Abstract:
1. In a wireless communication system, a method for preparing data for transmission on a plurality of transmission channels, wherein each transmission channel is operative to transmit a respective sequence of modulation symbols, the method comprising: determining a number of information bits per modulation symbol supported by each transmission channel; identifying a modulation scheme for each transmission channel such that the determined number of information bits per modulation symbol is supported; determining a coding rate for each transmission channel based at least on the determined number of information bits per modulation symbol and the identified modulation scheme for the transmission channel, wherein at least two transmission channels are associated with different coding rates; encoding a plurality of information bits in accordance with a particular encoding scheme to provide a plurality of coded bits; puncturing the plurality of coded bits in accordance with a particular puncturing scheme to provide a number of unpunctured coded bits for the plurality of transmission channels; and adjusting the puncturing to achieve the different coding rates for the at least two transmission channels.
