METHOD AND APPARATUS FOR IMPROVING PERFORMANCE OF AUTOMATIC REPEAT REQUEST PROTOCOL USING HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method and apparatus for transmitting data in a transmitter using HARQ (Hybrid Automatic Repeat reQuest) feedback information in a mobile communication system. The method includes receiving a local ACK for an arbitrary data block n transmitted to a receiver Determining whether to retransmit the data block n according to a local ACK reception step and a channel state of a HARQ feedback message reception time point corresponding to the local ACK.
