Figure 2 is a block diagram of an electronic device, according to one embodiment.

In FIG. 2 , descriptions of components defined with the same names as those of FIG. 1 may be replaced with descriptions of components included in the electronic device 101 of FIG. 1 described above. For example, the description of the processor 220, memory 230, power management circuit 250, and antenna 297 in FIG. 2 refers to the processor 120 in FIG. 1 (e.g., the auxiliary processor in FIG. 1 (e.g., 123)), memory 130, power management module 188, and antenna module 197 may be referred to.

According to one embodiment, the electronic device 201 may include a processor 220, a memory 230, a power management circuit 250, a transmission circuit 260, a transceiver 270, and an antenna 297. . In FIG. 2 , the transmitting circuit 260 and the transceiver 270 are shown as separate components, but embodiments of the present disclosure are not limited thereto. For example, the transmission circuit 260 and transceiver 270 may be components included and/or disposed in a communication module (e.g., communication module 190 of FIG. 1). For example, the transmit circuit 260, transceiver 270, and power management circuit 250 may be included in one communication module (e.g., communication module 190 of FIG. 1. For example, processor 220 ) may be implemented with a memory 230 and a chipset. The processor 220 may include at least one of a communication processor or a modem.

In one embodiment, processor 220 may be operatively coupled with memory 230, power management circuitry 250, transmission circuitry 260, transceiver 270, and antenna 297. The processor 220 may control various operations related to power supply of the power management circuit 250 using the transceiver 270. For example, if component A is “operably connected” to component B, A can control the functions of B by transmitting signals to B through an electrical or wireless connection to B.

For example, the processor 220 may establish communication with an external device 202 (eg, a base station) using the transmission circuit 260. The processor 220 may identify at least one designated condition among a plurality of conditions related to communication performance of the electronic device 201. In one example, processor 2220 may identify at least one specified condition from information stored in memory 230.

As an example, the processor 220 may identify whether a specified condition is satisfied based on the quality of the received signal of the electronic device 201. For example, the electronic device 201 may identify that a specified condition is satisfied when the SNR of the received signal is less than a threshold. As an example, the processor 220 measures the received signal reference power (RSRP) and SNR for a specified time, and during the specified time, the measured RSRP has a first value corresponding to a first time and a second time, respectively. 1 SNR and 2nd SNR can be identified. If at least one of the first SNR and the second SNR is identified as being less than a threshold, the processor 220 may determine that a specified condition is satisfied. For example, processor 220 determines that the identified RSRP at a first point in time during the specified time is -110 dBm and that the identified RSRP at a second point in time (e.g., a subsequent point in the time domain relative to the first point in time) is -110 dBm. In this case, the SNR at the first time point and the second time point can be calculated. If the SNR at the first time point is 12 dB and the SNR at the second time point is 7 dB, the processor 220 determines that the SNR at the second time point, 7 dB, is identified as being less than a threshold (e.g., 10 dB). It may be determined that the condition is satisfied. Based on the decrease in SNR, the processor 220 may determine that the reception sensitivity of the electronic device has deteriorated at the second time point compared to the first time point.

As an example, the processor 220 may identify whether a specified condition associated with the communication state between the electronic device 201 and the external device 202 is satisfied based on whether a call (or call) is performed. For example, when the electronic device 202 is identified as receiving or making a call, the processor 220 manages power based on the communication state (or mode) between the electronic device 201 and the external device 202. The connection state between the circuit 250 and the transmission circuit 260 can be changed. An embodiment of changing the connection state between the plurality of power management circuits 250 and the plurality of transmission circuits 260 may be described in more detail later in the description of FIGS. 3 to 6 below.

As an example, the processor 220 may identify whether a specified condition is satisfied based on the quality of the received signal obtained through the antenna 297. For example, when the processor 220 identifies that the antenna 297 is operating, the specified condition is set if the SNR of the received signal obtained through the antenna 297 among the received signals of the electronic device 201 is less than a threshold. It can be identified as being satisfied. The processor 220 may measure the SNR of the received signal obtained through the antenna 297 for a specified time. If at least some of the measured SNR is identified as being less than the threshold, the processor 220 may determine that the specified condition is satisfied. For example, the antenna 297 may be an antenna disposed separately from the transmission circuit 260. Antenna 297 may be, for example, a UWB antenna.

For example, the processor 220 may determine whether at least one specified condition identified among the plurality of conditions is satisfied.

As an example, the processor 220 may determine whether a plurality of specified conditions are satisfied. In one example, the processor 220 may identify whether a plurality of specified conditions are satisfied based on the status and/or type of wireless communication between the electronic device 201 and the external device 202. In one example, the processor 220 may identify whether a plurality of conditions are satisfied based on the connection state between the power management circuit 250 and the transmission circuit 260. In this case, the processor 220 may operate an algorithm associated with one condition among a plurality of specified conditions that are satisfied based on the specified priority. The designated priority may be a priority previously defined by the user. Additionally or alternatively, the assigned priority may depend on the state of communication with the power management circuitry 250, transmission circuitry 260, and/or external device 202 (e.g., SA operating state, NSA operating state, or CA operating state). It may be a variable priority determined by . In one embodiment, the processor 220 may identify whether a value (eg, SNR) associated with the quality of a received signal of the electronic device 201 is less than a threshold as the first priority. In one embodiment, the processor 220 may identify whether the SNR of the received signal obtained through the antenna 297 among the received signals of the electronic device 201 is less than a threshold as a second priority. In one embodiment, the processor 220 may identify the communication state with the external device 202 identified while the electronic device 201 is receiving or making a call as the third priority. The above-described priorities are illustrative, and embodiments of the present disclosure are not limited thereto. For example, priorities can be changed by user settings.

For example, the processor 220 may change the connection state of the power management circuit 250 and the transmission circuit 260 based on the specified condition being satisfied. As an example, the processor 220 may transmit a control signal to change the connection target of the switch 261 included in the transmission circuit 260 to the transceiver 270. When there are a plurality of transmission circuits 260 and power management circuits 250, the control signal includes information about the transmission circuit to be controlled, information about the power management circuit to be connected, and/or the switch 261. It may contain information about changes in connection status. The transceiver 270 may transmit the control signal received from the processor 220 to the transmission circuit 260 based on the information. The transmission circuit 260 may change the electrical connection between the power management circuit 250 and the transmission element 262 based on the control signal received from the transceiver 270. For example, the transmission circuit 260 can change the electrical connection between the power management circuit 250 and the transmission element 262 by controlling the switch 261. An embodiment in which the electronic device 201 includes a plurality of power management circuits 250 and a plurality of transmission circuits 260 may be described in more detail later in the description of FIGS. 3 to 6 below.

In one embodiment, memory 230 may store instructions or data. For example, the memory 230 may store one or more instructions that, when executed by the processor 220, allow the electronic device 201 to perform various operations. For example, the memory 230 may store various information related to the connection status of the power management circuit 250 and the transmission circuit 260. As an example, the memory 230 may store a plurality of conditions related to communication performance of the electronic device. As an example, the memory 230 may store a designated priority for selecting at least one designated condition when two or more conditions among the plurality of conditions are satisfied. The designated priority may be a priority previously defined by the user. Additionally or alternatively, the assigned priority may be a variable priority that is determined or changed depending on the state of communication with the power management circuit 250, transmission circuit 260, and/or external device 202.

For example, memory 230 may store information regarding power management circuit 250 and transmission circuit 260. For example, when the electronic device 201 includes a plurality of power management circuits 250 and a plurality of transmission circuits 260, information about the power management circuit 250 and the transmission circuit 260 may be stored in each power management circuit. Information about the bandwidth supported by the circuit 250, the maximum transmission power of each transmission circuit 260, and/or the connection structure of the power management circuit 250 and the switch 261 included in the transmission circuit 260. may include.

In one embodiment, power management circuitry 250 may include at least one sensor 251 and protection circuitry 252, but this is illustrative and power management circuitry may include a controller, at least one regulator, and/or Additional elements may be included. For example, the controller may include a converter (eg, DC/DC converter) and/or a plurality of capacitors. For example, the at least one regulator may include a boost converter, a buck converter, and/or a linear regulator. For example, the passive element may include a plurality of inductors. Power management circuit 250 may be operatively coupled with a battery (e.g., battery 189 in FIG. 1), transmission circuit 260, and/or transceiver 270.

For example, the power management circuit 250 may efficiently convert voltage to supply voltages of various magnitudes to components of the electronic device 201 using at least one regulator. For example, at least one regulator may output an input direct current (DC) voltage as a stabilized DC voltage or linearly adjust a linear envelope signal.

For example, power management circuit 250 may include various types of regulators. As an example, the power management circuit 250 may further include a boost converter and a buck converter, which are types of switching regulators. The switching regulator can generate an output voltage at high speed using the on/off of the switching element. Switching regulators can step up or down the input voltage with high efficiency and low heat generation. For example, a boost converter can output output by boosting the input voltage. For example, a buck converter can output by stepping down the input voltage. As an example, the power management circuit 250 may include a linear regulator that adjusts the gain of the output voltage using a variable resistor. A linear regulator can amplify the input voltage by a specified gain and output it. A linear regulator can linearly output a wideband envelope signal.

For example, the power management circuit 250 may be electrically connected to the transmission circuit 260. As an example, the power management circuit 250 may be operatively connected to a power amplifier (PA) included in the transmission circuit 260 through a switch 261.

For example, at least one sensor 251 included in the power management circuit 250 may measure information related to the operating state of the power management circuit 250 based on a designated period. As an example, at least one sensor 251 may measure the temperature of the power management circuit 250. The processor 220 may change the connection state between the power management circuit 250 and the transmission circuit 260 based on the measured temperature.

For example, the protection circuit 252 included in the power management circuit 250 may include various types of blocking circuits. As an example, the protection circuit 252 may include an overcurrent protection (OCP) circuit, an overvoltage protection (OVP) circuit, and/or an undervoltage lockout (UVLO) circuit. If malfunction or failure of the power management circuit 250 is identified, the processor 220 may activate at least a portion of the protection circuit 252.

In one embodiment, the transmitting circuit 260 may perform wireless communication based on various communication protocols (e.g., long term evolution (LTE) communication, new radio (NR) communication). For example, transmission circuit 260 may include switch 261 and transmission element 262. Transmit circuit 260 may be referred to as a radio frequency front end (RFFE).

For example, transmit circuit 260 may include a power amplifier. The power amplifier may amplify and output the strength of the input signal based on the size of the power (eg, driving voltage) transmitted from the power management circuit 250. The magnitude of the driving voltage may be determined based on the operation mode of the transmission circuit 260.

For example, transmission circuit 260 may include switch 261 . The switch 261 may be provided to selectively connect at least one of the transmission circuit 260 and two or more power management circuits 250. A description of the connection structure of the switch 261 may be described in more detail later in the description of FIGS. 3 to 6 below.

For example, transmit circuit 260 may include transmit element 262. The transmitting element 262 may include a power amplifier, a duplexer, at least one antenna, an antenna switch module (ASM), and/or a low-noise amplifier (LNA). The transmission circuit 260 can amplify the transmission and reception signals using the transmission element 262 and communicate with the external device 202. For example, transmit element 262 may include at least one transmit RF path coupled to at least one antenna (not shown).

In one embodiment, transceiver 270 may be operatively coupled with processor 220 and power management circuitry 250. For example, the transceiver 270 may transmit the control signal received from the processor 220 to the transmission circuit 260. For example, the transceiver 270 may transmit a signal for power control to the power management circuit 250.

For example, the transceiver 270 is configured for wireless communication between the electronic device 201 and the external device 202 based on the control signal and based on the network 299 (e.g., the second network 199 in FIG. 1). The power management circuit 250 and transmission circuit 260 to be used can be identified, and signal power suitable for communication can be identified.

For example, the transceiver 270 may identify information about the communication performance of the electronic device 201 and transmit it to the processor 220. For example, transceiver 270 may identify and transmit the SNR associated with the receive sensitivity to processor 220. When the processor 220 generates a control signal to change (or update) the connection status of the power management circuit 250 and the transmission circuit 260 based on the received SNR and transmits it to the transceiver 270, the transceiver ( 270 can control the operation by connecting the power management circuit 250 and the transmission circuit 260 based on the received control signal.

In one embodiment, the antenna 297 may include at least one radiator for transmitting and receiving wireless signals based on a designated radio access technology (RAT). For example, the designated wireless communication technology may be an ultra wide band (UWB) communication technology (hereinafter referred to as 'UWB'). In one example, UWB may refer to a wireless communication technology that uses a wide frequency band of several GHz or more in a baseband state. In one example, UWB may refer to a wireless communication technology that utilizes low spectral density and short pulse width (e.g., 1 to 4 nano seconds). The antenna 297 may be defined as a component provided separately from the transmission element 262 included in the transmission circuit 260. For example, the antenna 297 may be connected to the UWB communication module and may not be electrically connected to the transmitting element 262.

For example, the electronic device 201 may communicate based on packets defined in a designated wireless communication technology. As an example, communication between the electronic device 201 and the external electronic device 202 may be based on physical (PHY) layer packets defined in UWB. In one embodiment, a PHY layer packet may include a synchronization header (SHR), a PHY header (PHR), and a PHY service data unit (PSDU). In one embodiment, the SHR may be added prior to the PHR. SHR sets automatic gain control (AGC), antenna diversity selection, timing acquisition, coarse and fine frequency recovery, packet and frame synchronization, channel tracking, or ranging procedures. It can be used for at least one of the following. In one embodiment, the ranging procedure may include measuring the distance between an electronic device and an external electronic device. In one embodiment, SHR may include synchronization (SYNC) and start-of-frame delimiter (SFD). In one embodiment, the PHR may be added after the SHR. PHR may contain control information related to PHY layer packets. For example, the PHR may include at least one of the data rate used to transmit the PSDU, the duration of the preamble (eg, SYNC), the length of the PSDU, or information for detecting errors in the PHR. In one embodiment, the PHR may consist of 19 bits. In one embodiment, the PSDU may include data (or content data) that the electronic device and an external electronic device want to transmit or receive. In one embodiment, a PSDU may consist of 0 bytes to 127 bytes. In one embodiment, SYNC may be formed of at least one symbol. At least one symbol may be a pulse representing 0, -1, or 1. In one embodiment, SYNC may be referred to as a preamble.

The components of the electronic device 201 shown in FIG. 2 are illustrative, and embodiments of the present disclosure are not limited thereto. For example, the electronic device 201 further includes components not shown in FIG. 2 (e.g., the sensor module 176 in FIG. 1) or includes components shown in FIG. 2 (e.g., at least one It may not include the sensor 251). For example, the electronic device 201 may further include a receiving circuit including at least one RF path for receiving a signal through the network 299 . In one example, the transmit circuit 260 and the receive circuit may be included in one chip or module.

Figure 3 is a block diagram of components included in an electronic device, according to an embodiment.

According to one embodiment, an electronic device (e.g., the electronic devices 101 and 201 of FIG. 1 or 2) includes a processor 220, a transceiver 270, a plurality of power management circuits 351 and 352, and a plurality of power management circuits 351 and 352. It may include a transmission circuit (361, 362,..., 369).

In one embodiment, the first transmission circuit 361 may include a first switch 3611 and a first transmission element 3612. In one embodiment, the second transmission circuit 362 may include a second switch 3621 and a first transmission element 3622. The third transmission circuit 369 may include a third switch 3691 and a third transmission element 3692.

In one embodiment, the processor 220 may be electrically connected to the transceiver 270. The processor 220 can change (or update) the connection state between the plurality of power management circuits 351 and 352 and the plurality of transmission circuits 361, 362,..., 369 using the transceiver 270. .

In one embodiment, the first power management circuit 351 may be electrically connected through a first connection based on the connection state of the first transmission circuit 361 and the first switch 3611. In one embodiment, the second power management circuit 352 may be electrically connected through a second connection based on the connection state of the first transmission circuit 361 and the first switch 3611.

In one embodiment, the first power management circuit 351 may be electrically connected through a third connection based on the connection state of the second transmission circuit 362 and the second switch 3621. In one embodiment, the second power management circuit 352 may be electrically connected through a fourth connection based on the connection state of the second transmission circuit 362 and the second switch 3621.

The connection between the above-described plurality of power management circuits 351 and 352 and the plurality of transmission circuits 361, 362,..., 369 is illustrative, and embodiments of the present disclosure are not limited thereto. For example, the electronic device may further include a third power management circuit 369. The first transmission circuit 361 operates at least one of the first power management circuit 351, the second power management circuit 352, and the third power management circuit 369 based on the connection state of the first switch 3611. Can be optionally connected to.

In one embodiment, the processor 220 may identify a specified condition among a plurality of conditions related to communication performance of the electronic device. In one example, processor 220 may identify at least one specified condition from information stored in memory (e.g., memory 230 of FIG. 2). If there are at least two specified conditions, the processor 220 may use the specified priority to select one condition.

For example, the processor 220 may identify whether a specified condition is satisfied based on the specified priority and the quality of the received signal of the electronic device. In one example, the processor 220 may identify whether the SNR of the received signal of the electronic device is less than a threshold using a specified condition. Processor 220 may measure RSRP and SNR for a specified period of time. The processor 220 may identify the first SNR and the second SNR corresponding to the first and second time points, respectively, at which the measured RSRP has the first value during the specified time. If at least one of the first SNR and the second SNR is identified as being less than a threshold, the processor 220 may determine that a specified condition is satisfied.

For example, based on the specified priority, the processor 220 may select a designated device associated with the communication state between the electronic device and an external device (e.g., the external device 202 in FIG. 2) when the electronic device is receiving or making a call. It is possible to identify whether the condition is satisfied. When the electronic device is identified as receiving a call or making a call, the processor 220 identifies the communication status with the electronic device and the base station (e.g., external device 202 in FIG. 2) and, based on the identified communication status, You can perform the following operations.

As an example, when the electronic device is identified as communicating with the base station based on the SA operating state, the processor 220 determines which of the first power management circuit 351 and the second power management circuit 352 has low audible noise. A predefined second power management circuit 352 can be identified. The processor 220 may control the first switch 3611 so that the identified second power management circuit 352 turns on the second connection for supplying power to the first transmission circuit 361. The processor 220 may transmit a control signal for the second connection of the first switch 3611 to the first transmission circuit 361 through the transceiver 270.

As an example, if the electronic device is identified as communicating with the base station based on the NSA operation state or the CA operation state, the processor 220 may use the connected mode (CDRX) of the first transmission circuit 361 and the second transmission circuit 362. At least one transmitting circuit in operation can be identified based on discontinuous reception. CDRX can be defined as a technology that reduces power consumption by maintaining communication in an idle state during a period in which specific data signals are not transmitted or received during wireless communication between an electronic device and a base station. For example, if the first transmit circuit 361 is identified as operating based on CDRX, then the second transmit circuit 361 between the first transmit circuit 361 and the second power management circuit 352 that is predefined as having low audible noise. The first switch 3611 can be controlled to turn on the connection. The processor 220 may control the second switch 3621 to turn on the third connection between the second transmission circuit 362 and the first power management circuit 351. The first transmission circuit 361 and/or the second transmission circuit 362 includes a plurality of power management circuits 351, 352,..., 359 based on the control signal received from the processor 220 through the transceiver 270. The electrical connection between and the transmitting elements 3612 and 3612 can be changed. For example, the first transmission circuit 361 and the second transmission circuit 362 control the first switch 3611 and the second switch 3612, respectively, based on the received control signal, thereby forming a plurality of power management circuits ( The electrical connection between 351, 352,..., 359) and the transmitting element (3612, 3612) can be changed.

For example, when both the first transmission circuit 361 and the second transmission circuit 362 are identified as operating based on CDRX, the Tx cycle of each transmission circuit can be identified. For example, the Tx cycle can be defined as the cycle between the start point and end point of the idle state while performing CDRX-based communication. For example, the processor 220 may identify a first Tx cycle of the first transmission circuit 361 and a second Tx cycle that is higher than the first Tx cycle of the second transmission circuit. The processor 220 may control the first switch 3611 to turn on the second connection between the first transmission circuit 361 and the second power management circuit 352, which is predefined as having low audible noise. The processor 220 may control the second switch 3621 to turn on the third connection between the second transmission circuit 362 and the first power management circuit 351.

For example, the processor 220 includes at least one antenna (e.g., in FIG. 2) disposed spaced apart from the first power management circuit 351, the second power management circuit 352, and the first transmission circuit 361. It is possible to identify whether the antenna 297) is operating. In one example, the processor may identify whether a specified condition is satisfied based on the quality of a received signal obtained through at least one antenna identified as operating. In one example, if at least one antenna is identified as operating, processor 220 determines whether the SNR of the received signal obtained through the identified at least one antenna is below a threshold based on the specified priority. It can be identified as being satisfied. Processor 220 may, for example, measure the SNR for a specified period of time. If at least some of the measured SNR is identified as being less than the threshold, the processor 220 may determine that the specified condition is satisfied.

As an example, the first separation distance between the first transmission and reception path between the first power management circuit 351 and the first transmission circuit 361 and at least one antenna is the second power management circuit 352 and the first transmission circuit 361. ) may be shorter than the second separation distance between the second transmission and reception path and at least one antenna. Accordingly, the processor 220 may identify that at least one antenna is relatively more affected by signals transmitted and received through the first transmission and reception path. Accordingly, the processor 220 turns off the first connection using the transceiver 270 and then turns on the second connection for supplying power to the first transmission circuit 361 by the second power management circuit 352. Deterioration of the reception sensitivity of one antenna can be prevented.

For example, the processor 220 changes the connection state (or, update) can be done.

For example, the processor 220 may monitor whether the first protection circuit of the first power management circuit 351 and the second protection circuit of the second power management circuit 352 are activated based on a designated cycle. For example, when the first protection circuit is identified as being activated, the communication state between the electronic device and the base station can be identified. For example, the electronic device may communicate with the base station using the first transmission circuit 361 that receives power from the second power management circuit 352. For example, if the electronic device is identified as communicating based on the SA operating state with the base station using the first transmission circuit 361, the power is supplied to the first transmission circuit 361 based on the second connection. The first switch 3611 can be controlled to maintain the current connection state. For example, if the electronic device is identified as using the first transmission circuit 361 to communicate with the base station based on the NSA operation state or the CA operation state, the second power management circuit 352 is configured to use the second transmission circuit ( The second switch 3621 can be controlled to turn on the fourth connection to supply power to 362). Accordingly, based on identifying that the first protection circuit is activated, the processor 220 determines that the first power management circuit 351 is in a faulty or malfunctioning state, and determines that the first power management circuit 351 is connected to the transmitting circuits. You can control the connection status so that no power is supplied.

For example, the processor 220 may control the connection state using heat generation information of the plurality of power management circuits 351, 352,..., 359. As an example, the processor 220 may measure the first temperature of the first power management circuit 351 and the second temperature of the second power management circuit 352 using at least one sensor. For example, when the second temperature is identified as being higher than the first temperature, the first switch 3611 may be controlled to turn off the second connection and turn on the first connection. Accordingly, the processor 220 can enhance communication performance of the electronic device by supplying power using the second power management circuit 352 that operates at a relatively low temperature.

For example, the processor 220 may control the connection state based on information related to the performance of the plurality of power management circuits 351, 352,..., 359. As an example, the processor 220 identifies the bandwidth supported by the plurality of power management circuits 351, 352,..., 359, identifies the size relationship of each bandwidth, and provides bandwidth to a transmission circuit requiring high transmission power. The connection state can be controlled so that this large power management circuit is connected. For example, the processor 220 identifies the first transmission power of the first transmission circuit 361 and the second transmission power of the second transmission circuit 362, and when the first transmission power is greater than the second transmission power, The first switch 3611 is controlled to turn on the first connection between the first power management circuit 351 and the first transmission circuit 361, and the second transmission circuit 362 is connected to the second power management circuit 351 or The second switch 3621 or the third switch 3691 can be controlled to be connected to one of the third power management circuits 359.

In the description of FIGS. 4 to 6 below, an embodiment for changing the connection state between the power management circuit and the transmission circuit will be described later.

Figure 4 is a block diagram of components included in an electronic device, according to an embodiment.

According to one embodiment, an electronic device (e.g., the electronic devices 101 and 201 of FIGS. 1 and 2) includes a first power management circuit 451 (e.g., the power management circuit 351 of FIG. 3) and a second power management circuit 451 (e.g., the power management circuit 351 of FIG. 3). It may include a power management circuit 452 (eg, the power management circuit 352 in FIG. 3), and a first transmission circuit 461 (eg, the first transmission circuit 361 in FIG. 3).

In one embodiment, the first transmission circuit 461 may include a first switch 4611 and a first transmission element (eg, the first transmission element 3612 in FIG. 3). For example, the first transmit element may include a power amplifier 4612, a duplexer 4613, an antenna 4614, and a low noise amplifier 4615. The antenna 4614 shown in FIG. 4 may be a separate and independent configuration that is arranged to be spaced apart from the antenna 297 in FIG. 2 .

In one embodiment, the first transmission circuit 461 may receive power from the first power management circuit 451 or the second power management circuit 452 depending on the connection state of the first switch 4611.

For example, the first transmission circuit 461 may receive power from the first power management circuit 451 to the first transmission and reception path 4511 based on the first connection. A processor (e.g., processor 220 in FIGS. 2 and 3) uses a transceiver (e.g., transceiver 270 in FIGS. 2 and 3), and the first switch 4611 is connected to the first power management circuit 451. A control signal to operate in the first connection state connected to can be transmitted to the first transmission circuit 461. Based on receiving the control signal, the first transmission circuit 461 may be electrically connected to the first power management circuit 451 through the first transmission and reception path 4511 using the first switch 4611.

For example, the first transmission circuit 461 may receive power from the second power management circuit 452 to the second transmission/reception path 4522 based on the second connection. The processor may use a transceiver to transmit a control signal that causes the first switch 4611 to operate in a second connection state connected to the second power management circuit 452 to the first transmission circuit 461. Based on receiving the control signal, the first transmission circuit 461 may be electrically connected to the second power management circuit 452 through the second transmission and reception path 4522 using the first switch 4611.

In one embodiment, the first power management circuit 451 may supply power to the first transmission circuit 461 through the first transmission/reception path 4511 based on the first connection. However, noise may occur during the power supply process and be transmitted to the receiving end of the first transmitting circuit 461. For example, the generated noise may be induced through the low noise amplifier 4615 through the noise path 440. In this case, as the reception performance of the first transmission circuit 461 deteriorates, a problem may occur in which the reception sensitivity of the electronic device itself deteriorates. Accordingly, the processor may perform the following operations to prevent degradation.

For example, based on the specified priority, the processor may identify whether the SNR of the received signal of the electronic device is less than a threshold as the first priority among a plurality of specified conditions associated with the communication performance of the electronic device as a specified condition. there is. In response to identifying the specified condition, the processor may measure RSRP and SNR for a specified time period. The processor identifies a first SNR and a second SNR corresponding to a first time point and a second time point, respectively, at which the measured RSRP has a first value during the specified time, and selects at least one of the first SNR and the second SNR. If is identified as being less than the threshold, it can be determined that the specified condition has been satisfied.

As an example, if the RSRP identified at a first time point during a specified time is -110dBm and the RSRP identified at a second time point is -110dBm, the processor may calculate the SNR at the first time point and the second time point. If the SNR at the first time point is 12dB and the SNR at the second time point is 7dB, the processor determines that the SNR at the second time point, 7dB, is identified as being less than a threshold (e.g., 10dB). It can be judged that it is satisfied. Accordingly, the processor may change the connection state of the first switch 4611 to replace the first power management circuit 451 supplying power to the first transmission circuit 461 with another power management circuit. For example, the processor may transmit a control signal to the first transmitting circuit 461 to change the operating state of the first switch 4611 set for establishment of the first connection to the operating state for establishing the second connection. there is. The processor may transmit the control signal to the transceiver and transmit it to the first switch 4611 through the transceiver. Accordingly, identifying the first power management circuit 451 that supplies power to the first transmission circuit 461 by the first connection, and using the transceiver, turning off the first connection and the second power management circuit 452 may transmit a control signal to the first switch 4611 to turn on the second connection for supplying power to the first transmission circuit 461. After changing the state of the first switch 4611 as described above, the first transmission circuit 461 can receive power from the second power management circuit 452 through the second transmission and reception path 4522.

According to one embodiment, an electronic device (e.g., the electronic devices 101 and 201 of FIGS. 1 and 2) includes a first power management circuit 451 (e.g., the power management circuit 351 of FIG. 3) and a second power management circuit 451 (e.g., the power management circuit 351 of FIG. 3). A power management circuit 452 (e.g., power management circuit 352 in Figure 3), a first transmission circuit 561 (e.g., first transmission circuits 361 and 461 in Figures 3 and 4), and at least one may include an antenna 597 (e.g., antenna 297 in FIG. 2).

In one embodiment, the first transmission circuit 561 may include a first switch 5611 and a first transmission element (eg, the first transmission element 3612 in FIG. 3).

It may include a third transmission circuit 369). The above description of FIG. 6 is an example, and the electronic device may further include at least one power management circuit and/or at least one transmission circuit.

According to one embodiment, the first transmission circuit 661 may include a first switch 6611 and a first transmission element 6612.

The description of the switch and transmission element can be replaced by the description of FIG. 3 described above.

In one embodiment, the plurality of power management circuits 651, 652, and 653 may each support different performance.

For example, the first power management circuit 651 may support wireless communication performed by envelope tracking (ET) based on the first bandwidth. For example, the first bandwidth may be a bandwidth corresponding to a wideband. As an example, the first power management circuit 651 may support wireless communication performed by average power tracking (APT). When the transmission power required by the transmission circuit to be supplied with power through the first power management circuit 651 is more than the threshold power, the electronic device uses the first power management circuit 651 to transmit power by ET based on the first bandwidth. Wireless communication can be performed. If the transmission power required by the transmission circuit to be supplied with power through the first power management circuit 651 is less than the threshold power, the electronic device can perform wireless communication by APT using the first power management circuit 651. there is.

For example, the second power management circuit 652 may support wireless communication performed by the ET based on the second bandwidth. For example, the second bandwidth may correspond to a lower bandwidth than the first bandwidth. As an example, the second power management circuit 652 may support wireless communication performed by APT. For example, when the transmission power required by the transmission circuit to be supplied with power through the second power management circuit 652 is more than the threshold power, the electronic device uses the second power management circuit 652 to Wireless communication by ET can be performed. For example, when the transmission power required by the transmission circuit to be supplied with power through the second power management circuit 652 is less than the threshold power, the electronic device uses the second power management circuit 652 to perform wireless communication by APT. It can be done. As another example, when the bandwidth allocated to wireless communication using the second power management circuit 652 is more than a threshold bandwidth (e.g., 60 MHz), the electronic device manages the second power even if the transmission power required by the transmission circuit is more than the threshold power. Using the circuit 652, wireless communication by APT can be performed based on the second bandwidth.

For example, the third power management circuit 653 may support wireless communication performed by average power tracking (APT). As an example, the third power management circuit 653 may support wireless communication by APT performed based on a third bandwidth that is lower than the second bandwidth. As another example, the third power management circuit 653 may support wireless communication without restrictions on allocated bandwidth.

The above-described bandwidth-related figures are illustrative, and embodiments of the present disclosure are not limited thereto.

In one embodiment, the processor may identify the first transmission power of the first transmission circuit 661 and the second transmission power of the second transmission circuit 662. For example, the first transmit power and the second transmit power may be less than the threshold power. In this case, the processor may determine a power management circuit to supply power to the first and second transmission circuits 661 and 662, respectively, based on criteria other than transmission power. For example, the processor may determine a power management circuit to supply power to the first transmission circuit 661 and the second transmission circuit 662 based on the reception sensitivity of the electronic device or the temperature of the power management circuit.

In one embodiment, the processor may identify the first transmission power of the first transmission circuit 661 and the second transmission power of the second transmission circuit 662. For example, the first transmission power and the second transmission power may be greater than or equal to the threshold power. In this case, the processor may determine a power management circuit to supply power to the first and second transmission circuits 661 and 662, respectively, taking into account the relationship between bandwidths in which the transmission circuits operate. For example, the processor may match the power management circuit to the transmit circuit based on whether the bandwidth for transmitting the signal is greater than or equal to a threshold bandwidth. For example, when the first bandwidth for signal transmission of the first transmission circuit 661 is greater than or equal to the threshold bandwidth and the second bandwidth for signal transmission of the second transmission circuit 662 is less than the threshold bandwidth, the processor transmits the first transmission circuit 662. The first power management circuit 651 may be assigned to the circuit 661 and the second power management circuit 652 may be assigned to the second transmission circuit 662. As another example, when the first bandwidth and the second bandwidth for signal transmission of the first transmission circuit 661 and the second transmission circuit 662 are both equal to or greater than the threshold bandwidth, the first transmission circuit 661 is set as having high priority. The first power management circuit 651 may be allocated to and the second power management circuit 652 may be allocated to the second transmission circuit 662.

In one embodiment, the processor may identify the first transmission power of the first transmission circuit 661 and the second transmission power of the second transmission circuit 662. For example, the first transmit power may be greater than the second transmit power. For example, the first transmission power may be above the threshold power, and the second transmission power may be below the threshold power. For example, the first transmission power and the second transmission power may be the maximum transmission power supported by the first transmission circuit 661 and the second transmission circuit 662, respectively. In this case, the processor may control the first switch 6611 to turn on the first connection between the first power management circuit 651 and the first transmission circuit 661. For example, the processor may control the second switch 6621 so that the second transmission circuit 662 is connected to one of the second power management circuit 652 and the third power management circuit 653. In one embodiment, the processor may control the second switch 6621 to receive power from the second power management circuit 652 when the second transmit circuit 662 is identified as operating based on ET. . In one embodiment, if the second transmit circuit 662 is identified as operating based on APT, the processor may control the second switch 6621 to receive power from the third power management circuit 653. .

Circuit 351) can be identified. For example, the electronic device may identify that the first switch included in the first transmission circuit operates while connected to the first transmission and reception path (e.g., the first transmission and reception path 4511 of FIG. 4).

For example, the electronic device may identify the current connection state and then change the connection state. In one example, the electronic device sends a control signal to the first control signal to turn off the first connection between the first power management circuit and the first transmission circuit and to turn on the second connection between the second power management circuit and the first transmission circuit. It can be transmitted to a switch (e.g., the first switch 3611 in FIG. 3).

In operation 815, the electronic device may identify the first SNR and the second SNR corresponding to the first and second time points, respectively, at which the measured RSRP has the first value.

For example, when the RSRP measured at the first time point and the second time point are both -110 dBm, the electronic device may identify the first SNR measured at the first time point and the second SNR measured at the second time point.

In operation 820, the electronic device may determine whether at least one of the first SNR and the second SNR is less than a threshold.

For example, the electronic device may identify that the first SNR is 12 dB and the second SNR is 8 dB. At this time, the electronic device can identify that the second SNR is less than 10dB set as the threshold. Accordingly, the electronic device can determine that the specified condition is satisfied.

For example, the electronic device may select a low audible noise among the first power management circuit and the power management circuit based on the occurrence frequency, occurrence probability, and/or occurrence history of noise (or noise) corresponding to the audible frequency band. A predefined second power management circuit can be identified.

For example, the electronic device may identify the communication performance and/or supported bandwidth of each of the first power management circuit and the second power management circuit.

In operation 1015, the electronic device may turn on the second connection between the first transmission circuit and the second power management circuit that is predefined as having low audible noise.

In response to the control signal being transmitted, the second transmission circuit may receive power from the first power circuit.

In operation 1005, if both the first transmission circuit and the second transmission circuit are not operating based on CDRX (e.g., operation 1005-No), the electronic device may perform operation 1025. For example, when only one of the first transmission circuit or the second transmission circuit is operating based on CDRX, the electronic device may perform operation 1025. For example, when neither the first transmission circuit nor the second transmission circuit is operating based on CDRX, the electronic device may perform operation 920 of FIG. 9 .

At operation 1105, the electronic device may establish communication with the base station. The description of operation 1105 may be replaced with the description of operation 705 described above.

In operation 1110, when an antenna (e.g., antenna 297 in FIG. 2) operates, the electronic device can identify whether the SNR is less than a threshold using a specified condition.

For example, an antenna identified as operational may be a separate, independent configuration positioned separately from the plurality of transmit circuits and the plurality of power management circuits. For example, an antenna identified as operational may be a UWB antenna. For example, the antenna 297 may be connected to a UWB communication module and may not be electrically connected to a transmitting element (e.g., the transmitting element 262 of FIG. 2).

In operation 1120, if it is identified that at least some of the measured SNRs are not less than (e.g., operation 1120-No), the electronic device may perform operation 1110. For example, if all measured SNRs are identified as being equal to or greater than the threshold, the electronic device may perform operation 1110. The electronic device may determine that there is no problem with the reception sensitivity of the antenna and perform operation 1110.

For example, the electronic device may generate the control signal using a processor and transmit the generated control signal to the first switch using a transceiver. In response to the control signal being transmitted, the first transmission circuit may receive power from the second power circuit.

For example, the first separation distance between the antenna and the first transmission/reception path between the first power management circuit and the first transmission circuit (e.g., the first separation distance L1 in FIG. 5) is the distance between the second power management circuit and the first transmission circuit. It may be shorter than the second separation distance between the antenna and the second transmission/reception path between the transmission circuits (eg, the second separation distance L2 in FIG. 5). For example, the separation distance between the first power management circuit and the antenna may be shorter than the separation distance between the second power management circuit and the antenna. The electronic device may determine that noise generated while the first power management circuit supplies power to the first transmission circuit has more influence on the antenna. Accordingly, the electronic device can switch the connection state such that the second power management circuit supplies power to the first transmission circuit.

In operation 1220, if it is identified that the electronic device is not communicating with the base station based on the SA operation status (e.g., operation 1220 - No), the electronic device may perform operation 1230. For example, if the electronic device is identified as communicating with the base station based on the NSA operating state or the CA operating state, the electronic device may perform operation 1230.

In operation 1225, the electronic device may control the first switch to maintain the second connection.

For example, based on the second connection, the electronic device may control the first switch to maintain a state in which the first transmission circuit receives power from the second power management circuit through the second transmission and reception path.

For example, an electronic device may measure temperature using sensors included in each of a plurality of power management circuits.

For example, an electronic device may measure temperature using sensors disposed in an area adjacent to a plurality of power management circuits.

For example, the electronic device can identify the first temperature of the first power management circuit and the second temperature of the second power management circuit.

In operation 1315, the electronic device can identify whether the second temperature is higher than the first temperature.

In operation 1315, if the second temperature is identified as being higher than the first temperature (e.g., operation 1315 - Yes), the electronic device may perform operation 1320.

In operation 1315, if the second temperature is not identified as being higher than the first temperature (e.g., operation 1315 - No), the electronic device may perform operation 1310.

For example, the electronic device can identify the first transmission power of the first transmission circuit and the second transmission power of the second transmission circuit.

In operation 1410, the electronic device may determine whether the first transmission power is greater than the second transmission power.

In operation 1410, if the first transmission power is identified as being greater than the second transmission power (e.g., operation 1410 - Yes), the electronic device may perform operation 1415.

In operation 1410, if the first transmission power is identified as being less than or equal to the second transmission power (e.g., operation 1410 - No), the electronic device may perform operation 1405.

In operation 1415, the electronic device may control the first switch to turn on the first connection.

For example, the electronic device may map the first power management circuit (e.g., the first power management circuit 651 of FIG. 6) with the largest supported bandwidth among the plurality of power management circuits with the first transmission circuit. .

For example, the first power management circuit 651 may support wireless communication performed by ET based on the first bandwidth. For example, the first bandwidth may be a bandwidth corresponding to a wideband. For example, in a specific situation, when the bandwidth of the frequency required for wireless communication using the first transmission circuit is 60 MHz or more, the first power management circuit may be used. However, the figures regarding bandwidth are illustrative and embodiments of the present disclosure are not limited thereto.

In operation 1420, the electronic device determines whether the second transmit circuit is configured to include a second power management circuit (e.g., the second power management circuit 652 of FIG. 6) or a third power management circuit (e.g., the third power management circuit (e.g., the third power management circuit of FIG. 6). The second switch can be controlled to be connected to one of 653)).

For example, the second power management circuit may support wireless communication performed by the ET based on the second bandwidth. For example, the second bandwidth may correspond to a lower bandwidth than the first bandwidth.

For example, the third power management circuit may support wireless communication performed by the APT based on the third bandwidth. For example, the third bandwidth may correspond to a lower bandwidth than the second bandwidth.

For example, the electronic device identifies the power required to perform wireless communication using the second transmission circuit, and transmits the second power management circuit or the third power management circuit based on the magnitude relationship of the identified power. It can be selectively connected using a circuit and a second switch.

For example, the electronic device identifies the type of wireless communication using the second transmission circuit, and based on the identified type, configures the second power management circuit or the third power management circuit using the second transmission circuit and the second switch. Can be connected optionally. For example, when ET-based communication is required, the second switch can be controlled so that the second transmission circuit is connected to the second power management. For example, when APT-based communication is required, the second switch can be controlled so that the second transmission circuit is connected to the third power management circuit. For example, even when APT-based communication is required, the second switch may be controlled so that the second transmission circuit and the second power management circuit are connected.

15 is a flowchart of an operation of an electronic device, according to an embodiment.

In operation 1505, the electronic device may identify the transmission power of at least some of the plurality of transmission circuits (e.g., the plurality of transmission circuits 661, 662,?, 669 of FIG. 6).

For example, the electronic device may identify the transmission power of at least some of the plurality of transmission circuits in order to allocate (or select) a power management circuit for supplying power.

In operation 1510, the electronic device transmits the first transmission power of the first transmission circuit (e.g., the first transmission circuit 661 of FIG. 6) and the second transmission circuit (e.g., the second transmission circuit 662 of FIG. 6). It is possible to identify whether the second transmission power of is greater than or equal to the threshold power.

For example, the electronic device may identify the first transmission power of the first transmission circuit and the second transmission power of the second transmission circuit among the transmission powers identified in operation 1505.

For example, the electronic device may identify whether the identified first and second transmission powers are equal to or greater than the threshold power. As an example, the threshold power may be a preset setting value or a setting value that can be changed by the user.

In operation 1510, if the first transmission power and the second transmission power are identified as being equal to or greater than the threshold power (e.g., operation 1510 - Yes), the electronic device may perform operation 1515.

In operation 1515, the electronic device may identify bandwidths in which the first and second transmission circuits operate, respectively.

For example, when both the first transmission power and the second transmission power are equal to or greater than the threshold power, the electronic device may supply power to the first transmission circuit and the second transmission circuit in consideration of the size relationship of the bandwidth in which each transmission circuit operates. Each power management circuit can be determined.

In operation 1520, the electronic device may allocate different power management circuits to the first transmission circuit and the second transmission circuit based on the size relationship of the identified bandwidths. For example, the electronic device may match the power management circuit to the transmission circuit based on whether the bandwidth for transmitting signals of the transmission circuits is greater than or equal to a threshold bandwidth.

For example, the electronic device may match the first power management circuit and the second power management circuit to the transmission circuit, respectively. As an example, the first power management circuit may support wireless communication performed by envelope tracking (ET) based on the first bandwidth. The first bandwidth may be a bandwidth corresponding to a wideband. As an example, the second power management circuit may support wireless communication performed by the ET based on the second bandwidth. The second bandwidth may correspond to a lower bandwidth than the first bandwidth.

For example, when the first bandwidth for signal transmission of the first transmission circuit is greater than or equal to the threshold bandwidth and the second bandwidth for signal transmission of the second transmission circuit is less than the threshold bandwidth, the electronic device may transmit the first signal to the first transmission circuit. A power management circuit (e.g., the first power management circuit 651 in FIG. 6) can be assigned and a second power management circuit (e.g., the second power management circuit 652 in FIG. 6) can be assigned to the second transmission circuit. there is.

For example, if the first bandwidth and the second bandwidth for signal transmission of the first transmission circuit and the second transmission circuit are both greater than or equal to the threshold bandwidth, the first power management circuit is assigned to the first transmission circuit set as high priority. And the second power management circuit can be assigned to the second transmission circuit.

In operation 1510, if the first transmission power and the second transmission power are identified as being less than the threshold power (e.g., operation 1510 - No), the electronic device may perform operation 1525.

In operation 1525, the electronic device may determine a power management circuit to supply power to the first and second transmission circuits, respectively, based on criteria other than transmission power.

For example, the electronic device may determine a power management circuit to supply power to the first and second transmission circuits, respectively, based on the reception sensitivity of the electronic device or the temperature of the power management circuit. Operations related to determining the power management circuit based on the reception sensitivity of the electronic device and the temperature of the power management circuit may be replaced with the description of FIG. 2 described above.

The size of the driving voltage supplied to the transmission circuit to perform wireless communication may vary depending on the strength of the wireless signal transmitted by the electronic device. For example, the driving voltage supplied to the PA may change depending on the communication situation of the electronic device. As an example, the supplied driving voltage may affect the channel status, communication quality, and communication mode (e.g., stand-alone (SA), non-standalone (NSA), or carrier aggregation (CA)) between the electronic device and an external device (e.g., a base station). ) may change depending on the conditions.

An electronic device may include a plurality of power management circuits and a plurality of transmission circuits with different performances. The electronic device can supply power to the transmission circuit by determining the optimal power management circuit according to the above-described change in the situation of the electronic device. However, after the electronic device determines the first power management circuit for power supply, it is difficult to switch to supply power to the second power management circuit during wireless communication. For example, if a decrease in communication quality is identified during wireless communication after supplying power using a power management circuit, switching to supply power to the transmitting circuit through a different power management circuit to reduce quality degradation. It is difficult to do so.

For example, communication quality may be degraded due to noise components generated while the power management circuit is running.

For example, a capacitor that is charged or discharged depending on the level of the supply voltage may be disposed at the output terminal of the power management circuit. In this case, physical shaking of the capacitor and the board on which the capacitor is mounted may occur due to charging and discharging of the capacitor. There is a problem that communication quality deteriorates due to noise in the audible frequency band due to tremor.

As an example, the power supplied by the power management circuit acts as noise on components related to signal reception (e.g., low-noise amplifier (LNA)), resulting in deterioration of reception sensitivity (e.g., signal-noise ratio (SNR)). There is.

For example, noise components (e.g., harmonic) generated from a power amplifier may affect components (e.g., ultra-wideband (UWB) antenna) disposed outside the transmission circuit and provided for signal reception. As the components experience performance degradation due to noise components, the communication quality of the electronic device may deteriorate.

In addition to the problems described above, if a physical defect (eg, failure or malfunction) occurs in a power management circuit operating for wireless communication, it may be difficult to quickly supply power through another power management circuit. Additionally, the power management circuit may have performance degradation due to heat generation issues during operation.
