Disclosed are a system and a method for receiving an MBMS broadcasting service. In the present invention, in a mobile communication/wireless communication system, an MBMS service is provided by synchronizing a unicast bearer with a multicast bearer through scheduling information mapping at the time of transmitting a broadcast/multicast service through a unicast. Further, the present invention presents even a method for improving quality of experience (QoE) of the service by providing the MBMS service through the multicast bearer and the unicast bearer simultaneously. According to the present invention, MBMS services of various service qualities can be provided depending on wireless quality of a terminal or the capability of the terminal at the time of providing the MBMS service.
