[0043] The embodiments of the present application provide a method, a device, a radio frequency system, and a storage medium for selecting a power consumption mode channel, which are used to transmit the transmission signal of a transceiver by avoiding the current consumption of a power amplifier when the current power demand is less than a first power threshold, thereby reducing the power consumption of the transmission signal.

[0044] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All embodiments based on the embodiments of the present application should fall within the scope of protection of the present application.

[0045] With the development of communication networks, terminal devices have evolved from the initial 2G networks that only supported voice calls to the current 5G networks that support high-speed data traffic. Mobile communication is providing convenience for people's daily lives. However, the subsequent problem is that as the number of communication network standards increases, terminal devices must support the communication requirements under various network standards such as 2G, 3G, 4G, and 5G. Limited by the size constraints of terminal devices, the space of the main board (Printed Circuit Board, PCB) has not increased significantly due to the increasing demand, which will lead to a very tight layout and wiring of the main board PCB.

[0046] In order to meet the increasing demands of various network standards and at the same time address the problem of tight PCB layout, the high integration and miniaturization of devices have become an obvious development trend. From the initial second-generation integrated product (Phase2) that only supported single band to the seventh-generation integrated product (Phase7) that supports the integration of various standards, the integration degree of devices is getting higher and higher, and at the same time, the package size of devices is getting smaller and smaller.

[0047] Figure 1A is the application solution block diagram of 2 / 3 / 4 / 5G composed of Phase7 devices; Figure 1B is the application solution block diagram of 2 / 3 / 4 / 5G composed of Phase7lite devices; Figure 1C is the application solution block diagram of 2 / 3 / 4 / 5G composed of enhanced seventh-generation integrated product (Phase7lite Enhancement, Phase7LE) devices. Phase7lite is an upgraded product based on Phase7. Comparative analysis Figure 1A and Figure 1BIt can be seen that the main feature of Phase7lite is that, on the premise of keeping the package size of the original Phase7 device unchanged, the external Enhance Low Noise Amplifier (eLNA) part is integrated into the Power Amplifier (PA) Mid device, becoming a Low Power Amplifier Mid (L-PA Mid) device with an internal Low Noise Amplifier (LNA), so as to achieve the purpose of high device integration and device miniaturization. In addition, an intelligent switching switch is built into the Middle High Band (MHB); Phase7 LE further integrates more 5G functions on the basis of Phase7 lite (for example, MHB supports the n41 dual-transmission function, and the Low Band (LB) supports the built-in intelligent switching switch).

[0048] The following is a brief description of the radio frequency system:

[0049] As Figure 1D shown, it is a schematic diagram of a classic radio frequency system. The front-end system around the transceiver includes PA, duplexer, transmit filter (such as transport surface acoustic wave (TXSAW)), receive filter (such as receive surface acoustic wave (RXSAW)), switch and LNA devices. Among them, for the Time-division Duplex (TDD) system, the transmitted signal goes from the PA, through the transmit filter, to the switch and then to the antenna for output, and the received signal goes from the antenna, through the receive filter, to the LNA and then back to the transceiver; for the Frequency-division Duplex (FDD) system, the transmitted signal goes from the PA, through the transmit end of the duplexer, to the common end for output and then through the switch for output, and the received signal goes from the antenna, through the common end of the duplexer, to the receive end of the duplexer for output to the LNA and finally back to the transceiver.

[0050] As Figure 1EAs shown, it is a schematic diagram of the framework composition of a current typical integrated radio frequency system. The power consumption composition can also be mainly disassembled according to these modules. First is the baseband and the modem, where the baseband refers to the Central Processing Unit (CPU) module, and the modem is the modulation and demodulation related to communication; further forward is the transceiver, which mainly refers to analog modulation, frequency locking, etc. in the system, and further forward is the transmit and receive module of the system. The transmit and receive of the main set includes PA, LNA, and the control module, and the diversity receive module is mainly the internal control and LNA. Disassembling the power consumption of the entire radio frequency system and then focusing on one of the modules, for the full-link radio frequency system, the core power consumption is in the transmit part, and the main power consumption source of transmission is the PA.

[0051] As shown in Table 1, it is an example of the power consumption disassembly of a transmit link in an FDD frequency band at different power levels; as shown in Table 2, it is an example of the power consumption disassembly of a transmit link in a TDD frequency band at different power levels. It can be seen from the data in the table that, for example, in the transmit link of the B41 / n41 frequency band, the power consumption of the PA is mainly related to the power level and can be clearly divided into several stages. In the low-power mode (-9 - 5 dBm), the difference between the current and the power is not significant. In the medium-power mode (5 - 15 dBm), the difference between the current and the power is relatively small (about 20 - 30 mA). In the high-power mode (above 18 dBm), the difference between the current and the power gradually becomes larger. The power output of the radio frequency system mainly includes two parts: the output of the transmit signal by the transceiver itself (with a certain intensity), and then the output after being amplified by the PA. The main influencing factors for the result (intensity) of the transmit signal output are the gain of the transceiver and the gain of the PA.

[0052] PA gain refers to the gain of the power amplifier, usually expressed in decibels (dB). It represents the ratio of the power of the output signal to the power of the input signal. For example, if the gain of a PA is 10 dB, then its output power will be 10 times the input power.

[0053] Table 1 Proportion of Transmit Path Power Consumption in FDD Frequency Band at Different Power Levels

[0054]

[0055] Table 2 Proportion of Transmit Path Power Consumption in TDD Frequency Band at Different Power Levels

[0056]

[0057] Under the existing solution, it can be concluded from Table 1 and Table 2 that the PA inside the transmitting and receiving module accounts for more than 50% of the power consumption. The higher the power mode, the greater the transmitting current of its PA. In the low-power mode, for the increase in power, the increase in the PA current is not obvious, or even hardly increases (for example, below 5 dBm). That is to say, in this stage, the actual PA does not need to amplify the signal additionally for the increase in power (the output signal of the transceiver can already meet the signal power requirements).

[0058] From the perspective of the prior art, the output Pout of the entire radio frequency system can be simplified as Pin * Gain (gain). Among them, the Pin signal is equal to the output signal of the transceiver, and the output signal of the transceiver is equal to the product of its internal gain and the modulated signal. For a PA, its internal amplifier can be distinguished by different modes, generally LPM (low gain, Low Power Mode), MPM (medium gain), and HPM (high gain) modes. The gains Gain in these three modes are different. Finally, the transmitted signal intensity Pout of the radio frequency system = Pin * Gain, where Gain is switched according to different gain levels, and the Pin signal can also be selected according to the amplifier inside the transceiver. However, for the transmitted signal of the transceiver (generally can also reach within 5 dBm), its own gain does not need to be selected additionally, only minor adjustment is required, and the power consumption change involved is not large. However, in some small signal intensity modes of the current technical solution, the gain of the PA is actually still called for amplification to ensure the signal intensity. For example, when Pout needs to output 5 dBm, at this time the transceiver already has this ability, but the PA still needs to adjust a gain to meet the output (actually no amplification is required), but the call of the gain will definitely involve power consumption, which leads to additional power consumption of the PA at some current power levels.

[0059] The technical solution of the present application will be further described below by way of embodiments, as Figure 2 shown, is a schematic diagram of an embodiment of the method for selecting a power consumption mode channel in an embodiment of the present application. This method is applied to a radio frequency system, as Figure 3A shown, is a schematic diagram of an embodiment of a radio frequency system in an embodiment of the present application. The radio frequency system may include: a transceiver, a power amplifier, and an antenna; the transceiver is connected to the power amplifier, the power amplifier is connected to the antenna, and the transceiver is connected to the antenna. The method embodiment may include:

[0060] 201. Obtain the current power requirement of the transmitted signal of the transceiver.

[0061] Optionally, obtaining the current power requirement of the transceiver's transmitted signal may include: obtaining the current signal strength requirement of the transceiver's transmitted signal; obtaining the current power requirement according to the current signal strength requirement, where the current signal strength is negatively correlated with the current power.

[0062] 202. When the current power requirement is less than the first power threshold, select the first power consumption mode channel to output the transmitted signal.

[0063] 203. When the current power requirement is greater than or equal to the first power threshold, select the second power consumption mode channel to output the transmitted signal.

[0064] Wherein, the first power consumption mode channel is the channel connecting the transceiver and the antenna; the second power consumption mode channel is the channel connecting the transceiver, the power amplifier and the antenna, and the power consumption of the first power consumption mode channel is less than that of the second power consumption mode channel.

[0065] In the embodiment of the present application, it is possible to determine whether the current power requirement is less than the first power threshold, and select the corresponding power consumption mode channel to output the transmitted signal. When the current power requirement is greater than or equal to the first power threshold, select the second power consumption mode channel to output the transmitted signal; when the current power requirement is less than the first power threshold, select the first power consumption mode channel to output the transmitted signal, that is, the transmitted signal of the transceiver is transmitted by avoiding the current consumption of the power amplifier, thereby reducing the power consumption of the transmitted signal.

[0066] Optionally, the method may further include: obtaining the current gain requirement according to the current power requirement, where the current power is positively correlated with the current gain;

[0067] The step of selecting the first power consumption mode channel to output the transmitted signal when the current power requirement is less than the first power threshold may include: when the current gain requirement is less than the gain threshold, select the first power consumption mode channel to output the transmitted signal;

[0068] The step of selecting the second power consumption mode channel to output the transmitted signal when the current power requirement is greater than or equal to the first power threshold may include: when the current gain requirement is greater than or equal to the gain threshold, select the second power consumption mode channel to output the transmitted signal.

[0069] In the embodiments of the present application, the current gain requirement can be obtained according to the current power requirement; it is determined whether the current gain requirement is less than the gain threshold, and the corresponding power consumption mode channel is selected to output the transmission signal. When the current gain requirement is greater than or equal to the gain threshold, the second power consumption mode channel is selected to output the transmission signal; when the current gain requirement is less than the gain threshold, the first power consumption mode channel is selected to output the transmission signal, that is, the transmission signal of the transceiver is transmitted by avoiding the current consumption of the power amplifier, thereby reducing the power consumption of the transmission signal.

[0070] Optionally, the method may further include: obtaining the current output power of the transceiver; when the current output power is greater than the second power threshold, the first power consumption mode channel is selected to output the transmission signal, and the second power threshold is greater than or equal to the first power threshold.

[0071] In the embodiments of the present application, the current output power of the transceiver can be obtained. If the current output power is greater than the second power threshold, it indicates that the current output power of the transceiver is relatively high itself. If the user's current power requirement is less than the current output power, then the user's requirement can already be met and there is no need to amplify the power through the power amplifier. Therefore, the first power consumption mode channel can be selected to output the transmission signal.

[0072] Optionally, in some implementation manners of the present application, the radio frequency system further includes: a first-stage switch; the power amplifier is connected to the antenna through the first-stage switch; the transceiver is connected to the first-stage switch;

[0073] Implementation manner 1: The first power consumption mode channel is the channel through which the transceiver, the first-stage switch, and the antenna are connected; the second power consumption mode channel is the channel through which the transceiver, the power amplifier, the first-stage switch, and the antenna are connected. As Figure 3B shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiments of the present application.

[0074] Implementation manner 2: The first power consumption mode channel is the channel through which the transceiver and the antenna are connected; the second power consumption mode channel is the channel through which the transceiver, the power amplifier, the first-stage switch, and the antenna are connected. As Figure 3C shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiments of the present application.

[0075] In the embodiments of the present application, the function of the first-stage switch is to select a frequency band. In the first power consumption mode channel, the transmitted signal of the transceiver can be frequency band selected and then transmitted using the antenna; in the second power consumption mode channel, the transmitted signal after passing through the power amplifier can be frequency band selected and then transmitted using the antenna. Since the transmitted signal in the first power consumption mode channel has not been processed by the PA, and the transmitted signal in the second power consumption mode channel has been processed by the PA, the power consumption of the first power consumption mode channel is relatively smaller than that of the second power consumption mode channel.

[0076] Optionally, in some implementation manners of the present application, the radio frequency system further includes: a transmit filter and a duplexer; the first-stage switch is respectively connected to the transmit filter and the duplexer, and the transmit filter and the duplexer are connected to the antenna;

[0077] Implementation manner 1: The first power consumption mode channel is the channel connecting the transceiver, the first-stage switch, the transmit filter and the antenna, or the channel connecting the transceiver, the first-stage switch, the duplexer and the antenna; the second power consumption mode channel is the channel connecting the transceiver, the power amplifier, the first-stage switch, the filter and the antenna, or the channel connecting the transceiver, the power amplifier, the first-stage switch, the duplexer and the antenna. As Figure 3D shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiments of the present application.

[0078] Implementation manner 2: The first power consumption mode channel is the channel connecting the transceiver and the antenna; the second power consumption mode channel is the channel connecting the transceiver, the power amplifier, the first-stage switch, the filter and the antenna, or the channel connecting the transceiver, the power amplifier, the first-stage switch, the duplexer and the antenna. As Figure 3E shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiments of the present application.

[0079] In the embodiment of the present application, the radio frequency system may further include: a transmit filter and a duplexer; the duplexer is a main component of a heterodyne duplex radio and a repeater, and its function is to isolate the transmit and receive signals to ensure that both receive and transmit can work properly simultaneously. It consists of two groups of band-pass filters with different frequencies to prevent the transmit signal of the device from being transmitted to the receiver. The filter can effectively filter out specific frequency points in the power line or frequencies outside that frequency point to obtain a power signal with a specific frequency or a power signal after eliminating a specific frequency. In the first power consumption mode channel, after selecting the frequency band of the transmit signal of the transceiver, filtering processing can also be performed. Specifically, a transmit filter or a duplexer can be selected, and then the antenna is used for transmission; in the second power consumption mode channel, after selecting the frequency band of the transmit signal after the power amplifier, filtering processing can also be performed. Specifically, a transmit filter or a duplexer can be selected, and then the antenna is used for transmission. Since the transmit signal in the first power consumption mode channel has not undergone processing such as PA and filtering, and the transmit signal in the second power consumption mode channel has undergone processing such as PA and filtering, the power consumption of the first power consumption mode channel is relatively smaller than that of the second power consumption mode channel.

[0080] Optionally, the types of filters may include but are not limited to: low-pass filter, high-pass filter, band-pass filter, band-stop filter, notch filter, passive filter, active filter, digital filter.

[0081] Low-pass filter: Allows low-frequency signals to pass through while blocking high-frequency signals.

[0082] High-pass filter: Allows high-frequency signals to pass through while blocking low-frequency signals.

[0083] Band-pass filter: Only allows frequency signals within a certain range to pass through while blocking other frequency signals.

[0084] Band-stop filter: Blocks frequency signals within a certain range while allowing other frequency signals to pass through.

[0085] Notch filter: Used to eliminate interference signals of specific frequencies, usually used to eliminate noise or interference of specific frequencies.

[0086] Passive filter: Composed of passive components (such as resistors, capacitors, and inductors), it does not require an external power supply. For example, Resistor-Capacitance (RC) filters and inductance-Capacitance (LC) filters.

[0087] Active filter: Uses active components (such as operational amplifiers) to enhance the performance and gain of the filter.

[0088] Digital filter: A filter implemented through digital signal processing algorithms, used for digital signal processing and real-time control applications.

[0089] Optionally, in some implementation manners of the present application, the radio frequency system further includes: a second-stage switch; the transmit filter and the duplexer are connected to the second-stage switch, the second-stage switch is connected to the antenna; the transceiver is connected to the second-stage switch;

[0090] Implementation manner 1: The first power consumption mode channel is the channel connecting the transceiver, the first-stage switch, the transmit filter, the second-stage switch, and the antenna, or the channel connecting the transceiver, the first-stage switch, the duplexer, the second-stage switch, and the antenna; the second power consumption mode channel is the channel connecting the transceiver, the power amplifier, the first-stage switch, the filter, the second-stage switch, and the antenna, or the channel connecting the transceiver, the power amplifier, the first-stage switch, the duplexer, the second-stage switch, and the antenna. As Figure 3F shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiment of the present application.

[0091] Implementation manner 2: The first power consumption mode channel is the channel connecting the transceiver, the second-stage switch, and the antenna; the second power consumption mode channel is the channel connecting the transceiver, the power amplifier, the first-stage switch, the filter, the second-stage switch, and the antenna, or the channel connecting the transceiver, the power amplifier, the first-stage switch, the duplexer, the second-stage switch, and the antenna. As Figure 3G shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiment of the present application.

[0092] Implementation manner 3: The first power consumption mode channel is the channel connecting the transceiver and the antenna; the second power consumption mode channel is the channel connecting the transceiver, the power amplifier, the first-stage switch, the filter, the second-stage switch, and the antenna, or the channel connecting the transceiver, the power amplifier, the first-stage switch, the duplexer, the second-stage switch, and the antenna. As Figure 3HAs shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiment of the present application.

[0093] In the embodiment of the present application, the radio frequency system may further include a second-stage switch. The function of the second-stage switch is to select a frequency band. In the first power consumption mode channel, after the frequency band selection of the first-stage switch for the transmission signal of the transceiver, filtering processing can be performed. After the filtering processing, the frequency band selection of the second-stage switch can be performed, and then the antenna is used for transmission. Or, after the frequency band selection of the second-stage switch for the transmission signal of the transceiver, the antenna is used for transmission. Or, the transmission signal of the transceiver is directly transmitted using the antenna; in the second power consumption mode channel, after the frequency band selection of the first-stage switch for the transmission signal after passing through the power amplifier, filtering processing can be performed. After the filtering processing, the frequency band selection of the second-stage switch can be performed, and then the antenna is used for transmission. Because the transmission signal in the first power consumption mode channel has not undergone processing such as PA and filtering, and the transmission signal in the second power consumption mode channel has undergone processing such as PA and filtering, the power consumption of the first power consumption mode channel is relatively smaller than that of the second power consumption mode channel.

[0094] Optionally, in some implementation manners of the present application, the radio frequency system further includes at least one of a receive filter and a noise amplifier; when the radio frequency system includes the receive filter and the noise amplifier, the transceiver, the noise amplifier, the receive filter, and the second-stage switch are connected in sequence, and the noise amplifier is connected to the duplexer; as Figure 3I As shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiment of the present application. As Figure 3J As shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiment of the present application. As Figure 3K As shown, it is a schematic diagram of another embodiment of the radio frequency system in the embodiment of the present application.

[0095] The method may further include: the received signal received through the antenna passes through the second-stage switch, selects the receive filter or the duplexer, and is transmitted to the transceiver after passing through the noise amplifier.

[0096] In the embodiment of the present application, the radio frequency system may further include the receive filter and the noise amplifier. The noise amplifier may include a low-noise amplifier, a medium-noise amplifier, and a high-noise amplifier. The received signal received through the antenna passes through the second-stage switch, selects the receive filter or the duplexer, and is transmitted to the transceiver after passing through the noise amplifier, which increases the feasibility of the solution.

[0097] It should be noted that the radio frequency system applied in the embodiment of the present application includes but is not limited to the several examples disclosed in the present application, and other radio frequency systems including power amplifiers are within the protection scope of the present application.

[0098] The following takes the Figure 3I shown radio frequency system as an example for illustration. In the embodiment of the present application, the original LPM (PA) for the low-power mode is replaced with a bypass state, and the transmitted signal of the transceiver is directly output to ensure the signal strength requirement. A bypass switch is added between the transceiver and the PA and directly connected to the subsequent transmit filter or duplexer to meet the current signal strength requirement (outputting low power). The transmitted signal of the transceiver is directly used to be processed by the filter at the backend and then enter the switch and output to the antenna.

[0099] For the first power consumption mode channel, which can also be called the low-power mode channel, the transmitted signal output by the transceiver passes through the first-stage switch (skipping PA amplification) and respectively selects the transmit filter or duplexer for output. The transmitted signal passing through the transmit filter or duplexer is output through the second-stage switch. The transmitted signal after being selected by the second-stage switch is transmitted through the antenna.

[0100] For the second power consumption mode channel, which can also be called the normal power consumption mode channel, the transmitted signal output by the transceiver is amplified by the PA. The amplified transmitted signal passes through the first-stage switch and respectively selects the transmit filter or duplexer for output; the transmitted signal passing through the transmit filter or duplexer is output through the second-stage switch; the transmitted signal after being selected by the second-stage switch is transmitted through the antenna.

[0101] Exemplarily, the current power requirement of the terminal device is obtained through the power feedback at the front end. If the current power requirement is greater than or equal to the first power threshold, it enters the normal power consumption mode channel, that is, the PA of the radio frequency system is turned on and the normal gain is called; if the current power requirement is less than the first power threshold, it enters the low-power mode channel, that is, the transceiver directly outputs the transmitted signal. Or, the current power requirement of the terminal device is obtained through the power feedback at the front end and the current power requirement is converted into the current gain requirement. If the current gain requirement is greater than or equal to the gain threshold, it enters the normal power consumption mode channel, that is, the PA of the radio frequency system is turned on and the normal gain is called; if the current gain requirement is less than the gain threshold, it enters the low-power mode channel, that is, the transceiver directly outputs the transmitted signal. As Figure 4A shown, it is a schematic flow chart of selecting the power consumption mode channel based on the gain in the embodiment of the present application.

[0102] It can be understood that generally, the first power threshold and the gain threshold are empirical values, but they can also be adjusted according to the actual output power of the transceiver.

[0103] As shown in Table 3, the power consumption data of the TDD frequency band in two states of PA being turned on (ON) or off (OFF) are presented. When PA is on, it corresponds to the second power consumption mode channel, and when PA is off, it corresponds to the first power consumption mode channel. From the example data in Table 3, it can be seen that the overall current gain is 14 - 30 mA (by using the received signal strength to fully adopt the second power consumption mode channel when the whole machine output is below 0 dBm, and selecting an appropriate PA gain for switching).

[0104] Table 3

[0105]

[0106] In the embodiment of the present application, the first power consumption mode channel is the channel where the transmitted signal of the transceiver passes through the first-stage switch, selects the transmit filter or the duplexer, and after being processed by the second-stage switch, is transmitted using the antenna; the second power consumption mode channel is the channel where the transmitted signal of the transceiver passes through the PA and the first-stage switch, selects the transmit filter or the duplexer, and after being processed by the second-stage switch, is transmitted using the antenna. When the current power demand is less than the first power threshold, the transmitted signal of the transceiver is transmitted by avoiding the current consumption of the power amplifier, thereby reducing the power consumption of the transmitted signal. That is, a low-power mode channel is established to optimize the current through dynamic control.

[0107] The following takes Figure 3J the shown radio frequency system as an example for illustration. In the embodiment of the present application, when the output power of the transceiver is fixed, the performance of the transceiver can be maximized by further reducing the front-end loss. The core is to directly enter the second-stage switch by bypassing the intermediate first-stage switch, transmit filter, duplexer and other devices with the transmitted signal output by the transceiver, and finally output to the antenna.

[0108] The first power consumption mode channel, which can also be called the low-power mode channel, skips the PA, the first-stage switch, the transmit filter or the duplexer with the transmitted signal output by the transceiver, and directly outputs through the second-stage switch. The transmitted signal after being selected by the second-stage switch is transmitted through the antenna.

[0109] The second power consumption mode channel, which can also be called the normal power consumption mode channel, amplifies the transmitted signal output by the transceiver through the PA. The amplified transmitted signal passes through the first-stage switch to respectively select the transmit filter or the duplexer for output; the transmitted signal passing through the transmit filter or the duplexer is output through the second-stage switch again; the transmitted signal after being selected by the second-stage switch is transmitted through the antenna.

[0110] Exemplarily, the current power demand of the terminal device is obtained through power feedback at the front end. If the current power demand is greater than or equal to the first power threshold, it enters the normal power consumption mode channel, that is, the PA of the radio frequency system is turned on and the normal gain is called. If the current power demand is less than the first power threshold, it enters the low power consumption mode channel, that is, the transceiver directly outputs the transmission signal. Alternatively, the current power demand of the terminal device is obtained through power feedback at the front end, and the current power demand is converted into the current gain demand. If the current gain demand is greater than or equal to the gain threshold, it enters the normal power consumption mode channel, that is, the PA of the radio frequency system is turned on and the normal gain is called. If the current gain demand is less than the gain threshold, it enters the low power consumption mode channel, that is, the transceiver directly outputs the transmission signal.

[0111] As Figure 4B shown, it is a schematic diagram of the filter loss comparison of two cases of the first power consumption mode channel in the embodiment of the present application. Case 1 of the first power consumption mode channel is the power consumption of the transmission signal output from the transceiver skipping the PA, passing through the first-stage switch, filter, and second-stage switch, and then being transmitted through the antenna. Case 2 of the first power consumption mode channel is the power consumption of the transmission signal output from the transceiver directly passing through the second-stage switch and then being transmitted through the antenna. Figure 4B Taking the B41 frequency band as an example for illustration. The transmission signal output from the transceiver directly passes through the second-stage switch and then is transmitted through the antenna, which can eliminate the filter loss of B41. Assuming that the filter loss is about 1.5 dB, under the same conditions, the signal strength of the transmission signal directly output by the receiver passing through the second-stage switch can be increased by 1.5 dB.

[0112] Optionally, for Case 1 of the first power consumption mode channel (the transmission signal output from the transceiver skips the PA, passes through the first-stage switch, filter, and second-stage switch, and then is transmitted through the antenna), the corresponding power threshold or gain threshold is equal to or less than that of Case 2 (the transmission signal output from the transceiver directly passes through the second-stage switch and then is transmitted through the antenna).

[0113] Optionally, when the power threshold or gain threshold corresponding to Case 1 of the first power consumption mode channel is less than the power threshold or gain threshold corresponding to Case 2, the power threshold or gain threshold corresponding to Case 2 can be the power threshold or gain threshold corresponding to Case 1 plus the optimized power or gain of Case 2 relative to Case 1.

[0114] In an embodiment of the present application, the first power consumption mode channel is the channel through which the transmitted signal of the transceiver is processed by the second-stage switch and then transmitted using the antenna; the second power consumption mode channel is the channel through which the transmitted signal of the transceiver passes through the PA and the first-stage switch, selects the transmit filter or the duplexer, is processed by the second-stage switch, and then is transmitted using the antenna. When the current power demand is less than the first power threshold, the transmitted signal of the transceiver is transmitted by avoiding the current consumption of the power amplifier, the first-stage switch, and the filter, thereby further reducing the power consumption of the transmitted signal.
