摘要：
Various embodiments provide a method for transmitting control information in a broadcast multicast system, the method includes: broadcasting identifier information of N Multicast Broadcast Single Frequency Network (MBSFN) areas to which the current cell belongs through a system message wherein N is an integer with N>1; transmitting indication information of control information of the N MBSFN areas through a system message or a Radio Resource Control (RRC) message; and transmitting the control information of the N MBSFN areas respectively through a Multicast Control Channel (MCCH) of the current cell according to the indication information. Various embodiments can guarantee normal working of a UE when the UE is located in an area overlapped by multiple MBSFN areas.
