FIELD: radio engineering, communication.SUBSTANCE: each cell selects a mapping scheme from at least two mapping schemes to implement resource mapping, which effectively reduces interference imposed on reference signal symbols of users at the edge of a cell; vector switching is performed for an orthogonal matrix to obtain multiple different codeword sequences and implement codeword design.EFFECT: problem that the output power of reference signal symbols is unbalanced can be effectively alleviated.12 cl, 8 dwg, 6 tbl |
