A METHOD OF COOPERATIVELY RELAYING DATA IN CELLULAR NETWORKS FOR A BROADCAST MULTICAST SERVICE

摘要

A method of receiving subpackets in a mobile communication system for a broadcast multicast service (BCMCS) using a single frequency carrier is disclosed. The method comprises: receiving a first broadcast subpacket from a base station (BS) at a first time slot; receiving at least one subsequent broadcast subpacket of the first broadcast subpacket from the BS at a second time slot; and receiving at least one relayed broadcast subpacket from at least one relay station (RS) at the same time slot as the second time slot, wherein information of the first broadcast subpacket, the at least one subsequent broadcast subpacket and the at least one relayed broadcast subpacket are the same, and wherein the at least one relayed broadcast subpacket is at least one of a space-time coded version of the first broadcast subpacket and a broadcast subpacket having different parity bits than that of the first broadcast subpacket.
