Publication number: 20100235721Abstract: Described embodiments provide for rate matching with an encoded sequence of data bits. The encoded sequence of data bits is divided into two or more sub-blocks, with each sub-block having at least one column of bits, each including a set of valid bits. A set of dummy bits is generated and appended to each column of each sub-block. A starting point index for the set of valid bits within each sub-block is generated and the number of bits supported by the physical layer is determined. Only the valid bits of each sub-block are interleaved, based on each starting point index, until either i) there are no valid bits remaining, or ii) the number of interleaved bits reaches the number of bits supported by the physical layer. All dummy bits and any valid bits exceeding the number of bits supported by the physical layer are omitted.Type: ApplicationFiled: March 13, 2009Publication date: September 16, 2010Inventors: Moshe Bukris, Ido Gazit
