Method for control transmission of channel quality information according to time-variant channel in wireless telecommunication system

The present invention relates to a method and apparatus for efficiently transmitting channel quality information on a radio channel in a mobile communication system. The invention, by changes adaptively according to the reporting cycle of channel quality information to change the degree of the time-varying characteristics and or the channel quality information according to the Doppler frequency of the radio channel and drives the channel state information transmitted in a mobile communication system, unnecessary frequent reducing the information transmission only can reduce the uplink interference power level, but can also reduce power consumption of the terminal.
