APPARATUS AND METHOD FOR CHANNEL QUALITY INDICATION REPORTING FOR REDUCING OVERHEAD OF UPLINK

摘要

A CQI transmitting device for reducing the uplink overhead and a method thereof are provided to reduce the power loss and overhead which are caused in the uplink due to unnecessary CQI transmission. A CQI transmission period change information generator(220) performs the correlation operation between the previous CQI and current CQI, and then changes the CQI transmission period according to a result value of the operation. A CQI calculation/transmission unit(214) calculates the CQI and transmits the calculated CQI to a base station by the changed transmission period.
