For example, the RFFE 160 may include a coupler 170 connected to the antenna 190. For example, the coupler 170 may be used to obtain a coupled signal that is part of a signal transmitted through the antenna 190. For example, the RFFE 160 may include a power amplifier (PA) 161 connected to the coupler 170. For example, in this document, “the first component and the second component are connected” means not only the first component and the second component are directly connected, but also the first component and the second component are connected. It can indicate that two components are connected through a third component. For example, the PA 161 may be connected to the coupler 170 through the duplexer 180. For example, the RFFE 160 may include a duplexer 180 between the PA 161 and the coupler 170.

For example, PA 161 may be used to set the transmission power of a signal transmitted through antenna 190. For example, the duplexer 180 may be used to distinguish between a signal transmitted through the antenna 190 and a signal received through the antenna 190.

For example, the RFFE 160 may further include a low noise amplifier (LNA) 175. For example, LNA 175 may be used to amplify the power of a signal received through antenna 190.

For example, the RFIC 130 may include a transmit (Tx) chain 135. For example, the RFIC 130 may include a local oscillator (LO) 140. For example, the Tx chain 135 may include a mixer 136 connected to the LO 140. For example, a signal provided from the processor 120 may be up-converted through the mixer 136 connected to the LO 140. For example, the up-converted signal may be provided to the RFFE 160.

For example, the RFIC 130 may include a receive (Rx) chain 145. For example, the Rx chain 145 may include a mixer 146 connected to the LO 140. For example, a signal provided from RFFE 160 may be down-converted through mixer 146 coupled to LO 140. For example, the down-converted signal may be provided to the processor 120.

For example, the first switch 150 includes a first terminal 150-1 connected to the Tx chain 135, a second terminal 150-2 connected to the PA 161, and a second switch 155. It may include a third terminal (150-3) connected to the third terminal (155-3).

For example, the RFIC 130 may include a second switch 155. For example, the second switch 155 may be used to electrically connect the coupler 170 or the Tx chain 135 to the Rx chain 145. For example, the second switch 155 includes a first terminal 155-1 connected to the Rx chain 145, a second terminal 155-2 connected to the coupler 170, and the first switch 150. It may include a third terminal (155-3) connected to the third terminal (150-3).

For example, the RFIC 130 may include a mixer 159 coupled to the LO 199. For example, the signal provided from RFFE 160 may be down-converted through mixer 159 coupled to LO 199. For example, the down-converted signal may be provided to the processor 120. For example, the Rx chain 158, unlike the Rx chain 145 used to obtain the coupling signal 192 of the first signal 191, which will be illustrated below, has an antenna 190 and an LNA 175. ) can be used to obtain a signal received through.

Each of the Tx chain 135, Rx chain 145, and Rx chain 158 can be illustrated through FIG. 2.

2 shows examples of a transmit (Tx) chain and a receive (Rx) chain.

Referring to FIG. 2, the Tx chain 135 may further include a digital to analog converter (DAC) 201 and a PA (202). For example, the DAC 201 can be used to convert a digital signal input to the DAC 201 into an analog signal. For example, the mixer 136 connected to the LO 140 may be used to up-convert a signal input to the mixer 136. For example, the PA 202 may be used to amplify a signal input to the PA 202.

The Rx chain 145 may further include an analog to digital converter (ADC) 203 and a PA (204). For example, the PA 204 may be used to amplify a signal input to the PA 204. For example, the mixer 146 connected to the LO 140 may be used to down-convert a signal input to the mixer 146. For example, the ADC 203 can be used to convert an analog signal input to the ADC 203 into a digital signal.

Rx chain 158 may further include ADC 205 and PA 206. For example, the PA 206 can be used to amplify a signal input to the PA 206. For example, the mixer 159 connected to the LO 199 may be used to down-convert a signal input to the mixer 159. For example, the ADC 205 may be used to convert an analog signal input to the ADC 205 into a digital signal.

Referring again to FIG. 1, RFFE 160 may include a switch that replaces duplexer 180. The switch can be illustrated through FIG. 3.

Figure 3 shows an example of a switch included within an RFFE.

Referring to FIG. 3, the RFFE 160 may include a switch 300 instead of the duplexer 180. For example, when the RFFE 160 is an RFFE for frequency division duplex (FDD), the RFFE 160 may include a duplexer 180. For example, when the RFFE 160 is an RFFE for time division duplex (TDD), the RFFE 160 may include the switch 300. For example, the switch 300 has a first terminal 301 connected to the PA 161, a second terminal 302 connected to the LNA 175, and a third terminal 303 connected to the coupler 170. It can be included. For example, the switch 300 is in a first state 304 that electrically connects the first terminal 301 and the third terminal 303 within time resources for transmitting a signal through the antenna 190. It can be within. For example, the switch 300 is in a second state 305 that electrically connects the second terminal 302 and the third terminal 303 within time resources for receiving a signal through the antenna 190. It can be within.

Referring back to FIG. 1 , in one embodiment, processor 120 performs operations to identify the state of at least a portion of RFIC 130 and at least a portion of RFFE 160, including: first switch 150 and/or Alternatively, it can be executed based on the control of the second switch 155.

For example, the processor 120 electrically connects the PA 161 and the Tx chain 135 through the first switch 150 and connects the coupler 170 and the Rx chain 145 through the second switch 155. ) Based on electrically connecting the first signal 191 obtained through the Tx chain 135, the power set using the PA 161 is transmitted through the antenna 190, and the first signal 191 is transmitted through the antenna 190. The coupling signal 192 of (191) can be obtained through the Rx chain 145. For example, the first signal 191 may be transmitted to an external electronic device through the antenna 190. For example, the coupling signal 192 of the first signal 191 may be a part of the first signal 191 transmitted through the antenna 190. For example, the connection between the PA 161 and the Tx chain 135 includes the second terminal 150-2 of the first switch 150 and the third terminal 150-3 of the first switch 150. ), the state 151 of the first switch 150 electrically connecting the second terminal 150-2 of the first switch 150 to the first terminal 150-1 of the first switch 150. can be formed through For example, the connection between the coupler 170 and the Rx chain 145 is connected to the second terminal 155-2 of the second switch 155 and the third terminal 155-3 of the second switch 155. ), the state 156 of the second switch 155 electrically connecting the second terminal 155-2 of the second switch 155 to the first terminal 155-1 of the second switch 155. can be formed through

For example, the processor 120 is electrically disconnected from the Tx chain 135 and the coupler 170, which are electrically disconnected from the PA 161 through the first switch 150 and the second switch 155. Based on connecting the disconnected Rx chain 145, the second signal 193 obtained through the Tx chain 135 can be obtained through the Rx chain.

For example, processor 120 electrically disconnects Tx chain 135 from PA 161 based on changing the state of first switch 150 from state 151 to state 152, Electrically disconnects the Rx chain 145 from the coupler 170 based on changing the state of the second switch 155 from state 156 to state 157, and electrically disconnects the first switch 150 in state 152. ) and the second switch 155 in the state 157, the Tx chain 135 and the Rx chain 145 can be electrically connected. For example, the electrical connection between the Tx chain 135 and the Rx chain 145 is connected to the second terminal 150-2 of the first switch 150 and the third terminal 150 of the first switch 150. Among -3), the state 152 of the first switch 150 connecting the third terminal 150-3 of the first switch 150 with the first terminal 150-1 of the first switch 150, and Among the second terminal 155-2 of the second switch 155 and the third terminal 155-3 of the second switch 155, the third terminal 155-3 of the second switch 155 is connected to the second terminal 155-3 of the second switch 155. It can be formed through the state 157 of the second switch 155 connected to the first terminal 155-1 of the switch 155.

For example, the processor 120 determines the state of the RFFE 160 and the state of the RFIC 130 based at least in part on the coupling signal 192 and the second signal 193 of the first signal 191. can be identified.

For example, since the coupling signal 192 of the first signal 191 is the part of the first signal 191 transmitted via the Tx chain 135 and the PA 161, the first signal 191 ) of the coupling signal 192 may indicate the status of the transmission path of the first signal 191 and the reception path of the coupling signal 192 of the first signal 191. For example, the coupling signal 192 of the first signal 191 may indicate the state of the Tx chain 135 and the state of the PA 161. For example, the coupling signal 192 of the first signal 191 indicates the state of the Tx chain 135 and the state of the PA 161, meaning that the coupling signal 192 of the first signal 191 It may indicate that can be used to obtain information about the state of the Tx chain 135 and the state of the PA 161. For example, the coupling signal 192 of the first signal 191 may indicate the state of the Rx chain 145. For example, that the coupling signal 192 of the first signal 191 indicates the state of the Rx chain 145 means that the coupling signal 192 of the first signal 191 indicates the state of the Rx chain 145. It may indicate that it can be used to obtain information about the state.

For example, since the second signal 193 is generated through the Tx chain 135 and acquired through the Rx chain 145, the second signal 193 is one of the RFIC 130 and the RFFE 160. The status of the RFIC 130 may be indicated. For example, since the second signal 193 does not pass through the RFFE 160, the second signal 193 is the state of the Tx chain 135 among the states of the Tx chain 135 and the state of the PA 161. can represent. For example, since the second signal 193 does not pass through the RFFE 160, the second signal 193 may indicate the state of the Rx chain 145.

For example, the coupling signal 192 of the first signal 191 represents both the state of the Tx chain 135 and the state of the PA 161, and the second signal 193 represents the state of the Tx chain 135 and the PA ( 161), since it indicates only the state of the Tx chain 135, the processor 120 determines the state of the RFFE 160 based on the coupling signal 192 and the second signal 193 of the first signal 191. The status and status of the RFIC 130 can be identified.

For example, the processor 120 may determine the state of the Tx chain 135 (or the transmission and transmission of the first signal 191) based on the coupling signal 192 of the first signal 191 in the first reference state. the state of at least a portion of the RFIC 130 associated with the reception of the coupling signal 192 of the first signal 191) and the state of the PA 161 (or the RFFE 160 associated with the transmission of the first signal 191) It can be identified that at least a portion of the state) is in a normal operating state. For example, the coupling signal 192 of the first signal 191 in the first reference state is transmitted through the antenna 190 at a targeted transmission power on a frequency where the first signal 191 is targeted. It can indicate that it has been sent. The coupling signal 192 of the first signal 191 in the first reference state will be illustrated through the description of FIG. 6. For example, the Tx chain 135 and PA 161 in the normal operating state transmit a signal through the antenna 190 at a target transmission power on a target frequency. It can indicate that you are in a state where you can do it.

For example, the processor 120 determines the state of the Tx chain 135 (or the first signal 191) based on the coupling signal 192 of the first signal 191 in a state different from the first reference state. ) and the state of at least a portion of the RFIC 130 associated with the transmission of the coupling signal 192 of the first signal 191 ) and/or the state of the PA 161 (or the transmission of the first signal 191 It may be identified that the state of at least a portion of the RFFE 160 (related to) is different from the normal operating state. For example, the coupling signal 192 of the first signal 191 in a state different from the first reference state is transmitted through the antenna 190 on a frequency distinct from the target frequency of the first signal 191. Or, the first signal 191 is transmitted through the antenna 190 with a transmission power that is different from the target transmission power, or the first signal 191 is transmitted on a frequency that is different from the target frequency and is different from the target transmission power. Transmission power may indicate that it is transmitted through the antenna 190. The coupling signal 192 of the first signal 191 in a state different from the first reference state will be illustrated through the description of FIG. 6. For example, the Tx chain 135 in a state other than the normal operating state (e.g., malfunctioning state or abnormal operating state) is in a state in which the Tx chain 135 identifies or provides a frequency that is distinct from the target frequency. can indicate. For example, if the Tx chain 135 acquires a signal on a frequency distinct from the target frequency and transmits the signal to the PA 161, damage to the PA 161 may occur. For example, Tx chain 135 in a state other than the normal operating state may indicate that Tx chain 135 is in a state that may cause damage to PA 161. For example, PA 161 in a state different from the normal operating state may indicate that PA 161 is in a state that sets a transmit power that is distinct from the desired transmit power.

For example, the processor 120 may identify that the state of the Tx chain 135 is the normal operating state based on the second signal 193 in the second reference state. For example, the second signal 193 in the second reference state may represent a desired (or required) state associated with transmission of the first signal 191. For example, the second signal 193 in the second reference state may indicate that the state of the Tx chain 135 is the normal operating state. For example, because the second signal 193 does not pass through the RFFE 160, the processor 120 determines the state of the Tx chain 135 based on the second signal 193 in the second reference state. It can be identified that is in the normal operating state.

For example, the processor 120 may identify that the state of the Tx chain 135 is different from the normal operating state based on the second signal 193 in a state different from the second reference state. For example, since the second signal 193 does not pass through the RFFE 160, the processor 120 operates the Tx chain 135 based on the second signal 193 in a state different from the second reference state. ) can be identified that the state is different from the normal operating state.

For example, the processor 120, based on the coupling signal 192 of the first signal 191 in a state different from the first reference state and the second signal 193 in the second reference state, It may be identified that the state of at least a portion of the RFFE 160 associated with the transmission of the 1 signal 191 is different from the normal operating state.

For example, the processor 120 is based on the coupling signal 192 of the first signal 191 in a state different from the first reference state and the second signal 193 in a state different from the second reference state. Thus, it can be identified that the state of at least a portion of the RFIC 130 related to transmitting the first signal 191 and acquiring the second signal 193 is different from the normal operating state. For example, the processor 120 is based on the coupling signal 192 of the first signal 191 in a state different from the first reference state and the second signal 193 in a state different from the second reference state. Thus, it can be identified that the state of at least part of the RFIC 130 and/or the state of the at least part of the RFFE 160 is different from the normal operating state.

For example, the electronic device 101 may operate the third terminal 150- 3) and the third terminal 155-3 of the second switch 155 may further include an attenuator. The attenuator can be illustrated through FIG. 4.

Figure 4 shows an example of an attenuator.

Referring to FIG. 4, the RFIC 130 is within the connection path between the third terminal 150-3 of the first switch 150 and the third terminal 155-3 of the second switch 155, It may include an attenuator 400. For example, the processor 120 operates the attenuator 400 based on electrically connecting the Tx chain 135 and the Rx chain 145 through the first switch 150 and the second switch 155. Through this, the second signal 193 with reduced power can be obtained through the Rx chain 145. For example, the reduced power may be identified under the control of processor 120. For example, the second signal 193 passing through the attenuator 400 may reduce damage to the Rx chain 145 due to the intensity of the second signal 193.

Figure 4 shows an example in which the attenuator 400 includes a variable resistor, but this is for convenience of explanation. For example, the attenuator 400 may include a field effect transistor (FET), a resistor, an inductor, a capacitor, and/or bias ports. However, it is not limited to this.

For example, obtaining the coupling signal 192 of the first signal 191 and obtaining the second signal 193 may be implemented in various ways.

For example, the processor 120 may obtain the second signal 193 after acquiring the coupling signal 192 of the first signal 191. Obtaining the second signal 193 based on acquiring the coupling signal 192 of the first signal 191 can be illustrated through FIG. 5 .

For example, the information is based on identifying the adjacent channel power ratio (ACPR), adjacent channel leakage ratio (ACLR), or error vector magnitude (EVM) of the coupling signal 192 of the first signal 191. Thus, it can be obtained. For example, the reference information may be a parameter used to identify the state of the coupling signal 192 of the first signal 191. For example, the reference information may correspond to a threshold value, which will be illustrated through the description of FIG. 6. For example, the processor 120 may identify whether the state of the coupling signal 192 of the first signal 191 is the first reference state, based on the difference between the reference information and the information. You can. The state of the coupling signal 192 of the first signal 191 can be illustrated through FIG. 6.

Figure 6 shows an example of the state of the coupling signal of the first signal.

Referring to FIG. 6, the horizontal axes of each of the charts 600 and 630 represent frequencies, and the vertical axes of each of the charts 600 and 630 represent the coupling signal 192 of the first signal 191. ) indicates the intensity of. For example, the range 610 of each of the charts 600 and 630 is the target frequency range (or demand (or) of the first signal 191 (or the coupling signal 192 of the first signal 191). required) frequency range), and the ranges 620 and 625 of the charts 600 and 630, respectively, represent frequency ranges outside the target frequency range. For example, the processor 120 determines the strength of the coupling signal 192 of the first signal 191 within range 610 and the strength of the coupling signal 192 within range 620 and range 625, as shown in chart 600. Based on identifying that the difference value 615 between the intensity of the coupling signal 192 of the first signal 191 at is greater than or equal to a threshold, the coupling signal 192 of the first signal 191 The state may be identified as the first reference state. For example, the processor 120 may determine the state of the coupling signal 192 of the first signal 191 based on identifying that the difference value 615 is below the threshold, as shown in chart 630. It can be identified that is different from the first reference state. However, it is not limited to this.

It can be identified that the state of the ring signal 192 is different from the first reference state. However, it is not limited to this.

Referring again to FIG. 5, the processor 120 executes operation 505 based on the coupling signal 192 of the first signal 191, which is the first reference state, and enters a state different from the first reference state. Operation 507 may be performed based on the coupling signal 192 of the first signal 191.

In operation 505, the processor 120 connects the PA 161 and the Tx through the first switch 150 under the condition that the state of the coupling signal 192 of the first signal 191 is the first reference state. It is possible to maintain the chain 135 electrically connected and the coupler 170 and the Rx chain 145 through the second switch 155. For example, the state of the coupling signal 192 of the first signal 191 is the first reference state, at least a portion of the RFIC 130 used for the transmission of the first signal 191 and Since at least a portion of the RFFE 160 indicates the normal operating state, the processor 120 connects the PA 161 through the first switch 150 for transmission of a signal following the first signal 191. It is possible to maintain the Tx chain 135 electrically connected and the coupler 170 and the Rx chain 145 through the second switch 155 . For example, the processor 120 electrically disconnects the Tx chain 135 from the PA 161 through the first switch 150 and disconnects the Rx chain from the coupler 170 through the second switch 155. It is possible to refrain from electrically disconnecting 145 and electrically connecting Tx chain 135 and Rx chain 145 through first switch 150 and second switch 155. there is.

The Tx chain 135 and Rx chain 140 can be electrically connected. For example, the state of the coupling signal 192 of the first signal 191 is different from the first reference state because the at least part of the RFIC 130 and/or the at least part of the RFFE 160 Because the state indicates a difference from the normal operating state, the processor 120 may select a component among the at least a portion of the RFIC 130 and the at least a portion of the RFFE 160 to operate in a state different from the normal operating state ( Example: electrically disconnecting the Tx chain 135 from the PA 161 via the first switch 150 to identify the at least a portion of the RFIC 130 and/or the at least a portion of the RFFE 160; , electrically disconnect the Rx chain 140 from the coupler 170 through the second switch 155, and connect the Tx chain 135 and the Rx chain 140 through the first switch 150 and the second switch 155. ), the RFFE 160 can be electrically separated from each of the Tx chain 135 and Rx chain 145 in the RFIC 130.

Although not shown in FIG. 5 , the processor 120 determines, based on the second signal 193, that the state of at least a portion of the RFIC 130 associated with the transmission of the first signal 191 is the normal operating state. It is possible to determine whether it is recognized or not.

As described above, the electronic device 101 may obtain the second signal 193 according to the state of the coupling signal 192 of the first signal 191. For example, the electronic device 101 obtains the second signal 193 in response to the coupling signal 192 of the first signal 191 that is different from the first reference state, and ), it is possible to identify whether the state of at least part of the RFIC 130 related to the transmission of the first signal 191 is the normal operating state. For example, the electronic device 101 may include a component related to the transmission of the first signal 191 that malfunctions based on the coupling signal 192 and the second signal 193 of the first signal 191. is the at least part of the RFIC 130 associated with the transmission of the first signal 191 or the at least part of the RFFE 160 associated with the transmission of the signal 191.

Obtaining the coupling signal 192 of the first signal 191 after acquiring the second signal 193 can be illustrated through FIG. 7 .

7 is a flow diagram illustrating an example method of obtaining a coupling signal of a first signal based on acquiring a second signal.

Referring to FIG. 7 , in operation 701, the processor 120 may obtain the second signal 193. For example, the processor 120 may obtain the second signal 193 using the first switch 150 in state 152 and the second switch 155 in state 157. For example, operation 701 may be performed prior to transmission of the first signal 191. For example, the processor 120 may obtain the second signal 193 within second time resources within the slot preceding the first time resources within the slot transmitting the first signal 191. . However, it is not limited to this. For example, the processor 120 may acquire the second signal 193 in another slot before the slot transmitting the first signal 191.

At operation 702, processor 120 may identify whether second signal 193 is within the second reference state, based at least in part on obtaining second signal 193. For example, processor 120 executes operation 703 in response to a second signal 193 in the second reference state and in response to a second signal 193 in a state different from the second reference state. Operation 705 may be executed.

At operation 703, the processor 120 obtains a coupling signal 192 of the first signal 191 by transmitting the first signal 191 in response to the second signal 193 in the second reference state. can do. For example, processor 120, in response to second signal 193 in the second reference state, changes the state of first switch 150 from state 152 to state 151 and switches the second switch 150 to state 151. Based on changing the state of 155 from state 157 to state 156, the first signal 191 can be transmitted. The processor 120 may obtain the coupling signal 192 of the first signal 191 based on the transmission of the first signal 191. The processor 120 may identify whether the coupling signal 192 of the first signal 191 is within the first reference state.

At operation 705, the processor 120 may stop transmitting the first signal 191 in response to the second signal 193 being in a state different from the second reference state. For example, the processor 120 may bypass or defer transmitting the first signal 191 in response to the second signal 193 being in a state different from the second reference state. , you can avoid it. For example, the processor 120 resets at least a portion of the RFIC 130 used to obtain the second signal 193 based on the second signal 193 being in a state different from the second reference state. Alternatively, use of at least part of the RFIC 130 may be stopped or postponed for a set time. For example, processor 120 may, in response to a second signal 193 in the state being different from the second reference state, stop transmitting the first signal 191 and transmit the second signal 193. At least a portion of the RFIC 130 (e.g., the Tx chain 135 and/or the Rx chain 145) used for acquisition may be reset. For example, processor 120 may, in response to a second signal 193 in the state different from the second reference state, stop transmitting the first signal 191 and The use of some (e.g., Tx chain 135 and/or Rx chain 145) may be suspended or postponed for a predetermined period of time. For example, the processor 120 may perform the transmission of the first signal 191 using other components (not shown in FIG. 1) within the electronic device 101. However, it is not limited to this.

As described above, the electronic device 101 acquires the second signal 193 and then identifies whether to transmit the first signal 191 based on the second signal 193, thereby transmitting the first signal 193. Damage to at least part of the RFIC 130 related to the transmission of 191 or damage to at least part of the RFFE 160 due to malfunction of the at least part of the RFIC 130 can be reduced.

Referring back to FIG. 1 , in one embodiment, processor 120 switches first switch 150 and second switch 155 in response to obtaining coupling signal 192 of first signal 191. The second signal 193 can be obtained based on electrically connecting the Tx chain 135 and the Rx chain 145. For example, the processor 120 may couple the first signal 191 independently from whether the state of the coupling signal 192 of the first signal 191 is the first reference state. The second signal 193 may be acquired immediately after acquiring the ring signal 192. For example, acquiring the second signal 193 may be performed based on a set cycle. For example, acquiring the second signal 193 may be initiated and performed periodically in response to allocation or scheduling of transmissions through the Tx chain 135, PA 161, and antenna 190. . However, it is not limited to this.

In one embodiment, the processor 120 configures the RFIC 130 associated with transmission of the first signal 191 based on the coupling signal 192 and the second signal 193 of the first signal 191. Among at least a portion of and at least a portion of the RFFE 160, a malfunctioning component of the electronic device 101 may be identified. The identification can be illustrated through FIG. 8.

FIG. 8 is a flow diagram illustrating an example method of identifying the state of a radio frequency front end (RFIC) and RFFE based on obtaining a coupling signal of a first signal and a second signal.

Referring to FIG. 8 , in operation 801, the processor 120 may obtain a coupling signal 192 and a second signal 193 of the first signal 191. For example, the processor 120 generates a first signal ( 191) can be transmitted and the coupling signal 192 of the first signal 191 can be obtained.

In operation 803, the processor 120 may identify whether the state of the coupling signal 192 of the first signal 191 is the first reference state. For example, the processor 120 executes operation 805 based on the coupling signal 192 of the first signal 191 in the first reference state and connects the first signal in a state different from the first reference state. Operation 807 may be executed based on the coupling signal 192 of 191.

At operation 805, processor 120 determines a device associated with the transmission of first signal 191 based on identifying the state of coupling signal 192 of first signal 191 as the first reference state. , it can be identified that at least a portion of the RFIC 130 and the RFFE 160 are in a normal operating state. For example, if the state of the coupling signal 192 of the first signal 191 is the first reference state, the path of the electronic device 101 for the transmission of the first signal 191 is normally operated. Because it indicates being in a state, the processor 120, based on the coupling signal 192 of the first signal 191 in the first reference state, Tx chain 135, Rx chain 145, and It can be identified that the state of the PA 161 is the normal operating state.

At operation 807, the processor 120 determines the state of the second signal 193 based on identifying that the state of the coupling signal 192 of the first signal 191 is different from the first reference state. It is possible to identify whether it is in the second reference state. For example, the processor 120 executes operation 809 based on a second signal 193 in the second reference state and operates based on a second signal 193 in a state different from the second reference state. You can run 811.

Figure 8 shows an example in which operation 807 is executed based on operation 803, but this is for convenience of explanation. For example, at least a portion of operation 803 and at least a portion of operation 807 of FIG. 8 may be executed in parallel. However, it is not limited to this.

At operation 809, the processor 120 determines the at least a portion of the RFFE 160 associated with the transmission of the first signal 191 based on identifying the state of the second signal 193 as the second reference state. It can be identified that the state is different from the normal operating state. For example, the fact that the state of the second signal 193 is the second reference state indicates that the state of at least a portion of the RFIC 130 related to the transmission of the first signal 191 is the normal operating state. , the processor 120 determines that the state of the RFFE 160 associated with the transmission of the first signal 191 is in the normal operation, based on identifying the state of the second signal 193 as the second reference state. Status and differences can be identified. For example, the processor 120 determines the PA based on the coupling signal 192 of the first signal 191 in a state different from the first reference state and the second signal 193 in the second reference state. It can be identified that the state of 161 is different from the normal operating state. For example, processor 120 may reset at least the portion of RFFE 160 associated with the transmission of first signal 191 based on the identification. For example, processor 120 may reset PA 161 based on the identification. However, it is not limited to this.

At operation 811, processor 120 determines the state of RFIC 130 associated with the transmission of first signal 191 based on identifying that the state of second signal 193 is different from the second reference state. It may be identified that at least some of the states are different from the normal operating state. For example, the state of the second signal 193 being different from the second reference state means that the state of the at least a portion of the RFIC 130 associated with the transmission of the first signal 191 is the normal operating state. and because it indicates that the state of the at least a portion of the RFIC 160 associated with the transmission of the first signal 191 may be different from the normal operating state, the processor 120 determines the state of the RFFE 160. Before identifying whether at least some of the states are the normal operating state, it may be identified that the at least some of the states of the RFIC 130 are different from the normal operating state. For example, the processor 120 is based on the coupling signal 192 of the first signal 191 in a state different from the first reference state and the second signal 193 in a state different from the second reference state. Thus, at least part of the RFIC 130 related to the transmission of the first signal 191 can be reset. For example, processor 120 may reset Tx chain 135 based on the identification. However, it is not limited to this.

Although not shown in FIG. 8, the processor 120, after resetting at least a portion of the RFIC 130, switches the first switch 150 in state 151 and the second switch 155 in state 156. Through this, a signal following the first signal 191 can be transmitted and a coupling signal of the signal can be obtained. Processor 120, in response to obtaining the coupling signal of the signal, may identify whether a state of the coupling signal of the signal is the first reference state. For example, the processor 120 may reset at least a portion of the RFFE 160 based on the coupling signal of the signal in a state different from the first reference state. However, it is not limited to this.

As described above, the electronic device 101 transmits the first signal 191 through obtaining the coupling signal 192 of the first signal 191 and obtaining the second signal 193. Among the components of the electronic device 101 used for this purpose, a malfunctioning component can be identified. For example, through such identification, the electronic device 101 can enhance the quality of communication through the electronic device 101.

The above examples describe that the electronic device 101 includes a first switch 150 and a second switch 155 in the RFIC 130 to obtain the second signal 193, but this is not explained. It is for your convenience. For example, first switch 150 and second switch 155 may be located outside of RFIC 130. For example, first switch 150 and second switch 155 may be located between RFIC 130 and RFFE 160. For example, the first switch 150 and/or the second switch 155 may be replaced with other components. For example, the electronic device 101 may include components for acquiring the second signal 193 with a design different from that illustrated in FIG. 1 . The other designs will be illustrated through FIGS. 9 to 10.

9-10 are simplified block diagrams of example electronic devices.

Referring to FIG. 9 , the electronic device 101 may include a coupler 900 that replaces the first switch 150 . For example, coupler 900 may be positioned between Tx chain 135 and PA 161.

For example, processor 120 may transmit first signal 191 to Tx chain 135, PA 161, and antenna based on setting the state of second switch 155 to state 156. It can be transmitted through 190, and the coupling signal 192 of the first signal 191 can be obtained through the Rx chain 145. For example, the processor 120 may execute the operations illustrated above with respect to the coupling signal 192 of the first signal 191.

For example, in response to setting the state of the second switch 155 to state 157, the processor 120 may generate a second signal that is a coupling signal of the first signal 191 obtained through the coupler 900. 2 signal 193 can be obtained through the Rx chain 145. For example, because the second signal 193 is a signal obtained through the coupler 900, unlike the coupling signal 192 of the first signal 191, it may indicate the state of the Tx chain 135. there is. For example, the processor 120 may execute the operations illustrated above with respect to the second signal 193.

As described above, the electronic device 101 can obtain the second signal 193 by including the coupler 900 instead of the first switch 150.

Referring to FIG. 10 , the electronic device 101 may include a first switch 1000 and a second switch 1050 that replace the first switch 150 and the second switch 155 . For example, the first switch 1000 and the second switch 1050 may be included in the RFFE 160, unlike the first switch 150 and the second switch 155. For example, the first switch 1000 may be included within the RFIC 130 or outside the RFIC 130 and the RFFE 160, depending on embodiments.

For example, the first switch 1000 has a first terminal 1011 connected to the Tx chain 135, a second terminal 1012 connected to the PA 161, and a third terminal of the second switch 1050. It may include a third terminal 1013 connected to (1063). For example, the second switch 1050 includes a first terminal 1061 connected to the coupler 170, a second terminal 1602 connected to the PA 161, and a third terminal of the first switch 1000 ( It may include a third terminal 1603 connected to 1013).

For example, the processor 120 electrically connects the Tx chain 135 to the PA 161 through the first switch 1000 and connects the PA 161 and the coupler 170 through the second switch 1050. Based on electrically connecting the antenna 190 (or the antenna 190), the first signal 191 obtained through the Tx chain 135 is transmitted through the antenna 190 at a power set using the PA 161. It can transmit and obtain the coupling signal 192 of the first signal 191 through the Rx chain 145. For example, the electrical connection between the Tx chain 135 and the PA 161 through the first switch 1000 is connected to the second terminal 1012 of the first switch 1000 and the first switch 1000. It can be formed by electrically connecting the second terminal 1012 of the first switch 1000 among the third terminals 1013 to the first terminal 1011 of the first switch 1000. For example, the electrical connection between Tx chain 135 and PA 161 may be provided through first switch 1000 in state 1001. For example, the connection between the PA 161 and the coupler 170 through the second switch 1050 may include the second terminal 1062 of the second switch 1050 and the third terminal of the second switch 1050. It can be formed by electrically connecting the second terminal 1062 of the second switch 1050 among the terminals 1063 with the first terminal 1061 of the second switch 1050. For example, the electrical connection between PA 161 and coupler 170 may be provided through a second switch 1050 in state 1051.

For example, the processor 120 has a Tx chain 135 electrically disconnected from the PA 161 through the first switch 1000 and the second switch 1050, and a coupler 170 electrically disconnected from the PA 161. ), the second signal 1093 obtained through the Tx chain 135 is transmitted through the antenna 190, and the coupling signal 1094 of the second signal 1093 is transmitted to the Rx It can be obtained through chain (145). For example, the electrical connection between the Tx chain 135 and the coupler 170 through the first switch 1000 and the second switch 1050 is connected to the second terminal 1012 of the first switch 1000. and electrically connecting the third terminal 1013 of the first switch 1000 to the first terminal 1011 of the first switch 1000, and electrically connecting the second terminal 1013 of the first switch 1000. Among the second terminal 1062 of the switch 1050 and the third terminal 1063 of the second switch 1050, the third terminal 1063 of the second switch 1050 is connected to the first terminal of the second switch 1050. It can be formed by electrically connecting with (1061). For example, the electrical connection between Tx chain 135 and coupler 170 may be provided through a first switch 1000 in state 1002 and a second switch 1050 in state 1052. .

For example, the processor 120 determines the state of the RFFE 160 and the RFIC ( 130) can be identified.

For example, since the coupling signal 192 is part of the first signal 191 transmitted through the Tx chain 135 and the PA 161, the coupling signal 192 is the first signal 191 It can indicate the status of the transmission path and the reception path of the coupling signal 192. For example, the coupling signal 192 may indicate the state of the Tx chain 135 and the state of the PA 161. For example, coupling signal 192 may indicate the state of Rx chain 145.

For example, since the coupling signal 1094 is generated through the Tx chain 135 and acquired through the Rx chain 145, the coupling signal 1094 is connected to one of the RFIC 130 and the RFFE 160. The status of the RFIC 130 may be indicated. For example, since the coupling signal 1094 does not pass through the PA 161, the coupling signal 1094 is the state of the Tx chain 135 among the states of the Tx chain 135 and the state of the PA 161. It can indicate status. For example, because the coupling signal 1094 does not pass through the PA 161, the coupling signal 1094 may indicate the state of the Rx chain 145.
