TERMINAL, BASE STATION, COMMUNICATION SYSTEM, COMMUNICATION METHOD AND INTEGRATED CIRCUIT

摘要

There is provided a terminal (200) which communicates with a base station by using a resource element constituted by a sub-carrier and an OFDM symbol. The terminal includes a receiver (201), an uplink channel generator (241), and a transmitter (242). The receiver (201) receives a CSI reference signal transmitted from the base station. The uplink channel generator (241) generates an uplink channel including a first feedback information or a second feedback information which is feedback information generated by using the CSI reference signal, and is selected based on a configuration for the terminal. The transmitter (242) transmits the uplink channel to the base station. The first feedback information and the second feedback information are generated for a PDSCH which is assumed to be different from each other, in a CSI reference resource.
