Retransmission procedure and apparatus for handshaking protocol

摘要

Method and apparatus for minimizing a retransmission of messages when an error message is received during a communication handshaking procedure. A receiver, that detects an error message during the communication handshaking procedure, receives messages from a communication apparatus. When the receiver detects the error message, a retransmission requester transmits a retransmission request message to the communication apparatus.
