Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a communication device a communication method and an integrated circuit reducing inter-sequence interference on a pilot signal between terminals with the suppression of inter-sequence interference among a plurality of pilot signals used in an identical terminal even when SU-MIMO and MU-MIMO are simultaneously applied.

SOLUTION: A base station device 100 includes: a transmission RF unit 103 which transmits to a terminal control information for identifying correspondence in which one of a plurality of cyclic shift amounts is associated with one of a plurality of orthogonal sequences for each of a plurality of layer numbers; and Based on the correspondence specified by the control information a reception RF unit 104 which receives a signal generated using the cyclic shift amount for each layer number and the orthogonal sequence and transmitted from the terminal. The cyclic shift amount takes 12 values from 0 to 11 and to an identical layer number among the plurality of layer numbers two cyclic shift amounts of which difference is 6 are respectively associated with different orthogonal sequences.
