BASE STATION, MOBILE TERMINAL, AND COMMUNICATION CONTROL METHOD

摘要

The present invention provides a base station, mobile terminal, and communication control method with which reference signals are appropriately transmitted and received even when the ratio of reference signals in a specified period increases. The base station transmits CSI-RS to a first mobile terminal capable of receiving CSI-RS and a second mobile terminal capable of receiving CSI-RS set at a lower ratio in the specified period than the first mobile terminal. The first mobile terminal allocates CSI-RS to a mutable CSI-RS resource at a ratio at which reception is possible. When a resource to which CSI-RS has been allocated is notified to the first mobile terminal and a resource to which CSI-RS has been allocated is notified to the second mobile terminal, some of the resources are notified as muted resources.
