Claim Text:
1. A data transmission method, comprising: when time division duplex uplink/downlink configurations of a plurality of cells aggregated by a user equipment, UE, are different and only unidirectional data transmission is allowed in an uplink/downlink collision subframe, determining, by the UE, an allowed data transmission direction of the uplink/downlink collision subframe, wherein if transmission directions of a subframe in different cells aggregated by the UE are different, the subframe is referred to as an uplink/downlink collision subframe; determining, by the UE, available subframes in an uplink data transmission direction and available subframes in a downlink data transmission direction in each cell aggregated by the UE respectively, wherein available subframes determined in a data transmission direction opposite to the allowed data transmission direction do not comprise the uplink/downlink collision subframe; and transmitting, by the UE, data in the available subframes in the uplink data transmission direction, and receiving data in the available subframes in the downlink data transmission direction.
