- Abstract
- Provided are a method and an apparatus for determining a reporting period of channel quality indicator. The method includes the steps of: a) estimating a channel gain through a channel received from a base station; b) calculating a weight by using a variable for determining a fairness value and the estimated channel gain, and estimating weight channel quality to the estimated channel gain by using the calculated weight; c) comparing the estimated weight channel quality and a threshold value; and d) feeding back estimated channel quality indicator by using wireless resources assigned for the channel quality indicator feedback only in case that the weight channel quality is higher than the threshold value.
