1. A method comprising:
- receiving a data signal and a control signal;
orthogonalizing channels for the control signal; and
multiplexing, at a symbol-level, the data signal and the control signal to output a multiplexed signal,wherein the step of orthogonalizing includes spreading, at a block level, the control signal.

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.
