Apparatus and method for link performance improvement of multicast service in wireless system

The present invention relates to an apparatus and method for link performance improvement of the multi-cast service from a wireless system, when is in one of the frame data is received, the process of reconstructing the data information of the data word using the packet, the information word packet during the restore of data failure using the, receiving parity packets of the data in the next frame, and restores the data by using the process for restoring the data using the received parity packets and the parity packets receiving the parity packets of the failed the data when, from the adjacent cell or sector by performing arbitrary hand-over (Autonomous handover) to and including the step of reconstructing the data using the received parity packet, the same amount of receiving a retransmission packet of the cell edge user, while using the radio resources The benefit of improving the link level performance of the multicast service of increasing cell-edge user to time, increase the multicast packet (outer coding rate) MCS level or the outer code rate for transmission, and further increase the overall cell performance (throughput) there is.
