Abstract:
A user terminal receives a downstream link data signal, a demodulation reference signal for demodulating the downstream link data signal, and a downstream link signal including a downstream link control signal; calculates a channel estimation value using the demodulation reference signal; demodulates the downstream link data signal using the channel estimation value; and demodulates the downstream link control signal using the channel estimation value calculated from the demodulation reference signal mapped to a symbol before a symbol to which the downstream link control signal is mapped in a sub-frame.
