Abstract
Provided is an error correcting method that can provide improved error correction efficiency in a multimedia broadcast/multicast service (MBMS) by marking the presence of an error in a Protocol Data Unit (PDU) with an error instead of discarding the erroneous PDU in an MBMS terminal of the MBMS system, which performs error correction in an application layer, and transmitting the erroneous PDU together with a PDU without an error to the application layer, and an error correction apparatus employing the method. The MBMS terminal includes: a radio link control (RLC) protocol processor configured to receive PDUs generated from the reception data, generate service data units (SDUs) by combining the PDUs, mark whether there is an SDU recovered from a PDU with an error, and output the SDUs; and a packet data convergence protocol (PDCP) processing means configured to receive and deliver the SDUs.
