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.
