Abstract
This user terminal is equipped with a receiving unit which receives, from a base station device, a downlink signal which includes a demodulation reference signal for a plurality of ports multiplexed in the time direction; a control unit which separates, from the downlink signal, the demodulation reference signal for the port assigned to the host device; and a channel estimation unit which calculates a channel estimation value using the separated demodulation reference signal. The control unit specifies the multiplexing method for the plurality of ports selected on the basis of at least one of carrier frequency, propagation environment, user terminal performance and base station performance, and separates the demodulation reference signal according to the specified multiplexing method.
