Abstract:
1. A method of encoding data for transmission on a data channel to one or more users, comprising: determining which bits, from a total set of systematic bits, parity one bits and parity two bits sent from an encoder are to be subject to a HARQ (hybrid-automatic request) functionality in a HARQ data block and transmitted employing a set of channelization codes by a particular channel element, said determination being performed employing an inverse transformation of the HARQ function to determine which bits at an input of the HARQ data block will be included in an output of the HARQ data block to be transmitted by a particular channel element, the determining step including, channel coding the bits determined in the determining step in an HARQ data block using the two rate-matching stages and a virtual buffer, wherein the performing of the first rate matching includes,
