Abstract:
1. A communication system which uses an OFDM (Orthogonal Frequency Division Multiplexing) method as a downlink access method from a base station to a mobile terminal and uses a SC-FDMA (Single Career Frequency Division Multiplexing) method as an uplink access method from the mobile terminal to the base station, wherein two or more MBSFN (Multimedia Broadcast multicast service Single Frequency Network) areas in each of which MBMS (Multimedia Broadcast Multicast Service) is provided on a single frequency are configured, wherein the base station belonging to a plurality of MBSFN areas is adapted to transmit a scheduling information for each MCCH (Multicast Control Channel) of the plurality of MBSFN areas by BCCH (Broadcast Control Channel), wherein the mobile terminal is adapted to receive the scheduling information by the BCCH, and wherein the scheduling information includes a MCCH repetition period and a MCCH starting point value, corresponding to each of the plurality of MBSFN areas, and the MCCH is multiplied by a scrambling code related to each MBSFN area ID of the plurality of MBSFN areas.
