Transmitting apparatus and method

Abstract

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.
