摘要： Provided is a cyclic shift sequence generation method which can prevent coming of an interference wave into a desired wave detection window even if a cyclic shift sequence has a high mutual correlation in different bandwidths, thereby improving a channel estimation accuracy in a base station. In this method, a cyclic shift sequence number to be allocated to a cell is decided in advance. Moreover, when the cyclic shift amount between cyclic shift sequences allocated in cells is Δ1 and the cyclic shift amount of the cyclic shift sequences allocated between the cells is Δ2, Δ1 and Δ2 are made different when generating a cyclic shift sequence.

摘要： Provided is a terminal apparatus in which, a transmission control unit (204) controls the transmission power of a sounding reference signal (SRS) by use of an offset value relative to the transmission power of a data signal, and a transmission unit (206) transmits the SRS by use of the transmission power as controlled. If a subframe to be used for transmitting the SRS is a predetermined subframe, the transmission control unit (204) uses a first offset value to control the transmission power of the SRS. Otherwise, the transmission control unit (204) uses a second offset value to control the transmission power of the SRS. The second offset value is an offset value that has been established so as to be transmitted to the serving cell of the terminal (200), and the first offset value is greater than the second offset value.

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 transmission 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 transmission 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 transmission power. The first transmission power is greater than the second transmission power.
