Claim Text:
1. A method of transmitting feedback information at a user equipment (UE) in a multi-carrier wireless communication system, the method comprising: when single carrier is assigned to the UE, receiving signals through an assigned forward link carrier; and transmitting, through an assigned reverse link carrier corresponding to the assigned forward link carrier, feedback information including hybrid automatic repeat request (HARQ) feedback information related to the signals received through the assigned forward link carrier; and when multi-carriers are assigned to the UE in a such way that a new carrier is additionally assigned to the UE in addition to the assigned single carrier, receiving a first signal through the assigned forward link carrier of the multi-carriers assigned to the UE; receiving a second signal through an additionally assigned new forward link carrier of the multi-carriers assigned to the UE, the second signal being different from the first signal; and transmitting first HARQ feedback information related to the first signal and second HARQ feedback information related to the second signal, wherein the first HARQ feedback information related to the first signal received through the assigned forward link carrier is transmitted by the UE through the assigned reverse link carrier, wherein the second HARQ feedback information related to the second signal received through the additionally assigned new forward link carrier is also transmitted by the UE only through the assigned reverse link carrier among the assigned reverse link carrier and an additionally assigned new reverse link carrier configured for the UE, wherein, when the single carrier is assigned to the UE, the HARQ feedback information is transmitted through a control channel of the assigned forward link carrier, wherein, when the multi-carriers are assigned to the UE, the second HARQ feedback information related to the second signal is not transmitted by the UE through a control channel of the additionally assigned new reverse link carrier, wherein the assigned forward link carrier and the additionally assigned new forward link carrier are different forward link carriers, wherein the assigned reverse link carrier and the additionally assigned new reverse link carrier are different reverse link carriers, and wherein the feedback information comprises information indicating a best pilot type for a best channel condition of each antenna from among predefined pilot types of different sub-carriers.
