    摘要: To increase the number of CSI-RSs for interference measurement to improve interference measurement accuracy, a first reference signal for channel state measurement and a second reference signal for interference measurement are assigned to reference signal resources defined for transmission of the first reference signal, and a mobile terminal apparatus that supports both the first reference signal and the second reference signal is notified of pattern information to identify an assignment pattern of the first reference signal and the second reference signal. A second mobile terminal apparatus that supports the first reference signal and that does not support the second reference signal is notified of pattern information to identify an assignment pattern of the first reference signal, and of assignment information indicating that resources assigned the second reference signal are assigned a third reference signal of zero power for channel state measurement.

    摘要: The present invention is designed to provide a mobile terminal apparatus, a radio base station apparatus and a radio communication method which, even when a MIMO technique and a CoMP technique are applied together, can optimize the effects of both techniques. The mobile terminal apparatus estimates downlink channel states using reference signals included in downlink signals from a plurality of cells, determines the PMI for each cell and inter-cell phase difference information, from the channel states of the plurality of cells, such that the combinations of the PMI of each cell and inter-cell phase difference information become optimal, measures channel quality from the determined PMIs and inter-cell phase difference information, and transmits the PMI for each cell, the inter-cell phase difference information and channel quality information, to a radio base station apparatus.

    摘要: The present invention provides a mobile terminal apparatus, a base station apparatus, and a communication control method, which allow control suitable for interference reduction in a layered network such as HetNet, and which support a next-generation mobile communication system. A mobile terminal apparatus has a receiving section (103) that receives radio frames of a lower cell, in which a protected subframe, the transmission of which by a higher cell is suppressed, and a non-protected subframe, the transmission of which by the higher cell is not suppressed, coexist, a measurement section (112) that measures reception quality from reference signals multiplexed individually on the protected subframe and the non-protected subframe, a feedback information reduction section (114) that calculates a difference value between the reception quality of the protected subframe and the reception quality of the non-protected subframe, and a transmission section (103) that reports reception quality information of the protected subframe, and the difference value calculated in the feedback information reduction section (114), to a base station apparatus (20B).
