WIRELESS COMMUNICATION SYSTEM, BASE STATION DEVICE, TERMINAL DEVICE, AND WIRELESS COMMUNICATION CONTROL METHOD

摘要

In order to improve the throughput properties of a system overall while ensuring interference reduction in a hierarchical network such as a HetNet, a wireless base station device is provided with: a Normal/ABS-pattern determination unit (2041) for determining a power ratio pattern expressing, for each subframe, the power ratio between a reference signal (CRS) and a shared data channel signal (PDSCH); and a transmission/receiving unit (203) for transmitting identification information for identifying the power ratio of each subframe, according to the determined power ratio pattern.
