Electronic device and method for synchronization with another electronic device in wireless environment

A first electronic device comprising:

• a microphone;
• a communication circuit;
• at least one processor comprising processing circuitry;
• and
• memory, comprising one or more storage mediums, storing instructions that, when executed by the at least one processor individually and/or collectively, cause the first electronic device to:
• identify a request of a broadcast service to provide, based on synchronizing a second audio signal obtained via a microphone of a second electronic device with a first audio signal obtained via the microphone of the first electronic device, the first audio signal and the second audio signal to at least one external electronic device around the first electronic device and the second electronic device;
• according to the request, transmit, using the communication circuit, to the second electronic device, information for a broadcast isochronous group (BIG) event including a first broadcast isochronous stream (BIS) event for the first electronic device and a second BIS event for the second electronic device;
• and
• broadcast, using the communication circuit, at least one first packet through the first BIS event to synchronize the first audio signal with the second audio signal provided by broadcasting from the second electronic device at least one second packet through the second BIS event identified based on the information.
