A flexible data rate matching method in a 3GPP2 system is disclosed that supports
flexible data rate repetition on a physical layer of synchronous cdma2000 in an
interleaving process. The process includes repeating bits of a channel encoded
bitstream with one of a plurality of repetition factors, for matching a length
of a repeated bitstream to an interleaving depth, or alternatively, fixing an index
of an offset bit, where bit repetition of the channel encoded bitstream is started
therefrom, for making the repetition pattern of the channel encoded bitstream to
be a desired bit repetition pattern, fixing a repetition factor according to an
initial parameter defined by the index of a fixed offset bit, repeating a bit of
relevant index, and updating the initial parameter according to the fixed repetition
factor, and repeating a process of fixing the repetition factor of a next bit according
to the updated initial parameter, repeating the next bit, and re-updating the updated
initial parameter, for matching a length of the repeated bitstream to the interleaving depth.
