Abstract: A system for a feedback reduction through resource sharing in a multicast environment is provided. The system for the feedback reduction comprises: a grade determination unit which determines the MCS grades of the user terminals; a code generation unit which generates codes corresponding to the MCS grades; a terminal transceiver unit which feeds back the generated codes to a base station, which are generated by the code generation unit, using a feedback resource allocated to a group; a grade confirmation unit which confirms an MCS grade of a user terminal by receiving the codes; and a base station transceiver unit which performs a multicast service at a transmission rate corresponding to a specific MCS grade among the MCS grades.
