Mobile station, base station and communications method

摘要

A mobile station comprises a mapping portion that maps an uplink shared data channel to which an uplink shared control channel and a pilot channel pertain, on a resource block assigned by a base station, wherein plural resource blocks are arranged on a frequency axis and plural resource blocks are time-divisionally multiplexed on a time axis in an uplink; and a transmitting portion that transmits the uplink shared data channel mapped in the mapping portion. The mapping portion arranges the uplink shared control channel before and after the pilot channel in the uplink shared data channel to which the uplink shared control channel and the pilot channel pertain.
