Zusammenfassung:	Embodiments of the present invention provide a data transmission method and apparatus, and UE, relating to the field of communications. The method includes: receiving a downlink CQI fed back by first UE, and determining a first downlink MCS of the first UE according to the downlink CQI fed back by the first UE; allocating a transmission resource of a first cell to the first UE according to the first downlink MCS of the first UE, where the first cell is 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; determining, according to the uplink channel matrix of the SB level of each cell in the measurement set of the first UE, an SINR of a downlink transmission stream to be sent by each cell in a transmission set of the first UE; and determining a second downlink MCS of the first UE according to the SINR of the downlink transmission stream to be sent. In the present invention, channel quality can be fully used, and transmission efficiency can be improved.
