Abstract:
Disclosed are a wireless communication method, a wireless communication base station device, and a wireless communication terminal device that dynamically switch the transmission slot of an SRS of each terminal within a cell while suppressing an increase in the number of signaling bits. A terminal (100) and a base station (200) are each provided with a table wherein FH flags for SRS and transmission power data of each slot are mapped to two-bit notification bits. In this table, transmission power data indicating SRS transmission by slot 1 and slot 2 and FH flags are mapped, and an FH flag is not mapped to transmission power data indicating SRS transmission by slot 1 or slot 2. The base station (200) notifies the terminal (100) of the FH flag data and the SRS transmission power data by means of transmitting scheduling data containing the notification bits to the terminal (100).
