Abstract: A method and apparatus for transmitting a data frame in a communication network, such as a wireless local area network (WLAN), a power line communication (PLC) network, or the like. A transmitter forms one expansion frame using more than one frame, transmits more than one generated expansion frame to a receiver, requests a block acknowledgement (ACK) frame for the transmitted expansion frames, and, after receiving the block ACK frame, re-transmits an expansion frame having an error by changing a transmission parameter.
