal. The power amplifier amplifies the radio frequency signal to a desired level for transmission.
When the power amplifier operates at maximum output power, its efficiency is highest, which can reach 50%. However, modulation signals with higher and higher Peak-to-average ratio (PAPR) are generally used in the current mainstream mobile communication standard, and since the amplitude response of the power amplifier becomes highly nonlinear in a compression region, the output power cannot reach the Peak value because of the higher PAPR, so that the power amplifier operates at an average output power far lower than the optimal power value, and the efficiency is reduced.

Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
In the present disclosure, unless expressly stated or limited otherwise, the terms "connected" and "connected" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection, or an integral part; can be mechanically connected, electrically connected or can communicate with each other; they may be directly connected or indirectly connected through intervening media, or may be connected through the interconnection of two elements or through the interaction of two elements. The specific meaning of the above terms in the present disclosure can be understood by those of ordinary skill in the art as appropriate.
In order to improve the efficiency of the power amplifier and achieve the purpose of saving the electric energy of the terminal device, an Envelope Tracking (ET) mode can be used, the power supply voltage of the power amplifier is dynamically adjusted based on the input signal level power of the power amplifier, and the corresponding relation between the instantaneous output power mapping and the optimized power supply voltage value is found out, so that the power amplifier is in a compression critical area as long as possible.
Another mode is the Average Power Tracking (APT) mode. In APT mode, the supply voltage of the power amplifier is adjusted on a per transmission slot basis. Therefore, in the ET mode, the power supply voltage of the power amplifier varies continuously with the input signal level power; while in APT mode the supply voltage of the power amplifier is constant during each time slot.
In the related art, in order to ensure the overall performance of the power amplifier and the power consumption of the terminal device, the ET mode is generally adopted when the output power of the power amplifier is large, and the APT mode is adopted when the output power is small. Whether to use ET mode or APT mode is determined by comparing the output power of the power amplifier to a fixed switching point threshold. The switching point threshold value is fixedly written into the memory of the terminal device. For example, the threshold is 17dbm when the output power of the power amplifier is rising, and 14dbm when the output power of the power amplifier is falling.
In this scheme, the above-described switching point threshold is employed regardless of the terminal device itself. Before the terminal device leaves the factory, once the threshold is written into the terminal device, the terminal device needs to perform mode switching by using the threshold. Because the threshold may not be suitable for some terminal devices, if the threshold is set too high, the power amplifier still cannot enter the ET mode when the power amplifier should be switched, and the efficiency of the power amplifier is reduced; and if the threshold is set too low, the power amplifier may enter ET mode too early, and power consumption is large.
Therefore, the embodiments of the present disclosure provide a method, an apparatus, a device, and a storage medium for switching a power amplifier mode, which can reduce power consumption of the power amplifier and improve endurance of a terminal device.
Hereinafter, the steps of the method for switching the power amplifier mode in the exemplary embodiment of the disclosure will be described in more detail with reference to the drawings and the embodiment.
Fig. 1 is a flow chart illustrating a method for power amplifier mode switching according to an example embodiment. The method provided by the embodiment of the disclosure can be executed by any terminal equipment with computing processing capability and wireless communication capability.
It should be understood that the term "terminal device" may refer to any terminal device that may access a wireless communication network and receive services therefrom. The terminal Equipment may include User Equipment (UE), which is also referred to as a mobile terminal or mobile User Equipment, etc. The user equipment may be a mobile terminal such as a mobile phone (also called a cellular phone) or a computer with a mobile terminal such as a portable, handheld or vehicle mounted mobile device or a mobile terminal device with a built-in computer.
The wireless communication network may be, for example, global system for mobile communications (GSM), General Packet Radio Service (GPRS), Wideband Code Division Multiple Access (WCDMA), High Speed Packet Access (HSPA), long term evolution network (LTE), LTE-advanced (LTE-a), New Radio (NR), WIFI, internet of things, etc. Further, the terminal devices may communicate with the network devices in the wireless communication network according to any suitable generation communication protocol, including but not limited to, first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G) communication protocols and/or any other protocol currently known or developed in the future.
Referring to fig. 1, a method 10 for power amplifier mode switching includes:
in step S102, the detected feedback current at the output terminal of the power amplifier and the current input signal power and output signal power of the power amplifier are obtained.
For example, a current detection device may be provided at the output of the power amplifier to detect the feedback current at the output of the power amplifier.
After the feedback current, the input signal power and the output signal power are detected, they may be sent to a processor in the terminal device (e.g., a baseband processor, or an application processor of the terminal device).
In step S104, the mode switching threshold corresponding to the feedback current, the input signal power and the output signal power is queried based on the preset corresponding relationship between the feedback current, the input signal power and the output signal power and the mode switching threshold.
Wherein the power amplifier switches modes based on a mode switch threshold.
The correspondence may be, for example, in the form of a table in which a plurality of sets of correspondences between feedback currents, input signal powers, output signal powers, and mode switching thresholds are stored. The corresponding relationship may be generated by test data obtained by performing a communication test on a large number of terminal devices and network devices, or may be generated by simulation data obtained by simulating communication between terminal devices and network devices in a cellular network, or may be generated based on a specific algorithm.
It should be noted that the determined mode switching threshold may be a set of values, for example, two values, one value is used for the power amplifier during the output power rising phase, and the other value is used for the power amplifier during the output power falling phase.
The method for switching the power amplifier mode provided by the embodiment of the present disclosure needs to be determined based on the actual input and output parameters (such as the fed-back output current, the output signal power and the input signal power) of the power amplifier when determining the mode switching threshold of the amplifier, rather than a fixed value which is the same for all terminal devices. By the method, the optimal mode switching point can be selected, so that the power consumption of the power amplifier and the power consumption of the terminal equipment are greatly reduced, the electric energy of the terminal equipment is saved, and the cruising ability of the terminal equipment is improved.

in step S202, the queried mode switching threshold is stored in the terminal device.
In the embodiment of the present disclosure, the steps S102 and S104 are executed, for example, in a factory test stage of the terminal device, and after the mode switching threshold is determined, the mode switching threshold is stored in the terminal device (for example, in a memory thereof). And after the terminal equipment leaves the factory subsequently, the mode switching threshold is used for carrying out the mode switching of the power amplifier.
In other embodiments, the preset correspondence between the feedback current, the input signal power, the output signal power, and the mode switching threshold may also be stored in the terminal device (e.g., in a memory thereof). After the terminal device leaves the factory, the operations in the steps S102 and S104 may be performed in real time or periodically, and the mode switching threshold is continuously adjusted in actual use, so as to determine a more optimal power switching point of the power amplifier, further reduce the power consumption of the power amplifier, and improve the cruising ability of the terminal device.
Fig. 3 is a flow chart illustrating yet another method for power amplifier mode switching in accordance with an exemplary embodiment. Unlike the method 10 for power amplifier mode switching shown in fig. 1, the method 30 shown in fig. 3 may further include, before step S102:
in step S302, the detected current temperature of the terminal device is acquired.
In step S304, based on the current temperature, the corresponding relationship between the corresponding feedback current, input signal power, and output signal power and the mode switching threshold is selected.
In the embodiment of the present disclosure, the preset corresponding relationship may include multiple types (for example, may be implemented as multiple corresponding relationship tables), and each corresponding relationship may correspond to a different temperature. The terminal equipment may have different temperatures due to the influence of the use environment and self-heating. At different temperatures, one correspondence table may not be applicable. Therefore, different correspondence relationships can be preset based on different temperatures. For example, a correspondence table may be preset for each of the three cases of high temperature, low temperature, and normal temperature. By this method the power switching point of the power amplifier is further optimized.
