Abstract
A mobile communication system, base station device, and mobile wireless terminal are provide which are capable of improving throughput and/or communication quality in the mobile wireless terminal when an HSDPA (High Speed Downlink Packet Access) method is applied to W-CDMA (Wideband Code Division Multiple Access) communication. A base station device transmits an empty pattern of a channelization code set for an HS-SCCH (High Speed Shared Control CHannel), which is used as an advance notice of transmission for a downlink employed in the HSDPA method, to the mobile wireless terminal. The mobile wireless terminal, when having received the advance notice of transmission for the downlink employed in the HSDPA method from the base station device, adds assumed power for transmission of the HS-DPCCH (High Speed Dedicated Physical Control CHannal) data to the estimated transmission power value to be used for judgement as to whether a TFC (Transport Format Combination) of a DPCH (Dedicated Physical CHannel) is usable or not.
