Mobile station apparatus and receiving method

摘要

A mobile station apparatus is provided that performs receive processing efficiently and reduces unnecessary power consumption. In this mobile station apparatus, a signaling detector ( 71 ) detects the timing transmit diversity mode of the base station of the HSDPA serving cell changes and reports this change timing to a controller ( 72 ). The controller ( 72 ) controls an HS-PDSCH receive processor ( 40 ) and HS-SCCH receive processor ( 50 ) to stop receive processing with respect to the HS-PDSCH sub-frame and HS-SCCH sub-frame corresponding to the change timing.
