DEVICE, METHOD FOR ESTIMATING CHANNEL QUALITY, AND TRANSMISSION METHOD

摘要

A device is provided with an own mobile unit individual pilot receiving section (230) for receiving an individual pilot signal included in the individual pilot signal part of a data unit transmitted from a base station (10) to the mobile unit (20), an other mobile unit individual pilot receiving section (240) for receiving a signal included in an individual pilot signal part of a data unit transmitted from the base station (10) to a mobile unit other than the mobile unit (20), a CQI generating section (290) for estimating channel quality information indicating the reception environment of when the mobile unit (20) receives the data according to the individual pilot signal received by the own mobile unit individual pilot receiving section (230) and the signal received by the other mobile unit individual pilot receiving section (240), and a wireless section (310) for transmitting the channel quality information estimated by the CQI generating section (290) to the base station (10). As a result, the base station (10) can contribute to the optimization of allocation of a wireless resource.
