APPARATUS AND A METHOD FOR OPERATING FREQUENCY RESOURCES IN A BWA COMMUNICATION SYSTEM, ESPECIALLY FOR DIFFERENTLY APPLYING SUB-CARRIER HOPPING AND BAND HOPPING PATTERN SPEED ACCORDING TO A CSI PATTERN

摘要

A frequency resource operating apparatus and method for transmitting and receiving data at a different hopping pattern speed according to a CSI in a BWA communication system are provided. In a method of transmitting and receiving data using CSI in a mobile communication system, a BS sets the CSI of an MS to an initial CSI and sends data to the MS according to the initial CSI. The MS sends a downlink CSI to the BS. The BS groups the MS based on the downlink CSI and sends data to the MS according to a hopping pattern for the group of the MS among hopping patterns preset for predetermined groups.
