TRANSMITTING APPARATUS AND TRANSMITTING METHOD OF BASE STATION, AND RECEIVING APPARATUS AND COMMUNICATION METHOD OF UE IN MOBILE COMMUNICATION SYSTEM

摘要

A receiving apparatus of a UE transmits at least one channel information among a plurality of channel information to a transmitting apparatus of a base station according to an adaptive transmission method set for a received signal. In addition, the receiving apparatus transmits channel state information generated on the basis of the plurality of channel information to the transmitting apparatus with a relatively long interval. The transmitting apparatus transmits traffic data to the transmitting apparatus by using the received channel state information and at least one of channel information and one of a plurality of adaptive transmission methods. Accordingly, the amount of channel information transmitted to the transmitting apparatus can be modified in accordance with an adaptive transmission method set for a received signal, thereby minimizing the amount of channel information fed back from the receiving apparatus and increasing system capacity.
