Communication Device and Scheduling Method

摘要

A communication device which can reduce amount of control information, limit interference with other traffics, and prevent an increase in current consumption. In this device, a separation unit ( 105 ) separates radio resource allocation information, specific section information and transmission parameter information from a received signal. A specific section information control unit ( 106 ) selects a sub-carrier designated by the specific section information to allocate data to be transmitted to the own unit. A channel quality measuring unit ( 107 ) uses a pilot signal to measure the channel quality of the selected sub-carrier. A channel quality information creating unit ( 108 ) creates channel quality information indicating the measurement results input from the channel quality measuring unit ( 107 ). A multiplexing unit ( 109 ) multiplexes the transmission signal with the channel quality information.
