1. A method of broadcasting and multicasting data in a wireless multi-carrier communication system, comprising:

  • processing a plurality of data streams to obtain a plurality of data symbol streams, one data symbol stream for each data stream;

    allocating transmission units to each of the plurality of data streams, each transmission unit corresponding to one subband in one symbol period and being usable to transmit one data symbol;

    mapping data symbols in each data symbol stream onto the transmission units allocated to the corresponding data stream; and

    forming a composite symbol stream with data symbols for the plurality of data streams mapped onto the allocated transmission units, wherein each data stream is independently recoverable by a receiver based on the data symbols included in the composite symbol stream for the data stream.
