Method and device for applying adaptive link in communication system

摘要

Provided are a method and an apparatus of transceiving a signal using a link adaptation in a communication system, particularly, a method of dividing a resource region into a plurality of resource regions, and applying different line adaptations to the resource regions. A method of controlling a link of a terminal in a mobile communication system receives at least two downlink channel signals to estimate states of received channels, generates a channel discrepancy report when states of channels exceed a preset threshold, and reports the channel discrepancy report to a base station through a preset uplink channel. A method of controlling a link of a base station receives a channel discrepancy report through an uplink channel, and determines MCS and transmission power of downlink channels based on the received channel discrepancy report and transmits the determined MCS and transmission power to the terminal through a downlink channel.

1. A method of controlling link adaptation of a terminal in a mobile communication system, the method comprising:
measuring channel states of a first region and a second region of downlink, respectively, to generate channel state information of the first region and the second region of downlink; determining whether a channel discrepancy report occurs based on the channel state information of the first region and the second region of downlink; generating the channel discrepancy report including information on the difference between channel state information of the first region and the second region, if it is determined whether the channel discrepancy report occurs; and transmitting the channel state information including the channel discrepancy report to a base station through a preset uplink channel.
