4. The method of claim 1 , wherein the first channel status information and the second channel status information are configured by a higher layer signaling.
5. A method for receiving a channel status report in a communication system, the method comprising:
receiving first channel status information in a second subframe based on a first offset, the first channel status information being generated based on a channel status information reference signal (CSI-RS) in a first subframe; and
receiving second channel status information in a fourth subframe based on a second offset, the second channel status information being generated based on a channel status information reference signal (CSI-RS) in a third subframe,
wherein an interval between the first subframe and the second subframe is greater than or equal to a predetermined value, and an interval between the third subframe and the fourth subframe is greater than or equal to the predetermined value, and
wherein the predetermined value is four.
6. The method of claim 5 , wherein a difference between the first subframe and the second subframe and a difference between the third subframe and the fourth subframe are at a smallest value greater than or equal to the predetermined value.
7. The method of claim 5 , wherein the channel status information reference signal (CSI-RS) in the first subframe and third subframe is received at a predetermined time period.
8. The method of claim 5 , wherein the first channel status information and the second channel status information are configured by a higher layer signaling.
9. A terminal for transmitting a channel status report in a communication system, the terminal comprising:
a transceiver for transmitting and receiving signals; and
a controller configured to generate first channel status information based on a channel status information reference signal (CSI-RS) in a first subframe, to transmit the first channel status information in a second subframe based on a first offset, to generate second channel status information based on a channel status information reference signal (CSI-RS) in a third subframe, and to transmit the second channel status information in a fourth subframe based on a second offset, wherein an interval between the first subframe and the second subframe is greater than or equal to a predetermined value, and an interval between the third subframe and the fourth subframe is greater than or equal to the predetermined value, and wherein the predetermined value is four.
10. The terminal of claim 9 , wherein a difference between the first subframe and the second subframe and a difference between the third subframe and the fourth subframe are at a smallest value greater than or equal to the predetermined value.
11. The terminal of claim 9 , wherein the channel status information reference signal (CSI-RS) in the first subframe and third subframe is transmitted at a predetermined time period.
12. The terminal of claim 9 , wherein the first channel status information and the second channel status information are configured by higher layer signaling.
13. A base station for receiving a channel status report in a communication system, the base station comprising:
a transceiver for transmitting and receiving signals; and
a controller configured to receive first channel status information in a second subframe based on a first offset, the first channel status information being generated based on a channel status information reference signal (CSI-RS) in a first subframe, and to receive second channel status information in a fourth subframe based on a second offset, the second channel status information being generated based on a channel status information reference signal (CSI-RS) in a third subframe, wherein an interval between the first subframe and the second subframe is greater than or equal to a predetermined value, and an interval between the third subframe and the fourth subframe is greater than or equal to the predetermined value, and wherein the predetermined value is four.
14. The base station of claim 13 , wherein a difference between the first subframe and the second subframe and a difference between the third subframe and the fourth subframe at are a smallest value greater than or equal to the predetermined value.
15. The base station of claim 13 , wherein the channel status information reference signal (CSI-RS) in the first subframe and third subframe is received at a predetermined time period.
