1. A method in a mobile terminal of receiving control information in a multi-carrier wireless communication system, the method comprising:
- receiving information related to a link between a first forward link carrier and a first reverse link carrier, wherein the first forward link carrier is used to receive data and the first reverse link carrier is used to transmit data;
receiving information related to a link between a second forward link carrier and a second reverse link carrier, wherein the second forward link carrier is used to receive data and the second reverse link carrier is used to transmit data;
receiving power control information for the first reverse link carrier;
receiving power control information for the second reverse link carrier;
transmitting data via the first reverse link carrier;
transmitting data via the second reverse link carrier;
receiving an acknowledgement (ACK) signal for the data of the first reverse link carrier; and
receiving an ACK signal for the data of the second reverse link carrier,wherein the power control information for the first reverse link carrier and the power control information for the second reverse link carrier are received via a single forward link carrier,wherein the ACK signal for the data of the first reverse link carrier and the ACK signal for the data of the second reverse link carrier are received via a single forward link carrier, andwherein the first forward link carrier and the second forward link carrier are not the same.
