Abstract
Systems and methods for future-proofed control signaling are disclosed herein. A waveform enabling broadcast transmission of physical layer frames having variable parameters can be extended to allow for future additions to the control signaling structure without breaking compatibility with existing receivers. In some embodiments, new signaling parameters can be added in an existing portion of a preamble and the length of the modified parameter set can be indicated to legacy receivers. In some embodiments new signaling parameters can be added at the end of the existing preamble and viewed as reserved bits by legacy receivers.
