1. A method for feeding back channel information, the method comprising:
- receiving information on a maximum number of ranks;
if one or more cells are configured, performing a first feedback process and a second feedback process,wherein the first feedback process is configured to transmit first channel information generated based on rank information,wherein the second feedback process is configured to transmit second channel information,wherein the second channel information is generated based on the same rank information as the rank information used for generating the first channel information of the first feedback process, andwherein the maximum number of ranks is used to determine the rank information; and
receiving rank-related information determined by a base station based on the rank information.

Abstract
A method for feeding back channel information, and a user equipment (UE) therefore are discussed. The method according to one embodiment includes, if one or more cells are configured, performing a first feedback process and a second feeding process. The first feedback process is configured to transmit first channel information including rank information. The second feedback process is configured to transmit second channel information generated based on the same rank information as the rank information of the first feedback process.
