Abstract: A method and apparatus of a user equipment are provided for transmitting a channel status report in a communication system. The method includes receiving first information for at least one channel status report; generating a first channel status report corresponding to the first information for the at least one channel status report based on a reference signal in a first subframe; and transmitting the first channel status report based on the first information for the at least one channel status report in a second subframe. The first information for the at least one channel status report comprises information for a period and an offset, and a difference between the first subframe and the second subframe is a smallest value greater than or equal to a predetermined value.
