    Abstract: The invention provides a power control methodology that increases the performance and the throughput of wireless communication systems. In particular, the invention provides a reverse jamming prevention process that efficiently utilizes power resources in a communication system such as CDMA. The invention advantageously prevents reverse jamming due to link imbalance that results from differences in forward and reverse link coverage. According to the invention, an evaluation set (eset), which is a super set of the active set of base transceiver stations serving specific users, is determined to prevent the negative effects of reverse jamming. Excessive interference problems in the reverse link, particularly in high-speed wireless systems, are thus avoided.

    Abstract: The invention provides a novel methodology that increases the performance of wireless communication systems by efficiently managing the assignment of burst transmissions. The invention provides a mechanism for premature termination of burst transmissions, depending on a set of intelligent criteria. The invention checks for power overload conditions and excessive frame error rates (FER) in determining a premature burst termination. Also checked is a known time period which no burst shall exceed in transferring data. The invention advantageously increases the system throughput and data rates and maximizes power capacity in the data channels. In particular, transmission quality is maintained, as power overloading and excessive interference problems are circumvented. Systems resources are efficiently conserved and better utilized as a result.

    Abstract: A method and apparatus for adaptively adjusting the power of a probe signal to be transmitted by user equipment based on a characteristic of received signals and system constants so as to increase the likelihood that the probe signal will be detected by system equipment of a communication system. The Doppler shift of a received pilot signal is derived and an adjustment parameter is calculated based on the Doppler shift, time interval between successive probe transmissions and system constants. The adjustment parameter is applied to the probe signal to be transmitted to compensate for the effects of fading to be experienced by the probe signal to be transmitted.

    Abstract: A method and apparatus are provided for dynamically controlling a high speed wireless communication system to optimize utilization of system resources and thereby increase system throughput. The invention operates to determine an allocation of wireless transmission resources to each user application served by the wireless system in a manner to optimize transmission resources while meeting required QoS criteria for the served user application. After all user applications have been provided a transmission resource allocation in this manner, the total transmission resources so allocated are determined and compared with a ceiling transmission resource level for the wireless system. A portion of the difference between the ceiling and currently allocated transmission resource levels is then made available, according to the invention, to the served user applications in proportion to the initial allocation provided each user application.
