An electronic device (101, 501) comprising: a communication module configured to support a first communication protocol and a second communication protocol; a processor operably connected to the communication module; and a memory operably connected to the processor, wherein the memory stores instructions that, when executed, enable the processor to: establish a first connection based on the first communication protocol with a first external electronic device; identify a second external electronic device by obtaining identification information corresponding to the second external electronic device and a connection state of the second external electronic device using the second communication protocol; produce a first message including a proposed schedule related to at least one further available window, FAW, determined based at least in part on information about the first connection and the connection state of the second external electronic device, the at least one determined FAW being included in an interval between synchronized time durations, wherein the first message comprises at least one of channel information, band information, a start offset, a bit duration, and a period, which are related to the at least one determined FAW; transmit the produced first message to the second external electronic device using the second communication protocol; receive, from the second external electronic device, a second message in response to the first message using the second communication protocol, wherein the second message is configured as a schedule response comprising one of acceptance, refusal, or modification proposal with respect to the proposed schedule; and schedule, based at least in part on the received second message, a data link based on the second communication protocol. a communication module configured to support a first communication protocol and a second communication protocol;
