Abstract: Methods and apparatuses are provided for reporting channel status by a user equipment (UE) in a communication system. Information on at least one channel status information reference signal is received from an evolved node B. A first channel status based on a first period and a first set of the at least one channel status information reference signal, is reported to the evolved node B. A second channel status based on a second period and a second set of the at least one channel status information reference signal, is reported to the evolved node B. The first channel status includes at least one of a precoding matrix indicator (PMI), a channel quality indicator (CQI), and a ranking indication (RI), and the second channel status includes at least one of a CQI, a PMI and a RI. The RI of the second channel status is same as the RI of the first channel status.
