Abstract
For Quality of Service (QoS) implementation in a multiple-access communication system, a base station processes data transmissions from terminals for all QoS classes supported by the system and obtains status information for the data transmissions. The status information may indicate whether each packet is decoded correctly or in error and the delay for each packet. For each QoS class, the base station derives one or more metrics based on the status information for data transmissions from disadvantaged terminals and updates the QoS parameter based on the metrics and requirements for the QoS class. The QoS parameter for each QoS class determines the transmit powers for the data transmissions sent for that QoS class. The base station broadcasts the QoS parameters for all QoS classes. Each terminal uses the QoS parameter for an applicable QoS class for power control of the data transmission sent to the base station.
