Abstract
The present invention is related to integrated multi-datastream transmission technology, more particularly, to integrated multi-datastream modulation technology. According to one aspect of the present invention, there is provided a modulation equipment (), including: a symbol integration means (), configured to combine a first bit stream with a second bit stream to form a symbol to be modulated; a symbol mapping means (), configured to map the symbol to be modulated into a QAM modulation symbol according to a set of predetermined mapping rules; wherein, in the set of predetermined mapping rules, multiple constellations corresponding to any first bit stream are located in at least two quadrants in the constellation diagram, while multiple constellations corresponding to any second bit stream are located in at least two quadrants in the constellation diagram. The integrated transmission of a first service data and a second service data (e.g., unicast service data and MBMS data) may be supported and has a better performance than the prior art especially in single cell scenario by using the method, equipment and device in the present invention.
