[0022] FIG. 15 is a block diagram of an electronic device within a network environment according to various embodiments.

[0023] FIG. 1 illustrates an example of an environment including an electronic device, a first external electronic device, and a second external electronic device.

[0024] Referring to FIG. 1, the environment (100) may include an electronic device (101), a first external electronic device (111), and a second external electronic device (112).

[0025] An electronic device (101) within an environment (100) may provide an audio broadcasting service (or broadcasting service) in conjunction with a first external electronic device (111). As a non-limiting example, the electronic device (101) may be configured to operate as an audio sync device within the audio broadcasting service. The first external electronic device (111) may be configured to assist the electronic device (101) in operating as an audio sync device within the audio broadcasting service.

[0026] For example, the electronic device (101) may be configured to output audio. For example, the electronic device (101) may output audio based on data broadcasted from a second external electronic device (112). For example, the electronic device (101) may provide an audio broadcasting service based on data broadcasted from the second external electronic device (112). As a non-limiting example, the second external electronic device (112) may be configured to operate as an audio source device within the audio broadcasting service.

[0027] For example, the electronic device (101) may output audio based on data for a broadcast isochronous stream (BIS) from a second external electronic device (112). For example, the audio may be broadcast via a broadcast isochronous group (BIG). For example, the BIG may include multiple instances for the BIS. For example, an event of the BIG may include one or more BIS events. For example, each of the one or more BIS events may include one or more sub-events. For example, the audio may be output based on synchronization with the BIS from the second external electronic device (112), as indicated by arrow (161). For example, synchronization with the BIS may indicate receiving the data for the BIS. For example, synchronization with the BIS may be performed based on synchronization with a periodic advertisement (142) of a second external electronic device (112).

[0028] A first external electronic device (111) within the environment (100) may be used to assist the electronic device (101) in synchronizing with the BIS. As a non-limiting example, the first external electronic device (111) may be configured to operate as an assistance device (or assistant device) of the electronic device (101) operating as an audio sync device within the audio broadcasting service. For example, the first external electronic device (111) may include at least a portion of the electronic device (1501) of FIG. 15 or may correspond to at least a portion of the electronic device (1501) of FIG. 15.

[0029] As a non-limiting example, the first external electronic device (111), unlike the electronic device (101), may include a display. For example, the first external electronic device (111) may be configured to display, on the display, a user interface for starting an audio broadcasting service (or broadcasting service). For example, the first external electronic device (111) may be configured to display, on the display, a user interface for searching for an audio source device that provides the audio broadcasting service. For example, the first external electronic device (111) may be configured to display, on the display, a user interface for visually presenting one or more audio source devices searched for the audio broadcasting service. For example, the first external electronic device (111) may be configured to display, on the display, a user interface for selecting an audio source device that provides audio output from the electronic device (101) within the audio broadcasting service. For example, the first external electronic device (111) may be used to receive user input for at least some of the user interfaces exemplified above. For example, the first external electronic device (111) may assist the electronic device (101) in synchronizing with the BIS through operations related to receiving the user input.

[0030] For example, the second external electronic device (112) may execute one or more advertisements (141) to provide the audio broadcasting service. For example, the one or more advertisements (141) may represent periodic advertisements (142) executed by the second external electronic device (112), as indicated by arrows (151). For example, at least one packet advertised from the second external electronic device (112) according to the one or more advertisements (141) may include information about the periodic advertisements (142). For example, the first external electronic device (111) may execute a scan for the one or more advertisements (141) in relation to the audio broadcasting service.

[0031] For example, the second external electronic device (112) may execute a periodic advertisement (142) to provide the audio broadcasting service. For example, the periodic advertisement (142) may indicate resources for broadcasting (143) the data for the BIS, as indicated by an arrow (152). For example, at least one packet advertised from the second external electronic device (112) according to the periodic advertisement (142) may include information about broadcasting (143) the data for the BIS (e.g., information about resources for broadcasting (143) the data for the BIS). For example, the first external electronic device (111) may execute a scan for the periodic advertisement (142) in relation to the audio broadcasting service.

[0032] For example, the first external electronic device (111) can transmit information about the result of the scan exemplified above (e.g., information about the periodic advertisement (142)) to the electronic device (101). For example, the information can be transmitted to the electronic device (101) through a communication link (131) between the electronic device (101) and the first external electronic device (111). For example, the communication link (131) can include an asynchronous connectionless link (ACL), which is a control data link. However, the present invention is not limited thereto. For example, the information can also be transmitted from the first external electronic device (111) to the electronic device (101) through a device (e.g., a cradle) for storing the electronic device (101) and charging the rechargeable battery of the electronic device (101).

[0033] A second external electronic device (112) within the environment (100) can broadcast the data for the BIS. Although not illustrated in FIG. 1, the second external electronic device (112) can execute one or more advertisements (141) to provide information for accessing the data for the BIS. For example, one or more advertisements (141) can provide information for accessing periodic advertisements (142). For example, the second external electronic device (112) can execute periodic advertisements (142) to provide information for accessing the data for the BIS. For example, the periodic advertisements (142) can provide information for accessing the data for the BIS broadcasted from the second external electronic device (112). For example, the electronic device (101) can synchronize with the BIS by accessing the data for the BIS (or receiving the data for the BIS).

[0034] As a non-limiting example, the environment (100) may further include another electronic device (102). For example, the other electronic device (102) may be a device paired with the electronic device (101). As a non-limiting example, the electronic device (101) may be worn on the user's right ear and the other electronic device (102) may be worn on the user's left ear. As a non-limiting example, the electronic device (101) paired with the other electronic device (102) may indicate that the electronic device (101) and the other electronic device (102) are configured as a set to provide an audio broadcasting service. As a non-limiting example, the electronic device (101) paired with the other electronic device (102) may indicate that the electronic device (101) and the other electronic device (102) are connected via a communication link (132). As a non-limiting example, an electronic device (101) paired with another electronic device (102) may indicate that the electronic device (101) and the other electronic device (102) are used for stereophonic sound. For example, audio output through a speaker of the electronic device (101) may correspond to audio output through a speaker of the other electronic device (102).

[0035] For example, another electronic device (102) may provide an audio broadcasting service in conjunction with the first external electronic device (111) and the electronic device (101). As a non-limiting example, the other electronic device (102) may be configured to operate as an audio sync device within the audio broadcasting service.

[0036] For example, the other electronic device (102) may be configured to output audio. For example, the other electronic device (102) may output audio based on data broadcast from the second external electronic device (112). For example, the other electronic device (102) may provide an audio broadcasting service based on data broadcast from the second external electronic device (112).

[0037] For example, the other electronic device (102) may output audio based on the data for the BIS from the second external electronic device (112). For example, the other electronic device (102) may output audio via one or more second BIS events within the event of the BIG while the electronic device (101) outputs audio via one or more first BIS events within the event of the BIG. For example, the audio output from the other electronic device (102) may be output based on synchronization with the BIS from the second external electronic device (112), as indicated by arrow (162). For example, synchronization with the BIS may indicate receiving the data for the BIS. For example, synchronization with the BIS may be performed based on synchronization with a periodic advertisement (142) of the second external electronic device (112). As a non-limiting example, the other electronic device (112) may receive information about the periodic advertisement (142) from the first external electronic device (111) via a communication link (133) between the other electronic device (102) and the first external electronic device (111) to synchronize with the periodic advertisement (142) of the second external electronic device (112). For example, the communication link (133) may include an ACL, which is a control data link.

[0038] As a non-limiting example, another electronic device (102) may be configured to perform at least some of the operations of the electronic device (101) as exemplified below.

[0039] As a non-limiting example, since the first external electronic device (111) includes a rechargeable battery having a capacity greater than (or greater than) the capacity of the rechargeable battery within the electronic device (101), it may be contemplated that the first external electronic device (111) performs the scan for one or more advertisements (141) instead of the electronic device (101) for the audio broadcasting service. For example, among the electronic device (101) and the first external electronic device (111), performing the scan for one or more advertisements (141) may result in an increase in the time until an audio source device (e.g., a second external electronic device (112)) (suitable for the user) is discovered.

[0040] For example, since the audio broadcasting service is provided by the electronic device (101) receiving data broadcasted from the second external electronic device (112) (e.g., the data for the BIS), the scanning of one or more advertisements (141) by the first external electronic device (111) among the electronic device (101) and the first external electronic device (111) may be independent of the path by which the electronic device (101) receives the data broadcasted from the second external electronic device (112).

[0041] As exemplified above, and as a non-limiting example, it may be considered that the electronic device (101) and the first external electronic device (111) additionally perform a scan to search for an audio source device that provides the audio broadcasting service, since the first external electronic device (111) among the electronic device (101) performs the scan for one or more advertisements (141) because this causes an increase in the time until searching for an audio source device and / or is independent of the path by which the electronic device (101) receives the data broadcast from the second external electronic device (112).

[0042] An electronic device (101), as exemplified by the descriptions below, can perform an additional scan for the audio broadcasting service. A first external electronic device (111), as exemplified by the descriptions below, can be used to cause the electronic device (101) to perform the additional scan. For example, the electronic device (101) may include components used to perform the additional scan, and the first external electronic device (111) may include components for causing the additional scan. The components of the first external electronic device (111) are exemplified in the description of FIG. 2 , and the components of the electronic device (101) are exemplified in the description of FIG. 3 .

[0049] The first external electronic device (111) exemplified in the description of FIG. 2 can execute at least some of the operations exemplified in the descriptions of FIGS. 4, 5, and 7 to 13. The operations of the first external electronic device (111) exemplified in the descriptions of FIGS. 4, 5, and 7 to 13 can be executed, caused, or controlled by the processor (201).

[0050] Figure 3 is a simplified block diagram of an exemplary electronic device.

[0051] Referring to FIG. 3, the electronic device (101) may include at least a portion of the electronic device (1502) of FIG. 15, or may correspond to at least a portion of the electronic device (1502) of FIG. 15. The electronic device (101) may include at least one processor (301), a communication circuit (302), a speaker (303), and a memory (304).

[0052] The processor (301) may be configured to control the communication circuit (302) and the speaker (303). The processor (301) may be configured to execute instructions stored in the memory (304) to cause the electronic device (101) to perform at least some of the operations exemplified in the description of FIG. 1. The processor (301) may be configured to execute instructions stored in the memory (304) to cause the electronic device (101) to perform at least some of the operations exemplified in the description of FIGS. 4 to 14.

[0053] The communication circuit (302) may support legacy Bluetooth and / or Bluetooth low energy (BLE). For example, the communication circuit (302) may be used for audio broadcasting services. For example, the communication circuit (302) may be used for communication with a first external electronic device (111) that operates as an auxiliary device for the audio broadcasting service. For example, the communication circuit (302) may be used for communication with a device that operates as an audio source device for the audio broadcasting service, such as a second external electronic device (112). For example, the communication circuit (302) may be used for communication with another electronic device (102) that operates as an audio sink device for the audio broadcasting service.

[0054] The speaker (303) may be configured to output audio. For example, the speaker (303) may be used for audio broadcasting services. For example, the speaker (303) may output audio provided from a second external electronic device (112).

[0055] The memory (304) may be configured to store instructions (or one or more programs that store instructions). For example, the memory (304) may include non-volatile memory.

[0056] The electronic device (101) illustrated in the description of FIG. 3 can execute at least some of the operations illustrated in the descriptions of FIGS. 4, 6, 13, and 14. The operations of the electronic device (101) illustrated in the descriptions of FIGS. 4, 6, 13, and 14 can be executed, caused, or controlled by the processor (301).

[0057] FIG. 4 illustrates an exemplary method for additional scanning performed by an electronic device acting as an audio sink device.

[0058] Referring to FIG. 4, in operation 401, a first external electronic device (111) may establish a communication link (e.g., communication link (131) of FIG. 1) with an electronic device (101).

[0059] As a non-limiting example, the communication link (131) may be established based on an input to a user interface displayed on the display (204) in accordance with an advertisement of the electronic device (101). For example, the advertisement of the electronic device (101) may be executed based on an input (e.g., a user input) made to the cradle exemplified in the description of FIG. 1. For example, the advertisement of the electronic device (101) may be executed based on detecting that the electronic device (101) is being gripped by a user. For example, the advertisement of the electronic device (101) may be executed based on the electronic device (101) obtaining power provided from the cradle.

[0060] As a non-limiting example, a communication link (131) may be established based on an input to a user interface displayed on a display (204) in response to an advertisement of a first external electronic device (111) in response to a signal (or packet) transmitted (or broadcast) (or advertised) from the electronic device (101).

[0061] In operation 402, the first external electronic device (111) may detect an input to search for an audio source device providing a broadcast service (or an audio broadcast service). For example, the input may include an input received by the first external electronic device (111) to output audio of a broadcast service provided from a device surrounding the first external electronic device (111) using the electronic device (101). As a non-limiting example, the input may be detected after a communication link (131) is established. As a non-limiting example, the input may be detected while the communication link (131) is maintained.

[0062] The above input can be implemented in various formats. As a non-limiting example, the input can be implemented as a voice command such as "Find broadcast services provided nearby." As a non-limiting example, the input can be implemented by receiving a signal advertised from another electronic device that has a history of providing broadcast services to the first external electronic device (111) and the electronic device (101). As a non-limiting example, the input can be implemented by changing the state of the communication circuit (302) from an inactive state to an active state. As a non-limiting example, the input can be implemented by receiving a signal from the electronic device (101) requesting synchronization with a broadcast isochronous stream (BIS) upon desynchronization with the BIS. As a non-limiting example, the input can be implemented by establishing a communication link (131). As a non-limiting example, the input may be implemented by confirming that a condition of a routine set according to a user input within the first external electronic device (111) is satisfied. As a non-limiting example, the input may be implemented as a touch input on the display (204) received in connection with a software application that provides a function for searching (or browsing) a broadcast service. The input implemented as a touch input on the display (204) is exemplified within the description of FIG. 5.

[0063] Figure 5 illustrates an example of an input to search for an audio source device providing a broadcast service.

[0064] Referring to FIG. 5, the input may be implemented as a touch input (510) for an executable object (or icon) (or visual object) corresponding to a software application for a broadcast service, such as a state (500). As a non-limiting example, the touch input (510) may be received to initiate execution of the software application. As a non-limiting example, the touch input (510) may be received to change the execution state of the software application. For example, the touch input (510) may be received to change the execution state from a background execution state to a foreground execution state. For example, the background execution state may represent a state in which the software application is executed while a user interface (e.g., user interface (560)) provided from the software application is not displayed using the display (204). For example, the foreground execution state may represent a state in which the software application is executed while at least partially displaying the user interface provided from the software application using the display (204). For example, the background execution state may indicate an execution state of the software application that may be unnoticeable to the user. For example, the foreground execution state may indicate an execution state of the software application that may be noticeable to the user. Although the above descriptions describe the software application as a software application for broadcasting services, this is merely exemplary. For example, the software application may be a software application used to access another electronic device distinct from the first external electronic device (111).For example, the software application may be a software application used to support connection-based communication with the other electronic device and non-connection-based communication with the other electronic device.

[0065] For example, the input may be implemented as an input (or touch input) that causes the first external electronic device (111) to display a user interface (560) using the display (204), such as state (550). For example, the user interface (560) may be displayed to search for (or view) a broadcast service occurring in the user's vicinity, as indicated by text (565). For example, the user interface (560) may include a list (570) of audio source devices that provide a broadcast service that outputs audio. As a non-limiting example, the list (570) may include information about one or more external electronic devices discovered according to a scan performed by the first external electronic device (111). For example, the one or more external electronic devices may have been discovered by the first external electronic device (111) (and / or the electronic device (101)) before the input was detected. For example, the information may include a past search history. For example, the one or more external electronic devices may be searched according to a scan executed by the first external electronic device (111) in response to a touch input (510). For example, the one or more external electronic devices may be searched according to a scan executed by the first external electronic device (111) in response to an event (or input) that causes the display of the user interface (560). However, the present invention is not limited thereto.

[0066] Referring back to FIG. 4, at operation 403, the first external electronic device (111) may perform a first scan for advertisements occurring around the first external electronic device (111) based on the detection of the input. For example, since the first external electronic device (111) is a device that assists the electronic device (101) in operating as an audio sync device for a broadcast service (or an audio broadcast service), the first external electronic device (111) may perform the first scan in response to the detection. For example, the first external electronic device (111) may perform the first scan to transmit information about a periodic advertisement to the electronic device (101) via the communication link (131) in relation to the broadcast service to be provided through the electronic device (101).

[0067] For example, the first scan may be executed to search for audio source devices located around the first external electronic device (111). For example, the audio source device (e.g., the second external electronic device (112) of FIG. 1) may execute one or more advertisements (e.g., one or more advertisements (141) of FIG. 1). For example, the one or more advertisements may include advertising at least one first packet (e.g., an ADV_EXT_IND packet) on each of the primary advertising channels (e.g., Ch. 37, Ch. 38, and Ch. 39). For example, the at least one first packet may indicate that it provides additional data via another (or additional) advertisement (e.g., an extended advertisement). For example, the at least one first packet may indicate at least one second packet (e.g., an AUX_ADV_IND packet) (or an extended advertisement packet). For example, the first scan executed by the first external electronic device (111) may include receiving the at least one first packet.

[0068] For example, the one or more advertisements may include advertising the at least one second packet according to an extended advertisement indicated by the at least one first packet. For example, the first external electronic device (111) may receive, based on the at least one first packet received from the audio source device, at least one second packet advertised on some of the secondary advertising channels different from the primary advertising channels from the audio source device, and indicating a periodic advertisement (e.g., the periodic advertisement (142) of FIG. 1). For example, the first external electronic device (111) may obtain, based on the at least one second packet, the information about the periodic advertisement (e.g., LL(logical link)_PERIODIC_SYNC_IND). For example, the first scan executed by the first external electronic device (111) may include receiving the at least one second packet. For example, the first scan executed by the first external electronic device (111) may include obtaining the information about the periodic advertisement using the at least one second packet.

[0069] For example, the audio source device may execute the periodic advertisement, which is indicated by the at least one second packet. For example, the audio source device may execute the periodic advertisement by advertising at least one packet. For example, the at least one packet may include information about an interval of the periodic advertisement of the audio source device, information about an offset of a transmission according to the periodic advertisement of the audio source device, information about a channel map of the periodic advertisement of the audio source device, information about an ACL, information about an initial value of a cyclic redundancy check (CRC), information about a counter of an event of the periodic advertisement of the audio source device (e.g., PeriodicEventCounter), and information (or advertisement data) about a broadcast isochronous group (BIG) scheduled (or generated) (or acquired) by the audio source device (e.g., including multiple instances for a BIS from the audio source device). For example, the periodic advertisement may be used for synchronization to a BIS from the audio source device. For example, the first external electronic device (111) may receive the at least one packet. For example, the first scan executed by the first external electronic device (111) may include receiving the at least one packet advertised from the audio source device according to the periodic advertisement. For example, the first scan executed by the first external electronic device (111) may include obtaining information about a broadcast service provided from the audio source device using the at least one packet.

[0070] In operation 404, the first external electronic device (111) may transmit a signal to the electronic device (101) that causes the electronic device (101) to perform a second scan for advertisements generated in the vicinity of the electronic device (101) based on the detection of the input. For example, the signal may be transmitted to the electronic device (101) via a communication link (131).

[0071] The signal may be implemented in various ways. For example, the signal may be transmitted to the electronic device (101) via a communication link (131) to indicate that the first external electronic device (111) has initiated a scan (e.g., the first scan) in relation to a broadcast service (or audio broadcast service). As a non-limiting example, the signal may be transmitted via a remote scan started operation of a broadcast audio scan service (BASS).

[0072] The electronic device (101) may receive the signal from the first external electronic device (111) via the communication link (131). For example, the electronic device (101) may use the signal to recognize that the first scan is being performed (or is being performed) by the first external electronic device (111). For example, the electronic device (101) may recognize that performing the second scan is scheduled (or requested) based on the reception (and / or recognition) of the signal. As a non-limiting example, if the signal does not explicitly indicate a request to perform the second scan, the electronic device (101) may be pre-configured to perform the second scan, as in operation 405, in response to receiving the signal.

[0073] Although FIG. 4 illustrates executing operation 404 after executing operation 403, this is merely exemplary. For example, the first external electronic device (111) may execute operation 403 after executing operation 404 in response to the detection. For example, the first external electronic device (111) may execute operations 403 and 404 simultaneously. For example, operations 403 and 404 may be executed under the condition of executing operation 402.

[0074] In operation 405, the electronic device (101) may execute the second scan based on the signal received in operation 404.

[0075] For example, the second scan may be executed to search for an audio source device located around the electronic device (101). For example, the audio source device (which may be the same as or different from the audio source device located around the first external electronic device (111), e.g., the second external electronic device (112) of FIG. 1) may execute one or more advertisements (e.g., one or more advertisements (141) of FIG. 1). For example, the one or more advertisements may include advertising at least one first packet (e.g., an ADV_EXT_IND packet) on each of the primary advertising channels (e.g., Ch. 37, Ch. 38, and Ch. 39). For example, the at least one first packet may indicate that additional data is provided via another (or additional) advertisement (e.g., an extended advertisement). For example, the at least one first packet may indicate at least one second packet (e.g., an AUX_ADV_IND packet) (or an extended advertisement packet). For example, the second scan executed by the electronic device (101) may include receiving the at least one first packet.

[0076] For example, the one or more advertisements may include advertising the at least one second packet according to an extended advertisement indicated by the at least one first packet. For example, the electronic device (101) may receive, based on the at least one first packet received from the audio source device, at least one second packet advertised on some of the secondary advertising channels different from the primary advertising channels from the audio source device, and indicating a periodic advertisement (e.g., the periodic advertisement (142) of FIG. 1). For example, the electronic device (101) may obtain, based on the at least one second packet, the information about the periodic advertisement (e.g., LL(logical link)_PERIODIC_SYNC_IND). For example, the second scan executed by the electronic device (101) may include receiving the at least one second packet. For example, the second scan executed by the electronic device (101) may include obtaining the information about the periodic advertisement using the at least one second packet.

[0077] For example, the audio source device may execute the periodic advertisement, which is indicated by the at least one second packet. For example, the audio source device may execute the periodic advertisement by advertising at least one packet. For example, the at least one packet may include information about an interval of the periodic advertisement of the audio source device, information about an offset of a transmission according to the periodic advertisement of the audio source device, information about a channel map of the periodic advertisement of the audio source device, information about an ACL, information about an initial value of a cyclic redundancy check (CRC), information about a counter of an event of the periodic advertisement of the audio source device (e.g., PeriodicEventCounter), and information (or advertisement data) about a broadcast isochronous group (BIG) scheduled (or generated) (or acquired) by the audio source device (e.g., including multiple instances for a BIS from the audio source device). For example, the periodic advertisement may be used for synchronization to a BIS from the audio source device. For example, the electronic device (101) may receive the at least one packet. For example, the second scan executed by the electronic device (101) may include receiving the at least one packet advertised from the audio source device according to the periodic advertisement. For example, the second scan executed by the electronic device (101) may include obtaining information about a broadcast service provided from the audio source device using the at least one packet.

[0078] As a non-limiting example, the electronic device (101) may synchronize with the BIS from one of the one or more audio source devices discovered based on the results of the second scan. For example, since the synchronization with the BIS is performed before a user input for selecting the audio source device is received by the first external electronic device (111), the electronic device (101) may postpone, bypass, refrain from, disable, or skip outputting audio based on the synchronization with the BIS. Postponing the output of audio based on the synchronization with the BIS is exemplified within the description of FIG. 6.

[0079] FIG. 6 illustrates an example of a method of an electronic device for delaying audio output after synchronization to a broadcast isochronous stream (BIS).

[0080] Referring to FIG. 6, in operation 601, the electronic device (101) may synchronize with periodic advertisements generated around the electronic device (101) for the second scan. For example, synchronizing with the periodic advertisement may indicate receiving at least one packet advertised from an audio source device according to the periodic advertisement (e.g., the at least one packet exemplified in the description of FIG. 4). For example, synchronizing with the periodic advertisement may indicate obtaining information about a BIS from the audio source device advertising the at least one packet.

[0081] In operation 602, the electronic device (101) may synchronize with the BIS according to the synchronization with the periodic advertisement. For example, synchronizing with the BIS may indicate receiving data for the BIS broadcast from the audio source device advertising the at least one packet according to the periodic advertisement.

[0082] For example, if the electronic device (101) is synchronized with a plurality of periodic advertisements according to the second scan, the electronic device (101) may, in operation 602, select, identify, or determine one audio source device from among the plurality of audio source devices that each executed the plurality of periodic advertisements.

[0083] As a non-limiting example, the electronic device (101) may measure the reception strength of each of a plurality of signals (e.g., a plurality of advertising signals or a plurality of advertising packets) received from the plurality of audio source devices according to the second scan, and select an audio source device that advertises a signal having the highest reception strength according to the measurement among the plurality of audio source devices. For example, the electronic device (101) may synchronize with the BIS from the selected audio source device.

[0084] As a non-limiting example, the electronic device (101) may select one of the plurality of audio source devices searched according to the second scan using the usage history. For example, the electronic device (101) may select, from the usage history, the audio source device that broadcasted the signal most recently received by the electronic device (101) (e.g., data for BIS). For example, the electronic device (101) may synchronize with the BIS from the selected audio source device.

[0085] In operation 603, the electronic device (101) may postpone outputting audio in response to synchronization with the BIS. For example, since synchronization with the BIS is performed before a user input for selecting an audio source device that provides audio to be output from the electronic device (101) according to a broadcast service is received by the first external electronic device (111), the electronic device (101) may postpone outputting the audio in response to synchronization with the BIS. As a non-limiting example, since synchronization with the BIS is performed in order to output audio in response to the user input in response to the broadcast service at a fast response speed, the electronic device (101) may postpone outputting the audio in response to synchronization with the BIS.

[0086] Delaying audio output in response to synchronization with the BIS can be implemented in various ways. For example, the electronic device (101) can delay audio output by disabling (or refraining from) (or not executing) rendering data for the BIS received in response to the synchronization with the BIS. For example, the electronic device (101) can activate (or execute) rendering data for the BIS received in response to the synchronization with the BIS, but can delay audio output by controlling the speaker (303) to operate in mute mode. For example, the electronic device (101) can activate rendering data for the BIS received in response to the synchronization with the BIS, but can delay audio output by setting the volume of audio output using the rendered data to a minimum volume (e.g., 0).

[0087] For example, outputting the audio may be interrupted in response to operation 1402 of FIG. 14, which will be illustrated below.

[0088] Referring again to FIG. 4, at operation 406, the electronic device (101) may transmit information about the results of the second scan to the first external electronic device (111). For example, the information may be transmitted to the first external electronic device (111) via a communication link (131).

[0089] For example, the information may include data obtained (or recognized) (or identified) from the one or more advertisements according to the second scan. For example, the information may include data about an audio source device discovered according to the second scan (e.g., a name of the audio source device, a type of the audio source device), data about a broadcast service provided from the audio source device discovered according to the second scan (e.g., information about the broadcast service (or program information of the broadcast service)), and / or data about a BIS from the audio source device discovered according to the second scan. As a non-limiting example, the information may be transmitted via a broadcast receive state of a BASS (or a characteristic behavior of a broadcast receive state).

[0090] The conditions used within the electronic device (101) to transmit the above information may be variously defined or set. For example, the electronic device (101) may transmit the information after executing the second scan for a reference time (or a predetermined time) (or a specified time) (or a designated time). For example, the electronic device (101) may transmit the information on the condition that the second scan is completed for one audio source device. For example, the electronic device (101) may transmit the information based on the number of one or more audio source devices discovered according to the second scan reaching a reference number. For example, the electronic device (101) may transmit the information based on receiving a request (not shown in FIG. 4) to transmit the information from the first external electronic device (111).

[0091] The data included in the above information can be implemented or set in various ways.

[0092] For example, the information may include data related to an audio source device that advertised a signal (e.g., an advertising signal or an advertising packet) having a reception strength exceeding a reference strength. For example, the electronic device (101) may configure (or set) data acquired from at least one signal having a reception strength (e.g., a received signal strength indicator (RSSI)) exceeding a reference strength among the signals received by the electronic device (101) according to the second scan as the information, and transmit the configured information. As a non-limiting example, signals remaining except for the at least one signal among the signals may be discarded.

[0093] For example, the information may include data related to N audio source devices (where N is a natural number greater than or equal to 1), which is a reference number (or a predetermined number). For example, the electronic device (101) may obtain the information including data about audio source devices that have advertised the top N signals with high reception strengths (signals received according to the second scan), and transmit the obtained information.

[0094] The first external electronic device (111) can receive the above information from the electronic device (101) via a communication link (131).

[0095] In operation 407, the first external electronic device (111) may provide feedback according to the input detected in operation 402 using the result of the first scan executed by the first external electronic device (111) and the result of the second scan executed by the electronic device (101).

[0096] The above feedback can be implemented in various ways. For example, the feedback can be implemented by causing the electronic device (101) to synchronize with the BIS from one of the audio source devices discovered based on the results of the first scan and the second scan. For example, the feedback can be implemented by displaying a list of devices acquired based on the results of the first scan and the second scan using the display (204). The feedback implemented by displaying the list of devices is exemplified in the descriptions of FIGS. 7 to 12.

[0097] Figures 7 to 12 illustrate examples of a device list displayed using a display of a first external electronic device.

[0098] Referring to FIG. 7, the first external electronic device (111) may display a device list (702) obtained according to the results of the first scan and the results of the second scan within the user interface (701) for the broadcast service, using the display (204), as in a state (700). The device list (702) may be configured so that the device that performed the scan (e.g., the electronic device (101) or the first external electronic device (111)) can be distinguished by the user. For example, an area within the device list (702) that displays one or more executable objects each representing one or more audio source devices discovered by the first external electronic device (111) that performed the first scan may be different from an area within the device list (702) that displays one or more executable objects each representing one or more audio source devices discovered by the electronic device (101) that performed the second scan. For example, one or more executable objects (703) each representing one or more audio source devices discovered by the electronic device (101) according to the second scan may be positioned within the device list (702) in association with a visual object (705) (e.g., text (705)) representing the type (or name) of the electronic device (101). For example, each of the one or more executable objects (703) may be used to execute synchronization from the audio source device represented by each of the one or more executable objects (703) to the BIS.

[0099] For example, one or more executable objects (704) each representing one or more audio source devices discovered by the first external electronic device (111) according to the first scan may be positioned within the device list (702) in association with a visual object (706) (e.g., text (706)) representing a type (or name) of the first external electronic device (111). For example, each of the one or more executable objects (704) may be used to execute synchronization from the audio source device represented by each of the one or more executable objects (704) to the BIS.

[0100] Referring to FIG. 8, the first external electronic device (111) may display, as in a state (800), a device list (802) obtained according to the results of the first scan and the second scan within a user interface (801) for a broadcast service using a display (204). The configuration of the device list (802) may be different from the configuration of the device list (702). For example, the device list (802) may include an executable object (803), an executable object (804), and an executable object (805). Each of the executable object (803), the executable object (804), and the executable object (805) may represent an audio source device and / or a broadcast service provided from the audio source device searched according to the results of the first scan or the second scan.

[0101] For example, the executable object (803) may include a visual object (803-1) indicating the intensity of a signal received from the audio source device to the first external electronic device (111) during the first scan, a visual object (803-2) including information about a broadcast service provided from the audio source device, a visual object (803-3) including information about the audio source device, and / or a visual object (803-4) including information about a device (e.g., the first external electronic device (111)) that performed a scan (e.g., the first scan) of the audio source device represented by the executable object (803). For example, the executable object (803) may be used to perform synchronization from the audio source device represented by the executable object (803) to the BIS.

[0102] For example, the executable object (804) may include a visual object (804-1) indicating the strength of a signal received by the electronic device (101) from the audio source device during the second scan, a visual object (804-2) including information about a broadcast service provided from the audio source device, a visual object (804-3) including information about the audio source device, and / or a visual object (804-4) including information about a device (e.g., the electronic device (101)) that performed the scan (e.g., the second scan) of the audio source device represented by the executable object (804). For example, the executable object (804) may be used to perform synchronization from the audio source device represented by the executable object (804) to the BIS.

[0103] For example, the executable object (805) may include a visual object (805-1) indicating the intensity of a signal received from the audio source device to the first external electronic device (111) during the first scan, a visual object (805-2) including information about a broadcast service provided from the audio source device, a visual object (805-3) including information about the audio source device, and / or a visual object (805-4) including information about a device (e.g., the first external electronic device (111)) that performed a scan (e.g., the first scan) of the audio source device represented by the executable object (805). For example, the executable object (805) may be used to perform synchronization from the audio source device represented by the executable object (805) to the BIS.

[0104] For example, each of the executable objects (803), the executable objects (804), and the executable objects (805) may include a visual object (803-4), a visual object (804-4), and a visual object (805-4) that textually represent a device (e.g., an electronic device (101) and / or a first external electronic device (111)) that has discovered an audio source device represented by each of the executable objects (803), the executable objects (804), and the executable objects (805).

[0105] Referring to FIG. 9, the first external electronic device (111) may display a device list (902) obtained according to the results of the first scan and the results of the second scan within a user interface (901) for a broadcast service using a display (204), as in a state (900). For example, the device list (902) may include an executable object (903), an executable object (904), and an executable object (905). For example, each of the executable object (903), the executable object (904), and the executable object (905) may include a visual object (903-4), a visual object (904-4), and a visual object (905-4) that replace the visual object (803-4), the visual object (804-4), and the visual object (805-4) included within the executable object (803), the executable object (804), and the executable object (805), respectively. For example, each of the visual object (903-4), the visual object (904-4), and the visual object (905-4) may graphically represent the shape of a device that has discovered an audio source device represented by each of the executable object (903), the executable object (904), and the executable object (905).

[0106] Referring to FIG. 10, the first external electronic device (111) may, as in a state (1000), use the display (204) to display a device list (1002) obtained according to the results of the first scan and the results of the second scan within a user interface (1001) for a broadcast service. The device list (1002) may include executable objects each representing an audio source device. For example, the arrangement of the executable objects within the device list (1002) may be determined according to the priorities of each of the audio source devices (and / or the broadcast services provided by each of the audio source devices). For example, the size of each of the executable objects within the device list (1002) may be determined according to the priorities of each of the audio source devices (and / or the broadcast services provided by each of the audio source devices).

[0107] For example, the device list (1002) may include an executable object (1003), an executable object (1004), and an executable object (1005). For example, the executable object (1003) representing the audio source device with the highest priority (or the broadcast service with the highest priority) may be closer to the top of the user interface (1001) than the executable object (1004) and the executable object (1005). For example, the size of the executable object (1003) representing the audio source device with the highest priority (or the broadcast service with the highest priority) may be larger than the sizes of each of the executable object (1004) and the executable object (1005).

[0108] For example, the criteria for determining (or identifying) (or defining) the priorities of the audio source devices (and / or the priorities of the audio services provided by the audio source devices) discovered according to the first scan and the second scan can be set in various ways. For example, the priorities can be determined according to the strength of the signals received from each of the audio source devices. For example, the priorities can be determined according to the order in which the signals are received from each of the audio source devices. For example, the priorities can be determined according to whether there is a history in which the signals were received from each of the audio source devices. For example, the priorities can be determined according to whether the device that discovered each of the audio source devices is the electronic device (101) or the first external electronic device (111). However, the present invention is not limited thereto.

[0109] Referring to FIG. 11, the first external electronic device (111) may, as in a state (1100), use the display (204) to display a device list (1102) obtained according to the results of the first scan and the results of the second scan within the user interface (1101) for the broadcast service. One or more executable objects, each representing one or more audio source devices discovered by the electronic device (101) among the executable objects within the device list (1102), may be visually highlighted relative to one or more other executable objects, each representing one or more other audio source devices discovered by the first external electronic device (111) among the executable objects within the device list (1102).

[0110] For example, the device list (1102) may include an executable object (1103) representing an audio source device discovered by the electronic device (101) (or both the electronic device (101) and the first external electronic device (111)), an executable object (1104) representing an audio source device discovered by the first external electronic device (111) among the electronic device (101) and the first external electronic device (111), an executable object (1105) representing an audio source device discovered by the electronic device (101) (or both the electronic device (101) and the first external electronic device (111)), and an executable object (1106) representing an audio source device discovered by the first external electronic device (111) among the electronic device (101) and the first external electronic device (111). For example, executable objects (1103) and executable objects (1105), which respectively represent audio source devices discovered by the electronic device (101), may be visually highlighted relative to executable objects (1104) and executable objects (1106), which respectively represent audio source devices not discovered by the electronic device (101) (or discovered only by the first external electronic device (111). For example, executable objects (1103) and executable objects (1105), unlike executable objects (1104) and executable objects (1106), may have visual effects.

[0111] As a non-limiting example, the order in which executable objects (1103), executable objects (1104), executable objects (1105), and executable objects (1106) are displayed within the device (1102) may be determined based on the priorities exemplified within the description of FIG. 10.

[0112] Referring to FIG. 12, the first external electronic device (111) may display, as in a state (1200), a device list (1202) obtained according to the results of the first scan and the results of the second scan within a user interface (1201) for a broadcast service using a display (204). An executable object having the highest priority among executable objects within the device list (1202) representing each of the audio source devices may include more visual elements than the remaining executable objects within the device list (1202) representing each of the audio source devices.

[0113] For example, the device list (1202) may include an executable object (1203), an executable object (1204), and an executable object (1205). For example, the priority of an audio source device (or broadcast service) represented by an executable object (1203) may be higher than the priority of an audio source device (or broadcast service) represented by an executable object (1204) and the priority of an audio source device (or broadcast service) represented by an executable object (1205). For example, the executable object (1203) may further include a visual element (1206) to indicate an audio source device (or broadcast service) with the highest priority.

[0114] Referring back to FIG. 4, the first external electronic device (111) can assist a broadcast service to be provided using the electronic device (101) by providing the feedback according to the input detected in operation 402, according to operation 407. For example, the first external electronic device (111) can provide the feedback by displaying a device list. For example, the first external electronic device (111) can obtain first data on the received signal strength measured by the first external electronic device (111) according to the first scan, and can obtain second data on the received signal strength measured by the electronic device (101) according to the second scan from the information received from the electronic device (101) (e.g., the information in operation 406). For example, the first external electronic device (111) can obtain the device list using the first data and the second data, and display the device list as shown in FIGS. 7 to 12.

[0115] For example, since the methods described in the description of FIG. 4 and the description of FIGS. 5 to 12 in conjunction with the description of FIG. 4 include scanning of the electronic device (101) (e.g., operation 405 of FIG. 4)) as well as scanning of the first external electronic device (111), the electronic device (101) and the first external electronic device (111) can provide a search for a broadcast service having diversity. For example, since the broadcast service is provided by the electronic device (101) synchronizing with the BIS from the audio source device, the scanning of the electronic device (101) can be more suitable for the wireless environment for the broadcast service than the scanning of the first external electronic device (111). For example, the methods can provide an enhanced broadcast service.

[0116] As described above, the first external electronic device (111) may receive a user input to search for an audio source device, and, based on the user input, transmit a signal to cause the audio sink device to perform a scan for advertisements from audio source devices located around (or close to) the audio sink device, receive information regarding a result of the scan performed by the audio sink device, and, based on the result of the scan performed by the audio sink device, designate a device discovered according to the scan as an audio source device, and transmit a request to the audio sink device to synchronize to a broadcast isochronous stream (BIS) from the audio source device.

[0117] For example, the first external electronic device (111) may receive user input after providing the feedback according to operation 407. As a non-limiting example, the user input may be received to select a broadcast service from among the audio source devices (or broadcast services) indicated through the device list exemplified above. An operation according to the user input is exemplified within the description of FIG. 13.

[0118] FIG. 13 illustrates an example of a method of a first external electronic device executing in response to user input received for a device list.

[0119] Referring to FIG. 13, in operation 1301, the first external electronic device (111) may receive a user input while displaying a device list (e.g., one of the device lists illustrated in FIGS. 7 to 12 ) with the feedback according to operation 407. For example, the user input may include a touch input on one of the executable objects (e.g., the executable objects illustrated in FIGS. 7 to 12 ) in the device list, each representing an audio source device discovered according to the first scan and the second scan. For example, the user input may be received to select one of the audio source devices discovered according to the first scan and the second scan.

[0120] In operation 1302, the first external electronic device (111) can determine whether the user input received in operation 1301 is a user input for selecting the external electronic device discovered according to the second scan as an audio source device of a broadcast service to be provided through the electronic device (101) or a user input for selecting another external electronic device not discovered according to the second scan (or discovered only by the first scan) as the audio source device. For example, when the user input indicates the external electronic device discovered according to the second scan (or both the first scan and the second scan), the first external electronic device (111) can execute operation 1303. For example, when the user input indicates the other external electronic device not discovered according to the second scan (or discovered only by the first scan), the first external electronic device (111) can execute operation 1304.

[0121] Action 1302 is included in FIG. 13 to indicate that action 1303 or action 1304 may be executed depending on the user input received in action 1301. Action 1302 may be varied in various ways.

[0122] In operation 1303, the first external electronic device (111) may transmit a request to the electronic device (101) to synchronize with the BIS from the external electronic device, based on receiving a user input in operation 1301 that determines the external electronic device discovered according to the second scan (or discovered according to both the first scan and the second scan) as the audio source device. For example, the first external electronic device (111) may transmit the request because the electronic device (101) performed synchronization with the periodic advertisement of the external electronic device according to the second scan (operation 405 of FIG. 4) performed (or executed) prior to operation 1301. For example, the first external electronic device (111) may transmit the request instead of information about the periodic advertisement of the external electronic device. As a non-limiting example, the request may be transmitted via an add source operation of BASS.

[0123] For example, the electronic device (101) may output audio for a broadcast service based on receiving the request transmitted from the first external electronic device (111) in operation 1303. For example, the electronic device (101) may provide the broadcast service by outputting the audio based on synchronization from the external electronic device to the BIS after the request is received. As a non-limiting example, the synchronization from the external electronic device to the BIS may be executed before the request is transmitted from the first external electronic device (111) in operation 1303, as exemplified in the description of FIG. 6. Outputting audio according to the synchronization to the BIS executed before the request is transmitted from the first external electronic device (111) in operation 1303 will be exemplified in the description of FIG. 14.

[0124] In operation 1304, the first external electronic device (111) may transmit information about periodic advertisements of the other external electronic device to the electronic device (101) via the communication link (131) based on receiving a user input in operation 1301 that determines the other external electronic device, which is not discovered by the second scan but is discovered by the first scan among the first and second scans, as the audio source device. For example, since the other external electronic device is a device that is not discovered by the second scan executed by the electronic device (101), the first external electronic device (111) may transmit the information about periodic advertisements of the other external electronic device. For example, the information about the periodic advertisement of the other external electronic device may indicate an interval of the periodic advertisement of the other external electronic device, a hopping sequence of the periodic advertisement of the other external electronic device, and / or an access address for synchronizing with the BIS from the other external electronic device. As a non-limiting example, the information may be transmitted via an additional source operation of the BASS.

[0125] For example, the electronic device (101) may synchronize with the periodic advertisement of the other external electronic device based on receiving the information transmitted from the first external electronic device (111) in operation 1304. For example, the electronic device (101) may synchronize with the BIS from the other external electronic device based on the synchronization with the periodic advertisement of the other external electronic device. For example, the electronic device (101) may provide a broadcast service by outputting audio based on the synchronization with the BIS from the other external electronic device.

[0126] As described above, and as a non-limiting example, the electronic device (101) may synchronize with the BIS from an audio source device (e.g., the external electronic device in the description of FIG. 13) before operation 1303 is executed to provide a fast response speed for a broadcast service (e.g., operation 602). For example, the electronic device (101) may maintain the synchronization from the audio source device to the BIS until the request transmitted from the first external electronic device (111) in operation 1303 is received. For example, the electronic device (101) may receive the request from the first external electronic device (111) while maintaining the synchronization from the audio source device to the BIS. An operation according to the request received while maintaining the synchronization from the audio source device to the BIS is exemplified in the description of FIG. 14.

[0127] FIG. 14 illustrates an example of a method of an electronic device that, upon receipt of a request, initiates output of delayed audio after synchronization to a broadcast isochronous stream (BIS).

[0128] Referring to FIG. 14, in operation 1401, the electronic device (101) may delay outputting audio based on synchronization from the audio source device to the BIS. For example, operation 1401 may correspond to operation 603 of FIG. 6.

[0129] In operation 1402, the electronic device (101) may receive the request transmitted from the first external electronic device (111) in operation 1303 of FIG. 13.

[0130] In operation 1403, the electronic device (101) may output audio according to the synchronization from the audio source device to the BIS maintained before the request is received, based on confirming (or determining) that the request relates to the audio source device that provides the BIS synchronized by the electronic device (101). For example, the electronic device (101) may output the audio by activating (or executing) rendering data for the BIS received according to the synchronization to the BIS, based on the reception of the request. For example, the electronic device (101) may output the audio by controlling the speaker (303) to unmute, based on the reception of the request. For example, the electronic device (101) may output the audio by changing the volume of the audio output using the rendered data to a volume according to a system setting, based on the reception of the request.

[0131] As described above, the electronic device (101) can provide a broadcast service at a fast response speed by utilizing the synchronization with the BIS executed before the request is received.

[0132] The operations of the electronic device (101) and the first external electronic device (111) exemplified above can be executed by the electronic device (1501) and the electronic device (1502) exemplified in the description of FIG. 15.

[0133] FIG. 15 is a block diagram of an electronic device (1501) within a network environment (1500) according to various embodiments. Referring to FIG. 15 , in the network environment (1500), the electronic device (1501) may communicate with the electronic device (1502) via a first network (1598) (e.g., a short-range wireless communication network), or may communicate with at least one of the electronic device (1504) or the server (1508) via a second network (1599) (e.g., a long-range wireless communication network). In one embodiment, the electronic device (1501) may communicate with the electronic device (1504) via the server (1508). According to one embodiment, the electronic device (1501) may include a processor (1520), a memory (1530), an input module (1550), an audio output module (1555), a display module (1560), an audio module (1570), a sensor module (1576), an interface (1577), a connection terminal (1578), a haptic module (1579), a camera module (1580), a power management module (1588), a battery (1589), a communication module (1590), a subscriber identification module (1596), or an antenna module (1597).

[0134] The processor (1520) may, for example, execute software (e.g., a program (1540)) to control at least one other component (e.g., a hardware or software component) of the electronic device (1501) connected to the processor (1520) and perform various data processing or operations.

For example, when the electronic device (1501) includes the main processor (1521) and the auxiliary processor (1523), the auxiliary processor (1523) may be configured to use less power than the main processor (1521) or to be specialized for a given function.

[0135] The auxiliary processor (1523) may control at least a portion of functions or states associated with at least one component (e.g., the display module (1560), the sensor module (1576), or the communication module (1590)) of the electronic device (1501), for example, on behalf of the main processor (1521) while the main processor (1521) is in an inactive (e.g., sleep) state, or together with the main processor (1521) while the main processor (1521) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (1523) (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 (1580) or a communication module (1590)). In one embodiment, the auxiliary processor (1523) (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, on the electronic device (1501) where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (1508)).

According to one embodiment, the audio module (1570) can acquire sound through the input module (1550), output sound through the sound output module (1555), or an external electronic device (e.g., electronic device (1502)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (1501).

[0142] The sensor module (1576) can detect the operating status (e.g., power or temperature) of the electronic device (1501) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status.

The communication module (1590) may operate independently from the processor (1520) (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 (1590) may include a wireless communication module (1592) (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 (1594) (e.g., a local area network (LAN) communication module, or a power line communication module). Any of these communication modules may communicate with an external electronic device (1504) via a first network (1598) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (1599) (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 local area network or a wide area network)). These various types of communication modules may 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 (1592) may use subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (1596) to verify or authenticate the electronic device (1501) within a communication network such as the first network (1598) or the second network (1599).

[0150] The wireless communication module (1592) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimizing terminal power and connecting multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency communications (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (1592) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (1592) may support various technologies for securing performance in high-frequency bands, 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 (1592) may support various requirements specified in the electronic device (1501), an external electronic device (e.g., the electronic device (1504)), or a network system (e.g., the second network (1599)).

[0151] The antenna module (1597) 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 (1597) 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 (1597) 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 (1598) or the second network (1599), may be selected from the plurality of antennas by, for example, the communication module (1590). A signal or power may be transmitted or received between the communication module (1590) and the external electronic device via the at least one selected 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 (1597).

[0152] According to various embodiments, the antenna module (1597) 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.

[0153] 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)).

[0154] According to one embodiment, commands or data may be transmitted or received between the electronic device (1501) and an external electronic device (1504) via a server (1508) connected to a second network (1599). Each of the external electronic devices (1502 or 1504) may be the same or a different type of device as the electronic device (1501). According to one embodiment, all or part of the operations executed in the electronic device (1501) may be executed in one or more of the external electronic devices (1502, 1504, or 1508). For example, when the electronic device (1501) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (1501) 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 a 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 (1501). The electronic device (1501) 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 (1501) may provide an ultra-low latency service using, for example, distributed computing or mobile edge computing. In another embodiment, the external electronic device (1504) may include an Internet of Things (IoT) device. The server (1508) may be an intelligent server utilizing machine learning and / or a neural network.According to one embodiment, an external electronic device (1504) or server (1508) may be included within the second network (1599).
