METHOD AND DEVICE FOR RESOURCE MAPPING AND CODE DIVISION MULTIPLEXING

摘要

The present invention discloses a method and an apparatus for resource mapping and code division multiplexing. In the present invention, each cell selects a mapping scheme among at least two mapping schemes to implement resource mapping, which effectively reduces 5 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, so that a problem that the output power of reference signal symbols is unbalanced can be effectively alleviated.
