摘要：
Provided is an apparatus and method for enhancing the link performance of a multicast service for UEs in a wireless system. In the method, multicast data received in an Nth frame is recovered using systematic packets. When the recovery fails, parity packets are received in an (N+1)th frame and are used to recover the multicast data. When the recovery fails again, an autonomous handover is performed to receive parity packets from a neighboring cell or sector, which are used to recover and the multicast data.
