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

According to one embodiment, the electronic device 200 (e.g., the electronic device 101 of FIG. 1) includes a processor 210 (e.g., the processor 120 or communication module 190 of FIG. 1) and a memory 220. It may include (e.g., memory 130 in FIG. 1), transceiver 230, amplifier 240, filter 250, and antenna 260 (e.g., antenna module 197 in FIG. 1).

According to one embodiment, the processor 210 may control the operation (eg, communication) of the electronic device 200 by executing instructions stored in the memory 220. For example, the processor 210 may include an application processor (AP) (e.g., the main processor 121 of FIG. 1) and/or a communication processor (CP) (e.g., the auxiliary processor 123 of FIG. 1). ) or a communication module 190). Communications processor 210 may include a modem. For example, processor 210 may transmit a baseband signal to transceiver 230. The processor 210 may control transmission of the transmission signal to the network through the transmission path 270 (e.g., transceiver 230, amplifier 240, filter 250, and antenna 260). The processor 210 may use the transceiver 230 to obtain a feedback signal (or information about the feedback signal) obtained through the feedback path 280. The processor 210 may monitor the size and frequency of the emitted transmission signal based on the feedback signal. For example, based on the feedback signal, the processor 210 may monitor whether the transmission signal has a designated frequency band and/or the signal strength (i.e., power strength) in the designated frequency band. The processor determines whether the transmission signal (or feedback signal) is inband (within the offset range according to the specified bandwidth) based on the specified carrier frequency or outband (within the offset range according to the specified bandwidth). You can monitor whether it belongs to the outside). For example, based on the feedback signal, the processor 210 determines whether the transmission signal has frequency band components (e.g., spurious components) other than the specified frequency band, and determines the signal strength (amplitude) in the specified frequency band. ), and/or the signal strength (size) of a frequency band other than the designated frequency band can be detected. The processor 210 may continuously or periodically monitor the state of the feedback signal as it emits the transmission signal and detect errors in the transmission signal. For example, an error in a transmitted signal may include a case where the transmitted signal has an unwanted frequency (e.g., a frequency band other than a designated frequency band). The processor 210 monitors the power related to the transmission signal (or reflected signal) through the feedback path 280, and when an error occurs in the monitored power, the frequency, phase, and and/or the size may be corrected,

For example, the processor 210 may adjust the transmission signal output using the transceiver 230 based on the monitoring results. The processor 210 may adjust the frequency of the transmission signal output from the transceiver 230 when the transmission signal has components in an unwanted frequency band (i.e., a frequency band other than the designated frequency band). For example, the processor 210 may adjust the frequency of the transmission signal so that the frequency of the transmission signal falls within a designated frequency band through at least one PLL circuit 231 included in the transceiver 230.

For example, as a result of monitoring the feedback signal, the processor 210 detects a specified error indicating that the size of the frequency band component of the transmission signal other than the specified frequency band is greater than the threshold value, more than a specified number of times in succession, the transceiver 230 , the settings of at least one of the amplifier 240 and the processor 210 can be changed. For example, the processor 210 may classify a case where the size of a specified frequency band component of the transmission signal is below the lower limit and/or when the size of a frequency band component other than the specified frequency band of the transmission signal is greater than the upper limit as a designated error. It can be detected. For example, the processor 210 detects a designated error when the monitoring result of the feedback signal has an error value greater than a threshold value to the extent that it is determined that correction cannot be made by the operation of the general transceiver 230 (e.g., the PLL circuit 231). It can be detected as. For example, the processor 210 may determine a specified number of times two or more times. For example, the limit value (upper limit or lower limit) may mean a value set to determine that a communication error that has occurred is of an unrecoverable level. For example, the threshold may be an error value set as an error value (signal power (strength)) of a signal (transmission signal or feedback signal) relative to a reference value to indicate an unrecoverable error. For example, a specified error being detected multiple times in succession means that the error is not resolved even though the transmission signal output by the transceiver 230 (e.g., PLL circuit 231) is adjusted to reflect the monitoring results of the feedback path. It can mean.

For example, when the processor 210 detects a specified error in succession more than a specified first number of times as a result of monitoring, the processor 210 may reset the setting value of the PLL circuit 231 of the transceiver 230 to the specified initial value. For example, the processor 210 may reperform the phase locking operation of the PLL circuit 231 (perform relocking).

For example, the processor 210 may disable the phase lock function of the PLL circuit 231 in certain situations (e.g., to reduce current consumption) before detecting a specified error more than a specified first number of times in succession. You can. The processor 210 may set the phase lock function of the PLL circuit 231 to always be activated when a specified error is continuously detected a specified first number of times.

For example, after resetting the setting value of the PLL circuit 231, the processor 210, when continuously detecting the specified error more than a specified second number of times, uses resources related to communication (e.g., transmission of a signal and You can reset the settings of (related resources) to the specified initial value. For example, the resources include the PLL circuit 231, the amplifier 240, the low noise amplifier (LNA) included in the transceiver 230, the filter 250, the antenna 260, and the antenna. It may include at least one of a tuner (260) and a switch of a circuit related to communication. According to one embodiment, resources related to communication are not limited to those mentioned above and may include components used for communication (eg, front-end components).

For example, if the processor 210 detects a specified error more than a specified third time in succession after resetting the settings values of the resources, the processor 210 may reset the settings value of the processor 210 to the specified initial setting value. . As an example, the processor 210 may reboot software that controls the operation of the processor 210.

For example, if the processor 210 detects a specified error more than a specified fourth number of times in succession after resetting the setting value of the processor 210, the maximum transmission power value in the specified frequency band is limited to the specified value. (override) can be done. For example, the processor 210 limits the maximum transmission power value, thereby causing components (e.g., amplifier 240) of the processor 210 to be damaged by transmission signals (or reflected signals of transmission signals) in unwanted frequency bands. This can prevent damage.

For example, after limiting the maximum transmission power value, the processor 210 may deactivate communication for the specified frequency band when detecting a specified error more than a specified fifth number of times in succession. For example, when transmitting a UE capability message to the network, the processor 210 may control the message to be transmitted so that communication is deactivated for the corresponding frequency band. The processor 210 may transmit a UE capability message containing information indicating that the electronic device 200 does not support the specified frequency band to the network. For example, the first time, the second time, the third time, the third time. The 4th number of times and the 5th number of times may each be set differently, or at least some of them may be set to be the same.

According to one embodiment, in operation 310, an electronic device (e.g., the electronic device 101 of FIG. 1 or the electronic device 200 of FIG. 2) uses a transceiver (e.g., the transceiver 230 of FIG. 2) to Transmission signals in the frequency band can be output. A processor (e.g., communication processor (e.g., modem)) of an electronic device (e.g., processor 120 in FIG. 1, communication module 190 in FIG. 1, or processor 210 in FIG. 2) transmits data to the network. A bandwidth signal can be generated to do this. The transceiver can convert a baseband signal into a transmission signal in a designated frequency band and output it.

According to one embodiment, in operation 320, the electronic device uses an amplifier (e.g., amplifier 240 of FIG. 2) disposed on a transmission path (e.g., transmission path 270 of FIG. 2) electrically connected to the transceiver. This allows the transmission signal to be amplified.

According to one embodiment, in operation 330, the electronic device may filter the amplified transmission signal to a designated frequency band using a filter (eg, filter 250 of FIG. 2) disposed on the transmission path. For example, a filter may include a duplexer.

According to one embodiment, in operation 340, the electronic device may radiate the filtered transmission signal through an antenna (eg, the antenna module 197 of FIG. 1 or the antenna 260 of FIG. 2). Electronic devices can transmit or receive signals to the outside (e.g., a network, external device, or base station) through an antenna. Electronic devices can transmit data to a network through transmission signals.

According to one embodiment, in operation 350, the electronic device uses a transceiver to obtain a feedback signal related to the transmission signal through a feedback path (e.g., the feedback path 280 in FIG. 2) connected between the transmission path and the transceiver. You can. For example, the feedback signal may be associated with a transmitted signal, or the transmitted signal may be associated with a reflected signal reflected by an antenna.

According to one embodiment, in a 360 operation, the electronic device may monitor the size and frequency of the emitted transmission signal based on the feedback signal. For example, based on the feedback signal, the electronic device may monitor whether the transmission signal has a designated frequency band and/or the signal strength (i.e., power strength) in the designated frequency band. Based on the feedback signal, the electronic device determines whether the transmitted signal has frequency band components (e.g., spurious components) other than the specified frequency band, the signal strength (amplitude) in the specified frequency band, and/or the specified frequency band. The signal strength (size) of a frequency band other than the frequency band can be detected. As an electronic device emits a transmission signal, it can continuously or periodically monitor the state of the feedback signal and detect errors in the transmission signal. For example, an error in a transmitted signal may include a case where the transmitted signal has an unwanted frequency (e.g., a frequency band other than a designated frequency band).

According to one embodiment, in operation 370, the electronic device may adjust a transmission signal output using a transceiver based on the monitoring result. The electronic device can adjust the frequency of the transmission signal output from the transceiver when the transmission signal has components in an unwanted frequency band (i.e., a frequency band other than the designated frequency band). The transceiver may include a PLL circuit (eg, PLL circuit 231 in FIG. 2). The transceiver can adjust the frequency of the transmission signal through a PLL circuit so that the frequency of the transmission signal falls within a designated frequency band.

According to one embodiment, in operation 380, when the electronic device detects, as a result of monitoring, a specified error indicating that the size of a frequency band component other than the specified frequency band of the transmission signal is greater than a threshold value, the transceiver and amplifier You can change the settings of at least one of , and processor.

0	235	0	2	1907500	0	0
One	130	0	2	1907500	0	0
2	235	0	2	1907500	0	0
3	235	0	2	1907500	0	0

8	130	0	2	1907500	0	0
9	235	0	2	1907500	0	0

In Table 1, Txagc represents the level of transmitted transmission power, and represents the value written in dB units. For example, 235 in item 0 may represent 23.5dBm. Tech ID refers to the type of wireless communication technology. For example, a natural number ID depending on the type of wireless communication technology such as LTE (long-term evolution), NR (new radio), or WCDMA (wideband code division multiple access). A code value may be specified. Band is a code value indicating the bandwidth band currently being used by the electronic device, and Tx Freq indicates the center frequency (e.g. carrier frequency) of the currently specified transmission signal. For example, Tx Freq may represent the center frequency locked by the transceiver (e.g., PLL circuit). Carrier Idx may be a code value for identifying the carrier. Pwr Err Code may represent a code value according to a pre-designated type of communication error. For example, code 2 in items 4 to 6 may indicate an error in the transmission power of the transmission signal detected based on the feedback signal. For example, the electronic device can check the Pwr Err Code to detect when a specified error occurs more than a specified number of times in succession. For example, the names, code values, and classifications of the items in Table 1 are only examples and are not limited thereto, and information obtained by an electronic device monitoring a feedback signal is not limited to the form of a table. For example, the electronic device may further include information on the gain state of a low noise amplifier (LNA) inside the transceiver and/or the state information of the function (or solution, or algorithm) being used in the electronic device.

0	-110	LTE	0	One
One	-90	LTE	One	0

In Table 2, txagc represents the level of transmitted transmission power, represents a value written in dB units, and tech may represent the type of wireless communication technology. hdb is a value for detecting signals of unwanted frequencies. A lower value may indicate that the size of the signal in the specified frequency band is reduced. For example, fdb represents the power error level of the feedback signal and can represent the degree of power error (error) across the entire bandwidth. For example, fdb is a value for detecting the magnitude error level of a feedback signal. A larger value may indicate that the magnitude of a signal generated in an unwanted frequency band increases. For example, fdb may have a code value from 0 to 120, and a code value of 120 may indicate that a signal strength of 12 dB or more has been detected. For example, when the limit value (maximum value) of fdb is set to 120, the electronic device can detect the case where fdb has a code value of 120 as a designated error. For example, based on the feedback signal, the electronic device determines whether the amplitude of the signal in a specified frequency band of the transmitted signal or the amplitude of the signal (e.g., unwanted wave) in a frequency band other than the specified frequency band is greater than or equal to a specified threshold. A specified error can be detected. For example, the names, code values, and classifications of the items in Table 2 are only examples and are not limited thereto, and the information obtained by the electronic device monitoring the feedback signal is not limited to the form of a table.

For example, as a result of monitoring the feedback signal, the electronic device may detect that a specified error indicating that the size of a frequency band component other than the specified frequency band of the transmission signal is greater than a threshold value occurs continuously more than a specified number of times. For example, the electronic device may detect as a designated error when the size of a component of a specified frequency band of a transmission signal is below the lower limit and/or when the size of a component of a frequency band other than the specified frequency band of the transmission signal is above the upper limit. You can. For example, the electronic device may detect as a designated error a case where the monitoring result of a feedback signal has an error value greater than a threshold value to the extent that it is determined that correction cannot be made through the operation of a general transceiver (e.g., PLL circuit). For example, the electronic device may determine the specified number of times to be two or more times.

For example, when the electronic device detects a specified error more than a specified first number of times in succession as a result of monitoring, the electronic device may reset the setting value of the PLL circuit of the transceiver to a specified initial value. For example, the electronic device may reperform the phase locking operation of the PLL circuit.

For example, the electronic device may disable the phase lock function of the PLL circuit to reduce current consumption before detecting a specified error more than a specified first number of times in succession. The electronic device may be set to always activate the phase lock function of the PLL circuit when a specified error is detected in succession a specified number of times or more.

For example, after resetting the setting value of the PLL circuit, the electronic device may reset the setting value of resources related to signal transmission to a designated initial value when detecting the specified error more than a specified second number of times in succession. there is. For example, the resources include at least one of a PLL circuit, an amplifier, a low noise amplifier (LNA) included in a transceiver, a filter, an antenna, and a tuner of the antenna, and a switch included in a communication-related circuit. can do.

For example, if the electronic device detects a specified error more than a specified third number of times in succession after resetting the settings values of resources, the electronic device may reset the processor settings to the specified initial setting value. For example, the electronic device may reset the settings of the communication processor (eg, modem) to initial settings.

For example, if the electronic device detects a specified error more than a specified fourth number of times in succession after resetting the setting value of the processor, the electronic device may limit (override) the maximum transmission power value in the specified frequency band to a specified value. there is. For example, by limiting the maximum transmit power value, electronic devices can prevent components (e.g. amplifiers) of the electronic device from being damaged by transmitted signals (or reflected signals of transmitted signals) in unwanted frequency bands. there is.

For example, after limiting the maximum transmission power value, the electronic device may deactivate communication for the specified frequency band when detecting a specified error more than a specified fifth number of times in succession. For example, when transmitting a UE capability message to the network, the electronic device may transmit a message to disable communication for the corresponding frequency band. For example, the first number of times, the second number of times, the third number of times, the fourth number of times, and the fifth number of times may each be set differently, or at least some of them may be set to be the same.

For example, the electronic device may send error-related information (e.g. information related to limiting the maximum transmit power value or disabling communications for a given band) to an external server. (e.g., it can be provided to the manufacturer’s server).
