Abstract
The present invention discloses a data transmission method base station and terminal. The method comprises: transmitting in every subframe used for transmitting multimedia broadcast multicast service (MBMS) n transport blocks (TBs) to terminals and transmitting to the terminals the correspondence between the MBMS corresponding to each TB in the subframe and the TB serial number of each TB in the subframe; wherein n is an integer greater than one a period of time occupies in every subframe by the TBs corresponding to same MBMS is same and each TB in the subframe corresponds to a unique TB serial number. The present invention can transmit two or more TBs to terminals in every subframe and the TBs transmitted in the subframe can correspond to different MBMSs thereby realizing the transmission of TBs corresponding to a plurality of MBMSs in a subframe and improving the spectrum effectiveness of the data transmission.
