Abstract

A method and a user equipment (UE) configured with one or more cells for feeding back channel information are discussed. The method according to an embodiment includes receiving information on a maximum number of ranks; transmitting first channel information generated based on rank information; and transmitting second channel information which is generated based on the same rank information as the rank information used for generating the first channel information. The maximum number of ranks is used to determine the rank information.
