Method and apparatus for transmitting and receiving evolved multimedia broadcast and multicast service data

The invention discloses a sending method of multimedia broadcast and multicast service data based on region group division, comprising that processing channel code and data modulation on multimedia broadcast and multicast service data, confirming special scrambling code of multimedia broadcast and multicast service region group, confirming special scrambling code of multimedia broadcast and multicast service regions, for the processed multimedia broadcast and multicast service data, using region group special scrambling code to scramble the multimedia broadcast and multicast service data, andadding a reference signal scrambled by the region group special scrambling code and a reference signal scrambled by the region special scrambling code, emitting the scrambled multimedia broadcast andmulticast service reference signals and data. The invention can realize radio combination or radio combination and soft combination at user terminal, to obtain group increment.
