Abstract
An approach is provided for performing control signaling. Data and control information are received. The control information is orthogonalized using block-level spreading. The data and the orthogonalized control information are multiplexed at a symbol-level.

20. A system comprising:
-
a block-level spreading module configured to spread a modulated and encoded control symbol to output an orthogonalized control symbol; a multiplexer configured to multiplex a data symbol and the orthogonalized control symbol; a transform module configured to transform the multiplexed symbol using a transform function; and an inverse transform module configured to apply an inverse of the transform function to the transformed multiplexed symbol to output a transmission signal. - View Dependent Claims (21, 22, 23, 24, 25)
