Abstract: Disclosed is an electronic device which includes wireless communication circuitry, a processor, and a memory. The memory stores one or more instructions that, when executed, cause the processor to establish a first communication link with a first external electronic device, to establish a second communication link with a second external electronic device, to transmit first communication link information for estimating a channel of the first communication link to the second external electronic device over the second communication link, to receive first data from the first external electronic device over the first communication link, and to transmit a first response message for the first data to the first external electronic device over the first communication link. The first response message includes a bit configured not to be processed by the first external electronic device, and the bit includes reception information about the first data of the electronic device.

Abstract: According to an embodiment of the disclosure, an electronic device comprises: a wireless communication circuitry configured to support a Bluetooth network; at least one processor; and a memory operatively connected with the at least one processor, wherein the memory stores instructions that, when executed, cause the at least one processor, the plurality of operations comprising: establishing a first link with a first external electronic device, based on the Bluetooth network; receiving information associated with a second link created between the first external electronic device and a second external electronic device, from the first external electronic device; attempting to receive a first data packet transmitted from the second external electronic device by monitoring the second link based at least partially on the information associated with the second link; identifying whether a response message is received from the first external electronic device; transmitting, to the second external electronic device,
