Communication system, terminal, and base station

Abstract

There are provided a base station, a terminal, and a communication system in a wireless communication system in which a base station and a terminal communicate with each other, in which the base station and the terminal can efficiently perform communication. The communication system includes a higher layer processing unit 605 configured to configure, at the base station, for each terminal, a first reference signal configuration for configuring a measurement target for channel state reporting, configured to configure, at the base station, for each terminal, a second reference signal configuration specifying a resource element to be excluded from the target of data demodulation in a case where the terminal demodulates data, and configured to configure, at the base station, for each terminal, a third reference signal configuration for configuring a measurement target for which a reference signal received power is to be measured by the terminal.

1 . A terminal device comprising:
 higher layer processing circuitry configured to receive a first reference signal configuration and a report configuration via a radio resource control signal, the first reference signal configuration comprising one or more combinations of first channel state information reference signal (CSI-RS) index and a CSI-RS measurement configuration, and   the report configuration comprising one or more second CSI-RS indices;   measurement circuitry configured to measure reference signal received powers (RSRPs) of one or more first CSI-RSs respectively identified by one or more first CSI-RS indices; and   transmitting circuitry configured to transmit a measurement report based on the report configuration, wherein   the measurement report includes the one or more second CSI-RS indices and the respective RSRPs of the one or more first CSI-RSs identified by the one or more second CSI-RS indices.
