ASYMMETRIC FEEDBACK FOR COORDINATED TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a feedback method related to a MIMO communication channel.SOLUTION: In a mobile communication terminal 24, a method is provided for receiving a signal transmitted through a first and a second communication channel from at least a first and a second base station 28A, 28B that operate in coordination with an adjustment transmission scheme. Each channel evaluation value of a communication channel is calculated based on the received signal. First and second feedback data indicative of each channel evaluation value of the first and second communication channels are generated in such a manner that the first feedback data includes a first data size and the second feedback data includes a second data size different from the first data size. The first and second feedback data are transmitted from the mobile communication terminal to at least one base station.
