For example, to identify the location of the external electronic device, the electronic device may identify the angle of arrival (AoA) of a signal received through the antennas. The electronic device may identify the direction and / or distance of the external electronic device relative to the electronic device based on the phase difference between the antennas, the distance between the antennas, and the AoA. The electronic device may identify the location of the external electronic device based on the direction and / or distance.

The electronic device may include at least one processor including processing circuitry. The electronic device may include a memory including one or more storage media storing instructions. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to identify a first channel associated with an ultra-wideband (UWB) signal to be received from a first external electronic device. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to move the second housing part relative to the first housing part, via the driving unit, to adjust a distance between the first antenna and the second antenna to a first distance corresponding to the first channel, in order to receive a UWB signal using the first channel. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to identify a second channel associated with a UWB signal to be received from a second external electronic device.The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to control the driving unit to move the second housing part relative to the first housing part so as to adjust the distance between the first antenna and the second antenna to a second distance corresponding to the second channel.

[0006] A method is provided, performed by an electronic device, comprising a first housing part and a second housing part movably coupled with respect to the first housing part. The method may include identifying a first channel associated with an ultra-wideband (UWB) signal to be received from a first external electronic device. The method may include moving the second housing part relative to the first housing part so as to adjust a distance between a first antenna disposed on the first housing part and a second antenna disposed on the second housing part to a first distance corresponding to the first channel. The method may include identifying a second channel associated with a UWB signal to be received from a second external electronic device. The method may include moving the second housing part relative to the first housing part so as to adjust the distance between the first antenna and the second antenna to a second distance corresponding to the second channel. The distance between the first antenna and the second antenna may be changeable based on a position of the second housing part relative to the first housing part.

[0032] FIG. 1 is a block diagram of an electronic device within a network environment, according to one embodiment.

[0033] Referring to FIG. 1, in a network environment (100), an electronic device (101) may communicate with an electronic device (102) via a first network (198) (e.g., a short-range wireless communication network), or may communicate with an electronic device (104) or a server (108) via a second network (199) (e.g., a long-range wireless communication network). In one embodiment, the electronic device (101) may communicate with the electronic device (104) via the server (108). According to one embodiment, the electronic device (101) may include a processor (120), a memory (130), an input module (150), an audio output module (155), a display module (160), an audio module (170), a sensor module (176), an interface (177), a connection terminal (178), a haptic module (179), a camera module (180), a power management module (188), a battery (189), a communication module (190), a subscriber identification module (196), or an antenna module (197). In some embodiments, the electronic device (101) may omit at least one of these components (e.g., the connection terminal (178)), or may have one or more other components added. In some embodiments, some of these components (e.g., the sensor module (176), the camera module (180), or the antenna module (197)) may be integrated into one component (e.g., the display module (160)).

[0034] The processor (120) may, for example, execute software (e.g., a program (140)) to control at least one other component (e.g., a hardware or software component) of the electronic device (101) connected to the processor (120) and perform various data processing or operations. According to one embodiment, as at least a part of the data processing or operations, the processor (120) may store commands or data received from other components (e.g., a sensor module (176) or a communication module (190)) in a volatile memory (132), process the commands or data stored in the volatile memory (132), and store result data in a non-volatile memory (134). According to one embodiment, the processor (120) may include a main processor (121) (e.g., a central processing unit or an application processor) or an auxiliary processor (123) (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or together with the main processor (121). For example, when the electronic device (101) includes the main processor (121) and the auxiliary processor (123), the auxiliary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a given function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0035] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, in the electronic device (101) itself where artificial intelligence is performed, or can be performed through a separate server (e.g., server (108)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above. The artificial intelligence model can include multiple artificial neural network layers.The artificial neural network may be one of a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-network, or a combination of two or more of the above, but is not limited to the examples described above. In addition to, or alternatively to, a hardware structure, an artificial intelligence model may include a software structure.

[0036] The memory (130) can store various data used by at least one component (e.g., processor (120) or sensor module (176)) of the electronic device (101). The data can include, for example, software (e.g., program (140)) and input data or output data for commands related thereto. The memory (130) can include volatile memory (132) or non-volatile memory (134).

[0037] The program (140) may be stored as software in the memory (130) and may include, for example, an operating system (142), middleware (144), or an application (146).

[0038] The input module (150) can receive commands or data to be used in a component of the electronic device (101) (e.g., a processor (120)) from an external source (e.g., a user) of the electronic device (101). The input module (150) can include, for example, a microphone, a mouse, a keyboard, a key (e.g., a button), or a digital pen (e.g., a stylus pen).

[0039] The audio output module (155) can output audio signals to the outside of the electronic device (101). The audio output module (155) can include, for example, a speaker or a receiver. The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0040] The display module (160) can visually provide information to an external party (e.g., a user) of the electronic device (101). The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0041] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), output sound through the sound output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0042] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0043] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) to an external electronic device (e.g., the electronic device (102)). In one embodiment, the interface (177) may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0044] The connection terminal (178) may include a connector through which the electronic device (101) may be physically connected to an external electronic device (e.g., electronic device (102)). According to one embodiment, the connection terminal (178) may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0045] The haptic module (179) can convert electrical signals into mechanical stimuli (e.g., vibration or movement) or electrical stimuli that a user can perceive through tactile or kinesthetic sensations. According to one embodiment, the haptic module (179) can include, for example, a motor, a piezoelectric element, or an electrical stimulation device.

[0046] The camera module (180) can capture still images and videos. According to one embodiment, the camera module (180) may include one or more lenses, image sensors, image signal processors, or flashes.

[0047] The power management module (188) can manage the power supplied to the electronic device (101). According to one embodiment, the power management module (188) can be implemented as, for example, at least a part of a power management integrated circuit (PMIC).

[0048] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0049] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0050] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0051] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas by, for example, the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0052] In one embodiment, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0053] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0054] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0055] For example, the display of the display module (160) may be flexible. For example, the display may include a display area that is exposed outside the housing of the electronic device (101), which provides at least a portion of the outer surface of the electronic device (101). For example, since the display has flexibility, at least a portion of the display may be rollable into the housing or slidable into the housing. For example, the size of the display area may change depending on the size of the at least a portion of the display that is rolled into the housing or slid into the housing. For example, the electronic device (101) including the display may be in a plurality of states, including a first state providing the display area having a first size and a second state providing the display area having a second size different from the first size. For example, the first state may be exemplified through the description of FIGS. 2A and 2B.

[0056] FIG. 2A is a top plan view of an exemplary electronic device in a first state.

[0057] Referring to FIG. 2A, the electronic device (101) may include a housing (201) and a flexible display (230). For example, the housing (201) may include a first housing part (210) and a second housing part (220). For example, the second housing part (220) may be movable relative to the first housing part (210) in a first direction (261) parallel to the y-axis or in a second direction (262) parallel to the y-axis and opposite to the first direction (261). Although the second housing part (220) is described as being movable relative to the first housing part (220) within the present disclosure, it is not limited thereto. For example, the housing (201) may have a structure in which the overall size of the housing (201) may change according to a change in the relative positional relationship between the first housing part (210) and the second housing part (220). For example, the relative positional relationship between the first housing part (210) and the second housing part (220) may be changed by the operation of the motor (361) described later. For example, the first housing part (210) may be movable with respect to the second housing part (220), or both the first housing part (210) and the second housing part (220) may be movable by the motor (361).

[0058] For example, the electronic device (101) may be in the first state. For example, within the first state, the second housing part (220) may be movable relative to the first housing part (210) in a first direction (261) among the first direction (261) and the second direction (262). For example, within the first state, the second housing part (220) may not be substantially movable relative to the first housing part (210) in the second direction (262).

[0059] For example, within the first state, the flexible display (230) can provide the display area having the smallest size. For example, within the first state, the display area can correspond to the first display area (230a). For example, although not shown in FIG. 2A, within the first state, a second display area (e.g., the second display area (230b) of FIG. 2C) of the flexible display (230) that is different from the first display area (230a) can be included within the first housing part (210). For example, within the first state, the area (e.g., the second display area (230b) of FIG. 2C) can be covered by the first housing part (210). For example, within the first state, the area can be rolled into the first housing part (210). For example, within the first state, the first display area (230a) may include a planar portion. However, this is not limited thereto. For example, the first display area (230a) may also include a curved portion extending from the planar portion and positioned within an edge portion within the first state.

[0060] For example, the first state may be referred to as a slide-in state or a closed state in that at least a portion of the second housing part (220) is positioned within the first housing part (210). For example, the first state may be referred to as a reduced state in that it provides the display area having the smallest size, but is not limited thereto.

[0061] For example, the second housing part (220) may include a first image sensor (250-1) within the camera module (180) that is exposed through a portion of the first display area (230a) and faces a third direction (263) parallel to the z-axis. For example, although not illustrated in FIG. 2A, the second housing part (220) may include one or more second image sensors within the camera module (180) that are exposed through a portion of the second housing part (220) and faces a fourth direction (264) parallel to the z-axis and opposite to the third direction (263). For example, the one or more second image sensors may be exemplified through the description of FIG. 2B.

[0062] FIG. 2b is a bottom view of an exemplary electronic device in a first state.

[0063] Referring to FIG. 2B, within the first state, one or more second image sensors (250-2) disposed within the second housing part (220) may be positioned within a structure disposed within the first housing part (210) for the one or more second image sensors (250-2). For example, light from outside the electronic device (101) may be received by the one or more second image sensors (250-2) through the structure within the first state. For example, since the one or more second image sensors (250-2) are positioned within the structure within the first state, the one or more second image sensors (250-2) may be exposed through the structure within the first state. For example, the structure may be implemented in various ways. For example, the structure may be an opening or a notch. For example, the structure may be an opening (212a) in the first plate (212) of the first housing part (210) that surrounds at least a portion of the second housing part (220). However, the present invention is not limited thereto. For example, in the first state, one or more second image sensors (250-2) included in the second housing part (220) may be covered by the first plate (212) of the first housing part (210).

[0064] For example, the first state can be changed to the second state.

[0065] For example, the first state (or the second state) can be changed to the second state (or the first state) through intermediate states between the first state and the second state.

[0066] For example, the first state (or the second state) may be changed to the second state (or the first state) based on a user input. For example, the first state (or the second state) may be changed to the second state (or the first state) in response to a user input to a physical button exposed through a part of the first housing part (210) or a part of the second housing part (220). For example, the first state (or the second state) may be changed to the second state (or the first state) in response to a touch input to an executable object displayed within the display area. For example, the first state (or the second state) may be changed to the second state (or the first state) in response to a touch input having a contact point on the display area and having a pressing strength greater than or equal to a reference strength. For example, the first state (or the second state) may be changed to the second state (or the first state) in response to a voice input received through a microphone of the electronic device (101). For example, the first state (or the second state) may be changed to the second state (or the first state) in response to an external force applied to the first housing part (210) and / or the second housing part (220) to move the second housing part (220) with respect to the first housing part (210). For example, the first state (or the second state) may be changed to the second state (or the first state) in response to a user input identified from an external electronic device (e.g., earbuds or a smart watch) connected to the electronic device (101). However, the present invention is not limited thereto.

[0067] The second state can be illustrated through the description of FIGS. 2c and 2d.

[0068] Figure 2c is a plan view of an exemplary electronic device in a second state.

[0069] Referring to FIG. 2C, the electronic device (101) may be in the second state. For example, in the second state, the second housing part (220) may be movable relative to the first housing part (210) in the second direction (262) among the first direction (261) and the second direction (262). For example, in the second state, the second housing part (220) may not be substantially movable relative to the first housing part (210) in the first direction (261).

[0070] For example, within the second state, the flexible display (230) may provide the display area having the largest size. For example, within the second state, the display area may correspond to an area (230c) including a first display area (230a) and a second display area (230b). For example, the second display area (230b), which was included within the first housing part (210) within the first state, may be exposed within the second state. For example, within the second state, the first display area (230a) may include a flat portion. However, the present invention is not limited thereto. For example, the first display area (230a) may also include a curved portion extending from the flat portion and positioned within the edge portion. For example, within the second state, the second display area (230b) may, unlike the first display area (230a) within the first state, include a flat portion among the flat portion and the curved portion. However, this is not limited thereto. For example, the second display area (230b) may also include a curved portion that extends from the flat portion of the second display area (230b) and is positioned within the edge portion.

[0071] For example, the second state may be referred to as a slide-out state or an open state in that at least a portion of the second housing part (220) disposed outside the first housing part (210) extends relative to the first state. For example, the second state may be referred to as an expanded state in that it provides the display area having the largest size. However, the present invention is not limited thereto.

[0072] For example, the first image sensor (250-1) facing the third direction (263) may move together with the first display area (230a) according to the movement of the second housing part (220) in the first direction (261) when the state of the electronic device (101) changes from the first state to the second state. For example, although not shown in FIG. 2c, one or more second image sensors (250-2) facing the fourth direction (264) may move according to the movement of the second housing part (220) in the first direction (261) when the state of the electronic device (101) changes from the first state to the second state. For example, the relative positional relationship between one or more second image sensors (250-2) and the structure illustrated through the description of FIG. 2d may change according to the movement of one or more second image sensors (250-2). For example, the change in the above relative position relationship can be illustrated through Fig. 2d.

[0073] FIG. 2d is a bottom view of an exemplary electronic device in a second state.

[0074] Referring to FIG. 2d, within the second state, one or more second image sensors (250-2) may be positioned outside the structure. For example, the structure may include an opening (212a). For example, within the second state, one or more second image sensors (250-2) may be positioned outside the opening (212a) in the first plate (212). For example, one or more second image sensors (250-2) may be exposed through the opening (212a) within the first state. For example, because one or more second image sensors (250-2) are positioned outside the first housing part (210) within the second state, one or more second image sensors (250-2) may be exposed within the second state. For example, since one or more second image sensors (250-2) are positioned outside the structure within the second state, the relative positional relationship within the second state may be different from the relative positional relationship within the first state.

[0075] For example, if the electronic device (101) does not include the above structure such as the opening (212a), one or more second image sensors (250-2) may be exposed within the second state among the first state and the second state.

[0076] Although not shown in FIGS. 2A, 2B, 2C, and 2D, the electronic device (101) may be in an intermediate state between the first state and the second state. For example, the size of the display area in the intermediate state may be larger than the size of the display area in the first state and smaller than the size of the display area in the second state. For example, the display area in the intermediate state may correspond to an area including a portion of the first display area (230a) and the second display area (230b). For example, in the intermediate state, a portion of the second display area (230b) may be exposed, and another portion (or a remaining portion) of the second display area (230b) may be covered by the first housing part (210) or rolled into the first housing part (210). However, the present invention is not limited thereto.

[0077] Referring again to FIG. 1, the electronic device (101) may include structures for moving a second housing (e.g., a second housing part (220) of FIG. 2A) of the electronic device (101) relative to a first housing (e.g., a first housing part (210) of FIG. 2A) of the electronic device (101). For example, the structures may be exemplified through the description of FIGS. 3A and 3B.

[0078] Figures 3a and 3b are exploded perspective views of an exemplary electronic device.

[0079] Referring to FIGS. 3A and 3B, the electronic device (101) may include a first housing part (210), a second housing part (220), a flexible display (230), and a driving unit (360).

[0080] For example, the first housing part (210) may include a first cover (311), a first plate (212), and a frame (313).

[0081] For example, the first cover (311) may at least partially form a side portion of an outer surface of the electronic device (101). For example, the first cover (311) may include an opening (311a) for one or more second image sensors (250-2). For example, the first cover (311) may include a surface that supports the first plate (212). For example, the first cover (311) may be coupled with the first plate (212). For example, the first cover (311) may include a frame (313). For example, the first cover (311) may be coupled with the frame (313).

[0082] For example, the first plate (212) may at least partially form a rear portion of the outer surface. For example, the first plate (212) may include an opening (212a) for one or more second image sensors (250-2). For example, the first plate (212) may be disposed on the surface of the first cover (311). For example, the opening (212a) may be aligned with the opening (311a).

[0083] For example, the frame (313) may be at least partially surrounded by the first cover (311).

[0084] For example, the frame (313) can be at least partially wrapped by the flexible display (230). For example, although the frame (313) is at least partially wrapped by the flexible display (230), the position of the frame (313) can be maintained independently of the movement of the flexible display (230). For example, the frame (313) can be arranged with respect to at least some of the components of the flexible display (230). For example, the frame (313) can include rails (313a) that provide (or guide) a path of movement of at least one component of the flexible display (230).

[0085] For example, the frame (313) can be coupled with at least one component of the electronic device (101). For example, the frame (313) can support the battery (189). For example, the frame (313) can be coupled with one end of a flexible printed circuit board (FPCB) (325) on a surface of the frame (313). For example, although not explicitly shown in FIGS. 3A and 3B , the other end of the FPCB (325) can be connected to the PCB (324) via at least one connector. For example, the PCB (324) can be electrically connected to another PCB (not shown in FIGS. 3A and 3B ) that supplies power to the motor (361) via the FPCB (325).

[0086] For example, the frame (313) can be combined with at least one structure of the electronic device (101) for a plurality of states including the first state and the second state. For example, the frame (313) can fasten the motor (361) of the driving unit (360).

[0087] For example, the second housing part (220) may include a second cover (321) and a second plate (322).

[0088] For example, the second cover (321) may be at least partially wrapped by the flexible display (230). For example, the second cover (321) may be combined with at least a portion of the first display area (230a) of the flexible display (230) wrapping the second cover (321).

[0089] For example, the second cover (321) may be coupled with at least one component of the electronic device (101). For example, the second cover (321) may be coupled with a printed circuit board (PCB) (324) including components of the electronic device (101). For example, the PCB (324) may include at least one processor (e.g., the processor (120) of FIG. 1) (not shown in FIGS. 3A and 3B). For example, the second cover (321) may support one or more second image sensors (250-2).

[0090] For example, the second cover (321) can be combined with the second plate (322).

[0091] For example, the second plate (322) may be coupled with the second cover (321) to protect at least one component of the electronic device (101) coupled within the second cover (321) and / or at least one structure of the electronic device (101) coupled within the second cover (321). For example, the second plate (322) may include a structure for the at least one component. For example, the second plate (322) may include one or more openings (326) for one or more second image sensors (250-2). For example, the one or more openings (326) may be aligned with one or more second image sensors (250-2) disposed on the second cover (321). For example, the size of each of the one or more openings (326) may correspond to the size of each of the lenses included in the one or more second image sensors (250-2).

[0092] For example, the electronic device (101) may include a support member (331) for supporting at least a portion of the flexible display (230). For example, the support member (331) may include a plurality of bars. For example, the plurality of bars may be coupled to each other. The support member (331) may support a second display area (230b) of the flexible display (230).

[0093] For example, the driving unit (360) may include a motor (361), a pinion gear (362), and a rack gear (363).

[0094] For example, the motor (361) may operate based on power from the battery (189). For example, the power may be provided to the motor (361) in response to the user input.

[0095] For example, the pinion gear (362) may be coupled to the motor (361) via a shaft. For example, the pinion gear (362) may be rotated based on the motion of the motor (361) transmitted via the shaft.

[0096] For example, the rack gear (363) can be arranged in relation to the pinion gear (362). For example, teeth of the rack gear (363) can mesh with teeth of the pinion gear (362). For example, the rack gear (363) can be moved in the first direction (261) or the second direction (262) according to the rotation of the pinion gear (362). For example, the rack gear (363) can be coupled with the first housing part (210) or the second housing part (220). For example, the second housing part (220) can be moved in the first direction (261) and the second direction (262) by the rack gear (363) that is moved according to the rotation of the pinion gear (362) due to the operation of the motor (361). For example, the first state of the electronic device (101) can be changed to a state different from the first state (e.g., one or more intermediate states or the second state) through the movement of the second housing part (220) in the first direction (261). For example, the second state of the electronic device (101) can be changed to a state different from the second state (e.g., one or more intermediate states or the first state) through the movement of the second housing part (220) in the second direction (262). For example, the first state being changed to the second state by the driving unit (360) and the second state being changed to the first state by the driving unit (360) can be exemplified through FIGS. 4A and 4B.

[0097] Fig. 4a is a cross-sectional view of an exemplary electronic device in a first state. Fig. 4b is a cross-sectional view of an exemplary electronic device in a second state.

[0098] For example, FIG. 4A is a cross-sectional view of an exemplary electronic device (101) taken along line A-A' of FIG. 2A. For example, FIG. 4B is a cross-sectional view of an exemplary electronic device (101) taken along line B-B' of FIG. 2C.

[0099] Referring to FIGS. 4A and 4B, the motor (361) can be operated based at least in part on the defined user input received within the first state (490). For example, the pinion gear (362) can be rotated in the first rotational direction (411) based at least in part on the operation of the motor (361). For example, the rack gear (363) can be moved in the first direction (261) based at least in part on the rotation of the pinion gear (362) in the first rotational direction (411). For example, the second housing part (220) can be moved in the first direction (261) based at least in part on the movement of the rack gear (363) in the first direction (261). For example, the second cover (321) within the second housing part (220) can be moved based at least in part on the movement of the rack gear (363) in the first direction (261). For example, the flexible display (230) can be moved along the rails (313a). For example, the shape of at least a portion of the plurality of bars of the support member (331) of the flexible display (230) can be changed when the state (490) is changed to the state (495) which is the second state.

[0100] For example, the second display area (230b) of the flexible display (230) may be moved according to the movement of the flexible display (230). For example, the second display area (230b) may be moved through the space between the first cover (311) and the frame (313) when the state (490) is changed to the state (495) according to the user input defined above. For example, the second display area (230b) in the state (495) may be exposed, unlike the second display area (230b) that is rolled into the space in the state (490).

[0101] For example, since the second cover (321) within the second housing part (220) is coupled with the PCB (324) connected to the other end of the FPCB (325) and fixes the rack gear (363), the shape of the FPCB (325) can be changed when the state (490) is changed to the state (495).

[0102] The motor (361) can be operated based at least in part on the defined user input received within the state (495). For example, the pinion gear (362) can be rotated in the second rotational direction (412) based at least in part on the operation of the motor (361). For example, the rack gear (363) can be moved in the second direction (262) based at least in part on the rotation of the pinion gear (362) in the second rotational direction (412). For example, the second housing part (220) can be moved in the second direction (262) based at least in part on the movement of the rack gear (363) in the second direction (262). For example, the flexible display (230) can be moved based at least in part on the movement of the rack gear (363) in the second direction (262). For example, the flexible display (230) can be moved along the rails (313a). For example, the shape of at least a portion of the plurality of bars of the support member (331) of the flexible display (230) can be changed when the state (495) is changed to the state (490). The support member (331) can be moved with respect to the first housing part (210). In the state (490), the support member (331) housed inside the first housing part (210) can be positioned between the first cover (311) and the frame (313). As the support member (331) moves, the flexible display (230) can be moved with respect to the first housing part (210).

[0103] For example, the second display area (230b) of the flexible display (230) can be moved according to the movement of the flexible display (230). For example, the second display area (230b) can be moved through the space between the first cover (311) and the frame (313) when the state (495) is changed to the state (490) according to the user input defined above. For example, the second display area (230b) in the state (490) can be rolled into the space, unlike the second display area (230b) exposed in the state (495).

[0104] For example, since the second cover (321) of the second housing part (220) is coupled with the PCB (324) connected to the other end of the FPCB (325) and fixes the rack gear (363), the shape of the FPCB (325) can be changed when the state (495) is changed to the state (490).

[0105] Hereinafter, an electronic device (101) and a method for identifying the location of an external electronic device (e.g., the external electronic device (501) of FIG. 5A) based on wireless signals in a wireless communication system (e.g., an LTE communication system, an NR communication system) are described. Specifically, the electronic device (101) can identify an angle of arrival (AoA) of a signal received from the external electronic device (501) using a plurality of antennas (e.g., the first antenna (510), the second antenna (520), and / or the third antenna (530) of FIG. 5A). The electronic device (101) can be configured to identify the location of the external electronic device (501) based on the AoA.

[0106] The electronic device (101) can identify the location of an external electronic device (501) using an ultra-wideband (UWB) signal. UWB refers to a communication bandwidth having a bandwidth of 500 MHz or more and a fractional bandwidth of 20% or more. Since the resolution of the radar that can be identified through the UWB signal is high, the direction of the external electronic device (501) with respect to the electronic device (101) and the distance of the external electronic device (501) with respect to the electronic device (101) can be precisely identified. Based on the direction and distance, the location of the external electronic device (501) can be identified.

[0107] As described above, the electronic device (101) according to one embodiment can adjust the distance between the antennas that receive the signal for identifying the angle of arrival because the relative positional relationship between the first housing part (210) and the second housing part (220) can be adjusted. For example, the second housing part (220) can be slidably coupled to the first housing part (210). The electronic device (101) according to one embodiment can adjust the position of the second housing part (220) so as to precisely measure the angle of arrival.

[0108] The description, with reference to the attached drawings, is provided to facilitate a comprehensive understanding of the various embodiments of the present disclosure, as defined by the claims and their equivalents. While numerous specific details are included to facilitate understanding, they are to be considered merely exemplary. Those skilled in the art will recognize that various modifications and variations can be made to the various embodiments described herein without departing from the scope and spirit of the present disclosure. Descriptions of known functions and configurations may be omitted or simplified for clarity and conciseness.

[0109] FIG. 5A illustrates an environment in which an electronic device, according to one embodiment, performs an operation to identify the location of an external electronic device. FIG. 5B illustrates an example of a method for identifying the angle between an electronic device and an external electronic device using an angle of arrival. FIG. 5C illustrates an example of a method for identifying the distance between an electronic device and an external electronic device using an angle of arrival.

[0110] Referring to FIG. 5A, an electronic device (101) according to one embodiment may include antennas (510, 520, 530) capable of receiving signals from an external electronic device (501). For example, the electronic device (101) may include, but is not limited to, a first antenna (510), a second antenna (520), and / or a third antenna (530). For example, the third antenna (530) may be omitted. For example, the electronic device (101) may include four or more antennas to identify the location of the external electronic device (501).

[0111] According to one embodiment, the electronic device (101) may receive a signal using short-range communication (e.g., Bluetooth low energy (BLE)) with an external electronic device (501), but is not limited thereto. BLE communication can reduce battery power consumption by activating a connection when transmitting data and otherwise communicating based on a connectionless basis. Using BLE communication, the electronic device (101) may be paired with the external electronic device (501). The electronic device (101) may receive a signal from the external electronic device (501) through a specific channel among a plurality of UWB channels. The electronic device (101) may identify an angle of arrival and / or a distance between the external electronic device (501) and the electronic device (101) based on a signal received from the external electronic device (501). The electronic device (101) can identify the location of the external electronic device (501) based on the arrival angle and the distance.

[0112] According to one embodiment, the external electronic device (501) may include various electronic devices. For example, the external electronic device (501) may include, but is not limited to, a first external electronic device (501a) (e.g., a wearable device), a second external electronic device (501b) (e.g., a home appliance), and / or a third external electronic device (501c) (e.g., a control device of a vehicle). According to one embodiment, the external electronic device (501) may include a location tracking device for providing location information. For example, the external electronic device (501) may include, but is not limited to, an anchor device and / or a smart tag including an antenna (502) configured to transmit a signal.

[0113] An electronic device (101) according to one embodiment may receive a signal radiated from an antenna (502) of an external electronic device (501) via one or more antennas (510, 520, 530). In the present disclosure, a signal received via a first antenna (510) may be referred to as a first signal (S1), and a signal received via a second antenna (520) may be referred to as a second signal (S2). For convenience of explanation, the first signal (S1) and the second signal (S2) are distinguished based on the receiving antenna, with respect to the received signal radiated from the antenna (502) of the external electronic device (501). According to one embodiment, the electronic device (101) can identify the relative direction of the external electronic device (501) with respect to the electronic device (101) by identifying the angle of arrival based on the distance between the first antenna (510) and the second antenna (520), the phase difference between the signal received through the first antenna (510) and the signal received through the second antenna (520).

[0114] The method for identifying the angle of arrival illustrated in FIG. 5B is a PDoA (phase difference of Arrival) method. Referring to FIG. 5B, an electronic device (e.g., the electronic device (101) of FIG. 5A) can receive a signal radiated from an external electronic device (e.g., the external electronic device (501) of FIG. 5A) via a first antenna (510) and a second antenna (520). A first signal (S1) can be received via the first antenna (510), and a second signal (S2) can be received via the second antenna (520). The electronic device (101) can identify the phase of the first signal (S1) and the phase of the second signal (S2). The electronic device (101) can identify the phase difference between the phase of the first signal (S1) and the phase difference between the second signal (S2), and, based on the identified phase difference, identify the angle of arrival of the signal received from the external electronic device (501).

[0115] In a wireless communication system (e.g., LTE communication system, NR communication system) providing a mobile network, a far field can be defined. In the far field, an electromagnetic signal can be interpreted as a plane wave. The second antenna (520) can be spaced apart from the first antenna (510) by a specified distance (d). Based on the direction perpendicular to the plane on which the first antenna (510) and the second antenna (520) are arranged, the first signal (S1) and the second signal (S2) are each It can be incident on the first antenna (510) and the second antenna (520) at an angle. The angle may be referred to as the incident angle. The distance difference between the second signal (S2) received through the second antenna (520) and the first signal (S1) received through the first antenna (510) is dsin The phase of the first signal (S1) received through the first antenna (510) and the phase of the second signal (S2) received through the second antenna (520) may be different due to the difference in distance between the first signal (S1) and the second signal (S2). The electronic device (101) uses the distance between the first antenna (510) and the second antenna (520), the phase difference, and the wavelength of the signal. You can identify the angle. For example, The angle can be calculated using the following mathematical formula 1.

[0116]

[0117] The angle may be referred to as a relative angle between the electronic device (101) and the external electronic device (501), so that the electronic device (101) can identify the direction of the external electronic device (501) with respect to the electronic device (101).

[0118] The distance identification method illustrated in FIG. 5C is a two-way ranging (TWR) method. Referring to FIG. 5C, an electronic device (e.g., electronic device (101) of FIG. 5A) can transmit a signal to an external electronic device (e.g., external electronic device (501) of FIG. 5A). For example, the electronic device (101) can transmit a poll for distance measurement. The electronic device (101) can check information regarding the timing (T0) at which the signal was transmitted. The signal can be received by the external electronic device (501) at a timing (T1) after a time of flight (ToF) has elapsed from the timing (T0).

[0119] According to one embodiment, the external electronic device (501) can transmit a response signal to the signal to the electronic device (101). For example, the external electronic device (501) can transmit a response to the poll to the electronic device (101) at a timing (T2) after a response time has elapsed from the timing (T1) at which the signal is received.

[0120] According to one embodiment, the electronic device (101) can receive the response signal. The timing (T3) at which the electronic device (101) receives the response signal may be a timing (T3) at which a flight time has elapsed from the timing (T2) at which the external electronic device (501) transmits the response signal. The time interval from the timing (T0) at which the electronic device (101) transmits the signal to the timing (T3) at which the response signal is received may be referred to as the round trip time (RTT) of the RF signal between the electronic device (101) and the external electronic device (501). The distance (D) between the electronic device (101) and the external electronic device (501) can be calculated using the following mathematical expression 2.

[0121]

[0122] The speed of radio waves in the atmosphere is the speed of light (about 3×10 8 m / s), the electronic device (101) can identify the distance between the electronic device (101) and the external electronic device (501).

[0123] Referring back to FIG. 5A, according to one embodiment, the distance between the first antenna (510) and the second antenna (520) may be important in order to accurately identify the location of the external electronic device (501). For example, if the distance is too long, problems such as distortion of the phase of the first signal (S1) and the phase of the second signal (S2), deterioration of resolution, and increase in signal attenuation may occur. For example, if the distance is too short, problems such as increased interference between the first signal (S1) and the second signal (S2), increased influence of surrounding structures, and deterioration of phase linearity may occur. The above problems may reduce the accuracy of direction identification and distance identification of the external electronic device (501) with respect to the electronic device (101). In order to improve the accuracy of identifying the location of the external electronic device (501), it may be necessary to select an optimal distance between the first antenna (510) and the second antenna (520) by taking various factors into consideration. For example, the optimal distance may be determined based on the frequency band of the UBW channel used for communication with the external electronic device (501).

[0124] According to one embodiment, the optimal distance may substantially correspond to 1 / 2w, where w is the wavelength corresponding to the center frequency of the UWB channel established between the electronic device (101) and the external electronic device (501). For example, the optimal distance may be smaller than w / 2. However, the present invention is not limited thereto. In the present disclosure, the optimal distance is described as corresponding to w / 2, but this is only an example, and the optimal distance is not limited to corresponding to w / 2. For example, the optimal distance may be determined based on factors such as the structure of the electronic device (101), the communication environment, and the performance of the electronic device (101).

[0125] According to one embodiment, in the case of an electronic device having a bar-type structure, since the structure of the electronic device is fixed without being deformed, the distance between the first antenna and the second antenna can be fixed. As the distance is fixed, the electronic device cannot adjust the distance depending on the frequency band of the UWB channel, the channel supported by the external electronic device (501), or the communication environment. For example, even if the distance between the first antenna and the second antenna is not appropriate for using a specific UWB channel, communication performance may deteriorate because the distance cannot be adjusted.

[0126] As described above, the electronic device (101) according to one embodiment may include a housing (201) having a slider structure including a first housing part (210) and a second housing part (220). According to one embodiment, the first antenna (510) may be disposed on the first housing part (210), and the second antenna (520) may be disposed on the second housing part (220). As the second housing part (220) slides relative to the first housing part (210), the distance between the first antenna (510) and the second antenna (520) may change. For example, as the position of the second housing part (220) relative to the first housing part (210) changes, the distance between the first antenna (510) and the second antenna (520) may change. Within the present disclosure, the position of the second housing part (220) relative to the first housing part (210) may be referenced as a position value.

[0127] An electronic device (101) according to one embodiment may be configured to provide an optimal distance between a first antenna (510) and a second antenna (520) based on a frequency band of a UWB channel to identify an angle of arrival. The electronic device (101) may change the distance between the first antenna (510) and the second antenna (520) to the optimal distance by controlling a driving unit (e.g., the driving unit (360) of FIG. 6) to change the position of the second housing part (220) with respect to the first housing part (210) according to the UWB channel. The electronic device (101) may identify an angle of arrival of a signal radiated from an antenna (502) of an external electronic device (501) by using the first antenna (510) and the second antenna (520) spaced apart by the optimal distance. If the channel available to the external electronic device (501) includes multiple channels, the electronic device (101) can identify the quality of a signal received through each of the multiple channels. The electronic device (101) can determine a UWB channel to be used for communication with the external electronic device (501) based on the quality. The electronic device (101) can cause the second housing part (220) to move so that the distance between the first antenna (510) and the second antenna (520) corresponds to the distance between the first antenna (510) and the second antenna (520) corresponding to the determined UWB channel. The movement of the second housing part (220) can be performed by the control of a driving unit (e.g., a driving unit (360) of FIG. 6). According to one embodiment, as the accuracy of identifying the direction and / or distance of the external electronic device (501) to the electronic device (101) is improved, the accuracy of identifying the location of the external electronic device (501) may be improved.

[0128] FIG. 6 is a block diagram illustrating components of an electronic device according to one embodiment. FIG. 7A illustrates an electronic device according to one embodiment in a first state. FIG. 7B illustrates an electronic device according to one embodiment in a second state.

[0129] The components of the electronic device (101) illustrated in FIG. 6 are merely exemplary and are not limited thereto. In addition to the components illustrated in FIG. 6, the electronic device (101) may further include at least one of the components described with reference to FIGS. 1 to 4B. Descriptions that overlap with the above description may be omitted or briefly described, and components that are substantially the same as the components described above may be given the same reference numerals.

[0130] According to one embodiment, the electronic device (101) may include a housing (e.g., housing (201) of FIG. 5A), antennas (e.g., first antenna (510), second antenna (520), and / or third antenna (530)), a driving unit (360), a memory (130), and at least one processor (120).

[0131] According to one embodiment, the housing (201) may include a first housing part (e.g., the first housing part (210) of FIG. 5A) and a second housing part (e.g., the second housing part (220) of FIG. 5A). For example, the second housing part (220) may be slidably coupled to the first housing part (210). The position of the second housing part (220) relative to the first housing part (210) may be referenced as a position value.

[0132] Referring to FIG. 7A, an electronic device (101) in a first state is illustrated. The first state may be referred to as a state in which the second housing part (220) is maximally inserted into the first housing part (210). The first state may correspond to the first state described with reference to FIGS. 2A and 2B. Referring to FIG. 7B, an electronic device (101) in a second state is illustrated. The second state may be referred to as a state in which the second housing part (220) is maximally pulled out from the first housing part (210). The second state may correspond to the second state described with reference to FIGS. 2C and 2D.

[0133] According to one embodiment, the position value of the second housing part (220) may be 0 in the first state and may be maximum (about 40 mm) in the second state. For example, as illustrated in FIG. 7A, in the first state, the distance between the first antenna (510) and the second antenna (520) (e.g., distance (a) in FIG. 7A) may be minimum. For example, as illustrated in FIG. 7B, in the second state, the distance between the first antenna (510) and the second antenna (520) (e.g., distance (b) in FIG. 7B) may increase depending on the distance the second housing part (220) has moved. The distance between the first antenna (510) and the second antenna (520) may be changed within the range of a to b based on the position of the second housing part (220). For example, if the position value of the second housing part (220) is c, the distance between the first antenna (510) and the second antenna (520) can be referred to as a+c.

[0134] In the following description, the second housing part (220) is described as having a structure in which it is movably coupled to the first housing part (210), but is not limited thereto. According to various embodiments, the electronic device (101) may have a structure in which the relative positions between the first housing part (210) and the second housing part (220) are changed. For example, the electronic device (101) may include a structure in which the first housing part (210) moves with respect to the second housing part (220). In this case, the driving unit (360) may move the first housing part (210), and the distance between the first antenna (510) and the second antenna (520) may be adjusted by the sliding of the first housing part (210).

[0135] According to one embodiment, at least one processor (120) may be configured to control the operation of the electronic device (101). Any function or operation described in the present disclosure may be processed by one processor or a combination of processors. One processor or a combination of processors may include, as a circuit that performs processing, an application processor (AP, eg, a central processing unit (CPU)), a communication processor (CP, eg, a modem), a graphics processing unit (eg, a GPU), a neural processing unit (NPU) (eg, an artificial intelligence (AI) chip), a wireless-fidelity (Wi-Fi) chip, a Bluetooth™ chip, a global positioning system (GPS) chip, a near field communication (NFC) chip, connectivity chips, a sensor controller, a touch controller, a finger-print sensor controller, a display drive integrated circuit (DDI), an audio CODEC chip, a universal serial bus (USB) controller, a camera controller, an image processing IC, a microprocessor unit (MPU), a system on chip (SoC), an IC, or a similar circuit.

[0136] According to one embodiment, at least one processor (120) may be operatively connected to wireless communication circuitry (192). For example, the wireless communication circuitry (192) may include a UWB integrated circuit (IC) used to transmit and / or receive UWB signals. For example, the wireless communication circuitry (192) may include a radio frequency (RF) transceiver and a radio frequency front end (RFFE). The wireless communication circuitry (192) may be configured to convert a baseband signal generated by the at least one processor (120) into an RF signal (e.g., a UWB signal) and transmit the converted RF signal via the first antenna (510), the second antenna (520), and / or the third antenna (530). The wireless communication circuit (192) may be configured to convert an RF signal (e.g., a UWB signal) received through the first antenna (510), the second antenna (520), and / or the third antenna (530) into a baseband signal that may be processed by at least one processor (120), and provide the converted baseband signal to the at least one processor (120).

[0137] According to one embodiment, the driving unit (360) may be configured to provide a driving force to provide a first state, a second state, and an intermediate state between the first state and the second state of the electronic device (101). For example, the driving unit (360) may include a motor (e.g., motor (361) of FIG. 3A), a pinion gear (e.g., pinion gear (362) of FIG. 3A), and a rack gear (e.g., rack gear (363) of FIG. 3A). The motor (361) may operate based on power provided from a battery (e.g., battery (189) of FIG. 3A). The pinion gear (362) may be coupled to the motor (361) via a shaft. The pinion gear (362) may rotate based on the rotational motion of the motor (361) transmitted via the shaft. The rack gear (363) can be moved based on the rotation of the pinion gear (362) by meshing with the pinion gear (362). The motor (361) may also be referred to as an actuator in terms of operating as a device that provides movement of the second housing part (220).

[0138] In the embodiments of the present disclosure, the driving unit (360) is not limited to the examples described above. In the examples described above, the driving unit (360) is described as providing movement of the second housing part (220) through the operation of the pinion gear (362) and the rack gear (363) according to the rotation of the motor (361), but various other examples may be possible. According to a non-limiting embodiment, the driving unit (360) may operate in a passive manner. For example, the driving unit (360) may include a structure for providing movement of the second housing part (220) relative to the first housing part (210) by an external force. As an example of a passive manner, the driving unit (360) may include a guide member for guiding movement of the second housing part (220) relative to the first housing part (210) when an external force provided by a user is applied. In a non-limiting embodiment, the driving unit (360) may operate in a semi-automatic manner. As an example of a semi-automatic manner, the driving unit (360) may include an elastic member (e.g., a torsion spring) that is compressed or stretched by the second housing part (220) and a locking member for fixing the position of the second housing part (220). For example, the driving unit (360) may operate in a manner that, based on a user input, releases the fixation of the second housing part (220) by the locking member and provides movement of the second housing part (220) as the fixation of the second housing part (220) is released. In addition to the examples described above, various embodiments of the driving unit (360) for providing movement of the second housing part (220) with respect to the first housing part (210) may be possible.

[0139] According to one embodiment, the electronic device (101) may include a first antenna (510) and a second antenna (520). The first antenna (510) and the second antenna (520) may be used to identify an angle of arrival of a signal received from an external electronic device (501). According to one embodiment, at least one processor (120) may calculate the angle of arrival based on a first signal received from the external electronic device (501) through the first antenna (510) and a second signal received from the external electronic device (501) through the second antenna (520). Based on the angle of arrival, the at least one processor (120) may identify a direction of the external electronic device (501) with respect to the electronic device (101) (see the description of FIG. 5b). According to one embodiment, at least one processor (120) may identify a distance of the external electronic device (501) to the electronic device (101) based on a signal transmitted and / or received from the external electronic device (501) via the first antenna (510) and / or the second antenna (520) (see description of FIG. 5c).

[0140] Referring to FIGS. 7A and 7B , the first antenna (510) and the second antenna (520) may be disposed on different housing parts, respectively. For example, the first antenna (510) may be disposed on a fixed first housing part (210), and the second antenna (520) may be disposed on a movable second housing part (220) relative to the first housing part (210). However, the present invention is not limited thereto. For example, the first antenna (510) may be disposed on a second housing part (220), and the second antenna (520) may be disposed on the first housing part (210).

[0141] According to one embodiment, a printed circuit board (710) may be disposed on the second housing part (220). The printed circuit board (710) may include a plurality of conductive layers and a plurality of non-conductive layers alternately laminated with the plurality of conductive layers. The printed circuit board (710) may provide electrical connections between electronic components using wires and conductive vias formed on the conductive layers. For example, at least one processor (120), a wireless communication circuit (192), and a second antenna (520) may be disposed on the printed circuit board (710). The first antenna (510) disposed on the first housing part (210) may be spaced apart from the printed circuit board (710). The first antenna (510) may be electrically connected to the printed circuit board (710) via a connecting member (720). The first antenna (510) can be electrically connected to at least one processor (120) and wireless communication circuit (192) via a printed circuit board (710) and a connecting member (720).

[0142] According to one embodiment, the connecting member (720) may include, but is not limited to, a flexible printed circuit board and / or a coaxial cable for electrically connecting the printed circuit board (710) and the first antenna (510). The connecting member (720) may have flexibility. In the first state, at least a portion of the connecting member (720) may be bendable. However, the present invention is not limited thereto. The printed circuit board (710) may be disposed within the first housing part (210). In this case, the first antenna (510) may also be disposed on the printed circuit board (710).

[0143] According to one embodiment, the distance between the first antenna (510) and the second antenna (520) can be changed based on the position of the second housing part (220) with respect to the first housing part (210). Referring to FIG. 7A, within the first state, the distance between the first antenna (510) disposed on the first housing part (210) and the second antenna (520) disposed on the second housing part (220) can be a minimum. For example, within the first state, the distance can be, but is not limited to, a (e.g., about 15 mm). The memory (130) can store information related to the distance within the first state. At least one processor (120) can obtain information related to the distance within the first state.

[0144] Referring to FIG. 7B, as the state of the electronic device (101) changes from the first state to the second state, the distance between the first antenna (510) and the second antenna (520) may change. For example, in order to change the electronic device (101) to the second state, at least one processor (120) may control a driving unit (e.g., the driving unit (360) of FIG. 6). By the operation of the driving unit (360), the second housing part (220) may move with respect to the first housing part (210). When the second housing part (220) moves, at least a portion of the connecting member (720) that was bent in the first state may unfold. As the second housing part (220) moves, the position of the second housing part (220) may change.

[0145] According to one embodiment, at least one processor (120) may obtain information related to the position of the second housing part (220) within the second state. For example, at least one processor (120) may identify a rotation angle of a motor (e.g., motor (361) of FIG. 6). Based on the identified rotation angle of the motor (361), at least one processor (120) may identify a movement length of the second housing part (220) corresponding to the rotation angle. However, the present invention is not limited thereto. For example, when changing from the first state to the second state, the distance between the first antenna (510) and the second antenna (520) may be b. The at least one processor (120) may identify that the distance is (b) mm within the second state. Although not illustrated, the at least one processor (120) may identify the distance within an intermediate state between the first state and the second state. For example, within an intermediate state where the position of the second housing part (220) relative to the first housing part (210) is c, at least one processor (120) can identify that the distance between the first antenna (510) and the second antenna (520) is (a+c) mm.

[0146] According to one embodiment, the memory (130) may include one or more storage media for storing instructions. Each of the flow charts described below may be performed by executing computer-executable instructions by at least one processor (120). According to one embodiment, the memory (130) may store position values ​​of the second housing part (220) indicating the position of the second housing part (220), each corresponding to a plurality of UWB channels.

[0147] For example, the UWB frequency may be distinguished into multiple channels (e.g., channel 0 to channel 15) according to the frequency band defined in the UWB standard. Each of the multiple UWB channels may be assigned a designated channel number. Since each of the multiple UWB channels has a different frequency band, the optimal distance between the first antenna (510) and the second antenna (520) may vary depending on the channel number.

[0148] The position values ​​of the second housing part (220), which respectively correspond to the plurality of UWB channels, may be determined based on the frequency band of each of the plurality of UWB channels. For example, when the center frequency of channel 9 is approximately 7987.2 MHz and the bandwidth is approximately 499.2 MHz, the optimal distance between the first antenna (510) and the second antenna (520) may be approximately 18.8 mm, which corresponds to approximately 1 / 2 of the wavelength corresponding to the center frequency. The memory (130) may store information about the optimal distance of 18.8 mm corresponding to channel 9. In addition, the memory (130) may include information related to the optimal distance between the first antenna (510) and the second antenna (520), which correspond to each of the plurality of UWB channels.

[0149] According to one embodiment, the third antenna (530) may be disposed on the second housing part (220). For example, when the first antenna (510) and the second antenna (520) are disposed to be aligned, the third antenna (530) may be used to identify whether the direction of the external electronic device (501) is left or right. For example, the third antenna (530) may be misaligned with at least one of the first antenna (510) or the second antenna (520). When the first antenna (510) and the second antenna (520) are aligned, the direction of the external electronic device (501) with respect to the electronic device (101) may be identified, but since it is not possible to distinguish whether it is left or right or upward or downward, the electronic device (101) may use the third antenna (530) as an auxiliary means to provide additional information about the direction. The third antenna (530) may also be omitted.

[0150] An electronic device (101) according to one embodiment may perform communication with an external electronic device (501). The communication may be performed based on the establishment of BLE communication. After the BLE communication is established, the electronic device (101) may establish a specific channel among a plurality of UWB channels to receive a signal for identifying the direction and / or distance of the external electronic device (501). According to one embodiment, the electronic device (101) may be configured to control the driving unit (360) so that the position of the second housing part (220) corresponds to a position value corresponding to a specific channel. Hereinafter, the operation of the electronic device (101) will be described.

[0151] FIG. 8A is a flowchart illustrating an operation for adjusting the distance between a first antenna and a second antenna of an electronic device according to one embodiment. FIG. 8B illustrates an electronic device according to one embodiment for adjusting a sliding length. FIG. 8C is a flowchart illustrating an operation for adjusting the distance between a first antenna and a second antenna of an electronic device according to an external electronic device according to one embodiment.

[0152] The operations described in FIGS. 8A and 8C may be operations performed by an electronic device (e.g., an electronic device (101) of FIG. 6) when instructions stored in a memory (e.g., a memory (130) of FIG. 6) are executed by at least one processor (e.g., at least one processor (120) of FIG. 6).

[0153] Referring to FIG. 8A, at operation 801, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to establish a first channel among a plurality of UWB channels with an external electronic device (e.g., the external electronic device (501) of FIG. 5A).

[0154] According to one embodiment, the external electronic device (501) may be capable of utilizing multiple channels among multiple UWB channels (e.g., channels 0 to 15). For example, the external electronic device (501) may support two or more channels among channels 0 to 15.

[0155] According to one embodiment, at least one processor (120) may be configured to establish a first UWB channel based on the quality of a signal received from support channels available to the external electronic device (501). The operation of determining the first channel among the plurality of UWB channels is described below with reference to FIG. 9.

[0156] At operation 803, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify a position value of a second housing part (220) corresponding to a first channel.

[0157] According to one embodiment, the position value of the second housing part (220) corresponding to the first channel may be determined based on the frequency band of the first UWB channel. For example, the position value of the second housing part (220) corresponding to the first channel may be referenced as the position of the second housing part (220) with respect to the first housing part (210) such that the distance between the first antenna (e.g., the first antenna (510) of FIG. 6) and the second antenna (e.g., the second antenna (520) of FIG. 6) corresponds to an optimal distance or an acceptable distance. The position of the second housing part (220) such that the distance between the first antenna (510) and the second antenna (520) corresponds to the optimal distance may be identified based on the first position value stored in the memory (130). The position of the second housing part (220) that causes the distance between the first antenna (510) and the second antenna (520) to correspond to the allowable distance can be identified based on the second position value stored in the memory (130). At least one processor (120) can be configured to control the driving unit (e.g., the driving unit (360) of FIG. 6) according to the position value stored in the memory (130).

[0158] Each of the UWB channels may have a center frequency and a bandwidth. When the wavelength corresponding to the center frequency is w, the optimal distance between the first antenna (510) and the second antenna (520) may be referred to as w / 2. When the distance between the first antenna (510) and the second antenna (520) corresponds to the optimal distance, the angle of arrival can be accurately identified. Even if the distance between the first antenna (510) and the second antenna (520) is not the optimal distance, if it is included in a range specified based on the optimal distance, the direction of the external electronic device (501) with respect to the electronic device (101) may be identified based on the angle of arrival. For example, when the field of view (FoV) of the antenna is reduced, the direction of the external electronic device (501) with respect to the electronic device (101) may be identified even if the distance deviates from the optimal distance by a specified range. A distance within a specified range from the optimal distance may be referred to as an allowable distance, in terms of the distance between the first antenna (510) and the second antenna (520) that can identify the direction of the external electronic device (501) with respect to the electronic device (101). Table 1 below is a table showing the center frequency, bandwidth, optimal distance (e.g., w / 2), and allowable distance for UWB channels.

[0159] Channel numberCenter frequency(MHz)Band width(MHz)w / 2(mm)Allowable distance(mm)0399.2499.2300.5295.5 ~ 305.513494.4499.242.937.9 ~ 47.923993.6499.237.632.6 ~ 42.634492.8499.233.428.4 ~ 38.443993.61331.237.632.6 ~ 42.656489.6499.223.118.1 ~ 28.166988.8499.221.516.5 ~ 26.576489.61081.623.118.1 ~ 28.187488.0499.220.015.0 ~ 25.097987.2499.218.813.8 ~ 23.8108464.4499.217.712.7 ~ 22.7117982.21331.218.813.8 ~ 23.8128985.6499.216.711.7 ~ 21.7139484.8499.215.810.8 ~ 20.8149984.0499.215.010.0 ~ 20.0159484.81354.9715.810.8 ~ 20.8

[0160] Channel 0 is a sub-GHz band, channels 1 to 4 are low bands, and channels 5 to 15 are mid-high bands. Referring to Table 1, when the distance between the first antenna (510) and the second antenna (520) substantially corresponds to w / 2, the accuracy of identification of the angle of arrival can be improved. When the accuracy of identification of the angle of arrival is improved, the accuracy of identification of the direction and / or distance of the external electronic device (501) with respect to the electronic device (101) can be improved. When the distance substantially corresponds to w / 2, the distance may be referred to as a distance less than w / 2, but is not limited thereto. Even if the distance does not substantially correspond to w / 2, if it is included within the allowable distance, identification of the direction of the external electronic device (501) with respect to the electronic device (101) can be possible. The allowable distance may be changed based on the FoV. The FoV of an antenna is the range over which the antenna can receive radio wave energy, and if the FoV is reduced, the allowable distance can be extended.

[0161] According to one embodiment, the memory (130) may store position values ​​of the second housing part (220) corresponding to each of a plurality of UWB channels. According to one embodiment, the position values ​​may include a first position value and a second position value, each of which is assigned to each of the plurality of UWB channels.

[0162] According to one embodiment, the first position value may be referenced as a position value of the second housing part (220) to adjust the distance between the first antenna (510) and the second antenna (520) to an optimal distance based on a wavelength corresponding to a center frequency of each of the plurality of UWB channels. For example, the first position value may be referenced as a position value of the second housing part (220) to make the distance between the first antenna (510) and the second antenna (520) substantially correspond to half of the wavelength corresponding to the center frequency of the UWB channel. For example, the first position value may be determined based on w / 2 in Table 1 above.

[0163] According to one embodiment, the position value of the second housing part (220) can be identified based on the distance (e.g., about 15 mm) between the first antenna (510) and the second antenna (520) in the first state. For example, since the position value of the second housing part (220) is 0 mm in the first state, by adding the adjustable position value of the second housing part (220) to the distance (e.g., about 15 mm) between the first antenna (510) and the second antenna (520) in the first state, the distance between the first antenna (510) and the second antenna (520) can be calculated. By subtracting the distance (e.g., about 15 mm) between the first antenna (510) and the second antenna (520) in the first state from the optimal distance or the limit value of the allowable distance, the position value of the second housing part (220) can be calculated. Below, specific examples are described, but the numbers described below are only exemplary and the embodiments are not limited thereto.

[0164] For example, if the first channel is channel 5 of Table 1, the center frequency may be about 6489.6 MHz, and half of the wavelength corresponding to the center frequency may be about 23.1 mm. If, in the first state, the distance between the first antenna (510) arranged in the first housing part (e.g., the first housing part (210) of FIG. 7A) and the second antenna (520) arranged in the second housing part (220) is about 15 mm, the first position value corresponding to channel 5 may be about 8.1 mm (e.g., 23.1 mm - 15 mm). The first position value may include a position value of about 8.1 mm for channel 5.

[0165] For example, if the first channel is channel 9 of Table 1, the center frequency may be about 7987.2 MHz, and half of the wavelength corresponding to the center frequency may be about 18.8 mm. If, in the first state, the distance between the first antenna (510) arranged in the first housing part (210) and the second antenna (520) arranged in the second housing part (220) is about 15 mm, the first position value corresponding to channel 9 may be about 3.8 mm (e.g., 18.8 mm - 15 mm). The first position value may include a position value of about 3.8 mm for channel 9.

[0166] According to one embodiment, the second position value may include a position value of the second housing part (220) that is included within a specified range from the first position value. For example, the position value of the second housing part (220) that is included within a specified range from the first position value may be referenced as a position value of the second housing part (220) that makes the distance between the first antenna (510) and the second antenna (520) fall within the allowable distance of Table 1. The second position value may be referenced as a position value of the second housing part (220) that makes the distance between the first antenna (510) and the second antenna (520) fall within a specified range from the optimal distance. For example, the second position value may be determined based on the allowable distance of Table 1. For example, the specified range may be about 5 mm, but is not limited thereto. If the specified range is approximately 5 mm, the second position value can be referred to as a range with (first position value +5 mm) as the upper limit and (first position value - 5 mm) as the lower limit.

[0167] For example, if the UWB channel is channel 5 of Table 1, the allowable distance may be about 18.1 mm (23.1 mm - 5 mm) to about 28.1 mm (23.1 mm + 5 mm). The second position value may include a position value that makes the distance between the first antenna (510) and the second antenna (520) for channel 5 fall within about 18.1 mm to about 28.1 mm. If, in the first state, the distance between the first antenna (510) disposed on the first housing part (210) and the second antenna (520) disposed on the second housing part (220) is about 15 mm, the second position value corresponding to channel 5 may be about 3.8 mm to about 13.1 mm. The second position value may include a position value of about 3.8 mm to about 13.1 mm for channel 5.

[0168] For example, if the first channel is channel 9 of Table 1, the allowable distance may be about 13.8 mm (18.8 mm - 5 mm) to about 23.8 (18.8 mm + 5 mm). The second position value may include a position value that makes the distance between the first antenna (510) and the second antenna (520) for channel 9 be within about 13.8 mm to about 23.8 mm. If, in the first state, the distance between the first antenna (510) disposed on the first housing part (210) and the second antenna (520) disposed on the second housing part (220) is about 15 mm, the second position value corresponding to channel 9 may be about 0 mm to about 8.8 mm. The second position value may include a position value of about 0 mm to about 8.8 mm for channel 9. As in channel 9, if the lower limit of the allowable distance is smaller than the distance between the first antenna (510) and the second antenna (520) in the first state, the position value cannot be smaller than 0 mm, so the lower limit of the second position value can be 0 mm.

[0169] According to one embodiment, in operation 803, the electronic device (101) may be configured to identify a position value of the second housing part (220) corresponding to the first channel established in operation 801. For example, at least one processor (120) may be configured to identify a position value of the second housing part (220) corresponding to the first channel based on a first position value or a second position value corresponding to the first channel, stored in the memory (130).

[0170] At operation 805, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to control the drive unit (360) to move the second housing part (220) relative to the first housing part (210), corresponding to the first channel.

[0171] According to one embodiment, at least one processor (120) can adjust the position of the second housing part (220) by controlling the driving unit (360). The at least one processor (120) can identify the position value of the second housing part (220) at the time of initiating communication. If the position value of the second housing part (220) at the time of initiating communication is different from the position value of the second housing part (220) corresponding to the first channel, the at least one processor (120) can be configured to control the driving unit (360) so that the position of the second housing part (220) corresponds to the position value corresponding to the first channel. For example, a motor (e.g., motor (361) of FIG. 6) can be rotated so that the position of the second housing part (220) corresponds to the position value corresponding to the first channel. At least one processor (120) may stop controlling the motor (361) based on identifying that the position of the second housing part (220) corresponds to the position value.

[0172] According to one embodiment, when the position of the second housing part (220) corresponds to the position value corresponding to the first channel, the distance between the first antenna (510) and the second antenna (520) may correspond to the optimal distance or the allowable distance. When at least one processor (120) controls the driving unit (360) to control according to the position value corresponding to the first channel, in a state where the second housing part (220) is moved by the driving unit (360) according to the position value corresponding to the first channel, the distance between the first antenna (510) and the second antenna (520) may correspond to the optimal distance or the allowable distance.

[0173] For example, if at least one processor (120) controls the motor (361) based on the first position value, the distance between the first antenna (510) and the second antenna (520) may correspond to the optimal distance. For example, if at least one processor (120) controls the motor (361) based on the second position value, the distance between the first antenna (510) and the second antenna (520) may correspond to the allowable distance. At least one processor (120) may be configured to control the driving unit (360) based on the first position value or the second position value according to a user setting.

[0174] Referring to FIG. 8B, the state (800a) of FIG. 8B may be referred to as a state in which the position of the second housing part (220) does not correspond to the first position value or the second position value. The state (800b) of FIG. 8B may be referred to as a state in which the position of the second housing part (220) corresponds to the first position value or the second position value.

[0175] According to one embodiment, within the state (800a), the distance (831) between the first antenna (510) and the second antenna (520) may be a distance at which it is difficult to accurately identify the angle of arrival of a signal received through the first channel. For example, the distance (831) may be a distance that deviates from the optimal distance and the allowable distance. When calculating the angle of arrival through a signal received using the first antenna (510) and the second antenna (520) spaced apart by the distance (831), the accuracy of the calculated angle of arrival may be degraded due to phase distortion of the signal and / or linearity of the deteriorated phase.

[0176] According to one embodiment, at least one processor (120) may be configured to control a driving unit (e.g., driving unit (360) of FIG. 6) such that the position of the second housing part (220) corresponds to the first position value or the second position value. For example, the second housing part (220) may slide by rotation of the motor (361). The at least one processor (120) may stop controlling the motor (361) based on identifying that the position of the second housing part (220) corresponds to the first position value or the second position value. Whether the at least one processor (120) performs control based on either the first position value or the second position value may be determined based on a user input.

[0177] According to one embodiment, when the position of the second housing part (220) corresponds to the first position value or the second position value, the state (800a) may be changed to the state (800b). In the state (800b), the distance (832) between the first antenna (510) and the second antenna (520) may substantially correspond to the optimal distance or may be included within the allowable distance. In the state (800b), the arrival angle of the signal received using the first antenna (510) and the second antenna (520) may be accurately calculated.

[0178] Referring again to FIG. 8A, at operation 807, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify an angle of arrival based on a signal received from an external electronic device (501).

[0179] According to one embodiment, when the position of the second housing part (220) corresponds to the first position value or the second position value, the distance between the first antenna (510) and the second antenna (520) may correspond to the optimal distance or the allowable distance. When the distance corresponds to the optimal distance, the phase distortion of the signal received from the external electronic device (501) is reduced, and the linearity of the phase is good, so that the angle of arrival can be accurately calculated. When the distance corresponds to the allowable distance, the FoV is reduced compared to the case of the optimal distance, but the angle of arrival can be accurately calculated. According to one embodiment, the electronic device (101) may accurately calculate the angle of arrival by identifying the angle of arrival of the signal received from the external electronic device (501) using the first antenna (510) and the second antenna (520) spaced apart by the optimal distance or the allowable distance. The electronic device (101) may accurately identify the position of the external electronic device (501) based on the angle of arrival.

[0180] Using the aforementioned operations, the electronic device (101) can adjust the distance between the first antenna (510) and the second antenna (520) by changing the position of the second housing part (220) when the channel changes according to the external electronic device (501). For example, the electronic device (101) can use the first channel to identify the direction of the first external electronic device (e.g., the first external electronic device (501a) of FIG. 5A). The electronic device (101) can position the second housing part (220) with respect to the first housing part (210) to provide a first distance between the first antenna (510) and the second antenna (520) in order to receive a UWB signal from the first external electronic device (501a) using the first channel. The electronic device (101) can position the second housing part (220) relative to the first housing part (210) to provide a second distance between the first antenna (510) and the second antenna (520) to receive a UWB signal from the second external electronic device (501b) using a second channel different from the first channel. The electronic device (101) can adjust the position of the second housing part (220) by controlling the driving unit (360). The above operations are described below with reference to FIG. 8C .

[0181] Referring to FIG. 8c, at operation 802, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify a first channel associated with a UWB signal to be received from a first external electronic device (501a).

[0182] According to one embodiment, at least one processor (120) may be configured to identify a first channel associated with a UWB signal to be received from the first external electronic device (501a) to identify a direction of the first external electronic device (501a). For example, the at least one processor (120) may receive information on support channels available to the first external electronic device (501a) among UWB channels using BLE communication. The at least one processor (120) may identify the first channel among the support channels. For example, the at least one processor (120) may identify the first channel based on the quality of a signal received through each of the support channels.

[0183] At operation 804, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to adjust the position of the second housing part (220) to provide a first distance between the first antenna (510) and the second antenna (520).

[0184] According to one embodiment, at least one processor (120) may position the second housing part (220) relative to the first housing part (210) such that a distance between the first antenna (510) and the second antenna (520) corresponds to a first distance. The at least one processor (120) may be configured to control the driving unit (360) to adjust the position of the second housing part (220). For example, the first distance may correspond to a first position value or a second position value. When the first distance corresponds to the first position value, the distance between the first antenna (510) and the second antenna (520) may correspond to an optimal distance for the first channel of Table 1. When the first distance corresponds to the second position value, the distance between the first antenna (510) and the second antenna (520) may fall within an allowable distance for the first channel of Table 1.

[0185] At step 806, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify an angle of arrival based on a UWB signal received from a first external electronic device (501a). Since the angle of arrival indicates a direction of the external first electronic device (501a) with respect to the electronic device (101), the electronic device (101) may identify a direction of the first external electronic device (501a).

[0186] According to one embodiment, at least one processor (120) may be configured to receive a first UWB signal from a first external electronic device (501a) through the first antenna (510) and a second UWB signal through the second antenna (520) within a state that provides a first distance between the first antenna (510) and the second antenna (520). The at least one processor (120) may be configured to identify an angle of arrival indicating a direction of the first external electronic device (501a) with respect to the electronic device (101) based on the first distance and a phase difference between the first UWB signal and the second USB signal. For example, the at least one processor (120) may identify the angle of arrival using the mathematical expression (1).

[0187] In order to identify the direction of the second external electronic device (501b) that is different from the first external electronic device (501a), the electronic device (101) can readjust the position of the second housing part (220) with respect to the first housing part (210).

[0188] At operation 808, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify a second channel associated with a UWB signal to be received from a second external electronic device (501b).

[0189] According to one embodiment, at least one processor (120) may be configured to identify a second channel associated with a UWB signal to be received from the second external electronic device (501b) to identify a direction of the second external electronic device (501b). For example, the at least one processor (120) may receive information on support channels available to the second external electronic device (501b) among UWB channels using BLE communication. The at least one processor (120) may identify a second channel among the support channels. For example, the at least one processor (120) may identify the second channel based on the quality of a signal received through each of the support channels.

[0190] At operation 810, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to adjust the position of the second housing part (220) to provide a second distance between the first antenna (510) and the second antenna (520).

[0191] According to one embodiment, at least one processor (120) may position the second housing part (220) relative to the first housing part (210) such that a distance between the first antenna (510) and the second antenna (520) corresponds to a second distance. The at least one processor (120) may be configured to control the driver (360) to adjust the position of the second housing part (220). For example, the second distance may correspond to the first position value or the second position value. When the second distance corresponds to the first position value, the distance between the first antenna (510) and the second antenna (520) may correspond to an optimal distance for the second channel of Table 1. When the second distance corresponds to the second position value, the distance between the first antenna (510) and the second antenna (520) may fall within an allowable distance for the second channel of Table 1.

[0192] At operation 812, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify an angle of arrival based on a UWB signal received from a second external electronic device (501b). Since the angle of arrival indicates a direction of the second external electronic device (501b) with respect to the electronic device (101), the electronic device (101) may identify a direction of the second external electronic device (501b).

[0193] An electronic device (101) according to one embodiment can adjust the distance between a first antenna (510) and a second antenna (520) to identify the direction of an external electronic device (501). When the distance corresponds to an optimal distance or is within an allowable distance, the accuracy of the direction can be improved. An electronic device (101) according to one embodiment can accurately identify the location of an external electronic device (501).

[0194] FIG. 9 is a flowchart illustrating an operation of an electronic device according to one embodiment of the present invention to determine a UWB channel.

[0195] The operations of the electronic device described in FIG. 9 (e.g., the electronic device (101) of FIG. 6) may be operations performed by the electronic device (101) when instructions stored in a memory (e.g., the memory (130) of FIG. 6) are executed by at least one processor (e.g., at least one processor (120) of FIG. 6). The operations illustrated in FIG. 9 may be operations performed when the external electronic device (501) supports multiple channels.

[0196] Referring to FIG. 9, at operation 901, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to establish a BLE channel.

[0197] According to one embodiment, at least one processor (120) may be configured to establish a BLE channel with an external electronic device (501).

[0198] At operation 902, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to receive a signal from an external electronic device (501) via each of the support channels, including a first support channel and a second support channel.

[0199] According to one embodiment, the external electronic device (501) can communicate with the electronic device (101) using some of the plurality of UWB channels. The external electronic device (501) can use two or more support channels, including a first support channel and a second support channel, among the plurality of UWB channels. For example, the external electronic device (501) can be configured to support channels 5 and 9 among the plurality of UWB channels. The external electronic device (501) can transmit a signal to the electronic device (101) through each of the support channels supported by the external electronic device (501). The electronic device (101) can receive a signal through each of the first support channel and the second support channel.

[0200] At operation 903, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify a quality of a signal received via each of the supported channels.

[0201] According to one embodiment, at least one processor (120) may be configured to identify a first quality of a signal received via a first support channel. At least one processor (120) may be configured to identify a second quality of a signal received via a second support channel.

[0202] The signal received through each of the support channels may have a quality determined based on the communication environment. For example, if there are too many signals transmitted and received through a specific channel among the support channels supported by the external electronic device (501), the quality of the signal received through the specific channel may deteriorate. In addition, the quality of the signal received through a specific channel may not always be constant and may change due to various factors in the communication environment. At least one processor (120) may be configured to identify the quality of the signal received through each of the support channels in order to determine a channel on which to receive a UWB signal for identifying the angle of arrival among the support channels available to the external electronic device (501).

[0203] According to one embodiment, the signal quality may be at least one of a received signal strength indicator (RSSI), a reference signal received power (RSRP), a beam reference signal received power (BRSRP), a reference signal received quality (RSRQ), a signal to interference and noise ratio (SINR), a carrier to interference and noise ratio (CINR), a signal to noise ratio (SNR), an error vector magnitude (EVM), a bit error rate (BER), or a block error rate (BLER). In addition to the examples described above, other terms having equivalent technical meanings or other metrics indicating channel quality may be used. In the present disclosure, high signal quality means a case where a signal quality value related to a signal magnitude is large or a signal quality value related to an error rate is small. A higher signal quality may mean that a smooth wireless communication environment is guaranteed.

[0204] At operation 904, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to determine a priority of the supported channels based on quality.

[0205] According to one embodiment, at least one processor (120) may be configured to determine priorities for support channels based on the quality of signals received through each of the support channels. The priorities may be determined sequentially based on the signal quality. For example, at least one processor (120) may compare a first quality of a signal received through a first support channel with a second quality of a signal received through a second support channel, and prioritize a channel exhibiting a higher quality, and prioritize a channel exhibiting a lower quality.

[0206] For example, when an external electronic device (501) can use channel 5 and channel 9, at least one processor (120) may be configured to identify the quality of a signal received through channel 5 and the quality of a signal received through channel 9. The quality of the signal received through channel 5 may indicate the quality of channel 5. The quality of the signal received through channel 9 may indicate the quality of channel 9. The at least one processor (120) may compare the quality of the signal received through channel 5 and the quality of the signal received through channel 9, and determine a channel with a higher quality as a priority, and a channel with a lower quality as a lower priority. For example, when the quality of the signal received through channel 5 is higher than the quality of the signal received through channel 9, the at least one processor (120) may be configured to determine channel 5 as a priority (e.g., a first priority) and channel 9 as a lower priority (e.g., a second priority).

[0207] At operation 905, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to transmit priority information related to the priority to an external electronic device (501).

[0208] According to one embodiment, at least one processor (120) may be configured to transmit ranking information related to the ranking to an external electronic device (501).

[0209] In operation 906, the external electronic device (501) may be configured to determine a first channel based on rank information received from the electronic device (101).

[0210] According to one embodiment, the external electronic device (501) may be configured to receive ranking information from the electronic device (101). The ranking information may indicate a ranking determined for each of the support channels provided by the external electronic device (501).

[0211] According to one embodiment, the external electronic device (501) may be configured to determine a first channel used for transmitting a UWB signal to the external electronic device (501) based on the rank information. For example, if the external electronic device (501) has channels 5 and 9 available, the rank information may indicate ranks determined for each of channels 5 and 9. If the rank determined for channel 5 has a higher rank and the rank determined for channel 9 has a lower rank, the external electronic device (501) may be configured to determine channel 5 as the first channel. Since the communication quality of channel 5 is higher than that of channel 9 at the timing when the electronic device (101) identifies the quality, when the external electronic device (501) transmits a UWB signal to the electronic device (101) through channel 5, the electronic device (101) may receive a UWB signal with a smaller error rate and a higher reception strength.

[0212] At operation 907, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to receive selection information indicating a first channel.

[0213] According to one embodiment, the external electronic device (501) may be configured to transmit selection information indicating the first channel determined in operation 906 to the electronic device (101). At least one processor (120) may be configured to receive selection information indicating the first channel from the external electronic device (501). The selection information may include information such as a channel number for distinguishing the first channel among a plurality of UWB channels.

[0214] At operation 908, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify a first channel based on selection information.

[0215] According to one embodiment, at least one processor (120) may be configured to identify a first channel based on received selection information. The at least one processor (120) may be configured to identify a first channel indicated by the selection information and establish the identified first channel. For example, if the selection information indicates channel 5 among a plurality of UWB channels, the at least one processor (120) may be configured to identify channel 5 and establish channel 5 with the external electronic device (501). After channel 5 is established, the electronic device (101) may receive a UWB signal transmitted from the external electronic device (501) through channel 5. The electronic device (101) may identify an angle of arrival based on a signal received by a first antenna (e.g., a first antenna (510) of FIG. 6) and a signal received by a second antenna (e.g., a second antenna (520) of FIG. 6). The electronic device (101) can identify the direction and / or distance of the external electronic device (501) relative to the electronic device (101) based on the angle of arrival. The electronic device (101) can identify the location of the external electronic device (501) based on the angle and / or the distance.

[0216] As described above, when there are multiple support channels that the external electronic device (501) can support, the electronic device (101) may be configured to receive a UWB signal from the external electronic device (501) through a first channel having the highest quality among the support channels. According to one embodiment, the electronic device (101) may receive a UWB signal from the external electronic device (501) using the UWB channel having the highest quality according to the communication environment, thereby accurately identifying the angle of arrival. As the accuracy of the angle of arrival increases, the direction and distance of the external electronic device (501) may be accurately identified.

[0217] Fig. 10 is a flowchart showing the operation of an electronic device that distinguishes the first antenna and the second antenna as a main antenna and a sub antenna.

[0218] The operations described in FIG. 10 may be operations performed by an electronic device (e.g., an electronic device (101) of FIG. 6) when instructions stored in a memory (e.g., a memory (130) of FIG. 6) are executed by at least one processor (e.g., at least one processor (120) of FIG. 6).

[0219] Referring to FIG. 10, at operation 1001, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify a first quality of a first signal received by a first antenna (e.g., the first antenna (510) of FIG. 6) via a first channel.

[0220] According to one embodiment, after a first channel is established, at least one processor (120) may receive a signal from an external electronic device (e.g., an external electronic device (501) of FIG. 5A) via a first antenna (e.g., a first antenna (510) of FIG. 6) and a second antenna (e.g., a second antenna (520) of FIG. 6). A signal received via the first antenna (510) may be referred to as a first signal, and a signal received via the second antenna (520) may be referred to as a second signal. As described above, the first signal and the second signal are only distinguished based on the receiving antenna. At least one processor (120) may be configured to identify the quality of the first signal.

[0221] At operation 1003, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify a second quality of a second signal received via a first channel to a second antenna (e.g., the second antenna (520) of FIG. 6 ).

[0222] Although operations 1001 and 1003 are described in the order of FIG. 10, the order of operations 1001 and 1003 is not limited thereto and may be independent. The operation of identifying the first quality and the operation of identifying the second quality by at least one processor (120) are not limited to the order. For example, when an external electronic device (501) transmits a signal, the first antenna (510) and the second antenna (520) may receive the signal substantially simultaneously. The timing of identifying the first quality and the timing of identifying the second quality by at least one processor (120) may be performed substantially simultaneously or sequentially.

[0223] At operation 1005, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to identify a higher quality among the first quality and the second quality.

[0224] According to one embodiment, at least one processor (120) may be configured to compare a first quality and a second quality and identify a higher quality among the first quality and the second quality. For example, at least one processor (120) may compare a first RSSI value indicating the reception strength of a first signal and a second RSSI value indicating the reception strength of a second signal, and identify a signal having a higher RSSI value. However, the present invention is not limited thereto. For example, if the first quality is higher than the second quality, operation 1007 may be performed. For example, if the second quality is higher than the first quality, operation 1009 may be performed.

[0225] At operation 1007, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to use the first antenna (510) as an antenna for transmitting and receiving, and to use the second antenna (520) as an antenna for receiving.

[0226] According to one embodiment, an antenna used as an antenna for transmitting and receiving signals may be referred to as a main antenna, and an antenna used as an antenna for receiving signals may be referred to as a sub-antenna. According to one embodiment, the electronic device (101) may be configured to provide antenna switching diversity using a plurality of antennas. Antenna switching diversity is a technology for adaptively selecting an antenna to be used for communication among a plurality of antennas. For example, the electronic device (101) may change an antenna for receiving signals due to environmental factors (e.g., electric field conditions or usage conditions). For example, a sub-antenna may be used as a dedicated antenna for switching of a main antenna for receiving signals. For example, a sub-antenna may be referred to as an antenna for receiving diversity.

[0227] According to one embodiment, at least one processor (120) may be configured to use an antenna that receives a relatively high quality signal as a main antenna and an antenna that receives a relatively low quality signal as a sub-antenna. In operation 1007, at least one processor (120) may be configured to use the first antenna (510) as a main antenna and the second antenna (520) as a sub-antenna based on identifying a first quality that is higher than a second quality.

[0228] At operation 1009, the instructions, when executed by at least one processor (120), may cause the electronic device (101) to use the second antenna (520) as an antenna for transmitting and receiving and to use the first antenna (510) as an antenna for receiving.

[0229] According to one embodiment, at least one processor (120) may be configured to use the second antenna (520) as a main antenna and the first antenna (510) as a sub-antenna based on identifying a second quality that is higher than the first quality.

[0230] According to one embodiment, the electronic device (101) may have first and second qualities that may change as the position of the second housing part (e.g., the second housing part (220) of FIG. 5A) changes. Referring again to FIG. 8B, the second housing part (220) may include conductive portions (811, 812) defining at least a portion of a side surface for legacy network communication. For example, referring to FIG. 8B, the second housing part (220) may include a first conductive portion (811) and / or a second conductive portion (812). The length of the first conductive portion (811) and / or the second conductive portion (812) may be determined by non-conductive portions (821, 822, 823). Both ends of the first conductive portion (811) may be in contact with the first non-conductive portion (821) and the second non-conductive portion (822), respectively. Both ends of the second conductive portion (812) may be in contact with the second non-conductive portion (822) and the third non-conductive portion (823), respectively. At least a portion of the first conductive portion (811) and / or at least a portion of the second conductive portion (812) may be configured to operate as an antenna radiator for a legacy network.

[0231] According to one embodiment, the distance between the second housing part (220) and the first antenna (510) may change as the state (800a) of FIG. 8B changes to the state (800b) of FIG. 8B. For example, the distance between the second housing part (220) and the first antenna (510) in the state (800a) may be closer than the distance between the second housing part (220) and the first antenna (510) in the state (800b). The change in the distance may affect the quality of the first signal received through the first antenna (510). For example, the interference of the first conductive part (811) on a signal received by the first antenna (510) in the state (800a) where the distance is relatively close may be greater than the interference of the first conductive part (811) on a signal received by the first antenna (510) in the state (800b) where the distance is relatively far. When changing from the state (800a) to the state (800b), the first quality of the first signal may be improved as the interference is reduced. However, the present invention is not limited thereto, and the first quality and the second quality may change due to various factors. The electronic device (101) according to one embodiment may improve communication performance by adjusting the position of the second housing part (220) based on the first channel and then determining the main antenna and the sub-antenna according to the quality of the signal.

[0232] FIG. 11A is a block diagram of a memory according to one embodiment. FIGS. 11B, 11C, 11D, 11E, and 11F illustrate screens provided through a display of an electronic device according to one embodiment.

[0233] Referring to FIG. 11A, the memory (130) may store a first position value (1100a) and a second position value (1100b). As described above, the first position value (1100a) may be referenced as a position of the second housing part (220) for providing an optimal distance corresponding to each of the plurality of UWB channels. The optimal distance may be referenced as a distance between the first antenna (e.g., antenna (510) of FIG. 6) and the second antenna (e.g., antenna (520) of FIG. 6) that substantially corresponds to half of the wavelength corresponding to the center frequency of each of the plurality of UWB channels. The second position value (1100b) may be referenced as a position value of the second housing part (220) that is included within a range specified from the first position value (1100a).

[0234] According to one embodiment, at least one processor (120) may be configured to control a driving unit (e.g., driving unit (360) of FIG. 6) based on a first position value (1100a) or a second position value (1100b) stored in a memory (130). For example, when at least one processor (120) controls the driving unit (360) based on the first position value (1100a), at least one processor (120) may be configured to control the driving unit (360) such that a distance between the first antenna (510) and the second antenna (520) corresponds to an optimal distance. For example, when at least one processor (120) controls the driving unit (360) based on the second position value (1100b), the at least one processor (120) may be configured to control the driving unit (360) so that the distance between the first antenna (510) and the second antenna (520) is within a range specified from the optimal distance. According to one embodiment, a user may provide a user input to set the at least one processor (120) to operate based on either the first position value (1100a) or the second position value (1100b). The at least one processor (120) may be configured to control the driving unit (360) based on the first position value (1100a) or the second position value (1100b) according to a user setting according to the user input.

[0235] According to one embodiment, the position values ​​(e.g., the first position value (1100a) and / or the second position value (1100b)) can be modified by a user's self-calibration. For example, the user can place a tag including an antenna (e.g., the antenna (502) of FIG. 5A) at a location where the angle between the first antenna (510) and the second antenna (520) is substantially 0 degrees, and then identify the angle of arrival using the first antenna (510) and the second antenna (520). The user can input update information to change the first position value (1100a) and / or the second position value (1100b) stored in the memory (130) so that the identified angle of arrival becomes 0. According to one embodiment, at least one processor (120) can obtain the update information for changing the first position value (1100a) and / or the second position value (1100b) stored in the memory (130). The at least one processor (120) can be configured to change the first position value (1100a) and / or the second position value (1100b) stored in the memory (130) based on the update information. After the first position value (1100a) and / or the second position value (1100b) is updated, the at least one processor (120) can control the motor (361) based on the changed first position value (1100a) or the changed second position value (1100b).

[0236] Referring to FIG. 11B, the flexible display (230) can display a screen (1101) on which an application for detecting the location of an external electronic device (501) is executed through an angle of a signal received from the external electronic device (e.g., the external electronic device (501) of FIG. 5A). The application, when executed by at least one processor (120), can cause the electronic device (101) to display the screen (1101) through the flexible display (230).

[0237] Referring to the above screen (1101), when executing an application, the electronic device (101) may provide text (1111) such as “Move to find the device” through the flexible display (230). When receiving a signal from an external electronic device (501), the electronic device (101) may display visual objects for selecting a control mode of a driving unit (e.g., driving unit (360) of FIG. 6) that causes movement of the second housing part (220) through the flexible display (230). According to one embodiment, the visual objects may include a first visual object (1112), a second visual object (1113), a third visual object (1114), and / or a fourth visual object (1115).

[0238] According to one embodiment, the first visual object (1112) may be a visual object for selecting a first mode for controlling the driving unit (360) based on the first position value. For example, the first visual object (1112) may include text such as, but not limited to, “Quick Find” to intuitively indicate the first mode. The first mode may be activated based on a first user input to the first visual object (1112). For example, at least one processor (120) may be configured to control the driving unit (360) based on the first position value in response to the first user input to the first visual object (1112). When the driving unit (360) is controlled based on the first position value, when receiving a signal from the external electronic device (501), at least one processor (120) can move the second housing part (220) so that the distance between the first antenna (e.g., the first antenna (510) of FIG. 6) and the second antenna (e.g., the second antenna (520) of FIG. 6) corresponds to the optimal distance of Table 1. In the first mode, at least one processor (120) can be configured to control the driving unit (360) so that the position of the second housing part (220) corresponds to the first position value. According to one embodiment, in the first mode, the distance between the first antenna (510) and the second antenna (520) corresponds to the optimal distance, so that the arrival angle of the signal received from the external electronic device (501) can be identified most accurately and quickly. Within the first mode, the direction and / or distance of the external electronic device (501) to the electronic device (101) can be accurately calculated, so that the location identification of the external electronic device (501) can be provided most accurately.

[0239] According to one embodiment, the second visual object (1113) may be a visual object for selecting a second mode for controlling the driving unit (360) based on the second position value. For example, the second visual object (1113) may include text such as, but not limited to, “minimum movement” to intuitively indicate the second mode. The second mode may be activated based on a second user input to the second visual object (1113). For example, at least one processor (120) may be configured to control the driving unit (360) based on the second position value in response to the second user input to the second visual object (1113). When the driving unit (360) is controlled based on the second position value, when receiving a signal from the external electronic device (501), at least one processor (120) can move the second housing part (220) so that the distance between the first antenna (510) and the second antenna (520) corresponds to the allowable distance of Table 1. In the second mode, at least one processor (120) can be configured to control the driving unit (360) so that the position of the second housing part (220) corresponds to the second position value. According to one embodiment, in the second mode, the distance between the first antenna (510) and the second antenna (520) corresponds to the allowable distance, so that the arrival angle of the signal received from the external electronic device (501) can be identified according to the FoV. The second mode can enable identification of the position of the external electronic device (501) although it has lower accuracy than the first mode.

[0240] According to one embodiment, the second mode can shorten the position adjustment time of the second housing part (220) compared to the first mode. For example, the time for the distance between the first antenna (510) and the second antenna (520) to be changed to an acceptable distance may be shorter than the time for the distance to be changed to an optimal distance. For example, when the first channel is channel 5 of Table 1, the optimal distance may be about 23.1 mm, and the acceptable distance may be about 18.1 mm to about 28.1 mm. It is assumed that at the timing when the application is executed, the upper value of the second housing part (220) is 0 mm (e.g., the first state of FIG. 2A), and within the first state, the distance between the first antenna (510) and the second antenna (520) is about 15.0 mm. In the first mode, since the first position value is about 8.1 mm (23.1 mm - 15 mm), at least one processor (120) may be configured to control the driving unit (360) until the position value of the second housing part (220) becomes about 8.1 mm. In the second mode, since the lower limit of the allowable distance is about 18.1 mm, at least one processor (120) may be configured to control the driving unit (360) until the position value of the second housing part (220) becomes about 3.1 mm (18.1 mm - 15 mm). If, at the timing when the application is executed, the first length is included within a range specified from the reference length, the distance between the first antenna (510) and the second antenna (520) is already included within the allowable distance, and therefore, at least one processor (120) may not control the driving unit (360). In this way, the second mode can minimize movement of the second housing part (220) by shortening the time required for position adjustment of the second housing part (220).

[0241] According to one embodiment, the third visual object (1114) may be a visual object for selecting a third mode that does not provide position adjustment of the second housing part (220) when identifying the arrival angle of a signal received from the external electronic device (501). The third mode may be referred to as a mode for receiving UWB signals without control of the driving unit (360). For example, the third visual object (1114) may include text such as, but not limited to, “maintain current state” to intuitively indicate the third mode. For example, at least one processor (120) may be configured to limit control of the driving unit (360) and identify the arrival angle according to a third user input to the third visual object (1114). Within the third mode, the at least one processor (120) may identify the arrival angle without moving the second housing part (220). In the third mode, the distance between the first antenna (510) and the second antenna (520) may not correspond to the optimal distance or may not be within the allowable distance, making it difficult or impossible to accurately identify the angle of arrival. The user can activate the third mode by providing a third user input to the third visual object (1114) so ​​that movement of the second housing part (220) does not occur.

[0242] According to one embodiment, the fourth visual object (1115) may be a visual object for selecting a fourth mode that controls the driving unit (360) in the order of the third mode, the second mode, and the first mode when identifying the arrival angle of a signal received from the external electronic device (501). For example, the fourth visual object (1115) may include text such as “3-2-1 order” to intuitively indicate the fourth mode, but is not limited thereto. The fourth mode may be activated based on a fourth user input to the fourth visual object (1115).

[0243] For example, at least one processor (120) may be configured to control the driving unit (360) in the order of a third mode, a second mode, and a first mode, according to a fourth user input for a fourth visual object (1115). Within the fourth mode, at least one processor (120) may first identify an arrival angle of a signal received from an external electronic device (501) within the third mode. If the arrival angle is not identified within the third mode, at least one processor (120) may change the third mode to a second mode, and identify the arrival angle within the second mode. If the arrival angle is not identified within the second mode, the second mode may change the second mode to a first mode, and identify the arrival angle within the first mode. The electronic device (101) according to one embodiment may provide various modes suitable for a user's preference and a current situation by operating in the first mode, the second mode, the third mode, and / or the fourth mode.

[0244] Referring to FIG. 11C, the electronic device (101) may identify an arrival angle of a signal received from an external electronic device (501) and provide a screen (1102) through the flexible display (230) to indicate a location of the external electronic device (501) based on the arrival angle. The electronic device (101) may identify a direction and / or a distance of the external electronic device (501) with respect to the electronic device (101) based on the arrival angle, and may identify a location of the external electronic device (501) based on the angle and / or distance. The screen (1102) may include a fifth visual object (1121) indicating a direction of the external electronic device (501) with respect to the electronic device (101) and a sixth visual object (1122) indicating a distance of the external electronic device (501) with respect to the electronic device (101). For example, the fifth visual object (1121) may include, but is not limited to, an image for guiding a direction toward the external electronic device (501) based on the location of the electronic device (101). For example, the sixth visual object (1122) may include, but is not limited to, text for indicating a distance of the external electronic device (501) with respect to the location of the electronic device (101). As illustrated in the screen (1102), the sixth visual object (1122) may include text indicating a distance value such as “2.4 m.” As the location of the electronic device (101) changes, the fifth visual object (1121) and the sixth visual object (1122) may change.

[0245] According to one embodiment, the fifth visual object (1121) and / or the sixth visual object (1122) may be configured to blink or change size periodically. The fifth visual object (1121) and / or the sixth visual object (1122) may indicate that the location of the external electronic device (501) is being searched by continuously blinking.

[0246] Referring to FIG. 11D, as a user holds the electronic device (101) and changes the orientation of the electronic device (101), the orientation of the external electronic device (501) with respect to the electronic device (101) may change. For example, the orientation of the electronic device (101) may change according to a change in the posture of the electronic device (101). At least one processor (120) may be configured to identify the changed orientation based on the arrival angle of a signal received from the external electronic device (501). The at least one processor (120) may change the fifth visual object (1121) to indicate the orientation through the flexible display (230). For example, referring to the screen (1103), the fifth visual object (1121) may include an image that is changed to indicate a direction toward the external electronic device (501) based on the changed position. Referring to screen (1103), since the electronic device (101) has not moved, the sixth visual object (1122) may include text indicating the same distance value as screen (1102) shown in FIG. 11c.

[0247] Referring to FIG. 11E, as a user moves while holding the electronic device (101), the direction and / or distance of the external electronic device (501) with respect to the electronic device (101) may change. At least one processor (120) may be configured to identify the changed direction and / or distance based on the arrival angle of a signal received from the external electronic device (501). The at least one processor (120) may change the fifth visual object (1121) and the sixth visual object (1122) to indicate the direction through the flexible display (230). For example, referring to the screen (1104), the fifth visual object (1121) may include an image that is changed to point in a direction toward the external electronic device (501) based on the changed position. Referring to the screen (1104), the sixth visual object (1122) may include text indicating a distance value with respect to the external electronic device (501) based on the changed position.

[0248] Referring to FIG. 11F, when the location of the electronic device (101) corresponds to the location of the external electronic device (501), the electronic device (101) may provide a screen (1105) to indicate that the current location is the location of the external electronic device (501). At least one processor (120) may identify that the location of the electronic device (101) corresponds to the location of the external electronic device (501) based on the arrival angle of a signal received from the external electronic device (501). At least one processor (120) may change the fifth visual object (1121) and the sixth visual object (1122) through the flexible display (230) to indicate that the location of the electronic device (101) corresponds to the location of the external electronic device (501). For example, referring to the screen (1105), the fifth visual object (1121) may include an image changed to indicate the current location. Referring to screen (1104), the sixth visual object (1122) may include text (e.g., STAY) indicating that the distance from the external electronic device (501) is within a certain range. When the location of the electronic device (101) corresponds to the location of the external electronic device (501), the blinking of the fifth visual object (1121) and / or the sixth visual object (1122) may stop.

[0249] An electronic device (101) according to one embodiment can provide enhanced user convenience by providing various modes for identifying an arrival angle received from an external electronic device (501). As described with reference to FIGS. 11B to 11F , the electronic device (101) can provide an enhanced user experience by providing a user interface (UI) indicating the location of the external electronic device (501).

[0250] In the above description, it has been described that the distance between the first antenna (510) and the second antenna (520) is adjusted by moving the second housing part (220) with respect to the first housing part (210), but it is not limited thereto. For example, when the first antenna (510) and the second antenna (520) are arranged within one housing part, or when the electronic device (101) does not include a plurality of movable housing parts, the electronic device (101) may include a driving unit for adjusting the distance between the first antenna (510) and the second antenna (520). For example, the electronic device (101) may also adjust the distance between the first antenna (510) and the second antenna (520) through the operation of the driving unit for adjusting the distance between the substrate on which the first antenna (510) is arranged and the substrate on which the second antenna (520) is arranged.

[0251] FIG. 12 illustrates a first state and a second state of an electronic device according to one embodiment.

[0252] In the above descriptions, the electronic device (101) has been described as a device having a structure that can move in a vertical direction (e.g., a direction parallel to the y-axis of FIG. 2A), but is not limited thereto. According to one embodiment, the electronic device (101) may be a device having a structure that can move in a horizontal direction (e.g., a direction parallel to the x-axis of FIG. 12). The electronic device (101) illustrated in FIG. 12 may be substantially the same as the electronic device (101) described above, except for the direction of movement of the second housing part (220). Identical components are given the same reference numerals, and redundant descriptions may be omitted.

[0253] Referring to FIG. 12, the electronic device (101) may include a housing (201) including a first housing part (210) and a second housing part (220). The display area of ​​the flexible display (230) may change based on the movement of the second housing part (220). For example, in a first state (1210) that is a slide-in state or a collapsed state, the flexible display (230) may include a first display area (230a). As the second housing part (220) slides in the +x direction, the display area of ​​the flexible display (230) may expand. For example, in a second state (1220) that is a slide-out or expanded state, the flexible display (230) may include a first display area (230a) and a second display area (230b). Within the first state (1210), the second display area (230b), which was at least partially bent within the second housing part (220), may be exposed to the outside as the electronic device (101) changes from the first state (1210) to the second state (1220). Within the second state (1220), as the second housing part (220) slides in the -x direction, the electronic device (101) may change from the second state (1220) to the first state (1210).

[0254] According to one embodiment, the electronic device (101) may include a first antenna (510) and a second antenna (520). The first antenna (510) may be disposed in the first housing part (210). The second antenna (520) may be disposed in the second housing part (220). As the second housing part (220) slides in a direction parallel to the x-axis, the distance between the first antenna (510) and the second antenna (520) may change. The electronic device (101) according to one embodiment may adjust the position of the second housing part (220) to adjust the distance between the first antenna (510) and the second antenna (520). As described above, the electronic device (101) may be configured to adjust the sliding length of the second housing part (220) to identify the arrival angle of a signal received from an external electronic device (501). By adjusting the position of the second housing part (220), the distance between the first antenna (510) and the second antenna (520) can correspond to an optimal distance or be included within an allowable distance. According to one embodiment, the electronic device (101) can accurately identify the position of the external electronic device (501) by accurately identifying the arrival angle.

[0255] Figure 13 illustrates an electronic device according to one embodiment.

[0256] Although the electronic device (101) described above has been described as a device including a housing (201) having a slidable structure, the structure of the electronic device (101) is not limited thereto. For example, the electronic device (101) may also be implemented as a foldable device. The electronic device (101) described below may be substantially the same as the electronic device (101) described above, except for the foldable structure. Components identical to the components described above may be given the same reference numerals, and redundant descriptions may be omitted.

[0257] Referring to FIG. 13, an electronic device (101) according to one embodiment may include a foldable housing. The foldable housing may include a first housing part (1310) and a second housing part (1320). The first housing part (1310) and the second housing part (220) may be rotatably coupled by a hinge assembly (1360). For example, the first housing part (1310) may be rotatable relative to the second housing part (1320) about a folding axis (f). For example, the electronic device (101) may be configured to provide a folded state (1301) in which the first housing part (1310) and the second housing part (1320) are unfolded, an unfolded state (1302) in which the first housing part (1310) and the second housing part (1320) are folded, and a plurality of intermediate states between the folded state (1301) and the unfolded state (1302).

[0258] According to one embodiment, the flexible display (1330) may include a first display area (1331), a second display area (1332), and a third display area (1333). The first display area (1331) may be supported by the first housing part (1310). The second display area (1332) may be supported by the second housing part (1320). The third display area (1333) may be positioned between the first display area (1331) and the second display area (1332). The third display area (1333) may be at least partially bendable based on the rotation of the first housing part (1310) or the second housing part (1320). According to one embodiment, the electronic device (101) may include a cover display (1350) that is visible from the outside in an unfolded state (1302).

[0259] An electronic device (101) according to one embodiment may include a first antenna (510) and a second antenna (520). The first antenna (510) may be disposed in a first housing part (1310). For example, the first antenna (510) may be disposed on a first printed circuit board (1341) within the first housing part (1310). The second antenna (520) may be disposed in a second housing part (1320). For example, the second antenna (520) may be disposed on a second printed circuit board (1342) within the second housing part (1320). The first printed circuit board (1341) and the second printed circuit board (1342) may be electrically connected via a connecting member (1343).

[0260] FIG. 14 illustrates a distance between a first antenna and a second antenna that changes depending on a folding angle of an electronic device according to one embodiment.

[0261] Referring to FIG. 14, depending on the state of the electronic device (101), the distance between the first antenna (510) and the second antenna (520) may change. For example, referring to the folded state (1301), since the first housing part (1301) and the second housing part (1320) are substantially arranged in parallel, the first distance (1401) between the first antenna (510) and the second antenna (520) may be maximum. As the state of the electronic device changes from the folded state (1301) to the intermediate state (1303), the second distance (1402) between the first antenna (510) and the second antenna (520) may be closer than the first distance (1401). For example, the second distance (1402) can be maintained within a free stop state in which the first housing part (1310) and the second housing part (1320) form a constant folding angle (1403) by the hinge assembly (1360). As the state of the electronic device (101) changes from the first state (1301) to the intermediate state (1303), the distance between the first antenna (510) and the second antenna (520) can change, so that the electronic device (101) can identify a distance at which it can accurately calculate the arrival angle of a signal received from an external electronic device (e.g., the external electronic device (501) of FIG. 5A). The electronic device (101) can provide a visual object for providing an optimal distance or an acceptable distance for the first channel through the flexible display (1330).

[0262] FIG. 15 illustrates an example of a visual object provided by an electronic device through a flexible display according to one embodiment.

[0263] Referring to FIG. 15, the electronic device (101) may display a visual object (1500) for providing a folding angle that makes the distance between the first antenna (510) and the second antenna (520) correspond to an optimal distance or fall within an acceptable distance, through the flexible display (1330). As described above, the distance between the first antenna (510) and the second antenna (520) may change according to the folding angle between the first housing part (1310) and the second housing part (1320). The electronic device (101) may identify a folding angle that makes the distance between the first antenna (510) and the second antenna (520) correspond to an optimal distance or fall within an acceptable distance, in order to identify an arrival angle of a signal received from an external electronic device (e.g., the external electronic device (501) of FIG. 5A). The electronic device (101) may display a visual object (1500) to guide the identified folding angle. For example, the visual object (1500) may include text such as, but not limited to, "For optimal distance, please fold at angle A."
