Title
(EN) APPARATUS AND METHOD FOR TRANSMITTING CHANNEL STATE INFORMATION IN A WIRELESS COMMUNICATION SYSTEM
(FR) APPAREIL ET PROCÉDÉ DE TRANSMISSION D'INFORMATIONS D'ÉTAT DE CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN)
An apparatus and method for transmitting channel state information in a wireless communication system are disclosed. The UE apparatus for transmitting channel state information includes a channel state measurement module for measuring a channel state based on a level of interference received from a neighbor cell, a channel state information generation module for generating channel state information for a plurality of resource regions or for periodic and aperiodic channel state information reporting modes using the measured channel state and offsets received from a serving BS, the offsets being set for the plurality of resource regions or the periodic and aperiodic channel state information reporting modes, and a transmission module for transmitting the generated channel state information to the serving BS.
