Provided are a data transmission method and device, and a UE, which relate to the field of communications. The method comprises: receiving a downlink CQI which is fed back by a first UE, and determining a first downlink MCS of the first UE according to the downlink CQI fed back by the first UE; according to the first downlink MCS of the first UE, allocating a transmission resource of the first cell to the first UE, and the first cell being a serving cell of the first UE; acquiring an uplink channel matrix of a sub-bandwidth (SB) level of each cell in a measurement set of the first UE; according to the uplink channel matrix of the SB level of each cell in the measurement set of the first UE, determining an SINR of a downlink transmission stream to be sent of each cell in a transmission set of the first UE; and according to the SINR of the downlink transmission stream to be sent, determining a second downlink MCS of the first UE. The present invention can fully utilize the channel quality and improve the transmission efficiency.
