1. An electronic device, comprising:
wireless communication circuitry;
a processor operatively connected with the wireless communication circuitry; and
a memory operatively connected with the processor,
wherein 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 through the wireless communication circuitry;
establish a second communication link with a second external electronic device through the wireless communication circuitry;
transmit, over the second communication link, first communication link information associated with the first communication link to the second external electronic device, wherein the first communication link information is used by the second external electronic device to monitor the first communication link;
receive first data from the first external electronic device over the first communication link; and
transmit a first response message for the first data to the first external electronic device over the first communication link,
wherein the instructions further cause the processor to:
receive a second response message transmitted over the first communication link by the second external electronic device, wherein the second response message includes a first FLOW (flow control) field and a first ARON (automatic repeat request number) field;
identify whether the first data is received by the second external electronic device based on the first FLOW field of the second response message:
form a third response message based on the first FLOW field of the second response message and whether the electronic device receives the first data, based on determining that a first ARON bit in the first ARON field of the second response message indicates negative acknowledgement (NACK); and
transmit the third response message over the first communication link to the first external electronic device.
