[0059] In FIG. 3, the electronic device (301) is illustrated as including an antenna (310), a communication circuit (320), a camera (330), a memory (340), and / or a processor (350), but is not limited thereto. For example, the electronic device (301) may further include at least one configuration that provides a function corresponding to the configuration illustrated in FIG. 1. The electronic device (301) may be implemented as a device including a communication circuit (e.g., a Wi-Fi chipset) and a camera, such as a smartphone, a wearable device (e.g., a smart watch, a smart band, and / or a smart ring), a PC (personal computer), or a tablet.

[0060] FIG. 4 is a flowchart illustrating a method for setting the transmission power of an RF signal based on the camera interface state of an electronic device according to one embodiment of the present disclosure. The embodiment of FIG. 4 is to be described with reference to FIG. 5a, FIG. 5b, and FIG. 6. FIG. 5a is an illustrative diagram illustrating the RF immunity of hardware included in an electronic device according to one embodiment of the present disclosure. FIG. 5b is an illustrative diagram illustrating a method for setting the transmission power of an RF signal of an electronic device according to a comparative example. FIG. 6 is an illustrative diagram illustrating a method for setting the transmission power of an RF signal of an electronic device according to one embodiment.

[0061] In one embodiment, the operations illustrated in FIG. 4 may be performed in various orders, not limited to the order illustrated. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. According to one embodiment, more operations may be performed than those illustrated in FIG. 4, or at least one fewer operation may be performed.

[0062] Referring to FIG. 4, in operation 401, in one embodiment, an electronic device (301) (e.g., processor (350)) may control a communication circuit (e.g., communication circuit (310)) to transmit an RF signal of a first transmission power. The first transmission power may be, for example, a maximum transmission power set for the electronic device (301). The first transmission power may be a transmission power identified by Wi-Fi configuration information. The RF signal may be a signal for Wi-Fi communication (e.g., a Wi-Fi signal in the 2.4 GHz, 5 GHz, and / or 6 GHz band), but is not limited thereto. In one embodiment, the RF signal may be a signal for cellular communication.

[0063] In one embodiment, the electronic device (301) may set the transmission power of the RF signal based on whether a camera (e.g., camera (330)) malfunctions due to RF interference ("RFI") caused by the RF signal. In one embodiment, a component included in the electronic device (301) (e.g., display module (160), camera (330) and / or processor (350)) may have RF immunity to RFI depending on the manufacturing process or material characteristics.

[0064] Referring to FIG. 5a, in one embodiment, a processor included in an electronic device (301) may have RF immunity within a MIPI variation range. RFI may be noise introduced into a component. RFI may occur due to operation associated with the radiation of RF signals from other components (e.g., antennas) included in the electronic device. The performance of components manufactured during mass production may have variation regarding RFI. Variation may be an indicator associated with non-uniformity occurring during the process. MIPI variation may be a physical upper or lower limit characteristic of the MIPI communication line. A sample having high RF immunity may be a component robust against RF noise. For example, if sample A having RF immunity close to the upper limit of the MIPI variation is included as a processor in the electronic device (301), the processor (e.g., processor (350)) can normally verify the signal provided by the camera even though a high transmission power RF signal is input into the processor. When sample B, which has RF immunity corresponding to the average of the MIPI dispersion, is included as a processor in the electronic device (301), the processor may not be able to properly verify the signal provided by the camera based on the RF signal having high transmission power being input into the processor. A sample having low RF immunity may be a component vulnerable to RF noise. For example, when sample C, which has RF immunity close to the lower limit of the MIPI dispersion, is included as a processor in the electronic device (301), the processor may not be able to properly verify the signal provided by the camera even though an RF signal having low transmission power is input into the processor.

[0065] In one embodiment, the camera included in the electronic device (301) may have RF immunity within the MIPI dispersion range. A sample having low RF immunity may be a component vulnerable to RF noise. For example, if sample D, which has RF immunity close to the lower limit of the MIPI dispersion, is included as a camera in the electronic device (301), a MIPI failure of the camera may occur even though an RF signal with low transmission power is input into the processor. If sample E, which has RF immunity corresponding to the average of the MIPI dispersion, is included as a camera in the electronic device (301), a MIPI failure of the camera may occur based on an RF signal with high transmission power being input into the processor. A sample having high RF immunity may be a component robust against RF noise. For example, if a sample F having RF resistance close to the upper limit of the MIPI dispersion is included in the electronic device (301), a camera MIPI failure may not occur even though an RF signal with high transmission power is fed into the processor.

[0066] Referring to FIG. 5b, in a comparative example, the backoff power of the RF signal (e.g., transmit power, backoff amount of transmit power, or backoff value of transmit power) can be set based on verifying the dispersion combination (or RF immunity) corresponding to the set (or DUT (device under test)). Table 1 describes an example of how the backoff power is set.

[0067] Sample Processor Camera RF Immunity [dBm] Back-off Power [dBm] Set #1CE1711 Set #2BE1511 Set #3BD1311 Set #4AF1711 Set #5CF1711

[0068] Referring to Table 1, each set (e.g., a MIPI block including an application processor and a camera) may have different RF immunity to RF radiated power. The first set (501) (Set #1) may have RF immunity corresponding to, for example, a combination of sample C and sample E. The first set (501) may have RF immunity to an RF signal having a transmit power of 17 dBm. The RF signal may be a signal proposed by IEEE 802.11n, but is not limited thereto. The second set (502) (Set #2) may have RF immunity corresponding to a combination of sample B and sample E. The second set (502) may have RF immunity to an RF signal having a transmit power of 15 dBm. The third set (503) (Set #3) may have RF immunity corresponding to a combination of sample B and sample D. The third set (503) may have RF immunity to an RF signal having a transmit power of 13 dBm. The fourth set (504) (Set #4) may have RF immunity corresponding to a combination of sample A and sample F. The fourth set (504) may be referred to as a sample of the upper limit dispersion combination. The fourth set (504) may have RF immunity to an RF signal having a transmit power of 17 dBm. The fifth set (505) (Set #5) may have RF immunity corresponding to a combination of sample C and sample F. The fifth set (505) may have RF immunity to an RF signal having a transmit power of 17 dBm. The eye diagram characteristics for MIPI communication of the samples corresponding to the lower limit dispersion combination (e.g., the second set (502) and the third set (503)) may be poor. In a comparative example, to prevent camera malfunction caused by the radiation power of the RF signal, a backoff table may be applied to some sets (501, 502, 503, 504, 505) during sample production in the development process (or test process).For example, a fixed backoff power (511) may be set based on a third set (503) having the lowest RF immunity. Fixed backoff power values ​​for sets (501, 502, 503, 504, 505) may be hardcoded in a processor (e.g., software NV parameter) (or memory). In a comparative example, if the backoff power is determined based on only some samples, the camera MIPI performance for all samples may not be corrected. In a comparative example, if the fixed backoff power is set based on the sample having the lowest RF immunity among the samples tested, backoff of excessive transmit power may be performed for samples having high RF immunity. Referring to FIG. 6, in one embodiment, the backoff power of the RF signal may be set differently based on identifying the dispersion combination corresponding to the set. Table 2 describes an example in which the backoff power corresponding to the RF immunity of the set is set differently.

[0069] Sample Processor Camera RF Immunity [dBm] Back-off Power [dBm] Set #1CE1717 Set #2BE1513 Set #3BD1311 Set #4AF1717 Set #5CF1717

[0070] In one embodiment, for sets having high RF immunity (e.g., first set (601), fourth set (604), and fifth set (605)), a high backoff power may be set. For sets having low RF immunity (e.g., the second set (602) and the third set (603)), a low backoff power may be set. In Table 2, content that overlaps with Table 1 may not be repeated. For the first set (601) having high RF immunity, for example, a backoff power (621) of 17 dBm may be set (611). For the second set (602) having low RF immunity, for example, a backoff power (622) of 13 dBm may be set (612). For the third set (603) having low RF immunity, for example, a backoff power (623) of 11 dBm may be set (613). For the fourth set (604) having high RF immunity, a backoff power (624) of 17 dBm may be set (614). The fifth set having high RF immunity For the set (605), a back-off power (625) of 17 dBm may be set (615). In one embodiment, the back-off power corresponding to the set may be set differently based on verifying the RF immunity corresponding to the set.

[0071] In operation 403, in one embodiment, the electronic device (301) can check the interface status of the camera. The electronic device (301) can check whether the camera is turned on based on a boot event of the electronic device (301). The boot event may be, for example, a power-on event of the electronic device. Based on confirming that the camera is turned on, the electronic device (301) can obtain a signal provided by the camera. The signal provided by the camera may be transmitted, for example, through a signal line connected between a processor and a camera. The electronic device (301) can check the camera interface status during the operation of a communication circuit (e.g., a Wi-Fi module).

[0072] In operation 405, in one embodiment, the electronic device (301) can determine whether the interface state of the camera is in a normal state. The electronic device (301) can determine the state of the camera's interface (e.g., MIPI interface) based on the state of the signal provided by the camera. For example, the electronic device (301) can determine whether the quality of the signal provided by the camera is good. Based on confirming that the signal quality is good, the electronic device (301) can determine that the camera's interface state corresponds to a normal state. Based on confirming that the signal quality is poor, the electronic device (301) can determine that the camera's interface state corresponds to an error state. In one embodiment, the electronic device (301) may determine the camera's interface state based on whether the signal information (e.g., flags or bits) provided by the camera corresponds to information indicating a normal state. For example, the electronic device (301) can determine that the camera's interface state corresponds to a normal state based on confirming that the signal information provided by the camera is a CAM MIPI pass. The electronic device (301) can confirm that the interface state of the camera corresponds to an error state based on confirming that the signal information provided by the camera is a CAM MIPI failure (or CAM MIPI error).

[0073] In one embodiment, based on confirming that the interface state of the camera is normal (Operation 405-Example), the electronic device (301) may, in Operation 407, set a first transmission power as the transmission power of the RF signal. The electronic device (301) may, based on confirming that the interface state of the camera corresponds to a normal state, confirm that no RFI occurs due to the transmission of the RF signal at the first transmission power. By setting the first transmission power as the transmission power of the RF signal (or Wi-Fi backoff power), the electronic device (301) may set a backoff power corresponding to the RF resistance of the components (e.g., processor and camera) of the electronic device (301).

[0074] In one embodiment, based on confirming that the interface state of the camera is not a normal state (operation 405-No), the electronic device (301) may, in operation 409, sequentially reduce the transmit power so that the interface state of the camera corresponds to a normal state. The electronic device (301) may, for example, determine the optimal transmit power that minimizes RFI by sequentially reducing the transmit power of the RF signal (e.g., increasing the backoff amount) until the interface state of the camera is confirmed to be a CAM MIPI pass. After transmitting the RF signal with reduced transmit power, if the interface state of the camera is confirmed to be a CAM MIPI pass, the electronic device (301) may set the reduced transmit power as the transmit power of the RF signal. In one embodiment, the electronic device (301) may set a minimum transmission power for RF communication (e.g., 11 dBm, with no numerical limit) if RFI is detected even after sequentially reducing the transmission power, based on the fact that the electronic device (301) may be a set having low immunity (e.g., Sample #3 of Table 2). The electronic device (301) may set the minimum transmission power set for the electronic device (301) as the transmission power of the RF signal if RFI is detected even after sequentially back-off of n dB from the maximum transmission power set for the electronic device (301), for example.

[0075] In one embodiment, the electronic device (301) can back off the transmission power of an RF signal only when the scatter combination of components of the electronic device (301) has low RF immunity, based on checking the MIPI interface status in an environment where both a communication circuit (e.g., a Wi-Fi communication circuit) and a camera are operating. The electronic device (301) can improve wireless communication (e.g., Wi-Fi communication) performance by setting a transmission power corresponding to the component characteristics of the electronic device (301).

[0111] In one embodiment, based on confirming that no camera MIPI failure occurs (operation 1013-No), the electronic device (301) may maintain a Wi-Fi back-off value in operation 1017. The electronic device (301) may maintain a set back-off power based on the fact that no RFI to the camera interface occurs due to the Wi-Fi communication currently being performed (or, radiated RF signal).

[0112] In one embodiment, based on confirming that a camera MIPI failure has occurred (Operation 1013-e.), the electronic device (301) may increase the Wi-Fi backoff value in Operation 1015. The electronic device (301) may increase the backoff value based on the occurrence of an RFI to the camera interface by the currently performing Wi-Fi communication (or, radiated RF signal). For example, the electronic device (301) may set the transmission power that does not cause camera malfunction as the backoff power of the RF signal for Wi-Fi communication based on sequentially increasing the backoff value in increments of 1 dB. In one embodiment, the electronic device (101) may sequentially increase the backoff value of the transmission power based on a specific backoff value, such as backoff the transmission power of the Wi-Fi signal from x dBm to (x - a) dBm, and backoff the transmission power of the Wi-Fi signal from (x - a) dBm to (x - 2a) dBm.

[0116] In one embodiment, the operations illustrated in FIG. 11 may be performed in various orders, not limited to the order illustrated. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. According to one embodiment, more operations may be performed than those illustrated in FIG. 11, or at least one fewer operation may be performed.

[0117] Referring to FIG. 11, in operation 1101, in one embodiment, an electronic device (301) (e.g., processor (350)) can set the transmission power of an RF signal based on the camera interface state. Operation 1101 is at least partially identical or similar to operation 407, and descriptions that overlap with operation 407 may not be repeated here.

[0118] In operation 1103, in one embodiment, the electronic device (301) can check information related to a currently running function. Referring to FIG. 12, in one embodiment, the electronic device (301) can check information related to a currently running function based on information related to camera settings, information related to hardware, information related to short-range wireless communication, and information related to cellular communication. The electronic device (301) (e.g., processor (350)) may include a plurality of blocks. The plurality of blocks may include a camera block (1210), a baseband block (1220), a connectivity block (1230), a main RF block (1240), an AI block (1250), and a CAM error check block (1260).

[0119] In one embodiment, the camera block (1210) can obtain information associated with a camera configuration corresponding to a plurality of cameras including an ultra-wide angle camera (1211), a wide angle camera (1213), a telephoto camera (1215), and a front camera (1217). The baseband block (1220) can obtain information associated with hardware that operates based on baseband signals, such as an application processor (1221), a display (1223), audio (1225), and a sensor (1227). The connectivity block (1230) can obtain information associated with short-range wireless communication. For example, the connectivity block (1230) can obtain information associated with antennas (1231, 1233) transmitting signals of a first band (e.g., 2.4 GHz), antennas (1235, 1237) transmitting signals of a second band (e.g., 5 GHz), and an antenna (1239) transmitting UWB (ultra wideband) signals. In one embodiment, the main RF block (1240) can obtain information associated with cellular communication. For example, the main RF block (1240) can obtain information associated with a first main antenna (1241), a second main antenna (1243), a first sub-antenna (1245), and a second sub-antenna (1247). The electronic device (301) can check information related to the currently running function based on information obtained by the camera block (1210), baseband block (1220), connectivity block (1230), main RF block (1240), AI block (1250), and CAM error check block (1260).

[0120] In one embodiment, blocks implemented (or stored) in the electronic device (101) (e.g., camera block (1210), baseband block (1220), connectivity block (1230), main RF block (1240), AI block (1250), and / or CAM error check block (1260)) may be implemented in the form of an application, program, computer code, instructions, routine, process, software, firmware, or a combination of at least two of these that are executable by the processor (350). For example, when blocks (or modules) are executed, the processor (350) may perform an operation corresponding to each. In this disclosure, the description “a specific block performs an operation” may be understood as “the processor (350) performs an operation corresponding to a specific block as the specific block is executed.” In one embodiment, at least some of the blocks may include a plurality of programs, but are not limited to those described. Meanwhile, at least some of the blocks may be implemented in a hardware form (e.g., processing circuit (not shown)). In one embodiment, the blocks may be implemented as a service or application when implemented on an Android operating system.

[0121] In operation 1105, in one embodiment, the electronic device (301) can obtain a predicted backoff value of transmission power based on information output from a backoff value prediction model by inputting information related to a currently running function into the backoff value prediction model. Referring again to FIG. 12, the electronic device (301) can input information related to a currently running function, identified based on information related to camera settings, information related to hardware, information related to short-range wireless communication, and information related to cellular communication, into an AI block (1250). The AI ​​block (1250) may include at least one of a machine learning model (1251), a DNN (1253) (deep neural network), a CNN (1255) (convolutional neural network), or an RNN (1257) (recurrent neural network). The AI ​​block (1250) may be implemented, for example, as a generative AI model. In one embodiment, the AI ​​block (1250) may be a backoff value prediction model trained to output a predicted value of the transmission power of an RF signal that minimizes RFI based on receiving information associated with a currently operating function. The backoff value prediction model may be trained using data acquired in advance.

[0122] In one embodiment, the input data of the backoff value prediction model may be a combination of camera information and antenna information. For example, the input data of the backoff value prediction model may include camera MIPI check information, camera type, band, frequency, channel, transmission power, modulation scheme, and information associated with RAT for wireless communication. The electronic device (301) can obtain a predicted backoff value of transmission power based on the information output from the backoff value prediction model by inputting information associated with the currently executing function into the backoff value prediction model.

[0123] In operation 1107, in one embodiment, the electronic device (301) can transmit an RF signal having reduced transmission power based on a predicted backoff value. The electronic device (301) can transmit an RF signal having transmission power corresponding to a backoff value identified based on information output by a backoff value prediction model.

[0124] In operation 1109, in one embodiment, the electronic device (301) can check whether the camera interface state is normal. The electronic device (301) can check the camera interface state by transmitting an RF signal having reduced transmission power based on a predicted backoff value. The electronic device (301) can check whether camera malfunction occurs due to transmission power corresponding to the backoff value predicted by the backoff value prediction model. Referring again to FIG. 12, the CAM error checking block (1260) can check whether the predicted backoff value corresponding to a parameter condition (e.g., information related to a currently running function) is ground truth based on the output information of the AI ​​block (1250).

[0125] In one embodiment, based on confirming that the camera interface state corresponds to a normal state (Operation 1109-Example), the electronic device (301) can confirm in Operation 1111 that the result value corresponding to the predicted backoff value is ground truth. The electronic device (301) can obtain the result value corresponding to the predicted backoff value based on the camera interface state. The electronic device (301) can confirm that the result value corresponding to the predicted backoff value is ground truth based on confirming that the camera interface state corresponds to a CAM normal operation state. The electronic device (301) can store ground truth including input data (e.g., parameter conditions) and the predicted backoff value based on confirming that no RFI issue occurs even when transmitting an RF signal having a transmission power corresponding to the backoff value output by the backoff value prediction model.

[0126] In one embodiment, based on confirming that the camera interface state does not correspond to a normal state (Operation 1109-No), the electronic device (301) can check the output value of the loss function in Operation 1113. The electronic device (301) can check the loss value corresponding to the output backoff value based on confirming that an RFI issue occurs when transmitting an RF signal having a transmission power corresponding to the backoff value output by the backoff value prediction model. The electronic device (301) can check the output value of the loss function, for example, by checking the difference between a previously stored label and the output backoff value, but is not limited thereto. Referring again to FIG. 12, the CAM error checking block (1260) can provide a result value for parameter relearning to the AI ​​block (1250) if the output value for the predicted backoff value corresponds to a CAM MIPI error. The AI ​​block (1250) can update multiple parameters included in the backoff value prediction model so that the output value of the loss function is minimized.

[0128] In one embodiment, the operations illustrated in FIG. 13 are not limited to the order illustrated and may be performed in various orders. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. According to one embodiment, more operations than those illustrated in FIG. 13 may be performed, or at least one fewer operation may be performed.

The backoff value prediction model may be a pretrained model by an external electronic device. The electronic device (301) may store a generative AI model that includes some of the large-scale (e.g., billions to hundreds of billions) parameters included in the pretrained model.

[0130] In one embodiment, the electronic device (301) can set the transmission power of an RF signal based on information output by a generative AI model and, after transmitting an RF signal having the set transmission power, check whether the camera interface state is in a normal state.

The electronic device (301) can set the transmission power of an RF signal corresponding to the obtained backoff value. The electronic device (301) can transmit an RF signal having the set transmission power. After transmitting the RF signal, the electronic device (301) can check whether the camera interface state is in a normal state.

For example, if the interface state is normal, the electronic device (301) can designate a result value for the predicted backoff value as "pass". If the interface state is error, the electronic device (301) can designate a result value for the predicted backoff value as "fail". The electronic device (301) can train (or fine-tune) a backoff value prediction model based on the result value for the backoff value.
