Embodiments of the present invention provide a method, device, and UE for data transmission, which relate to the field of communications. The method includes: receiving a downlink CQI fed back by the first UE, and determining the downlink CQI of the first UE according to the downlink CQI fed back by the first UE. The first downlink MCS: according to the first downlink MCS of the first UE, allocate the transmission resource of the first cell to the first UE, and the first cell is the serving cell of the first UE; acquire the measurement set of the first UE The sub-bandwidth SB-level uplink channel matrix of each cell; according to the SB-level uplink channel matrix of each cell in the measurement set of the first UE, determine each cell in the transmission set of the first UE to be sent The SINR of the downlink transmission flow; Determine the second downlink MCS of the first UE according to the SINR of the downlink transmission flow to be sent. The present invention can make full use of channel quality and improve transmission efficiency. |
