For example, the communication circuit 590 may further include more receive paths than that shown in FIG. 5. For another example, the communication circuit 590 may include at least one transmission path. At least one transmission path may be selectively connected to the antenna 560. The structure of the communication circuit 590 of FIG. 5 is exemplary, and embodiments of the present document are not limited thereto. For example, the first reception path 580 may be connected to the antenna 560 and the second reception path 585 may be connected to a separate antenna (not shown). In this case, the switching circuit 591 may be omitted. The processor 520 may receive data from an external electronic device through the first receiving path 580 or the second receiving path 585 without using the switching circuit 591. For example, the processor 520 may receive data from an external electronic device by selectively using a first reception path 580 or a second reception path 585 connected to different antennas.

For example, the antenna 560 may have a resonance frequency characteristic corresponding to a frequency of a designated band. The communication circuit 590 may receive a signal of a designated band through the antenna 560. The processor 520 may receive a signal of a designated band through the antenna 560 using the communication circuit 590.

According to an embodiment, the memory 530 is operatively connected to the processor 520 and may store one or more instructions that cause the processor 520 to perform various functions or operations when executed. The memory 530 may include a buffer 535 (eg, a fill-in buffer). For example, the processor 520 may receive data from an external electronic device using the communication circuit 580 and store the received data in the buffer 535. 5 illustrates that the buffer 535 is included in the memory 530, embodiments of the present document are not limited thereto. The buffer 535 may be implemented as a memory separate from the memory 530. For example, the buffer 535 may be included in the processor 520 or the communication circuit 590.

According to an embodiment, the processor 520 may receive data from an external electronic device and store the received data in the buffer 535. For example, the processor 520 may buffer data received from an external electronic device. The processor 520 may output media by using data stored in the buffer 535. For example, the output circuit 570 may be an audio output circuit (eg, a speaker). The processor 520 may output an audio signal using the output circuit 570 based on data stored in the buffer 535. The processor 520 may output media by sequentially using data stored in the buffer 535. For example, the processor 520 may sequentially output data stored in the buffer 535 in a first in-first out (FIFO) method. For example, when the amount of data stored in the buffer 535 is greater than or equal to a specified amount during communication with an external electronic device, the processor 520 sequentially outputs the data by using the data stored in the buffer 535 in sequence. , Data used for output or output data may be deleted from the buffer 535 or excluded from data to be output. The remaining data remaining in the buffer 535 may mean data remaining in the buffer 535 except for data that has already been output.

According to various embodiments, the processor 520 receives a signal from an external electronic device using the first reception path 580 or the second reception path 585 based on a communication environment associated with the electronic device 501. can do. The processor 520 may select the first reception path 580 or the second reception path 585 based on the communication environment, and may receive data from an external electronic device using the selected reception path. For example, the processor 520 may connect the antenna 560 to the first receiving path 580 or the second receiving path 585 using the communication circuit 590. For example, the processor 520 may receive a signal from an external electronic device through the first receiving path 580 or the second receiving path 585 according to a communication environment associated with the electronic device 501. For example, the processor 520 may determine the amount of remaining data, the received signal strength, the error rate, the channel assessment, the operation state of other communication circuits (eg, the WiFi communication module 595), multiple connections, the retransmission rate, It can be identified based on at least one of a response signal, synchronization, and/or data error. For example, when the communication environment is bad, the processor 520 connects the antenna 560 to the second reception path 585 using the communication circuit 590, and external electronic devices through the second reception path 585 It can receive signals from the device. By receiving the signal through the second receiving path 585, the processor 520 may improve the quality of the received signal. For another example, when the communication environment is good, the processor 520 connects the antenna 560 to the first receiving path 580 using the communication circuit 590, and externally through the first receiving path 580. A signal can be received from an electronic device. By receiving a signal through the first receiving path 580, the processor 520 may reduce current consumption.

According to an embodiment, the processor 520 may select the first receiving path 580 or the second receiving path 585 based on the amount of remaining data. For example, when the processor 520 outputs media by using the data of the buffer 535, the storage speed of the data to the buffer 535 may be lower than the output speed of the data. For example, when the communication environment of the electronic device 501 is not good, the data storage speed in the buffer 535 may decrease as the data reception speed from the external electronic device decreases. In this case, as time passes, the amount of data remaining in the buffer 535 may decrease. According to an embodiment, if the amount of residual data is less than the first threshold value, the processor 520 may receive a signal from an external electronic device through the second reception path 585. For example, while the antenna 560 is connected to the second receive path 585, if the amount of residual data is reduced to less than the first threshold, the processor 520 may perform the antenna 560 and the second receive path 585. You can keep the connection. As another example, while the antenna 560 is connected to the first receiving path 580, if the amount of residual data is reduced to less than the first threshold, the processor 520 uses the communication circuit 590 to perform the antenna 560 ) May be connected to the second receiving path 585 and a signal from an external electronic device may be received through the second receiving path 585. As another example, while the antenna 560 is connected to the first reception path 580, if the amount of residual data increases above the second threshold value, the processor 520 performs the antenna 560 and the first reception path ( 580). As another example, while the antenna 560 is connected to the second reception path 585, when the amount of residual data increases above the second threshold, the processor 520 uses the communication circuit 590 to perform the antenna ( The 560 may be connected to the first receiving path 580 and a signal may be received from an external electronic device through the first receiving path 580. For example, the second threshold may be greater than or equal to the first threshold.

According to an embodiment, the processor 520 may set a size and/or a threshold value of the buffer 535 based on the type of data received from an external electronic device. For example, the type of data may be set by an application associated with the data (eg, an application of an external electronic device). The type of data may include data associated with a game application, data associated with an audio playback application, and/or data associated with a call application. For example, the processor 520 may use a buffer 535 having a first size for data related to a game application, and may use a buffer 535 having a second size for data related to an audio playback application. For example, the processor 520 may use a threshold value different from the threshold value for data associated with the audio playback application for data associated with the game application. For example, the processor 520 may use a threshold value set according to the size of the buffer 535. In this case, information indicating the type of corresponding data may be transmitted from the external electronic device to the electronic device 500. For example, when connected to an external electronic device, the electronic device 501 receives information indicating the type of data, information indicating the size of the buffer 535, and/or information indicating a threshold value from the external electronic device. can do. For another example, when the external electronic device and any other electronic device are connected, the external electronic device includes information indicating the type of data to electronic devices (for example, the electronic device 501) connected to the external electronic device, and a buffer ( Information indicating the size of 535) and/or information indicating a threshold value may be transmitted.

According to an embodiment, the processor 520 may select the first receiving path 580 or the second receiving path 585 based on the strength of the received signal. For example, the processor 520 may acquire signal strength information (eg, RSSI (received signal strength indicator)) received from an external electronic device using the communication circuit 590 using the communication circuit 590. have. The processor 520 connects the antenna 560 to the first receiving path 580 using the communication circuit 590 when the strength of the received signal is greater than or equal to the third threshold, and the strength of the received signal is less than the fourth threshold. The rear antenna 560 may be connected to the second reception path 585 using the communication circuit 590. For example, the third threshold may correspond to a received signal strength higher than the fourth threshold.

According to an embodiment, the processor 520 may select the first receiving path 580 or the second receiving path 585 based on the error rate. For example, the error rate may include a bit error rate or a packet error rate. The processor 520 connects the antenna 560 to the second reception path 585 using the communication circuit 590 when the error rate is greater than or equal to the fifth threshold, and the communication circuit 590 when the error rate is less than the sixth threshold value. The antenna 560 may be connected to the first receiving path 580 by using. For example, the fifth threshold may be a value corresponding to an error rate higher than the sixth threshold.

According to an embodiment, the processor 520 may select the first reception path 580 or the second reception path 585 based on channel evaluation. For example, the processor 520 may perform channel evaluation on a plurality of channels using the communication circuit 590. If the number of good channels is equal to or greater than the seventh threshold by channel evaluation, the processor 520 may connect the antenna 560 to the first reception path 580 using the communication circuit 590. If the number of good channels is less than the eighth threshold, the processor 520 may connect the antenna 560 to the second receive path 585 using the communication circuit 590. For example, the seventh threshold may be a number greater than the eighth threshold.

According to an embodiment, the processor 520 may select the first receiving path 580 or the second receiving path 585 based on an operating state of another communication circuit. For example, when the Wi-Fi communication module 595 is in operation (for example, the Wi-Fi communication module 595 is activated or a signal is transmitted/received), the processor 520 operates the communication circuit 590. By using the antenna 560 can be connected to the second receiving path 585. When the Wi-Fi communication module 595 is not in operation, the processor 520 may connect the antenna 560 to the first reception path 580 using the communication circuit 590.

According to an embodiment, the processor 520 may select the first receiving path 580 or the second receiving path 585 based on multiple connections. For example, when the communication circuit 590 is simultaneously connected to multiple links, the processor 520 may connect the antenna 560 to the second reception path 585 using the communication circuit 590. When the communication circuit 590 is connected to only one link, the processor 520 may connect the antenna 560 to the first reception path 580 using the communication circuit 590.

According to an embodiment, the processor 520 may select the first receiving path 580 or the second receiving path 585 based on the retransmission rate. For example, the processor 520 receives the second antenna 560 using the communication circuit 590 when the retransmission rate (eg, the retransmission rate of the external electronic device or the electronic device 501) is greater than or equal to the ninth threshold. Can connect to path 585. When the retransmission rate is less than the tenth threshold, the processor 520 may connect the antenna 560 to the first reception path 580 using the communication circuit 590. For example, the ninth threshold may correspond to a retransmission rate higher than the tenth threshold.

According to an embodiment, the processor 520 may select the first receiving path 580 or the second receiving path 585 based on the response signal. For example, if the ratio of the negative acknowledgment (NACK) from the external electronic device or the ratio of the NACK of the electronic device 501 is less than the eleventh threshold, the processor 520 uses the communication circuit 590 to the antenna 560 Is connected to the first reception path 580, and when the twelfth threshold value is higher, the antenna 560 may be connected to the second reception path 585 using the communication circuit 590. For example, the 11th threshold may correspond to a NACK rate lower than the 12th threshold. For another example, the processor 520 may use the communication circuit 590 to connect the antenna 560 to the second receiving path 585 when the ACK missing rate from the external electronic device is greater than or equal to the thirteenth threshold. If it is connected and is less than the 14th threshold, the antenna 560 may be connected to the first reception path 580 using the communication circuit 590. For example, the thirteenth threshold may correspond to a higher ACK drop rate than the 14th threshold.

According to an embodiment, the processor 520 may select the first receiving path 580 or the second receiving path 585 based on synchronization. The processor 520 may activate the communication circuit 590 to receive a signal for synchronization (eg, a signal including a polling packet) from an external electronic device (eg, a master device). At this time, if the processor 520 fails to receive a signal for synchronization from an external electronic device (for example, when a signal is not received or when the signal has failed to be decoded), the processor 520 performs a synchronization timeout (sync timeout). ) Can be determined. For example, if the frequency or ratio of the sync timeout with the external electronic device is greater than or equal to the fifteenth threshold, the processor 520 transmits the antenna 560 to the second receiving path 585 using the communication circuit 590. ), and if it is less than the 16th threshold, the antenna 560 may be connected to the first reception path 580 using the communication circuit 590. For example, the fifteenth threshold may correspond to a synchronization timeout frequency greater than the sixteenth threshold or a high synchronization timeout ratio.

According to an embodiment, the processor 520 may select the first receiving path 580 or the second receiving path 585 based on a data error. For example, if a header error, a cyclic redundancy check (CRC) error, and/or a payload missing of the received data is greater than or equal to a specified 17th threshold, the processor 520 uses the communication circuit 590 to If 560 is connected to the second reception path 585 and less than the 18th threshold, the antenna 560 may be connected to the first reception path 580 using the communication circuit 590. For example, the 17th threshold may correspond to an error rate higher than the 18th threshold.

According to various embodiments, the processor 520 may select the first reception path 580 or the second reception path 585 based on a combination of a plurality of criteria among the criteria related to the above-described communication state. For example, the processor 520 may determine whether a reception path change is required based on the amount of remaining data. If a change in the receive path is required, the processor 520 may use the remaining criteria (e.g., received signal strength, error rate, channel evaluation, operation status of other communication circuits, multiple connections, retransmission rate, response signal, synchronization, and/or Error) may be further considered to determine whether to change the reception path. For example, if the amount of remaining data indicates that it is not necessary to change the reception path currently connected to the antenna 560, the processor 520 may maintain the currently connected reception path. When the amount of residual data indicates that the reception path currently connected to the antenna 560 needs to be changed, the processor 520 may determine the change of the reception path based on at least one of the remaining criteria.

For example, the electronic device 501 may be a device that receives sound source data from a source device (eg, the first device 202-1 or the second device 202-2 of FIG. 2 ). The electronic device 501 may set the size of the buffer 535 to a size corresponding to 500 ms. The electronic device 501 may receive sound source data from the external electronic device every about 20 ms, and when the amount of data stored in the buffer 535 is greater than or equal to a specified value, the electronic device 501 may output the sound source using the buffered data. For example, when starting to output a sound source, the antenna 560 may be connected to the first path 580. After starting the output of the sound source, if the amount of residual data in the buffer 535 falls below a size corresponding to 75 ms, the electronic device 501 uses the communication circuit 590 to connect the antenna 560 to the second receiving path. Can be connected to (585). The electronic device 501 may increase reception sensitivity and prevent sound interruption by using the second reception path 585. After connecting the second reception path 585 and the antenna 560, when the amount of remaining data increases to 400 ms or more, the electronic device 501 first receives the antenna 560 using the communication circuit 590. Can connect to path 580. The electronic device 501 may reduce power consumption by using the first reception path 580. In the examples of FIG. 5, it is disclosed that the processor 520 determines to change the reception path, but at least some of the decisions of the processor 520 may be performed by the communication circuit 590.

In response to receiving the request to change the reception path, the communication circuit 590 may change the reception path connected to the antenna 560 using the switch circuit 591 based on the communication environment. In this case, the communication circuit 590 may determine whether to change the reception path based on the communication environment. For another example, the change of the reception path may be performed by the communication circuit 590. In this case, the processor 520 transmits information necessary for changing a reception path (eg, information on a communication environment) to the communication circuit 590, and the communication circuit 590 uses the information received from the processor 520. You can select the destination path. For example, the processor 520 transmits information about the state of the memory (eg, buffer state information) to the communication circuit 590, and the communication circuit 590 establishes a reception path based on the information about the state of the memory. You can choose.

In the examples of FIG. 5, methods of changing a reception path according to various criteria have been described, but embodiments of the present document are not limited thereto. According to an embodiment, the embodiments of FIG. 5 may determine whether to change a reception path based on a data type of received data (eg, a data type according to an application related to data). For example, the electronic device 501 is set to use a designated receiving path (eg, a first receiving path 580 or a second receiving path 585) for a designated type of received data, and changing the receiving path. It may not be done. For example, the electronic device 501 may use the second reception path 585 for game-related data, and may select a reception path for data related to voice reproduction according to at least one of the above-described embodiments. .

In the examples of FIG. 5, methods of changing a reception path according to various criteria have been described, but embodiments of the present document are not limited thereto. According to an embodiment, the electronic device 501 may determine a method of changing a reception path according to a profile associated with the received data. For example, when the profile related to the received data is a profile related to music reproduction (eg, an advanced audio distribution profile), the electronic device 501 may select a receiving path according to at least one of the above-described embodiments. For another example, if the profile associated with the received data is a profile associated with a voice call (for example, synchronous connection oriented (SCO) or enhanced SCO), the electronic device 501 does not receive data from an external electronic device within a specified time period. Otherwise, if data reception fails, data reception may be attempted using the second reception path 585. For example, the designated time period may be a time period set between the external electronic device and the electronic device 501 in relation to data reception.

In the examples of FIG. 5, the change of the reception path according to various criteria may be performed based on a combination of two or more methods. For example, the change of the reception path may be determined based on the priority or weight of two or more criteria.

And, if the amount of residual data is less than or equal to the first threshold value 610, the antenna 560 may be connected to the second reception path 584 using the switch circuit 591.

For example, when the antenna and the first reception path are already connected, in operation 810, the processor may maintain the reception path of the antenna as the first reception path.
