1. An apparatus comprising:

  • a plurality of transmission path circuits comprising;

    a spreader circuit that is configured to spread a first input data to generate parallel chips, the first input data being from a first set of users;

    a first mapping circuit that is configured to map each of the parallel chips to a first set of subcarriers including one or more subcarriers;

    a converter circuit that is configured to convert a second input data to parallel bits, the second input data being from a second set of users; and

    a second mapping circuit that is configured to allocate each user of the second set of users to a second set of subcarriers including one or more subcarriers, and to map the parallel bits from each user of the second set of users to the one or more subcarriers allocated to the respective user;

    wherein mapping of the user data to the first and second set of subcarriers includes frequency domain mapping.
