METHOD AND DEVICE FOR RESOURCE MAPPING AND CODE DIVISION MULTIPLEXING

摘要

A method and device for resource mapping and code division multiplexing are provided by the present invention, which belong to the communication field. The method for resource mapping includes that: a kind of mapping scheme is selected from at least two kinds of preset mapping schemes, the pilot symbol corresponding to the selected mapping scheme and having the maximum transmission power is staggered at frequency and/or time with the pilot symbol corresponding to the mapping scheme selected by at least one neighbor cell and having the maximum transmission power (101); the resource mapping is performed in accordance with the selected mapping scheme (102). The present invention realizes the resource mapping by the way that each cell selects a kind of mapping scheme from at least two kinds of mapping scheme, thus effectively reducing the interference for the pilot symbol of the cell boundary user; by performing the vector exchange for the orthogonal matrix, multiple different code sequences are obtained and the code design is realized, thus effectively improving the imbalance problem for the output power of the pilot symbol.
