METHOD OF REMOVING REDUNDANT RETRANSMISSION, CAPABLE OF REMOVING A UNNECESSARY RETRANSMISSION REQUEST OF ARQ AND A REPETITIVE TRANSMISSION PROCEDURE OF DATA WHILE BEING INTERLINKED WITH ARQ(AUTOMATIC REPEAT REQUEST) AND HARQ(HYBRID ARQ)

摘要

PURPOSE: A method of removing redundant retransmission is provided to protect a waste of a wireless resource and an excessive transmission delay by prevent unnecessary retransmission to ARQ and HARQ.;CONSTITUTION: In a method of removing redundant retransmission, a lower layer of a reception terminal receives data from a transmitting terminal(S201). A lower layer of the receiving terminal determines whether transmission of the received data is fail or not(S202). The lower layer of the reception terminal finish data reception by transmitting the data to an upper layer(S207). The lower layer of the reception terminal calculates the number of transmission fail required for retransmission(S203). The reception terminal requires the retransmission of data by transmitting NACK to a transmitting terminal(S204). A lower object of the reception terminal delivers the transmission fail to the upper object of the reception terminal(S205). The upper object of the reception terminal reset a timer which is set to receive data again(S206).;COPYRIGHT KIPO 2010
