Abstract: An uplink transmission power control method and a user equipment are provided, where the method includes: determining, by a UE, whether uplink channels are simultaneously transmitted over adjacent subframes between multiple carriers; where the adjacent subframes between the multiple carriers are partially overlapped; and timing advance values of the multiple carriers are different; and if uplink channels are simultaneously transmitted over adjacent subframes between multiple carriers, processing, by the user equipment, an uplink channel transmitted over the last symbol on a partially overlapped subframe of another carrier except a carrier having the greatest timing advance value, so that total transmission power of the uplink channels is lower than the maximum transmission power or an interference level of the user equipment.

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.
