Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a communication device and a transmission method capable of increasing reception performance of CQI and a reference signal.

SOLUTION: A phase table storage 112 stores a phase table in which a cyclic shift amount and a complex coefficient {w1 W2} for multiplying a reference signal are associated with each other. A complex coefficient multiplication section 113 reads out the complex coefficient corresponding to a cyclic shift amount which is indicated by a piece of resource allocation information from the phase table storage 112 and multiplies the read out complex coefficient to the reference signal to change a phase relation among reference signals in a slot.
