Abstract
A data transmission method is disclosed in the present invention, where the method includes: mapping a data stream to be transmitted to an orthogonal frequency division multiplexing access, OFDMA, sub-carrier; scheduling the OFDMA sub-carrier; multiplexing the OFDMA sub-carrier to generate an OFDMA frame; and transmitting the OFDMA frame. A data transmission apparatus and a data receiving apparatus are also disclosed in the present invention. Through the present invention, a cross connection capability on the basis of the OFDMA sub-carrier is implemented, and in this way, not only all convergence services from a slave node to a master node are supported, but also a private line connection between two slave nodes is supported.
