Device and method for transmitting response packet

A first electronic device comprising:

• a memory;
• a communication module configured to perform communication with a second electronic device and a third electronic device;
• and
• at least one processor operatively connected with the memory and the communication module,
• wherein the memory stores instructions configured to, when executed, cause the first electronic device to:
• share information about a received packet with the second electronic device to obtain first information indicating whether the first electronic device and the second electronic device each receive a data packet from the third electronic device during a first time period,
• in case that the first information indicates that the first electronic device and the second electronic device each fail to receive the data packet during the first time period, transmit a first response packet indicating a negative acknowledgment (NACK) to the third electronic device,
• share the information about the received packet with the second electronic device to obtain second information indicating whether the first electronic device and the second electronic device each receive the data packet retransmitted from the third electronic device during a second time period after the first time period,
• identify whether the first electronic device and the second electronic device each receive the data packet at least one time during the first time period and the second time period based on the first information and the second information, and
• transmit a second response packet indicating NACK or an acknowledgment (ACK) based on a result of the identification to the third electronic device.
