Abstract
The present invention is designed to maintain reduced interference in a layered network like a HetNet and improve the overall system throughput performance. A radio base station apparatus has a normal/ABS pattern determining section () that determines a power ratio pattern that shows the power ratio between a reference signal (CRS) and a shared data channel signal (PDSCH) in each subframe, and a transmitting/receiving section () that transmits identification information for identifying the power ratio of each subframe in accordance with the determined power ratio pattern.
