OFDM system and method for supporting a wide range of mobility speeds

A computer program product, tangibly embodied in a computer storage medium for executing instructions on a processor, the computer program product being operable to cause a machine to:

• establish groups of expected mobile device mobility speed ranges;
• determine a first sub-carrier block arrangement for the group having the lowest expected mobility speed range, the first sub-carrier block arrangement being comprised of a plurality of sub-carriers;
• and
• determine a second sub-carrier block arrangement for a group having an expected mobility speed range faster than the expected speed range of the lowest expected speed range group, the second sub-carrier block arrangement being comprised of the plurality of sub-carriers, the first and second sub-carrier block arrangements being different but using a same sub-carrier spacing and symbol duration, wherein the second sub-carrier block arrangement includes at least one disabled sub-carrier.
