Abstract
A method and apparatus for changing a Transmit Time Interval (TTI) based on a Hybrid Automatic Repeat Request (HARQ) process in a code division multiple access (CDMA) communication system that supports a packet data service through an Enhanced Uplink Dedicated transport Channel (E-DCH). According to the method and apparatus, a data transmission/reception is performed in a manner that a TTI change signal is received, the actual time point of TTI change is calculated based on the TTI change signal and the HARQ process of the previous TTI, and the TTI is changed at the calculated time point of TTI change.
