    摘要： A rate matching method is provided for a mobile communication system that performs an adjustment to a code rate based on an optimal level by puncturing or repetition to respective bit streams of transport channels. The rate matching method is preferably applicable to uplink and downlink rate matching for channel coding including turbo coding, convolutional coding and the like. The rate matching method for uplink can include executing coding for bits of a transport channel, and branching off the bits into a plurality of sequences, constructing a first interleaving pattern for the plurality of sequences, constructing a virtual interleaving pattern for at least one sequence based on a mapping rule with a corresponding first interleaving pattern and calculating different bit shifting values in each column of each virtual interleaving pattern. Then, a bit position to be punctured is determined in each constructed virtual interleaving pattern using the calculated bit shifting values.

    摘要： A method for matching a rate in a mobile communication system causes puncturing or repetition in a fixed pattern, in which puncturing or repetition is applied to each bitstream on transport channels supporting different services in a next generation mobile communication system of the W-CDMA (Wideband Code Division Multiple Access) system. The method comprises the steps of (1) subjecting a bitstream on a transport channel for use in supporting a particular service to channel coding, (2) determining an initial error offset value for use in avoiding all the puncturing only in a particular bitstream among one or more than one bitstreams produced by the channel coding, (3) periodically subtracting a decrement from the determined initial error offset value, for puncturing a bit at a relevant position when a result of the subtraction satisfies a puncturing condition, (4) adding an update error parameter determined as the maximum bit size among TF (Transport Format) transportable during one TTI (Transport Time Interval) of the transport channel after the puncturing to a result of the subtraction, for updating an initial error offset value, and (5) periodically subtracting a decrement from the updated initial error offset value, for determining a position of a relevant bit to be punctured at the next time.
