Abstract
A method for generating a Dedicated Reference Signal (DRS) is provided, which includes generating a Reference Signal (RS) sequence of each antenna port, spreading each RS sequence and obtaining an spread RS sequence, multiplying each spread RS sequence by a predefined scrambling code and obtaining a desired DRS sequence. An apparatus for generating a DRS is also provided. The problem of the imbalance of the power of OFDM symbols is cured, and DRS interference between different cells can be randomized.
