Abstract
A terminal apparatus includes a transmitter configured to transmit an SRS in an SRS resource, and a receiver configured to receive a PDCCH to which DCI is mapped, wherein the DCI indicates the SRS resource, the number of SRS ports for the SRS resource is eight, the eight SRS ports are mapped across S OFDM symbols, transmission power is determined for the SRS, and a linear value of the transmission power is equally split for 8/S of the SRS ports.
