The embodiment of the invention provides a method, data transmission transmitter and receiver used in digital subscriber line DSL, the method includes determining a bit loading correspondence, correspondence, the correspondence between the sequence of bit loading including loading bits of all subcarriers K lines in each and all sub sub carrier carrier and loading the number of bits in each line of the K lines including N sub carriers, K is greater than or equal to 2 positive integers, N is a positive integer; according to the corresponding relationship between the bit loading of data transmission will be more special were loaded into K*N sub carriers in K lines to the K*N sub carrier; the receiving end sends a bit after loading. The embodiment of the invention realizes the binding of multiple lines through the arrangement between the bit loading and the subcarriers of different lines, and improves the binding efficiency.
