Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a base station device capable of normally performing CoMP communication without increasing overhead in upstream control channel.

SOLUTION: A spreading section 214 performs a primary spreading of a response signal using a ZAC system set by a control section 209. A spreading section 217 performs a secondary spreading of the response signal after CP addition using block wise spreading code system set by the control section 209. The control section 209 controls the cyclic shift amount in the ZAC system used for primary spreading by the spreading section 214 and the block wise spreading code system used for the secondary spreading by the spreading section 217 according to the set system number and hopping pattern. The hopping pattern set to the control section 209 is a hopping pattern commonly used for plural base stations which CoMP-receives the response signal.
