TRANSMITTER APPARATUS, RECEIVER APPARATUS, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

In a terminal (200), a transmission control unit (206) identifies candidate resources on the basis of setting information and determines, on the basis of a trigger signal, a mapping resource, in which a second type of reference signal is mapped, in candidate frequency unit groups constituting the candidate resources. Each of the candidate resources is constituted by a plurality of fundamental subframe groups that are arranged at first intervals. N constituent subframes constituting each of the fundamental subframe groups are arranged at second intervals narrower than the first intervals. Each of the candidate frequency units of each candidate frequency unit group is a frequency unit specified by a predetermined frequency hopping pattern in M frequency units in each constituent subframe.
