BASE STATION AND TERMINAL

摘要

A base station is capable of efficiently notifying a terminal of control information. The base station communicates with the terminal using a sub-frame including a plurality of resource block pairs. The base station sets a second control channel region in the terminal through RRC signaling that is higher-layer control information, the second control channel region being a region set differently from a first control channel region in which a first control channel is to be arranged. The base station transmits control information for the terminal by mapping the control information to a second control channel that is to be arranged in the second control channel region. The first control channel region is set in the sub-frame to be specific to the base station, and the second control channel region is set in the sub-frame to be specific to the terminal in units of the resource block pairs.
