    • A de-rate matching method and apparatus in a High Speed Downlink Packet Access (HSDPA) system are provided. In the de-rate matching apparatus and method, a collection buffer temporarily stores a received packet, a combining buffer stores the packet received from the collection buffer according to predetermined memory address information including information indicating the positions of bits punctured during the rate matching, a controller decodes high-speed shared common control channel (HS-SCCH) information including a predetermined hybrid automatic repeat request (HARQ) parameter received from the transmitter and provides overall control to de-rate matching between the collection buffer and the combining buffer, an address generator generates the memory address information based on the decoded HARQ parameter, an address buffer stores the memory address information, and a zero inserter initializes at least one of data stored at memory addresses of the combining buffer including memory addresses for the punctured, before the de-rate matching.

    • A transmitting/receiving apparatus and method for packet retransmission in a mobile communication system. Upon request for a retransmission from a receiver, a transmitter generates first coded bits by inverting initially transmitted coded bits, generates second coded bits by separating the initially transmitted coded bits into a first bit group having a relatively high priority and a second bit group having a relatively low priority and exchanging the first bit group with the second bit group, and generates third coded bits by inverting the exchanged coded bits. The transmitter selects one of the first coded bits, the second coded bits according to the sequence number of a retransmission request received from the receiver, and the third coded bits and maps the selected coded bits to modulation symbols. The transmitter then transmits the modulation symbols to the receiver.

    • An apparatus for retransmitting data at a retransmission request from a receiver by a transmitter in a CDMA mobile communication system including a turbo encoder with a given coding rate and initially transmitting systematic bits and parity bits obtained by encoding the data by the turbo encoder using one modulation mode among a plurality of modulation modes. A controller determines a modulation mode to be used between the transmitter and the receiver in response to the retransmission request. A distributor distributes coded bits obtained by encoding the data at the coding rate into systematic bits and parity bits. A selector selects coded bits transmittable by the determined modulation mode among the systematic bits and the parity bits at the initial transmission, if the determined modulation mode is different from the modulation mode used at initial transmission. A modulator modulates the transmittable coded bits into modulated symbols according to the determined modulation mode.
