Abstract  Abstract

A method and apparatus for fast retransmission of a signal in a communication system. When a packet is directed to a receiving terminal device and the receiving terminal device demodulates the packet, the transmitting terminal device transmits a transmission signal in a packet format to the receiving terminal device. Subsequently, the receiving terminal device calculates the quality criterion of the packet and compares the calculated quality criterion with the quality criterion included in the packet. If the quality criteria match, the packet proceeds to the next process. If the quality criteria do not match, the receiving terminal device transmits a request for packet retransmission. The transmitting terminal device determines which packet needs to be retransmitted based on the request for retransmission. If the delivery of a packet according to the above fails, an attempt is made to retransmit according to a conventional sequence number based mechanism, for example the radio link protocol.
