Detailed Description
The present invention will be described in further detail with reference to examples.
For a terminal with 4G and 5G, the PA of 4G and the PA of 5G can only fix one Direct current conversion (rectification) chip; fig. 1 is a schematic diagram of a DCDC chip power supply method, and as shown in fig. 1, the power supply method includes two types:
one, the PA (4G PA) adopted by the 4G communication is supplied with power through a chip (DCDC _ APT) rectified based on an APT technology, and the 5G PA is supplied with power through a chip (DCDC _ ET) rectified based on an ET technology;
in another type, the 5G PA is powered by DCDC _ APT, and the 4G PA is powered by DCDC _ ET.
In the related art, the ET technology cannot meet the requirement of emission performance when the 5G PA works in a very large bandwidth (BW, Band width), for example, the bandwidth exceeds a certain bandwidth (for example, 100MHz), and the ET technology has limitation in the aspect of 5G application.
Based on this, in the embodiment of the present invention, a first bandwidth and a first power of a first communication module, and a second bandwidth and a second power of a second communication module are detected; the first communication module is associated with a first communication network, the second communication module is associated with a second communication network, and the first communication network is a next generation network of the second communication network; determining that the first bandwidth exceeds a first threshold, or determining that the first bandwidth is lower than the first threshold and the second power meets a first condition, and determining a first power supply mode; determining a second power supply mode when it is determined that the first bandwidth is lower than a first threshold and the first power satisfies a second condition;

Fig. 2 is a schematic flow chart of a power supply switching method according to an embodiment of the present invention; as shown in fig. 2, the power supply switching method is applied to a terminal, and the terminal supports a 4G technology and a 5G technology; the terminal can be a smart phone, a notebook computer, a Personal Digital Assistant (PDA), a tablet computer (PAD), a Portable Multimedia Player (PMP), etc.; the power supply switching method comprises the following steps:
wherein the first communication module is associated with a first communication network, the second communication module is associated with a second communication network, and the first communication network is a next generation network of the second communication network;

Specifically, the terminal supports both 4G technology and 5G technology. The first communication network may be a 5G network, and the second communication network may be a 4G network;
the first communication module can be a communication module supporting 5G network communication; the method specifically comprises the following steps: 5G PA;
the second communication module can be a communication module supporting 4G network communication; the method specifically comprises the following steps: 4G PA.
The first chip is related to APT and is characterized in that the first chip is powered by an APT DCDC chip (a chip powered by APT technology);
the second chip is related to ET, and the second chip is characterized by being powered by an ET DCDC chip (a chip powered by an ET technology).
That is, the first power supply mode includes: the 5G PA is powered by an APT DCDC chip, and the 4G PA is powered by an ET DCDC chip;
the second power supply mode includes: the 4G PA is powered by an APT DCDC chip, and the 5G PA is powered by an ET DCDC chip.
In one embodiment, the first threshold may be preset by a developer;
for example, considering that a 5G PA operates in a very large bandwidth, e.g., over 100MHz, ET technology cannot meet emission performance requirements; the first threshold may be set to 100 MHz. Of course, other values may be set, and are not limited herein.
By the method, whether the bandwidth changes or not can be detected in real time when the ET mode works under 5G, whether the bandwidth exceeds 100MHz or not is further judged when the bandwidth changes, and power supply is switched to APT DCDC power supply when the bandwidth exceeds 100MHz, namely the first power supply mode is selected, so that the most suitable power supply mode can be set according to the bandwidth.
In practical application, the real-time change of the power and the bandwidth of different communication modules is considered, so that the real-time detection is needed, and the switching of the power supply mode is carried out based on the detection result.
Based on this, in some embodiments, after the determining the first power mode, the method further comprises:

determining that the first power difference is greater than a first power threshold.
Specifically, the first power threshold may be preset and saved by a developer. For example, the first power threshold may be 3 dB.
Here, by setting the first power threshold, it is ensured that the switching of the power supply mode is performed after the power variation has a 3dB margin, so as to prevent the ping-pong effect.
In practical application, the real-time change of the power and the bandwidth of different communication modules is considered, so that the real-time detection is needed, and the switching of the power supply mode is carried out based on the detection result.
Based on this, in some embodiments, after the determining the second power supply mode, the method further comprises:

determining that the second power difference is greater than a second power threshold.
Specifically, the second power threshold may be preset and saved by a developer. For example, the first power threshold may be 3 dB.
Here, by setting the second power threshold, it is ensured that the switching of the power supply mode is performed after the power variation has a 3dB margin, so as to prevent the ping-pong effect.
In some embodiments, the second power satisfies a first condition comprising: the second power is greater than the first power;

the switching to the second power supply module includes: switching a first state of the switch to a second state;
the switching to the first power supply mode includes: and switching the second state of the selector switch to the first state.
The switching of the power supply mode is realized by switching the state of the selector switch.
In this case, the two DCDC chips cooperate with the external DPDT to realize the switching of the power supply mode, and the two DCDC chips operate independently without interference.
In practical application, the two DCDC chips can be cooperated to output power supply signals uniformly, and a switching mechanism is incorporated into the chip. For example, the APT DCDC chip multiplexes an ET chip internal switch direct current (Boost) circuit, the two DCDC chips supply power in two modes of APT and ET, and finally supply power to the two PAs through the output of the APT chip, and a switching mechanism is combined inside the APT chip. Therefore, the DPDT does not need to be set, and the space in the terminal is saved.
