Description

Uplink transmission power control method and electronic device therefor

[0001] Embodiments disclosed in this document relate to an uplink transmission power control method and an electronic device therefor.

[0002] A user equipment (UE) may transmit a wireless signal for data transmission and reception with a base station. The transmission power of the wireless signal of the UE may be limited by a maximum transmission power limit (MTPL). The MTPL of the UE may be referred to, for example, as a maximum transmission power (e.g., PcMax) of the UE set for the UE. The UE may set the maximum transmission power based on a network MTPL (e.g., PeMax) set by a network and / or a UE-defined MTPL based on the capabilities of the UE. The UE may set the maximum transmission power based on a smaller value between the network MTPL and the UE-defined MTPL. The UE-defined MTPL may be determined based on a maximum power reduction (MPR), an additional MPR (AMPR), and a specific absorption rate (SAR).

[0003] A user device can control the transmission power of a wireless signal using a power amplifier (PA). The user device can control the transmission power by controlling the gain of the PA. Due to the nonlinear characteristics of the PA, harmonic signals may be generated in the transmission signal. The harmonic signals may cause intermodulation distortion (IMD). Furthermore, the harmonic signals may be amplified by a power amplifier located in another transmission path. Due to the harmonic components, the quality of the transmission signal (e.g., adjacent channel leakage ratio (ACLR) and / or error vector magnitude (EVM)) may deteriorate, or a relatively strong IMD component may be included in the transmission signal.

[0031] Hereinafter, various embodiments of the present invention will be described with reference to the attached drawings. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that the present invention encompasses various modifications, equivalents, and / or alternatives of the embodiments.

[0032] Figure 1 illustrates a network environment of an electronic device according to one embodiment.

[0033] Referring to FIG. 1, according to one embodiment, the electronic device (10) may include any portable electronic device. The electronic device (10) may include, for example, at least one of a mobile phone, a smart watch, smart glasses, a smart ring, and / or an Internet of Things (IoT) device.

[0034] In one example, the electronic device (10) may be referred to as a communication device configured to support wireless communication. For example, the electronic device (10) may include any electronic device that supports carrier aggregation and / or dual connectivity. For example, the electronic device (10) may include a user device having mobility or any wireless electronic device. For example, the dual connectivity may include multi-RAT dual connectivity (MR-DC) that supports dual connectivity based on different radio access technologies (RATs).

[0035] In one example, the first base station (20) may be associated with at least one cell. For example, the first base station (20) may be associated with the 1-1 cell (21) and / or the 1-2 cell (22). For example, the 1-1 cell (21) and the 1-2 cell (22) may be cells of the same RAT. In another example, the 1-1 cell (21) and the 1-2 cell (22) may be cells having different RATs.

[0036] In one example, the second base station (30) may be associated with at least one cell. For example, the second base station (30) may be associated with the 2-1 cell (31) and / or the 2-2 cell (32). For example, the 2-1 cell (31) and the 2-2 cell (32) may be cells of the same RAT. In another example, the 2-1 cell (31) and the 2-2 cell (32) may be cells having different RATs.

[0037] In one example, the electronic device (10) can perform MR-DC-based communication through the first base station (20). For example, the 1-1 cell (21) can support 4G RAT-based communication, and the 1-2 cell (22) can support 5G RAT-based communication. The 1-1 base station (20) may be physically located in one location, but may be a base station connected to multiple core networks. For example, the electronic device (10) can perform MR-DC-based communication by being connected to the 1-1 cell (21) and the 1-2 cell (22) simultaneously (or substantially simultaneously). Similarly, the electronic device (10) can perform MR-DC-based communication through the 2-1 cell (31) and the 2-2 cell (32) of the second base station (30).

[0038] In one example, the electronic device (10) can perform MR-DC-based communication via the first base station (20) and the second base station (30). For example, the 1-1 cell (21) can support 4G RAT-based communication, and the 2-1 cell (31) can support 5G RAT-based communication. For example, the electronic device (10) can perform MR-DC-based communication by being connected to the 1-1 cell (21) and the 2-1 cell (31) simultaneously (or substantially simultaneously).

[0039] In one embodiment, the electronic device (10) may perform carrier aggregation via a plurality of component carriers associated with the first base station (20) or the second base station (30). For example, the electronic device (10) may perform carrier aggregation via a first carrier associated with the 1-1 cell (21) and a second carrier associated with the 1-2 cell (22).

[0040] The communication system (100) associated with the electronic device (10) described above with reference to FIG. 1 is exemplary, and embodiments of the present disclosure are not limited thereto. The network environment illustrated in FIG. 1 is an example, and at least one base station and / or at least one cell may be omitted from the communication system (100).

[0041] FIG. 2 illustrates a block diagram of an electronic device according to one embodiment.

[0042] Referring to FIG. 2, according to one embodiment, an electronic device (10) may include a plurality of antennas (210), a sensor (230), a communication circuit (240), a transceiver (250), a processor (260), and a memory (270). The electronic device (10) may correspond to the electronic device (1900) of FIG. 19. The structure of the electronic device (10) illustrated in FIG. 2 is exemplary, and the embodiments of the present document are not limited thereto. For example, the electronic device (10) may further include a configuration not illustrated in FIG. 2 (e.g., the configuration of the electronic device (1900) of FIG. 19).

[0043] The plurality of antennas (210) may include a first antenna (211) and / or a second antenna (213). For example, the first antenna (211) and / or the second antenna (213) may include a radiator that can be used as an antenna. The number of antennas included in the plurality of antennas (210) illustrated in FIG. 2 is exemplary, and embodiments of the present disclosure are not limited thereto. For example, the plurality of antennas (210) may additionally include a third antenna and a fourth antenna.

[0044] For example, the electronic device (10) may transmit an uplink signal or uplink signals using a plurality of antennas (210). In one example, the electronic device (10) may transmit a single uplink signal in a single input single output (SISO) manner using one of the plurality of antennas (210).

[0045] For example, the electronic device (10) may transmit uplink signals in a multiple input multiple output (MIMO) manner using at least two of the plurality of antennas (210). "MIMO" may be referred to as a term that includes a wireless signal transmission and reception method to which spatial multiplexing and / or spatial diversity are applied. For example, the MIMO scheme may include a scheme for transmitting single uplink signals using multiple transmit / receive antennas (e.g., spatial multiplexed single layer (SMSL) and / or multiple input multiple output transmit diversity (MIMO TxD)) and / or a scheme for transmitting multiple independent uplink signals using multiple antennas (e.g., spatial multiplexed dual layer (SMDL). Spatial multiplexing may include, for example, a technology for transmitting multiple independent uplink signals in parallel using multiple transmit / receive antennas. For example, in the case of a MIMO system (e.g., 4×4 MIMO) using four transmit antennas and four receive antennas, spatial multiplexing may be applied to transmit four independent uplink signals simultaneously. Spatial diversification may include, for example, a technology for transmitting single uplink signals through multiple paths using multiple transmit / receive antennas arranged at different locations of the electronic device (10). For example, in the case of a MIMO system using four transmit antennas and four receive antennas, spatial diversification may be applied. It can be applied to transmit single uplink signals along four different paths.

[0046] For example, the electronic device (10) may transmit uplink signals in a multiple input single output (MISO) manner using at least two of the plurality of antennas (210). "MISO" may be referred to as a term including a wireless signal transmission and reception method to which spatial multiplexing and / or spatial diversity are applied. For example, the MISO method may include a method of transmitting single uplink signals using a plurality of transmit / receive antennas and / or a method of transmitting a plurality of independent uplink signals using a plurality of antennas.

[0047] For example, the first antenna (211) may include a portion of a housing of the electronic device (10) (e.g., a portion of a side member), a metallic pattern, a metallic radiator, and / or a conductive member. For example, at least a portion of the housing may be used as the first antenna (211). For example, the housing may include a metallic member, and the metallic member may be electrically separated by a dielectric segment (e.g., the first segment (501) and / or the second segment (502) of FIG. 5). A portion of the electrically separated metallic member may be used as the first antenna (211). For example, at least one of the portions of the housing separated by the segment (e.g., 511, 512, 513, 514, 515, 521, 522, and / or 523 of FIG. 5) may be used as the first antenna (211).

[0048] For example, the electronic device (10) may include a substrate positioned within the housing. For example, a conductive pattern may be positioned within or on the substrate. The conductive pattern may be used as a first antenna (211). The substrate may include, for example, a printed circuit board (PCB), a flexible PCB (FPCB), and / or any substrate structure within the housing.

[0049] For convenience of explanation, the first antenna (211) has been described, but a similar structure can also be applied to the second antenna (213). The antennas described above are merely examples, and the embodiments of the present disclosure are not limited thereto. For example, a metal plate on the back of a display, a metallic pattern engraved on a housing, or any metal structure can be used as an antenna.

[0050] The sensor (230) may include at least one of a gesture sensor, a gyro sensor, a pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, an illuminance sensor, a proximity sensor, and / or an ultrasonic sensor.

[0051] In one example, the sensor (230) may be a sensor for detecting a change in the shape of the housing. For example, the sensor (230) may include a Hall sensor and a magnet. The Hall sensor can detect a magnetic field and a magnet placed in a specific part of the housing. The electronic device (10) can detect a change in the shape of the housing by detecting a change in the position of the magnet when the shape of the housing changes through the Hall sensor. For example, the sensor (230) may include a light sensor. The light sensor can detect a change in the amount of light collected through the light sensor or a change in the path of the light. The electronic device (10) can detect a change in the shape of the housing by detecting a change in the amount of light collected when the shape of the housing changes through the light sensor. For example, the sensor (230) may include an angle sensor. The angle sensor can be installed at the hinge portion and directly measure the angle at which the foldable device is folded. The electronic device (10) can detect a change in the shape of the housing by measuring the angle of the hinge portion when the shape of the housing changes through an angle sensor. For example, the sensor (230) may include an inertial measurement unit (IMU). The electronic device (10) can detect a change in the shape of the housing by measuring the acceleration and angular velocity that occur when the shape of the housing changes through the IMU.

[0052] The communication circuit (240) may be referred to as a radio frequency front end (RFFE). The communication circuit (240) may include at least one chip, at least one RF component, and / or at least one chipset. The communication circuit (240) may be electrically connected to at least some of the plurality of antennas (210). The communication circuit (240) may perform processing (e.g., amplification, filtering, and / or phase shifting) on ​​a signal to be transmitted via the plurality of antennas (210). The communication circuit (240) may include at least one of an amplifier, a low noise amplifier (LNA), at least one filter, a duplexer, a phase shifter, and / or a switch.

[0053] The transceiver (250) may perform post-processing on a signal received from the communication circuit (240). For example, the transceiver (250) may perform downconversion, amplification, and / or filtering on the received signal. The transceiver (250) may convert the received signal into a baseband signal and transmit it to the processor (260). The transceiver (250) may perform post-processing on a signal received from the processor (260). For example, the transceiver (250) may convert a transmission signal into a radio frequency signal and transmit it to the communication circuit (240). The transceiver (250) may process a signal based on a control signal from the processor (260).

[0054] The processor (260) may control various components of the electronic device (10) to cause the electronic device (10) to perform various operations. For example, the processor (260) may include a baseband processor that processes a baseband signal received from the communication circuit (240) or transmits a baseband signal to the communication circuit (240).

[0055] The processor (260) may be communicatively, electrically, operatively, or functionally connected to at least one or more of the sensor (230), the communication circuit (240), the transceiver (250), and / or the memory (270). In various embodiments of the present disclosure, when a component is “operatively” connected to another component, it may mean that the component is connected so as to be able to operate the other component. For example, the component may operate the other component by transmitting a control signal to the other component, either directly or via another component. In various embodiments of the present disclosure, when a component is “functionally” connected to another component, it may mean that the component is connected so as to be able to execute a function of the other component. For example, the component may execute a function of the other component by transmitting a control signal to the other component, either directly or via another component.

[0056] The processor (120) may include at least one processor. For example, the processor (120) may include an application processor (AP), a central processing unit (CPU), a graphics processing unit (GPU), a neural processing unit (NPU), a tensor processing unit (TPU), and / or a communication processor (CP). The processor (120) may include one chip or a chipset. In the present disclosure, the processor (120) may be referred to as a hardware component having an architecture by at least one processing circuit. For example, the processor (120) may be mounted on a substrate (e.g., a printed circuit board) located within the electronic device (10) and may communicate with other components of the electronic device (10) through at least one conductive path formed on the substrate.

[0057] The memory (270) can store instructions. When executed by the processor (260), the instructions can cause the electronic device (10) to perform various operations. In various embodiments of the present disclosure, the operation of the electronic device (10) can be referred to as an operation performed by the processor (120) by executing instructions stored in the memory (110). The memory (110) can be configured with hardware similar to the memory (1920) described below with reference to FIG. 19.

[0058] The memory (270) can store a plurality of tables in which maximum power reduction (MPR) values ​​are defined. For example, the memory (270) can include a non-volatile (NV) memory. "Maximum power reduction values" can be referred to as a term meaning a table defining MPR values. The "maximum power reduction value" can be referred to as a term meaning a reduction value for the "maximum transmission power" set in the electronic device (10) as one MPR value selected from the table in which MPR values ​​are defined. For example, the memory (270) can store tables in which MPR values ​​applicable to power class 2 (PC2) are defined according to a modulation scheme and resource block (RB) information (e.g., the number of resource blocks). PC2 may be a power class used in 5G NR (new radio) and LTE (long-term evolution) networks, among the power classes defined by the 3rd generation partnership project (3GPP) to manage the performance and power consumption of wireless communications. For example, PC2 may be a power class applied to smartphones, tablets, IoT devices, and / or other mobile devices. A modulation scheme may refer to a method of changing the characteristics of a carrier wave in order to transmit an analog or digital signal over a frequency band. For example, a modulation scheme may include a method of changing the phase of a carrier wave, or a method of changing both the amplitude and phase simultaneously. For example, a modulation scheme may include binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation (QAM), 64 QAM, and / or 256 QAM.A resource block (RB) may represent a basic unit for managing frequency resources. For example, a resource block may be classified into an Edge RB, an Outer RB, and / or an Inner RB, depending on the region within the frequency band where the resource block is located. Power control for each resource block may vary depending on its location. Tables defining maximum power reduction (MPR) values ​​will be described below with reference to FIGS. 13 and 15.

[0059] The memory (270) can store a plurality of adjustment values ​​that can adjust the maximum transmission power. The electronic device (10) can determine the maximum transmission power by applying a maximum transmission power reduction value (MPR) and an adjustment value to a maximum transmission power limit (MTPL). The adjustment values ​​will be described later with reference to FIGS. 14 and 16.

[0060] FIG. 3 illustrates the structure of a communication circuit of an electronic device according to one embodiment.

[0061] Referring to FIGS. 2 and 3, according to one embodiment, the transceiver (250) may be electrically connected to at least one transmit path and / or at least one receive path. For example, the communication circuit (240) may include a first transmit path (300), a first receive path (301), a second receive path (302), and a third receive path (303). The number of receive paths and the number of transmit paths illustrated in FIG. 3 are exemplary, and embodiments of the present disclosure are not limited thereto. For example, when the transceiver (250) includes a plurality of transmit ports, the communication circuit (240) may additionally include a plurality of transmit paths (e.g., a second transmit path and / or a third transmit path).

[0062] In one example, the first transmission path (300) may include at least one power amplifier (e.g., power amplifier (310)) and / or a filter circuit (320). In one example, the first transmission path (300) may be coupled to a feedback path (not shown) via a coupler. The power amplifier on the first transmission path (300) may have nonlinearity in some frequency range. Due to the nonlinearity of the power amplifier, harmonic components may be generated with respect to the frequency of the transmission signal. Due to the harmonic components, the phase modulation distortion described below may occur.

[0063] For example, the first receiving path (301) may include at least one power amplifier (e.g., a low noise amplifier, LNA) (e.g., a first power amplifier (311)) and / or a first filter circuit (321). For example, the second receiving path (302) may include at least one power amplifier (e.g., a second power amplifier (312)) and / or a second filter circuit (322). For example, the third receiving path (303) may include at least one power amplifier (e.g., a third power amplifier (313)) and / or a third filter circuit (323).

[0064] The communication circuit (240) may include a switching circuit (330). For example, the switching circuit (330) may include a diplexer, at least one switch, and / or at least one duplexer. For example, the switching circuit (330) may be configured to change connections between a receive path and a transmit path and a plurality of antennas (e.g., a first antenna (351), a second antenna (352), and / or a third antenna (353)). For example, the switching circuit (330) may be configured to change connections between a receive path and a transmit path and tuning circuits connected to the antennas (e.g., a first tuning circuit (341), a second tuning circuit (342), and / or a third tuning circuit (343)). For example, the switching circuit (330) may be configured to receive a control signal from the transceiver (250) or the processor (260) and change the connection between the communication circuit (240) and the plurality of antennas based on the received control signal.

[0065] The plurality of antennas (e.g., the plurality of antennas (210) of FIG. 2) may include a first antenna (351), a second antenna (352), and / or a third antenna (352). The first antenna (351) may be electrically connected to a first tuning circuit (341). The first tuning circuit (341) may include at least one element and / or switch for impedance control of the first antenna (351). For example, the second antenna (352) may be electrically connected to the second tuning circuit (342), and the third antenna (353) may be electrically connected to the third tuning circuit (343). The tuning circuits illustrated in FIG. 3 are examples, and at least some of the illustrated tuning circuits may be omitted. The plurality of antennas described above with respect to FIG. 3 may correspond to, for example, the antennas described below with respect to FIGS. 4A to 10.

[0066] In one example, the electronic device (10) may control tuning circuits (e.g., the first tuning circuit (341), the second tuning circuit (342), and / or the third tuning circuit (343)) to adjust the impedance of the transmitting antenna. As the electronic device (10) controls the tuning circuits, the isolation between the transmitting antennas connected to the tuning circuits may vary. For example, when the electronic device (10) transmits uplink signals using a first antenna (351) connected to the first tuning circuit (341) and a second antenna (352) connected to the second tuning circuit (342), if the first tuning circuit (341) and the second tuning circuit (342) are controlled so that the impedances of the first antenna (351) and the second antenna (352) match, signal interference may be reduced, thereby increasing the isolation. For example, when an electronic device (10) transmits uplink signals using a first antenna (351) connected to a first tuning circuit (341) and a second antenna (352) connected to a second tuning circuit (342), if the first tuning circuit (341) and the second tuning circuit (342) are controlled so that the impedances of the first antenna (351) and the second antenna (352) do not match, isolation may be reduced due to signal interference.

[0067] In one example, when the electronic device (10) transmits an uplink signal in the SISO manner, the tuning circuit can be controlled to a setting value that maximizes the antenna transmission performance. In another example, when the electronic device (10) transmits uplink signals using a plurality of transmission antennas, the tuning circuit can be controlled to a setting value that increases the isolation even if the antenna transmission performance is reduced. For example, when the isolation between the plurality of transmission antennas transmitting uplink signals decreases (for example, when the housing shape changes from the unfolded state to the folded state and the separation distance between the transmission antennas becomes closer), the electronic device (10) can control the tuning circuit to a setting value that increases the isolation to secure the isolation.

[0068] FIGS. 4A and 4B illustrate an electronic device in an unfolded form according to one embodiment, and FIG. 4C illustrates an electronic device in a folding form according to one embodiment.

[0069] Referring to FIGS. 1 and 4A to 4C, an electronic device (10a) according to one embodiment (e.g., the electronic device (10) of FIG. 1) may include a first housing (410) and a second housing (420). The first housing (410) and the second housing (420) may be arranged on both sides with respect to a folding axis (e.g., the A-axis) and may have an overall symmetrical shape with respect to the folding axis. A hinge structure (441) may be formed between the first housing (410) and the second housing (420).

[0070] The hinge structure (441) may be arranged in the x-axis direction or in the y-axis direction. Two or more hinge structures (441) may be arranged so as to be folded in the same direction or in different directions. For example, the electronic device (10a) may include a flexible display (430) (or, foldable display, first display) arranged in an area formed by a pair of housings (410, 420).

[0071] In one example, the first housing (410) and the second housing (420) may be arranged on both sides with respect to a folding axis parallel to the x-axis, and may have a shape that is substantially symmetrical with respect to the folding axis. For example, the angle or distance between the first housing (410) and the second housing (420) may vary depending on whether the electronic device (10a) is in a flat state, a folded state, or an intermediate state. Meanwhile, the definitions of the folding state, the intermediate state, or the unfolding state are examples and may be applied differently depending on various implementation examples.

[0072] The unfolding state may refer to a first state, an open state, an open state, or a flat state, as illustrated in FIGS. 4A and 4B . The unfolding state may include a state in which the flexible display is exposed by forming an angle between the first housing (410) and the second housing (420) that is greater than a specified angle (e.g., 120 degrees). For example, the unfolding state may be a state in which the angle between the first housing (410) and the second housing (420) is 180 degrees, and the first housing (410) and the second housing (420) may be arranged to face the same direction (e.g., the first direction (z-axis)). The definition of the unfolding state is an example and may be applied differently depending on various implementation examples.

[0073] The folding state may refer to a second state, a folded state, a folded state, a closed state, or a close state, as illustrated in FIG. 4C. The folding state may refer to a state in which the first housing (410) and the second housing (420) are arranged to face each other, and may refer to a state in which the electronic device (10a) is completely folded. The folding state may be a narrow angle (e.g., 0 to 5 degrees) between the first housing (410) and the second housing (420). The definition of the folding state is an example and may be applied differently depending on various implementation examples.

[0074] The electronic device (10a) may form a first display (430) (e.g., a main display) on the front of the electronic device. The first display (430) of the electronic device may refer to a flexible display in which at least a portion of the display can be transformed into a flat or curved surface. The first display (430) may be folded upward and downward based on a folding axis. At least one camera device (e.g., a first camera device (405)) may be placed on the first display (430).

[0075] The electronic device (10a) may form a second display (440) (e.g., a sub-display and / or a cover display) on at least a portion of the rear surface of the electronic device (10a). The electronic device (10a) may include a plurality of camera devices (e.g., second camera devices (415)) on the rear surface of the electronic device (10a).

[0076] The electronic device (10a) may include at least one of a microphone (403), a speaker (401, 402), a sensor module (404), a camera device (405, 415), a key input device (406), and / or a connector port (407). In the illustrated embodiment, the microphone (403), the speaker (401, 402), the sensor module (404), the camera device (405, 415), the key input device (406), or the connector port (407) refers to a hole or shape formed in the first housing (410) and / or the second housing (420), but may be defined to include an actual electronic component (e.g., an input device, an audio output device, a sensor module, and / or a camera device) disposed inside the electronic device (10a) and operating through the hole or shape.

[0077] In one example, the microphone (403) may include at least one microphone disposed in the second housing (420). For example, the microphone (403) may include a plurality of microphones disposed so as to detect the direction of sound. In some embodiments, the plurality of microphones may be disposed at appropriate locations in the first housing (410) and / or the second housing (420). The speakers (401, 402) may include a call speaker (401) (e.g., a receiver) disposed in the first housing (410) and a speaker (402) disposed in the second housing (420). The microphone (403), the speaker (401, 402), and the connector port (407) are arranged in a space provided in the first housing (410) and / or the second housing (420) of the electronic device (10a), and can be exposed to the external environment through at least one hole formed in the first housing (410) and / or the second housing (420). The at least one connector port (407) can be used to transmit and receive power and / or data with an external electronic device. For example, the at least one connector port (e.g., an ear jack hole) can accommodate a connector (e.g., an ear jack) for transmitting and receiving audio signals with the external electronic device. The hole formed in the first housing (410) and / or the second housing (420) can be used in common for the microphone (403) and the speaker (401, 402).

[0078] In one example, the sensor module (404) may generate an electrical signal or data value corresponding to an internal operating state of the electronic device (10a) or an external environmental state. The sensor module (404) may detect an external environment, for example, through a first surface (+z-axis direction) of the first housing (410). For example, the electronic device (10a) may further include at least one sensor module arranged to detect an external environment through a second surface (-z-axis direction) of the first housing (410). For example, the sensor module (404) (e.g., an illuminance sensor) may be arranged under the flexible display (430) to detect an external environment through the flexible display (430). For example, the sensor module (404) may include at least one of a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, an illuminance sensor, a proximity sensor, and / or an ultrasonic sensor.

[0079] In one example, the camera device (405, 415) may include one or more lenses, an image sensor, and / or an image signal processor (ISP). The flash may include, for example, a light emitting diode or a xenon lamp. For example, the camera device (405, 415) may be arranged such that two or more lenses (e.g., a wide-angle lens, an ultra-wide-angle lens, or a telephoto lens) and image sensors are located on one side of the electronic device (10a). For example, the camera device (205, 215) may also include lenses and / or image sensors for time of flight (TOF).

[0080] In one example, a key input device (406) (e.g., a key button) may be disposed on at least one side of the first housing (410) and / or the second housing (420). For example, the electronic device (10a) may not include some or all of the key input devices (406). The key input devices (406) that are not included may be implemented in another form, such as a soft key, on the flexible display (430). For example, the key input device (406) may be implemented using a pressure sensor included in the flexible display (430).

[0081] In one example, some of the camera devices (405, 415) (e.g., the first camera device (405)) or the sensor module (404) may be arranged to be exposed through the flexible display (430). For example, the first camera device (405) or the sensor module (404) may be arranged to be in contact with the external environment through an opening (e.g., a through hole) at least partially formed in the flexible display (430) in the internal space of the electronic device (10a). In another example, some of the sensor modules (404) may be arranged to perform their functions without being visually exposed through the flexible display (430) in the internal space of the electronic device (10a). In this case, an area of ​​the flexible display (430) facing the sensor module (404) may not require an opening.

[0082] FIG. 5 illustrates an antenna configuration of an electronic device according to one embodiment.

[0083] Referring to FIGS. 1, 4, and 5, an electronic device (10a) according to one embodiment may include a first housing (410) and a second housing (420) formed to be folded relative to each other about a folding axis.

[0084] In one example, the first housing (410) may include a metal frame made of a metal material. For example, at least a portion of the metal frame of the first housing (410) may be divided into a plurality of sections (511, 512, 513, 514, and / or 515) by a plurality of first segments (501). For example, at least some of the plurality of sections (511, 512, 513, 514, and / or 515) of the first housing (410) may be used as sub-antennas.

[0085] In one example, a part of the first part (511) of the first housing (410) can be used as a first sub-antenna (SA1), and the remaining part of the first part (511) can be used as a sixth sub-antenna (SA6). The second part (512), the third part (513), the fourth part (514), and the fifth part (515) can each be used as a second sub-antenna (SA2), a third sub-antenna (SA3), a fourth sub-antenna (SA4), and a fifth sub-antenna (SA5). For example, the electronic device can include a seventh sub-antenna (not shown). The conductive part of the seventh sub-antenna can be formed in various shapes. For example, the conductive part of the seventh sub-antenna can be engraved in a non-conductive injection-molded part of the first housing (410) using a laser direct structuring (LDS) method.

[0086] In one example, the electronic device (10a) can perform terrestrial network communication using at least one of the first sub-antenna (SA1), the second sub-antenna (SA2), the third sub-antenna (SA3), the fourth sub-antenna (SA4), the fifth sub-antenna (SA5), the sixth sub-antenna (SA6), and / or the seventh sub-antenna. The electronic device (10a) can perform terrestrial network communication using the first sub-antenna (SA1), the third sub-antenna (SA3), the fifth sub-antenna (SA5), the sixth sub-antenna (SA6), and the seventh sub-antenna. The first sub-antenna (SA1) can transmit and receive a signal in a low-band, the third sub-antenna (SA3) can transmit and receive a signal in a mid-band, and the fifth sub-antenna (SA5) and the sixth sub-antenna (SA6) can transmit and receive a signal in a mid-band and a high-band. The seventh sub-antenna can transmit and receive WiFi signals.

[0087] In one example, the second housing (420) may include a metal frame made of a metal material. For example, at least a portion of the metal frame of the second housing (420) may be divided into a plurality of sections (521, 522, and / or 523) by a plurality of second segments (502). For example, at least some of the plurality of sections (521, 522, and / or 523) of the second housing (420) may be used as a main antenna.

[0088] In one example, a portion of the seventh portion (521) of the second housing (420) can be used as a first main antenna (MA1), an eighth portion (522) can be used as a second main antenna (MA2), and a ninth portion (523) can be used as a third main antenna (MA3).

[0089] In one example, the electronic device (10a) can perform at least one of terrestrial network communication and / or non-terrestrial network (or satellite network) communication using at least one of the first main antenna (MA1), the second main antenna (MA2), and / or the third main antenna (MA3). The first main antenna (MA1) can transmit and receive signals in a low-band and a mid-band, the second main antenna (MA2) can transmit and receive signals in a high-band, and the third main antenna (MA3) can transmit and receive signals in a mid-band and a high-band.

[0090] In one example, the electronic device (10a) may transmit uplink signals in a SISO manner using one antenna among the first sub-antenna (SA1), the second sub-antenna (SA2), the third sub-antenna (SA3), the fourth sub-antenna (SA4), the fifth sub-antenna (SA5), the sixth sub-antenna (SA6), the seventh sub-antenna, the first main antenna (MA1), the second main antenna (MA2), and / or the third main antenna (MA3). In one example, the electronic device (10a) may transmit uplink signals in a MIMO manner or a MISO manner using at least two antennas among the first sub-antenna (SA1), the second sub-antenna (SA2), the third sub-antenna (SA3), the fourth sub-antenna (SA4), the fifth sub-antenna (SA5), the sixth sub-antenna (SA6), the seventh sub-antenna, the first main antenna (MA1), the second main antenna (MA2), and / or the third main antenna (MA3).

[0091] The antennas described above with respect to FIG. 5 are an example of the plurality of antennas (210) of FIG. 2. As described below with respect to FIG. 6, the separation distance between the antennas may change depending on changes in the shape of the electronic device (10a).

[0092] FIG. 6 illustrates antennas of an electronic device whose separation distance changes according to a change in housing shape according to one embodiment.

[0093] Referring to FIGS. 1, 4, 5, and 6, the electronic device (10a) may include a first housing (410), a second housing (420), a first antenna (601) (e.g., the third sub-antenna (SA3) of FIG. 5), and / or a second antenna (602) (e.g., the second main antenna (MA2) of FIG. 5). In one example, the electronic device (10a) may be a foldable type or a flexible type electronic device (10a). The shape of the electronic device (10a) may include a first shape (S1) and a second shape (S2) depending on changes in the shape of the housing. The first shape (S1) may include an unfolded shape, a spread shape, an open shape, an open shape, and / or a flat (or flat) shape. The second form (S2) may include a folded form, a folded form, a closed form, and / or a closed form. With respect to the first form (S1) and the second form (S2), reference may be made to the contents described above in FIGS. 4A to 4C.

[0094] In the first form (S1), the first antenna (601) may be disposed on one side of the first housing (410). The first antenna (601) may be disposed on one side of the first housing (410) that is located away from the second housing (420). The second antenna (602) may be disposed on one side of the second housing (420). The second antenna (602) may be disposed on a corner of one side of the second housing (420) that is located away from the first housing (410).

[0095] In one example, the separation distance may refer to the physical distance between the two antennas. For example, the separation distance may include a value obtained by measuring the length of a line segment connecting the center points of the two antennas. For example, the separation distance between the first antenna and the second antenna may include a value obtained by measuring the length of a line segment connecting a point of the first antenna and a point of the second antenna such that the physical distance between the two antennas is the minimum value. In the first form (S1), the separation distance between the first antenna (601) and the second antenna (602) may be greater than the separation distance between the first antenna (601) and the second antenna (602) in the second form (S2). In the second form (S2), the electronic device (10a) may be in a folding form. In the second form, the separation distance between the first antenna (601) and the second antenna (602) may be closer than in the first form (S1).

[0096] In one example, the greater the separation between multiple antennas used for MIMO or MISO transmission, the greater the isolation. Isolation may refer to a performance indicator indicating how well signal interference between antennas is prevented. For example, the greater the isolation, the less the signal interference between two antennas used for MIMO or MISO transmission. On the other hand, the smaller the isolation, the greater the signal interference between two antennas used for MIMO or MISO transmission. For example, if the isolation between two antennas is small, interference may occur between the signals transmitted by each antenna, resulting in signal distortion (e.g., reverse IMD (intermodulation distortion)). Reverse IMD may refer to a distortion phenomenon that occurs when a signal is reflected from an output port or when a signal enters the output port in reverse. For example, if the isolation between two wireless signal paths is insufficient, IMD generated from a power amplifier of one transmission path may be amplified by the other power amplifier, degrading the quality of the transmitted signal.

[0097] In one example, the electronic device (10a) may be configured to limit the transmission power to reduce signal distortion (e.g., reverse IMD). The electronic device (10a) may set the transmission power to be limited differently in the first configuration and the second configuration. For example, the isolation between the first antenna (601) and the second antenna (602) in the second configuration (S2) may be smaller than the isolation between the first antenna (601) and the second antenna (602) in the first configuration (S1). In the second configuration (S2), the electronic device (10a) may limit the transmission power for uplink signal transmission more than in the first configuration (S1). When the transmission power is limited, the signal distortion phenomenon can be prevented or reduced even if the isolation between the first antenna (601) and the second antenna (602) is small. In the case of the first form (S1), since the isolation between the first antenna (601) and the second antenna (602) is sufficient even without significantly limiting the transmission power, there may be no signal distortion or the signal distortion may be less than in the second form (S2). In the case of the first form (S1), since the transmission power does not have to be significantly limited, the performance (e.g., signal strength, signal-to-noise ratio (SNR), and / or network coverage) of the electronic device (10a) associated with wireless signal transmission may be improved compared to the second form (S2).

[0098] FIG. 7a illustrates an electronic device in a closed form and an electronic device in an open form according to one embodiment, and FIG. 7b illustrates an electronic device in a closed form according to one embodiment.

[0099] Referring to FIGS. 1, 7a, and 7b, an electronic device (10b) (e.g., the electronic device (10) of FIG. 1) according to one embodiment may include a first housing (710) (or a sliding structure, a sliding housing, a sliding case, and / or a sliding body), a second housing (720) (or a fixed structure, a fixed housing, a fixed case, or a main body), and / or a display (730).

[0100] In one example, the electronic device (10b) may be a slidable type or a rollable type electronic device, and its shape may be changed by the movement of the first housing (710) with respect to the second housing (720). For example, the shape of the electronic device (10b) may include a first shape (S1) and a second shape (S2). The first shape (S1) may include a closed mode, a reduced mode, a slide-in mode, and / or a minimum size mode. The second shape (S2) may include an open mode, an expanded mode, a slide-out mode, and / or a maximum size mode. The first shape (S1) and the second shape (S2) of the electronic device (10b) may be determined according to the relative position of the first housing (710) with respect to the second housing (720). The electronic device (10b) may be capable of transforming (or switching) between a first form (S1) and a second form (S2) by a user's operation or mechanical operation (e.g., a motor).

[0101] In one example, the first form (S1) may mean a form in which the area (or size) of the exposure area of ​​the display (730) exposed to (or forming the front) of the electronic device (10b) (e.g., the surface facing the +z-axis direction) is relatively reduced. The second form (S2) may mean a form in which the area (or size) of the exposure area of ​​the display (730) exposed to (or forming the front) of the electronic device (10b) is relatively expanded. For example, the first form (S1) may mean a form in which the exposure area of ​​the display (730) exposed to the front of the electronic device (10b) is the minimum size, and the second form (S2) may mean a form in which the exposure area of ​​the display (730) exposed to the front of the electronic device (10b) is the maximum size. Although not shown, the electronic device (10b) may further include at least one intermediate state (e.g., a partially expanded state and / or a partially open state) defined as a state between the first state (S1) and the second state (S2). For example, the at least one intermediate state may mean one or more states in which the size of the exposed area of ​​the display (730) is larger than that of the first state (S1) and smaller than that of the second state (S2).

[0102] In one example, the first form (S1) may mean that the first housing (710) is in a closed state with respect to the second housing (720) by having a part of the first housing (710) located inside the second housing (720). The second form (S2) may mean that the first housing (710) is in an open state with respect to the second housing (720) by having a part of the first housing (710) that was inside the second housing (720) in the first form (S1) come out from the second housing (720).

[0103] In one example, the first housing (710) and the second housing (720) may be coupled to be able to slide relative to each other. The first housing (710) may be slidably coupled to one side of the second housing (720). For example, the second housing (720) may be a relatively fixed structure, and the first housing (710) may be a structure that is able to move relative to the second housing (720). The first housing (710) may be coupled to one side of the second housing (720) so as to be able to slide relative to the second housing (720) in both directions (D1, D2) (e.g., in the +y / -y axis directions).

[0104] In one example, the first housing (710) may be provided to change the shape of the electronic device (10b) by sliding relative to the second housing (720). For example, the electronic device (10b) may be changed from a first shape (S1) to a second shape (S2) by moving the first housing (710) relative to the second housing (720) in a first direction (D1) (or, a withdrawal direction). Conversely, the electronic device (10b) may be changed from a first shape (S1) to a second shape (S2) by moving the first housing (710) relative to the second housing (720) in a second direction (D2) (or, a retraction direction) opposite to the first direction (D1).

[0105] In one example, the display (730) may change the size of the exposed area visually exposed to the front of the electronic device (10b) in response to the sliding motion of the first housing (710). The display (730) may include at least a partially flexible portion. For example, the display (730) may be a flexible display. The display (730) may be configured such that the area exposed to the front of the electronic device (10b) expands or contracts by at least a portion rotating and linearly moving in response to the sliding motion of the first housing (710).

[0106] In one example, the display (730) may include a first screen area (731) and a second screen area (732) extending from the first screen area (731). The first screen area (731) may form the front surface of the electronic device (10b). For example, the first screen area (731) may be maintained in a form exposed to the front surface of the electronic device (10b) regardless of the shape of the electronic device (10b). The second screen area (732) may form the front surface of the electronic device (10b) in a form in which the size of the electronic device (10b) is expanded from the first shape (S1). For example, whether the second screen area (732) is exposed to the front surface of the electronic device (10b) may be determined based on the shape of the electronic device (10b). The second screen area (732) can be brought into or accommodated (e.g., slide-in) into the interior of the first housing (710) or pulled out or exposed (e.g., slide-out) to the exterior of the first housing (710) as the first housing (710) moves.

[0107] In one example, the second screen area (732) may have a variable area exposed to the front of the electronic device (10b) depending on the relative position of the first housing (710) with respect to the second housing (720). For example, as the first housing (710) moves in the first direction (D1) from the first form (S1), the size of the second screen area (732) exposed to the front of the electronic device (10b) may gradually increase. The second screen area (732) may have a larger exposed area as the distance by which the first housing (710) moves in the first direction (D1) from the first form (S1) increases. In one embodiment, the first screen area (731) may be understood as a basic area, a fixed area, or a main area, and the second screen area (732) may be understood as an extended area, a variable area, or a sub area.

[0108] In one example, the second screen area (732) may extend in one direction from the first screen area (731). For example, the direction in which the second screen area (732) extends from the first screen area (731) may be substantially different from the direction in which the first housing moves (e.g., the first direction D1) when the electronic device (10b) is expanded. For example, the second screen area (732) may extend in the second direction D2 from the first screen area (731). The second screen area (732) may be drawn into the interior of the second housing (720) (e.g., a slide-in operation) or drawn out of the exterior of the second housing (720) (e.g., a slide-out operation) as the first housing (710) slides relative to the second housing (720).

[0109] In one example, the first screen area (731) and the second screen area (732) of the display (730) can be distinguished based on whether they are exposed to the front of the electronic device (10b) in the first form (S1). For example, the first screen area (731) may refer to a portion of the entire area of ​​the display (730) that is visually exposed to the front of the electronic device (10b) when in the first form (S1). The second screen area (732) may refer to another portion of the entire area of ​​the display (730) that is not exposed to the front of the electronic device (10b) by being located inside the first housing when in the first form (S1), and that, when transformed from the first form (S1) to the second form (S2), at least a portion of which protrudes from the inside of the first housing and is exposed to the front of the electronic device (10b). For example, the second screen area (732) may be understood to refer to the remaining area of ​​the entire display (730) excluding the first screen area (731). In one embodiment disclosed in this document, the first screen area (731) and the second screen area (732) of the display (730) are not physically distinct areas, and do not mean that they have different shapes or properties.

[0110] In one example, the first form (S1) may be a form in which the front of the electronic device (10b) is formed by the first screen area (731), and the second screen area (732) is located inside the first housing (710). The second form (S2) may be a form in which the front of the electronic device (10b) is formed by at least a portion of the second screen area (732) and the first screen area (731). For example, the second form (S2) may mean a form in which the area of ​​the second screen area (732) exposed to the front of the electronic device (10b) is the largest. Although not shown, one or more intermediate forms between the first form (S1) and the second form (S2) may mean a form in which the area of ​​the second screen area (732) exposed to the front of the electronic device (10b) is smaller than that of the second form (S2).

[0111] In one example, the display (730) may be exposed to the front of the electronic device (10b) and may form a screen display area on which predetermined visual information (or, screen) is displayed. For example, in the first form (S1), the screen display area may be formed by the first screen area (731). In the second form (S2), the screen display area may be formed by a portion of the second screen area (732) and the first screen area (731). The electronic device (10b) may provide a screen display area that is expanded in the second form (S2) compared to the first form (S1). For example, the screen display area may be substantially the same as the exposure area of ​​the display (730), or may be smaller than the exposure area.

[0112] In one example, the display (730) may not be exposed on the back of the electronic device (10b). FIG. 7b may illustrate the back when the electronic device (10b) is in the first form (S1). The electronic device (10b) may include a camera device and / or a sensor module on the back of the electronic device (10b). The camera device and / or sensor module may be arranged on the back of the first housing (710). When the electronic device (10b) is in the second form (S2), the back may be described later with reference to FIG. 8.

[0113] Figure 8 illustrates an antenna configuration of an electronic device in one embodiment.

[0114] Referring to FIGS. 1, 7A, 7B, and 8, an electronic device (10b) according to one embodiment (e.g., the electronic device (10) of FIG. 1) may be a slidable type or a rollable type electronic device. A first housing (710) may be provided to change the shape of the electronic device (10b) by sliding relative to a second housing (720). For example, the electronic device (10b) may be changed from a first shape (S1 of FIG. 7A) to a second shape (S2 of FIG. 7A) by moving the first housing (710) relative to the second housing (720) in a first direction (D1 of FIG. 7A) (or, in a withdrawal direction). FIG. 8 may illustrate a rear portion of the electronic device (10b) when it is in the second shape (S2 of FIG. 7A). For example, when the first housing (710) in the first form (S1 of FIG. 7a) moves in the first direction (D1 of FIG. 7a) (or, the withdrawal direction) with respect to the second housing (720), a metal connecting portion connecting the first housing (710) and the second housing (720) may be exposed as much as the first housing (710) moves with respect to the second housing (720). For example, whether or not the connecting portion is exposed to the rear of the electronic device (10b) may be determined depending on the form of the electronic device (10b). The connecting portion may be introduced or accommodated (e.g., slide-in) into the interior of the first housing (710), or may be introduced or exposed (e.g., slide-out) to the exterior of the first housing (710) depending on the movement of the first housing (710).

[0115] In one example, the first housing (710) may include a metal frame made of a metal material. For example, at least a portion of the metal frame of the first housing (710) may be divided into a plurality of sections (811, 812, 813, 814, 815, 816, and / or 817). Some of the sections (811, 812, 813, 814, 815, 816, and / or 817) of the first housing (710) may have overlapping areas with other sections. At least some of the sections (811, 812, 813, 814, 815, 816, and / or 817) of the first housing (710) may be used as sub-antennas.

[0116] In one example, each of the first portion (811), the second portion (812), the third portion (813), the fourth portion (814), the fifth portion (815), the sixth portion (816), and / or the seventh portion (817) of the first housing (710) can be used as a first sub-antenna (SA1), a second sub-antenna (SA2), a third sub-antenna (SA3), a fourth sub-antenna (SA4), a fifth sub-antenna (SA5), a sixth sub-antenna (SA6), and / or a seventh sub-antenna (SA7). At least some of the antennas among the first sub-antennas (SA1) to the seventh sub-antennas (SA7) can include conductive portions of various shapes. For example, at least some of the antennas can include conductive portions engraved in an LDS manner on a non-conductive injection-molded portion of a portion of the first housing (710).

[0117] In one example, the electronic device (10b) may perform terrestrial network communication using at least one of a first sub-antenna (SA1), a second sub-antenna (SA2), a third sub-antenna (SA3), a fourth sub-antenna (SA4), a fifth sub-antenna (SA5), a sixth sub-antenna (SA6), and / or a seventh sub-antenna (SA7). For example, at least some of the antennas among the first to seventh sub-antennas (SA1) to (SA7) may transmit and receive at least one signal of a low-band, a mid-band, a high-band, and / or Wi-Fi.

[0118] In one example, the electronic device (10b) may perform non-terrestrial network (or satellite network) communication using at least one of the first sub-antenna (SA1), the second sub-antenna (SA2), the third sub-antenna (SA3), the fourth sub-antenna (SA4), the fifth sub-antenna (SA5), the sixth sub-antenna (SA6), and / or the seventh sub-antenna (SA7). For example, at least some of the antennas among the first sub-antenna (SA1) to the seventh sub-antenna (SA7) may transmit and receive signals in a satellite communication band.

[0119] In one example, at least some of the antennas among the first sub-antenna (SA1) to the seventh sub-antenna (SA7) can be used for reception and can be DRX (diversity reception) antennas. In one example, at least some of the antennas among the first sub-antenna (SA1) to the seventh sub-antenna (SA7) can be used for both transmission and reception and can be PRX (primary receive) antennas.

[0120] In one example, the second housing (720) may include a metal frame made of a metal material. For example, at least a portion of the metal frame of the second housing (720) may be divided into a plurality of sections (821, 822, 823, 824, and / or 825). Some of the sections (821, 822, 823, 824, and / or 825) may have overlapping areas with other sections. At least some of the sections (821, 822, 823, 824, and / or 825) of the second housing (720) may be used as a main antenna.

[0121] In one example, each of the eighth portion (821), the ninth portion (822), the tenth portion (823), the eleventh portion (824), and / or the twelfth portion (825) of the second housing (820) can be used as a first main antenna (MA1), a second main antenna (MA2), a third main antenna (MA3), a fourth main antenna (MA4), and / or a fifth main antenna (MA5).

[0122] In one example, the electronic device (10b) can perform at least one of terrestrial network communication and / or non-terrestrial network (or satellite network) communication using at least one of the first main antenna (MA1) to the fifth main antenna (MA5). For example, at least some of the antennas of the first main antenna (MA1) to the fifth main antenna (MA5) can transmit and receive at least one signal of a low-band, a mid-band, a high-band, and / or Wi-Fi.

[0123] In one example, the electronic device (10b) can transmit uplink signals in a SISO manner using one of the first to seventh sub-antennas (SA1) and / or the first to fifth main antennas (MA1) and / or the fifth main antennas (MA5). In one example, the electronic device (10b) can transmit uplink signals in a MIMO manner or a MISO manner using at least two or more of the first to seventh sub-antennas (SA7) and / or the first to fifth main antennas (MA1) and / or the fifth main antennas (MA5).

[0124] In one example, the electronic device (10b) may be configured to limit the transmission power to reduce signal distortion (e.g., reverse IMD). As described above with reference to FIGS. 7a and 7b , the electronic device (10b) may set the transmission power to be limited differently in the first configuration (S1) and the second configuration (S2).

[0125] FIG. 9A is a perspective view of the front of an electronic device according to one embodiment. FIG. 9B is a plan view of the rear of an electronic device according to one embodiment.

[0126] Referring to FIGS. 9A and 9B , an electronic device (10c) (e.g., the electronic device (10) of FIG. 1 ) may be foldably coupled to each other with respect to a folding axis (F) through at least one hinge device (940) (e.g., a hinge module or a hinge structure), and may include a first housing (910) (e.g., a first housing structure) including a first side member (913) (e.g., a side bezel) and a second housing (920) (e.g., a second housing structure) including a second side member (923) (e.g., a side bezel). For example, the first housing (910) and the second housing (920) may be configured as a foldable housing (e.g., a housing structure). For example, the electronic device (10c) may include a first display (930) (e.g., a flexible display, a foldable display, or a main display) arranged to be supported by a first housing (910) and a second housing (920). For example, the first housing (910) may include a first side (911) and a second side (912) facing in an opposite direction (e.g., in the -z-axis direction) of the first side (911). For example, the second housing (920) may include a third side (921) and a fourth side (922) facing in an opposite direction (e.g., in the -z-axis direction) of the third side (921). For example, the first housing (910) may include a first rear cover (914) coupled with a first side member (913). For example, the second housing (920) may include a second rear cover (924) coupled with a second side member (923). For example, when the electronic device (10c) is in a fully unfolded first configuration (e.g., an unfolded state or an unfolded state), the first side (911) and the third side (921) may be operated so that they face substantially the same direction (e.g., a z-axis direction). For example, when the electronic device (10c) is in a fully folded second configuration (e.g., a folded state or a folded state), the first side (911) and the third side (921) may face each other or face opposite directions.For example, the electronic device (10c) may be operated to maintain a third state (e.g., an intermediate state) between the first state and the second state.

[0127] According to one embodiment, the electronic device (10c) may include a first receiver (901), at least one first sensor module (904) (e.g., an ambient light sensor) and / or at least one first camera module (905) (e.g., a UDC, under display camera) disposed on a first side (911) of the first housing (910). For example, the electronic device (10c) may include at least one key (906) disposed on a first side member (913). For example, the electronic device (10c) may include at least one second camera module (908) and / or a flash (909) disposed on a second side (912) of the first housing (910) (e.g., a first rear cover (914)). For example, the electronic device (10c) may include a second display (931) disposed on a fourth side (922) of the second housing (920), at least one third camera module (925) (e.g., UDC, under display camera), at least one second sensor module (926), and / or a second receiver (927). For example, the second display (931) may be disposed to be visible from the outside through at least a portion of the second rear cover (924). For example, the electronic device (10c) may include a speaker (902) disposed on the second side member (923), a microphone (903) disposed on the first side member (913), and / or a connector port (907). At least some of the components described above may be disposed in the first housing (910) and / or the second housing (920).

[0128] According to one embodiment, the first display (930) (e.g., a flexible display) may include a first area (930a) (e.g., a first planar portion) corresponding to at least a portion of the first surface (911), a second area (930b) (e.g., a second planar portion) corresponding to at least a portion of the third surface (921), and a third area (930c) (e.g., a flexible portion) connecting the first area (930a) and the second area (930b) and allowing the electronic device (10c) to be deformed into a second shape (e.g., a folded shape) and / or a third shape. For example, the third area (930c) may be positioned to at least partially overlap at least one hinge device (940) when the first display (930) is viewed from above (e.g., in the z-axis direction). For example, the first display (930) may be arranged so that it is not visible from the outside in the second form by having the first side (911) and the third side (921) face each other (e.g., inward-fold type). For example, the first display (930) may be arranged so that it is visible from the outside in the second form by having the first side (911) and the third side (921) face each other in opposite directions (e.g., outward-fold type).

[0129] FIG. 10 illustrates an antenna configuration of an electronic device according to one embodiment.

[0130] Referring to FIGS. 1 and 10 , the electronic device (10c) may include a first housing (1010), a second housing (1020), a first antenna (1001), a second antenna (1002), a third antenna (1003), and / or a fourth antenna (1004). The first housing (1010) and the second housing (1020) may correspond to the first housing (910) and the second housing (920) of FIGS. 9A and 9B , respectively. The structure of the electronic device (10c) illustrated in FIG. 10 is exemplary, and the embodiments of the present document are not limited thereto. For example, the electronic device (10c) may further include configurations not illustrated in FIG. 10 (e.g., the configuration of the electronic device (10c) of FIGS. 9A and 9B ).

[0131] In one example, the electronic device (10c) may be a foldable type or a flexible type electronic device (10c). The shape of the electronic device (10c) may change depending on a change in the shape of the housing. For example, the shape of the electronic device (10c) may include a folding shape and / or an unfolding shape depending on a change in the shape of the housing. Even if the shape of the housing changes, the distance between the plurality of antennas (1001, 1002, 1003, and / or 1004) arranged in the electronic device (10c) may not change. For example, multiple antennas (1001, 1002, 1003, and / or 1004) may all be disposed in the same housing, and even if the shape of the housing changes, the spacing between the multiple antennas (1001, 1002, 1003, and / or 1004) disposed in the same housing may remain the same. For example, when multiple antennas (1001, 1002, 1003, and / or 1004) are all disposed in the first housing (1010), the spacing between the multiple antennas (1001, 1002, 1003, and / or 1004) in the folded form and the unfolded form may be the same.

[0132] In one example, if the separation distance between the plurality of antennas (1001, 1002, 1003, and / or 1004) does not change despite a change in the shape of the housing, the isolation between the plurality of antennas (1001, 1002, 1003, and / or 1004) may also not change. In one example, if there is no change in isolation due to a change in the housing shape, the electronic device (10c) may not need to apply the MPR differently for each housing shape to improve the quality of the transmitted signal (e.g., adjacent channel leakage ratio (ACLR) and / or error vector magnitude (EVM)) or the performance of the electronic device (10c) associated with wireless signal transmission (e.g., signal strength, signal-to-noise ratio (SNR) and / or network coverage). In one example, if there is no change in isolation due to a change in the housing shape, the electronic device (10c) may control the transmission power associated with the uplink transmission to the same maximum transmission power in the first shape (e.g., unfolded shape) and the second shape (e.g., folded shape).

[0133] In one example, the plurality of antennas (1001, 1002, 1003, and / or 1004) can be used to transmit uplink signals in a SISO manner. In one example, the plurality of antennas (1001, 1002, 1003, and / or 1004) can be used to transmit uplink signals in a MIMO manner or a MISO manner. For example, the electronic device (10c) can transmit uplink signals in a MIMO manner (e.g., 4x4 MIMO) or a MISO manner using all of the plurality of antennas (1001, 1002, 1003, and / or 1004). For example, the electronic device (10c) can transmit uplink signals in a MIMO scheme (e.g., 2×2 MIMO) or a MISO scheme by combining two antennas among the plurality of antennas (1001, 1002, 1003, and / or 1004). When combining two antennas among the plurality of antennas for transmitting uplink signals in the MIMO scheme or the MISO scheme, the separation distance between the antennas may vary depending on the combination of the antennas. For example, the separation distance between the antennas may be greater when the first antenna (1001) and the second antenna (1002) are used than when the first antenna (1001) and the third antenna (1003) are used to transmit uplink signals in the MIMO scheme or the MISO scheme.

[0134] FIG. 11 illustrates a configuration of an electronic device for combining transmitting antennas according to one embodiment.

[0135] Referring to FIGS. 2 and 11, the electronic device (10) can select an antenna combination to be used for MIMO or MISO transmission. In one example, the electronic device (10) can transmit uplink signals using a MIMO scheme (e.g., 2Tx (transmission) MIMO) or a MISO scheme (e.g., 2Tx (transmission) MISO) using two transmission antennas. For example, the electronic device (10) can connect two antennas to be used for uplink signal transmission among a plurality of antennas (1151, 1152, 1153, and / or 1154) through a switch circuit (1131, 1132) to a path (e.g., 1101, 1102, 1103, and / or 1104) for signal transmission. In the example of FIG. 11, the paths for signal transmission (e.g., 1101, 1102, 1103, and / or 1104) may correspond to the first transmission path (300) of FIG. 3. Additionally, the switch circuits (1131, 1132) may correspond to the switch circuit (330) of FIG. 3.

[0136] In one example, the transceiver (250) may be connected to a plurality of paths (e.g., 1101, 1102, 1103, and / or 1104) for transmitting and receiving wireless communication signals. The first path (1101) may include, for example, a path capable of receiving a radio frequency (RF) signal. For example, the first path (1101) may include a diversity reception (DRx) path. The electronic device (10) may combine signals received through multiple diversity reception paths to improve signal reception quality, and a signal collected through the first path (1101) may be combined with a signal collected through another diversity reception path to improve signal reception quality. The second path (1102) may include, for example, a path capable of transmitting and receiving an RF signal. For example, the second path (1102) can operate as a primary receive path (PRx) or a first transmit path (Tx1). The third path (1103) can include, for example, a path capable of transmitting and receiving RF signals. For example, the third path (1103) can operate as a primary receive path or a second transmit path (Tx2). The fourth path (1104) can include, for example, a path capable of receiving RF signals. For example, the fourth path (1104) can include a diversity receive path. The electronic device (10) can combine signals received through multiple diversity receive paths to improve signal reception quality, and a signal collected through the fourth path (1104) can be combined with a signal collected through another diversity receive path to improve signal reception quality.

[0137] In one example, the first switch circuit (1131) may include a double pole double throw (DPDT) switch. For example, the first switch circuit (1131) may connect the first path (1101) to the first antenna (1151) and the second path (1102) to the second antenna (1152), or may connect the first path (1101) to the second antenna (1152) and the second path (1102) to the first antenna (1151). For example, the electronic device (10) may switch the signal path and / or antenna so that the RF signal can be transmitted to the appropriate path via the first switch circuit (1131). In one example, the second switch circuit (1132) may include a DPDT switch. For example, the second switch circuit (1132) may connect the third path (1103) to the third antenna (1153) and the fourth path (1104) to the fourth antenna (1154), or may connect the third path (1103) to the fourth antenna (1154) and the fourth path (1104) to the third antenna (1153). For example, the electronic device (10) may switch the signal path and / or antenna so that the RF signal can be transmitted to the appropriate path via the second switch circuit (1132).

[0138] In one example, the first switch circuit (1131) can connect the first transmission path (Tx1) to the first antenna (1151) or to the second antenna (1152). In one example, the second switch circuit (1132) can connect the second transmission path (Tx2) to the third antenna (1153) or to the fourth antenna (1154). In one example, the electronic device (10) can use at least one combination of the first antenna combination (the first antenna and the third antenna), the second antenna combination (the first antenna and the fourth antenna), the third antenna combination (the second antenna and the third antenna), and / or the fourth antenna combination (the second antenna and the fourth antenna) to transmit uplink signals in a MIMO manner or a MISO manner through the first switch circuit (1131) and the second switch circuit (1132). As described later in FIG. 12, the isolation between antennas may vary depending on the antenna combination used for uplink signal transmission.

[0139] In one example, the transceiver (250) may include a frequency adjustment function for Tx hopping. Tx hopping may refer to a technique for reducing interference by quickly changing the transmission frequency path. For example, the transceiver (250) may further include additional components for implementing a frequency switching mechanism (e.g., a voltage-controlled oscillator (VCO) and / or a frequency synthesizer). Although the embodiments described in the present disclosure describe four combinations of transmit antennas that can be combined using two switch circuits, this is exemplary and the embodiments of the present disclosure are not limited thereto. For example, the electronic device (10) may connect the first transmission path (Tx1) to the third antenna (1153) or the fourth antenna (1154), or connect the second transmission path (Tx2) to the first antenna (1151) or the second antenna (1152), using one switch circuit having four input ports and four output ports.

[0140] FIG. 12 illustrates an antenna configuration of an electronic device according to one embodiment.

[0141] Referring to FIGS. 1 and 12 , the electronic device (10) may include a first antenna (1201), a second antenna (1202), a third antenna (1203), and / or a fourth antenna (1204). The electronic device (10) may use two of the first antenna (1201), the second antenna (1202), the third antenna (1203), and / or the fourth antenna (1204) to transmit uplink signals in a MIMO or MISO manner. Isolation between the antennas may vary depending on the combination of antennas used to transmit the uplink signals. For example, the isolation between the first antenna (1201) and the second antenna (1202) may be 15 dB. In another example, when the first antenna (1201) and the third antenna (1203) are used to transmit uplink signals, the isolation may be 5 dB. In another example, when the first antenna (1201) and the fourth antenna (1204) are used to transmit uplink signals, the isolation may be 10 dB. In another example, when the second antenna (1202) and the third antenna (1203) are used to transmit uplink signals, the isolation may be 7 dB. In another example, when the second antenna (1202) and the fourth antenna (1204) are used to transmit uplink signals, the isolation may be 5 dB. In another example, when the third antenna (1203) and the fourth antenna (1204) are used to transmit uplink signals, the isolation may be 10 dB.

[0142] In one example, the electronic device (10) may be configured so that, when the isolation between antennas used for uplink signal transmission is below a specified value, the antennas having the isolation below the specified value cannot be used for uplink signal transmission. As described above with respect to FIGS. 11 and 12 , even when the shape of the electronic device (10) does not change, the value of the isolation between the antennas may change depending on the combination of the antennas. In the following disclosure, methods for setting the maximum transmission power based on changes in the shape of the electronic device (10) are described, but those skilled in the art will understand that the method for setting the maximum transmission power described below can also be applied by changing the combination of antennas.

[0143] Figure 13 is a flowchart of a method for applying different MPR values ​​depending on the shape of a housing according to one embodiment.

[0144] The operations described below with reference to FIG. 13 may be referred to as operations of the electronic device (10) of FIG. 1. The order of the operations described below with reference to FIG. 13 is merely an example, and embodiments of the present disclosure are not limited thereto. For example, at least some of the operations may be executed differently from the order of FIG. 13, or may be executed substantially simultaneously with other operations of FIG. 13. At least some of the operations described below with reference to FIG. 13 may be omitted.

[0145] Referring to FIGS. 2 and 13, in operation 1305, the electronic device (10) may determine whether to transmit uplink signals using a plurality of transmit antennas. For example, when the electronic device (10) transmits uplink signals using at least two antennas among the plurality of antennas (210), the electronic device (10) may determine that the uplink signals are transmitted using the plurality of transmit antennas. For example, the case of transmitting uplink signals using the plurality of transmit antennas may include the case of transmitting uplink signals using the MIMO method and the case of transmitting uplink signals using the MISO method. For example, when the electronic device (10) transmits uplink signals using one antenna among the plurality of antennas (210), the electronic device (10) may determine that the uplink signals are transmitted using the SISO method. The electronic device (10) may determine whether to transmit uplink signals using the plurality of transmit antennas based on wireless resource information allocated from the network. Although the plurality of antennas (210) illustrated in FIG. 2 are illustrated as including a first antenna (211) and / or a second antenna (213), embodiments of the present disclosure are not limited thereto. For example, the plurality of antennas (210) may further include at least one of a third antenna and / or a fourth antenna. If the electronic device (10) determines that it transmits uplink signals using the plurality of transmit antennas (e.g., operation 1305-YES), the electronic device (10) may perform operation 1310. If the electronic device (10) determines that it does not transmit uplink signals using the plurality of transmit antennas (e.g., operation 1305-NO), the electronic device may perform operation 1315.

[0146] In operation 1310, the electronic device (10) can determine (e.g., identify) the shape of the housing using the sensor (230). In one example, the shape of the housing can include a first shape (e.g., an unfolded shape, the first shape (S1) described above with respect to FIGS. 4A to 10) and a second shape (e.g., a folded shape, the second shape (S2) described above with respect to FIGS. 4A to 10). With respect to the first shape and the second shape, reference can be made to the contents described above with respect to FIGS. 4A to 4C, 7A, and 7B. The sensor (230) for detecting the shape of the housing can include a Hall sensor, a proximity sensor, a light sensor, and / or an angle sensor, as described above with respect to FIG. 2. For example, the electronic device (10) can detect a change in the shape of the housing according to the contents described above with respect to FIG. 2. For example, the electronic device (10) may be determined to be in the first configuration when the angle formed by the first housing (410 or 910) and the second housing (420 or 920) or the angle of the hinge portion indicates a specified angle or greater. For example, the electronic device (10) may be determined to be in the second configuration when the angle formed by the first housing (410 or 910) and the second housing (420 or 920) or the angle of the hinge portion indicates a specified angle or less.

[0147] If the electronic device (10) determines that the shape of the housing is the first shape (e.g., operation 1310-first shape), the electronic device (10) can perform operation 1320. If the electronic device (10) determines that the shape of the housing is the second shape (e.g., operation 1310-second shape), the electronic device can perform operation 1325.

[0148] In operation 1315, the electronic device (10) may determine the third maximum transmission power by applying one of the third maximum power reduction values. Unlike the case where uplink signals are transmitted using multiple transmission antennas, when transmitting an uplink signal in the SISO manner, since there is only one transmission antenna, even if the shape of the housing changes, there may be no need to apply different maximum power reduction values ​​(or MPR) according to the housing shape. When transmitting an uplink signal in the SISO manner, the electronic device (10) may apply the same maximum power reduction value (or MPR) without identifying the shape of the housing. In FIG. 13, “third maximum power reduction values” may be referred to as a term meaning a table in which MPR values ​​applied when transmitting an uplink signal in the SISO manner are defined. In one example, the third maximum power reduction values ​​may be stored in the memory (270). For example, when transmitting an uplink signal in the SISO manner, the memory (270) may store a table (e.g., third maximum power reduction values) defining MPR values ​​applicable to power class 2 (PC2) according to a modulation scheme and a resource block (RB). In one example, when the modulation scheme and the resource block are the same conditions, the third maximum power reduction values ​​may include values ​​smaller than maximum power reduction values ​​(e.g., first maximum power reduction values ​​and second maximum power reduction values) applied when transmitting uplink signals using a plurality of transmission antennas.

[0149] In FIG. 13, the term "third maximum transmit power" may be referred to as the maximum transmit power applicable when transmitting an uplink signal in SISO mode. Maximum transmit power and maximum transmit power limit (MTPL) may be referred to as distinct terms.

[0150] For example, the maximum transmit power limit (MTPL) may refer to a limit of the maximum transmit power of the electronic device (10) set by a country, regulatory agency, or network. For example, if the MTPL set by a specific country is 23 dBm, the upper limit of the power that the electronic device (10) can transmit may be set to 23 dBm. The maximum transmit power may refer to the maximum power that the electronic device (10) can actually transmit in a specific situation in order to transmit an optimal signal. For example, the maximum transmit power may be a value obtained by applying an MPR to the maximum transmit power limit (MTPL). For example, the third maximum transmit power may be a value obtained by applying one value (e.g., an MPR value) selected from the third maximum power reduction values ​​(or an MPR table mapped in SISO operation) to the maximum transmit power limit (MTPL).

[0151] In operation 1320, the electronic device (10) may determine a first maximum transmission power by applying one of the first maximum power reduction values. In FIG. 13, the term "first maximum power reduction values" may be referred to as a term meaning a table in which MPR values ​​applicable when uplink signals are transmitted using a plurality of transmission antennas and the shape of the housing is the first shape are defined. In FIG. 13, the term "third maximum power reduction value" may be referred to as a term meaning one MPR value selected from among the first maximum power reduction values. In one example, the first maximum power reduction values ​​may be stored in the memory (270). For example, the memory (270) may store a table (e.g., first maximum power reduction values) in which MPR values ​​applicable to power class 2 (PC2) are defined according to a modulation scheme and a resource block (RB) when uplink signals are transmitted using a plurality of transmission antennas and the shape of the housing is the first shape.

[0152] In FIG. 13, the term "first maximum transmit power" may be referred to as a term meaning the maximum transmit power that can be applied when uplink signals are transmitted using a plurality of transmit antennas and the housing has the first shape. For example, the first maximum transmit power may be a value obtained by applying one value (e.g., the third maximum power reduction value) selected from the first maximum power reduction values ​​(or, an MPR table mapped to the first shape when multiple transmit antennas are operated) to the maximum transmit power limit (MTPL). The maximum transmit power and the maximum transmit power limit (MTPL) may be referred to as distinct terms.

[0153] The table below illustrates examples of MPR values ​​(e.g., first maximum power reduction values) that are applied when an electronic device (10) transmits uplink signals using multiple transmission antennas in a first configuration (e.g., unfolded configuration).

[0155] When the shape of the housing changes, the electronic device (10) may apply different MPR sizes depending on the shape of the housing. For example, when the electronic device (10) is in the first shape, the first maximum power reduction values ​​(e.g., Table 1) applied may be defined to have a smaller value than the second maximum power reduction values ​​(e.g., Table 2) applied when the electronic device (10) is in the second shape. When the shape of the housing is in the first shape, the electronic device (10) may be set to apply a smaller MPR than when the shape is in the second shape in determining the first maximum transmission power. In operation 1325, the electronic device (10) may determine the second maximum transmission power by applying one of the second maximum power reduction values. In FIG. 13, "second maximum power reduction values" may be referred to as a term referring to a table in which MPR values ​​applied when transmitting uplink signals using a plurality of transmission antennas and the shape of the housing is in the second shape are defined. In FIG. 13, the "fourth maximum power reduction value" may be referred to as a term meaning one MPR value selected from among the second maximum power reduction values. In one example, the second maximum power reduction values ​​may be stored in the memory (270). For example, the memory (270) may store a table (e.g., second maximum power reduction values) defining MPR values ​​applicable to power class 2 (PC2) when uplink signals are transmitted using a plurality of transmission antennas and the housing has the second shape according to a modulation scheme and a resource block (RB). In FIG. 13, the "second maximum transmission power" may be referred to as a term meaning the maximum transmission power applicable when uplink signals are transmitted using a plurality of transmission antennas and the housing has the second shape.For example, the second maximum transmit power may be a value obtained by applying a value (e.g., the fourth maximum power reduction value) selected from the second maximum power reduction values ​​(or the MPR table mapped to the second form when multiple transmit antennas are in operation) to the maximum transmit power limit (MTPL).

[0156] The table below illustrates examples of MPR values ​​(e.g., second maximum power reduction values) applicable when an electronic device (10) transmits uplink signals using multiple transmit antennas in a second form (e.g., folded form).

[0158] As described above with reference to FIGS. 4A to 10, the electronic device (10) may apply a different MPR size depending on the shape of the housing when the shape of the housing is changed. When the electronic device (10) transmits uplink signals using two or more antennas among a plurality of antennas, the separation distance between the antennas transmitting the uplink signals may change as the shape of the housing is changed. When the separation distance is changed, the isolation between the antennas transmitting the uplink signals may vary. In operation 1330, the electronic device (10) may control the transmission power for uplink signal transmission based on the maximum transmission power. The term "maximum transmission power" may be referred to as a term meaning a first maximum transmission power when uplink signals are transmitted using a plurality of transmission antennas and the shape of the housing is a first shape, a second maximum transmission power when uplink signals are transmitted using a plurality of transmission antennas and the shape of the housing is a second shape, and a third maximum transmission power when uplink signals are transmitted in an SISO manner.

[0159] Although not illustrated in FIG. 13, in one example, the electronic device (10) may further perform additional operations in determining the maximum transmit power associated with the transmit power for transmitting uplink signals. For example, the electronic device (10) may compare the maximum transmit power determined in operation 1315, operation 1320, or operation 1325 with a maximum value of the transmit power limited by a specific absorption rate (SAR), and control the transmit power for transmitting the uplink signal or uplink signals based on the smaller value of the two.

[0160] Although the embodiments described in this disclosure describe transmitting two uplink signals (e.g., 2Tx (transmission)), this is exemplary and not limiting. For example, the electronic device (10) may transmit four uplink signals (e.g., 4Tx), and in this case, the electronic device (10) may store MPR tables defining a greater number of different MPR values ​​than those described in this disclosure.

[0161] The embodiments described in FIG. 13 are exemplary and the embodiments of the present disclosure are not limited thereto. In one example, the electronic device (10) may include four transmit antennas. The electronic device (10) may select two of the four transmit antennas to transmit uplink signals. In this case, the memory (270) of the electronic device (10) may store a greater number of different maximum power reduction values ​​(or MPR table) that define MPR values, taking into account not only the shape of the housing but also the combination of antennas. For example, if the possible antenna combinations include a first antenna combination and / or a second antenna combination, the electronic device (10) may store maximum power reduction values ​​(or MPR table) when the first type is the first antenna combination, maximum power reduction values ​​(or MPR table) when the first type is the second antenna combination, maximum power reduction values ​​(or MPR table) when the second type is the first antenna combination, and maximum power reduction values ​​(or MPR table) when the second type is the second antenna combination.

[0162] The table below shows an example of isolation values ​​that vary depending on the combination of antennas used for transmitting uplink signals when the housing is in the first configuration (e.g., unfolded configuration).

[0163] Multiple Tx antenna system isolation table for Open state 2nd antenna 3rd antenna 4th antenna 1st antenna 15dB 5dB 10dB 2nd antenna 10dB 5dB 3rd antenna 7dB

[0164] The table below shows an example of isolation values ​​that vary depending on the combination of antennas used for transmitting uplink signals when the housing has a second configuration (e.g., a folding configuration).

[0165] Multiple Tx antenna system isolation table for Close state 2nd antenna 3rd antenna 4th antenna 1st antenna 10dB 5dB 5dB 2nd antenna 5dB 5dB 3rd antenna 5dB

[0166] In one example, the electronic device (10) may determine the maximum transmission power for uplink signal transmission by considering both the shape of the housing and the combination of antennas used for transmitting uplink signals. For example, the electronic device (10) may identify an isolation value according to the shape of the housing and the combination of antennas used for transmitting uplink signals, and may determine the maximum transmission power for uplink signal transmission according to the identified isolation value. For example, even if uplink signals are transmitted using the same antenna combination (e.g., first antenna and second antenna), the isolation value in the first form (e.g., 15 dB) and the isolation value in the second form (e.g., 10 dB) may be different. Even if the electronic device (10) transmits uplink signals using the same antenna combination, the maximum transmission power in the first form and the maximum transmission power in the second form may be determined as different values. For example, when the electronic device (10) is a second type and has a first antenna combination (e.g., a first antenna and a second antenna), the electronic device (10) can determine the maximum transmission power by referring to maximum power reduction values ​​(or an MPR table) that are different from the maximum power reduction values ​​(or an MPR table) that are referenced for determining the maximum transmission power when the electronic device (10) is a first type and has a first antenna combination.

[0167] Although the housing shape in FIG. 13 is described as including a first shape and a second shape, this is exemplary and embodiments of the present disclosure are not limited thereto. For example, the housing shape may include a third shape (e.g., a semi-folded shape) that is an intermediate shape between the first shape (e.g., an unfolded shape) and the second shape (e.g., a folded shape).

[0168] The table below shows an example of isolation values ​​that vary depending on the combination of antennas used for transmitting uplink signals when the housing has a third configuration (e.g., a semi-folding configuration).

[0169] Multiple Tx antenna system isolation table for intermediate state 2nd antenna 3rd antenna 4th antenna 1st antenna 12dB 5dB 7dB 2nd antenna 10dB 5dB 3rd antenna 5dB

[0170] In one example, even if the electronic device (10) transmits uplink signals using the same antenna combination (e.g., the first antenna and the second antenna), the isolation value (e.g., 12 dB) in the third form may be different from the isolation value (e.g., 15 dB) in the first form and the isolation value (e.g., 10 dB) in the second form. In one example, when it is the first form and the first antenna combination (e.g., the first antenna and the second antenna), the maximum power reduction values ​​(or MPR table) referenced for determining the maximum transmission power, when it is the second form and the first antenna combination, the maximum power reduction values ​​(or MPR table) referenced for determining the maximum transmission power, and when it is the third form and the first antenna combination, the maximum power reduction values ​​(or MPR table) referenced for determining the maximum transmission power may all be different.

[0171] FIG. 14 is a flowchart of a method for applying different maximum transmission power adjustment values ​​depending on the shape of a housing according to one embodiment.

[0172] The operations described below with reference to FIG. 14 may be referred to as operations of the electronic device (10) of FIG. 1. The order of the operations described below with reference to FIG. 14 is merely an example, and embodiments of the present disclosure are not limited thereto. For example, at least some of the operations may be executed differently from the order of FIG. 14, or may be executed substantially simultaneously with other operations of FIG. 14. At least some of the operations described below with reference to FIG. 14 may be omitted.

[0173] Referring to FIGS. 2 and 14, in operation 1405, the electronic device (10) may determine whether to transmit uplink signals using multiple transmission antennas. Referring to FIG. 13, the operation of determining that the electronic device (10) transmits uplink signals using multiple transmission antennas in operation 1405 may be referred to as described above in operation 1305.

[0174] If the electronic device (10) determines that it transmits uplink signals using multiple transmit antennas (e.g., operation 1405-YES), the electronic device (10) may perform operation 1410. If the electronic device (10) determines that it does not transmit uplink signals using multiple transmit antennas (e.g., operation 1405-NO), the electronic device may perform operation 1415.

[0175] In operation 1410, the electronic device (10) can determine (e.g., identify) the shape of the housing using the sensor (230). With respect to the first shape (e.g., unfolded shape) and the second shape (e.g., folded shape), reference may be made to the contents described above in FIGS. 4A to 4C, FIGS. 7A and 7B. Referring to FIG. 13, the operation of the electronic device (10) determining the shape of the housing in operation 1410 may be referenced to the contents described above in operation 1310.

[0176] If the electronic device (10) determines that the shape of the housing is the first shape (e.g., operation 1410 - first shape), the electronic device (10) can perform operation 1420. If the electronic device (10) determines that the shape of the housing is the second shape (e.g., operation 1410 - second shape), the electronic device can perform operation 1425.

[0177] In operation 1415, the electronic device (10) may determine a third maximum transmission power by applying a third adjustment value. Unlike the case where uplink signals are transmitted using multiple transmission antennas, when transmitting an uplink signal in the SISO manner, since there is only one transmission antenna, even if the shape of the housing changes, there may be no need to set the maximum transmission power differently depending on the housing shape. When transmitting an uplink signal in the SISO manner, the electronic device (10) may apply the same maximum transmission power without identifying the shape of the housing. In FIG. 14, the "third adjustment value" may be referred to as a term meaning an adjustment value applied to apply a maximum power reduction value (MPR) specified in a maximum transmission power limit (MTPL) when transmitting an uplink signal in the SISO manner and additionally adjust the transmission power. For example, the third adjustment value may have a specified value. As described above with respect to FIG. 13, the maximum power reduction value may include one of the maximum power reduction values ​​(or MPR table) stored in the memory (270), and may include one value referenced from the designated table. In one example, the third adjustment value may include a maximum transmit power adjustment value that is applied equally to all modulation schemes and resource blocks, regardless of the modulation scheme and resource block. In FIG. 14, the “third maximum transmit power” may be referred to as a term including one value (e.g., an MPR value) referenced from the maximum power reduction values ​​(e.g., a designated MPR table) specified in the maximum transmit power limit (MTPL) and a value that can be obtained by applying the third adjustment value. With respect to the maximum transmit power and the maximum transmit power limit, reference may be made to the contents described above with respect to FIG. 13. An operation of the electronic device (10) applying the third adjustment value to determine the third maximum transmit power may correspond to operation 1710 with reference to FIG. 17, which will be described later.

[0178] In operation 1420, the electronic device (10) may determine a first maximum transmission power by applying a first adjustment value. In FIG. 14, the term "first adjustment value" may be referred to as an adjustment value applied to transmit uplink signals using a plurality of transmission antennas, and to further adjust the transmission power by applying a maximum power reduction value (MPR) specified in the maximum transmission power limit (MTPL) when the housing has a first shape. For example, the first adjustment value may have a specified value (e.g., 2 dB). For example, the first adjustment value may be a positive value. In one example, the first adjustment value may include a maximum transmission power adjustment value that is applied equally to all modulation schemes and resource blocks, regardless of the modulation scheme and resource block. In FIG. 14, the term "first maximum transmit power" may be referred to as a term including a value (e.g., an MPR value) referenced from maximum power reduction values ​​(e.g., a designated MPR table) specified in the maximum transmit power limit (MTPL) and a value obtainable by applying the first adjustment value. In operation 1425, the electronic device (10) may determine the second maximum transmit power by applying the second adjustment value. In FIG. 14, the term "second adjustment value" may be referred to as a term meaning an adjustment value applied to transmit uplink signals using a plurality of transmit antennas, and to further adjust the transmit power by applying the maximum power reduction value (MPR) specified in the maximum transmit power limit (MTPL) when the housing has the second shape. For example, the second adjustment value may have a designated value (e.g., 0 dB). For example, the second adjustment value may be a negative value. In one example, the second adjustment value may include a maximum transmit power adjustment value that is applied equally to all modulation schemes and resource blocks, regardless of the modulation scheme and resource block.In FIG. 14, the term "second maximum transmit power" may be referred to as a term that includes a value (e.g., an MPR value) referenced from the maximum power reduction values ​​specified in the Maximum Transmit Power Limit (MTPL) (e.g., a specified MPR table) and a value that can be obtained by applying a second adjustment value.

[0179] The operation of determining the first maximum transmission power by applying the first adjustment value (e.g., operation 1420) and the operation of determining the second maximum transmission power by applying the second adjustment value (e.g., operation 1425) of the electronic device (10) may correspond to operation 1715 with reference to FIG. 17, which will be described later. For example, with reference to FIGS. 6 and 8, if the isolation between the plurality of transmission antennas changes according to a change in the shape of the housing, the electronic device (10a and / or 10b) may determine the maximum transmission power according to operation 1420 and / or operation 1425. For another example, with reference to FIG. 10, if the isolation between the plurality of transmission antennas does not change according to a change in the shape of the housing, the electronic device (10c) may determine the maximum transmission power according to operation 1715.

[0180] In operation 1430, the electronic device (10) can control the transmission power for uplink signal transmission based on the maximum transmission power. Referring to FIG. 13, the operation of controlling the transmission power for uplink signal transmission based on the maximum transmission power by the electronic device (10) in operation 1430 can be referred to as the content described above in operation 1330.

[0181] Although not illustrated in FIG. 14, in one example, the electronic device (10) may further perform additional operations in determining the maximum transmit power associated with the transmit power for transmitting uplink signals. For example, the electronic device (10) may compare the maximum transmit power determined in operation 1415, operation 1420, or operation 1425 with a maximum value of the transmit power limited by a specific absorption rate (SAR), and control the transmit power for transmitting the uplink signal or uplink signals based on the smaller value of the two.

[0182] The embodiments described in FIG. 14 are exemplary and the embodiments of the present disclosure are not limited thereto. In one example, the electronic device (10) may include four transmit antennas. The electronic device (10) may select two of the four transmit antennas to transmit uplink signals, and in this case, the memory (270) of the electronic device (10) may store a greater number of maximum transmit power adjustment values ​​by considering not only the shape of the housing but also the combination of antennas. For example, if the possible antenna combinations include the first antenna combination and / or the second antenna combination, the electronic device (10) may store the maximum transmit power adjustment value in the case of the first type and the first antenna combination, the maximum transmit power adjustment value in the case of the first type and the second antenna combination, the maximum transmit power adjustment value in the case of the second type and the first antenna combination, and the maximum transmit power adjustment value in the case of the second type and the second antenna combination. The isolation values ​​according to the shape of the housing and the combination of antennas used for transmitting uplink signals can be referenced with the same contents as Tables 3 and 4 described above in FIG. 13.

[0183] Although the housing shape in FIG. 14 is described as including a first shape and a second shape, this is exemplary and embodiments of the present disclosure are not limited thereto. For example, the housing shape may include a third shape (e.g., a semi-folded shape) that is an intermediate shape between the first shape (e.g., an unfolded shape) and the second shape (e.g., a folded shape). When the housing shape is the third shape (e.g., a semi-folded shape), isolation values ​​according to the combination of antennas used for transmitting uplink signals may be referenced with the same contents as Table 5 described above in FIG. 13.

[0184] FIG. 15 is a flowchart of a method for applying different MPR values ​​according to an antenna combination according to one embodiment.

[0185] The operations described below with reference to FIG. 15 may be referred to as the operations of the electronic device (10) of FIG. 1. The order of the operations described below with reference to FIG. 15 is merely an example, and embodiments of the present disclosure are not limited thereto. For example, at least some of the operations may be executed differently from the order of FIG. 15, or may be executed substantially simultaneously with other operations of FIG. 15. At least some of the operations described below with reference to FIG. 15 may be omitted.

[0186] Referring to FIGS. 2, 3, 11, and 15, in operation 1505, the electronic device (10) may control a switch circuit to select a plurality of transmission antennas to be used for transmitting uplink signals among a plurality of antennas (210). For example, the electronic device (10) may control each of a plurality of transmission paths (e.g., a first transmission path (300) and / or a second transmission path (not shown)) to be connected to two or more antennas among a first antenna (351), a second antenna (352), and / or a third antenna (353) through a switch circuit (330). For example, the electronic device (10) may select a plurality of transmission antennas to be used for transmitting uplink signals through switch circuits (e.g., the switch circuit (330) of FIG. 3 and / or the switch circuits (1131, 1132) of FIG. 11). For example, the electronic device (10) may select a plurality of transmission antennas to be used for transmitting uplink signals through the switch circuits (1131, 1132) by considering the signal characteristics (e.g., frequency and / or signal strength) of each antenna according to the current communication environment. In operation 1510, the electronic device (10) may determine (e.g., identify) whether an antenna combination is an antenna combination that is set to be unusable. In one example, the memory (270) of the electronic device (10) may store isolation values ​​for each combination of antennas used for transmitting uplink signals. The table below illustrates an example of isolation values ​​that differ for each combination of antennas used for transmitting uplink signals.

[0187] 2nd antenna 3rd antenna 4th antenna 1st antenna 15dB 5dB 10dB 2nd antenna 10dB 5dB 3rd antenna 7dB

[0188] In one example, the electronic device (10) may be configured to not transmit uplink signals using antennas having an isolation lower than a specified value. For example, if the electronic device (10) is configured to not transmit uplink signals when the isolation value between antennas is less than 10 dB, then, referring to Table 6, the electronic device (10) may be configured to not transmit uplink signals using the first antenna and the third antenna combination (5 dB), the third antenna and the fourth antenna combination (7 dB), and the second antenna and the fourth antenna combination (5 dB). In one example, the electronic device (10) may store information on antenna combinations that can be used for transmitting uplink signals (e.g., antenna combinations having an isolation equal to or greater than a specified value) and / or information on antenna combinations that cannot be used for transmitting uplink signals (e.g., antenna combinations having an isolation less than a specified value) with reference to the isolation between antennas. The electronic device (10) may determine whether an antenna combination is an unusable combination using the stored information.

[0189] If the electronic device (10) determines that the antenna combination is not set to be used (e.g., operation 1510-YES), the electronic device (10) may perform operation 1505 again. In this case, the electronic device (10) may reselect a new antenna combination for transmitting uplink signals. If the electronic device (10) determines that the antenna combination is not set to be used (e.g., operation 1510-NO), the electronic device may perform operation 1515.

[0190] In operation 1515, the electronic device (10) can determine (e.g., identify) which combination of antennas is used to transmit uplink signals. For example, the electronic device (10) can select two antennas to be used to transmit uplink signals among four antennas (e.g., a first antenna, a second antenna, a third antenna, and a fourth antenna) through a switch circuit, and the combination of antennas can vary depending on which antennas are selected. For example, when uplink signals are transmitted using the first antenna and the second antenna, the electronic device (10) can identify the first antenna combination. For example, when uplink signals are transmitted using the first antenna and the fourth antenna, the electronic device (10) can identify the second antenna combination.

[0191] Although only the first antenna combination and the second antenna combination are described for convenience of explanation in operation 1515, the embodiments of the present disclosure are not limited thereto. For example, the number of antenna combinations that can be used for transmitting uplink signals is not limited to two. The number of antenna combinations that can be used for transmitting uplink signals may exceed two. For example, if the total number of antennas and the number of antennas selected for transmitting uplink signals increase, the number of possible antenna combinations may also increase.

[0192] If the electronic device (10) identifies the first antenna combination (e.g., operation 1515 - first antenna combination), the electronic device (10) may perform operation 1520. If the electronic device (10) identifies the second antenna combination (e.g., operation 1515 - second antenna combination), the electronic device may perform operation 1525.

[0193] In operation 1520, the electronic device (10) may determine the first maximum transmission power by applying one of the first maximum power reduction values. In FIG. 15, the term "first maximum power reduction values" may be referred to as a table defining MPR values ​​applicable when the combination of antennas used for transmitting uplink signals is the first antenna combination. In FIG. 15, the term "third maximum power reduction value" may be referred to as a term indicating one MPR value selected from among the first maximum power reduction values. In one example, the first maximum power reduction values ​​may be stored in the memory (270). For example, the memory (270) may store a table (e.g., the first maximum power reduction values) defining MPR values ​​applicable to power class 2 (PC2) according to a modulation scheme and a resource block (RB) when the combination of antennas used for transmitting uplink signals is the first antenna combination. In FIG. 15, the term "first maximum transmit power" may be referred to as a term meaning the maximum transmit power that can be applied when the combination of antennas used for transmitting uplink signals is the first antenna combination. For example, the first maximum transmit power may be a value obtained by applying one value (e.g., the third maximum power reduction value) selected from the first maximum power reduction values ​​(or, in the case of multiple transmit antenna operation, an MPR table mapped to the first antenna combination) to the maximum transmit power limit (MTPL). The maximum transmit power and the maximum transmit power limit (MTPL) may be referred to as distinct terms. With respect to the maximum transmit power and the maximum transmit power limit, reference may be made to the contents described above in FIG. 13.

[0194] The table below shows examples of MPR values ​​(e.g., first maximum power reduction values) applied when the electronic device (10) transmits uplink signals with the first antenna combination.

[0196] The electronic device (10) may apply different MPR sizes depending on the combination of antennas used for transmitting uplink signals. For example, when the combination of antennas used for transmitting uplink signals is the first antenna combination, the first maximum power reduction values ​​(e.g., Table 7) applied may be defined to have smaller values ​​than the second maximum power reduction values ​​(e.g., Table 8) applied when the combination of antennas used for transmitting uplink signals is the second antenna combination. When the combination of antennas used for transmitting uplink signals is the first antenna combination, the electronic device (10) may be configured to apply a smaller MPR than when the combination of antennas used for transmitting uplink signals is the second antenna combination in determining the first maximum transmission power.

[0197] In operation 1525, the electronic device (10) may determine the second maximum transmission power by applying one of the second maximum power reduction values. In FIG. 15, the term "second maximum power reduction values" may be referred to as a table defining MPR values ​​applicable when the combination of antennas used for transmitting uplink signals is the second antenna combination. In FIG. 15, the term "fourth maximum power reduction value" may be referred to as a term indicating one MPR value selected from among the second maximum power reduction values. In one example, the second maximum power reduction values ​​may be stored in the memory (270). For example, the memory (270) may store a table (e.g., the second maximum power reduction values) defining MPR values ​​applicable to power class 2 (PC2) according to a modulation scheme and a resource block (RB) when the combination of antennas used for transmitting uplink signals is the second antenna combination. In FIG. 15, the term "second maximum transmit power" may be referred to as a term meaning the maximum transmit power that can be applied when the combination of antennas used for transmitting uplink signals is the second antenna combination. For example, the second maximum transmit power may be a value obtained by applying one value (e.g., the fourth maximum power reduction value) selected from the second maximum power reduction values ​​(or, in the case of multiple transmit antenna operation, an MPR table mapped to the second antenna combination) to the maximum transmit power limit (MTPL). The maximum transmit power and the maximum transmit power limit (MTPL) may be referred to as distinct terms. With respect to the maximum transmit power and the maximum transmit power limit, reference may be made to the contents described above in FIG. 13.

[0198] The table below illustrates examples of MPR values ​​(e.g., second maximum power reduction values) that are applied when the electronic device (10) transmits uplink signals with a second antenna combination.

[0200] The electronic device (10) may apply different MPR sizes depending on the combination of antennas used for transmitting uplink signals. For example, when the combination of antennas used for transmitting uplink signals is the second antenna combination, the second maximum power reduction values ​​(e.g., Table 8) applied may be defined to have a larger value than the first maximum power reduction values ​​(e.g., Table 7) applied when the combination of antennas used for transmitting uplink signals is the first antenna combination. When the combination of antennas used for transmitting uplink signals is the second antenna combination, the electronic device (10) may be configured to apply a larger MPR than when the combination of antennas used for transmitting uplink signals is the first antenna combination in determining the second maximum transmission power.

[0201] In operation 1525, for convenience of explanation, only the first antenna combination and the second antenna combination are described, but the embodiments of the present disclosure are not limited thereto. For example, when transmitting uplink signals using the second antenna and the third antenna, the electronic device (10) can identify the third antenna combination. The electronic device (10) can be configured to refer to the same maximum power reduction values ​​(or MPR table) for antenna combinations having the same isolation value (e.g., the second antenna combination (10 dB) and the third antenna combination (10 dB)).

[0202] In operation 1530, the electronic device (10) may control the transmission power for uplink signal transmission based on the maximum transmission power. The term "maximum transmission power" may be referred to as a term that means the first maximum transmission power when the combination of antennas used for transmitting uplink signals is the first antenna combination, and means the second maximum transmission power when the combination of antennas used for transmitting uplink signals is the second antenna combination.

[0203] Although not illustrated in FIG. 15, in one example, the electronic device (10) may further perform additional operations in determining the maximum transmit power associated with the transmit power for transmitting uplink signals. For example, the electronic device (10) may compare the maximum transmit power determined in operation 1520 or operation 1525 with the maximum value of the transmit power limited by the specific absorption rate (SAR), and control the transmit power for transmitting the uplink signal or uplink signals based on the smaller value of the two.

[0204] Although the present disclosure describes an embodiment in which two out of four antennas are selected to transmit uplink signals, this is exemplary and not limiting. For example, the electronic device (10) may select two or more antennas out of four or more multiple antennas to transmit uplink signals, and in this case, the electronic device (10) may store MPR tables defining a greater number of different MPR values ​​than those described in the present disclosure.

[0205] FIG. 16 is a flowchart of a method for applying different maximum transmission power adjustment values ​​according to an antenna combination according to one embodiment.

[0206] The operations described below with reference to FIG. 16 may be referred to as operations of the electronic device (10) of FIG. 1. The order of the operations described below with reference to FIG. 16 is merely an example, and embodiments of the present disclosure are not limited thereto. For example, at least some of the operations may be executed differently from the order of FIG. 16, or may be executed substantially simultaneously with other operations of FIG. 16. At least some of the operations described below with reference to FIG. 16 may be omitted.

[0207] Referring to FIGS. 2, 3, 11, 15, and 16, in operation 1605, the electronic device (10) may control a switch circuit to select a plurality of transmission antennas to be used for transmitting uplink signals among a plurality of antennas (210). For example, the electronic device (10) may control each of a plurality of transmission paths (e.g., a first transmission path (300) and / or a second transmission path (not shown)) to be connected to two or more antennas among a first antenna (351), a second antenna (352), and / or a third antenna (353) through a switch circuit (330). For example, the electronic device (10) may select a plurality of transmission antennas to be used for transmitting uplink signals through switch circuits (e.g., a switch circuit (330) of FIG. 3 and / or switch circuits (1131, 1132) of FIG. 11). Referring to FIG. 15, the operation of controlling the switch circuit by the electronic device (10) in operation 1605 to select a plurality of transmission antennas to be used for transmitting uplink signals among the plurality of antennas (210) may be referred to as the content described above in operation 1505.

[0208] In operation 1610, the electronic device (10) may determine (e.g., identify) whether the antenna combination is an antenna combination that is set to be unusable. Referring to FIG. 15, the operation of the electronic device (10) in operation 1610 for determining whether the antenna combination is an antenna combination that is set to be unusable may be referred to as described above in operation 1510.

[0209] If the electronic device (10) determines that the antenna combination is disabled (e.g., operation 1610-YES), the electronic device (10) may perform operation 1605 again. If the electronic device (10) determines that the antenna combination is not disabled (e.g., operation 1610-NO), the electronic device may perform operation 1615.

[0210] In operation 1615, the electronic device (10) may determine (e.g., identify) which combination of antennas is used to transmit uplink signals. Referring to FIG. 15, the operation of identifying which combination of antennas is used to transmit uplink signals by the electronic device (10) in operation 1615 may be referred to as described above in operation 1515.

[0211] In operation 1615, only the first antenna combination and the second antenna combination are described for convenience of explanation, but embodiments of the present disclosure are not limited thereto. For example, the number of antenna combinations that can be used for transmitting uplink signals is not limited to two. The number of antenna combinations that can be used for transmitting uplink signals may exceed two. For example, if the total number of antennas and the number of antennas selected for transmitting uplink signals increase, the number of possible antenna combinations may also increase.

[0212] If the electronic device (10) identifies the first antenna combination (e.g., operation 1615 - first antenna combination), the electronic device (10) may perform operation 1620. If the electronic device (10) identifies the second antenna combination (e.g., operation 1615 - second antenna combination), the electronic device may perform operation 1625.

[0213] In operation 1620, the electronic device (10) may determine a first maximum transmission power by applying a first adjustment value. In FIG. 16, the term "first adjustment value" may be referred to as an adjustment value applied to further adjust the transmission power by applying a maximum power reduction value (MPR) specified in a maximum transmission power limit (MTPL) when a combination of antennas used for transmitting uplink signals is the first antenna combination. For example, the first adjustment value may have a specified value (e.g., 2 dB). For example, the first adjustment value may be a positive value. In one example, the specified maximum power reduction value (MPR) may include one of the maximum power reduction values ​​(or MPR table) stored in the memory (270) and may include one value referenced in the specified table. In one example, the first adjustment value may include a maximum transmission power adjustment value that is applied equally to all modulation schemes and resource blocks, regardless of distinction according to the modulation scheme and resource block. In FIG. 16, the term "first maximum transmit power" may be referred to as a term including a value (e.g., an MPR value) referenced from the maximum power reduction values ​​specified in the maximum transmit power limit (MTPL) (e.g., a specified MPR table) and a value obtainable by applying the first adjustment value. The maximum transmit power and the maximum transmit power limit (MTPL) may be referred to as distinct terms. With respect to the maximum transmit power and the maximum transmit power limit, reference may be made to the content described above in FIG. 13.

[0214] In operation 1625, the electronic device (10) may determine a second maximum transmission power by applying a second adjustment value. In FIG. 16, the term "second adjustment value" may be referred to as an adjustment value applied to further adjust the transmission power by applying a maximum power reduction value (MPR) specified in a maximum transmission power limit (MTPL) when a combination of antennas used for transmitting uplink signals is a second antenna combination. For example, the second adjustment value may have a specified value (e.g., 0 dB). For example, the second adjustment value may be a negative value. In one example, the specified maximum power reduction value (MPR) may include one of the maximum power reduction values ​​(or MPR table) stored in the memory (270) and may include one value referenced in the specified table. In one example, the second adjustment value may include a maximum transmission power adjustment value that is applied equally to all modulation schemes and resource blocks, regardless of distinction according to the modulation scheme and resource block. In FIG. 16, the term "second maximum transmit power" may be referred to as a term including a value (e.g., an MPR value) referenced from the maximum power reduction values ​​specified in the maximum transmit power limit (MTPL) (e.g., a specified MPR table) and a value that can be obtained by applying a second adjustment value. The maximum transmit power and the maximum transmit power limit (MTPL) may be referred to as distinct terms. With respect to the maximum transmit power and the maximum transmit power limit, reference may be made to the content described above in FIG. 13.

[0215] In operation 1525, only the first antenna combination and the second antenna combination are described for convenience of explanation, but embodiments of the present disclosure are not limited thereto. For example, when transmitting uplink signals using the second antenna and the third antenna, the electronic device (10) can identify the third antenna combination. For antenna combinations having the same isolation value (e.g., the second antenna combination (10 dB) and the third antenna combination (10 dB)), the electronic device (10) can determine the maximum transmission power by applying the same adjustment value (e.g., the second adjustment value).

[0216] In operation 1630, the electronic device (10) can control the transmission power for uplink signal transmission based on the maximum transmission power. Referring to FIG. 13, the operation of controlling the transmission power for uplink signal transmission based on the maximum transmission power by the electronic device (10) in operation 1630 can be referred to as the content described above in operation 1330.

[0217] Although not illustrated in FIG. 16, in one example, the electronic device (10) may further perform additional operations in determining the maximum transmit power associated with the transmit power for transmitting uplink signals. For example, the electronic device (10) may compare the maximum transmit power determined in operation 1620 or operation 1625 with the maximum value of the transmit power limited by the specific absorption rate (SAR), and control the transmit power for transmitting the uplink signal or uplink signals based on the smaller value of the two.

[0218] FIG. 17 is a flowchart of a method for setting maximum transmission power in uplink transmission according to one embodiment.

[0219] The operations described below with reference to FIG. 17 may be referred to as operations of the electronic device (10) of FIG. 1. The order of the operations described below with reference to FIG. 17 is merely an example, and embodiments of the present disclosure are not limited thereto. For example, at least some of the operations may be executed differently from the order of FIG. 17, or may be executed substantially simultaneously with other operations of FIG. 17. At least some of the operations described below with reference to FIG. 17 may be omitted.

[0220] Referring to FIGS. 2 and 17, in operation 1705, the electronic device (10) may determine whether to transmit uplink signals using multiple transmit antennas. For example, the electronic device (10) may determine to transmit uplink signals using multiple transmit antennas when at least two antennas are used, depending on the number of antennas used for uplink signal transmission. For example, the electronic device (10) may determine to transmit uplink signals in a SISO manner when one antenna is used, depending on the number of antennas used for uplink signal transmission.

[0221] If the electronic device (10) determines that it transmits uplink signals using multiple transmit antennas (e.g., operation 1705-YES), it may perform operation 1715. If the electronic device (10) determines that it does not transmit uplink signals using multiple transmit antennas (e.g., operation 1705-NO), it may perform operation 1710.

[0222] In operation 1710, the electronic device (10) may determine a maximum transmission power applicable when uplink signals are not transmitted using a plurality of transmission antennas. When uplink signals are not transmitted using a plurality of transmission antennas, this may mean, for example, when uplink signals are transmitted using a SISO method. Referring to FIGS. 13 and 14, the maximum transmission power applicable when uplink signals are not transmitted using a plurality of transmission antennas may include a third maximum transmission power.

[0223] The table below illustrates examples of maximum transmit power limits (MTPL) and tolerances (e.g., tolerances) applicable to different power classes and frequency bands. The electronic device (10) can store the applicable maximum transmit power values ​​for different power classes and frequency bands in the memory (270).

[0224] NR bandClass 1.5(dBm)Tolerance(dB)Class 2(dBm)Tolerance(dB)Class 3(dBm)Tolerance(dB)n3023±2n3426+2 / -323±2n3823±2n3926+2 / -323±2 n4026+2 / -323±2n4129+2 / -326+2 / -323±2n4723±2n4823+2 / -3n5023±2n51 23±2n5323±2n6523±2n6623±2n7023±2n7123+2 / -2.5n7423±2n7729+2 / -3 26+2 / -323+2 / -3n7829+2 / -326+2 / -323+2 / -3n7929+2 / -326+2 / -323+2 / -3

[0225] The electronic device (10) may determine the maximum transmission power for transmitting an uplink signal in the SISO manner. For example, referring to Table 9, the electronic device (10) may determine the maximum transmission power for transmitting an uplink signal in the SISO manner in power class 2 (PC2) of the n41 frequency band to be 26 dBm. In one example, "maximum transmission power limits" may be referred to as a term referring to a table (e.g., Table 9) that stores maximum transmission power limits (MTPLs) that may be applied according to power classes and frequency bands.

[0226] In operation 1715, the electronic device (10) may set the maximum transmission power to be higher by a specified value within the tolerance range in the case of a multiple transmit antenna operation. In one example, the electronic device (10) may be configured to apply different maximum transmission powers when transmitting signals in the SISO manner and when transmitting signals in the multiple transmit antenna operation within the same power class. For example, the electronic device (10) may be configured to apply a higher maximum transmission power when transmitting signals in the multiple transmit antenna operation than when transmitting signals in the SISO manner. For example, the electronic device (10) may apply a higher maximum transmission power value than the maximum transmission power applied to signal transmission in the SISO manner when the isolation between the plurality of antennas used to transmit signals in the multiple transmit antenna operation is equal to or higher than a specified value and hardware performances (e.g., adjacent channel leakage ratio (ACLR), error vector magnitude (EVM)) satisfy specified conditions. For example, when transmitting signals with multiple transmit antenna operation, the electronic device (10) may apply a higher maximum transmit power value within the tolerance range. For example, referring to Table 9, the maximum transmit power limit value may be set to 26 dBm in power class 2 of the n41 frequency band. Referring to Table 9, in the case of signal transmission with the SISO method, the electronic device (10) may determine the maximum transmit power to be 26 dBm, which is the same as the maximum transmit power limit value. Referring to Table 9, when transmitting signals with multiple transmit antenna operation, the electronic device (10) may set the maximum transmit power limit value of 26 dBm to a value of 23 dBm or more and 28 dBm or less, including the tolerance range.For example, referring to Table 9, the maximum transmission power of a signal transmission in the SISO mode in power class 2 of the n41 frequency band is set to 26 dBm, and the maximum transmission power of a multiple transmission antenna operation mode in power class 2 of the n41 frequency band can be set to a value higher than 26 dBm by a specified value (e.g., +1 dB) within the tolerance range.

[0227] In operation 1720, the electronic device (10) can control the transmission power for uplink signal transmission based on the maximum transmission power. Referring to FIG. 13, the operation of controlling the transmission power for uplink signal transmission based on the maximum transmission power by the electronic device (10) in operation 1720 can be referred to as the content described above in operation 1330.

[0228] Although not illustrated in FIG. 17, in one example, the electronic device (10) may perform additional operations in determining the maximum transmit power associated with the transmit power for transmitting uplink signals. For example, the electronic device (10) may compare the maximum transmit power determined in operation 1710 or operation 1715 with the maximum value of the transmit power limited by the specific absorption rate (SAR), and control the transmit power for transmitting uplink signals based on the smaller value of the two.

[0229] The embodiments described in FIG. 17 are exemplary and the embodiments of the present disclosure are not limited thereto. In one example, the electronic device (10) may include four transmit antennas. The electronic device (10) may select two of the four transmit antennas to transmit uplink signals, and in this case, the memory (270) of the electronic device (10) may store isolation values ​​between the antennas transmitting the uplink signals for each combination of antennas transmitting the uplink signals. If the isolation between the transmit antennas is excessively small, the quality of the transmitted signal may be significantly degraded. In one example, the electronic device (10) may be configured so that antennas having an isolation between transmit antennas stored in the memory (270) below a specified value cannot be used for uplink signal transmission. In one example, the electronic device (10) may store information on antenna combinations that can transmit in a multiple transmit antenna operation manner and / or information on antenna combinations that cannot transmit in a multiple transmit antenna operation manner. The electronic device (10) can use the stored information to determine whether the antenna combination corresponds to an unusable combination. In one example, even if the electronic device (10) transmits uplink signals using a plurality of transmission antennas, the electronic device (10) can check the isolation value between the transmission antennas stored in the memory (270) and, only if the isolation value is higher than a specified value, set the maximum transmission power to a value higher by a specified value within a tolerance.

[0230] In one example, the electronic device (10) may determine whether to set the maximum transmission power higher by a specified value within a tolerance, taking into account not only the combination of transmitting antennas transmitting uplink signals but also other factors affecting the isolation size (e.g., a change in the shape of the housing). The memory (270) of the electronic device (10) may store isolation values ​​between antennas transmitting uplink signals according to the shape of the housing and the combination of antennas transmitting uplink signals. For example, if the possible antenna combinations include a first antenna combination and / or a second antenna combination, and the possible housing shape includes the first shape and / or the second shape, the electronic device (10) may store an isolation value when the first shape is the first antenna combination, an isolation value when the first shape is the second antenna combination, an isolation value when the second shape is the first antenna combination, and an isolation value when the second shape is the second antenna combination.

[0231] Figure 18 is a flowchart of a method for readjusting maximum transmission power when there is a change in housing shape during uplink signal transmission.

[0232] The operations described below with reference to FIG. 18 may be referred to as operations of the electronic device (10) of FIG. 1. The order of the operations described below with reference to FIG. 18 is merely an example, and embodiments of the present disclosure are not limited thereto. For example, at least some of the operations may be executed differently from the order of FIG. 18, or may be executed substantially simultaneously with other operations of FIG. 18. At least some of the operations described below with reference to FIG. 18 may be omitted.

[0233] Referring to FIGS. 2, 13, 14, 15, 16, and 18, in operation 1805, the electronic device (10) can transmit uplink signals by controlling the uplink signal transmission power to the maximum transmission power determined according to the antenna combination. The operation of controlling the uplink signal transmission power to the maximum transmission power determined according to the antenna combination may be referred to as described above in operation 1330 of FIG. 13, operation 1430 of FIG. 14, operation 1530 of FIG. 15, and / or operation 1630 of FIG. 16.

[0234] In operation 1810, the electronic device (10) may detect a change in the shape of the housing when the shape of the housing changes while transmitting uplink signals. For example, the electronic device (10) may detect a change in the shape of the housing using the sensor (230). The operation of the electronic device (10) detecting a change in the shape of the housing using the sensor (230) may be referred to as described above in FIG. 2.

[0235] In operation 1815, the electronic device (10) may determine whether the positions of the transmitting antennas have changed due to a change in the shape of the housing. For example, referring to FIG. 6, if there is a change in the shape of the housing (410, 420) (e.g., a change from S1 to S2), the positions of the antennas transmitting the uplink signals may change. For example, referring to FIGS. 7A and 8, if there is a change in the shape of the housing (710, 720) (e.g., a change from S1 to S2), the positions of the antennas transmitting the uplink signals may change. For example, referring to FIG. 10, despite a change in the shape of the housing (1010, 1020), the positions of the antennas transmitting the uplink signals may not change.

[0236] If the electronic device (10) determines that the positions of the transmitting antennas have changed due to a change in the shape of the housing (e.g., operation 1815-YES), the electronic device (10) may perform operation 1820. If the electronic device (10) determines that the positions of the transmitting antennas have not changed due to a change in the shape of the housing (e.g., operation 1815-NO), the electronic device (10) may terminate the maximum transmit power readjustment without performing any additional operations.

[0237] In operation 1820, the electronic device (10) may determine whether the antenna combination whose position has been changed is an antenna combination that has been set to be unusable. Referring to FIGS. 15 and 16, the operation of determining whether an antenna combination is set to be unusable may be referred to as described above in operation 1510 and / or operation 1610.

[0238] If the electronic device (10) determines that the antenna combination whose position has been changed is an antenna combination that is set to be unusable (e.g., operation 1820-YES), the electronic device (10) may perform operation 1825. In operation 1825, the electronic device (10) may control a switch circuit (e.g., the switch circuit (330) of FIG. 3 and / or the switch circuits (1131, 1132) of FIG. 11) to reselect a plurality of transmit antennas to be used for transmitting uplink signals. The operation of reselecting a plurality of transmit antennas may be referred to as described above in operations 1310 to 1325 of FIG. 13, operations 1410 to 1425 of FIG. 14, operation 1505 of FIG. 15, and / or operation 1605 of FIG. 16. If the electronic device (10) determines that the changed antenna combination is not an antenna combination that is set to be unusable (e.g., operation 1820-NO), the electronic device (10) may perform operation 1830.

[0239] In operation 1830, the electronic device (10) may adjust the maximum transmit power associated with the transmit power control for transmitting uplink signals based on the changed antenna combination. The electronic device (10) may be configured to identify a different antenna combination when the isolation between the transmit antennas changes due to a change in the shape of the housing, even if the transmit antennas do not change. For example, referring to FIG. 13, the electronic device (10) may store isolation values ​​(e.g., Table 3, Table 4, and / or Table 5) in a memory by considering both the shape of the housing and the antenna combination, and may identify an antenna combination whose isolation changes due to a change in the shape of the housing as a different antenna combination by referring to the stored isolation values, even when the same transmit antenna is used.

[0240] Referring to FIGS. 13 to 16, the operation of newly determining the maximum transmission power associated with the transmission power control for transmitting uplink signals based on the antenna combination whose position has changed in the electronic device (10) may be referred to as the operation of FIG. 13 (e.g., operation 1315, operation 1320, and / or operation 1325), the operation of FIG. 14 (e.g., operation 1415, operation 1420, and / or operation 1425), the operation of FIG. 15 (e.g., operation 1520, and / or operation 1525), and / or the operation of FIG. 16 (e.g., operation 1520, and / or operation 1525), which are described above in FIGS. 13 to 16.

[0241] In operation 1835, the electronic device (10) may control the uplink signal transmission power based on the maximum transmission power adjusted in operation 1830. The operation of controlling the uplink signal transmission power with the adjusted maximum transmission power may be referred to as described above in operation 1330 of FIG. 13, operation 1430 of FIG. 14, operation 1530 of FIG. 15, and / or operation 1630 of FIG. 16.

[0242] FIG. 19 is a block diagram of an exemplary electronic device (1900) capable of performing the operations described in this document.
