Abstract
A transmission/reception apparatus and method for performing packet retransmission considering a channel environment in a CDMA mobile communication system. Upon receiving a retransmission request from a receiver, the apparatus and method selects a modulation type to be used according to a condition of a transmission channel, and changes the previously used puncturing pattern in order to output the proper number of coded bits for the selected modulation type.
