Abstract

A method and an apparatus are provided for generating feedback in a communication system. The method includes receiving information about first Evolved Node Bs (ENBs) and a threshold for the first ENBs which are powered off at a specific time; measuring a channel status for each of second ENBs which are subject to channel status measurement; selecting a third ENBhaving an optimal channel status from among the second ENBs based on the measured channel statuses; generating first feedback information including a cell index and channel status information for the third ENB; measuring a channel status for each of thesecond ENBs while the first ENBs are powered off; selecting a fourth ENB having an optimal channel status from among the second ENBs based on the measured channel statuses; and generating second feedback information including a cell index and channel status information for the fourth ENB.
