Abstract  Abstract

A wireless transmit/receive unit (WTRU) and a base station for channel coding and rate matching of the Physical Uplink Control Channel (PUCCH) and the Physical Downlink Control Channel (PDCCH) is disclosed comprising a convolution encoder. A rate-matching module coupled to said convolutional encoder further coupled to a circular buffer performs rate matching. Rate-matching module may be coupled to a single interleaver or may alternatively be coupled to a plurality of sub-block interleavers. The sub-block interleavers may store coded bits in said circular buffer in an interlaced format or separate sub-block interleavers may output coded bit streams and store them contiguously in said circular buffer. Sub-block interleavers may be configured to perform different interleaving patterns. Said rate-matching module may be configured to perform bit puncturing or repetition to match the rate of the available physical channel resource. A channel interleaver coupled to the rate-matching module may be configured to interleave the rate-matched output bits.
