Claim Text:
1. A method of transmitting a channel state information (CSI) in a wireless access system supporting multiple cells, the method comprising: calculating a number of resource elements (REs) using a maximum bit size among a bit size of the CSI for a first cell and a bit size of the CSI for a second cell, when a timing of a periodic CSI report for the first cell and a timing of a periodic CSI report for the second cell collide with each other; adjusting bits of the CSI having a higher priority between the CSI for the first cell and the CSI for the second cell to match the maximum bit size; and transmitting the adjusted bits of the CSI having the higher priority to a base station in a manner of mapping the adjusted bits to the calculated REs, wherein the calculating the number of the REs includes calculating a number (Q′) of the REs by a formula, wherein the formula is represented as follows: and wherein O indicates a bit number of the CSI, L indicates a cyclic redundancy check (CRC) bit number, β
