  • for a plurality of codeword sequences and a plurality of reference signal sub-carriers in a resource block, determining a mapping relationship between each codeword sequence and a reference signal sub-carrier;

    multiplexing, on each of the reference signal sub-carriers, reference signal symbols of multiple space layers in the resource block according to the codeword sequence corresponding to the reference signal sub-carrier; and

    transmitting the multiplexed reference signal symbols of the space layers;

    wherein each codeword sequence comprises a codeword A, a codeword B, a codeword C and a codeword D, arranged in an arranging order, and arranging orders of the codeword A, the codeword B, the codeword C and the codeword D in the codeword sequences are different from each other.
