Title:
WIRELESS COMMUNICATION SYSTEM, MOBILE STATION DEVICE, WIRELESS COMMUNICATION METHOD, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2011/099324
Kind Code:
A1
Abstract:
The disclosed system enables the efficient transmission of a first and a second reference signal for channel measurement without deterioration in channel measurement accuracy, and enables the efficient transmission of a first and a second reference signal for channel measurement, and efficient transmission in a physical uplink control channel, without deterioration in communication quality. If the transmission of a first reference signal and the transmission of a second reference signal have occurred at the same timing (YES at step S101), a mobile station device transmits the first reference signal (step S102). However, if the transmission of the first reference signal and the transmission of the second reference signal have occurred at the same timing but in different component carriers (NO at step S101) then the mobile station device transmits the first reference signal and the second reference signal simultaneously (step S103).
