1. A method for transmission of orthogonal frequency division multiplexed (OFDM) symbols in subframes comprising:

  • partitioning each of a plurality of sequential frames into a plurality of sub-frames, wherein the sequential frames are defined according to a reference system standard, each of the sequential frames including a legacy preamble, wherein a first of the sequential frames is pre-designated for downlink transmissions and a second of the sequential frames is pre-designated for uplink transmissions;

    transmitting a first of the plurality of sub-frames with a non-legacy preamble provided at a fixed offset relative to a location of the legacy preamble of the first sequential frame during-the first sequential frame; and

    transmitting a second of the plurality of sub-frames with a non-legacy preamble provided at the fixed offset relative to a location of the legacy preamble of the second sequential frame during the second sequential frame.
