METHOD AND DEVICE FOR DATA TRANSMISSION |
摘要 |
Embodiments of the present invention provide a data transmission method that relates to the field of communications technologies and is invented for effectively improving the spectrum efficiency of data transmission. The data transmission method includes: mapping, to a resource element according to a preset rule, data that needs to be transmitted to a user equipment, where the preset rule includes: mapping data to the resource element corresponding to a non-zero power CSI-RS in a first set of the user equipment, unless the resource element is a specific resource element, where the specific resource element includes a resource element that is among the resource elements corresponding to the non-zero power CSI-RS in the first set and overlaps a resource element corresponding to a zero power CSI-RS; and transmitting the mapped data to the user equipment. The present invention is applicable to a radio communications system such as Long Term Evolution. |
