    • 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.
    • 本发明涉及一种用于在CDMA系统中设置导频信号传递功率的方法和装置。 订户单元(211,213,215)执行导频信号测量测量并将其发送到接收机(603)。 处理器(605)在测量期间至少部分地依赖于导频信号测量和用户单元(211,213,215)的小区重叠条件来确定每个小区的排序因子(217,219,221)。 处理器(605)根据排序因子排列小区(217,219,221),并且通过调整功率放大器(609)来响应于小区的排名来设置至少一个小区的导频信号发射功率。 确定小区重叠条件作为用户单元(211,213,215)的切换状态或者在测量期间由用户单元(211,213,215)可以接收的小区的数量本发明可应用于第三代蜂窝通信系统。

    • An optimisation apparatus (100) for optimising a spread spectrum cellular communication system comprises a measurement report processor (101) which collects measurement reports from remote units of the spread spectrum cellular communication system. The measurement report processor (101) is connected to a path loss processor (103) which determines relative path loss data for the remote units. The relative path loss data may comprise path loss data relative to a constant which is common for a plurality of neighbour cells of a remote unit. The path loss processor (103) is coupled to a model processor (105) which establishes a model of the cellular communication system in response to the relative path loss data. The model processor (105) is coupled to a performance data processor (109) which generates estimated performance data for the cellular communication system from the model. Estimated performance data may be generated for different parameter values and the optimum parameter value may be selected and applied to the cellular communication system.
