Abstract:
A method for efficiently transmitting control information may include allocating a portion of orthogonal frequency division multiple access (OFDMA) frames for transmission of a code division multiple access (CDMA) based signal. The CDMA-based signal may include data from one or more dedicated control channels. The method may also include converting the CDMA-based signal into a format that is suitable for transmission via OFDMA techniques. The method may also include transmitting the converted CDMA-based signal using a subset of available OFDMA subcarriers.
