US 7,127,661 B2 · Method of configuring transmission in mobile communication system

Abstract

Method for configuring a transmission chain in a 3GPP2 system for supporting a flexible or variable data rate of an information bitstream in a process for mapping an information bitstream of a data rate on a physical layer, including the steps of (1) channel coding the information bitstreams with bit rates different from each other into turbo codes or convolution codes having a value inverse of 1/coding rate, and (2) repeating coded bitstream when the channel coded bitstream is smaller than a desired interleaving size, and puncturing the coded bitstream when the channel coded bitstream is greater than the desired interleaving size, for matching the channel coded bitstream to the interleaving size.

Dependent claims

A method of rate adaptation in a communication apparatus, comprising:

encoding information bits by an encoder at a coding rate, the coding rate being fixed to a specific value among at least two different values using a puncturing block in the encoder according to a ratio of a channel interleaver size and a number of the information bits;
performing repetition or puncturing of the coded bits for matching a size of the coded bits to the channel interleaver size;
and
interleaving the result of the repetition or puncturing according to the channel interleaver size.
