Abstract  Abstract

There is provided a radio communication device capable of reducing a control signal amount to be transmitted thereby increasing the data amount that can be transmitted and reducing power consumption as well as reducing interference to the other radio communication device thereby increasing the system capacity. In this device a control information extraction unit (105) extracts CQI count instruction information contained in the control information. Reception quality measurement units (113-1 to 113-n) measure the reception quality of each sub-carrier in the communication band. A CQI generation unit (114) generates CQI of some sub-carriers having a preferable reception quality in the communication band. A multiplexing unit (122) multiplexes the CQI sub-carrier number information which has generated the CQI and an ACK signal or a NACK signal. An SC selection unit (127) selects the number of sub-carriers having preferable reception quality and assigned by the CQI count instruction information from a base station device.

There is provided a radio communication device capable of reducing a control signal amount to be transmitted thereby increasing the data amount that can be transmitted and reducing power consumption as well as reducing interference to the other radio communication device thereby increasing the system capacity. In this device a control information extraction unit (105) extracts CQI count instruction information contained in the control information. Reception quality measurement units (113-1 to 113-n) measure the reception quality of each sub-carrier in the communication band. A CQI generation unit (114) generates CQI of some sub-carriers having a preferable reception quality in the communication band.

An SC selection unit (127) selects the number of sub-carriers having preferable reception quality and assigned by the CQI count instruction information from a base station device.

the through reducing the amount of control signal transmission capable of increasing the transmitted-data capacity also can reduce power consumption which can increase system capacity by reducing interference of the other wireless communication device of the wireless communication device. in the device a control information extracting part (105) extracts comprises CQI number indication information in the control information. measuring reception quality of each subcarrier communication band in the reception quality measuring section (113-1 to 113-n). CQI generating section (114) generates a CQI reception quality in the communication band is a good part of subcarriers. subcarrier number information multiplexer (122) generates CQI of the CQI and ACK signals or NACK signals are multiplexed. SC selecting section (127) selects indicating subcarriers of good received quality of the number information of the extension signal is assigned according to the CQI number by the base station device.
