Abstract
An apparatus and method for optimizing a data rate in a wireless communication system supporting Hybrid Automatic Repeat reQuest (HARQ) are provided. The method includes estimating Channel State Information (CSI) of a signal to be transmitted, by using other CSIs received in a previous cycle; determining an instantaneous data rate, at which the CSI is transmitted with an optimal data rate, and the amount of redundancy information to be retransmitted; and retransmitting the redundancy information of the signal according to the amount of redundancy information and the instantaneous data rate, if a receiving end requests signal retransmission. Accordingly, the packet can be transmitted with the optimal data rate.
