Method and apparatus for notifying a subframe configuration of multicast broadcast single frequency network

An apparatus for notifying Multicast Broadcast Single Frequency Network (MBSFN) subframe configuration, comprising an evolved Node B (eNB) apparatus which comprises a processor coupled to a memory storing instruction, the processor is configured to read and execute the instructions stored in memory for:

• sending the MBSFN subframe configuration of a first node, via an X2 interface, to a plurality of second nodes, wherein the MBSFN subframe configuration of the first node includes X2 configuration update messages of the first node if the MBSFN subframe configuration of the first node changes;
• receiving the MBSFN subframe configurations of the respective second nodes as feedback;
• comparing the MBSFN subframe configurations of the respective second nodes with the MBSFN subframe configuration of the first node, and setting system information or a radio resource control (RRC) connection reconfiguration information according to the comparison result;
• wherein the system information or the RRC connection reconfiguration information includes a first bit sequence set based on the outcome of the comparison result, if the MBSFN subframe configuration of the second node is fed back to the respective first nodes;
• wherein the processor is further configured to:
• configure MBSFN subframes for a serving cell of the first node according to the comparison result in such manner that the MBSFN subframes configured for the serving cell of the first node are different from MBSFN subframes configured for cells of the second nodes.
