Patent ID: 8879489

Claim:
A method of configuring control information for more than one subframe allocation pattern (SAP) for a multimedia broadcast/multicast service (MBMS), comprising: determining subframes that can be allocated to the MBMS in units of at least one radio frame (RF); comparing, in RF units, periods of respective allocation patterns of subframes actually allocated to the MBMS among the subframes that can be allocated to the MBMS, so as to set a common subframe allocation period in which the more than one SAP is repeated; and configuring control information including information about at least one subframe allocated for the MBMS in the common subframe allocation period, wherein the control information includes upper control information about at least one subframe that can be allocated to the MBMS in the common subframe allocation period, and lower control information including information about at least one subframe allocated to at least one multicast channel (MCH) for the MBMS, wherein the lower control information includes information about the position of the last subframe allocated to each MCH as information used for classifying the MCH.
