  • Patent number: 9083496
    Abstract: A system and method for processing signals in a communication system is disclosed herein. The system and method comprises processing steps and processing logic for generating a downlink subframe comprising a preamble and a plurality of data bursts within a predetermined frequency band; embedding first and second sets of downlink subframe parameters in the downlink subframe; transmitting the downlink subframe; receiving the downlink subframe; processing data in the preamble to obtain channel quality indicator (CQI) information; and using the CQI information to select either the first set or set second set of downlink subframe parameters to process the data bursts in the downlink subframe.
    Type: Grant

  • Patent number: 7599321
    Abstract: An uplink access method in a mobile subscriber station of a broadband wireless access communication system prioritizes uplink bandwidth allocation according to QoS types of requested service. A scheduling priority is assigned to each type of service flow to guarantee the highest data rate for the high QoS service flows, and then the uplink data grants are scheduled based on this assigned priority. By assigning a priority to each connection based on the service type flow, the higher data rate connections will always have the opportunity to transmit uplink data to fulfill the high data rate QoS requirement, and fragmentation will occur only on the last lowest priority Connection ID (CID) based on the size of the last remaining data grant. The uplink access method further prevents the high priority service from stealing bandwidth from data grants intended for lower priority services by identifying when the data grant is mismatched from the amount requested by the lower level services.
