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 wireless communication system, the method comprising:
receiving data from a base station;
storing the data in a buffer when a transmission of the data is an initial transmission;
decoding the data stored in the buffer;
determining whether decoding of the data is a first successful decoding of the data when the data is successfully decoded; and
delivering the decoded data to a disassembly and demultiplexing entity when the decoding of the data is the first successful decoding of the data.
2. The method of claim 1, wherein the storing of the data comprises replacing data stored in the buffer with the data.
3. The method of claim 1, further comprising:
determining whether the data is the initial transmission based on a new data indicator.
4. The method of claim 1, further comprising:
determining whether the data is successfully decoded;
generating an acknowledgement (ACK) for the data when the decoding of the data is successful; and
generating a non-acknowledgement (NACK) for the data when the decoding of the data is not successful.
5. The method of claim 1, further comprising:
discarding the decoded data when the decoding of the data is not the first successful decoding of the data.
6. An apparatus for processing data by a terminal in a wireless communication system, the apparatus comprising:
a transceiver configured to receive data from a base station; and
a controller coupled with the transceiver and configured to:
store the data in a buffer when a transmission of the data is an initial transmission,
decode the data stored in the buffer,
determine whether decoding of the data is a first successful decoding of the data when the data is successfully decoded, and
deliver the decoded data to a disassembly and demultiplexing entity when the decoding of the data is the first successful decoding of the data.
7. The apparatus of claim 6, wherein the controller is further configured to replace data stored in the buffer with the data.
8. The apparatus of claim 6, wherein the controller is further configured to determine whether the data is the initial transmission based on a new data indicator.
9. The apparatus of claim 6, wherein the controller is further configured to:
determine whether the data is successfully decoded,
generate an acknowledgement (ACK) for the data when the decoding of the data is successful, and
generate a non-acknowledgement (NACK) for the data when the decoding of the data is not successful.
10. The apparatus of claim 6, wherein the controller is further configured to discard the decoded data when the decoding of the data is not the first successful decoding of the data.
11. The method of claim 1, further comprising:
determining whether a transport block size for the data is different from a previous transport block size for previous data when the transmission of the data is not an initial transmission; and
if the transport block size is different from the previous transport block size, replacing data stored in the buffer with the data.
12. The apparatus of claim 6, wherein the controller is further configured to:
determine whether a transport block size for the data is different from a previous transport block size for previous data when the transmission of the data is not an initial transmission; and
if the transport block size is different from the previous transport block size, replace data stored in the buffer with the data.
