RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION DEVICE, AND RADIO COMMUNICATION METHOD.

摘要

Disclosed is a radio communication system comprising a first transmission line state-measuring section and a second transmission line state-measuring section, wherein when a second communication device measures the state of a transmission line between a first communication device and the second communication device using the reference signal from the first communication device, the first transmission line state-measuring section measures the state of the transmission line state including the interference due to the signal from another first communication device, and the second transmission line state-measuring section measures the state of the transmission line between the first communication device and the second communication device while suppressing the interference due to the signal from the another first communication device, whereby a proper feedback information can be generated regardless as to when cooperative communication is performed.
