The invention discloses a method for transmitting and receiving multimedia broadcast and multicast services under TTD; all the cells in each base station form exactly the same MBMS symbol level data for spreading spectrum and scrambling, thereby forming baseband signals which are to be treated with transmitting in each cell; when the signals are transmitted, each cell uses different basic training sequences; according to system information, user equipment UE carries out channel evaluation to obtain the channel impulse response of each cell, and respectively calculates a system matrix corresponding to each cell and combines the system matrixs to a compound system matrix; an estimated MBMS service symbol level data is obtained by combining, detecting and processing the received baseband data and operated by demodulation and coding, thereby obtaining the original data of the MBMS service. The invention reduces the service interference, provides diversity and amplification and improves the transmission performance of the MBMS service.
