WIRELESS COMMUNICATION SYSTEM, MOBILE STATION DEVICE, BASE STATION DEVICE, WIRELESS COMMUNICATION METHOD, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2011/083706
Kind Code:
A1
Abstract:
Disclosed is a wireless communication system wherein optimum transmission power control is performed with respect to a periodic SRS and an aperiodic SRS. In the system, a mobile station device (1) transmits first reference signals or second reference signals to a base station device (3). The base station device (3) notifies the mobile station device (1) of first parameters to be used for the purpose of setting transmission power with respect to transmission of the first reference signals, and second parameters to be used for the purpose of setting transmission power with respect to transmission of the second reference signals. The mobile station device (1) sets the transmission power with respect to the transmission of the first reference signals using the first parameters, and also sets the transmission power with respect to the transmission of the second reference signals using the second parameters.
