The disclosure relates to an electronic device and method of preventing deterioration by an operation of an antenna module.
When an antenna module of an electronic device, such as a smartphone, operates at maximum effective isotropic radiated power (EIRP) in a frequency range 2 (FR2) band, a part of beams generated by the antenna module may cause deterioration in an electronic module, such as a global positioning system (GPS), Wi-Fi, an ultra-wideband (UWB), long-term evolution (LTE), or a camera.
In addition, when an antenna module operates at maximum EIRP in an FR2 band in an electronic device including a slideable or foldable display, a part of beams generated by the antenna module may cause deterioration in an electronic module, such as a GPS, Wi-Fi, a UWB, LTE, or a camera according to a folding angle of the foldable display or an aspect ratio of the slideable display. Therefore, even when a terminal operates a band supporting FR2 (e.g., n256 and n257), a method of preventing performance deterioration of an electronic module may be needed.

The signal or the power may be transmitted or received between the communication module 190 and an external electronic device via the at least one selected antenna. Another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as a part of the antenna module 197.
According to various example embodiments, the antenna module 197 may form a mmW antenna module. According to an example embodiment, the mmW antenna module may include a PCB, an RFIC disposed on a first surface (e.g., the bottom surface) of the PCB, or adjacent to the first surface thereof and capable of supporting a designated high-frequency band (e.g., a mmW band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the PCB, or adjacent to the second surface thereof and capable of transmitting or receiving signals of the designated high-frequency band.
At least some of the above-described components may be coupled mutually and exchange signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).
According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and an external electronic device (e.g., the electronic device 104) via the server 108 coupled with the second network 199. Each of external electronic devices (e.g., the electronic devices 102 and 104) may be a device of the same type as or a different type from the electronic device 101. All or some of the operations to be executed by the electronic device 101 may be executed by one or more external electronic devices (e.g., the electronic devices 102 and 104 and the server 108). For example, if the electronic device 101 needs to perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices that have received the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request and may transfer an outcome of the performance to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, cloud computing, distributed computing, MEC, or client-server computing technology may be used, for example. The electronic device 101 may provide ultra-low-latency services using, for example, distributed computing or mobile edge computing.

According to an example embodiment, an external electronic device (e.g., the electronic device 104 or the server 108) may be included in the second network 199. The electronic device 101 may be applied to intelligent services (e.g., a smart home, a smart city, a smart car, or healthcare) based on 5G communication technology or IoT-related technology.
According to an embodiment, the processor 120 of the electronic device 101 may perform a method of preventing deterioration by an operation of the antenna module 197. According to an example embodiment, the electronic device 101 including a foldable or unfoldable display, for example, a rollable, slideable, or foldable display, for providing content, may deactivate a certain beam among beams of the antenna module 197 to reduce performance deterioration of an electronic module based on a state change of the display.
The electronic module (i.e., electronic circuitry) may refer to a module including modules needed by electronic components, such as the camera module 180, the communication module 190, and the sensor module 176 in the electronic device 101. The electronic module may include, for example, an ultra-wideband (UWB) module, a global positioning system (GPS) sensor, a Wi-Fi module, a long-term evolution (LTE) module, or the camera module 180. According to an example embodiment, the antenna module 197 of the electronic device 101 may include a mmW module (i.e., mmW circuitry).
According to another embodiment, the antenna module 197 may operate at maximum effective isotropic radiated power (EIRP) for communication (e.g., 5G communication) in a frequency range 2 (FR2) band or a microwave band. Accordingly, performance deterioration may be caused in the UWB module, the GPS sensor, the Wi-Fi module, the LTE module, or the camera module 180 among electronic modules.
In operation 201, the processor 120 may detect a state change of the display by using the sensor module 176. The state change may refer to a change of a form of a display, such as a change of a folding angle of a foldable display, a change of an aspect ratio in a slideable display, and the like.
The sensor module 176 may include a hall sensor for detecting an intensity of a magnetic field. When a form of the display changes, for example, a change of a folding angle of a foldable display, a change of an aspect ratio in a slideable display, and the like, the magnetic field may also change. The processor 120 may detect a state change of the display, based on a change of the magnetic field of the hall sensor.
The change of the magnetic field may be constant for each state change of the display, and the processor 120 may thus detect a state change of the display according to the change of the magnetic field and determine a current state of the display. In an example embodiment, when a foldable display is folded 180 degrees as illustrated in
In operation 202, the processor 120 may identify one or more operating electronic modules among electronic modules in the electronic device 101. The sequence of operations 201 and 202 may vary according to example embodiments. The processor 120 may identify an operating electronic module, for example, an operating UWB module, an operating GPS sensor, an operating Wi-Fi module, an operating LTE module, or an operating camera module (e.g., the camera module 180), in the electronic device 101. Identifying the operating electronic module may be implemented by a method readily implemented on, for example, Android, IO, and Tizen, by one of ordinary skill in the art.
In operation 203, the processor 120 may determine an electronic module in which deterioration is caused by an operation of the antenna module 197 among the operating electronic modules, based on a state change of the display.
According to yet another embodiment, when performance deterioration is caused by an electronic module, such as a UWB module, a GPS sensor, a Wi-Fi module, an LTE module, or the camera module 180, the received signal strength indication (RSSI) sensitivity measured by the electronic device 101 may be reduced. The processor 120 may calculate a noise level of the electronic module, such as a UWB module, a GPS module, a Wi-Fi module, an LTE module, or a camera module, in response to the performance degradation, based on the RSSI sensitivity.
According to an embodiment, the processor 120 may determine an electronic module in which deterioration is caused by an operation of the antenna module 197 among operating electronic modules, based on RSSI sensitivity. Information on electronic modules, in which performance deterioration is caused, may be preset based on RSSI sensitivity.
According to another embodiment, information on a type of an electronic module in which performance deterioration may be caused may be collected in advance for each state of a display, for example, a foldable display folded 90 degrees, a foldable display folded 180 degrees, a foldable display folded 0 degrees, a slideable display of which the height-to-width ratio is 16:9, or a slideable display of which the height-to-width ratio is 4:3.
In operation 204, the processor 120 may deactivate a certain beam among beams generated by the antenna module 197 to reduce deterioration of the determined electronic module. To compensate for the deactivated beam, the processor 120 may change a direction and a phase of each of the beams generated by the antenna module 197. The processor 120 may perform tilting on the beams or adjust a delay of the beams to compensate for the deactivated beam.
The processor 120 may calculate a noise level of the determined electronic module, and when the noise level is greater than or equal to a preset threshold, deactivate a certain beam among the beams generated by the antenna module 197 to reduce deterioration of the determined electronic module.
A threshold may not be limited to a certain value but may be preset by an experimentation or determined variously according to example embodiments. The processor 120, when the noise level is less than the threshold, without deactivating a certain beam of the antenna module 197, may maintain transmission at maximum EIRP by the antenna module 197.
Information on a beam causing performance deterioration may be collected in advance for each type of electronic module, for example, a UWB module, a GPS sensor, a Wi-Fi module, an LTE module, or the camera module 180, and for each state of a display, for example, a foldable display folded 90 degrees, a foldable display folded 180 degrees, a foldable display folded 0 degrees, a slideable display of which the height-to-width ratio is 16:9, or a slideable display of which the height-to-width ratio is 4:3.
The processor 120 may deactivate a certain beam among the beams of the antenna module 197 to minimize performance deterioration. A modified beam book may refer to a beam book for a mmW module in the antenna module 197.
The processor 120 may determine a beam causing deterioration in the determined electronic module among the beams generated by the antenna module 197. The processor 120 may determine a beam that may cause performance deterioration in an operating electronic module among the beams generated by the antenna module 197 in a current state of the display.
The processor 120 may deactivate the beam that may cause performance deterioration and generate the rest of the beams. The processor 120 may generate the rest of the beams, excluding the beam that may cause performance deterioration, and transmit the generated beams. The processor 120 may compensate for an output of the excluded beam by adjusting a delay of the rest of the beams, excluding the beam that may cause performance deterioration, or performing tilting on the rest of the beams.
Minimizing the effect of the beam that may cause performance deterioration may reduce the performance deterioration of an electronic module. In an example embodiment, when a foldable display is in a 90-degree folding state, performance deterioration may be caused in a GPS by a first beam.
The processor 120 may generate beams by using a beam book preset to reduce deterioration of the determined electronic module. According to an example embodiment, the processor 120 may modify a beam book of the antenna module 197 by using an artificial intelligence model trained to determine the beam book for minimizing performance deterioration of an electronic module, without excluding a beam causing performance deterioration of the determined electronic module among the beams generated by the antenna module 197.
The artificial intelligence model may be trained to determine the beam book, based on a state of the display and an electronic module. Input data of the artificial intelligence model may be the state of the display and the type of the electronic module. Output data may be a beam book for minimizing performance deterioration of the electronic module. The beam book may be information defining a direction and phase values of respective beams. The processor 120 may generate beams to be transmitted according to the beam book defining information on each beam.
According to an embodiment, reinforcement learning may be used for training of the artificial intelligence model. In an example embodiment, the processor 120 may train the artificial intelligence model for minimizing performance deterioration caused by a beam book determined by the artificial intelligence model. The artificial intelligence model may not be limited to a certain example, and various types of artificial intelligence models may be used.
According to another embodiment, the processor 120 may adjust an intensity of a part of beams to minimize performance deterioration, without excluding a beam causing performance deterioration in the determined electronic module among the beams generated by the antenna module 197, or by using a phase shifter (e.g., a phase shifter 403 of
According to yet another embodiment, when the antenna module 197 outputs transmission power of 24 decibel-milliwatts (dBm) with 10 beams, the processor 120 may determine an electronic module (e.g., a Wi-Fi module, an LTE module, a GPS module, a camera module, etc.) in which performance deterioration may be caused by 10 beams among currently operating electronic modules and modify a beam book for setting EIRP of a beam causing performance deterioration in the determined electronic module to 22 dBm, without excluding the beam causing the performance deterioration of the determined electronic module. The processor 120 may reduce EIRP by controlling a gain of a power amplifier of an RFIC.
When the display returns to an original state thereof, the processor 120 may detect a state change of the display and modify the beam book to a previously used beam book. In a case of a foldable display, the modification of the beam book may be performed when a folding angle of the foldable display is 90 degrees and when the folding angle is 180 degrees.
In a case of a foldable display, the modification of the beam book may be performed based on the type of an operating electronic module when a folding angle of the foldable display is 90 degrees and when the folding angle is 180 degrees. A state of the foldable display may not be limited to a certain example and may be determined variously according to example embodiments.
The modification of the beam book may be performed based on the type of an operating electronic module, when the height-to-width ratio of the slideable display is 20:9, when the height-to-width ratio of the slideable display is 16:9, and when the height-to-width ratio of the slideable display is 4:3. A state of the slideable display may not be limited to a certain example and may be determined variously according to example embodiments.
When the display is a bar type, performance deterioration may be caused in a portion of electronic modules (e.g., a UWB module, a GPS sensor, a Wi-Fi module, an LTE module, or the camera module 180), when the antenna module 197 operates at maximum EIRP, even without a state change of a display. A certain beam among beams generated by the antenna module 197 may be deactivated to reduce performance deterioration of an electronic module.
In operation 301, the processor 120 may identify one or more operating electronic modules among electronic modules in the electronic device 101. The processor 120 may identify an operating electronic module, for example, an operating UWB module, an operating GPS sensor, an operating Wi-Fi module, an operating LTE module, or an operating camera module (e.g., the camera module 180), in the electronic device 101.
In operation 302, the processor 120 may determine an electronic module in which deterioration is caused by an operation of the antenna module 197 among the operating electronic modules. For example, the processor 120 may determine the electronic module in which deterioration is caused by an operation of the antenna module 197 among operating electronic modules, based on RSSI sensitivity.
Information on electronic modules, in which performance deterioration is caused, may be preset based on RSSI sensitivity. In an example embodiment, information on a type of an electronic module in which performance deterioration may be caused may be collected in advance when the antenna module 197 operates in a mmW band at maximum EIRP.
In operation 303, the processor 120 may deactivate a certain beam among the beams generated by the antenna module 197 to reduce deterioration of the determined electronic module.
According to an embodiment, the processor 120 may calculate a noise level of the determined electronic module, and when the noise level is greater than or equal to a preset threshold, the certain beam among the beams generated by the antenna module 197 may be deactivated to reduce deterioration of the determined electronic module. A threshold may not be limited to a certain value but may be preset by experimentation or determined variously according to example embodiments. The processor 120, when the noise level is less than the threshold, without modifying a beam book of the antenna module 197, may maintain transmission at maximum EIRP by the antenna module 197.
According to another embodiment, when the antenna module 197 operates at the maximum EIRP in the mmW band, a beam that may cause performance deterioration may be collected in advance for each type of electronic module (e.g., a UWB module, a GPS sensor, a Wi-Fi module, an LTE module, or the camera module 180).
According to yet another embodiment, the processor 120 may determine a beam causing deterioration in the determined electronic module among the beams generated by the antenna module 197.

According to an embodiment, the processor 120 may deactivate the beam that may cause performance deterioration and generate the rest of the beams. The processor 120 may deactivate a beam identification (ID) to prevent the beam that may cause performance degradation from being generated.
The processor 120 may compensate for an output of the excluded beam by adjusting a delay of the rest of the beams, excluding the beam that may cause performance deterioration, or performing tilting on the rest of the beams. Minimizing the effect of the beam that may cause performance deterioration may reduce the performance deterioration of an electronic module.
According to another embodiment, performance deterioration may be caused in Wi-Fi by a second beam. The processor 120 may modify the beam book to compensate for the output of a first beam by using the rest of the beams, excluding the second beam.

For example, the artificial intelligence model may be trained to determine a beam book, based on a state of the display and an electronic module. Input data of the artificial intelligence model may be the state of the display and the type of the electronic module. Output data may be the beam book for minimizing performance deterioration of the electronic module.
According to an embodiment, reinforcement learning may be used for training of the artificial intelligence model. The processor 120 may train the artificial intelligence model for minimizing performance deterioration caused by the beam book determined by the artificial intelligence model. The artificial intelligence model may not be limited to a certain example, and various types of artificial intelligence models may be used.
According to another embodiment, the processor 120 may adjust an intensity of a part of beams for minimizing performance deterioration, without excluding a beam causing performance deterioration in the determined electronic module among the beams generated by the antenna module 197, or by using a phase shifter (e.g., the phase shifter 403 of
For example, when the antenna module 197 outputs transmission power of 24 decibels dBm with 10 beams, the processor 120 may determine an electronic module (e.g., a Wi-Fi module, an LTE module, a GPS module, a camera module, etc.) in which performance deterioration may be caused by 10 beams among currently operating electronic modules and modify a beam book for setting EIRP of a beam causing performance deterioration in the determined electronic module to 22 dBm, without excluding the beam causing the performance deterioration of the determined electronic module. The processor 120 may reduce EIRP by controlling a gain of a power amplifier of an RFIC.
