Method and apparatus for making HARQs in carrier aggregation systems
The present invention relates to a method and system for making a hybrid automatic repeat requests (HARQ) in a carrier aggregation system. The method receives downlink data through a first subframe of a first carrier, transmits acknowledgement/negative-acknowledgement (ACK/NACK) for the downlink data through a second subframe of a second carrier, and re-receives the downlink data through a third subframe of the first carrier, wherein the first carrier only includes the downlink subframes, and the second carrier includes the uplink subframes and the downlink subframes.
