Claim:
1. A method of performing an uplink Hybrid Automatic Repeat Request (HARQ) operation in an asymmetric multicarrier communication network environment, the method comprising: transmitting, by a mobile station, a HARQ packet to a base station in a transmit time interval of one of a plurality of partitions of an uplink allocation interval on a first carrier; determining a HARQ feedback region in a subsequent downlink subframe for receiving HARQ feedback information corresponding to the transmitted HARQ packet, wherein the subsequent downlink subframe is partitioned into a plurality of HARQ feedback regions; and receiving, from the base station, the HARQ feedback information in the determined HARQ feedback region in the subsequent downlink subframe on a second carrier, wherein the first carrier and the second carrier comprise different frequency bands.
