Abstract: A method and apparatus for controlling an amount of downlink power to be applied in each downlink transmission in a macro diversity radio system. Downlink power level is controlled in response to a quality measurement of a corresponding uplink. In accordance with exemplary embodiments, a path gain or a carrier-to-interference ratio of an uplink is measured at a base station in an active set, and subsequently used to proportionally govern a downlink transmission power level for a corresponding downlink. In such a fashion, each downlink handling a mobile station maintains a desired level of robustness, while avoiding introduction of unnecessary system interference.

Abstract translation: 一种用于在宏分集无线电系统中控制在每个下行链路传输中应用的下行链路功率的量的方法和装置。 响应于相应上行链路的质量测量来控制下行链路功率电平。 根据示例性实施例，在活动集中的基站处测量上行链路的路径增益或载波干扰比，并且随后用于成比例地管理相应下行链路的下行链路传输功率电平。 以这种方式，处理移动站的每个下行链路保持期望的鲁棒性水平，同时避免引入不必要的系统干扰。
