SYSTEM AND METHOD FOR ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS

摘要

An embodiment OFDMA frame includes a header with signal (SIG) fields that are encoded at different sampling rates than one another. In one example, a first signal field is encoded at a 64 point fast frequency transform (FFT) sampling rate, and the second SIG field is encoded at a 256 point FFT sampling rate. The first SIG field may carry parameters for decoding the second SIG field, and the second SIG field may carry resource allocation information for a payload of the OFDMA frame. The first SIG field may carry an identifier of an access point that transmits the OFDMA frame.
