Abstract:
Disclosed herein are system, method, and computer program product embodiments for providing an efficient way to signal a tone mapping in a wireless communication protocol. Embodiments operate by receiving a frame for a wireless communications protocol. The embodiments extract a unique value from a tone mapping field in a preamble of the frame. The embodiments look up a resource block allocation for a portion of the tone space in a lookup table using the unique value. The embodiments map the tones of the portion of the tone space to one or more resource blocks based at least in part on the determined resource block allocation.
