Abstract  Abstract

A method and apparatus for channel coding and rate matching of the Physical Uplink Control Channel (PUCCH) and the Physical Downlink Control Channel (PDCCH) is disclosed that uses convolutional encoding to code the control channels. Rate matching is performed using a circular buffer based rate matching algorithm. A rate matching module may contain a single interleaver or may alternatively comprise a plurality of sub-block interleavers. Interleaved coded bits may be stored in the circular buffer in an interlaced format or output streams from separate sub-block interleavers may be stored contiguously. When a plurality of sub-block interleavers are used different interleaving patterns may be used. Rate matching may use bit puncturing or repetition to match the rate of the available physical channel resource. Rate matched output bits may be interleaved using a channel interleaver.
