1. A Carrier Aggregation, CA, based data transmission method, comprising:

  • an evolved NodeB, eNB, configuring a user equipment with at least two Time Division Duplex Uplink and Downlink, TDD UL/DL, configuration sets, wherein each TDD UL/DL configuration set comprises at least one cell; and

    the eNB configuring a cell respectively in each of the at least two TDD UL/DL configuration sets as an Especial Cell, Ecell;

    wherein the eNB configuring a cell in each TDD UL/DL configuration set as an Ecell comprises;

    when the TDD UL/DL configuration set comprises only one cell, then configuring the cell as an Ecell; and

    when the TDD UL/DL configuration set comprises at least two cells, then configuring a cell with a highest channel quality as an Ecell or configuring a cell subject to a lowest interference as an Ecell or configuring a cell with the highest channel quality and subject to the lowest interference as an Ecell or configuring a cell with a highest or lowest cell index as an Ecell.
