    摘要： An apparatus and method for reducing power consumption of a receiver by performing a Hybrid Automatic Repeat reQuest (HARQ) according to a detected decoding error are provided. The apparatus includes a decoding reliability metric generator for setting a decoding result as a decoding reliability metric, which is a reference value for determining a code block having a decoding error, based on a decoding result, a decoding reliability metric buffer for storing the decoding reliability metric set by the decoding reliability metric generator and a code block controller for, when the decoding error occurs, identifying code blocks having the decoding error by checking the decoding reliability metric and for controlling to decode the identified code blocks.

    摘要： A transmitting device in a mobile communication system is disclosed. In the transmitting device, an encoder receives an information bit stream in a frame, which is as long as an integer multiple of a predetermined value, and generates an information symbol, a first parity symbol, and a second parity symbol by encoding each information bit. An interleaver sequentially arranges the information symbols and the first and second parity symbols by rows in an array with an integer number of rows and an integer number of columns. The interleaver reorders the columns in the array according to a predetermined rule. The interleaver further outputs a plurality of radio frames in a stream, by reading the symbols by going down each column, starting at the leftmost column and proceeding right. Each radio frame has a predetermined size. A demultiplexer demultiplexes each of the radio frames received from the interleaver into a stream of information symbols, a stream of first parity symbols, and a stream of second parity symbols. A rate matcher bypasses the stream of information symbols and punctures the streams of the first and second parity symbols for rate matching.

    摘要： Disclosed is an apparatus for transmitting a sequence of information bits and sequences of parity bits to a receiver in a transmitter of an HARQ transmission system. A turbo encoder receives a sequence of L information bits, and generates the sequence of information bits and M sequences of L parity bits for the information bits, wherein M is determined depending on a transmission code rate. A redundancy selector includes the sequence of information bits in an initial data block during initial transmission, and uniformly includes non-transmitted parity bits out of parity bits provided from each sequence of the parity bits in a retransmission data block upon every receipt of a retransmission request from the receiver.
