Active set selection method for determining cells to be deleted from an active set based on the reception state of an uplink high-speed signal
InactiveUS20060116156A1MinimizingEfficient use ofAssess restrictionRadio transmissionRadio Network ControllerWireless network
Each base station measures the reception states of an uplink high-speed signal from mobile terminals and periodically reports the measurement results to a radio network controller (RNC). The RNC determines cells that are to be deleted from an active set based on the reception states (for example, the reception SIR) that are reported from each base station. The RNC transmits to one base station and mobile terminal a radio line release request for releasing the radio line of the uplink high-speed signal that has been set to a cell that has been determined as a cell to be deleted from the active set. The base station and mobile terminal that have received the radio line release request from the RNC each release the radio line, whereby the cells of other base stations are eliminated from the active set.

An improved beaconless adaptive optics system and process. A target is illuminated with a high energy laser beam of a directed energy laser. Wave front measurements are made of high energy laser beam reflections from the target. These wave front measurements are analyzed by a high speed processor to determine both high frequency phase components and low frequency phase components in the wave front data. (Applicants' experiments have shown that there is a direct correlation between beam spot size on the target and the phase variance of the reflected laser beam. The correlation is: the greater the phase variance the smaller the beam spot size.) Applicants have developed a technique for providing special control algorithms that provide very high speed control of the elements of a deformable mirror using this phase variance as a feedback parameter. Applicants have also developed algorithms to correct a limited number of Zernike modes associated with the wave front control.
