Abstract:
1. A receiving station configured to transmit orthogonal frequency division multiplexed (OFDM) signals in accordance with a multiple-input multiple-output (MIMO) communication technique, the receiving station comprising: physical (PHY) layer circuitry to receive a preamble at a requested burst size from a transmitting station; and processing circuitry to evaluate the received preamble for a plurality of potential subcarrier modulation assignments and a plurality of fragment sizes to determine potential link data rates, wherein the processing circuitry is configured to select a combination of one of the potential subcarrier modulation assignments and one of the potential fragment sizes to achieve a highest of the potential link data rates, wherein the PHY layer circuitry is configured to transmit a message indicating the selected subcarrier modulation assignments and the selected fragment size to the transmitting station, wherein the transmitting station is configured to fragment network layer packets according to the selected fragment size for aggregation according to the requested burst size, and configured to transmit aggregated fragments in bursts in accordance with the selected subcarrier modulation assignments, and wherein the receiving station is configured to individually error-check fragments of the selected fragment size received in the bursts to request possible retransmission of individual fragments.
