Abstract:
1. A transmitter apparatus of a reference signal, comprising: a reception section that receives setting information regarding a candidate resource to which a reference signal is mapped, in a physical layer; a specifying section that specifies the candidate resource on the basis of the setting information; a determination section that determines a mapping resource to which a reference signal is mapped on the basis of a trigger signal in a candidate frequency unit group forming the candidate resource; and a transmission section that maps a reference signal to the determined mapping resource and transmits the mapped reference signal, wherein the candidate resource includes a plurality of basic subframe groups disposed at a first interval, and N (where N is a natural number which is equal to or more than 2) constituent subframes forming each basic subframe group are disposed at a second interval shorter than the first interval, and each candidate frequency unit of the candidate frequency unit group is a frequency unit which is regulated by a predetermined frequency hopping pattern among M (where M is a natural number which is equal to or more than 2) frequency units of each constituent subframe.
