1. one kind is used on a plurality of transmission antennas, using more than two transport layers demodulated reference signal mode to be sent to the method for receiver node (12) at Resource Block in conveyer node (10);

  • Said conveyer node (10) and receiver node (12) are included in the radio circuit, and said method comprises;

    -with a plurality of code words Mapping(121) to said more than two transport layers, -according to fixed mode, with each transport layer of said more than two transport layers based on the transmission order Mapping(123) to corresponding demodulated reference signal port;

    Wherein each said demodulated reference signal port adds demodulated reference signal mode to said Resource Block;

    Said demodulated reference signal port is associated with two code division multiplexing groups according to association mode;

    Wherein the transport layer of each code division multiplexing group carries out code division multiplexing, and the transport layer of different code division multiplexing group carries out frequency division multiplexing - Precoding(125) each code word and the demodulated reference signal mode that carry through corresponding transport layer, and -in said Resource Block with the demodulated reference signal mode of precoding Transmit(127) to said receiver node (12).
