A method and apparatus for wireless communication in which groups of expected mobile device mobility speed ranges are established. A first sub-carrier block arrangement for the group having the lowest expected mobility speed range is determined. The first sub-carrier block arrangement is comprised of a plurality of sub-carriers. 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 is determined. The second sub-carrier block arrangement is comprised of the plurality of sub-carriers. The first and second sub-carrier block arrangements are different but use the same sub-carrier spacing and symbol duration.
