Abstract
An operating method and an apparatus according to data duplicate retransmission in a mobile communication system are provided. A method of a User Equipment (UE) according to data duplicate retransmission in a mobile communication system includes storing a Media Access Control Protocol Data Unit (MAC PDU) received from an Evolved Node B (ENB) in a soft buffer decoding the MAC PDU determining whether the decoding is a first successful decoding of data of the corresponding soft buffer and determining whether to forward the decoded MAC PDU to an upper layer according to the determination result.

Claim
1. A method for processing data by a terminal in a mobile communication system, the method comprising:
receiving data from a base station;
determining whether the received data is retransmitted data based on a new data indicator;
determining whether corresponding data has been successfully decoded when the data is retransmitted data;
combining the received data with data stored in a buffer when the corresponding data has not been successfully decoded;
decoding the combined data;
determining whether decoding of the combined data is a first successful decoding of the corresponding data when the combined data is successfully decoded, and
delivering decoded data to a disassembly and demultiplexing entity when the decoding of the combined data is the first successful decoding of the corresponding data.
2. The method of claim 1, further comprising:
replacing the data stored in the buffer with the received data when the size of the received data is different from the size of the data stored in the buffer; and
decoding the data replaced in the buffer instead of the combined data,
wherein the determining of whether decoding of the combined data is the first successful decoding of the corresponding data comprises:
determining whether decoding of the data replaced in the buffer is the first successful decoding of the corresponding data when the data replaced in the buffer is successfully decoded.
3. The method of claim 2, wherein the replacing of the data stored in the buffer with the received data when the size of the received data is different from the size of the data stored in the buffer comprises:
comparing the size of the received data with the size of the data stored in the buffer after combining the received data with data stored in a buffer.
4. The method of claim 1, further comprising:
storing the received data in the buffer when the received data is initial transmission data;
decoding the received data;
determining whether decoding of the received data is the first successful decoding of the corresponding data when the received data is successfully decoded; and
delivering the decoded received data to the disassembly and demultiplexing entity when the decoding of the received data is the first successful decoding of the corresponding data.
5. An apparatus for processing data by a terminal in a mobile communication system, the apparatus comprising:
a transceiver configured to receive data from a base station; and
a controller configured to:
determine whether the received data is retransmitted data based on a new data indicator,
determine whether corresponding data has been successfully decoded when the data is retransmitted data,
combine the received data with data stored in a buffer when the corresponding data has not been successfully decoded,
decode the combined data,
determine whether decoding of the combined data is a first successful decoding of the corresponding data when the combined data is successfully decoded, and
deliver decoded data to a disassembly and demultiplexing entity when the decoding of the combined data is the first successful decoding of the corresponding data.
6. The apparatus of claim 5, wherein the controller is further configured to:
replace the data stored in the buffer with the received data when the size of the received data is different from the size of the data stored in the buffer,
decode the data replaced in the buffer instead of the combined data, and
determine whether decoding of the data replaced in the buffer is the first successful decoding of the corresponding data when the data replaced in the buffer is successfully decoded.
7. The apparatus of claim 6, wherein the controller compares the size of the received data with the size of the data stored in the buffer after combining the received data with data stored in a buffer.
8. The apparatus of claim 5, wherein the controller is further configured to:
control to store the received data in the buffer when the received data is initial transmission data,
decode the received data,
determine whether decoding of the received data is the first successful decoding of the corresponding data when the received data is successfully decoded, and
deliver the decoded received data to the disassembly and demultiplexing entity when the decoding of the received data is the first successful decoding of the corresponding data.
