Title:
通信装置、制御情報受信方法および集積回路
Document Type and Number:
Japanese Patent JP5714159
Kind Code:
B2
Abstract:
A wireless communication base station device which makes it possible to provide a base station, terminal and CCE allocation method capable of reducing the number of times blind decoding of a terminal is performed, without increasing the CCE block rate, even when a plurality of unit bands are set in a terminal. In this device, a search space setting section (103) sets in each of a plurality of unit bands a common search space in respect of a terminal which is communicating using the plurality of unit bands and other terminals, and sets in each of the plurality of unit bands an individual search space in respect of the terminal. An allocation section (106) allocates control information solely to CCEs within the common search spaces set in specified unit bands among the plurality of unit bands, or solely to CCEs within individual search spaces set in specified unit bands.
