TERMINAL DEVICE, BASE STATION DEVICE, TRANSMISSION METHOD AND TRANSMIT POWER SETTING METHOD

摘要

The objective of the present invention is to provide a terminal device capable of suppressing delay in switching between transmit/receive points, and of reliably switching between the transmit/receive points. In the device, a reception processing unit (203) receives control information including a transmission request for an A-SRS and a report request for a downlink CSI, whereupon a transmission signal formation unit (207) transmits the A-SRS at a transmit power set on the basis of the report request. In addition, if a report for each downlink CSI between a plurality of base stations is requested in the report request, the transmission signal formation unit (207) transmits the A-SRS at a first transmit power, whereas if a report for a downlink CSI between a single cell is requested in the report request, the A-SRS is transmitted at a second transmit power. The first transmit power is greater than the second transmit power.
