  • Patent number: 7272409
    Abstract: The invention relates to a method and apparatus for setting pilot signal transit powers in a CDMA system. Subscriber units (211,213,215) perform pilot signal measurement measurements and transmits these to a receiver (603). A processor (605) determines a ranking factor for each cell (217, 219,221) at least partly dependent on the pilot signal measurement and a cell overlap condition of the subscriber unit (211, 213, 215) during measurements. The processor (605) ranks the cells (217,219,221) according to the ranking factor, and sets the pilot signal transmit power of at least one cell in response to the ranking of the cells by adjusting a power amplifier (609). The cell overlap condition is determined as the handover state of the subscriber unit (211,213,215) or as the number of cells, which can be received by the subscriber unit (211,213,215) during the measurement The invention is applicable to 3rd generation cellular communication systems.

  • Patent number: 6628953
    Abstract: A remote unit (101) monitors a control channel for a base station (103) and sends a probe message (301) to the base station (103). The base station (103) forwards the probe message with location information (305) to a controller (115). The controller (115) determines an approximate distance for the remote unit (101). Based on the approximate distance, the controller (115) determines at least one additional site. A channel assignment message (309 or 401) is forwarded to the remote unit (101), which message includes one or more traffic channels associated with at least one of the base station (103) and the at least one additional site.

  • Patent number: 6192247
    Abstract: The present invention provides a method for extending the cell radius between a mobile station (101) and a base station (103). A propagation delay is determined between the mobile station (101) and the base station (103). A transmit time offset is determined for the mobile station (101). The transmit time offset is based at least in part upon the propagation delay. Information is then transmitted between the mobile station (101) and the base station (103) at the transmit time offset.
