  • Patent number: 6728304
    Abstract: In a wireless communication system comprising an effective ray detector, a method for detecting and assigning a mobile station signal including receiving a plurality of search metrics, the plurality of search metrics including a plurality of offset energy values at corresponding time offsets, sorting the plurality of search metrics in order of their offset energy values, calculating a plurality of decoding success predictors, and selecting the decoding success predictor having the maximum value. The method also includes forwarding an acknowledgment message declaring signal detection to the mobile station if the maximum decoding success predictor has a value greater than zero. The method further includes assigning receiver demodulation at the time offsets associated with the maximum decoding success predictor if the maximum decoding success predictor has a value greater than zero.

  • Patent number: 6584325
    Abstract: The current invention relates to a cellular communication system. Known communication systems performs cell selection based on measurements of downlink pilot signal levels. However, this is inefficient as uplink conditions can have significant impact on the performance. In the current invention a subscriber unit (300) comprises receiving means (305) for receiving uplink characteristics information transmitted from a target set of base stations (201,203). The subscriber unit (300) further comprises base station selection means (309) for determining at least one serving base station in response to said uplink characteristics information, and transmitting means (311) for accessing the cellular communication system through said at least one serving base station. Preferably, the subscriber unit (300) comprises means for calculating an access message transmit power level and the base station having the lowest calculated access message transmit power level is selected.
