Detailed Description
The technical solutions in the embodiments of the present application will be described below clearly with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
With the development of the fifth Generation mobile communication technology (abbreviated as 5G), in order to obtain higher communication bandwidth, the frequency range of the 5G NR band is developed to higher frequency and wider bandwidth, and the frequency range is as shown in table 1 (defined by the third Generation Partnership project (3 gpp) standard organization):
TABLE 1
Figure BDA0003189431370000031
Figure BDA0003189431370000041
Meanwhile, wiFi defines frequency bands as shown in table 2:
TABLE 2
Figure BDA0003189431370000042
As can be seen from tables 1 and 2, the harmonics of the NR signal of Frequency Division Duplexing (FDD) overlap with the 5G WiFi part Frequency, and thus there is a case where the harmonics of the NR signal interfere with the 5G WiFi. For example, the transmission frequency of the n1 band signal is 1920MHz to 1980MHz, the third harmonic frequency range thereof is 5760MHz to 5940MHz, and the third harmonic frequency range is just overlapped with the high channel of 5G WiFi, so that there is a problem that the harmonic of the n1 band signal interferes with the 5G WiFi.
An architecture diagram of WiFi and NR coexistence is shown in fig. 1, and an interference path between a WiFi transceiver and a main rf transceiver includes: (1) interference path 1: the harmonic waves of the main radio frequency path are radiated out through the ANT1 (antenna 1), received by the ANT2 (antenna 2) of the WiFi and enter the receiving path of the 5G WiFi, and therefore interference is generated on the 5G WiFi receiving signals. (2) interference path 2: harmonic waves generated by the main radio frequency NR radio frequency power amplifier are directly coupled to the WiFi receiving circuit through the NR PA body or the PA power supply, so that interference is generated on 5G WiFi receiving signals.
For the design of the main rf, in order to ensure endurance, the electronic device generally uses Power saving technologies such as an Average Power Tracking (APT) mode or an Envelope Tracking (ET) mode, so as to reduce Power consumption of the PA and prolong the service life of the battery.
As can be seen from fig. 2 and fig. 3, in the ET mode, the power supply voltage VCC varies with the envelope of the radio frequency signal, while in the APT mode, the power supply voltage VCC only adjusts the level of the power supply voltage according to the power of the radio frequency signal. It follows that ET mode is more power efficient than APT mode.
Meanwhile, the power supply of the PA is more jittered in the ET mode than in the APT mode, so that the harmonics generated by the PA in the ET mode are larger. At the same power, the ET mode and APT mode power consumption are compared, as shown in table 3:
TABLE 3
Figure BDA0003189431370000051
At the same power, the ET mode and APT mode produce a harmonic magnitude comparison, as shown in table 4:
TABLE 4
Figure BDA0003189431370000052
At the same power, the harmonics generated by the ET mode and the APT mode are compared with each other in terms of the interference level of the WiFi receiving signal, as shown in table 5:
TABLE 5
Figure BDA0003189431370000053
According to the embodiment of the application, the time division information transmitted and received by the WiFi signals is used for distinguishing the time division signals transmitted by the NR power supply mode through the WiFi in the scene of coexistence of the NR signals and the WiFi signals, so that a certain power saving effect is achieved, and meanwhile, the interference in the scene of coexistence can be reduced.
The power supply control method, the power supply control device, the electronic device, and the readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
An embodiment of the present application provides a power supply control method, as shown in fig. 4, the power supply control method includes:
step 402, under the condition that the first communication device and the second communication device work simultaneously and interference exists between a signal transmitted by the first communication device and a signal received by the second communication device, switching a power supply mode of a radio frequency power amplifier circuit corresponding to the first communication device according to whether the second communication device receives the signal; wherein the power supply mode comprises an envelope tracking mode and an average power tracking mode.
In this embodiment, in the case where the NR communication means (i.e., the first communication means) and the WiFi means (i.e., the second communication means) of the electronic apparatus operate simultaneously, i.e., the NR signal (i.e., the operation signal of the first communication means) and the WiFi signal (i.e., the reception signal of the second communication means) coexist, it is determined whether there is interference between the NR signal (i.e., the signal transmitted by the first communication means) and the WiFi signal (i.e., the signal received by the second communication means). If interference exists between the NR signal and the WiFi signal, for example, partial frequency of the harmonic wave of the NR signal is overlapped with that of the WiFi signal, the power supply mode of the radio frequency power amplifier circuit of the NR communication device is determined according to whether the second communication device receives the signal, namely the time division information of receiving the WiFi signal, so that the power supply mode of the radio frequency power amplifier circuit is switched between an ET mode and an APT mode.
Through the mode, the NR power supply mode can be distinguished through the time division signals transmitted by the WiFi under the condition that the NR signals and the WiFi signals coexist and have interference, the interference under the coexistence scene can be reduced, and meanwhile, a certain power saving effect is achieved.
In addition, it should be noted that, in the related art, there is a method for reducing the NR power to reduce the interference between signals, but this method may affect the coverage of NR transmission signals, and affect the user experience. By the embodiment of the application, interference between signals can be reduced, and meanwhile coverage of NR signals can not be affected.
Further, in an embodiment of the present application, switching a power supply mode of a radio frequency power amplifier circuit corresponding to a first communication device according to whether a second communication device performs signal reception includes: supplying power to the radio frequency power amplifier circuit according to an average power tracking mode when the second communication device is in a time period for receiving signals; and in the time period when the second communication device does not receive the signal, supplying power to the radio frequency power amplifier circuit according to the envelope tracking mode.
In this embodiment, whether the second communication device performs signal reception is controlled by a WiFi control signal of the second communication device. When the signal receiving time is in a signal receiving time period, in order to reduce the interference of the NR signal to the WiFi signal, power is supplied to the PA according to an APT mode; and when the time slot is in the time slot without signal reception, power is supplied to the PA according to the ET mode for achieving the purpose of saving more power.
In the related art, power is supplied only by the APT mode (as shown in fig. 5), or power is supplied only by the ET mode (as shown in fig. 6). In the embodiment of the present application, as shown in fig. 7, when a coexistence scene exists between an NR signal and a WiFi signal, a power supply of the NR signal is time-division controlled, and during a WiFi Reception (RX) period (in fig. 7, a WiFi _ control signal is between RX _ ON and RX _ OFF), the PA power supply is supplied with APT, so that the generation of harmonics is reduced, and thus the degradation of the WiFi RX reception performance is reduced; in the WiFi non-RX time period, namely the time that the RX receives interference is staggered, the ET is used for supplying power for the PA power supply, the power consumption of radio frequency signals is reduced, and the cruising ability of the electronic equipment is improved.
Further, in an embodiment of the present application, the power supply control method further includes: and under the condition that no interference exists between the signal transmitted by the first communication device and the signal received by the second communication device, supplying power to the radio frequency power amplifier circuit according to an envelope tracking mode.
In this embodiment, when it is determined that there is no interference between the NR signal and the WiFi signal, power is supplied to the PA in the ET mode, so that power consumption of the radio frequency signal is reduced, and cruising ability of the electronic device is improved.
In addition, it should be noted that, when the second communication device is not turned on, power is supplied to the radio frequency power amplifier circuit according to the envelope tracking mode.
In this embodiment, when the WiFi device is not turned on, that is, when the NR signal and the WiFi signal do not coexist, power is supplied to the PA in the ET mode, so that power consumption of the radio frequency signal is reduced, and endurance of the electronic device is improved.
Further, in an embodiment of the present application, the power supply control method further includes: comparing a combination of a signal transmitted by the first communication device and a signal received by the second communication device with a signal combination in a pre-stored preset signal list, wherein the signal combination in the preset signal list is a signal combination with interference; determining that interference exists between a signal transmitted by the first communication device and a signal received by the second communication device in the case where the combination exists in the preset signal list; in the absence of the combination in the preset signal list, it is determined that there is no interference between the signal transmitted by the first communication device and the signal received by the second communication device.
In this embodiment, a method of determining whether there is interference between an NR signal and a WiFi signal in the case where the NR signal coexists with the WiFi signal is defined. Specifically, in the development stage of the electronic device, a preset signal list is stored in the electronic device, and a signal combination of an NR signal and a WiFi signal that may generate interference in a coexistence situation, for example, n1 of NR or n3 of third harmonic interference 5G WiFi, is recorded in the preset signal list.
The current NR signal and WiFi signal are compared with signal combinations recorded in a preset signal list. Determining that there is interference between the current NR signal and the WiFi signal if a combination of the current NR signal and the WiFi signal exists in a preset signal list; if the combination of the current NR signal and the WiFi signal does not exist in the preset signal list, it is determined that there is no interference between the current NR signal and the WiFi signal.
By the method, whether interference exists between the current NR signal and the WiFi signal can be accurately and quickly determined.
In a specific embodiment of the present application, as shown in fig. 8, the power supply control method includes:
step 802, in a development stage, storing information such as signals with coexisting interference, the size of harmonic waves generated by a main radio frequency power supply mode (ET mode and APT mode), and the like into electronic equipment to form a preset signal list;
step 804, determining whether the WiFi device is turned on, if not, entering step 806, and if so, entering step 808;
step 806, the transmitting power amplifier of the nr device is powered using ET mode;
step 808, comparing the working signal and the WiFi signal of the NR device with a preset signal list;
step 810, determining whether the operating signal and the WiFi signal of the NR device are consistent with a preset signal list, if so, entering step 812, otherwise, entering step 806;
at step 812, the power mode of the transmit power amplifier of the nr device is switched between ET mode and APT mode.
In this embodiment, in the WiFi off state, the transmission power amplifier of the NR device enters the ET power supply mode. And when the combination does not exist in the preset signal list, the transmitting power amplifier of the NR device enters an ET power supply mode.
When the combination exists in the preset signal list, the transmission power amplifier of the NR device enters a power supply mode in which the ET mode and the APT mode are switched. Specifically, when a WiFi RX signal is turned on, a transmitting power amplifier of the NR device enters an APT power supply mode, and when WiFi is in a non-RX signal receiving time period, a power supply enters an ET mode for power supply, so that power saving is guaranteed, and interference can be reduced.
According to the embodiment of the application, the power supply of the NR transmitting power amplifier is controlled according to time division through the characteristic of WiFi time division signals. In the ET mode, NR harmonics are large, but power can be saved; in the APT mode, the NR harmonic is small, but the power consumption is higher than that in the ET mode. As shown in fig. 7, the power supply of the NR transmitting power amplifier is controlled by time division, when the WiFi signal is in a non-RX time period, the NR transmitting power amplifier is powered in an ET mode to achieve power saving effect, and when the WiFi receiving signal is turned on, the NR transmitting power amplifier is powered to an APT mode, so as to reduce the size of NR harmonic wave.
It should be noted that, in the power supply control method provided in the embodiment of the present application, the execution main body may be a power supply control device, or a control module in the power supply control device for executing the power supply control method. In the embodiment of the present application, a power supply control device executes a power supply control method as an example, and the power supply control device provided in the embodiment of the present application is described.
