Description

TECHNICAL FIELD

[0001] The disclosure relates to an apparatus and method of controlling a voltage conversion mode in an electronic device. BACKGROUND

[0002] An electronic device can include a voltage converter for stably supplying a predetermined level of voltage to internal circuitry. The voltage converter can include a direct current / direct current (DC-DC) converter that converts a direct current voltage provided by a battery or an external power source of an external device into a direct current voltage of a predetermined level (e.g., 5V) and outputs the converted direct current voltage. For example, the DC-DC converter can support a step-down conversion function of reducing a voltage of an input power source to a predetermined level or a step-up conversion function of increasing a voltage of an input power source to a predetermined level.

[0003] The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. SUMMARY

[0004] A direct current / direct current (DC-DC) converter can convert an input voltage into a voltage of a predetermined level by using a pulse frequency modulation (PFM) mode or a pulse width modulation (PWM) mode. The PFM mode has a relatively good voltage conversion efficiency, and thus is advantageous in terms of consumed current. However, a supply of a relatively high load current is limited, and noise can be relatively much generated. The PWM mode supports a higher load current, and noise is relatively less. However, the PWM mode has a relatively low conversion efficiency, and thus is disadvantageous in terms of consumed current.

[0005] In a case in which an electronic device configures a voltage conversion mode of a DC-DC converter as a PFM mode, noise generated by the DC-DC converter affects communication performance, and thus a transmission rate (throughput) can decrease. In a case in which the electronic device configures the voltage conversion mode of the DC-DC converter as a PWM mode, conversion efficiency is low, and thus consumed current can increase.

[0006] Various aspects of the disclosure are to address at least the above-mentioned problems and / or disadvantages, and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an apparatus and method for controlling a voltage conversion mode in order to improve communication efficiency while reducing current consumption of an electronic device.

[0009] According to another aspect of the disclosure, a method for operating an electronic device is provided. The method includes identifying a modulation order for communication with an external device in a case where communication with the external device is performed using a wireless resource, and configuring a voltage conversion mode of a power management module that supplies power to a communication processor included in the electronic device as a PFM mode or a PWM mode based on the modulation order.

[0035] Figure 1 is a block diagram illustrating an electronic device 101 in a network environment 100 according to various embodiments. Referring to FIG. 1, Figure 1The electronic device 101 in the network environment 100 can communicate with an electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or an electronic device 104 or a server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, the electronic device 101 can communicate with the electronic device 104 via the server 108.

According to an embodiment, the connection terminal 178 can include, for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector (e.g., a headphone connector).

[0047] The haptic module 179 can convert an electrical signal into a mechanical stimulus (e.g., a vibration or movement) or electrical stimulus that can be recognized by a user via his tactile sensation or kinesthetic sensation. According to an embodiment, the haptic module 179 can include, for example, a motor, a piezoelectric element, or an electrical stimuluser.

[0049] The power management module 188 can manage power supplied to the electronic device 101. According to an embodiment, the power management module 188 can be implemented as at least part of, for example, a power management integrated circuit (PMIC).

[0050] The battery 189 can supply power to at least one component of the electronic device 101. According to an embodiment, the battery 189 can include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell.

[0051] The communication module 190 can support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication between the established communication channel. The communication module 190 can include one or more communication processors that are operable independently from the processor 120 (e.g., an application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 can include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules can be implemented as a single component (e.g., a single chip) or can be implemented as separate components (e.g., separate chips) from each other. The wireless communication module 192 can identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

According to an embodiment, the antenna module 197 can include one or more antennas, and, accordingly, at least one antenna appropriate for a communication scheme used in a communication network, such as the first network 198 or the second network 199, can be selected and used by, for example, the communication module 190 (e.g., the wireless communication module 192). Then, the signal or the power can be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna.

[0053] At least some of the above-described components can be configured as one or more processors by, for example, operating system or application programs, such as the programs 130.

[0054] According to an embodiment, commands or data can be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199.

According to an embodiment, all or some of the operations to be executed by the electronic device 101 can be executed at one or more of the external electronic devices 102, 104, or server 108. For example, if the electronic device 101 is to automatically perform a function or a service or is to request a function or a service in response to a request from a user or another device, the electronic device 101, instead of or in addition to executing the function or the service, can request at least some of the function or the service to be executed by the one or more external electronic devices. The one or more external electronic devices receiving the request can execute at least some of the requested function or service, or perform other functions or other services related to the request, and transfer an outcome of the execution to the electronic device 101. The electronic device 101 can provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology can be used, for example.

[0065] Figure 6A and Figure 6B are constellation diagrams showing an interference impact in a case where a second modulation mode is used according to various embodiments of the disclosure.

[0066] Referring to Figure 2 , the electronic device 101 can include a processor 210, a communication processor 220, a wireless communication module 230, and a power management module 240. According to an embodiment of the disclosure, the processor 210 can be the same as or can be included in the main processor 121 of Figure 1 . The communication processor (CP) 220 can be the same as or can be included in the communication processor 120 of Figure 1the same as or can be included in the auxiliary processor 122. The wireless communication module 230 can communicate with Figure 1 the same as or can be included in the wireless communication module 192. The power management module 240 can communicate with Figure 1 the same as or can be included in the power management module 188.

[0067] According to various embodiments of the present disclosure, the processor 210 can control a voltage conversion mode of the power management module 240. For example, the voltage conversion mode of the power management module 240 can include a mode for converting a voltage to be supplied to an internal circuit (e.g., the communication processor 220) of the electronic device 101 to a designated level.

[0068] According to an embodiment of the present disclosure, the processor 210 can configure a voltage conversion mode of the DC-DC conversion module 242 for supplying power to an internal circuit (e.g., the communication processor 220) of the electronic device 101 based on a load current related to a power supply of the electronic device 101. As an example, the voltage conversion mode can include at least one of a pulse frequency modulation (PFM) mode or a pulse width modulation (PWM) mode.

[0069] According to an embodiment of the present disclosure, in a case where the processor 210 performs wireless communication with an external electronic device through the wireless communication module 230, the voltage conversion mode of the DC-DC conversion module 242 for supplying power to an internal circuit (e.g., the communication processor 220) of the electronic device 101 can be configured based on a modulation order of the wireless communication. For example, as Figure 3 indicated in FIG. 3, a voltage conversion efficiency of the PFM mode 300 can be maintained to be relatively greater than a voltage conversion efficiency of the PWM mode 310. The PFM mode 300 can maintain a higher voltage conversion efficiency at a relatively lower load current than the PWM mode 310. As an example, in Figure 3 , a horizontal axis can indicate a load current and a vertical axis can indicate a voltage conversion efficiency according to the load current. For example, in a case where a frequency (e.g., 2.4 MHz) changed by the PFM mode is assumed to be adjacent to a baseband in the DC-DC conversion module 242, a power spectral density of a received signal can be as Figure 4 indicated in FIG. 4. Figure 4 shows a characteristic in which an interference signal generated by the PFM mode is introduced into a baseband in an environment in which an Eb / No (energy per bit / noise power spectral density) is 40 dB, in which a horizontal axis can indicate a frequency band and a vertical axis can indicate a power level with respect to a frequency. For example, as Figure 4As shown, the power based on the PFM mode conversion of the DC-DC conversion module 242 can include a peak 420 in a 2.4 MHz band (e.g., the power spectral density 400 before passing through a filter (e.g., a band pass filter) and the power spectral density 410 after filtering using the filter). In this case, the peak 420 in the 2.4 MHz band can affect the interference of the baseband signal. As an example, the modulation mode corresponding to the modulation order can be affected by the interference, as shown in Table 1 below. For example, Table 1 can indicate the symbol error rate (SER) of each modulation mode according to whether there is interference or not.

[0070] Table 1

[0071] Modulation order No interference With interference 16QAM 0.0％ 0.0％ 32QAM 0.0％ 0.0％ 64QAM 0.0％ 2.0％ 128QAM 0.0％ 26.1％ 256QAM 2.0％ 73.6％

[0072] As shown in Table 1, the modulation modes from 16 quadrature amplitude modulation (QAM) to 64 QAM are not affected by the interference or are relatively less affected by the interference, and thus the SER can be maintained regardless of whether there is interference or not. As shown in Table 1, the SER can be rapidly deteriorated due to the interference from the modulation order of 128 QAM. For example, in the case of the modulation mode of 128 QAM not affected by the interference, as shown in Figure 5A , the received signals are gathered in the constellation diagram according to the modulation mode. However, in the case of the modulation mode of 128 QAM affected by the interference, as shown in Figure 5B , the received signals are not gathered in the constellation diagram according to the modulation mode, and thus the effect of the interference on the symbol can be increased. As another example, in the case of the modulation mode of 256 QAM not affected by the interference, as shown in Figure 6A , the received signals are gathered in the constellation diagram according to the modulation mode. However, in the case of the modulation mode of 256 QAM affected by the interference, as shown in Figure 6B , the received signals are not gathered in the constellation diagram according to the modulation mode, and thus the effect of the interference on the symbol can be increased. Accordingly, in the case of using the modulation mode less affected by the interference, the processor 210 can configure the PFM mode as the voltage conversion mode of the DC-DC conversion module 242 to reduce the power consumption. In the case of using the modulation mode affected by the interference, the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 as the PWM mode to maintain the transmission rate of the wireless communication. As an example, the modulation order can include an index for indicating each modulation mode. As an example, the modulation order can be identified based on at least one of a channel quality indicator (CQI) index, a modulation and coding scheme (MCS) index, or MCS table information. As an example, Figure 5A-5B , and Figure 6A-6B each of which indicates a constellation of the received signal corresponding to the modulation mode, in which a horizontal axis can indicate an in-phase amplitude and a vertical axis can indicate a quadrature amplitude.

[0073] According to an embodiment of the disclosure, in a case where the processor 210 performs wireless communication with an external electronic device through the wireless communication module 230, a voltage conversion mode of a DC-DC conversion module 242 for supplying power to internal circuits (e.g., the communication processor 220) of the electronic device 101 can be configured based on a signal-to-interference-plus-noise ratio (L1-SINR) of a physical layer. As an example, the L1-SINR can include channel state information (e.g., interference) identified by receiving at least one of a synchronization signal / physical broadcast channel (SS / PBCH) block (SSB), a non-zero power channel state information reference signal (NZP-CSI-RS), or a zero power CSI-RS (ZP-CSI-RS). The L1-SINR can be calculated by a signal part (e.g., SSB or NZP-CSI-RS) and an interference part (e.g., at least one of a dedicated ZP-CSI-RS or NZP-CSI-RS) of a reference signal designated by a base station. The reference signal designated by the base station can be used for reporting an SS / PBCH resource block indicator / CRS-RS resource indicator (SSBRI / CRI). The number of SSBRI / CRI is one to at most four.

[0074] According to an embodiment of the disclosure, in a case where the processor 210 performs wireless communication with an external electronic device through the wireless communication module 230, a voltage conversion mode of a DC-DC conversion module 242 for supplying power to internal circuits (e.g., the communication processor 220) of the electronic device 101 can be configured based on whether ultra-reliable low latency communication (URLLC) is configured.

[0075] According to an embodiment of the disclosure, in a case where the processor 210 maintains an RRC connection with an external electronic device (e.g., a base station) through the wireless communication module 230, the processor 210 can configure a voltage conversion mode of a DC-DC conversion module 242 for supplying power to internal circuits (e.g., the communication processor 220) of the electronic device 101 based on discontinuous reception (DRX) state information.

[0077] According to various embodiments of the present disclosure, the processor 210 can adaptively configure a reference related to a change in the voltage conversion mode to prevent frequent changes in the voltage conversion mode. According to an embodiment of the present disclosure, in the processor 210, the reference when the first voltage conversion mode (e.g., the PFM mode) is changed to the second voltage conversion mode (e.g., the PWM mode) and the reference when the second voltage conversion mode is changed to the first voltage conversion mode can be differently configured. According to another embodiment of the present disclosure, the processor 210 can perform control to maintain the voltage conversion mode for a reference time in the case where the voltage conversion mode is changed.

[0078] According to various embodiments of the present disclosure, the communication processor 220 can control the wireless communication module 230 to transmit or receive a signal to or from an external electronic device through at least one network.

[0079] According to various embodiments of the present disclosure, the wireless communication module 230 can transmit or receive a signal to or from an external electronic device through at least one network. As an example, the wireless communication module 230 can include a radio frequency integrated circuit (RFIC) and a radio frequency front end (RFFE). The RFIC can convert a baseband signal provided by the communication processor 220 into a radio signal, or can convert a radio signal provided by the RFFE into a baseband signal. The RFFE can include processing for receiving or transmitting a signal through an antenna. For example, the RFFE can include an element for amplifying power of a signal or an element for removing noise.

[0080] According to various embodiments of the present disclosure, the power management module 240 can control power supplied from a battery or an external power source to be supplied to internal circuits (e.g., internal elements) of the electronic device 101. According to an embodiment of the present disclosure, the power management module 240 can stably provide a predetermined level of voltage to the internal circuits (e.g., the communication processor 220) of the electronic device 101 through the DC-DC conversion module 242.

[0081] According to various embodiments of this disclosure, the DC-DC conversion module 242 can convert voltage to PFM or PWM mode and supply the voltage to the internal circuitry of the electronic device 101 (e.g., communication processor 220). According to embodiments of this disclosure, when the processor 210 determines a change in the voltage conversion mode, the DC-DC conversion module 242 can change the voltage conversion mode at the point in time when the change is determined. According to embodiments of this disclosure, when the processor 210 determines a change in the voltage conversion mode, the DC-DC conversion module 242 can change the voltage conversion mode at a point in time when no data transmission / reception via wireless resources occurs (e.g., idle state). As an example, the DC-DC conversion module 242 can be included in or separately from the power management module 240.

[0082] According to various embodiments of this disclosure, when providing 5G (e.g., New Radio (NR)) communication services, processor 210 can change the voltage transition mode (LTE) network by utilizing Long Term Evolution (LTE).

Processor 210 can change the voltage transition mode when resetting the 5G network core. Processor 210 can access the 5G network when a restart of electronic device 101 based on the voltage transition mode change is completed.

[0087] According to various embodiments of the present disclosure, the at least one processor can configure the voltage conversion mode to the PFM mode or the PWM mode by additionally considering at least one of a load current or a signal to interference noise ratio (SINR) of a physical layer.

[0088] According to various embodiments of the present disclosure, an electronic device (for example, Figure 1 The electronic device 101) can include a power management module (for example, the power management module 188), a communication processor (for example, the auxiliary processor 123), and at least one processor (for example, the main processor 121) operatively connected to the communication processor, wherein the at least one processor identifies whether an external device has been configured as ultra-reliable low latency communication (URLLC) in a case where the external device communicates with the electronic device using a wireless resource, and configures a voltage conversion mode of the power management module that supplies power to the communication processor to a pulse frequency modulation (PFM) mode or a pulse width modulation (PWM) mode based on whether the URLLC has been configured.

[0089] According to various embodiments of the present disclosure, the at least one processor can configure the voltage conversion mode of the power management module to the PWM mode in a case where communication with the external device has been configured as the URLLC, and configure the voltage conversion mode of the power management module to the PFM mode in a case where communication with the external device has not been configured as the URLLC.

[0090] According to various embodiments of the present disclosure, the power management module can include a direct current / direct current (DC-DC) converter, and the voltage conversion mode can include a voltage conversion mode of the DC-DC converter.

[0091] According to various embodiments of this disclosure, the at least one processor can determine whether communication with an external device has been configured as URLLC based on whether the modulation and coding scheme cell radio network temporary identifier (MCS-C-RNTI) is included in the radio resource control (RRC) signaling.

[0092] According to various embodiments of this disclosure, the at least one processor can configure the voltage conversion mode to PFM mode or PWM mode by taking into account the remaining power of the electronic device.

[0093] Figure 7 This is a flowchart 700 for configuring the voltage conversion mode of an electronic device based on the modulation order, according to embodiments of the present disclosure. In the following embodiments, the various operations may be performed sequentially or not necessarily sequentially. For example, the order of each operation can be changed, and at least two operations can be performed in parallel. For example, the electronic device may be... Figure 1 or Figure 2 Electronic device 101.

[0094] Reference Figure 7 According to various embodiments of this disclosure, in operation 701, the electronic device (e.g., Figure 1 The processor 120 or the wireless communication module 192, or Figure 2 The communication processor 220 or wireless communication module 230 can identify whether communication with an external electronic device is being performed. According to embodiments of this disclosure, the electronic device 101 can identify whether a wireless channel with an external electronic device has been established through the wireless communication module 192 or the wireless communication module 230.

[0095] According to various embodiments of this disclosure, even when the electronic device (e.g., processor 120 or processor 210) is not performing communication with an external electronic device (e.g., "No" in operation 701), although not shown in the figures, a switching mode for the power supply to the electronic device 101 can be maintained. According to embodiments of this disclosure, processor 120 or processor 210 can maintain a voltage switching mode based on load current configuration.

[0096] According to various embodiments of this disclosure, in the case of communication with an external electronic device (e.g., "Yes" in operation 701), in operation 703, the electronic device (e.g., processor 120 or processor 210) can identify whether the modulation order used for wireless communication exceeds a first reference order. As an example, the first reference order may include modulation order 7 corresponding to 128QAM.

[0097] According to various embodiments of the present disclosure, in case that the modulation order for wireless communication exceeds the first reference order (for example, "Yes" in operation 703), the electronic device (for example, the processor 120 or the processor 210) can configure the voltage conversion mode of the DC-DC conversion module 242 to the PWM mode in operation 705. According to an embodiment of the present disclosure, in case that the modulation order for wireless communication exceeds the first reference order, the processor 210 can determine that the noise occurring due to the PFM mode causes interference in wireless communication and the wireless communication performance (for example, transmission rate) is thus reduced. In order to maintain the wireless communication performance, the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 that supplies power to the internal circuit (for example, the communication processor 220) of the electronic device 101 to the PWM mode.

[0098] According to various embodiments of the present disclosure, in case that the modulation order for wireless communication is equal to or less than the first reference order (for example, "No" in operation 703), the electronic device (for example, the processor 120 or the processor 210) can configure the voltage conversion mode of the DC-DC conversion module 242 to the PFM mode in operation 707. According to an embodiment of the present disclosure, in case that the modulation order for wireless communication is equal to or less than the first reference order, the processor 210 can determine that the wireless communication is not sensitive to the noise generated due to the PFM mode. Thus, in order to reduce the current consumption, the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 that supplies power to the internal circuit (for example, the communication processor 220) of the electronic device 101 to the PFM mode.

[0099] According to various embodiments of the present disclosure, the electronic device 101 can configure the voltage conversion mode for supplying power to the internal circuit of the electronic device 101 to the PWM mode or the PFM mode based on the comparison result between the modulation order for wireless communication and the first reference order.

[0100] Figure 8 is a flowchart 800 for configuring a voltage conversion mode of an electronic device based on a modulation order and a load current according to an embodiment of the present disclosure. In the following embodiments, each operation can be sequentially performed, or can not necessarily be sequentially performed. For example, the order position of each operation can be changed, and at least two operations can be performed in parallel. For example, the electronic device can be Figure 1 or Figure 2 the electronic device 101 according to an embodiment of the present disclosure.

[0101] Referring to Figure 8 , according to various embodiments of the present disclosure, the electronic device (for example, Figure 1 the processor 120 or the wireless communication module 192 of the electronic device 101, or Figure 2The communication processor 220 or the wireless communication module 230) can identify whether communication with the external electronic device is performed. As an example, the communication with the external electronic device can include a series of operations of transmitting or receiving a signal through a wireless channel established between the electronic device 101 and the external electronic device.

[0102] According to various embodiments of the present disclosure, in the case where the electronic device (e.g., the processor 120 or the processor 210) does not perform communication with the external electronic device (e.g., "No" in operation 801), although not shown in the drawing, a conversion mode for power supply of the electronic device 101 can be maintained. As an example, the voltage conversion mode for power supply of the electronic device 101 can be configured based on a load current.

[0103] According to various embodiments of the present disclosure, in the case where communication with the external electronic device is performed (e.g., "Yes" in operation 801), the electronic device (e.g., the processor 120 or the processor 210) can identify whether a load current related to the power supply of the electronic device 101 exceeds a first reference current, in operation 803.

[0104] According to various embodiments of the present disclosure, in the case where the load current exceeds the first reference current (e.g., "Yes" in operation 803), the electronic device (e.g., the processor 120 or the processor 210) can identify whether a modulation order for wireless communication with the external electronic device exceeds a first reference order, in operation 805. As an example, the first reference order can be configured as a modulation order 7 corresponding to 128QAM.

[0105] According to various embodiments of the present disclosure, in the case where the modulation order for wireless communication exceeds the first reference order (e.g., "Yes" in operation 805), the electronic device (e.g., the processor 120 or the processor 210) can configure a voltage conversion mode of the DC-DC conversion module 242 as a PWM mode, in operation 807. According to embodiments of the present disclosure, in the PFM mode, supply of a relatively high load current can be limited, and interference affecting wireless communication can be possible. Accordingly, in the case where the load current exceeds the first reference current and the modulation order for wireless communication exceeds the first reference order, the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 as the PWM mode.

[0106] According to various embodiments of the present disclosure, in case that the load current is equal to or less than a first reference current (for example, "No" in operation 805) or a modulation order for wireless communication is equal to or less than a first reference order (for example, "No" in operation 805), the electronic device (for example, the processor 120 or the processor 210) can configure a voltage conversion mode of the DC-DC conversion module 242 to a PFM mode in operation 811.

[0107] Figure 9 is a flowchart 900 for changing a voltage conversion mode of an electronic device based on a modulation order and a load current according to an embodiment of the present disclosure. In the following embodiments, each operation can be sequentially performed, or can not necessarily be sequentially performed. For example, the order position of each operation can be changed, and at least two operations can be performed in parallel. For example, the electronic device can be Figure 1 or Figure 2 the electronic device 101.

[0108] Referring to Figure 9 , according to various embodiments of the present disclosure, the electronic device (for example, Figure 1 the processor 120 or the power management module 188, or Figure 2 the processor 210 or the power management module 240) can identify whether a voltage conversion mode of the DC-DC conversion module 242 is changed for communication of the electronic device in operation 901. According to an embodiment of the present disclosure, as in operations 701 to 707 of Figure 7 , the voltage conversion mode of the DC-DC conversion module 242 can be changed based on a modulation order. According to an embodiment of the present disclosure, as in operations 801 to 809 of Figure 8 , the voltage conversion mode of the DC-DC conversion module 242 can be changed based on a load current and a modulation order.

[0109] According to various embodiments of the present disclosure, in case that the voltage conversion mode of the DC-DC conversion module 242 is changed (for example, "Yes" in operation 901), the electronic device (for example, the processor 120, the wireless communication module 192, the communication processor 220, or the wireless communication module 230) can identify whether communication with an external electronic device is maintained in operation 903. According to an embodiment of the present disclosure, the processor 210 can identify whether a wireless channel with an external electronic device is maintained through the wireless communication module 230.

[0110] According to various embodiments of the present disclosure, in case that the voltage conversion mode of the DC-DC conversion module 242 is maintained (for example, "No" in operation 901), or in case that the communication with the external electronic device is not performed (for example, "No" in operation 903), the electronic device (for example, the processor 120 or 210) can maintain the voltage conversion mode of the electronic device 101. As an example, the voltage conversion mode of the electronic device 101 can be configured based on the load current.

[0111] According to various embodiments of the present disclosure, in case that the communication with the external electronic device is maintained (for example, "Yes" in operation 903), at operation 905, the electronic device (for example, the processor 120 or the processor 210) can identify whether the load current related to the power supply of the electronic device 101 is less than a second reference current. As an example, the second reference current can be configured as a value different from the first reference current of the Figure 8 .

[0112] According to various embodiments of the present disclosure, in case that the load current is less than the second reference current (for example, "Yes" in operation 905), at operation 907, the electronic device (for example, the processor 120 or the processor 210) can identify whether a modulation order for the wireless communication with the external electronic device is less than a second reference order. As an example, the second reference order can be configured as a modulation order 5 corresponding to 32QAM, which is different from the first reference order of the Figure 8 .

[0113] According to various embodiments of the present disclosure, in case that the modulation order for the wireless communication is less than the second reference order (for example, "Yes" in operation 907), at operation 909, the electronic device (for example, the processor 120 or the processor 210) can configure the voltage conversion mode of the DC-DC conversion module 242 as the PFM mode. According to embodiments of the present disclosure, in case that the load current is less than the second reference current and the modulation order for the wireless communication is less than the reference order, the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 as the PFM mode. As an example, in case that the voltage conversion mode is changed to the PWM mode in operation 901, at operation 909, the DC-DC conversion module 242 can change the voltage conversion mode to the PFM mode.

[0114] According to various embodiments of the present disclosure, in case that the load current is greater than the second reference current (for example, "No" in operation 905) or the modulation order is equal to or greater than the second reference order (for example, "No" in operation 907), at operation 911, the electronic device (for example, the processor 120 or the processor 210) can configure the voltage conversion mode of the DC-DC conversion module 242 as the PWM mode.

[0115] According to various embodiments of the present disclosure, the electronic device 101 can adaptively configure at least one of a reference current related to a load current or a reference order related to a modulation order, which determines whether to change the voltage conversion mode, to prevent the voltage conversion mode of the DC-DC conversion module 242 from frequently changing. According to embodiments of the present disclosure, Figure 9 the second reference current can be configured to be the same as Figure 8 the first reference current of the electronic device 101, and Figure 9 the second reference order can be configured to be different from Figure 8 the second reference order of the electronic device 101. According to embodiments of the present disclosure, Figure 9 the second reference current can be configured to be different from Figure 8 the first reference current of the electronic device 101, and Figure 9 the second reference order can be configured to be the same as Figure 8 the second reference order of the electronic device 101.

[0116] According to various embodiments of the present disclosure, in the case where the voltage conversion mode is changed to prevent the frequent change of the voltage conversion mode of the DC-DC conversion module 242, the electronic device 101 can maintain the changed voltage conversion mode for a predetermined duration. According to embodiments of the present disclosure, the reference value for determining whether to change the voltage conversion mode can be maintained to be the same as Figure 8 the reference value of the electronic device 101. As an example, the reference value for determining whether to change the voltage conversion mode can include at least one of a reference current related to a load current or a reference order related to a modulation order.

[0117] According to various embodiments of the present disclosure, the electronic device 101 can identify a modulation order for wireless communication based on a CQI index or an MCS index. According to embodiments of the present disclosure, the CQI index is identification information for indicating a CQI value, and a modulation mode supported by the CQI index can be configured as shown in Table 2 as defined in the standard document TS 36.213 or the standard document TS 38.214. The processor 120 or the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 based on the modulation mode related to the CQI index.

[0118] Table 2

[0119]

[0120] Referring to Table 2, CQI indexes from 1 to 11 can support a modulation mode of 64QAM or less, and CQI indexes from 12 to 15 can support a modulation mode of 256QAM. As an example, in a case where the CQI index is 11 or less, the processor 120 or the processor 210 can determine that the wireless communication is not sensitive to interference due to the PFM mode. Accordingly, in a case where the CQI index is 11 or less, the processor 120 or the processor 210 can configure a voltage conversion mode of the DC-DC conversion module 242 to the PFM mode. As an example, in a case where the CQI index exceeds 11, the processor 120 or the processor 210 can determine that the wireless communication is sensitive to interference due to the PFM mode. Accordingly, in a case where the CQI index exceeds 11, the processor 120 or the processor 210 can configure a voltage conversion mode of the DC-DC conversion module 242 to the PWM mode.

[0121] According to an embodiment of the disclosure, the MCS index is identification information for indicating an MCS value, and a modulation order supported by the MCS index can be configured as shown in Table 3 as defined in the standard document TS 36.213 or the standard document TS 38.214. The processor 120 or the processor 210 can configure a voltage conversion mode of the DC-DC conversion module 242 based on a modulation order related to the MCS index.

[0122] Table 3

[0123]

[0124]

[0125] Referring to Table 3, MCS indexes from 0 to 19 can support a modulation mode of 6 or less, and MCS indexes from 20 to 27 can support a modulation mode of 8. As an example, in a case where the MCS index is 19 or less, the processor 120 or the processor 210 can determine that the wireless communication is not sensitive to the influence of interference due to the PFM mode. Accordingly, in a case where the MCS index is 19 or less, the processor 120 or the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 to the PFM mode. As an example, in a case where the MCS index is 20 or more, the processor 120 or the processor 210 can determine that the wireless communication is sensitive to the influence of interference due to the PFM mode. Accordingly, in a case where the MCS index is 20 or more, the processor 120 or the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 to the PWM mode. As an example, the wireless communication based on the code rate (e.g., channel code level) can have robustness to interference. Accordingly, the processor 120 or the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 based on a combination of the MCS index and the target code rate.

[0126] According to an embodiment of the disclosure, as shown in Table 4 defined in a standard document TS 36.213, the MCS index is identification information for indicating an MCS value, and a modulation order supported by the MCS index related to the downlink can be configured. The processor 120 or the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 based on the modulation order related to the MCS index.

[0127] Table 4

[0128]

[0129]

[0130]

[0131] Referring to Table 4, MCS indices from 0 to 14 and from 19 to 29 can support a modulation mode of 6 or less, and MCS indices from 15 to 26 and from 30 to 31 can support a modulation mode of 8 or more. As an example, in a case where the MCS index is 14 or less, the processor 120 or the processor 210 can determine that the wireless communication is not sensitive to the influence of interference due to the PFM mode. Accordingly, in a case where the MCS index is 14 or less, the processor 120 or the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 to the PFM mode. As an example, in a case where the MCS index is in the range of 15 to 26, the processor 120 or the processor 210 can determine that the wireless communication is sensitive to the influence of interference due to the PFM mode. Accordingly, in a case where the MCS index is in the range of 15 to 26, the processor 120 or the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 to the PWM mode.

[0132] Figure 10A and Figure 10B are graphs illustrating a relationship between a CQI index or an MCS index and a modulation order according to various embodiments of the disclosure.

[0133] Referring to Figure 10A , the horizontal axis can indicate time, and the vertical axis can indicate a CQI index. Referring to Figure 10B , the horizontal axis can indicate time, and the vertical axis can indicate an MCS index.

[0134] According to various embodiments of the disclosure, in a case where the electronic device 101 provides a long term evolution (LTE) communication service, as illustrated in Figure 10A , a CQI index of 11 or less can be maintained for a relatively long time. According to an embodiment of the disclosure, in a case where the CQI index is 11 or less, the electronic device 101 can configure the voltage conversion mode of the DC-DC conversion module 242 to the PFM mode. For example, the electronic device 101 can reduce the current consumed by voltage conversion, because the duration in which the voltage conversion module is configured to the PFM mode is relatively longer than the duration in which the voltage conversion module is configured to the PWM mode in the LTE communication service.

[0135] According to various embodiments of the disclosure, in a case where the electronic device 101 provides a long term evolution (LTE) communication service, as illustrated in Figure 10BAs shown, an MCS index of 19 or less can be maintained for a relatively long time. According to embodiments of this disclosure, when the MCS index is 19 or less, the electronic device 101 can configure the voltage conversion mode of the DC-DC conversion module 242 to PFM mode. For example, the electronic device 101 can reduce the current consumed by the voltage conversion because, in LTE communication services, the voltage conversion module is configured in PFM mode for a relatively longer period than the voltage conversion module is configured in PWM mode.

[0136] Figure 11 This is a graph illustrating the correlation between CQI and MCS according to embodiments of the present disclosure. In the following description, in Figure 11 In the diagram, the horizontal axis can indicate the CQI (or CQI index), and the vertical axis can indicate the MCS (or MCS index).

[0137] Reference Figure 11 According to various embodiments of this disclosure, the CQI index and the MCS index can have similar trends (1100). For example, the CQI index can increase proportionally to the MCS index. According to various embodiments of this disclosure, such as Figure 11 As shown, the CQI index can have a different trend than the MCS index. For example, in cases where the required data transfer rate is low despite a high CQI, the MCS index can be configured to be low.

According to embodiments of the present disclosure, in the case where the load current is changed, the processor 210 can change the voltage conversion mode based on the changed load current.

[0141] According to various embodiments of the present disclosure, in the case where communication with the external electronic device is not performed (for example, "No" in operation 1201), although not shown in the drawing, the electronic device (for example, the processor 120 or 210) can maintain the voltage conversion mode configured based on the load current.

According to an embodiment of the present disclosure, in the case where the RRC signaling configured as "qam64LowSE" is received from the external electronic device, the processor 210 can determine that the modulation order of the PDSCH is configured as 6 (e.g., corresponding to 64QAM). The processor 210 can determine that the wireless communication based on the corresponding modulation order is not sensitive to the noise generated due to the PFM mode, and thus can configure the voltage conversion mode of the DC-DC conversion module 242 as the PFM mode.

Figure 1 Figure 2 According to various embodiments of the disclosure, in the case where the RRC connection with the external electronic device is released (e.g., "No" in operation 1301), the electronic device (e.g., the processor 120 or the processor 210) can maintain the voltage conversion mode of the electronic device 101.

[0151] According to various embodiments of the disclosure, in the case where the RRC connection with the external electronic device is maintained (e.g., "Yes" in operation 1301), at operation 1303, the electronic device (e.g., the processor 120 or 210) can identify whether a current time is included in a DRX active duration (DRX in duration). As an example, the DRX active duration can include at least a part of a period in which the electronic device 101 monitors a physical downlink control channel (PDCCH).

[0152] According to various embodiments of the disclosure, in the case where the current time is included in the DRX active duration (e.g., "Yes" in operation 1303), at operation 1305, the electronic device (e.g., the processor 120 or the processor 210) can configure a voltage conversion mode of the DC-DC conversion module 242 based on an RRC variable. According to an embodiment of the disclosure, as in operations 1201 to 1209 of the electronic device 101,

[0153] According to various embodiments of the disclosure, in the case where the current time is included in the DRX active duration (e.g., "Yes" in operation 1303), at operation 1305, the electronic device (e.g., the processor 120 or the processor 210) can configure a voltage conversion mode of the DC-DC conversion module 242 based on an RRC variable. According to an embodiment of the disclosure, as in operations 1201 to 1209 of the electronic device 101, Figure 12

[0154] ​​According to various embodiments of the present disclosure, in the case where the current time is not in the DRX active duration (for example, "No" in operation 1303), in operation 1307, the electronic device (for example, the processor 120) can configure the voltage conversion mode of the DC-DC conversion module 242 to the PFM mode. According to embodiments of the present disclosure, in the case of the DRX inactive duration, wireless communication is not performed, and thus the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 to the PFM mode to reduce energy consumption.

[0155] Figure 14 is a flowchart 1400 for configuring a voltage conversion mode of an electronic device based on L1-SINR according to embodiments of the present disclosure. In the following embodiments, each operation can be sequentially performed, or can not necessarily be sequentially performed. For example, the order position of each operation can be changed, and at least two operations can be performed in parallel. For example, the electronic device can be Figure 1 or Figure 2 the electronic device 101.

[0156] Referring to Figure 14 , according to various embodiments of the present disclosure, in operation 1401, the electronic device (for example, Figure 1 the processor 120 or the wireless communication module 192 of the electronic device 101, or Figure 2 the communication processor 220 or the wireless communication module 230 of the electronic device 101) can identify whether communication with an external electronic device is performed through a wireless resource. According to embodiments of the present disclosure, the processor 210 can identify whether data is received or transmitted through a wireless channel between the electronic device and the external electronic device by using the wireless communication module 230.

[0157] According to various embodiments of the present disclosure, in the case where communication with the external electronic device is not performed (for example, "No" in operation 1401), although not shown in the drawing, the electronic device (for example, the processor 120 or 210) can maintain the voltage conversion mode of the electronic device 101.

[0158] According to various embodiments of the present disclosure, in the case where communication with the external electronic device is performed (for example, "Yes" in operation 1401), in operation 1403, the electronic device (for example, the processor 120 or the processor 210) can identify whether the SINR of the physical layer (L1-SINR) exceeds a reference value. As an example, the SINR of the physical layer can be calculated based on at least one of a SS / PBCH block (SSB), an NZP-CSI-RS, or a ZP-CSI-RS of the physical layer L1.

[0159] According to various embodiments of the present disclosure, in case that the SINR of a physical layer (L1-SINR) exceeds a reference value (for example, "Yes" in operation 1403), at operation 1405, the electronic device (for example, the processor 120 or the processor 210) can configure a voltage conversion mode of the DC-DC conversion module 242 to a PWM mode. According to an embodiment of the present disclosure, in case that the SINR of a physical layer (L1-SINR) exceeds a reference value, data can be transmitted at a high speed, and thus the processor 210 can determine that it is sensitive to an interference effect due to a PFM mode. The processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 to the PWM mode to maintain a wireless communication performance.

[0160] According to various embodiments of the present disclosure, in case that the SINR of a physical layer (L1-SINR) is equal to or less than a reference value (for example, "No" in operation 1403), at operation 1407, the electronic device (for example, the processor 120 or the processor 210) can configure a voltage conversion mode of the DC-DC conversion module 242 to a PFM mode. According to an embodiment of the present disclosure, in case that the SINR of a physical layer (L1-SINR) is equal to or less than a reference value, high-speed data transmission is limited, and thus the processor 210 can determine that it is not sensitive to an interference effect due to a PFM mode. The processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 to the PFM mode to reduce current consumption.

[0161] According to various embodiments of the present disclosure, the electronic device 101 can configure a voltage conversion mode of the DC-DC conversion module 242 based on a comparison result between a reference value and an interference part of the SINR of a physical layer.

For example, the order position of each operation can be changed, and at least two operations can be performed in parallel. For example, the electronic device can be Figure 1 or Figure 2 the electronic device 101.

[0165] According to various embodiments of the disclosure, in the case where wireless communication with the external electronic device is performed (for example, "Yes" in operation 1501), the electronic device (for example, the processor 120 or the processor 210) can identify whether a modulation order for wireless communication with the external electronic device exceeds a fourth reference order in operation 1503. As an example, the fourth reference order can include a modulation order 7 corresponding to 128QAM.

[0166] According to various embodiments of the disclosure, in the case where the modulation order for wireless communication with the external electronic device exceeds the fourth reference order (for example, "Yes" in operation 1503), the electronic device (for example, the processor 120 or the processor 210) can identify whether a SINR of a physical layer (L1-SINR) exceeds a reference value in operation 1505.

[0167] According to various embodiments of the disclosure, in the case where the SINR of the physical layer (L1-SINR) exceeds the reference value (for example, "Yes" in operation 1505), the electronic device (for example, the processor 120 or the processor 210) can configure a voltage conversion mode of the DC-DC conversion module 242 as a PWM mode in operation 1507. According to an embodiment of the disclosure, in the case where the modulation order for wireless communication exceeds the fourth reference order and the SINR of the physical layer (L1-SINR) exceeds the reference value, the processor 210 can determine that the interference effect due to the PFM mode is sensitive. Accordingly, the processor 210 can configure the voltage conversion mode of the DC-DC conversion module 242 as the PWM mode.

[0168] According to various embodiments of this disclosure, in operation 1509, when the modulation order for wireless communication is equal to or less than the fourth reference order (e.g., "No" in operation 1503) or the physical layer SINR (L1-SINR) is equal to or less than a reference value (e.g., "No" in operation 1505), the electronic device (e.g., processor 120 or processor 210) can configure the voltage conversion mode of the DC-DC conversion module 242 to PFM mode. According to embodiments of this disclosure, when the modulation order for wireless communication is equal to or less than the fourth reference order or the physical layer SINR (L1-SINR) is equal to or less than a reference value, processor 210 can determine that it is insensitive to interference effects caused by the PFM mode. Therefore, processor 210 can configure a PFM mode with relatively good voltage conversion efficiency as the voltage conversion mode of the DC-DC conversion module 242.
