Abstract:
Provided is a terminal with which it is possible, in a heterogeneous cell network, to transmit a Periodic-Sounding Reference Signal (P-SRS) at a transmission bandwidth and power density necessary for carrying out both a process of selection of a transceiving participating base station and a process of frequency scheduling of a Physical Uplink Shared Channel (PUSCH). A terminal (300) comprises a receiving unit (301) which receives control information which includes information which denotes a P-SRS transmission parameter, and a transmission unit (303) which, using a transmission parameter which is included in the received control information, transmits a first P-SRS provided with a first bandwidth and a first power density at a first period, and transmits a second P-SRS provided with a second bandwidth which is narrower than the first bandwidth and second power density which is higher than the first power density at a second period.
