1. A terminal apparatus that receives signals from a first cell to which the terminal apparatus belongs and from a second cell, the terminal apparatus comprising: a radio receiver, which, in operation, receives information indicating subframes that include a subframe in which no downlink data is transmitted by the second cell, and receives a reference signal that is transmitted from the first cell to which the terminal apparatus belongs and that is transmitted on the subframe in which no downlink data is transmitted by the second cell; and a Channel Quality Indicator (CQI) measurement circuit, which, in operation, measures CQI using the received reference signal that is transmitted on the subframe in which no downlink data is transmitted by the second cell, wherein the CQI measurement circuit, in operation, measures the CQI for a subframe, in which the second cell causes no interference to the first cell to which the terminal apparatus belongs, based on said information.
