  • Patent number: 6785227
    Abstract: A method and apparatus are provided for dynamically controlling a high speed wireless communication system capable of transmitting a message via a communication channel, to minimize the transmission power necessary for a single job and thereby increase system capacity. The communication channel is characterized by performance characteristics curves and physical channel characteristics curves. Channel conditions are sampled to model the performance characteristic curvers. Upon determining a minimum throughput to meet a Quality of Service requirement for user application, a first set of data pairs that correspond to the minimum throughput are determined from the performance characteristics curves. That first set of data pairs is in mapped to the physical channel characteristic curver and the data pair corresponding to minimum transmission power is then selected.

  • Publication number: 20020097686
    Abstract: The present invention is an adaptive system, which supports higher peak data rate and throughput in digital wireless communications, compared with other non-adaptive systems. One embodiment of the invention consists of three parts: the Long Term Prediction system for fast fading DS/CDMA mobile radio channel; the fast feedback system to enable the adaptive transmission; and, new system blocks that are supported/enabled and changes in the existing 3GPP WCDMA system specifications.
