Abstract  Abstract

This base station device can avoid PUCCH resource collisions among terminals while suppressing an increase in PUCCH resources even if a plurality of search spaces are set regarding ePDCCH with respect to a single terminal. In the device a setting unit (102) sets at a terminal (200) in a data-assignable region a first search space and a second search space which are candidates for assigning control information and each of the first search space and the second search space is configured from a plurality of control channel elements. A signal assignment unit (105) assigns control information to each of the first search space and the second search space. A setting unit (102) allocates numbers in ascending order to the plurality of first control channel elements configuring the first search space and allocates numbers that are the same as or numbers that are greater than the numbers allocated to the plurality of first control channel elements to the plurality of second control channel elements configuring the second search space.
