1. A method for configuring a central subcarrier, comprising:

  • mapping a first downlink control channel onto a part (f1) of a downlink bandwidth (fW) of a cell, and configuring a first virtual central subcarrier in f1; and

    mapping a downlink data channel onto fW of the cell, and configuring a central subcarrier on fW, whereinf1 is different or partly different from a bandwidth f2 mapped to a second downlink control channel of the cell or a neighboring cell, an overlap between f1 and f2 is at least one subcarrier, or at least one idle subcarrier exists between f1 and f2, or at least one non-idle subcarrier and at least one idle subcarrier exist between f1 and f2; and

    the first virtual central subcarrier is located on a grid position of a central frequency, a distance between the first virtual central subcarrier and a second virtual central subcarrier configured in f2 is an integer multiple of a frequency domain width of the subcarrier, and borders of physical resource blocks (PRBs) are aligned between the cell and the neighboring cell.
