Abstract

A terminal (20) comprising a transmitting section (203) configured to transmit an uplink shared channel; and a control section (401) configured to determine, when frequency hopping is applied to the uplink shared channel, a symbol for a demodulation reference signal of the uplink shared channel based on a mapping type of the uplink shared channel in the time direction by using a start symbol of each hop as a reference point, wherein when the mapping type is a first type in which a start symbol of the uplink shared channel is not fixed, the control section (401) is configured to determine each symbol for the demodulation reference signal in each hop to be at a same relative position from the start symbol of each hop, and when the mapping type is a second type in which the start symbol of the uplink shared channel is fixed, the control section (401) is configured to determine, based on an index of a first symbol for the demodulation reference signal, each symbol for the demodulation reference signal in each hop to be at different relative positions from the start symbol of each hop.
