Abstract
In user terminal 20, reception section 202 and signal separation section 204 receive a data signal and a demodulation reference signal mapped to a downlink resource, and demodulation and decoding section 208 uses the demodulation reference signal to demodulate the data signal. A correction reference signal is mapped to the downlink resource according to a parameter related to user terminal 20 signaled to user terminal 20. Reception section 202 and signal separation section 204 specify a mapping pattern of the correction reference signal based on the parameter, and demodulation and decoding section 208 uses the correction reference signal to demodulate the data signal.
