Abstract

Provided is a method of transmitting and receiving data by a user equipment (UE), the method including receiving, by the UE, a first data stream including at least one of transmission data and a first error correction code regarding the transmission data, obtaining a second error correction code based on the transmission data obtained from the received first data stream, and transmitting a second data stream including at least one of recovered transmission data and the obtained second error correction code.

Claims

1. A method of transmitting and receiving data by a user equipment (UE), the method comprising:

receiving, by the UE, a first data stream comprising at least one of transmission data and a first error correction code regarding the transmission data;

obtaining a second error correction code based on the transmission data obtained from the received first data stream; and

transmitting a second data stream comprising at least one of recovered transmission data and the obtained second error correction code.

2. The method of claim 1, further comprising determining whether the transmission data is recoverable from the first data stream,

wherein the obtaining of the second error correction code comprises obtaining the second error correction code based on the transmission data recovered from the first data stream, if the transmission data is recoverable.

3. The method of claim 1, further comprising:

predicting a transmission environment between the UE and an external UE that receives the second data stream transmitted by the UE; and

determining at least one of a number of data packets included in the second data stream and a number of second error correction packets included in the second data stream, based on the predicted transmission environment.

4. The method of claim 1, wherein the obtaining of the second error correction code comprises:

transmitting and receiving information about each error correction code to and from another UE; and

obtaining the second error correction code based on received information about an error correction code of another UE,

wherein the error correction code of the UE and the error correction code of the another UE are different from each other.

5. The method of claim 1, wherein the obtaining of the second error correction code comprises obtaining the second error correction code based on information about an error correction code included in the received first data stream.

6. The method of claim 1, wherein the second data stream comprises transmission data comprising at least one data packet and a second error correction code comprising at least one error correction packets.

7. The method of claim 1, further comprising:

determining a number of packets included in the second data stream; and

determining packets included in the second data stream from among the at least one data packet and the at least one error correction packet, based on the determined number of packets.

15. A computer-readable recording medium having recorded thereon a program for executing the method of claim 1 on a computer.

8. A user equipment (UE) for transmitting and receiving data, the UE comprising:

a receiver configured to receive a first data stream comprising at least one of transmission data and a first error correction code regarding the transmission data;

a controller configured to obtain a second error correction code based on the transmission data obtained from the received first data stream; and

a transmitter configured to transmit a second data stream comprising at least one of recovered transmission data and the obtained second error correction code.

9. The UE of claim 8, wherein the controller is further configured to determine whether the transmission data is recoverable from the first data stream and obtain the second error correction code based on the transmission data recovered from the first data stream, if the transmission data is recoverable.

10. The UE of claim 8, wherein the controller is further configured to predict a transmission environment between the UE and an external UE that receives the second data stream transmitted by the UE and determine at least one of a number of data packets included in the second data stream and a number of second error correction packets included in the second data stream based on the predicted transmission environment.

11. The UE of claim 8, wherein the controller is further configured to transmit and receive information about each error correction code to and from another UE and obtain the second error correction code based on received information about an error correction code of another UE,

wherein the error correction code of the UE and the error correction code of the another UE are different from each other.

12. The UE of claim 8, wherein the controller is further configured to obtain the second error correction code based on information about an error correction code included in the received first data stream.

13. The UE of claim 8, wherein the second data stream comprises transmission data comprising at least one data packet and a second error correction code comprising at least one error correction packets.

14. The UE of claim 8, wherein the controller is further configured to determine a number of packets included in the second data stream and determine packets included in the second data stream from among the at least one data packet and the at least one error correction packet, based on the determined number of packets.
