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: In a method and system for controlling base station processing unit overload and buffer overflow in a unified manner, one or more processing units of the base station are monitored to determine if the processing unit(s) has entered an overload condition. If so, on a per flow basis, the system generates an advertise window for controlling the amount of data in the data flow, as transmitted to the processing unit from an upstream entity. The advertise window is generated taking into consideration both processor overload and buffer overflow factors. By incorporating these factors, the advertise windows collectively serve to limit both processor overload and buffer overflow, on a system wide basis.

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.

Abstract: A method for adjusting a protocol signal to be transmitted based on adjustments made to a detected protocol signal. The detected protocol signal carries adjustment information made to such signal to increase the likelihood of the signal bei ng detected. The adjustment information is retrieved from the detected protocol signal an d is used to adjust at least one characteristic of the protocol signal to be transmitted thereby also increasing the likelihood that such a signal (i.e., protocol signal to be transmitted) will be detected.
