DEVICE FOR TRANSCEIVNG DATA ACCORDING TO RADIO LINK PROTOCOL IN MOBILE COMMUNICATION SYSTEM AND METHOD THEREOF

摘要

PURPOSE: A device for transceiving data according to an RLP(Radio Link Protocol) in a mobile communication system is provided to supply a retransmission method on the basis of an identifier number for efficiently transmitting data when the data is transceived according to the RLP, so as to make the RLP raise a transmission efficiency. CONSTITUTION: A data transmitter transmits a transmission RLP frame with a sequence number, and transmits the RLP frame of the sequence number according to a retransmitting request to a requested identifier number. A data receiver decides a new sequence number of an RLP frame secondly received from the sequence number of the received RLP frame. If the new sequence number of the RLP frame and the sequence number of the RLP frame are not equal to each other, the data receiver requests to retransmit a corresponding sequence number and an identifier number to the data transmitter.
